Samsung Galaxy Z Flip 4 battery - 'Til your good is better and your better is best

The Galaxy Z Flip 4 has been on the market for a few about a year now and has already moved past its initial release hype. Аctually, the successor is already out, and you can check out everything about the Galaxy Z Flip 5 in our dedicated review. The latest foldable flagship phone was unveiled at last year's Galaxy Unpacked event and this puts the Galaxy Z Flip 4 in a peculiar place.

As the best-selling foldable phone, the Z Flip family is very important for Samsung and also for Galaxy fans over the world. One area where the Samsung foldable phone has seen significant improvement over the years is battery life.

Does the Galaxy Z Flip 4 have a bigger battery than its predecessor?

The answer to this question is a firm yes! Fortunately, Samsung has listened to the users and tech reviewers and has decided to address the battery life in the Galaxy Z Flip 4. The phone now comes with a 400mAh bigger battery than its predecessor - the Galaxy Z Flip 3.

How much battery does the Galaxy Z Flip 4 have?

The battery capacity of the Galaxy Z Flip 4 is rated at 3,595mAh which results in a typical capacity of 3,700mAh, which, as stated above, is 400mAh more than the battery capacity of the previous version. We're talking about two separate battery cells inside (due to the phone actually featuring two parts folding into each other).

This 12% increase in the capacity results in longer battery life, adding almost 3 hours on top of the Z Flip 3 result in our Video Browsing test, and around 2 more hours in the Web Browsing benchmark. The Gaming benchmark returned a strange result, maybe due to aggressive thermal throttling, we might run this test again to clarify things.

Below you'll find the benchmarks along with some comparison with other more "rigid" flagships such as the iPhone 13 and the Galaxy S22, as well as a comparison with the latest addition to Samsung's foldable range, the Galaxy Z Flip 5.

Does the Galaxy Z Flip 4 have wireless charging?

Another positive answer here! Yes, the Galaxy Z Flip 4 supports Samsung Fast wireless charging 2.0. This wireless charging standard from Samsung supports 10W+ charging power, and is available on the Samsung Wireless Charger Stand and Wireless Charger Duo Pad. Other Qi-certified wireless chargers will also work with the Galaxy Z Flip 4.

Now, as far as normal, wired fast charging goes, the Galaxy Z Flip 4 has upgraded the supported charging power to 25W (the predecessor supported only 15W fast charging), which is good news for practically everyone, especially given the higher battery capacity.

Does the Galaxy Z Flip 4 have reverse wireless charging?

Same as the above - given that the Z Flip 3 already supports 4.5W reverse wireless charging, and the Galaxy Z Flip 4 offers the same PowerShare support as its predecessor. You can share power with other compatible phones or charge your accessories (if they support WPC Qi wireless charging) such as Galaxy Buds, Galaxy Watches, etc.

Does the Galaxy Z Flip 4 come with a charger in the box?

That ship has sailed, sadly. The Galaxy Z Flip 4 comes with a USB Type-C cable in the retail box but no charging brick. You'll need to use an old one (Samsung advises using only compatible chargers from the brand), or buy one separately.

Conclusion

Well, there you have it! All Galaxy Z Flip 4 battery questions have been answered! It seems that Samsung really made a substantial upgrade in the battery life of the Z Flip 4 - a much needed one actually, and one that will result in maybe the greatest quality of life improvement in comparison with the previous generation. The Galaxy Z Flip 5 is out now, and you can check how it stacks against its predecessor in the bench graphs above.
