If one of these apps with location turned on is in the bottom when you double click that means it is still alive and pinging home. All of that can waist a battery on an iPhone.

I could do this, but the ability for the phone to identify your location is useful for certain apps. Besides, I'm not sure why this would all of a sudden become an issue when the settings have not changed.

Take it to the Genius Bar Ed. They can give you a new one right there. I've had battery problems with every iPod I've owned and they swapped them with no hesitation.

I decided that's what I'm going to do tomorrow. Only potential problem is if they do give me a new phone, I'm hosed because of my aforementioned issue (inability to synch).

Generally speaking, most apps and phone hardware won't suck up that much juice. Even GPS in high accuracy mode will run for days without killing the battery. The biggest drain is always the cell radio, and it always sucks more juice the farther away from a tower it gets.

So, if you're in an area with spotty coverage and running apps that constantly use data, the battery life will go down considerably.

Li-on batteries don't really have memory issues, but they do have a charge cycle life. If you've run your battery completely dead several hundred times, it could be getting close to worn out.

That's what I figured regarding apps and their ability to drain a battery. Unless my iPod was constantly running at full volume, I wouldn't expect it to discharge this quickly.
I think I may have completely discharged a battery once or twice, but 99.9% of the time, it still usually has at least 75-80% battery life left before I plug it in at night.
I just moved to an area of spotty coverage, but I've been here a month and it hasn't been an issue until yesterday.

I have a cover. Same one since I purchased the phone and I've never had an issue until yesterday.

The what? The logic board and processor use the chassis as one big heat sink.

LOL. Guess I can exclude that as a source then;)

In technical terms, there is a hole on the right edge of my phone that shoots out hot air.

That would be quite a trick considering there's nothing in the phone that can move air, nor really any space for air to move around. All the internal heat gets dumped into the SS frame.

Holes in the phone are as follows: Headphone jack, noise cancelling mic, speaker, dock connector, main mic, and the earpiece on the face. There's no "heat hole".

There's also the SIM slot on the craptastic AT&T version.

I was referring to that small hole on the sim slot. Not sure of its function but I noticed it releases warm air and the phone overheated when I had it covered. I was speaking objectively.

Isn't that where you insert a pin to remove the card?

Yes. Covering the sim slot will not cause anything to overheat.

You really need to cook the crap out of the thing to get it into overheat mode.

My wife just reminded me that I just got this phone about 6 months ago, not a year and a half. This is my second iPhone 4, the first was replaced due to a faulty mic.
So, now I really don't get it. A dying Li-battery was at the top of my list of possibly culprits. But only after 6 months??
