Best iPhone for Battery Life
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.
| Model | Video playback | Fast charge | Price (new) | Notes |
|---|---|---|---|---|
| iPhone 17 Pro Max | 39 hrs | 40W | $1,199 | Top pick — longest of any iPhone |
| iPhone 17 Pro | 33 hrs | 40W | $999 | Also strong; 6 hrs less than Max |
| iPhone 16 Pro Max | 33 hrs | 45W | $1,199 | 45W is the fastest iPhone charger |
| iPhone 17 | 30 hrs | 40W | $799 | Good all-rounder; 9 hrs more than 16 |
| iPhone 16 Plus | 27 hrs | 25W | $899 | Best value — matches 16 Pro Max |
| iPhone 16 Pro | 27 hrs | 20W | $999 | Same endurance as 16 Plus, $100 more |
| iPhone Air | 27 hrs | 20W | $899 | Thin body; smaller cell per screen size |
| iPhone 14 Plus | 26 hrs | 20W | ~$400 refurb | Budget pick; no longer sold new |
| iPhone 16 | 22 hrs | 20W | $799 | Standard; step down from Plus |
| iPhone 13 mini | 17 hrs | 20W | ~$220 refurb | Avoid for endurance |
| iPhone SE (3rd gen) | 15 hrs | 20W | ~$180 refurb | Worst battery of modern iPhones |
Get more battery life — buy or extend
Refurbished high-endurance models cost 30–50% less, and a MagSafe battery pack extends any model through a long day.
The picks explained
Top pick: iPhone 17 Pro Max — 39 hours
163.4 × 78.0 × 8.75mm · 6.9" OLED · A19 Pro · 40W wired · $1,199
At 39 hours of video playback, the iPhone 17 Pro Max is the clear answer when endurance is non-negotiable. That is 6 more hours than the 17 Pro, and 12 more than the standard 17 — a meaningful gap on a long travel day. The large 163.4 mm frame fits a physically bigger cell, and the A19 Pro chip squeezes more runtime out of each milliwatt-hour than older silicon could.
Fast charging at 40W helps when you do reach an outlet. Apple says 50% in about 35 minutes with a 40W or higher adapter. That is less important on a phone that rarely needs charging mid-day, but it matters if you are starting from a depleted state. See the iPhone charging speeds guide for adapter recommendations.
The $1,199 price is real, and the Pro camera system and titanium build are genuinely useful features — but if you only want battery and don't need triple cameras or ProMotion, the 16 Plus makes more financial sense.
Best value: iPhone 16 Plus — 27 hours
160.9 × 77.8 × 7.8mm · 6.7" OLED · A18 · 25W wired · $899 new / ~$700 refurb
The iPhone 16 Plus delivers exactly the same 27 hours of video playback as the iPhone 16 Pro Max, at $300 less. That is the core of why it earns the best-value label. The 6.7" screen and large chassis house a battery that rivals a Pro for a fraction of the cost, and the A18 chip is fast enough for everything a heavy user will throw at it.
Refurbished units are available from around $700 — roughly 22% under new — and for a phone whose main job is lasting the day, buying certified refurb is a reasonable move. 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 · $799 | iPhone 17 Pro: 33 hrs · $999
The standard iPhone 17 at 30 hours is a significant step up from the 16's 22 hours — the biggest single-generation battery improvement in the standard lineup in years. 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 with the same 40W fast charging as the Pro Max. 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.
Budget pick: iPhone 14 Plus — 26 hours, ~$400 refurb
160.8 × 78.1 × 7.8mm · 6.7" OLED · A15 Bionic · 20W wired
Apple no longer sells the iPhone 14 Plus new, but refurbished units run about $400 — less than half the price of the 17 Pro Max — with 26 hours of video playback. That is within one hour of the 16 Plus, for far less money. The A15 chip keeps it running current iOS without slowdowns, 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 is worth noting separately. Its video playback number (27 hours) looks competitive on paper, but that is achieved despite a 5.64 mm body — the thinnest iPhone ever made. Apple tuned it carefully, but the small physical volume means the battery cell is smaller relative to the screen size than in the Plus or Max. Heavy users pushing the phone with GPS, 5G, and bright screen-on time may find it drains faster than the rating suggests in practice. The Air is not a bad phone; it is just not the right phone when endurance is the primary 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.
Fast charging speeds (40–45W on Pro models, 20–25W on others) do not affect endurance, but they reduce the time you need to top up. A 40W charger can bring a 17 Pro Max from empty to 50% in roughly 35 minutes. If you want the full picture on adapters, see the iPhone charging speeds comparison.
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 genuinely run 16+ hours, this is the most reliable safety net.
Pair a pack with a 30W or faster charger, and you can top up the phone and the pack overnight from a single outlet. The charger itself costs less than $20 and makes a meaningful difference in how quickly you recover from zero. Battery users should treat both as standard kit, not optional extras.

FAQ
Which iPhone has the longest battery life?
The iPhone 17 Pro Max has the longest battery life of any iPhone, with 39 hours of video playback according to Apple. The iPhone 17 Pro and iPhone 16 Pro Max both reach 33 hours, and the iPhone 17 standard model hits 30 hours. These numbers come from Apple's standardized video-playback test, which is the most consistent way to compare models.
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 significantly 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 $899 new or around $700 refurbished. 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 (all models from iPhone 12 through the current 17 lineup, except the SE and 16e). 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.
