iTunes lets you store as much data as you want for free, and it's only for iPhones. The biggest downside, you have to do it all manually:

Open iTunes and connect your iPhone to your computer.
A message will pop up, asking if you want to Trust This Computer, tap "trust" or "allow."
Select your iPhone when it appears in the sidebar of iTunes. If your device doesn't appear in iTunes, here's what to do.
Click Back Up Now.

After connecting your iPhone to your Mac, click on your phone's icon on the left sidebar and then click "Back Up Now" (highlighted in red).

The great part about Android phones is that they do most of the backing up for you. But, this completely relies on you signing into your Google account on your Android phone.

You probably already did this when you first turned on your phone. If you didn't, or don't want to sign into your account, refer to option 2 below this section.

Through this account, Google automatically backs up most of your data -- including the details of your Android settings, display preferences, wifi networks, passwords, etc. Your account also uses Google Photos to back up photos and videos.

If you ever want to confirm that Google is backing up your phone, double-check all these things:

Go to Settings.
Tap the search engine bar at the top and search for "Back up" (two words).
Choose the first option that shows up -- it varies depending on what type of Android phone you have.
If your phone shows "Back up to Google Drive" at the top of the screen, make sure it's toggled on, OR
If your phone shows "Back up my data" and "Automatic restore," make sure both are toggled on.
And in case you forgot which email you used, below that toggle is the Google account associated with your system backups. To change this account, press on the line showing your current Google account, and choose from a list of accounts connected to your phone.

If you really don't trust what you can't see, you can transfer all your Android phone data to your computer instead using the guide in the next section.
