Chosen Solution

I have changed the device screen. Indeed, I disconnected the battery cable after installation. The phone works, but it restarts itself every 5-7 minutes and the charge rate is 2%. I have checked the battery cable and it’s installed properly. I also checked the battery ratios in settings and it was unknown instead of numbers it shows to me (-) although the battery was fine before the screen was broken and also when I tested the screen in the middle of the installationI apologize for the language, I use google translate Is the problem with the cable,or the battery?

  • The charger cord I use is from Anker

If your phone cannot read the battery information it will keep restarting. The most common cause for this is a faulty battery. Replace the battery and see if it still has the same symptoms if it does it will be a problem with either the battery connector or one of the charging IC’s most likely Tigris.
