Hi,
we already have an "overheating" thread. i'm interested solely in battery temperatures that people are seeing here please.
I'm seeing upper thirties browsing, in low 40s when installing large apps, gaming, camera etc.
a 4k video recording got to 47 degrees!
seems far too hot for my liking! what are others seeing?
Edit: I confused the subject.
hi. thanks for the reply but I am sure you are confusing cpu/soc temperature and battery temperature. a lithium battery at 65c would be at risk of explosion!
Sorry, you're right. I confused the subject. [emoji16]
I'm interested in this too. Because I'd like to increase the kernel speed (something less conservative) without risking the battery.

Im not sure if this is normal but the cpu temperature after like 5 mins of use always goes up to 30 degrees is this normal? I'm not overclocking and not doign much but you can feel that the battery gets real warm...
Do you guys experience the same?
CPU temperature of what device?
30C is low or normal for most PCs, and though I am not sure about mobile devices in some parts of the world it is room temperature this time of year.
For a better (more specific) answer please write what device you are measuring the temperature for and what software you are using to do it.
P.S.
The feel of the battery has nothing to do with CPU temperature. They often get warm specially while charging.
On my prophet, if I charge it, OC it and use all the radios (Bluetooth,wifi) and do processor intensive stuff like watching a video, battery status tells me it's at about 40... I haven't noticed any damage, but I only do things like this very occasionally. I don't think it should be a problem although if the battery gets too hot it will degrade.
allright im using htc p4350 Herald and I'm measuring with battery status pro...
But it might just be fine if l3v5y says somethin about 40 degrees...
I would try and keep the temp down as it will last longer running cooler, but I don't think it will impact too heavily.
Hi.
While playing games my Xperia Play produces lots of heat. The back of the phone, and the gamepad feels really warm.
I checked the temperature with Battery Monitor Widget and when I don't use the phone it stays around 25-30 degrees Celsius, but when I play games (even 2D ones) it goes up to 38-40.
Is this a normal thing or there's something wrong with my battery ?

I can confirm this happens. Basically it is using more charge, therefore as a side effect of that it produces more heat from the chemical reaction. Same thing when you have it charging.
It isn't horrible, but try not to let it get too hot as it may shorten the lifespan of the battery.
So this is true for all xperia plays that after some time of gaming the phone will be really warm ?
The phone will get warmer, of course... but 40 degrees is not excessively hot. It feels warm in your hand, but it's not dangerous. A dangerous temperature would be close to 50.
The highest temperature that I had was 44 degrees after a long Nova 2 session.
I am a bit worried by the fact that while browsing the net through wifi the battery heats up to 38 degrees, but it's okay as long as it's less than 50 :> ?
Thanks for the help.
I'd say if it goes above 46 or 47 you just switch it off for a while. Not only because you don't want to overheat it, but because running the phone on higher temperatures reduces battery life (higher temperature means higher resistance to conductivity for metals).
Thanks for the into that it's perfectly normal for the phone to feel warm.
Have you ever reached 50(or that 46,47) degrees on Xperia Play or any other phone ? What app made your battery that hot ?

My former phone, the Galaxy S had HUGE issues with temperature while using 3G. Every time I toggled it on, the phone became awfully hot and the battery drain skyrocketed. I got it on 53 degrees once, since it was in my pocket. I was a bit scared, but the phone resisted it. Still, it wasn't pleasant.
The advantage of the Xperia Play being bulky and plasticky is that it's hard to bring it to extreme temperatures. If it's hard to make it hot, it has a positive impact on battery life as well.

Yea, this happens to me all the time. When using anything that drains my battery it heats it up as well.
All batteries release heat as current passes through them. When the phone is idle, the heat released is low enough your hand doesn't feel it. As the current increases while gaming, so does the heat.
It's nothing to worry about. The batteries are designed to handle heat without being damaged.
Especially since android devices are becoming more popular in places like india, where there's a lot of ambient heat.

