    Hiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii,
    I noticed my Lumia 525 get hotter at the back and drains a lot of power whenever I play on my phone.
    I charge 3 times per day, battery drains is very serious.

    So I made a small simple test on my phone to find out which situation cost power the most.

    System:
    Email+accounts: Sync manually
    Internet sharing: Off
    Lock screen: 30 seconds
    Screen rotation: Locked, portrait
    WiFi: On, unchecked all advanced settings.
    Bluetooth: Off
    Flight mode: Off
    Mobile network: Off, don't roam, 2G, manual select.
    Location: Off
    Kids' corner: Off
    Battery saver: Off
    Date+time: Set manually
    Backup: Off
    Brightness: Auto, low
    Find my phone: Disabled
    Phone update: Disabled
    Feedback: Disabled
    Touch: Normal sensitivity, no double tap to wake.


    Applications:
    background task: All blocked EXCEPT battery app
    data sense: Reduced data
    games: Connect xbox off


    Apps installed and running:
    Battery, facebook, whatsapp, line, skype, viber.

    Condition:
    Dark room with no light.

    Testing:
    I leave my phone beside and I go to sleep.
    Battery drops 3% in 8 hours.

    Surf facebook over WiFi.
    Battery drops 10% in 30 minutes.

    Screen on, idle. (Lock screen timeout: 5min)
    Battery drops 3% in 30 minutes.

    *Screen on, finger on screen, sliding up and down non-stop. (Lock screen timeout: 5min)
    Battery drops 11% in 30 minutes.

    *Play Fruit Ninja, max volume.
    Battery drops 13% in 30 minutes.

    Play Temple Run, max volume.
    Battery drops 7% in 30 minutes.

    Youtube over WiFi, max volume.
    Battery drops 8% in 30 minutes.

    WiFi Hotspot, 3G data, screen off.
    Battery drops 20% in 1 hour.

    GPS, 3G data, screen on, Waze.
    Battery drops 50% in 1 hour.

    Conclusion:
    -

    Situation may differ from other user.
    Just for your references.

    Sounds like your battery could be bad, because that sounds really bad... How old is your phone?

    My non-scientific opinion is having the screen on is what uses the most battery, not your finger. The less the screen is on, finger or not, the lower the battery use.

    Hehe, because I was testing in a condition of dark environment, screen brightness was low. (Not lowest because battery saver is off)

    Ok, then I think you should send it back, because that doesn't sound normal

    I was facing the same problem too in the beginning with my 12 day old 525, but now the battery backup has increased and lasts a day easily, with 2g net turned on all the time. The guy at the shop told me that when we use 3G on the device, the battery gets drained quickly, so switch to 2g for basic net usage and 3g for surfing.
