Apple Watch Series 6 teardown reveals bigger battery, Taptic Engine

Repair company iFixit has completed its teardown of the Apple Watch Series 6, revealing a refined design, a beefier battery, and a bigger Taptic Engine.

The Apple Watch Series 6 launched on Sept. 15 with a few key additions, including a blood oxygen sensor and new color options. As far as outward appearance, however, the device appears virtually the same as the previous Apple Watch Series 5.

On Monday, iFixit released its teardown of a 44mm GPS + LTE Apple Watch Series 6 variant. One of the first things that the site noted is that the new wearable opens to the side, rather than from the top. Opening up the device is also a bit easier because of the removal of Apple's Force Touch gasket. The pressure-sensing feature was removed in watchOS 7.

The 44mm Apple Watch battery has seen a jump to a 1.17 Wh capacity, which represents a slight 3.5% increase over the Apple Watch Series 5. Apple also bumped up the battery size on the smaller 40mm variant to 1.024 Wh, an 8.5% increase.

"Slowly but surely, Apple Watches seem to be clawing back capacity after the big drop from Series 3 to Series 4," the repair site wrote.

The new, brighter display on the Apple Watch Series 6 features slight design differences and simpler cabling. Apple also increased the Taptic Engine's size on the new Apple Watch model. The company didn't mention that addition, or the larger battery, at its Sept. 15 keynote.

As far as the brains of the new Apple Watch, iFixit notes that there are a few more conventional ICs installed on the package, as well as a Skyworks chip marked 239.7. None of the chips appear to be an exact match for Apple's U1, despite its inclusion on the model.

The slightly slimmer profile of the Apple Watch Series 6 is likely attributable to the modified case and removal of the Force Touch gasket. The frame also has a modified footprint with a narrower lip.

All in all, iFixit praised the removal of the "fussy" Force Touch gasket and the consolidation of fragile display cables to two. It also called the fact that Apple managed to fit a larger capacity battery and Taptic Engine into a slimmer frame "impressive."

"They just keep polishing this thing to a higher and higher gloss and it's almost sneaky how much of it they don't tell you about, keeping all the focus on the whiz-bang health features," iFixit wrote.

iFixit gave the Apple Watch Series 6 the same overall repairability score as the Apple Watch Series 5 — a six out of 10.

I hadn’t even realised the dimensions had shrunk. It’s even slimmer than my original model now. Coupled with the slight reworking of the lines of the case it looks pretty diminutive. I was already happy with the look of my series 4 on the wrist.  

Admittedly I’d have been just as pleased if they kept the dimensions the same and increased the battery even more.

I still tend to force touch „clear all“ in the notifications pane. However, since his was effectively the only force touch gesture I regularly used, I think that the gain of removing force touch is well worth its price.

The sound is also noticeably better, louder and voice much clearer and cleaner.  👍👍

I haven’t gotten mine yet. It’s frustrating. First they said the 25th to the 29th. Then they said the 28th, and the ups tracking also said that. Then ups said the 23rd, which was exciting, but it was still in China, so that would have to be fast air. But today the ups site took the date off and said I would be notified of a delivery date. Ugh!

I was hoping for more than a 3.5% bigger battery. When Apple came out with the always on feature last year, I turned it on. At first, battery life seemed about the same. But after a month, I came to see it wasn’t, so I turned it off. Now, they say the screen will be 2.5 times brighter when it’s using that feature. I doubt I’ll use it, though I’ll likely try it. I know they said the efficiency of the SIP is much greater, but I don’t see that as making much difference. I’d rather see at least a 10% increase in battery, and keep the Taptic Engine the same size. It’s fine now.

Apple’s engineering is definitely impressive. I’m interested to see what the real-life battery life ends up being. Bigger battery, but a bigger Taptic Engine and a brighter screen plus the pulse o. Sensor. What we don’t know is how the changes in watchOS and the chips will effect power use.
