The OnePlus 13T has made headlines with its 6260mAh glacier battery, the largest in a compact flagship phone. This new device, launched in April 2025, promises unmatched battery life, outshining big names like the iPhone 16 Pro Max.
According to FoneArena, OnePlus claims its latest phone “leads by a large margin” in battery life, even when compared to the iPhone 16 Pro Max, which is known for its strong endurance.
OnePlus China head Louis Jie highlighted that users can expect a full day’s use on a single charge, with at least 7 hours of continuous playtime-without needing a power bank or a power-saving mode.
In direct comparison, the iPhone 16 Pro Max features a 4685mAh battery and lasts 11 hours 34 minutes in a recent battery drain test, topping previous iPhone models. However, the OnePlus 13T’s larger battery, combined with efficient hardware like the Snapdragon 8 Elite chip and a power-saving LTPO display, helps it surpass the iPhone’s performance in similar tests.
A recent YouTube battery drain test compared the OnePlus 13T, iPhone 16 Pro Max, and other flagships. The OnePlus 13T consistently retained more battery after heavy gaming, video streaming, web browsing, and social media use. While the iPhone 16 Pro Max performed well, the OnePlus 13T lasted longer, especially during demanding tasks6.
The OnePlus 13T also supports bypass charging-a feature that lets you power the phone directly from the charger while gaming, reducing battery wear and heat. Fast charging up to 80W ensures you spend less time plugged in.
With a compact 6.32-inch display and weighing just 185g, the OnePlus 13T offers a rare combination of portability and battery endurance. For Indian users who want a phone that truly lasts all day, the OnePlus 13T stands out as the new battery champion among flagship smartphones.
