Why Your Phone Charges Slowly (And How to Fix It)

Check the cable and adapter first

Cables fail far more often than phones do. Try a different, certified cable and a charger that supports your phone’s fast-charge standard before assuming anything is broken.

Clean the port

Pocket lint compacts at the bottom of the charging port and stops the connector from seating fully. This is the most common cause we see, and it is a five-minute fix.

Look at background activity

A phone that is downloading updates or running GPS while charging can consume power almost as fast as it takes it in.

Then suspect the battery

If none of the above helps and battery health is under 80 percent, the cell can no longer accept a fast charge. That is the point to replace it.
