[Q] Samsung Galaxy S2 GT I9100 heating up - General Questions and Answers

Ello Folks,
I'm new to this forum and for some stupid reason I can't post within the forum I wanted to, so I hope someone can help me here..
I have been playing with Custom Roms for a long time and I have ALWAYS encountered problems regarding battery drain. I have searched innumerous times for ways to fix it.. I've tried many different ROMS and KERNELS and I always ended up with a massive battery consumption with little use. I then thought it was my battery as the device is quite old so I decided to buy a new original battery and still having the same problem.
I am starting to think that I am really dumb and doing something wrong or maybe I am just unlucky. I got my phone back in 2011 from T-Mobile UK and I am now running JB 4.2.2 Revolt JB I9100 and Dorimanx V9.33 as kernel.
My battery is going from 100% to 0% in like 4 hours. Any help would be very much appreciated.
Thanks

Batter drain in 4 hours is not normal. But with heavy usage of 3g/4g it can be. As you said you got heating problems too.
So, first with the battery. Install betterbatterystats from play store. Let the battery drain off completely and charge it to 100 in a go keeping data network/Bluetooth/GPS/WiFi in off mode. Check how much time it's taking to charge it from 0% to 100%. Now discharge it off to 0% and Check the rate of discharge. If it's below 5%/Hour you are safe.
But if it is as you said before 4hours battery backup, there must be some trouble.
These kinds of drastic battery drain happens of many reasons.
1. Poor signal strength.
2. Overloading cpu ( which also cause overheating)
3. Any background running apps which utilizing a bunch a data.
4. Bad kernel (we can pick this out as you tried different kernels.)
5. Defective battery.
Or a last chance
6. A hardware failure.
So inorder to find the root cause behind this problem check each of the possibilities one at a time.
In case of cpu, change the governor and I/o scheduler and see.
In case of background running apps, check whichever programs revising maximum amount of battery.
Hope it helps..

Cheers mate,
I am well aware that custom kernels allow me to overclock it and change governors and i/o and that these kinda settings have a major role on how much battery the device will consume. But as I have never really understood the diferences btw them I for once have never played with the values so I have always left 'em at their default value.
The only real reason I've decided to change to a Custom Rom is to get new versions of the Android OS and to get rid of the hideous TouchWiz skin from Samsung..
I am not living in the UK at the moment as got transfered to Brazil for work and I have been on TIM network and they suck badly so maybe cuz their 3G sucks its whats causing my battery to drain like crazy.
But I will definitely follow your instructions and hopefully I'll get a positive result..
Once again, thank you very much.

Guess, I get to ask for help. [Ticket Closed for Now]

