Reduced battery life after update to oreo

Hi! I bought my xz premium a week ago and now I have decided to pass to oreo. Unfortunatly I discovered that the supposed battery life went from a predicted 16 hours or more to a mere 12 hours, and that's after a full charging battery. Did someone else find this problem or I am the only one?

Re: Reduced battery life after update to oreo

If you go to your settings - > battery then click on the three dots and then select consuming apps.

See which app is using the most battery.  As you can see I'm getting over 24hrs from my Xperia xz premium with Android 8.

I can't really complain about battery life on Oreo. I'm getting up to 8 hours of screen on time.

Good suggestion from LoveMonkeyGod!

If you cannot identify the issue...probably a third party app not playing well under Oreo...then try a factory repair using Xperia Companion on your PC.

 

Yes, it is a pain and will make you set everything up again from scratch, but it may just fix your issues. Do not do a factory reset from the phone as it is not the same as a repair from your PC. The repair installs all new software.

Yeah I tried that but it's definitely something that's wrong with Oreo.

 

I did software repair then I DID NOT INSTALL ANY ADDITIONAL APPS and left the phone for 8h without touching it. Same drain on idle as with apps (4-5%) so it's definitely Oreo fault as on Nougat it was more like 1-2%.

 

It's not a rouge app, it's Oreo as on Nougat the battery was much better for both idle and active use....
