When it debuts in China later this week on April 24th, the OnePlus 13T will feature a 6,260mAh battery, as spotted by Notebookcheck. That’s a lot of capacity for a compact phone with a 6.32-inch screen. For comparison, the 6.3-inch Google Pixel 9A has a 5,100mAh battery, while the 6.3-inch iPhone 16 Pro has an even smaller 3,582mAh battery.
