My battery works normal till around 50%, and and then drops to 0%
Recently, I tried repairing an old note9 i found at a garage sale. It had a swollen battery thats all. I changed it, but noticed that it works fine till around 50%. After that, it drops to around 40 or 30% and then plumets to 4 or 5%. Same thing happens if i restart the phone below 50%. While removing the battery flex cable, i used a tool with a metal end because i couldnt disconnect the cable and I saw a small spark.
Ist dies eine gute Frage?
