    I have the Series 7 in 17 inch, Win7 Home Premium and have activated the battery life extender option in Easy Settings, but the default and only value is 80% as far as I can see. My company laptop, a 5 year old Thinkpad T61, has a similar feature and my battery still lasts a couple hours, but it was more configurable and I have the "stop charging" point set to 95% and I'd like to be able to do the same with my Sammy. Is there some hidden registry setting that can change the 80% value? Any other way to change the setting?

    There's no way to change that percentage that I know of. I think Easy Settings works directly with the BIOS. There's nothing as potentially powerful as Lenovo's Power Manager but I suspect Samsung are worried that having an on / off option will be sufficient to confuse many users.

    One sort of work-around to achieve 95% charge is to temporarily disable BLE, let the battery charge to ~95% then re-enable BLE.

    Most Lithium batteries are best stored at the 70-80% charge mark. The reason is that the last 10% or so of a charge is the hardest to get into the batteries. This is where the cells unballance themselves the easiest too in a pack. Cell unballancing is the fastest way to kill a serial pack especially where you are trying to force a charge to some cells while the unballanced cells try to catch up their charge voltage. At 95% charge for the pack you are usually forcing the charge into some or all of the cells.

    For best results let BLE just do its thing. While 95% is better than 100% Samsung is giving you the option between longest possible overall battery life or deepest possible charge/discharge.......................
