LG Optimus 2X review
Battery life was an important aspect for us with this phone, for obvious
reasons. Our happy discovery was that the Optimus 2X can keep up with the
current crop of Android multimedia powerhouses, perhaps even outlasting some
of the less frugal among them (Desire HD, we're thinking of you). This is
mostly down to Tegra 2 having a minimal power draw when idling. We managed
to cross the 24-hour standby mark on a day when we did about an hour's worth
of calls, a few minutes of HD video, and some sporadic music playback, all
while keeping push email notifications and the 3G and WiFi radios constantly
on. Note that for the majority of that time the screen was turned off and
the processor didn't really have much work to do, but the experience
illustrates that you can take a dual-core smartphone on the move, provided
you don't expect anything more from it than you would from its single-core
brethren. The camera turned out to be the biggest battery drainer, with
1080p decoding and encoding following up in close second, both predictable
outcomes. We can't conclusively say whether the Optimus 2X is more or less
power-efficient than its contemporaries -- efficiency being a function of
both power consumption under load and the duration of load times, the latter
being shorter on a faster chip -- but we didn't feel any more restricted by
its longevity than we did when using the likes of the Galaxy S, Desire HD
or Droid X, its direct competitors in the Android big leagues. |
