Dell XPS 13 2015 Broadwell Infinity Display Owners Thread

For those concerned with the battery overcharging when constantly plugged in. Set my to "primarily AC use" in the Bios.
In windows it was saying that my battery was at 100%. But when you check the battery in the bios, it actually says its sitting idle at 96%. Which means that primarily ac reports 100% in windows, yet actually limits the battery to 96% preventing overcharging.

 

you can do the same with the dell command power manager.
the limit to stop charging at 96% is not for preventing overcharging (which cant happen) but because it would reduce the battery's lifespan if constantely being topped off to 100%.
it would even better to stop charging at 80 or 85% and start charging at around 60% as li-ion or li-po batteries like the most being held in those limits.

that would be the best configuration if you stay plugged in most of the time. if youre going to need a full charge, just set the power manager to standard and it will charge your battery to 100%.

 

Can the Dell Power Command Manager do that?

 

yes.
you can set it manually in the bios aswell but the power manager is much more comfortable because you can change the setting on the fly

 

Where is the Power Manager? I think I uninstalled it, any idea how I can recover?

 

dell support website - drivers and downloads

 

Got it, so that would be Peak Shift 80%? Any other recommended settings?

I was never satisfied with tbe Bios setting because although set to 80% it would stop arbitrarily from 50 to 80

 

It would only do that if you set start to 50 -- it wouldn't begin charging until the battery dropped below 50%. To avoid that, just set both start and stop to 80. (Well, ideally to 75 and 80 or thereabouts, so it isn't constantly topping up to 80)

 

Thanks, but I disabled that because I installed Dell Command Power, peak shift to 80%, but...it charged to 100%...

 

That would mean installing Dell command power. Its build right into the BIOS. My system here in europe didnt come with dell command power manager.

Im still confused as to how dell command power manager relates to windows power plans. If its replaces or even overrides them.
