Galaxy S21 Ultra vs. iPhone 12 Pro Max Battery Test

After running multiple trials to make sure that we got it right. The battery test between the galaxy s21 ultra and the iPhone 12 Pro max is here taking a look at the spec sheets. Both of these phones are powered by energy, efficient, five nanometer processors. They both have similar screen sizes, and the big differences come down to their battery capacities, where the s21 ultra has a massive 5000 William hour battery compared to the iPhone's 3687, and then, of course, the refresh rate where the galaxy is being tested at 120 at its full 1440p resolution. While the iPhone is running at 60hz now, the s21 ultra's new display is supposed to be more efficient than last year's galaxy, but whether it'll be efficient enough to help beat the iPhone in this battery test. Well, let's find out all right, we'll kick things off in the phone app where, after going on the same one-hour phone call, the iPhone does better dropping to just 98 compared to the galaxy's 95.

Now, I'm always a bit skeptical of the reported battery percentage at least early on since it does seem, like some manufacturers tune in more for the sake of reducing people's battery anxiety than indicating the actual battery life, but we'll see how the phones do here in the messaging test where this time the galaxy does better cutting into the iPhone's lead within now. Just two percentage points behind. So I'm not sure if the galaxy actually did better there in that messaging test or if it was just the iPhone's battery percentage indicator. Finally, providing a more accurate estimate, but either way here in the email test, the galaxy does slightly better again with it now trailing the iPhone by only one percentage point. So a nice comeback by the s21 ultra we'll see if you can actually take the lead here in the browser test where, unlike that last email test this time, we're actually putting those CPUs to work where, after one hour, no it's the opposite result with the iPhone actually doing significantly better, creating its biggest lead so far pulling a full five percentage points ahead.

I really wasn't expecting that result. Both of these phones have pretty efficient five nanometer processors, but we ran this multi-day battery test multiple times and the results that we got here were always consistent. Anyways here on instagram we're scrolling through the home feed, just like you would in real life in theory, there should be more taxing on the galaxy, since it does have that 120 hertz refresh rates, but after one hour both phones perform identically with each dropping by seven percent so heading into the 16-hour standby. This is a close one. Let's see if the larger 5 000 million power battery can help the galaxy here, given that the screens are off, and it looks like it does, with the galaxy doing one percent better pulling within four percentage points as we work on YouTube now, just like with the screens we've calibrated the speakers on each phone to the same decibel count.

The 120hz refresh rate shouldn't be a factor here on the galaxy, but even then the iPhone still manages to do better. This was another result. I wasn't really expecting, but after doing a closer analysis of the speakers on these phones, I think that's where the difference lies. If you take a look at the galaxy's top earpiece speaker that speaker, grille is really slim. In fact, you could barely even see it here, while the iPhone's earpiece speaker, grille, is much bigger.

Thanks to that notch, which I suspect allows the iPhone speaker output to be lower while still matching the volume level of the galaxies. I did a demo of this over on Instagram at phone buff, so follow us over there. If you want to see that, I think seeing the demo will make it easier to understand, but the gist of it is, I believe that slim earpiece, speaker, grill, makes the galaxy speaker technically have to work harder in order to match the volume levels of the iPhones, which would obviously make it less power efficient. Of course, here in alto's adventure, the speaker isn't the only factor. There's also that 120hz refresh rate at full 1440p resolution, which combined cost the galaxy with it dropping by 15 points compared to the iPhone's 11 point drop, giving the iPhone a 9 point advantage as we work on this simulated navigation test.

Now in this test, the speakers aren't a factor. I don't believe that refresh rate is running at 120, hertz and really the big factors here are the GPS and the compass where, after one hour this time, the galaxy does significantly better cutting the iPhone's lead back down to just five points. Now here in Spotify. These speakers are the biggest factor again they're, both calibrated to the same decibel counts, measured from the center of the screen at an equal distance, where, after one hour, despite having a smaller battery, the iPhone does better once again adding two points to its lead in this camera. Snapchat test we're really pushing things to the limit having the selfie cameras on both phones, active, recording, video clips, which also taxes the microphone and then uploading those clips to the server where 28 minutes into it.

The galaxy s21 ultra calls it quits, just as the iPhone gets that 10 battery remaining pop-up. So there you have it a 10 percentage point difference which, at least according to this test is good enough to last the iPhone and additional 1 hour and 15 minutes in web browsing, or it can be used for 1 hour and 25 minutes of scrolling through Instagram. So, while it's not night and day, it is pretty significant for those of you wondering the iPhone made it through Snapchat with four percent remaining, which allowed it to survive the app cycle test, where we open and close these apps repeatedly for a full 20 minutes, so a clear win for the iPhone and just an impressive level of efficiency. Given how small that battery in the iPhone is compared to the galaxies but anyways. That is it for me in this video.

Thank you for watching and as always I'll see you in the very next episode you.
