Samsung Galaxy A31 VS Samsung Galaxy A21S VS Samsung Galaxy A51 - Battery Drain Test! (2020) By Matthews Tech

What is up guys today we're going to be doing a battery drain test of the galaxy a21s, the galaxy a31 and the galaxy a51. So you have 5 000 William battery 5000 William battery 4 000 William battery. So let's go ahead and boot these up they're all charged to 100. So I'm assuming it should go. Oh well, this one's already on. Is it still at 100 yeah, this one's still at 100, so I'm assuming it should go a21 s should be first, then a 31 second, and then the a51 should be.

Third, I'm going to start our stop watch here and let's go ahead and start with a YouTube playlist here. Just let everything play on auto all right guys, so we're at two hours and 13 minutes uh here so see. The a51 is at 83 percent, which is pretty good 87 on the 831 and the 21s is at 79. So pretty interesting here. All right guys we're at the four-hour mark here.

So, let's go ahead and check, starting with the galaxy, a 21 s, 58, so not doing as well as I thought it was going to do a 70 on the a31, and we're at 66 percent on the a51. So let's go ahead and back out and let's go ahead and go to social media application, Instagram and we'll go ahead, and let that run here all right guys we're at the six hour and one minute mark on the a51 we're at 51, 31 57 and on the a21s we're at 37 percent uh. So I'm going to go ahead and open the Chrome browser. It's something I like to do and just let that play or just let that be open, and we'll come back all right, guys, we're at seven hours and 33 minutes of screen on time here. So 851 is at 44 49 on the a31, and it's looking like the a21s is almost done here at 23, so we're going to keep going we're going to do a heavier uh game like Call of Duty mobile here and let that run and see how that does alright guys, so we're at nine hours of screen on time and the a21s is about done here, uh, which is pretty good.

So we do have only a 51 31 and on the a31 we have 36. So let's go ahead and just try to open up an another playlist and just check that out all right guys we're at five percent on the a51 at 11 hours and 33 minutes of screen on time. So excellent screen on time on the 51 and the 31 is still going pretty strong at 14 all right guys, so we're at the five percent mark on the a31, and it is pretty impressive. Uh you pretty much uh can almost get 12 hours of screen on time uh on this phone. So I think all of these phones did great uh.

The a21s did not do as good as I thought it was going to do. Maybe it's because of the chip um, that's what I'm guessing, but I was almost right so very, very good for Samsung's uh budget and mid-range lineup uh this year. So you get some solid battery life even with the worst one um. You can still get through a whole day with this uh, no problem, if not a day and a half again, if you're, just like really light. So thanks for watching I'll catch, you guys in the next one.
