Re: Phone charges 2x faster in airplane mode.
I leave the GPS on all the time in High Accuracy mode. I have not found that to effect the battery life at all. The only time it is ever used is when an app calls the GPS to get a location update. IMO, you don't need a macro to turn GPS on for your MapMyRun app. Just leave it on all the time. Problem fixed.

Don't know about other folks, but with my phone, by the time I can get my fingers off the Swipe to Unlock and click to open an app, the 4g/3g data path is already up and rarin' to go.
I have NOT ever found any negative issues with turning the Internet OFF when the screen is locked.
What I have noticed, and it was my prime reason for doing so, is that the battery usage while the screen is locked, and the Internet OFF, is something under 0.5 percent/hour.
I don't use chat modes, have no use for anything that wants to notify me that the neighbor next door is giving away their cat.
Blue Mail has updated the message headers about 2 seconds after the screen is unlocked, so waiting on my email has never been an issue. I have email configured to only download the title and the first line of text, so it is fast as greased lightning.
The internet is not required for normal telco and text usage, so why leave it on?
