Battery draining very fast
My macbook is 254 days old & I’m experiencing severe battery drain , close to 20% or more dropping in just about an hour with light web browsing. I have attached my battery health status, could anyone please help me know wether this is normal. I do not overcharge my mac or drain it to zero .
Assuming the battery is about 11V and you are using 10W of power (approximately what you show) this would be a drain of 909 maH. Since the battery is shown to have a full capacity of 4752 maH you would discharge the battery 909/4752 = 19.1% in an hour. What you see seems correct and not severe unless your statement is not clear.

Besides the charger, do you have a dongle or hub device connected? If so disconnect them and only directly power your system via the charger.
Did you review Activity Monitor to see if you have a process consuming resources?
