Random reboots when 60% or less battery, phone turns off when fully charged

[BrankoDz]

Hello!

I need help! I have been using my new Sony Xperia Z3C for 4 days now. It came with Lollipop update.

Everything was working great when I opened it, but not for long. It started to reboot more and more frequently and anything could set it of, home button, typing a screen lock PIN, using any app or just while in stand by!! Crazy.

After that frustration I hoped it was a software issue because that I can solve. I started with PC Companion update and after that same thing. Ok, I thought the version is the problem. I went with older versions of Lollipop firmware. Again, same thing, after some time of usage phone starts to reboot uncontrolably. Fine, fine, I thought okay Lollipop is the problem, I need to go with Kit Kat. I did that and after successfull startup and app instalation, account logging and everything, guess what. REBOOT!

Then I noticed the weirdest thing, When I am charging the phone, it works like a charm and when it is almost full. When it drained passed 60% battery level it started to reboot again and this happens every time. When I charge it again it works just fine until 60% again. Other weird thing is that the phone TURNS OFF completely when it is at 100% charge.

Can I fix this at home?

Cheers,

Branko

That seems to be a hardware issue, contact Sony Xperia support

You can also remove the sim card and use the phone without for a few hours. If you don't experience the same problem it could be a sim card issue, if not it's a hardware issue

Hi Phy,

yes I allready did the SIM card and SD card test and removed both of them but it's the same issue. Sometimes it works for hours without a problem and then it starts to reboot every few minutes. It really has no rules.

I guess considering all the similar topics I read and your suggestions it is definitly a hardware issue.

Thankfully I will get a replacement on Monday.

I will update what kind of issue it was if I get that information.

Cheers!
