Smartphones that run out of juice in just 90 minutes

SOME modern smartphones will die after just

0 minutes of browsing the web, the consumer group Which? has revealed.

It made the revelation while putting together a guide to the handsets, tablets, laptops, Bluetooth speakers and wireless headphones that offer the best and worst battery life.

And the organisation’s stringent tests have shown that, while Apple and Samsung dominate sales, they have some serious rivals when it comes to battery longevity.

It was the HTC 10, which costs £470, that came out on top, according to Which?. It said: ‘Our lab tests found that it will take a mighty 1,85 minutes of continuous talk time before its battery finally runs out of juice – that’s a minute shy of 31 hours.’

By contrast, it found the budget Rook smartphone from EE, which admittedly costs just £40, had a browsing time of just 0 minutes before it went dark. Talk time was an equally miserly seven hours. Which? said: ‘OK, so it won’t spontaneously explode in your face, but the EE Rook’s dreadful battery life is the very worst on test.’

Meanwhile, in the tablet category, the Samsung Galaxy Tab A .7 was the best, with 16 hours of battery life, beating Apple’s iPads.

The group’s revelation comes amid concerns that advances in battery power have failed to keep pace with the increasingly sophisticated technology in phones, tablets and other gadgets.

All the apps, cameras, video streaming, web browsing and GPS mapping services available with modern smartphones puts an enormous strain on the batteries.

The recent Samsung fiasco involving its ‘exploding’ Galaxy Note7 smartphones was the direct result of a systematic battery failure.

A Which? spokesman said: ‘The estimated figure of how much the recalled Samsung Galaxy Note7 mobile will cost the manufacturer varies wildly from $2billion to as much as $18billion. What we do know is that it’s all down to that key component of any smartphone – the battery.’
