Introduction
The Gionee Marathon M3 was a smartphone launched in November 2014, during a time when battery life was becoming a key differentiator in the mobile market. Positioned as a budget-friendly option with an impressive battery capacity, it was aimed at users who prioritized staying connected without needing frequent recharges. Though now discontinued, it remains a noteworthy device for its time, particularly due to its ability to extend talk and standby times far beyond many of its contemporaries.
