So I left my new iPhone 5 off the charger last night to test idle battery drain. My 4s would drain about 5-10% overnight, depending on notifications that came in, etc. My Samsung Galaxy S III would drain around 10-15%. Woke up this morning and after 6 and a half hours of being idle, my iPhone 5 was still at 100%. Really? Is this real? Anyone else experiencing the same results? I have 4 e-mail accounts, including two exchange accounts and several other services connected, such as IM. Please tell me this isn't a battery gauge glitch, because if not, it's epic.
