Hi All - Did a search but couldn't find much about any 'battery life' problems with this device.
I'm experiencing poor battery life on my new XDA IIi. This is my second machine (o2 replaced the forst one due to poor battery lifery life and dead pixels on screen)
I just wondered what others are experiencing...I tend to have the phone switched from 8am til 6pm. The signal strength is good and I have wifi and bluetooth turned off.
Here is a typical set of figures for the battery through the course of my typical day
8am 100%
9am 84%
10am 75%
11am 61%
12am 50%
1pm 41%
2pm 32%
3pm 19%
4pm 11%
5pm 6%
6pm 3%
O2 say that the battery is at fault...but they've changed the battery twice and the unit once, and it's much the same. My guess is that something is draining the battery, but there's nothing special about my set up as far as I know. it's running a 1 gig SD card...but I took that out to see if it made a difference - it doesn't
Even with the phone switched OFF for extended periods of time, the battery doesn't seem to survive the day - I certainly cannot get to 8pm in the evening without having to charge it up.
I just wonder if the behaviour is fairly normal! If someone else out there is able to offer me some advice, or better still, some comparable figures, that would be helpful - just so I know it's not just me!!! ))
Alternatively has any one got any suggestiosn as to what might be draining the battery? (I'm always in a strong signal area for the phone)
Thanks
Hi I also have an XDAIIi.
My battery seems to be a lot more stronger than yours :?
If I don't use my XDAIIi at all, it can last about 4 days on standby, by this I mean phone on, wi-fi and bluetooth off. I have installed a LOT of applications on it and nothing seems to drain the battery.
My backlight is on full, my SD Card is always in.
If I use the phone say for about 30 minutes every night, then it lasts for about 3 days, still as the set-up above.
I find that if I am constantly using it, it will last about a day.
I am probably being pedantic, but as you probably know, rechagable batteries, in particular Li-Ion. Then they benefit from being run-down completely and leaving dis-charged for about 12 hours, then trying to turn them on again, (i.e. soft re-set) and then leaving them to turn off (almost instantly) Then whilst the XDAIIi is in it's "dead state" put it on charge using the mains charger and leaving it charging for about 3-4 hours. Then take it off charge and turn it on again.
Batteries don't like being half charged then run down a little then charger again.
Also the complete run-down time of a battery will only reach it's fullest after a couple of run-down and full re-charges.
This is what I do.
Hope it helps.

ps. the strenth of your signal should not make any difference. I am also in a strong signal area.
Battery...
Wow! Yours seems much better than mine with batteries. I just can't figure out what's wrong here and its very frsustrating - new battery..new XDA2i seems to make no difference, so it MUST be something I'm running...but there's nothing running in the background at all...very strange
Thanks anyway..at least I know it IS possible to get better battery life

Just out of interest, what mAh is your battery which came with your XDAIIi.
Mine is the standard 1300mAh
Lydiachris
ps. write me a list of what software you are running.
pps. Kettering??? Very near me Peterborough!!!
Battery woes...
MIne came with a 1300...but I bought a spare via the O2 shop that came with a 1200 :?:
I've got hundreds of progs on the XDA. Do you mean a list of ones that are running on startup?
Thanks
PS USed to live in Werrington!
do you have bluetooth or wifi or both turned on all day ?
is the pda on all the time or off and only the phone on ?
is gprs turned on all day ?
IR is it set to recieve all incomming beams?
how long before the backlight turn itself off ?
how bright is the backlight set to be ?
many many factors
Battery troubles
do you have bluetooth or wifi or both turned on all day ?
Both OFF
is the pda on all the time or off and only the phone on ?
Phone scheduled to be ON between 9 and 7pm
is gprs turned on all day ?
..Nope
IR is it set to recieve all incomming beams?
..Nope it's Off
how long before the backlight turn itself off ?
..1 minute
how bright is the backlight set to be ?
..about as low as it can go :lol:
As you can see, I've switched OFF most things to get drainage down to a minimum. As this is my SECOND device (o2 replaced the first one - same problem) and I'm trying out a second battery...my deduction is that it *MUST* be software related. I may be wrong and I'm hoping someone can point me in a different/new direction
I had a lot of hair when I bough this device - now I've very little left :wink:
Make sure lock all buttons is engaged, second set turn lcd off after 30 sec, third turn off device after 1 minute and you should be dialed in. If this does not work, preform a hard reset then repeat process. Do not install any additional apps/progs! Now if it works try installing one proggy at a time and test the device. It is most likley that there is a program running a daemon that is killing your XDA-IIi
Mikee
One more note. If you do a hard reset, which if I where you, I would, pay attention to the setup screen on the hard reset. When you see the O2 personal user corporate user screen, preform a soft reset with your stylus immediately! Then you will not get the O2 garbage and Icons.

