turn on low battery notification
My daughter gave me her old iPhone 6. My old phone 6 is also an iPhone 6 and always had a reminder pop up when my battery got down to 20%. When we transferred all of my info from my old iPhone to her old iPhone, I no longer get that notification and I want to know how to turn it back on. I find it very helpful because otherwise the phone just shuts down with no warning when the battery gets too low. The only info I’ve been able to find on Apple’s support is how to turn that notification off, not how to turn it back on. Please help!
iPhone 6, 12
