iPhone 18 Pro vs iPhone 16 Pro: Worth Upgrading?
A 20% bigger battery, 60W charging and a variable aperture camera — for $200 more. Whether that is worth it depends on one thing, and it is not the chip.
The Quick Verdict
Choosing between the Apple iPhone 18 Pro and the Apple iPhone 16 Pro comes down to your personal priorities:
iPhone 16 Pro owners whose battery no longer lasts the day, and anyone who shoots in poor light
Owners whose battery still holds up, and buyers who want a capable Pro iPhone for well under $1,199

The Quick Verdict
Upgrade if your iPhone 16 Pro battery no longer lasts the day. Otherwise, don't.
That is not a hedge. It is the actual shape of this upgrade: the battery and charging changes are large and useful, the camera change is genuinely new, and the chip change is real but the least likely to affect you.

Battery: The Reason to Upgrade
PhoneArena puts the iPhone 18 Pro at 4,056 mAh (4,288 mAh on eSIM-only models) against the iPhone 16 Pro's 3,582 mAh — close to 20% more. Apple calls it the largest increase in battery life in the iPhone's history.
For context on what that delivers, Tom's Guide measured the iPhone 18 Pro at 16:17 average on its 5G web-browsing test at 150 nits, against 15:21 for the iPhone 17 Pro.
Here is why this matters more than the specification suggests. A two-year-old iPhone 16 Pro does not have a 3,582 mAh battery any more — it has whatever degradation has left it with. So the practical gap for an existing owner is larger than 20%.
Check Settings → Battery → Battery Health before you decide anything else on this page. If it is above 85%, most of this upgrade's value does not apply to you.

Charging
The 18 Pro charges at 60W, reaching 50% in about 15 minutes. The 16 Pro tops out around 25W, taking roughly 30 minutes for the same.
In daily use this may be the more noticeable of the two battery-related changes. A fifteen-minute top-up before leaving the house is a different behaviour from a thirty-minute one.
---
The Camera Actually Changed
This is the part that is genuinely new rather than incrementally better.
Apple says the 48MP Fusion Main camera uses six laser-cut blades to move between f/1.48 and f/4. Wide open, it gathers more light in dim scenes. Stopped down, it keeps more of a group in focus.
Phone cameras have faked depth of field in software for years. This is mechanical optics doing it properly, and it is unusual on a phone.
MacRumors counts more than fifty differences between the 2024 and 2026 Pro models. This is the one worth caring about.
---
The Chip, and Why It Matters Least
Tom's Guide recorded Geekbench 6 scores of 4,719 single-core and 12,677 multi-core for the A20 Pro, built on 2nm.
That is a large lead over the A18 Pro in the 16 Pro. It is also, for almost everyone reading this, irrelevant. Both phones run every app in the store without hesitation. The gap appears in sustained work — exporting video, processing large photo batches — and in how current the phone still feels in year four.
Do not upgrade for the chip.

The $200 Question
The iPhone 18 Pro starts at $1,199 for 256GB. The iPhone 16 Pro launched at $999 for 128GB, per Business Today.
So it is $200 more — but the base storage doubled, which takes some of the sting out. If you were going to buy the 256GB tier anyway, the real-world gap is smaller than the headline.
Worth knowing before you commit: the pattern across the industry is that this year's flagship costs about 30% less in six months. Our iPhone 18 Pro Max vs Galaxy S26 Ultra comparison shows exactly that — the Samsung is now around $915 against a $1,299 launch. If you can wait, waiting pays.

