The Galaxy S21 is plenty powerful even with lesser specs than the S20.dialled back the RAM a bit from the
S20’s ridiculous 12GB, but the 8GB
inside the S21 should be plenty. Apple
has only 4GB in the iPhone 12, but
iOS 14’s optimizations make it seem
like there’s much more. Samsung also
beats Apple with storage, offering
128GB in the S21 compared to the
iPhone 12’s 64GB.
Battery life is a bit more
complicated. On paper, the S21
boasts a 4,000mAh battery versus
the iPhone 12’s 2,815mAh one, but
real-world results will be much more
important. The iPhone 12’s battery lifebested that of Android phones with
nearly twice as much battery capacity
in 2020, so I expect both phones to
make it though a full day of use with
ease. When it comes to charging,
both phones offer fast charging via
the included cable, 20 watts via the
iPhone and 25 watts with the S21.
They both offer 10 watts wireless
charging as well, and the iPhone also
offers MagSafe magnetic charging
via optional accessories.
Elsewhere, both phones have
sub-6GHz and mmWave 5G, and
Wi-Fi 6 for speedy connectivity, as54 Macworld • March 2021iPHONE
