iPhone users warned against leaving your device on charge overnight

iPhone users warned against leaving your device on charge overnight

As tempting as it might be, iPhone users have been warned against leaving their devices on charge overnight.

Most of us are guilty of it – heck, some of you might be plugging yours in right now, setting those hundreds of alarms ready for the morning grind.

But doing this could actually be causing damage to your iPhone's battery life, with tech experts telling users to avoid leaving it on charge for hours at a time if they want their device to last.

And now tech TikToker Shomes has made a video on the subject, providing anecdotal evidence as to just how damaging this practice can be.

"Everybody loves to say how trickle charging is a myth and charging your phone overnight has no impact on your battery health, but I'm going to prove it to you right now," he says.

Holding up his iPhone 13 Pro Max that he bought at launch last year, Shomes turns it around to show that it's at 100 percent battery health.

He then compares it to his wife's regular iPhone 13 that was bought three months after launch, which is currently at 93 percent.

Finally, the TikToker whips out a bonus iPhone 12 Pro that he bought a year before the 13 Pro Max – and it's still at 100 percent.

Shomes continues: "She puts her phone on the charger every single night before she goes to bed and I can count on two fingers how many times I've done that.

"So if you care about your battery health, whether it's for resale or getting maximum battery life on a day to day basis, then you need to stop charging your iPhone overnight."

The reason that it does damage is that our batteries are a bit like us – they too can get stressed when overworked.

So when your phone has reached 100 percent charge, it gets what's called trickle charges to maintain it at this percentage while plugged in.

According to Battery University, this keeps it in a high-stress state which wears it down from within over time.

That being said, some experts have spoken out in the past to suggest otherwise, including tech author Jesse Hollington.

Taking to a Quora thread on the matter, he wrote: "Charging your iPhone overnight will not harm your battery in the slightest.

"Charging your iPhone from 90% will not harm your battery either. You simply can't overcharge an iPhone, or any other modern electronic device, for that matter."

Still, if Shomes' evidence is anything to go by, perhaps take the extra precaution and try to charge at intervals throughout the week rather than all night long.