Background: I have had phone 11 months. I am very familiar with how the battery drain is while it is stock (WiFi ON all the time). battery lasted ~16h which is plenty for me.
Rooted phone, Battery Life on AR14 and IceColdSandwich (and others) was around 20h with WiFi on all the time and light use.
Recent Kernels (anything IceColdSandwich 3.0.0+ or AR 23+ (haven't tested between 14 and 23) cause a base of around 50mA of drain even when phone is locked. Battery life is ~8-10hours WITH NO USE. I have tried these ROMs without installing ANYTHING on them with the same results.
Current Widget does not identify an offending program from what I can tell.
WiFi off, the phone lasted 2d9hr of pretty light use.
I first started looking into WiFi when I forgot to turn off airdroid and unplugged the phone for 3 hours. I found AirDroid still running but could not connect to it via laptop or desktop until I tinkered with the phone a bit more and the WiFi connection cycled.
However during this time, the charge lost on the battery was a reasonable rate, and after the WiFi connection cycled it dropped like the usual rock.
What I've tried:
WiFix
WiFi polling interval increase
Cleaning/checking battery cover contacts
Changing battery covers
Battery Calibration (which is a myth from other reading I've done)
A couple of different programs like Juice Defender.
On the list to do:
Try a different Kernel
Root my friend's phone and trade him hardware (he says he never uses WiFi, so it won't be an issue for him)
/wrists
Thanks for all the suggestions and help so far. I understand that the problem is pretty obscure and seems rare.
on icecoldsandwich ive seen quite a few people show an improved battery draining using lordmods newer bfs kernel. maybe give that a try and report back?
http://forum.xda-developers.com/showthread.php?t=1450962
kernel: http://goo.gl/ZqBZl
btw, very good informative question. its heart warming usually we get 'my battery sucks yo, fix it!' haha
Here is some irony.
Exitz ICS AR25 has been on the phone for a couple of days and has lost essentially 10% per hour when not on the charger (been off work in my house) After the 4th day, I installed AirDroid and AngelCamera. I took it off the charger last night...
92% 6 hours later AND the phone has been awake(?) all night...
Seems I left AirDroid 'running' but couldn't connect to the phone through AirDroid until after the WiFi cycled...
I will see how the drain is today. I'll out of the house all day tomorrow (half a day in Denver), toggle off the wifi for a day at home, and then try your suggestion Darunion.
Here are a few screen shots (first two are old), and honestly, I don't know how much I trust the battery stats.
IceColdSandwich 2.0.0 pretty much shows that battery life I have been used to for a long time including before rooting. Not AMAZING, but not fail. (WTF Proximity Recaibrator 29% of Drain on a 16 hour day?) Also note this is about the same rate of drain I experienced with Existz AR14 last week. Light use and ~16-19 hours of battery life. Not amazing, but I can live with it.
IceColdSandwich 3.0.0 pretty much shows the battery life I have been getting with any ICS roms since.. well 3.0.0 was released. Oh and the voice call that is 37% of drain lasted less than 10 minutes.
Existz AR25 (someofthedrain.png) the steep drop was a 20 minute phone call...
And Finally Airdroidwtf.png is the same install three nights later (this morning) If I could get battery drain like THIS on a regular basis...
Anyway, I'll keep trying to isolate this down to the specific 'area' of the phone that is causing it....
Edit: and as for Darunion commenting about the information I've included... I'm a patient person, I don't want to be a drain on the community, and I have no issue trying to solve a ROM, APP, Radio, RIL, Or watever issue. I'm only posting because the issue isn't unique to a ROM but is unique to a time frame AND the issue is not solveable via Google or XDA search
Right now it is looking like the 'extra' drain on newer ROMs is directly related to the wireless being on*.
Right now the phone is at 1day 19 hours with 14% left and the wireless was only on for the first couple of hours this charge cycle.
I never thought there would be such a considerable difference between battery usage on any ROMs.
I'm going to continue looking around and trying to solve things, and I haven't quite made it to trying the Kernel, Darunion. It is on the list after I toggle WIFI on and off throughout a day.
*The rest of this post is just back-story I have ran the phone on stock for 11 months before rooting it and during that time, I got used to leaving the WIFI running all the time simply because the battery always lasted through my longer days and my-typical light-use. I'm near WIFI that my phone connects to about 80% of the time.
So after rooting, I had a little increase in battery life and I never changed this habbit, or more to the point, I was leaving WIFI on as to make it one less variable in drain while testing various ROMs and different build dates.

I was on battery for around 13 hours yesterday with wifi on for at least 8 hours of that and plugged my phone in with 51% battery remaining.

Yeah, I know this isn't a typical issue for most everyone, and am not implying so.
Likely it will end up being something very specific to the two WIFI networks I am at for 80% of the time OR something else that is very specific to my circumstances.

Have you, by chance, removed and reinstalled your back covers? I know it's unlikely, but since they contain the antennae, maybe they've come a little loos, resulting in higher imepedence connections.

I have not specifically toyed with the covers as part of trouble shooting. I will be sure that I look at them after my battery finishes charging on WIFI.
It does seem to be more a software difference, (I've casually be at this for the better part of 2 months) as I have seen expected performance when flashing back to a ROM I've used.
Thanks, I like being able to limit variables and this will be one I check before charging the phone again.
(What I'd really love to do is convince my brother or one of two friends who have the Inspire 4g to let me root their phones so I can trade them phones for a week and really isolate out hardware issues
fyi if you are still running icecoldsandwich. 6.2 just was released. Maybe give that a try?

