Smartphones are getting smarter, however, to keep them running uninterrupted manufacturers are bundling batteries that last for a day or two. One may argue that this is fine, as generally phones can now be charged via USB port of PCs or laptops. However, it can be sometimes annoying if you are in the middle of an important call and the battery dies.
This is where a high capacity battery comes in handy. One such manufacturer of high capacity batteries for smartphones is Mugen Power. A familiar name for aftermarket batteries. This time we are testing the Mugen Power 3900mAh extended battery for Nexus S i9020T.
The standard battery of Nexus S is rated at 1500mAh that lasts for somewhere around 16-20 hours on 2G. But the extended battery by Mugen Power is a whopping 3900mAh, that’s more than twice the stock Nexus S battery.
The extended battery comes in a standard packaging with a battery door with NFC chip integrated. The battery door is pretty average without anything written on it unlike the stock battery door that mentions Google and Samsung on the battery door. As compared to stock battery door, this one looks pretty average. The battery door does not hamper any of the phones functionality like the camera or the buttons. It fits snugly to the phone and is available in white and black colours.
Adding the extended battery to the phone makes the Nexus S bulky, however the phone fits in to the hand pretty nicely. If you are using any protective case for Nexus S, then of course, you will not be able to use it with the extended battery.
On the performance front, Mugen Power requires you to calibrate the battery. Calibration includes charging of battery for 12 hours multiple times in order to achieve the optimum rated capacity. If you plan to use both the stock battery and the extended battery, Mugen provides an Android app to swap the batteries easily.
The battery delivered an uptime of almost 2.5 days with EDGE connectivity on, moderate calls, using phone applications and few minutes of gaming. This is indeed a good performance by this battery that makes you go on with the smartphone without worrying about the charge.
Mugen Power has priced this battery for Rs.5,318. A bit costly, but a great utility for people who use their phone more and want days of connectivity without re-charging.
