I've now had this battery for 9 months. At first, my battery performed nicely. I had similar results to
Gigi's tests. The video would play for almost 4.5 hours on this battery. Now this battery, when playing a movie, only lasts just less than 3 hours. Ouch. That's how much an 1100mAh battery should last.
I tried looking up the warranty and what it includes. I bought it from Cases.com where it comes with a 1 year warranty. My packaging is vague on describing the warranty. Does it cover degredation after a certain percentage? Does not cover degredation? Does it only cover manufacturer's defect? I couldn't find details anywhere.
I expected some degredation, but not this much this fast. This is a 33% loss of power. Anyone have problems?
