Windows 10: Battery report remaining capacity over 100%

sometime ago I was playing a game that I have been playing for 3 years with no issues, suddenly it crashed. I ran it back again, while connecting the charger and after sometime the laptop gave me a battery warning even though it was already connected, and when I checked the battery, it was at 100%. I didn't disconnect it because I was still playing the game and my battery drains rather quickly when playing it. Suddenly, the laptop went off, and when I turned it back on it was stuck on 0% and not charging no matter how long I leave it on. I used the original charger and even tried my mother's i

Battery Report

Hi jon_556, my name is John D. an independent advisor happy to help you with this.

Regarding the battery report showing a 10000% capacity remaining, this is likely an error or glitch in the system. It's not possible for a battery to have more than 100% capacity.

There could be a few reasons why the battery report is showing an incorrect capacity number. It's possible that there was an error in the command used to generate the report, or there could be a problem with the battery itself or with the computer's power management system.

To troubleshoot this issue, I would suggest starting with some basic troubleshooting steps such as:

> Restarting the computer and generating a new battery report to see if the issue persists.

> Checking the computer's power settings to ensure they are set up correctly.

> Running a battery diagnostic test to check the health of the battery.

> Updating the computer's firmware and drivers to the latest versions.

I hope this information is helpful to you.

Best regards,

Windows 10 battery report - Full charge capacity exceeds design capacity

I've replaced the battery twice on a Sony Vaio SVS15 with an aftermarket brand and have run into an odd result in Windows 10 battery report.

This shows up and slowly increases(full charge capacity) after following each of the battery manufacturer's recommendation to discharge the battery completely to allow software estimates' re calibration. On initial install, the capacities match.

With the first aftermarket battery:

After fully charging to 100%, then unplugging the charger, the battery will reflect 96% within about a minute. It then seems to discharge much faster than the estimates given by Windows. At the 10% mark, the system shuts down unexpectedly, completely drained.

Second aftermarket battery:

Intermittently, it shows 96% and not charging - I can unplug the charger and back in to bring it to 100%. Upon reaching 10% remaining (10 minutes remaining estimate), it'll run for another couple minutes, then lose power.

Are there other ways to re-calibrate a system to properly report battery life, or could these simply be two faulty batteries?

 

Battery FULL CHARGE CAPACITY Reset

Yves,

"Full charge capacity" means the capacity that the battery is managing to achieve. It is not a limit set by Windows or anything else; it is merely a reading of what the battery can actually do. You can use the comparison of Full charge capacity with Design
capacity to decide when to buy a replacement battery [I do the same regularly].

Full charge capacity will always decrease over time as the battery wears out. This is a chemical phenomenon not a Windows-imposed characteristic.

Windows display of "Fully charged [100%]" means - the battery is currently at 100% of what it is able to achieve. In other words, "Fully charged [100%]" is relative to Full charge capacity.

Sometimes, you can find that cycling through the battery three times** can improve the Full charge capacity a bit.
On at least one of my batteries, the maker recommends doing this every three months. But doing so is using up even more of its remaining life so you can complete this procedure only to find that you are worse off afterwards.

** In other words, loop through this three times -

• remove the AC power
• use up the whole charge by using the computer
• recharge fully
