One of the biggest issues that people seem to have with the Sony Ericsson Xperia X10 is battery performance. Yes, the Xperia X10 ships with a reasonably meaty 1500mAh battery, but the demands of that 4-inch screen and 1GHz Snapdragon processor means that most people have to charge their handsets every night.
We’ve previously outlined some tips that go some way to improving battery life, but failing that, the only option is going for a higher capacity battery. Mugen Power was kind enough to send over two of their third-party batteries for review, one with an 1800mAh capacity and another with a monstrous 3600mAh capacity. In part one of our review we mainly look at the design of each battery. Part two will be followed in a few weeks time that will give the battery test results and overall conclusions.
Mugen Power 3600mAh Xperia X10 Battery
First up is the higher capacity 3600mAh Mugen Power battery that retails for $96.95. The battery arrived with a black cover, for those with white Xperia X10’s a white cover is also available. There was also some paperwork that should be read before using the battery. It suggests that you need to charge the battery for 12 hours for the first time.
The battery comes in quite simple packaging. The battery sits in the black cover and this has a small piece of sponge behind it to prevent it getting scratched in transit. The usual warnings and warranty information is placed on the back of the packaging. The battery comes with a 6-month warranty.
As the codename (HLI-X10XL) suggests, the 3.7V 3600mAh battery is quite big and won’t fit into the existing housing. This is the reason why Mugen Power provides a back cover to account for the larger battery.
It’s difficult to get a sense of how much thicker this battery is when just looking at it alone. We have some comparison pictures later in the review that give you a better idea of the size.
Mugen Power provides back casings in both black and white colours. The black cover that we received is of a matte finish very similar to the existing housing.
The cover has been manufactured to fit the Xperia X10 perfectly. The cover fits into the Xperia X10 securely, an important point considering the larger size of the back cover.
Here we compare the original back cover with that from Mugen Power. You lose the Xperia branding on the back cover, but the holes for the camera and ‘flash’ fit well.
The plastic used by Mugen Power is a near perfect match for the original cover. The matte feel is also the same.
With the 3600mAh battery attached you can get an idea how much it sticks out over the original Xperia X10 battery. This is the main reason for the larger back cover housing.
Once the back cover is attached, it fits very snugly to the rest of the phone. This makes the phone obviously larger, we measured the total thickness of the phone at 19mm using this battery.
As mentioned previously, the covers have been manufactured to a high quality. It fits to the phone very well and will leave you confident that it won’t come off on its own.
This even extends to the front of the phone which sits flush with the casing.
The main holes for the camera lens and flash are the perfect sizes as can be seen in the picture below. There is no detriment to the quality of pictures taken given the indents surrounding the lens.
