sudden shut down battery problem, factory reset and SW update/repair did NOT help

[Mixta]

Hello everyone, i have a "sudden shut down problem" with my Xperia Z1 C6903 too.

Sudden Shutdown always happens at about 70% for the first time, after been fully charged. I cant turn it on right afterwards but if i wait 1 min. it works. However sooner or later the phone, somewhere between the remaining battery, will repeatedly shut down again. I couldnt find out what triggers it and android battery test show that the battery is ok.

I am not an expert with these devices, but i hope it is a software or calibration problem?

There is a similar threat which points to the solution of using Sony PC Companion Software repair, i tryed it twice and it did NOT help!

edit:

I havent changed the device after PC Companion repair step, thus no other Apps are running and no energy managment has been configured (stamina mode)

edit 2:

hidden battery info * # * # 4 6 3 6 # * # * shows:

...

battery health: good

battery voltage: 3969 mV

battery temperature: 36.6° C

...

is there a way which gives me more details than just "good"? And what does that even mean?

Hi Mixta, welcome to the community! 

That is strange. Are you using original charging accessories or third party charging accessories? I would advise contacting Sony Xperia Customer Care in your region if the software repair didn't help. You can find the contact details for the team in your region by clicking the link in my signature.

How about my edit 2 part?

What is the battery health rating range? And how meaningful and accurate is it?

Is it possible to read out more battery informations?

thank you

Hi, I have exactly the same problem after upgtading my phone to lollipop. I tried repair from PC companion and facfory rest, but no luck.

Do you think it is Because of the battery? Never had this problem before upgrading to lollipop. The other thing I notice is when the phone suddenly shutdown (baterry jump from 50-60% to 0%), I just need to plug in my charger and wait a moment before turning it on, then here is the problem.
1. Sometimes the battery indicator shows 50% or slightly lower than before shutting down.
2. The other times, it will show accordingly that the baterry is out (1% because it's charging)
3. Most of the times, there is a message "android is upgrading...", when turning it on.

Any idea how to solve this problem?

I am having the same problem with my C6903. Whenever the battery level discharges from 100% to about 81% the phone suddenly shuts down showing battery level 0%. Then when I reboot it, it shows battery level of 80% or 50% and then it shuts down very soon after. Sometimes when it is plugged in to charge, it shows 1% charge and if the phone is powered on immediately, it shows a charge level of 70% plus. Each time that I boot the phone it shows "android is updating".  All of this is very frustrating and it makes the phone unusable. This started after the upgrade to Lollipop. My battery test result also shows that the battery is "good".

You could either repair the phone with PCC, if that doesn't work you could either take it to a Sony Xperia Care to get it inspected or replace the battery yourself but this will void the warranty and/or damage the phone if you are not careful.

I already send it to sony service center coz i I was afraid to lose my chance with warranty.
