My N1 eats battery like mad. Lost 30% in 2.5 hours with light usage: no calls, no wifi, gps or data. Just reading a document on the phone
I searched and tried this: drain battery completely, charge phone when switched for 8 hours straight but still the same :/
This is with stock Rom and the many of the custom Roms
The phone eats a lot of power trying to connect to a cell tower if the signal in your area is weak.
Mine was doing this and changing the network to GSM (prl) did the trick.
Is your area bad in coverage?

no the area is fine, London Area. Please explain the prl trick
yea mine eats crazy bad, but i always have gps/data running and decent amount of txting
and apps that use and stay running on the Background kill battery too (Tikl)
The answer is froyo with exchange mail pushing. There is a problem with the way it obtains/verifies SSL certs and it cycles the CPU endlessly. It makes the phone get crazy hot and eats the battery. I've had to completely disable exchange email to use my phone with 2.2.

Links are not against the rules, you will be allowed to post links once you have more posts, it is XDA's effort against spam and it works pretty well.
Back to the topic, it is possible that your battery meter is not updating properly. It may say you have 30% but then suddenly you drop down a lot.
Also, first try charging your phone all the way, let it charge for an additional 10 minutes after it says it is fully charged and then wipe battery stats and see how that goes. Wiping the stats will delete the files that are related to battery stats, it is useful when you are trying to recalibrate your battery if for example it says you have 9% and then it just shuts off.

Draining should not really matter, it is not like the old style batteries. Someone may disagree with me though. Why eight hours? And it shouldn't matter if it is on or off. If it is on and you look and it says fully charged, leave it for another half and hour at least. Then wipe battery stats and see what happens.
i did let the battery go at 4% once then wipe batter stats but no luck
My battery is still draining insanely
I followed this guide http://www.villainrom.co.uk/vBwiki/index.php?title=Calibrate_Battery a few months ago and yesterday but no change!!!!
Reading documents drains a lot of power, having white all over the power-hungry screen for a long time.
3 hours, 25% - nothing unusual.

That's a bad guide, letting the battery drain completely flat is one of the worst things you can do to a lithium ion battery. It kills off the capacity.
Charge battery full (prob only take 2 hours), turn off phone charge another half hour. Still plugged in boot into recovery, wipe battery stats.
These batteries have no memory effect, so draining battery does nothing

My battery life increased after upgrading to gingerbread. I can usually go through the day (15 hours) with 3g always on, twitter and fb sync on, with light gaming and surfing of the web, 75% brightness.
My record was 2 days 9 hours with 0% brightness, no 3g, only wifi, no gaming, twitter and fb sync on.
For your percentage problem, you can try draining your battery, then when the phone shuts down, hold the power button to switch it on again. Start up an intensive app like a game to further drain the power. Do this until the phone does not start up (no bootscreen), then plug into the charger and charge overnight. DO NOT turn the phone on during the charge. When you turn on your phone after the overnight charge, it should read 100%
I am not too sure what triggers this, but its likely due to battery memory or something, although this should not be happening for lithium batteries. Maybe its a software fault. Do this every month or so to hit that 100% indicator. It is not advisable to do this all the time as draining the battery completely MAY damage the battery over time. Cheers!
How did you manage to get pass 2days of usage?

Hey,
I'm also having the same issue. Off the charger, BANG! 96% or so, sometimes more. My phone will be at 90% after like 3 texts. Its only had 5 charges mind you, I know there's a "conditioning" time but still, is this normal? I can almost say a text is a percent...my 3gs had more batt life after 1yr... now that's saying something...haha
I can almost watch it drain with the screen on...like 60 secs is a percent or 2...not cool...
Maybe I can do the "Desire Battery Calibration" procedure after a few more full charges...might make a diff...what do you guys think? I may be jumping the gun here...
Thanks in advance.
I remember someone said modern phones are designed not to keep on charging after reaching 100% and resume only after dropping to certain level, maybe 9x%. That could be the reason why I see different percentage left every day I unplug the phone in the morning. But my last Hero always show 100%.

