    i have read conflicting reports about leaving the wifi on all the time or off to save battery life.

    anyone with direct experience to know if it even makes a difference?

    A lot of people say if you leave wifi on but are not connected to wifi, it will not hurt battery life. I'm not sure I believe that anymore as I have seen a fair amount of battery usage from wifi when not connected over the last couple of months. I, now, try to remember to turn wifi off if I won't be connecting to wifi for a longer period of time.

    I have the Wifi ON all the time and I get around 18-20 hrs of battery life, with around 40-30% battery charge

    Leaving wifi on will drain battery a little because it is constantly searching for a signal.

    Turn off the option to notify for open networks under the advanced options. I leave mine on constantly and dont have an issue with massive battery drain.

    Have the best of both worlds. Use Y5 battery saver and it will take care of turning WiFi on and off when you get near one of your ap . It uses tower data.

    how about if you leave wifi on but it is connected?

    does that drain the battery a little?

    The new KitKat "upgrade" is now eating my battery. Not lasting more that 6 hours, and the phone is hot.
    What's the problem here?
  9. Did you do a Factory Data Reset after the upgrade to Kit Kat? It is always recommended when upgrading to a new major version.

    Mine is not that bad but it is worse than before. I used to go literally 9 or more days without charging but now I'll eat up 10% in a short time. Then again I am playing with it quite a bit setting it up.

    Another option is in the advanced section of the WiFi settings where you can tell it to ignore weak wifi signals. This way, it won't keep trying to connect to a weak signal.

    I myself have it set up so that Smartactions turns my wifi on when I'm at home and at work (wifi access at work). Otherwise, wifi is turned off (default) outside of those areas. Otherwise, if you are in an area that does not have wifi, it will keep searching for wifi which can drain your battery.

    For me, I can go an entire day and a half without charging which is the same as it was under JB.
