Question: It’s a hassle when the battery in my phone or tablet gets low at inconvenient times. What can I do to help a battery last longer between charges?
Answer: One simple thing you can do to extend the battery life of your phone or tablet is to turn down the brightness of the screen to at least half.
This can usually be found in the Options or Settings area.
On an Android device, such as a Samsung Galaxy, swipe down twice from the top of your screen. You’ll see a sun icon at the bottom, on the left of a thin bar. Manually lower the brightness of your phone or tablet by dragging your finger along this line.
Keep in mind that Android settings vary across devices, so the steps you see here may look a little different on your phone.
On an iPhone or iPad, swipe down from the top right corner of your display — or on iPhone 8 or earlier, swipe up from the bottom edge of your display — to access the Control Center, which has a thick brightness bar identified with a sun icon. To lower the brightness, use your finger to drag the line between light and dark down or to the left, depending on your phone’s orientation.
