Other Timed charging to maintain battery health?

FYI, when setting up a personal automation based on battery percentage, I’d recommend setting up another one with a higher percentage. I setup an automation to turn off smart plug when >80% but there must have been a network hiccup since it didn’t turn off and then phone charged to 100% (I know, OMG! :cool:). I setup another automation for >85% as a backup.

And, yes, these setups are overthinking things but, for me, I sell my phone every year and numerous people backed away because my 1 year old 11 Pro that was at 91% battery health, even though I had no concerns with battery life. I resorted to selling it for $50 less than my asking price after going back and forth on just the battery health.
 
So let me get this straight. To preserve the battery you live as if the battery has already lost 40% capacity (keeping it between 20%-80%) to keep it from having 5% less when you get rid of it. WHAT?

Just having fun with y'all, I have a plug timer, like the Christmas light ones that charges 90 min in the middle of the night, wired 5w. My usage is low where I don't need to charge during the day so its set and forget. At 3 years this cuts down on the iPhone being on trickle charge at 100% for ~320 days. Phones get pass down within the family so this one time set up seems worth it even if minimal, perhaps not minimal as we know laptops always on the charger at 100% take a hit on battery life.

I’d be curious to know why my SE1 is still at 95% after two-plus years although it is outside the 20-80% safe range quite often.

EDIT: This is not at all to disparage the efforts in this thread. I’m just as curious as you how battery health really works.

Just got a 12 Pro and looks like a good base to start with. Had a X and tried wireless charging for a year that put a beating on the battery health. So now only 5W overnight for me.

Yeah, it came as a surprise to me since I simply charged daily overnight. I didn't care or have any concerns with the battery health, until it became a concern for everyone else when selling it...

OP,

Create your own Automation in Shortcuts and have the phone audibly alert you when it is done charging. That is a to easier than what you are thinking of.

That won't work since it will be when I am sleeping. That's driving the need for automation.

Nice, that 95% is a calculated so you could of had a base of over 100% starting. There are some members here with still 100% after a year or two with some battery management. Usage is big factor also.

I think what happens in those those states (0-20 and 80-100) plays a big part. If someone plays video games on the charger at 100% that is worse than playing in the 20-80 because its at the extreme state of charge at an elevated heat. So I think time and heat in those areas or states are battery killers more than just operating in those ranges in cooler temps. For typical usage (those who don't need to charge during the day and have more than 20% at night), don't think it will matter much, charge over night with 5W charger and you are good to go.

It did on mine as well, I had to drain my battery to below 5% and do a full charge a couple of time and display range starting to coming back and now i charge it to 90% all time

So even when it’s sitting in your house it’s at 90% state of charge? I’m at this point ok with a screwed up bms until I can continue commuting regularly, which is 90 miles round trip with my charging typically set to finish at 8am at 90% state of charge. My old range was 324 miles at 100% state of charge (model 3 long range). I did a road trip to sequoia a few weeks ago and my max range was 307 miles so my bms is definitely screwed up because I was charging to 50% for months since I’ve been working at home.

so fast wireless charging cable is bad?

You know I can’t say yes to this. At this point it is anecdotal evidence and based in each of our personal experience. While I had negative battery effect on wireless charging others report they had no issues. Some fast charge and have no problem, I experience higher degradation so eh whatever. I think do what you feel comfortable with. I plan to do 5w overnight charging on my new 12 max. And sporadic fast charging 30wattt anker PD. I’m will also not use my usbc fast charger in my 2 cars so I have to order new cables and avoid fast charging in my car.
It would be interesting to revisit this thread in November 2021 and report our experience.

Yes 90%
I drive it less but still use it daily
 
I have to admit you almost got me because the idea of the automation to solve this "problem" was intriguing.

But in the end, no, because it's just not necessary. The battery doesn't need to be coddled. It will work just fine for as long as the average time a user keeps a phone, and then can be replaced if kept longer or traded in and never worried about again.

One of the worst things a user can be aware of are the mechanics of lithium ion battery health, IMHO.

So, what I did there is that I created another automation to turn on the outlet when my iPhone battery reaches below 75% so that the charging brick would be on and ready to charge whenever I need to use it again.

this workaround is really great and absolutely ridiculous that we have to go to these lengths to properly take care of a battery.

The ideal charge level to maintain a li-ion battery to degrade as slow as possible is to keep it between 65%-75%

Because this is for knowledge and curiosity, does anyone know what battery usage impact there is from Shortcut personal automations?
 
If this is just a curiosity, fine. But I find that a lot of phone geeks DO worry about battery longevity. It's funny though, as most of these people will replace their phones WAY before the battery ever goes bad.

I'd be willing to say most people who frequent forums such as this one will replace their phones FAR before the battery ever goes bad!

These days with hardware being more mature and robust it seems that more and more people are keeping their devices longer (and in various ways using them more and more).
 
The whole battery life thing is weird. I’ve got a original SE I used for at least 2 years and I checked it the other day and its got 98% battery life left. I would charge it numerous times during the day and plug it in every night. No worries. Xs I had for two years was down to 86%. Only difference was I charged it wirelessly every night.

I had an iphone 5c for 8 years. The only reason I got rid of it was because stuff just wasn't updating anymore.
I've also had a Macbook Pro now since 2012. I'm using it right now. The battery's cycle count is at 580 which implies that it may last another 7 or 8 years.

I recently setup a Homekit smart plug that my wireless charger is plugged into. I then setup a personal automation/shortcut to turn the smart plug off when the battery charge gets to 80%. This can be done in the Shortcuts app. It’s working great so far.

I had an 11 Pro that ended up at 91% battery health after a year. I had no issues with battery life but this turned off numerous buyers when I sold it before getting my 12. Hopefully this measure will keep the battery health up for when I sell it next year.

I've had my iPhone 11 for little over a year using optimized battery setting and charging on Qi charger and my battery today is still at 100% so none of this hoopla for me.

Let me repeat for the newly joined that I started this thread based on curiosity, not worry. I also enjoy the experimentation and implementation aspects of doing this. It is FUN to try this and see what happens.

Let me periodically re-up this previous post of mine.
