Losing Battery life pretty fast now.. why? - Vibrant General

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.

CM5 or CM6 Battery Life ?

Which provides more battery life.
Im on CM5 now and my battery dies SO FAST you can almost see it going down just watching the screen, i have the screen turned all the way down, use only 2g networks. ever tried to under-clock, when i check battery usage says system idle uses 49%
any ideas ?
Are you serious?
Better yet, don't use the phone at all, that might save the battery.
Dude with those settings its like having a 20th Century device.
Flash another ROM or something, try wiping battery stats, it has been suggested all over the forum...
Why do I even bother...when the mods see this youre a gonner anyway.
It's not so much the ROM, its the apps and widgets you have installed. Some are poorly written, some don't play nice with other apps or certain set ups.
All you can do is install a monitoring app like system panel, and remove the apps that are using alot of CPU.
That's what I have done.

and thank you for your helpful reply i will look into the apps i have.
EDIT: Battery usage says system idle is nearly 50% of usage, even after i kill all the apps :[
LOL! Wow, someone's a little edgy...
It's definitely not a "CM5 issue" that would be fixed in CM6 (CM6 is still in RC, CM5 has had several stable releases!) eyegor's suggestion to wipe battery stats was probably good advice believe it or not. Charge full, power off, leave plugged in. Boot into recovery and wipe battery stats. Power down, unplug and start up, let it drain allllll the way.
Check out xda homepage even - a battery calibration post!!
Battery life is pretty variable as you can see in the numerous threads on this topic. CM's forum has one with a poll with most saying CM6 is better, but not a clear cut answer.
I used SystemPanel's monitor function to identify which app was eating battery. It worked great! My biggest offender was Weather and Toggle widget. I loved its customization but its battery gulping was just not worth it. Got rid of it and my battery life is much more consistent.
I also got a cheapie battery off eBay which helped.
Both CM5 and 6 run perfect on my phone. No battery drains.
My point was that you're in the wrong section, pal.
You also might want to watch logcat while the phone is idle or sleeping to see if there are numerous errors or warnings scrolling by when there should be very little activity.
I have a similar issue. Initially I had the rediculous drain, but as mentioned wiping battery stats from recovery fixed it for the most part. Once it says its fully charged and you turn the phone off, let it sit charging overnight. Then wipe the stats in the morning and don't charge again until the phone turns itself off. Only issue I have now is that when I've got my GPS turned on, in use or not, it kills the battery. While in use I get about 2 hours from a full battery to the phone turning itself off. Haven't figured that one out.

No worries. It freaked me out when I first flashed 5.0.8. I use my phone as an MP3 player in my truck with it plugged in to my CD players AUX Jack. Did a 5 hour road trip and only lost around 10% including a few phone calls.

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?

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 .

GingerBattery Sucks?

I dunno man, just gingerbread itself appears to have fubared my phone. I wiped sd, wiped phone, factory reset, odined stock EC05 and took the forced EI22 update. Even still, android system chews through battery at >90%. A small thermonuclear power plant could not give my phone enough juice.
This coming after I tried multiple combinations of roms, kernels, uninstalling apps, and freezing data sucking apps that caused high wake locks....
I have tried stock gingerBreadEI22, ACS 3.5 - 5.5, ERA RC1 & 2, and Random Rom, with nubernel, different samurai kernels, and just whatever the chef cooked up. All the same, excessively high "system" battery usage.
Anyone is / was having the same issues and able to iron it out?
That reading for system is the norm. I get 24 hours with like 80%

I agree with Alkah0liK, but with my experience so far, if I don't use the phone all day it doesn't really use the battery, but as soon as I start talking, listen to music, or web surf it because a pig. I actually want to go back to 2.2 and use frozen rom again from ACS again. Can't figure out how yet though

Ok thanks, I was wondering what others were seeing.
I must be doing something it does not like. I can go a couple minutes with the screen on (at lowest setting mind you) and watch the battery drop 2-3% or more, almost dead battery within 10 - 12 hours even in /out of airplane mode...
Is there something really wonky with CWM? Funny thing is this started happening right about the time i switched over to v5. I am in the process of reverting back to wiping everything, odin to EC05, and going v3.1.01 again.
The battery life is better with gingerbread, but its not going to make your phone run 2-3 days on one battery life. Sorry my friend, those days are long gone. It would be very hard to find any cell phone that can run for longer than 24 hours these days.
No I get that, but I was able to use my phone for more than a couple hours a day before gingerbread. B4 the leaks I was running Viper Rom EXT4 with genocide at 1200 ondemand and still getting through the day. If I cut it back to 1000 and went easy I was only charging overnight to bump it back up to full.
I was even using RandomKing's and ERA's leak based roms with EH06 & EH17 without any issue. For me it really has been either the EI22 / CWM5 / latest roms.
Hey alky, I was also in your position. I tried every rom you tried, with minimal pleasing. My advice, if you can live without 4g, flash the current cyanogen and set the render effect on night mode. Enjoy a thorough battery life my friend. Nothing beats it thus far. Can't wait till we see cm9.

