I took apart my phone because I had gotten a headphone tip stuck in it. I have no experience on devices but i watched a video on how to disassemble. Well when I got to the battery plug I used my tweezers to unplug it and saw a tiny spark come from it… I was sure I shorted it but I put my phone back together and sure enough it wont turn on, is there any recovery from this?
The first thing to check is the condition of the battery. If you’re lucky, you may have only shorted the gas gauge circuitry on the battery (there is a circuit board inside the black wrapping). The way to test for this is to either replace the battery or if you have access to a multimeter, probe the battery connector to see if it shows any voltage. If it shows 0V, then the battery circuit was probably damaged. If it shows something like 3 - 4.2V, then the battery is fine and you probably blew something on the logic board. That would require a micro-soldering repair.
You can try a new battery, but if that doesn’t work you phone is pretty much a paper weight now.
just plug it in, you’ll be fine. You probably set off the battery protection circuit, but if you plug the device in, that will wake up the battery and the phone will work if there is no other damage.
