Battery drains ALOT when in sleep mode

Question

I use my Surface Pro a lot and in the last two weeks I've noticed the battery drains by a lot even when I put it in to sleep mode. For example, I went to bed with my computer at about 56% battery and when I woke up 8 hours later the computer was at about ~6%. Similarly, I had my Surface Pro charged at 100%, then I didn't use it for about 24hrs and the battery was completely dead.

I've looked around and I see that theres something called connected standby that might be the issue. How do I go about getting my Surface Pro to how it was prior? It's really frustrating. Also, my surface pro is completely updated to my knowledge.

Hi Ian JD, 

We appreciate for raising this concern to us. Were there any changes made prior to this issue? If you are experiencing battery drains during Sleep mode, you may try the steps below.

For the meantime, you may try these steps might help fix the issue: 

Run SDT or Windows Updates. 

• Updates have fixes to common problems, or issues. For SDT - Surface Diagnostic Toolkit and For WU: Go to **Settings > Update & Security > Windows Updates > Check for updates.**Tip! Restart the Surface after installing updates.

Check the Power mode slider.

• On applicable models, the Power mode slider is found by clicking the battery icon on the Windows taskbar. For best battery life, the slider should be set to Recommended. If you need to use the device for an extended period of time while on battery, the slider should be set to Battery Saver.

Run Power troubleshooter.

• Surface devices have a configurable Power mode defines the preference between Best battery life and Best performance. The setting is configured separately for when the device is plugged and when it is on battery. This allows to set the device to Best performance while on PSU and for it to automatically change to a different setting, like Recommended, while on battery.Open Settings > Update & security > Troubleshoot > Power and then select Run the troubleshooter.

Check Battery saver Settings.

• This troubleshooter will automatically detect and fix these potential issues Open **Settings > System > Battery.**Check that Turn battery saver on automatically is enabled and that it is set to at least 20%. Check that Lower screen brightness while in battery saver is also enabled.

Check App usage.

• Unnecessarily running programs can cause slow system behavior and affect overall stability of the PC. Open Settings > System > Battery and then select See which apps are affecting your battery life. From Time period, select 6 hours, 24 hours, or 1 week depending on which period is closest on reported problem. From Show, select Apps with usage. Looks for apps that have high battery consumption. If there are apps with high usage that is not using, should close the app. If the apps start automatically, open Task Manager and then select the Startup tab. The customer can disable any apps that they don’t need to start automatically.

Choose or Customize a power plan.

Tap the Battery icon on the taskbar > choose Power & sleep settings > Related settings > Tap Additional power settings > Tap Create a power plan > Under Create a power plan start with an existing plan and give it a name. (  Automatically balances performance with energy consumption on capable hardware). > click next > Choose the sleep and display settings that you want your Surface device to use.

Hi, there were no changes prior to this issue arising. I just used it normally then suddenly this happens. I've tried everything you've mentioned including the updates, battery settings, plans, etc. but still no changes. It may be getting worse. I kept my surface pro charging over night so it was 100%. I unplugged it at around 8am and at 12:30pm it had dropped down to 62%. I'll send a battery report but is there anything else I could do?
