The Samsung terminal arrives with a slightly smaller battery, of 5,000 mAh, and with a 15W load. As we pointed out in its analysis, you can reach the end of the day without any problem, the autonomy of this Galaxy A21s stands out from the competition.

Processor and memory: MediaTek vs Exynos

The brain of the Redmi 9 is the MediaTek Helio G80, a processor that will not give you problems on a day-to-day basis. It is a device that moves fluently in basic tasks, you can also take advantage of somewhat more demanding games and applications. You can find it in versions of 3 GB and 4 GB of RAM, 32 GB, 64 GB and up to 128 GB of storage that you can expand with the help of a microSD card.

Despite being quite inexpensive, they enjoy NFC connectivity, which allows you to pay in all types of establishments together with applications such as Google Pay and transfer files easily and quickly. Nothing to reproach either of the two in this section.

We gain a little more resolution in your panel, also more ease with the performance of your processor. In the long run, and although the difference is small, the Helio G80 could give us a little more life.
