Hi all,

is there any way for me to set my iPhone X to notify me when it reaches 80% charge whilst charging?

wish to do this because I try to maintain my iPhone X battery between 70% and 80% as this is the healthiest lifestyle for the battery.

thank you!
 
If you charge in Low Power Mode, you get a notification once the phone reaches 80%. It doesn't make any sounds or cause any vibration though, so you need to be on the lookout for it, at which point you might as well as eye the battery meter yourself.
 
Actually the healthiest for the battery is to keep it over 30% and under 80-90%. So use it as you do but if you charge during the day don’t let it go completely flat or completely full.
 
No harm in asking, but the barely perceivable gains you’ll experience in battery longevity are not worth the impracticality of trying to hover your charge in a certain range.

Just use your phone and don’t worry about it.

Hey, don't be sorry. It is never wrong to ask and gather information about topics you find interesting! I'm a huge battery nut and I know more about batteries than a lot of people I know because years ago, I asked this same question and spent a lot of time reading about it.

SoC = Depth of Discharge

Keep in mind for the first 1000 cycles, not a ton of difference.

I highly recommend Isidor's book: http://batteryuniversity.com/buy/

Most of my usage is 90%-100% and I find that even after 240 cycles, I'm within 3% of capacity of when I started even after 1.7 years. This has worked for me for the last 7 years -- but I'm not religious about it - I'll drop lower if I need to but I usually bring an Anker battery brick with me if I know I'm going to go out for a long period of time. Dropping phone to 0% is worse for it than doing 100%.

Don't leave your phone in the hot sun for hours and hours.

Most people won't see more than 500 cycles in 2 years - My wife gets about 360+ and I get about 240+ in 2 years. So you'll be fine. But read up and do whatever you want, it's your phone. Being obsessed about the battery can be fun as long as it doesn't prevent you from enjoying the phone. 🙂

If you have a Mac get coconutBattery: http://www.coconut-flavour.com/coconutbattery/ - gives you more stats on your phone.

My phone spends most of its time on a charger during the day and night. Done this since my 6+ many many years ago - and it hasn't hurt the battery life at all.

Thank you very much for your detailed reply! Some interesting physics there...

you can use low battery app which has charge / discharge notification with customizable percentages. Can't find it back on the app store though...

however, this is too much hassle to preserve a sub-10$ battery cell...

For expensive batteries, eg. electric vehicles, even a macbook...yes keeping it in the 20-80% zone is a must to preserve the investment, an iphone... nah, ill rinse it down and change it every 2 years.

Does it say it in Apples support pages? No. So just charge it to 100% and use it.

The best thing for you battery is to charge it often. Not to keep it between 70%-89%

Unless that leads to overcharging.

The best thing to do is never let it drop below 20%, never let it get too hot or too cold, and never always keep it plugged in at 100%. Batteries want to be used. Thus the 20-80% range is the best operating zone. Nothing wrong with charging it to 100%, but constantly keeping it between 80-100% is bad.

The only thing I do that's OCD RE batteries in phones- leave them charged around 50 while powered off and keeping stored for a prolonged period. All of my old devices still hold charges fine because of this.

I'd rather save myself the brain damage and just get a new battery in 2 years if my MacBook Pro needs one. Thats just me though.

I know I've taken a hit on this.

Difficult not to do when you live in Phoenix in the summer, driving around in a car with broken A/C and windows that won't roll down. Not often in direct sunlight but with ambient temps inside the car around the same as the outside it becomes a rolling sauna. Which I know isn't good for the phone.
