The iPhone 18 Pro Max’s Battery Is a Beast, but Save $100 and Stick to Last Year’s Model

Why This Matters

Apple's iPhone 18 Pro Max pushes battery life to a claimed 45 hours of video playback for $1,299, a $100 increase over the iPhone 17 Pro Max. For most buyers who just need a phone to last a day, the older model likely delivers nearly the same real-world experience for less, a tension that matters as surveys show consumers prioritize price and battery above all.

Key Takeaways
Worth a Look

Anker MagGo Power Bank 10K — If you're sticking with last year's iPhone instead of chasing the iPhone 18 Pro Max's beastly battery, a magnetic power bank closes the gap for a lot less. Anker's MagGo snaps right onto the back of your iPhone for cable-free topping up, with a built-in kickstand for watching video while it charges.

Apple just leveled up its battery on its new premium iPhone. Is it worth the leveled-up price tag?

As expected, Apple unveiled the pricier part of the iPhone 18 lineup at its “Surprise and shine” event on Wednesday. The iPhone 18 Pro and Pro Max have some serious upgrades, like faster performance from the A20 Pro processor, a new automatically adjustable camera aperture with built-in AI software, and a larger vapor chamber.

But the big “wow” factor is the battery. We saw a big improvement in the iPhone 17 Pro Max, which wins as our best-tested battery. But the iPhone 18 Pro Max is a pretty sweet upgrade for $100 more than its predecessor’s original price.

During the event, Apple said you can get 45 hours of video playback and 30 hours of usage per charge with the new premium version. It’s also expected to have faster wireless charging, and 15 minutes of wired charging should put the phone at 50%. Comparatively, the iPhone 17 Pro Max has 39 hours of video playback. And based on our testing, the phone’s battery life reached 49% in 20 minutes.

The 18 Pro Max seems to pack a powerful punch with its battery. And surprisingly, Apple’s not raising the price too much. The iPhone 18 Pro Max starts at $1,299 for 256GB, which is only $100 more than the iPhone 17 Pro Max for the same storage. But are the battery upgrades worth the price? I don’t think so.

Sure, the iPhone 18 Pro Max has a better battery, but if you’re like me, you just want your phone to hold a battery for a day without rushing to a charger. If you’re not watching videos for days, you may not see much of a difference between the iPhone 17 Pro Max and the new model. Especially if you want a better battery on a budget.

A recent CNET survey highlighted what US adults really want in a phone upgrade. Most (55%) want a cheaper phone, and next to that is better battery life (52%). Truthfully, while the iPhone 18 Pro Max price increase seems small (especially given the RAM shortage), you may be able to get a solid battery for less.

I have the iPhone 17 Pro Max, and I’m not sold on the new model’s $1,299 price tag when its predecessor is bound to be cheaper soon. Shortly after Apple’s event, the iPhone 17 Pro and Pro Max disappeared from Apple’s site. But you still may be able to compare prices at other retailers and mobile carriers. We also noticed Apple quietly increased prices on other iPhone models, so it’s worth shopping around.

Apple’s Upgrade program and other mobile carrier trade-in programs may make the newer model cheaper. But if you’re buying outright or won’t get a deep discount, save yourself the money and get the older model that still holds a charge for the day.
