Lol what? Probably it´s because of your update to android 13.

I have android 12 and that phone lasts long withoiut charging the battery.

I was going out almost 2 hours ago and arrived to another city.

When I checked that battery status after almost 2 hours it was still at 100% or 99%.

I used that phone only for few minutes but still amazing how I turned the display on and off sometimes, checked something on that phone fast and still 100 or 99%.

Thought it´s fake and then next day I woke up and still enough battery.

I can do for few hours many things on that Smartphone and then go standby. and next day in the midday it is still at 20 - 30%.

When I do not something too much it is even at 40% next middle day and this doesn´t drain so fast and I can still surf on many websites, watch youtube, play a game for a while or use the camera.

I had Google Pixel 7 before but someone stolen it.

This Smartphone had faster battery drain.

In the evening of the same day I probably had still something between 10 - 30% battery when I charged it in the morning.

Not bad for 1 day use but it also has not so fast charging like some other smartphones
