Battery

[lungisan]

I just bought Samsung A34 the battery drain very fast it doesn't even last a day

since the device is new it need to learn ur usage patterns, after this then the battery won't drain as fast

Probably you have plenty of spps running in the back ground.

Usually its normal. Your usage is higher when the phone is new. 5000mah is not enough to last the whole day under heavy usage

5G and 120hz refresh rate could be the cause, maybe also try dark mode
