Hye everyone, my name is Ruben and I am 35 years old, I have a small goatee and my hair is thinning and I have a question.
Yesterday, Before I flashed a new ICS rom, my battery life is at 83% and after I flashed the rom my battery dropped drastically to 14%.. and after a while my battery started to increase to 16%,17% and after a while I ignore it and charged until it reached 100%, no issues until now..
My question is why is the battery indicator behave like this? is it okay to ignore it... If it doesn't what should I do to repair and avoid this.
p/s always do the 4 wiping before flashing to public.. sorry.. before flashing new rom. using 1 rom only, and from ICS to ICS.
Thank You.
Yes it's normal, the battery percentage does that when you just installed a new Rom. Leave it a while and it probably will settle. If do not, and it is actually a pretty normal thing with my phone, change the kernel (latest Siyah Kernel, 3.3.2, it makes my battery icon goes insane).
And it happens more often when you reboot your phone.
So.....

Why the battery goes crazy more often if I reboot my phone? can you give me scientific evidence on this behavior. Is this only graphical glitch or it directly effecting the battery itself. btw my battery only goes crazy only after flashing certain new rom.
p/s: maybe siyah 3.3.2 is a steroids for battery, yeah!! gokhan steroid...

Happens to everyone. Give it a full charge/discharge cycle to settle. 'Scientific evidence on this behaviour' ? Search XDA. There are dozens (at least) of threads/posts that have been written about the 'battery weirdness' of the SGS2 in the time I've been here.
It's a statistical glitch, nothing more. If it were happening with every rom you try even after that initial charge/discharge then maybe it's an issue with the battery.

Okay. Then it is decided.. Normal Behavior. Maybe there should be a new thread that titled as :Android, The Normal Weird behavior,that display the list of weird behavior that is normal that happens on android phone.. like mine was. or a thread that display the list of Normal Weird Behavior that happen to android users like Flashing disorder, craziness of F5 button, user became retard when rom has 3 days battery life.
I have an idea. How bout you start a thread like this ? I'm sure the community will be eternally grateful.

Hi guys sorry for this thread new here so please go easy on me. Had a galaxy s2 for a few weeks now and i have to say best phone ever. Did the normal rooting and flashing roms and i have noticed recently that my battery has been going down quite a lot after a few hours. I tried roms like Villainrom, Cognition, Batista and etc which i find them very good but on my battery stats it says that i have high display usage and the percentage is like 56 - 85 and sometimes goes and stays to 91. i have since then when back to 2.3.3 stock firmware rooted it as well and i only have display percentage of only 25% which i think is normal and my battery lasts longer. I have spoken to Samsung regarding this situation and they are sending me a new battery but im just wondering why i cant flash a custom rom without having to worry about the high display % and what can i do to fix it? do i have to give it a few days for the battery to settle on the rom or shall i just stay with the stock rom for now till i get my new battery and then try to flash? sorry for the long essay i just need to find out if any one else had the same problem as i really like to use a custom rom that my normal one.
THanks
I too find it very hard on the battery with all the custom roms that I have tried out. I tried, Villain, Cogniton, LeoMar, Batista, etc..etc..etc. I have in fact tried out all the ROMs out here. Tried even different combinations of Kernel, but all only lead to the frustration when it comes to battery life. I finally tried MIUI ROM and I can say that it is giving me very good battery life compared to other ROMs.
It is interesting to note from you that the STOCK ROM has given you better battery life. Could you please tell me how long did your battery last in Stock ROM and what are the Apps that were running in it?
Install Better Battery Stats, I don't think anything wrong with the battery.
See under Wakelocks what apps/processes are going in background and causing the drain. Then take necessary steps with TB Pro.

