Best Battery from different roms and official releases. - Motorola Droid and Milestone General

Anyone have any views on which of all roms and official releases have best battery?
i think best gingerbread rom is iceandfire

As far as battery life is concerned, my oppinion, nothing beats a clean stock Eclair (official), followed closely by a clean stock Froyo (official). All mods are great, but battery life is better in the official ROMs in my own experience.

Are you serious?

iceandfire v2.1 is the best ROM I've found so far in terms of battery life. Don't know why, but it just lasts SO long!

I use ice and fire loads its good but I wish it could be a lot better, testing froyomod now, am considering buying a new phone mainly for battery life as the milestones is sooo bad!

As mentioned, nothing beats Eclair. And if we talk about Eclair, nothing beats Telus Lite.

I have CM7 installed.
Your battery mileage may vary depending on your usage habits... But I'm typically a pretty heavy user. Lots of Angry Birds/other games, surfing, Pandora, etc. I go to sleep at around 11pm with my phone unplugged at a full charge (100%), and I can use my phone until the next day mid to late afternoon - that's about 15-18 hours. Granted, a lot of it is when I'm asleep (until about 7am) and during my working hours, but it's still pretty decent considering how I use the phone. ESPECIALLY with all I've heard about CM7 having terrible battery life.
I DO have several apps and tweaks to try to lengthen my battery life though...
Some things you can do:
- install "Network Switcher" from the market. You can set conditions between certain hours and the screen off to turn off WiFi and 3G. I have mine set turn off all data between 11:15pm and 7:15am when the screen is off.
- install the "Toggle 2G" app. This automatically switches the phone to 2G mode when the screen is off. 2G typically sucks less juice than 3G. (get it here: http://forum.xda-developers.com/showthread.php?t=739530)
- tweak your /system/build.prop file so your wifi scan interval is a higher number. I have mine set to 360 seconds (that's 6 minutes). I don't know about you, but I don't need my wifi scanning every 15 seconds for an open or known signal.
- also in the build.prop file; change your ro.telephony.default_network setting from 3 to 0. 3 means GSM/WCDMA mode; 0 means WCDMA preferred. From everything I've read, WCMDA preferred tends to switch signal types less often, which benefits your battery.
Heck, even if you DON'T have a Milestone w/CM7 installed, these tweaks can help immensely with your battery life.

Froyo should beat out Gingerbread... They're roughly equal for me, but the memory issues of GB make me have to keep my phone on longer to wait for tasks to complete, thus draining more battery overall.

Yep, I've tried pretty much any Froyo and/or Ginger Bread mods (and I've specially liked CM7 / ShadowMOD, but all other ROMs are great as well), no one is close to the stock Froyo as far as battery life is concerned. But, I have to say, it is not absolutely stock, but, with exactly the same VSEL/CLOCK settings I've tried in other roms (which save some battery since it uses lower vsel).

That doesn't come remotely close to the V6 SuperCharger script.
The minfree levels is only one aspect of it.
AKMO doesn't fix groupings or priorities.
With those settings, all your apps are getting killed at 28 mb - because of the screwy groupings they are in the 5th slot while slot 3 are 4 are basically empty holes.
And that whole "banned rom" spiel is getting pretty annoying.
I'd bet money that HONO's SuperCharged CM7 kicks Cronos' ass with those AKMO settings.

zeppelinrox, have I offended u in anyway?
I have even introduced your method to calibrate battery to other people.
Why do u need to reply in such an arrogant and nasty tone towards me?

I agree with zeppelinrox, running his V6 supercharge scripts work wonders.
And no matter what ROM I use, i always use SetCPU to auto-adjust the processor speed based on certain scenarios. For example, I'm using CM7 right now, which auto overclocks to 1000mhz. That's great for performance but crappy on the battery. However, with SetCPU I can force the CPU to run between 250mhz and 400mhz when the screen is turned off. There's simply no need to let it go up to 1000mhz if I'm not even using the thing! Calls still come through fine, as do emails and messages. But it really extends your battery life. You can go as low as 125mhz, but then things do start messing up. As soon as the screen turns on, the phone is automatically allowed to run at 1000mhz again.
It's also useful for when your phone gets really hot, as a precaution. If my phone reaches 42*C it automatically underclocks as well. I picked that number out of a hat though. It's just a number I felt was too hot based on my own experience with the phone.

