Seems to be an inordinate amount of dissatisfaction with "this ROM" or "that Radio" due to perceived sudden battery drain.
I believe that I have far more variance in battery drain, day to day with the same setup, than I have due to changing ROM or Radio.
I have sometimes run the exact same setup for several days in a row, yet one day it will seem like battery is lasting forever, and another day it seems that battery is draining very rapidly.
IMHO, of all the criteria of importance in evaluating a new ROM or Radio, battery drain is towards the bottom of the list. Just like my laptop, I make sure that I always am prepared to renew my charge - I have a charger at the office, at home, and in the car - at all times! My Wizard is my everyday tool, and function and stability are way more important than battery life. I plug in and gas up whenever I get the chance, so I have never had an issue with running out of juice!
My opinion is that charge and drain cycles, and program use, probably account for 90% of the perceived variance.
Am I the only one that thinks that battery drain issues are over-hyped?

Your probably not the only one who thinks the issue is over-hyped ,that said it is very much an important issue. I'm not sure that I would list it at the top of my must haves list but isn't anywhere near the bottom. A stable working rom is what matters most but what use is it if requires you keep a spare battery in pocket to use it. These variances are certainly not figments of our imagination as I have seen my wizard go from lasting 3 days to less than one with no change in the useage profile.
I've never had an issue with battery drain. But -- like you -- I keep my Wizard "topped off" with a charger at my desk at work, in the car and a desktop cradle/charger at home. When my battery life drops below 80% it goes on the charger wherever I am.
I also find that my battery life is in direct relation to running apps/Today plugins more than ROM issues. So, if I don't run some of the more power-intensive apps, my battery lasts longer.
That's my story and I'm sticking to it. . .
Typically there is one or more programs that cause the battery to drop quickly. I know that recently after I performed a hard reset on my x-bow install (Orwell's), my battery drain problems went away. However, when I restored the backup, they came back so I went ahead and performed another hard reset, and installed all my programs one by one again. After a couple of times doing this, the problem finally went away. Believe me, it got so aggravating at one point that I switched back to AKU 3.2. I did install the 02.61.11 radio rom, and I think that may have helped.
The issue is not overhyped. I know that it happens, but a lot can be resolved by being patient with what we install and when we do it.

Hi Actually, yesterday I took my phone from the charger at 100% at 7AM, by 6PM I had less than 50%. Only used it twice for a regular call and a couple of texst messages. Today it is a lot better. It alternates between fast drain on one day and then another day it could be good. I am using Faria's V2 rom, 8mb pool. As far as the memory leak in Faria's V1, a beta version of today agenda came out that I am using on Faria's V2 and have not had memory leak issues. All in all, it's a great rom, even if it has the battery issues, Cingular did a crappy job with the original rom.
ROM upgrades
ROM upgrades reset the battery history, so that it has to learn how long it lasts. This makes for a lot of variance in battery percentage, but not in voltage; all it is doing is learning how voltage translates into battery duration. Usually just a day or two after a new ROM and battery drop stabilizes. But it never learns perfectly -- my battery stays at 100% for hours and then starts falling a percent or two an hour.
Wifi uses up a lot of power. Just being connected to a bluetooth headset doesn't seem to use much but if it is searching for the headset (e.g. because it is off) then it uses a lot of power, although not as much as wifi. Searching for GSM also uses a lot of power and if I know I will be out of touch for a long period of time I turn off the phone, but just being connected to GSM doesn't seem to use much.
on a thread i read to use the device unlocked option, it worked for me
Exactly, the biggest factors for battery usage are (apart from wifi and using applications of course):
1) reception quality
2) data connection
example 1: London, crap reception at home, average usage, two mailboxes checking mail every 5mins, gprs always on : 7am - 100%, 8pm - 25%
example 2: Same as above but one email checked every 15min, second every 30min : 7am - 100%, 8pm - 50%
example 3: Egypt, reception always excellent, no data connection, usage SLIGHTLY less: 7am - 100%, 8pm - 94%!!!
Anyway, that's the price for the performance I guess, if the battery life would be the most important thing, I would buy Nokia 6310...
Here's an amazing discovery. My phone was at 25% in about 8 hours. I will leave the phone at 100% at night and it will be at 75% the next morning. By chance I purchased a brand new battery to place in another phone that had a broken usb. I placed the brand new battery in my old phone to charge it and at 100% I removed it and placed my old battery and charged it to 100%. Now I leave my phone at 100% at night and the next morning its at 100%. Go figure...... Overnight, the phone radio is on and so is bluetooth
Suspicion, drain rate is a memory issue....... comments

