Question Why is my mac's battery draining so fast?

[dhawalpandey2004]

I own a Macbook Air 11 inch mid 2011(4,1). So, I have been noticing that recently my mac's battery drains faster than normal. It also has the service battery warning on it. I installed coconut battery and it says that I have completed 374 charge cycles and my full charge capacity is 2538 mAh while the design capacity is 5200 mAh. I have tried battery calibration but it didn't fix the problem. What do I do?

Replace the battery. That should solve the issue.

I agree with COLGeek. If the battery has gone through 374 charge cycles and the full charge capacity is less than half the design, it should really be replaced.

some application may be consuming too much battery, look for some background processes too, if there isn't any high power consumption, try to get your battery replaced maybe the cells are weak as it is 2011 model.
