Your mobile phone, like any other device, performs best if you take proper care of it. Like any computer, it's a good idea to restart it on a regular basis. If you don't know what I mean, it's simple. Turn it off & back on. I do this every day. Most people's biggest complaint, regardless of brand, is insufficient battery life. There are things you can do to affect this. Your phone will hold a charge longer if you clear your apps regularly. simply push the home button twice. Your open apps will appear. Sweep them off the screen one by one. Many carriers have done away with contracts. That means they no longer subsidize your device purchase, so you now pay full price. To protect your investment, as much as $800 in some cases, here are some recommendations from lifehacker,com. Don't expose your phone to high heat. It can permanently damage the battery. Don't run the battery all the way down. That reduces its capacity to hold a charge. If you're not going to use it for several days, turn it off & store it in a cool dry place, with about a 50% charge. Bottom line? Take care of it & it'll take care of you.
