Basics of Your Samsung Galaxy Note 3’s Battery

By Dan Gookin

Perhaps the most important item you can monitor and maintain on your Samsung Galaxy Note 3 is its battery. The battery supplies the necessary electrical juice by which the phone operates. Without battery power, your phone is about as useful as a tin-can-and-a-string for communications. Keep an eye on the battery.

How to monitor the Samsung Galaxy Note 3’s battery

Your phone’s current battery status is displayed at the top of the screen, in the status area, next to the time. Here are the icons used to display the battery status.


  • Heed those low-battery warnings! The phone sounds a notification whenever the battery power gets low. The phone sounds another notification when the battery gets very low.

  • When the battery is too low, the phone shuts itself off.

  • The best way to deal with a low battery is to connect the phone to a power source: Either plug the phone into a wall socket or connect the phone to a computer by using a USB cable. The phone charges itself immediately; plus, you can use the phone while it’s charging.

  • The phone charges more efficiently when it’s plugged into a wall socket rather than a computer.

  • You don’t have to fully charge the phone to use it. If you have only 20 minutes to charge and the power level returns to only 70 percent, that’s great. Well, it’s not great, but it’s far better than a 20 percent battery level.

  • Battery percentage values are best-guess estimates. Just because you talked for two hours and the battery shows 50 percent doesn’t mean that you’re guaranteed two more hours of talking. Odds are good that you have much less than two hours. In fact, as the percentage value gets low, the battery appears to drain faster.

How to determine what is drawing power on the Samsung Galaxy Note 3

A nifty screen on your phone reviews which activities have been consuming power when the phone is operating from its battery.

To get to this screen, follow these steps:

  1. Open the Settings app.

  2. Touch the General tab.

  3. Choose Battery.

Touch an item in the list to view specific details. For some items, such as Screen, the details screen contains a button that lets you adjust the setting.

The number and variety of items listed on the battery-use screen depend on what you’ve been doing with your phone between charges and how many different programs are active.


How to use the Samsung Galaxy Note 3’s Power Saving mode

The Galaxy Note comes with a handy power-saving feature that you can employ to help squeeze extra juice out of the battery. To use these power-saving tools, follow these steps:

  1. Open the Settings app.

  2. Touch the General tab.

  3. Slide the master control by the item Power Saving Mode to the On position.

    If the master control is already green, you’re good to go.

  4. Choose the Power Saving Mode item.

  5. Ensure that all items on the Power Saving Mode screen are checked.

    Power saving is enabled.

The power-saving feature automatically disables certain phone features — specifically, power-draining features. It also throttles the screen brightness.

Choose the item Learn About Power Saving on the Power Saving Mode screen to review some tips and tricks for extending battery life.

How to extend the Samsung Galaxy Note 3’s battery life

Here’s a smattering of things you can do to help prolong the battery life in your Galaxy Note:

Turn off vibration options. The phone’s vibration is caused by a teensy motor. Though you don’t see much battery savings by disabling the vibration options, it’s better than no savings. To turn off vibration, follow these steps:

  1. Open the Settings app.

  2. Tap the Device tab.

  3. Choose Sound.

  4. Choose Vibration Intensity.

  5. Throttle each setting down to the lowest possible position.

    Or you can slide the control all the way over to the left, which disables vibration for each item.

Additionally, consider lowering the volume of notifications by choosing the Volume option. This option also saves a modicum of battery life.

Dim the screen. The display is capable of drawing down quite a lot of battery power. Though a dim screen can be more difficult to see, especially outdoors, it definitely saves on battery life.

Turn off Bluetooth. When you’re not using Bluetooth, turn it off. Or, when you really need that cyborg Bluetooth ear-thing, try to keep your phone plugged in.

Turn off Wi-Fi. Wi-Fi networking on the phone keeps you on the Internet at top speeds but drains the battery as it’s being used.
