I have been on 80% charge limit with my 16 Pro for the past year. My 16 Pro is still at 100% battery health. With the Air, I’m not sure the battery will last me all day at 80% charge limit.

For iPhone Air owners, are you keeping your charge limit at 100%?
 
Yeah, I’ve bumped mine to 95% to start and will move it down as I see how much I end the day with in a week.

But my 15 Pro Max would typically end the day around 60% so I’m not a real heavy phone user. That’s why I felt safe getting the Air.
 
Since the Air has a smaller battery, I am going to keep it at the default 100%, which I don't normally do. There really isn't any real need to worry about battery health. If it goes under 80% in a year, Apple will replace free of charge. If I still have the phone in 2+ years and need a battery, I will either replace the battery or buy the latest Apple offering. Life is too short to get tunnel vision about battery.

Same - all my battery stuff gets charged to 100% - iPhone, iPad, Macbook, EV car, etc...

Never believed in undercharging since the battery management systems are so advanced.

No longer the old NiCd or gel cell days....

Just charge it to 100%. Different phone I know, but my launch day iPhone 16 pro max was at 100% capacity when I traded it in Friday. I basically always charged that phone wirelessly, whenever it needed it, overnight, every single night, to 100%.

To prevent living with a degraded battery at 80%, I will limit the charge to live with a battery at 80%. 🤔
I don’t quite understand that logic either. Get full use of the battery while you can, and if it degrades a bit over time, so be it.

I am trading in a 2yo pro max with 91% battery health, and I am pretty bad about just throwing it on a charger whenever, leaving it plugged in way too long, etc. I feel like for my use, 9% over 2 years isn’t too bad. Even with that, I’m still functioning on more than 80%.
 
I have never understood limiting the battery charge. Considering it’s a feature, I’m sure it serves some sort of purpose, but I subscribe to theory of just not having whatever that long-term anxiety is and using the thing as intended.

Neither do I, never believed undercharging if you are keeping the phone for a year or 2.

EV forums have this 20%-80% charge mentality and I never undestood that thinking - most likely from the Chevy Volt / Bolt and Tesla EV fires from early on about a decade ago ??

My philosophy is simple - always charge to 100% = you never know if you need that for an emergency, grid down, or disaster....

Which is bonkers considering all EVs now have a 20% buffer at the top to account for battery degradation and passive cell balancing requires it to be charged to full to balance so if you don’t you actually get worse range.

Right ?

I know there's a top end and bottom limiting SOC buffer built in to all the EVs I have had.

No wonder the battery warranties on EVs are 8 years - they know that even charging to 100%, fast charge, etc won't harm the battery.

I never worry these days about 100% charging any device (except for the old NiCd, NiMH, and sealed lead acid batteries of the 1980s technology).

Today is my first full day with the Air, and I started with 100% and will see how it goes over the next few days. May stick with 100%, maybe drop it depending on what I’ve got planned that day.

According to analytics battery stats, I’ve started with over 3200mAh (can be inaccurate)
