xperia z2 is easily to get hot

[kevinchiu2k]

I just brought z2 a week ago. but the unit is very easy to get hot. it's seems to me that z2 has hot dispation issues. it gets hot even i didn't use any camera function, such as play audio , watch viedo. if compared with my previous phone (other brand) , i almost didn't experience such a hot issue. i am wondering if it's a bug for z2 or wrong design? who can advise what's the cause of the issue?

Yes mine seems to do this too! Does anyone know of a fix?

mine causes the camera to stop working when it overheats. Come on Sony, sort it out!

I found that if I disabled "STAMiNA" power saving function, it works better now. I am wondering if the heat issue comes from the feature.

it's no denying that when you use camara function, it's easy to get hot. sometimes "warning" message pops up saying "the function" is stopped due to the unit's over heat. I experence 2 times after I brought it within 1 week. I don't know why the problem occureed as I never experience the issue on other brand product. is it normal?

It's normal that the phone gets a bit warm when you use it. When in use the components like CPU, battery, and other parts gives off heat. The phone has builtin protection against overheating and in case it gets too hot you will get a message about this on the screen and the phone may then turn off features or itself to prevent overheating.

STAMINA is a powersaving function that enables 15 minutes after you have turned off the display. It prevents apps from waking the phone and using data. While you're using the phone it will not affect how warm it gets.

Thanks your reply, I ,of course, know that the system has protection meachaism, but if users get hot in very short time. for my case , I started shotting (4k video) or using camera function (the later last longer to get hot), and the machine gets very hot within 1 minute and the function disabled forcefully by system. If users got a perfect features, and they can only use less than 1 minnuts, which means users cannot use the feature comfortablely.It's really a big problem. If you check out the forum some people have reported the same issue. I'm not the one to experience heat issue. To be frank, I am frustrated about this new phone. How come Sony doesn't notice heat issue before delivering the product?

So is mine. Battery lifespan was good at 19 hrs for first 2 weeks. Then, it went downhill to just 11 hrs even with mostly on standby. Also last 2 days , battery getting warmer. Notice under power management, it showed android system taking up 50% even during phone idling mode

Same here. The z2 gets very warm during camera and game usage. I don't see how a software update can fix this..

I think it's the battery because I have seen a teardown from Sony smartphones and where the battery is the Sony Xperia z,z1,z2 overheats.Maybe you heard that some notebooks from Sony overheats or other things.It's the battery.Sony in future please produce better batteries or use some from other brands.But just good brands.
