    Mid 2012 MacBook Air - Trick SMC or logic board to use any custom battery. - 820-3209

    Hello, I'm wondering if there are some ways to hard wire or mod the logic board of a 13" Mid 2012 MacBook Air (820-3209) to boot from any custom made battery. Basically tricking the SMC to not validate the battery. I do not want to use SMC bypass since that will defeat the purpose and the...

    2017 MBP 13" Battery Draining/Not Sleeping When Lid Shut

    I've noticed this to varying degrees over the past few months: I would close my notebook, place it in its case, and keep it in my bag to travel to or from work. I may not use it for a day or two. When I wanted to resume work on the machine, let's say 36 hours later, the battery is depleted and I...

It has the black...

    Why did my MacBook came from 100% to 4% unused on a plane?

    I had my MacBook Air 2018 in a backpack on two flights, I haven't been using it for about 36h. I charged it to 100% before my flight. Today I opened it and it was 4%. How did it happen? Do planes somehow make batteries drain? I haven't heard anything about it. I hope my MacBook is alright.

    iPhone iOS 13.3, High "Screen Off" time on battery while charging overnight

    Has anyone ever seen this before? While my iPhone 11 on iOS 13.3 is plugged in and charging overnight, the "Screen Off" time is basically spiked to 100% every hour that it is charging. Not sure what's going on here. I have not power cycled the phone yet but I will probably try that next.
