Ultimate Battery Showdown: OnePlus 15 vs. Oppo X9 Pro & More 🔋

Four 2025 flagships, one brutal battery drain test.
The OnePlus 15, Oppo Find X9 Pro, vivo X300 Pro, and Xiaomi 17 Pro Max all start at 100% — but only one makes it to the end. From video playback to gaming and camera use, every minute counts, and it gets more and more intensive.

I put a lot of effort and time (and a lot of $) into my content. If you like what I do, you can help me be able to get my hands on newer devices faster and keep creating. Thanks in advance!