I think you're reading too much into it. I didn't think he was being arrogant/nasty. He was just being straight forward.
Just my 2 cents though

No not offended.
Everybody knows that gingerbread memory management is screwed up and fiddling with minfree levels alone ain't fixing anything.
AKMO alone does nothing to fix memory management it doesn't even tell you what apps are where.
One set of settings on one rom has a totally different effect on another rom.
The groupings in CM6 and froyo mod are nothing like CM7 and Cronos.
So those settings would make froyo roms dog slow but are kind of aggressive in CM7 and Cronos and of course do nothing to make the launcher more responsive in both cases.
The only way to know what kind of effect minfree levels would have is if you know where the apps are.
And the only way to be certain of where they are is to tell android where to put them.
Which is why the SuperCharger script works on all roms the same way... it puts apps in their place so that the OS will run in a predetermined and predictable fashion and therefore the lowmemorykiller settings will have the exact effect that the user expects.
So no, I'm not offended.
But kind of annoyed that I spent quite a number of weeks perfecting it and somebody who knows this is fiddling around with AKMO settings while they really truly can have a phone with fixed memory management.
btw, if you check the memory groupings with AMM, you will see that AKMO is annoyingly in memory way too often. Which is ridiculous.

Ah yes, now your tone of voice is much better... more professional and more matured as compared to when u said wrote b4.
Thank you for clearing this up.
Hope to see you back in Cronos forum as I recalled how much u were impressed with Cronos Ginger.

I check it out time to time.
Cronos is good and feeyo is cool but lack of updates, v1.2 had issues plus I needed to test other roms.
Btw the memory managent on cm7 and cronos mimics my strategy from v5 anyway - which was to give the laubcher its own OOM grouping/slot but everything else is just weirdly placed far down the list so still not as good as v5.
Tthen V6 simply out does v5 hands down.

Battery Drain Drach 2.7

I have done every possible thing i could think of to stop my battery drain:
first i had automatic task killer installed but it seemed as though that may be causing the drain
then i installed UV kernel and uninstalled automatic task killer and i thought it was getting better but it is now doing the exact same thing as before... about 1% every 5 minutes...without much use
i have the latest radio baseband (2.42.01.04.27) installed, but my battery stats are:
cell standby: 49%
phone idle: 43%
display: 10%
health: good
now i switched back to using automatic task killer WITH the UV Kernel but it doesnt look promising as my battery was going 2% every 5 minutes.
I tried to use setCPU but got a little confused setting things up so if that helps could someone please help me with that?
Thanks in advance for any help i get...
-Brian-
This is exactly my situation. I've been looking for a couple days for a solution, as I've been seeing people getting over a day with no CPU manager, no ATK or anything of that nature. Have you actually seen a difference with Task Killer on?
Now I'm just curious what could possibly be running?
yeah with the task killer running it seems to die slightly quicker... at least with UV kernel... prior to UV kernel the ATK actually helped a slight bit. My battery life just gets worse and worse... yesterday i was using wireless tether and it actaully LOST battery while charging because it was so hot. i have no idea what could be killing it.
Shame, I guess if I can't get this solved I'll have to go back to a non-OC Fresh build. Don't get me wrong, I really like FreshROM but I like the AOSPs so much better. I'm thinking my phone just doesn't like to be OC'd and I don't know if I can do with 10 hours worth of battery with minimal usage.
there were 2 thread about this already http://forum.xda-developers.com/showthread.php?t=704155&highlight=battery+darchdroid
http://forum.xda-developers.com/showthread.php?t=711462&highlight=battery+darchdroid
yes there are multiple threads and EVERY thread leads to the same response
"try reflashing your battery stats"
people have tried that and i still getting IDLE and standby at the same number
I know I am. I have tried all the different suggestions. I'm going to try using handcent again and getting away from the stock messenger to see if that is what is making my phone stay on.
it isnt, ive used handcent and chompSMS and i still get the same results with both.
Simple solution, use a different rom.
buncha wise guys in q and a. seriously though, why?
Sent from my Hero CDMA using Tapatalk
A simple response, yes, but Darchdroid is by a large margin my favorite ROM and I'd really like to use it. Especially considering the fact that DarchROM will be the first 2.2 rom out, it'd be nice to find the source of the problem now.
I'm back to Fresh2.3.3 (non OC) and my battery life appears to be great again. I'm almost curious enough to find a non OC kernel I can use with Darchdroid so I can have acceptable battery life and the UI I'd like.

