The HTC Evo 4G is certainly a mighty Android smartphone warrior, but it has always been criticized for its ‘poor’ battery backup. A software update was always expected to add to its battery performance, but nonetheless it’s quite the pitiful same.

Japan’s Mugen Electronics have launched Mugen Battery Pack for HTC Evo 4G that impressively doubles the battery life of your Evo 4G. HTC Evo comes with a 1,500mAh battery pack, which is not sufficient to keep you going all day long.

However, with the 3200mAH HTC Evo battery pack, you can exploit your HTC for a whole day long. Dimensionally, a 20mm addition to the thickness of the phone should not affect it considerably considering its already big form factor.

Mugen Power batteries have better performance (higher capacity) and reliability (longevity & safety) than other brands. The superior performance improves run time, often doubling that provided by the original brand replacement. Thesuperior quality results in longer battery life and better protection of the powered device.

Earlier in June Muden released its first battery pack for HTC Evo 4G which featured a 1800mAh battery that no doubt boosted the battery backup of the device, but only by 20%. However, the newly released Muden HTC Evo battery pack goes beyond the 20% mark and helps to improve HTC Evo battery life by about 100%.

The HTC Evo battery pack case (HLI-A9292XL) will be available for sale through 13^th August for about $97. Click here to preorder now or just click here to know more.
