You should be there (where the pics were taken) to appreciate which picture is more accurate. On the other hand, you can adjust the saturation from app. And more, not the saturation is the indicator for a good picture, but the dynamic range, the level of details etc.

iPhones can capture P3 colour gamut and hence the pictures have the potential to look more vibrant. But thing is, Pixel's processing has set a much higher benchmark in terms of photography that iPhones just cannot match it yet. But the sensor's colour capture advantage shows in video capture, iPhone's fottage are naturally more vibrant.


As for why the Vivo device image looked as vibrant like iPhone, maybe they have more saturated images than natural, like Realme phones (Vivo is the parent company afterall). Capturing a wider colour space and capturing a more saturated image are totally different matter. Its just preferences , who likes what. Natural doesn't mean unsaturated, and wider colour don't necessarily mean more saturated.

Thank you. I am not into this line so couldn't understand most of the part. It would be great if you could answer this:
Can i click pics like iPhone or vivo? If so then how?

Thanks

My first attempt at astrophotography with my Poco. Only the phone was used, both for taking and processing the photo. Conditions were not ideal as it was slightly overcast and high humidity. This is a composite of 20 separate RAW 15s exposures at iso800 processed using the Siril run in the Ubuntu environment on the phone (UserLAnd). It could have been even better if I didn't forget to take multiple dark frames in the same conditions.

Can you send me full picture? Did you use SuperRes? No astronomical instrument?
This is the cleanest and best astro capture taken with Poco. Nice!

PS: tried to enhance it, if you don't mind. :)
Thanks, but even though the result is encouraging, it's actually much-much worse than it could have been. I've actually taken about 60 photos (just a phone on a small camera tripod) and only later discovered that only the first ~20 are usable due to clouds so the total exposure is quite short. I also should have taken dark frames (same exposures but with the lens covered) parallel with the light frames (maybe switch every 10 exposures - it is important that the CCD is at the same temperature for both). That way I could have eliminated the thermal noise much better. On this photo the thermal noise was not removed completely so you get those ugly dark lines in the background (that was the reason I didn't boost the final brightness so much).
For taking the photos I have used DeepSkyCamera that conveniently has all the features (intervalometer + RAW + full manual controls).

Here is the link to the full-res photo:

The result is beautiful, having in mind that it was made using a... phone camera. I'm (better, I was) also an astrophotographer, a planetary one, but I know how difficult it is to capture deep space objects. :)
Very nice photos!
If the camera has RAW and manual controls then the sensor quality becomes irrelevant. You are basically only limited by the quality of the optics and how much patience you have. I see no reason why you couldn't produce the same quality photo with a Pocophone as with a high-end dSLR (if we ignore the difference in a resolution) if you are willing to make and stack enough exposures. The lens is actually better than most kit dSLR lenses.
RAW is a complete game-changer, for static subjects. It's not that you can get a slightly better quality but that you can get as good a quality (signal-to-noise, dynamic range) as you want.

For comparison, here is a single exposure from the sequence:
