Very slow charging with new battery
I have just replaced my battery with an iFixit battery and it charges at around 10 watts whereas as previously it would charge much faster. I have reset NVRAM and SMC and calibrated the battery.
Have I received a defective battery?
I have reset the SMC again after waiting for the battery to discharge completely and it is charging faster but the speed is steadily going down. At first it was 30 watts, it’s now at 21.
I have charged the battery to 100% and unplugged it and 5 mins after, the battery was down to 10 percent.
The “Design Capacity” is also dropping.
