hi guys im running firebird rom and my battery life sucks really bad. i take it out of charge at 10am and it dies around 4.30pm so does kernel makes battery life bad?
my kernel says : 2.6.32.9 [email protected] #28
please share
Depends. Some kernels are overclocked and will use more battery. Some are poorly put together and will use more battery. Some may not work well with one ROM, but great with another. Not knowing what you do with your phone it is hard to point a finger at the kernel. Poor reception, lots of wifi on time, lots of screen on time, GPS use, push e-mail...lots of things take battery. You need to see what it is you're using and whether that and not the kernel is your issue.
Short answer is yes, kernel affects the battery. All you can do is try a few different ones and see which is best for your usage.
im on messenger services and about 40-50 text and 3 mins of calls and my 3g on and brightness all the way down. no gps no bluetooth or wifi. i use the phone pretty much straight from 10am with maybe 2 mins here and there screen off

Well, what more do you want? With that kind of usage I doubt you can do much better with any ROM.
that kinda sux but if the screen is really on that much it is normal, i dont think any rom has been tested to surpass 6 hours screen on time.
one good rom was andromda with which i had a hard time running my battery down in a single day, usually went 2 without a problem and i do a lot of texting. also an old version of perception built off a bell vibrant i9000m rom was outstanding.
kernels affect battery life but clock speed on the cpu has less to do with it than many people think, the assumption is faster cpu speeds means more power drawn but the cpu is governed, the governor setting have a lot to do with it. think about it, is it better for the cpu to take 4 seconds on an operation @ 600mhz or do the same operation in 2 seconds @1.2ghz? depends on alot of things reallly but thew difference is alot smaller than people expect. there is also kernelhz which i dont know much about but reportedly if set down to 100 to match another frequency(cant remember off the top of my head) will increase battery life.
the kernel controls many aspects of the system but i haven't seen a kernel that has had a huge increase in battery life given the same rom since the 2.1 days. and even then the battery life wasnt as good as a couple of the 2.2 roms. it seems to me that the rom has more to do with battery life. some vibrant ports have severe battery drain issues on the captivate. some i9000 ports have amazing batery life but most are about the same as stock to slightly better.
if battery life is a problem first you want to see if any processes keep the phone from sleeping. figure out what apps show in the running process list and try killing them, if they don't die/they start back up then freeze them in titanium backup and see if anything makes a difference. careful freezing system processes, some are not detrimental, most are.
other tips are to try apps that manage 3g like juice defender. and use wifi when you can 3g is a bigger battery hog than wifi. also there may be a way to set the phone to default to edge instead of 3g but i think it varies with the build of the rom, you will have to research that one.
other things to look at is weather you sync to google, facebook, twitter ect. those feeds widgets can eat battery as well as the sync process. weather widgets like beautiful widgets seem to have an effect on some of the vibrant ports i used but not as noticable on other roms.
Yikes...that is some awful battery life. I'm surprised because speedmod (and it's variants) is pretty well accepted as being the best kernel for battery life. There are many threads around here for improving battery life. I have personally found that my biggest battery user was constantly checking how much battery I had used.
If you are barely turning your screen off that is good battery life. You will never make it much past 5hrs screen time. Where people get like 40hrs on a charge is when the phone its not actually used, and their set up has good standby performance

When I used assonance I would get three days of battery life.

As some have said screen time is the single biggest battery user. My phone will last for about 3 hours of screen on time. So I could have my phone die in 3 hours, or 2 days, it all depends on how often I'm turning that screen on.

Yeah, I would say if you're not getting at least 3 hours screen time then you aren't using your phone that much.

Not if you're in a bad reception area.
This is what I average on Andromeda. Some wifi, some GPS tracking, lots of music streaming via BT.
Of course, nearly everything comes into play. Modem, ROM, use, etc.

