So I ran into kind of an interesting problem today.Keeping in mind that the only thing on is 3G, before going to bed, I picked up my phone to run a quick check of my email. I also checked the usage as over the past few days, I have been trying to get a good idea as to whether or not I have a defective battery. It read, "1 hr 47 min". When I woke up this morning to check my mail again at around 9, it read " 3hr and 28" min. Unless I was sleepwalking, which I doubt, there is no way I could have been using the phone. So I wiped my phone(in case I could get an exchange), and I took it over to the genius bar this morning, and he told me that Yahoo(which I have set up on the phone cause I have an account) supposedly has a special setting under "Mails,Contacts,Calender" that still forces the Yahoo account to check for new messages, even when the main push settings are turned off. This sounded like a plausible explanation, so I decided to let it go and come home. However, once I returned home, and restored the phone, I could not find such a setting! Am I missing something here? or do I have a defective battery? If it helps at all, my Yahoo account is just the standard free account. Also, the glass on mine is not even...and possibly bowed downwards in the middle. The reason I say this is cause, (looking directly at the face of the phone, home button on the bottom) the upper left is pretty much flush with the bezel, the lower right and left corners are about the same height, but not flush with the bezel and raised just slightly above it, and the upper right corner is noticeably raised up more then everywhere else. At first I thought I was just seeing things, but after placing a sturdy plastic ruler on the face there's a definite opening in the middle between the ruler and the glass. I did bring this up with the genius I went to go see this morning and he told me he checked 4 other phones and that they all had similar defects. Im not sure if I should try for an exchange or not given that I have no other issues with the phone besides those two. This is already my 4th phone(had light leaking out the first 3)...opinions please? Has anyone received or exchanged for perfect phones in the past few days? Thanks!
