SOLVED: ICS Upgrade Myth Dispelled - Factory Reset Does Not Fix Battery Drain

EDIT: Please read this entire thread, there's some good info. Every phone and every situation is different, however it turns out my battery drain was the result of my phone not hitting "Deep Sleep". The culprit was my SD card, if you're experiencing battery drain after upgrading to ICS try removing your SD card and restarting your phone, use the app CPU SPY to verify your phone is now hitting "Deep Sleep". Again please read on, amidst some trolls there is more detailed information.
SIDENOTE: This being my first thread I have to say on the whole I really like this community!
I never thought I'd be that guy saying don't upgrade to ICS, because the OS is so slick and fun. However the glitch with the battery drain nullifies it's value. My brand new phone, less than two months old will die before the end of the day without me making a single phone call. I'm talking maybe an 1 to 1.5 hours of use texting, checking mail, surfing, and my battery now runs dead before I even get home from work. If you go into Settings > Battery it will show you the break down of what's using what. At the top should be your display, it takes a lot of power for to run the ultra bright display and this is what I saw before the ICS update. After the update these are the numbers:
Android OS: 58%
Screen: 18%
Cell Standby: 10%
Phone Idle: 7%
Android System: 2%
The OS is taking 58% of the battery?!? This is crazy!The buzz going around the net is if you do a factory reset it will fix the issue, well it does, but only for a very short time.
I went through the pain and formatted my SD card, then did a factory reset on my phone lost everything, well I backed it up, but still was a long process. After all that I loaded up my apps, and everything looked great. If you I went into the battery break down Screen was back at the top and the Android OS was several rungs below. I was SO happy! It was worth it after all.... THEN
Imagine my chagrin I woke up this morning to a full charge. Didn't make one phone call, just checked a couple emails, and being only a HOUR into my day my battery is at 76%!! I look back at the battery break down, and there's Android OS sitting at the top, draining double the battery juice as the screen display. I mean this almost makes ICS useless, what good is this great cell phone if you have to be tethered to a power cord. WTF!! Point being, don't bother resetting your phone, it DOES NOT permanently help. If you haven't upgraded to ICS don't, we're all just screwed until they come out with a fix, and you see how long it took them just to get ICS.
I don't know what happened between last night and today, but my hope is some dev person will read this and it will help them pinpoint the issue.

Did you backup and restore your app data as well?

Nope, the only thing I backed up was pics, music, and video, and I combed through those folders to make sure there were no sys files.

It sounds more like your battery is going bad. You can go to Sprint store and they will test your battery for you.
You might also want to get a battery monitoring program and see what is using the battery up.

its not a ics glitch its your phone lol.. ive never had this issue.. plus with the source kernels coming out and with roms/tweaks already out youcan increase battery life yourself.. because your battey cant keep a charge you bash ics? go back to gingerbread then lol. i can use my phone for two hours and leave it off charger over night and still have at least 50% charge

Having a bad battery would not make Android OS use the majority of his power though. I have had this problem myself in the past and never did figure out exactly what stopped it. Running Blue Kuban now and my battery life, though never great, is reasonable. FYI, I also run Juice Defender which makes a substantial difference for me.

Running pretty much stock ICS FF18, just have agat safe recovery/kernal installed. Yesterday I left Wimax on all day and when I went to charge it last night it had about 28% left. I made several phone calls, many texts/whatsapp messages, reading emails and using twiitter/fb a couple of times.
The battery life on this is not the greatest, for example, I forgot to turn off wifi when I left my house the other day, well my battery dropped about 30% in just a few hours. I now find that just leaving Wimax on all day is actually better and pretty much on par with just having 3G on, I prefer wifi at home but if I forget to turn it off it kills my battery.
I was so used to Blazers 4.1 battery life, the battery lasted forever and I could leave wifi, bluetooth etc on all day. Just hoping for the ROMs to start incorporating the recently released source so that we can get better battery life on these great ROMS.

This is all known information. That's why you use custom roms that have much better battery life.

I had same issue here with custom rom FF18 touched by SGS3. Went back to EL29, FF18 is glitchy and slower anyway.

Confirmed, factory reset battery drain exists.

