I wanted to start this thread because of the lack of knowledge people have about a lithium ion battery compared to the older ni-cad battery.
First The is lithium ion batteries DO NOT develop a memory so people thinking you should drain your battery till it is almost dead and then charge it because of the "memory" of the battery are wrong.
Second The charge cycle for a iPhone battery is from dead to fully charged. So charging your battery often means many less full cycles. A lithium-ion battery provides 300-500 discharge/charge cycles. The battery prefers a partial rather than a full discharge. Frequent full discharges should be avoided when possible. Instead, charge the battery more often. There is no concern of memory when applying unscheduled charges.
A lithium-ion battery in use typically lasts between 2-3 years. The worst condition is keeping a fully charged battery at elevated temperatures, which is more a problem with running laptop batteries. If used on main power, the battery inside a laptop will only last for 12-18 months.
So again:
Avoid frequent full discharges because this puts additional strain on the battery. Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Recharging a partially charged lithium-ion does not cause harm because there is no memory. (In this respect, lithium-ion differs from nickel-based batteries.)
Keep the lithium-ion battery cool. Avoid a hot car. For prolonged storage, keep the battery at a 40% charge level.
I Hope this sheds some light on the subject. If you do not believe me please feel free to research it yourself.
in the sense that you shouldnt charge them to full capacity?? or you shouldnt leave them on full charge for extended periods of time?
Ok so I have a car charger for my iphone. Does this mean that it is actually a smart idea, to pop it in the charger whenever i get into the car?
Sorry guys, its important.
Here is what I want to know: is it better to charge your battery to 100% (regardless of where the charge was at - 10%, 50%, 80%), or is it ok to charge it to whatever level you want, and will that type of behavior have any long term effects on the health of the battery?
To be more specific: does it hurt the battery if you plug your phone in for 5 minutes, just to give it say 10% more juice? I ask this because whenever I charge my devices I never unplug it from a charge until it's 100% charged, but my friend has no problem plugging in his devices for 5 minutes, 10 minutes, whatever it takes to get a bit more charge so he can use them right away.
Overall, when he DOES charge his battery to 100%, he almost always has a dead battery long before I do. This happens on all of his devices, including his iPod, camera, and his iPhone, whereas my battery in those devices always lasts much longer. Thoughts?
