Extend tablet battery HP SF02XL Service life
1.Charge the battery! Consider keeping it plugged in for 12 hours before you unplug.
2. Switch on the optimized battery or power feature. You'll find this option — sometimes referred to as max battery mode — in your tablet battery system's built-in power management control panel. You can select the option to reduce the amount of time your inactive tablet battery stays on before powering itself down and going to sleep.
3. Remove the battery and clean the metal contacts. Wipe them with alcohol, ideally every two months, to ensure that the power transfer between the tablet battery and its battery is as efficient as possible. Allow the battery to dry thoroughly before replacing it!
4. Unplug any tablet battery accessories you aren't using. Even if they're not in use, accessories drain power from the battery.
