To repeat what I posed two days ago.
I speak from personal experience.
Don't leave it charging 24/7
I ruined one that way.
I used it as a hotspot all summer at the cottage.
As it was explained to me. The phone will stop charging at 100% but it always sips away using background app like wifi, blue tooth etc. The battery drops to 99% so it charges up again.
If it does that for hours on end it will heat up and deteriorate. Mine swelled up so much it popped off the back cover.
You got lied to by whoever told you that in order to deflect responsibility for a defective battery/phone charging system.
If I remember correctly there WAS a rash of defective Lithium batteries a few yrs ago, good chance that was your problem.
