Smartphones today are just like power hungry monsters. No matter how bigger battery they have, how long the smartphone will perform between charges depends largely on the user’s device usage pattern. Calling, messaging, gaming, multimedia – there are many utilities that a smartphone today offers and more we use those, the lesser battery backup we get.
There are plenty of softwares available today that promise to enhance the battery backup of your device. These softwares actually help save some power that gets wasted due to amateurish use of devices.
But, without these softwares also, one can get maximum out of their smartphone battery without cutting down on tasks such as calling, messaging, internet usage or even gaming.
Optimise Display brightness
The display of a smartphone alone uses a major chunk of the battery power. But, we can optimise the display to consume just the right amount of power and thereby increasing efficiency too.
All smartphones today come with ambient light Sensors but by default the system is set on a comfortable brightness (sometimes max brightness too) setting that allows the display to be visible in both bright and low light conditions. So, if your device is not using the ambient light sensor it is unnecessarily wasting energy. The ambient light sensor controls the screen brightness according to the ambient light thereby conserving power wherever possible.
Say no to live wall papers
Live wallpapers, as we all know, are really cool with all this jazzy effects and transition. But to do all that they use the processing power of the smartphone and thereby consuming battery power even when sitting idle.
Processors are optimised to go on a low power mode as soon as activity level goes low in order to conserve battery but live wallpapers restrict it from getting in a low power mode.
Set a shorter screen timeout
Screen timeout time is the time taken by a display to go to the standby from an active mode. This mode allows the display to save power when the display is not required by turning it off.
By default, many devices are set on a two minute timeout which means the display will go to sleep mode after 2 minutes and if you do not need the display to be on for that much time without any activity turn it down to 15 seconds or 30 seconds to save your phone’s battery power.
Timely sync
Devices today are connected to the internet 24 x 7 and due to that manufacturers have come up with synchronisation services online that keep a safe and secure backup of your device.
But, the service manufacturers also set the device to sync data with the online accounts whenever there is a change or addition to the files on device.
If you are not a very heavy user you can reduce the number of times your device synchronises itself with the account. This way the device will drastically reduce the online activity that otherwise continues in the background and consumes power too.
Turn of radios if not required
Bluetooth , WiFi, GPRS – all such radios or wireless connectivity protocols come at No 2 position when it comes to power consumption after the display. Usually, people forget to turn off the Bluetooth radio once the work is done. Same is the case with the WiFi radio which draws a lot of power from the battery to stay operational without the need to do so.
So be smart and remember to turn off the radio similarly you turn off your car’s ignition after you reach your destination.
GPS is for outdoors only
Global Positioning System is a unique technology that allows the device to be aware of its location by getting data directly from the geo stationary satellites way above in the sky. But do you know that GPS only works when you have a clear line of sight for the sky?
Many applications such as your camera App too utilises GPS to tag the location of the photograph and many times such apps continue to run in the background while utilising GPS as well.
Always, keep a check on what all services are running on your device and especially the GPS if you are indoors when it won’t do any good to you other than feasting upon the battery power.
Use the task manager often
Today as the devices are getting faster, the operating systems are also changing. Today operating systems do not kill the applications automatically as soon as you exit from it or move your focus to another application.
Rather, all the applications keep running in the background although in a low power state, utilizing both processing power and memory that leads to a lower battery life. If you do not need an application, kill the application from the task manager. This way the background activity will be reduced and also the device will perform faster.
And Finally Vibrate less
Vibration mode is today available on all smartphones but do we actually know why was it invented? Well, the vibrate mode was invented to alert the user when the device is in his pocket or bag but today most people use it regardless. Vibrators use much more battery power than the normal ringer does. So, if you can do without it, it’s good for you.
Even touchscreen devices today provide haptic feedback to make the touch feel more realistic. But as said earlier that too uses battery, so if you can do away with the feedback it will help you save some more battery. This is especially useful for those who do a lot of texting.
The second most important improvement in this application is the inclusion of book sharing option which allows fellow Peek users to share created books with others from within the application. 
Evernote can also search for a text within images including snapshot of business card, magazine articles or even whiteboard. The free storage limit of 60 
Most of the Android handsets, working on Android version earlier than 2.3 Gingerbread, will find this app handy, whereas those with the latest version of Android will not need this app since the phone resources are much better managed on the latest version.
The app helps the users turn their phone screen into an elementary keyboard, so if they write the letter ‘w’ on their phone screen using their finger, all the contacts starting with the letter ‘w’ begin to appear on the screen, along with music tracks. If the users write more letters on their screen, the search becomes better and narrower so there is more likelihood of getting what they want. 
Android users can search the Android Market for third party apps such as ‘Readingo’ which allows them to use Instapaper on their Android phones. The Pro version of Instapaper allows users to tilt the screen and scroll down the page without touching the screen. The tilt screen feature can be turned off and on according to users’ convenience.
