How to save battery life on your Android phone

My first Android phone was the original Motorola Droid, which I purchased and loved using despite its abysmal anti-woman marketing campaign. And one of the things I loved about it was that it had an interchangeable battery. I always kept an extra charged battery on hand, and simply swapped them out when needed. It was a lot more convenient and lightweight than dragging around a heavy battery pack, and kept the phone going strong over the course of the busiest workday.

But as phone designs changed over the years, swappable batteries were abandoned by phone manufacturers to keep their phones sleeker and to accommodate wrap-around screens. Batteries are getting stronger, but phones are also getting more use. So despite advances in power technology, your phone may still run out of power before the end of the day — especially if your device is a year or two old.

If you’re experiencing that problem, you’ve got a few options. You can buy a new phone (unless you still like your current phone, or if your budget is limited). You might also be able to have the battery replaced, depending on which phone you have. (If you have an iPhone, it tends to be easier.)

Or you can follow these tips to help you monitor and extend the usage of your battery.


Introduced in Android 6.0, Doze Mode makes sure that the apps in your phone aren’t using battery power when you’re not using your phone. There’s nothing you have to do — Doze Mode automatically kicks in when your phone has been unplugged and motionless for a certain length of time. At that point, certain apps are denied access to the network, and their processing jobs (such as checking for updates or for news) are halted, except for periodic moments when they are allowed to access the network for updates and syncs.

In other words, when your phone isn’t being used, many of your apps get to take a nap until you need them again.

Now, you may not want all your apps to experience Doze Mode. If you have an app that is constantly updating for your job, you may want it to continue working even when you’re not using the phone. Here’s how you do that:

  • Go to your phone’s settings and select “Apps & Notifications.”
  • Scroll down and select “Advanced” > “Special app access” > “Battery optimization.”
  • You’ll see a list of all the apps that are not optimized for Doze mode. Tape on the “Not optimized” button on top and choose “All apps.”
  • Most (but not all) of your apps will be labeled “Optimizing battery use.” You can go down this list of apps and choose any app that you want to exempt from Doze Mode. When you see one that you want to exempt, tap on the name of the app and then select “Don’t optimize.”….Read more>>
