I'm curious about the thickness. Is there room to retrofit a QI-charger module?

What is placed beneath the hump on top of the phone?

What I already tried/found out:

1. The battery seems to be charged, it has 3.82 V.
2. The battery has 4 pins, the two non-supply pins seem to have no electrical connection (Megaohms resistance) to each other, so it doesn’t seem to be a thermistor (or a broken one). I suppose it’s more likely the battery has an internal protection circuit and this is a communication port.
3. I can’t even get into recovery, it immediately goes to the battery low screen and turns off. Hard reset is impossible.
4. Charging port looks good
5. Running the phone via cable and without battery does not work. It very shortly turns on the screen and immediately turns off again.

Since replacement batteries are a bit expensive for this phone I’m wondering if replacing the battery could likely fix this or if the battery is okay and the problem lies with the phone (meaning I likely can’t fix it).

Anyone had a similar problem? Anything else I could try?

Edit 1 week later: Directly supplying the phone battery plugs with power from a lab supply did not work. Charging the battery outside of the phone worked but didn’t help with the issue. A new battery did not fix the issue.

Edit 2: I found someone else who bought the phone from me and promised to tell me the fix in case they successfully repair it.

In case they tell me I will post the answer here.

Hoping to place an order for the repair tools and any extra supplies (suggestions?), as well as the replacement ribbon charge port itself need for this today.

One more question—I've searched but this isn't my area of knowledge obviously, do we have to replace the whole ribbon or is there a way to just do the little metal charger port piece and reconnect it? Upon search for the replacement port the only thing coming up for it is the whole ribbon, wasn't sure if maybe there is a site for these specific things and I just don't know it.

Thanks for any help in this matter.

Does anyone know how to replace the headphone dust cover on the Cat S61?

Mine broke off today, I can source a replacement but so far have been unable to find out to actually fit it to the phone.

Thanks for taking the time to read/respond to this for me.

Translation Slovak → English

Why doesn't it turn on when I charge it even when I hold the power button

What should I do if my phone won't turn on when I charge it, it won't charge and won't turn on when I hold the power button.
