Gionee has announced it will be launching the Marathon M5 smartphone in India on Tuesday. The handset debuted in China earlier this year priced at CNY 2,299 (roughly Rs. 23,000). The Gionee Marathon M5's claim to fame is its long battery life. It comes with two 3010mAh batteries, taking the total to 6020mAh. The company says the batteries should last up to 4 days. It also features an extreme mode that can boost standby time at 5 percent battery life to 62 hours. As expected, the smartphone supports reverse charging, which allows users to utilise the Marathon M5 as a power bank to charge other devices. It also features a fast charging system, but no details have yet been provided about how long it will take to completely charge the dual battery setup. The Marathon M5 also runs on Android 5.1 Lollipop, and is a dual-SIM dual standby smartphone with 4G LTE functionality on both SIM card slots. It features a 5.5-inch HD (720x1280 pixel) Amoled display, and is powered by a 64-bit 1.5GHz quad-core MediaTek MT6735 SoC, coupled with 2GB of RAM. It sports 16GB of built-in storage that can be expanded via microSD card (up to 128GB). It features a 13-megapixel rear camera, and a 5-megapixel front camera. It measures 152x76x8.55mm and weighs 214 grams. The Gionee Marathon M5 was launched alongside the Elife E8 back in June. The Elife E8 was launched in India last month at Rs. 34,999.
