Suggested March 2024 Apple Watch Series 4 Teardown: Stronger Battery, Doable Screen Replacements & More

Repair masters at iFixit earlier this morning published their detailed teardown analysis of a larger 44mm, cellular-equipped edition of the new Apple Watch Series 4 (model A2008).

“The original Apple Watch was revolutionary upon its release, but the yearly updates have been mostly minor—until now,” they noted.

Daring Fireball’s John Gruber has likened Series 4 to the leap in design brought by iPhone 4, prompting iFixit to actually call it Apple Watch’s iPhone 5 moment: “a device that knows its priorities, and wants to look elegant inside and out.”

Whereas the original Apple Watch model had the “awkwardly placed internals”, Apple’s engineers have “really painted the back of the fence” in terms of the component layout for the new Series 4.

The Crown with a secret

Cellular Series 4 models no longer feature a large red dot on the Digital Crown, which many people disliked. Now you get a far more subtle red ring outline that gives it an elegant feel. The completely reengineered 4 Digital Crown on the new apple Watch Series 4 also contains an electrode for a brand-new ECG function.

Series 4 has the most elaborate Digital Crown Apple’s create to date

A stronger battery & other tidbits

Even though it has a six percent slimmer case with less volume, Apple Watch Series 4 packs in a 1.113 watt-hour battery (291.8 mAh at 3.81 V) representing a four percent capacity increase over the 1.07 watt-hour battery powering the previous Apple Watch Series 3.

If only Apple found a way to miniaturize the Taptic Engine..

The Taptic Engine is now much thinner and a bit longer than before. I suspect a longer haptic feedback mechanism is needed for that faux spinning wheel feel afforded by the redesigned Crown. “Even this smaller engine takes up a lot of room in this tiny device—room that could have gone to a bigger battery, but Apple seems to feel physical feedback is very important,” iFixit notes. And whereas Series 3 has an unsightly hole in the case for its barometric censors, Series 4 cleverly uses the grille holes.

As you know, Series 4 also rocks a thinner, about 15% larger display.

X-rays reveal optical sensor in the middle, surrounded by a new ECG electrode

According to iFixit, the 44 mm model’s display covers 977 square millimeters versus 740 square millimeters on the same-sized Series 3 model. The 40mm model of Apple Watch Series 4 spans 759 square millimeter compared to 563 square millimeters on the predecessor.

This golden ring is likely a streamlined antenna

From the conclusion:

The corners are noticeably rounder for more of that squircle look.

The side button now sits flush with the case.

Series 4 is a Lead I ECG: it only measures voltage between the right and left arms.

Battery replacements are pretty straightforward, once you’re inside.

Band replacements remain fast and simple, and are even backward-compatible with previous models.

Screen replacements are difficult but doable: it’s the first thing to come off, and detaches via simple ZIF connectors.

Like with previous Apple Watch processors, the new S4 chip is still a system-in-package solution that combines a tiny microcomputer with logic boards, microchips and other components crammed onto a single resin-protected component, a first in the smartwatch industry.

The S4 chip is secured only with screws, unlike the fiercely-glued chips of years past

iFixit notes that several component flex cables are mounted directly to the S4 package, requiring skilled micro-soldering to replace. The resin-encased housing, however, makes most board-level repairs impossible.

Series 4 repairability

“Where the first Watch was awkwardly layered together and used too much glue, the Series 4 feels much more thoughtfully laid out,” the iFixit team observed.

Series 4 has neared iPhone levels of repairability, but iFixit said that a sticky display remains a challenge. In terms of batter replacements, once you’ve actually managed to make your way inside the device, the battery is straightforward to replace.

The aforementioned architectural and engineering improvements have prompted the iFixit team to give Apple Watch Series 4 a solid 6 out of 10 on their repairability scale.

Apple Watch Series 9: Everything We Know So Far

Ryan Haines / Android Authority

Update, June 26, 2023 (11:17 AM ET): We have updated our Apple Watch 9 rumor hub to include information about a new UWB chip that could make it to the next Apple Watch.

