Chosen Solution
I changed the battery and screen a year ago. I broke the screen (again!) and it worked well - I was able to plug and recharge the battery. But I let the battery completely discharge yesterday and since then I cannot recharge the phone. If I plug the phone, I see the design of the battery with 1 small red line but it doesn’t charge. I can charge the battery again but I suspect that it’s not only the battery. What do you recommend changing?
Connect the charge cable and once the battery logo appears press and hold power and volume down together for 20 to 30 seconds or until the apple logo appears. If the phone turns on it sounds like you need a new battery.