hi
just got a xda2i and my battery doesent last long also my car phone charger wont charge it up quickly enough when its being used i took loads of stuff of but no difference.
regards kevin
Thanks Mikee
Hi Mikee
Thanks for your advice. I'm a little uinlcelar how a hard reset will help. This is NEW machine, I only got it last week. How does a HARD reset help the bettery management?
Make sure lock all buttons is engaged,
Done
second set turn lcd off after 30 sec,
Done
third turn off device after 1 minute
Already switches off after a minute
and you should be dialed in.
ehhh?
not sure what you mean

There is a fault with your device - under Consumer Service Guarentee you can return and have it replaced immediately as these goods are definetly NOT fit for purpose.
Mind you, you should hard-reset and double-check, but I'd say you've got a lemon flavour there.
Tkae heart, if you're the only one then it should be easy to fix!
My XDA ws the same when i first got it ... i'd deffo agree that the battery needs to be "optimised"
after a week or so you should notice a difference.
Heavy use of mine, ie listening to ,mp3s all day will take it down to about 15% (9 till 4 ish)
I have WIFI , bluetooth off
screen to the lowest brightness
power off after 30 seconds
[edit]
I just thought ..... You dont have the "Turbo mode" on do you ?
Battery on XDAIIi
Hi Guys - Thanks for your advice. What I find hard to believe is that this is the SECOND device where the battery life is c***. All my instincts tell me it's NOT the device - this is the second one they've sent me - nor the battery (as I'm now on my THIRD one)
I really want to avoid a hard reset because of the time taken to reinstal everything afterwards. I lead a very busy business life :? , and I just don't have the time to 'start from scratch'
...but I guess I will, if enough people tell me a hard reset will sort it :wink:
i did a hard reset but it didnt make a difference and when i spoke to 02 they were very quick to exchange it and when i spoke to the guy he said i should expect it to crash every so often like windows does on a computer i disagreed with this abd explained my xda2sw didnt crash like this one did.
regards kevin
stevep, in that case why don't u just make a complete backup of ur IIi, then perform a hard reset..
Sometimes the apps installed are the cause.. Also take note that switching to 'Turbo Mode' all the time will drain the batt pretty fast..
Battery drain - hard reset
Thanks for your reply - it's appreciated...but I don't understand how a hard reset helps. Yes, I can back it all and restore it, but surely that'll just put the problem back on the XDA (if it's an app thats causing the drain) :wink:
Can anyone explain (from a techy point of view) how a hard reset MIGHT corrrect the battery drain problem :shock:
Have you checked your turbo button under start, settings, power and then the processor speed? if you set it on turbo, it will eat up the battery VERY FAST. If else, I am using one and I am Happy with the battery life.
I've actually tested it with turbo 'on' and 'off' and I didn't notice much difference either way. It's actually on 'standard' currently