[Q] CM6 vs Chronos Froyo Battery life

Hello,
Which one has longer battery life? From what I read, Chronos Froyo has longer battery life and also it's more responsive? Why is that?
Can CM6 use the same code as Chronos Froyo for speed and bat life?
I think it depends on overclocking.

I use HO!NO ROM for the CM6 and this weekend i realized that i was 22h without recharge it and was with 80% Battery. No profile set.. no Set CPU... Mobile Data 100% ON!!
I simply can´t understand, why every one has different battery life on same ROM. I know it depends on usage etc. but I´ve heard that HO!NO has huge battery drain
Battery performance is based on how one sets up his phone, overclocking, wifi / 3g usage, media usage etc. But on the same setup , cronos wins.
Ye, why Chronos is better? Isn't base on CM6 too? Or it has it's own modified kernel that's why it's better? Is bat life base on Kernel?

This is based on what exact versions being compared?
I have now tried Cronos for the sake of everyone prasing battery life. I compared every ROM over at least 3 days use and i can say there are no big ddifferences as far as battery life goes between CM 22.11. Froyo 2.0.1 or Cronos 1.6 update1. There is some fluctuation, but nothing too aperent.
Older versions had quite some battery problems, that holds for all ROMs, but now only abaut 20-30% less battery for me on these Froyo ROMs, than on eclair ROMs i had before. For first Froyo ROMs it was like 50% less...
Well, the CM6 on the actual build (0.04) is imho far the best concernig battery-life.
Just a little less good than on SHOLS_U2_36.0 by G.O.T.
Before it was probably Cronos, but nowadays the difference is down to the voltage selected. On Cronos this is lower, so out of the box it should take up less power. However, clock for clock it should essentially the same. The rapid releases of CM6 takes the cake for me
I tried both Cronos 1.6.1 and CM6 25/11, I noticed no great difference.. just a feeling, Cronos runs more smooth at same clock, but they are almost the same!
Sent from my Milestone using XDA App
In my personal experience, Cronos 1.6.1 is currently the best ROM both in terms of battery life and responsivity/relayability. With everything enabled (3G, wireless location service, gmail sync) , is the only ROM that can give me 18 hours plus of battery.

Exactly. I believe both hit battery life with the same tweaks. Then it comes down to the voltage and clock speeds. CM6 should last plenty long too.
Pretty much identical battery life. I use my phone quite heavily so never get more then about 16-18hours. Maybe in long haul there is a difference but not with a well used device.

this. although i haven't updated yet to the latest CM6. my phone once lasts from 2.5-3 days, with minimal mp3 listening and harcore wifi usage.
before the upgrade to cronos 1.6.1 (best froyo to customize) i was using telusV5...
eclair could last even 50 hours without recharge.
froyo is 25 hours at its best.
i use H data always on, gps on, latitude, whatsapp, wireless almost never, i make lots of calls, i read news, play games like angry birds or asphalt5 few minutes.
i tried every combo of mhz and vsel from 1100 74, to 700 46...no significant difference, battery lasts always 24-26 hours.
I use c.m. roms,from about the 10th of november or something,c.m. roms last about twice as much as my stock eclair did,i'm sorry to say that,but if nadlabak didnt exist,cronos wouldnt exist,feeyo is waiting each time for nadlabak to solve each problem and then he will release his own rom.
Whenever nadlabak doesnt publish his work,cronos is stuck...
Nice guy maybe feeyo,but not milestone expert...
I prefer the original thing,wich is more superior in my opinion...

