We may earn a commission from links on this page.In 2023, I decided to update my Apple Watch after consistently failing to wear my Series 4 for a number of years. I sold that one on Poshmark and began looking at newer models to find one with enough features to convince me to actually wear it. I opted to get a Series 8, although the Series 9 had just been released, as I was buying two: one for my mom and one for myself. As it turns out, that was a great decision.If you're searching for a new wearable or considering upgrading yours, you might also be wondering which of the older Apple Watch models is still useful today. My Series 8 is holding up beautifully three years after it was introduced, so I'm a big proponent of using older devices as long as possible. But not all Apple Watches will work as well as the Series 8 does in 2025. Don’t buy a watch Apple doesn’t support anymoreWe have to draw the line somewhere: Seven of Apple's watches are no longer supported, meaning they won't receive any software or security updates anymore. In addition, you run the risk that the watch will no longer be compatible with your iPhone or certain apps. In short, you shouldn't buy a watch that Apple doesn't support. That includes the following:Apple Watch Series 0Apple Watch Series 1Apple Watch Series 2Apple Watch Series 3Apple Watch Series 4Apple Watch Series 5Apple Watch SE (first-gen) While the company does currently support the Series 6, it is next in line to join this list. It's not clear when that will happen, but you can be sure it will. We'll see next week—when Apple reveals watchOS 26—whether the watch will be supported another year. If not, it'll be stuck on watchOS 11 for good.Performance and other generational Watch improvementsThere are considerations for older Apple Watch models that extend beyond their ability to simply run the latest operating system. With each generation, improvements are made in some form or another. For instance, the Series 4 introduced the ECG sensor, while the Series 6 introduced the blood oxygen sensor (though Apple had to disable the feature for the Series 9 and Ultra 2 in the U.S. due to a lawsuit). The Series 7 charges faster than its predecessors, and Apple has included fast charging on most watch models since (sorry, Apple Watch SE users).In general, each Apple Watch is faster than the last. Apple tends to put its newest S-Chip—the Apple Watch's processor—in its latest watch series. Simply put, a newer S-chip gives you a faster, more productive product. The Series 6 has an S6 chip, Series 7 has S7, and so on until you hit the Ultras. (The first-generation Ultra has an S8 chip like the Series 8, while the Ultra 2 has an S9 chip like the Series 9.)While there are some core features all currently supported watches share—like workout and swim tracking, sleep tracking, Apple Pay, ECG scanning, and the ability to read and respond to messages—newer models also each have some of their own special advancements and upgrades. Here's a brief list:The Series 7 introduced faster charging, a larger display, and more durable screen.The Series 8 brought temperature sensing, crash detection, and a low-power mode for conserving battery (as did the second-gen Apple Watch SE).The Series 9 debuted new gesture controls, on-device Siri access, more precise location tracking in Find My, and a display with double the brightness of the Series 8.The first-gen Apple Watch Ultra introduced a more durable titanium casing, custom shortcuts to apps and modes via the Action button, a depth gauge and water temperature sensor, more accurate GPS, a 36-hour battery life, and an emergency siren.The Apple Watch Ultra 2 introduced a display with a maximum brightness of 3,000 nits and on-device media playback. The Series 10 introduced the largest display available on a standard Apple Watch and faster charging. If you see a feature you absolutely need in a particular watch model, you'll have to spring for it. But if you just want something for core Apple Watch tasks, you can start to consider older options. Apple's watch comparison site can be a helpful tool for identifying different features among models. Battery degradation All tech degrades to some extent and the Apple Watch is no different—particularly when it comes to the battery. While there are ways to mitigate the problem, over time, the lithium-ion battery powering your wrist computer won't last as long as it used to. That might be a bigger issue than your watch's ability to download and support a new operating system. Apple's warranty doesn't cover batteries that wear down from normal use, and charges $99 for the repair, which you could instead put towards the purchase of a new