My cell phone battery died...?

Question

My cell phone battery used to work great. A single charge would last about 3 days because I used it so seldom. But, for 3 months it sat unused in my room because I was using another phone with work.

Now, I'm back to my old phone, and a full charge only goes half a day, and I'm not even using it that often.

Did letting it sit for 3 months cause it to go bad, or did something else happen?

Answer 1

Yeah it went bad.Before letting a rechargeable battery sit for a long period of time you should discharge it completely.

Answer 2

just get a new one. u should buy a new battery once a year anyway

Answer 3

Probably it went bad and that it might have also been fixed.