backlight - min??
turn off the backlight after 30sec??
button lock except power button??
I have recently purchased a Mugen 3000 mA battery. I am thrilled with the extended battery life after fully charging and discharging it three times as recommended by the manufacturer. What I find annoying is that WM6 no longer gives accurate information regarding remaining battery strength. If I run the battery down to 2%, remove the battery and restart WM6 says 37%. At 2% I can repeat and WM6 still says 37%. After running down to 2% a third time and repeating WM6 says around 10%. After that it varies a bit but you get the picture.
What I would like to know is if one of you geniuses out there has discovered a registry edit, hack or 3rd party software that will provide accurate battery info so I don't have to be distracted by having my battery say 2% for hours on end or repeatedly remove and restart.
BTW, BatteryStatus Ver. 1.04.200 beta2 build 0173 reports the same incorrect info and so does SPB Mobile Shell 1.5 Home Tab.
Thanks in advance for your informed guidance. OK, that is laying it on a bit thick but I always highly recommend this site to anyone I know interested in really learning how to take full advantage of that little computer in their pocket.
Take a search on XDA for Ariel monitor maybe it solves your problem.
Thanks for the suggestion. It is a nice little program but it suffers from the same problem. I suspect I need to find a way to change the mA capacity WM6 bases it's battery calculations. I don't know if that can be done with a registry edit or if there is a third party battery monitor that has an option to change the battery capacity for calculation of percentage remaining or better yet auto detects the actual battery capacity. Ideally it would be able to both accurately read remaining percentage and make reasonably accurate time remaining estimates based on current and historical battery drain data.
It is like driving a car with a broken gas gage. Sure, you can use the odometer to estimate how much gas you have left but you are always worried your estimate is off and you will be left stranded without a phone ... oops crossed metaphors.
How do the rest of the users with extended batteries handle this irritating situation?
Bump. I can't believe i'm the only one with this problem.
I know this problem also i will wait with buying a high capacy battery until i find such a hack
The Kaiser uses a smartbattery. The battery capacity is based on the information that a small processor inside the battery tells the phone's main processor. There are several things that could be the problem:
1. The small processor in the 3rd party battery is programmed with the old specs for the standard battery. The is nothing you could do about this.
2. The small processor needs to be calibrated. You would do this as follows; set your phone to never turn off no matter how low the battery got. Now, run the phone down until the thing dies from lack of power. Then charge it all the way up. This should fix that issue. I don't recomend doing it many times, because it is not good for Lion batteries to be fully discharged too often.
This is a very valid issue which I have faced many times when using a 3rd party extended battery with other phones.
Not sure how to solve it though, although I have the 3000mah on order myself.
I think the battery reading is given by the battery itself, and most of these 3rd party manufacturers don't really care to put a smart processor in the battery (to reduce costs/make it smaller/etc).
I have the exact same issue and although it is a nuisance, I have found a workaround to keep using the phone. Simply physically removing the battery and replacing it will increase your remaining battery power substantially. I normally wait till the first low battery reminder to do this. Also, how do I set the phone to never turn off no matter how low the battery gets? This would also be fine with me.

I didn't run into this issue until I reflashed my ROM to one with W6.1. Then, rather than get 12-13 hrs with my 3amp battery, I'd get 6. I used my original battery, but when I put the 3amp back in, I still had 47% left.
It's the ROM, and until there's a fix, it would be a pain to pull and replace the battery just to work around. I've done this several times recently when I'm on battery power, but I'd rather not.
Anybody heard of any other fixes, outside monitor, or do we wait until we get a Windows Mobile 6.1 fix?
Still no luck?
Hello,
Has anyone been able to find a solution for this. I am ordering the extended battery today. I will try to fully discharge it and then recharge it as was suggested and report back.
I emailed Mugen. We went back and forth with them trying to troubleshoot whether it's the battery or OS. They were clueless, but did offer an RMA to replace the battery. I pay the postage. Not sure if I'll send it back if it's the OS. I pull and replace the battery right now. It's a real pain, and I hate opening the case so much, but it's the only way I can get an accurate read.

