I personal a Mid 2011 Macbook Air 13″. It’s working macOS Mojave 10.14.6.
I changed the battery as soon as with a battery bought from Amazon.
coconutBattery is reporting, as of proper now, as having:
- Full Cost Capability: 7121 mAh
- Design Capability: 7200 mAh
- Manufacture Date: 12/12/2016
- Cycle Depend: 68
- battery standing: Good
The issue is that it drains extraordinarily quick. I’ve tried Ubuntu on it as properly, no luck. Even the earlier model of macOS on this technique (Excessive Sierra). I did a full battery drain, charged to 100% and nonetheless no luck.
Whereas turned off, I held down Shift + Management + Choice + energy button. I held it for about 10+ seconds, I launch and the MagSafe LED turned from orange to inexperienced for a couple of seconds, then again to orange.
I believed it was the battery, so I ordered one other battery from Amazon. The identical subject.
That is making me consider that perhaps some form of connection is unhealthy on the battery, or the Mac is having some unusual subject. I do know it is an previous laptop computer, nevertheless it’s been one in all my favorites and I carry it round each time I’m in an space the place it could possibly be stolen. The substitute battery from iFixit is about $70, however I do not need to cope with it if it is the Mac.
Any concepts what I can attempt? I bear in mind the battery life was wonderful method again once I purchased it.