Right now, I'd like to figure out WHY my WiFi is so bad on battery drain with later AOKP releases.
I'll try to rule out hardware issues (I'll look into antenna and MAYBE convince a friend to let me root their phone and trade them for a week... if not then covers at least.)
But likely this is something about newer releases and how my WIFI is setup. I don't live in a high-density area, so it's not because of too much wifi trafficz (I can barely see a 2nd wifi with any device and it's on the opposite end of the frequency choices.... by my settings)
Anyway, I am a very patient person, so I'll continue working on this slowly so that I can be thorough and find the real cause of the problem.
What I would wish is for someone to point me in the direction as to how WiFi MIGHT drain the battery so hard for later releases but not earlier. I'll be reading up more on logcat and how to read it in regards to wifi... but searching and reading is hard because 'wireless' and what not are very vague terms
Now at 1% (still) and 2d9h... is MORE than double my record on the first roms I tried after rooting OR my stock rom. and MORE than quadruple my record on any of the newer roms
I've swapped battery covers with a friend this past weekend, and the WiFi being on still drains the phone considerably (~8%/hr) when turned on. So if it's a hardware issue, it's not in the battery cover.
Wifi and blue tooth are very hard on the battery regardless. But 8% an hour seems pretty steep tho.
I would start by getting the current widget in Google market and put in on your home screen to monitor your Mili-volt ussage. If its running high like the 200+ constantly you have a lot of drain going on. When in sleep mode it should drop down to 0mv up to 8mv. If it stays high in the sleep mode you have apps waking your phone from sleeping. Which causes tremendous drain.
Next I'd try removing apps that have wifi permissions. To see if that drops your mv ussage.
Drop your notifications to less frequent times on your email and Facebook.
Remove any task managers or juice defender. They run constantly.
Google + is a massive battery drainer. Remove or limit notifications and sync as much as possible.
Also running wifi fix apk could also help. If you are knowledgeable enough you could also edit the build.prop to set the wife scan at a less frequent rate as well.
Last but not least get a toggle button widget for wifi and turn it off when not using.
I'd you follow these steps this will drasticly decrease your battery drain.

Thanks for taking the time for this response!
I started by running current widget for about a week and with a 3 different roms AR23(?), IceColdSandwich 2.0.0, IceColdSandwich 3.0.0.
I was stock for 11 months, and ICS2.0.0 was a little better than battery drain than stock. AR23 and ICS3.0.0 were terrible and pretty much ran a constant 50ma drain asleep or awake as a baseline.
I'd really like to figure out what the difference is with the older AOKP and the newer AOKP, but that may never happen.

I've been testing with stock roms since a couple weeks before I posted this thread. This is because current widget didn't really show any specific program causing the issue, so I wanted to make sure that I didn't have some issue from my installed programs.
The most I've installed (out of necessity is AirDroid and AngelCamera) in the past few weeks. Both were installed when I ran without wifi on one charge for 2d9hrs.
(I don't have a google+ account, I don't have juice defender or any task managers aside from the stock rom)
Also running wifi fix apk could also help. If you are knowledgeable enough you could also edit the build.prop to set the wife scan at a less frequent rate as well.

This is likely going to have to be my solution. Just run cell data all the time unless I am doing something specific like downloading files or uploading pictures.
OR
Maybe I can convince my friend to let me trade him phones (root his and nand backup and then restore all his stuff to my phone) and see if it is about the same drain. His phone was bought a couple months after mine AND from a different vendor, so it isn't going to be out of the same manufacturer's lot.
I'd you follow these steps this will drasticly decrease your battery drain.

Thanks again. I'll definitely try the wifix along with the rest of your suggestions that apply
I'm in the same boat you are. I'm running ics aospX ar-26 and I can barely get mine to last from 8 til 4. Wifi is pretty prevelent around here and I leave it on most of time. I guess I could try turning it off til I need it. Anyway I'll be following this thread.

You also might consider reading the threads on calibrating battery after flashing roms. I made the mistake of flashing a rom @ 40% battery. It jacked my stats all up. The new rom thought 40% battery was actually 100%. It had my stats all screwed up too. Except mine was Bluetooth. Showed running at 60% of battery ussage. So don't trust that system tool. Because the display is almost alway gonna be the biggest drain on the battery. An app called "spare parts" is a little more accurate.
I ran the gambit on this one finnally got my battery back to normal for me anyway. I've never seen a full days use with out charging. Get about 14 hours Max now. But the calibration steps is the way to go.