The processor is required for these types of lithium ion batteries because it regulates the charging of the battery. If it didn't the battery would not charge properly, or maybe not even charge at all.
There is no solution for now, people from other forums tries to patch battdrvr.dll.
But two things may help a little:
1.You may completely disable battery monitoring
HKLM\Drivers\BuiltIn\Battery rename or remove string battdrvr.dll
But you lost monitoring completely.
2. change HKLM\Drivers\BuiltIn\Battery\Order change value from 15 (in my case) to 0. - After this battery lasts longer until power off.
There is not complete hardware or software solution for this problem. We need to wait.
Low Battery warning:
By default, a PPC will sound a warning sound when the battery is running low (10%, fixed value), but there's no way to disable or change the notification. To enable this, so that it is visible in the "Sounds & Notifications" control panel, set:
HKCU\ControlPanel\Notifications\{A877D663-239C-47a7-9304-0D347F580408}\Default = "Low battery warning" (REGSZ string, no quotes)
Anybody have any updates on this? I have noticed this more on WM6.1, but it was still an issue on WM6. I just find this so annoying!
Is there any radio that can fix this? I noiced that this battery reading issue only occurs when the Phone Signal is on. When off, it never happens to me. Or it seems. So it has something to do with the radio.
bump, anyone got a solution?
this is very interesting, i bought the seidio 3200 battery i am having the same problems. i just tired the
change HKLM\Drivers\BuiltIn\Battery\Order change value from 15 (in my case) to 0
i am going to see how that works out throughout the day
Tried It
I am having same issue, reset the registry key to "0" and ran for a full day, no change, still incorrect reading. I have a 2700 Mah battery and the charge indicater is completely wrong on it. I have cycled the battery as per reccoemndations, but still get wrong power remaining readings. Can remove the battery and resets itselft to a more correct reading.
I am out of ideas, guess we need someone from HTC to chime in with a hardware fix.

i have tried it too and it still does the same thing. i would still need to pull the battery and restart the device for the batt meter to get a more accurate reading. i could do it about 3 times before the battery dies completely.
is there this problem with all extended batteries or just with the larger ones?
the reason I ask is that I've got a $17 credit at Amazon and was thinking of grabbing a 1600mah battery, it's only like $22 with ship so I'll only pay a few bucks for it really...
I wanted to get the larger one but it's fat and won't fit standard carrying case, but the 1600 is slim and will fit in place a regular battery
Hey guys,
First of, YES I USED THE SEARCH FUNCTION .
My battery life is absolute horrid right now, and I tried everything.
I tried out different roms, every radio, deleting programs, hard resetting tons of times. I even bought a new 1500 mAh battery but it was still crap.
Battery log says my device in standby mode with the screen turned of uses -70ma, when I turn my screen up it jumps to -320ma, and when idle on the screen for a few sec it goes to -200 ma, but when I browse through stuff again it goes to 3xxma again. When I surf on the internet it picks up to 450-500ma.
Now, this morning with the 1500 mAh battery fully charged I played a few games of XTRAKT, few texts, 1 hour of music listening and 10 minutes of being on Opera through a HSDPA connection. It was down to 45%.
This isn't the normal rate the battery goes down at right?
I use HDtweak to manage my connection and put it off after a minute so it isn't that I keep dataconnections open. I never use bluetooth or wifi either.
Could it possibly be that it's the charger of the device? I perhaps have the feeling that it doesn't put enough juice into the battery even though the green light led goes on to indicate it's full.
Some feedback would be much appreciated cause it's put me on the edge of selling my device, which would be a shame cause I'm really fond of it (except the battery ofcourse ).
Thanks in advance!
/a
P.s. I am from a pda background, so it isn't that I'm expecting too much of the device or comparing it to a normal cell.
May I ask what you searched, as there are 3 or 4 active threads on battery drain right now?
Hi
Had same problem.
Try to browse a storage card if its very slow You must format it and it will back to normal.
very strange but its working.

General battery drain yes, not the possible issue of a charger though. If I'm wrong I stand corrected. .

