iPhone 17 Rumors: New iPhone Battery Could Be Stronger and Smaller

Speculation on better battery life and charging could give a power boost to the rumored iPhone Air.

The next iteration of iPhones is just around the corner, with an official announcement expected sometime this fall. With the Worldwide Developers Conference now behind us, we’re most looking forward to the announcement of the iPhone 17.

There are plenty of rumors about what the next iPhone will look like and what sort of specs it may have. One of the more popular talking points for any new smartphone release is battery life, and the new iPhone is no exception. A rumored iPhone 17 Air with a thinner design has raised the question of whether a slimmer iPhone would have to sacrifice battery life.

Regardless of the model type, battery life is a concern across the board. After all, you can’t use your new tech if the battery drains too fast and doesn’t last more than a few hours. We’ve sorted through all the rumors and leaks when it comes to the battery for the iPhone 17. Let’s break it down.

Battery size for the next iPhone

Current iPhones utilize a lithium-ion battery, which is less malleable and not really conducive to being used in a slimmer model, like the rumored iPhone 17 Air. So, if they were to shrink the lithium-ion battery to fit a skinnier frame, it would likely have less capacity. However, Apple may be adding a silicon-anode battery to the new slimmer iPhone, according to AppleInsider.

Compared with graphite-based anodes, common in lithium-ion batteries, silicon anodes can hold more lithium ions, allowing them to store more energy. In theory, that would mean a more compact silicon-anode battery wouldn’t sacrifice power. The iPhone may even charge faster than previous iterations as a result. As for the rumored iPhone 17 Pro Max, according to 9to5mac, it’s expected to have a slightly larger battery than the iPhone 16 Max Pro.

AI-powered battery management

The next iPhones (and the current models after iOS 26 rolls out) will have AI-powered adaptive battery energy management starting this fall, we learned at WWDC. Part of Apple Intelligence, the company will utilize AI to monitor how you use your device and adjust performance and energy consumption settings accordingly, aiming to extend the phone’s battery life. Think of Adaptive Power as the first step toward extending your iPhone’s battery life and Low Power mode as the last step of doing the same.

Another piece of new hardware that’ll likely impact battery efficiency is the rumored A19 processing chip. The iPhone 17 base and Air will likely get the A18 chip, which is the same chip that the iPhone 16 uses. However, according to Apple analyst Jeff Pu, the rumored iPhone 17 Pro and iPhone 17 Pro Max are set to include the A19 chip, which would likely come equipped with better optimization, which in turn could impact how long the battery will last on the rumored iPhone, and how efficiently it will run.

How accurate are iPhone rumors?

Until Apple officially releases its new phone, speculation on the iPhone 17 is simply educated guesswork. While most rumors come from insider knowledge or are leaked from the teams working on these products, until Apple says otherwise, they remain rumors.

This Two-Faced Watch Band Lets You Hide an Apple Watch Under Your Rolex

The $418 Smartlet literally bridges the gap between your elegant analogy and your nerdy smartwatch.

The Consumer Electronics Show is never short on ambitious ideas, but Smartlet may be one of the more unusual ones this year: a modular watch strap that lets you wear a traditional mechanical watch and a smartwatch on the same wrist, simultaneously. One on top of the other.

The Paris-based startup announced Smartlet at the 2026 CES in Las Vegas, pitching it as a solution for people who love the look of an analog watch but also want the practicality of a smartwatch for notifications, fitness tracking and mobile payments. Instead of choosing between the two, Smartlet’s system lets you mount an old-school timepiece on the front of your wrist while hiding a smartwatch or fitness tracker on the underside.

The stainless steel strap starts at $418 and doesn’t include a smartwatch or a mechanical watch. What you’re really buying is the strap system, which is compatible with most major smartwatches and fitness trackers, including Apple Watch, Samsung Galaxy Watch, Google Pixel Watch, Garmin models, Fitbit Charge devices and Whoop. On the analog side, it supports watches with lug widths from 18 to 24 mm, which includes high-end models from brands such as Omega, Tudor, TAG Heuer and Rolex.

The idea comes from founder David Ohayon, who says he was tired of having to play favorites every morning, choosing between his analog and Apple Watch. Smartlet, in theory, offers the best of both worlds, letting you toggle from fitness nerd to polished executive with the flick of a wrist.

In practice, it raises some serious questions, the biggest one being bulk. Smartlet says the system adds between 9 and 12 mm of height to the underside of the wrist once a connected device is attached. As someone who already manages to scratch watches without trying, the idea of strapping a second device to the underside of my wrist, where it regularly comes in contact with desks, armrests and tabletops, sounds like a walking nightmare.

There’s also the aesthetic. Smartlet is clearly aimed at what it calls the «modern gentleman,» with marketing language that leans heavily into luxury watch culture and phrases like «from the boardroom to the weekend.» Translation: This is a watch for wealthy men who want to show off their investment piece without sacrificing their gym gain tracking.

And while it may not be the most practical, or budget-friendly solution for most people, Smartlet is one of those highly niche, standout products that had us doing a double take at this year’s CES.
