Extreme Battery Drain

Hi everybody,
I've read all the threads on the battery problems, but I'm experiencing something different.
My phone is rooted but on stock rom. The last two days, my phone charges to 100% and when I unplug it, it stays there, but then throughout the morning, it drops drastically. yesterday I unplugged it at 5am, by 8:30 I was at 73%. I normally make it a full day 5am-10 at night, the lat couple days I'm lucky to make it to 4pm...
Any ideas or suggestions???

Download and install OSMonitor and see if the init process is continuously using 100% CPU. I've experienced this bug myself.
The current fix is to enable USB Debugging.

Thanks for that, it has been bugging the hell out of me why the CPU has been sat at 100% and the battery has been less than average.
USB Debugging now enabled and the CPU is scaling properly again.

I have 50 apps installed currently

Try wiping battery stats, then let the battery drain to 0% from 100%. Then charge the phone while it's off to 100% and it should be good to go .

Ive had decent battery drain too, Stock rom but Root with Stock kernel with added voodoo. My battery life was worse with CM7, but better just completely stock. I think ill just go all out stock once i get the push for 2.3.3

No problem. It's a very odd bug and I'm hoping 2.3.3 fixes it.. As I notice another bug is introduced when USB Debugging is on .

So yesterday my battery was performing horribly. It died all the way, I then charged it from 0% to 100%. Usually it drops down to 97% right away, but it stayed at 100 , but once again dropped pretty quick. Its 9:30am, I took it off the charger at 5:00am and I'm already at 77% , with barely any use... Is this just me, or if this the norm.

Having applied the 2.3.3 update last night, I turned USB debugging off just to see if the /init process problem was fixed.
I'm happy to report that so far all is well, the CPU is scaling nicely and sitting nice and low when idling.

Reporting the same thing here, haven't noticed the bug reappear. Also loving the nice performance boost as well (1800 Quadrant score on stock 2.3.3!).
But, the colour change not so much .

As I use a colour calibrated monitor on my pc (for photo editing) I'm actually loving the new neutral white balance. I can understand why some peo people are finding it a bit muted though.

You might be able to fix this by reconditioning your battery,otherwise your battery is just getting old

It could not be getting old I just got it last month
Sent from my SGH-T959 using XDA Premium App

Thats how it is.
cm7 and miui have same problems, and its to save you from over charging, and thats some phones start heating up too much.
Don't worry about it, its for your own phones life.

Ok that's good to know and my phone charge extremely slow and sometime not at all but then I reboot and my battery life goes way up wat is that about
Sent from my SGH-T959 using XDA Premium App

Thats because your phone is mis-reading your battery's charges.
a Re-condition would help phone re-read it more accurately, but idk how you'd do that since to re condition you have to charge till' 100% lol.

Will they change rom to make it 100 cuz I don't want to go back to 2.2 rom cm7 is to good

the CM7 your using is not OFFICIAL, so the problems your facing is up to the developer to solve, not the CM team because as far as i know, they haven't even supported CM7 for us fully yet.

it's just how cm7 is reading the battery. on one revision i would get a max of 95% then 97% on another. just recondition the battery after its been plugged in for while after hitting the 97%. worst case is you have to recondition your batter again after you flash another rom or it gets fixed.

Do you know what cm7 version they've used as a base for the vibrant version? The Nexus S does this by default, to protect the battery as others have mentioned.

YOU need to re-condition, YOU can fix it.
the people on MIUI or CM7 can't.

As stated its a known thing.
I used my Samsung Focus to charge a battery to 100 percent put it in my phone and it discharged to 95% then back up 97%. So the phone isnt charging the phone up all the way as it is. This is also good for the life of the battery and the battery will last longer. Also it gives and accurate reading. Sometimes with phones if it says 100 percent it is discharging thus you actually only have <95%.

I fixed the problem I just switched to best rom(trigger) then reconditioned and it charges perfect thanks for the help

This is by design and should occur on all Roms. Below is a link to a good Phandroid article tiled "Your Smartphone's Battery Gauge is Lying to You and its not Such a Bad Thing". It really does an excellent job with a fair amount of data explaining why your battery will only charge to 95 - 97%.
It boils down to three options:
The phone manufacturers essentially have three choices:
1. Use older charging styles which actually maintain a full battery, thereby decreasing its eventual life
2. Use new charging methods and have an accurate battery gauge
3. Use new charging methods and have the inaccurate battery gauge

RECONDITION.
I told you before everytime you flash a different rom, the battery is going to be different, so reconditioning is going to help you make it more accurate reading. brah.

