I have had my Xperia Z4 for nearly four years now. Is it fair to assume that I should expect the battery to be very poor by now? I ask because when my tablet is in idle mode it can last for over one day easy. However if i use the internet or YouTube I get about 3 hours of life. This is with the screen set to its darkest setting – I use it before bed mainly. I have used the battery usage app to check and the graph takes a massive nosedive whenever I use the internet or YouTube. Also, as suggested in another thread, I downloaded ‘GSam battery monitor’ to check no apps were running. (I don’t play games on my tablet either). Lastly and this probably related to the battery, when I do use the internet or YouTube often when the tablet gets to 35% battery the tablet just shuts off. When i try to restart I get the battery symbol. Does this sound like I need to purchase a new tablet? Thanks Tom P.s. apologies for the random name displaying!?! Steps taken so far; 1) I have done a factory reset. 2) Made sure everthing is up to date. 3) Activated stamina mode 4) Kept screen at lowest brighness Seems like the tablet has lived its life.. I would suggest people purchase an IPad or a Samsung.
