In terms of battery life, the iPhone 18 Pro and the iPhone 17 Pro appear to be a significant improvement on the paper. For video playback, Apple claims the 18 Pro can enjoy 36 hours versus 33 hours for the 17 Pro, and charging will happen quicker with a 60W-capable adapter (50% in 15 minutes versus 20 minutes). The truth is that nothing changed in the physical battery, except a bit more. The teardown revealed the North American iPhone 18 Pro is equipped with a 4,288mAh battery, which is approximately 1% larger than the 4,252mAh battery that was used in the previous iPhone.This means that that the benefits are going to be largely from the more efficient A20 Pro chip and software optimization. It's been backed up by independent tests showing small but real improvements. Tom's Guide found that the 18 Pro will allow you to browse the web for about 16 hours 17 minutes, compared to the 17 Pro at 15 hours 17 minutes, which is about an hour longer. The same was true of the 18 Pro when playing Genshin Impact, which lasted nearly an hour longer than the 17 Pro in Dave2D's loop test.

It will be most apparent to casual users due to the faster charging on top. Apple states that the battery life of the 18 Pro is the same as that of the 17 Pro Max, but PhoneArena's streaming test revealed that it's a little behind the Max.Battery is not a compelling reason to upgrade the 17 Pro.
