Why battery saver mode close my wifi?

[Onursari]

When it drops to % 20 it automatically opens and my wifi closes. when i try to open wifi, it cant open again. It opens and closes again. I open and it closes itself.. do you have this problem?

Yes, this is one of the ways WP8 saves power in that mode.

The energy saver mode should disconnect from wifi when you lock the phone. It should than enable the wifi bit it self(takes some time). Thats what battery saver options are made for, if you don't like it, disable it.

EDIT: I guess you installed the updates from this morning. It's seems like there is a bug. It disables the Wifi always under 20% now even when plugged to a charger.

I can confirm this as of today. When the phone dropped to battery saver the wifi was shut off.
