  1. I have Realme C21-Y, it has 5000 mAh, the first day i got the phone I installed call of duty. I was playing call of duty and my battery lasted for 13 hours. But these phones are like 2-4 times stronger than mine

  2. If 11 pro max dies at 8hrs 41 mins leaving the S21 Ultra with just 8% power difference between the capacity is 1031 mAh. What if Apple comes with 5000 mAh Samsung will need to get somehting with almost 6000 mAh to beat that lol (No offence am an Apple fan ;D)

  3. That's nice but also not really conclusive… I've seen videos with totally different results… usually more in favor of the iPhone…and one where the 12 ProMax beat 11 ProMax… Maybe each phone is a bit different from the next same unit..🤔

  4. The Samsung galaxy S21 ultra actually wins! This is because The Samsung galaxy Note 20 ulta had 8 hours 41 minute 21 second, and the samsung galaxy S21 ultra had 8 hours 41 minute 23 seconds, it's just 2 seconds defiance,

  5. I have a phone is laundry cool

    phone powers
    the battery dies lasts a whole 26 hours and 50 seconds
    My phone is charging 70% faster to get 100%
    Any games and apps works
    Apps and games downloading 90% faster to get 100%
    If you watch video 1 hours battery still alive
