HP Notebook PCs and Chromebooks - Improving battery performance

Learn how to get the most service and life from your HP notebook battery by following these industry-wide suggested best practices.

Note:

If you notice your notebook battery is swollen or deformed, go to Swelling or deformation of notebook battery (Windows only) for more information.

Swelling or deformation of notebook battery (Windows only)

To protect your hardware from potential damage, HP recommends that, if you are experiencing battery swelling, you discontinue use of the notebook until the battery can be replaced. You can contact HP to understand what battery replacement options are available.

Noticing a swollen battery: You might notice that your notebook battery has become somewhat deformed or swollen over time. In some cases, the battery swelling might be significant enough to impact other components of the system including the touchpad, keyboard, and chassis.
Not a safety issue: A swollen battery does not present a safety issue. It is the result of the generation of gases per the normal degradation of the battery cell over time. HP has worked closely with our battery cell suppliers and third-party industry experts to help minimize the potential for HP batteries to swell over time and to identify that swollen batteries are not a safety issue.
Discontinuing use: To protect your hardware from potential damage, HP recommends that, if you are experiencing battery swelling, you discontinue use of the notebook until the battery can be replaced. You can contact HP Customer Service to understand what battery replacement options are available.
Replacing a swollen battery: If a battery is under warranty, HP will replace the battery per the terms and conditions of the HP Worldwide Limited Warranty or applicable HP Care Packs. For batteries no longer under warranty, contact HP to purchase a genuine HP replacement battery.
Minimizing battery swelling: There are multiple drivers that can accelerate battery swelling. To help mitigate battery swelling over time, customers should use the HP Battery Health Manager settings found in the HP BIOS. Available on most HP Business Notebook PCs, the Battery Health Manager feature provides a number of options designed to improve battery longevity and performance for various use scenarios.

Conserve battery power (Windows only)

Use these tips to change the power consumption of the computer to conserve battery power.

Reduce the number of open applications. Each open software application uses memory and power, even when the application window is minimized. Close software applications to conserve battery power.
Reduce the brightness of the screen to the minimum readable level. Use the function keys to adjust the brightness or use the display settings in Windows.
Remove peripherals when not in use. External hard drives and other peripheral devices can draw power from your battery even when they are not in use. Disconnect peripheral devices when you are finished using them.
Reduce the speed of your processor. The faster your computer works, the more quickly it depletes battery power. You can extend the charge of your battery by slowing down the processor speed.
Turn off the wireless function. Wireless connections draw battery power. When wireless capability is not needed, turn it off. Press the Wireless On-Off button so that the wireless feature and wireless light turn off.
Change the power option setting. Select either HP Recommended or Power saver to conserve battery power.

Adjust power plans (Windows only)

A power plan is a collection of hardware and system settings that manage how your computer uses power.

Power plans can help you save energy, maximize system performance, or achieve a balance between the two.

In Windows, search for and open Choose a power plan to learn about, customize, and choose a power plan.

For more information, see Change power plans to meet performance needs (Windows only).

Change power plans to meet performance needs (Windows only)

Change how the computer uses power when plugged in or using the battery in Windows 10.

In Windows, search for and open Control Panel.
Search for power, and then click Power Options.
Select an option under Choose or customize a power plan.
To customize the selected plan, click Change plan settings, and then select the display and sleep settings when using the battery and when plugged in.

Note:

Notebook battery performance and capacity (Windows only)

The performance and capacity of laptop batteries naturally decrease over time. The way a battery is used daily can also affect these attributes.

Many factors can contribute to battery performance, including the following:

Battery cells suffer gradual, irreversible capacity loss with each discharge-charge cycle.
Temperature and discharge loads can impact battery performance and capacity.
Battery capacity can decrease even when the computer is unplugged from a power source and not in use.
During prolonged storage or non-use, the battery charge can decrease below its recommended low-voltage level. Discharging the battery below its recommended low-voltage level might physically damage the battery and result in the battery becoming unusable.

