/Q/ CPU damaged? - Galaxy S II Q&A, Help & Troubleshooting

Hey,
I'm using my S2 with CM10.1, and sometimes I have redraws when sweeping through pages in Trebuchet, and when I play games like Zombie Highway I have FPS drops sometimes. I never have used my device with overclocking or undervolting. Just one time used Siyah kernel with higher GPU freqs. Is there a chance that my CPU is damaged or bad? Btw I'm experiencing huge battery drain, but I'm using extended Samsung's battery with 2000mAh. I have taken that battery back to shop, because thought it was wrong, they replaced it to brand new, and the problem is the same. I'm surfing in internet with my S2 switched to 2G network and after 10minutes of surfing I see 5% battery came down... Usualy I charge it two times per day, which is very annoying. My screen brightness is 40%. What's the problem? If this problem will be in future I will probably switch to iPhone.

battery use stats?

Here it is.

Are you on the latest nightly? If you are and you do face the problem, make a backup and return to stock ROM to check if the problem persists. There have been a few complaints regarding games in the official discussion thread, but should be fixed soon.

[Q] Draw Something = Huge Battery Drain

Any Draw Something users having the same problem as myself?
Currently on Hydrog3n rom but I have tried others. Usually charge my phone via laptop but when playing Draw Something phone still discharges faster than its charging.
I haven't noticed any battery drain while playing that on my sgs2 running cm9

Doesn't affect my battery whatsoever. Must be your phone buddy.

On CM9 it cause a huge battery drain here too. If I use it I loose close to 1% per minute
Using sensation rom no batt drain at all
Mod or Die
change kernel.
speedmod look the best
htc hd2, hyperdroid (fikret) - i'm also experiencing a huge battery drain when playing draw something :/
Am also on CM9 with Nexus One (BCM ICS). Draw something is indeed drawing lots of battery power. Phone gets immensely hot. Running the Tiamat kernel from March 14
No battery drain on neat ROM

How fast does your drain I play draw something alot, I don't seem to notice it to drain that fast.
I have the same issue here with a LG optimus 2x, draw something consumes all the battery in 2 hours or less. (with stock rom)
Try Different Kernel
Speedmod, Siya or NEAK

Cpu overheating constantly

Lately I've been having major issues with my processor getting extremely hot. It only warms up when the screen is on. Normally I wouldn't care but it gets hot enough I can barely touch the screen (over 100° F) and results in major battery drain (battery drain doesn't bother me because in using it, but it still seems too high). Does anyone know a few tips or tricks to keep the temp down? Currently I'm running on AOKP and have the default kernel but I also experience the issue with siyah kernel as well. Thanks I will advance B-)

More likely than not you probably have some kind of rogue app running in the background, but without any more information, that's all I can tell you. Try installing BetterBatteryStats for wakelocks, or tell us what apps you have installed, or a screenshot of what's draining your battery.
Did u full wipe before installing the Rom? If not, there's no reason to post this issue until u have. If u already have, then as stated above,u need to find which app is causing the problem. Definitely not a Rom problem, just an fyi for others who may read this.

I also have been having problems with my cpu overheating. And my screen does not want to turn back on and phone reboots into safe mode. And will randomly turn on and off. Any one has any ideal what could be causing it, and is it bad for your phone to go into safe mode.
Sent from my SAMSUNG-SGH-I777 using xda premium
No it's not bad for your phone to go into safe mode, but once again, please provide more details!
It's definitely not because I did not wipe... However I will check out better battery stats I didn't think it would be an app causing the over heating because as I said it only occurs when the screen is on. I was thinking it would be more kernel related (voltage levels or governor related). Thanks tho I'll report back with battery stats

I thought getting hot with AOKP was just par for the course, like the weird keyboard bug.
Mine gets pretty hot all the time, with normal use. I full wipe each update, most recently when installing the update on 7/3. I use Fluxxi kernel as is with no oc or voltage changes. Its hot while using wifi or data, and battery life seems normal.
Over the last 13 hours I have 3% time above 800 MHz, 35 seconds of wake lock for network location.

Galaxy S2 bad battery life on every rom (even stock)

Hi,
I've been flashing roms onto my phone for months now and what I've realised is that the battery life is always awful. I hardly ever get past 10 hours, with just 1 hour of screen on time as my battery drains in stand by. I've tried cm7, cm9, perfect galaxy, miui, stock and many more, but my battery life always seems to be the same. Currently I'm running cmiui (latest version) and still battery is draining very fast. I read about people having amazing battery life on a daily basis.
My current battery life drains by 1% every 2-3 minutes of screen on time and about 5% of drain when in deep sleep or stand by an hour, sometimes even more. I use betterbatterystats, cpuspy and gsapp to monitor my battery but nothing suspicious occurs. Usually my 'awake' time tends to be 50% higher than my screen on time according to betterbatterystats, however all the wake locks tend to be kernel related. Changing kernel doesn't change this either. I've literally tried everything, installing several kernels, modems and calibrating my battery every time I flash a new rom.
Also what I realised is that my phone frequently overheats near the camera and even sometimes reaches 50°c.
I would appreciate it if anyone could help me on this topic. It is really frustrating that I cannot get through a day of even light use of my phone, which makes it almost unusable as I'm always concerned about my battery. I've also tried several batteries, so the problem doesn't lie with the battery.

