The S25 Ultra vs iPhone 17 Pro battery comparison is one of the most debated topics among smartphone enthusiasts. While the Samsung Galaxy S25 Ultra boasts a 5,000mAh battery, the iPhone 17 Pro features a 4,252mAh battery combined with software optimization for efficient performance. In this article, we’ll explore battery capacities, real-world usage, and performance differences to see which device truly offers better endurance.
Battery Capacity Comparison: S25 Ultra vs iPhone 17 Pro
The iPhone 17 is already entitled to comparisons with the Samsung Galaxy S25, while the former have not even been delivered by Apple yet! The Android press affirm that The Ultra Galaxy S25 has a more durable battery than all iPhone 17s Reunited. However, there are certain shades to take into account.
The Samsung battery would be 2x more sustainable
The comparison takes as reference the new compulsory label that all manufacturers must display when selling a smartphone in Europe, like energy labeling for household appliances. Smartphone labels aim to help you make a more informed choice during a new purchase.
As with a fridge or a washing machine, the smartphone is noted here on several objective criteria: its energy consumption, battery life, the solidity of the device and its reparability. The label also indicates the standard of sealing it respects, as well as The number of load cycles that the battery can perform before starting to deteriorate.
As you can see, the four new iPhones have, according to the label, a battery that would start to deteriorate after 1000 cycles. The Samsung Galaxy S25 would be able to bear double, 2000 cycles.
Does this figure really reflect reality?
Apple recently said, in an official 44-page document, that it voluntarily underestimated certain energy scores in the European Union. This includes the number of battery load cycles before decline. Explanations here.