Hi Antrak,
Touch HD has the longest battery life of any similar 'phone. See e.g.
http://www.pcauthority.com.au/News/1...-the-rest.aspx.
Either your battery is not charging correctly, as you say (try it via the PC USB cord?), or you have two dud batteries in a row (very unlikely) or you have a bug in your m/board. 70mA in standby is too high. It should be <20mA with only the 'phone on in standby mode, providing you are not moving from one cell to another all the time, and have decent signal.
One other suggestion. Drain the battery completely to zero, then recharge it to max. This should reset the internal battery meter. But don't do this too often, as it ages the battery faster.
If none of these work, return the 'phone for a m/board replacement undere guarantee.
I have the same problem... After charging for 10 hours, my batt shows 55% only.. and last 1hr on STANDbY!!!
IMAGINE! charge for 10hrs juz to get to use for 1 hr.. im disappointed by the batt.. im not sure if HTC is gona let me exchange with a new one or do I have to buy a new batt..
try check your sync..its active all the time or not..
if yes..
find the threat to make a fake account for sync, so you can active it manually.
so your battery will stand more longer,
about charging..
me also facing the same problem..
need to change it more longer to get full battery,
but
if i change in my car,
no issue
very fast
i thing charger issue..
but i bought original set..
??????????????????
Okay I've charged my HD through my pc with a USB cable and formatted my SD card like a other user said. Gonna see how it holds out today. It could very well be that some chargers have issues.
My experience with the Touch HD says that when charged with a USB attached to a computer the battery life is a lot shorter than charged through a wall socket.

This is always going to be the case. Quickest way to charge your device will always be through your wall socket and with your device turned off!!
Same battery issue.
i recently purchased a new touch HD (T8285 telstra version) and am experiencing the same horrible battery issues. it takes more time to charge it, than i get use out of it.
i've tried multiple batteries, and am in the process of trying different ROMs.

Indeed, here's an illustration...
Image1:
Charging via USB takes longer. Consumption and therefore charge current is erratic after the battery level reaches 50% when charging via USB on my HD. So the battery fills up to about 60% of its capacity by the time when the battery level is reported to be 100% and charging stops.
Image2:
When charging with an AC adapter this is not happening and the capacity is fully utilized. This is also quicker.

That's strange. For me it's quicker if the device is turned on. When it's off it takes around 8-10 hours to charge but when it's on it's alot quicker.

hmmm, I don't know how this is possible?
If your device is on there is always power outage especially with programmes running, whilst if your device is off, there is no power drainage so device should charge quicker.
What rom are you using? software installed?

Latest official rom with alot of software installed. But it doens't make sence to me either. It's logical for something to charge faster when it's using no power (off) then when it is using power (on).
Combine battery threads ???
Hi to Moderators,
There are now several threads on the HD forum on battery and charging issues.
Can these be combined into one place and stickied, so we can get a clear picture?
Current threads are this one, plus:

I have a gut feeling from what I'm reading, that HTC have had a bad batch of batteries or charger circuits in the HD - in which case the best starting point is to call their service points and ask for help/replacement, instead of spending lots of time on other remedies. The symptoms described have lots of commonalities, and the HD is normally an excellent beastie for battery usage.
Thanks for all your help, ladies and gents! Your work is much appreciated.

Heya,
Don't know what it is but my battery life increased a tad. Am running Dutty's X3.0 with the 1.32.x.x. radio. Watching a 1 hour xvid dvd rip (no conversion) in coreplayer on full backlight with no HSDPA on, wifi or bluetooth takes away 20% of my battery, which is acceptable.
Don't think it's the SD card format though, it might be that I never have the activesync process on anymore by setting it to manual update and closing it (it otherwise keeps running.)
/a
Does anyone have any suggestions on what I can do to test which one might be bad? Any app you know of that can monitor things and tell me if a rogue app is killing the battery or if the battery is bad?
I was running mik 1.1 and was using it pretty heavily with gaming and downloading stuff. The phone died after about 7 hours. I thought that maybe the rom or cwm or something else might be killing the battery. Something strange though is that, like I said, I ran the battery until the phone shut off. Then I left it off and put it in a wall wart charger for about 8 hours and the status light was still orange. My gf had the phone and told me once she left it plugged in overnight and in the morning it was only at like 50 something percent. I thought maybe the charger went bad so I gave her another one and she didn't say anything else about it. I'm starting to wonder if maybe the phone's battery has a weak or bad cell. I kinda doubt that there's something wrong with the charging circuitry of the phone but there could be, anything is possible. I will probably take it to the repair center and tell them about it and see what they say. I tried looking on htc's site for oem replacement batteries but couldn't find anything. I found lots of aftermarket but I didn't want to go that route.
I don't know if it would not be a good idea or not to try and use my original evo battery just flipped over. I suppose if that's the only thing I have to try and troubleshoot this problem then it will have to do.
Can anyone give me suggestions or has something similar happened to you?
Now let me see if I can find that evo battery..........
Spare parts, in the market if not on your rom by default, had a battery information tab that will indicate battery health as well as what kind of plug the phone detects when charging (usb, ac, or none)