to xdadeveloporian: thanks for your reply bk and sorry to hear that you had the same issues. like i said above i am very new to all this so apologies if i am replying with noobish comments. with wifi on and the normal widgets i had a battery life over a day. only charged it once and it still going. is that rom that you using now good?
and to ithappy sorry what do you mean by your reply i do not understand sorry. and do you guys think with a new battery it will fix my problems and i will be able to flash roms or do i have a faulty phone?
% is not important, what really matters is total time on for the display. Are you sure it isn't that the stock ROM burns more power in other areas, so the display is less? Or maybe the brightness is different? I'm not even sure how the display proportion of battery drain is apportioned - is there really a current sense integrator?
now that i have the stock rom with firmware 2.3.3 display is 30% followed by android os 15 - 19% which i think is normal into regards were i was on customs roms and the os was 15% and display 50% and over. brightness is basically at the lowest i can put it i am using touchwiz launcher and i only have two pages with widgets and nothing else. just a bit confusing thats all. i mean with custom roms the battery should be alot better not the other way round if you get me.
apologies if im not making any sense here. thanks again for all your replies it does help

I don't believe that stuff, why battery life would be better in a Custom ROM, because they added/modified some stuffs, nah. You can make a Stock ROM custom with some little modifications if you are rooted and have great apps like Root Explorer, Titanium Backup etc. I, for me, will never ever use a Custom ROM. But that's just me, don't take it any personally.
And about battery, don't see that how long are you getting with it, like- 1 day, 2 days, they don't make any sense, just keep an eye on the 'Screen On' time, if that is around or above 5 hours then you are very fine. And also keep checking that your Awake and Screen On bar is synchronized or not, if it is not then you must have something going on background, like- Latitude, Email exchange etc. which you can see under Better Battery Stats. And also, when not needed turn off, 3G, Packet Data, WiFi, Auto Sync, Background Sync and check how many apps are on Auto Sync, if not needed then modify it to Manual Sync.
Regards.

Maybe they fixed some bugs - specifically a custom kernel might have improvements or bug fixes (since there is lots of work going on here from many companies making contributions). This takes time to filter through to the official ROMs.
Maybe they removed some of the stock apps which contribute (maybe only slightly) to power drain.
Maybe the small differences in the ROM mean that existing bugs are less likely to have an impact, so even not fixing the bug it seems to have gone away.
Custom ROMs are as likely to make things worse - but if many people are affected then it is likely that someone will track down the reason.
Look all i know is that as soon as i started flashing custom roms on my phone my battery life has been going down like hell. Checking battery stats the most thing that is taking up battery life is the display being as high as 80 even 90 percent. I am not a expert on android having had an iphone all my life so when people say underclocking and other stuff its like new things to me so i do apologise for being such a noob. i do love my galaxy and i think its the best phone out there at the moment. all i need to know is if there is something that i can do to bring the display down and not to have it drain so much out of the battery..
Thanks again for everyone for replying
very niceeeeeeeeeeeeeeeeee
huh? has anyone else experience high display usage on their phones when checking battery stats?
is that from the android market i can get that app?

I am on CM9 nightly and kernel that comes with it, latest updates always!
And yesterday I charged my SGS2 to 100% unplugged cable and at the morning when I checked it, it was dead! tried to go in download mode, it sayed battery level is too low! and really it drain 100% of battery in 8 hours idle!
Is it possible to fix such a issue?
Yes, by seeing what's using the battery, not by making a new thread with no useful information.

With the amount of battery threads that come up on this site it is surprising you haven't bumped into the routine of downloading betterbatterystats and seeing what is keeping your phone awake. You should also see if this happens on a fresh install with NONE of your apps installed. Completely stock with your contacts synced.
your issue sounds reasonable my device was awake on the 4/29 build, its best to talk about nightly builds in the discussion thread,charge it up and see whats keeping it awake
you wont get help without this
http://forum.xda-developers.com/showthread.php?t=1179809
Cyanogen9 is still deep in beta, that means it isn't finished, that means if you have a problem it's because the ROM isn't perfect. Why would you make a forum post about this? It happened once, not even a few times, why the **** would you make a post about something that happened once and you have done nothing to get to the bottom of it? Seriously what.
There are many stable Custom ROM of Android 4.0.x that you can use instead of CM9 'Nightly Builds'....

