OnePlus 15 Reigns Supreme in Battery Tests
18 Feb
Summary
- OnePlus 15 excelled in all battery life tests.
- iPhone 17 Pro Max tied with OnePlus 15 in general use.
- Testing involved video playback and general usage scenarios.

The OnePlus 15 has secured the top spot for smartphone battery life, earning a ZDNET Lab Award. This device outperformed 16 other phones from major brands like Apple and Google in comprehensive testing. Its battery performance was particularly outstanding in video playback and general usage scenarios.
The iPhone 17 Pro Max demonstrated impressive battery longevity, notably tying with the OnePlus 15 during general usage testing. Apple's latest iPhone lineup collectively showed strong battery averages, closely following OnePlus. This success is attributed to Apple's efficient background task management and substantial battery capacity in the Pro Max model.
Testing involved two methods: continuous YouTube video playback with screens at 100% brightness and a 30-minute general usage simulation including social media, gaming, and video calls. While the OnePlus 15 stood out, other devices like the Motorola Razr and Google Pixel 10 Pro Fold showed less capable batteries in comparison.
