Is it possible to overcharge an iphone

There are many other factors, including extreme temperature fluctuations and your charging habits. The lithium-ion batteries in our phones chemically age and hold less charge over time. That's why your old phone doesn't stay charged for as long.

Android phone manufacturers, including Samsung, say the same. Most phones come with charging regulation options baked in for this reason. On iPhones running iOS 13 and later, Optimized Battery Charging reduces the amount of time your phone spends fully charged. Phone charger: This portable bundle packs a punch. Most devices are designed to work in a wide range of temperatures, say between 16 to 22 Celsius, but exposing your device to high temperatures regular above 35 degrees could damage it.

Apple for example will temporarily shut down your device if it gets too hot. The company suggests that "Charging the device in high ambient temperatures can damage it further. Thankfully it's not the same for cold temperatures and batteries are far more suited to dealing with the cold. You will probably notice your battery performance go down - cameras are especially prone to this on skiing trips, however the poor performance is normally only temporary and you should see usual battery life return once you get back to warmer conditions.

Battery memory is a pretty old concept that applied more to Ni-Cad batteries of old, rather than modern lithium-ion packs. So where you previously thought letting a battery fully dissipate before charging was best you now need to do the opposite.

A lithium-ion battery is best kept between 50 per cent and 80 per cent charged so as to use the charged ions and keep battery life prolonged. So charging in short bursts throughout the day is probably the best way to keep your phone going in both the short and long term. That's a lot easier with wireless charging. Both Android and iOS allow you to use Low Power Modes to extend the life of your battery over the day, allowing you to preserve your battery further.

While you can use any charger for a lot of phones, like Android devices, it's best to use the official one. These trickle charges can lead to higher ambient temperatures for your phone, which can reduce capacity over time.

Rechargeable batteries are also basically doomed from the start. This results in a gradual loss of their capacity, or ability to hold a charge. An Apple webpage about batteries cautions that the capacity diminishes after a certain amount of recharging, and that the capacity on li-on batteries diminishes slightly with each charging cycle.

Full discharges wear out the battery sooner than do partial discharges. That will help preserve the capacity of the battery. You should also keep your phone cool, as higher temperatures accelerate the loss of battery capacity. The moral of the story? According to Battery University , a website run by the company Cadex, charging your phone when its already fully charged keeps it in a high-stress, high-tension state, which wears down the chemistry within and does lasting damage.

In a brilliant and comprehensive Quora answer , tech author Jesse Hollington tells you everything you need to know about how your smartphone battery works: "Charging your iPhone overnight will not harm your battery in the slightest. You simply can't overcharge an iPhone, or any other modern electronic device, for that matter.
