    I recently tried the function to double tap the screen to enable it. After that I wondered why my 820 had such bad battery life. Then I disabled this feature again and the battery life went up dramatically.

    Tips for optimal battery usage:
    - Disable Blick
    - Disable wake up by double tap

    Update 1 requires the Developer Preview. Windows Phone 8.1 Developer Preview, all you need to know!

    If I had to guess, Blick is a localized name of Glance to him.

    I started using double tap to wake when it first came and noticed no signifigant hit in battery life, will keep using it :P

    I tried with double tap on and off and in my case I noted a little difference. In the other hand, I noted that apps that use internet (via WiFi or phone network) are the main battery consumers, even when they are not open. Facebook for example uses a lot of energy as it is working in background also... Other battery hungry apps are whatssap, mail, etc...

    << disable double tap to turn on screen >>
    This is one of the coolest feature of WP8. You've got to be kidding.

    No observable change when I did this. OTOH, disabling high sensitivity of touch - I'm seeing quite a change.

    I didn't notice any difference here. Lumia 925. I'm turning on this feature, it's awful need to click on "block button".

    ​I use Double Tap to Wake maybe 3 times a day at most... Turning off DTtW and High Sensitivity for awhile just to see...

    In 8.0 it warned you that double tap to wake would take more battery when you turned it on. In 8.1 it no longer mentions that. So I wonder if it was improved?

    LOL I forgot about this thread...

    I think a bigger drain on my 925 was the lack of Firmware optimization under the Preview for Developers.

    Now I'm using a 1520.3 with a whopping 3400 mAH battery, no Battery Saver engaged at all, Brightness and Brightness Profile maxed out with auto engaged, Glance always on, Double Tap to Wake, High Touch Sensitivity engaged and I simply don't worry about battery one bit.

    I was wondering about this too. Let's see the outcome of changing these two things (double tap, and high sensitivity).

    While I don't deny your experience, there is neither logical reason for it, nor my own experience.

    I run Glance always one, wifi always on, Bluetooth sometimes on, on both Nokia 810 and 925, no battery issues. Certainly no significant difference if I turn these features off.

    I used to have it of always before.
    But started leaving it on with my Lumia 822.
    I notice no real hit in battery consumption.
    Also, I took note that the battery drain warning is no longer there in 8.1