I apologize if this is in the wrong place. I've flashed a few ROMs, and I haven't been impressed with battery life yet. Some are obviously better than others but I have yet to see these day long battery life days even after calibrating battery and clearing battery stats and anything that's recommended.
I've started carrying a 2nd battery since I'm in the middle of coaching season and we take a good number of long trips in which I want to stream music or play games, etc while riding on the bus.
Can I get some opinions from those that have tried different ROMs on which gave you the absolute best battery life?
Def in the wrong place.
Wrong place plus this question has been asked and answered to death. Try searching and you will find your answers.

I havent a clue what your talking about i get 2 to 3 days out of many ROMs with medium useage best i seem to get is from Dilli,s rom and GB v.4 kernel UV 100 across the board this one i get 2 to 3 days of use with no bugs a few other ROMs have few things that dont work that i need, this ROM covers my needs and is fast good on batt very good choice for me.
is possible If u haved 3 or 4 hours of srceen time and some major texting and calling, and few hours of music u may never get good batt life depends how u use your phone.
I dont do more then 5 or 6 texts a day 5 or 6 calls a day i do use music app and headphones with screen off for about 4 to 8 hours the more i use the less i get this combo i use drains slow when i get to 10% and under it seems to hang on for hours before it dies all the way.
If you short charge your batt all the time u will kill it in a matter of weeks, U could have a bad battery or 2
Cycleing a batt all the way to full and all the way dead atleast 1 time a week or more batt life will be better
If you short charge your batt all the time it will get batt memory and only use the part of the batt you charge and disscharge to so if your useing 50% of your batt the it will only charge 50% if u use close to 100% it will charge to that.
Is true of all batterys car batt phone batts and so on.
I will tell u this me and my kid had same phone about 5 years ago because she short charged her phone all the time it would never last more then 5 or 6 hours yet mine would last 4 days with out chargeing.
we traded batterys and ofc she uses phone more them me it only lasted 2 1/4 days on that charge. but proves what i am telling u.
she learned from then on take the time and charge your phone to full and discharge as close to dead as u can.
easiest fix is do like i do i charge use 2 days near end of 2nd day i play a long vid till it dies the charge over night. and repeat i can go longer then 2 days but figer it is easier to charge over nite.
I also turn off gps,autorotate,data,bluetooth,wifi,also set wifi to sleep when screen is off, i turn off search for networks, i use a batt widget set screen to dimmest setting. and all the other stuff to save battery.

I agree with you and have found this to be particularly true of some of the newer ROMs, my guess would be bad Kernel/Modem pairings, best advice is to pick a ROM with a large number of users since the support will be better for those ROMs and continue to experiment with compatible Kernel/Modem combinations for that ROM until you find the optimum one for your device/location
I searched and looked in the Q&A forum. I can't find more than 3-4 people agreeing that X ROM has the best battery life. Then a couple people will say "no, this ROM has better battery life." But for the most part unless I just missed a massive thread, the battery ROM question threads don't get a lot of answers.
I was mainly looking at if I got 100 people (throwing out a random number) to answer which ROM gave them the best battery life, I might start seeing certain ROMs which have better batter life than others without having to flash a bunch of different ROMs.

It depends more on the apps and stats of your phone... are you running at full brightness? are there apps preventing your phone from sleeping? What is your wifi sleep policy? How is your signal, or are you getting the 50% Time-without-signal bug?
I'm running serendipity and get over 24 hrs. my usage is a couple hours of listening to music with poweramp, maybe 50 texts throughout the day, some gaming and facebooking.
I also havent cleared battery stats in weeks (although I've been on serendipity for about a couple weeks now). After flashing it at full battery, i just let it run to shutdown a couple times.
Some kernels are built for battery, and some apps or settings can be optimized for battery. Anything substantial will likely be included in pretty much every ROM, once it's known.
The main factor is that your battery meter is likely to act unpredictably for the first few days after you flash a ROM.

