MacBook Battery Says "Service Recommended"
MacBook Air / MacBook Pro • Battery shows Service Recommended
Quick Answer
Service Recommended means macOS has measured your battery's maximum capacity below about 80 percent, or it has detected a fault. The Mac still works, but runtime drops and sudden shutdowns become more likely. Check System Settings, then Battery, then Battery Health. If capacity is low or the warning stays after a restart, a battery replacement is the fix.
Possible Causes
Normal battery wear
CommonLithium-ion batteries lose capacity with every charge cycle. Most MacBook batteries reach the Service Recommended point after several hundred to around 1,000 cycles.
Heat exposure
CommonLeaving a MacBook in a hot car or running it hard on a soft surface speeds up battery aging.
Battery calibration glitch
ModerateOccasionally the battery gauge reports wrongly after a macOS update. A restart and a full charge cycle can clear a false warning.
Swollen battery cell
Less commonA cell that is swelling can trigger the warning. Signs include a trackpad that will not click or a bottom case that rocks on a flat table.
What You Can Try at Home
Check battery health
Open System Settings, then Battery, then click the info button next to Battery Health. Note the maximum capacity percentage.
Check the cycle count
Hold Option, click the Apple menu, choose System Information, then Power. The cycle count shows how worn the battery is.
Restart and do one full charge
Restart the Mac, charge it to 100 percent, then use it normally. If the warning was a gauge glitch, it may clear.
Look for swelling
If the trackpad is hard to click or the case bulges, stop using the Mac on battery and get it checked. A swollen battery is a safety issue.
When to Get Professional Help
If the warning stays after a restart, the maximum capacity is under 80 percent, or you see any sign of swelling, it is time for a new battery. Do not try to pry out a MacBook battery yourself. They are glued in and puncturing a cell can cause a fire.
