How to improve battery status on Windows 8 and Windows 10 by battery report
This function is built on PowerCfg command in Command Prompt. Users can use PowerCfg to create an energy report, in order to provide recommendations on the battery status and extending battery life.
How to create a battery report
Battery report in fact is created as a web file via only one single command on Command Prompt.
First, users need to open the Command Prompt window by right-clicking in the bottom left corner of the screen, or users can press the Windows key + X and then click Command Prompt in the displayed list.
Once you finish accessing to the Command Prompt, enter the next statement: powercfg/batteryreport. Immediately after pressing Enter to create the command, the system will save a battery report to the user account's folder at: C:UsersNAMEattery-report.html. The last thing to do is accessing the folder and double click to open it, with NAME is the name of the user, and note that you need to enter the name absolutly correctly.
Or users can access the Internet Explorer to paste the address above and access the battery report.
What is battery report?
Battery report is a simple HTML file divided into sections. The first section lets users know about the computer name, BIOS version, as well as if it supports Connected Standby or not and battery report creation time.
The next section will inform users about the source of the battery such as the battery model name, serial number, the chemical composition of the battery. However, the most important information that the users must pay attention to is the design capacity, full charging capacity and number of charging cycles.
For example, in the illustration below, the users can see the size of the battery design is 45,000 mWh - the real number is 45 337 mWh, when fully charged battery capacity is 41,000 mWh (reality is 41,073 mWh). These are the parameters in normal condition and therefore the users can easily detect the battery problem when either of above parameters decline.
Furthermore, the charging cycle can also tell how long the battery problems occurred. A charging cycle is calculated since finishing charging and use from 100% down to 0%. Or use battery from 100% to 50%, then 100% charged and discharged back to only 50% can be considered as a single charging cycle.
The third category in the battery report is Recent Usage. This report was created with the purpose to monitor the battery status within the nearest 3-4 days. Users can view the time the device starts operation, decommissioning and the remaining battery capacity at the present time as a percentage of the battery with mWh quantity.
Next is Battery Usage section. This section provides users a graph to observe battery deterioration over time. Just like Recent Usage, Battery Usage section can only display using data of the battery within 3-4 days ago.
The section below is Usage History, which will display status and usage time of the battery. Battery usage time is calculated with both cases: use source and use battery charger. These parameters can be deleted when users install Windows on this computer again.
Another section is Battery Capacity History, which allows users to see how the fully-charged battery capacity decreases over time compared to the design capacity.
The last one is the Battery Life Estimates with format display is a table estimated average battery life of each times based on way users use their computers.
The battery report does not provide users any instructions or recommendations as other Battery Care softwares. However, the advantages of the report is that it can provide a full range of in-depth information so users could see the "health" status of the battery, then decide effective safeguards or battery replacements.
