Expert explains crucial reason why you should never charge an iPhone to 100%
The tech expert has explained the important reason why
Many iPhone users like to get their phone charged up to 100% battery.
It’s satisfying to leave the house knowing that your device is fully charged, meaning it will last as long as possible.
However, one expert has explained a crucial reason why you should never charge an iPhone that much.

According to tech expert Greg Wyatt Jr, on his YouTube channel, Apple Explained, regularly charging your phone up to 100% isn’t something that Apple says you should do.
In a video, the expert explained that the type of batteries used in most modern electronics, including the iPhone, is lithium-ion.
The capacity of these batteries are “only good for a certain number of charges, or cycles, before it begins to degrade”.
You can find out for yourself how much your battery has degraded by clicking onto the battery settings on your device and tapping battery health.
Wyatt said: “Obviously we want to prevent our batteries from wearing out as much as possible, which is why charging all the way to 100% and allowing the battery level to drop down to ten percent or less is considered bad practice.
“These deep discharges exhaust the lithium battery cells faster than charging to eighty or ninety percent and getting it back on its charger by the time it reaches thirty or forty percent.
“This not only ensures you get as much battery life out of your iPhone for as long as possible for those days when you really need it, but it also prevents performance issues caused by deeply degrading batteries.”
There are also software features that are designed to optimize battery charging. These include a feature where the iPhone will wait before charging 80% until it knows you’re ready to use the device again.
The YouTuber continued: “So, it won't sit at 100% for hours at a time. But if that does happen, you’ll actually receive a notification that says your iPhone should be removed from power and discharged to improve battery health.
“But deep discharges also negatively affect the battery, which is where low power mode comes in.
“At 20%, your iPhone will automatically begin throttling performance and background tasks to prevent the battery from draining.
“And while that means more battery life for the user, it also means a higher likelihood that the device will be connected to power before reaching an extremely low battery percentage.”
The expert recommends that it’s best to keep your battery level somewhere between 40 and 80% whenever possible.
