Late yesterday I was chatting with a local friend about iPhone usage and battery life and some other apple tech things. Did you know you should occasionally check your iPhone's usage to see if the ratio of usage to standby is healthy? Yes you should.
Go to your settings->general->usage and then scroll down to battery life and you'll see the usage/standby ratio. If the numbers are 50/50 you have a problem that needs fixing. It is also why you probably have a battery that runs down faster than it should.
Unfortunately my usage is 50/50 and I have to go through a restore today. When it gets to this point, there is probably software corruption that will rear its ugly head one of these days.
And, you can keep this from happening by doing one simple thing that no one ever tells you: Turn your phone off once a day. Power off completely. This gives the phone time to get rid of the fuzzy bits and recover. If you do not do this, it's like leaving your car idling all night. You might not be driving, but the motor is still running and not in a good way.
The good thing is you don't have to leave it off all night long, according to an Apple genius person, just powering off completely before you put it on the charger is all you need. Yes, the phone will power up when the charger goes on, but just being off that short a time is what the phone needs.
And really, do I really need my phone as a bedroom clock? No. Turn off the phone or you'll be looking at a painful restore like I will do today and my daughter had to do yesterday.
Updated: I think I found the real reason my phone usage and standby times were the same, it was because of my Moves app which is working in the background all the time. Once I turned that off, the two times separated as they should.
