While many of us now use mobile phones instead of land-line phones in our homes, these mobile phones come with lithium batteries which require some maintenance as long as they are used. Once you know how, you can optimize your phone’s battery life fairly easily.
- Turn the phone off. Only do this if it’s going to be for several hours; turning a phone on/off actually uses a massive amount of power itself. This will probably be the most effective and simple way of conserving your battery’s power. Why? This will help conserve energy and also charge your phone. If you don’t plan on answering the phone while you’re sleeping or after business hours, just turn it off. Do the same if you are in an area with no reception (such as a subway or remote area, since constantly searching for service depletes the battery fairly quickly).
Some phones have an automatic power save feature, but it takes about 30 minutes with no service to kick in. By then, much battery power has been used. If you are using a smartphone and have no reception, disable the phone functionality (flight/airplane mode).
