iPhone 17 Pro Max vs Galaxy S26 Ultra: A Battle of Battery Capacities

Source: Date:
iPhone 17 Pro Max is rumored to be equipped with a larger battery compared to its predecessor, while the Galaxy S26 Ultra is said to stick with the same battery capacity as the previous model. This decision has sparked debates among tech enthusiasts, with some questioning whether Samsung made the right choice. iPhone 15 Pro and iPhone 16 Pro feature titanium frames, but the upcoming iPhone may see a shift to aluminum for a lighter build. The iPhone 17 Pro Max is expected to come with a 4,823mAh battery, with the eSIM model possibly offering a 5,088mAh cell, resulting in a thicker design at 8.725mm. On the other hand, the Galaxy S26 Ultra is likely to maintain its 5,000mAh battery capacity while getting slimmer at 7.9mm thickness.

seventh Ultra handset in a row to have a 5,000mAh battery. This is bound to infuriate Ultra fans, but the same battery capacity doesn't necessarily mean the Galaxy S26 Ultra will have the same battery life as the Galaxy S25 Ultra. It may rely on other measures, such as the use of more power-efficient components, to make the phone last longer on a single charge. The Galaxy S26 Ultra is also likely to support faster charging, which might somewhat make up for the unchanged battery capacity.
