Samsung Galaxy Z Fold8 and the ‘wide Fold’ will both have bigger batteries than the Fold7 | Infinium-tech

The Samsung Galaxy Fold line has had the exact same 4,400 mAh battery capacity since the Galaxy Z Fold3, which came out in 2021 — and, funnily enough, 2020’s Fold2 actually had a larger 4,500 mAh battery.

This situation is ridiculous when you look at what Chinese foldables can offer in terms of battery capacity these days, and apparently Samsung is finally going to do something about it. A new rumor claims that the Galaxy Z Fold8, due to launch later this year, will finally increase this battery capacity – but not by much.

However, it will go up to 5,000 mAh, matching the capacity of the Galaxy S26 Ultra, which in itself is not at all impressive in 2026, but Samsung has been stuck here for a while now. So while the Fold8 still won’t match its Chinese competitors in battery size, it will have at least a 14% improvement in capacity compared to every previous Fold since the Fold3.

Today’s rumor claims that the Fold8’s two batteries (one on each side) will have a rated capacity of 2,369 mAh and 2,485 mAh respectively, making a total of 4,854 mAh. This rated capacity will be advertised as a typical capacity of 5,000 mAh.

The ‘Wide Fold’ is also rumored to be launched this year to rival Apple’s iPhone Fold with a similar form factor, with a 4,900 mAh battery instead. Both it and the Fold8 are likely to go official around July.
