Chinese tech giant Huawei has unveiled two prototype removable lithium-ion batteries that can recharge in minutes, using a bespoke charger.
The lower capacity battery charged by 68% in two minutes – but is not big enough to run a smartphone for long.
The higher capacity one charged by 48% in five minutes and could provide up to 10 hours of talk time, the firm said.Current battery life is a significant limiting factor in the performance of portable devices.
Many tech firms and entrepreneurs are researching the issue.
In March, Samsung announced that the batteries in its new Galaxy S6 handsets could power up to four hours of usage after a 10-minute charge.
Israeli start-up Storedot unveiled a fast-charging device at the beginning of the year which it hopes will eventually be able to charge any smartphone battery in under one minute.
