Performance That Matters
When it comes to performance, the processor is noticed first. Realme 15 Pro comes with Snapdragon 7 Gen 4, which is a powerful 4nm chipset. It delivers tremendous output in gaming and multitasking, especially when it is helped by its built-in active cooling fan.
Nothing Phone 3a Pro is also not behind. It comes with Snapdragon 7s Gen 3 chip, which is quite smooth for regular usage. But in extreme gaming or heavy multitasking, Realme takes a slight lead.
Battery & Charging: Beast vs Balanced
If you are a heavy user who uses the phone throughout the day, then Realme 15 Pro is the jackpot for you. It gets a big 7000mAh battery and 80W ultra fast charging. Meaning your phone will last for a long time and charging will also not take much time.
Nothing Phone 3a Pro has a decent battery of 5000mAh and 50W wired charging. It also has 7.5W reverse charging, but Realme is clearly ahead in terms of battery and speed.
Display Brilliance
For display lovers, Realme 15 Pro is a visual treat. Its 6.8-inch curved AMOLED panel comes with 1.5K resolution and 144Hz refresh rate. The most special thing is its 6500 nits peak brightness, which gives top class visibility even in outdoor usage.
The display of Nothing Phone 3a Pro is also AMOLED and comes with 120Hz refresh rate. But 3000 nits brightness and slightly small size cannot be taken to the level of Realme.
Camera Game: Zoom vs Wide
Realme 15 Pro has dual 50MP rear cameras — one Sony IMX896 sensor with OIS and the other ultrawide sensor. The front camera is also 50MP, which gives a very crisp output in selfies and video calling.
Nothing Phone 3a Pro is a surprise for zoom lovers. It has a 50MP main sensor, 8MP ultrawide and most importantly a 50MP periscope telephoto lens which gives 3x optical zoom. For those who like zoom detailing in photography, Nothing is a strong choice.
Software Experience: Bloat-Free vs Feature-Packed
The biggest highlight of Nothing OS 3.1 is its clean and minimal user interface. You get a smooth and modern experience without any bloatware. Along with this, you also get the promise of 3 years of Android updates and 6 years of security patches.
Realme UI 6 is also based on Android 15 and comes loaded with many new AI features like AI Edit Genie and AI Party Mode. But some people may find its UI a bit heavy if they are looking for a minimalistic feel.
Design & Durability
In the design department, the transparent back and Glyph Interface of Nothing Phone 3a Pro make it stand out. This phone stands out with a futuristic feel.
Realme 15 Pro mixes traditional design with durability. The IP68 and IP69 rating makes it waterproof and dustproof. If you need a robust phone, this phone is definitely impressive.
Final Verdict: What Should You Pick?
If your focus is performance, battery life, fast charging, blazing bright display and staying cool for gaming, the Realme 15 Pro should be your go-to phone. It is a complete powerhouse that handles extreme usage with ease.
But if you want a stylish, clean and intuitive experience with a unique design, strong zoom camera and long-term software updates, then Nothing Phone 3a Pro is the better pick.
Don’t just choose based on brand, choose what fits your lifestyle better. Whether you are a gamer or a photography enthusiast, a minimalist or a multitasker – your phone should also be like that!
