RAM Versus ROM

Before we go any further, we need to take a moment to explain the difference between RAM and ROM. Let’s start with ROM. The name stands for Read Only Memory, and it refers to a type of memory that doesn’t allow modification of stored data. This type of memory usually contains programs and routines that stay as they are during the entire lifespan of the memory.

A good example are the chips that were used in old gaming systems like Nintendo or Sega Genesis. There’s also a ROM chip in your personal computer, which takes care of the initial startup process. Other examples include chips in calculators, digital clocks, home thermostats, electrical garage doors, etc.

ROM chips are typically just a few MB in size, whereas a single RAM (Random-Access Memory) chip can store multiple GB of data. These days, your typical PC or laptop would have between 4 GB and 8 GB of RAM, and the typical high-end smartphone has 4 GB.

Data can’t be stored in RAM without a constant source of power. Without it, the chip would lose all the information that was stored on it in a matter of minutes. The main advantage of RAM is that it allows data to be accessed in almost the same amount of time no matter where they are physically located inside the memory chip. This results in very fast read and write speeds, which are so crucial for demanding applications and work scenarios.

Why You Need More RAM

RAM allows your smartphone to almost instantaneously store and access information that it needs to perform various computing tasks. A game might store its assets into RAM to allow you to seamlessly transition from one area into another, and, for example, your web browser uses RAM to store web pages, so that you don’t have to reload the page every time you switch to a different tab.

If you don’t have enough RAM, your experience will suffer, and you might not even be able to run some of the most demanding applications and games. The good news is that smartphones with 4 GB of RAM and more are becoming increasingly more common with each passing month.

Best Smartphones with the Most RAM


1. Asus Zenfone 3 Deluxe

The latest member of the Zenfone family of high-end devices has a lot in store for potential customers. Asus has taken the best components currently available and somehow managed to cram them into a gorgeous metal body with 4.2mm thin edge. Doing this requires 240 precision steps, including hyperfine sanding process, which polishes the surface and gives it a smooth anodized finish.

So, what exactly are the specifications of the Zenfone 3 Deluxe? Nothing less than the new Snapdragon 821 chipset with 6 GB of RAM and Adreno 530 GPU. The 821 is engineered to deliver faster speed, improved power savings, and greater application performance. In other words, you won’t encounter any game too demanding nor any application too power-hungry.

At 5.7”, the Zenfone 3 is one of the largest smartphones currently available, so it may come as a surprise that the screen doesn’t have 2k resolution. But when you consider that it still has 386 ppi pixel density, it becomes obvious that there’s nothing to worry about. Indeed, the AMOLED capacitive touchscreen looks great even under direct sunlight, allowing you to shoot stunning pictures using the impressive 23 MP camera with 4-axis optical image stabilization. The camera takes just 0.03 seconds to come into focus, ensuring that you won’t miss any special moments.

Unsurprisingly given how thin the smartphone is, the 3000 mAh battery is non-removable. Luckily, Asus did a really good job when it comes to software optimization, resulting in a whole day of usage on a single battery charge. And like with all Snapdragon chipsets, the new 821 also comes with Quick Charge 3.0 fast charging technology.


  • 6 GB of RAM
  • 23 MP camera
  • Stunning metal design
  • Performance


  • “Only” full HD display

2. Samsung Galaxy S7 Edge

Many consider the Samsung Galaxy S7 Edge to be the best-looking smartphone currently available. Why wouldn’t they? Samsung, a company that is constantly battling with their biggest rival, Apple, for the position of the most popular manufacturer of premium smartphones and tablets, has finally demonstrated their ability to come up with an original design that stands out and screams luxury.

Sandwiched between a metal rim is a Gorilla Glass 4, which protects the remarkable 5.5” Super AMOLED capacitive touchscreen with 1440 x 2560-pixel resolution and 534 ppi. The display uses Samsung’s always-on display technology to keep users constantly up-to-date on the latest notifications and messages.

When you unlock the smartphone, you will be greeted with the TouchWiz user interface. TouchWiz plays an essential role in exposing all the complex functionality that all smartphones from Samsung are known for in such a way that it won’t overwhelm users. It actually does a pretty good job, but don’t expect that it won’t take you some time before you get used to it, especially if you are coming from a stock Android and not some other alternative UI, such as MIUI from Xiaomi.

Unlike with the OnePlus 3, the Galaxy S7 comes with “only” 4 GB of RAM. You can take our word that you won’t ever find yourself longing to have those extra 2 GB. The Snapdragon 820 chipset with Adreno 530 GPU ensure state-of-the-art performance, and the microSD card slot allows you to use cards up to 256 GB in size.

That’s a lot of room for all your pictures and videos taken using the 12 MP, f/1.7 camera with phase detection autofocus and powerful LED flash. You might have heard a thing or two about the quality of Samsung’s cameras. Well, the camera in S7 is probably the best camera that you can currently get. Period. It beats even the latest iPhone, and that says a lot. If you want a great camera phone with more RAM than you will ever need, the Galaxy S7 Edge should be on top of your list.


