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.

Hello John I recently bought a kingpad tablet on ebay brand new and I barely use it for 15 minutes on a fully charged battery and after 15 to 20 minutes it’s already at 15% battery. I have done all your steps except install that app task killer. I hope it works. And the only thing that I try to modify and work with us the brightness setting because the color is weird and hard to see. I do my jigsaw puzzle game and just to see the right color of the puzzle piece I have to look at the… Read more »

Most of your issues can simply be resolved by using your phone all the way to 0% then charge it back up to 100% without going on it then once that’s done the battery should last way longer if not then maybe you dropped your phone or ur phone just doesn’t have that much battery life also could need a new battery

Since I did a reset to factory settings on my Android Moto X it changed my whole operating system and I don’t like it. I never gave it permission to change to 5.1. I’m not sure if it is lollipop or what. Battery drains in 5 to 6 hours. Could someone tell me what could have happened. I’m not too savy.

I think this is what is going on with me as well. I’m rushing through my data plan even though I’m using wifi at my house. I noticed data being used at 2:00 AM, and I was sound asleep! It doesn’t make sense.

Dear Skitzoidlady,

Thank you so much for your question and for reading my blog. I just posted a response to the question above yours, and I believe it will also be helpful for you. I’d love to hear your feedback because a lot of people are continuing to experience a problem with their iPhones using cellular data even when they’re connected to Wi-Fi, and if we work together I believe we can get to the core of the issue.

Best of luck and be in touch,
David P.

I discovered today that my iPhone is not always connected to my wifi. Even though I’m using my phone right next to my laptop, also connected to wifi, the laptop connects, but the iPhone sees no available wifi. Also, someone suggested to me to turn off LTE when at home, because LTE will take over, even when wifi is working. I did reset my usage, so I’m going to see how this all works.

Dear Dave, Thanks so much for your comment and I apologize for taking a while to get back to you. You have an excellent point and question, and I’d like to help you and other readers figure out why your iPhone is using data even when you’re asleep and (presumably) connected to Wi-Fi. I’ll cover two quick fixes first, and then I’ll go into what my gut tells me is really going on with your iPhones. First thing to try: Head to Settings -> General -> About, and remain on that screen for about a minute. Your iPhone will check… Read more »

Last night my tablet’s battery was getting low(20%) and I didn’t want to look for my charger so I hit the power button and selected ‘power off’ this morning when I turned it back on it was at 7%! Wth? I have an Asus memo pad, I didn’t upgrade so I think it’s still running jellybean. I set the WiFi to turn off when not in use and activate or deactivate the Bluetooth as needed. I might get the task killer, I hate this thing running stuff I’ve never used.
