Can confirm, it insanely drains the battery and gets hot. I know this is a really power consuming thing but coming from the 11 Pro I wouldn’t expect this. Next to this, it gets hot - really hot and this being said at 10°C (50°F) outdoor temperature. I’m afraid to see this next month on vacation at 40°C (104°F).
Overall I’m not that happy with the 15 Pro especially knowing that I bought it as my daily driver for the next 5 years…
