Weird battery issue
I'm having some weird battery behavior. I plug it in to charge every night. Many times, when I unplug it in the morning, the battery will almost immediately drop from 100% to somewhere around 25%. After that initial drop, the remaining depletion rate seems about normal. It doesn't happen every time, but it is happening with more frequency. This was happening before I rooted it and put Hyperdrive on it.
Is my battery dying, or could something else be going on?
