Samsung revealed around 10 per cent of European Galaxy Note 7 owners have failed to return their devices some three months after the South Korean vendor originally recalled the unit.

The company is preparing to issue a software update on 15 December to halve the (already limited) maximum level of charge in the devices’ batteries in a bid to encourage the hold-out owners to respond to a device replacement programme Samsung initiated in September.

The latest software update will restrict battery capacity to 30 per cent of its original level and follows previous software updates limiting the maximum level of charge to 60 per cent, BBC News reported, citing a company statement.
