• We've put the batteries in Apple's newest iPhones to the test
• There are upgrades here, but not huge ones
• Apple has been touting major boosts in battery life on these handsets

Sift through the press releases that Apple pushed out while announcing the new iPhone 18 Pro and iPhone 18 Pro Max, and you'll see some big battery life increases touted — including "the largest increase in battery life ever" on an iPhone with the Pro Max model (compared to the iPhone 17 Pro Max).

We know that the iPhone 18 Pro and iPhone 18 Pro Max come with 4,056 mAh and 5,391 mAh capacity batteries respectively (at least in Europe), but does that translate into much better battery life? We put both of these new handsets through their paces in the TechRadar labs (as part of our full iPhone 18 Pro review) to see if Apple's claims held up under some real-world testing.

Our standard test involves having the iPhone automatically cycle through a series of websites over a cellular connection, until the battery dies. Features like location services, Wi-Fi, and Bluetooth are all turned off while the test is being run, and the battery management features in iOS are disabled too.

The iPhone 18 Pro managed 16 hours and 17 minutes in the test, compared to 15 hours and 21 minutes on the iPhone 17 Pro, a boost of around 6% overall. The iPhone 18 Pro Max managed 18 hours and 27 minutes compared to 17 hours and 54 minutes on the iPhone 17 Pro Max, an increase of roughly 3% in total.

Those increases are of course welcome, but perhaps aren't quite as impressive as Apple is making out, though there are a lot of different variables (like screen brightness) involved. Apple's own figures usually make use of video playback time — as in how long a single battery charge lasts when you've watching a video.

For the iPhone 17 Pro and iPhone 17 Pro Max, Apple quotes 33 hours and 39 hours respectively, while for the iPhone 18 Pro and iPhone 18 Pro Max those numbers go up to 36 hours (a 9% increase) and 45 hours (a 15% increase). That last jump is indeed significant, but may only apply in quite a narrow set of scenarios.

"All battery claims depend on network configuration and many other factors," explains Apple in the small print on its comparison page. "Actual results will vary. Batteries have limited recharge cycles and may eventually need to be replaced. Battery life and charge cycles vary by use and settings."

We can safely say that you should see better battery life on the iPhone 18 Pro and Pro Max compared to the models that preceded them, but based on our own testing, don't expect the kind of improvements Apple is promising unless you're doing nothing but watching videos in long stretches between recharges.

• New camera-free smart glasses from Meta are rumored
• The wearable could be unveiled as early as next week
• A new glasses-detecting app is proving popular with users

It's fair to say that the various iterations of Meta's smart glasses had been quite well received by users — as you'll see from our own reviews — but over time, the general public has become less and less comfortable with the idea of being secretly spied on through the cameras embedded in these wearables.

That might explain Meta's plans to release some spectacles with cameras on board, as reported by The Information. According to the outlet's sources, the glasses have the codename Luna, and will be available in two styles called Clubmaster and Burbank.

With no camera, the focus will be on the audio capabilities of the glasses, which will let you have conversations with Meta's own AI chatbot. The report says we could get a grand unveiling at the Meta Connect event next week, on September 23 and 24.

While Meta's smart specs have always been fitted with LED lights that show when they're recording, modders were finding ways around this, enabling more covert video and photo capture. While those mods have since been disabled and prevented by software updates, it's still left people with a general sense of unease.

The backlash continues

As Meta apparently preps its next pair of smart glasses, Wired reports on the ZuckOff app that takes a swing at the Meta CEO in its name, and alerts users when they might be in the presence of someone wearing Meta glasses. The app uses Bluetooth to scan the surrounding area for these wearables.

With several thousand downloads on both Android and iOS, the app is clearly proving popular. It's free to download and use in its basic form, with a pro version available for $9.99 / £9.99 / AU$14.99 a year that scans continuously and gives you scan histories.

It's not your only option either: if you're on Android, Nearby Glasses is open source and free to use, and does a similar sort of job as ZuckOff without the provocative name. That app has now racked up more than 100,000 downloads.

There's definitely been a shift in perception when it comes to glasses that can record, warning light or no warning light — even though these specs have been around for years. There's even talk of bans and government regulation coming in at some point, which Meta might be trying to get ahead of with its next pair of glasses.
