I just got this battery, and although the form factor is a bit large for the 3000mAh capacity, it's light and the built-in micro-USB and Lightning cables are great. I tried it out on a completely drained iPhone 6 (1,810mAh battery), and it charged it to 100% in about 2.75 hours. That's the good news.
The battery was more or less close to fully drained after this exercise. Although I know that there's a loss in efficiency when using one battery to charge another, and charging the last 10% of the iPhone's battery takes more than the first 10%, is a loss of 33% of capacity of the MyCharge battery to the charging process to be expected? (Over time, it's going to get worse, of course, as the MyCharge losses capacity.)
Thanks in advance.
