I've been facing this issue since last 6 months and also changed the charging chip too. Still it's not quick charging. Please anybody help me with this as this is getting on my nerve.
Case 1- Are u using stock charger if yes.. then plz check any other device with same stock charger if it gets charged
Also check ur charging cable weather it is damaged or not by using it with other fast charging devices
If any other devices gets charged with ur stock charger kindly visit service centre as it may be hardware issue
N if those devices doesnt charge via stock charger n cable than try changing ur stock fast charger and cable and then check if ur device gets charged
Case 2 - As u described that u changed ur charging chip and still u are facing the issue than it may still be hardware issue as it may be some chip fitting problem where u have changed it earlier kindly get it checked again
Thank you for the help! I'll keep that in mind
