Battery drains much faster

[Rupesh Mehta 1]

I am using my micromax canvas 2 phone since 1.5 years without having issue, but since last week my battery drains much faster than usual. Drains 20% in 8 hours in stand by and even with mobile data off. On checking the battery from settings Mobile Neetwork signal bar shows gray instead of green which might indicate a week network signal...
so, will you please suggest me any application that could short out this issue?

You're correct--weak cell signal can eat up battery. There isn't any app that can help that--you either need to change your wireless provider, or consider turning Airplane Mode on when you're in areas of poor signal.
