The Sony Xperia 1 III is finally here, and it boasts a 4K 120Hz Display, but how does that translate in terms of Battery Life? Well, it does have an increased 4500mAh Battery, but is that Enough? Let's find out while comparing it to the MASSIVE 5000mAh cell S21 Ultra and Mi 11 Ultra, as well as the same sized battery cell OnePlus 9 Pro (4500mAh), and very well optimized iPhone 12 Pro Max (3687mAh) in this ULTIMATE Real Life Usage 100%-0% Battery Drain Test! The Sony is set to 4K while the rest of the devices are set to their native QHD resolution. All Androids are set to 120Hz refresh rates while the iPhone is stuck at just 60Hz. With FOUR Snapdragon 888's chipsets and an A14 Bionic chip, the results are VERY Interesting! All Phones are Set to the SAME Brightness (Using a LUX Meter). I Run through 15 APPS which include System Apps, Media Apps, Social Media Apps, Benchmark Apps (to simulate High Performance Gaming), and Games. Intervals are clocked every 30 Minutes and at each interval I show the Percentage of each phone as well as their Degrees in Celsius using an Infrared Heat Gun!
