Samsung may use an old, disastrous battery supplier for its foldable phones

Notably, back in 2017, Samsung and ATL came together for the Galaxy Note 7, which was a huge disaster for Samsung because of mass reports of the device catching fire. Samsung blamed the batteries produced by ATL as being the cause of the debacle at that time. However, ATL has resumed supplying batteries for the Samsung Galaxy A and M series phones.

In fact, the Samsung Galaxy S21 also sports a battery produced by the Chinese firm ATL. Samsung has used batteries from SDI for foldables like the Galaxy Z Fold and Z Flip. But now the latest reports show that the company might go with ATL for its foldables as well as for cost-cutting measures.

Unfortunately, there is no word on whether or not the Galaxy Z Fold 4 and Galaxy Z Flip 3 will bring battery capacity upgrades, whichever supplier Samsung ends up going with. The Z Fold 4 is said to be a little smaller than the Galaxy Z Fold 3 so the same battery size on both is expected at best, which will leave it up to optimization in the software and to the underlying chipset to provide any endurance gains.
