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

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).
Sent from my GT-I9100 using xda premium

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.

Battery drain

Hello!
I rooted my phone as of yesterday, I charged it all night and when I took it off today the battery went from completely full to dead withint 3 hours of no use. I did not use the phone at all.
Any ideas?

If you just rooted your phone, you should not have battery drain... Try to temporarily disable root (with Voodo OTA RootKeeper for exemple)

Use better battery stats to nail down which app is causing the drain

Did you try wiping your battery stats in CWM - advanced?
There's also an app, Battery Calibration, on the Play Store that may help with that.
Not uncommon to get weird battery readings after changing rom's or rooting.

This is soooo strange. Not a normal behavior!! Before you root your phone, how the battery lifes goes??? Are you in a stock or modified ROM? Wich kernel are you using?
I faced this issue a couple weeks ago. Android S.O was the culprit and it was driving me crazy. I was using a custom ROM (RemICS-UX). I solved the problem returning to stock and erasing everything, then i reflashed the ROM and the kernel, in my case Devil3 0.79. If you want to give it a try!!
After that my batterys life is pretty fine, during at least 2 days!
Feel free to ask anything you want! Cheers mate
Sent from my GT-I9000 using xda app-developers app

Go through a couple more full charge cycles, if android os usage isn't very high then, it should be fine.
Edit: on second thought, draining the battery without use in 3 hours is extreme, and would suggest that the CPU is running at max speed all the time. If it doesn't solve itself or improve a lot after a few more charge cycles, reflash everything.
Using GT-I9000 my sent Tapatalk 2 from.

Did you just root your phone or did you flash another ROM? Some ROMs have horrible battery life.

The stock battery usage monitor (Settings>Battery) should be enough to tell you what ate your battery. If it's a particular app you're running, try disabling that and see if it improves. If the usage is mostly "Android System", "Mobile standby", or something like that, then you have a tougher problem. The free app CPU spy will let you know if something is keeping your CPU usage high. Better battery stats is pretty cheap and will give you much more specific information.

+1s for BetterBatteryStats and waiting a few charge cycles before judging/debugging your battery drain, especially if you changed your kernel to root or flashed a rom.
I find that after flashing a new rom or kernel my phone, the battery level shown in recovery mode is higher than in the rom's settings, for a couple days. (You can see batt level in semaphore's recovery). I once dud a lazy search about this and found nothing, but I figure that's what is meant about waiting a few cycles gir your battery to calibrate.

There's no such thing as "calibrating your battery". It's a myth. Wiping your battery stats file doesn't do anything other than reset the tracking of what's using power. It doesn't magically fix your battery meter. Flashing a new ROM doesn't leave left over data, again a myth.
Battery life is never consistent after flashing because your ROM needs to "settle" for a day or two first and during that time your ram and cpu usage are all over the place.
The rest is a placebo effect.

I think I may know what is happening to you as of now. Try to bring up the Battery settings if you are on ICS and take a screenshot and post it here. If my 'spider' senses are correct, your phone did not go to 'sleep' and remained awake.

Currently I'm experiencing a huge battery drain too. I used both tools which where mentioned here in this thread and when the drain occours, CPU spy reports that my SGS didnt go in deep sleep at all with turned off display, it was at least at 100mhz all the time! I attached 2 logs from better battery stats and it seems like the NotificationService is causing it?
I'm using JW6 PDA JW4 Modem and JVC CSC in combination with the MNGB 0.5.8 Kernel.

Definitely, now you got to find out what is causing it!

Poor Battery Life

I have the European version of the phone amd seem to suffer from poor batery life. The phone can barely be used 3 hours continously. I didn't fully charge the battery the first time so is this the cause? If yes how do I fix it? Also I have everything like Wi-fi etc off so that's not the cause.

if you're comfortable rooting/flashing custom roms onto your phone I'd suggest trying that. I get twice as much battery life out of my phone with the omega 28 rom

Give betterbatterystats a go..(free to xda members) and you'll be able to determine what programs etc are draining your battery.
Your screen time of 3 hours mind you is not too far off with what you can pull off with this device.. (4 hours tends to be a good number).. also taking into account the fact the device wasn't fully charged.

I`m on stock rom. I get more than 30 hours on one charge, internet, video, email normal use. Going through a whole day is absolutely no problem.
There must be a crappy app you`ve installed that is draining your battery. You will have to find out which one it is.

Are you playing games? They will drain your battery more quickly. Also, see if any apps are running in the background. After that, un-tick the location services in the settings menu. Change to a static wallpaper. Don't set very low sync times and turn your wifi off when you're not using it.
If you're on stock, you should have around 4 hours of screen time on.

I just want to confirm whether not charging the battery first has any effect on the battery life.

Bcos there's a good chance the battery may have fully discharged between the time it's packaged and when it gets to the end user, which in some cases may take months or even over a year.

