Help Battery and processor heat up when playing games

[femmycats]

Hi guys, it's about my new Samsung Galaxy Note 2 again. (First smartphone and new to everything.)

I notice when I start playing games (didn't really play much however), the back cover of my phone (near the camera, and the bottom part also) heats up. Same with the touchscreen. It's not really "hot"; it's warm.

Asked many friends of mine and they said this is normal. Smartphones heat up when we play games and surf net. I used AVG's performance function to check the battery temperature and it showed 35

It's perfectly normal, you don't have anything to worry about. 35

That's normal. Any device using electricity heats up. Heck laptops heat up to 90C, desktops even more.

Your sensor shows the temperature of the phone's battery. Because it's the phone's most sensitive component.

The Li-Ion battery's temperature operating range is:
for discharging -20C (-4F) to +60C (+140F).
for charging 0C (+32F) to +45C (+113F).

So don't worry about 35C

What does operating range indicate? Why are people more concerned about battery temperature rather than processor temperature?

 

[Hadron]

Because the battery is more vulnerable to heat damage than the processor.

Also, when the processor gets too hot, most phones are coded to turn themselves off. I'm not certain there are similar safeguards in place for batteries.

Thanks

What does operating range indicate?

Most (electronic) components have an allowed temperature range for operating (being active, switched on) and an allowed storage temperature range for being stored (being not active, switched off).
A processor's allowed storage temperature is higher on the high end and lower on the low end than its allowed operating temperatures.
A battery's storage temperature range is the same as its discharging operating temperature range because a battery is never really off

Why are people more concerned about battery temperature rather than processor temperature?

A processor's highest allowed operating temperature is far higher than the battery's ... and the processor can shut off itself (restart the phone) when its temperature limit is reached.

I hope my clumsy description is understandable

Thanks! Very useful information indeed!
Now I use Clean Master to release RAM every now and then. But most processes would restart even if I'm not using the apps. Would it result in more effort for the phone to relaunch the apps again? Shall I just let them occupy the RAM since I still have about 1GB of free RAM? Sorry that my questions are not very organized..

You can leave the RAM alone. I only clear my RAM if it reaches less than 500MB free space. In which case I know because things start getting a little sluggish. Otherwise I leave it alone. I also let the built in task manager handle that. I only use Clean Master to clear the cache and junk files.

My opinion too

I'm now playing certain apps and I would run them many times a day. Sometimes I just play for 10 minutes and quit, then maybe half an hour later I would go for it again. Wondering if this would eat up my RAM or bring any "side effect" to my Note 2?

 

[El Presidente]

Nope, what you're doing is fine.

Just let the OS handle RAM/task management. As NeoGrandizer says, if things start to get a little sluggish, then look at clearing RAM, but for the most part, you can leave it alone.

I'd love to have 500GB RAM.

Anyway, my phone doesn't really slow down until I go below 30MB RAM.

LOL. Oops, yeah, supposed to be MB. Thanks for the catch. Fixing my post.
