Design Capacity is the original maximum charge of your battery, while Full Charge Capacity is how much charge your laptop battery is capable of holding now. If these two numbers are pretty close, then you have a healthy battery.
But if the Full Charge Capacity is much lower than the Design Capacity , then your battery's health has dropped significantly. The Cycle Count shows you how many times the battery has gone through a charge.
With a high cycle count, your maximum capacity will likely be lower than the original level. Below this, you'll see some information on recent battery usage, which can help if you need to troubleshoot something specific. To get more info, check out some Windows apps to analyze laptop battery life.
There's a chance that when you generate the battery report in Windows, it won't actually include a cycle count. You can see this in the above image, which just shows a dash instead of the right number. If this happens to you, first make sure that you've updated all the drivers for your computer.
This problem can arise when Windows can't interface with your computer's hardware properly, meaning that current drivers are important. Pay particular attention to the battery driver, as well as the chipset driver.
After installing any available updates, reboot your computer and try running the battery report again. In case updating the drivers and BIOS doesn't work, you should next try installing the PC management software provided by your laptop manufacturer. For example, on a Lenovo machine, you can install Lenovo Vantage.
In addition to handy functions like updating drivers, these apps can display system information. This should contain information about your battery; hopefully it will include the correct battery cycle count too. Now you know how to check your laptop battery's cycle count to see if your battery is healthy. Don't fret too much about battery cycles; using your battery is a natural part of having a laptop.
Lithium-ion batteries are expensive. Very expensive. You read that right. Is buying a SimpliPhi battery a better idea than just buying and replacing the Trojan battery as you go?
Pretty amazing, right? Bottom Line: With an ultra-long lifespan and incredible DOD, lithium batteries can be just as cost-effective as cheaper lead-acid batteries. However, they still suffer from high sticker prices. Not nearly as popular as lead-acid or lithium batteries, you might be surprised to learn that nickel iron batteries have been around for over years! How much longer? Well, Iron Edison — a major manufacturer of nickel iron batteries — estimates their batteries will last 30 years with proper maintenance.
Similar to lithium batteries, nickel iron costs much more than lead-acid up front, but their much longer life cycle means you will get more use out of them. Despite its high price, the Iron Edison batteries are by far the most cost-effective batteries on our list, thanks to their ultra-long lifespan and mid-level price. The battery specs above assume that you maintain your batteries perfectly over their lifetime.
In reality, though, there are a handful of considerations that affect the lifespan of solar batteries, including temperature, maintenance, and your regular depth of discharge DoD. Choosing exactly how many batteries you need and how far you will discharge them is, to an extent, a balancing act between upfront costs and long-term value. High temperatures allow the chemical reactions to occur more quickly and improve performance, but that same high performance causes faster degradation of the battery itself and forces a shorter lifespan.
In essence, that 10 degree difference causes 2x the wear! The same goes for any battery, though lithium batteries can handle higher temps than lead-acid. When you exhaust the battery of a fully charged iPhone, you complete one battery cycle.
In reality, rarely does anyone charge and use their iPhones like that. So, let's take a look at a practical scenario, shall we? First and foremost, we'd like to point out that you'll only be able to view this data if you're sharing iPhone analytics with Apple, which most people do. If you don't, you need to turn this on and wait for two days before you go ahead with these steps. You have what you needed.
We had to use the Notes app since there's no way to search for a specific line of code within the log-aggregated file. Of course, you can scroll and find it yourself, but this will take a lot of time and effort.