OP, why don't you put up a screenshot of your battery graph? The expanded one, not the one that lists the percentages.
There are a number of reasons why this could be happening. One of my biggest drainers on CM9 was Google login service, turned out the "keep this device backed up with Google" in the backup and reset settings was completely preventing my phone from going to sleep. This is but one example.

You guys need to quit crying wolf and figure out what is really draining your battery. Maybe your google drive is syncing, or you have facebook running, or email is pulling too often, ICS does not kill battery rogue apps and wrong settings do.
Try this https://play.google.com/store/apps/details?id=com.asksven.betterbatterystats (search xda for other versions)
and this https://play.google.com/store/apps/details?id=nextapp.systempanel&hl=en
Figure out whats waking up your phone and running when its not supposed to be and until you have data STFU

seconded, attached is the battery stats for an average day for me on ff18 based goodness.... these "problems" are all able to be resolved rather easily with very little effort... this is not a paid tech support forum and no one is going to spoon feed you when solutions have been posted countless times in countless hysterical threads like this

My phone is not rooted and this is the battery life I'm getting after the OTA with light use. With regular use I get at least 25-30 hours.

Just curious, what's your display time. From the looks of it, doesn't seem like much. But still, that's pretty impressive nonetheless.

I'm a super n00b, if you or someone could link me to the best ICS ROM the cool kids are using I can figure out how to install it.
-----
However bottom line, before ICS upgrade my battery life was great and my Android OS was not 50% of my battery power. I'm not rooted or have any custom anything, after the ICS upgrade my battery drains rapidly. I'm willing to do what it takes to get it fixed, however I do fully put the blame on ICS, I'm using stock everything, the battery is good, something in that update is screwing my battery.
All I was trying to do was give developers, a little insight that the factory reset temporarily fixed the issue, for 3-4 hours before bed I monitored it and everything was good. So hopefully this will help turn the light bulb on in someone else's head.

ICS works really well for some, but for others it renders the phone completely useless. I'm one that it won't work for as well. The battery life is **** and 4g connectivity is non existent. As a result, I'm back to EL29/GB until a patch is made.
I spent 4 days after teh OTA was released trying to find fixes, trying to make it work, using different kernals and modems, but had no success. I posted about it many times and more or less was told that I was doing it wrong.
On that not, good luck mate. Here's to hoping for a patch from samsung soon. :good:

I have a thread stickied in general called "welcome to he et4g" that might be a good place for you to start, from there you'll figure out what you need to search for to learn more... there is no best rom its a matter of opinion, so read the dev threads and see what looks good to you... bottom line without seeing more information from you I would guess you have something running in the background preventing deep sleep, as mentioned earlier... also are you leaving wifi, Bluetooth, etc on? That'll kill your battery quick... do you live in an area with poor sprint signal? Constantly searching for service will also drain you battery. What do you have to set up to sync? And how often? There are easy ways to prolong battery life on ff18 and the vast majority of people complaining about battery life have not taken positive steps to learn more and resolve their own issues... it can be done, good luck

Note 2 Problems: After Official Updates

Hi! Guys, Well I bought my Note 2 in November 2012 with Multi Window update already Installed. Everything was So smooth and awesome until the Christmas update in India. My battery started draining comparatively fast but still not a huge change. But handset became little slow. That I consider Negligible. But then come the Jan update which I feel was quickly done to rectify that "root permission by default issue" like in S3. And after that am facing Issues like fast battery drain like previously when I used to sleep my battery drop by 1% only but for same amount of time when I check on waking up it had gone down by 7-8% and haven't installed any new apps so far.
But the biggest issue I face is that Note 2 won't charge sometimes then I have to restart my mobile and then it charges again and it happens quite often. Like I will face this 3-4 times in between 10 cycles of charging.
My Note 2 is not rooted for now.
Also a issue I have noticed that sometimes my camera images becomes corrupt on its own. This happened only 2 times though.
So, guys do share your advice/views on this.
Thanks
Also I have noticed that some times blue led blinks on its own. without any notification. And Smart alert doesn't go off, faced this rarely though.

