Battery drains from 40 to 25% and than in a few seconds to 1%-0%
Hello, I have problem with my iPhone 8 battery. Since housing and charging port replacement, my iPhone starts to turn off randomly, even if battery percentage was 70%. I thought, that an original battery was damaged during the process (which surely was), so I decided to buy a new one. After replacement, everything seems to be OK, phone works perfectly at 100-50%, but around 50%, battery very fast drops to 40, then drops to 25% in a few seconds and then drops to 1% and 0%. Should I try to replace battery again? Where could be the problem?[br] Thank you for all your answers.
