So im using tbaldens cm9 and set the CPU to performance, which sets CPU at 1400 constant. So I was playing temple run for about 10 minutes and my battery temp got up to 50 degrees. I have a program called Droid system suite and it said my battery was overheating at that temp. My question is, what is a safe temp for the battery? And how long should that temp be maintained? Thanks advance.

to be safe don't let your battery temperature exceed above 50 c
below that temp its safe

So would it be OK to sit at 50 c for periods of say 30 minutes? It gets bloody hot to touch

As lithium battery exceeds their operating temperature regulary, it will impact on it's life. While working on overheating state, it may not able to provide stable/enough currents to the phone. Wrost case scenario == blow (ignore, this need really hot).

well i would say if temp reaches 50 c then leave ur phone for some time as it will affect battery life and also don't use ur phone while charging until the battery is charged more than 50% as many times while playing games at charging less than 50% our phone consumes more power than the power it is receiving

It gets to 50 c after only 10 minutes of game time. So you think 50 c for battery is too high? Should I stop gaming if it gets to 50? Don't really care if it uses heaps of battery, just don't want to damage it. Lol.

which game are you playing? i have played many games and none take me to 50 c in 10 minutes
may be u can try faux kernel to reduce battery temperature and which rom are u ysing?

As most of the smartphones now use LiPo battery, so here is a safety guide:
http://www.icharger.co.nz/articles/ArticleId/3/Lipo-Lithium-Battery-Safety-Guide.aspx
Wowza!!! That's hot!
All good, took it off performance mode and set the minimum speed to 475, seems to be not getting as hot now, where as I had it set to 1400 all the time and it would get really hot...

htc released a statement near to when the hox was released. it said that 55 celcius was normal and safe.
Yea mine is running under that most of the time on CM10 ROM. Playing 3D intensive games like Dead Trigger. Does get hot after quite sometime but not 10min. Good thinking with the CPU Speed adjustment, i used an overclocked kernel for a short bit @1.7GHz but that got pretty hot pretty fast so I have left that for now. Don't really need it on a quad core. Yet.

Something Ive always wondered, what is an "AVERAGE" battery temperature for cell phones? I ask because im using setcpu and i never knew the temp. to start getting concerned . Right now it is 87.6 degrees with the low clock at 1ghz on demand at all times.

That is normal temperature. Once you use the phone (play games, internet, etc) it will reach around 90-100 degrees.

There are several different applications on the android market which will tell you the temperature of your battery in Celsius and Fahrenheit. That is about average temp, I have two phones sitting next to me right now and they are both in the mid 80's range on the temp. You want to be concerned if your battery reaches temperatures exceeding 101 degrees (Fahrenheit) (38 Degrees Celsius) when doing any activity and especially if it is getting that hot while sitting in standby.
I've had a recent problem with mine the other day I was having a really bad battery drain and the battery was over heating bad(im talking 105 degrees) since then I was able to fix what was draining the battery but I noticed when I use only my car charger (which was meant fire my vibrant) it heats up. I'm thinking the car charger voltage is different.

the highest mine ever got was 56C
i could have probably fried an egg with that
Mine stays around 82 while screen off. On and playing games it got up to 110.
I`m not playing games or running CPU demanding apps, just phone calls/sms/bit of non flash web.
Is it possible to downclock CPU to increase usage(save battery)?
Or CPU doesn`t eat that much battery and downclocking would have very little effect on battery?
With a rooted device, you might want to try CPU Master Free. You will be able to decrease the clock speed.
Also, you could try to UnderVolt your CPU. Search for your phone model UV in te forums.
Min frequency is 350MHz so if your not doing anything it will be idling at 350mhz

It does help you save precious battery life.
You can download the best app for overclock, SetCpu, from the XDA site, it's free for XDA members:
http://forum.xda-developers.com/showthread.php?t=505419
How much more battery life I could get by downclocking CPU? Any feedback from people who have tried such thing?
On my gn i find the screen to be the biggest user of thr battery power so underclocking prob would have little use, ohh and iirc the phone uses race to idle which procesess overything as fast as possible to get the cpu back it low power idle state.

I normally charge my phone before go to sleep, I don't overcharging it during the night.
My SetCpu frequencies are Min 19/ 692 Max.
I am connected through 3G data ALL day and I am always online on Skype, I use my phone a lot, browsing, games, and phone call, and I can tell you, thanks to the undervolting, I got home at night with 50% juice remaining.
Without SetCpu, I would have 10/15% left at night...
yukinok25, that`s huge improvement, I`ll try it definitely.

Remember that battery life also depends on Radio version and kernel installed.

If you mean after you just bought it, Its enough to let it fully discharge twice, without charging it, in between this two circles.
Anyway with nowdays Li-ion battery, you won't really need to this so anymore, since the lifespan of battery start to decrease from the moment that they left the production factory.

hey guys is it normal that our W heats up to about i think 45-50 degrees while charging.. sometimes it heats up too when using the internet via reverse tethering.. just wanna know if its normal, and some advices to prevent it would be awesome.
With Black Notes Hybrid 2nd Gen
Its happening to me aswell getting really hot.
I recently flashed to BlackNotes Rom and when i was charging it overnight for the first time,when i woke up i picked up my phone i immediatly dropped it.
i checked on set cpu the speed was min122 max 1401 ondemand.
ALSO i checked the temp it WAS 60c literally i swear phones should never go over 50c.On stock rom the highest i was every on was 45c playing games.
From then my phone always gets hot with 1401mhz. i dont know why.
With normal use average temp 31c-35c it used to be 27c stock ROM.
I think i sholud get a new battery because 60c is rediculous that could explode it and i thought li-ion batterys have fail safe or something like that for 50c???
EDIT: setCpu 122min 768max and my battery is still 36c im not playing any games im just on homescreen.