Like danaff37 said, spare parts can be useful. Also try CPU Spy, free from the market, which shows what % of the time your CPU spends at each frequency, but this actually more relevant for determining if your phone is properly sleeping..
For proper charging you can get an app like CurrentWidget or Battery Monitor Widget which tells your the current consumed during usage or current injected during charging, as well as the voltage in mV. Full charge should reach around 4200 mV, and when charging the current should be around ~800 mA for lower % battery left.
Thanks for your input. I found the evo battery and did the same thing as before. I ran it until the phone shut off and then put it one the (same) charger and went to bed. About seven hours later, it was still orange charging. Both times the phone was off. Now something that could be a possibility is the charger is weak or bad. When I put my evo on it, it charges seemingly fine. I should try using the battery until it shuts off again and use a different charger and see what happens. Six to eight hours charging, with the phone off, coming from a dead battery, on a Motorola charger that has a rated output of eight hundred milliamps at five volts. I have others at different output rates and a two amp charger intended for an ipad. Some might say that the charger is too much for the phone. The charging circuitry only pulls as much amperage from the charger as the phone was designed to. Now on the other hand if I put a smaller output charger on, say one hundred and fifty milliamps, it will take longer to charge the phone than usual. "They" say trickle charging is better. Whatever. I will post my results if I find any. Or, I just might trade the phone in for a nexus s or an evo 3d.
I was just about ready to throw in the towel and say the phone was defective, but then things started happening. I will fill you in on what I have done in the meantime. Okay so the flipped over evo battery kinda works but not completely. It will charge but not to 100% and green light. To test this, I took the evo battery out of the shift. It didn't seem to want to go more than 98 or 99%. I put the battery into the evo and after a few minutes the light went green. This was initially off. Then I booted the evo and let it go to sleep. After it booted the light went orange then green after a few minutes. Okay so the evo battery is capable of going to 100%. These charging tests were done with a different charger.
I forgot to tell you, I let the evo battery charge while I was at work and the phone was off. So the battery was charging roughly twenty hours and still no green light. I suspect that even though the positive and negative terminals aligned with the correct tabs on the shift, the center two contacts must be different internally than the shift battery. I speculate that those center tabs are for the battery and phone to communicate to each other during it's charging state. I am guessing that the battery tells the phone it is fully charged and to go trickle charge and perhaps the evo battery wasn't communicating to the phone or the phone didn't know when to say it is done charging. The battery never got hot either.
The shift was rooted, running mikshift 1.1 and the latest clockworkmod recovery. Here is where I suspect that there still might be charging bugs with that setup. I used the pcxx.zip file that when booting into the bootloader, would flash the phone back to stock everything. After trying this and assuming that the phone was back to stock, I kept going with my what the hell is going on with this phone battery charging test. A note about the flipped evo battery. Yes it will work in a pinch but it won't charge properly. Luck has it that the notches in the battery and phone allow it to work in a shift. Only thing is, the shift battery won't work in the evo. The tabs are on the wrong side and the phone's tabs won't allow the contacts on the battery to meet up with the phone's terminals.
Okay, where was I? Trying different chargers wouldn't make the shift green light full charge. I tried the same chargers on the evo with it's original battery in and it would green light after a few minutes on or off. There wasn't anything wrong with the chargers. Oh and another note, while using the battery monitor widget, I noticed that both phones wouldn't pull more than a little over three hundred milliamps of power from the charger to the battery. Interesting to know how much it really pulls from the charger.
Anywho, I tried something different for my process of elimination testing. I actually ruu flashed the shift back to factory and guess what happened..... The battery and phone were charging both on and off all the way to green full charge at 100%! I think I'm getting somewhere with this! All my luck, either it is a known bug somewhere in the forum in a place I haven't stumbled across or I'm the only one that this is happening to. It doesn't really matter I guess.
My conclusion, which isn't scientific by any stretch of the imagination, is that the phone isn't truely back to factory unless you ruu it. The pcxximg.zip doesn't put everything back to stock. I haven't narrowed it down to what is causing this behavior. I don't think it is root. It could be cwm recovery or the rom or both. I didn't try the stock rooted zip either. I suppose I could go further with this investigation but I am too lazy to now. I might root it again and just leave things stock rooted. I might activate this phone in the morning and run it all day tomorrow and see how it acts. I will have to charge it a few times during the day to keep the levels up when I really use the phone heavily. I've written enough for now. Does anyone have anything to ask or add to this topic?
Since the latest update to CWM phone-off charging finally works again but the light never turns green. It charges fully but with the phone off the LED never turns green. It's not just you.

