Comparing the battery life of the iPhone 17 Pro Max and the OnePlus 13 involves looking at several factors, including battery capacity, charging speed, and overall usage efficiency.
iPhone 17 Pro Max
The iPhone 17 Pro Max is rumored to have a larger battery compared to its predecessor, the iPhone 16 Pro Max, which had a 4685 mAh battery. This increase is suggested by the thicker design of the iPhone 17 Pro Max, measuring 8.725mm compared to the 8.25mm of the iPhone 16 Pro Max[1][7]. While specific battery capacity details for the iPhone 17 Pro Max are not yet confirmed, the increase in thickness is believed to accommodate a larger battery, potentially enhancing battery life[7]. Apple is also rumored to introduce faster charging speeds, possibly up to 35W, which would be an improvement over the current models but still slower than some Android competitors[4].
OnePlus 13
The OnePlus 13 boasts a significant 6,000 mAh battery, which is larger than most flagship phones, including the iPhone 16 Pro Max[2][3]. This large capacity, combined with efficient battery management and silicon-carbon chemistry, allows the OnePlus 13 to offer impressive battery life, lasting up to nearly two days with moderate use[5][8]. Additionally, the OnePlus 13 supports fast charging with an 80W wired adapter, allowing it to charge from 0% to 100% in about 40 minutes[2][5].
Comparison
- Battery Capacity: The OnePlus 13 clearly has a larger battery capacity at 6,000 mAh compared to the iPhone 16 Pro Max's 4685 mAh. If the iPhone 17 Pro Max does indeed have a larger battery, it still might not match the OnePlus 13's capacity.
- Charging Speed: OnePlus offers faster charging speeds with its 80W wired charging, while Apple's fastest charging speed is currently 27W for the iPhone 16 Pro Max, with rumors suggesting an upgrade to 35W for the iPhone 17 series[3][4].
- Efficiency and Usage: Both devices are known for efficient power management, but the OnePlus 13's larger battery and fast charging capabilities give it an edge in terms of raw battery life and recharging speed.
Overall, while the iPhone 17 Pro Max may offer improved battery life due to its potential larger battery and efficient power management, the OnePlus 13's larger capacity and faster charging speeds make it a strong competitor for users prioritizing battery performance.
