The ongoing smartphone wars has seen various handset manufacturers trying to outdo each other by offering devices that feature the best display’s, which in turn are powered by powerful processors with multiple cores. Trouble is this can sometimes be at the expense of battery life but an upcoming Lenovo P770 smartphone will feature Android 4.1 Jelly Bean with a massive 3500 mAh battery.

It seems as Electronista are reporting the company will be using the handsets battery performance as one of the handsets main features when it is released. The power pack will probably beat any other unit that is currently available in the smartphone market, with the Samsung Galaxy Note 2 using a 3,100 mAh unit, Droid RAZR Maxx HD with a 3,300 mAh, and the Galaxy S3 uses a 2,100 mAh.

Other images of the leaked smartphone show the device to have the usual touchscreen that most smartphones use, and sized at 4.5-inches with a resolution of only 960 x 540. This is set to be powered by a 1.2GHz dual core MediaTek MT6577 processor with 1GB of RAM.

There is also an eight megapixel camera on the rear with the smartphone expected to be launched with Android 4.1 Jelly Bean on board. Considering the rest of the specifications for the Lenovo P770 that massive battery should provide many hours of talk time and anything else you want to throw at it.

The device is expected to launch in China first and priced at around 1,700 Yuan, which is around $270 so if the handset makes it to other regions the company will be pushing the P770 at the mid-range market, but Lenovo is better known in the West for its PCs so it remains to be seen if Europe and North America will ever see the device.
