It's draining a bit too fast for my liking?

Do you watch 4k60hdr or something ?  I wonder.

-70% for 5hr30min of YouTube possibly high resolution/FPS doesn't sound that bad.

Was that high brightness on the screen?

Don't get me wrong, but when battery tests are conducted, they put one video on and it's just playing. Not clicking one 4K60 HDR , buffering next 2 min with 200MB downloaded in 10seconds. Then clicking other spot instantly downloading. Another 100MB immediately  and checking new videos every 10sec.

Battery tests on reviews just click on a 1080p30 video or something at like 50% brightness and just let it sit. No UI clicks , no seeking in the video, no changing videos every 2minutes. Device is just chilling for a few hours on few long ass easy to play videos. 

UI interaction keeps the CPU at high frequency for responsiveness. Seeking and changing videos hits CPU pretty hard, again for responsiveness. High resolution screen hits GPU hard regardless. High brightness setting too... And more and more.

Try clicking a single long documentary at 1080p30 one day, let it play at 50% brightness then come back to it 1 hr later and see how much it drained.

Nope absolutely not, just normal 1080p content no HDR no 4K or any other things.

Sometimes applications are borked in some way.

Force close the app , reboot the tablet and perhaps even try an alternative way to watch YouTube. Like on the browser, with adblock no less. 

New devices sometimes aren't quite calibrated yet with power usage for a week. Background tasks , updates, etc.

That's very high. Unless your brightness and audio volume is also very high. Where you watching a livestream or something?

No, nothing like that.

That is very high then. If it is not software, it could be hardware. If your tablet is heating up because of the ambient temperature or if sunlight is directed at your tablet.

Heated battery consumes way more power.

Please come back to this post after a week to share if the problem persists or is fixed.

Others like me are eyeing out this tablet possibly in the future.

I'm really more concerned about desktop mode, working it as a laptop.

Anyway, afaik Snapdragon still doesn't support Linux terminal, and thus no GPU accelerated Linux apps, etc which is a bummer.
