A few days ago, we saw a rather unexpected leak that said one of the most exciting Android handsets of 2020 will feature the biggest smartphone innovation in years. Out of nowhere, Huawei France posted on Twitter content that said the P40 series will come with a graphene battery inside, which would not only be smaller than regular lithium-ion batteries, but it’d also pack bigger charge and support faster wireless speeds. Huawei deleted those tweets, but not before someone saved it. We’ve been expecting smartphone makers to adopt graphene batteries for years, with Samsung being one of the rumored candidates for the change. It turns out the technology isn’t ready for 2020, after all.
