hi i just recently upgraded to the modaco froyo rom. every time my battery percentage hits 20% the phone dies like its at zero thus making 20% unusable. ive wiped the phone, cache, and the battery stats. ive also drained it from 100-20 multiple times to recalibrate the sensors. any ideas?

call HTC and tell them you have a broken battery if you truly have performed all of these steps. You can try manually removing the battery stats first though. I forget where the file is or where it's located but you can search around, I'm sure you will find it.
The thing is I've been using the phone for a while and it just statlrted happening

ive noticed this at 15% thought it was a one time fluke (flashed a new intersect raven kernel yesterday before work) then it happened today i was going to flash back to the default froyo kernal and see if that did it but now im worried my battery might be screwed

Did this happen before you upgraded to Froyo?
Did you update the radio a long with froyo?

I noticed that too when I intentionally let it run down to 15%, seems like its a fail-safe if you will of the phone to limit damage to either the phone itself or maybe the battery. I'm just guessing, but its not something wrong with the rom, it seems thats the cutoff point, I could be wrong though...

Yep, i have 2 ideas:
1) Read the forum rules
2) Post questions under Nexus One Q&A instead of Android Development.

Effective Fix
Hey All,
I recently had the same issue with my S4 and I came across a very cheap but effective fix. There is an app on the play store called "Real Battery" that scales your battery level down to the percentage it dies it. My phone kept dying at 30% so I set the indicator to 30% and it scaled my battery level so that 30% is my new 0%. It lets you know more accurately when your phone is about to die, so that you won't be fooled when your phone says it has charge. Check it out, its called Real Battery.
The thing is, that I'm having this issue for a while now. Battery drains extremely fast both on stock, stock + ext4, cyanogenmod, no matter what. Now I decided to install the stable version of Darky 10.1, but it's just about the same... It's like it drops 2-3% percentages in couple of mins (~10m). I'm using my phone at minimum brightness (btw, display uses 9%! only of the battery), no OC/UV, no animations, only 2g, no wifi, no gps, no account sync, so I'm like really trying to get more...
Okay, and here comes the thing: It used up 70% of the battery in less than 5 hours, and the battery stats looks like this:
Android OS 62%
Android system 10%
Display 9%
Cell standby 5%
Phone idle 2%
Dialer 1%
Dead Rider (just a game..) 1%
In my opinion, everything looks great, but the Android OS. Now what the *** is that, that this crap uses 62% and growing ?! PLease help, thanks!

Hmmm what apps r u using ? how many apps do u have installed ?
Did u buy ur phone used or from new and if u got it from new did u do the over charging for 16 hours or more ?
android OS is a huge problem for battery drain with a few causes and plenty unknown.
to fix it completely will require some skill full people from a closed source.. Download an app such as juice plotter or similar to find out a cause of the battery drain.
there are things you can do such as undervolting for extra battery life.
But the best thing to do is type in Android OS battery drain, in the search bar and have a good read up. i had this mega battery drain a few weeks back but i have it under control now

Charge your phone till it reads 100%, reboot into recovery and I think in Darky's Kernel under advanced you will see wipe battery, do this, boot your phone and let it charge back to 100%, then unplug your phone, let it die to 0 and charge again.....something weird is happening because it shouldn't be that bad....if the above doesn't work and you can rule out apps possibly you have a bad battery?? To rule out apps, wipe everything and do a fresh install of a stock ROM if it still drops then i would say it's a bad battery, but try what I suggested first (wipe battery stats)
The last maps upgrade causes bettery drain....
how to slove this problem?
Hi!
I have the exact same Problem..some say this is a bug in the gingerbread versions and can only be solved by samsung...is this true? Any ideas?
Well, I've had a pretty big read-up on it, and tested it myself, what's more tried out other things too. So I came to a conclusion, that this is absolutely true. It's said to be enough the 'freeze' the apps that cause this problem, but it's just not true. With frozen, they somehow still did it. So here's what I've done, and it looks like solved (far not as good battery life as 2.2.1, but still, at least acceptable...):
- format internal sd card
- removed the suspicious apps (msyncml, syncml, it depends on your rom, the important is, that it has "sync" it its name, and NOT account sync!)(I also removed Samsung account, and everything **** that I didn't need)
I'm having BUJV9 on right now with newest FuguMod and it looks good.
It does not mean Android OS is using 62% of your battery over the time in question .
Its a measure of what has used the power not the power drain on the battery .
Though useful on a heavy drain as your figures show display off OS using a lot but what time span at the top of your figures ..
I would guess from figures posted you have something working away in the background . A factory reset usually cures that problem .
Or find the culprit .
PowerTutor from the market may help .

