If you are like most folks, you remember how you had to structure
your day around keeping your mobile gear running away from the power
outlet.
Phones were likely to start running empty long before day's end.
Laptops had to be topped off at an outlet at some point during the day
to have any chance of lasting long enough. Even the newest member of the
mobile family, the tablet, could start coughing before being put to
bed.
That's all changing rapidly, and it won't be long until mobile device
users will not even think about the time remaining on the battery.
We are on the brink of having acceptable battery life on almost all
mobile devices, and we've gotten there in just the last couple of years.
This improvement is the result of a number of advancements that work
together to make gadgets run longer. While battery technology has
improved incrementally over the years, it hasn't improved enough to
deliver this advancement on its own.
It's largely hardware improvement that plays a great role in keeping
gadgetry running for long hours. Processors used in mobile devices,
Intel and ARM in particular, have gotten good at gently sipping from the
power trough. Plus, the switch from moving hard disks to low power
flash memory has factored heavily into the overall reduced power
requirements of most mobile devices.
The Intel Haswell chipsets should make a big push to longer battery
life. This will have a tremendous impact on both laptops and tablets.
Software has factored into the improved battery situation too, as
platform developers have learned how to make operating systems with a
lesser impact on power consumption. Programs running all the time in the
background have especially improved to keep power usage down to a
minimum.

The improvement in hardware and software in the mobile space have
worked together to greatly reduce the load on the small batteries tucked
inside gadgets. This goes hand in hand with device makers that have
developed manufacturing techniques eliminating the use of brick type
batteries, in favor of free form cells that can be fitted to the sealed
casing now in favor. This allows cramming the biggest battery possible
in any given gadget.
Extended battery life is quite noticeable in tablets, with many
models offering 10 hours or more on a charge. This allows even the
heaviest user to get through a whole day without the need to carry the
power adapter.
This is significant as tablets are awkward to use while plugged into the wall.
Phones have historically been the worst mobile devices as far as
battery life is concerned. It wasn't that long ago that it was almost
impossible to get through a full day without either using extra
batteries or plugging the phone in to charge. Car charging adapters were
in virtually everybody's car.
That's not the case anymore, as most phones can go all day on a
charge. Days of unusually heavy usage might stretch it to the limit, but
most of the time it's all day performance.
Laptops might be the most improved category of mobile device when it
comes to battery life. Most probably remember when three hours of heavy
usage could drain a laptop dry. Getting through an entire day wasn't a
consideration for the laptop; work days were planned around having an
outlet nearby at some point.
All of that is a thing of the past with mobile gear. Tablets last
10-12 hours, phones pretty much all day, and laptops approaching 10
hours of constant usage on a charge. It might not be all day battery
life but it's darn close. With just a little additional improvement we
should soon see all mobile device owners leaving the power adapters
behind, without giving it a second thought.
