Will Couple Battery fully charge my device?

The Couple Battery family are designed to offer you a convenient, on-the-go, boost of power to keep you going until your next charge.  We have balanced battery capacity with slimness to ensure you get just the right amount of power when you need it, for larger devices this will mean a top-up rather than a full-charge. 

All of our Couple batteries have a 3,000mAh capacity; how much it can charge your device will depend upon the size of your device's internal battery, and the level of use during charging.  As a guide, the capacities of supported iPhone models are as follows:

Phone Model	Battery Capacity
iPhone X	2,716 mAh
iPhone XS	2,658 mAh
iPhone XS Max	3,174 mAh
iPhone XR	2,942 mAh
iPhone 11	3,110 mAh
iPhone 11 Pro	3,046 mAh
iPhone 11 Pro Max	3969 mAh

The quickest and most efficient way to charge your device is with it powered off or on flight-mode.  Using your device will consume an amount of power as you charge, which will mean your Couple battery does not not fully charge your device, even if the available capacity allows it to do so.
