Consumers always take into account the importance of battery capacity whenever purchasing a smartphone. The 2700mAh battery in the Samsung Galaxy S4 can be replaced now with the available Mugen Power 5500mAh battery that can extend the smartphone's life for days.

The fresh Mugen Power accessory guarantees that the Samsung Galaxy S4 battery life will be doubled and can last for 3 to 4 days. A rear cover comes with the Mugen Power battery as well as a leather case for protection since the larger battery capacity puts in some thickness to the smartphone.

The massive Mugen Power 5500 mAh extended battery for the Samsung Galaxy S4 has a price of $89.50 in black or white colour choices. The smartphone accessory will start shipping in the later part of July with free delivery worldwide.

According to Mugen Power, the estimation of 3-4 days battery life for the 5500mAH Samsung Galaxy S4 battery still depends on the owner's smartphone usage, ranging from apps installation, e-mailing and Web site browsing. However, the manufacturer assured that the battery will correspond to the Samsung Galaxy S4 stock battery voltage, and owners can still utilise the NFC feature on the device.

Mugen Power is recognised for its quality brand of extended batteries designed for devices. The manufacturer only uses premium Li-ION in producing their batteries as they match the device's voltage and specs to become a suitable battery replacement.

This is not the Mugen Power's first time to release an extended battery case. Mugen Power has previously announced the availability of the 4500mAh extended battery case for the Nexus 4 smartphone in which users can experience up to 3x more battery life on the Google-LG device.