[Help] Battery problem

My battery is draining too fast after upgrading to android 4.3. Even only on 2g there is 1% decrease in battery almost after every 3 minutes. But with screen off it will remain almost at 99% after even 12 hours or more. But when I start using the phone for something like even navigating through the settings the battery drops 1% every 3 minutes or even less. My handset is about a month old. I am from India and running the ML4 android 4.3 recently released by Samsung. There is no wakelock when the screen is asleep. The phone screen consumes between 60 to 90% of the battery or more. I factory reset it thrice since the update but with no effect. I am running the 4.3 update for about 3 weeks now. I also installed Greenify, battery doctor, juice defender etc to save battery but there is no improvement. I installed the same apps that I installed on the 4.1.2 firmware but the battery is draining quite faster in the 4.3 version. I also freeze almost all bloatware using Titanium backup and even uninstalled some like Google Books etc. but no use. I don't use wifi or wifi hotspot at all. I rarely use bluetooth. GPS, location, etc off. I even freeze Google Play store, Google play services and Google services framework. No multi window, no smart stay, no s voice, no ripple effect, no live wallpaper, etc everything off but still the same. If there is anyone facing this issue and has already found the solution, please help me out.

This is funny! You mean to say that the upgrade to android 4.3 has damaged my battery? The battery is not even 1 month old as I mentioned in the first post. The battery is very good on android 4.1.2...... As I mentioned in the first post, there is no battery drain when the screen is off. Even after 24 hours the battery is 99% from 100% with screen off. Why should I checked for wakelocks when the battery is fine on screen off? I did checked it to be sure but no wakelocks. The battery problem is when I use the phone, the battery is draining abnormally when the phone is used. Anyway thanks for your reply.

Using BetterBatteryStats will nevertheless help you to find out which process is consuming your battery…

Yes, 4.3 upgrade downgraded my battery life about 20% when I am using my phone. On idle it is better about 10-20% also compared with 4.1.2. It is useless to do factory resets or other nonsense. Just it is as is.

Okey So Firstly I rule Out Few Assumptions Made By Some Members(No Offense):
1) As thadoukuki said battery Drains only while using the phone and not wen its idle that means its not a wakelock for sure.
2)Secondly as the handset n battery ofcourse, are just a month old i dont even assume it to be damaged(Trust Sammy)
3)Thirdly 1% / 3Mins is quite normal on extensive Usage but as you say its just while navigating around settings etc. den i assume its a bit high.
4) Now betterbatterystats is good to identify what consumes your battery but ive never been a fan of that actually.
SO according to me try to do some trial n error work .
Instead of Freezing apps through TB u can use Greenify Donate to greenify system apps and user apps as well. It Does same job as TB freeze but without that extra hassle.
Secondly Choose a kernel that you think is battery friendly for you like the one which gives you peace of mind(Oh Yeah Battery's Draining Slow!!)
for me i'd go for Boeffla or Googymax
Choose a battery friendly Governer for ur CPU(For me Boeffla kernel with Archi_ultra_power_save governer gives great results)
Check if CPU Touch boost is Enabled in Kernel Settings coz Touch Boost gave me good performance and responsiveness but even i had observed that battery used to drain faster with it.
Battery friendly Rom with few Tweaks by xda members is always better for me over Stock( ArchiDroid Is the Rom ive ever Used){Personal Opinion}
Ppl Say undervolting helps .....hmm maybe ive never Done it but as you are very cautious about battery you may try it (on your own Risk)
Lets see if that Helps
And Lastly i never Observed much Change in Battery drain pattern wen Coming from 4.1.2 to 4.3 so thats not really true.

The draining nature of the battery depends on the rom and the kernel on how it optimises the usage of battery.
There are lots of tips to save battery. Google it.
You can use battery tweaks to get more performance in less consumption.
As there is no Ambient Light Sensor on Samsung Galaxy Y, I suggest you to adjust brightness often to save some life on the battery.
What I am hearing from you is new. I never heard that odexing a rom will increase battery life. I think you misunderstood it. Someone correct me if I am wrong.
You can follow a trick that is opted by me:
Charge your phone completely without disturbing.
Then use it until the battery reached 5% or nearby.
Then charge it again completely without disturbing.
This type of charging will help you get more battery life.
Press thanks if I have helped.

The draining nature of the battery depends on the rom and the kernel on how it optimises the usage of battery.
There are lots of tips to save battery. Google it.
You can use battery tweaks to get more performance in less consumption.

I agree. The key to save battery depends both on charging and the use you make of your phone. Battery saving tips are:
1. Disable animations.
2. Select a simple PNG, JPEG or BMP picture for home screen wallpaper, instead of a live wallpaper.
3. Adjust your brightness where you want to.
4. Use a launcher which doesn't consume a lot of RAM.
You can Google to learn more methods.
I hope I was helpful, if I was, you know what to do.

I just noticed with every custom rom I tried so far.. it drains a lot more battery than stock? is that normal? I even tried odexing the rom cause i i've read it gives you more battery and internal storage and it does give me a little bit more battery life.. but it's still not like the stock ones.. it still drains a bit faster? why is that??

You can check this thread on XDA. Features every possible way of battery saving. Featured on XDA Portal few days ago.
I agree with the_pirate_predator
that charging should be done 100% without disturbance and again put on charger when battery is approximately 5-10%. It is also suggested for other batteries like vehicle, UPS batteries etc.

it depends on many things..like roms kernels.. tweaks u uses.. use a good rom.. cm7 roms are more battery friendly than any other roms..