You have no idea what you're talking about.
Sent from my Captivate
((Please leave out any discussions about the "dangers" of updating in this thread))
So I updated via the leaked OTA 3 days ago and all is well so far. My battery has definitely improved by two fold (doubled). Prior to update my D3 would only go about half a day on light usage. Now it goes past 24 hours easy and could most likely push 36 hours (light use, wifi on 24/7).
However today I actually have been using my device quite a bit. Nothing heavy, really just organizing home screens and other duties of the sort.
So I look into my battery usage and after 6 hours my battery is at 40-50% with the display consuming a large amount of the battery. Brightness is at Automatic and the display itself has been on for 3 hours while using 50% of the battery. Is this normal or should % usage be more dispered between the running programs? I imagine the way battery usage stats work is that there will always be a program at the top with 40-50%... but maybe im (dead) wrong?
Also, how has your battery been since update?
(TL; DR) Display is raping my battery post-update, sup?

Edit: Dunno why the pics came out blurry, its fine in my system. Btw im using the (official) extended battery
Divide by zero, I dare you...
...Battery just hit 5% after 8 hours and 4 hours of display on. It unbelievably dropped from 15% to 5% with no brightness in less than a half hour, oh and I was in airplane mode. Literally all I've been doing since I turned my phone on today is have music playing and tweak my homescreen settings.
On standby the battery kicks ass but wow if I actually want to use my phone, the battery is as good as dead.
Im going to try out the standard battery that came with my D3 tomorrow and see if I get better results. Maybe its just my extended battery that's faulty.
If that fails then there has to be something wrong with the way my display draws juice from the battery... and ill probably have to get a replacement ... fml ... those crappy refurbed phones.
Divide by zero, I dare you...
Battery life for me is mostly improved. I say mostly because in weak coverage areas this thing destroys battery life fast! 20% or more per hour kind of fast. Still better than stock, but not much in weak coverage.
Strong coverage areas, phone is much improved for battery life. Seems to be a baseband issue. Hint hint Moto.
What I have noticed the most, is that my data roaming enabled setting actually sticks now, even if i lose coverage. For me, that was one of the biggest things against this phone. It made my data so impossible to stay connected, it almost wasn't woth having.
I too have the official Moto extended battery, but i still struggle to get 24 hours out of my device with very mild usage. For example, i am at 15 hours now, no wi-fi usage, no bluetooth usage, both off, cdma mode only and display on time of 23 minutes total for that time. I'm now at 15%.
My other phones, 2 Eris, and 1 Inc2, get anywhere from 2.5-4 days on this kind of use. I am thinking about ditching this battery monger for an Inc2 until Moto gets their shnizit together, or CM7 is available via a custom recovery and unlocked bootloader.
I am loving having my data available without needing to recheck the data roaming box 100 times a day, and other fixes. I am glad i used the leaked update, as my phone was close to a brick without it anyhow.
Now all we need is the new soak test update to ensure we're official...my gut tells me we are.
Anyone else having issues with Swype predicting in Spanish after the leaked update was applied? Only happens in one app for me, so far.

Lol the thing is I live in NYC so there are no weak coverage areas except the subway and I put my phone in airplane mode during those times.
Im sure we wont have any problems updating when the new OTA hits (whether through legit ways or otherwise)

The battery icon is misleading after the update. 60% - 70% reads more like 80% or 90%

Yes.
The battery stats (system reported percentage) appear unchanged, it's just the rendering of the stock icon that seems to be different.
*EDIT*
I use Battery Circle, as it reports in increments of 1%. I'm sure there are others.
Post-update, my battery usage has been noticeably improved. Before updating, it seemed that my battery drained at about the same rate regardless of how much or how little I actually used the phone (excepting major battery hogs, like fancy games or navigation). Now, the drop, when not being used, is significantly slower compared to before. Battery drain when actually using the phone seems about the same. So, overall, I'd say the processes like phone idle and cell standby have been optimized to great success.
-SR-
PS: "Display" now consistently lands at the top of the usage list, as is to be expected, and is much more believable than before the update.

Totally agree. My battery seems about the same if I actually use my phone but on standby my phone lasts like a champ.
I tried using my standard battery today and it lasted half as long as my extended one. Still, I doubt there's anything physically wrong with my phone... I guess batteries just suck all around lol

That's with 85% left.
Also, I love that the battery symbol is fixed now. It pissed me off seeing the battery lose a bar when it hit 94%. Threw me off so bad.