I totaly agree, I have my PDA hooked to Exchange with wireless active sync and full attachment download. If I was to say get 5 emails with 10 MB attachments, and then have a 2 hour conversation with some one I haven't talked to in a while I would most definately use more of my charge that day.
The point is that to me battery drain is more about usage either perceived or not. I set my PDA to do whatever it wants, so that is what it does.
One thing that i have noticed is how you charge your Phone. I have noticed that if i charge my phone with the home wall charger i'll have to charge later that night. But if i charge it thru the USB cord from my computer, the phone stays charged for almost 2 days. Thats why i only charge my phone now thru the usb cable. if you dont believe try it out and you will be amazed.

that's quite strange - definitely not the case for me...
well everyone i work with here has a pocket pc and i told them to try that out and they actually noticed a difference in how long the battery would stay charged even with regular usage of the device. So either this must work or im a real good manipulator.
Hello, I've recieved my AT&T Tilt 8925 (Kais100) unit a week ago and ever since I've experienced awful battery performance. The item shipped new (not refurbished supposedly nor defective) and included a Samsung battery. I changed to Dutty's v3 ROM right away (flashing was successful, I also switched to radio version 1.27.12.27) and last night switched to Q-Mobile v1.2 to see if the ROM was the problem, but it persisted.
My battery drains extremely fast, even when the unit is off it drops 10% after 8 hours (overnight and also throughout the day, I'm leaving the unit at home while I solve this issue and it's always off). The unit does not have a SIM card inserted and the Phone function remains off, so does WiFi, Bluetooth, Beam, 3G, etc. It's also muted and has no alarms activated, nor background programs running (I'm currently running a freshly flashed Q-Mobile v1.2 ROM with a hard reset done as well).
I've read about battery perfomance extensively but haven't ever read about the battery discharging while the unit is off, and given the fact that I'm NOT using the phone functions, I barely believe this can be normal behaviour. I purchased 2 units from the same source and both are having similar issues with battery perfomance.
I'm currently testing a borrowed OEM Dynapack battery from a friend's Tilt to see if it shows the same behaviour as well to discard the possibility of a faulty unit. Note that I'm using the OEM 1A charger and leave the unit charging for several hours.
If the battery proves to be defective I'd have to get one (or contact the seller to see if he'd respond to the issue). Can someone recommend a cheap/reliable battery that could be bought online (eBay, etc.)?
Thank you very much! I hope that someone has a clue on this issue.
Best regards
Sebastian
Just to clarify, is the phone actually OFF, or is it in standby? If it's in standby, 10% after 8 hours wouldn't be unreasonable at all.
Uhm, it's on standby I guess (when I turn it on again it's instantaneous, not like when you soft reset the unit)...
I'm new to PDA phones, I had an IPAQ RX3715 before with WM2003SE and I could leave the unit off for days without battery drainage. However I may not be too familiarised with these new units' standby/off functioning. If in standby and with the Phone function off (meaning that the device has "nothing to do" other than being off) it's normal for the device to drain the battery so much I would be disappointed.
As a sidenote, my friend's Tilt is not draining while it's on standby being on the same conditions other than the fact that his unit has the Dynapack battery.
Regards!
Bat Drain
I have the same rom and the same problem. I was at the hospital all day i made two calls and about mid day my bat was at 30%. I think its duttys rom V3 causing the problems. Changing roms now.
I could be wrong, but I think your phone is fine, these devices just consume a lot of power. 10% over 8 hours would be totally normal in my opinion. Is that the main reason that leads you to think there is a problem with your phone? Have you ever had a pocket PC before that had better battery life? When I got my first PDA I thought the same thing, but I realized that they are not like normal cell phones, where you could just recharge once every couple of days. PDA's must be charged at least every night. If you use GPS or wi-fi a lot you're probably going to be charging sometime throughout the day as well. I just got into the habit of plugging it in every time I get into the car, and when I get home I plug it into either the computer or the wall charger. There are after market batteries available, but if you want a drastic increase in amp-hours, the battery is going to be bigger and it will require a new battery cover. This is totally unacceptable in my opinion, as the device is relatively large to begin with. My advice would be to only activate a radio if you are using it, and de-activate it when you are done. Also just get into a routine where you are charging it whenever possible. Another thing, I just flashed Dutty's V4 RTM, and I must say the increase in battery life was very noticeable. Don't let me confuse you, though. From the information you supplied, I really am not able to tell if there is a problem or not, so give some more information and examples of battery life so we can figure out if somethings wrong, or if you just aren't used to the amount of consumption of this type of device. Hope I could help. Cheers!

