- Samsung says that he did not give the Z Fold 7 a bigger battery because the users wanted him to prioritize the other features
- Instead, the company has prioritized the improvement of cameras, making the phone thinner and giving it a wider cover screen
- However, with silicon-carbon battery technology now available, it seems that the company could still have improved the battery
The Samsung Galaxy Z Fold 7 is an upgrade of the previous model with many ways, but a notable area where Samsung has not made any improvement is the battery capacity, the two phones with a unit of 4400 mAh.
This is particularly strange because the battery capacity was one of the main things that the company has improved on the Samsung Galaxy Z Flip 7 – and now Samsung has explained its reasoning.
Addressing Sambile, the company said that in the case of the Samsung Galaxy Z Flip 7, a larger battery was the most sought after by users, but with the Galaxy Z Fold 7, there were other foldable fans priorities, including “better cameras, a slim and lighter body, and a wider cover screen”.
But we are not entirely convinced by this explanation for several reasons. First of all, 4,400mAh is really a very low capacity for a phone of this size, with the Samsung Galaxy S25 S25, much smaller, having a much larger 5,000 mAh battery.
Thus, the Galaxy Z Fold 7 could certainly have done with a larger battery, and with the phone now being longer and wider (thanks to its larger screens), Samsung could surely have found space for a larger battery if it had not chosen to refuse the phone more instead.
The best of both worlds
But Samsung didn’t even necessarily need to choose between a thinner phone and a larger battery. This is because some handsets – including the OnePlus 13 and the Foldable Honor Magic V5 – now use carbon silicon carbon batteries.
This type of battery technology allows you to increase battery capacity without increasing its size, and this is a technology that Samsung will plan to use for the Galaxy S26 series – a range of phones that are undoubtedly less necessary, because the Samsung Galaxy S25 series already has decent battery capacities for their screen size.
So why could Samsung not offer this technology in the Galaxy Z Fold 7? It may be a question of cost, with a carbon silicon battery that may push the price. Or maybe Samsung shows an abundance of prudence in increasing capacities, so as not to risk a repetition of the widespread battery problems faced by the Samsung Galaxy Note 7.
The good news is at least that if Samsung really envisages silicon-carbon batteries for the Galaxy S25 line, the same technology may well be used for the Samsung Galaxy Z Fold 8-it’s just a shame that we should wait another year to maybe get it.