You can TRY flash the latest FIRMWARE using ODIN... I'm not sure whether it will solve the battery drain issue but you cab try, but I personally think it's not too big difference...
For the battery drain issue, here is my suggestions:
1. Flash CUSTOM KERNEL, do undervolting your device, which I believe will significantly reduce the power usage...
2. Try use ONE POWER GUARD apk, I optimize the kernel and CPU, and other stuffs (Wi-Fi, 3G...) It's available in Google Play.
3. (I think you really need this if your battery is behaving as you mentioned) Do battery calibration, download BATTERY CALIBRATION in Google Play, charge your phone to 100%, open the app and tap BATTERY CALIBRATION. After that drain your battery until it switch off automatically, and charge your phone to 100% again in off mode...
And I'm so sorry to tell you that you need ROOT access then you only can try these solutions...
I also had battery drain issue before, but I found out that if you use all my suggestions, the battery life does INCREASE!
I flashed Perseus Kernel and undervolted my device using SET CPU... Battery drains about 6-8% in an hour with my Wi-Fi ON, Auto Brightness, and without turning off the screen to surf the WEB!
After that, I found out that my battery also drains about 7-10% after a whole night deep sleep, when I wake up in the morning.
I found the second solution, which is using the ONE POWER GUARD. Now, the battery life IMPROVES EVEN MORE! Now when I wake up to check my device, a whole night sleep is just draining 2-3% the most!
Thirdly, I accidentally found the Battery Calibration app in the Google Play...
I tried that but no difference, since you only need to use it when your battery starts to have problem (Others comment)
You can try this, I saw many good feetbacks from many users that it helps...
Now, I open my Wi-Fi all the time with Auto Brightness. I enjoy my music, video, web ever day. I finished charge my phone in 9 am yesterday, and now, I still have 51% to use XDA app to write this post Amazing isn't it!
ROOT YOUR PHONE, IT DEFINITELY WORTH TO SAVE YOUR BATTERY BY USING THESE SOLUTIONS... (My Opinion)
TRY THEM OUT BRO! GOOD LUCK

Thanks a lot for your suggestions.Will definitely gonna try these. And will surely root my phone once I get proper time to perform this ..
Yep I also think that these are cause of new kernel which samsung released hurriedly.
Will Contact Samsung and see what they gonna say.
And I checked my battery drain today with wifi & 3g off, Screen rotation off, sync disabled,location disabled,All motion disabled, pen detection battery save on but still ate my 5% of battery that too in sleep mode. Samsung's New updates have lot of bugs.
will root my mobile and will see how it performs. Thanks again for your valuable suggestion.
Ps;- I have also added some forgotten issues in my original post.

A lot of people complain of battery drain with their latest updates. I'm personally not too happy with it, but my device still lasts a whole day. I'll give Samsung another update to fix the issue. If they don't, I'm going back to 4.1.1 because I never had any issues there.
I've done a hard reset and nothing. Next time I'll try clearing all data and everything off of my storage and we'll see. Hopefully Samsung will fix this.

Indeed Samsung's new update has numerous bugs, hope they will fix it soon. 4.1.1 was Flawless.
And I doubt that clearing all the data will help as battery drain will be related to the new kernel and OS.
Let's see when will Samsung gonna release there new update to fix these issues.

I flashed the new MA6 French firmware, seems many MODs and Custom ROMs are released/updated based on this firmware...
I will see how it goes, I still using Perseus kernel, and ONE POWER GUARD.
So far, the results are not sure because now I have only tested it for 2 hours...
Hope it doesn't drain much battery... :laugh:

Same with me, it pinches me a lot to see my battery draining faster than before. And even I try to keep Hawk's eye on what's gulping my battery but so far I ll only blame it on new official samsung kernels.
But Well I guess Samsung has heard the cries of people and today I received two updates(OTA) mentioning Stability update. Hope this fixes this battery drain and other bugs. Also, now they included Google Play Music App in the update.
And after 4 hours of the update, battery life, I feel that it still draining quite fast but will test it in 2-3 days to be sure. Will update after few days of usage.
And thanks again for taking time to share your suggestions

Looks like the update was kinda dissapointed... It is quite battery draining after a day...
But I did try battery calibration as my solution, looks like is kinna sweet.
I charged my phone until 100% full this morning 11am and did battery calibration, now I still have 72% after listening music, surfing facebook, instagram, and twitter, with Wi-Fi on all the time and Auto Brightness on...
Anyone tried anything else?

