Start with the full product name
Xiaomi calls the 4G phone simply Redmi Note 15 Pro. It uses a Helio G200-Ultra processor. The Redmi Note 15 Pro 5G uses Dimensity 7400-Ultra. Ask for the complete name and regional specification if a shop listing leaves you guessing.
This comparison is for those two global versions. The Redmi Note 15 Pro+ 5G is another model, so don't let a missing plus sign send you towards the wrong offer.
The hardware differences worth knowing
Here are the main global specifications, with the 4G model first and the 5G model second:
- Screen: 6.77-inch AMOLED at 2392 × 1080 versus 6.83-inch AMOLED at 2772 × 1280. Both support up to 120Hz.
- Weight: 195g versus 210g. I'd try the grip if possible, especially if you prefer a lighter phone.
- Battery and wired charging: 6500mAh and 45W versus 6580mAh and 45W.
- Rear video: up to 1080p at 60fps versus 4K at 30fps. The 5G version also offers 1080p at 60fps.
Memory card or eSIM: this could decide it
The 4G phone supports microSD expansion up to 2TB. Its hybrid tray takes either two SIMs or one SIM and a memory card, so you can't fit two physical SIMs and microSD together. Check card compatibility before buying.
The 5G phone doesn't support SD cards. If you keep lots of videos or offline files, I'd budget for enough internal storage from the beginning. You can't add a memory card later just because the similarly named 4G model can.
For eSIM, the position reverses. The 4G model has no eSIM support; the global 5G specification lists two nano-SIMs or one nano-SIM plus eSIM, depending on country, region and carrier. Confirm your exact handset with the operator before buying an eSIM plan.
The 5G phone supports 4G networks too. I'd check the coverage where you spend time rather than assume the badge guarantees a faster connection everywhere.
Both say 200MP, but video is a different story
Both have a 200MP main camera with optical image stabilisation and an 8MP ultrawide. If 4K rear video is on your must-have list, though, the 5G version is the one that lists it. The global 4G model stops at 1080p.
Selfie cameras differ too: 32MP on the 4G phone and 20MP on the 5G. I wouldn't pick a winner from those numbers alone. Look at comparable photos in the lighting you use, and see my guide to Redmi video modes if the camera specifications feel confusing.
Keep the battery and water ratings in perspective
The battery-capacity difference is just 80mAh, about 1.2%. That doesn't establish which phone lasts longer. Both advertise up to 45W wired charging, but that isn't a promise of identical charging times either. Global box listings include an adapter, with contents varying by region.
The 4G specification lists IP65, while the global 5G sheet lists IP66, IP68, IP69 and IP69K under controlled tests. I'd treat these as protection ratings, not a reason to deliberately get a phone wet. Protection can deteriorate, and Xiaomi advises against testing the 5G model yourself or using it at a beach or pool.
Which one would I put on the shortlist?
I'd lean towards the 4G model if removable storage matters most and its network support meets your needs. I'd favour the 5G model if 4K rear video or supported eSIM use is essential. If gaming decides it for you, look for tests of your actual game rather than trying to rank the phones by processor names alone.
Then compare current local offers for the exact RAM, storage and sales region. Get the charger contents and warranty terms clear, and check NFC on the local variant if you need it: availability varies by market on both global specification sheets.
Finally, check the model’s update support. Buying the feature set that suits you is only part of choosing a phone you want to keep.
