Charge Lenovo ideapad c340-14iwl battery notice

When the battery power is low, charge your battery by connecting your computer to ac power.
The battery is fully charged in about four to eight hours. The actual charging time depends on the battery size, the physical environment, and whether you are using the computer. If the power adapter shipped with your computer supports the rapid charge function, the battery is 80% charged in about one hour.
Battery charging is also affected by its temperature. The recommended battery temperature range for charging the battery is between 10°C (50°F) and 35°C (95°F).
Note: To maximize the life of the battery, the computer does not start recharging the battery if the remaining power is greater than 95%.

Dell xps 13 9310 Battery Settings Introduction

Dell Power Manager allows you to select a Battery Setting that is optimized for specific computer usage patterns. For example, some settings focus on extending battery life, while others provide fast charge times. Available settings may be limited, depending on the battery. Possible battery settings include:

    Standard - Fully charges the battery at a moderate rate. This setting provides a balanced approach to extending battery life while still providing a reasonably fast charging time. Recommended for users who frequently switch between battery and external power sources.
    ExpressCharge™ - Quickly charges the battery using Dell fast-charge technology. Recommended for users who need the battery to charge quickly. If the computer is powered off, then the battery typically charges to 80 percent within one hour and 100 percent in two hours. Charge time may be longer if the computer is turned on.
    Primarily AC Use - Extends battery life by lowering the charge threshold, so that the battery never charges to 100 percent capacity. Recommended for users who primarily operate the computer while plugged into an external power source.
    Adaptive - Automatically optimizes battery settings based on the user's typical patterns. Recommended for users who want to "set it and forget it."
    Custom - User selects when the battery starts and stops charging. Recommended for advanced users.
