Most
smartphones today pack huge, high-resolution screens, powerful
processors and lots of memory to multitask and handle really complex
tasks. This also unfortunately means that they struggle to handle a full
day's worth of heavy usage, and so power banks are now a must-have
accessory.
The same can be said for our laptops, and the need to tether them to
the plug point grows as the battery ages. Most of our consumer
electronics devices come with Lithium ion and Lithium Poly batteries
that are geared for quick recharging, and not for long term life. Often,
you're better off replacing your battery instead of upgrading your
laptop, because of how quickly the battery ages.
Whether you're using a smartphone, tablet, or laptop, here are some
general purpose tips on prolonging its lifecycle and usage between
recharge cycles.
1) Keep it cool
Exposing the battery to high temperatures can be more stressful than cycling. According to
Battery University,
which runs an extensive array of battery tests - cycling, elevated
temperature and ageing decrease the performance of your battery over
time. Keeping your devices in a cool environment (battery dwelling above
30°C (86°F) is considered elevated temperature) will certainly enhance
the lifecycle of your device.

In
the testing, capacity dropped to 60 percent when exposed to 60-degree
temperature for three months, and 65 percent when the temperature was
40-degrees. For this reason, don't expose your gadgets to heat like
leaving them bake in the sun inside a car.
It's also a good reason to worry about heating issues on a
smartphone, as it can plunge the battery life quite drastically over
time. On a laptop, you should look at using a cooling pad to make sure
the CPU vent is being vented away. Exposure to dust can clog vents and
make your fans run on overtime, leading to an additional resource
burden, so keep the environment clean and dust free.
2) Go for paid apps, instead of free ones
Ad-supported apps reduce battery life by 2.5 to 2.1 hours on average, a study conducted by US-based researchers
revealed. To quote the study, a phone's processor is like its brain -
and ads eat up a lot of that brain power, slowing it down.
Not all free apps are draining your battery, but if you're seeing
advertising on it then assume it comes with a bandwidth and processing
burden. Spending a bit on apps might pay off handsomely, considering
some apps are available for as low as Rs. 10 on both Google Play and the App Store.
On a laptop, running a local application to do something like text
editing will consume less battery than firing up your browser and using
an online resource. So, if you're not using it, turn your Wi-Fi
connection off - on a Windows PC this is as simple as pressing
Fn+F2
on the keyboard. The exact function key can vary, depending on the
device manufacturer, so just look for a key with a Wi-Fi symbol next to
it.
3) Turn off location tracking
According to a recent news report, the Facebook app drains the
battery of iPhone users as it's constantly tracking the user's location
using the GPS module. Turning off location tracking for apps that don't
need your location will certainly help.
In most Android devices, you can head to
Settings > Location,
and toggle it off to disable location tracking entirely. The
functionality to set app level permissions is only enabled in Android M.
On iOS 9, go to
Settings > Privacy > Location Services and turn it off on a per-app basis, leaving location access on for just important apps, if you really need to.
4) Partial recharges are better than full-depth recharges
Another invaluable trip from Battery University can be explained
with the metaphor of a running a marathon. Instead of letting your
battery cycle all the way from 100 percent capacity down to zero,
keeping the depth of discharge to 50 percent of your battery capacity,
between 30 and 80 percent can increase the number of discharge cycles by
three times.
Lenovo internalises this principle in its Battery Maintenance
settings in the Power Manager bundled with their laptops, which can be
customised to power plans that best suit your needs. To optimise for
many years of usage,
Lenovo recommends you set the charge threshold to start at 40 percent capacity, and stop at 50 percent.
5) Turn down display brightness
This is an obvious tip that applies to both laptops and mobile devices.
On most devices, brightness settings are easily accessible, and you can
also apply screen dimming techniques through third party apps like
Lux, which overlays an opaque graphic to reduce brightness and change the colour cast of the screen.

However, a
software layer only saves power on OLED screens, while LCD screens can only save power by decreasing backlight brightness.
Reducing the amount of time your display stays on while inactive can
also save a fractional amount of battery life. In Android, this can be
accessed in
Settings > Display. On iOS,
Settings >
General >
Auto-Lock lets you tweak this setting.
On a Windows laptop, right-click on the battery icon and click on
Power Options. Change the setting to
Power Saver
to maximise battery life - Windows will lower the brightness, and
change the standby and other settings to prioritise battery usage
instead of performance.
6) Schedule app updates over Wi-Fi or when you are plugged in
In general, anything that is processor or bandwidth intensive is likely
to consume a lot of CPU power. For the best standby times it's best to
be stationary, and sipping on a Wi-Fi than your data plan. For this
reason, it's best to schedule app updates to happen only over Wi-Fi, or
if your device supports it, while you are plugged in.

This
setting can be accessed in Play Store app on Android. Launch the app,
then open the menu by swiping in from the left side of the screen. Go to
Settings > Auto-update apps, and select
Auto-update apps over Wi-Fi only. On an iPhone or iPad Wi-Fi + Cellular, go to
Settings > iTunes & App Store and turn
Use Cellular Data off.
7) Turn on low power mode
Not all Android phones have battery saver mode, but if you're on Android
5.0 or later (Lollipop) then you are likely have this feature. It
automatically kicks in when your battery hits 15 percent, and disables
background app refreshes, location tracking, and other syncing activity
to save on battery life. With Android Marshmallow, a new feature called
Doze puts your phone in deep sleep mode when it's lying unused for a
long time. This feature is apparently doubling standby times.
Unfortunately, if you're on an older phone, then you won't get the
feature.
With iOS 9, iPhones have a Low Power Mode that cuts down on
background refreshes, visual effects, and automatic downloads. This can
be accessed in
Settings >
Battery.
If you're using an older Android phone, then your phone's
manufacturer might have included its own Low Power mode feature - on
Sony phones for example, it's called Stamina Mode, while HTC calls it
Extreme Power Mode. There are also third-party apps you can try, though
in our experience, the built-in apps are more effective.
8) Discover flight mode
The phone's distance to a cellular tower is known to affect standby time
as well. So, if you're in a place with no network, it's best to turn
your smartphone into Airplane mode (called Flight mode on some devices)
to conserve battery life, rather than let your phone constantly seek a
tower.
Follow these tips and you'll find that your phone will last a little
longer between recharges - and the fewer recharge cycles you put it
through in a day the longer the overall battery life will be.
