I have a sony xperia xa1 ultra and I've had it for almost a year now brand new and recently I left my phone on the counter at 60% and went to bed. I woke up the next day and it was 0 I tried charging it and it took hours before I could get 1% when it got to 100% it took 20 mins to die the phone no longer holds charge. I thought it was a charger problem so I changer it and same thing happened then I changed the battery and the problem persist
