Battery Testing - A new chapter in my SP3 life?

[Michael Lovett]

So I've been one of those that doesn't seem to be able to get more than 3-4 hours battery time, even while following all the suggestions here.

So today I tried a test. Starting at 100% battery, I set the screen brightness at its lowest setting, turned sleep to "never", and left a stopwatch application running. After 8 hours, I still had 13% battery left.

So clearly, my battery is capable of lasting for a good deal of time. It's not "broken" out of the box.

Next up, repeat same test, with brightness at a minimally acceptable level, maybe 35 or 40% and see what that does. (By the way, other than "eyeballing it", how do you know what % of brightness you are at?)

This could be a slow slog but I'm determined to incrementally deduce how the heck I can get better battery life while using the SP3 for more than running "stopwatch", lol.

Just curious have you had any thermal shutdowns? have you refreshed at all? Especially since 8/19 FW update?

You can set a specific brightness in the advanced settings of the power plan.

Go to windows mobility center and you can see brightness % on the adjustment slider.
I have worked a lot on battery life on my i7, see comments in the other thread you started here.

I have never had a thermal shut-down, thankfully. Not sure what you mean by "refreshed"?

From the Charms bar> Settings> Change PC Settings, Update and Recovery, Recovery.

These are the options for reinstalling Windows. In my case I did a full reset about a month into owning my buggy, unpredictable SP3, and it turned it into a new device.