I'm not getting nearly the battery life that others are claiming.
I just calibrated my battery this time, so we'll see how it goes.
Please post a screen shot of your 'settings -> about phone -> battery usage' and click on display and tell us the 'time on' numbers.
I have about 2 hours of 'time on' time, and I've gone through a third of my battery. And I have very conservative screen settings. I don't see any way I could get the reported 9 hours of video time that Engadget reported.
I'm not complaining though - on my mytouch 4g, I could get probably 3-4 hours of screen time on a battery. Considering how powerful this phone is, and the size/resolution of the screen...... No real complaints.
- Frank
P.S. Can you imagine a hyperion extended battery? The stock mytouch 4g battery is 1400, and the hyperion extended is 3500. So a hyperion extended battery for the note would be ..... 6250 mah??!?!? [email protected] What we need is an ibm 'slice' type of battery - that wouldn't add much thickness.

Battery Life is one of my top priorities, which is why this phone seems to be amazing. I would like to hear from more users about this..
I can't wait until ICS & devs start making ROMs & kernel for the Note. I think then, we will see the Note truly shine.

What kind of battery life test would satisfy you then?
For instance:
I have used a variety of phones over the last 6 months (BB Torch 9800, Torch 9810, BB Bold 9700, Bold 9900, Galaxy 7" Tab P1000, HTC WP7 Mozart) and none of these devices can deal with my pattern of usage every day without at LEAST 2 full depletions and recharges of the battery.
I'm looking to the Note to be the first phone that can last a day, or at LEAST a day with only one recharge.
Engadget reckoned they got 9 hours of video playback on one charge. I do hope that this is indicative of the notes performance...

I am a heavy user. The only battery test I want is if the batter has juice left in it when you are ready to go to bed. I have a 4G Infuse, the POS would die in 6 hours. So lame.

Your post doesn't tell how the battery life is good. The part that consume the most of the juice is the display and I can see from your post that the screen of your Note was awake just for a little time...
So, trying a browsing and video experience would give us a better idea

I can tell you right now just by looking at the screenshot you have something keeping your phone awake. No way in the world is Android OS supposed to be that high. Figure out what it is and you'll definitely see better battery life. 90% positive it's an app you installed.

That's a known ROM/kernel bug in Gingerbread, with AOS taking up so much time. It will be fixed in custom ROMs - though who knows if Samsung will fix theirs ??
Battery tip, if you have NO SIM card in, "cell standby" will tear through your battery in no time. Put it in airplane mode, then enable wifi FTW.
I'm having the same problem. Really frustrating. Needing a recharge every 12 hours or so. And I'm not a heavy user :-/
Dear all,
Today I change a animate wallpaper to static, the result is good, my battery level after same hour, same use is much better.
Before, I full charge at nigh, start use the phone from 7am, web, email at cafe to 8am, have some phone call, email, and web again from 9pm to 11pm.
With animated wallpaper, at 11pm battery is 0, but today, its still at 50%, its good!

Animated wallpapers are battery death unless they are pseudo animations like that melting droid wallpaper which is effectively a giant battery meter. It's like playing a movie constantly.
When judging battery life, you should take in account that if you just have bought the device, you maybe are using it more than you will in the future. (I said maybe, don't jump at me )
I did... And I got 12 hrs or something.... I think that I will manage a good day with it in the future.
Of course the largest consumer of juice will be the screen... So, use a low brightness whenever you can.
And, I bought Juice Defender + from the Market, this seems a good investment and works fine on the Note. (Free version does too)

I can live with a data connection that just every 15 minutes goes on to check mail etc.
(although some people complain when they don't hear from me within a minute )

The battery on my Note is decent, giving me 2-3 days of moderate use or roughly a full day with heavy use.
Problem is when the battery decreases to around 40% & lower, the battery drains like anything even when not used.
Simply idling the phone would lose roughly 5-6% over an hour.
When the battery is around 20% it will easily run down to 10% and less over a period of a few hours when doing NOTHING.
Yet when then battery is at 80 & 90% it will lose around 5-6% battery over many hours.
Here is the proof, I took a screenshot of the battery information & you will clearly see rapid drops in battery life when at 50% and less.
On the last 20% it goes down even faster, and this is with NO use at all.
I hope this is fixed in ICS as it's a serious problem.

