10 tips for better battery life for Android phones

Summary: Battery life on Android phones is better than it used to be but it can still sometimes be a chore to get through a busy day with juice left in the tank. These tips will go a long way to get you safely back to the charger.

  • Keep your phone cool

    It's not common knowledge but some folks in the know ensure me that letting the phone get too hot can impact the battery life. I'm told the impact on the battery is particularly noticeable at 95 degrees and above so if you live in a hot climate as I do you'd better keep the phone out of the heat.

    If it's very hot outside you don't want to be walking in the heat with your phone in hand, as that exposes it directly to the heat. Keep the phone in a bag or a pocket as much as possible to keep the battery from taking a hit.

    If you go to a hot place like the beach, don't leave your phone sitting out in the sun as that will surely suck life out of the battery.

  • Turn down the screen brightness

    This is obvious but worth mentioning. The display on Android phones is the biggest drain of battery, so it makes sense to turn it down as low as possible. This can add hours of life to the battery.

    Android phones have an auto-brightness setting that automatically adjusts the screen brightness based on ambient room light. This normally works fine but when trying to sqeeze the most up-time on a charge it is worth turning off. Then you set the brightness manually to the lowest setting that is comfortable to still see the screen. It's worth repeating that this can add hours of battery life on a given day.

  • Reduce screen timeout

    Android phones will automatically dim and then turn off the display after a set interval. It's worth setting this interval as short as possible which will have a good impact on battery life.

    Some Samsung Galaxy phones, like my Note 2, have another setting called Smart stay. This prevents the screen from dimming and timing out if it detects the user is looking at the screen. This is a great utility and makes it possible to set the timeout interval shown above to as short as possible. The screen won't keep turning off while you're using the phone, but will do so if you're not using it after a few seconds.

  • Slide Show!

    Can we please get rid of this format. Its possible for me to enjoy reading an article in this format. Information is good, format is bad. bad. bad.
    • Exactly

      I started to read the article but then saw the format and thought "No Way!"

      ZDnet's method of reloading the full page with each new picture, it is horrid.
      • Agreed

        Stopped reading as soon as I saw it. I guess James still gets the click credit.
    • Completely agree, But i've found a way around it

      Save the article to pocket, and it will have all of it on one page. It's an extra step that shouldn't be there, but it works.
      • too much work

        I'd rather just not read the stupid article.
    • Slide Show

      As mentioned by so many before, I do not go past the first page. Certainly you are not doing your advertisers any good when we don't bother to go past the first page. Annoying and wasteful will cover for my opinion.
    • Android Market

      Download any kind of PRO APPS or Paid Apps or Games from Android Market free

  • Page reload

    Exactly! How about loading the whole article at once. I bet that would save some power!
  • format

    I was going to send the link to our company android users but agree that the constant paging is frustrating.

  • Use an app

    I tried a few different battery apps, but 'battery doctor' (KS Mobile Inc) stood out with all / most of the above tweaks done via schedules. I can now go for 2.5 days on a single charge with no change in the way I use the mobile.

    I have nothing to do with the company, just a happy user.
  • Third-party apps help

    I use a third-party app that turns off the radios when the phone goes to sleep. It takes only a few seconds for them to come back up when I unlock the phone. Also, the app puts the phone in Airplane mode at night when I'm asleep. My testing with and without the app showed an almost doubling of battery time with the app. There are several apps that do this, but I use 2X Battery.
  • Hate Zdnet Slide Shows

    I think people were making better slide shows back in the 90's. At a minimum stop the full page refreshes. This is where you put loading a new page so you can load new ads at the expense of having a useful slide show.
  • Every time ...

    ... the feedback requests that you put the whole article on one page. You are simply going to frustrate us all. Please change the format for all future postings. I bet 95% don't read on once they see it is on a zillion reloads.

    The content has been useful but presentation totally unhelpful.

    BTW pls ignore trx_1 and get rid of the slide show TOTALLY
    • We all seeem to agree

      ... yet this format continues to be used. I, like many others just don't read the articles in this format any more. You get my attention with the title, but it is not enough to keep me scrolling from one photo to another. Get a clue and change with your customers comments.
      • yep

        I'm not reading either. If they insist on a full page refresh rather than just making the picture and text dynamic, I'm skipping the article.
        The editor probably tried in on the internal network and thought, it works, it's fine......
  • My Phone lasts all day

    I can use my phone all day and still have battery life left when I am at home without it hitting a charger. And If I need a little extra juice for a late night, I charge it when in for about 30 min or in the car heading to my destination and I am good the rest of the evening.

    Nokia Lumia 920 with Windows Phone 8; It just works.
    • Troll

      Did you do side by side comparison? My Nokia Symbian phone from 10 years ago could go for a 3+ days. Same with my Sony Ericsson from 7 years ago. So what?
      • Basically if you don't use the phones

        the battery will last forever.
        Start playing games or listening to the radio, and it is another story.

        Of course at work I can always plug into a USB port.
      • Ditto With Motorola 1100

        having said that, isn't this rabbit trail comparing apples to oranges (feature phone vs smart phone)?