Thanks! That was actually going to be my next try. I only get 4G when I am downtown, not very much as of late anyway.
FYI- I have found what I suspect as two possible culprits on ACS 5.1 & 5.5, and ERA RC1 & 2. According to better battery stats CM_VnoteService and *Sync for GTalk will run and run and run unless you open the applications and go through initial setup. Those two process will stay stopped so long as I leave them open / connected, once I close them - the partial wakelocks restart and run until you open the apps again (or just uninstall).
Even with my obsessively high amount of .acore launcher time and better batter stats application usage, they are still well below the "system" usage under the process dropdown.
It definately sips battery when not in use. Although I feel I get more screen on time with ACS ICS. I regularly have over 3 hours of screen on time with GB, I don't remember getting 3 hours on even SRF 1.2.

Turn off your syncs. If there is no signal your syncs will keep trying and burn up your battery. Turning off data mode in low to no signal areas will conserve battery.

Make sure upgrading to GB did not change any syncs. Also make sure new apps aren't loading into memory and sucking battery like Talk or Google +. Grab Memory Booster lite and pull up the task killer to see everything loading on your phone. The stock task killer sucks.
I recommend paying the $50 for battery and portable charger/storage unit. I'm a stock user who just had 41 hours with my new battery with 2hrs of screen time. I really like having two batteries too. No more charging cords connected to the phone...ever
Edit: the batt. I bought was a stock 1500mah batt. and charger kit from a sprint store. No regrets

Still running 100% ERA Legendary v4.0.1 (with provided kernel) and I squeezed ~74 hours of pure standby time out of my stock battery.
Data Sync (FB every 6hrs, Weather every 2hrs, Google push)/GPS/Auto Brightness = on
TWS = 4%
Display Time = ~24mins (sent 3 texts and checked 1 voicemail)
100% on 3G
Had I turned off all synching, GPS and lowered brightness all the way, I would have probably gotten 4 days.
Battery life has heavily depended on the strength of signal for me as well. I moved recently and have been living in the basement while the renovations are going on upstairs. No airave (it is used at a different location) means little to no signal in a brick house due to Sprint's POS signal frequency. Although I've been flashing different kernels and maybe not allowing them to settle + undervoling a bit (very conservatively, will not OC over 1100). But it is true that since days I was on BB Tour, not one phone lasted a full day without an extended battery. I'm pretty much decided on VZW switch once Prime comes out - one of the factors is better expected power management of ICS and possibility of adding an extended battery without worrying about making the phone too bulky (given how thin it is).
Man that sucks, I've always had great battery with gingerbread. Right now I'm on RC2

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

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.

i have the same problem when i use custom roms.
i have been using pure stock rom by wannam but rooted for the past week with 12 hours aday syncing and surfing the net and plenty of voice calls via viber and my battery lasts at least 16 to 18 hours.
right now i am using odexed KL3 Kernel KL2Base KL1modem 2.3.6 and it is absolutely amazing interms of battery life and performance.

Maybe, you wanna share a better way to all of us ?
Are you using speeded kernel. If you are then it is because logging and debugging is off.

Got the same here, very strange, on CM7

This thing only happens on CM7 for me. It had 40% before reboot and like 15% after. However mine only increased to about 17% then started dropping as usual. This never happened on any stock ROMs I've tried(stock, not themed/modded stock).

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.

I'm having this problem too, what did you all do besides get new phones?
Got the same here, after update stock jellybean
Had this problem, when my S2 was half a year old.
I got the original Extended Battery and that solved this issue completely.
The replacement Battery has held up since 2013

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

Very Strange Battery Stats - Help Appreciated

I've just flashed PA latest build (dirty) and my battery stats are pretty messed up, apparently Bluetooth was the biggest drain on my phone, 57%, and it was on for nearly 50 days.
I don't use Bluetooth and obviously a battery lasting 50 days is nonsense.
I've had a search and found people experiencing high drain from some services, or reporting 100% charge as soon as plugged in, but can't find anything resembling my problem.
Is there a way of resetting these stats without having to do a full wipe. I tried charging to 100% but they remain.
get battery calibration app, should delete the stats shouldnt it?

Waste of time. Just charge your phone to full and battery stats are wiped.

Thanks for replies. I did a charge last night but the stats remain. I probably didn't charge to 100% just almost 100%.
I find that it can take up to 30 minutes to go from 99% to 100%. I will leave it charging overnight and hopefully that will sort it
That Bluetooth figure just seems weird, and I have no idea where it came from??

I can't help myself........ Need attention
Seriously though it's a bit strange that we both got that, could these be the stats of the ROM builder and they got left in somehow?? I know the 15th June version wasn't official and just put out for feedback. Apart from the battery thing it's awesome

Probably, but I guess its just derp. Anyways running Franco kernel and PA on this and get 5.5 hrs of sot with YouTube and music playing all the time xda browsing Facebook and mostly on WiFi but on 3g when WiFi signal is lost when I go outside. Auto brightness on and screen does take up juice outside but I believe I could get 7 or 6 hrs if I played with settings, underclocked, minimum brightness etc...