WOW. WOW. 60c is too far hot! and yes your phone and motherboard can be burned! When I using BN chapter 2, and when playing games (1401 mhz) the temperature never above 42c, and then I limit the cpu, it will automatically set the cpu speed 245-368 with powersave governor, and screenoff with the same configuration. so when idle, my phone never above 25c (im using arco CM9 now). and I suggesting you to buy a new battery
my phone heat up too,but about 40C only
I've been on the Bionic cow rom for the last few days with data enabled, anyway went to send 4 1.1mb pictures to another email address today and as well as taking around 10-15 mins (2G) it got really got like through my trousers it was making my leg quite hot but never seem'd to get that on original rom
Jamie.
just an addition to my post. i live in the philippines where the temperature is getting really hot this few days. i tried to charge my phone on the office where its about a bit cold and the phone never heated up. are you guys from a cold place and still heats up? if thats the case then my problem is just normal.
maybe you can try download cpu spy from play store and check your cpu time in state. now i'm using bionic cow rom with xxlm8 kernel, the cpu time in state is always 1401 mhz. it's fast but create heat when playing games n surfing!!! i've attach my device screen shot as reference.

sure ill try that app.. my phone heats up too now when im surving using droidvpn.
i found an app that displays the current temperature but only for the battery, i dunno if only the battery heats up and not the phone.. the attached screenshot was the normal temperature of my phone, ill try to upload another once i got time for hard gaming or browsing that can heat up the phone, maybe on weekend.
My phone usually goes up till 4OC. But thats when I use data network and watching movies on the web at the same time. When charging my phone heats up to 35C. Other than that I cant think of any other ways how my phone heats up. But will let you guys know when something comes up.

does your phone heats up while your using it? or just on charging? mine only heats up while charging so i only charge on the office to maintain the temperature, its better to charge on cold places, however if your phone heats up while you are using it then maybe its because of some tweaking that you've done to your phone thats makes it use too much CPU that causes the heat.
normally i play some hd games mostly bcz of games my phones heat up.does it happen to anyone too while playing games phone heat up.if i overclock my cpu and reduce the frequency @ 1.2 or 1.0 mhz i think then my phone heat less

i also play HD games and watch movies, but my phone only heats up when im using reverse tethering(means i use internet on my phone via usb from PC internet) and i think it will really cause heat because of internet and the same time charging while connected in the USB, maybe you made some more adjustments that made your phone heat easily. but if you play for hours then its normal, just for me don't play that much long or less your internal chips will melt.
I just got out of the shower and grabbed my phone, to have it literally burn me. The hottest I've ever seen it get (while still on) was 180°F and this was way hotter, I'd guess around 250°F. Why is this? It was charging, not over clocked at the time, limited to 2 background processes, and the app "reddit is fun" was the only thing open.
Phones in the freezer at the moment, so I can only hope it and the battery didn't suffer any internal damage. Wheres the thermal cut off? (That was not disabled in Franco.kernel settings)

First you are going to need to tell us what you have modified to the phone. Also remove it from the freezer as this thermal shock can cause more damage. simply remove the battery from it. is this a stock battery? did you turn on fast charge?4was this under your pillow while it was charging? etc etc. we need more information to properly help you. and was this battery temp that you measured or cpu core temp?

Running CM10, Franco kernel. Battery is stock, no fast charge. It was slightly under the pillow (but it always is, this is the first time I had this problem since I got it in February). I didn't measure the temp (phone wouldn't even go on so I just pulled the battery before it got any hotter), its just an estimate because I know it was above 180°F.

Cells are storage tested at 65C and charge temps can reach higher than that. I wouldnt have a panic attack over this instance but the next time you charge it, monitor it with a battery app that displays battery temperature. Your battery could be going bad.

Download System Panel from the Play Store and monitor your CPU activity and active apps. I've had rouge apps churn my processors @100% before. It's a sure fire way to generate heat!

I don't really know the tolerances, but from personal experience of groping various phones, I'd say no more than 50C internally, no more than 40-45C on the case.
Why don't you just Google this, my man?!
I get worried when I see my temps over 35C! The highest I've seen fast charging while intense gaming was 38C!!!
Should limit fast charging ovet 40C, 1/2C charge rate over 45C stop charging <55C - 60C

... that just tell me my note 7 i had would have exploded eventually I know with just fast charging i know it went past 50c and bluray video went to 70-80c till it regulated it self after few video to 50-60c.
Still I say any hardware should be 30-50 at best 30-40 idle. High usage i say 60-75ish... but anything over 80c you need large concern as that not even a good temp for computer that often.
Batt temp: 30-40
CPU temp : 38-60
Quite good but will do replacement in next 2 weeks
