- Samsung says it didn’t give Z Fold 7 a larger battery because users would have it to prioritize other features
- Instead, the business prioritized to improve the cameras, make the phone thinner and give it a wider coverage screen
- But with silicon-carbon battery technology that is now available, it seems that the company could still have upgraded the battery too
The Samsung Galaxy Z Fold 7 is an upgrade in the previous model in several ways, but a remarkable area where Samsung has not made any improvements is the battery capacity where both phones have a 4,400mAh device.
This is especially weird as the battery capacity was one of the most important things that the company improved on the Samsung Galaxy Z Flip 7 – and now Samsung has explained its reasoning.
In a speech with Sammobile, the company has claimed that in the case of the Samsung Galaxy Z Flip 7, a larger battery was the most sought -after feature of users, but with the Galaxy Z Fold 7, there were other priorities from folding fans, including “better cameras, a thinner and lighter body and a wider coverage screen.”
But we are not entirely convinced of this explanation for a few reasons. First, 4,400mAh is really a very low capacity for a phone of this size with the much smaller Samsung Galaxy S25 Ultra, for example, to have a much larger 5,000 mAh battery.
So the Galaxy Z Fold 7 could certainly have done with a larger battery, and with the phone that was now longer and wider (thanks to its larger screens), Samsung could certainly have found space for a larger battery if it had not chosen to slim slim phone instead.
The best of both worlds
But Samsung didn’t even necessarily have to choose between a thinner phone and a larger battery. That’s because some handset-inclusive OnePlus 13 and the folding Honor Magic V5-NOW use silicon-carbon batteries.
This type of battery technology allows you to increase the battery capacity without increasing its size, and it is a technology that Samsung allegedly considered using for the Galaxy S26 series -a line of phones that are undoubtedly smaller that needs this as the Samsung Galaxy S25 series already has decent battery capacity for their screen size.
So why couldn’t Samsung offer this technique in the Galaxy Z Fold 7? It is perhaps a matter of cost, with a silicon-carbon battery that may be pushing the price up. Or maybe Samsung exhibits an abundance of caution in rising capacity so as not to risk a repeat of the widespread battery problems facing Samsung Galaxy Note 7.
The good news is at least that if Samsung is really considering silicon-carbon batteries for the Galaxy S25 line, the same technique can be used for the Samsung Galaxy Z Fold 8-It is just a shame that we will have to wait another year to possibly get it.