Yeah that's not normal. You got any radios besides phone running throughout the day?
Thanks for your thorough reply. Picking on what you mentioned, it's true that I'm new to PDA Phones, as I mentioned I also own an iPAQ rx3715 with WM2003SE and my idea was to replace it. Judging the fact that PDA-only devices, to my eyes, are nowadays dying I thought I'd get me the latest and most complete device available WITH GPS, since I was using my iPAQ together with a GPS Bluetooth Receiver with much delight.
What I experienced with my previous device was that battery performance was never an issue, it did consume power as any PDA, but I didn't find myself worrying about it, it never dropped when off and it would last me several days.
Since I'm using my Tilt with the Phone function off I _thought_ it wouldn't need any power for anything... but it might be that these new devices, or the new WM6 architecture is different to that of WM2003SE/PDA only devices... I don't know, but it just sounds strange to me, although if it's normal I'll live with it- as you say, I'll have to be charging it 1-2 times a day.
On the one hand it would be good for me to know that my device is ok, but on the other hand it means that battery life isn't even close to what I expected... I had read people complaining about it but in general I tend not to be overly critic about the defects of devices... but it seems that it's the case. I meant not to use the phone features and thus I thought it wouldn't be consuming power on standby seeing that the phone should not be running anything on background...
Thank you again for your reply. If anybody else has a word on this I'd appreciate it.
Best regards
Just as an aside you will notice the battery life getting better after a couple weeks it seems the battery has to be conditioned so to speak. Also do you have any kind of push email on your phone as if you do that does use quite a bit of power, you might want to set it up as a pop3 account and set it to check emails every so often instead of getting them as soon as they come in.But I have amde it a habit to always use my charger whenever I am able to as these batteries seem to be happiest when topped off whenever possible.
Hello again, I'm still experiencing this problem and it seems not normal.
Simply put, I fully charge the device. I turn it off. It discharges by itself with all wireless functions off.
Today I did a hard suspend (keeping off pressed) with battery at 60%... when I turn the unit on 7 hours later the battery was at 6% with a critical warning sign.
I'm NOT using the device, I turn it on, use WiFI for 3-5 minutes then switch it off and put the device to suspend. I turn it on after a couple of hours, play with the menus and turn it off again. Just by doing that the battery drains by 10% every 5 hours or so, sometimes it won't even turn on due to battery drainage.
Is this NORMAL? I need to know if my unit or my battery is defective so I can return it to the seller in time...
Thanks, best regards
Sebastian
Battery life DOES seem to improve with time. The first day my battery wouldn't last for 5 hours! Keep charging your battery and letting it drain as much as you can (whether or not to let it fully drain is debatable), and I bet you'll see some guaranteed performance.
Also, what would help a lot is if you found and installed the Today plugin BatteryStatus and checked the "Show More indicators" option, and see what your battery drain was. The normal is between 150mA and 300mA when you're on the Today screen. Any more than that, and you most likely have a problem, assuming connections besides phone are off.
sounds normal to me, turning off you mean by pressing the button on the right side of unit? if so, mine is the same way
I'd say that was definitely not normal performance. On average, I use mine for at least an hour worth of talk time, an hour or two running TomTom, numerous SMSs, and at least a couple of hours reading books. I charge it every night, and the battery is generally running at around 50 to 60% by that time. I'm surprised at how quickly yours is draining.
I have an RX3715 inhabiting a drawer, and, while the battery life was a lot longer on that device, the battery was a lot larger, and the screen lower quality. The fact that it is not connected to a mobile network gives the battery a much longer life too. When I used it purely for TomTom, connecting to a bluetooth receiver, the battery faded very fast.
I've had a Kaiser since day one. I have found that adding a comm manager that allows forcing the phone to Edge give huge battery savings. In standby with the phone radio On and BT radio ON, WiFi OFF, my phone drops 4% over night very consistant. On Edge battery lasts days.
The only time I get fairly high battery consumption is streaming with 3G. Edge is so much more efficient on the battery, so if you don't need the speed, throttle down!
The only time I've ever found the phone Dead or close to dead after only a few hours on standby was when I had WiFi ON and the phone in standby. I can't pinpoint what exactly causes the condition, but when it occurs, the phone is HOT and the battery heavily drained in a short time. This has happened with both Hermes and Kaiser. I never leave WiFi ON when not needed, and have never seen severe battery drain since.
I do sometimes turn off all radios except WiFi, and then use wired ear buds and stream Slingbox video to the phone over my home WiFi LAN. I can get almost 4 hours of watching on a charge.
The battery should not be draining when powered off, but not much at all when put in sleep mode. Get yourself a replacement Testing.
As an aside, Alex's WM 6.1 BETA 2 has given me the best battery life of any rom. Only about 25% of the battery drains per day. With most other roms it's 50-100% per day.
Hello, thanks to everyone for your replies. It's strange because I've been doing lots of test, switching batteries (I have 4 units to test now) and I get inconsistent results... the 2 most problematic units were bought from the same eBay seller and got their ROMs changed the first day, the 3rd unit still has the AT&T ROM and was apparently not draining as fast. The problem is that the 2 first units seem to get battery drains overnight in flight mode of 10% and 2 times one of them got a 0% critical battery status just by being in standby and not in use (none of them are working as phones and have the function off)
The odd part is that for some reason this happens only sometimes, now I've switched to Sleuth's WM6.1 ROM and the problem is gone for now, I'm still at 90% since 2 nights ago having turned on GPS and WIFI for 5 minutes each 2-3 times... the other 2 units have been in standby from 100% charge and they haven't dropped either! And they're using the AT&T ROM and Q-Mobile v1.2 respectively... what kills me is that I cannot say what's wrong, cause I've swapped batteries, swapped chargers, swapped ROMs but cannot trace which is the problem (or if there's a problem at all)...
Perhaps it's normal for the unit to sometimes drain 10% after 8 hours of standby in flight mode and on other times remain at 90% for 2-3 days if not in use...
Thanks everyone for the read, I'd appreciate any comments
Regards
Sebastian
What radios are u using. Try changing radios
10% loss overnight in standby would be normal.
Does the unit get warm when you notice rapid drain?
I wonder about the "old" active sync problem - does the device show any running programs when you turn on?
In general you should expect to get a days worth of power using it for the odd call, perhaps an hour of wifi and perhaps an hour of prgram use. Of course all taht is very variable but I generally get away with a charge once a day. Occasionally, I take it from it's holder and it's warm to touch, but usually it's 'cos I've forgotten and left something like tomtom running.

