A:AnswerMy husband and I both have iPhones and we both could charge our phones multiple times a day, for like 2-3 days without having to recharge the charger itself. I would say it take a good 6-8 hours to get a good charge/ fully charged! Also it didn’t seem to take too long for my phone to charge all the way up, but I also never let it get past 30%. Hope this helps.
A:AnswerIt seems to. Any battery, if left on the shelf for a long time, will run down. I haven’t seen any loss of capacity in the short time I’ve had it.
A:AnswerIf your iPhone uses a USB-C power adapter, then yes this portable charger will be compatible with your phone since it has outputs for USB-A and USB-C.
