Extreme Battery Level Drop After Reboot, Increases During Use - Galaxy S II General

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

Sorry guys, but your method with BatteryCalibration is useless ....
If you wanna do a correct calibration, look at here http://forum.xda-developers.com/showthread.php?t=1312273

Put back the battery on the right side.
8. Turn on the phone.
9. Pray the Battery god
And that post is just nonsense based on the old battery bump method .

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.

Sent from my GT-I9100 using XDA App

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.

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 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.

Annoying Battery Glitch

Ever since I've been on EG22, the battery has been very annoying. What I mean by this is if I charge the phone for a few hours (and don't take it off its charger), the second I pull it from its charger, it'll say my battery is at 85% or so. What I don't understand is when I put it on its charger, it is usually at ~90% so how is the battery being drained if it's on its charger?
Another annoying occurrence was when I decided to watch netflix and I left the charger on it even though it was full (Because I didn't want to waste any necessary battery). After the video was over, I pull it from its charger and see it's at 58%!
This has never happened before, so I believe it is EG22. Anyone have this experience?
I'm running Stock Deodexed EG22 w/ root.
Just guessing. I don't think android EVER charges the battery fully...its always around 90% even if it says 100% in android. Maybe eg22 is just shown the actual percentage?

I think some people are seeing this. Did you wipe battery stats in recovery? Also, I have been using "Battery Calibration" app by Ne'Ma. You plug the phone in to charge. When it gets to 100%, you get a tone. Then you just click to wipe the stats. It has actually been working really well for me.

How many times have you done this? I usually am not comfortable calibrating my battery since it always messes up the battery readings for me. One sec I can be at 90%, the next at 92.

Well, you have to understand I am switching ROMs 2 to 3 times a day with all of the testing I do. Its actually recommended that you wipe your battery stats any time you switch to a different ROM. After that, I let it drain to about 15% and recharge to full. The battery settles after about 2 days on a new setup for me.

This is an EG22/GB bug, the phone dosnt kick back in after hitting 100% once, and since the phone dosnt go into deep sleep when plugged in (stays at 100mhz or higher) your battery will get run down if not disconnected once charged."
this is post 55 from [ERA] EPICUREAN SCrAMbLED EGgs22 v 4 w/ EG22 PLUS
p.s. the best way to see your true "battery life" is to completely power off and take the battery out for 5 mins and put it back into the phone and power it on..i know this suggestion has nothing to do with your problem but i felt i had to mention it because the phone has wrong misreads sometimes even without calibrating...I'm not on eg22 btw..or you could just calibrate and see if the issue still persists...

Phone is getting to hot , i tryed to put others 2.3.7 and its same again what sholud i do.
solution i tryed: wipe battery stats -didnt help
going from 2.3.4 to 2.3.7 -didn help
PM me to see pic cuz i am new here so i cant post outside links at the moment.
Did you wipe data when updating to 2.3.7? If not, try it (maybe also without restoring stuff from backup, if wiping+restore does not help)
yes i always wipe data/cache/dalvik cache so tahts not issue,can i format SD card is she a problem maybe?
yeah same for me i am also using a rather new battery

what worked for me
Hi
I wanted to thank for Zoe Rom on its thread, but i cant write on developer's threads yet (altough i clicked thanks button there).
Im glad i finally got rid of my memory hogging default rom and now i have a properly working phone again!
Also i wanted to reply there (to some people also complaining about battery endurance on GT540 on Zoe Rom) how i fixed my battery main problem.
Pic of current battery drain:
http://postimage.org/image/d8o8uusd7/
As you can see i am aproximatelly at 50% battery after 1day and 11h of not charging.
I had 2 problems:
1- Battery lasted aproximatelly 5 hours on standby (and i mean i wouldnt even touch the phone and the battery was gonne after that time)
2- During intense battery drain usage, the battery was reporting to have less energy than what it actually has.
1st problem solved by simply turning off the wireless after im done with using it. No idea how could that be taking away so much energy, but it was. Somewhere during the period i was using my default rom i got used to have wireless always on, and my battery on the later times was going away faster than normal (i also like to listen to music on the phone). At the time i didnt correlate the 2 things, and i just put in my head that it probably was the battery dieing on me. It wasnt! The wireless (i suppose because of the Sync function also being on) has been draining my battery like mad between charges.
2nd problem persists. As you can see on the pic, those 2 spikes down correspond 2 diferent aproximatelly 1 GB file wireless transfers with Wifi File Browser app. This transfers (PC->Phone) make the phone CPU have to unzip the two 1GB files to the SD, so they are very CPU and SD card read/write intensive (i can force this battery drops with other instense battery use like playing a 3D game for example). The thing is if during that temporarly drop on the battery level measurement, the level hits 5%, the phone will shutdown. But to be honest, this problem is minor comparing to the 1st one.
There is one other minor problem with my battery, wich is the reading being inconsistent (drops 10%, then gains 15% then drops 5% again etc), but is this a problem at all?
I read a post of a guy that had made extensive testing to his battery cycles, providing loads of graph of battery levels (cant find link) . I didnt read through all of it, but i remember the guy saying something in the end like "Dont be too paranoid with your battery levels, as they arent accurate. Instead use your phone normally and you will gain an idea of how long will it last with certain types of usage"
By the way, he also said for people to just charge their battery whenever they could/wanted as it has no negative impact on battery life. I also read a bit of a paper on lithium-ion batteries stating the same, so no more forcing full-discharges for me!
One last thing! Deleting the batterystats file is as simple as disconnecting your phone from the charger.Why? because that file serves solely the purpose of suplying the UI with info of the battery drain usage on the current battery cycle.
http://www.xda-developers.com/android/google-engineer-debunks-myth-wiping-battery-stats-does-not-improve-battery-life/
And you can confirm this if you unplug your phone while looking at yout battery stats.
I hope this helps
PS: pls notice that it could have been not the wireless itself that causes the battery drain, but some service using the wireless. Finding this would require more extensive testing.

Update
Hello again
I just wanted to give an update on the situation since i noticed this post is linked from the Zoe Rom thread.
Two days ago i bought a new battery, an unbranded one (cost me 15€ here in Portugal). The shop had a legit LG battery for 37.50€ but i tought it wasnt worth the money. This battery has the same specs as the original, except it is 1300mAh compared to the 1500mAh of the original.
I dont have any battery related problem any more. Yesterday i woke up (100% battery), unplugged the phone, let the wireless on all morning, listened to 2-3 hours worth of tunes, browsed the web a bit, tested some messaging apps etc. Today i woke up, didnt charge during the night, and im sitting on 45% battery. Wish i had gotten a new battery sooner lol
With my old battery the phone wouldnt shutdown. It would always automatically restart. I had no ideia a malfunctioning battery could cause this.
I've have had similar problems with the battery on my GT540 with all cyanogenmods - 2.3.7, 4.0.4, 4.1.2. There were no such problems with original 2.1 I think it is the price for the newer versions, I can live with that, I don't have to buy new phone

It's normal after a couple of month of use, depends how many times you discharge your battery, remember...battery life it's very short on smarthphones.
lg gt 540 battery
Hi
I ve got LG GT OPTIMUS 540 android version- 2.1 and i have the same problem. If i dont use my phone batery can be dead in 5 hrs but if i use it 2-3hrs...my phone battery usage says android system eats 95%...is it norm or bad?

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.

But it's a new phone, new battery (
great
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.
Same here...

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

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...
