Huawei is likely to upgrade its P40 smartphone by adopting graphene technology to expand its battery capacity to upward of 5,000 mAh, so that it can better accommodate the power-guzzling demand of the 5G network, an industry insider told the Global Times on Thursday.

The Chinese tech giant is expected to launch its P40, successor of the Huawei P30, in the first quarter of next year, according to media reports. The new device will be equipped with the Kirin 990 5G chipset. 

As battery capacity is one of the key indexes that determine the performance of a 5G smartphone, some bet Huawei -facing a US trade ban that could potentially cut off its supply of US parts and weigh on its overseas sales – may introduce graphene technology to increase the competiveness of its new devices and appeal to more 5G users. 

Huawei’s P30 series is powered by lithium batteries.

Currently, the maximum battery capacity of most smartphones in the market is about 4,000 mAh. US tech firm Apple’s iPhone Pro Max has a battery capacity of 3,969 mAh – the biggest battery Apple has ever used in its smartphones.

“A graphene battery above 5,000 mAh will give Huawei an edge in the increasingly fierce 5G competition, in particular helping it to outstrip foreign rivals,” Xiang Ligang, an expert on the telecommunications industry, told the Global Times on Thursday. 

The widely expected graphene battery, coupled with Huawei’s newly developed 50W rapid-charging technology, could take only 45 minutes to charge fully, industry website gizmochina.com reported. 

Huawei has seen brisk sales in the third quarter of 2019. It shipped 41.5 million units in China from July to September, up 66 percent year-on-year, according to a report from Canalys.
