Galaxy S21 Battery Test – Exynos 2100 vs Snapdragon 888 (May Update)

In today’s video we’re putting the Exynos 2100 vs the Snapdragon 888 in a head-to-head battery test. We’re going to run this drain test with some common apps and games and see which processor is the most efficient. We’ll also be keeping an eye on the temperature of both phones during the test to see if one heats up more than the other.

These are both the Galaxy S21 with 8GB RAM and a 4,000mAh battery. Brightness is set to 50% and all other settings are exactly the same. Both phones have a SIM (different networks) and the Snapdragon variant is a clone of my Exynos variant using Samsung Smart Switch). This is as fair as I could possibly make it with what I have on hand. All tests run for around 30 minutes.

I also did a 120FPS/120Hz Battery Drain Test here which is worth watching here.