I actually have read quite a bit about battery calibration... and before I flashed a new ROM, I've made sure that current widget has been tracking 0ma for a while. (Only reliable way to be sure you have a full battery from what I can tell)
The batterystats.bin file and calibration has been ... contended in a number of places, mostly stating that when taken off the charger 'full' the battery stats file is overwritten... which makes calibration a non-issue (assuming that you occasionally charge your phone for a while after it hits 100% from time to time)
The problem is that the WiFi mA draw is HUGE compared to what it should be (in theory from reading other people's logs), and it's not because of the battery cover. AND It's not as bad in older AOKP ROMs than it is in newer ones. SO it could be a hardware issue exacerbated by a change in how WiFi is handled, but the hardware issue was never noticed because the battery life Stock was sufficient for my needs.
I've been busy working so I haven't been able to continue troubleshooting the phone (damn my patience), but Mondayish, I'll likely have traded my phone with a friend and root it and flash a new rom and see how the drain is with completely different hardware from a different vendor from a different lot of phones.
I had a similar issue with wifi. I changed the build.props wifi supliment scan from every 15 seconds to 180 and used the wifi fix manager apk. That seemed to help. Coupled with a proper battery calibration and I'm back to my display being the major battery draw.
So don't know if that helps but it seemed to work out my bugs.

This I can do right now.. and given I'm on the same, unmodified AR24 release, I can observe it for the weekend before I annoy my friend about his phone.
Seems the WiFi scan interval was already set to 100... moved it to 180 anyway.
I used to have this issue. I could literally see my battery draining while I was using it. I keep wifi on most of the time. I recently purchased an anker battery online. It is AMAZING! My old battery wouldn't last more than 6 hours or so. Right now I'm at about 14 hours on this charge, and I'm at 47 percent. Try swapping his battery for yours for a day or two. Another thing to try is different radios if you're losing power to cell standby.

The phone ran for 2days 9hours with WiFi off and lasts for 8-10 hours with WiFi on. I am pretty sure that it's not a Radio/RIL or a Battery capacity issue. ;(

My one s is not like it used to be

for a few weeks, my one s battery cant pass through 2-2.5 hours of screen time although it used to be something like 4 hours.
i tried to full reset, didnt help.
even noticed that games are lagging, like music hero and subway surfers to the point it can fail me.
most of the time the screen brighness set on 30%, wifi mostly off, gps off, sync off. only 3g is on.
i got s4 version running 2.21 software stock locked unrotted nothing.
as it is from the manufacture.
i dont use alot of apps, mostly basic ones like whatsapp chrome shazam and few more.
i dont think its some bad app which draning my batt, also the phone is 2 month old.
all this time, the phone didnt do any problems but 2 days ago for the first time after unlock the screen phone had restart.
could it be that after 2 months my battery is dying?
If you say that games are lagging there could be something draining your cpu... This could also explain the battery drain.
In the battery stats, what app/task is draining most?
Well, screen by far... No special app drains..

BetterBatteryStats and Carat. Take a BBS dump after a day's use and you should see what's causing major issues. Carat will take care of anything else after a few weeks by showing you what apps are using serious battery power.
it is unlikely that she dies. What radio are you using?

Why dont you install a Custom ROM for testing if this problem still shows up ? Like someone mentioned above something is fu*** up your CPU for some reason and this is the reason why your battery is going down very fast.
Some questions:
- Do you run any "battery saver" or any other app in the background (except Facebook,WhatsApp,GMail,..)
- Do you charge your battery from totally 0% (when your phone doesnt boot anymore) to full 100% ? It could be a battery de-calibration but this not really explains your lagging problems
i dont want a custom rom because i still want my warranty.
i dont run any battery saver app in background.
i charged the phone from 0 to 100 few weeks ago.
for 2 days im trying to be on gsm only and its seems battery have been improved by almost an hour.
there are less lags in games also and the device is feeling faster.
could be a radio problem?
i have full reception most of the time.
maybe the diztronic skin interrupting radio or something?
in few days carat will give me a report and ill see what he suggest.

I understand your argument but if you follow the guides step by step you will succeed. Even if you fail,you still have multiple ways to recover your phone. My broadband chip was broken and i lost my IMEI (Galaxy S1) and i had a custom ROM installed and the support still repaired it.
Maybe you need to calibrate your battery. If you only charged it once it doenst really helps.
Dont know,maybe it could be a radio problem.
You have a skin installed? If you rooted your device the warranty still could be gone.
i dont want to root the device cuz of warrenty.
i have diztronic case from amazon.
and i heared recharging the battery from 0-100 could harm your battery for long term and shorten the battery life.

