Want the answers to questions about the iPhone? You'll find questions and answers here.
i really want all my devices working at full capacity especially the battery and i want more info on the care of it. like should i charge a device for a specific time the first time i get it, and if its ok to let a battery go to zero and if overcharging is bad. by the way i have an ipod nano 5g, ipod shuffle 4g an ipod touch 4g, an iphone 5s, a ps vita, a surface rt, and im planning to get a macbook pro. ive had some of these devices for a while and some are fairly new. i really want to make these devices last and i dont want to have to replace them for any reason.
please help and thanks.
It is not good for Lithium chemistry batteries to become fully discharged, however, iPads, iPhones and iPods will shut off before the battery is fully drained. That is, when the phone goes from 1% to 0% and shuts off there is still plenty of charge on the battery. However, you should not let it sit for a long time after it shuts off, as the phone still uses some power even in this state. So if the phone shuts off due to low power you should charge it within a day or two.
You also cannot overcharge an iDevice. The charger is actually in the device; it is not the adapter that you plug into the wall. That is just a 5 volt power source. And the charger in the device will stop charging when the device reaches full charge.
One advantage of Lithium batteries is that they have no "memory effect". That is, you don't have to fully drain them before charging, and you can connect them to a charger at whatever the current state of charge, and remove them from the charger if necessary before they reach full charge. None of these activities will shorten the life of the battery.
It is a good idea to run the battery all the way down, then charge to 100% every month or so. But this is to recalibrate the battery gauge, it is not to "condition" the battery.
Thank you so much that was very helpful and do you know how long after an iphone shuts off does it take till it reaches zero? Bc i want to know how long i have if my iphone runs out of battery to charge it. And do you know if all my other devices listed in the original question also have a lithium battery?
