In late 2026, Infinix remains a dominant force in the budget and mid-range segments by prioritizing “marathon” battery endurance. For many users, the most critical feature of a smartphone is its ability to last multiple days on a single charge. Infinix addresses this by equipping several of its HOT and SMART series devices with massive 6,000mAh batteries, a capacity that significantly outpaces the 5,000mAh industry standard.
The secret to Infinix battery success lies in the synergy between high-capacity cells and power-efficient processors like the MediaTek Dimensity 6000-series and Helio G-series. These chipsets allow the device to optimize battery life by managing background tasks effectively while still providing smooth performance. Furthermore, Infinix has introduced Safe Charge and AI Power Management features that learn user habits to extend the physical lifespan of the battery.
This list details the 7 best Infinix phones for the longest battery life in late 2026, focusing on the latest models that offer the highest mAh ratings and the best energy efficiency. Whether you need a 5G workhorse or an ultra-budget endurance champion, these selections provide the most “screen-on time” in the current Infinix catalog.
