iPhone 17 vs iPhone 16: What’s Actually New

Apple’s dropped the iPhone 17, and the big question is simple: how much better is it than the iPhone 16? Some changes are genuinely useful; others are just Apple flexing for headlines. I’ve been testing both side by side to see what’s actually new, what’s worth caring about, and what you can safely ignore. Here’s the straight-talking breakdown.

 

1. Design & Display

The iPhone 16 was already a tidy-looking slab of glass and metal, but the 17 smooths a few edges. Bezels are slimmer, the notch has finally been binned off, and the front looks cleaner overall. The big win? ProMotion 120Hz is now standard, so scrolling and swiping feels buttery instead of sticky. Plus, the always-on screen makes it look a bit more alive on your desk.

Is it night and day? Nah. But once you’ve had 120Hz, going back feels like rubbing sandpaper on your eyeballs.

Winner: iPhone 17 – smoother screen, cleaner front, and always-on perks.

 

2. Performance & Power

The 16’s A18 chip was no slouch, but the iPhone 17 packs the new A19 with beefed-up brains for AI and multitasking. Everyday stuff like messages and TikTok feel the same, but fire up a game or edit a chunky 4K video, and you’ll clock the extra oomph.

There’s also a fancy new N1 networking chip, which makes Wi-Fi and Bluetooth more stable. You might not notice until you’re streaming in a packed café and your mate’s phone keeps dropping signal, while yours soldiers on.

Winner: iPhone 17 – not revolutionary for casual use, but future-proof and noticeably faster for heavy lifting.

 

3. Cameras: Snaps & Zooms

Here’s where things get tasty. The 16 gave us a solid 48MP main cam, but the 17 levels up with dual 48MP shooters (main and ultra-wide). Translation: more detail, sharper low-light shots, and fewer potato-looking zooms.

They’ve also chucked in a better front cam (18MP), so your selfies and video calls don’t look like they were taken on a toaster. And with the telephoto baked into the regular model, you don’t need to shell out for a Pro Max just to zoom properly anymore.

Winner: iPhone 17 – sharper cameras all-round, front and back.

 

4. Battery: More Juice, Less Stress

The 16 was decent, lasting most of the day with a bit left in the tank. But the iPhone 17? Absolute champ. We’re talking 30 hours of video playback - easily a full day and then some, even if you’re hammering it with streaming, socials, and sat-nav.

Charging’s quicker too - 50% in around 20 minutes if you’ve got a chunky enough charger. Less time tethered to the wall, more time faffing about online.

Winner: iPhone 17 – longer-lasting and faster-charging.

 

5. The Little Extras

  • Ceramic Shield 2: posher glass that’s less scratch-happy in your pocket.
  • Apple Intelligence: still rolling out, but the 17’s faster chip makes the AI bits run smoother.
  • Emergency SOS via satellite: still here — hopefully you’ll never need it, but it’s comforting if you go hiking or get stranded in the middle of nowhere.

Most of these feel like polishing rather than headline features, but it’s polish that helps the 17 shine a bit brighter.

Winner: iPhone 17 – mostly minor, but useful extras.

So, Worth the Upgrade or Not?

  • On an iPhone 12, 13, or 14? This is a massive glow-up. New screen, cameras, battery - you’ll notice straight away.
  • On a 16? If your battery’s knackered or you do loads of gaming and content creation, the 17 is tempting. Otherwise, your 16’s still got plenty of life left.
  • On a 16 Pro or Pro Max? The jump feels smaller. Unless you’ve got upgrade cash burning a hole in your pocket, you’re safe to wait.

 

 

Final Verdict

The iPhone 17 isn’t a total reinvention - it’s Apple doing what they do best: polishing, tweaking, and nudging things forward just enough to make you think about it. The 120Hz display and battery life are proper standouts, and the camera boost is hard to ignore. But if you’ve only just snagged a 16, don’t feel left behind.

