I dropped my phone a few days ago and now my bottom speaker is muffled and static. My top speaker is working great though.

Try closing all open apps, by pressing the recent apps button on the bottom of the screen. Close the apps by swiping them to the right. If closing all the apps doesn't help with your battery life issue, it may be a problem with the battery itself or the phone may need to be recalibrated. Check out HTC One (M8) Troubleshooting for more information pertaining to your phone.
