...is wayward! I recently bought the Surface Book, my very first laptop... I am impressed with the quality of it's construction, plus the futuristic look to it. However, I am a little concerned with battery charge remaining estimate it gives. It seems not accurate, to say the least. My usage is light, since I don't use programs, like video editing, gaming, etc. I wonder if there is a better way to monitor the battery?
It probably is dependent on the CPU+GPU load at that moment, eg. like in you second photo maybe there were >30% CPU usage and for the third photo, less than <5%...so it counted based on the load.
Every battery is different so it has to be estimated. Plus, batteries don't charge at a linear rate. The closer they get to a full charge, the slower the charge rate becomes. Plus as each battery ages (regardless the battery technology) it loses capability. There is no real way to measure that in a manner that will allow you (or algorithms) to predict how the next charge cycle will behave with any real accuracy. This is particularly true when the monitoring program does not know what the user will be doing next, or how often the user will be opening the freezer door to see if the ice cubes are frozen yet! So is there a better way? Nope.
Thanks. I guess I have just make do with the present state, and await further developments in battery technology. I just turned my laptop on, and that is more than 13 hours since it was last shutdown, and the current state shows as...
No, I don't use sleep...I shutdown. However, sometimes when it is inactive for awhile, it does got into hibernate mode. When that happens, I just press the on/off switch, and reenter my password and it opens where I had last left off.
@stapp This is the first time I have been into check 'Power setting'....so, this is default by the look of it. Everything is greyed out.
Untick Fast Startup and click OK or apply On Win 10 when you shutdown it's not a 'real shut down' it's a pretend one. It holds everything in a sort of suspend hybrid state so that when you start your machine up you say'' wow that is fast!!' With fast startup unticked when you shutdown it's a real shutdown (like on XP and Win 7) This may enable you to see if your battery lasts any longer when the machine is really turned off. Off course your machine will take a few seconds longer to boot now from a cold boot state.
OK...Will do...What about those sleep options, that I have at present? Should I get rid of those 3 for battery mode, that are there at the moment. Or, should I let them be?
Tarnak that is up to you the sleep settings/battery modes. Perhaps others may give their finding and settings on that as I don't use sleep. I just mention Fast Boot as I have it turned off as I find some things work better with it off, for example Shadow Defender. Also if I tell something to shutdown that is what I want it to do!!
