I've got 2 of these batteries with different part numbers but I think they are the same. One says just HTC and the other says HTC Innovation. Same exact batteries though, I think they are just different because they were OEM batteries for 2 different models.
Well, yesterday I got 38 hours on the battery. Couple of work calls/exchange emails. 1 hour of robo defense, txts, and about an hour on facebook and the net.
I just charge one on an external standalone charger while the other battery is in use. Then I just alternate switching em. Works great for me.
I'm pretty happy since it lasting about the same with my storm 2. However, I would still like a fix for the charging issue while the phone is on. I'm afraid one day my phone will get scratch from battery changes. I have to keep taking off my Seidio innocase everytime I change the battery.
