Samsung Could Have A Smartphone With A Graphene Battery By 2021

Smartphone batteries aren't something that we think a lot about beyond the capacity, since that usually gives you an indication of how long the smartphone will last on a full charge. Most smartphones today have lithium-ion batteries, which while capable, are now falling short on capabilities as smartphones are getting more powerful. The solution could be in the smartphone industry adopting graphene batteries, which could be coming to at least one Samsung smartphone by 2021, according to tipster Evan Blass (aka @evleaks).

Graphene batteries on smartphones using Samsung's graphene ball technology have been tipped for some time now, but a new tweet by Evan Blass suggests that it's still some time away. Blass' source suggests that Samsung hopes to have at least one smartphone with a graphene battery by 2021. For the time being, capacities still need to be raised while simultaneously lowering costs, according to the tweet.
