According to the latest leaks, the Galaxy Z Fold8 (formerly known as Galaxy Z Fold Wide) and the Galaxy Z Fold8 Ultra (a direct successor to the Galaxy Z Fold7) are expected to come with considerably larger batteries compared to their older siblings. Some rumors suggest Samsung is finally adopting the Si/C battery technology.

The European Product Registry for Energy Labeling (EPREL) published the endurance rating of the Galaxy Z Fold8 and the Galaxy Z Fold8 Ultra — 49:10h and 51:00h, respectively. The two handsets achieve the scores using 4,800 mAh and 5,000 mAh batteries.

Now, if you compare the Galaxy Z Fold8 Ultra and the Galaxy Z Fold7 predecessor with a 40:28h rating and a 4,400 mAh battery, the endurance improvement is roughly 20%. Of course, your experience may vary as everyone uses their phones differently.

One thing is for certain at this point — the new Galaxy Z Fold8 lineup will offer larger batteries, a much-needed upgrade.
