- This report gives particulars on capability, cycle counts, and extra.
- In case your battery is nearing the top of its life, it may be changed.
Have you ever observed a decline in your laptop computer’s battery life? Does it randomly fall under 20%, leaving you scrambling for a charger? You possibly can run a report back to verify your battery’s general 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 very fact is that batteries are, by their nature, consumable know-how. All will inevitably degrade, no matter how they’re handled.

You will have heard about methods to maximise battery optimization, however I would not stress about these strategies. There is not any must fixate on unplugging your laptop computer at a sure level or monitoring the cost proportion 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 top of its lifespan. Here is how one can verify battery well being in Windows 11.
Tips on how 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 latest charging information. Let’s discover crucial metrics within the report.
Design capability
First, now we have 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 vitality, not cost.
Full cost capability
Now verify 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 verify on your battery’s general 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? Effectively, it is dependent upon the battery dimension, however for many small to mid-range batteries (45Wh, 48Wh, 60Wh, or 65Wh), if the complete cost capability has decreased by 15% or extra, you will possible be going through noticeable battery degradation.
A 20% loss in full cost capability is usually thought-about grounds for alternative, and you will possible discover a big loss in capability at that time. That being mentioned, it isn’t a tough rule. You is likely to be round that proportion and really feel like your battery is okay.
Cycle depend
Let us take a look at one other key metric: the cycle depend. This quantity data what number of instances you have used 100% of the battery’s capability.
If in case you have a 60,000 mWh battery, one “cycle” refers to what number of instances 60,000 mWh of vitality has flowed out of the battery — no matter whether or not that is (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 client laptop computer batteries are designed to final round 500 cycles, and it is round then that you’re going to possible see a 20% loss in capability. How rapidly you get to that proportion, nonetheless, is dependent upon your utilization habits.
Additionally: Should you ever turn off Windows Security? It’s tricky, but here’s my rule of thumb
Gentle workplace customers, who ceaselessly hold laptops plugged in, would possibly solely undergo a full cycle each few days. Over the course of three years, these customers would possibly solely attain 200 cycles, doubtlessly extending the battery’s lifespan by one other three years.
On the opposite finish of the spectrum, energy customers, players, or cellular customers who topic their batteries to extra cycles per week, together with an elevated warmth load, will see a quicker general 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 gadgets 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 latest battery drains. Observe that these numbers can fluctuate wildly as they symbolize completely different utilization patterns.
On the left, the length determine reveals how lengthy the battery lasted. On the precise, the determine reveals what that length 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.
Tips on how to exchange your battery
You normally needn’t purchase a brand new laptop computer for a battery alternative. Most mainstream laptop computer producers, reminiscent of Dell, HP, and Lenovo, supply alternative 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, it’s possible you’ll obtain a alternative at no cost.
