It may give an indication of whether the battery is due replacement or not. A MacBook battery is good for 1000 cycles, so compare the reading to that number and see where you are. If the warning does reappear, check to see how many cycles it should have left in it. You will find any customizations you may have made will be reset back to default but hopefully the Service Battery Warning should finally disappear.

Turn on the MacBook and boot as normal.

Press left Shift + Ctrl + Option + the power button all at once and hold for a couple of seconds.

It also resets any hardware preferences you made since using the laptop. This is a process of last resort as it isn’t often the cause of the Service Battery Warning. If the warning reappears, your only option is to reset SMC, just in case. The Service Battery Warning should now go away. This is calibrating the battery and works much like a factory reset does for the laptop. Leave the laptop empty for a couple of hours.

This way, you'll know if it's worth buying a new one to enjoy a real portable notebook. It will tell you if it is damaged or not and will compare its performance with the performance of the first day. Allow the battery to completely run out ignoring any low power warnings. CoconutBattery is a lite application that keeps an eye on the battery status and warns you in case it is too low.Unplug from the mains and leave the computer running overnight or while working.Charge your laptop to 100% and leave it running for an hour or two.Update: still gobbles up power when playing music on YouTube (Tangerine Dream fyi). My only quibble with the Retina display is that the brightness gets too dark when lowering it just a few notches, the scale is a bit extreme to me. Remember when notebooks barely got 2 hours battery life, they were fun times! Anyway, it's all good, everything is perfect. Disappointing the Air has taken a small backward step in battery to take a small forward step to catch up with the Pro, but it's a small price to pay.

I'm probably going to get 9-10 hours from a full charge if just have the barest basics running. The 2020 MacBook Airs aren't going to get the 12 hours my 2014 model got, unless you lower everything to the bare minimum. It's less than a week old and is still having odd bursts where it loses several percentage quickly all of a sudden when web browsing, but other than that it looks okay. The battery is tracking a lot better out of the box compared to the first one, so I'm a happy camper. UPDATE: store did a straight swap for a new MacBook. My old 2014 MacBook Air was still getting 8 hours of continuous video play up until its untimely death a couple months ago, so I'm a bit mindboggled with what's going on here. Will this take a couple of weeks to balance out with the SSD? I'm in Melbourne and in lockdown, so taking it back to the point of purchase or to an Apple store is out of the question for another month.Įdit: Battery was 98% 2 hours and 15 minutes ago and is now at 56%.Īny help appreciated.

I've run it to low, shut down for a few hours, then charged it to 100%, but still no luck. I've done the basics, turning off features I don't need or use. There's no way it should be draining this quickly. I watched Akira Kurosawa's Seven Samurai on Apple TV, which I downloaded, and I lost about 30-40% battery life each hour.

I bought my 2020 MacBook Air (i5, 512gb SSD) a week ago, and I'm losing about 20-25% battery life per hour for general web browsing. Apologies if this is a common question, but I need to ask in case I've missed something obvious. I've done some reading here and elsewhere to help troubleshoot my battery life, but no luck.
