I only find myself turning it back on when it hits 20% and when it's charging.
I only use to see what I'm at when I'm under 20%. While I'm aware it's red at that point, there's times I need to know how much I have left.
EDIT*
I'm not the only one.
When I used to keep it on, I would obsess and worry about the battery life and how much was left. One I turned it off, I no longer seem to care about the battery until I get a low battery warning. This system works better for me and now the battery percentage is off on all my devices.
Also, TWO2SEVEN: I added a vote to your poll since I seemed to have forgotten when I actually commented in your thread.
This is how i resolved my battery issue.
I turned off the % sign and now just enjoy using my iPhone as it was meant to be.
Yes or no? What is your opinion?
I find that if I have the % in the top bar I obsess over how much is left. So after a week with the phone I turned it off. We'll see if I worry about battery as much now.
