How do i know how much long is my device going to be on

[TuhinS]

you can see it in the device maintainence battery tab

[Abhy]

Go to settings
than Device And Maintenance
select battery tab
and there u have it

[kerneldeveloper]

how long your battery will power up the device is based on many factors but a standard result can be seen from device maintenance option

but that is just a standard result .. it actually based on what apps you have , what apps are running or what consumes how much power so you can not predict the actual time or how long it going to be