No. I don't know where you got that from but It's crap. It doesn't harm your battery, in fact it is better than charging from 60%.
GSM only does NOT affect gameplay. Maybe battery, but not gameplay. Somehow I think you're trolling everyone.
Sent from my locked, tampered ville
im not trolling, i love this phone and really wondered maybe i did something wrong with it..
gsm only shouldnt affect games but maybe its affecting something else which affect games.
maybe its a software issue or drivers.
Guys, stop being idiotic. "Battery calibration" might as well be telling the person to charge the phone while hopping on one foot and rubbing his other.
It's quite simple. Post screenshots of the top of the list for partial wakelock, process, and kernel wakelock. This will help diagnose battery drain problems. Carat will slowly build a list of battery drainers that you can also use to identify issues.
And please make sure you're not using any task killers or similar apps as they cause more harm than good and are big no-no's on Android.
Speaking of Custom ROMs, I'm not sure what the rules are where you live, but where I live, unlocking the bootloader does not void the warranty, so flashing custom ROMs is perfectly safe, just make sure to make a backup first.
And yes, battery calibration is not possible, as these batteries doesn't have any "memory".
Where i live the warranty void sadly.
Im still waiting for carat report but for this moment, using gsm only + wifi instead of auto wcdma/gsm, seems to make my battery life normal - almost 4 hours screen time.

Battery life bad even on Anker 1900!!! Help!!

Hi all,
I brought my HTC Sensation z710e about 14 months ago, and I'm a pretty heavy user, so battery life took a hit.
After about 8-9 months i got 4-5 hours screen on time on the stock battery. About 7 hrs heavy usage. I tried formatting the phone, and kept an eye on battery abusive wake locks, but to no avail.
To rectify that I've tried various roms (Elegencia 4, VipersS 1.6, Albinomans CM 10.1) among a few and also tried undervolting the phone. Nothing.
Then about a month ago, I brought a 1900mAh Anker battery which according to a lot of XDA threads is the problem solver for all battery issues.
I've been using that battery with Albinomans rom, and I have tried wiping battery stats to ensure the battery starts from a clean slate, but still I get barely 7 hrs, far from the promised 2days.
That leads me to conclude that something is wrong with my setup. And having tried many roms and kernels, formatting my phone and doing most other stuff suggested on the XDA threads, I cant work out whats wrong.
If it is a hardware issue, is there any way of finding out what it is, and what would be the way to rectify.
Any help would be higly appreciated
(although I've been and rooting and playing around with my phone for abt 3months now, this is my first thread on XDA. It may be a little unorganised in the way its written. If i've left any info out plz let me know. Thanx)

With my stock battery, i'm about 20hours and more but if i play games for a long time it's normal that battery drops.
I even think that you can be happy that your battery takes 7 hours using it a lot.
Try these CPU settings :
Governor Lazy or Badass
Min : 384Mhz or 432Mhz
Max : uses frequencies between 932 to 1188Mh
When u change ROM try to wipe battery stats before first start
Before u change the Kernel, make a Full Kernel Reset. Flash new Kernel

This part all rings true. You cannot measure the battery life by how long you go between charges. That's almost irrelevant information because if ti's set up properly the phone will use very minimal battery when the screen is off.
The proper way to measure the battery life is by how much screen on time you get plus phone talk time between charges. With an Anker on Albino's CM10.1 ROM that should be 3 to 5 hours depending on a few other things. If that 3 to 5 hours happens all at once, then you'll need to recharge in 3 to 5 hours. If you use it sparingly over 2, 3, or ever 4 days before you've use it for a total of 3 to 5 hours, then it'll last that long between charges.
The 2 things that use the battery are the screen's backlight and the cell radio. Those two things are the battery users. Bluetooth and Wifi are too. But theoretically you're not using bluetooth or wifi unless you are talking on a call or having the screen on. So you can still measure by the scren on plus talk time. And if you use bluetooth and wifi a lot your total use will be closer to 3 hours than 5 hours.