Yep new updates doesn't resolve battery drain issue very much but its still better than before. During my sleep for around 8 hours, battery drain was just 2%, I was so happy but during normal usage, I still feel battery drain is little on higher side. I guess new updates do increase standby time but while on load it just doesn't performs like it used to be on 4.1.1.
That's sweet, you manage to get a lot of juice by those calibration. Currently Charging my phone and will see how it performs after a full charge cycle.

Well, 4.1.2 do drains a lot of juice from battery when compared to 4.1.1. Almost every Note2 has been plagued with this after updating to 4.1.2. That's kinda shame for Samsung that their new updates are battery juice guzzler.
And to resolve this battery drain issue you can wait for samsung to fix this in new updates or you can root and then install custom kernels and roms. And also please go through takumibunta's posts above, He shared very nice points to resolve battery drain issue.

have any of the ones who updated checked for sensors of movement and like that? i updated to avoid the SDS but after the first day I noticed that my phone was draining faster. I checked some things and some of them have been changed with the update (movement sensors is the only one that i can remember now) and now it last the same than before with some apps more such as xda app which it is said that drains also some battery
Hope it was just that the issue good luck!

Hi bro, I did some research before. 8 out of 10 people suggested do a battery calibration after flashing a new ROM. Well I tried and I think the results are good. I upgraded/flashed my firmwares four times since my first purchase. And I noticed it ate my battery when I flash a new firmware.
I did a battery calibration, it managed to hold more than 24 hours. I'm sorry I can't share my battery stats now because I just did calibration again to monitor my battery again so that I can ensure the accurate and 'real' result.
I'll keep you posted, let's see how the device go. Anyway, I still using a custom Kernel, did under-volt and using the ONE POWER GUARD app...
And 1 question, is your phone using all stock settings, ROM, and KERNEL??

Oh yeah I almost forgot to share with you guys.
I found an app called Android Tweaker. It is free from market. But I managed to get a PRO versions which contains full functions.
For details just refer the Google Play's descriptions...
Back to topic, I used this app to do some tweaks on the battery section which are increasing the Wi-Fi scan interval and Increase Deep Sleep Battery Life...
I will see is it able to push my battery saving 'limit' even LOWER. Now I'm still charging my phone. I will wipe my battery stats and monitor again... It takes time, and I hope it will show more significant result of maintaining battery life.
Try this app with CAUTION! It might cause BOOTLOOP or get STUCK at Samsung logo!
DO A NANDROID BACKUP BEFORE USING THIS APP! JUST IN CASE. I HAVE WARNED YOU ALL...
See you guys soon...

Lets first all agree in one thing to narrow down the source of the drainage. Is it the SCREEN ON is the eating your battery?
To answer your question im in stock rom and stock kernal with cf root only.
I know there are methods by using custom kernals and undervolting and supported apps.
Honestly I prefer to stable my stock rom and kernal battery usage first to last my battery more than 24 hours. So basically I like to work on stock because the majorty of the phones users are stock.
One thing I can try is battery calibration. Can you tell me the process?

Ok.
There is 2 options for your case.
Since you are using stock ROM & KERNEL, with ROOT access,
First option, I suggest you to use the ONE POWER GUARD app... The latest version is stable and there is a battery calibration function in the options.
Second option, download 'battery calibration' in the Google Play. Just for simple battery calibration only...
I STILL RECOMMEND ONE POWER GUARD. IT CAN OPTIMIZE YOUR KERNEL, ROM, WI-FI, 3G AND I/O SCHEDULER SO THAT TO MAINTAIN BATTERY LIFE. IT'S A NICE TRY.
Here is the step (The developer recommend us to follow these steps but not necessary)
THE FIRST AND SECOND STEP IS THE BATTERY CALIBRATION PROCESS
1. CHARGE your phone to 100%
2. Click on battery calibration button first (battery calibration app or ONE POWER GUARD app), then only plug off your charger.
THE THIRD AND FORTH STEP ARE NOT NECESSARY TO PERFORM, I TRIED AND I SUGGEST YOU TO DO THESE AS THEY CAN ASSURE YOUR BATTERY ACHIEVES THE MAXIMUM PERFORMANCE.
3. Drain your battery until it shut off completely, until you cannot switch on your phone...
4. CHARGE your phone again until full, without switching on your phone...
(Some people recommend to charge 4/5 hours to 'heat' the battery chemicals, I just forward their messages, I am not understand why to do that)