I was having the Same Problems with Battery Drain. (Dropped 70% in 6 Hrs.)
It is related to 2 Services on Gingerbread.
Software Update & Samsung Account.
Clear Data and Freeze Programs using Titanium Backup and Your Battery should be back to Normal.
Huge drain on battery SGS i9000 android gingerbread v.2.3.3
I did like some other users have done I quess!?!
I upgraded via KIES from earlier version of android. After upgrade I did a reset to factory settings, but didn't set the "Format USB storage".
I installed a few programs and used the phone for a few days. After short time of usage I noticed that the battery drained really fast. Like 20% within 1 hour or so. Normally 20% battery drainage happens in a day with little use.
Then I thought something must have gone wrong with the last upgrade. Many time the tip is to clear the phone again and this time I set the "Format USB storage". It worked. Now the battery drains about 30 percent during a normal day with little use.
Since I have a backup of everything, I just installed the backup so the phone is back to normal again.
I hope this might lead to solving battery drainage issue for other users or at least and idea of what could be wrong.
First of all, I do not trust this solution, but it work to me
Solution is simple, remove your memory card from the phone
That is all
After check, found that the scan media always running to scan the memory card
This might deal to corrupted card
People say backup the data from memory card, format the card, put back the data
I haven't try format the card
But after my phone remove the card, now already 13 hours, I still have 82% and I did few phone call as well
there is an app by the name of battery calibration...follow instruction from within the app and it should solve the problem of android OS drain .. i shifted from darky 10.1 to MIUI 7.7 and 100% to 30% in 3 hours with normal usage and no wifi .. after this app battery lasted for two complete days ... so try it
There is another MORE SERIOUS BUG in ALL GB ROMs:
http://forum.xda-developers.com/showthread.php?t=1134741
After full charge in GB, phone start using batteries ONLY instead of CHARGER ONLY like in Froyo and lower version builds.
Samsung folks goofed up BIG TIME by making phone use batteries instead of charger after full charge while stopping the charge cycle. Because of this OS thinks its running on CHARGER (or USB POWER) and shows batteries as full charge when in reality it runs on batteries after full charge and will eventually make the phone dead through full discharge of batteries.
You could test this by keeping the phone connected to the charger after full charge for a prolong period. When you disconnect, based on the usage during that time, the batteries will instantly show lower charge than around 100% (could be close to 0% as well depending on usage after full charge if you disconnect charger before phone going dead at 100% drain).
Did you flashed Darky in 100% battery? The tutorial suggest you to do that. You can try to wipe battery in recovery mode.
I recently upgraded from Froyo 2.2 to Gingerbread 2.3.4 and now the battery life is absolutely terrible.
Before upgrading, I would get at least 2 days of battery on Froyo. Now, on 2.3.4 a 100% charge leaves me with only 40% charge overnight.
I'm not running any background apps, I turn off Wi-Fi/Bluetooth and so on. I also turned on Airplane Mode to disable network connections.When checking the battery information, cell standby used 29% and phone idle used 71%.
I did some research, and some have related the problem to the battery forgetting it's charge level due to the OS upgrade. A solution is to factory reset the phone and run the phone until completely dead, and charge it overnight for 6+ hours or longer (imagining the phone is brand new again).
What are your thoughts on this?
What ROM are you using? ZEUS has great battery life
Sent from my LG-P970 using XDA
V20b, I updated using the LG Software Update Tool.
A system restore would not be necessary if you are rooteded, just a simple battery calibration. You can get the app on Google Play.
It will delete the batterystats.bin file that was created on your Froyo ROM and generate a new one one the Gingerbread ROM.
But then if it has forgotten, the percentage of energy left would be inaccurate thereby showing false results. The stock battery stats function is cr*p so i would suggest using a 3rd party application to monitor battery usage and current.
That would be a better indication of what is eating up your battery.
Found a suitable battery calibration app. However, my device is not rooted. If I do root my device, I lose my existing manufacturers warranty, right? My phone is less than 2 weeks old, contemplating on whether or not I should proceed to do so.
Yes you would lose ur manufactures' warranty although if u were to flash using SmartFlash or KDZU and do a system wipe, your device will be untraceable. They will never know that u rooted and u can just claim that you got advice over the phone to perform a factory reset.
Rooting is definitely worth it. It comes with its perks but also the peace of mind that any errors that you make are reversible via steps above (as long as you don't drop it and break the hardware).
You could try a factory reset if you don't want to root. Just make sure that you are recharged 100% so batterystats.bin will be as correct as possible.
Thanks for the help.
I think I will charge the battery to 100% and perform a factory reset, and hope the battery improves from there.
Will post an update later.
Same Problem
Same here, had awesome battery life on Froyo then updated to Gingerbread (V20A) using the LG updater and my battery life is now terrible. A solution to this problem would be nice. Any easy way to root my phone without having to flash it? Want to put CWM and do a battery swipe.
yes, you can have back your warranty by flashing back stock rom
my advice is to not install battery savers, just install a simple task killer, root the device and install custom roms which have good battery life
i personally use Zeus and the battery is just awesome!
or just calibrate the battery via an app as our friend just said and observe it for some days
(also, factory reset the mobile plz)
then wait for some days as the phone usually calibrates battery after a few re-charges
Update: Battery is back to normal, if not even better!
Test findings: Charged to 100% and left overnight.
13h 57m 50s later, dropped to 93%.
- Phone idle 75%.
- Cell standby 25%.
So about 1% drop every 2 or so hours, about the same as if I was on Froyo 2.2 again.
- Switched off Wi-Fi/Bluetooth/Sync's.
- Switched to 2G instead of 3G.
- Switched on Airplane Mode.
- Used Easy Battery Saver app (Intelligent Power Saving Mode).
Didn't have to root my phone, which means I don't break the warranty. Thanks everyone for the suggestions, especially FunkyGanja.
Yes...as we know the battery calibrates itself after a few recharges
Btw you can flash stock rom and have warranty baack any time

