Battery Drains While Shutdown

Hello Amit.

Thank you for your thoughts 

I have tried your idea many time - I just do it out of habit now lol

It doesn't make any difference to the battery leakage for me.

I even went through a stage of detaching the keyboard before shutting down. Turning off the docking port and other ports in the BIOS settings - just to see if they were the problem of leakage - full deep dive on this issue. 

Again thanks for your thoughts

hi Guys... try this :-

When you shutdown your surface pro, keep an eye on the keyboard back light, and don't close the machine till that light is ON.

What I figured that even though the screen looks like the machine is shutdown, it does not until about 2-3 mins of screen getting OFF. So hold on packing your machine until the keyboard backlight is gone completely. If you do that the machine doesn't leak any battery. At least this has been working perfectly fine for me.

Just make sure to tap on keyboard to make sure the backlight is gone completely, because the backlight timesout as well and it may look like that backlight is gone completely. so press keys to be sure.4

Thank for the tip on 'limit battery mode' Jay.

I have tried every solution on this and other sites,to no avail.

I live on a sailing boat so use of electricity is important ... ever volt counts. So charging my Surface 4 and then having it drop 15 to 20 percent every 4 hours was painful. At least now if I forget and leave it plugged in it will only charge to 50% - been very useful.  

I was going to ask if there is a way to limit the battery to 20% or anyway to purely run of the mains and not charge the battery at all, anyone know if this is possible? 

Also has anyone tried a different OS (other than W10)  after the problem occurs would be interesting to hear the results. I downloaded Windows 7 but haven't tried installing it. Tooo risky at the moment as this is now my only computer for my business. 

Let me know you thoughts people and thank you.

PS Sort it out Microsoft  (angry face emoji)

Thanks, Mark.

I suppose it is still possible that your new battery was defective, but your experience unconvinced me that this is a hardware problem.

In my case, I noticed the problem as a minor drain that became, as you now report, a 10 percent drain overnight with everything done that a user can do to make sure the device is completely powered off.  That got steadily worse over a few months until the battery completely failed and would not charge.  So I replaced the machine with a Pro 6.  Battery drain on it overnight is about 3 percent when shut down.  That's with Windows fast startup enabled.  I disabled it just now to see tomorrow what the battery drain is.

By the way, to prolong the life of my new Surface, I keep it in battery limit mode when I expect to be where AC power is readily available.

Hello Jay,

Thank you for your interest. Yes, I had read many articles and can confirm that I had taken the necessary actions to ensure that the SP4 was truly/fully powered down. It did/does not drain fully overnight, but from 100% charge it would lose between 20% and 30% overnight. I would log on the next day just to confirm the battery charge percentage and then fully power down again - the result being another 20% - 30% being 'discharged' overnight.

When the SP4 is being used on battery the battery life is good.

There must be a solution to this. Apart from this fault I love my SP4 - but it really is a big usability issue. Are there any reports such as Battery or Other that you would like me to make available to you? If you want to arrange the courier I would be willing to hand over the SP4 for a period of time to help identify the issue...

Regards,

Mark
