Some want the best screen, while others want the best camera system. Many will value battery life or something like performance. But those who want the best multitasking performance will want to get a phone with as much RAM as possible. Phones with 16GB of RAM are leading the race right now, and we’ve compiled a list of the best available. Let’s learn more about RAM and explore the options to find your next multitasking beast.
How much RAM do you really need?
First things first, you have to wonder if you even need a phone with 16GB of RAM. To be honest, we feel like it would be a little overkill to have that much RAM on a smartphone. In 2019, we delved into this topic and came to the conclusion that from 6 GB to 8 GB is the most suitable amount. Anything above that didn’t matter then. Has anything changed in a few years?
In August 2021, we conducted a survey asking people how much RAM they think is appropriate for use in a smartphone. Answer #1 – 8 GB with 31.7% of the votes. 6 GB was the second most popular option, with 25.97% of the votes. Does this mean phones with 16GB of RAM have too much RAM? Chances are you won’t notice a difference in performance once you go beyond 10GB or 12GB of RAM.
This does not mean that you should not choose one of the best phones with 16GB of RAM. It’s always good to be prepared for the future, especially if you plan to keep your phone for years. Standards and resource needs change, so perhaps 16GB of RAM won’t be considered as such when applications start requesting more memory resources.
We also have to consider that if a phone has 16 GB of RAM, then most likely it is also a great high-end smartphone with great specs and features. We assume that this may be the best way to make a decision. While having 16GB of RAM is fantastic, you probably shouldn’t buy a phone for that reason alone. Make sure the rest of the phone is also excellent. That’s why we’re here to help you find the best ones.
Editor’s note : We’ll be updating this list of the best phones with 16GB of RAM regularly as new devices are released and old ones are phased out.
Samsung Galaxy S21 Ultra 5G

If you’re looking for one of the best phones with 16GB of RAM, the Samsung Galaxy S21 Ultra 5G is likely to be the safest choice. It not only has all the necessary RAM, but it is one of the most popular smartphones in the industry. Its specs, design, and features are amazing, and since it’s a Samsung smartphone, it’s likely to hold its value better than the rest of this list if you ever want to sell it.
You will have to purchase the most expensive version of the smartphone to take advantage of the 16GB of RAM. This means that you will also get 512 GB of internal storage. Other specs include a large 6.8-inch dynamic AMOLED display with a 120Hz refresh rate, a powerful processor, a quad-camera that is known to take amazing photos, and a large 5000mAh battery.
Not only that, but also that the phone is part of Samsung’s premium lineup. It is very well made and looks great. We should mention that Samsung has released the Galaxy S22 Ultra, but this device has 12GB of RAM. That’s why we didn’t remove the previous iteration.

Owner confusion aside, these are some of the best phones with 16GB of RAM, especially if you want a high-end phone that doesn’t even come close to the $100,000 mark. Alternatively, you can purchase the standard Red Magic 7 versions with either 12GB or 18GB of RAM.
Even though they cost less than their competitors, the phones are still impressive. Both have Snapdragon 8 Gen 1 chipsets. There is a 6.8-inch 165Hz display, triple cameras, big battery and fast charging.

Inside, you’ll find a Snapdragon 8 Gen 1 chipset, a powerful triple-camera system, and a great 5,000mAh battery. The 6.8-inch display features AMOLED technology and an excellent 120Hz refresh rate. More importantly, it’s a phone you won’t be ashamed to pull out during an important work meeting.
Again, the only bad news is that you will have to purchase the most expensive version to enjoy 16GB of RAM. But you also get 1TB of internal storage. This should be enough for all the apps you will be using at the same time.
