This sounds like the battery and the charger's problem to handle, not mine.

All this tech, all this automation for every damn thing, and people keep coming at me like I'm supposed to do everything manually with my fingers and eyes and maybe an alarm or something to keep me on schedule. No. Stop it.

Make the charger handle it, or shut up. Make the phone, the charger, and the battery handle it together, you know, with digital automation. Do not even mention it to me.

Just build phones with the understanding that batteries are consumables and make them easy to replace and standardized. Then swap in a new $5 battery when you need to so. Make the raw materials reclaimable too of course.

Here's my headline: Why obsessing over battery degradation is unhealthy and you should just do whatever is easiest for you

If it shouldn't be charged above 80%, then make 80% the new 100%. "But this one goes to 11"

I don't like this article because it misses some of the more important details around how to lengthen your device's life and why you may or may not want to keep your battery at a specific state of charge.

1. State of charge is pretty arbitrary, your charging circuit could charge between 3.0V and 4.2V (pretty typical), or it could charge between 3.2V and 4.0V and still show 4.0V as being 100% charge. Different chemistries can have slightly (or significant in the case of LFP) different voltages. The cynic in me wouldn't be surprised if eventually 100% becomes ~4.35V because it makes their device look better to tech reviewers, but then have it default to only charge to 4.2V because it still gives suitable device life.
2. The most important factors in how long your device's battery will last are temperature and how deeply you discharge the battery. Discharging your phone down until it dies does way more damage than keeping it charged at 100%.
3. At some point practicality comes into it, you would get even more total energy out of a cell if you kept it between 40% and 60% all the time, but obviously it isn't very practical to only use 20% of your phone's available capacity in day to day use.
4. Consider how long you are storing your device. If it is always plugged in or won't be used for months, then something like 40% to 60% would be a more suitable state of charge to keep your device at if possible. If it sits on your desk and you need to unplug it periodically and know you don't need the full charge, then sure keep it at 80%.

Personally, I don't stress about the batteries in my devices at all. I generally keep an eye on the power and plug it in when convenient, but target plugging it in before it gets too far below 50%. I've historically had almost zero issues with the batteries in my devices wearing out before I'm ready to replace it for other reasons unless it started out with marginal battery life.

Damn, some of you must have pretty chill lives if paying attention to what level your battery charge is at DAILY is something you want to add to your plates. I mean sure, if there was a setting that allowed you to have the phone automatically cut charging at 80% this might be worth thinking about. But when I charge my phone its during times when I dont have to think about it (Aka 90% of the time, when I'm asleep)

At the risk of sounding like Spinal Tap, why don't they just make the chargers stop at 80% and have the interface show 100%?

Edit: woops. Appears that's already a thing.

... Aren't devices designed to only charge the battery to 90% (and report that as 100%), because actually changing a battery to 100% is pretty harmful for it?

I plug all my devices directly into the power line pole outside; everything charges to 75000%

I live in earthquake, volcano, and tsunami territory, so I think I'll keep charging to 100% for now.

When I lived in the US and went through a hurricane, we had no power for almost 2 weeks and that stuck with me.

Leaving a battery at 100% over a long time wasn't recommended but I would imagine most devices have BMS settings to deal with this now.

not going to trust a website that makes money from repairing phones

also a lot of armchair battery scientists in here

So my battery is at 85 and Im Supposed to wake up to it at 50 instead of plugging it in? This is a engineering issue.

My Galaxy s22 has an option "battery protection" that limits my battery charging to 85%. Looks like they had a good idea there.

I'm convinced that apples laptop battery saver feature that's AI powered and decides when to charge above 80% vs just letting you set it to 80% and manually set it to 100% when needed is to cause the batteries to die sooner, because ITS GOD AWFUL AT DOING ITS JOB PROPERLY.