You are welcome. I understand how it feels when your battery is draining like hell. I will also try new things. Who knows? Maybe will find out something interesting
I am now trying the new app called Android Tweaker. So far, after my device is fully charged, I 'Skype' with my friends about 1 and a half hour, using XDA app about 1 hour, 'whatsapping' and watching music videos. They drained about 21% of battery in 5 hours. Unfortunately I rebooted my device to flash something and my battery stats had reset, it became inaccurate.
Looks like I have to wait until next round fully charge then I can make sure is the Android Tweaker helps me to reduce more battery usage.
But so far, I deep sleep my device about
6 hour. And I made several calls about 30 mins of total time. And I did set an alarm, I was too tired and I didn't hear it. The music was replaying about 30min Haha so embarrassing Now I still have 53% battery and I completed my charge at 2am in the morning.
According to my rough calculation, I have used my note 2 more than 11 hours (Including all the activities I mentioned above, and deep sleep time) ADD: Wi-Fi on all the time, motion on, and auto brightness on.
Looks like quite OK for me. But I still want to take a few days to observe few times so that I can provide a more accurate result to you all.
THANKS FOR YOUR APPRECIATION AND I WILL DO MY BEST. I'LL KEEP YOU POSTED BRO.

Wipe Data After Rom Update?

I was just wondering if it is advised formatting the phone after a rom update. I updated without from stock L4 to L7, and then to DMB3. I only wiped the cache and dalvic cache each time.
So I'm wondering, would I likely see any difference if I did a full wipe of my current rom abd starting fresh? The only reason I'm considering this is I'm hoping it will make a differencr to my idle battery drain.
Thanks.

Absolutely not. There is no meaning in wiping after you updated. It's only needed when you are downgrading.

Maybe someone can help or offer any advice? Over time I've made many tweaks eliminating as much as I can. But here are my recent battery stats in case someone can offer any help. The screen only taking up 29% is worrying. Also, I noticed an improvement when I turned wifi to go off with screen off... which is absurd really and clearly a bug.

Sorry to be rude but i dont quite see what the problem is? lol you getting nearly 2 days of battery out of a handset with a screen big enough to be a solar panel?? Even if i only use my handset for about 30% od its on time im looky to get 9 maybe 10 hours?
I think its awesome you have got it this long. Bur yh to reiterate do NOT format your device you will softbrick your phone. And factory reset is deleting the rom you have just installed.

Don't reboot in silent mode.
It's a bug.
Just reboot in normal mode.
If you are on 4.1.2 then don't expect more screen time for now.
Download rescan media root from play store and disable media scanner.

It's one day, not two. The problem being on 4.1.1 most of us could get almost 10 hours screen on time and closer to 2 days overall. It becomes a big issue when you know the battery should be much better, even if its still "good." No reason whatsoever for Samsung to destroy the amazing battery life of 4.1.1.

Yeah, so blame Samsung.
What you are getting is absolutely normal. I also had 9-10 hours of screen on time on 4.1.1. Don't know what Samsung ****ed up in 4.1.2, but I just never got that high screen on time! The max I got was 8 hours, god knows how, but that's just once.
I have switched to another kernel, NEAK to be precise, and I have already got 8+ hours screen on time twice. Maybe you could give it a try, until Samsung fixes this, that is if they fix it.

Thanks for the tip.
I'm on the LTE version so not sure if the kernel is availablr for it. But even so, I am forced to use stock rom and kernel so I can toggle root on and off and use the "SkyGo" app. Unfortunately the idiots at sky restricted it working on rooted phones and then only way to "trick" it to work is by using a stock rom and kernel.
Unfortunately I'm stuck with it and cant explore anything else without sacrificing that app.

