Overheating?!

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.

[Q] Battery Temperature Questions

My Vibrant has always run warm, and I never paid much attention until I started running an over-clocked kernel. It got me to thinking:
1. I hear there is a temperature warning notification that pops up when it gets too hot. Anyone know what the threshold is for this?
2. At what temperature is damage likely (somewhere above the notification, I would assume)?
3. Are there any hardware based failsafes, such as something to prevent the battery from attempting to charge when its too hot?
I tend to run around 90 under light usage and up to 110 for heavy usage (doesn't seem too bad considering the temps can get up to 120 in the summer around here). Hotter when the battery is charging. Just caught it at 127 while browsing the web and charging, which is higher than I'm comfortable with, but I still didn't get a temperature warning notification.

Mine can get up to 120 when surfing and charging. I usually quit what I'm doing at that point, that much heat in that small an area makes me nervous.
I've had a couple of apps that get the phone quite warm, then lock up or force a soft boot. Unfortunately I'm not able to see the temp at that point. Judging by feel it is below the 120 degree mark tho.

I have been in ovens calibrating airflow speeds (130F at 75mph) and haven't had battery problems.

phone temperature

I was wondering if any one else's Atrix gets pretty warm/hot from use. I was expecting the dual core to generate heat but it does concern me a little. The battery app I am using displays the phone temp and when its idle it is about low to mid 30's. I noticed today while using the gps and playing music at the same time the phone started to get pretty hot. when I looked at the temp it was 45. It didn't get any hotter then that and I tried moving the phone out of direct sunlight to see if it would drop the temps a little but it still stayed pegged at 45. Playing one of the dual core supported games the phone would hover around 40-42 deg. Are these normal operating temps for the phone?

I don't have an atrix.. yet. but could it be due to the 1960mAh battery? that would in theory heat the phone up quite a bit..

I haven't checked the numbers, but what you describe matches my subjective experience. Most of the time the phone stays cool, but when it can get warm during an extended Samurai II session or when charging from less than 50% battery.

I think in one of the other multiple battery threads someone explained that the heat is coming from where the processors are located, the bottom portion of the screen.
My Atrix does get noticeably hot when streaming video or playing games...

The dual 1GHz cpu, gpu, and 1GB DDR2 ram packages are stacked on top of each other, just above where the speaker grill is. I'd expect that to get quite warm.

45C is not that bad. I hear about people running their phones to 50 - 55C. The only issue with prolonged use at that temp would be decreased battery performance. Even then it would need to be running at that temp pretty constantly to have any noticeable effect unless you plan on keeping the phone for more than a year (which would be impossible for someone like me anyways, I like shiny new things)

[Q] Battery heat ?

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.

Galaxy s4 cpu temp

OK usually my CPU hardly ever exceeds 60c. Only when charging and watching YouTube at 60fps. Usually when browsing it remains 45-55c and no more. But it decided to stay at 59-64c over the past 20 mins and peaked at 68c. I went into dev settings and enabled CPU monitor and found twitch was causing the CPU to overheat (more than the s4 does already). I uninstalled it and. As I type this I'm around 44-47c. Was that really high temperature, and the relatively high normal operating temperature damaging to the phone. Or just uncomfortable to hold?

The top part of my screen has a darker tone than the bottom part. It's hardly visible in most cases, but there are time when you can clearly see it.
Don't know about the motherboard and such, but I'm pretty sure this screen tinting is a result of the heat, since it's the top part that always gets hot.
But I'm also a heavy user - I use the phone from morning to evening and the screen is pretty much on all that time during that period.
To exemplify: I woke up like 6 hours ago and the screen was off maybe a total of 30 minutes in those 6 hours.
So maybe the heavy usage + heat is what caused this degradation.
Anyway, this is bound to happen at some point anyway, regardless of usage and heat - that's the nature of AMOLED - though the process may be accelerated by using high brightness and the aforementioned heat.

My temp seems to skyrocket just after boot and after clearing ram once about 1 min after it will drop 10 degrees c
