However, late last year Apple did reveal that a small number of iPhone 6S devices manufactured between September and October 2015 had a battery issue and were eligible for free battery replacement. Then in December, and only on the Chinese version of its support site, Apple announced that there were some phones “outside the affected range” of phones that they knew had a battery defect that were also shutting down. This prompted the company to integrate new battery diagnostic software in an iOS update for all users. That software is out in the field now, gathering data for Apple. Early this year, a report surfaced claiming that Apple might extend the battery-replacement program to iPhone 6 devices… More at Mashable.
Some good information here. My daughter’s iPhone 5s does exactly this so I will give Apple a try to see what they say. Can’t be a worse experience than the bendy iPhone 6 one I had recently.

My main battery weirdness (with a 6, going from medium-charge to shutting down, followed by a charge bringing it back to middle values very very quickly) happened in the cold – holding it outside.
Batteries are the thing most in need of a breakthrough, but that kind of chemistry and engineering is tricky! Too bad some other alternate forms (mechanical / gyroscopic / kinetic storage, compressed air, radioactive…) are not feasible for various reasons… but fun to think about.
