So to ensure that your phone is using as little battery as possible, you’re best off always pressing the Home button before locking so that no app remains running.
To turn your phone completely off, press the Sleep/Wake button for a few seconds then drag the red slider that appears. The two situation that I usually do this is when I’m almost out of battery and when my phone is acting kind of wonky.
I run my wireless security under a WPA Pre-Shared Key, without broadcasting my SSID.
Granted, I’m the only person on my block who runs wireless (yeah, I checked), but I like being secure.
Along somewhat similar lines, a handy way of saving a tap when you need to type a capital letter is to touch the Shift key then slide over to the desired key. Do you need to type an umlauted-u (ü) but you’re not using the German keyboard?The i Phone, like the Mac, is extremely simple and intuitive to use.Odds are that you’ve never even cracked open the user manual since the way just about everything works is pretty obvious. there are many small “convenience features” that are often hidden away.For instance a relaxation app is able to continue playing sound but save battery power with the screen off.So, locking your phone is actually more like “display sleep” on your Mac (⌃⇧⏏ or Control-Shift-Eject for those of you who can’t read Macroglyphics).
You’d be surprised to know how many people don’t know how to turn their phone completely off.
