Battery drain with screen left on

I just received a newly-purchased Ace Pro 2 a week ago.

I did a battery life test with the following parameters (tried my best to adhere to standardised testing parameters)

- WiFi and Bluetooth off

- Active HDR on

- auto screen-off in 30 seconds

- Ambient temperature (air conditioning) at 25°C, low fan speed blowing at the device to simulate outdoor natural wind

- 1080p, 30fps

The battery drained from 100% to 20% in 1h45min which I think is quite decent.

However, I quickly noticed that while just swiping with the screen on to adjust the settings, the battery drained 2% within just 2 minutes.

So I did another test, leaving the screen on for 15 minutes with the same settings as above, without filming. And the battery decreased from 55% to 45% within 15 minutes.

Just want to see if this battery drain while the screen is on is normal. Thanks!
