In the past we have some old advice but with the new batteries the rule changes to its short form of ABC or Always Be Charging. This is not an offer to duplicate the web content on this but how just leaving a current design phone plugged in gets you the most months of battery life.
Also, any good tech can change batteries. When they mean you can't change the battery they mean consumers.

I am considering to buy this cell phone, but I see from the specification that it is not possible to change the battery.
Normally this type of battery will last for 2 years, when the performance will start to reduce.
Does anyone know how to solve this problem?
