Another issue you may see over time is that your phone no longer fast charges the way it once did. The first thing to check if this is happening is your charging cable and charging block. Try switching them out with another setup to see if fast charging. Next, check your charging port. This problem is often evidenced by a wiggling charging cable; a dirty charging port will slow down your devices' ability to reach full battery capacity. Use a flashlight to look in the charging port for dust, lint, and other debris. Be mindful before cleaning your charging port. Many models have delicate prongs that, if broken, can cause even more issues. Lastly, you may have failing hardware. If the charging port or Sub-PBA has gone bad, you'll need to have it replaced by a professional.
