There could be so many causes of slow charge or not charging on the Infinix Hot Note X551. The phone comes with a flash charge feature this makes charging the 4000mAh Battery extra-ordinary fast and still last for 7 hours.
HOW TO FIX INFINIX HOT NOTE X551 CHARGING PROBLEM
First thing you need to do is check if your charge is not burnt or affected by high electricity voltage. You can do this by smelling it, if you have a blocked nostrils give someone else to passive it for you.
If the charger adapter is okay then you need to check your USB Cable. We both know the Infinix USB Cable that comes with the phone is of low quality. Replace it with another cable.
In my case, the USB Cable was faulty so i was getting a slow charge instead of “Flash Charge” after trying out with another cable i got back my quick charge.
If all of this options does not work you might need to restart your phone. Even after restarting the phone it’s still the same. You need to visit an engineer who’s skilled at phone repairs he might change or repair the charging port to get it working again.
Conclusion, cases like this should be handled with care as your Infinix Hot Note USB/Charging Port is the door to reviving your phone in any case of software related issue. I strongly advice you take your devices to CarlCare for repairs even if you are no longer covered by warranty your phone will still be taken good care of.
