Which iPhone Has The Best Battery Life?
If you want the best possible battery life from your next iPhone, you’ll want to go with either the Plus or the Pro Max model. Currently, that’d be the iPhone 15 Plus or the iPhone 15 Pro Max.
These models have a larger display and an overall bigger chassis, so, by proxy, they run a larger battery. Apple’s current level of power management with its hardware and A-series chipsets is brilliant, so even with the smaller (6.1in) models, you’ll still get all day battery life.
The only weak links in Apple’s iPhone with respect to battery were the iPhone 12 series, following Apple’s botched adoption of 5G, and the ill-fated iPhone Mini models which were just too small to pack in a decent-sized battery.
From the iPhone 13 series onwards, excluding the iPhone 13 mini, battery life is no longer an issue on iPhone. You’ll get through an entire day with moderate to heavy usage, even on the base models.
I know this because I currently run the iPhone 13 and have tested both the iPhone 15 and iPhone 14 models. The only reason I didn’t upgrade was because my iPhone 13 still runs fine, so why waste the cash?