I forgot to mention that I didn't simply just recharge it again, I charged it to 100% and THEN performed a factory reset.
Apparently it has something to do with the "batterystats.bin" file, when I upgraded from Froyo 2.2 to Gingerbread 2.3.4 the battery wasn't fully charged, so GB thought my battery was fully charged at only, say 50% battery, hence why the battery drain so quickly overnight.
I also came across this post, which helped clarify my problem: https://plus.google.com/105051985738280261832/posts/FV3LVtdVxPT

There is already a battery thread here, please continue the discussion there.
Hi all,
I will admit I have flashed the phone about 4 times in the past 2 weeks (different roms) due to other issues but now when the battery indicator shows 40% which is rite it shuts the phone down suddenly and says battery empty even though it still shows 40%!!! I can even plug the charger in and it will charge from 40% not 0. It did not used to do this.
This problem has affected 2 (cyanogen & stock LG!) of the 4 roms I have tried now so its not a rom issue and the phone was fully and properly formatted before flashing the new roms.
Even when booting back up it lasts a minute and does the same. Battery drain is not fast and all works fine until it goes below half.
I have wiped catche, battery stats & Dalvik catche many times when 100% charged but makes no difference.
Baseband is correct also.
I really need help as its unusable having 60% of the battery usable.
Anyone got any ideas before I sell it for parts ??
Thanks

do you have problems with battery before you installed anyone ROM?
and maybe isnt problem in ROM maybe battery making problem
Are you using the kernel that comes with each of the roms or are you using a custom kernel such as pengus' kowalski kernel? I know pengus implemented a new battery driver that has been known to cause other people similar problems.
I flashed CM 10.2 last night, and it had about 80% battery. But in the morning found the phone's battery dead. Recharged it again, and found out that it was losing 10% of charge in 15 minutes on standby. This is the first time I had battery issues like that.
I was using HarshJelly (latest build) , over which I flashed Carbon ROM (Build 6). But the carbon ROM was stuck in a bootloop.
SO, I decided to flash the benevolent CM 10.2. But got the battery issues I just mentioned.
I checked that wifi was off and brightness was at minimum.
AFAIK, kernel might not be the problem as CM installs its own kernel, as told to me by the people here at xda.
Does somebody has a similar problem? How can I stop this?

You did factory reset and you wiped cache and dalvik cache? What was consuming your battery most? BTW CM10.2 is draining battery more than stock and CM10.1 I think.
Yes, the usual drill - factory reset, wipe cache and wipe dalvik. Each of the times I flashed a new ROM.

Discharge/full charge 3-4 times. It should make it more normal... In Battery settings, what is shown to drain most?
The top drainers are-
1. Android System - 21%
2. Android OS - 18%
3. Mediaserver - 16%
4. Apollo - 12% (listened to music for over an hour before last recharge, using headphones of course)

This is first chageing after installation? Probably Mediaserver scan something, after it is done it will not drain that much. Like I told, do 3-4 cycle of discharge/charge. After that you will have better picture about battery life.

I bought another battery and for my surprise I got the same performance. So I investigate and I installed a battery calibration. You must be root for use it. You must charge the phone all the night, and on the morning, you launch the application without unplug the phone to the charger. Once you did it, unplug it, and try!
You must do it after every ROM install.
As shut_down said, the battery pretty much figured itself out after a couple of discharge cycles. Right now, I charge it once every two days! :highfive:

I want to try this too...
It's charging until 100% and then use until 0% then charge again???
Or is charge until 100% then discharge a little and charge again until 100%??

Charge to 100%, discrarge to something about 0% (0-5%). And again charge to 100%.
there isn't such thing as battery calibration. 10.2 is a battery drainer, period

Well i tried this (I discharged my phone completely) and after charging overnight, it feels good...
Still testing...
