iPhone Battery Replacement

[alvesik]

My 6s battery has gotten pretty lackluster, and after severe battery issues with previous iPhones, I keep a close eye. This past week I have had insane fluctuations in capacity from as low as 65% of original to its usual spot of about 89%. This problem seems to only be getting more extreme and today it has pretty much stayed in the mid 70s but actually just crept back up to 89%.
I know it needs to be below 80% for a warranty claim. My question is if I took it to Apple, what is their procedure for determining battery capacity?
My concern is when they check it, it will be in one of its increasingly rare above 80 capacities. I go out of warranty September 25th and I would really like a battery replacement because these radical fluctuations are new and I do not see them getting any better.
P.S. I am only at 393 cycles.

While it is true that battery replacements at Apple are covered under their limited warranty only if it retains less than 80% of its original capacity, I believe that threshold is an approximation. I recommend you go to Apple and explain your problem. Since most battery problems are rarely demonstrate-able, they have a diagnosis tool which determines the iPhone's battery condition. If your battery is indeed defective, more likely than not, it'd have started showing signs already. If they are convinced, they will certainly replace your battery. Additionally, whenever you observe a fluctuation take a screenshot (i.e. before and after). The timestamp from that may be helpful when explaining your issue to the Apple Genius.

Please note that battery retaining less than 80% of its original capacity pertains to the battery's capability to hold the charge. It has nothing to do with the battery percentage shown on your iPhone screen. For instance, your battery may retain merely 60% of its original capacity and yet show 100% when fully charged.

I know that and all of my percentages were referring to its percentage of original capacity. Sorry if I wasn't specific enough! My battery is constantly fluctuating now between anywhere from 65-89% of original capacity and this only started on Saturday. The only other time I have had this happen is on my 5, where the battery soon totally failed and I later got reimbursed through the recall program. Right now I'm on 33% and it says it will hold 78% of original but just 10 minutes ago it was 87% of original.

If it's not below 80 of original at the time of checking, do I stand any chance?

Sure you hold a chance. All the evidence points at a defective battery. Go visit an Apple Store. Do let us know how it turns out.
