Did I screw up my battery? Or phone? (hopefully not the later)

I went on a 1000 mile ride this past weekend and I used a battery pack that I've test before, so I can use GPS tracker while riding and not use up the battery. Friday and Saturday worked great, riding for some 8 hours and when done, the battery was still at 100%.

Sunday however was hot and I think the charging circut cut out as the phone drained and there was plenty of juice left in the pack. When I got home NOTHING would let the phone boot up (laptop, another wall charger, battery pack) except the charger the phone came with. So I charged it until 100%.

When I went to bed, I put it on the other charger that I've been using at night since having the phone and even though the battery icon was cycling as if it was charging, it was not.

Do I just need to replace the battery? Leave it on the stock charger for 8 hours to "reset" it? Is it the phone?

 

Update:
The battery charged and will charge with the different media. As an excuse, I went and bought another battery, really hoping that mine was F'd up and I'd get some renewed life, but alas no. Both suck equally.

I can swear that my battery life is going downhill, but I could just be hyper sensitive to it. Still no where near the way it was when I installed 1.0.
