- You’ll be able to run a report back to examine battery well being in Home windows 11.
- This report gives particulars on capability, cycle counts, and extra.
- In case your battery is nearing the tip of its life, it may be changed.
Have you ever seen a decline in your laptop computer’s battery life? Does it randomly fall under 20%, leaving you scrambling for a charger? You’ll be able to run a report back to examine your battery’s total well being and if it is time to exchange it. And no, you do not have to be a professional to entry this characteristic.
The actual fact is that batteries are, by their nature, consumable know-how. All will inevitably degrade, no matter how they’re handled.

You might have heard about methods to maximise battery optimization, however I would not stress about these strategies. There isn’t any must fixate on unplugging your laptop computer at a sure level or monitoring the cost share like a hawk. Your actions will solely have an effect on battery life a lot.
That mentioned, in case your battery is a shadow of its former self, it might be nearing the tip of its lifespan. Here is how one can examine battery well being in Home windows 11.
The way to run a battery report
- Within the Home windows search bar, kind powershell and hit Enter.
- Within the black textual content window that pops up, kind: powercfg /batteryreport /output “C:battery-report.html” and hit Enter.
- The system will ship an .html doc to the C: folder. Navigate to the folder in Home windows Explorer and double-click it to open it in your browser.
This report describes the title of your battery, its chemistry (possible both lithium-ion (Li-ion) or lithium-polymer (LiP)), its lifecycle place, and a few current charging knowledge. Let’s discover an important metrics within the report.
Design capability
First, we’ve got design capability, which refers back to the energy the battery may pump out when it was model new, in mWh (milliwatt-hours). This metric measures power, not cost.
Full cost capability
Now examine the metric proper under that. Full cost capability stories the battery’s present capability (additionally in mWh). The distinction between design and full cost is a useful metric to examine in your battery’s total well being. If the second quantity is drastically decrease, it means your battery’s capability has considerably decreased because it was new.

How a lot are we speaking? Nicely, it depends upon the battery dimension, however for many small to mid-range batteries (45Wh, 48Wh, 60Wh, or 65Wh), if the total cost capability has lowered by 15% or extra, you may possible be dealing with noticeable battery degradation.
A 20% loss in full cost capability is usually thought-about grounds for substitute, and you may possible discover a big loss in capability at that time. That being mentioned, it isn’t a tough rule. You could be round that proportion and really feel like your battery is ok.
Cycle rely
Let us take a look at one other key metric: the cycle rely. This quantity information what number of occasions you have used 100% of the battery’s capability.
When you have a 60,000 mWh battery, one “cycle” refers to what number of occasions 60,000 mWh of power has flowed out of the battery — no matter whether or not that is unexpectedly (going from 100% to 0%) or over the course of two days (going from 100% to 50%, as much as full, all the way down to 50%, and again as much as full once more).
Most shopper laptop computer batteries are designed to final round 500 cycles, and it is round then that you will possible see a 20% loss in capability. How shortly you get to that proportion, nevertheless, depends upon your utilization habits.
Additionally: Do you have to ever flip off Home windows Safety? It is difficult, however this is my rule of thumb
Mild workplace customers, who often maintain laptops plugged in, may solely undergo a full cycle each few days. Over the course of three years, these customers may solely attain 200 cycles, probably extending the battery’s lifespan by one other three years.
On the opposite finish of the spectrum, energy customers, avid gamers, or cell customers who topic their batteries to extra cycles per week, together with an elevated warmth load, will see a sooner total degradation of the battery.
It is essential to notice that each of those use circumstances are ‘legitimate’ methods to make use of your machine. You are not doing something incorrect by pushing your laptop computer to its limits, and, as I discussed above, batteries are finite units meant for use. Simply do not let your laptop computer overheat, and that features placing it in a bag whereas it isn’t powered off or hibernating.
Battery life estimates
This part stories how lengthy the pc estimates the battery will final based mostly on current battery drains. Be aware that these numbers can fluctuate wildly as they characterize completely different utilization patterns.
On the left, the period determine reveals how lengthy the battery lasted. On the correct, the determine reveals what that period time would have been when the battery was model new. If these numbers are dramatically completely different, it may point out that the battery has degraded considerably.
The way to exchange your battery
You often needn’t purchase a brand new laptop computer for a battery substitute. Most mainstream laptop computer producers, akin to Dell, HP, and Lenovo, provide substitute batteries, both as standalone merchandise purchased for particular fashions or as a part of a service plan. In case your laptop computer remains to be beneath guarantee, chances are you’ll obtain a substitute at no cost.

After all, when you do not need to ship your laptop computer to the producer or do it your self, there are third-party restore corporations that can do the duty for a charge. Simply remember the fact that they may not assure something past profitable set up.
