iPhone X restarts randomly after screen and battery replacement

Here’s my story:


I dropped my iPhone X a few weeks back (didn’t crack the screen, just had a black spot on the top right corner), following which I gave it to a reputed 3rd party repair centre in India for a screen replacement and a battery change (as I had gone down to 80% health in 3.5 years).


They replaced the screen and put in a new battery. After this my phone started restarting at around 50% battery and dropped down to 10%.


The phone would then restart again after a while and restore back to the level it restarted at.


The store replaced the new battery again and the phone worked fine for a week or so. Now I’m having the same problem again.


Any idea whether this is due to a flex cable problem or is it the battery itself or a motherboard issue?

Found this in the logs, in case someone can make head or tail of it.
