A reboot will often fix this issue... "Have you tried turning it off and on again?" Is a tech support cliché for a reason.
And it can't be 3 months old... They stopped selling the 3T getting on for a year ago... If you bought it new and sealed, the phone would have had to be sitting on a shelf for months.
There is no an app going nuts
I checked..
But the performance of the battery changed suddenly
I rebooted it several times but no gain.
It Was 6 hrs SOT
NOW 4 hrs maximum
What may be the reason?
