Gionee Marathon M3

Gionee Marathon M3 is a dual-SIM smartphone which comes with a whopping 5,000mAh battery for epic endurance and a 5-inch TFT capacitive touchscreen display using LCD technology.

The device features a 5-inch TFT capacitive touchscreen with HD (1280x720 pixels) screen resolution which results in a pixel density of 294 PPI. Under the hood, it is powered by a 1.3GHz quad-core MediaTek MT6582 processor paired with 1GB of RAM, both of which you can see on plenty of smartphones that compete with the Marathon M3. The device runs Android 4.4 KitKat and is 104mm thick, which might seem like a lot but is quite normal for a smartphone with a huge battery that never dies out.

The device comes with an 8-megapixel rear camera with LED flash to capture images in both day and low light conditions, with autofocus support that enables quick capturing of every special moment. It also has a 2-megapixel front facing shooter for selfie lovers and those who communicate with friends and family in other cities or countries. The smartphone also has the capacity to record HD videos. The smartphone has 8GB internal storage capacity which can further be expanded up to 32GB via microSD card slot present on it. That's not counting the plethora of cloud services that allow users to offload their data online and then access them at any time as long as they have an internet connection.

Connectivity options include 3G, Wi-Fi 802.11 b/g/n, Bluetooth 4.0 and microUSB 2.0 port, enabling users to stay connected at all times. It also has dual-SIM support with dual standby. It is powered by a Li-Ion 5,000mAh battery which supports talk time up to 32 hours and multiple days of standby. It's possibly the largest battery capacity on a smartphone, with very few alternatives that can match the device.
