Is the iPhone 18 Pro Worth the Upgrade? Battery Life, Charging & More

For most iPhone 17 Pro owners, the honest answer is no.

The iPhone 18 Pro is a refinement of last year’s phone rather than a leap in technology: a faster chip, better cooling, a sharper camera and modestly better battery, with the same 25 W wireless charging.

If you’re coming from an iPhone 16 Pro or older, the case is much stronger.

And if your main frustration is slow charging, a compatible faster charger may improve your experience for much less than a new phone. If battery life is the problem, however, a new charger will not increase how long the phone lasts on a single charge. This guide weighs what the early reviews found against Apple’s own figures, so you can place yourself on the right side of the decision.

Quick takeaways

• The iPhone 18 Pro is a refinement of the 17 Pro: a faster A20 Pro chip, better thermals and an improved camera.
• Battery life improves modestly: Apple rates the UK iPhone 18 Pro at up to 34 hours of video playback versus 31 hours for the iPhone 17 Pro, while one independent browsing test found an improvement of around 6%.
• Charging is the clearer upgrade: Apple quotes around 50% in 15 minutes with a compatible 60 W-capable AVS adapter and suitable USB-C cable, versus around 20 minutes on the iPhone 17 Pro under Apple’s stated test conditions.
• It weighs 211 g, 7 g more than the 17 Pro, and launched £100 dearer.
• Reviewer consensus: iPhone 17 Pro owners can skip it, while iPhone 16 Pro and older users have a real reason to upgrade.

Is the iPhone 18 Pro worth upgrading from the iPhone 17 Pro?

Introducing the new iPhone 18 Pro

For most people using iPhone 17 Pro, no. Reviewers broadly call the iPhone 18 Pro a refinement rather than a reinvention: a faster chip, better cooling and a better camera, but a battery that’s only a little improved and the same 25 W wireless charging.

If you own a 17 Pro, the gains rarely justify the cost. If you own a 16 Pro or older, the cumulative jump is far more worthwhile.

Most of the people who reviewed it at length land in the same place.

9to5Mac describes the 18 Pro as more of the same, a polish of the 17 Pro, and says 17 Pro owners have little reason to move while 16 Pro and older owners have a great time to.

TechAdvisor reaches a similar verdict in its iPhone 18 Pro review, calling the improvements largely incremental and suggesting 2026 is not the year to invest in a new flagship unless money is no object, with a redesign expected in 2027.

The decision, then, hinges almost entirely on what you’re upgrading from. Before budgeting for extras, it helps to know which charging accessories are worth buying for the iPhone 18 Pro.

iPhone 18 Pro battery life: how much better is it?

Modestly better, not transformed. Apple rates the UK iPhone 18 Pro at up to 34 hours of video playback versus 31 hours for the iPhone 17 Pro, while a TechRadar browsing test cited by BGR found an improvement of around 6%.

That may be noticeable over a long day, but it is not a step change. Both phones can last a full day under many typical usage patterns, so battery life alone may not justify upgrading if your current iPhone already meets your needs.

Apple’s own figures set the scale: 34 hours of video playback on the 18 Pro, up from 31 hours on the 17 Pro, with typical-use ratings of 23 hours on the Pro and 29 on the Pro Max.

The real-world testing lines up with a small gain rather than a big one. BGR gathered the independent results, and its comparison cites a TechRadar browsing test in which the 18 Pro ran for 16.17 hours against the 17 Pro’s 15.21, about 6% more, with a Pro Max result around 3%.

The takeaway is a genuine but minor improvement. If you expected the 18 Pro to double your screen time, it won’t. If your current phone mainly runs short of power on longer days, magnetic wireless power banks can provide portable backup power without replacing the handset.

iPhone 18 Pro charging speed: the real improvement

Charging is where the 18 Pro clearly pulls ahead. Apple quotes 50% in around 15 minutes with a compatible 60 W-capable AVS adapter and suitable USB-C cable, against about 20 minutes on the 17 Pro under Apple’s test conditions. TechAdvisor measured 44% in 15 minutes and 77% in 30 minutes on a fast charger. Wireless charging stays at 25 W with MagSafe and Qi2. The catch: Apple still includes only a cable in the box, not a plug.

