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?
