    CoconutBattery says my iPhone 6's battery is still over its design capacity a year into owning the phone. I find this really hard to believe, as batteries wear out with time. Battery life has been good lately, so I'm wondering...

    Did Apple finally do something to curtail battery aging? Or...

    Is CoconutBattery full of ****?

    Hmm pretty sure the actually capacity is 1810mAh on the iPhone 6...

    Here's what mine shows from Battery Doc.

    Only posting this because your screenshot doesn't show your phone at 100%.

    Try checking again after a full charge.

    Well, it finished charging and is still under "Maximum charge", so I guess you're right.

    Still, the fact that it still charges above "design capacity" a year in is pretty impressive.

    I'm at 89.7% health. Sometimes drops down to 70%. You're lucky. Could you please tell me which charger you're using and which cable? Also, what are your charging habits? Do you tend to charge it from 0-100 or 20% charges throughout the day...

    Most days I charge overnight, using an iPad charger brick plugged in under the nightstand and a normal Apple lightning cable. Typically a charge lasts me the entire day and I usually have 40-50% left when I plug it in before bed unless I've used the phone unusually heavily, or when traveling.

    If I have more than about 60% left for some reason, I don't bother to charge overnight.

    I rarely let it get under 20%, though once in a while I'll let it run completely down to poweroff to calibrate the charge meter.

    You know what is also impressive most people don't even know about? The logic the little square iPhone charger has built in. It will charge your battery to 100%, stop charging and let it drain to 97%. Charge it again to 100% and keep repeating this cycle to protect the battery until you unplug it.

    are you sure? I was under the impression the iPhone's power supply does that, not the brick.

    Yes, the charging circuitry is in the phone. The "brick" is just a power adaptor. It changes 110AC into 5VDC.

    My iPad 2 was at 101% capacity after 4.5 years and 200 charge cycles. So it's possible, but not necessarily common.

    My iPhone 6 was at 98.9% capacity when I traded it in after 1 year, had over 350 charge cycles. I practice good battery health though. I try to never let it drop below 10% and never ever let it die from low battery. That eats away health.

    You are right. All the intelligence is in the phone (which makes sense).

    Afraid the "brick" is stupid and the "brains" is all in the device.

    The Apple power adapters also change both 110VAC 60Hz or 220VAC 50Hz into 5VDC. So works worldwide, just need prong adapters for selected country.