watch. There is one exception: Battery service is free if you have AppleCare+ and your watch's battery holds less than 80% of its original capacity. You need to take your watch in to an Apple Store or service provider to have it tested. My watch was pre-owned, and while I have no way of knowing if it has its original battery, my battery life has not declined substantially in the two years I've been using it daily. I primarily use mine to track my workouts, vitals, and sleep, which means it's always running. I charge it while I'm in the shower and occasionally for a few minutes before bed, and that's about it. On an average day of constant notifications, mine lasts me a bit longer than the advertised 18-hour mark. Because I have little interest in the small improvements offered by the Series 9 and Series 10—like extra brightness, larger screen size, performance bumps, and advanced cycle tracking—the battery life is what would (or will) compel me to upgrade in the future, but for now, I have not noticed any problems. I asked my mom if she's noticed any battery degradation on hers, since I bought it at the same time and place as mine, and she said no. She uses hers to track walking workouts, talk on the phone, and monitor her sleep and vitals, too.Stick with the Series 7 or newerThoroughly consider which of the features on newer models are actually important to you before making any buying decision and, if you can, stay above a Series 7. The Series 6 is still functional, but, again, it's a matter of time until the company stops acknowledging that one completely. For now, I have been pleasantly surprised by how well my Series 8 has held up for two years. Its touchscreen has never faltered, the external buttons function perfectly, it syncs to all of my apps and devices with no problem, and it does exactly what I need it to do—which is to tell me how many steps I'm taking and how hard I'm exerting myself at the gym. If you're in the market for a smart watch, I see no reason that an older version shouldn't be considered, as long as it still runs the latest operating system. You can save a chunk of change by sourcing an older model from the resale or refurbished markets and put that money away for when Apple drops something super revolutionary in the wearable space. Apple doesn't sell anything below a Series 10 or SE directly anymore, so if you want a 6, 7, 8, or 9, you'll have to check the resale and refurbished markets. You'll definitely save some money that way (a new Series 10 starts at $399, though it can be found on sale, and the refurbished Series 8 I got is selling right now for $219).

Things have been quiet on the Apple Watch front lately. Too quiet. In fact, sales are down for the second year in a row, and just last quarter, Xiaomi overtook Apple to become the top wearable brand worldwide. The good news is that the Apple Watch line is due for a refresh. Here’s what’s coming. Apple Watch SE 3 (or what if: Apple Watch Series 11e?) It’s been almost three years since Apple announced the Apple Watch SE 2. It kept the same overall design from the original SE, got a 30% larger display, and gained the S8 SiP processor, giving it a 20% performance bump. This September, Apple is expected to announce its successor. Hardware and software While rumors have been circulating for the better part of the last several months about Apple replacing the current aluminum case with a “rigid plastic” case, these plans seem to have been shelved. While there haven’t been leaks regarding an increase in case or screen size, it would make sense to expect the options to go from 40/44mm to the current 42/46mm, or a bezel reduction, which would give it more screen real estate while maintaining the footprint. Expect also a SiP upgrade, bringing it on par with the upcoming Series 11 lineup, a much welcome upgrade against the current Series 8-era S8 SiP for the SE 2. Price Alongside the material change rumors, there had been rumblings about Apple lowering the price of its entry-level watch. However, that seems unlikely, given the recent tariff turmoil and the apparent reversal of Apple’s plans to change the material. It would be safe to expect the Apple Watch SE 3 to start at the same $249 as the current version, if not a tad above that, in case Apple decides to send the Apple Watch SE the way of the iPhone SE, and introduce a more expensive entry-level Apple Watch Series 11e. Apple Watch Series 11 2024 saw the 10th anniversary of the Apple Watch announcement. However, 2025 marks the 10th anniversary of its release. This gave Apple two opportunities to release a 10-year anniversary edition of the Apple Watch, and the company has already skipped the first. This