See this. While this isn't currently a "what's the best ROM" thread, the very nature of your question will result in the same debate those types of threads tend to generate.
Someone could really like a ROM and suggest it to you, and you try it, and you might decide it sucks. Try ROMs out yourself until you find one you like. Don't be lazy.

Hi,
My battery drops after every abnormal shut down, by pressing the power button for ~8 second. (I do this when the phone freeze.)
And when I turn my SGS2 on, some battery "disappear", sometimes 10%, sometimes 20%, or ever 50%.
For example, I have 90% of battery right before I shut it down (abnormal shut down) , and maybe I get only 50% of battery after I turn the phone on. It that possible that the battery drains 40% in 1 minute? Or it is normal because I shut it down improperly? (have a look of the attachment)
There is no problem if I reboot it normally.
I have two battery, having the same problem.
I face this issue in many ROMs, stock GB ROM, AOKP ROM, MIUI, etc.
I'm using Siyah Kernel 3.1.2 now.
Thanks for any help
(Sorry for my bad English)
I've heard a few users mention this battery drop and i've experienced it myself. It even happens sometimes if i restart my phone after flashing a mod or something.
You'll notice that the battery level starts to climb back up to where it left of (less the normal usage discharge)
Yep, normal on the SGS2.
Just part of the battery weirdness as a result of that fuel gauge chip. Entropy512 has written many a post on the subject if you feel like searching/reading up on it. Nothing to be alarmed about tho, and nothing you can fix. Just make sure you've got plenty of battery left before you do a flash.
On other hand, your freezes if regular is a worry!

Yup, my SGS2 freezes quite frequently after upgrading to Android 4.0.4.
Maybe I'll downgrade to 4.0.3, or perform a full wipe and flash the ROM again to fix this.

Battery drop is pretty common say 7 out of 10 times if you remove battery, after boot you will be 10-20 percent less. Specially if you change roms quickly..

Apart from the first few words of what you said (which I've omitted), what does the rest of it have to do with the OP's query about battery dropping after a dodgy shutdown or when flashing firmwares ?

Hello
I updated my Galaxy S2 via Odin(PC) from Stock 4.0.4 to Stock 4.1.2. All went fine, phone works smooth and fast. But there was a massive battery drain. Therefore i wiped data/cache, did a factory reset, everything is new an fresh. Phone still works smooth and fast but battery drain doesn't change. Take a look at the screenshot. Is there something i can check and change?
Thanx in advance.
Greetings

Chill let the rom settle for a while, the battery is usually weird after a flash use it for a few cycles and then it should be alright

Thanx for your reply. But i cannot confirm that. Never had such a behavior. Flashed a few ICS 4.0.3 and 4.0.4 Roms and either thery're draining or not unless i'm able to change or fix somthing. It never improves on its own. Maybe it's my bad luck only.

Yes, you are right. But i read a lot about battery drain problem in the dev thread and also tried a few, ok not all, things to fix it. Until nothing works for me i wanted to upload my battery stats but wasn't allowed to because i'm a noob. Therefore i opened up a new threat to upload my screenshot and hope someone has the right advice for me or just simply says "bad luck my friend. This Roms seems not to work for you".
And sorry again if i don't behave the right way.

Yes i will.
But, generally, flashing different Roms causes different issues. Reading solutions based on different ROMs, Custom ROMs, etc. isn't very helpful. There may be general solutions for this damn battery draining problem. But until now nothing fits to me.
In the end i hope to find a solution or i will go back to ics.

