The latest piece of information about the Galaxy Z Flip 4’s battery capacity contradicts previous information though. The device was said to include two battery units with rated capacities of 2,400mAh and 903mAh for a total of 3,303mAh, which could mean a typical capacity of 3,400mAh. But Samsung may have somehow created extra space inside the clamshell foldable for additional battery juice. The Korean media recently reported that Samsung is looking to introduce stacked-type smartphone batteries soon. Currently used for electric vehicle (EV) batteries, this technology allows for a higher battery capacity in a smaller package thanks to tighter packaging of components. Reports claim as much as ten percent extra battery juice in a similar-sized unit. Maybe Samsung is using this packaging technology for a bigger battery inside the Galaxy Z Fold 4 while keeping the same size. Even the reported 3,700mAh battery unit is in line with that. We will likely find it out in the coming months.

The Galaxy Z Fold 4 will not get any notable battery upgrade

While the Galaxy Z Flip 4 is getting some much-needed upgrades both in terms of battery capacity and charging speed, Samsung isn’t treating its other 2022 foldable model likewise. The Galaxy Z Fold 4 was previously rumored to include a combined battery capacity of 4,400mAh, which is unchanged from the Fold 3 last year. Perhaps a Safety Korea certification had revealed that. Ice Universe is now corroborating that information with “100 percent” accuracy. This model is undergoing a shape change this year. The device will come squarer than its predecessor. It’s unclear whether this redesign has eaten up a little extra space inside the device or if there’s some other reason for it keeping the same battery capacity. A 4,400mAh battery is not too bad though. Just that a bigger battery would have ensured longer endurance, which everyone would love. Nonetheless, the Galaxy Z Fold 4 and Galaxy Z Flip 4 aren’t expected to arrive before August this year. Among other things, the devices could get camera and display upgrades. We expect to hear a lot more about the new foldables until then. Stay tuned.
