Battery life is probably the biggest problem with Android based phones. Frankly, it is not possible to use one's phone meagerly because smartphones come with a lot of promises and softwares. The applications are irresistible to use and by the end of the day, only if you are lucky enough, you will have enough charge left to make one final phone call.
The problem basically arises due to the battery voltage. For most of the phones, the standard batteries are the ones with 3.7-volt which, in reality, has no chance of lasting long because of numerous applications running on the background.
However, thankfully there are a few ways you can save a little bit of energy on your battery everyday which can be met by reducing the time-to-time energy loss.
Wi-fi: Always remember to turn off your wi-fi when you are not using it. The energy loss to wi-fi works in the same way as that of the power loss to Bluetooth. Of course, you will need the wi-fi when you are coordinating with your office, but otherwise keep the wi-fi usage down. The Android users also have the option of adding the wi-fi toggle widget to their home screen to make the process easier.
Applications: Shut down any unused app on your smartphone as every app consumes a bit of your phone's power and by cutting the drainage you can actually reduce the processor workload. An app, Advanced Task Killer, can be installed on your phone which automatically shuts down the apps which are not in use.
Power saver mode: A power saver mode is now included with most of the new Android phones, which helps you manage the phone's power consumption. The app has the ability of reducing screen time-outs, turning off vibration, dimming your screen and disabling home-screen animations which are the major contributors to power drainage.
Juice Defender: The Juice Defender is another app which reduces your workload of manually adjusting all the systems on your phone which may consume power. This app, however, manages your radio system and optimizes your battery life on a time-to-time basis.
GPS: Finally, turn off the GPS when not in use. You may use it to find the nearby restaurants and ATMs but try to go easy on it. The signals sent and received by the GPS systems consume more battery life. Certain apps may also ask your permission to use the GPS system, and when you are not sure, remember to say no.
