P.S - Mine is a US variant.

      Jemmy, 18 Jan 2024Xiaomi note 13 Pro is better than Samsung Galaxy s 21 ultra... moreWhy?
      I'm considering buy used S21 Ultra as secondary android phone.

      Is today midrange like redmi note 13 pro better?
      spec wise it's doesn't looks like that

      or is this processor things with 7s gen 2 performance and stability > snapdragon 888/exynos 2100

                        The S21 ultra is a awesome awesome phone in every way I had the choice of the S22 ultra & the S23 ultra and I picked the S21 ultra and boy did I make the right decision
                        It has Unbelievable looks & feels beautiful in the hand
                        The screen is absolutely beautiful best I have ever seen with vibrant colors and sharpness unmatched by any phone out there
                        Cameras are as good as the newer models
                        If your thinking of buying this model phone do it you won't regret it

If you’re advertising for other brands doesn’t mean you should be spoiling others. Samsung is years ahead of other android makers. iPhone cap at 30w, you didn’t complain. Yet always complaining on Samsung. All this won’t make you succeed. Attacking others is not a way of advertising.

                              Battery life on this device is not soo good, I've had this device for just a week. some forums are saying its because the phone is new, I'm giving it an extra week if this rubbish doesn't stop i'll return it

                                this phone has to be the worst Samsung phone i have ever owned the battery is so bad when i unboxed it i set the phone up i plugged it into a wall socket and charged it to 100 percent after making a call and sending a txt the battery dropped instantly from 100 to 92 percent i literally could see the battery go down and so i sent it back to samsung under the warranty a couple of days later they sent it back saying they had tested the device and there was nothing wrong with it then i updated the phone to Android 13 they introduced a switch in the settings which paused the phone when it charged to 85 percent this was meant to preserve the battery life span so i can only charge it to 85 percent also after putting the apps i dont use into deep sleep the phones battery is still dropping down fast i am angry the phone has great specs but the should have put a 600 mah its over priced and over rated the most screen time is 3 hours and this is when i charge to 85 percent over a 5 days of charging to 85 and not 100. it feels like they rushed to get it on the market after watching a movie its gone from 85 to 56 percent rubbish phone i dont recommend because of the poor battery life and after every new update it gets even worse with them adding more and more things to the phone. over all im gonna sell it when my contract ends and get a new pay as you go and the phone will have 600 mah and no bloat. this phone has become with every new update more and more bloaty.

So therefore, this phone cannot support any charger that's higher than 25 watt.

                                      Also, I have tried my other chargers brand like my 45 watt Anker brick and 30 watt realme chargers and this phone seems only register it as 15 watt (fast charging).

                                      Or idk, I guess this phone can only register 25 watt charging with power delivery cables (Usb C to USB C
