battery overheating

hi guys..just got SGS2 and I have battery overheating problem, I saw a lot links on google with that problem but could not find solution...is there a soultion for this kinda big problem?

It's not the battery..it's the phone and processor overheating, working nonstop due to constant updates of apps, searching for signal and so on. It's like a car revved up on traffic.
Try to find out what's actually running on the phone, you can start by reading battery related threads.

thank you for your quick tip...for example, all apps are down, i only use browser and after 10 min it is so hot...so there is no any custom rom here that reduces this heat a bit??? seems little bit to much

There has to be something running in the background..could be apps updating, or phone searching for signal(especially if you have wrong modem installed).
I personally check Every apps I installed, and make sure they don't do auto update. Quick check, try to turn off background data, and then auto sync (both in setting). See what happened.

To my experience
Using wifi with low signal can caused significant battery heat.

Are you using the phone while it's charging, that tends to heat it also

Relax, there is nothing wrong with your phone. If you play a game or browse flash powered sites, you can cook eggs on the back of your S2! Talk about multitasking phones, who else can cook you breakfast?
Personally, I reduced drastically the heat/power consumption by rooting the phone and removing over 60mb of crap. Now I run at 160mb of memory for services and my battery life easily doubled. It still heats when I charge it for a while... On my old Palm Pre2, after 2hrs of usage my battery was completely drained with similar heat issues.

That is a lot of wakelocks that maps is giving you there man!

Thanks, never thought about it... How do I fix this?

First: HOW HOT is Your hot ? (for an Eskimo 15 °C is already very hot)
Second: Leave it as it is. EVERY ELECTRICAL DEVICE gets hot when used. The more the hotter.
E.g. Laptop core i7 CPUs are designed for max. Heat of 105° C and my Vaio runs at 85°C when CPU is at 100%.

I'm gunna guess........ Latitude? Do you have this enabled? It depends on what you are trying to do, about 25% battery in 5 hours running time isn't too bad or anything, just all of those waking events add up. Also it could be that you are out and about and that your WiFi is constantly searching, that would be my other guess. But maps has already admitted to eating 21% of your charge on your third screenshot

Ya, latitude is on.

[Q] Nexus 4 battering keeps discharging and recharging while plugged in

Hi everyone,
I searched the forum for a satisfactory answer yet I don't seem to find one so I'm going to ask here...
I have the habit of plugging my Nexus 4 as soon as I get home, keep it plugged overnight, and unplug it the next day when going to work. About two weeks ago I noticed that occasionally the phone indicates that the phone is fully charged yet, some minutes afterwards it indicates that the battery is at 98-99% and is charging again. I was quite intrigued so I started using some battery applications (e.g. Battery Widget Reborn) and I now notice that the "problem" is quite frequent and happens every single time the phone is plugged (I tried withe the original USB cable that came with the phone as well as with other cables). Attached is an image showing the weird pattern that I'm having...
Does any one have the same problem ? Anyone cares to explain to me why this is happening ???

Isn't that done on purpose? You don't want to keep charging at 100% so the phone discharges after reaching 100% for a while.

When 100% is reached, the battery, for the best of my knowledge, is not used... Therefore, I find that it discharges very very quickly for an unused battery !

Mine does that as well. I thought that was normal?

It's Normal as phone batteries reach 100, discharge a bit and stays there. Btw ROM + Kernel?

Just stock Android 4.2.2

How quickly it uses that small amount of battery that kicks it back into charge mode is going to depend on what you have running and syncing in the background.

Battery life sucks

2 hours on the phone did this to my battery. Screen time was 48 mins. Screen was off on call using BT. Phone was red hot after call

It is something you installed or something on your setting up the phone.
this phone battery is amazing , trust me it is.
I get screen on times , unthinkable to my previous phones with brightness way way higher
so.. just try to figure out what is eating your batt and why.
edit:
then again you didnt start your battery log with 100% batt
and your drain was due to a very phone cal (?) With screen off, but your network signal suck really bad, maybe is from there ? But even with low coverage I find it hard to imagine that drain.
But then again.. never had low coverage ..

Yeah I can assure you it's something in your settings that is giving you poor life. You didn't give much description of what they are so it's tough for me to help you with what to fix, or how much knowledge you already have. I recommend BetterBatteryStats and Battery Mix for starters.

Install BBS (Better Battery Stats) and find the rogue application that is causing battery drain.
Battery life for me is amazing. I get close to 28-30 hours with mid - heavy usage.

Your signal during this two hour call was awful. Keeping a connection while not using the phone is a battery sucker in these conditions. I imagine it is much more so when you are actually on the phone. I'd suspect that as the culprit, as the radio has to be pumped up to the max constantly, instead of every minute or so.

I had a note 2 on same network and never saw this kind of drain. I think this qualcomm chip is ****. In my settings my cpu was at 2.27ghz for 1 hour 43 mins! Why was my cpu maxed out while making a simple call.?

[Q] Is this normal battery drain?

Ok guys, I keep hearing people ranting and raving about this phone's battery, however I feel that mine is either faulty or everyone else is exaggerating. On a typical day, of normal usage, heavy web browsing, occasional 10 minute game session, I can get about 4 hours screen on time, and about 14 hours total time before it's dead and I need to charge. I have minimal wake-locks now that I've figured the majority of them out, and keep location services on device sensor only. My device is deep sleeping more than being awake, and will last quite a while while asleep, battery doesn't seem to abnormally drain while asleep. Every time I've been able to track it down to a wake-lock issue if it has.
It's draining very fast (it seems) while screen is on though. Wifi calling is almost always on the majority of the time.
Any ideas? Is this way off? Or is this the norm?
I've done the usual factory restores and all that, and still no improvement.
Thanks!
Example:

Are you using a custom kernel? You could try dorimanx's and heavily skew the CPU towards a lighter load
I used to get 4h on screen time for quite a while, but k realised that it was cos of 4G @ and the way I used my phone. If you read a lot and hardly launch or close anything the battery life gets better very quickly

That seems about right.
On stock I get between 4 and 6 hours screen time and about 24 hours on battery. Being on WiFi rather than 3g helps a lot and turning down the screen brightness.

Do you guys have similar averages? (Seen at bottom of image)

Is battery life getting better over time?

When I first used the OPT, I noticed that it loses battery *in standby* pretty fast. Screen on time was good but just leaving it be would drain a lot of battery. I turned off LTE but also noticed that it often struggled with cell network quality (which usually makes a phone look for other stations etc. thus battery is used a lot).
However, today, after a couple of days of use and maybe 3, 4 recharge cycles, it seems a bit better. Is there a chance that this is an actual effect (it could be something very different). Do batteries also get better after some use or am I just biasing my highly non-scientific measurements here?

I've noticed this too. I think that this battery technology does improve its capacity after several charge/discharge cycles.

Correct but what about 100+ cycles... It start loosing its power.... What's the best way to keep a li-ion unit last longer? Any help or suggestions?

Good practice is not let battery overheat, like when you play and charge, also batteries don't like to be fully discharged try to keep at least 20% and start charging again

Short answer. No, worse.
