How to backup photos from iPhone What should be the proper way to backup photos from iPhone. iCloud do not have much storage for it, any apps is recommended to use for backup photos? I heard a lot of users use Google Photos for backup photos, is that reliable?
Google Photos lets you store unlimited photos in high quality on their servers, just by downloading the Google Photos app. The app works great, and I've found it to be reliable. It gets 5 stars in the iOS App Store (which is really quite an achievement) and has nice extra features in the Assistant section, like auto-making videos from your photos/videos. Once your photos and videos are backed up to Google Photos, you can view them on phones, tablets, and computers, just by signing in to your account.

You can also spend $1 a month to purchase 50 gigabytes of iCloud storage, and turning on iCloud Photo Library lets you back up all of your photos similarly (though I've found this to be slightly less reliable than Google's solution).