Original article: The Apple Watch goes into 2023 as the king of smartwatches. With the refreshed Watch SE and new Ultra model, it seems that the lineup might keep that crown for a while to come. The Series 8 didn’t set the wearable world alight, playing second fiddle to these two newcomers, leaving the incoming Apple Watch Series 9 with much to do to keep pace. So, what can we expect from the next model? Read on for all the latest details.

The Apple Watch series is due for some significant changes.

Color options are a little less predictable. Apple offered Starlight, Midnight, silver, and (Product) Red colorways for those picking the aluminum chassis. Steel-bodied watches could be had in a more professional silver, graphite, or gold finish. Expect many of these shades to return. However, we’d like to see the Series 7’s green and blue options make a comeback.

As for sizes, the Apple Watch has traditionally offered two dial sizes with its core Series watch. For the Series 8, buyers could opt for a 41mm or 45mm face.

The Apple Watch Series is due for some significant changes.

There’s another rumor relating to the watch’s screen. Research firm Omdia claims that Apple is working on introducing MicroLED panels to its Apple Watch models, but it’s unlikely that these screens will arrive in time for the Series 9. Notably, it’s believed that the panel in question could debut on the next Ultra model, skipping the standard Series line. Mark Gurman also believes Apple may bring MicroLED tech to the Ultra series but suggests this change might only happen in 2024. If accurate, this leaves the Series 9 with AMOLED panels and likely without screen size changes.

In a Twitter post, Apple analyst Ming-Chi Kuo revealed that Apple could aggressively improve hardware specs across devices to make the Vision Pro fit within its interconnected ecosystem. To accomplish this, Kuo points out that Apple may upgrade its Ultra Wideband (UWB) chip and include that chip in a variety of next-gen devices, which may include the next Apple Watch.

Some would argue that the Apple Watch’s most noticeable flaw is the battery life. While Apple regularly undersells its batteries’ capabilities, we’d still prefer a longer-lasting smartwatch.

Apple tends to adopt the software optimization approach over adding more capacity. Therefore, we don’t expect there to be any massive capacity gains with the Series 9. However, if the Apple Watch is to gain a new chipset based on the A15 Bionic, it should result in considerable efficiency gains.

In reality, the Apple Watch battery estimates are conservative at best. We could easily eke out a day of usage with the Series 8 during our review, more than the 18 hours quoted by its maker.

Will the Apple Watch Series 9 be worth it?

Ryan Haines / Android Authority

It’ll take a catastrophe to displace the Apple Watch from our best list. One of our biggest criticisms of the Series 8 was its lack of tangible improvements over the Series 7. Apple markedly improved the device’s strength and added a temperature sensor, but that leaves little reason to upgrade.

Provided Apple sticks to its $399 asking price, we think the Series 9 should be the best way for those seeking a reliable fitness tracker to join the Apple ecosystem. However, if it gets any pricier, the (potentially discounted) Series 8 starts looking even more attractive.

Apple Watch Blood Sugar Measurement Coming In Series 7, Claims Report

A Korean report claims that an Apple Watch blood sugar sensor will be included in the Series 7 device, when it is launched later this year.

With health applications a major selling point of the Apple Watch, it has long been expected that the Cupertino company would want to expand its medical capabilities …


When Apple first launched the Apple Watch, the company primarily marketed it as a convenient way to view and respond to notifications. It fairly quickly became apparent, however, that it was the health and fitness features which were driving sales, and Apple adapted its messaging and product development focus accordingly.

CEO Tim Cook had initially suggested that the company would be cautious in adding medical capabilities to the watch, as it feared that the need for FDA approval could hold back innovation.

We don’t want to put the watch through the Food and Drug Administration (FDA) process. I wouldn’t mind putting something adjacent to the watch through it, but not the watch, because it would hold us back from innovating too much, the cycles are too long. But you can begin to envision other things that might be adjacent to it — maybe an app, maybe something else.

