The recently launched One Plus 3 phone offers its own
The recently launched One Plus 3 phone offers its own patented Dash Charge
technology with its 3000mAh and claims to offer one day's normal usage with 30
minutes of charging. The Le Max 2 which was reviewed earlier has a 3100mAh
battery backed by proprietary technology for a very short charge cycle. She is
now a student at Harvard and no one knows if she was able to commercially market
her brainchild. But there is one laggard inside your phone. The Asus Zenfone Max
which we reviewed on this page, has a 5000mAh battery and power saving circuitry
that controls processor performance as well as screen brightness to assure at
least 2 days on a charge.5 device is more phablet than phone. Batteries remain
the top pain point of phone owners, but some relief is coming.
The best the
industry can offer us is one of two options: bigger batteries or a faster way to
charge. And consider the technology: it has always been Lithium Ion for as long
as we remember: very similar to the Leclanche cell we studied in school -- but
with a compound of Lithium as the positive electrode, carbon or graphite as the
negative pole and a salt of Lithium as the semi fluid in between, to drive the
electric current. It is the battery that fuels your phone -- and a pretty lousy
job it has been doing -- till now.Batteries remain the top pain point of phone
owners, but some relief is coming.There's plenty of talk of new and alternative
materials -- but mostly they remain just that: talk. In other words, feed and
fatten the Li-ion -- or twist his tail to wake him up faster. Phones which run
on Qualcomm's Snapdragon processor can deploy that company's Quick Charge
technology, now into version 3. Dr Gordon Moore had predicted, 50 years ago,
that the performance of a semiconductor chip doubles every 18 months.
At
Loughborough University, they are working on fuel cells using hydrogen, which
theoretically should power a phone for a week. IBM made headlines last year
suggesting one could replace batteries
factory the heavy carbon rod with air, except that the normal air we breathe
is just not pure enough.Remember the simpler times when your phone did just
calls and text messages Once charged the device was good to go for ne week.
These days the battery in a 5 or 6 inch handset with fairly typical multimedia
usage won't last the working day.0, which promises to charge the phone 3 times
faster than with a normal charger.We may greet these stop gap solutions --
beefed-up on board batteries or reduced charge cycles -- with muted applause.
And at this year's Mobile World Congress, Oppo unveiled what it called Super
VOOC Flash Charge, which charges a 2500mAh battery in 15 minutes.Someone has
calculated that mobile phone capability seems to mimic Moore's Law. We will
reserve a full throated 'three cheers' till batteries become as clever at their
job, as the phone itself. So it seems, does the power under the hood of your
hand phone, with today's octa-core processor, an eight-fold improvement in 5
years. The Gionee M5 Plus sports a 5020mAh battery and claims 47 hours of talk
time and 12 hours of video playback.Another school of thought believes it is
better to accelerate the recharge cycle than beefing up the battery size (which
will inevitably make the phone bulkier).
Three years ago Eesha Khare, an
Indian-origin student in the US took a top prized at the Intel Science Fair with
her invention, a Super Capacitor that could charge an existing phone battery in
30 seconds.These days the bigger battery brigade has gone way beyond the typical
2000mAh - 3000mAh of a year ago: By month end Xiaomi will be launching the Mi
Max with a jumbo 4850mAh battery that promises to keep you going for 2 days
between recharges, not bad considering this 6.With no radical new battery
technology in sight, the best the industry can offer us is one of two options:
bigger batteries or a faster way to charge
