Will you wreck your mobile, charging it overnight?

21 September 2015

mobile Most people charge their mobiles overnight, because you can get it revved up and ready to go while you're asleep, which is the only time you're not using it. However, some people have said that overcharging your phone is bad for it.

Is that true?

Well, according to one tech writer, it isn't. In fact, overcharging any modern device won't affect them in the slightest.

Answering a question on Quora, tech writer Jesse Hollington said: "You simply can't overcharge an iPhone, or any other modern electronic device, for that matter. When your iPhone is plugged in and reaches 100%, it switches to external power and simply runs from that."

Basically, his explanation shows that any device that uses a Lithium Ion or Lithium Polymer battery has to incorporate a charging circuit that cuts off charging power when it reaches 100%.

Hollington added that, if you charge your battery before it is fully depleted, that is actually the preferable way of doing things, regardless of what the bloke down the pub told you. This is something to do with 'charge cycles'. He said: "Every time you charge your iPhone up from 90%, you're using 10% of a complete charge cycle. This means you could charge your iPhone up from 90%-100% 5,000 times before you'd have to worry about running out of charge cycles."

"However, if you deliberately drain your battery to zero and then recharge it, you're needlessly using up a complete charge cycle. Obviously if you're using your iPhone until the battery goes dead, that's fair, but there's no need to deliberately drain it before recharging it, and you'll actually shorten your battery life if you do so."

That's if you can even use your iPhone. That said, if you have been stung by the iOS 9 update, here's some things to try out before throwing your phone out of the window.

    Shallow charges are wank for the battery. Nuff said.

    Who cares? Just buy another equally shit battery off eBay for £3. Job jobbed!

    I wouldn't trust a "tech writer" to know either way when it comes to batteries and the like. They don't generally have much long term experience because well, they're not going to use the same device every day for three years are they? They're going to have shiny new ones coming out of their ears. And really devices are designed to be replaced so I doubt the manufacturers care much for long term either. What's the point when people have stopped talking about it?
