Smartphones have come a long way in terms of design, camera, or even processing power. However, we have not seen much breakthroughs when it comes to battery technology.That said, here we have listed out some lesser known tricks that will help you get the most out of your smartphone battery:1. Turn off vibration and haptic feedbackWe like the mild vibrations while typing on the smartphone keyboard. But they absorb a good amount of battery because we spend a lot of time on typing throughout the day.Besides, if you don\u2019t need to get notified by vibration, then turn the `haptic feedback\u2019 off as it actually takes more battery power to vibrate your phone than it does to ring it.2. Go for Black coloured wallpapersIf your smartphone boasts an AMOLED display, then applying black coloured wallpapers will help you save battery life. This is because pixels that make the AMOLED displays only utilize battery power to illuminate light colours and don\u2019t need any energy to show black colour. Simply put, the more dark or black pixels you have on your AMOLED display, the less power it consumes to illuminate them, thus saving the battery.3. Don\u2019t miss on Android updatesUpdating apps might seem to be a cumbersome task, but it actually helps in improving the overall smartphone performance and battery life. This is because developers keep updating apps to improve on battery and memory optimisation. So make sure your smartphone has the latest version of apps installed.4. Turn on airplane modeThis is not an everyday solution, but can help you cut battery usage. Turning on airplane mode will cut you from the outside world, but will allow your smart phone to last longer for multimedia apps such as videos, music player or games that don\u2019t need any connectivity.It can do wonders if you are travelling in a poor network zone where your smartphone antennas consume a lot of power to register on the available networks. Simply turn on the airplane mode if you don\u2019t want to receive any calls, messages or use the internet.5. Remove on-screen widgetsAndroid operating system is all about widgets that offer tons of information on your smartphone displays. It is a good thing to have everything on screen; however, it plays havoc on your smartphone battery. Delete the widgets that are placed to offer information not required throughout the day and still fetch data from internet such as weather apps etc.6. Turn off auto-syncApps such as Gmail, Twitter, calendar, constantly refresh themselves to offer the latest information. This is required if you just cannot afford to miss important information, but also takes a toll on battery life.Go to Settings > Google account and turn off auto-sync for apps you don\u2019t need constantly updated.7. Check GPS, Bluetooth, NFCAlso, don\u2019t forget to check on Bluetooth, GPS, Wi-Fi, NFC and mobile data if you are not using them. Switch off the Wi-Fi if you are connected on mobile data and vice versa. The NFC feature may get turned on if you restart your NFC-enabled handset, so keep a check on this too.
