Recommended battery care practices
Recommendations for battery usage and storage are covered in the HP User Guides for each model.
Additional battery care practices are as follows:
- Store Li-Ion batteries between 20°C and 25°C (68°F and 77°F) with 30% to 50% charge.
- Do not disassemble, crush, or puncture a battery; do not short the external contacts on a battery; and, do not dispose of a battery in fire or water.
- Do not leave batteries exposed to high temperatures for extended periods. Prolonged exposure to heat (for example, inside a hot car) accelerates the deterioration of Li-Ion cells.
- Remove the battery if the notebook will be stored (turned off and not plugged into AC power) for more than 2 weeks.
- Remove the battery from the notebook if the notebook will be plugged into AC power continuously (via a wall adapter or docking station) for more than 2 weeks.
- Use the type of battery with the highest capacity (Ah) rating if the notebook will run high-end applications on battery power.
- Calibrate the battery based on the usage model. Under normal usage, batteries should be calibrated a minimum of once every 2 – 3 months; however, a battery that is rarely discharged fully should be calibrated about once a month.
- Keep the battery away from children.
- Use only the battery provided with the computer, a replacement battery provided by HP, or a compatible battery purchased as an accessory.
- Run the Battery Check in the HP Support Assistant once a month to maintain the battery.
Factors that contribute to loss of battery capacity
- Li-Ion battery cells suffer gradual, irreversible capacity loss with each discharge-charge cycle. Such aging occurs more rapidly as temperature and discharge loads increase.
- The self-discharge rate of a Li-Ion battery is higher if the battery is left in an unpowered notebook.
- During prolonged storage or non-use, the battery charge will decrease below its recommended low-voltage level.
- Leaving the battery in a depleted condition for an extended period accelerates the decrease in full charge capacity. Leaving the battery at a high level of charge in a high-temperature environment for extended periods (for example, running a notebook computer in a docking station under a heavy load) also accelerates the loss of capacity.
- Running high-end applications using the battery accelerates the loss of capacity. For example, playing 3D games lowers full charge capacity faster than using word processing applications.
NOTE: This is for HP Notebook PCs with Windows 7 and Vista.
How long will the battery last?
Users often ask how long should their battery last between charges, or why does one model of computer get better battery performance than another. There is no simple answer. Battery life will vary depending on the product configuration, product model, operating system, applications loaded on the product, power management setting of the product, and the product features used by the customer. For all batteries used in an electronic device, the maximum capacity of the battery will decrease with time and usage.
Power plans
A power plan is a collection of hardware and system settings that manages how your computer uses power. Power plans can help you save energy, maximize system performance, or achieve a balance between the two.
Maximizing the capacity and life span of the battery
It is important to be aware of ways that you can care for the battery in your notebook PC. There are conditions that may reduce battery run time and life span.
Bluetooth
All active connections will rapidly decrease your phone’s battery life. Here’s how to turn off Bluetooth:
- From the Home screen, select Settings
- Tap Wireless controls
- Unmark the Bluetooth checkbox.
Other useful tips to maximize battery performance:
- Only use location services when needed
- Turn off push email
- Minimize the use of applications
- Charge your phone whenever it’s looking low
- Turn off your phone temporarily if you’re out of coverage or use Flight mode – your phone will consume power when it’s searching for network
- Turn off Wi-Fi when you’re not using it
- Close running applications when not in use.
Well, here are some simple settings to ensure you squeeze the most juice you possibly can from your Sony Ericsson Xperia X10 Mini.
Screen
Touch screens historically use more power than non-touch screen, so the first thing you’ll need to d is lower the brightness levels of the screen.
- From the Home screen, select Settings
- Tap Sound & display
- Scroll to Display settings and tap Brightness
- Drag the slider to the left and tap OK when it’s at a brightness you can stand
