Battery drain issue

Hi there. I wouldn't worry about being a nuisance. They sell it with an advertised price, and that's what it should be.

In the meantime,

Keep Battery Saver on

Keep screen brightness as low as you can

Go to Start button, type "Control Panel", open it go to Hardware and Sound > Power Options, then whichever (pref Battery Saver or Balanced) is selected, go to "Change plan settings" (on the right in blue) > Change advanced power settings" (one from the bottom in blue) > click the + by Processor power management then "On Battery", change to 95% (this basically stops it giving a turbo boost to the processor every time you ask it to do something. If you notice a slow down, change it to 99%

Hope it helps a bit.

I got rid of mine and got a HP Spectre x360 11th gen i7 on the promise that it does 12-14hrs (it doesn't - again, about 5 hours of real world use)

The grim reality is this - battery stats from manufacturers and even reviewers measure battery life on the basis of minimal talks rather than real world work. Imagine if car manufacturers gave fuel efficiency stats on the basis of a parked car with the engine running!

Actually using a laptop as intended - with wi-fi on, accessing email, a little editing, using office and Google workspace and the odd zoom meeting, I've never found a Windows laptop to give much more than 6 hours.

When I travel and use it to read or watch a film with flight mode on, yes a laptop will tend to do to 9-10 hours.

Frankly it's mainly an Intel issue - they just can't seem to make power efficient cores, but might up their game with the new Macbooks, and on the other hand Windows is very bulky and inefficient because it's made for a thousand and one laptops and other machines.

Having spent years trying to get Windows laptops to get the battery life they advertise, the only thing I can say is to put the power plan on settings to best efficient and always use battery saver. Keep the screen brightness low and close any applications you're not using.

I actually tried to analyze the battery usage by reformatting my SP7. I realized the battery goes well for the first few full charging. It then started to get lower and lower battery life. Probably there is latest driver that drains the battery life 

As for performance issue, if I set the power setting as balance all the time, whenever the battery life goes below 50%, the CPU performance drops a lot.

My brand new Surface Pro 7 lasts 3-4 hours. I'm just browsing the web and watching Youtube. No other downloads in the background, and no apps running.

Below is another Microsoft resource that might help improve people's battery life:

System File Checker is a utility in Windows 10 that checks for problems with files on your computer. To run it, follow these steps:

• Make sure you've installed the latest updates for Windows 10, and then restart your machine. To find out more, read Update Windows 10.
• In the search box on the taskbar, type Command Prompt, and right-click or press and hold Command Prompt (Desktop app) from the list of results. Select Run as administrator, and then selectYes.
• Type DISM.exe /Online /Cleanup-image /Restorehealth (note the space before each "/"), and then press Enter. (**Note:**This step may take a few minutes to start and up to 30 minutes to complete.)
• After you see a message that says "The operation completed successfully," type sfc /scannow (note the space between "sfc" and "/") and press Enter.
• After you see a message that says, "Verification 100% complete," type exit.

Hi MSP2020,

I have read thru this entire process and trying to figure how this is going to actually help with the battery issue(s)? What is the reasoning behind this potential help/fix in your opinion? Or is there a tech webpage that you came across that directs you to this process to help with the battery issue(s)? Just trying to wrap my head around this and really understand how this would provide better battery life.

Thanks