Pretty flat at the end there, even while being used.
I have seen that reported elsewhere, but not seen it on my own Note. I have just settled it into a new pattern after rooting and deleting the stats, so I am not certain right now, but I think it remains fairly even over the whole cycle.
I am not sure I could use is as little as you appear to have however!
I've yet to get my Note battery to last until 2 days, and not even a full 24 hours (almost heavy usage on data network).
So I guess that's good enough that yours lasted for almost 3 days!

Haha, don't get me wrong, I think the battery is great.
I'm only wondering why it goes so quickly when it's at 40% and under...
This seems odd. I'd say I'm having the same issue (the poor battery performance).
I've been trying to analyse this but don't have much time to do it right. From what I'm seeing the battery usage graph looks legit. Phone seems to enter deep sleep states. Nonetheless Note seems to drain the battery a lot faster in deep sleep than my Galaxy 3 does, which is odd considering Note having 3 times larger battery capacity.
What seems odd too is extremely slow suspend/resume cycles (e.g. the time it takes for the phone to turn the screen off/show lock screen). It takes more than a second on my Note to show the lock screen. I've seen other report this too. A friend of mine shocked a salesman on a Samsung booth lately when he showed him that. Galaxy S2 is thunderfast, while Galaxy Note takes ages to resume. My Galaxy 3 takes <0.5s. I've looked into the `dmesg` output for some hints. I'm no guru in this, but `ehci` seems to be taking some time to suspend/resume. This also converges with my other observation - Galaxy Note notoriously locks up when playing with usb host. I've tried couple of keyboard/mouse on usb - some of them do work, some of them don't (I can see 'Mouse/Keyboard' connected on the statusbar but there's no mouse pointer nor keyboard input is possible; after some time it's most likely to hard lock the system).
Thus I would suspect buggy usb host/otg hardware/driver that's leading to such a poor battery performance. But hey, maybe it's just me and my theories. Nevertheless something must be broken.
My battery is terrible.
With soe usage, mostly data, I'll drop from 100% to 60% in 3 to 4 hours.
Im on rocket rom.
Only 1 heavy gmail syncing and 3 other gmails with barely an email per week and facebook syncing.
And microsoft exchange calendar syncing (no email syncing).
No twitter.
No other apps.
But im on H+ most of the time.

I know HSPA (H+) eats battery because I turned off my data for 2 days and battery latest me 1.5 days.

I just made a suggestion, that's all. I'm trying to help you save battery. If you want all the bells and whistles and want battery then going for the extended battery is your route. I don't think you will get much more from the standard.
I have had troubles with battery life since I bought this beauty. I have been trying several Roms and Kernels, and none seem to make much difference. I also tried selecting among governors but still no better luck.
When I have 20-24hrs battery life it is very good!
The only thing that allowed me to save some was to reduce lcd intensity, and use the Note in dark environments.
Maybe I am using it more than the average user, but with all the opportunities it provides, I can hardly refrain myself from using it.
My typical use is:
- Radio and surf when going to work and home,
- Email and surf every hour at work
- About 10-20mn phone calls
- Listening to music when I can be alone working (1-2 hrs each day)
- Tablet use when at home.
Do you consider this to be a very heavy usage of the phone ?
I have just had my Note for a few days. The biggest battery eater in my case is WiFi. If I switch it off, the discharge is quite acceptable (a couple of percent during the night). I am not deep into Android internals, but it seems my 5-year-old Palm TX had much better WiFi power management than my brand new Note!
BTW, I am on a stock ROM and have disabled auto-sync.
Have you tried wiping battery stats? Let the phone completely die then charge it without interruption until it's been on 100% for an hour then boot to CWM and wipe battery stats

I do not consider the battery able to cope with the features.
I'm on H+. why wont I have everything auto syncing?
Battery should support the phone features.
Rght now I'm always connected to a power source via USB or car charger or home charger.

