Which phones charge the fastest?

Everyone has experienced the moment of panic when out and about, when you look down and realise your phone is running low on battery. It's always a good idea to keep them charged, but sometimes you just don't have time to leave them plugged in for an hour.

Of course, it would help if you knew how long it took for your phone to charge up. Well, in this case there's an answer thanks to Tom's Guide, a tech website that has performed a test on some of the leading brands of smartphone to see how quickly each one charges.

The researchers plugged the phones in with the adaptors they come packaged with and charged them for 30 minutes, then for an hour. They then measured how full the batteries were after this allotted time.

However, they did make a slight change for the iPhones they tested. While most Android phones – including all the ones Tom's Guide tested – come with a fast-charging adaptor as standard, Apple's offerings do not. They therefore tested the devices both with their packaged chargers and with purchased equipment to allow them to fast-charge.

With the phones' packaged chargers, all three of the models of iPhone tested – the 8, 8 Plus and X – performed poorly. After 30 minutes, the iPhone 8's battery was at 30 per cent of its capacity, while it seemed to slow down slightly over an hour, only charging to 58 per cent.

The iPhone 8 Plus performed similarly, charging to 26 per cent after 30 minutes and 55 per cent after an hour. However, the new iPhone X was the worst-performing device. After 30 minutes it had only charged up to 17 per cent of its capacity, and after an hour it was still only at 37 per cent.

When the fast-charging adaptors – which cost an additional $68 (around £50.50) on top of the cost of the phone – were used, the iPhones were in the middle of the pack. The iPhone X was actually the best out of the three, charging to 50 per cent after half an hour and 81 per cent after 60 minuts.

However, the best-performing handset in this test was the OnePlus 5T. After 30 minutes of being plugged in with its packaged charger, the phone had reached 59 per cent capacity. Once an hour was up, the device was at 93 per cent.

In second place was the LG V30, which topped out at 86 per cent after an hour on charge. The worst-performing handset, when all phones were using fast-charge equipment, was the Samsung Galaxy Note 8, which charged up 74 per cent of its battery in an hour.

So that's how long it takes to charge the phones up, but what about longevity? There's not much point in charging a phone up if it is only going to run out of power after a few hours. Well, Tom's Guide also has data for that too, after conducting a test in which researchers surfed the internet continuously until the battery on each phone had run dry.

This time the top handset was the Google Pixel 2 XL, with an impressive 3,520 mAh battery that lasted for 12 hours and nine minutes. However, the Pixel didn't do well on the charging test, only getting to 75 per cent capacity after an hour of being plugged in.

The OnePlus 5T also performed well in this test, coming in fourth. It's 3,300 mAh battery lasted for 11 hours and 12 minutes when surfing the internet, making it a solid choice for anyone for whom battery life is important.

Interestingly, the LG V30 performed much worse in this test than it's quick charging would suggest. Despite having the same 3,300 mAh battery as the OnePlus 5T, LG's handset only lasted for six and a half hours when surfing the internet, which is considerably below the rest of the phones tested.
