11 Tips to Boost Your Android Phone’s Battery Life

426123 android battery tips 300x169 - 11 Tips to Boost Your Android Phone's Battery Life

Top-notch Android smartphones like the Samsung Galaxy S5 and HTC One (M8) are powerful, but unfortunately, they don’t have endless battery life. In fact, many Android phone users would be happy to make it through a single day, hoping that a nightly recharge is sufficient.

Sadly, it sometimes isn’t. A number of factors have conspired to reduce gadget endurance over the past several years. Thinner designs with less room for batteries, larger and brighter screens, faster quad-core processors, more software that runs in the background, and power-hungry GPS radios all share responsibility. The move from 3G to 4G networks a few years ago—particularly of the LTE variety—has also taken its toll.

But there’s much more to poor battery life results than that. Fortunately, there’s plenty you can do to stem the flow of juice from your Android device. To write this article, I used a Google Nexus 5, as it’s running the latest version of Android 4.4 KitKat with no extra interface enhancements, but these tips should apply across just about any Android phone. Try these tips to extend your handset’s battery life:

1. See what’s sucking the most juice. Navigate to Settings > Battery to see an organized breakdown of what’s consuming your phone’s battery. Applications and features will display in a descending list of battery hogs. If you see an application you barely use or a feature you never use, you’ll want to uninstall the app or turn off the feature.

2. Reduce email, Twitter, and Facebook polling. Set your various messaging apps to “manual” for the polling or refresh frequency, just as a test, and you’ll instantly extend your device’s battery life by a significant amount. Once you see what a difference that makes, try re-enabling just the most important ones, and possibly reducing their polling frequency in the process.

3. Turn unnecessary hardware radios off. It’s great that today’s phones have LTE, NFC, GPS, Wi-Fi, and Bluetooth, but do you really need all five activated 24 hours per day? Android keeps location-based apps resident in the background, and the constant drain on your battery will become noticeable, fast. If your phone has a power control widget, you can use it to quickly turn on/off GPS (the largest power drain), NFC, Wi-Fi, Bluetooth, and LTE. On stock Android, swipe down to bring up the Notification bar, and then tap the icon on the top right corner.

4. Use the extra power saving mode if you have it. The aforementioned Galaxy S5 and HTC One (M8) both have Ultra Power Saving and Extreme Power Saving modes, respectively, that limits the phone to texting, phone calls, Web browsing, and Facebook. This can squeeze extra hours or even a day of standby time out of just a few remaining percentage points of battery.

5. Trim apps running in the background. From Settings > Apps, swipe to the left; you’ll see a list of apps that are currently running. Tap on each one to see what they’re for; you can stop any apps that you don’t need running in the background all of the time.

How Often Should You Reboot Your Android Device?

restart android 1 - How Often Should You Reboot Your Android Device?

Most people don’t reboot their phone very often.

Personally, the only time my phone restarts is when it runs out of battery life away from the charger or when something catastrophic happens. Neither of those things happens very often.

But should people like me and you reboot their Android devices more frequently? Or is it an absolutely pointless function that does nothing to help Android?

Let’s find out!

Reasons to restart:

-Installing important Android updates (not just app updates)

-You’ve encountered a serious error, slowdown problem, or other issue

-Your phone feels laggy and slow and you think restarting will help

-You’re rooting your phone and booting into development mode

Reasons not to restart:

-It takes a while

-It drains battery life

-You can’t use your phone for about 2 minutes

Tips to Save Battery Life on your Android Phone

Here’s a list of things you can do to make your phone not die on you by the end of the day.

Android Battery Life Tips

  • Delete it, if you don’t need it.

Like the heading says, delete all those apps you had downloaded once and simply don’t need now; an old game, a not so useful app, Delete them. Many times we end up stuffing our phones with hundreds of applications we don’t use. Most of these applications might keep your phone awake (a.k.a. not asleep) even when not in use. So the rule says, IF YOU DON’T NEED IT, DON’T KEEP IT!

(Go to Settings > Application Manager > Select Unwanted Applications > Uninstall)

For system applications, you can either disable them in the same Applications menu, else if your phone’s rooted, you can uninstall/freeze them with Titanium Backup or similar apps. Some known battery drainers are Maps, Google Now, Facebook, Google Talk. If you don’t need them, freeze them.