This part is not true. It has no effect on anything. And when you install any ROM the battery stats are going to get wiped anyway because you are replacing the entire contents of the system directory.
No amount of wiping battery stats, calibrating batteries, or any of that mumbo jumbo is going to help. It's all snake oil.
Also keep in mind that you do need to give a new ROM 3 to 5 full charge and discharge cycles before you really see what the battery life is like. If you're jumping from ROM to ROM every day to test battery life you'll never get an honest look at what batter life is like on any of them.
Kernel
Thanx very much,
Any suggestions on what JB kernel to use??

On albino's ROM? You only have 2 options. The one that comes with it, which is perfectly fine. Or SultanKernel, which isn't terribly different. But the install process of sultan gives you more configuration options.

[Q] Heavy battery drain issue - help troubleshoot

Of late, I have been having heavy drain of battery on my Atrix 2. I am running JB 4.1.2 (672.300.404.ME865.Retail.en.05). Trying to troubleshoot it (including recalibration) since the last few days without luck.
The symptoms...
- Sudden shut down - Have had 50%+ charge levels. Goes down to 5% and shuts down within minutes. (You can see the random drops in the charge levels in the pic)
- Completely drained out battery charges from above 40% when plugged in & charges to 100% in no time. (that 67% charge in the attachment is within 5 mimutes of power plug in)
Does the battery need a replacement?

Try changing battery... even i had same problem with Custom rom. Battery used to last only for 10 to 12 hours but now its more than 17 hours on JB 4.1.2 leak,,,,...Use stock rom. and remove any unncessesary apps and installl ROM again if u want :good:
How old is your Atrix 2? If over a year then battery surely begins to give lesser performance. Disable any other task killer / memory manager & just let OS do its thing. See if installing Media Scan disable from play helps & do not keep using random chargers, make use of original charger as received with phone. Finally see Better Battery Stats. It is said battery stats should never be wiped but see if it helps you and finally search for Apex's better battery life guide for many handy tips.
I disabled notifications, sync, froze higher wakelock apps & my battery life improved a bit but then it is no fun existing in a bare bones environment.

The phone is just about a year and half old. The drop in battery performance is just too drastic, sometimes it doesn't even last an hour after the charge. Will try to go back to original ROM and see if it improves else will probably have to go for a new battery pack.

Look like a battery problem to me its not the ROM but anyways turn off location services and wifi they are a big battery drainer
Use 2G when u dont need high speed.......
Try this app called Greenify https://play.google.com/store/apps/details?id=com.oasisfeng.greenify
(it helps to reduce wakelocks and improves your battery life)
:laugh: Let me know if it helped (btw chck your battery and see if its defected they are amny ways to chck it read up the forums )
i have the same problem whit any rom of 4.2. when the custom rom shows 5% i change to stock ics rom an that show me 45%

Think mine is clearly a battery issue. Replaced the battery with a new one yesterday and now the phone lasts 6 hrs at least on a single charge.
CM 10.1.3
I couldn't write to developer's forum so I'm asking here.
I've recently firmwared my AT&T A2 CM 10.1.3 and battery drains really fast! The previous build was CM 10.1 (25th of June). I wiped cache and dalvik cache and firmwared CM 10.1.3. At least 3 people report that thie batteries on this ROM drain slow.
What did I do wrong???

Battery life varies so much from user to user that it is impossible to answer your question without A LOT more information.
Go here:
http://forum.xda-developers.com/showthread.php?t=1179809
Download the app and follow the directions in the op. That and reading through that thread itself should tell you everything you need to know about what is using up your battery.
That being said, everyone has different habits and expectations when it comes to their battery. What one person says is good battery life, another will likely say is bad. So just keep in mind that there is not a right or wrong, just what is right or wrong for you.
If I had a dollar for every time I said that, I'd be making money in a very weird way.
Thank you fro your answer. When I used previous version of CM the battery lasted 3 days with minimal using and turning the flight mode at night on.
As long as I installed newer version with JBX kernel the battery lasts 20 hrs max.

