Hi just wondering if anyone could shed some light on what the others is in my battery usage.

Shows the same on both my P20 & Pro but haven't clue myself. Phones are functioning just fine so not overly concerned personally.

I have some problems with my one week old P20 Pro with all the last
updates, the battery life remaining appears to be completely random or depends on the phone mood, right now I have 87% left and that gives.me a total of 12h42min left, other times I have like 60% and it says that I have up to 20h left. So is this some software problem? I don't see the phone dryning more power than whem it have more batery life time.

I would never put full confidence in those Estimates, ever.

The estimates literally go by how you have been using your phone, but they don't consider how you are currently using it, e.g. If your phone was sitting idle you pick it up and it says 20h left at 60%, that's 20h of it being in idle usage, however if you start gaming and playing YouTube for about an hour that Stat will soon change to 10h left, but then let's say you stop gaming and YouTube that doesn't mean you have 10h left, it means if you had kept going with the heavy usage you'd have 10h left.

It's like trying to use the range estimation in a car.