As much as I respect your post, mine on stock 4.1.1, 4.1.2 and omega roms, had my screen brightness @30%. On ALL the roms after 7 hours of screen uptime my battery was between 30 and 35%. Wifi and data we set on only when needed.
I have much trouble believing you reached 2 days with 10h screen time, YES if you let it idle the rest of the time for one day extra. If you would have said 10 hours 1 day I would have believed you but the aabove story requires fission battery design.
There is some difference between roms in terms of drains but looking at that screenshot you barely reach half of the time you previously said you would. The difference proved it's way off by a far margin even for a bad rom. 10 hours even for a note 2 IS a killer, or better said you will definitely go under 30%.
Where I do agree with you... is that I get 2 days (nowdays) with screen br @40% on average 4-5 hours + wifi and data on.
On the positive side...no offence

It was closer to 2 days than one and around 10 hours screen on time. I remember being way over a day and I also remember being over 9 hours screen time a few times also.
The 4.1.2 update have brought about a big difference in battery drain and I won't get anywhere near that even after applying countless tweaks.
My HTC EVO 3D would possibly drain 1% overnight. The Note 2 drains around 10%.
Samsung have made a mess of the update and it is hard arguing against that. Maybe it's different for you because you turn off wifi and data. I don't and won't and haven't needed to on my previous phones.

Battery life with 4.4/Sense 5.5 update

Hey all,
Just wondering how people are doing on battery life after the update. I moved from BoneStock back to the stock(ish) ROM, and I personally am struggling on battery life right now. It is early though and I'll make adjustments. Just wondering how it's going for everyone else.

May be hard to compare a stock non-rooted phone to a custom ROM even if it stock. Seems like every dev puts in something "for better battery life"
I'm stock, locked, S-On, 4.4 and my battery life is great. Though I'm comparing it to my old phone, Rezound, where I couldn't get out my front door without it dropping 10%
I make it through a full day no problems and I'd consider myself an "average" user.

I haven't noticed a huge difference, but Bonestock 4.3 was definitely better. I'm on NuSense which isn't stock but it's pretty close with a few optimizations. Are you checking in the stats to see if it's an app that's killing your battery? I've had a few occasions when Google location services killed my battery for no apparent reason.

I haven't spent much time yet trying to identify and fix the issues, but I'll start looking at it. I wonder what it is they do to improve the battery life in the custom roms...

I tried the phone back when it was 4.2 and battery was not great, could barely make it till end of work.
Now on 4.4 battery has improved quite a bit. Can easily make it til end of day. Btw I'm s-off stock no root.

My wife's on a totally stock version of the phone, with the latest OTA. I'm on Santod's odexed rooted version of the OTA. 3.11.605.1 in both cases.
We're both seeing a slight decrease in battery life, but nothing too significant.
It's hard to compare battery life because I'm constantly messing with my phone, playing games, changing icon sets, making and deleting widgets etc., while my wife uses hers for phone calls and email and pretty much nothing else. She's never installed an app. I was going to S-off her phone, just to have it done, but our daughter installed the first OTA update before I got around to it. (The 2.10.605.1). She's 9, and enjoys showing my wife how to do stuff on her phone. Stuff that my wife then enjoys forgetting.
Having said that it's hard to compare battery life, I'll do just that. She gets better life than I do, and could likely go 48 hours on a charge. Her biggest power user is the email function - which is the stock email app that came with the phone.
Battery Guru used to tell me I could go 32 hours on a charge, but after flashing Santod's latest ROM I had to uninstall and reinstall it, and so far it's not giving me the same projected life numbers as it used to. I don't mean it's projecting less hours, I mean it's not giving hours of life expectancy at all. I can't remember if it took a few days last time before it started giving the projections - I only flashed the ROM last Friday.
Before the update I would be at somewhere between 70-80% at the end of a day, my wife would be 80+%. Now I'm closer to 60%, she's in the 70's.
My battery life may well improve still with Battery Guru. Would it make sense to re-install it on her phone and let it "learn" all over again?

the 4.4 update is draining too fast.

I went from the 4.2.2 BoneStock ROM to the new 4.4 version and my battery life easily doubled. I can make it about 28 hours on a full charge.

battery in 4.4 is s*ck.

i would prefer 4.3 for the battery life.

