So I found this battery on Amazon about a week ago for $12.99.. Ordered it and I am extremely impressed. Running Stock Rom + Root, constant use daily.I was really getting pissed off with the battery that came with the phone, it just doesn't do it justice.

Pro's - Been using the phone (50% Brightness, Downloading videos, youtubing, texting, phone calls, tinkering with GO Launcher stuff, almost played through a whole game of Words with Friends) Came off the charger at 3 P.M. today, legit screen on using the phone action about 4-5 hours tonight and it's now 11:25 P.M., battery is just hitting 65%! Extremely impressed with the performance of this battery and would recommend it to anyone that needs some extra juice.

Cons - It makes the phone about twice as thick towards the bottom half (I actually like this, it makes it much easier to hold on to and just grip in general). Also adds a significant amount of weight to the phone but nothing annoying, just saying.

UNSURE - Not sure about the NFC Capabilities of the battery, no one around me here has a phone with NFC so I can't test it... Honestly for the performance I could give a S*** less about NFC whether I keep it or lose it.

Just got an extended battery myself. Yeah it's thicker but using a phone all day without worrying about charging it, worth it for me.

Yeah, I just ordered this one too.

I had one on my captivate and I really liked it.

What does it matter if your phone is thin but you keep getting warnings that you need to charge it?


On my captivate if I got down to half of the battery with the larger battery I didn't have to worry, I had good 8 hours of use left.

Just confirmed it does NOT have this boot-loop issue common with the aftermarket batteries. Operates the exact same as the stock battery, still unsure of the NFC capabilities.

just received mine yesterday over 20 hours still 65 percent battery remaining. Will post a screenshot when the battery gets to 10 percent.

Sorry, but I think GTmax stuff is not that good, I purchased 3 batteries made by GTmax, there is no description of mA with just some generic label. Also, out of the 3, 2 were junk lasting only about 10hours with minimal use. Only one battery was decent, pretty close to OEM.

Also, looking at the battery debug info *#*#INFO#*#*, these batteries are more volatile than OEM, as the amps and temperture fluctuate more than normal.

Good Battery Possible Bad Cover?

I turned my phone off to put this new battery in. I fully charged it before turning it on.

It lasted 42 Hours before it died.
I was running Bluetooth, Pandora and Wifi Medium-Heavy Duty.

So the battery seems good, But it seems the back cover wasn't crafted all that well UNLESS I just got a bad one. It seems like a corner of it won't stay pressed down. Its not a huge gap, but it is somewhat noticeable.

Is anyone else think that their back cover doesn't fit all that well or is it just me?

Can someone post some pics of this on your phone?

The pics on Amazon don't show it on the phone and don't show a side-view of the new back cover.

...nevermind, pics in first few posts. company blocked the images

    Awesome price! Great buy for trip battery.

    Sadly with that thickness, I would rather club baby seals :(

    Nice find, going to have to think about this buy some more.

    Here are some pics of the phone with the extended battery and the bumper case from ebay. Sorry for the quality of the pics, they were taken with an htc hero:D.
    It looks really good in person and the bumper really adds some welcomed grip with minimal bulk. Overall the phone feels good to hold with one hand and it offers some protection to the corners in the event of a fall. The case and the battery cover are almost perfectly flush. As for battery life I'm getting between 36-48 hours depending on the use. Keep in mind that I only use this battery when I'm on call and /or know I'll be more than 1 day without being able to charge because otherwise the stock battery lasts me through a normal day. That being said I'm gonna try t out during a normal day to see how long it goes, heck I may even like it so much that I may ditch the stock batt:D!!!

    Edit: I bought it from ebay from the link posted in the OP!!
