The best way to charge your smartphone – we’ve been doing it wrong for years
A company that offers devices that test smartphone and other batteries says charging your phone little and often is the best way
Smartphones? We are all accustomed to plugging our smartphones in to charge them up next to our beds before we go to sleep.
It helps make sure you wake up with a device ready to go and one which will last throughout the day, or until lunch-time at least depending on how many apps you are using.
But, apparently, this isn’t the right way to charge your phone and help its battery life prosper.
Cadax , a company that offers devices that test smartphone and other batteries, runs a free educational website called Battery University .
As spotted by BusinessInsider , it offers a host of tips for prolonging the life of your phone, reports the Mirror.
Don’t let your phone run out before you plug it in
We’re often told that you should fully deplete your battery before you charge it right back up again.
Again, this isn’t ideal.
According to the experts, a “deep-discharge” where you run it down to a fraction of its power is actually bad for batteries and will wear them out quicker.
So avoid the red warning if at all possible.
Charge your phone little and often
We’re all used to plugging in our mobiles for the long, overnight charge.
But it turns out that juicing up frequently and in small doses might actually be the best option for your battery’s health.
It doesn’t matter if you only charge up 10% or 20% as, according to Battery University: “Partial charges cause no harm.”
Keep your phone’s battery between 65% and 75%
It turns out there’s an optimal point to maintain your phone’s power – kind of like the optimal speed limit for burning gas and covering distance in a car.
According to the team at Battery University, the sweet spot is between 65% and 75% of your battery’s full charge.
Best keep that power pack handy.
Never fully charge your battery
This one might seem a bit counter-intuitive – but it appears that you should never charge your phone up to 100%.

That’s because modern lithium-ion batteries do “not need to be fully charged, nor is it desirable to do so.”
The website states: “In fact, it is better not to fully charge, because a high voltage stresses the battery”.
You don’t need to remove the charger when it’s full
If you do decide to ignore the point above, the good news is that you don’t have to remove the phone after you’ve hit 100%.
Battery University points out that the charger automatically turns off when it hits 100% so you’re not doing any extra damage by leaving it connected to your device.
That being said, if you’re not doing the battery any good by keeping it at 100%, it might be best to leave it alone overnight.
