The S21 Ultra is finally here, and it packs a punch in performance with the new Snapdragon 888 chipset, but can that performance translate to great battery life with it's HUGE 5000mAh Battery? Let's find out while comparing it to it's older cousin, the Note 20 Ultra (4500mAh), Snapdragon 888 buddy - Xiaomi Mi 11 (4600mAh), Google hater - Huawei Mate 40 Pro (4400mAh), and efficient iPhone 12 Pro Max (3687mAh) in this Real Life 100%-0% Battery Drain Test! ALL PHONES SET TO WQHD+ (native) Resolution and 60Hz REFRESH RATES to keep things even! With TWO Snapdragon 888's, 865+, Kirin 9000, and A14 Bionic Chipset, 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!
