Samsung Series 7 Ultra Notebook - battery care - should I be cycling the battery charge?

Hi

I own a Samsung Series 7 Ultra Notebook 128GB SSD 13.3" (which I upgraded to 512GB SSD)
Model: NP740U3E-S04UK
URL: NP740U3E - OVERVIEW | SUPPORT | SAMSUNG UK
It is powered by a Li-ion 4Cell (57Wh).

My question is it okay to leave it plugged into the mains and being charged at 100%. Or would it be better for the battery (cell) to be cycled from say 80% to 90% charge?
If the latter, what is the best way to set this up and what are the best exact percentages to use to cycle between?

If you have the Battery Life Extender (BLE) in Settings (press Fn + F1 then look under power management) then enable it. It limits the maximum charge to 80%. Then only disable BLE if you need to fill the battery in anticipation of maximum time away from the socket.

If your battery is at 100% and you enable BLE then the battery won't get a top-up charge until the charge drops below 80%, which will be several weeks if you are connected to the mains.

If you don't have BLE (Samsung, for reasons best known to themselves, dropped it on the new models) then just leave the computer plugged in. It won't get a top-up charge either until the charge level drops a few percent or you unplug / reconnect the mains power.

There is no point in unnecessarily discharging / recharging the battery. If you look at the battery properties in HWiNFO you can see the wear and, probably, the charge cycle count. My current NP900X4C is at 0% wear and 4 cycles after 3 months. It is predominantly plugged into the mains and I have BLE enabled except for topping up the battery to about 95% before going on a journey.

BLE - yes installed already. Exactly what I was looking for. Thanks. (I wonder why Samsung have stopped installing it)

HWiNFO - what is that & where do I find it?

Many thanx

 

HWiNFO is a great (and free) system monitoring tool. You'll see many references to it around here. Just Google it, you can't miss it.

Regarding BLE, it's actually a firmware feature (enabled/disabled either in BIOS or in Settings). And as John said, Samsung dropped it in recent models, claiming that their batteries are now intelligent enough that it isn't needed

 

HWiNFO was overkill for me - too much detailed stuff that I didn't really understand. But I found it EXTREMELY hard to download as the interface was so confusing (with deliberately excessively disingenuous adverts everywhere) and also it suggested I install a driver update utility which like a fool I did but when I ran it, it suddenly started demanding money. So as a matter of principle I have uninstalled it.

On the upside it did give me a chance to correct the fact the my restore points were not being created correctly.

 

Did you go to the right place? I see no adverts (but maybe my AdBlock Plus is working effectively).

Use the portable version listed here. Just unzip the files and run it.