That sounds right, because it drops from 100% to 96% after a few seconds, and its direct from 100 to 96.
But if you put the charger back it taks a couple of minuts to get from 96% to 99% and about 10 minuts to go from 99% to 100%
As far as i have noticed, this was the issue with X100 too after 2.1 update-
Once connected to the wall socket, the phone charges to 100% and starts dropping.
it does not charge again unless you reconnect the charger.
till the time it is connected, it will display as 100% but once you remove it drops to how much ever time has been spent since it reached 100%.
why that happens, i really don't know.
Ideally the phone should continue charging if the level is below 100. anyways....
about the battery backup, i think 13-15 hours is quite good for a phone with this display and capabilities.
with 3g, a little gaming, surfing, chatting etc. this should really do.
in fact, post the 2.3.3 update, the battery life has definitely increased.

So you think that having a 13hrs ++ battery life is good enough?More advice please..thanks..
Sent from my HTC Incredible S using XDA Premium App
I am on a VzW Inc2 w/ Froyo so not sure how applicable any of this is for you guys...but anyway....
My battery life is fantastic. I too see the 100% down to whatever after unplugging - I am pretty sure this is like others have said; once it reaches 100% during charging it stops charging and does not start again until you unplug and it re-plug it in. I know in my case charging from dead to 100% only takes like 3 or 4 hours. So if you are plugging your phone in when you go to bed it is probably hitting 100% after 3-4 hours and then the rest of the night it is draining down...
I have found JuiceDefender Ultimate and JuicePlotter to be huge helps to me in decreasing battery drain (JD) and understanding what uses the battery (JP).
Also just going into settings, About Phone, Battery, Battery use - this helps understand what is using it.
*Note: JuiceDefender Ultimate can create more problems than good if you are not willing to take the time to learn/set it up.
Prior to using JD and JP I would generally make it through the day, sometimes have a bit of power left over. After using these I always make it through the day, and sometimes through 2 days.
But let's not kid anyone - what JD does you CAN do manually...but more than likely wont or will forget. So for anyone that doesnt want to use JD, do you leave your WiFi on all the time, or do you switch it on/off? Leaving it on all the time drains battery. When WiFi is available, do you use it? I have found WiFi on this phone to use a lot less battery than 3G.
Probably my favorite function of JD I have it disable 3G and WiFi when the screen is off (for getting emails, updates, etc... you can set a schedule where it turns it back on during intervals or whatever).
Also I like the WiFi Location setting - you can teach it where you use WiFi and it will automatically turn WiFi on/off based on your location.
Anyway - my guess is if you are having low battery life, either you are using the device a lot more than you think (voice calls use a lot of battery), you have things syncing too often, or you are leaving radios/etc... on all the time that do not need to be on.
I tried to take the charger out at the same time the battery was on 100% and the LCD light went green.
Then the battery stayed at 100% for about 11 minuts and then went down to 99%.
After 3 1/2 houres the battery is at 95%!!!!!!!!
Bagground Data is enabled.
3G is active.
I have mail check every 15 minuts.
Screen brightnes at 40%
Weather update every 1 houre.
I don't use Facebook, Twitter, Stcoks and News.
I don't understand the battery in my IncS...
You guys know that these batteries don't have memory right? So when you charge doesn't matter, your phone just thinks there is that percentage of battery, do a full drain once and then it should back on track. Also, these batteries never get charged to 100%, its a safety precaution or something of that sort. They hover around 94-96% which is why the phone drops down to that area in what seems like a short amount of time. The fact that the phone says 100% when you unplug it is for effect. I used to always think I had battery problems, just stop being so worried about the battery and you'll notice an improvement. Hope this helped.

Also draining them completely flat, as in device won't power on, is the worst thing you can do to them
It sort of kills off a little of the capacity, every time you do it
So to the bloke that recommended it, no it does more damage than good

Still cant find a widget that will do it for me...not mobile data, ACTUAL WCDMA-GSM and back...

