har prövat att köra telefonen i normal mode och safe mode de två senaste nätterna.
Det som stack ut mest var battery usage för displayen:
Normal mode: 24%
safe mode: 2%
i båda fallen så har batteriet varit fulladdat och jag har givetvis inte använt telefonen alls under natten. 
Jag har varit i kontakt en hel del med Sonys support (även visat dem siffrorna i det här inlägget) och deras svar var:
"If you look at your screenshot called "graph_normal.png" you can see that the phone has been awake alot (the blue dots shows that it's awake). If you were not using the phone during this time it means that you have an installed app that it waking the phone up from sleep. The app itself might not use alot of battery (which is why it doesn't show up in "usage_normal.png") but it causes the display to drain the battery. If you check the permissions of the apps you have installed you can see which ones that are able to prevent sleep and then you could try to remove these one at the time. In most cases there's not a big difference between normal mode and safe mode but safe mode is a good way to see if a 3:rd party app is causing the problem."
vet inte vad jag ska säga om det ... Men när jag återigen påpekade att det var märkligt att displayen drog 24% under en natt utan att användas så sa de:
"There might perhaps be a problem with how the phone displays the power usage. When looking at your screenshots again we see that the display has not been active that much. There is however a clear difference in awake so one or several apps you have installed must be keeping the phone from sleeping. To test this for sure, please uninstall all 3:rd party apps and test power usage in normal mode again and see if you get about the same result as in safe mode,"
Bara att börja testa då. tagit bort hälften av mina egeninstallerade appar som kräver permission att kunna hålla telefonen awake.