Your absolutly right, i read many problems, but with those stats are weird.
1) Just try to re-flash the ROM and after go to recovery and clear everything(dalvik, data etc).
2) Use the option to reboot.
3) Turn off phone -> remove the battery -> Try to turn the phone ON without battery one or 2 times -> wait 2-5minutes more without doing nothing -> Battery back in.
4) Charge up to 100% (when the icon appears).
5) Wait for 1-3 cycles and check if its ok.
6) If you have media draining check my signature link.
Issue solved, probably
I probably solved my battery drain issue while doing what CrisR82 suggested in his post here:
http://forum.xda-developers.com/showpost.php?p=37227296&postcount=10017
" Battery drain is caused by a permanent wake-lock (I had that issue).
For everyone with that problem, here's what I did and got rid of it:
1 - fully drain your battery (0%, to the point where it won't power-on at all)
2 - recharge your battery without turning on the phone
3 - go to recovery mode and wipe both data and cache
NOTE: backup all your contacts, messages, whatever...this will delete everything!
(I formatted my USB storage aswell before step 1, but I think that's not necessary)
No wake-lock for me, 17 hours use, 12% battery down (only checking the clock every once in a while)."
As it seems it worked for me also. Did it yesterday evening and keep in mind i did a factory reset therefore i had to reinstall everything. Battery is behaving normally again.
Maybe this helps the one or the other.

Now, right solution
Ok, my mistake!
At first it seems that there is an improvment in battery life like i said in the above post. There is ... but slightly. Not enough, not acceptable at all.
To make it short.
I did a clean install. That's it. Wiped everthing, pumped the battery up to 100% and flashed Samsung Stock jb 4.1.2 again. And it works now.
Thanks all for your advice.

My battery drained in 21 hours even after reinstalled everything after a full wipe. Couldn't find out what process caused the drain. Used bbs and its stats say android os, screen and Android in sleepmode is using most of the battery.
I'm back on 4.0.4 now. Waiting for next jb version.

Thought I should share that I tried the same and face the same issue. Before JB, on completely stock 4.0.4 (no root), I would charge after three full days (72 hrs). Moderate/normal use - no heavy gaming. Under JB it drained in less than 24 hrs with very moderate use - mostly idle. Back on ICS i now get the same battery time as before.
I should add that my phone came new with ICS 4.0.4 installed. Two friends of mine have upgraded theirs all the way from GB -> ICS -> JB and they exeperience significant battery improvement. Being a noob, I don't understand whether this makes any difference. Simply coincidence?
All the best.

New ROMs are always smoother than previous ones, once you flash em you get in cant-put-it-down mode. You need at least 1 week to judge battery life on any ROM. A couple of days to set it up and a few days to see how it behaves.
Once you get things going you never go back, that's a fact.
Be careful on 4.0.4.

Hello everybody,
about two months ago, I had an issue with my installed ROM on my Redmi Note 2 Prime (I think it was this one: http://forum.xda-developers.com/redmi-note-2/orig-development/rom-cyanogenmod-12-1-t3288916 ). I decided to try out another ROM so I installled Bule's Mokee ROM ( http://forum.xda-developers.com/red...nt/rom-cm-12-1-mokee-bule-mokee-blue-t3328382 ). After a few days with this ROM I recognized a big battery drain while screen off so I installed BetterBatteryStats to get some more informations. It told me that about 50-75% of the time my CPU was running at 800mhz instead of deepsleep (at a normal day with about 1-2h of Screen-On-Time). It didn't look to me like something is creating a wakelock though (but maybe I am just unable to see this). I tried the next ROM: Daniel Pinto's CM12.1 (http://forum.xda-developers.com/redmi-note-2/development/rom-unofficial-t3310551) and again the same issue! I tried a full wipe of my internal storage, did not install xposed and did not install any titanium backup. The battery drain didn't go away. So i flashed another ROM: SlimMIUI V7.1.3.0 ( http://forum.xda-developers.com/redmi-note-2/development/rom-slimmiui-dev-stable-t3296594 ) and suddenly there was no more screen off battery drain! This went well for about three weeks and now I am facing the old problem again! Please tell me what I am doing wrong since I don't believe it's a ROM-related issue.
I installed these apps (according to MIUI):
9gag
AdAway
Android System WebView
Antutu 3DBench
Antutu Benchmark
AquaMail
BetterBatteryStats
BikeComputer
Burning Series
Chrome
DB Navigator
Dropbox

