Review on Factory Unlocked Samsung Galaxy S21 Ultra 5G Android Phone with 128GB Storage by Adisorn Srisawam ᠌

According to the manufacturer, the battery capacity is 5000 mAh, but a footnote on the official Samsung website indicates 4855. But even that doesn't matter! In fact, the application determined the design capacity of 4855 (I attach a screenshot from the application), but the actual one is even less. Charged from 0 to 100% when the phone was on, but did not use it while charging, everything was turned off, just to make the application work. Then I turned off the phone and charging continued for another 15 minutes. As a result, when I turned on the phone after a full charge, the application showed 4443, and the tester 4687. I'm not special, but I thought that when the charge reached 100%, the application would no longer take into account the charge, so I turned it off, and the battery still continued to take current until the controller turned off charging and the current dropped to zero. Total with all the stretch turned out what happened.
