... paulcb can you explain this sentence "normal mobile use will usually result in the one charge cycle/month..".
Normal mobile use would be, for example, using 50% and then charging it, using 10% and then charging it, using 75% and charging it, and so on.
Two 50% discharges/recharges equals a single charge cycle and four 25% discharges/recharges equals a single charge cycle, assuming they are fully charged each time.
Note that you don't have to fully charge to 100% everytime you charge it. Essentially, just use the device as a mobile device (using the battery) and charge it when you get a chance.