Nova Launcher
Open Camera
PaderSprinter
QuickPic
scondoo

TeslaUnread
Titanium Backup
Twitch

Wakelock Detector Free
WhatsApp
Youtube
What I have tried so far:
- changing ROM (clean flash)
- not installing xposed
- not using old backups
- changing the battery
- using airplane mode
Also, I wonder why there are these gaps in the battery history since I didn't reboot yesterday...but these gaps don't appear every day.
Please help me to fix this really annoying problem and make my RN2 great again!
Thanks,
Kooneybert
The biggest drain comes from all the Xiaomi bloat. Read this thread for details on how to reduce the bloat. In my experience, the second main culprit is WhatsApp. I've had to stop it from giving sound notifications (or even vibrating) when messages come in. Now, I have between 90%-95% deep sleep on idle. Basically, anything that turns on audio could be a problem, because sometimes audio doesn't go off afterwards.
You might want to try GSAM Battery Monitor for more information about what is eating up your battery.

Thx for your reply! The problem is not MIUI-exclusive. CM 12.1 from Daniel Pinto is pretty slim but gave the same result (from the first day on).
Whatsapp can't be the only problem since all my friends use it and nobody have this problem (some of them also even have a RN2). Also, my phone is in silent mode almost all the time so no app is allowed to make noise or vibrate.
I just installed GSAM Battery Monitor but I don't know how to use the app/read the provided data. I could use some help there, too.

You can only be sure if you have a really skinny ROM whereby all the unnecessary Xiaomi stuff has been removed. There are all sorts of things going on in the background - including things embedded in the boot image.
There are also possibly optimisation issues with the kernel. All the ROMs seem to depend on the same binary kernels, since there is no GPL release of the kernel source code. You might want to try one of the skinny boot images by @jajk
As for GSAM, the best to learn is by trial and error (tip: tap on everything visible to see where it leads to, and what information it gives you).

...on all three ROMs? Only for me? With this effect? On some days, it reduces my battery by 50-80%! Hard to believe it is not a bug. Also, SlimMIUI has reduced Xiaomi-Stuff, Daniel Pinto's CM 12.1 looked even more clean to me.

Aren't there different kernels out there for the RN2? Bule's Mokee-ROM uses a modified kernel e.g. Does every ROM come with a certain kernel or may it be applied from the ROM before? So maybe I am still using the kernel from Bule's Rom with my MIUI?

This will help me to read the information but it won't help to understand them, too. What do you think about this:
Kernels: You can't compile a custom kernel without the Xiaomi kernel source code. All you are left with is tinkering with ramdisk in the boot image
Screenshots: the one on the right shows what is sucking your battery; the biggest culprits are the Xiaomi kernel and Google ...

...is this normal? The Kernel is the biggest battery sucker on my tablet aswell (which still has great battery). What do you think about the 8,5h of wakelock time produced by the kernel? If this is the problem, what can I do to solve it?

A "screen awake" of approximately 50% seems to me to be highly excessive (at least, if the phone was mostly idle). In nearly 12 hours, I have a screen awake of 55 minutes - so 8 hours in 15 hours seems strange. How exactly were you using your phone during this 15 hour period?
Perhaps the custom boot images by @jajk might help (see the first link in http://forum.xda-developers.com/redmi-note-2/general/roll-skinny-miui-t3309873). I am currently on v714-15 of the custom boot image.
Sounds like you may be having issues similar to what I was dealing with not too long ago, but my 'solution' was to install Bule's Mokee (still don't know why this ROM worked where so many others failed). Daniel's CM 12.1 and Xiaomi.eu were both giving me significant drain with and without the screen on to the point where I was sometimes finishing the day with an hour and a half of screen on time and ~20% battery. Now I'm getting up to double that.
One thing I can recommend is using MiFlash/Fastboot to do a total reset from scratch. Didn't really work for me, but you may be different.
Other than that, although it's tedious, you may have to install 1-3 apps per day after a fresh install to see if your battery holds at first and then dies sometime after installing certain culprits. It takes forever, but at least this helped me when I moved to Mokee to make sure that it wasn't any of my 'vital' apps that were causing me issues.
Best of luck!
Funny thing that the Mokee-Rom did SOLVE your problem. In my eyes this Rom was the beginning of my problems.

