Apple hasn’t ever been great at this whole “heat dissipation” thing, but some new developments in the supposed overheating iPhone scandal of 2009 have us wondering how widespread or reproducible these problems might be. Here are a few semi-facts we’ve managed to amass:
Somebody’s white iPhone 3GS grew some ugly brown markings during heavy use.
A new development is saying that the discoloration came from a case (pictured), not from cooking the plastic.
More users than usual have been reporting an overheated iPhone error after the 3.0 update, but as Apple’s support documentation points out, this could just be from the time of year (summer, in case you haven’t been outside lately).
There isn’t a large mass of evidence denoting a major fault to the 3GS, 3.0 or chintzy white leather cases.
So, all that said, what’s been your experience?

Back when Apple re-introduced Push Notification at the iPhone 3.0 Sneak Preview Event, Scott Forstall claimed that, unlike background multitasking that could cause an 80% drop in battery life, Push Notification would only cause a 20% drop. While some debated the truth (or truthiness) of his claims, it did set the expectation that users running Push Notification-enabled apps would see lower battery life, and gave an indicator of just how much less.

So, while it too a while, now that we finally have Push Notification, and some of the more popular messengers and games are implemented it, how’s your battery life doing?
Are you seeing a hit compared to your pre-Push Notification days, and if so, is it in the 20% range? Let us know which iPhone you have, how often you’re getting Push Notifications, and how your battery is holding up!