Right but are you comparing it against a tweaked Froyo?
I used STOCK Telus 2.1 back in the day with the Overclock mod at 1000mhz/60vsel.
I used to push email from 8am to 6pm everyday at work. I had terrible reception at work so I would use 2G a lot during the day, but I would always have 30% AT LEAST by bedtime. I go to work at 8:30am and sleep around 12am.
Now I work at a different place, but I got into work at 11am today and left at 6pm. I took a break in the middle to get lunch, but since I work underground, I turn on airplane mode the whole time. It's now midnight (13 hrs since unplugging) and I'm at 40%. I'd say that if I had 50% of my time on airplane mode that's pretty bad. Other than that the other 6 hrs that I was out int he open I got decent reception. I just pushed gmail, sycned Facebook/Twitter hourly and weather every 3 hrs. Not too bad in terms of heavy use. Also I have the 2G toggle on. I just don't see how I'm draining battery this fast.
So in my case Eclair completely dominates. With HONO or TelusLite mod I probably got a little better battery life throughout the day. I dunno. I only had 1 month of work or so during the summer of using those ROMs before I quit and I stopped pushing exchange mail all day long.
You forget something battery gets worse over time. I had very good batery life on Eclair. Now i use Froyo for quite some while at begining veery bad battery life. Now latest releases quite better, but still not there so i went to try Eclair again for a bit and i found out even eclair doesnt have the battery life for me it used to have, battery is just old and its only half a year since i bought. But take this i charge it everydays ometimes more so in half a year a charged it around 200 times. 300times is the number i think battery gets quite worse.
Maybe one of you battery hawks can help me figure out what the major problem I'm having is.
I see people saying they get 24+ hours on a single charge, yet I have a difficult time maintaining 12 hours with minimal usage.
My provider (Bell Canada) does not have a 2G network I can fall back on, so that's one thing that could be causing major drain.
I am using SuperPower (but haven't noticed any major difference there), SetCPU to set processor to 250 when screen is on, 15sec before screen off, wifi off, GPS off, background data off when screen is off, auto-sync off, and data scheduled to be on for 5 minutes every hour.
I use my phone when I commute to check emails, play Angry Birds, and the like, and generally overclock to 700 or 800 Mhz, with 48 or 50 vsel depending.
Using my phone to play a game, check email, or surf the web for 10 minutes can cause it to drop 10-20%, and even when it's totally turned off overnight, if it's not plugged in it can drop to 20% or lower from a full charge just sitting on my end table.
Any suggestions/ideas?
EDIT: I wanted to add that I tend to use the most up to date CM mod, but have been trying Cronos since the battery life was touted so highly. Unfortunately, I find that Cronos drains the battery slightly faster than the 11.25 mod did. Testing the 11.29 version of CM6 currently.

Battery life between leaked Captivate Froyo and custom ROMs

I noticed battery life on ae leaked Captivate Froyo 2.2 build (with AT&T bloatwares intact) was stellar!!! The battery life nearly doubled the custom ROMs that I have tried (the latest Cognition 2.3b8 and Axura 2.3 ROms).
I have tried all three on a regular work schedule from 8am - 4pm in a same location. I left all the ROMs installed as is. Here are the battery life meter findings at the end of my shift listed by ROM:
1. Leaked Captivate Froyo 2.2 --- Battery Life (92%)
2. Axura 2.3 --- Battery Life (69%)
3. Cognition 2.3b8 --- Battery Life (65%)
Anyone know why is this? Don't get me wrong, I love the Axura new functions and all that extras built-in. However, the battery life is discouraging.
did you recalibrate the battery and delete the batterystats.bin each time you changed to a different ROM? also, im not sure but the different modems could be the cause of the battery drain.
I almost want to say this is common sense. If you load something that increases your phones speed with a lagfix, gives you stronger reception and faster download speeds with using a different modem, and has many more enabled options would you not think battery may be effected?
All this being said I can get 20 hrs of moderate use on my current configuration. I do not need much more then that