Pros & Cons Consensus
Apple iPhone 18 Pro
- 4,056 mAh battery (4,288 mAh on eSIM models) against the 16 Pro's 3,582 mAh — close to 20% more
- 60W charging reaches 50% in about 15 minutes, against roughly 25W and 30 minutes on the 16 Pro
- Mechanical variable aperture from f/1.48 to f/4 using six laser-cut blades (Apple)
- A20 Pro on 2nm: Geekbench 6 of 4,719 single-core and 12,677 multi-core (Tom's Guide)
- Base storage doubled to 256GB, and a smaller Dynamic Island
- $1,199 against the 16 Pro's $999 launch price — a $200 increase
- The chip gain is the least useful part of the upgrade for most people
- Still no periscope zoom, so Android rivals out-reach it
- If your 16 Pro battery is healthy, the headline improvement does not apply to you
Apple iPhone 16 Pro
- Still a capable phone: nothing on the App Store asks more than it can give
- Considerably cheaper now on the used and refurbished market
- Camera Control button and the Pro camera system
- Holding onto it for another year costs nothing
- 3,582 mAh battery, roughly 20% smaller than the 18 Pro's
- Charging tops up 50% in about 30 minutes rather than 15
- No variable aperture, so low light is a step behind
- 128GB entry tier now looks thin against 256GB
It depends on your battery
Upgrade if your 16 Pro no longer lasts the day. Otherwise wait.
Skipping a generation makes this a real upgrade rather than a marginal one — MacRumors counts more than fifty differences between the 2024 and 2026 Pro models. But they are not equally useful. The battery goes from 3,582 mAh to 4,056 mAh, close to 20% more, and charging goes from roughly 25W to 60W, halving the time to 50%. The camera gains a genuine mechanical aperture that moves between f/1.48 and f/4. The A20 Pro is much faster, and that is the part you are least likely to notice. So the honest test is simple: if your iPhone 16 Pro is two years old and no longer reaches the evening, the $200 premium buys you exactly the thing that is bothering you. If your battery is still healthy and you are happy with your photos, there is nothing here you need. Waiting another year costs you nothing.
Choose Apple iPhone 18 Pro If:
- Your iPhone 16 Pro battery no longer lasts a full day
- You shoot in low light often enough to care about f/1.48
- You are tired of 30-minute top-ups
- You were running out of space on 128GB
Choose Apple iPhone 16 Pro If:
- Your battery health is still good
- You mostly shoot in daylight
- $200 is better spent elsewhere
- You would rather buy a discounted 16 Pro than a new 18 Pro
Frequently Asked Questions
Should I upgrade from an iPhone 16 Pro to an iPhone 18 Pro?
Only if your battery has stopped lasting the day. That is the upgrade's real content: the 18 Pro carries 4,056 mAh against the 16 Pro's 3,582 mAh, close to 20% more, and charges at 60W rather than about 25W. If your battery health is still good, nothing else here is urgent enough to justify $1,199.
How much bigger is the iPhone 18 Pro battery?
Nearly 20%. PhoneArena reports 4,056 mAh in the global model and 4,288 mAh in the eSIM version, against 3,582 mAh in the iPhone 16 Pro. Apple describes it as the largest increase in battery life in the iPhone's history.
How fast does the iPhone 18 Pro charge?
60W wired, reaching 50% in about 15 minutes. The iPhone 16 Pro tops out around 25W and takes roughly 30 minutes to reach the same point. In daily use this is arguably more noticeable than the larger battery.
What does the variable aperture do?
Apple says six laser-cut blades move the 48MP main camera between f/1.48 and f/4. Wide open it gathers more light for dim scenes; stopped down it keeps more of a group in focus. It is real mechanical optics rather than a software effect, and it is the most genuinely new thing on the phone.
Is the iPhone 18 Pro much faster than the 16 Pro?
Yes — Tom's Guide measured Geekbench 6 scores of 4,719 and 12,677 for the A20 Pro, well ahead of the A18 Pro. It is also the difference you are least likely to feel. Both phones run everything on the App Store without complaint; the gap shows up in sustained work like video export.
Is the iPhone 16 Pro still worth buying in 2026?
On the used and refurbished market, yes. It remains a capable Pro iPhone and nothing in the App Store strains it. What you give up is battery capacity, charging speed and the variable aperture — and you save considerably more than the $200 difference in launch prices.
