iOS 16.1 new “feature” extends the insanity…

I just noticed today that yes this feature appears to be on. But yeah I never really paid attention I just plug the phone in and it's at 100% when I unplug it in the morning.
It's a good feature. Do you also use the lower power 5w charger. It helps to also extend longevity. Charging as slowly as needed is always good. I stepped down to a weaker 2.5w one since it still fully charges but even slower so it degrades even less.

I just use an old Apple charger from like three phones ago. It's not a fast charge.
 
Some quick engineering thoughts...

Isn't carbon emissions lowest for most grids during the daylight hours...when the sun is shining for solar, or the wind is blowing stronger? Isn't the cost of electricity higher during these "peak" hours? So they are reducing your carbon footprint by actually increasing the cost to charge?

I could be totally wrong here...
@OVERKILL - thoughts?
For fossil heavy grids with no nuclear or hydro, solar may drive down emissions during the day. However, demand is also highest during the day, which is what drives rates (demand). On particularly windy or sunny days with low demand it can drive rates down. However, demand is typically lowest overnight, which is why rates are lowest.
 
at 85% battery health and I could definitely tell the battery didn’t last as long
Once it gets below 90%, it can definitely be noticeable. Depending on your usage, you may have to charge it in the middle of the day to keep it at a usable level. It can drop A LOT and drop quickly.

Also when I shut off WI-FI, I want it COMPLETELY OFF NOMATTER WHERE I SHuT IT OFF.
Ditto Bluetooth

Instead of it switching on and off randomly
Sounds like you're disabling them from the "quick settings" screen or whatever it's called. If you turn those off under Settings, I've never seen them re-enable on their own.

My point is that I shouldn’t have to keep a copy of settings running to shut off Wi-Fi, what’s even the point of the drop down menu?

I actually like that option because sometimes I need to disable Wifi or Bluetooth temporarily. This way I don't have to remember to turn it back on. If you want to disable it permanently, you have to do it though the main Settings app.
 
Is there a setting to charge iPhones to 80% or some other percentage? I don’t see it in my battery settings. I have an iPhone 13 and am at 95% max capacity.

The easiest thing to do is go under settings and battery and turn on Optimized Battery Charging.

Settings>Battery> Battery Health and Charging>Optimized Battery Charging.
 
My one iPhone has a bad battery that insta crashes if I don’t immediately flip to the low power mode even with a full battery.

If they wanted to save resources perhaps allow us to PERMANENTLY SET BATTERY SAVER.

Turn them off under Settings.
 
Turn them off under Settings.
Yep have to do it every time after I plug in
Keeping a copy running ? I think you're worrying about things you don't need to worry about.


Do you read what it says when you turn off WiFi or BT from the quick menu ? It tells you it's temporary.
not getting into too many explicatives
I see no purpose in a temporary setting, I like many disagree with apples decision to add extra steps to shut off Wi-Fi

AKA the quick menu has no point in existing unless I want a flashlight which can be accessed without unlocking
 
I've read that there are a few factors that greatly affect lithium-ion batter life. I believe @JHZR2 can contribute to this discussion as well.

This is a great reference website: https://batteryuniversity.com/articles

  • The higher the voltage the more chemical degradation occurs in the battery.
  • The greater the depth of discharge the more chemical degradation occurs in the battery.
  • Heat also speeds the chemical degradation of the battery.
The number of times you charge the battery from say 35% to 45%, which is what I do, isn't a factor. If I were charging the battery from 35% to 100%, then the high voltage in the battery would be a factor.

Spot on.

A Li-ion battery is called an intercalation battery. That means that the ions physically slip in and out of a 2D graphite anode. When that happens the graphite swells 10-20%. When that happens, it starts to develop cracking and material degradation. The use of silicon dopants and other things has helped that somewhat but it still happens.

To minimize battery size, charge is typically maximized. Thus maximum swell, higher oxidative stress on the materials, higher heat due to losses as the battery charges. All negative.

In small, shallow depths of discharge, batteries can go millions of cycles. They will still naturally age, based upon exposure to temperature and other conditions. But keep that voltage, and this state of charge on a narrow band and they will last much longer.

So while the whole carbon friendly claim is a bit much (unless you have some major price difference per kW/kWh during the day), there is logic to doing this.

People are getting their panties in a bunch because they want to, not because there’s a good reason.

I’ve had that on since day 1 but looks like I lost 5% battery life in a year. I didn’t know if people were just manually charging to 50% or if there was a setting. I’m too lazy to do the manual thing and it doesn’t look like there’s a setting to set your charge percentage to. I’ll leave my optimized charging on though.

I didn’t get a bunch about the optimized charging and better battery life, especially after Apple had that class-action lawsuit loss about designed software obsolescence by essentially “throttling” older devices to get people to upgrade.

My issue was with the ESG infiltration into a device that uses just a few watts every day. If they want devices to use less power, design the device to use less power from the get-go. That’s all.

That wasn’t so much them throttling you to get you to upgrade, it was to prevent the phone just shutting off because the battery couldn’t supply enough power during high current draw periods. They should have disclosed it from the beginning but didn’t because Apple logic, and got sued for it.

Do you by chance use a wireless charger? I read that if you use a wireless charger while say streaming music/podcasts/whatever the phone draws off the battery opposed to the charger like it does if you plug it in. I used a wireless charger for most of the time I had my 12 pro max while at work where I’m almost always streaming something for 11 hours a day and my battery was down to 89% in a year. My 13 pro max is still at 100% (got it in May) but I only ever plug it in.
 
Interesting. When I reduce max capacity on my phone in Accubattery, it says dropping to 95% reduces cycle cost from 1.0 to 0.62.
Put differently, a 5% reduction in capacity is a 38% reduction in wear and tear on the battery.
Sadly, Accubattery for Android isn't that useful. You can set a limit like 95%, but it doesn't stop charging. All it does is trigger an alarm/notification when it reaches 95%, for you to unplug the phone. Of course, this happens in the middle of the night so it wakes you up just to unplug your phone. NO thanks.
Android needs to make it possible for apps to turn off charging while plugged in (so Accubattery can work properly without waking you in the middle of the night), or incorporate this feature into the operating system.

I am currently at 81% capacity on my iPhone 11. I do use it a lot and I have tracking features turned on for health and fitness.
 
Lots of posts about making your "battery last longer" when on an iPhone Apple Store only charges a mere $49-$69 to get a battery replacement. My iPhone 11 sits at 84% capacity over 3 years and the plan is by end of year hand to daughter or trade in for iPhone 14.

I will only state I don't think about battery charge except when low then put onto my MacBook Pro 90W Usb-c charger I found and it gets to 50%in 30mins. It seems to slow down after that. Th

Neat idea on carbon footprint to pilot feature for likely future of peak energy rates.
