Hi, Apple Genius was trying to backup my iPhone last time I visited them earlier this year. They could not get it working due to some kind of secure lock that I had no idea what the password is. As I had about 6000 photos, iCloud ran out of space. If I don't do the backup and just give it to Apple to exchange the battery, will there be a danger that I will lose all the photos? Is paying a small amount to upgrade iCloud storage, upload all photos to it, get the battery exchanged, download all photos back to the phone and then terminate the increased storage contract. Is this a good approach? As I recall, I still have to pay for the whole month of increased storage service. For those who have replaced the battery, do you see increased battery life?
