Losing Battery life pretty fast now.. why?

I flashed my vibrant to bionix 1.3.1 a while back, pretty much a week after is was released. Its been great up to about 2-3 days ago. I had a full charge at work at today around 2 pm, I got home and checked the battery life at around 6 pm it was at 72%. I sent out about 4 texts lastnight. Got up this morning is was at 44%. I used to get about 2-3 days out of light use. It will probably be dead by 2 pm again today.
What gives?
Network data off -
Black background -
Brightness is the lowest -

Idk maybe randomly reading it wrong? P.s. Why dont people charge their phones at night?!?!? Thats what I do

Oh i do as well usually. But like i said, the battery is starting to drop so fast that by lunch that day it was already at like 49%. By 2 pm is was full and so on. I just dont understand why its dropping so fast thats all.
Might have something to do with the battery

Check what's running in the background. The other night I was just using the phone normally and put it to sleep, checked it a few times and it was dropping 1% every 15 minutes or so. Noticed it kept checking into something. VVM and Market Checkin was running, killed it and it seemed to help. Also discovered (might not be true) that the New MAPS and GMAIL apps constantly check in and drain the battery after removing the updates phone seems to last longer/as it did before..:/

oo maybe that might be it. I Just updated a boat load of my apps a few days ago. P.s. how do you remove just the update?

those are just a few tips , if You didn't install anything that would change Your battery behavior TRY TO CHARGE YOUR PHONE IN WALL OUTLET INSTEAD OF COMUPUER USB ,also did You flash any updates to Bionix that got released because of so some of them contain update to modem so if previous bionix was on JL4 modem which is fast and battery savy new update might off reflashed your modem to newer one as fast as old but with worst battery . good luck i can give u million tips how to save juice , oh btw :
http://forum.xda-developers.com/showthread.php?t=931351
also clean up Your battery stats in clockwork and recharge it with wall outlet Your battery might be recalibrated and when it shows 2% left u might have 10 really instead that's why clean battery stats and recharge.

or sadlly Your battery cant hold the juice anymore because it was recharged to zero few times too many , sorry

This is crazy. I just came to xda to post my bionix 1.3.1 battery problem. I been running it for a week and no issues. But this morning I took the phone off the charger and within 10 minutes of using it I was down to 85%. Usually after my morning usage I'd be around 93-95%. But that's not the issue I wanted to post.
I was trying to wait for Black Ice since Frost had the best battery life of any rom I've tried...just not feeling the Frost theme. So I started to download the Frost zip & got the phone on the charger.
Even after I put it back on the charger my battery life kept going down. Plugged it in at 85% and a few minutes later I noticed it was at 83%

Just go to the market, tap menu and then go to DOWNLOADS
look for GMAIL and MAPS, click on them and then where it says "Uninstall update" you want to click that. Done.

truee u might want to disable location access if its on too

if u updated ,find out which modem the previous rom u ran and reflash it to the modem u had before.

I had this problem with nero after a month of use. Wipe battery stats when the battery is fully drained. Fixed my battery problems.

I have the same problem. I have system panel running all the time. When I sleep, the phone sleeps too and uses about 1% of battery per hour. But when im actually using the phone, even if the use is minimal like sending a few texts etc. The battery consumption is far greater than the use. Top apps in system panel monitoring is usually system process and system itself. How do I correct this issue?

I had a issue a while back. What I did to fix it is go with the standard rom. Then slowly I would put one or 2 apps back on. After a day or so I found out which one was to blame and got rid of it.

Dont worry too much...Considering if your phone is new, the battery need conditioning. Just use it for a week with full charge cycle, I am sure it will be normal. Also you can check from battery usage, to make sure it's not some apps you installed that caused the heavy drain.

This is standard in the first few days; 4 days into me having mine, I noticed a decrease from 100% to 31% in 6.5 hours without even touching the phone, however now it runs a breeze.
I wouldn't say wait for it to mellow out and it will be perfect (although you can sit it out, regardless of what you do the phone battery will still need to adjust) but in the long run I'd suggest making use of the handy new battery management feature (Home, Menu, Settings, Applications, Battery Use) and also an application called Advanced Task Killer, which will manage applications that are loaded in memory on the phone. Some say this helps, some say it doesnt, but I personally feel it's beneficial to have it installed.

Be very careful if you're running Kakaotalk or Whatsapp - they drink battery power like mad.

Just be careful with running apps and widgets - I've put my WiFi sleep policy to when screen is off too.
Really pleased with my battery life - getting between 18 - 24 hours of pretty heavy use per charge

I'm tired of answering this question... please use the SEARCH feature.

I have the same problem with battery drain... When I restart the phone the problem dispersers for some time... I have only installed a few apps that I have used without problems on my HTC HD2.. I have run a lot of different android roms on HD2 without this kind of problem..
Actual I noticed the battery drain problem from first start on my ARC..
Now I have installed the "Only Battery Widget" and on the graph I can clearly see that the battery drain is lower after a restart.
I don't know when or why the problem appear...

