    Good morning

    Yesterday when I went to bed I disconnected my Lumia from with 100 % battery level and connected to WiFi with battery saver switched to always on

    Today I'm late to work because my Lumia is dead with 2% battery level

    I checked what is working in background but there is nothing wrong

    How you got idea what happened

    Thank you for advice & have a good day

    Hi! Are you on Lumia Denim update? If you are on Denim this is normal, because with this update the battery drains faster.

    That is not normal at all. Sheesh some people on this forum are strange. I found battery life slightly improved and drainage overnight around 0.5% per hour. There maybe some rogue programme running in the background. Try a reset, try measuring it in flight mode, then a hard reset and failing that get it looked at. No phone should drain in 6 hours on idle despite what the helpful previous poster says!

    Why would you turn on battery saver (to always on!!) when you have 100% battery? If you are doing that every night (or very often) your battery is dying now

    Good morning

    AV2RY - Would you like explain why battery will be dying if I use battery saver ? Without battery saver my phone disconnected at 6 am at 1.30 pm has 15 % battery Battery saver give me additional life time

    But ...

    Paul 1266 - I tested time life with battery saver off and its strange
    Phone use only 8% during whole night
    But before I had very high battery use by Tweetium and Flipboard

    Maybe sometime there is any conflict between battery saver and apps and in results apps use abnormal power

    I'll write if will be there any changes

    Cheers

    This is plain wrong of you to say that Denim drains the battery faster than before.

    May I ask how you came up with that? Did you perform a scientific study on large number of 930s and found this out?

    Stop making statement-like assertion based on your own personal experience as it can be misleading to other people!

    Try to remove your email accounts from your phone, restart the phone, add them back and set them to check for new mail every 30 minutes or less often.

    Maybe the email app got stuck on continuously checking for new mail.
