A recent study performed by KS Mobile, makers of the Battery Doctor app, found camera app Camera360 Ultimate as the top battery sucking Android app. Other popular battery sucking apps in the list are Microsoft's Outlook and the addictive game Candy Crush Saga.

KS Mobile tested which Android apps trigger a warning to smartphone users about their own battery consumption levels with the highest frequency. Camera360 Ultimate app which has nearly 180 million users world wide was the top app in the list. In second place was Microsoft's Outlook.com app. The app which has "8 different color themes to personalize your experience," is the reason for your phone's low battery.

KS Mobile says that users should practice "smart battery preservation." The reports suggest users should disable automatic time zones and clock updates; reducing the frequency of push notifications and turn the GPS off when not required. The report also says that users should charge their smartphone through a power outlet instead of a USB port.
