I have a (previouslypreviously broken) iPhone 5C5c that I removed the offending parts from- the. The screen was shattered beyond repair, and the battery was in pretty bad condition. I'm planning to buy some new parts and repair it, but I don't want to spend around $100 and find out that other parts are broken and it's non-salvageable.
Is there a way to test the phone, maybe by making it ring or vibrate, without a battery or a screen?
update: It works, it's charging and vibrating, but it seems to be trying to notify me of something important, as it is vibrating every 3 seconds. is this normal or what
