Z5 Premium: On a full charge - What is your Predicted battery duration (in and out of Stamina)

[GreyFoxIndy]

I think I have a severely defective Z5 Premium. On a full charge WITH STAMINA mode on (plus all options checked) I am getting 18 Hours predicted.

Friends of mine have a z5 premium, out of stamina mode with much more duration predicted.

Please post your results.

I'm a heavy user so I have 17hrs, keep in mind that I take a lot of pictures, play and stream videos and music, play games, have multiple accounts synced and I upload pictures, etc. so 

17 hours estimated battery time 

1 day 12 hours in Stanby mode 

5 days 17 hours in STAMINA mode

14 days 7 hours Ultra STAMINA mode

It just depends kn your usage. If you leave your phone for like 2 days,  the estimate duration will increase but if you will start playing a game for 15 mins it will decrease.

Mine says 10 days and change on Standby.

You can reset that time easily but there is no point. That is your usage pattern and it will always measure according to your recent usage pattern.

As said, it's based on previous xx amount of time usage.
If you remove from charge and leave it on standby for half an hour it will show 17hrs+
If you remove and boot up a game or something it will show under 10.
Always has been the case too tbh on all the Xperia that has it
