To those who get more than 6 hours....

how is this even possible my battery showing more capacity then the design capacity pic attached mines the LCE battery

Doesn't surprise me.. I am now convinced the LGC battery in the SP3 is far superior than the simblo

1,000 charge cycles is what some manufactures say is the standard for Li-ion batteries. 57% at 500 sounds like it's close enough.

My battery capacity started at 42157

Now says full 41093

That's after 107 cycles

Am sure someone on ere said you should calibrate your battery and then check report as it could be giving you wrong readings , they said let the battery run down to 0 then fully charge the battery with out using the surface then check report

Conditioning your battery will improve it. I had neglected my RT for a while and the level was down but after a few conditioning runs its back to 94% and holding.

I got the RT at launch in Fall 2012.

Actually that's quite common batteries are built a little over capacity to avoid complaints of being shorted.

I have an LGC battery too with 31 cycles and I'm averaging just over 9 hours with brightness set to 30% and 70% when plugged in. Brightness is the biggest factor with battery life; if I set the brightness to 50% or more, I'll average 6-7 hours of battery life. If I set the brightness to 10% or 20%, I'll average 10-11 hours.

Sorry if I sound like an idiot, but I have finally received my sp3 and wanted to know how you display battery information?

Thanks.

Any idea why I can't see some information in the battery report ? (like the remaining capacity, the design capacity, full charge capacity..etc)

Open Command Prompt in Admin mode and copy the following line and press enter:

powercfg /batteryreport /output %USERPROFILE%\Desktop\battery_report.html

Well, actually I don't consider 57% to be anywhere close to 80% as MSFT claims for 1000 cycles. Of course, I'm making a huge assumption that my battery will lose its capacity at the current rate which is 3% at 35 cycles.

I've just let my battery drain to 0 (well, not quite as it'll enter hibernate at 3% or so) and charged it back full. So it "should" be calibrated.

That is excellent for such old device.

How did you "condition" your battery? Thanks.
