There’s a lot of power contained within that little glass rectangle you
carry around all day. We’ve got eight-core CPUs, multiple gigabytes of
RAM, and batteries with thousands of milliampere-hours of capacity, but
sometimes the experience doesn’t live up to the hardware’s potential.
Things go wrong, settings get screwed up, and apps get greedy for
resources. This can render a phone sluggish and kill the battery. That’s
certainly a problem, but don’t worry, we can fix it in a few simple
steps.
Check for updates
You might just be running old, busted software.
Which updates? All the updates. If you don’t have automatic
updates activated in the Play Store, or you’re not connected to Wi-Fi
very often, you should run through all the app updates available to you
before taking more drastic measures. It’s possible some app or other had
a bad update and is causing mischief in the background. Getting the
newest version might solve your problems in mere minutes.
You should also check for system updates in the About phone menu in Settings.
You’ll likely get a notification when over-the-air updates are ready,
but not all carriers keep pushing them after you dismiss the alert. If
there’s an update available for your device, make sure you install it.
You can probably find horror stories about OS updates if you look
around, but these tales are in the extreme minority. Usually you’ll get
security fixes and (importantly) performance improvements.
Remove and disable apps
Get rid of unneeded stuff.
If you’ve been using a phone for a few months, you’ve probably
accumulated quite a collection of apps you rarely open. Maybe you think
you’ll use them at some point, but let’s be real, you’re not—ever. You
should go through your device and remove anything you don’t absolutely
need.
Android allows apps to start up and run in the background. That’s
usually not a problem, but some apps (as mentioned above) can misbehave.
Micromanaging background tasks is a recipe for disaster as any services
you kill will only restart themselves and drag the system down and
waste more battery in the process. Fewer apps installed means few
background tasks for Android to juggle. Simply removing apps you don’t
use could solve your problem. You might also be seeing sluggishness if
your phone is nearly out of space, so clearing it out can help in that
respect.
For unwanted system apps that you can’t uninstall, you should disable them from the main app settings (here’s how).
This hides them from the app drawer and prevents them from starting up
in the background. If these apps are bogging down your phone, problem
solved.
Clean up your home screen
Streamline your home screen to improve performance.
Most device makers have their own home screen, but there are also
various third-party alternatives and Google’s own Now Launcher in the
Play Store. One thing they all have in common is widget support. Widgets
are great, except when you get a little carried away and they make the
phone sluggish.
If you’re feeling a little too much lag, consider scaling back what’s
running on the home screen. It might just be one or two widgets causing
issues, so look for things that scroll or refresh often. Live wallpapers
can also cause a device to suffer poor performance, so switch to a
static one to see if that fixes anything.
Be smarter with power saving modes
Use power saving mode when it’s appropriate.
It’s 4PM, is your battery dead yet? Depending on the phone you’re
carrying around, you might have to answer in the affirmative. The power
saving modes included in virtually all phones can save a bit of juice
and extend usable time, but they come with drawbacks. For example,
they’ll slow the clock speed of your processor, and reduce the rate at
which the display is drawn. Unsurprisingly, that makes the phone feel
slower. It can be noticeable if you’re already dealing with performance
issues.
There’s a place for power saving modes, of course. When you’re actually
low on battery and longevity is more important than performance, sure,
turn it on. Most phones even have a setting to automatically enable
power saving modes at a certain threshold. Just don’t leave these modes
on all the time like some people do.
A full factory reset
The nuclear option.
Despite how amazing smartphones are, they aren’t perfect. Sometimes you
just don’t know what’s wrong, and no amount of tinkering settings and
apps will return a device to like-new performance. If all else fails,
you should consider doing a full device reset.
This can solve any problem you’re having with apps, but it can also
cure bizarre and impossible to diagnose system issues. It’s a bummer
that this sort of thing still happens, but if there’s some sort of
deep-down error or misconfiguration, this is probably the only course of
action you have.
Before you reset your phone, make sure you’ve got all the important data
saved elsewhere. You can save files in cloud services like Dropbox or
Google Drive. App data is harder to take care of, but Helium Backup is compatible with most devices and doesn’t need root.
You can initiate a device reset from the main system settings in the aptly named Backup and reset
menu. You can also boot into recovery mode and reset from there, but
that’s only necessary if your phone isn’t booting to Android properly.
If you do need to reset, hopefully you at least end up with a snappy
Android device at the end of it.