Responding to customer demand, however, Cook changed his mind. The company added ECG functionality to the Watch in 2023, including Afib detection – and last year saw blood oxygen saturation added to the capabilities of the Series 6.

Apple Watch blood sugar sensor

A blood sugar sensor would be an obvious next step. The American Diabetes Association estimates that more than 10% of Americans have diabetes, and that over 26 million of them are undiagnosed. Adding a blood sugar sensor to the Apple Watch could play a hugely valuable role in prompting formal testing, diagnosis and treatment.

An ET News reports claims that both the Apple Watch Series 7 and Samsung Galaxy Watch 4 will be able to measure blood sugar when each is released later this year.

Samsung Electronics will be equipped with a blood glucose measurement function in the new smart watch ‘Galaxy Watch 4’ (tentative name) to be introduced in the second half of this year. It is a no-blood sampling method that detects the level of glucose in the blood without blood collection using an optical sensor, and is expected to contribute to the health management of the general public as well as diabetics […]

Not only Samsung Electronics, but also Apple is applying the blood glucose measurement function to the Apple Watch 7 to be introduced this year. With the related patent technology secured, it is focusing on ensuring reliability and stability prior to making the technology available.

It’s not clear at this stage whether the existing infrared sensor will be able to act as a blood glucose detector too. You can already buy affordable home test devices that sync to your iPhone and Apple Watch, but these rely on small pin-pricks. The current focus is on non-invasive detection, and this can be achieved via infrared sensors.

The heartrate sensor in all Apple Watches is capable of acting as an O2 sensor, but Apple reserved this feature for the Series 6. Even if it turns out that the same sensor could measure blood sugar too, the company may take the same approach and make it a Series 7 exclusive feature for marketing reasons.

Apple Watch Series 7 May Come In Larger 41Mm And 45Mm Sizes

In the near future, Apple is more than likely going to host an early September media event to show off a range of new devices. While most of the attention will obviously be put on the new iPhone lineup, that’s not all we’re going to see if the rumors pan out. For instance, we’re probably going to get a new Apple Watch –the oft-rumored Apple Watch Series 7— and Apple may welcome brand new sizes to the lineup.

That’s according to a new rumor propped up by a user on the Chinese social media platform Weibo that goes by the name UnclePan. This account has shared some accurate information in the past, as noted today by MacRumors, so we shouldn’t discount this latest rumor by default. That being said, nothing is official quite yet. And even if Apple has plans to change the Apple Watch’s case size at some point in the future, plans could change. That means this latest rumor might not pan out, either — at least not this year.

That being said! According to UnclePan’s post, Apple is going to change things up this year a little bit more than just a new case design. The poster says Apple is going to adopt two larger sizes this year, bumping things up from 40mm to 41mm and from 44mm to 45mm. So, not a huge change by any means, and some people might not even notice at all. However, with so many rumors swirling around that Apple is going to change the design of the Apple Watch this year, the change in size certainly seems possible.

The size options for the Apple Watch haven’t changed significantly over the years. For several years, Apple offered the smartwatch in either 38mm or 42mm sizes. With the Apple Watch Series 4, which welcomed a larger screen size, the company welcomed 41mm and 44mm case sizes. So we’ve seen bigger changes in the past, but this year’s is probably noteworthy insofar that it will come along with a more significant case redesign.

The question remains: will existing Apple Watch bands work with the new case sizes? Apple has done a pretty admirable job making sure the old watch straps work with the newer case sizes, so one has to hope that remains the case this year, too.

As for the new Apple Watch Series 7, the new smartwatch is expected to welcome a new case design compared to the previous models. That starts with the sides, which are expected to be flatter than the current model. (Think in line with the current iPhone 12 series as a reference point.) From there, the new smartwatch is said to have smaller bezels, too. Apple will also reportedly adopt a new green color into the lineup as well. We recently saw CAD-based renders of what the new Apple Watch may look like, and it’s certainly an eye-catching design. It will be fun to see how it looks on stage, and then, ultimately, in the real world. The new smartwatch is expected to welcome a slightly larger battery, too.
