realme C21 debuted in April also in Italy and immediately positioned itself as the best among low cost devices. Accomplices of this one huge battery, a really giant screen and a ridiculous price. But all that glitters is not gold: if on the one hand we cannot expect everything from this device, on the other hand we cannot even skimp too much. And the brand seems to have forgot some charging power in the drawer. This at least what DxOMark tells us.
realme C21 is reviewed by DxOMark regarding the battery and autonomy: excellent for its resistance, but painful for the charging speed
DxOMark experts have decided to find out how things stand with the autonomy of the economic smartphone realme C21. Its battery, with a capacity of 5000 mAh, has undergone a series of tests, after which experts have issued their verdict.
realme C21 equips with a 6.5 "display with a resolution of 1600 x 720 pixels. The "heart" of the device is the processor MediaTek Helio G35, built using 12-nanometer technology. Despite the 5000 mAh battery, the device does not support fast charging technology: the maximum power he can count on is 10W.
They want us 3 hours and 7 minutes to charge completely the smartphone, which is extremely much by the standards of 2021 devices. In 1 hour and 50 minutes, the realme C21 charges up to 80%. With standard operation it can work up to 2 days and 9 hours, and in the moderate use mode (2.5 hours per day) it can last 83 hours. In this case, a uniform discharge process of the device is observed.
According to experts, realme C21 demonstrates a extremely ineffective charging algorithm: It takes much longer for the device to recharge the battery to 100% than other representatives of the economy class. In the overall standings, realme C21 took 32nd place in the overall standings, earning 62 points. But in his class he is al fifth place.
