Hello:) First of all let me say I find it such a compliment coming from you. I also find just following your posts have added so much to my growing knowledge as well…so thank you very much. I do tend to agree with you on point 13 but so much other good info I thought to post it anyway. Again thank you.
Batteries are consumables; they lose a little capacity every time they are discharged, then recharged. On average this works out to about a 1% loss for every 25 “full charge cycles” ( some will be a little more, others a little less). As one example, if you charge the phone overnight, every night (and that is what you should do; it is a best practice), it starts the day at 100%. If it drops to 20% by the end of the day before you charge it again overnight that counts as 0.8 full charge cycles (20% to 100%), or about 24 full charge cycles per month of use. For this example your battery capacity will lose about 1% per month. Of course, if the end-of-day level is higher than 20% the capacity loss will be a little less, and if it is lower than 20%, or you charge it during the day, the capacity loss will be higher.
The absolute best way to improve the life of your battery long term is to enable Optimized Battery Charging (Settings/Battery/Battery Health) and charge the device overnight, every night. The battery will fast charge to 80%, then pause. During the nighttime pause the phone will use mains power instead of battery power, allowing the battery to “rest”, and thus reducing the need to charge the battery quite as often. The phone will resume charging to reach 100% when you are ready to use your phone; it will “learn” your usage pattern.

Hello:) In addition to the excellent post by Lawrence Finch …I found the article above to be helpful as well. Having good info and putting it into your daily charging routine is perhaps the very best way to care for your iPhone battery.
That’s a really good article; thanks for linking to it.
I have only one objection to it: point 13. It is not necessary to recalibrate the battery gauge on any newer model iPhone. It was necessary on older phones, because the battery gauge measured the battery consumption continuously vs the battery voltage and extrapolated the life of the battery given the current state of charge. However, the models released in the past several years have a built in monitor that does the calculation for state of charge. That’s why if you replace a battery with a non-Apple battery you see a notice that it can’t report battery maximum capacity.
And the symptom it mentions, of the state of charge bouncing around, means that the battery is failing due to high internal resistance (which is a different failure mode than just loss of maximum capacity).
But everything else is right on, and good advice. And following point 13. won’t do any harm, it just isn’t necessary.
All of the articles posted should help. Please know that battery are consumable and do degrade over time.
