Chinese manufacturer Gionee is continuing to build its impressive roster, delivering a set of capable smartphones in and out of China. The latest handset to make the jump to an international release is the Gionee Marathon M5, which recently launched in India.

According to a report from GSM Arena, India is the model's first international destination after its initial release in China last June. The Marathon M5 will likely make waves not just with smartphone users who are acquainted with Gionee as a brand, but to those who value battery life above most other specs.

The most prominent feature of Gionee's latest handset is its dual battery setup, which means the handy phone is equipped with two 3,010 mAh battery cells to a total of 6,020 mAh of battery capacity. This is an incredible feature for people constantly on the go as the company claimed the smartphone can run for up to four days without charging.

Furthermore, the Marathon M5 can be switched to extreme mode when it hits five percent of battery left, which increases standby time to up to 62 hours. The Gionee handset can also be used for reverse charging, as a power bank to charge the owner's other devices.

From the looks of it, Gionee has outdone itself in terms of battery capabilities, but the smartphone's other features seem to be decent as well. Under the hood, a MediaTek MT6735 SoC with quad-core 1.5GHz CPU powers the device. Packing 3GB of RAM and 32GB of internal storage, the Marathon M5 has a 5.5-inch AMOLED screen with 720 x 1280 resolution.

Other specs include a 13-megapixel rear camera, five-megapixel front shooter, dual-SIM support and color options of white, black and gold. It runs on the Android 5.1 Lollipop-based Amigo 3.1.

The Gionee Marathon M5 is priced at INR 17,999 or $270.

The company has been slowly developing its expansion to India, with the first made-in-India handset getting released last month, according to a report from My Digital FC. Gionee is reportedly planning to begin sourcing in the country as well.

"Right now we do only phone assembly," Gionee India country CEO and managing director Arvind R. Vohra. "However, in due course, we plan to bring in our vendors (from China), who would help us to make products locally. At least six sets of components including packaging, chargers and plastic parts can be sourced locally. ... Moreover, we may also look at couple of more locations to make phones within the country. We have capacity of about half a million and once we exhaust that, we would have to look at other options."