I noticed actually better battery life for 4.4 on bonestock. Im running with the elemental kernel and underclocked it, also i have some tweaks in tasker that keep my phone pretty efficient. overall i'm seeing around anywhere from 15 to 20 hours of battery life with depending on how long i have my bluetooth on and other things like that. ill post a screen shot later when i get home of my actual times.

I am having the strangest battery drain 4.4.2. 6-8 hours with less than an hour of screen time

I text a pretty good bit throughout the day and my battery life seems to go pretty quickly:/ I'm completely stock as well no root or anything.....yet. I'm hoping once they get a root/s-off/unlock method out for the 4.4.2/sense5.5 software, that I can do a custom Rom and fix all that.

With pretty heavy use I tend to see between 6 and 9% per hour according to better battery stats. My screen on percentage is probably within 18 to % most of the time. I'm running rooted stock with xposed and a tweak to stock that allows me to select power saver mode in settings.

temporary fix:
-Settings->Data Usage->(dots)->Restrict background data (yes this does make it harder to synchronize content)
-wifi off (if you have more than one bar of signal)
That temporary fix boosted my battery from a days use to two days. I blame Verizon for wakelocking our phone.

Hi there! Well, I consider myself an average user. Take a look at the screen shot. Numbers talk the best
BTW my SGN II gets about 5 hours of screen on time and has much bigger battery, so I'm happy with what I get on my One running 4.4.2 with sense 6.0 by hawk and ecliptic team powered by Lunar Ellie oc.

I think this should be the best phone for last year. S4 is overated for me since they have added a lot of stuff that we do not really use. here with my HTC one, it is customized the way we use it. And I can say the best part is that my battery can last for a day if my internet is off. If I'm casually using it with internet, it can run for almost 8 hours.

Battery problem (sudden drop below ~30%) even with new battery

Hey Guys!
I have a problem with my GT-I9195. I bougth it from second hand because my last phone's MB has died.
My battery was fine if charged over 30-35%, but nearly that point it drops by 1% every 4-5 seconds.
I bought a new battery because I thought it's just simply the battery. No. The problem persists.
With another charger, it persists too. I have stock rom, rooted and installed TWRP.
Mainly using root just to integrate system apps' updates.
I went to a service guy, who said it can be a processor problem, since the processor controls the charging.
My thoughts are the following after reading n+1 topics on xda about this:
Clean fresh stock ROM install - I don't think it will help me out.
Custom ROM - I think it will be worse.
Custom (maybe just fixed) kernel - ??? (I think could be viable.)
Changing mainboard, because processor controls charing and it may be failing. - I dont think so......
Changing this part in the phone:
Picture
Any suggestions, please?
Thanks in advance!

I have the same problem ... except that the battery will drop really quick when it hits 15% and die within a few minutes. As long as I keep the battery charged above 15%, all is fine.
I have tried the following:
1. "Re-calibrating" the battery - Let battery fully discharge till phone shuts off. Then charge till full, and restart phone. Rationale for this is that the phone may have an incorrect battery stats file, and thought the battery has more charge than actual, so even if the phone said battery is 15% (or whatever), the battery is actually dead.
This did not help me.
2. Install "Better Battery Stat" app, and monitor battery usage, in case a bad app is draining the battery. I did not detect any abnormal battery usage .
3. Clean install ROM. I was on stock, and I installed CM13. This did not solved the battery dying at 15% problem, but extended my phone's battery life. (I can routinely run 36 hrs or so with light usage before hitting 15%.) I presume this is due to getting rid of all the Samsung bloat ware. <Or maybe there was a bad app in the prev installation.>
I am now on Lineage 14.1 (Android 7.1.1). This ROM gives me ~10% improvement on battery life (compared to CM13), which I presume is due to improved Doze mode.
ATM I am getting good enough battery life out of the phone (~3 hr total screen on time, and up to 2 days of light/ mod use), so I have not pursue this further. I am simply treating this as phone not reading battery level properly and work around the limitations.
If you haven't, I would try the re-calibration trick. Didn't work for me, but may work for you. I have good luck going with custom rom (Lineage 14.1 by Arco is what I would suggest.) It extended the battery life of the phone to the point that I don't mind losing 15% capacity. <Might not work for you at 30% ....> I have seen some custom kernels that are supposed to give you faster charging (presumably by altering the charge rate algorithm). I don't think this would help as the problem appears to be problem of phone battery discharge / or the phone reading battery level correctly. <And messing with the charging algorithm is likely going to shorten battery longevity.>
Good luck. If you find a solution, please share!

