Why is my battery draining so fast (Huawei P20 Pro)?

[Android Central Question]

Ok, I've been using this phone for more than a week. I think it's great, but the battery usage is driving me crazy.
Yesterday my screen on time from 100 to 20, with very light use, was 2 hours and 20 minutes, and while using it the battery drops like 1-2% every 3-4 minutes, which is very frustrating.
I tried a hard reset (+ wipe cache) as well as a soft reset, with no results.
Yesterday I installed BetterBatteryStats to look for anything suspicious. At the moment, the only strange kernel wakelock is ts_wake_lock, which also appears as an Active Process. Do you know what it is and how to fix it?
Moreover, the WiFi icon in the notification bar is always showing the double lit arrows, as the phone is constantly receiving and sending...

Any ideas? Thanks

My guess and usually the case you probably have a rogue app that's draining your battery. I have my Huawei for almost 3 weeks now no issues I get almost full 2 days. Have you tried factory reset? I would go through each app that you installed aside from the ones that comes standard with the phone and see which one is known to drain your battery go from there.

I think you must have a defective phone at the end of the day I usually have min 40% sometimes 50%and I get heavy use

Dunno if mine is normal but it stays at 100 percent for ages, with 30 mins of screen time and using sonos app it's still at 100 lol.
