Why does my Samsung Galaxy Discover lose all battery power even when turned off?
Why does the Discover phone lose all battery power when turned off over night? It had 99% and went down to 4% when powered right off!?
This is the second phone (first was replaced with this one) to do this. The phone is shut right off and it lost all power over night. What's with that?
It could be a battery issue. It shouldn't drain while turned off. You should notify Samsung immediately so you can get a replacement or just get a different model if they let you to.
