My answer to How many times can a 10000mAh rated power bank charge an iPhone 6/6S?

Answer by Allen He:

How many times can a 10000mAh power bank fully charge your iPhone 6/6s? Actually, this is a difficult question to answer.

The number of times a 10000mAh power bank can fully charge your device is relevant to 3 primary factors.

1.— What device you are charging with a 10000mAh power bank —

Generally speaking, a good rule of thumb is to divide the mAh of 10000mAh power bank by the mAh of your device battery.

So a 10000mAh power bank can “theoretically” charge an iPhone 4s plus from 1-100% 4.1 times (10000 / 1810 = 5.5). –iphone6/6s battery capacity is 1810 mAh.

Keep in mind: this is never 100% accurate as there still some other factors involved which will influence the charging times, which is always higher than what a 6000mAh power bank can practically give. Keep reading…

2.— What is the device doing while it is being charged —

It’s not strange to see the device charged, for example, by a 10000mAh power bank, while you’re still using the device. So is there any difference between using the device while it’s plugged into and leaving the device alone or on airplan mode while it’s charged? The answer is undoubtedly YES.

If you are watching a movie on your device while the 10000mAh power bank is charging it, more power drained from the 10000mAh power bank and meantime it seems that your device is never charged. That is because you’re taking the power more quickly than the 10000mAh charges your device.

If you leave your device alone or on airplane mode while charging, you will get more fully charges since the device is not taking much battery charge at all while the 10000mAh power bank is charging up the device.

3.— The charging cycles of the power bank 10000mAh —

More charging cycles the power bank gives, its capacity will reduce. Theoretically, the capacity will reduce to 80% after 300 charging cycles. If so, a 10000mAh power bank may have a 10000mAh capacity. This is also relevant to the temperature when you’re using your power bank. And this point I believe you could find out on the manual when you brought the power bank.
