I have a Macbook Air M2 device.October September 29th, I bought it and used it until October 15th and I still use it.idid a battery cycle5times.during the entire time I used it, I never used its charge up to 0%.while using my laptop normally today, my charge was 4%.Then I closed the covernormally, and when I opened it touse it again, the screen showed "Plug in to charge". I plugged it in to charge andturned it on, and the battery wasstill at 4%.Afterplugging it in, it continuedcharging. thenmy chargewent down to 4% again, but this time it didn't turn off and went down to 3% and 2%.Is it normal for my laptop to turn off when the charge is at 4%? Do I need to have it repaired, or is it asoftware issue?

So have you tried using a different charger and cable? If the charger is pugged in yet the charge level continues to drop that indicates either a bad charging block and/or bad cable, or the MacBook does indeed need to be examined and diagnosed for the issue.


From whom did you buy your M2 MacBook Air? Apple discontinued sales a long time ago so no new M2 are available through authorized reseller channels.

Well I think I understand now. You should never EVER let a battery discharge anywhere near 0%. You should never EVER let a charge get so low that the device shuts itself off. That’s a battery killer for sure. Why are you doing this? It’s destructive. Never let a modern Li-Ion battery completely discharge to 0%.


My personal recommendation is to charge when the battery gets to 20%

Check the condition of your Mac laptop’s battery - Apple Support


If battery health is 80% or lower it’s entirely possible you need a new battery. Your MacBook is exhibiting the classic signs of the battery being near end-of-life. As you should know batteries are consumable, meaning they degrade over time and don't last forever. If your MacBook is over three years old it may be time to replace the battery.

hi, I bought this macbook m2 from an official site that has the apple premium education partner label. the warranty lasts until 2028. It is charging while plugged in. There is no problem with the cable. It can charge up to 100%. My only problem is why does the device turn off at 4% instead of 0%?
Note: I just charged the device a little to try it out and used it again, and this time it turned off at 1% and I'm charging it smoothly now (my own guess is that the laptop doesn't turn off when typing 0%, I think)

The M2 MBAirs were discontinued in March 2025 according to the MacTracker app. That means either you received a brand new laptop which has been sitting for a year & a half and likely had its battery drain to 0% charge which can cause permanent damage to the battery.....or, you received a used laptop which may have received a third party replacement battery which is bad. The quality of third party Lithium batteries is quite poor even when purchased from a reputable vendor.


Either way, I would return it for a full refund.

I don't know, this only happened once, and when I tried again, the battery dropped to 1% and it turned off normally. I'm sure the device is brand new, and the seller was an official Apple-affiliated site. I hope I won't encounter any other problems. Thanks for your reply.

Digital estimates (remaining power) of analog processes (battery charge) are not always going to be totally accurate, and battery usage habits trending toward “battery maxing” aren’t a practice I’d usually recommend.
