Samsung has today revealed that more than one million customers around the world are now using a variant of the Galaxy Note 7 — either a replacement or a device initially sold in China — that sports a ‘safe’ battery .

This news comes almost a month after the firm initiated a global recall of 2.5 million Galaxy Note 7’s following its discovery that a faulty cell was to blame for some units catching fire while on charge .

It’s not all good news though. Some owners who recently received a replacement are reporting that their device is overheating and rapidly losing power as it’s charging.

The South Korean company is adamant that batteries aren’t the cause of the problem and has referred to the incidents as “isolated cases” linked to an issue with mass production.

However, a handful of customers in China, whose handsets pack the same cell as the replacements Samsung is distributing globally, recently reported that their Galaxy Note 7 had burst into flames.

“Currently, the brand new Note 7 products that have been swapped in overseas markets are using identical batteries to those that were supplied […] for the Chinese version,” writes Samsung in a statement on its website .

It then went on to share that it takes complaints of Galaxy Note 7 fires in the region very seriously and has conducted inspections on such handsets. It’s consistently found that batteries weren’t at fault for the incidents.

So there you have it, folks. Owners of replacement models elsewhere shouldn’t have to worry about it combusting. Although, if it’s feeling a little hot and is losing juice rapidly, best contact Samsung to exchange it.