I can complain. I paid $750 for it.
The bells and whistles are there but the battery can't cope. Major flaw in battery implementation.
I already told the other guy i appreciate his help but that defeats the purpose of such an advanced and sophisticated mobile phone.
I had a SE symbian for 3 years then several HTC WM 6 mobiles, then a year of HTC Desire then an iPhone 4 for 1.5 years. I'll head towards the best regardless of brand.
Quit being a fanboy.

I am not complaining about the battery drainage per-se.
My previous phone was a Nokia N900, which I used all day long for calls, mails, radio listening, ssh to my home computer, etc... and I knew well that I could not use it for more than a day without charging, sometimes even less.
The phone battery was never advertized as being able to cope with such usage, and only announced battery times for 2G/3G calls.
When I first read announcements about the N7000, I read that Samsung decided to increase the battery power to make it last 2 days, which looked nice to me.
Now I have hardly 13 hours of battery time with my usage (see my previous post) and I want to know:
- is it a normal behaviour for the phone?
- is there a way to make things better with the same hardware?
- do I really need to lower my expectations?
If the answer to the last question is yes, I will be of course disappointed but I can cope with it, as I did with my previous phones. As CorruptedSanity already mentioned, my only complains are to the Samsung techs (or advertizers) and not to any member of this forum who are usually able to help beyond my needs.
I hope that screen optimizations will come that will increase the battery life while I use the phone, but my expectations are low.
You can expect around 5 hrs of screen time based on peoples reports here

Yup, that's the killer IMO. I can leave WiFi enabled all day, or use the phone for a couple of hours of calls and a few hours of 'screen time'. Not both!
Before rooting and killing bloatware, I could do neither.
Hello
I want to buy in the near future this interesting smartphone and I am interested about the battery life on the device.
So If some of you already have this phone please make a short battery life review.
Thank you

Interesting point of view
@ ducatisto
Thanks for sharing your opinion about the phone
Still I want more opinions about the battery life on this phone.
Probably I will buy this phone anyway just to test the quad core cpu.
I hope to notice a small diference betwen my current phone (LG-P940) and the P880.

This is totally bull****! From the owner and personal experience I can assure you that his 20-25 hours of activity makes them without any problem. Even with moderate use!
I will say the battery seems to be like all other smartphones.
I don't see a problem because I'm used to charge it once a day..

Using a fixed brightness is pointless if you want to compare across devices. What is 50% on some devices might be 70% on others.
The only way to truly compare would be to use a brightness meter on a reference image to set brightnesses the same on two devices.
It has already been said that the Optimus 4X is much brighter than most LCDs, and I'd be inclined to agree, it really helps for sunlight legibility.
Low battery life
I experience the same problem. I am a heavy user of the phone so the screen is on often.
My experience is too much comparable with my previous phone, the sony xperia x10 which has a battery issue.
My phone becomes also very hot while charging. I never experienced this with a phone so much as with this one.
I will factory reset the phone and perform a battery test. I will keep you posted.
Have you updated your phone ?
The v10b update is supposed to fix the battery and heat issues.
I am on version v10b and after like 10 charging cycles i must conclude that battery life suks

I have v10b and I tested it with antutu tester in different kind of situations.
In all situations the back and front (glass) got really warm. Nice in the winter but not if it cost my battery
I have the testresults attached.

Battery life is as bad as my previous ip4S, just managed to last one day after 4 charging cycles It gets a bit warm when surfing the internet and during charging. My version is V10c.
Update your phone. The battery life is improved with v10d firmware.

Not for me unfortunly, the v10d update doesn't fix the battery issue.

have you wiped the device before/after the update, i did booth, wiped before and after the update, will check battery live
after a few full loads, but overnight i lose around 12% with data (GSM) and wifi on (wifi on only when charging or screen on)
in 9 hours...
i think we can only get better results if we get root and custom kernels / roms .....