OK. I thought something might have been broken.
Forgive me, I am truly a newbie to Android after having a BB for 8 years. This battery thing is killing me. I am on my 2nd Evo Shift, the 1st one wouldn't last for more than 2 hours with barely any usage so they gave me a new one. This one barely lasts 5 hours. I am barely running anything. I took it into the store and they thought I was going to be running all these programs, but I kill everything. They told me the "battery trick" about turning off the phone and unplugging it and plugging it back in 10 times so I did that but I am not getting any more life out of the battery. My display is constantly using at least 70% of the battery it says even if I turn it down very low or if I set it to choose its setting. Do you have any advice for me? I am not running a task killer, I kill all the programs I am not using. I have no widgets running because I am afraid to use the battery, I only have 2 screens out of the 7 with things on them. I am being help hostage by my cool phone that I want to use but am scared to kill the battery! (sorry for the long post)
Ok if you use a lot apps just close them after (for stock 2.2) . Even on stock you can literally stream music and movies for about 4-6 hours. (sometimes a lot more) . The background info that runs doesn't use a lot of juice , but if you want you can go to your home screen any of them hit menu (but not with the app drawer open) select settings go to accounts and sync turn off background info and just turn it on manually when needed such as the android market . You can also turn off the auto sync and just manually choose to sync , like in the clock (and gmail etc.) it will say no weather after you click it , just hit menu you will see a little sync button option to sync and voila you have weather . So when you visit the market it will automatically ask you to turn it on (background info as will all apps that need this) . And the screen on any android is a battery killer . So when not using your phone simply tapp your power button to turn your screen off and lock (and to keep from pocket dialing lol) . But if all you do is text , emails , and web surfing (surfing drains more but no where near as much as streaming) you can literally do that all day , the screen will actually suck the most power . If manually turning off your apps is too much . Just turn your phone off (not just the screen) and on . If a new app didn't turn off after you start your phone back up you know that will be a problem later . So when not using your phone turn off your screen it will last soooo much longer . I only make a call or two and a couple of texts maybe a few minutes of internet with opera mini . My battery lasts over 24 hrs , but I barely use my phone . Hope that helps .