I did I fully charge then wiped then drained recharge then wipe

You may need to do it a few times.
But since you are on a 2.2.1 rom... no need to worry, when it tells you its at 97% it's actually at 100, soon when you don't notice going from 1% to 2% will take more than regular time, it'll make up for the 3% somewhere along the lines

Ok ill let u know the results of this second try and do I have to recharge when phone off

Ugh.. getting mad at battery life!

I have not changed anything... I was getting 16+hours and still having between 15 and 20% left but the last two days I'm hardly getting 10 hours! WTF!
What is a good program for seeing what apps are open when they don't need to be? Would that just be like a tast killer?
Just a little rant... sorry. When I complain to my friends they just call me a nerd... I need to vent to people that understand, haha.

does your ranting require a new thread?

Wow people, how on earth do you guys get battery life of 16hrs. I can hardly get 3 hours on my phone...

Nope.. I use it moderately. listening to music for maybe an hour brings down my battery levels from 90 to 58% and this thing is draining 1% every 2 mins on standby...
Btw while I was charging my phone and it magically jumped from 8 to 34% in jus 10mins or so(I had switched it off before charging and after few mins of charging, I switched it on to find it on 34%). Is this a factor??

that's ridiculous, that must be an application eating up type battery

jumping percentage means your battery stats is ruined. wipe it, but the battery drain on idle mode isn't about the stats.

If you're charging via USB, you may wish to connect to AC. USB doesn't charge as fast and your phone (apps running, etc) may using power faster than the USB can replenish it.
If you're on AC, turn the phone off and charge it that way. If it continues to decrease this way, there is something seriously weird with your device.

I re-flashed bionix but the battery drain still continues.. Should I change back to toxic darky 9.5 and see how the battery on that thing is working?

My Battery Percentage Increases...

First of all, I know what most people will say: wipe battery stats and condition the battery, but I'm too lazy.
So recently I've been noticing that sometimes my battery charge percentage goes up rather than down. For example, tonight I put my phone in my pocket at 18% battery left. I watched some tv and checked it again ~1.5 hours later to find that it was now at 32%. I've seen this happen on occasion before, but never such a significant jump.
Anybody have any clue as to why it would do this? Other than the fact that my battery stats are needing to be wiped. idk just seems weird to me

Sometimes that happens after a random reboot, where when it comes back up, it has "dropped battery." Then it realizes it isn't actually that low, so the battery meter will climb till it actually equals the battery. Then it'll start dropping again.

That was happening to me on Clean GB, I reboot my phone every 4 days or so and my percentage would drop significantly after booting back up, then start increasing. I've never wiped my battery stats. I'm using another stock-like ROM so I'll see if it happens again.

When you reboot do it while plugged into a charger and that won't happen. It is a glitch in CWM and battery stats.

"Conditioning your battery" after wiping battery stats takes nothing more than regular usage of your phone. All the people that say you have to do all that stuff after calibration are just recommending it because it causes your phone to adjust faster.
Just charge it all the way and use battery calibration to wipe stats. Your battery life will take a few days of use to improve to good levels, but it works and you don't have to do anything other than what you normally do with your phone.

let the battery fully discharge and then charge it. I was having a similar situation but I found out that the battery charge wasn't displaying correctly. A complete discharge recharge cycle improve the situation, although it still doesn't so charge up to 100%, stays at 93/94%.

Did you do a full wipe after you updated to 4.0.3? I'm seeing about the same battery usage after the update (maybe even longer battery life). There are some apps that are not very compatible with ICS that could be causing problems as well.

Yes, I did a full wipe using the flashable ROM-Wiper and Dalvik-Wiper.
As for apps, I don't have many apps. I just use this phone for messaging, RSS reading, and some little browsing.

Why don't you do a manual wipe. That might be better. Also mess around with some CPU and governor settings (which includes flashing a new kernel and ROM).
