Why would an iPhone battery suddenly drop to zero when it was at 40% right before?
I have a question about my iPhone battery. Why would it suddenly drop to zero when it was at 40% right before?
There could be several reasons for that. One possibility is that there could be a software issue causing the battery to drain faster than usual. Another possibility is that the battery itself could be damaged. Have you tried resetting your iPhone or getting the battery checked by a professional?
