Very Strange Battery Behavior

O no, not another battery question. My apologies.

I have a 4S and noticed recently that after about 5 hrs of light use, the battery is completely depleted. Pressing Home button does nothing. Never even get the "Less than 10% left" warning before it shuts off. Ten minutes on the charger and the screen comes back and battery shows ~ 55% charged.
Obviously none of this makes any sense.
Has anyone seen anything like this before?

Given that the 4s is now 5 years old, I would recommend taking it to Apple and having the battery replaced.

It makes great sense, sounds like your battery needs to be replaced.

Funny you mention that. I replaced the battery a couple of months ago. Maybe a defective battery?
 
Dude its means that hold the home button and power button until you see the black screen and then the apple logo
 
Could be the replacement battery was also second hand and had been used before.

There are apps out there which show how many cycles your battery's been through, worth checking new ones when first installed to make sure you've not been sold a dud.
 
From what I know only app which can show you battery cycles is CoconutBattery only for Mac. With iOS 10 introduction these info is no longer available on phone - no app can get this info.

It could also mean the battery you used was not an OEM Apple battery and that could also be a problem.

That's what I was thinking.

Hopefully, with a 4S, the OP isn't running iOS 10.