What is the difference to using TWRP?
I will try the Mokee-Rom tomorrow. Since I never used MiFlash/Fastboot before I won't use it until you tell me that there is a difference compared to doing a full wipe with TWRP.
I tried flashing the Mokee-Rom again but the problems go on. I installed very few apps and the battery is still very bad. Today I had 18 minutes of SOT and though I lost 14% in a few hours. This time it was caused by Whatsapp:
It always seems that some apps just don't like to stop doing something but it's random which app is the problem.
I am totally running out of ideas so please help me guys!
I'm on Mokee and satisfied with battery, this rom have less problems than other (for me). First of all i have installed MobileRadioActiveFix with xposed, then SmartNetwork to turn off wifi while my screen is off. I've got few other things but right now i've got over 4h SOT so it is not bad score.
i have the same problem! it happens with flashing severals ROMs (mokee by bule?) and starts battery drain with all ROM, it never goes... is not the battery, the cable or the rom..... i dont know im disperate... the sot changed from 4-4.5 h to 2-2.5 h... with all ROM, please help us and sorry for my bad english
Well i had situation that my SOT suddenly got down but i was still on march rom. After update to latest version without wipe it is ok right now.
Have you tried with wiping all with internal memory? Maybe something is there still and that is making a problem.
Another thing that came to my mind: have you changed build.prop and have copy of it? If so, delete it. I had some problems becuase of that.

every rom i have flashed was a clean install (full wipe of internal) after latest miui update, when the phone shut down at 0%, i put off the battery for 10 min, after i put back and the phone was at 19%!! now is on charge... maybe the problem is solved.. i will post if it is solved (sorry for my bad english)
I had that problem with earlier phone and it drived me crazy. I was not able to find what was the cause unfortunatelly. Phone was given to service point to install branded rom (it was not available for public). Right now i do not have problems like that, if i have some i'm able to find solution somehow. Although what i wrote helped me when i saw SOT problem.
problem persists... is there a method/app to calibrate battery that works?

Not that I know of. I`m facing the same issues like you here.
You can try:
-discharging until the phone shuts off
-charge it in OFF mode until its full
-disconnect charger, put battery out and in again
-connect charger, charge it to 100% again...
repeat until it shows 100% when connecting the charger.
For some ppl this seems to work.
Please let me know if you find out something!
There are lots of ppl out there with exact the same issue!

EDIT: Installed PSYROM V3 for testing purpose right now. Lets see how it does with skynet and a freshly calibrated Battery with the internal calibration tool of the rom. I`ll give feedback on monday.
Update to my issue:
-I did a full wipe (including internal memory)
-Installed PSY ROM V3.0 and Skynet
-Wiped cache/dalvic
-Startet the phone, installed my apps etc
-Charged it to 100%, waited 20 more minutes
-Did the Battery calibration with the internal calibration tool (everything is described in psy mans thread)
-Did a reboot
So far there is no Battery Drain, after the (long) reboot, wich took around 5-10min because miui is optimizing apps etc the phone came up with 97% and stayed there for almost an hour now.
I´ll give you guys feedback next week. Hopefully we get this sorted out.
You can try Angels & demons ROM v8.0 it is providing me with great battery life, so much better than stock or stable version of MIUI. I use Gsam battery monitor, and I have not faced that issue so far.
