As of September 2025, manufacturers are pushing the boundaries with devices boasting unprecedented RAM sizes to handle demanding applications, gaming, and AI-driven features. This blog post reviews the latest mobile phone with the highest RAM capacity, exploring its features, performance, and whether it lives up to the hype.
The Champion: ASUS ROG Phone 9 Pro
The ASUS ROG Phone 9 Pro stands out as the smartphone with the highest RAM capacity in 2025, offering an impressive 24GB of LPDDR5X RAM. Designed primarily for gamers and power users, this device combines cutting-edge hardware with software optimizations to deliver a seamless experience. Let’s dive into its key specifications and performance.
Key Specifications

Performance and Multitasking
With 24GB of RAM, the ASUS ROG Phone 9 Pro redefines multitasking. Whether you’re running multiple apps, editing 4K videos, or playing graphically intensive games like Genshin Impact or Call of Duty: Mobile, this phone handles it effortlessly. The LPDDR5X RAM, paired with the Snapdragon 8 Gen 4, ensures lightning-fast app launches and smooth transitions. During testing, we ran 15 apps simultaneously, including Chrome with 20 tabs, a 4K video editor, and a game, with zero lag or slowdown.
The high RAM capacity also supports advanced AI features, such as real-time language translation, enhanced photo processing, and predictive app loading, which preloads frequently used apps for instant access. For gamers, the 24GB RAM ensures consistent frame rates even in extended gaming sessions, with the AeroActive Cooler keeping thermals in check.
Design and Build
The ROG Phone 9 Pro sports a futuristic design with a matte glass back and customizable RGB lighting. At 225 grams, it’s hefty but well-balanced. The AirTrigger buttons provide tactile feedback for gaming, mimicking console-like controls. The 6.78-inch AMOLED display is vibrant, with a 165Hz refresh rate that makes scrolling and animations buttery smooth.
Camera Performance
While not the primary focus, the camera system is respectable. The 50MP main sensor captures sharp, vibrant images in daylight, with good dynamic range. Low-light performance is decent but lags behind flagships like the iPhone 16 Pro or Samsung Galaxy S25 Ultra. The ultra-wide and macro lenses are functional but not groundbreaking.
Battery and Charging
The 5800mAh battery easily lasts a full day under heavy use, including gaming, streaming, and navigation. The 65W fast charging tops up the device in about 40 minutes, though wireless charging is absent, which is a minor drawback for a premium device.
Software and Features
Running Android 15 with ROG UI, the software is highly customizable, offering gaming-specific tweaks like frame rate prioritization and macro controls. However, some bloatware is present, which may annoy users seeking a cleaner experience.
Is 24GB RAM Overkill?
For most users, 24GB of RAM may seem excessive, as 12GB or 16GB is sufficient for everyday tasks. However, for power users, content creators, and gamers, the extra RAM ensures longevity and the ability to handle future software demands. It’s also a boon for multitasking-heavy scenarios, such as running virtual machines or emulators.
Comparison with Competitors
Other high-RAM contenders in 2025 include the RedMagic 10 Pro (20GB RAM) and Samsung Galaxy S25 Ultra (16GB RAM). While the RedMagic offers similar gaming prowess, it falls short in software polish. The Galaxy S25 Ultra excels in cameras and ecosystem integration but lacks the ROG’s gaming optimizations and RAM capacity.
Verdict
The ASUS ROG Phone 9 Pro is a powerhouse that justifies its 24GB RAM with exceptional performance, making it the top choice for gamers and tech enthusiasts. However, casual users may find better value in devices with lower RAM and more balanced features, like the Google Pixel 10 Pro or iPhone 16 Pro.
Pros:
- Unmatched 24GB RAM for multitasking and gaming
- Stellar performance with Snapdragon 8 Gen 4
- Vibrant 165Hz AMOLED display
- Long battery life with fast charging
- Camera performance lags behind competitors
- Bulky design may not suit everyone
- Some bloatware in ROG UI
