my iPhone 6 Plus shut off at 25 percent tonight. It showed the battery and red symbol. I was taking photos of a parade and it just shut off. I plugged the phone back in via my car charger and immediately it showed 25 percent left now.

There has been an issue with batteries intermittently shutting off with iPhone 6s units similar to your story - but those are with the "s" models.

If you haven't done so before, run down your battery until it goes to 0% then do a full uninterrupted recharge to 100% overnight to recalibrate the percentage counter.

Apple provides free battery change for those with iPhone 6s, but those with 6/6 plus have no such treat!

Thats because the iPhone 6 is 2 years old and do not have defective batteries that degrade prematurely. If an iPhone 6 shuts down with power then one of two things are occurring. It has either a worn battery because its 2 years old, or there is a bug in iOS that prevents the percent from being read properly.

There is the possibility that at least some iPhone 6 phones have batteries that aren't as good as they should be and degrade faster/earlier than typical ones should and do in other phones. No way to rally know that unless something comes out to support something to that effect, but the possibility for something like that is there.

Yes. It's possible that there are defective batteries out there. 100% possible. But it's not a wide scale issue. Otherwise Apple would probably issue a recall. The majority of the iPhone 6/+ that are shutting down premarteuly are most likely caused by depleted batteries. Not hard to go through 500 cycles in 2 years.

Right, the scale is probably one factor in all of it. Another would be the attention it is or would be getting to actually look into and perhaps admit to the issue (if there is one), which kind of goes back to the potential scale influencing all of that in one direction or another. And certainly the older the device and battery is the easier to is to attribute just regular wear and tear to its potential issues, even if there might be something more to it causing earlier/faster degradation than expected.
