Arrow [Q] What does this flex cable connect?

Can someone tell me what this flex cable is connecting?

My phone would sometimes spontanously freeze and switch off, showing the 3 red leds and just stops responding. It won't even take a charge. Usually the battery is at 60% when the phone dies, and sometimes it shows a constant RED led.
The back cover is loose (but has enough adhesive to actually stick reasonably, takes little force to open it up), so I pressed that connector with medium force. The next thing that happened, is that the phone responded to the charger, booted to the "charging state", where it shows the battery state and so on (which it shows it's approx on 60%.

Or could it be that I press something else, which causes my phone to work properly again?

Thanks/Hvala!

But do you know what could be faulty on this specific point, which causes my phone to not charge? Can I find somewhere a complete guide to the disassembly and identification of all parts? It would make it alot easier for me . My phone is running again, going strong at 65% and still discharging for the last 3 hours. I'm logging the microVolts, temperature and other stats from the battery to see if it's the battery causing the malfunction, which I doubt.

Anyway, there should be something. By the way, prior to the issues, my phone dropped flat on the screen on tiles, about 1 meter high. So most likely, there is something loose/messed up. But I don't know what causes the entire system to flash the LED 3 times, saying that the battery is drained, yet after pressing on this point, immediately start up while on the charger.
