    Got my replacement phone from apple last friday due to an issue with data connection (turns out it was a faulty sim card, not the phone itself, but I still got a new phone). Took it home, charged it and set it up like usual (from iCloud backup). After I had set it up, i noticed that the battery was draining REALLY fast, i`m talking about 1 - 2 % every 3 minutes. So I waited until the phone completely shut down because of no battery, and charged it back up to 100% to see if battery calibration would help. At this time, it was already midnight so I unplugged the phone from it charger, and shut down every background app and such, and put it on my nightstand (I did also disabled location services, siri, bluetooth, auto-set time because I saw it could increase battery life on a few websites). Next day, my battery was down to 41%! The first thing I did was to go into settings and look at my battery stats (where you can see how much the phone has been idle and in use). There I saw that the phone have spent 8 hours in idle, and 7 hours in use, just over the night! This is really weird, because I shut down any apps that was running in the background.
    Later that day, I did a full restore from DFU mode, set up as a new phone and re-installed a few apps, but the phone still drains a few % every 5 - 10 min on idle, and it still shows up in the battery usage meter that it`s been in use, even though it was idle all the time!

    TL;DR Noticed phone draining battery fast. Calibrated it ( to 0% and back up to 100%) over night, when I woke up, was down to 41%. Took phone in DFU mode and set up as a new device. Battery still drains relatively fast, and still battery usage meter sais it`s been in use even though it`s been in idle.

    My question is this: Do I ask for a new phone or do I wait for iOS 5.1 to see if it fixes the battery drain?

    You can ask for a new phone, doesn't mean they'll do it. But your situation sounds like it is on the extreme side.

    Well here in Norway, we have an epic guarantee policy, so getting a new phone won`t be a problem. I was just wondering if iOS 5.1 would fix these issues or is it just my phone.
