You could have the most powerful smartphone around, but that amounts to naught if it dies out on you every few hours. Karan Bajaj offers a few simple tips and apps and to maximise your phone's battery
Generic Tips 1
Screen Brightness
Although most phones come with a light sensor that is used to automatically adjust brightness of the display, you need to manually set the brightness as low as possible. The automatic setting constantly alters the brightness and that leads to higher consumption. 2
Wireless Connectivity
Functions such as EDGE, 3G, Wi-Fi, Bluetooth and GPS are important to phone usage, but they are the biggest battery hogs as well. You can increase your battery life by switching off functions that you don't need. Even switching from 3G to 2G helps . 3
Push Notifications
If push notifications are turned on, your phone constantly pings various services to check for updates. Therefore, data connectivity or Wi-Fi is constantly being used to check for updates. Some devices even play a sound and display a notification on the screen. The number of different notifications you leave on will have a direct impact on the phone's battery life. 4 Background Tasks
By default, pressing the home button does not exit apps, it just moves them to the background — this helps with quicker multitasking on a smartphone. Problem is, even background apps consume hardware resources (except on iOS where the apps are completely suspended). Use a task manager to exit apps completely and give a boost to battery life. 5 Haptic Feedback
Many touchscreen phones offer haptic feedback — a slight vibration while typing, pressing an on-screen button or in some phones, every time the screen registers a touch. Check if you can turn this feature off or control when the vibration occurs. You can also choose to turn off the vibrate notification for calls/SMS when the ringer is on. Apps to Enhance Battery Life BB

Battery Cases
Cases like Mophie's Juice Pack ( 3,000 onwards) have a builtin battery — the case connects with the charging port on the phone and keeps the internal battery topped up.
Portable Chargers
These handy gadgets usually come with different charger pins and are priced at 3,000 onwards. Most of them are good enough to provide two full charges to a phone.
Spare Batteries
Manufacturers provide replacement batteries — either the same or larger capacity than the original. Get a spare battery and keep it charged as a reserve. iPhone Specific Tips
Location Services
Some apps use location services to deliver relevant content and services. This could be via GPS, Wi-Fi or cell tower location, thus affecting battery life. Go to Settings and disable apps that don't need it.
Siri
The iPhone 4S's voice assistant Siri comes on when you raise the phone to your ear. Switch off this 'raise-to-speak' function from the Settings — it keeps the phone's proximity sensor in an always on state — thus consuming more battery. Android Specific Tips
Check Battery Usage
Go to Settings > Applications, tap on Battery Use and find out what is consuming the most battery on your device. You can then close or uninstall the apps that you don't use too often and figure out how to better utilise battery life.
Home Screen
Android has always offered live wallpaper as well as various third-party animated widgets. There's no denying that some effects make the phone look pretty, but they also make the processor work overtime