This is an upgrade you may notice if you regularly rely on quick wired top-ups.

Apple’s stated half-charge time improves from around 20 minutes on the iPhone 17 Pro to around 15 minutes on the iPhone 18 Pro under their respective test conditions. In TechAdvisor’s independent test, the iPhone 18 Pro reached 44% in 15 minutes, showing that actual results can differ from Apple’s advertised figure. To compare charging methods, see how MagSafe charging compares with wired USB-C charging on iPhone 18 Pro.

The fastest advertised wired charging result requires a compatible 60 W-capable adapter supporting Adjustable Voltage Supply (AVS), a mode within USB Power Delivery.

To achieve Apple’s stated 15-minute fast-charging result, the iPhone 18 Pro requires a compatible USB-C PD adapter with 60 W-capable output and AVS support, together with a suitable USB-C cable. You can compare USB-C to USB-C charging cables by their supported power ratings.

When choosing from UGREEN’s Nexode range, check the individual model’s specifications to confirm that it supports the required charging profile. For general selection criteria, see how to choose a wall charger by power, ports, size and safety.

What else is new on the iPhone 18 Pro?

iPhone 18 Pro Review: All About that Chip

The true upgrades are the A20 Pro chip and the camera. In 9to5Mac’s testing, the A20 Pro CPU performed around 22–27% faster than the A19 Pro, while GPU results were around 40–45% higher. A larger vapour chamber also improves thermal management and sustained performance over the iPhone 17 Pro.

The camera gains a mechanical variable aperture and stronger low-light shots. Against those wins, the phone is 7 g heavier than the 17 Pro and is priced at £100 more.

For users who rely on heavy workloads, these gains may be noticeable. 9to5Mac found the A20 Pro 22–27% quicker on the CPU and 40–45% on the GPU, and reported improved thermal performance from its enlarged vapour chamber.

For photography, TechAdvisor rated the new variable-aperture 48 MP main sensor and its low-light results highly, and valued the telephoto reach.

These are upgrades a photographer or a power user will use every day. A messaging-and-browsing user will notice the weight and the price more than the chip. It’s the clearest line between who should upgrade and who shouldn’t.

Should you upgrade, or keep your iPhone and improve your charging?

Upgrade if you’re on an iPhone 16 Pro or older, or if you’re a photographer or power user who’ll lean on the camera and chip daily.

Keep your current iPhone if you’re on a 17 Pro and happy with it. If your main frustration is slow charging, a compatible USB-C or MagSafe charger may offer a more affordable improvement than replacing your phone. If your battery no longer lasts long enough, check its health and your daily usage before deciding whether you need a battery replacement, portable backup power or a new iPhone.

That last point is the one most upgrade guides skip. If you need a replacement adapter, compare USB-C wall chargers against the charging requirements of your existing phone.

Charging-speed complaints may come from an unsuitable adapter or cable. Poor battery life is a different issue and may be related to battery health, background activity or how the phone is used.

A compatible faster adapter can cut the time your phone spends tethered to the wall, while wireless charging makes topping up convenient at a desk or bedside on an iPhone you already own. If you are choosing a wireless setup, consider which MagSafe charger design best suits your desk or bedside.

A compatible Qi2 25 W charger from UGREEN’s MagFlow range delivers up to 25 W wireless charging to supported iPhone models, including the iPhone 18 Pro. Actual charging power depends on the iPhone model, charger compatibility and charging conditions.

Before spending over £1,000 on a new iPhone, check whether a suitable charger could solve your specific charging-speed problem. If your concern is battery life rather than charging speed, assess that separately.

The short version

The iPhone 18 Pro is a good phone, but a small upgrade. Its battery is only a little better than the 17 Pro’s. The real improvement is faster charging, and the chip and camera are the gains that justify the price for photographers and power users.

If you’re on a 17 Pro, keep it. If you’re on a 16 Pro or older, it’s a worthwhile jump.

If charging speed is your main frustration, check whether your current charger meets your iPhone’s supported charging requirements before replacing the phone. If battery life is the issue, assess your battery health and daily usage separately.
