How come my battery percentage goes from 80% to 20% in a matter of minutes?

All of a sudden my battery life stinks.  I think i got a back update or app download.   I will be using my phone as normal and all of a sudden my battery will go from fully charged to dead in a matter of 5 minutes.  I'll plug it in or reset it and it will instantly come back to 50-60%... Something serious is going on.   Thoughts?

Could be battery nearing end of life or that the battery meter needs to be re-calibrated. Try the latter before replacing the battery.

Getting the most out of your battery life is definitely important so I completely understand how you feel SMHAMILL. How long has this been going on? Has there been any damage to the phone? Do you have the most current software version on the phone?