[Completed] Massive battery drain for Samsung S3 - tried most solutions on the web

Dear XDA experts,
It seems I have a typical problem for most Samsung Galaxy S3 I9300 users. I've been testing my phone's battery capacity on two different batteries, and four custom roms, yet something leeches out their power incredibly fast.
I've been deeply investigating the issue across the web, with no prevalent solutions that worked. Below I will describe exactly what my problem is, my specs, and what I've done to this point.
This will be my first post. I'm only doing this because I want to bring BetterBatteryStats data into consideration, without just speculating "do this". Please have mercy on my soul - I really appreciate all the stuff on the forum, and I wouldn't like to violate any rules.
Problem
My Samsung Galaxy S3 I9300 drains my batteries as a vampire, regardless of what I've tried. Just to give you an example: the phone loses 6% out of a 100% in just 40 minutes of standby, while being optimized, with no "lost signal" search processes. Without charging it twice a day, the S3 remains mostly unusable.
Purchase and Specs
I'm its second owner. The previous one sold it to me through an auction site (he was changing to S4). The phone seems legit. Mint conditions, little or no scratches visible. The system was factory wiped, and later it turned out that it wasn't flashed before. I also got original Polish carrier boxing with instructions, and equipment.
Note: The guy didn't handle the receipt to me, and I don't know if there's still warranty on the phone. Servicing might not be an option.
System:
[Cannot upload - all files in a MediaFire folder. Please look over there. Just add the missing characters]
www (dot)mediafire(dot)com(slash)folder(slash)wfb1spe9ez9al(slash)xda_S3_thread
SentinelROM 6.00
3.0.64-CM-gfab9e4c Kernel
Android 4.4.2
Factory battery EB-L1G6LLU 2100 mAh
Second battery M-Life ML0373 2300 mAh 8.5Wh 3.7v Li-ion
Normally, Bluelight Filter and GoLauncher EX Prime are the minimum that I have in the background.
What I've already done
Rooted my S3 with CM Autoroot
Installed CWM Recovery 6.0.4.6
Always did a factory, cache, and dalvik wipe
Tested CM11 NIghtly from 09.12.14
Tested CM10.2 Stable
Finally flashed SentinelROM 6.00 4.4 KK
Debloated my phone - not syncing, no tracking
Disabled "All, that's Google" #notonmywatch
With every new ROM, I've been optimizing settings and tweaking the CPU to ONDEMAND. Also, same time I've been running Go Power Master and Greenify. That covers nearly everything people were recommending in the many threads I've visited.
Weird facts
Phone can lose 6% in 40 minutes after charge while idle
Writing an sms can take as much as 10% of the battery
It seems odd that the S3 can fully charge in just 1h on both batteries
When trying to discharge my phone, it deadlocks below 4%, lasting unusual 2.5h when used
Screens
I've been monitoring my phone for a day with BetterBatteryStats while I had Greenify hybernate some apps. Obviously, I've seen an improvement in the performance, but it just seems not right. There's a lot of pics here, but I hope that someone can spot a tracing app, or some other spying tactics, because I just can't explain what's on.

www (dot)mediafire(dot)com(slash)folder(slash)wfb1spe9ez9al(slash)xda_S3_thread
That's all I have for now. I think it would be a great favor to everybody on XDA to finally crack the case. I'm open to suggestions, and I can run tests on the S3 and provide results here.
Last question
Could someone recommend the best ROM and kernel for energy optimization?
Thank you, and good luck.
PS: Imagine playing Watchdogs with Aiden having an advanced S3 phone... Wouldn't happen
Your symptoms sound like bad batteries honestly. The biggest giveaway here is that the battery drains ridiculously fast to 4% then lasts the "normal" amount of time. This is usually indicative of dead cells.
My suggestion, buy another battery, avoid the cheap aftermarket batteries, either go stock or a good quality 3rd party battery and see if it changes anything.
How long between flashes are you allowing your device to settle? Battery drain may appear high on fresh flashes for the first few cycles, this could also contribute to what you're seeing.

Hello Stryke,
Did you had a chance to look through the screenshots? I might buy a legit Samsung battery, but just something tells me that could not work. I've already seen posts from people saying they tried replacing the battery with another original, but without luck.
I must admit that I didn't consider the time in between flashes as important (never heard about it previously). Normally, I would just copy my zips to SD, reboot to recovery, do a wipe and then flash.
Please tell me - what do you think about the charge time? Is 1 hour enough for a full charge?
I welcome any other suggestions!

Generally no, even with fast charge my note takes longer than 1 hour to fully charge. I'd try the new battery, that will at least rule out one possibility. Time between flashes can make a huge difference as well, especially if custom kernels are involved.
