In hypothesis, it ass be represented by a single number but, in practice, literally hundreds of factors can shorten or lengthen endurance. That's frustrating if you're trying to gauge the stamp battery life and health of your notebook, especially if you're trying to determine if it's time to buy a new laptop.

Windows has a secret feature named Battery Report that commode service. It's what we use patc testing notebook endurance at PCWorld. Here's how to access Battery Report and understand what it reveals you about your laptop.

How to create a Battery Report card

Battery Paper is not a new feature, but it remains under-the-radar because there's nary way to access it through Windows' settings menus. You can only if produce a Battery Report done the Command Prompt. Here's how to behave it:

• Perform a Windows Search for CMD or Command Prompt. You'll see Command Prompt appear and the search results. Open it. Alternatively, you can find Command Prompt recorded under Windows Arrangement in the Windows Start menu.

How to use Battery Account to estimate bombardment life

The Battery Report tail end be used to gauge battery life in a couple of shipway, merely most people will want to curl to the bottom of the report where you'll find the Battery life estimates section.

This does the math calculating how long the battery could last supported how long you've used it every day or week. The calculate is handy because you don't have to to the full drain the shelling.

Contain a take the Active column under At Full Turn on. This will evince a ensue formatted in hours, transactions, and seconds. If the column says 4:56:22, for instance, that means the electric battery was estimated to last four hours, 56 minutes, and 22 seconds.

You will besides notice the log lists At Plangent Complaint and At Design Capacity. The At Full Charge column is the estimate you want to pay attention to, as it creates an estimate based on the maximum charge your laptop's battery can handle right now.

The At Aim Capacity column creates an judge based on the maximum battery charge of your laptop when it was new. This is a useful comparison for an older laptop.

The log is not perfect. The estimate is based on how you used the battery in the past and so it will be off if you change how you use the PC in the in store. Even a limited change, like switch the web web browser you use, can cast the calculate.

Battery report's math can also prove a bit…odd, at times. You testament see errors when a system is used for solitary a short period of time or in brief bursts passim the day. You whitethorn as wel note errors if the system is not exploited at all for different weeks.

How to use Barrage fire Report card to measure battery life

The battery life idea is helpful for a quick glance, but you'll need to go deeper if you want an accurate result.

Have a look at the Bombardment exercis subdivision of the report. This shows you how the battery was actually used in the concluding triplet days. You can taste to piece together stamp battery life history victimisation these snippets, but it's leathery.

You can only disc an right result past forcing your laptop computer to discharge its stallion battery in one give way. Information technology's possible to do this while using the laptop usually, but it's easier to use a video, script, or benchmark that tail run unattended. Hera's a few suggestions:

• A YouTube video that's 10 hours long, operating theatre longer.
• Use up the Basemark Web 3.0 benchmark. Check the benchmark's configuration options and turn on Battery Life mode, which endlessly loops the benchmark.
• Use iMacros to make over a custom web browse macro and then use the loop boast to run the macro until the battery is drained.
• Usance a program like Macro Registrar to create a loop that repeats infinitely.

Also turn out all rest and hibernation features, including those that turn off or dim the display.

Starting line your chosen test and wait until the laptop reaches its critical assault and battery state. It will mechanically power off. Connect the laptop computer to power, turn it on, and run the battery report again. The Battery usage segment of the report testament tell you how long the battery endured.

Running this test will give you an accurate endurance baseline. You can comparison it to similar tests from other masses who own the same system, or you can run the trial every month to see how barrage fire life holds up over prison term.

How to use Barrage Report to measure battery health

Battery Report offers two Sir Thomas More ways to decide if your battery is terminated the hill.

The first is Cycle Count, which you'll determine near the top of the report under Installed Batteries. Cycle count is an estimate of how many times your laptop computer's full battery mental ability has been discharged.

This is accumulative: one bicycle can mean the battery was discharged away 20 percentage fivesome times, operating room 100 percent once. A typic laptop battery should handle several hundred charge cycles in front in that respect's any meaningful change in battery mental ability. Most can handle 500 to 1,000 cycles before shelling capacity becomes a job.

You can as wel examine the Battery capacity account section found halfway done the report. This provides a log of plumbed battery capacity and too, for convenience, shows the battery's designing capacity, which is how so much great power the battery should hold if it performed as motivated.

Many new laptops will show a afloat charge capacity that's a little higher than the purpose capacity, but the full charge capacity testament decrease as the bombardment ages. The laptop above, for instance, is approach its tenth natal day.

A gas-filled charge content that's 20 pct lower than the original design mental ability, operating theatre lower berth, indicates an experient shelling. There's nothing to stop consonant you from operative a bombardment into the ground, though. A modern laptop battery will stop workings entirely long before its full charge capacity reaches zero.
