Batteries function best at room temperature, conditions such as low or high temperatures, dust and humidity can affect the performance of electronic devices.
Cold is always a threat for the battery life of our electronic devices, such as cell phones and computers. Cold can reduce their batteries’ effectiveness and damage internal components that make them work, although some of these damages can be temporary, the risk of a permanent damage can be high if precautions are not being taken before its use.
Talking about cellphones, low temperatures can shorten the battery life; it increases the internal resistance and diminishes the capacity. The performance of a battery drops drastically at low temperatures, most batteries that would provide 100% capacity at 80° F will typically deliver only 50% at 0° F. Batteries achieve optimum service life if used at 68° F or slightly below.
Computers have to be kept in a specific environment to function efficiently. If computers get too cold when left powered off, their components can be damaged upon boot because the electricity heats the circuit. As electricity travels through a circuit, it heats up rapidly and causes the matter to expand. Rapid expansion, when close to matter that remains the same size, distorts it; this can bend or break components.
It is recommended to let computers heat to room temperature before turning them on. Laptop displays are especially vulnerable to cold weather as they have liquid crystal that can freeze.
The ideal operating temperature of a computer ranges from 60 ° F to 82° F, though it should be as close as possible to room temperature, 72° F. Laptops should operate between 50° F and 95° F.
Other factors linked to weather that can affect our devices are excessive humidity or dry air that can exaggerate the effects of extreme temperatures on computer components; cold and humid areas create condensation and water, which can create a short circuit, affecting electrical components.
Tip: Warming a cell phone battery in your jean pocket might provide additional run-time in the winter.