Hi guys,
Recently installed GPRS monitor that came with HTC tytn II... and on the main screen theres a little indicator telling you your battery life...
Mine reaches a maximum of 3:00... 3 hours?! is this normal????
can anyone shed light on this?
I usually have the phone connect to a laptop so I am not sure what my battery life is...
Joe
Mines starts with 1.5 hours but last few days......dont know why but this spb gprs monitor (the version that came with my o2 Stellar) used to work great, for some reason it does not work anymore......well the battery life indication bit any ways....
battery life is only an estimate when used in optimum conditions with only standard usage so i wouldnt worry about it too much unless you notice it drain as fast as it states
i think i read somewhere in the kaiser forum that sometimes with gps reciever turned on there is some abnormal battery power drainage .. Other day i was using google maps with gps turned on and my battery went from 100 to 25% in half an hour .. yikes. However haven't had it happen using yesterday and this morning. Battery at 80% currently no charge.
hope this helps shed some light.
peace,

i flashed my Diamond 3 times since i bought it 1 month ago.
i started with 1.34 ita, then 1.37 ita, 1.93 ita and now i'm on SwiftBL-WWE-Diamond-ROM-v5.6.
Diamond is my work phone, now i am in holidays so i do not use it all day long but it is turned on for eventual calls.
Since i put 1.93 and still now with swiftBL i notice that the battery life is shorter. At now, in stand by mode, only keeping it turned on, the battery lasts less then 5 hours. With 1.37, making calls sendig sms life was around 6hours or more.
I must charge my phone 2 times a day and put for another charge near midnight before go to bed for all night long. Batteries like charge cicles but now im thinking this is too much stress for diamond battery.
do u think it is broken? how long is your diamond phone battery life?
i probably buy another battery and a car charger so i can charge it in any place, but i would be glad for more efficency.
anyone of you knows how much thick is extended battery?
thanks for answers
There are pictures of the extended battery in the accessories forum - pretty much where you would expect to see them.
That does sound like odd behaviour to me though for your battery. If I don't touch my GPS, make a couple of brief calls and send a few texts, whilst keeping in 2g mode, I expect to see about 40hours from a charge.
I'm experiencing a similar behavior with 1.93 ROM and 1.00.25.05 radio firm.
I'm currently wondering if S2U2 is the cause.
_Mystique_, do you use S2U2 ?
I use S2U2 with mine - I have been using the new radio and ROM from Dutty.
Just in standby with push mail on the battery lasted of 36 hours from friday. sundays charge lasted only 24 with the same usage? apart from 10 mins on teeter
i had about the same issue - i was charging it about twice a day to keep it going. i took it back to phones4u in here in the UK - after a bit of discussion and getting an error code from Orange - they gave me a new one - and its about 50 times better! the battery lasts much longer and the signal is better! my theory is that i had a faulty aireal or something - it had terrible reception, and because of that, more battery power was used trying to get a signal... But i might be wrong!

