How do i quit a game to save battery power?

Lately, my cell phone battery barely lasts a day (used to be 'round three days based on light browsing and only a few calls a day).

After I test my apps, I always turn off my phone but when I use it again (an hour later) the battery which might have been 66% is not down to 22% (example values to make a point).

I have looked at some of the options but didn't find anything which would help me kill the app once I no longer want to use it.

I bet there is a simple solution but Mr. Google doesn't play nice today

Do u just press the home button or do u exit with a button?

If u have not added an exit button, make a button for exit and

Exit button-on clicked=> browser-close.

There is a close action in the browser plugin actions which you can use.

Moreover try using chrome with ur games instead of default browser.

Try using Advance Task Killer from store
