From a full overnight charge and normal light use, my iPhone will show 10% or so battery left in a few hours and go into low power mode.

I plug in the charger and the 10% goes for 50-70% almost instantly and the phone contours to operate normally.

See the photos.

Any thoughts?

I have had something similar in the past. I tried a while and reload and fixed it. I think it might of been a software bug that was incorrectly reading the battery and calculating the percentage.

If you were selling a phone with these symptoms and wanted to be upfront about them and offer a reasonable discount, what would it be?

For example, say an iPhone 6 64GB in good condition without battery issues has a fair market value of $240.

A new battery from Apple is what $89 or something around there ? I'd just be like battery needs replaced and lower it at least by some of the cost of the battery.

Apple can also conduct a free battery test of your iPhones battery health in store or over the Phone. The threshold is 80% I believe and Is the recommendation for a replacement. A replacement battery is $79.00 without coverage.

Thanks. I priced it at $160 down from $240. (I use Movaluate for FMVs) It looks like you can do the repair yourself for much cheaper than the apple rate too.

I think this is defect in iPhone 6's or iOS 10 that Apple won't cop to. I had a very similar issue with my iPhone 6 that was performing flawlessly until iOS 10. Then the battery got flakey. I tried everything I could -- soft resets, hard reset, restore, etc., etc. Took it into Apple and they hooked it up to their diagnostics and said my battery was at 90% -- healthy.

Finally I couldn't take it anymore and bent over and bought an iPhone 7 even though I was holding out for the "all new" 2018 model. Will still buy the 2018 model, but annoying I had to replace my phone because Apple won't admit there is a bug in iOS 10 or a defect in the iPhone 6s battery that reposts a false positive.

This happens to me too, but only after I charge the phone to 100%, I just charge it to 8X% and then the battery frains like normal.

Well I changed the battery myself, not too difficult using Ifixit tutorial.

After a couple of cycles the phone is behaving wonderfully. At the end of a typical day I still have 40% left whereas before I'd have had to charge it at least once during the day.

Well pleased

Now when's the 8 coming out

That's really good. Is this the first time you replaced the battery of your iPhone 6? How long have you been using the phone for?

Well I bought it when it first came out - however long ago that was.

First battery change.
