Xperia Z power off on 50% of battery

I have Xperia Z on 4.4.4 version. Everything works perfect, but phone power off when battery reaches 50 - 48%. I tried reinstalling ROM but no positive results. No matter which app I use, it just powers off. After that I can't power on until I plug it on the charger.

Phone is new and I doubt it's battery issue. Any suggestions what to do?

 

Thank you in advance!

Contact your local Xperia Care as this could be a hardware issue

Re: Xperia Z power off on 50% of battery

Thanks for your reply but I think I found the fault.

 

I played game before and phone was heated. When I started camera after, phone powered off and lost setting for camera storage and even WiFi passwords. I guess that overheated battery after playing HD game can't give enough power to start camera, can't tell for sure.

This error also gave me problem on this thread http://talk.sonymobile.com/t5/Xperia-Z-ZL-ZR/Xperia-Z-Camera-Shutting-Down-Restarting/m-p/960041#M56..., but I fixed it. No high resolution games for me anymore.

That's odd, I don't think its a phone issue but that specific game.

It happens again.

I've just run Sony battery test application and it's says that battery capacity is reduced. All other tests are ok.

Could this be reason? I don't mind buying new battery but what if this happen again? I don't know what to do. Now it shuts down on 75 - 80%.

 

But there is strange thing with camera. It happens mostly when I start camera and look how my DCIM folder on SD Card looks like

I tried that few weeks a go, but gives me same result. After that I repaired my ROM and it's the same.

 

I think this could be battery fault, since Sony battery app test gives me "reduced capacity" result. But I can't be sure.

 

I wish someone can confirm this: if battery gets reduced capacity, voltage gets reduced too? Because it works good until 75%.

Re: Xperia Z power off on 50% of battery

I've just read on this forum same problem with other Xperia Z series. Comon problem. It won't start unless connected on charger. Can anybody say what is exact problem? Repairing with PC companion doesn't solve this. I can't get my phone to Sony service, it doesn't exist in my country. I just want to know what is problem. If it's baterry, I can replace it in other phone service. Please, someone!

You could buy a new battery and replace it yourself, that might solve the problem

@Dragoslav 

 

I've taken apart an Xperia Z before, not hard, just have the correct tools and read and watch the disassemble guides

make sure to buy the double sided tape that goes around the perimeter on the back panel.
