Regarding the strictness on getting a free battery replacement for iPhone X/XS/XS Max, there is a design flaw on these 3 sets. If you notice the camera lens at the back of these 3 sets, the microphone hole is cut out at the same āsapphire glassā where they put the 2 camera modules.
Iāve had dust issues with my previous iPhone. On display sets at iStudio and Apple Orchard Iāve also noticed. With naked eye itās quite hard but look under direct sunlight or table lamp or using a watch loupe, certainly you will spot dust specks either at the TOP or bottom camera module.
And this is not an insolated problem.

Google and youāll find that there are lotsa links all over the world on this.
This dust problem is not as widespread on other iPhone models (iPhone XR/8/7) whereby they separate the microphone hole with the cam lens cover. Not that dust wouldnāt enter these models, but not as widespread as X/XS/XS Max.
I went to Apple Orchard for this problem for my XS Max couple of months back. Technician did manage to remove the dust speck at the TOP camera module, but new smaller dust specks appeared at the bottom of the cam lens module. Hence I requested for them to remove again. 2nd time round they couldnāt remove totally the dust specks. Total 30mins x 2.
They gave me 2 options: either 1) live with it (which wouldnāt affect pictures taken) or 2) they give me a 1-1 phone replacement. I deduced the tech wouldnāt wanna waste another 30 mins to dismantle and remove dust, and seal back the iPhone XS Max. If you watch the dismantling videos, itās actually quite a hassle to get to the camera module potion.
That time my battery was 100% health. So I opted for option 1, till I sold it and was thrilled that engineers for iPhone 11 Pro/Max noticed this dust flaw, and separated the camera enclosure modules outside of the microphone hole module.
Till now, I also quite puzzled how on earth could dust specks enter an IP68 phone. Itās the highest level given for a dust/water proof electronics.
Curiosity killed the cat, and so I began to research on YouTube with regards to this dust issue. There are lots of dismantling videos whereby youāll see that underneath the microphone black netting, dust certainly can enter very easily to the cam module. Once dust enters itāll just stuck there for when thereās no air inside, the dust canāt be shaken or move.
I can only think of incidents whereby if you apply powder in a room near aircon with your fan speed turned on high, or any table fan in your room, pls make sure your iPhone (especially the 3 models that I mentioned) is far away and donāt put the camera lens facing upwards.
Powder dust particles are much smaller than the black netting hole.
The battery is above 80% and you canāt get a free battery replacement? You may like to scrutinise your camera lens again.
