    MBP 1,1-10,2 Getting System Management Controller, Core 2 Duo MacBooks, and Charge Limiter to play nice together?

    So this is a total long shot, and it goes well beyond my limited wheelhouse of making un[der]documented things work nicely. It also means inviting those cosy with under-bonnet stuff to chime in. The magnificent open-source utility, Charge Limiter (which does what other, more proprietary battery...

    Battery Myths

    Hi guys, I heard two opinions on how to conserve battery health and cycle count. A: Charge until 80% and unplugged it and charge again when battery reaches 20%. B: Charge until 100% and charge again when it reaches 20 or 30%. I heard many influencers recommend us to charge only to 80% to...

    Currently, I charge my laptop about twice a day and try to keep the battery level between 20% and 80%. Since I bought it on April 2nd, I've accumulated 12 charge cycles.

    StandBy Mode & Battery Health

    While I like the idea of StandBy mode on the phone, it seems at odds with battery health. I was under the impression that leaving a phone charging for long periods of time can contribute to quicker degradation of the battery, so with having the phone needing to be charging for StandBy mode to...

    iOS 17 Has Made My iPhone 13 Sluggish

    Well, I didn’t see this coming. Last week, I installed iOS 17 on my iPhone 13, and now my experience is a lot more crappier than expected. First, the battery life. Of course, I was expecting some battery drain with this update, as I have experienced with iOS 16 (I had to learn that the hard...

    Unsolved PowerPC mysteries: The “well, that’s not swell” edition

    This is a terrible question. I’m neither an electrical engineer nor a chemist, which makes this all the more clumsy of me for asking it. Every swelling lithium battery I’ve experienced over the years has come from Intel Macs and other devices (such as phones and other makers’ laptops). The odd...

    Is Apple Manipulating Battery Health?

    I have seen mention of this topic on iPhones, but I wonder if the battery health figure is reliable on the Watch. My S4 (used almost daily for close to four years) has seen a slow but steady decline in battery health but stayed at a constant 87% since the last watchOS update (os 8). However...

    When does Apple replace iPhone batteries for free?

    On Apple’s website, it says “If your iPhone is covered by warranty, AppleCare+, or consumer law, we'll replace your battery at no charge.”. However, in their legal page, it says batteries are not covered under warranty. I have heard of people getting free replacements if the battery health is...

    iPhone 13 mini Should We Move Away from Wireless Charging for the Sake of Battery Health?

    I’m incredibly close to keeping iPhone 13 Mini, which has only one true drawback compared to the rest of the line: reduced battery life due to the smaller battery. I’ve been reading that wireless charging, and fast charging in particular, degrades the battery more quickly. This may not bother...

    14" MBP battery already dropped to 99%

    It's only got 21 cycles on it and 2 of them were already there when I got it. Coconut battery fluctuates between 95 and 97 but the system report now shows 99%. How could a brand new laptop battery drop that quickly with only 21 cycles? Anyone else seeing this?
