A few days ago, the global variant of the OnePlus 15 was unveiled. It features a massive 7300mAh battery, allowing us to assess its durability.

Lover Of Tech compared this new release with the related Oppo Find X9 Pro, sporting a 7500mAh battery, and the iPhone 17 Pro Max, which has a 4832mAh battery. It’s worth noting that this is the SIM card version of the iPhone with a smaller battery. As observed, Oppo’s flagship won the extensive test by a significant margin. Despite having only a slightly larger battery than the OnePlus 15, its screen time was noticeably higher: 11 hours compared to 9 hours and 39 minutes.
Meanwhile, Apple’s flagship turned out to be the underdog, with a significant lag: only 7 hours and 38 minutes. However, it bears repeating that the eSIM version will be slightly more enduring due to a larger battery.