I have the same problem before! However, after uninstall task killer program, disable Bravia engine, install shutupbatterysaver and do a reboot, the battery problem has gone!

I see Whatsapp is always in the "Running" apps list after restart. I don't use it.
I don't have an account and I tried to open the app once but did not register or agree to the terms.
It shouldn't use a lot of battery right?

It's installed on mine too but does not use much.
Kakaotalk, on the other hand, accounted for 22% of my battery usage - and I wasn't even using it!!
Uninstalled it.

my 1st proper days usage today and i got 19hrs at which point i hit 15% battery so stuck it back on charge, i was messing with the phone all day, quite a bit of gaming, 3 or 4 videos, pictures net etc, screen on auto, i have no task killer installed... i feel that when ive come out of a game when i check whats running its not there so no need as far as i can see to have 1, pleased with the battery it hasnt yet been through any cycles, this is the 1st time ive properly charged it

The battery drain from first day to third day is extremly different!
First day battery drained about 10% per hour idle,third day 2% only

Same here.
I notice there a lot of background services running on the ARC as compared to my Galaxy S and they cannot be stopped (keep coming back) or uninstalled.
I am using Green Power Free set to 1 min ON and 5 mins OFF to see if things get any better.

My Arc drain almost 30% over night with data off. I did a hard reset, it drop only 3%

For that matter I'll have to ask something... Is it detrimental to my battery's health when I charge it while still being halfway full? Does it hamper the total capacity? Because that's what I have to do sometimes because of school... Don't want an almost-empty battery there

Mine is new (less than a week) so shouldn't need hard reset right? Anyway, the Green Power seem to does its job, 68% now after 7.5 hours.

Theoretically Lithium batteries shouldn't be a problem since there is no memory effect. Just do a complete charge/discharge/charge cycle once a month or so to "calibrate" the battery meter.
You should also do it once or twice when new.

One more thing, I am using third party micro usb charger, the phone screen unlock not working!!! Which I cant unlock the phone while i charge!! Just be more careful. Or any friend have this issue?

Hi, it happened to me too. My battery started draining faster. I was not able to figure out which app caused it, may be WhatsTheApp or Evernote. So I took a backup and made a factory reset. Now my battery is back to normal. you can try that. Now I'm getting 2 days even after playing some HD games. Really loving this phone. Hope this helps....

Battery lasts around 10 hours with light to medium usage (its a new original Samsung battery as well).
Does anyone have any quick advice to fix this? Bit under time pressure due to job at the moment and don't have much time to research this. Any advice to fix this easily and quickly?

I had this problem after switching on the “Vorabruf über Mobilnetz“ in the Cache-Settings of Google Maps. Maps was closed, but battery was fast going down. Using XWJVH.

I too have almost the same problem with Darky Rom 10.1 - but I've heard that it has been fixed in the new beta version. I'm gonna flash it at the end of the week and after a few days of observing, I'm gonna tell you the results.

It's been through quite a few cycles.

I think I figured it out.....I think it was Skype. If you sign in the app is always on...it doesn't have an exit feature. There is, however, an app to close it. I used it and got normal battery life today!
We'll see if it keeps working like it should.

So I've upgraded to 2.3.4, (Ficeto.Deodexed.XXJVP) and Android OS battery drain stopped. Now it shows 70% battery usage on display (before it was 70% android OS). I recommend updating your system too

with darky on medium use never had more than 14 hrs )

I've given up for the moment and gone back to Darkys 9.5
Now at least I can get through one whole day and have about 40% left

Are you willing to flash the rom again? or you can try to use the speedmod 15g t11 for the kernel to replace the JVP kernel.

it's said that when you use the USB connection to your PC, you need to reboot it. So this battery drainage will not happen.
In the ROm 2.3.3 JV5 and JV6 for Asia, I do the same to keep the batter alive.

Try backing up everything and then factory reset phone. Generally this happens because of a few unwanted applications excessively using ur processor, in turn draining battery or there may be a malware that stealthily connects itself to the net. This will almost certainly cure the disease. If it doesn't, then there is a serious defect in ur hardware or some of ur system app required for properfunctioning of the phone is corrupted, causing excess pressure on the processor

It is a big problem to everyone, I charge twice per day for this.

Calibrate your battery
Let the battery go down to 0% and turn off
Then turn the phone on, it'll turn itself off again cause battery is low
Keep doing this until its totally 0%
Plug in the charger, charge it to 100%
Turn the phone on
Download SGS Tools from the android market place
Run the app
Go to "scripts"
click delete battery stats
Unplug charger & you're done
battery should be more stable now
go to settings
applications
running services
check what you have in the background
close them down if they're unecessary
I get through the workday with only 10% loss

If you have an really old SIM card, try and replace it with a brand new one. This may also help. I had bad battery run time with two LG Optimus 2x phones (about 10 hours) and not so stellar 20 hours with the i9000. Finally I stumbled over some advise to replace old SIM cards. Since mine was over 12 years old, I ordered a new one. It is not gonna change the world, I know, but it was worth a try .

