Hi @Jonas, Thank you for offering some solutions. The software repair did not solve the issue and so the battery life still falls very short of its advertised ability. Again appreciate the local support team link - although I will not be using it because i think after a while I will face the same issues again. Basically my 'trust' in Sony is gone (coupled with owning a Z3+ that also had battery issues!). All the best, Tom (aka dfadfgfdgh)

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.
