I'm in the UK and also experiencing degradation as well as rapid discharging.

When it gets to 6%, it turns off. I managed to get this report done just before it died.
So that's (with only web usage) from 100% to off in 2 hours, 24 minutes. Bluetooth off, Location off, WiFi on and for some reason, flight mode also on. Yes, wifi works with flight mode on.
I've now got 69.5% of the designed battery capacity. Looking through my history, I have had times where the capacity has gone up again.
I'm wanting to try the 'run it always on battery' thing as much as I can however I do NEED my surface pro 3 for work, in places where I won't have AC power to connect to. There's also the fact that it's on standby a lot of the time and not fully off, so it
will drain in my bag when taking it places. You can't turn it fully off.
I'm doing the update now, strange that it doesn't auto-install, and will see what that does to the issue.
I am lucky enough to have an extended warranty as I bought mine from John Lewis who do a 2 year warranty as default on all electrical goods and occasionally a third year of cover on some items. However, due to me NEEDING this for work, I haven't taken it back
yet even though there are other issues. 90% of the time, I turn my surface on and it has no idea what time or date it is. The type cover will occasionally completely refuse to work and I have to perform a chained volume button/power button reset and reset
the system. Occasionally it will also not turn on and I have to do several chained resets to get it to start up.
If all of this does not get better, I may be forced to return it and go back to dual-booting on apple equipment.
I have a W10 phone (Nokia 930) which also suffers extremely badly from battery life going through the floor. Could it actually be true that MS just can't program an OS that doesn't consume the souls of it's battery?
Their suggestions for that were to turn everything off and not use any smartphone feature whatsoever. One step away from putting it in the bin and going back to the days of landline only communication.
I'll be back if I discover anything, I've subscribed to this thread as I want to see what everyone else's experiences are. It is clear I do not have the insane degradation other people have, I would love to know their battery cycle numbers to go with such insane
battery failures, and to read of anyone else's troubles or suggestions of what to do in the UK. I've read about the class action lawsuit brought against MS in the US, I am keen to see what happens there and if it can have any bearing or effect in other countries
where the SP3 is sold.
What is certain however, I won't be buying another MS product until something big is done to address their hardware issues.
