Why Charging Your Phone To 100% Could Be Harming Its Battery Life
However, an expert has discovered that charging your phone to 100% may be damaging it. If you do this, you are likely in the majority of people who enjoy doing this.
Nothing is more alarming than noticing that your phone simply won’t have enough battery to finish the day.
As everyone else would, you fully charge it so that you know you have more than enough battery to last you through whatever the day brings.
To avoid the inconvenience of being without your valuable phone throughout the day, you might even choose to charge it overnight.
But in the long run, you can be harming both your battery and yourself.
You may already be aware that charging your phone to 100% capacity can have negative long-term effects, but it has long been disputed whether this is true or a rumour.
Fortunately, an expert has provided insight, allowing us to finally put this matter to rest and take appropriate action to avoid the hassle of having to upgrade our phones or get a new battery.
There is some validity to the full-battery charging rumour, according to Chao-Yang Wang, head of Penn State University’s Electrochemical Engine Centre.
According to the Huffington Post, he revealed that “a battery will degrade faster if you charge it to 100% versus a little bit lower state of charge.”
Additionally, if you keep charging your phone to 100%, it will be at a high voltage, which will cause it to age chemically, according to Dibakar Datta, an associate professor of mechanical and industrial engineering at the New Jersey Institute of Technology.
Wang went on to say that if you keep charging your phone fully, you could be losing 10 to 15 per cent of your battery faster over its lifetime, than if you were to charge it to 90 percent, adding: “So it’s not a whole lot, but it’s noticeable.”
So, while the deterioration might not be as noticeable at first, Wang says that phone batteries are largely durable, as he continued: “[Batteries] last, probably, longer than the other features of the phone. You likely will need a new phone for other reasons, such as camera quality or a broken screen, before you need one for battery issues.”
This shouldn’t stop you from charging to 100%, though, at least occasionally.
According to Wang, it’s a case-by-case situation, as it all ‘depends on people’s needs and also convenience’, as he added: “If you do have a mission-critical day, you will be better off to charge to 100% so you have more electricity and longer usage time.”
However, 85 to 90 percent should be adequate to charge your phone if you are just relaxing at home.
It’s not a good idea to allow your phone run out of battery in addition to not charging it completely. I sigh.
This is because it can impair the battery’s capacity to retain charge, causing it to discharge more quickly.
To prevent this, Datta advised charging it at a rate of about 20%. He also advised avoiding extremely high or low temperatures to prevent your phone from wearing out.
Fast-charging ports should also be removed, he said the publication, because they cause heat to build up inside the battery, which over time might deteriorate it.
“I think that the battery is probably more afraid of too cold or too hot [temperatures].” Wang added. “I think that damage under those extreme conditions probably is greater than charging to 100% under normal temperatures.”