September, it might skip the second. To be fair, it looks like Apple did have a plan to release a 10th-anniversary Apple Watch band, but the company seems to have given up on that as well. Hardware and software Currently, it looks like any significant changes to the next generation of the main Apple Watch line should come from within. Alongside a predictable S11 SiP chipset update, the Apple Watch Series 11’s biggest draws should be software rather than hardware-focused. Apple is slated to debut an AI-based health coach that will use data collected by the Apple Watch and from other sources to offer a comprehensive, tailor-made health guide. At the same time, watchOS 12 is expected to adopt the same visual cues that iOS 19, macOS 19, and iPadOS 19 seem to be destined to adopt from visionOS. As for dimensions, a size increase doesn’t sound likely, as the current 42/46mm options already feel too large for some customers, but don’t rule out a small bezel shaving for a few extra pixels in screen dimensions. Price Just like with the Apple Watch SE, it would be wise to bet on similar-if-not-slightly-higher price points to make up for the uncertainty surrounding tariffs. The current Apple Watch line starts at $399, so don’t expect anything below that. Apple Watch Ultra 3 Last year, while many expected Apple to announce an Apple Watch Ultra 3, it announced a satin black option for the Apple Watch Ultra 2. This September, though, it might be different. Hardware and software There have been no reports about Apple planning to move away from titanium with the new Apple Watch Ultra. So, like the Apple Watch Series 11, this year’s update will probably rely on new features as a differentiator from its predecessor. According to leaks by Mark Gurman, the next-generation Apple Watch Ultra is slated to get 5G connectivity, as well as high blood pressure detection. The latter, it seems, will work in the same way as Apple currently measures body temperature and sleep apnea: instead of offering real-time data, it offers a rough trend overlook and warns the user when something seems off. Also, Apple is working to add independent satellite messaging to the Apple Watch Ultra 3, which will definitely be a welcome addition to those who live up to the Ultra’s sales proposition. Price The Apple Watch Ultra 2 currently starts at $799, which is quite pricey. There’s no sign Apple plans to lower the price, and given the risk of surprise tariffs, it’s unlikely they’ll raise it either. This model is probably the most stable in the lineup when it comes to pricing, but if there is one thing we have learned these last few months, it is that nothing is set in stone.

A California-based company called Magrathea just turned on a new electrolyzer that can make magnesium metal from seawater. The technology has the potential to produce the material, which is used in vehicles and defense applications, with net-zero greenhouse-gas emissions. Magnesium is an incredibly light metal, and it’s used for parts in cars and planes, as well as in aluminum alloys like those in vehicles. The metal is also used in defense and industrial applications, including the production processes for steel and titanium. Today, China dominates production of magnesium, and the most common method generates a lot of the emissions that cause climate change. If Magrathea can scale up its process, it could help provide an alternative source of the metal and clean up industries that rely on it, including automotive manufacturing. The star of Magrathea’s process is an electrolyzer, a device that uses electricity to split a material into its constituent elements. Using an electrolyzer in magnesium production isn’t new, but Magrathea’s approach represents an update. “We really modernized it and brought it into the 21st century,” says Alex Grant, Magrathea’s cofounder and CEO. The whole process starts with salty water. There are small amounts of magnesium in seawater, as well as in salt lakes and groundwater. (In seawater, the concentration is about 1,300 parts per million, so magnesium makes up about 0.1% of seawater by weight.) If you take that seawater or brine and clean it up, concentrate it, and dry it out, you get a solid magnesium chloride salt. Magrathea takes that salt (which it currently buys from Cargill) and puts it into the electrolyzer. The device reaches temperatures of about 700 °C (almost 1,300 °F) and runs electricity through the molten salt to split the magnesium from the chlorine, forming magnesium metal. Typically, running an electrolyzer in this process would require a steady source of electricity. The temperature is generally kept just high enough to maintain the salt in a molten state. Allowing it to cool down too much would allow it to solidify, messing up the process and potentially damaging the equipment. Heating it up more than necessary would just waste energy.  