*almost*
I have questioned this myself sometimes, then realizing that there is a lagfix installed. it's like buying a Vette for the gas mileage.. not gonna happen.
Hence, some custom ROM's do have damn good battery life with lagfixes! So, it's just a matter of finding what suits your needs.
The issue I've been seeing with the latest builds of most of the ROMs in the Dev Forums are:
Using customized i9000 Kernels and Modems. These are hacks/tweaks (and very good ones) to work with Captivate phones.
OC/UV Kernels that offer awesome overclocking/voltage capabilities but at a price - battery usage.
Using a Vibrant build for Captivate phones.
Custom "Captivate Kernels" (sorry the quotes aren't there for sarcasm just emphasis) that are still in beta or development.
All of the above cause battery issues as they are not optimized for our phone, missing some bits in the software that handle the OS/battery life, or straight up bleed the battery to death as your OVERCLOCKING YOUR PHONE.
And to make it worse utilizing different modems just exacerbates the problem.
Lag Fixes - SHOULD NOT AFFECT BATTERY LIFE AS THEY ARE JUST CHANGING YOUR EXISTING FILE STRUCTURE IN YOUR PHONE.
So it does make sense that while using a "stock" ROM you would get better battery life.
Now.. on to battery life/usage:
Calibrating the battery helps at least keep a more accurate track of how your phone's battery performance is doing.
You can do a few things to optimize your battery usage:
Of course Calibrate your battery - removing battery stats on your phone, doing the drain it down to 0% and re-charge to 100% to ensure you have an accurate idead of true battery usage is always helpful. I delete battery stats right after every flash to a new ROM.
Turning off Wireless/GPS/Data etc. while not in use. This does NOT mean to use a task killer since if you have an errant app running it will just make battery life worse not better.
If your using an OC kernel - then the usually install Voltage Control is a must! I have heard great things about tweaking these settings and people getting great battery life from their devices. Now.. mind you you don't have to overclock if your running the OC kernel. It's just there if you want it.
Also - being careful of what you have installed on your phone is one of the biggest ones most people miss. If it's trying to do a push every 3 seconds that is utilizing your battery/proc and that will be killing your phone.
With all that being said though? The custom ROMs are all awesome and I'm very glad we have them - even if it means I sacrifice a little bit of battery performance (which to me is horrid to begin with). I use a little common sense and I can at least get through an entire day with average usage (txts, email, calls, xda, angry birds etc..) without having to throw it on a charger.
Sorry.. long post - too much coffee and 90 wpm does that to me sometimes

For battery stats - you go into the advanced Clockwork Recovery Menu - go to Advanced - and you should see Clear Battery Stats there.
I would make sure that your phone is charged to 100% before doing this.
There is another trick you can do also that works for some people.
Charge your phone in.. as SOON as you get the notification stating to unplug your phone you should unplug it - wait 30 seconds then plug it back in. If it wasn't calibrated correctly you will see the percentage on your battery typically at around 97% instead of the reported 100%.
The improved battery life can probably be most attributed to the difference between the Java interpreter in 2.1 and Froyo's JIT.
In short, when Java does interpretation, it reads a single application instruction, decides what to do with it, does it, and repeats. If the same function is encountered again, the interpreter still has to re-read the instructions, decide what to do again, and do it.
In comparison, when Froyo's JIT encounters an application function, it reads the instructions in a large batch, decides what all of them should do, and records the result in the processor's "native-language". If the same function is encountered again, the processor just does it without needing to make all of those decisions again.
The speed difference is more than 30x. Running application code is only a small fraction of the total "working time", so benchmarks typically only see about 3x improvement. For the parts that are running applications (including even the home screen), Froyo is ultimately running 1 operation that used to take 30 operations - that means fewer electrons are wasted on the processor.
Also, Samsung's crappy filesystem decision certainly will impact battery life, since the format they chose (a relative of the old DOS format) performs seeks optimized for linear mechanical devices (like hard drives), not from FLASH, which suffers on fractional block reads and excels at non-linear reads. Lots of electrons will be wasted interacting with FLASH unnecessairily, but that kind of interaction is rare compared to other battery consumers.

Reasons to Wait on CM7

Just wanted to gather together the current remaining problems with CM7. What apps don't work, what's unstable, etc...
It actually seems very stable for me. I like it more than nookie froyo. With the 1.1ghz kernel it runs very smooth with launcher pro.
Every app I've tried works fine, and best of all - they show up in the market.
Its definitely worth a try, you can always go.back to what you had if you don't like it - just make a backup.

