My newish Lenovo laptop had the decency to pop up a message recently to remind me that running the laptop most of the time off the mains adapter (i.e keeping it at full charge) wasn't good for the battery and would shorten its life. However, bearing in mind that battery life is also dependent on the number of charge/discharge cycles, it is clear that running mainly from battery is also not good for battery life. From what I recall, lithium batteries are best kept at around 70%(?) of full charge. So, what is the Forum's view on the best way to maximise battery life?
