iOS 6.0.2 and iPhone 5 battery drain
A recent update to iOS 6 was meant to target wi-fi
issues experienced with the iPhone 5. The new patch,
however, may have afflicted the new iPhone with
iPhone 4S-esque battery drain issues.
It’s deja vu all over again with respect to battery
drain and the iPhone 5. After the iPhone 4S release
was tarnished in 2011 with widespread battery drain
complaints — and initial grumblings from early
iPhone 5 adopters that Apple had not done enough to
improve battery life on the new iPhone — now, the
new iOS 6 patch appears to have negatively impacted
battery life.
According to a CNET report, iOS 6.0.2, which was
released largely to deal with some wi-fi issues
experienced by many users, has had some kind of
adverse effect on the software side of battery
usage, with a number of iPhone 5 users taking to the
Apple forums to complain.
Tech Radar:
“Curiously, the battery drain appears to only
affect the iPhone 5 and not the iPad mini, which was
also updated to iOS 6.0.2 this week; other devices
didn’t receive the minor update.
Initial speculation points to a change in Wi-Fi
antenna behavior under iOS 6.0.2, although this
theory doesn’t explain why most iPhone 5 devices –
and all iPad mini tablets – remain unaffected.”
There’s an obvious cause-effect going on here, with
the wi-fi fix affecting battery usage on the iPhone
5. Most likely, the patch is also having some kind
of effect on the iPad mini as well, but seeing as
the device has not been fraught with battery drain
issues in the past, the effect might be much more
subtle than on the iPhone 5, which sports an already
undersized battery.
It still remains odd that Apple has not aggressively
moved to improve battery design for the iPhone since
the release of the iPhone 4. The 4S saw no increase
or improvement in the device’s battery, and the
iPhone 5, while utilizing a slimmer battery design
to accommodate the device’s slimmer profile, did not
substantially increase its capacity, all while
outfitting the 5 with 4G LTE and other battery-
sucking hardware components.
A possible explanation for this design decision by
Apple is that Cupertino sees the iPhone user base
keeping their device docked more frequently
throughout the day, thus providing several daily
auxiliary charges that augment the nighttime charge,
thus precluding the need for higher capacity
batteries. Also, Apple’s software designers may feel
like they can continue to optimize iOS for battery
life, seeking a software solution to a hardware
problem – a long-held Apple ethic.
However, it can be argued that Apple has not done a
great job at doing this since iOS 5 and the 4S was
released.
With the eventual release of the iPhone 5S in 2013,
it is unlikely that the next iPhone device will see
any substantial overhaul of its battery. At the same
time, it’s also unlikely that the 5S will feature
new hardware components that would put an undue
stress on the current battery. Chances are,
Cupertino will make marginal upgrades to battery
capacity to meet the demands of the A6 chip.
One would hope, however, that eventually Apple is
going to take battery life seriously once again,
since a mobile device is only as good as its
battery.