Bawb3, are you using dalingrin's overclocked kernel? If so, are you able to mount your nook on your computer via USB? I just installed the kernel last night and I'm unable to get USB debugging to come up when I plug in. I tried on Windows 7 and OSX and nothing happened in either OS.
Other than that, I love CM7. I started out on Customized Nookie Froyo, but I was having major issues with scrolling speeds and weird market issues. So far CM7 has been rock solid and blazing fast. I would recommend you give it a go.
Just make sure you use one of the latest nightlies if you do. The customized versions are nice, but no one does CM7 like the actual team.
New NC user this week, I've been running CM7 on eMMC for about 48 hours (first nightly v12, now v13) and it's been very stable. DSP video is the major thing lacking. Flash is smooth (including Hulu). I am having some trouble with seeing my installed/purchased apps in the Market but there are work-arounds I haven't tried yet.
I noticed in v12, Google Reader worked 100% fine and Maps FC'd. Now in v13, Reader scales down to 480x320 as soon as I open an article, but maps works fine. I've read this is a problem with DPI settings but I haven't got around to fixing it.
Overall if you're sick of B&N's Android, CM7 on CWM 3.0.1.0 seems to be the most stable of all the ROM's I tried, even in its nightly stage. But I have read of other peeps having major problems. I just really love Gingerbread. Google has really got a winner with 2.3
battery life is horrible w/ CM7, lots of drain when sleeping.

I would be interested to see if anyone has flashed #14 and had Google Reader scale to full size in article view. I'm on #13 as well and haven't been able to get it to scale properly no matter what LCD Density I use.....

I'm not too concerned with the battery drain considering the tear downs have shown that the battery is plugged in and not soldered onto the board. By the time we kill these batteries with multiple charges someone will have put out a kit to replace the battery yourself...just like with the ipods that weren't supposed to have user replaceable batteries.

I second this, i notice it drains the battery pretty fast when im not using it. not really sure what it is doing. its not like its connected to the internet or doing something productive for the battery drain.

I turn off WiFi when I'm not using it (you could use Tasker to have it automagically go off/on at sleep/wake) and battery life improved significantly. I'm guessing when wifi is on, a lot of background activity happens.
But battery also isn't a big deal for me either. I probably use the thing for about an hour a day untethered, and the rest of the time it is plugged in.

It might be that an app like TweetDeck is scheduled to get updates every 3 minutes or something. I make sure to turn all of that stuff to manual as I pick up the Nook with checking it in mind anyway and can wait the few seconds it takes after I hit refresh.

Is battery life alot better in nookie froyo?

Yes, battery life was was a lot better in Froyo for me. However I had a load of other problems in Froyo such as market intermittently not working, wifi problems, flash not working in firefox. I am sure it could be fixed, but it worked out of the box in CM7 and I liked CM7 UI much better.
Is anyone running CM7 out of an sd card?
If you're seeing battery drain, it seems SetCPU profiles eat up a lot of CPU. Just use the inbuilt settings (Settings > Cyanogenmod Settings > Performance > CPU)
Dalingin posted a new kernel that supports USB mounting on N13+ and also a new Interactive governor which should be faster.
DSP is really the only thing missing. I replaced Google Reader with a dolphin bookmark to the smartphone site, which I feel works a bit better anyway.
I just watched the video below and am pretty close to loading this. I tried Nookie Froyo was wasn't happy at all. I actually like the rooted stock appearance and performance except for the lack of flash. I just wish these ROM's allowed me to make the home screen look like the stock experience with the "continue reading" options on top and the stock B&N reading/store app.

I'm running CM7 v13 and I feel like this is the best one overall. I had a few minor hiccups with the wifi but i found a work around to it.
Contrary to what people say, I am impressed with the battery life. This is why. The original NC is used as an e-reader, but i purchased it as a tablet. I haven't had alot of experience with it, but i was able to get at least 6 hard hours out of it with the OC. Left it on overnight (roughtly 6 hours) with wifi and battery only dropped like 5% which is pretty good to me.
The only gripe i have is the DSP but that's tolerable considering all the other advantages of it.
The xda community has been very helpful and alot of the quirks with it has already been worked out if you do some searching in the threads.
Just my 2 cents.

