Smartphone can serve as your MP3 player, digital camera, gaming system, and even your TV while you're out as long as you have battery power. If it seems like smarter phones are getting less life out of their batteries... you're absolutely right. Smartphones can help you get a lot done while traveling, but if you're doing a lot in a day, you're apt to see your screen go dark long before the sun goes down. Following few small things during your day can help extend battery life:-
Mixed signals
It takes extra power for your smartphone to search for a data connection. If you're somewhere where you won't get a signal, like an airplane or subway, putting your phone in airplane mode or turning it off altogether will prevent it from draining your battery. Turning your phone on does require a bit of extra power, so it's best to save by shutting it off.
Likewise, turn off wifi when you don't need it. When it's active, your phone scans for available wifi connections constantly, which kills battery life.
Battery bleeds faster when you're inattentive.
Focus on the task at hand
You can have your email open, search for directions to a local restaurant, watch a video on YouTube, and play games at the same time — but chances are you're really only focused on one of those tasks. Everything you have opened on your phone is using some amount of battery power. Try to focus on doing just one thing at a time on your phone, and close unnecessary applications to keep them from draining your battery.
Things like your GPS and the bluetooth connection you use to connect to your hands-free device gobble up a ton of battery power.
It takes more battery power for your phone to vibrate than it does to ring. While you absolutely want to have your phone on vibrate (or turned off) when you're at a movie or in a meeting, keeping your ringer on at other times can help extend battery life.
Brightness
Bright screens look great but are a huge drain on your phone's battery. To stretch your phone's life, go into the controls or settings and dim the backlight or brightness of your screen. While the dimmest setting might be difficult to read (especially if you're somewhere brightly lit), something toward the middle will extend your battery life without putting too much strain on your eyes. If your phone has an auto-brightness option, using that can be a one-step solution. Also try to avoid using animated backgrounds on your phone.
Mandatory power off
Just as you would with a toddler, the easiest way to make sure your smartphone's battery lasts all night is to give it a nap at some point during the day. If you're headed into a meeting for a few hours, turn off your phone and leave it in your desk.
Still having trouble?
If you still find yourself running out of battery life before the end of the day, plug in for charging or use an external battery pack.
