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

Why Does My Android Battery Die So FastWhether 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 SettingsQuick 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 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 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 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 is an option in 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.

Now that the first one’s out of the way, let’s fix some Crucial Settings that can extend your Android’s battery life significantly. The next tip is…

    Avast! states the Super Task Killer Free is Malware (Android:Helir-M[Trj]) …

    Anyone got any ideas?

      In my experience with Avast, it has many false positives, and doesn’t find actual viruses that other scanners pick up with ease. I scanned my phone with both Avast and with Sophos’s mobile app, and Sophos came up clean. Personally, I would trust Sophos much more, as their team of security experts is among the best in the world, and they are an enterprise class security company. If I were you, I would submit false positive feedback (as I did), and remove Avast and replace it with Sophos.

      If you are still trepidatious about it, try Advanced Task Killer.

      Good luck.

    Since the kit Kat software installed on most android phones I have noticed a significant decrease in battery. If u go into settings > accounts and click on your Google email address there are a TON of Google services running that I never use … such as “Drive”, “Google+”, “Google pictures”, “picasa”, and others. I returned off everything except contacts n calender n gmail along with suggestions above. It had a very positive impact on my battery…

    I guess I am stuck with a battery that dies quickly because I use everything that you listed except for Bluetooth which I already have turned off. I constantly use GPS, need WiFi on for the GPS, constantly use the phone to search the net and take credit cards from customers so I need 4G and Mobile data. However even if I was able to turn those off, wouldn’t that defeat the purpose of a smart phone? Lol…

    Here guys buy android but if you want to be able to use it then you have to turn off everything that makes it a smart phone. Lol

    Anyway, Thanks for taking the time to put up the tips.

      I was able to use all of those apps without worrying about my battery prior to my OS upgrade to 4.2.2. Now I can’t use my mobile data or wifi without the battery going “crazy” and draining rapidly. I can actually watch the charge percent tick down like a timer. Really weird.

    Something weird I’ve discovered about my HTC One X: when the battery is draining excessively fast, if I let it completely drain until it shuts down, then leave it off for a while and recharge, when back on it just sips the battery and lasts all day with plenty to spare. That is, if I leave off the Wi-Fi and Mobile Data. If I turn them back on, my battery drains very quickly and is quite warm…sometimes over 100 degrees. Thoughts?

      I often find that most phones will get warm while charging and using certain services. It’s an electronic device. The more it’s used, the harder it works. Any type of case/cover can make it harder for the phone to “breathe”. I find that when I make calls or run certain apps my phone will get very warm. It’s because that feature is using more processing power. A call will use significantly more processing power then a txt. My favorite game is very heavy and will not only cause the phone to warm up, it also causes my battery life to drain super quick.

    I am not the best with the latest devices but rather than let my 5 kids think they are so much smarter than me, I search for answers myself. My new phone died so fast I wanted to see how to help it last longer.I have since tried everything you’ve said and will let you know how it worked. My 21 yr old daughter has the same phone and she Facebook s alot and I see how it is a drain .I will share with her how I learned these battery saving tips from you soon, I just like watching her search for the phone charger, she looses it easily and needs to charge her phone just about daily.I maybe not be brighter than my kids on electronics but I am wiser, I ask questions and find answers ! Thanks John

      I appreciate all of the information you have taken the time to put together and share with us. I have a few questions.
      My HTC One X doesn’t seem to have an option to turn off 4G and use only 3G, just Mobile Date on or off. Is there some other way?

      • ETCollier
        June 14, 2014

        Another question: How do I know which apps are essential and which I can disable without disrupting the phone function? In my list of running apps are several that I am not sure of the importance of their function, such as ATT Ready2Go, Bluetooth Share, HTC Services, HTC Sence input, Google Play service, etc. Thanks for your guidance!

    Thanks for the tips. I’m not sure about uninstalling the Facebook app though – I use it regularly to “check in” and upload photos and share “Map My Walk” – can m.facebook.com be installed as an app with a button for easy access?

      Not all phones allow you to uninstall the FB app. you have two options: Continue using it (and have it drain your battery), or simply log out of the app (which will significantly increase your battery life). As for the shortcut, you can bookmark m.facebook.com, and then go into “Widgets” in your app drawer and add a bookmark widget to your homescreen. Hope that this helps.

        What do you say if i am not agree with your answer… You can uninstall the fb and what other pre-instaled aplication if you are interested just send me a messege.

          That is true, it is possible to uninstall the FB app, however, if it is included in the base image, the only way to do that is to root (and potentially brick/void your warranty) the device. While this is an option for some people, the average user who is simply looking for a quick fix for battery life improvement will want to avoid this, as it could end up doing more harm than good.

      You can’t on most non rooted devices, however you can disable apps you don’t want to use under settings > apps.

    […] PS. I recently asked my friend John, a technician who is as fanatical about Androids as I am about iPhones, to write a “sister post” about how to make Android batteries last a whole lot longer. He has some great insights, so if you or someone you know has an Android tablet or phone, they’d probably enjoy checking out John’s post: Why Does My Android Battery Die So Fast?

    You’re right, fb app is woeful, posts are out of chronological order, quite random. But it’s included in my plan for free. I guess accessing m.facebook.com would not be included in my plan?

    • John "Wiggums" Miller
      February 11, 2014


      It would be very odd if a particular app is included in your plan, as, typically, Cell Providers don’t break it down that far. What would be included is Mobile Data (3G/4G), under which navigating to m.facebook.com would be covered.

      I second John. Using m.facebook.com will absolutely be free if you use any of the major carriers like AT&T, Verizon, Sprint, T-Mobile, etc. – in fact, I can’t think of any exceptions.
