> the best solution is slow charging, for which a low-power charger from your old feature phone is ideal. These devices offer a small power output of 2–5 W, stretching the charging process to 5–7 hours depending on the adapter's power and the battery capacity. This way, your phone's battery charges under the best conditions, minimizing degradation
I've been charging my iPhone this way since the iPhone 4 (trickle charging overnight) and have noticed zero improvement in battery degradation performance vs. fast charging.
As a current example, my iPhone 15 Pro, purchased a month after launch, is at 85% capacity.
- SietrixDev 2y agoMy iPhone 15 Pro Max, first use on September 2023 is at 98% capacity. Charged mostly on a wireless charger and the charge limit set to 80%.
- LUmBULtERA 2y agoIphone 15 Pro here, first use Nov 2023, is at 94% capacity. Mostly wireless charging at 80% too. 290 cycles.
- mvkel 2y agoIf you're capping the charge to 80% always, the only beneficiary of the total capacity of the battery is the next owner. Like wrapping your furniture in plastic.
- icebergonfire 2y agoAnecdotally speaking, the 80% limit seems to be key to better battery aging long term.Anecdotally speaking, the 80% limit seems to be key to better battery aging long-term. My launch-day iPhone 15 Pro Max is at 95% battery health. That phone has had the 80% limit enabled since day one, and I very rarely have had to increase it for specific busy days. My previous iPhone 12 Pro Max very quickly descended to 88% battery health after a year. My charging habits remain the same: fast and furious Magsafe/Qi/Qi2 charging every time there is a charger nearby (remote worker, so that’s almost all the time). I do have unpleasant thoughts about the 80% battery charge limit not being available on anything older than the 15, since it turns out it can be sideloaded via Nugget and MobileGestalt manipulation. Not enough to push me away from the walled garden (these phones are aging better than my previous flagships from other ecosystems), but a reminder of the rough edges in it.
- mvkel 2y agoIt seems strange, though, that one would habitually charge to their "effective" capacity of 80% for the purpose of preserving the battery for the next owner
- calfuris 2y agoI do it for the purpose of preserving the battery for myself down the line. I'll go for a full charge if I expect to need it, but 80% is usually more than enough so why put unnecessary wear on the battery?
- mvkel 2y agoisn't that intentionally creating a lot of mental anguish every day (trying to make 80% last the full day) in exchange for just one day of simplicity at some theoretical point in the future? Feels a bit like worrying about tomorrow stealing joy from today
- maratc 2y agoHomo sapiens is a genus full of anxiety, as our ancestors who didn't "worry about tomorrow" either died from hunger, or got killed by those who did. Anxiety is an evolutionary feature.
- mvkel 2y ago> Anxiety is an evolutionary feature I used to think this way. Spent decades justifying it as a motivator. It's a trap. It made sense if you were risking your life whenever you went to get food. If you're trying to recreate those feelings by undercharging the battery of your smartphone, you're just bored
- maratc 2y agoIt doesn’t matter. You’re not trying to recreate anything. Your brain is just wired that way already. You’ve got it from your parents, who got it from their parents, all the way to our predecessors in Africa.