I tell you is true, and i don't understand i either!!!
Most of the 17 houres the phone was only in standby and i only read mail twice.
I guess its just a fantastic ROM that Mike1986 has made with no Sense ;-)
I can get a day and a half out of my IncS with heavy use on a pretty regular basis. Set brightness to automatic, switch off unnecessary auto updates, GPS, bluetooth, and keep volume down or off in games. My screen timeout is 1 min (reduce for longer battery life), and I have always on internet switched off. I generally leave my Wi-Fi on a lot by mistake but don't find this to affect things too much really.
You will get 96% a lot after a charge as it is bad for your battery to stay plugged in when it's fully charged, so the s/w on HTC phone switch the charge off for a little while so it runs down a little and back up again. I had Hero before and that did this as well.
juice defender ultimate is excellent in my experience.
i had it set to switch on data every 5mins for 15secs to receive notifications and do updates (i have quite lot syncing - twitter, fb, sky news widgets x2, weather) and i would sometimes have gotten 30 hours out of the phone (ie. i wouldnt have charged it 2 nights in a row sometimes), but always easily 1 full day.
im getting sick of having to use JD though, because i figured something HAD to be wrong as my battery would drain in maybe 5-8 hours without JD which I just dont think is good enough and so could not be how its meant to be.
i then read about some people having problems with cyanogen rom battery drain, and that if you switch off android market notifications, it solves it.
so i tried it, charged my phone to 99% again and im now at 82% after 5 hours 10mins, which means if i keep using the phone at this rate, ill make it 25 hours - which is more than good enough for me. (~and i still have all the same stuff syncing as before, except market notifications~)
also i have wifi set to never sleep, so its always on. (its my ideal that everything that you buy the phone for should be able to be kept on 24/7, eg data, gps etc always on - so i keep them like that. bluetooth i dont use though - if i can make it through the day on a charge with decent use, im happy)
try it.
im calling BS on jkolner btw - pics or it didnt happen

Recalibrate your battery. Thats what helped me. my device can last 9 hours and still remain 70% battery with normal usage.
Heres how i callibrate.
1) download battery callibration in market.
2) charge the device till 100% (Dont plug it out)
3) power off the phone. I dont know if this will work on ur phone but i get 0% again. So charge it fully again.
4) once it shows 100% , unplug and plug it in again and wait till it reaches 100%. Do it for 4-5 times then reboot.
5) when your phone boots up, it wont be fully charged, so leave it charged till the battery full indicator shows up. Unplug and plug it in to charge again. Keep doing it for 10 times and the battery full indicator will pop up even quickier then the first time.
6) once u done it, open battery callibration and click callibrate.
7) after that, unplug your device and use it . The battery will last very long.
8) use the battery till 1-5%, u can completely drain it but i didnt do that cause some of my data will be removed after i completely drain my device.
9) charge it up to 100% again but dont use it while charging.
10) after that, enjoy ur battery life

I've got a doubt about battery discharging in my phone. When it normally discharges from 100 to 35% everything is in normal, with similar drops every hour for ex. 2 days. But (even in standby) when battery is on app 35% I see very fast drop to 25-20% in couple mins. At the beggining I thought it is maybe broken cell in battery but I notice that around camera surface is warm, not hot. So it is probably matter of software. What drains my battery so fast and always at app 35-30%? Do you have similar issues? I made factory wipe few charging cycles ago but it did not make any changes.
Do you use any of the power management settings like stamina more or....
What apps do you have installed?
Sent from my C6603 using xda premium
Yes, I always use stamina, I switched it off just before taking picture. I use dropbox, GO backup, Network Singal Info, netmonitor, Gmail and one additional mailbox. I have Google backup - off, Hangouty - logged off, google now - off.
Well, I don't use stamina mode anymore. I too had these sudden drops when stamina mode was on.
Try switching off stamina for a couple of cycles.
If you find that there are no drops, then you have your culprit.
So you mean not use stamina at all or switch it off at around app. 50%?
Try without stamina mode.

Deleting battery stats does nothing. I post this every time I see someone recommend it, but I feel that the point needs driving home until people realise that it is a placebo at best.

No. The batterystats.bin file has no relation to the percentage displayed in the notification bar. It is used to calculate the usage statistics displayed in the battery usage section of settings. Nothing more. The file is deleted every time the battery is fully or nearly fully charged anyway.

I am sure that I hadn't wrong percentages but period of strange drain battery (when % suddenly drops) because I felt warm temperature around camera. So I suspect any strange thread/wakelock/trigger.
I've tried to fix this on my own, to no avail. Whenever my phone gets down to 50% battery life or so, it shuts off. Then, when I charge, it says 0% and will charge up to 100%, then shut down at 50%. It'll shut off around 30% occasionally. I've tried different ROMs- currently on Rapture 3.1. I've tried various battery reset programs- nothing has helped. What now?

Definitely a bad battery. I use Anker batteries and they works great. You can buy Anker battery set for around $20 on amazon.
I purchased a new battery (Samsung oem)- received it today, and put it in. Charged it to full, used it a bit, and at around 50%, my phone shut off. Any other ideas?

Though it's highly unlikely, but did you make sure that you didn't put old battery in your phone instead of new one ?
Battery Cal seems to have solved it, and is also obvious when I think about it.
