If I factory reset my iPhone will my iCloud be deleted?

My iPhone 6 has been having some battery troubles where it drains extremely fast and the phone is visually being more slow, I read that factory resetting your iPhone can help with the battery life and cause your iPhone to speed up. In doing so I have a lot of photos on this phone that are all on my iCloud account, I was just wondering if in doing such an act as resetting my iPhone will my iCloud photos, contacts, notes, etc. be deleted? Thank you! 🙂
