CES 2018: Longer-lasting gadgets showcased

Spare a thought for the attendees of the CES tech show who decided to briefly leave their phones in charging towers.
The devices got locked inside when a power cut plunged the exhibition hall into darkness.
Having to constantly keep personal devices charged is a nuisance we are all, by now, familiar with – even device-makers are frustrated.
During Huawei’s press conference, the firm’s chief executive acknowledged that battery life was among the top complaints customers make about smartphones.
He went on to explain that this is why Huawei’s new Mate 10 Pro included a bigger battery than many rivals – at 4,000 milliamp-hour (mAh) capacity.
Seeing the world’s largest consumer electronics trade show briefly hobbled by a blackout perhaps makes gadgets with especially long battery life seem all the more appealing.
If so, a new flurry of devices at CES this year are offering to outlast their power-hungry brethren.
Take Lenovo’s Miix 630 tablet, a two-in-one that comes with a keyboard.
It is meant to last up to 20 hours on a single charge thanks to is power-efficient Qualcomm processor, a chip initially designed for mobile devices.
That claim from Lenovo hasn’t yet been tested, but it’s a tantalising promise of a more battery-confident future.
