Battery issues

[three-six-oh]

Hey guys I just bought a gnex off of eBay and it came with a extended battery but the battery life is still awful. I'm talking like 20 min losing 10% without 4g and only sending occasional texts. Any help? Is this normal?

Running a cm 10 nightly with GPS off and brightness all the way down. Maybe I just got a bad battery?

Maybe it is a new battery and needs to be fully discharged, and charged a few times for full capacity.

The guy I bought it from has been using it for months.

I got my GNex in May. Typically I have been able to get a day (12+ hours).just recently it dropped to about 6-7 hours. Not sure if.my battery went bad. May try a new battery before I for to a new phone.
