Scotty Loveless, a former Apple Genius, has posted the best guide we’ve seen to solving iOS battery drain. Unlike many guides that tell you to turn off every feature, Loveless offers a more targeted approach, including instructions on how to test battery drain and specific suggestions that are likely to improve battery life. Two surprises: the Facebook app is a huge battery hog and quitting apps may hurt battery life. follow link
iMovie '09: Speed Clips up to 2,000%
iMovie '09 brings back the capability to speed up or slow down clips, which went missing in iMovie '08. Select a clip and bring up the Clip Inspector by double-clicking the clip, clicking the Inspector button on the toolbar, or pressing the I key. Just as with its last appearance in iMovie HD 6, you can move a slider to make the video play back slower or faster (indicated by a turtle or hare icon).
You can also enter a value into the text field to the right of the slider, and this is where things get interesting. You're not limited to the tick mark values on the slider, so you can set the speed to be 118% of normal if you want. The field below that tells you the clip's changed duration.
But you can also exceed the boundaries of the speed slider. Enter any number between 5% and 2000%, then click Done.
The Ultimate Guide to iPhone Battery Drain
I could see that my wife's iPhone 4S was never sleeping (Usage and Standby times were equal). GREAT! I finally had a diagnosis of the problem.
How come this advice is not better known?
But, Apple offers no insight nor tools to help fix this.
Force quit every app - nope. Restarts - nope. Upgrade to iOS 7 - nope. More Restarts - nope. Turn off Location Services - nope. Turn off Background App Refresh - nope. More force quits - nope. Install Battery Performance Monitor apps - nope.
So now what?
Installing System Activity Monitor app helped, but the savings finally came from deleting an old Mail account which obviously was caught in a loop.
Surely Apple could give tools to identify issues like this earlier?
