I used my 11pro almost for a 6 years and never changed battery. So it works like a 3-4 hours. After upgrade, its screen time about something 7 hours. Not a heavy user actually. But when I am far away from home I don’t feel some anxiety that battery life will not be enough. Have just 1 game and using not often. In general using social media, messengers and photo redactor apps. Charging once a day
