I've been using Mate30Pro for 2 months now (with GMS) and so far very pleased with the smoothness, speed and also battery (average 8.5hr SOT). Also the 3D face unlock is the prime reason I still stick with this phone, can just double tap and voila unlocked in the middle of night.

There are few drawbacks though

- Battery from 20% onwards drop crazily fast and the phone will shutdown at 2%, it's the same across all Huawei lineup I guess
- Heavy
- Mono bottom firing speaker (sigh)

Actually i went thru the hassle of setting the power details -> app launch of each app upon installation, to allow certain apps (whatsapp, grab, foodpanda etc) that i wish to run in background, the rest of them i just turn off when not running (eg. instagram, fb, games, waze etc).

Hope that helps.

Recently I take more photos than before and started to notice one annoyance with m30p, which is the shutter lag...when pressing the camera button fast enough you will notice it usually does not take subsequent photo immediately, this is annoying considering I wanna capture THE MOMENT that comes and goes.
