Hi all, I have a z1 which is around 4 month old. After the kitkat update I notice my z1 is taking an absolute age to charge.
I went to bed the other day with 16% remaining and so I plugged it in while I slept. I woke up 3hrs later to go to the toilet and when I came back I checked my phone and it said 53% battery. No way does it take 3hr to half charge the battery. I left it and went back to sleep and around 4hrs later when I woke up it had fully charged.
I also noticed that if I use the phone while charging, the percentage goes down whilst in use, never noticed that before either. And the battery drains faster than before.
