Lets start out by saying that modern lithium batteries have a built in micro controller that controls how the cells charge and monitors their discharge as well. The micro controller reports the health or capacity of the battery to the phone. Which in tern shows us the percentage of battery left based on the current charge level compared to maximum.

Well as lithium batteries get older like all rechargeables this maximum becomes lower. However the controller does not compensate for the difference and reports the original maximum to the phone. This is why we sometimes see 90% when we take it right off the charger.

Now the recalibration runs the cells till the controller goes into emergency shut off to protect the cell voltage from dropping to low. This takes the power off the controller and resets it. When you power it back up by charging it the controller will now "relearn" the battery. This is why it is important in this process not to remove the phone from the charger until it is completely full.

The controller has now learned the new maximum charge level for the phone and now reports it correctly.

That was wonderful. If i could thank you multiple times for that explaination, i would.