  • Turn off background updates in applications

Most applications when freshly installed have auto updates configured in the background. Some could be as regular as 10 minutes, effectively killing the battery even when you aren’t using it. Applications like Twitter, Facebook, Dropbox, Google Drive, Games, news feeds and the like often download large packets of data even over a basic edge connection and at times of poor connectivities, stopping the phone from going into deep sleep(power saving mode).

  • Turn off Haptic Feedback/Touch Sounds

Yes, we’ve loved those vibrations on our phone and the little ting ting sounds that remind us that we’re clicking that beautiful touchscreen. But thing this, every vibration activates a little motor inside the phone, every touch activated the speaker for a little while, and both of these LITTLE things extract the precious juice from the same battery that we blame for being not enough. So turn them off at the first instant.

(Settings > Sounds > Disable Haptic feedback | Lockscreen Sounds | Touch sounds | Dial Pad tones)

  • Use 3G/LTE only when needed.

Like I said, I don’t wish to deny you the benefits of having a smartphone. However, 3G/LTE drain battery much faster than 2G would. So at times when you’re not surfing the web/streaming a video/downloading a big file, you don’t need 3G. The upside here is a better battery life and a bearable notification system. There are also toggles in the Play Store that allow you to switch to 3G when screen is on, and 2G when not.

  •  Say NO to Task killers.

They claim to more than double your battery life, or keep the rogue apps in check. But if we’ve done the first step of this tutorial, they probably would also be deleted from your phone by now. If not, without contesting even one bit, removing them from your precious smartphone. They’re killing it. If you still don’t agree, read ahead.

Android’s basic functionality is to cache (keep in RAM in background) commonly used applications in the RAM, based on your frequency of use. While apps running in the background would cause battery drain, cached processes are not active processes and therefore don’t need to be shut down, contrary to what a task killer does. So every time the task killer is closing background apps, it’s countering the Operating system’s primary functionality of caching, which would hit in soon after again. It’s the vicious circle of killing and caching the application that shall drain the battery more than you expect. So if you have any such BATTERY SAVING apps, push them into the dustbin. Android doesn’t need them for sure.

  •  Turn of Auto Sync if you don’t need it (When at the laptop/When you’re sleeping)

A lot of us use auto sync for push mails, instant updates from various sources of information. While all of it makes the smartphone our primary device of use, I would suggest turning it all off when we’re around a laptop/computer at work or at home.

  •  Turning off sensors when not needed (GPS, Wifi, Bluetooth, NFC, etc.)

Let’s face it; we do forget to turn them off when we ain’t using them. Wifi/Bluetooth left on keeps scanning for available networks at fixed intervals, leading to severe unintended battery drain.

GPS kept on when indoors is another cause of battery drain. Everytime an application seeks location details; the GPS is put into action, but is unable to find any satellites, resulting in battery drain again. Turning off Coarse Network Location when not needed is another good idea to control battery drain.

  •  Screen Brightness

We love bright and colorful displays, with the superb high resolution LEDs and IPS LCDs being fitted into phones. But let’s face it, till there is a stable nuclear battery fitted into mobile phones that could last our lifetime, displays are going to be the biggest drainers on any smartphone. I wouldn’t suggest you to stop using those pretty devices. I would rather suggest you to regulate the brightness to levels that would keep the pretty displays going, and still save some juice when needed.

Most phones come equipped with ambient light sensors that automatically adjust the brightness according to the surroundings. You could either choose to let the phone do its magic by enabling auto brightness, or you could choose to tune down the brightness to levels where you don’t strain your eyes and at the same time, save some battery.

  • Add Power Control (Toggle Widgets) – Using 3G/LTE only when needed.

Add widgets to your desktop so you can quickly and easily toggle the battery drainers. The stock Android Power Control widget contains toggles for Wifi, Bluetooth, GPS, Sync and Screen Brightness. While these are probably all you ever need to toggle, I would suggest adding a 3G toggle if you are subscribed to 3G. Using 3G only when you need it and 2G while in standby should save you alot of battery too, and background syncs don’t really need a 3G data connection. Power Toggles and WidgetSoid are two free market options that work well.
