Samsung is about to launch a smartphone equipped with new graphene battery technology, fully charged in less than 30 minutes, by 2020 or possibly 2021 – that’s the information leaker Evan Blass posted on Twitter.
Today’s smartphones are equipped with a traditional lithium-ion battery, fully charged for about 1.5 hours. The fastest charging device to date is the Galaxy Note 10 with a 45W charging bulb, which according to Samsung can be fully charged in 1 hour only. In fact, that’s what Samsung claims, whether it’s true that they said it or not, because no one has tried it.
In his tweet, Blass said: ” Lithium-ion batteries have not reached the best level yet. Samsung is hoping to have at least one device released next year or 2021, equipped with graphene batteries. Full charge in less than half an hour, but they still need to find a way to increase the battery capacity and reduce the price “.

In 2017, Samsung announced that it is developing graphene battery technology: ” In theory … a graphene battery only needs 12 minutes to fully charge.”
This new technology consists of a layer of carbon atoms from the lead bar, called graphene, ” 100 times more efficient than copper in conducting electricity”. It also delivers ” 140 times faster ” energy than silicon used in current lithium technology, making it an ” ideal material for fast charging” – Samsung announced at the time.
We still do not know whether the graphene battery on a smartphone can help with longer battery life. To date, most smartphones need to be charged daily to ensure battery life can last for a whole day; a few smartphones can be used for up to 2 days.
