Windows 10: Battery Percentage estimate does not change

When I use my computer and mouse over the battery icon in the statusbar to see the percentage I have left, it does not change even though it should with use.I can force my computer to give me a new estimation if I turn on and off battery-saver in the notification center quick-actions, or if i put my computer to sleep and wake it. But then the percentage still stay stuck on that estimation unless I do that again.I tried reinstalling relevant drivers from my laptop's support website but the drivers are quite old since my laptop is old but was designed for windows 10. I tried uninstalling and r

Battery life estimates wrong

I have a Lenovo IdealPad and was reading a couple other forum questions about their laptops having battery estimate problems. These ranged from a loss of capacity after being off over night, such as mine losing over 15% even as the laptop was shut down overnight.
To a rapid drop which serious affects the estimated time left of a charge. I mean for example if using my laptop and it estimates my life as say 60% which translates to 3 hours 40 minutes but then 15 minutes later I am at 50% and 2 1/2 hours left? Doing the
same tasks and haven't changed brightness or anything?

This makes the battery estimates pretty much useless and how can I go from 87% capacity when I shut down my laptop to 70% capacity in the AM when I boot up? How can I loose over 15% capacity when the PC is off? Either some of us have some serious parasitic
drains on batteries and/or we have some serious issues with Windows being able to determine battery capacity. I've used laptops for years and for the most part battery life estimates have always been pretty stable and accurate. But lately I have noticed that
many laptops only show percentage left and not time left by default. Is this trying to conceal a inaccurate system? When I am charging my battery the estimates to full charge seem very accurate. So why are discharges so bad, that we now resort to percentages
rather then time ?

Incorrect Battery Report, no estimate available

Hi,



Thank you for writing to Microsoft Community Forums.



I would like you to know that the battery estimate report is generated as per the sensors that are present within the laptop to sense the battery. It could be an issue with the sensor and that could be the reason you are receiving a false estimate.



I suggest you to try updating the battery drivers, generate a report and see if that makes any difference. Please follow the steps mentioned in the article

Update drivers in Windows 10 and update the
Microsoft ACPI-Compliant Control Method Battery driver. The ACPI driver is responsible for the power management and Plug and Play (PnP) device enumeration.



If the issue persists, I suggest you to get in touch with the laptop manufacturer and have a check with the battery and the battery sensor.

Does Windows10 Have a Built-in Setting for Showing Battery Percentage?

Hello, *Smile

If it may help any, you could enable this below to see the battery percentage and remaining time like below from the battery notification icon on the taskbar.

By default, the percentage doesn't show unless you hover over or click on the battery icon, but the battery icon does show a bar on it that reduces as battery life reduces to help.
