    Anybody heard if the replacement batteries Apple is installing through the iPhone 6s battery replacement program has a higher capacity than the original battery? I know it seems unlikely but different battery apps (I know these can't by 100% trusted) have reported my battery capacity as 1800 mAh since I had it replaced whereas the original battery was reported as 1715 mAh (which is the official capacity of the 6s battery). Either way my battery life has been fantastic since I've had the battery replaced.

    As you said, those apps are not reliable. At least those from the App Store. So enjoy your new battery, if Apple replaced yours, believe me, something wrong was on your original battery. Apple doesn't make this replacements without a real reason (and not always do it).

    It is very normal for a battery to have a higher current capacity than design capacity. If you have a Mac, Coconut Battery is these most accurate way to verify your capacity on your device. Coconut Battery can be 100% trusted as it reads the hardware directly. Pre-iOS 10 those apps for iOS were also very accurate, but iOS 10 changed that and now the ones you find in the app store are just estimates, but Coconut remains spot on.

    But back to the issue at hand. Because batteries are not a "100%" science, sometimes capacity is more or less than design when the battery is new. It means you won the battery lottery if you have a higher starting capacity, and means it will probably live longer than the 500 cycles that it is rated.

    For example, my 7Plus start with 2990/2900. Today, I am at 114 cycles and still at 2950/2900. So I am still at almost 102% design capacity, even though I have consumed 114/500 cycles. My iPad Air 2 on the other hand wasn't as lucky. It started at 99.8% capacity and now with 100 cycles (of 1000) it is down to 97.4%. So that device probably won't reach the 1000 before the battery is consumed, but its entirely normal.

    I think you are just enjoying a decent battery compared to your bad one. The battery apps can be all over the place.

    You're right, coconut battery shows that my new battery (which now has a total of 11 charge cycles on it) isn't holding anywhere near 1800 mAh. Oh well, I guess I am just enjoying having a phone that doesn't die at 30% or if I use it outside and there is a gentle breeze... I feel like those of us who qualified for the 6s battery replacement program lucked out as it seems many who don't qualify are having similar problems.
