If you look up the product specifications of any iPhone model at Apple’s website, you won’t find one important information — how much RAM the iPhone has.
Although the company doesn’t reveal it to the public, the amount of RAM in iPhones eventually becomes known because of device teardowns and sleuthing by hobbyists and the technical community.
Here’s the list of all iPhones and how much RAM they have.
If you saw your phone on the list and were surprised to see that its RAM is lower than you expected, don’t be disappointed. With all of Apple’s optimizations and the seamless hardware-software integration, the iPhone can still do its job just fine despite typically having lower RAM than similarly priced Android smartphones. In fact, it may even perform better than the competition.
Here’s an example: a speed test by PhoneBuff between the iPhone XS Max and Samsung Galaxy Note 9. The result showed the iPhone XS Max beating the Note 9, even though the former has less the amount of RAM than the latter at 4GB versus 8GB. PhoneBuff’s speed test between the latest flagship smartphones—the iPhone 13 Pro Max (6GB of RAM) and Galaxy S21 Ultra (12GB of RAM)—also had a similar result.

Still, the RAM is a main factor to consider when you’re buying a new smartphone. Knowing how much there is in a phone should help you decide if it’s worth buying or not. Basically, a smartphone can handle and access more data quickly when it has more RAM.
If you’ve had a budget-friendly smartphone that skimps on RAM, you may have noticed that it would need to relaunch apps often as you switch apps. This happens less frequently on a high-end smartphone with more RAM as it can keep more apps open.
