How do I stop iPhone from asking for log-in info?
My iPhone 5 keeps asking me for a Yahoo log-in. I have never set up anything for Yahoo on my phone. I get prompts hourly, sometimes more often, and it's annoying as heck.
I think my phone blows through the battery overnight because of this. I can go to bed with 90% battery life and wake with 15%.
iPhone 5, iOS 9.2.1
