How undignified: The iPad Air 2 —
the world’s thinnest tablet!
— has only been officially released for a few hours, and already the
brutes at iFixit have torn down Apple’s new fondleslab to find out what
magical gubbins lie within. Most notably, the teardown reveals that the
iPad Air 2 is thinner and lighter than the original Air because… it has a
much smaller battery. This explains why the listed battery
life for the iPad Air 2 is the same 10 hours as the Air 1 — and why, in
practice, some reviews have found that the new Air 2 actually has less
battery life than its predecessor. Curiously, the teardown also found
that the iPad Air 2
does have an NFC chip — even though reviews of the tablet show that NFC isn’t available.
Just like the original iPad Air,
iFixit found that
the iPad Air 2
is almost unrepairable, netting a Repairability Score of just 2 out of
10. Like the original iPad Air, the only way into the device is by
removing the screen — and there’s so much adhesive that there’s a
significant risk of cracking the display while trying to leverage it
out. The Lightning connector is still soldered to the logic board, too,
meaning it can’t be easily or cheaply replaced — and yes, removing the
battery and its oodles of adhesive glue goo still requires a lot of
fiddly elbow grease.
Speaking of the battery, the
iPad Air 2 now has a 27.62 Wh (watt-hour) battery, as opposed to the
32.9 Wh unit in the original iPad Air — a reduction of about 17%.
Amusingly enough, that reduction is almost exactly tied to iPad Air 2’s
thickness, which is 18% thinner than the original iPad Air (6.1mm vs.
7.5mm). Apple maintains that the iPad Air 2 is still capable of the same
“10 hours of surfing the web on Wi‑Fi, watching video or listening to
music,” but some reviews have found that there is indeed a battery life
hit.
Recode,
for example, found that the iPad Air 2 lasted 10 hours and 37 minutes
in a battery life benchmark — a full 86 minutes less than the 12 hours
and 13 minutes of last year’s iPad Air 1.
Rounding out the rest of
the teardown, iFixit found the same NFC module that’s present on the
iPhone 6 and 6 Plus, 2GB of Elpida RAM, and a new 8MP iSight camera
that, despite the same name and pixel count as the camera on the iPhone 6
Plus, clearly isn’t the same piece of hardware (which explains why the
iPad Air 2 still doens’t take great photos). The WiFi antennas have been
moved to the top of the iPad Air 2 (they used to be along the bottom),
which should improve reception a bit. The NFC module is a bit weird,
considering the iPad Air 2 apparently (according to both reviews and
Apple) doesn’t have
NFC/contactless payments enabled. Maybe Apple will enable NFC at a later date?
So, there you have it: If you
were wondering how Apple could make a very thin and light tablet even
thinner and lighter, it wasn’t some magical feat of engineering — they
just made the battery thinner. Apple was obviously hoping to compensate
for the smaller battery with
the new A8X SoC
— and no doubt some other small system-wide power savings elsewhere —
but seemingly didn’t quite pull it off. It’s worth pointing out that the
iPad Air 2’s 10-hour battery life is still comparable to other flagship
tablets on the market — but it
is somewhat ironic that it’s beaten by last year’s model.
As I’ve said before, our shift towards mobile computing is still
very much hindered by battery tech;
displays are still doubling in resolution every few years, and chips
are posting huge power reductions year over year, but at least for the
foreseeable future,
batteries are moving very slowly. If you want faster smartphones and tablets, and brighter and higher-resolution screens, battery life
is going to take a hit — there’s currently no two ways about it, and there probably won’t be for many years to come.
