I have had two iPhone 5's now (swapped out the first w Apple Care for the same reason) and BOTH run very hot and have horrible battery life.

I typically let it charge overnight and at 7am when I leave for work it is 100%. Then by noon on most days it has run out.

It gets very hot and the battery rapidly drains (losing roughly a percent of power every three minutes).

When I attempt to re-charge it in the car or on the adapter it is slow to re-charge (or cant make ground against whatever is draining the battery so fast).

On the first phone, for the first three weeks I had it, it ran great. A full charge would last two days. Then it started this behaviour right after the upgrade to 6.0.1

I tried a restore. Apple Care said there was a runaway process related to getting my mail using ActiveSync with my company's Exchange server.

I disabled PUSH mail for that account to FETCH every 15 minutes and still the problem persists.

On the replacement iPhone I left it at 6.0 in case 6.0.1 was the culprit.

No dice - from the moment I got it, it started to exhibit the same behaviour. Once that was the case I upgraded to 6.0.1 and it still acts the same way.

So the odds of two phones with two bad batteries seems low.

However, there is obviously something in the iOS or software stack that is causing this issue. However, I cannot narrow it down.

I leave BT and Wi-Fi always on, but I always did before this started happening.

iPhone 5, iOS 6.0.1

    Fetch uses more battey than PUSH mail,better enable that.

    Also check Settings-> Notification Center and disable "Banner/Badge/Alerts" for all unused apps