Hi
I had this issue as well, until I have stop sync my calendar
I do not understand why, but for now I am not sync it
i have a Diamond branded "TIM", and also my battery last about 10 hour without using the phone, always in standby.
I tried switching off the phone module and the battery last about 40h.
So for sure the problem is the aerial/phone component.
I will send the mine to htc in warranty, because i think that 10 hour in stand by is not the normal behaviur of this phone.
also i tried 2 spare "chinese" battery, from ebay, but all the results are the same.... so for sure aren't the battery.
Bye
Question:
I'm going to get my Diamond soon. How long the battery must be charged for the first time? 3 hours or more?
Why it is not good to empty the partially charged battery and then refill it to 100%?

i have partially solved the problem
yes, i use s2u2, but the real problem (for me) is Kaspersky Mobile. Closing it im experiencing 100% plus battery live: i ended a complete charge at 14.48 at now (21.52) i am at 50% battery.
So the problem are the running tasks. This time i closed kaspersky and s2u2, then i will check if i can close some SwiftBL default task
i am in 3g mode (i've switched off hsdpa), bt always off.

i think that is normal that more battery is spent with phone mode enabled.
i think that a realistic battery life target is a work day.
on ebay there are batteries (10$) and craddles...
Beware of these cheap batteries.
Especially for GPS, that seems to need genuine batteries to work well.
Other topics already deal with this.
Hey all, I'm new here since I just bought a used G1 on Craigslist after losing my previous phone, so this is my first Android phone. I rooted it and I've been messing around with the phone for the past week.
Everything's been working pretty well, but my battery behaves strangely. I'm current running BiffmodV2.1 on 2.22.28.25 using ezterry's kernel. I just did a clean wipe and calibrated the battery too.
The problem is, when it's sleeping (I put the end button behavior to sleep) it uses barely any battery. I leave it in sleep mode overnight and it goes down by maybe 2% tops. However, the second I start using it, the battery starts draining like crazy. It uses maybe 1% for every 1-2 mins I'm using the phone. I turned everything off (wifi, gps, data (I disabled data because I don't have a data plan), background data, sync), turned screen to dimmest, and setCPU to 528mhz. Even with all this, it still drains severely. When I use it for music with the screen off, it uses about 1% battery every 10 minutes, much better than the drain is nowhere near what it is when the screen is on (minimal use without music). When I put it to sleep with Wifi enabled, it also barely drains any battery, but same thing happens when it's awake.
Does anyone know a possible solution to this? I also recently bought a 1400mAh battery, but it's most likely coming tomorrow. The current battery is pretty old, it's the stock battery that the previous owner has been using for the past 2 years, but even then, it doesn't explain the difference in the battery drain.
TL;DR G1 battery drains like a mother when awake, uses almost no battery when asleep even with music playing. Looking for a fix.
EDIT: I also tried Super D 1.11, Chromatic, Cyanogen, and a few others. All had the same exact issue.
I'm having this exact same issue, my phone also turns off randomly when I'm using it. I didn't have this issue when using radio 2.22.27.08.

When I use it for music with the screen off, it uses about 1% battery every 10 minutes, much better than the drain is nowhere near what it is when the screen is on (minimal use without music). When I put it to sleep with Wifi enabled, it also barely drains any battery, but same thing happens when it's awake.
Does anyone know a possible solution to this? I also recently bought a 1400mAh battery, but it's most likely coming tomorrow. The current battery is pretty old, it's the stock battery that the previous owner has been using for the past 2 years, but even then, it doesn't explain the difference in the battery drain.
TL;DR G1 battery drains like a mother when awake, uses almost no battery when asleep even with music playing. Looking for a fix.
EDIT: I also tried Super D 1.11, Chromatic, Cyanogen, and a few others. All had the same exact issue.

Sounds like it's time for a new battery. It cant be the rom doing it since you've flashed so many and it still does the same thing. Try out your new battery when it come I'm pretty sure that'll fix it.
Got my new battery, and things are much better. It still drains a bit fast with the screen on and doing stuff (texting, browsing, etc) but the battery life is much better now. I'm guessing the new battery fixed it!