  • The best camera you can currently get
  • Flawless design
  • Performance
  • Battery life
  • Display


  • TouchWiz takes some time getting used to

3. OnePlus 3T

The OnePlus 3T is a truly impressive smartphone from a company that knows how to make the world pay attention. This 5.5” beauty with full HD resolution is made out of aluminum, which offers excellent durability and makes the smartphone feel like the premium device it is.

Inside is the Snapdragon 821 chipset, which represents the cutting-edge technology available in smartphones and tablets. Qualcomm, the manufacturer of the chipset, have managed to combine ultra-fast performance with long battery life and excellent connectivity into a single package. The presence of 6 GB of RAM means that you will be able to squeeze every ounce of processing power out of the chipset and enjoy lag-free gaming and multitasking experience.

Speaking of multitasking, one application that you will definitely find yourself opening on a regular basis is the camera app. The 16 MP rear sensor with phase detection autofocus and optical image stabilization is just such a pleasure to use. Not only does it take clear pictures in all conditions, but it also shoots 1080p at 30 frames per second. Of course, the front-facing camera has nothing to be ashamed about. At 16 MP, its image quality is above most rear-facing cameras found on mid-range devices.

The one thing missing is a slot for a microSD card. OnePlus felt that – especially with the prevalence of cloud storage – most people would be satisfied with 64 GB and 128GB of internal storage space. Truth be told, the option to use a microSD card would be useful from time to time, given how large 1080p videos can be. At least, you still get two SIM card slots.

The OnePlus 3T is powered by a 3400mAh battery, which can last you an entire day, depending on your usage. But even if you run out of juice, charging it to 60% takes only 30 minutes.


  • Excellent performance
  • 6 GB of RAM
  • Camera
  • Build quality


  • No microSD card slot

4. ZTE Nubia Z11

Released in July of this year, the ZTE Nubia Z11 is the newest device from a Chinese manufacturer that deserves a lot more attention in the west. ZTE Corporation was founded in 1985, and their core products are wireless, exchange, access, optical transmission, and data telecommunications gear; mobile phones; and telecommunications software. They are currently among the top 10 largest smartphone manufacturers across the world, and we predict that their position could be even higher next year.

That’s because the Nubia Z11 has what it takes to compete with the big guys. For starters, the elegant aluminum smartphone comes with 6 GB of RAM and the Snapdragon 820 chipset, making it perfect for powerusers who are looking for the maximum performance money can buy.

The full HD, 5.5” capacitive touchscreen has 403 ppi pixel density and is covered with Corning Gorilla Glass 3 for maximum protection. Nubia uses their own UI, nubia UI 4.0. The user interface is designed to make the mobile experience come alive with apps that respond to real-life conditions, often removing the need for distracting push notifications.

Well-integrated into the UI is also the access to the 16 MP rear-facing camera and the 8 MP front-facing camera. The main camera has a dual-LED flash, phase detection autofocus, support for geo-tagging, and lot of other useful features that are there to make your life easier and your pictures better.

Other things that are worth mentioning are the presence of a USB Type-C 1.0 reversible connector and a fingerprint scanner. The Z11 lives on the power supplied by the 3000 mAh non-removable Li-Ion battery. It seems that the new UI could use a bit of tweaking, as the smartphone doesn’t last as long as other devices with the same battery, but we are sure that it’s only a matter of time before Nubia squishes even the tiniest bugs.


  • 6 GB of RAM
  • Plenty of built-in storage space
  • Relatively affordable
  • Great camera
  • Stylish design


  • Availability


5. LG G5

With the LG G5, they decided to show the whole world that they are not afraid of making bold moves and doing something different, which is something we don’t see as much as we would like to. What makes the LG G5 so unique is its modular design, which lets you swap the battery cover and replace it with either a camera grip with dedicated shutter buttons or for an audiophile-grade DAC. At this stage, the line-up of accessories is still too small to tell whether it will take off as something that other manufacturers will copy, or if it just going to be a gimmick that only a very few people use.

Whatever the case is, the pleasantly compact 5.3” smartphone has plenty of other things going for it. It comes with the powerful Snapdragon 820 chipset that we see in so many flagship devices. The chipset is accompanied by 4 GB of RAM and 32 GB of internal storage space, which is extendable with microSD cards.

Avid mobile photographers will surely appreciate the 16 MP rear-facing camera with LED flash. It takes great pictures and records even better video in 2160p at 30 frames per second. If you get the LG CAM Plus module, you will be able to also enjoy enhanced camera capabilities and manual camera features, including a dedicated zoom wheel and shutter button.


  • Weide angle camera
  • Performance
  • Removable battery
  • Compact form-factor
  • Modular accessories


  • Subpar design
