You may be wondering why your EV's charging speed slows down when your battery is around 80% capacity. No, your battery is not broken. It's just your EV's way of maintaining health and longevity. Charging increases the temperature of EV batteries, and the higher the amps and voltage, the more heat is generated.
All the mobiles slow doens charging once it reaches 70-80%. It is normal behaviour to protect your battery. So don't worry.
To extend the lifespan of your battery, if the battery gets too warm, software might limit charging above 80 percent. Your iPhone will charge again when the temperature drops.
Lower your iPhone Temperature
To see if this is the problem, try lowering your iPhone's temperature by turning it off, removing it from the charger, taking it out of direct sunlight, and moving it to a cooler location.
So, the trick: Don't let your phone's battery drain completely to zero, and when charging it, only let it reach about 85 percent and then unplug. If you do fill your battery completely, don't leave the device plugged in; doing so constantly can cause your electronics to age faster in the long run.
The most basic one is charge whenever you want to, for a long as you want to. There's no reason to let the device drain completely before charging (in fact, it's a bad idea to do that on a regular basis), and there's no need to wait until it reaches 100% before removing it from the power source.
For optimized battery life, your phone should never go below 20 percent or never above 80 percent. It may put your mind at ease when your smartphone's battery reads 100 percent charge, but it's actually not ideal for the battery.
The batteries in iPhones aren't like old rechargeable. They don't develop a memory. Charge it whenever you like and to whatever capacity you like. The only thing that's "bad" for it is allowing it to discharge completely.
When the battery health is below 80%, battery replacement is recommended. Generally, this is about two years after you buy your iPhone, but it depends on your usage. There are many cases where 80% is reached after four years.
Charging overnight is not a danger to your battery in and of itself. However, temperature is a real concern. One of the most damaging things your battery can experience is extreme heat or extreme cold. Apple has publicly stated that temperatures above 35 degrees Celsius can cause permanent damage to battery life.
Like in lithium ion batteries it is said that it is good to keep your battery between 40 and 80 per cent so charge when you have 40 and then remove charging when it is 80.
To help extend battery life and performance, try to keep the battery level between 20% and 80% several times a week instead of using your device for only a short amount of time, and then plugging it in to recharge the battery.
Apple recommends, as do many others, that you try to keep an iPhone battery between 30 and 80 percent charged. Topping up to 100 percent isn't optimal, although it won't necessarily damage your battery, but letting it regularly run down to 0 percent can prematurely lead to a battery's demise.
What percentage should I charge the battery to? For regular use, we recommend keeping your car set within the 'Daily' range bracket, up to approximately 90%. Charging up to 100% is best saved for when you are preparing for a longer trip. You can adjust how full the battery charges from the charge settings menu.
Only Charge to 85% to Optimize Battery Life
As most lithium-ion batteries' capacity to hold maximum charge gets reduced after 500 charging cycles, Protect Battery may decrease the aging process and increase the battery's operational life span.
While fast charging can increase the rate at which your battery loses capacity, its actual impact is only about 0.1 percent more capacity lost than without using fast charging.
The 20-80% rule implies if you keep your phone's battery always between 20-80%, it will drastically increase your phone battery's life span.
This rule says that when charging your phone's battery, you should only charge it between 20% and 80%. In other words, you should never let your phone's battery go completely dead (below 20%) or completely full (over 80%).
The 40-80% rule is true. In truth, 20-80% would also work. The upper and lower extremes stress out the lithium ions.
If your battery health shows 81%, then it is soon time to change the battery. The battery needs to be replaced at the Apple Store or authorized Apple Service shop when the phone is down to 80% Battery Health / Maximum Capacity.
As a good practice, you should avoid charging your iPhone to 100% all the time and not let it go below 25%. Ideally, keep the battery percent somewhere between 30% and 80% to maintain your iPhone's battery health.
There are two reasons: charging performance and battery longevity. Most of the time you should only charge an EV to 80% because charging rates slow down dramatically past the 80% mark. And two, the long-term health of your vehicle's battery pack is improved when kept below 100%.
There is no danger in using your phone while it's charging. When you use your phone while charging, the battery is charging at a slower rate than normal to allow enough power for the ongoing usage.
How Often Should You Shut Off Your Phone? Experts recommend shutting down your phone at least once a week. After shutting it down, let it rest for a minute or two before starting it back up again. Not only will this help enhance your phone's performance, it is also incredibly beneficial for your battery.
