Having to charge your phone or tablet device more frequently lately? Sometimes a reduction in battery life can happen when there is an upgrade to your device’s operating system. But certain apps are known to drain batteries too, and some simple changes to your settings may do wonders for improving your phone's battery life. One of the biggest drains on your battery is when the screen is on brightly.


At this point, this column will split into two parts. The first part is for iPhones/iPads (by Wendy Wright) and the second part is for Android-based phones and tablets (by Suzanne Logan).

There are many types of Android phones. These instructions may not match the type and version of your phone, but this should get you close to a solution on your phone.


Let’s first look at that bright screen issue mentioned previously. You can reduce the brightness whenever you can, or let the phone automatically adjust for you.


1. Pull down from the top of the screen.

2. Move the brightness bar to the left as far as you want.

3. For automatic adjustment, go to Settings>Display>Adaptive Brightness “ON”


Another good setting is to put the background into “Dark” mode:


1. Under “Settings”, go to Display. Tap the Advanced drop-down menu at the bottom of the page if needed.

2. Tap Device Theme, then tap “Dark” in the dialog box.

3. There may be a “Dark theme” listing under Settings>Display.


Also in the Display area of Settings, you will find the “Screen Time-out” option. Set it very low, like 30 seconds. This will turn off the screen when you are not using it.


Using “Live Wallpapers” will also increase the battery use for the background. Turn these off also.


1. In Settings>Display>Styles & wallpapers

2. Choose “none” or a solid color. Just make sure the title doesn’t include the word “living” or “live.”


To see what Apps are using the most battery: Under Settings>Battery find the “Battery Usage” option. It may be in the upper right three-dots. This will tell you how your phone is using the battery by percentages. You can restrict Apps that use a lot of battery by tapping on the App here (Battery>Battery usage>App) and tap on “Background restriction”.


There may be an Adaptive Battery setting under Settings>Battery> Adaptive Battery. Make sure that this is “on.”


Be sure to turn OFF tethering and hotspots when you are not using them. For instance, turn OFF your WiFi when you leave home. (Pull down from the top of the screen and touch the WiFi icon OFF.) Only turn it on when you want to use the WiFi at your destination (like at the library). Also set the WiFi to NOT turn on automatically near saved networks:


1. Settings>Network & internet>Hotspot & tethering OFF

2. Settings>Network & internet>WiFi>WiFi preferences Turn on WiFi automatically - OFF

3. Settings>Network & internet>WiFi>WiFi preferences Connect to open networks - OFF

4. Settings>Network & internet>WiFi>WiFi preferences Open network notification - OFF


Be sure to uninstall any apps that you don’t use anymore.
