Maybe one day it will be fixed, but given that this bug has been in place since Chrome 41, I’m not holding my breath. A look at one CPU core.įinally, there’s the “Frequency State Data” display, which I couldn’t get to do anything during my testing. Turns out this could be a bug related to Intel chips. Still, it can be nice to see an overview of what each processor core is doing. But I’ll be honest with you: there is a lot of data here, and probably more than you care to pay attention to. It’s a good way to see what’s going on with the processor. Idle state data doesn’t directly show the battery output, but rather the processor cores and what each one is doing. Playing with this will give you a better idea of what each value means, too.īack on the main power menu, you’ll also find the “Idle State Data” menu. Type the number of samples you want to use and then click the “Reload” button. You can also specify the number of samples in which to take the average by using the “Average Over” box at the very bottom. Binned Average: This combines clusters of data into a single, larger section of data, and then uses the average as the primary value.Moving Average: This essentially smooths out the battery discharge rate by using subsets of data and taking averages based on these larger sections of data.

Discharge Rate in Watts: This shows the battery’s discharge rate in terms of energy transfer, not just percentage.

Without getting overly technical, here is a quick look at what each of these values represent: It’s a line graph that displays three different values. The “Battery Discharge Rate” display is a little harder to understand. 1% at a time, so you can really see what’s going on. To take a closer look at any of the options, click their corresponding “Show” button.Ĭlicking the “Show” button next to the Battery Charge entry reveals two displays: “Battery Charge Percentage” and “Battery Discharge Rate.” The former simply shows the battery percentage drop (or gain if charging) over time, but in a much more granular way than you’ll get in the status bar-it breaks the battery drain down by. To get there, open a new tab in your browser and type the following address into the Omnibox: chrome://powerĪ barebones power menu shows you a few advanced options. That’s the case with the Power Menu, which shows you battery charge and loss over time, as well as CPU states and idle times. Like so many things in Chrome OS, many of the most powerful tools are hidden behind the scenes. Find Advanced Battery Stats in Chrome OS’ HIdden Power Menu Once the test has finished, it will tell you how much the battery drained in the specified amount of time, which can help you gauge how much battery life you’ll get overall under a similar workload. Just keep in mind that the value has to be entered in seconds when appended to the command. While you can do this for any value, it’s probably not a good idea to go for extreme amounts of time here-stick to minutes, not hours. In our example, the test runs for 30 seconds instead of 300. The default is 300 seconds, but you can change that time by appending a value in seconds to the end of the command, like so: battery_test 30 The command also runs a simple discharge test, where it records the amount of battery drain over a specific amount of time. The health represents the overall usable portion of the entire battery and shouldn’t dramatically change over time. You’ll also see the battery’s health, displayed as a percentage. First up, you’ll see the current battery state (charging/discharging) along with the remaining percentage of battery life. For more information refer to Dell Knowledge base article Battery Health Check.This command shows you a few stats. Perform a battery health test on the battery with the A/C adapter.

Try following the steps outlined in the following article: How to recover and reset the Chrome OS Try another A/C Adapter if one is available. When the battery does not seem to be charging: Note: You should always keep the charge on your battery above 1%, letting the battery completely discharge can be harmful to your computer and the battery may not charge from a completely discharged state.
