What is wrong with my device after the update?

I have a LG g2 and recently the lollipop update was installed on my phone, every since the update has been installed my phone has went to hell I used to love my g2 but now it's slow the battery life is horrible it won't stay connected to my wifi and unfortunately in my car the music won't sync up anymore to my cars Bluetooth. Is there any kind of way I can remove the update from the phone I really don't want it no matter how cool it looks it sucks.

The only 2 options you have are:

1: Factory rest WITHOUT backing up apps and app data, do not auto restore.

2: Ask for a warranty exchange from Verizon, then update the replacement phone immediately BEFORE setting it up.

3: (wait for 5.1 update)
