Best iPhone for Battery Life
Last updated
Heavy users, travelers, and field workers who spend long days away from outlets need a phone that keeps up. Battery life on iPhones varies more than most people expect — the difference between the worst and best model is more than 24 hours of video playback. Here is how to read those numbers and which models to buy.

Every iPhone ranked by video-playback hours
Apple's video-playback test plays back a full-resolution video on a single charge at typical brightness. It is the most consistent cross-model comparison Apple publishes. See the full iPhone battery comparison for every model going back further.

Get more battery life — buy or extend
Refurbished high-endurance models are worth comparing by condition and warranty, and a MagSafe battery pack can extend any model through a long day.
The picks explained
Top pick: iPhone 18 Pro Max — 45 hours
163.4 × 78.0 × 8.75mm · 6.9" OLED · A20 Pro · 60W-or-higher adapter
At 45 hours of video playback, the iPhone 18 Pro Max is the clear answer if you need the longest runtime. That is 6 more hours than the 17 Pro Max, and 9 more than the 18 Pro. The large 163.4 mm frame fits a physically bigger cell, and the A20 Pro chip is more efficient than the A19 Pro.
Apple specifies up to 50% in around 15 minutes with a 60W-or-higher adapter; maximum device draw is not published. See the iPhone charging speeds guide for adapter language and MagSafe limits.
The Pro camera system and other high-end features are useful, but if you only want battery life and do not need triple cameras or ProMotion, the 16 Plus is the more focused refurbished choice. The previous flagship, the iPhone 17 Pro Max, is rated 39 hours.
iPhone 16 Plus — 27 hours in a large non-Pro body
160.9 × 77.8 × 7.8mm · 6.7" OLED · A18 · 25W MagSafe · new and refurbished listings
The iPhone 16 Plus delivers exactly the same 27 hours of video playback as the iPhone 16 Pro Max. Its 6.7" screen and large chassis make it a practical choice when endurance matters more than a telephoto lens or Pro camera controls.
Refurbished units are worth comparing by condition, battery health, and warranty. The dual-camera system covers most photography needs, though it lacks the telephoto lens of the Pro.
Find a refurbished 16 Plus →Also strong: iPhone 17 and iPhone 17 Pro
iPhone 17: 30 hrs | iPhone 17 Pro: 33 hrs
The standard iPhone 17 is rated for 30 hours, 8 hours more than the 16's 22 hours. If you want a current phone at a moderate price without going to the Max, the 17 makes sense.
The iPhone 17 Pro hits 33 hours and uses the same 40W-or-higher adapter for Apple's fast-charge claim as the Pro Max; maximum device draw is not published. For users who want Pro-tier cameras and don't want the bulk of a Max body, those 6 hours less than the Pro Max is an acceptable trade.
Older refurbished option: iPhone 14 Plus — 26 hours
160.8 × 78.1 × 7.8mm · 6.7" OLED · A15 Bionic · 20W-or-higher adapter
Apple no longer sells the iPhone 14 Plus new, but refurbished units retain a 26-hour video-playback rating. That is within one hour of the 16 Plus. The A15 chip supports current iOS, and it has MagSafe for battery-pack compatibility.
For a field worker or traveler who needs endurance on a tight budget, and isn't chasing the latest camera features, this is the most practical option in the lineup. See what to look for in a refurbished iPhone before buying.
Browse refurbished iPhones →What to avoid if endurance is the goal
Three models stand out as poor choices for battery life. The iPhone SE (3rd gen) scores just 15 hours — the lowest of any current-generation iPhone — because the entire design is built around a small 4.7" chassis with almost no room for a larger cell. The iPhone 13 mini fares only slightly better at 17 hours for the same reason.
The iPhone Air rates 27 hours of video playback on paper, but that comes from a 5.64 mm body — the thinnest iPhone Apple has shipped. The small physical volume means a smaller battery cell relative to the screen than in the Plus or Max. Heavy use with GPS, 5G, and a bright screen may drain it faster than the rating suggests. Skip the Air if endurance is the main criterion.
How to read Apple's battery numbers
Apple publishes three battery metrics: video playback, audio playback, and streaming. Video playback hours are the most useful for comparison because they stress the screen, processor, and wireless radio simultaneously — conditions that mirror real mixed-use. Audio-only numbers look much higher and aren't comparable across models the same way.
Two factors drive battery life: cell capacity and chip efficiency. Bigger bodies (Max, Plus) carry more milliwatt-hours. Newer chips (A19, A18) extract more runtime per milliwatt-hour than older ones. That is why an iPhone 17 Pro Max outlasts a 16 Pro Max by 6 hours despite a similar form factor — better silicon in addition to a larger cell.
Adapter wattage is Apple's fast-charge requirement, not a published maximum device draw, and it does not change rated video-playback hours. See the iPhone charging speeds comparison for MagSafe/Qi limits and adapter language.
Extend any model with a MagSafe battery pack
No matter which model you choose, a MagSafe battery pack adds 10–15 hours of real-world use by snapping magnetically to the back of any iPhone 12 or later. You do not need to plug anything in — it charges while you use the phone. For travel days that run 16+ hours, this is a useful backup.
Pair a pack with a 30W or faster charger, and you can top up the phone and the pack overnight from a single outlet. Compare live accessory listings for compatible chargers and packs. Battery users should treat both as standard kit, not optional extras.

FAQ
Which iPhone has the longest battery life?
The iPhone 18 Pro Max has the longest battery life of any iPhone, with 45 hours of video playback according to Apple. The iPhone Duo is rated 44 hours on the outer screen. The iPhone 17 Pro Max is rated 39 hours.
Why do the Plus and Max models last longer than the standard iPhone?
Bigger bodies hold bigger batteries. The Plus and Max iPhones have taller, thicker chassis that physically fit a larger cell. The chip efficiency matters too, but the primary reason a 17 Pro Max lasts 9 more hours than a 17 Plus is that it carries a larger battery in its 163.4 mm frame.
Is the iPhone 16 Plus a good battery phone?
Yes. The iPhone 16 Plus delivers 27 hours of video playback — the same rating as the iPhone 16 Pro Max — at current new and refurbished listings. It uses a large 6.7-inch chassis without the Pro pricing, making it the best value pick for endurance among current models.
Does a MagSafe battery pack work with all iPhones?
MagSafe battery packs work wirelessly with any iPhone 12 or later that has MagSafe; the iPhone SE is the notable exception. They attach magnetically to the back and charge while you use the phone, adding roughly 10–15 hours of extra use depending on the pack capacity. Older iPhones without MagSafe can still use wired power banks via a Lightning or USB-C cable.
