Study Notes

Mobile devices rely on batteries to function when not connected to a power source, but battery capacity decreases over time with each charge.
To save battery life, be aware of device reception and enable airplane mode when outside of signal range.
Airplane mode disables cellular, Wi-Fi, Bluetooth, and GPS radios, saving battery life on mobile devices.
Check battery usage on mobile devices under settings to identify high-consuming applications.
Batteries may swell over time and should be replaced if damaged or showing signs of swelling.
Mobile device screens are commonly made of glass, and broken screens require replacement of the entire display.
When charging a mobile device, check for dirt or damage to the charging interface and cable, ensuring they are functioning properly.
Liquid damage is not covered under device warranties, and liquid contact indicators turn color when in contact with liquid, indicating potential damage.
Water-damaged devices should be powered down immediately, disassembled, and left to dry in a dry area before attempting to power on.
Devices should be kept away from water and extreme heat, as both can cause damage.
Mobile devices have sensors that monitor temperature and automatically shut down if they get too hot to prevent damage.