I just got my Nexus 7 two days ago and I'm worried about the battery temperatures that I'm getting. When I haven't used it for several hours the temperature is usually 75-85 °F, but after general use (Facebook, Chrome) the temperature increases to over 90°F. Right now it's at 92.8°F after less than an hour of general use. Playing games makes it get even hotter, as you can see in the pictures I attached.
It's also mainly on the bottom left side that gets noticeably warm, I feel like it shouldn't be this warm already. I saw a few people had similar issues, are these temperatures out of the normal range or am I worrying for nothing?

battery temp isnt an idicator of your cpu temp. the n7 has a cpu temp option used by some apps(like trinity kernel toolbox) to show cou temp. btw, its normal for the cpu to go to 60C+ cpu temps on a hot day or during heavy use. anyways, did you realize that the human body averages around 98.6F? so, id even say that your battery is still fairly cool. while charging and using your n7, it would be normal to see battery temps around 110F or slightly higher. oh, and your cpu temps safety is at 100C, itll shutdown automatically if that tempurature is reached.
Might be a silly question, but what is everyone's battery life when playing games? I find that my battery is terrible when playing a decent amount of games, which makes sense, but from what everyone else seems to be pointing too, and hour of a game shouldn't obliterate the battery.
Anyone have any ideas?
for me it drains 3 to 4 times faster, when i am gaming compare to when i am doing more basic task. But that is expected.
Hey when i play nba 2k14 i lose 1% of
Every minute of gameplay
I'm using SetCPU to under clock my cpu when gaming so, it doesn't drain battery as much and doesn't get as hot as usual. And strangely I don't really see performance drop in most game's at 1,5GHz, it's like they using more cpu power than they really need.

The early reports are showing only 3.5-4 hours of SOT. If so, this is shameful on a 3450mah battery. Can anyone say they have seen better than this?
Sent from my Nexus 5X using Tapatalk
Look in the review thread. Some reviews say 6+ hours, some say less. Depends dramatically on cell signal strength, screen brightness, and application cpu use so review numbers are really only useful for comparison to other phones that were tested the exact same way.

In Dave Lee's review, he got 5.5 hours of SoT during a span of 32 hours.
Battery life is extremely subjective, most reviewers will have vastly different usage requirements out of their devices.
There is also countless optimizations that can be done to further improve battery life, most reviewers don't know this and tend to not include it in their reviews and thus end up with lower than expected battery life.
I can kill a smartphone in 2 hours with extremely heavy use, recording 4k and playing games will easily do this while you can take the same device and get 5 hours of use browsing the web and reading forums.
It's all extremely subjective and unfortunately you can't accurately predict the battery life you will get simply because your usage, signal strength and many other factors vary from other users.

You are true for a few reports, however I saw almost all of them and most of them had between 4.5 to 6 hours SOT
Not that it will be necessary but is it possible to easily lower the screen resolution and would it substantially affect battery life?

You mean changing the dpi? I gues it's not hard. There's videos on youtube how to change your phone's dpi through adb without root... But I don't think it will have a difference in batterylife though...
Yes, sorry I did mean DPI. Having to power more pixels doesn't equate to more power?
I don't think changing the DPI has any effect on the number of pixels being used, since the entire screen is still being used. More likely it reduces load on the CPU/GPU by not having to render as high of a resolution.

But this is amoled and only the non-black pixels use power, not every pixel.
First full day on the phone 3:00am-3:57pm not touching a charger, currently at 3h 33m 28s of screen on time using 468mAh and 23% battery remaining (calculated to 4.5 hours SOT for a full 100%). This includes web browsing, facebook, inbox, navigation with screen off, audible book downloads on wifi with screen off, 1 hour of audible playing with screen off, playing 30 min of games, running 2 benchmarks, tweaking settings, 1.5 hours of screen off speaker phone, various xda posts. With the amount of work my phone has done I am perfectly happy with that run time.
Battery usage after first full charge, you can see doze working over night where it lost just 2%
How on earth are you people getting 6 hours sot? Don't get me wrong. That's what we should be getting in such a large battery but I'm trending at 4 hours and have perfect signal

Battery life and Google now
Has anyone turned off Google now to compare battery life? Play services keeps the CPU rolling for a couple hours a day with it on so wondering what the impact would be

Have a read of this thread,i have done tests over the last 4 days .Some using WiFi only,some using mobile data only( in poor signal area ) some using both .Best was 7 hrs + SOT over WiFi only ,6 hrs + over WiFi / mobile data, 4 hrs 48 mins( with 17% battery remaining) on mobile data only and that was mainly no 4G,just 3G and some times just 2G due to poor signal area