Everytime you install a new Rom/Kernel you have to wait for it to settle down (About 2 Charging cycles). If I flash a new Rom to my device Batterydrain is very high too at the beginning. What you can do is install a Rom and a kernel which supports undervolting and underclocking.
I use Resurrection Remix ICS 2.6.1 with the Siyah 3.5.2 Kernel with this Voltage/Clock settings (LESS AGGRESSIVE UV VALUES with -50mv and not -75mv undervolting):
http://forum.xda-developers.com/showpost.php?p=26755476&postcount=850
With this settings I get 16 - 18 hours easily and with about 2 1/2 -3 1/2 hours of screentime and also about over 4 hours of listening music and doing other stuff of course.
Everytime you undervolt/underclock make a Nandroid backup!
Thanks, I've heard about the battery charging cycle before, I'm new to cmiui, flashed it yesterday but I've had cm9 on for about two months and the battery life was horrendous. I will try the undervolting and see how that goes

Strange, I am on stock and can make almost whole day with 3-4h screen time. Sounds like some issue either with battery or with the phone.

get a 2000 mha battery over ebay
I have been used 2000mah battery, miui 2.8.3 + siyah 4.0.1 kernel, no serious battery life issue :good:
I have a 1800mah battery, its actually not that much better than the stock battery, but doesn't the 2000mah add extra thickness?

Yes but it`s no thicker than your speaker part of the phone.
I'll have a look at it, I've re calibrated my battery this morning and ismt half bad so far. Its 9 o clock now and sill have 38% left with about 1.5h of screen on time, phones been unplugged for about 10 hours. I've used the undervolt setting as suggested but still loose about 4% of battery in stand by each hour. On comparison my mums iPhone 3gs looses about 1% every 3 hours. Surely the android battery isn't that much worse

If it occurs with every rom you have could it be app related, wiggets or syncing too frequently?
Sent from my GT-I9100 using xda premium
That's what I thought but I've analysed my apps with betterbatterystats and gsapp, nothing suspicious came up and wakelocks are always kernel related. I've tried several kernels as well

Get cpu spy from the play store to see if your device is deep sleeping. Also, you can try 1900mah anker battery. I got two and a charger off eBay for $25 can. Definitely a good deal
Sent from my Nexus 7 using xda premium
Mysterious indeed, all I can suggest is what I would try which is to give a custom rom call slim rom a go after full wipes and format system. Its a stripped down rom and always gives good battery life as it's so lean. Hope you find a fix soon all the best.
Sent from my GT-I9100 using xda premium
maybe your battery is bad i bought a great 2500mah battery on ebay http://www.ebay.com/itm/2500mAh-Ext...ccessories&hash=item4ab6494de0#ht_2481wt_1163
that combined with the rom OLLO MONSTER gives me awesome battery life
I might have to invest in a new battery. As I said before I've upgraded to a 1800mah battery and using that but the difference is minimal. Also I have CPU spy and it goes into deep sleep quite a bit, awake time however according to betterbatteystats tends to be about 30-40% higher than screen on time. And i'll try the suggested rom after I've given this one a few more days on the undervolting

For BBS, anything over 1% is something that needs to be fixed. Keep in mind you need a good sample time (like over 5hrs)

Hmm looks normal, I would get the 2000 mah Samsung Original Battery because 10 hours and already on 38% battery is not so good in my opinion.

I've taken a few screenshots of bbs, somehow the kernel wake lock is completely empty which is odd
Also I only need the battery to last about 15h with 3-4h of screen on time to get me through the day!

the same problem happened to me too what worked for me was that i took out the battery and reinserted it and i also change the charging mah to 1200 (i'm also using siyah kernel)
This is not a problem just for you. This is normal..
Just don't play heavy CPU and GPU usage games while you charging.
Changing mah is risky a bit. You warned..

Definitely agreeing with oulouloul on this one ay, Changing your mah can result in over heating your battery and damaging your phone,
Is there a option in the game to turn down graphics maybe?
i normally look for that just to save some battery anyway
interesting. it never happened on my sensation when playing GTA3. i guess the quadcore is too powerful

Help battery charge very slow

Well here is a problem with my battery, the thing is that my battery charges slower world what I talk about that is loaded in 12 hours or more, but that if I can not play because you are lowering the percentages just see it, I did the battery calibration and wait to be charged at 100% and nothing happened after I see the same, I read that was to change both roms, must be that these last two months I've changed like 3 times rom (paranoid, softmax, and again by the holo paranoid) then let me know if software problem or I have to buy another battery?
Or cable? Did you do a search? There are loads of threads on this issue and they all pretty much contain the answers

I'm wondering if anyone can help me out with a similar issue (wife's phone). I'm fairly certain it's not a cable issue; here's why:
I've tested with multiple cables and the issue persists. I decided to test her charger with my Galaxy Nexus and found charging was fine. I also loaded up Battery Monitor Widget on both phones and saw a huge difference. Her phone charges at 281 amps, mine charges at 685 amps. My phone runs CM 10.1, hers runs stock. FastCharge is NOT enabled on my G-Nex.
Her battery drains stupid fast. Faster than mine, and the G-Nex is not known for having a great battery, while I've generally read good things about the S3's battery.
So based on the 2 items above, I'm leaning towards an app or something that is draining battery (she installs all sorts of crap... she isn't tech savvy; but at least it's all from the Play Store). They're getting the same power from the same cable/charge (in theory), so I'm thinking an app is using the CPU preventing a faster charge. I can't seem to locate the app that's doing it. I also notice she's using a ton of data; with the Up/Down arrows flashing constantly, so I'm thinking maybe something is constantly accessing the network, but again I can't find it.
Reading battery stats doesn't seem to help since they all show the screen is the source of the battery drain. If the screen is off for the majority of the time, it wouldn't be caused by the screen, right?
So does anyone have any idea what could cause this or how I could find what app is killing network or cpu?