Extreme Battery Level Drop After Reboot, Increases During Use

The topic pretty much explains it. I've been using different modified stock roms and now I'm on the latest nightly of CM7, and I keep having this issue. After a reboot at around 50%, the battery drops to 15%. The weird part is that while I continue to use the phone, it slowly rises back up to sometimes 30% and then starts going back down. I've always cleared battery stats when flashing and calibrated (which I believe is unnecessary), but I don't know if this is a problem with the battery, the phone, or if anyone else is having the same issue?
Attached is a screenshot of battery usage. You can see I never actually charged the phone.

anyway guys, you need to recalibrate your battery, its not being read accuracy.
download BatteryCalibration from the market, charge your phone till 100% (not just 100% but when it beeps, that its truely at 100%), then use BatteryCalibration to calibrate your battery, and then drain it to 0.. (crank full brightness, turn on LED flashlight, blast internet radio, whatever makes it drain faster to get this part overwith), then recharge it to max.
so;
charge to full 100%
while still plugged in, run BatteryCalibration
discharge to 0%
recharge to 100%
battery successfully calibrated, you will now have an accurate reading

I had exactly the same issue on 3 different custom roms....finally resolved by going bck to stock rom

did you
did you rsolve the problem ? how? I have the same problem and I tried more stock roms ... I don't know what tot do ....

Its nothing to do with calibration etc, its just how the fuel gauge chip works, it learns and more accurately reports usage over time. For example, if you reboot and (I can't remember the actual voltages for the S2) you have 1200mV, the chip goes, "ah, that is 15% battery." Then as you use it more, it relearns its settings and goes "aaah, my mistake 1200mV is really 30% battery. I'll display that instead."
Its been covered frequently that "calibrating" the battery of the S2 in any way but actually using it, is next to useless.

same here and I got the 2000 mAh samsung battery back in the days but now it happens with both of them also when my phone shuts off the screen brightness start flashing weirdly

Battery flat over night/ phone shut down with strange battery usage (screens iside)

I have samsung galaxy s2 just over a month or so and i have big problems, due to battery. I know this is common issue on this device.
Until now i try to recalibrate battery like that, no hard reset. The phone it;s new and it had ICS 4.04 installed on the first place.
1) drain all of your battery untill phone shuts down
2) turn on and drain battery until phone shuts down ( repeat until you are unable to turn the phone on- this step is very important because we need to drain the battery competely)
3) take the battery out and wait 5 seconds or so and put it back in
4) Charge the battery while the phone is off
5) when the charge is 100%, take the charger off then charge again to get 100% again
6) turn on your phone and enjoy your new battery
Once i try to take the battery out after charge, and wait over 2 minutes. I know this is a common issue of s2, but i have some screens, maby someone had similar problem.

Next, i'll try Battery Calibration (can't post the link, new user) tool from the market / wait for Jelly Bean official update. Then hard reset. Next step: service.

The batteries in these phones can't be calibrated per se. Just use it normally for a bit. The peaks and troughs in your battery graph are because you're clearing the fuel gauge data. Mine would drop from the 73% I'm on now, to about 14% if I cleared the fuel gauge chip data, until it relearnt its settings. Just charge normally and use it for a few days, it will sort itself out.
If not, new battery.

Im having the same problem. Tried swapping batteries with another S2, recalibrating the battery and even installed another rom, same problem persists. The phone will auto switch off after a few hours of not using (overnight especially), and batter will drain like mad when it happens. Brought the phone back to samsung for repair now.

I'm currently having the same (really annoying) problem. My international GS2 is less than a month old and uses the latest official firmware on ICS. It happens almost daily -- or should I say nightly? The phone has at least 60-70% of battery left by the time a go to sleep. When I wake up in the morning, it's completely depleted. My stats look exactly as in the screen-shots in the first post. I'm always charging/using it "normally" but it hasn't sorted itself out.
I don't really know how to solve this and it's frustrating. The Internet has mixed "feelings" about the solution(s)... However, same as with my battery issue, I'm looking for something more stable and reliable.
Am I missing something? Does anyone know the exact cause and how to fix it?

Hello, I took the phone to a local service (pointed by Samsung from my country) and they replaced my motherboard and another pice of hardware....something in the recharging sistem, i dont know details. I think there is a "lot' of bad motherboards... people form the service call it a generic name.
In conclusion, the problem was the motherboard, not battery. I have recovered the device from service one day ago, if i'll experience any problems... i'll get back with details.
Cheers
