OnePlus 15 vs Competitors Battery Test 🔋

These Battery Sizes are MASSIVE, but which will last longest between the OnePlus 15 (7300mAh), OPPO Find X9 Pro (7500mAh), Vivo X300 Pro (5440mAh), iQOO 15 (7000mAh), REDMAGIC 11 Pro (7500mAh), Samsung Galaxy S25 Ultra (5000mAh) and iPhone 17 Pro Max (4823mAh) in this ULTIMATE Real Life Usage 100%-0% Battery Drain Test?!?

All Phones are Set to the Exact SAME Brightness Level (Using a LUX Meter). If a phones display looks brighter or dimmer than another, it's due to my studio lighting OR because it dimmed due to overheating.

I run through 15 APPS which include System Apps, Media Apps, Social Media Apps, Camera Apps, Benchmark Apps (to simulate High Performance Gaming), and Games. Intervals are clocked at every 30 minutes and at each interval I show the percentage of each phone as well as their temperature in degrees celsius using an Infrared Heat Gun!
