iPhone 6 - new battery health

Hi guys!
Since the old battery in my iPhone 6 got too sensible to cold climates (it would go from 50% to dead within minutes if exposed to temps below 60 F), I replaced it myself with an original Apple one.
Everything was perfect, Coconut battery gave me stable 98-99% battery health.

Then I had to use a navigation app and connected the phone to the car charger (which, by the way, was not even able to charge the battery: using the navigation app, the battery just didn't discharge).
Since that moment, my battery health fell to 75-80% (I had around 10 charge cycles on it back then).
I now have about 45 cycles, tried every trick in the book, but it just stays there.
Did I really ruin a new battery using a car charger?

No L-Ion battery will work long when exposed to -60F.

Where did you get the original Apple battery to use as a replacement? No one has these except Apple and if purchased any where else, could be a knock off.
 
Battery health will fluctuate 1000x times in a day. Depending on the condition of the battery is in when you take the reading. With that being said, after 45 cycles, it seems that your battery has failed. Most likely is a defective one and it was not caused by the car charger; it was going to fail anyway.
 
It's 60 F, not -60 F... I think a battery should be able to work flawlessly at that kind of temperatures.
I got the replacement on ebay from Canada, it looks exactly like the old one, just a different product code.
It had 0 cycles on it. It is charging right now, Coconut Battery says 87% battery health.
Battery life on the phone is very good since I went to iOS 9.3.5, can a failing/failed battery still perform well?

Sorry for the error but the battery will not work at "all" temps.

There are so many fake iPhone batteries out there that I would have zero confidence that you have a real Apple battery. Looks can be deceiving. Want it done right, you need to take it to the Apple store.

How do you KNOW it is a real Apple battery? Just because they say so? LOL!

There are companies who make these all the time and they look almost exactly like the real thing but only Apple has the real thing unless it came out of a broken/used iPhone and then would not be used.

Case not closed

Gee Alex, you can copy almost anything. Have you never heard of counterfeit goods before.

Why would I ask the seller as if he is selling "knock off" batteries, he would not tell me so.

Do you think if it just looks like the real thing, it has to be real?
