12 months in the past, I changed the battery in my 2017 13″ MBP with Touchbar 4 thunderbolt. I changed it with the NewerTech battery from OWC/Macsales.com. It was reporting that it wanted to get replaced and barely stored a cost.
It’s once more having cost points (though the battery well being claims to be “Regular”). When first put in, I might simply get 6+ hours of utilization on the laptop computer. Now, I am fortunate to get 3 hours.
Issues I’ve tried:
- resetting the SMC
- Disabled “handle battery longevity”
- Permitting the battery to cost to 100%, Drain to 0% (automated shutoff) – let sit for five hours. Re-charge to 100%, and let it cost for 3 hours.
This has not materially improved the battery efficiency.
I’ve seen one thing unusual – the “Battery Stage” in “Utilization Historical past” will bounce from ~25% to 100% when charging. I ponder if the battery actually solely has ~30% of it is capability, regardless of MacOS pondering it has extra.
Does anybody have any concept whats occurring? I am nervous that the laptop computer itself is broken and damages batteries, or if i’ve simply gotten actually unfortunate.
Thanks!
