Battery optimization option by daily usage

Unfortunately, the inclusion of all the choices about optimization and data on battery health and charge cycles has caused many people to seriously overthink the whole thing.

Choose "Optimized," continue charging overnight, and don't worry about it. Your battery will be fine. Even without Optimization, the battery will stop charging once it reaches 100%.

Charging overnight, if iCloud back up enabled and you also have the phone connected to WiFi means it will automatically backup every night. So, yes, keep doing that.

Optimized Battery Charging may or may not engage, but frankly I don't pay any attention to this.

Exactly!

I'm confused.

Apple in its web documentation states Optimized Battery Charging is designed to reduce the time the battery will spend fully charged, example overnight, because prolonged high state of charge will reduce battery lifespan. This is why it charges until 80% then stops and only last hour charge to 100%.

What you tell is the total opposite, sorry.

In theory, everything Apple is saying is correct. In actual practice, I don't think it makes that much difference. So, you fret and worry about your battery and you get an extra month of usable life? Or, you can simply use your phone, not worry about it and, in a few years, either replace the battery or, if you're ready, replace the phone. Based on your usage and barring physical damage, your battery is going to last you a very long time. Just don't leave your phone in a hot car in the sun during the upcoming summer months. That can destroy both your battery and your screen if you leave it too long (I mean hours, not minutes).

Apple implemented a number of features after their failure to properly communicate why they were throttling performance on phones with dying batteries (hint: it wasn't to make people buy new phones). The battery health indicator encouraged people to try to micromanage their battery life. Optimized battery charging, in my opinion, was a response to that, an attempt to get people to stop worrying so much.

Even in the days before battery optimization was a feature, I charged my phones overnight, every night. I use my phone a lot and I generally get about three years out of a battery.

Personally I can't understand what could be better behaviour to preserve battery health & lifespan according to my very light daily use.

Charge your battery overnight so that your phone backs up every night. And don't worry about it. With your usage, your battery is going to last a long time.

With Optimized Battery Charging turned on, I don't know if it is better charge daily to 100% from 90-85% or let discharge the battery 2-3 days since about 30-20% and then charge overnight to 100%.

No strong studies there are around, neither from Apple itself, only controversial point of views.

You're overthinking this. None of this matters that much.

Thanks for the answer.

The point is, my tipical daily battery usage is about 10-15%, so quite never under 80%.

So, "Optimized Battery Charging" can't engage because when I plug in the charge is over 80% or it will engage however?

I don't believe it will engage. Don't worry about it. Having it turned on will hurt nothing.
