Chosen Solution

Recently purchased an iPhone 5s. Had it plugged into my Mac for about the last 40 minutes and it’s showing the red battery on the screen. When I unplug, it says to plug in the lightning cable. I’ve opened the phone and unplugged the battery connector and plugged it back in. Not sure if there are any solutions I can try, just desperate for it to work. Thanks, Sam <3

Apparently, a battery replacement will fix this issue. Is that correct?
