Samsung Galaxy Z Flip Battery Test Completed: Can Foldable Phones Match?

is an innovative little gadget: it turns and folds into a super compact size, and it looks cool.

While this is all great, we have now finalized our battery test for the Galaxy Z Flip. Yes, a little late, but better late than never.

Before we give you the results, we have to say that this phone comes with an unusual battery system: there are actually two different battery cells, one in the top half of the phone and another in the bottom half. Combined, they form a single 3,300 mAh unit.

First there is a small 930mAh battery at the top of the phone, then a much larger 2370mAh battery at the bottom of the phone. The two are connected via a flat cable through the hinge and act as a single battery unit with a total capacity of 3,300mAh. It’s nowhere near as big as the Galaxy S20 Ultra’s 5,000mAh, but that’s the price to pay for super-compact foldable phones.

So, without further ado, how did the Galaxy Z Flip perform in our battery test?

Navigation test

We start with the navigation and scrolling test, the least demanding on the phone. The same script runs on all phones that pass this test and all are set to the same brightness level to level the playing field. The test is performed over a Wi-Fi network.

And there, the Galaxy Z Flip serves us the first disappointment: at 8 hours and 26 minutes, the autonomy is just average, even a little below the average of the 2020 flagships. It is certainly not impressive at all. It is only comparable to the small iPhone 11 Pro which scores a little better at 8 hours and 40 minutes. All Galaxy S20 phones and other iPhone 11 series devices smoke the Galaxy Z Flip on this test, and it’s not even close.

YouTube video streaming

Next, we turn to something that most of us do on a daily basis: video streaming. This test focuses on watching YouTube videos and uses the same video playlist.

And in this test again, the Galaxy Z Flip is well below average: it only scores 6 hours and 40 minutes. It’s one of the worst scores of any phone we’ve tested so far in 2020, but it still beats the iPhone 11 Pro, which scored 6 hours and 27 minutes on the same test.

If you needed proof that the Z Flip doesn’t last that long, now you have it: it ranks well below the competition for two of the most common tasks these days. Get a phone like the Galaxy S20 Plus or the iPhone 11 Pro Max would be a much better choice if you value battery life (and your wallet). But these phones don’t flip or bend, at least not without breaking.

3d games

Finally, we test the battery life of the Galaxy Z Flip for 3D games. Quite honestly, it’s not a phone we imagine gamers would buy with that tiny screen, but let’s see how its battery works when a game puts extra load on the graphics chip.

And the answer is, the Z Flip does surprisingly well here! It’s not the best but it’s actually in the middle of the rankings. How can we explain this? Well the Galaxy Z Flip is powered by the Snapdragon 855+ chip which was last year’s fastest processor on the Android platform and this chip brings an improvement in particular to the GPU and of course its power efficiency. So gamers might not be disappointed with the battery life of this phone after all.

Final words

Ultimately, the Galaxy Z Flip is an innovative gadget that flips and bends, and that’s cool in a lot of ways, but it’s by no means a battery champion. For the most common tasks we do on our phones, browsing the web and watching videos, it ranks among the worst performing flagships. That’s not bad in itself as all phones have dramatically improved their battery life in 2020, but it’s certainly a far cry from a 2-day phone.

So there you have it, our Galaxy Z Flip battery test.
