MacBook Air M5 battery charges slowly

Slow charging on MacBook Air M5: 6 months old, 88 cycles, 98% battery capacity; 35 watt charger (came in the box) with nothing else connected; at 52%, battery settings says it will take 2 hours 10 minutes until charged to 100% with optimized battery charging off and low power mode on.


I always have the charging limit set to 85%, low power mode on, and optimized charging on - turned it off to make this post, to see how long it would take to charge to 100% with optimized charging off.


  1. Is this normal? Charging feels very slow. 2. If not normal, can it be fixed by replacing the battery, or something else? 3. I have applecare+.

Troubleshooting Lagging Mac Charge:

It can occur during to a large number of possible issues. But, with Optimized Charging being off, then this is of suspicion. So, see about troubleshooting this on your own. If of no success, then take this in for a Genius Bar Appointment at your Local Apple Store.


Refer to the following....


A. Reset the SMC and your NVRAM:

(Applies to Intel-Based Macs Only): Sometimes when changes are made to the system(i.e. Updates), system configurations (i.e. for Power) become manipulated, technically. So, reset the SMC and NVRAM. Try performing each thrice. It may take sometime, being certain you have the time to perform these resets.


B. Try a New Charger:


C. A Few Links to Refer to for Power:
