1. No
2. Yes

 

It may take some time for the changes to take effect. Try rebooting the phone if you cant wait.

I dont notice any difference in terms of battery life w/ or w/o the app.

 

I found that Lightflow drained a lot of my battery when I had it installed. After I uninstalled it, my battery life increased dramatically. But then again, I had a lot of notify LEDs on. Like probably 10-15 apps.

 

i fond its easier on battery,, for the simple fact im not having to swipe my phone open to see if anything is going on,, walk by,, its flashing i open,, if its not i dont open,,,

with out LED notification was swiping steady,, one of the main reasons i took the SG2 back

 

Excellent point. I do the same, but I never really thought about it having a positive effect on battery life until your post.

 

there is a timeout setting. i find this to save some battery that the app takes away

 

This only needs to be checked if you find the app keeps stopping working. It shouldn't make any difference to battery.

Run in foreground just stops android from killing a process unless it "really" has to. Usually used for things like music players to stop your music getting interrupted if running low on resources.

Personally I've never needed to have it set on any of my phones, but some people can't run without it being set.

By the way, if you hadn't guessed, I'm the author of the app

 

You may find the newer versions better. A few revisions back I rewrote some areas of the app that got accessed frequently and cut the running time of them by up to 75%.

The latest release has also added a new notification method which just displays the most recent notification to have come in. This makes it the most battery efficient method (albeit without successive notification cycling) as it doesn't need to use any repeating wake alarms (code alarms, not the type to wake you up) to change the notification cycle.
