Re: how to log in with battlog?
Did you play BF4 on 360 before Xbox one or is this your first time playing BF4?
If you played on Xbox 360 and imported your soldier your Origin account on the One should have been automatically imported to your One. If you didn't play on 360 and it created and Origin account I'm afraid that you must speak to a Game Advisor at EA support in order to correct the situation.
You can reach a game advisor here: https://help.ea.com/contact-us click on the orange button on the right to start a new case, follow the instructions and when you are presented with a contact method I recommend that you use the telephone option and the “call me” option so you don't have to stay on hold for a long time. The call back feature available to North America, Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Hungary, Ireland, Italy, Netherlands, Norway, Poland, Portugal, Russia, Spain, Sweden, Slovakia, Switzerland, and the UK.