Magrathea’s approach builds in flexibility. Basically, the company runs its electrolyzer about 100 °C higher than is necessary to keep the molten salt a liquid. It then uses the extra heat in inventive ways, including to dry out the magnesium salt that eventually goes into the reactor. This preparation can be done intermittently, so the company can take in electricity when it’s cheaper or when more renewables are available, cutting costs and emissions. In addition, the process will make a co-product, called magnesium oxide, that can be used to trap carbon dioxide from the atmosphere, helping to cancel out the remaining carbon pollution. The result could be a production process with net-zero emissions, according to an independent life cycle assessment completed in January. While it likely won’t reach this bar at first, the potential is there for a much more climate-friendly process than what’s used in the industry today, Grant says. Breaking into magnesium production won’t be simple, says Simon Jowitt, director of the Nevada Bureau of Mines and of the Center for Research in Economic Geology at the University of Nevada, Reno. China produces roughly 95% of the global supply as of 2024, according to data from the US Geological Survey. This dominant position means companies there can flood the market with cheap metal, making it difficult for others to compete. “The economics of all this is uncertain,” Jowitt says. The US has some trade protections in place, including an anti-dumping duty, but newer players with alternative processes can still face obstacles. US Magnesium, a company based in Utah, was the only company making magnesium in the US in recent years, but it shut down production in 2022 after equipment failures and a history of environmental concerns.  Magrathea plans to start building a demonstration plant in Utah in late 2025 or early 2026, which will have a capacity of roughly 1,000 tons per year and should be running in 2027. In February the company announced that it signed an agreement with a major automaker, though it declined to share its name on the record. The automaker pre-purchased material from the demonstration plant and will incorporate it into existing products. After the demonstration plant is running, the next step would be to build a commercial plant with a larger capacity of around 50,000 tons annually.

According to a recent investor note from GF Securities analyst Jeff Pu, Apple might have a pair of surprises in store for the iPhone 17 lineup this fall. Most notably, Pu has seemingly changed his prediction that the entire iPhone 17 lineup will use a version of the A19 chip. Instead, he now believes the base model iPhone 17 will use the same A18 chip that’s used in the iPhone 16. Pu had previously predicted that the entire iPhone 17 lineup would use the A19 chip and the differentiating factor would be the RAM. The analyst had said the iPhone 17 and iPhone 17 Air would have 8GB, while the iPhone 17 Pro and iPhone 17 Pro Max would have 12GB of RAM. Now, Pu claims that the iPhone 17 will use 8GB of RAM, while the iPhone 17 Air will feature 12GB of RAM just like the Pro models. Also in this analyst note, Pu says that all four iPhone 17 models will adopt a new metalens technology for the proximity sensor. The “metalens” technology may help Apple dramatically reduce the size of the Face ID sensor. Previously, Pu had said this change would only come to the iPhone 17 Pro Max. If it pans out, this means the entire iPhone 17 will feature a smaller Dynamic Island. Notably, this contradicts Ming-Chi Kuo, who reported in January that the Dynamic Island across the iPhone 17 lineup will be “largely unchanged” compared to the iPhone 16 models Here is Pu’s full breakdown of the iPhone 17 lineup specifications: SpeciPhone 17iPhone 17 AiriPhone 17 ProiPhone 17 Pro MaxLaunchSep-25Sep-25Sep-25Sep-25Display6.1″6.6″6.3″6.9″ProcessorA18 N3EA19 N3PA19 Pro, N3PA19 Pro, N3PDRAMLPDDR5 8GBLPDDR5 12GBLPDDR5X 12GBLPDDR5X 12GBFront Camera24MP, 6P24MP, 6P24MP, 6P24MP, 6PRear Camera48MP 7P, 12MP 5P48MP, 7P48MP 7P, Periscope48MP 1G+3P, 48MP 6P48MP 7P, Periscope48MP 1G+3P, 48MP 6PFace IDStructured lightStructured lightStructured lightStructured lightCasingAluminumTitaniumAluminumAluminumModemQualcommQualcomm or AppleQualcommQualcommCharging35W35W35W35WNPIFoxconnFoxconnFoxconnICT My favorite iPhone accessories: Follow Chance: Threads, Bluesky, Instagram, and Mastodon.  Add 9to5Mac to your Google News feed.  FTC: We use income earning auto affiliate links.
