Why Does My Android Battery Die So Fast? The Best Phone / Tablet Battery Life Savers!


Whether you’ve got a Samsung, HTC, LG, Motorola, Google, or any other Android phone or tablet, issues with Android battery life almost always be resolved by addressing the one thing all these devices have in common: The Android Operating System. I’m going to explain the real reasons your Samsung, HTC, LG, Motorola, or Google phone or tablet runs out of battery so fast and show you exactly what to do to make your Android-based phone or tablet’s battery last a whole lot longer.

Before We Begin: Free Apps That Are Life-Savers

We’re going to be changing some settings on your device and the Settings menu on every device is a little bit different. If you’re having trouble finding any of the settings I mention below (or if you just want to make your life easier), I highly recommend that you head to the Google Play store and download these great free apps.

Don’t worry, I’m not getting any kickbacks for recommending these apps to you. I’ve used a bunch of battery life saving apps and these are the ones that I use on my own Android phone. If you’d rather skip the downloads and head right to the first Android battery life-saving tip, you can do that too!

Quick Settings

Quick SettingsSmart Quick Settings is a free app that allows you to change your device’s settings without delving through the complicated Settings menu. I’m going to keep things simple by telling you how to change your device’s settings using the Smart Quick Settings app. If you want to use the Settings menu on your device, feel free – all of these settings can be changed without downloading Smart Quick Settings, if you’d prefer not to.

Super Task-Killer Free 

super-task-killer-150x150Super Task Killer Free is a great app that gives you a quick, simple way to close out all of your apps at once. We’ll cover exactly why you’ll want to use it later on. For now, rest assured, it’s a huge time-saver, and well worth the download.

Now that you’ve opened up Smart Quick Settings, let’s walk through the settings that could be draining your battery without your knowledge. We’ll get to the more secret tips on the next couple of pages. If you’d like to skip ahead, feel free – but these are important!

1. Mobile Data – Turn Off 4G

If you have a smartphone, you’ll see Mobile Data as an option in Smart Quick Settings. If you don’t see it, that’s fine – just skip to the next section.

Do any of these situations apply to you?

  • Your carrier doesn’t have 4G coverage in your area
  • You do a lot of traveling between 3G and 4G coverage areas
  • You simply don’t need to use 4G (because you don’t stream video on the go)

If you answered yes to any of these questions, turn off 4G on your device. When you have 4G on and you’re not in an area with 4G coverage, your phone is always asking, “Is there 4G coverage here? How about here? What about now?”, and this constant searching uses a lot of battery life.

2. Turn Off Mobile Data Entirely (When You Can)

If you’re really struggling with battery life and you travel within areas with spotty coverage, try disabling Mobile Data entirely. You’ll still be able to receive texts and make phone calls, but you’ll save a lot of battery.

A friend of mine has a camp in the Adirondack Mountains in upstate New York, and whenever I travel there I make sure to turn off Mobile Data. A good rule of thumb: The worse the coverage, the faster your battery drains. This happens because your phone’s antenna has to work that much harder to try to find and maintain a signal.

Next up: One of the biggest battery Android battery life drainers, and it has to do with an app we all use: Facebook. I’ll give you the real scoop on why the Facebook app causes your battery to drain so quickly and what to do to fix it.

    If anyone is still having these problems you may just need to buy a portable charger, I just bought one for my girlfriend that she loves and its also a compact mirror with an LED light, you can find it at fifthandninth.com

    I have a galaxy s3 and i just purchased i new battery and it still drains so fast! I always keep my brightness at lowest it can go and i keep my data,wifi, Gps, etc. Always off unless of course im using it. The only thing i can think that might be causing it to drain is 1. Its just not a good battery from factory or 2. My apps are not closing out like you stated. Im going to download the task killer you said too and hopefully this will work. I downloaded an app called battery life repair which has really good reviews and its saying my battery is healthy and there is no issues, which i expected being that it is a brand new battery. Thank you so much for your helpful tips i definetly learned some things from your article.

    In the “about author” it says he loves the BBC. Does this mean something else or is this guy into black dudes?

  4. Myou galaxy Evant battery drains faster than it charges. Ex: right now it’s plugged in and when using it (for work) it continues to drain faster than it charges. Can u help

  5. I love my android phone, but the battery life on the tablet is so short it’s not even worth using so i basically spent $600 for nothing. Going to give these tools a shot, and if still no good, I’ll have an expensive photo frame!