Note:
If the battery does not recover after charging for 30 to 60 minutes, the battery has most likely sustained physical damage and must be replaced.
Leaving the battery at a high level of charge in a high-temperature environment for extended periods can accelerate the loss of performance and capacity.
The computer generates excess heat during high workload or if it is not properly ventilated. This temporarily impairs the battery charge and discharge rate. The battery function returns to normal when it cools to an acceptable operating temperature.
To help maintain battery capacity, HP batteries are designed to discharge a small amount once fully charged. This is normal for most notebook batteries. The battery begins to recharge once the charge has dropped below 95%.
Using software for graphics processing or high-definition video accelerates the loss of performance and capacity. For example, playing 3D games decreases capacity faster than using word processing applications.
Your notebook configuration and power settings can impact your battery performance. This includes settings such as the following:
- Display brightness
- Backlit keyboard
- Display resolution
- Windows Power Plan
- Processor speed
- Type of storage, such as a peripheral storage

Adaptive Battery Optimizer (Windows only)

Adaptive Battery Optimizer is designed to maximize battery lifespan and is available on select HP OMEN and HP Pavilion Gaming laptops.

To confirm support for your laptop and learn how to configure the options, see HP Gaming Laptops - Introducing Adaptive Battery Optimizer, Designed to Prolong Battery Lifespan.

Use Battery Health Manager (HP Business Notebook PCs with Windows only)

This BIOS utility provides a number of settings designed to improve battery longevity and performance for select HP business computers.

For a list of supported computer models and BIOS updates to enable Battery Health Manager on those platforms, go to HP Business Notebooks, Mobile Workstations, and Mobile Thin Clients - HP Introduces HP Battery Health Manager To Help Optimize Battery Health.

Turn off the computer, and then make sure that the power cord is connected to the computer.
Turn on the computer, and then repeatedly press the esc key until the Startup Menu is displayed.
Press f10 to open the BIOS Setup Utility.
Using the arrow keys, select Advanced > Power Management Options.

The Battery Health Manager feature opens. If you do not see Battery Health Manager, go to the HP Customer Support Software and Driver Downloads page to update the BIOS to the most current version available.
Click the drop-down menu to select a Battery Health Manager setting.
- Maximize my battery health: Use this setting if the computer stays plugged in to the power adapter most of the time. This setting maximizes battery health by lowering the maximum battery charge level to 80%.
- Let HP manage my battery charging: Use this setting if the computer is regularly removed from the power adapter and allowed to discharge or over a year old. Charging behavior automatically adjusts to balance between maximizing battery health and maximizing battery duration.
After you choose a setting, click Save, and then exit the BIOS Setup Utility.

Battery care practices

Recommendations for battery usage, storage, and care.

Recommendations for battery usage and storage are included in the user guide for your computer. Additional battery care practices are as follows:

Store batteries between 20°C and 25°C (68°F and 77°F) with an 80 to 90% charge.
Do not disassemble, crush, or puncture a battery, and do not short the external contacts on a battery.

Warning:
Keep batteries away from children. Batteries can be a choking and poison hazard.
Do not leave batteries exposed to elevated temperatures for extended periods. Prolonged exposure to heat (inside a hot car, for example) accelerates the deterioration of battery cells.
For long term battery storage, do the following:
1. Charge or discharge the battery to 80 to 90%.
2. Place the notebook into ship mode per your user guide. See your notebook user guide to determine if your computer supports this feature.
  
  Note:
  For the steps to put a business computer into ship mode, see HP Notebook PCs and Chromebooks - Enable ship mode for longer term storage.
3. Check the battery charge every three months. If the battery charge falls below 50%, charge the battery to 80 -to 90%, and then repeat the steps in the user guide to return the computer to ship mode.
For best performance, use only the battery provided with the computer, a replacement battery provided by HP, or a compatible battery purchased as an accessory. If you have a choice of battery types to use with your computer, use the type of battery with the highest capacity rating.
To maintain the battery, run Battery Check using HP Support Assistant. Under normal usage, batteries should be calibrated a minimum of once every two to three months. However, a battery that is rarely discharged fully should be calibrated about once a month.

Go to HP Support Assistant to download and install the software. Run the test, and then calibrate the battery based on the results.