 

 

Before You Decide…

Is the iPhone 17 worth upgrading from the iPhone 16?
If you care about better battery life, smoother 120Hz display, and sharper cameras, the iPhone 17 is a clear step up. But if you’re happy with your 16 and it’s still running well, you’re not missing out on anything revolutionary.

What’s the biggest difference between iPhone 16 and iPhone 17?
The iPhone 17’s standout upgrades are its ProMotion display, improved battery life, and upgraded dual 48MP cameras. These are the changes you’ll actually notice day to day.

Does the iPhone 17 have better battery life than the iPhone 16?
Yes — the iPhone 17 pushes video playback to around 30 hours (vs 22 on the iPhone 16) and charges faster too (50% in about 20 minutes with the right charger).

Are the iPhone 17 cameras better than the iPhone 16?
Definitely. The iPhone 17 has dual 48MP lenses (main + ultra-wide) plus a better telephoto option and upgraded front camera. The iPhone 16 is still solid, but the 17 wins for detail and low-light performance.

Should I upgrade if I already own the iPhone 16 Pro or Pro Max?
Probably not. The improvements are nice but not massive compared to the Pro models. Unless your battery’s worn out or you crave the new features, you can comfortably stick with your 16 Pro.

How much faster is the iPhone 17 compared to the iPhone 16?
In everyday use, you might not feel much difference. But under heavy loads like gaming, video editing, or AI features, the iPhone 17’s A19 chip and N1 networking chip make it smoother and more future-proof.

Apple’s iPhone 17 Pro Max has arrived with some serious promises around battery life. With a larger battery capacity than its predecessor, more efficient internals, and better software optimisation, Apple claims this could be its longest-lasting iPhone yet.

Official Specs & Improvements

  • Battery Capacity: The iPhone 17 Pro Max comes with a 5,088 mAh battery in its eSIM-only version, and about 4,823 mAh in variants with a physical SIM tray. That’s up from the ~4,685 mAh in the iPhone 16 Pro Max.

iPhone 17 Accessories You Need: Best MagSafe Chargers, Cases & More

Apple’s iPhone 17 lineup brings its usual mix of refinements: better materials, updated finishes, perhaps new colours, magnets for MagSafe, and improved wireless charging. To get the most from your device — protection, fast charging, functionality — you’ll want to pair it with the right accessories. Here’s a deep guide to the best ones: what to buy, what to watch out for, and what’s new as of late 2025 in the UK.

 

What’s New / What’s Changed

Before diving into accessories, a few pieces of context so you understand what the latest gear supports and why some older accessories may or may not do as well:

  • The iPhone 17 series is confirmed to support MagSafe accessories fully. Cases, chargers, wallets, etc., are all designed around MagSafe compatibility.
  • Wireless charging standards are improving: Apple has updated its MagSafe charger to support up to 25 W charging under the newer Qi2.2 standard. This improves over the earlier generation’s speeds.
  • Apple is also pushing new designs and materials

New iPhone 17 Design: Horizontal Camera Bar & Bold Colours Revealed

Apple’s iPhone 17 has officially arrived, and while performance upgrades and Apple Intelligence integration are making headlines, the iPhone 17 design is where the biggest visual leap has taken place. From bold new colours to precision-engineered materials, Apple has created a handset that’s as much a style statement as it is a powerful everyday tool.

 

A Fresh Finish: Colours That Pop

For the UK market, Apple has given the iPhone 17 an expressive new palette:

  • Black
  • White
  • Mist Blue
  • Sage
  • Lavender

Unlike previous generations where colours were more muted, the iPhone 17 introduces a colour-infused glass back for Black, Mist Blue, Sage, and Lavender. This technique allows Apple to achieve vibrant, durable tones that won’t easily fade or scratch away. The White finish, on the other hand, retains a classic gloss look for those who prefer understated elegance.

This combination of bold and timeless choices ensures there’s something for everyone — whether you want your iPhone to stand out or blend
