A 108MP f/1.7 main sensor, 1/1.67 inch, on a phone that weighs 174.5 grams and runs a Dimensity 6080.
In daylight it takes genuinely good photos. The megapixels are mostly used for binning, so you get a cleaner 12MP image rather than a 108MP one.
The same headline number, but paired with a Snapdragon 8+ Gen 1. Camera processing is compute work, and a faster chip shows up in how quickly the phone handles HDR and night shots.
Same sensor size class as the Redmi, better silicon doing the maths.
The 180MP sensor here is the periscope telephoto, not the main camera. The main is a 50MP with a variable aperture.
That is the more useful arrangement. Zoom is where extra resolution genuinely helps, because you are cropping into the frame anyway.
Sensor size beats megapixel count. The Find X7 Ultra has a 1 inch type main sensor at 50MP and will out-shoot a 108MP phone in poor light almost every time.
When you compare cameras, look for the fraction after the megapixels. 1/1.3 is bigger than 1/1.67.
