My A07 has been having a super fast charging issue since a week ago.my phone is fully updated.When my battery is at 30s% thats when charging issue comes up.so,when i plug my phone to the charger at 30s% battery,it shows as super fast charging but it charges at avarage,normal speed.so,it take like 30 mins to charge 10-15% battery.still most of the time it says super fast charging,but sometimes after like 5 minutes of being plugged to the charger as super fast charging,it drops to just "charging" and the predicted time become hours.if i unplug my charger and replug rightaway it gets fixed and charges at super fast charging speed.also,i don't need to unplug and replug,even if I restart my phone while the charger is plugged,it still get fixed.also if my battery is at 40s,50s or above,this issue doesn't happen and charges without issues.I haven't tested at 20s% battery.
This doesn’t look like a hardware fault. What you’re experiencing is most likely a software/charging optimization glitch after the recent update. When the battery is around the low-30% range, the system sometimes mismanages charging negotiation, so it shows “Super fast charging” but actually limits the speed or drops back to normal charging. That’s why unplugging/replugging the charger or restarting the phone immediately fixes it — it forces the charging protocol to re-initialize. Since it doesn’t happen above 40–50%, your charger and cable are working fine. For now, just keep using an original charger and cable, avoid charging while the phone is hot, and wait for the next software patch, as this is something Samsung usually fixes with an update rather than a hardware repair.