Quick question on the nightlies: If I update from lets say #13 to #14, does it erase everything I had installed? or is it just and update that keeps all the apps and settings?
I am on #13, and some problems I noticed:
- Wifi would go on and off by itself coming out of sleep
- The "clear" notification button is REALLY unresponsive (might be a hardware issue thou)
- Takes FOREVER to charge (more than 5 hours)

As long as you don't wipe your data (though do wipe your cache) before reflashing, it should keep everything. It kept everything for me from v12 to v13, and then kept everything from v13 to v14. You should always double check the important stuff though.
I have the same responsiveness problem with the Clear button, but I'm 99% certain that's the hardware. I have had response/accuracy problems consistently in the corners of my screen, especially the top. Since the problem was on stock, nookie froyo, and CM7 (it's actually a lot better on CM7 than stock), I'm guessing it's the touch panel's fault.
Charging goes a lot faster for me if I've got it plugged into a wall (like 2 hours for 30% to 100%) instead of my computer. Probably a lower current coming through the USB on my computer than from the wall plug, I get the same difference when charging my Milestone. Don't know why the ROM would affect charging at all.
The only main problem with CM7 is that video acceleration doesn't work. That means no Youtube app, Orb app, playing x264 files with the local player, etc.
That is a deal breaker for me, but if its not for you then.....

GALAXY Note: Battery life is so less. ?? (Please Help)

Hi everyone. My battery life is really sucks. I bought my item two days ago. It is new. And I upgrade my version and baseband , kernel and build version like below :
N70000XXLB2
2.6.35.7-N7000XXLC1-CL1003701 [email protected]#2
GINGERBREAD.XXLC1
I think that this version xxlc1 is last version but I wonder how is my kernel version ?
Battery life is very bad.
Moreover Charging lasts so long. 3 -4 hours sometimes.
PLEASE Help me! please
depends in the usage, rom, kernel, settings etc you are using.

when i see some kind of usage experiences, I am so jealous. How they use this much ? HOW. I only use wifi and radio.
Hi,
What is your battery life on the Note? Does it last a day even two?. If it does, then that is pretty much normal. You whine on a phone that you just use for only 2 days? Stop whining and complaining. You havent have had utilize the full charge and recharge cycles of your battery and now your whining already.. Man, give your Note a week or two and your battery life will be okay.
Hmm.. Is this the first time you use an android device? What phone where you using.before? If you we're using a non android device e.g. Symbian or etc. Then my reaction to your complains (of your Note) is justifiable. Symbian for the fact has always been known to be very good or decent in terms of battery life.
Now android OS, is known throughout (irregardless what smartphone/tablet you have) to have the AOS bug. It is a bug where there's some sort of a battery leak and hencefort most android users tend to root their phones so that they can stop background stock applications from running in the background. The births of custom ROMS and Kernels have given some tremendous wonders also especially on phone's UI and more so on battery management.
Again. Stop complaining and go down root your phone and install battery saving apps or custom ROMs. It's all over the thread anyway.
The sooner you customise your phone to your heart's content, the better you can appreciate it's full potentials.
Cheers!!!

My battery life is 5 - 6 hours. I am accept 12 hours. I wish it last 12 hours. Before I used Iphone4, it is not so long for battery life , however it is acceptable. I did not understand how notes's battery life so short.
Moreover I can not use custom rom. because they r not good as well as stock rom. ALl of them have some problems. But I can change my kernel.
to get battery life you either
a) dont use your phone or
b) get information to use your phone more wisely
So..
a) download a battery monitor.. there are a bunch recommended..
b) read the other 200 threads on battery life and dont start another one. Each and every question has been asked and answered ad nauseum
while you are figuring out root, and task killers, here are a few easy tips to help..particularly when you are putting the phone down for a while
apps>task manager>active apps> CLOSE ALL
apps>task manager> RAM> CLEAR MEMORY
settings>applications>running services> review and shut down apps/games that may be running in background (and that are not critical)
Again.... RESEARCH the forum.. the answers are already here. and you should read and post in existing threads

You could also have a defective battery.
On my iPhone 4, my first of 4 that were faulty, battery life depleted in less than 12 hours of STANDBY only on wifi, nothing syncing. Only being on. Battery life was so bad.
It's not uncommon to get a dud battery sometimes.
Try doing a complete restore, stock EVERYTHING, don't push anything (except email, cal, and contacts, you know, the basics) and see if you're having the same results. If on a fresh, stock, install you're having the same issues, then you've got a defective unit and/or battery.
Hope I've helped.

