Help ace going to sleep with app in foreground - battery usage.

[chrcol]

If I put the phone in sleep either by the power button or leaving it idle with something like go sms pro running, does it use up more battery like that then leaving it on the home page first?

So say if eg. I leave it on a page showing sms messages and it then goes to sleep so when the phone is unlocked again that app is still running.

Battery is one of the major issues in SGA.
Working apps consume ram, ram takes up battery, so whenever you leave any app running either on the main screen or in the background, it will consume more battery. Unless required, you should close all unnecessary apps before you put your phone to sleep mode. It'll prevent unnecessary battery consumption.

For your case, I am not sure if go sms keeps running in the background or shuts down by itself, but if it is working it will consume more battery, however small that may be, but it will. Just use the back button to close the app when you exit.
Use the task manager to check what apps are working in the background. Then you can close all the unnecessary ones.
