need backup phone first before update 13?

i read somewhere not slow charging, some kind of after 80%, will stop charging
some gives example like you sleep at 10PM, wake up at 7AM, if you charge your phone before sleep, once reach 80%, iPhone will stop charging, it learns your charging so will about to know you wake at 7AM, so will continue charge to 100% before you wake

maybe some algorithm build into it some have different experience base on person charging time.

it need to learn how you charge first

Guys, have you had a problem where you try to reset your iphone, after putting in your passcode, it asks for another passcode? My passcode is 6 digits, after inputting the first passcode, the iphone asks for another passcode which is weirdly 4 digits. I've been trying many passcodes already which is turning out wrong. IIRC i've never set a 4 digit passcode.

If you are running iOS 13.2 then you should update, it fixes the ram management issue

Which iPhone?

Can skip, if there are no major issues with your current version

It doesn't work instantly after you turn on that function, it needs time to learn and adapt to your charging time...... and I don't think it works for me because of timer

Same, on iOS 13 since beta1 and it doesn’t seem to work for me( maybe because I charge during the day?), using an iPhone 7 too.... to me, I’ll just leave it on and pretend that it doesn’t exist

Not sure if this is related, but some times while charging somehow the phone screen turns on and shows the battery logo as if I just plug in the phone