I think most likely is that both your batteries are old, as the sudden drop is typical of old batteries. Even though you got a new one there are lots of dodgy batteries, according to many sources, sold on ebay etc so I suspect you have one got a bad one.

I bought factory battery, not a "chinese one", so I think it's not the source of the problem, but thank you anyway!

I tried to install that. Cannot work out to install gapps micro. Tried to zip-install LineAge, then install WebView choose Google WebView int the developer settings, then zip-install gapps micro. It always says setup wizard keeps closing, or something like that... :/ Have you got a solution for that?

I did a clean install using TWRP recovery. I downloaded the zip files for Lineage (from xda thread) , and OpenGapps (ARM, 7.1, micro) from http://opengapps.org/ (both to my SD card). From TWRP, I did a factory reset, then the install option. I selected both the files and hit (swipe) install. Worked like a charm. <Also did aroma as well, and that worked too.>
You are supposed to be able to first install the ram, then install OpenGapps at a later date. However, I had problem with the 2 step approach with my HTC One, so always installed both zips together since.

Hello guys!
The battery drop problem is a common failure with this i9195 phone. I did a research but you have to help me as well by providing IMEI S/N (located under the battery) in PM to me!
New battery doesn't helps!
My current research: If your phone made in Vietnam in the 1-line ~2013, then you will have a dead motherboard soon, before that battery issue is occuring.
So please give me your details and I will look after it.
Do anyone know when they stopped producing i9195 and i9195i ? I need to buy the latest version, because my i9195 was made in 2013 and have that battery drain issue even with new batteries...
Thanks.

I bought factory battery, not a "chinese one", so I think it's not the source of the problem, but thank you anyway!

Good, should be OK then, but keep in mind it's quite possible fake Samsung branded or genuine Samsung batteries that have been "reconditioned" find their way into shops.

Very interesting! I've thought for a long time there must be a bad batch that had a memory problem given the number of bricks on the S4 Mini thread. Though I did wonder if it was more likely the actual memory chip.
I've not seen anyone link the battery issue with the memory problem before, though it's possible, was there something that confirms this or just an educated guess? (edit: it has been suggested before that a low battery level could cause a memory corruption, though that seemed to be as the phone was shutting down not just losing charge quickly)
No, I don't know when they stopped mfg.

I think the problem could be that 2.6.x.x cannot do this.
I flashed yesterday with these TWRP 2.7.1.0, worked like a charm.
lineage-14.1-20170408-UNOFFICIAL-serranoltexx.zip
open_gapps-arm-7.1-aroma-20170409.zip
addonsu-arm-signed.zip
I had some problem soon: From 100%@2AM it discharged to 0%@10AM.
I did not even touched the phone... Kinda weird.

This screen means that the last recorded data from battery usage from GSam was - when my phone suddenly turned off -
was 37% ?! Really guys?
When I plugged in the charger, it said 15%....

I used the latest TWRP (3.0.2.1) to flash mine.
Can't say why you have that big drain at night. Perhaps an app updating? <And after a fresh install, many app will try to sync, etc.> Had that happen to me before - app tried to update overnight and killed the phone. <Bed room have patchy internet, and the constant reconnecting of a shaky internet signal drains the battery fast on my phone. <Now, I only allow update when phone is plugged in.>

that screen shot suggests it must be an app as 63% is very high if the phone was not used overnight, also if that was over night while you were sleeping then screen on time is high also. I would use apps to investigate wake locks and an app that shows cpu use for the app (unless your battery app shows each app)
But I still think there is something amiss with your battery as it shouldn't shut down suddenly from over 30% even using power at that rate with a good battery

You also may to try to download 'Repair battery life' from Play Store and it is free... After fully charged battery you may try also to calibrate your battery if you your phone is rooted and there are also few free calibrating apps on the Play Store with instructions how to do it...
Succes !!!
