Hi everyone, I purchased this 3500MAH HTC Evo 3D Battery with black back plate two weeks ago. I ordered from here: 3500mAh Extended Life HTC Evo 3D Battery | AccessorySwamp.com I ordered, $43 buck out the door cause i live in california. I installed the battery and backdoor, immediately i noticed the texture of the backplate, and the grip it provides. I weighed the AccessorySwamp battery in one hand, and I have a 3500MAH Seidio from my HTC Evo 4G, the AccessorySwamp battery actually felt larger & heavier. I calibrated the AccessorySwamp battery, ran it through cycles. Yesterday I charged the battery over night, and unplugged it at 8AM. I used the phone moderately, using internet here and there, watched a few youtube videos. listened to 2 90 minute long pod casts, and streamed about 2 hours worth of Google Music over 4G through a bluetooth speaker. I also used the GPS for 15 minutes. While doing all this, i have 2 email accounts set up, set on auto receive every 30 minutes. With all this being said, i am not yet a root user, but I plan to root this week. My phone ended up dying after 1 day, 23 hours and 30 minutes... I almost put 2 days of unplugged up time on this phone, no problem. I would have taken screen shots, but i'm not rooted yet. I'm going to root my phone, test the battery again, and then update this post. stay tuned for more info on this battery... What other tests should I run on this battery?
