The gas gauge on my Audi does the same thing. The whole point is that the gauge shows an approximate quantity of power and is not accurate. Ignore it if it bothers you.

I thought you were forcing yourself to not be OCD about the battery anymore.

I am. That's why I'm noticing this now that I am charging to 100%. I'm done trying to keep it from 40-80%. Just seemed weird to me how long it stays at 100% is all. Ever since I've started charging overnight I have yet to end a day with under 65%(except the weekend I didn't charge and got it down to 10%). I'm not worried, just curious about how apple programmed this battery is all. None of my Android phones have ever done this, so it's new to me.
 
Best thing I did for my iPhone happiness was to turn off the % reader and plug it in whenever I wanted. I've been doing this since my 6+, 6s+, and now 8+. I kept meticulous logs on the design capacity and charge cycles doing this and after nearly 2 years of ownership and 240 cycles, the phone's design capacity barely suffered at all. Since I work at a desk, I leave the phone plugged in or on a wireless charger most of the day/night.

I've had Android phones mimic the 95-100% thing - laptops do this too. Show 100% while for the health of the battery, cycling between 95% and 100% while plugged in as to not bother the user.


I too tried the 40-80% but found that my chargers (which can supply 2.4a+) made the phone get warmer than the trickle charging from 85%-100% and figured it probably evened out somewhere so I just plug it in whenever I can and rarely see below 90%. I think the whole 40-80% is better for electric cars that get used a bit more and have more load/heat/etc...

My wife's iPhone - she lets it drain to 0 frequently and doesn't give a second thought about battery - her battery design capacity hardly differs from mine. So I try not to worry bout it much.
 
My Macbook Air does the same thing.

Another one related to the battery % is it can be down to 5-10% but 10 minutes after plugging it in to charge, it's up to 45%. Try explaining that to an 8-year old with her iPod touch !

I personally don't think it is deliberately programmed somehow to show 100% for an extended period to deceive users
The iPhone will stay at 100% for several hours even though if you plug in the phone and open coconut battery, the actual % may be about 96% after a few hours. The iPhone rounds up or down and this is why the % will say 100 for a really long time. iPads are the same way.

MacBooks did the same thing.

So is that why on coconut battery it reads my battery percent always about 2-3 percent lower than what it says on the iPhone?
 
All I can tell you is the battery on my X has been garbage for the past month. Yesterday I took it off the charger, didn't touch my phone for ~4 or 5 hours, when I picked it up it was at 30%. The battery is depleting so quickly and I don't know why. I've done all the recommendations like turning off background app refresh and all of that. None of the usages in the battery usage list are out of the ordinary.
 
Measuring battery capacity accurately is difficult. The level of power remaining over time isn’t a perfectly straight line and it doesn’t stay the same throughout the life of the battery. I just turned the percentage indicator off and I charge my phone when I can.

I’ve had the percentage off for the past year. Such a relief. I have a 8 plus so I don’t really worry about the battery and I get the percentage after 20% anyway.
 
Never worried too much about it. I know that standby battery life is really good, so if I remove my phone from charging and just leave it, it can stay at 100% for a long time. The phone lasts all day for my needs, that’s my main concern for now. I have the 8+. My iPad, AW3, and MacBook Pro all behave similarly.