There are quite decent custom roms for the Note. I have tried many gingerbread versions (Chracks, rocketrom, cassies etc) currently on chrack's v18 small (LC1) with speedmod latest kernel.
I have not faced performance issues on this. But each user is different so u r the boss.
Best give the custom kernels a try for now. If u find the battery life better then ur problem is solved. The advantage of custom rom is that so much useless bloatware in the stock is removed for better space mgt & performance.
have provided some tips in the following link, feel free to go thru.

dude, you are ridiculing some of the well known devs who have made custom ROMS for all to appreciate and use. IF there was and is a problem on a particular custom ROM, it is or might be cause indirectly on the user itself, on what apps he/she insatalled on his phone. Surely you cannot generalize all custom ROMS have problems do you? if all have problems, the devs have some new revisions to fix those bugs and in no time at all your Note would be in tip-top shape again.
If as what you say, Custom Roms have problems.... then why the heck most people I know have used them and have big wide grin on their face to show off what they have and even posting a copy of their latest ROM pictures here... not to mentioned in YouTube as well.
ok. Which rom is the best stable than ? Which I should use ?
go read the threads on battery performance.. loading a new ROM will not fix problems if you do not know what you are doing.

first quote :laugh:
Hi there.
I had the same issues but only after the update done on ICS.
I have over 140 different application and nearly all of them have been purchased.
What happens is that, when you are not using your phone it should go to "deep sleep". This allows your phone not to run any application and merely use any battery. Your problem probably come from somewhere in your setting an automatic update. That drains a lot....
I downloaded different application hoping that it would work out such as Juice Defender, watch dog and many others. After lots of research, I found out that it is not good for your phone to have an auto killer app or even an application that modifies the functions of other applications.
So I downloaded battery spy and cpu spy on "google play" and followed the instructions.
I needed a deeper analytic application "Kernel" and this was THE application that allowed my phone to go from 6-8 hour to 28 hours.
"Better battery stats", it's not free but was really worth the spending.
Google play chronological download
1) watch dog
2) battery spy
3) cpu spy
4) better battery stats
Good luck
I keep switching my cellphone off while not using, and same goes for wifi. Using it as a secondary phone as well. It lasts only 4-6 hours.. :S I keep closing background apps, and kill app once im done with it..
Also be aware that in areas with bad network strenght, the GNote really suffers.
I normally have no complains (0,6-1,5% battery usage per hour) but where I am now, the GNote really works hard to keep the connection and my consumption easily goes to 4-6% in deep sleep and 15-20% when using it...

If you like stock samsung looks try CleaNote 3.10 , very good n battery life , I get around one day backup with heavy usage and 2 days plus with moderate usage .
If like pure google , then try cm9 , very stable and quite good on battery back up .
And if you dont use 3g or 3.5 g or any such networks then select GSM only or use 2g networks only ( Settings -> under wireless and connectivity , More -> Mobile Networks )
Also keep your display brightness to minimum , control the brightness manually instead of auto brightness .
Turn off auto sync ( big advantage over battery ) .
Scan for running apps and cached apps and force stop the ones which you dont use .
Use titanium back up and freeze some of the bloatwares ( stock samsung apps ) or uninstall them , like readers hub , mydiary , they are **** .
And dont use task killers , they drain your battery . they may clear rom but some apps restart automatically and that needs more juice than running those apps . Hope all these suggestions help . From my experience with this phone

I didnt know that, My signal is usually 10-40%. I have bad signal strenght at home.
my battery decreases 1% in around 5 minutes of use or something. Today it lasted me 10% on standby for around 8-10hours.

You need to purchase and install "better battery stats" and also install cpu spy (I'm assuming you're rooted) and use them to monitor your phone and battery in order to solve your issue. Google both and you'll find several good threads on xda about using and interpreting these apps, but if you get stuck post some screen shots from both and someone here can almost certainly help. There are a number of potential sources of such problems, generally rogue apps, and also a bug or two, but it is impossible to offer help without the details these apps would provide.

Thanks for that, i will install it. By the way i got the "battery widget" installed, which has gained popularity on the market.
Also im only using 9% of brightness of my phone.
I'm using a rooted stock 4.0.3 and I'm finding battery life its pretty good - better than unrooted GB was in fact. Simply freezing bloatware via titanium and limiting sync on some (not all) apps and services makes a gigantic difference. Design your phone around your own needs and you'll end up with an amazing device that you'll fall in love with all over again.
