Galaxy Z Fold 6 and Z Flip 6 may not get a charging speed upgrade

Samsung's next flagship foldables might bring larger batteries than their predecessors, but they may not come with an upgrade in charging speeds.

The Galaxy Z Fold 6 and Galaxy Z Flip 6 have received an important certification in China that lists both phones with Samsung's 25W charger. That charger carries the model number EP-TA800 and is the standard 25W charger that is tested by regulatory authorities for every Galaxy smartphone and tablet that supports 25W charging.

However, just because the certification mentions a 25W charger doesn't mean that 25W will be the maximum charging speed on the new phones. Flagship Galaxy phones that support 45W charging are tested with the 25W charger as well, and these certifications aren't always the final confirmation of a device's maximum charging speed.

That said, if Samsung does bring 45W charging to its foldables this year, there's a high likelihood that only the Z Fold 6 will support it. The Z Flip 6 is expected to come with the same battery capacity–4,000 mAh—as the base Galaxy S24, which also tops out at 25W charging (only the S24+ and S24 Ultra can charge at 45W).

It's also worth mentioning that there is no solid evidence that the Z Fold 6 will come with a bigger battery. If it doesn't, then Samsung may not equip either model with 45W support. Samsung is welcome to surprise us, though, especially since its foldables have been stuck at 25W charging since their inception.

More information about the Galaxy Z Fold 6 and Z Flip 6 should begin showing up in the coming weeks as we get closer to the second half of the year. Their official launch will take place in early July, a week or two earlier than the Z Fold 5 and Flip 5.
