    Outside of my class there is a "beehive" for all of the smartphones etc.
    I notice a battery draining while my phone is there. About 10 percent in 1.5 h'.
    What cause this?

    So you have to drop your smartphone before you go to class? If that is the case try turning it to airplane mode and see if it makes a difference.

    All the phones in proximity to each other are probably causing cellular reception issues, which would drain the battery more quickly. They could also be triggering NFC events, depending on the implementation of NFC in each phone.

    Either way, if you're not going to have the phone in your possession, you might as well turn on airplane mode to save battery. You'll get all your texts and events when you turn off airplane mode later. :)
