Also this is the very first time i've seen a "Beta Feature" on a FINAL ios release.

I've never seen a weather beta, or Safari beta or mail beta, pretty dissappointing...
Voicemail transcription was beta at introduction, as well as portrait mode.

What's happening is that the battery that was installed in the phone at the factory had a higher real capacity than the specification. For the iPhone 6, the battery specification is 1810 mAh, but the battery you got (lucky you) probably had a higher real capacity than the specification - essentially giving you a bigger battery.

The new iOS 11.3 battery power management feature is comparing YOUR battery to the specification. Your battery may have degraded 5% from when it was new, but if it actually had 5% more capacity than spec when new, the power management software wouldn't know it... So it would appear to be at 100%.

If Apple wanted to be sneaky, they could under rate the battery specification and all new batteries would exceed it. Then we would all have batteries lingering around 100% design-capacity for years... though they still would have degraded.

Is it possible for sane size battery to have more mAh than others? That’s interesting.
Do you think the new batches of batteries prepared for $29 replacements due to the lawsuit have slightly bigger capacity too? I just got the replacement done a few days ago so I’m hoping that’s the case:)

I don’t see how this can be accurate. Anyone think it’s simply wrong?
How many hours does your iPhone battery last everyday with your average usage?
 
A couple of factors:
1-It's probably in really good health, 90's or mid to high 80's in percentage of original capacity. But it's not a 100%, degradation is law.
2-I bet you never dropped your phone on a hard surface. High G impacts can sometimes impact the battery life and stability.

I’ve dropped it three times on a hard surface. The first two times were tile or wood floors. The third time was on a rock, which shattered the screen. That was in the summer of 2015. Had the screen replaced.

I’ll have to check the average usage and post back.
 
Have you ever done a factory reset on it? I know I had a battery issue with my iPhone 6 right before it was out of AppleCare+ warranty when I had gotten my iPhone 7 Plus. I had tried resetting the phone to see if the issue persisted. When I brought it to Apple to diagnose, they had said also that the phone had 100% capacity which they said should be impossible because of the age of the phone and did the replace because of that. I think the battery stat that the phone and Coconut Battery read can be skewed by a factory reset since diagnostic data is erased.

I’m not even sure how to do a factory reset. I’ve done hard restarts but that’s pretty much it. Unless the Apple store did something to it when they replaced the broken screen. But that was nearly three years ago.
