We all have one common tech problem: Smartphones run out of battery way too quickly.
Smartphones typically last a full day. While there are smartphones with extra-large batteries that
can last more than a day — like the iPhone 6 Plus and the Moto Droid
Turbo — those are the exception, not the norm.
But the good news is there are many ways to strategically squeeze out a
lot more battery life from your phone just by adjusting a few settings.
1. Lower the brightness, turn on sleep
This is, perhaps, the most common battery-saving tip that applies to
any device with a screen. Keep your screen's brightness at 50% or lower
and your Android phone will last longer. You can adjust the brightness
by bringing down the notification shade with a two-finger swipe down
(sometimes it's a single swipe) from the top menu bar or by going into Settings > Display > Brightness level. And while you're at it, you may as well disable Auto Brightness (called Adaptive brightness on Android 5.0 "Lollipop").
The other feature within the Display settings that you can adjust is
the screen's sleep time, the amount of time the screen will wait while
it's inactive before switching off. It's usually set to 30 seconds, but
we recommend setting it to the quickest (15 seconds or less).
2. Figure out the power hog
Suspended apps — apps that are minimized but not closed — can still
consume a lot of power without your knowledge. Luckily, Android has a
built-in battery monitor. Go to Settings > Battery
and you'll be able to see which apps are the biggest offenders. Now,
you'll know which apps to avoid using when you know you're going to be
out all day.
3. Turn on battery saver mode
Not all Android smartphones have a power savings mode, but if your
phone does — Samsung, Sony, Motorola and HTC phones usually do — you can
turn it on when you're running low on battery. On some Android phones,
the power savings mode can be set to automatically kick in when your
battery dips below a certain percentage.
If your phone is running Android 5.0 "Lollipop," there is a built-in
battery saver mode, which can give it up to 90 extra minutes. It can be
accessed by going to the Settings > Battery > Battery Saver (in the menu icon on the upper right).
4. Kill NFC and Bluetooth
Bluetooth usually isn't turned on by default, but NFC might be. We've
set up many new Android smartphones only to discover the battery
secretly draining in the background because NFC was on.
NFC's a great way to connect an Android phone to things like
Bluetooth speakers and digital cameras with a single tap, but like
Bluetooth, you should only turn it on when you need it. Some Android
phones have an NFC icon in the notification shade. If your phone doesn't
have one, you can usually toggle NFC on/off by going into the Settings > Wireless & networks > NFC.
5. Use darker wallpapers
There two main types of smartphone displays: LCD and AMOLED. LCD uses
a backlighting system that illuminates every pixel on the display.
AMOLED displays, however, have pixels that are individually lit; a pixel
that turns into a color is lit, and thus, uses power. A pixel that
remains black, is not lit and doesn't use any power. If your Android
phone uses an AMOLED display (just about all of Samsung's do), you can
use a darker or all-black wallpaper to make your phone more
power-efficient.
6. Turn off GPS/location tracking
Many apps like Google Maps, Swarm and Yelp use your location to provide
real-time location data, but if you rarely use location-based apps or
use them sparingly, it would be wise to leave the GPS off. Some phones
have a GPS (called "location" on Lollipop) button accessible in the
notification shade. Otherwise, you can turn off location tracking by
going into Settings > Location.
7. Disable gimmicky gestures/features
This one's different for all Android phones. But if your device has
any silly features like eye-tracking or air gestures, as is the case on
the Galaxy S4, go ahead and disable them. There's a good chance you
won't ever use them and they're just sipping power in the background.
You can usually find toggles for these in the Settings app.
8. Turn off vibrations and unnecessary sounds
Haptic feedback — the vibrations you feel when you tap on an Android
phone's touchscreen — is great. I love the tactile sensation when I'm
typing on Android, but those buzzes activate the vibration motor, and as
a result suck up more power.
To turn off battery-sucking vibrations go to Settings > Sound & notification > Other sounds.
From there you can switch off the "Vibrate on touch feature," as well
as "Dial pad tones," "Screen locking sounds" and "Touch sounds"
— turning them all off nets you that teensy bit of battery that could
come in handy, say, during an emergency and your phone's about to die.
9. Keep widgets at a minimum
Widgets are a great way to see bite-sized info at a glance on the
homescreen or provide convenient shortcuts for things like music
controls. For the sake of better battery, kill the ones you don't use
often. You can remove widgets by long pressing on them and then swiping
them to the "Remove" (sometimes it's a trash can icon) that shows up.
10. Axe the animations.
Did you know that your phone's flashy animations and transitions are
decreasing your phone's battery? Good news, though: You can turn them
off and get some battery life back by activating the hidden "Developer
options" feature. Go to Settings > About phone, then scroll down to Build number and tap it seven times.
Hit the back button and you'll now see "Developer options" that
previously wasn't there. Scroll down until you see "Window animation
scale," "Transition animation scale" and "Animation duration scale."
Turn all three of these off and voila, your phone battery will last
slightly longer (and maybe even run faster). You may have to reboot
before seeing the changes.
