Xperia Z1 battery comes down to 70-75% very rapidly and gets shutdown.

PBhowmik — Wed, 25 Feb 2015 16:48:24 GMT

Xperia Z1 - Even if the battery is charged to 100 % it comes down to 70-75% very rapidly while using camera and video and at 70-75% battery remaining it suddenly drops to 3-4% and gets shutdown. And normally to even if it is in standby mode even after charging to 100% the charge gets reduced very fast. Please help. I have battery doctor installed and it is showing that health of battery is good although the charge doesn't remain at all.

I would suggest you to remove any kind of battery savers,task killers etc. See how it is without. It should improve.

Hi PBhowmik,

Welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.

If the battery is dropping down from 75% to 4% instantly, than this is likely related to software. I suggest performing a software repair on the device to resolve this issue.

3. Install and open PC Companion then select Support Zone.

I too have the same problem. I already have 2 factory reset with PC Companion. The problem persists. Just use some app or discharge from the internet immediately warms processor and battery. Should I change the battery?
I reported the problem to Sony Italy opening a ticket but I have never responded!
Sorry for my english

I solved it by changing the battery. The phone seems reborn. I hope that the problem does not recur.
