Hi Fellas,
I had this Sony xperia z3 compact tablet that i bought from swappa earlier this year. It came working and in perfect cosmetic condition but after about 2 months of usage the battery started draining out very easily to the point that the tablet can be 65% charged and the next moment it's shutting down. Lately it got worse as it shuts down even when the battery is 85% charged. I've contacted the seller and sony nd nothing helpful came out from them. I need help on how to get this battery issue fixed so that i can enjoy my tablet like the early days. It's running android 6.0. Thanks

Having a similar problem with my xperia z3.

dont understand what's happening with my phone. Have old Xperia Z3 D6603 (running android 6.0 marshmallow).

Had problems with battery since it was not lasting even 5 minutes so bought a new battery from ebay and installed it yesterday.

So first time I put it to my phone it showed that it had 70% of charge. I've read in battery description that I have to discharge the battery and recharge 3 times.

First time I wanted to discharge from 70% to 1% and with a battery discharge app + youtube 1080p videos + wifi signal it took only around 1 hour and phone was at 1%. From 1% till complete discharge it took me extra hour and then phone died.

I plugged it to charge and after 15 minutes it showed that battery now is at 100% (which is insane, it should take 2-3hrs to charge it up to 100%). So I charget it for 2-3 hrs ignoring that it said 100% already.

I discharget it from 100% to 1% in 1 hour and now again phone is stuck at 1% and it took me 2 more hours to discharge phone until battery died completely.

I don't believe that this behaviour will fix itself. How can I fix this problem so that battery percentage would be distributed evenly? Now it drops from 100% to 1% in 1hr and then from 1% to 0% in 2 hrs.
