This is the battery that should have been supplied with the new phone. The original battery was terrible. It would only last 2 hours and need to be plugged in. I also like the app by Mugen that monitors the battery status I highly recommend this battery for this phone. It lasts all day.

Longer lasting higher quality battery than OEM 1620MAH Tests run

14 February 2013

Jay

This battery works great! I received it 2 weeks after ordering. I have concluded it lasts 3-5 hours longer than the 1620MAH OEM battery, this depends upon user usage. 30+hours with light use and 7-9hours under normal use. I charged the battery for 12 hours x5 cycles per the instructions that came with the battery.

Great battery, lasts long time. :)

I've had the Mugen batt. installed for.. a few months now? Still works great, lasts all day. I was cautious about buying at first, since it's a little pricey, but it's worth it.

Definite improvment over the OEM battery

5 July 2012

Al

The 1900 Mugen arrived in the mail much quicker than I anticipated. I followed the break-in instructions and am pleased when comparing the Mugen to the OEM battery. I had to keep a charger in my office as the original battery would only last until 1 pm or 2 pm. With the Mugen, my HTC Rezound is up and running all day and I usually don't charge it until breakfast the next day. Another advange is that it charges VERY quickly.

Great Product

I had the super brick extended battery for my rezound and wanted to go back to my standard size back but still wanted to get some extended life. I stumbled across this product and went for it. The battery arrived promptly and in great condition. I have no complaints what so ever about this product. It lasts me longer without compromising the size. I love it and you would be well to purchase this if considering it an option.

Received the battery (overseas) in 2 weeks. Not bad! Packaging was fine. Big thing here is performance to the stock battery, and this battery is a significant improvement. I've seen pretty stable performance since the first few power cycles (a slight decrease since initial use, though), which typically last anywhere from 36-40hrs with moderate (multiple calls, games, internet browsing, tethering, bluetooth, etc) use. This battery is WAY better than the factory battery. Would like to see it last a full 48hrs without a recharge, but this is probably wishful thinking, but 40 hrs works for me!

I'm running a rooted HTC Rezound on ICS 4.0.3 (BAMF), stock BAMF kernel. Will probably see some improvements as more kernels become available for ICS on the Rezound.

Thanks Mugen!

Works perfectly on my HTC Thunderbolt, got it in a week!

Patrick F

I was a little hesitant to purchase this product because I have an HTC Thunderbolt and this battery is for an HTC Rezound. I read online that they use the same battery, so I took a chance.

I am sure glad I did. This battery lasts forever. I followed the easy instructions that came with it for maximizing the charge, and it definitely worked.

I asked for "standard shipping", and my battery came to Washington State in 1 week!

Good Replacement Battery

3 June 2012

Don

The battery arrived more quickly than I expected coming from overseas to the U.S.
The battery fits perfectly in the Rezound and allows the back cover to fully close with no problems. I have not experienced any over heating problems either during charging or while using the phone with this battery.
After following the recommended break in procedure I am getting about 2+ more hours of actual use time versus the OEM battery. It seems to be getting a little better with each charge but time will tell. It seems to hold the charge better from 100% to 75% and then again from 40% down to 10%. This has definitely been a better purchase that the cheap after market batteries that I bought on EBay that don't even last as long as the standard battery.