BTW if you have a bunch of apps running in the background video games etc ... and you charge your phone all night and in the morning it is not charged . You should probably turn your apps off . Or simply power your phone off which shuts off most apps . Then turn it back on . The phone should not take all night to charge , it should only take an hour or 2 . 3 hours max .

i suggest watchdog lite,it monitors cpu usage and alerts you when 1 uses more than your max threshold.if this helps,please click thanks.
When you changed ROMs, did you do it with a full charge? If not, your battery stats file is probably messed up.. Ive used Battery Calibrator free from the market in the past to fix that problem.. I believe a brand new battery on the Shift shows about 4200mV when fully charged or just slightly below that.. Run the app, when it gets close, calibrate (which essentially just deletes the battery stats file and creates a new one)
Ever since I had gotten my Nexus One back in July 2011, I had been really pleased by the battery life. With my usage patterns, I could easily get two days on a charge, sometimes getting three comfortably. All of the sudden, about half a week ago, I noticed that the battery would discharge itself really quickly. It would go from 100% to around 30% in a day. I hadn't changed my usage patterns, nor had I installed any new apps. I went into the settings for any apps that may be loading data in the background (Twitter, Facebook, News/Weather, etc) and made sure background data was enabled, and I always turn off mobile networks (EDGE/3G) and WiFi when I'm not using them. I even went as far as wiping the phone and resetting everything, but no change in battery life. Calibrating the battery by letting it fully discharge and then charging it fully while the phone is powered off also did nothing. I'm at a total loss here. This seems inexplicable as to why the battery life is now so bad.
i change my battery every 6-8 months batteries are stupid like that i had this problem also like 5 months ago i just bought a new battery then BINGO 3-4 days on 1 full charge with every know battery tweaks if you look for battery look in the Nexus Q&A thread someone asked whats the best battery life ... hope i helped

Thanks. I think I'll order a new battery, probably a standard 1400mAh battery instead of one of the larger-capacity extended batteries. I don't really want to add any more weight or thickness to my phone. If that doesn't seem to do the trick, I'll probably just eventually buy a new phone. I've been looking for something different for a while now and this will give me a good excuse to do so. Heh.
I don't want to jinx myself here, but I may have found a temporary solution. Use only 2G networks. Curiously, about two or three weeks ago, I noticed that the mobile network type has changed from HSPA to HSDPA. AT&T appears to have done some upgrades to bring "4G" to the area. I wonder if the changeover has done something to my Nexus One and now was drawing more power from the device searching for a signal? Ever since I've disabled 3G, I've been on EDGE and I've only lost ~5% battery compared to the near 25% that I had lost on HSDPA. I'll check back if I find out anymore information.
One option is to try to recalibrate the battery. There is a root app out there that allows / guides you how to do this. Just search battery calibration. Additionally, instead of using an app, what you can do is boot into a custom recovery image (preferably 4EXT touch) and wipe the 'battery stats'. Then turn the device off, charge til the LED is green and then leave on the charge for an hour after it turns green (maybe overnight?). Then run the battery full out the next day to properly calibrate it.
Yes, 2G mode only does save a lot of battery. Apps that sync in the background (IE Gmail, FB, Twitter) use battery a lot. From your post it sounded like you have them set to auto update. Disable that or force it to refresh less often. What is sounds like is that your device maybe trying to connect to cell towers but is having a harder time; this may be due to ATT's 'upgrade'. I'm not too sure about that stuff though, haha.
Just as I had expected, I believe that it is an AT&T-related issue. A friend of mine who has an Aria has been experiencing the exact same battery drain issue that I had been having.
recalibrate your battery
1.drain your battery until you get the message "powering off"
2.quickly connect your charger
3.charge it 8 hours straight..
Battery calliberated...well it worked for me...:thumbup:

Solution
I had the exact same problem. I had a refurbished nexus one, everything was working fine for a month then suddenly one day battery life goes from 14-16 hours to 4-6. I call customer service and search online, do all the battery pull out replace and whatever but no result. Took it to a shop, they couldn't figure out how to fix it but mentioned perhaps I should change the power strip (the black plastic card wich has the power button, camera and flash attached to it). Look at ifixit nexus one teardown for the actual part. So I bought a new power strip, replaced it and my nexus one is back to its original 12-14 hours. Not sure if this will help you, but that's what I did to fix mine.
