Is the problem with my iPhone or the compatible magsafe qi2 charging station?

I recently purchased the Qi2 charging station for my iPhone 16 Pro. I noticed that, from time to time, the battery would disconnect during charging, waking me up at night because of the high-brightness screen (due to Standby mode being deactivated). To check, I created a short automation that logs every instance when the battery disconnects and reconnects in a note. After charging from 20% to around 90%, I extracted the note you can see in the attached photo. Is this normal? Could it be harmful to my iPhone? (I also tried charging without the MagSafe case, but the issue persists.)

Additionally, I set a charging limit at 90%, but in the morning, I always find it at 86% or 88%. Can anyone provide some answers? I would be infinitely grateful. Thank you!

Apple doesn’t say charging will stop at exactly a specific charge level. It may change slightly over or under the exact setting. This is due to multiple factors in the charging algorithm.

I wonder if the same on and off charging is because of the third party charger. I don’t use mine much, preferring a cord, but it does not start/stop all night long.

I have a Belkin Magsafe charger on my nightstand. I'm not seeing the behavior the OP reports. In addition to the possibility that there's something wrong with their charger or phone, I wonder if the issues is that their charger is Qi2.

Interestingly, I have an identical charger on my desk at work. The other day, it kept beeping as if it had been removed from charge and put back on. I restarted it and all has been good since.
