The iPhone 15 may still be more expensive, due to a major change
If people are not afraid of prices, then Apple has no reason to lower the cost of its products. Conclusion, the iPhone 15 may blow things up again. This next range should become the brand’s most advanced; much like the Apple Watch Ultra. But if the iPhone 15 will become more expensive, it is above…
The most expensive iPhone 14 is the best-selling
By unveiling the iPhone 14 range in September 2022, the Cupertino brand sparked a series of controversies, particularly regarding the prices displayed for its phones. None of the models in this range are sold below 1000 euros. Compared to the past range, the iPhone 14 models took between 100 and 200 euros more. Apple still…
Effects of Cold
Prolonged exposure to cold temperatures also has a big impact on battery performance and safety. When temperatures drop the internal resistance of the battery is increased. This means that it requires more effort by the battery to charge, in turn lowering the capacity. However, it is important to note that the loss of capacity also…
Effects of Heat
When temperatures increase this affects the chemical reactions that occur inside a battery. As the temperature of the battery increases the chemical reactions inside the battery also quicken. At higher temperatures one of the effects on lithium-ion batteries’ is greater performance and increased storage capacity of the battery. A study by Scientific Reports found that…
Battery life reduces at higher temperatures
Even though battery capacity at high temperatures is higher, battery life is shortened. Battery capacity is reduced by 50% at -22 degrees F – but battery LIFE increases by about 60%. Battery life is reduced at higher temperatures – for every 15 degrees F over 77, battery life is cut in half. This holds true…
Wide temperature variations
Battery charging voltage also changes with temperature. It will vary from about 2.74 volts per cell (16.4 volts) at -40 C to 2.3 volts per cell (13.8 volts) at 50 C. This is why you should have temperature compensation on your lead-acid battery charger or charge control if your batteries are outside and/or subject to…
HOW DOES TEMPERATURE AFFECT BATTERIES?
Temperature effects on batteriesThe main capabilities of batteries that are affected by temperature are performance, lifespan, and safety. However, the way that these metrics are affected depends on the temperature, high heat changes a battery in different ways than if it was very cold. First, let us focus on how high temperatures can affect battery…
