My icloud refreshed the information of my new phone when I turn on my old phone
Hi! Until April I had an Iphone 6S, but I bought an Iphone Plus 8. I didn´t close my icloud account in my iphone 6s until yesterday when I turn on my iphone to erase all my information. My iphone 6s with my icloud account there was turned on all day because I left it at home charging. I didn´t erase the information inmediatly when I turned on it.
Then, at the afternoon I saw in my Iphone 8 that all the information from april till the last saturday wasn´t there.
I don´t know what happened but I would like to recover my photos of my Iphone 8, but I presume that the icloud refreshed the account considering the information that was in the iphone 6s :(.
Someone could help me please. Maybe you know how can I recover the information of my new phone.
iPhone 8 Plus, iOS 11.3.1
