A couple of days ago, Huawei's official France handle tweeted about the unreleased Huawei P40. The tweet explicitly claimed that Huawei's next flagship, the P40, will come with a next-generation graphene battery. Along with the tweet was a fan-made concept render. Unfortunately, the whole thing is full of red flags, so we will continue the rest of the story with a high level of skepticism.
Following the tweet, a well-known smartphone leaker @IceUniverse negated Huawei's tweet, replying that "this is a technology this is currently impossible. Remember those red flags we mentioned a second ago? Those are:
1.) Huawei tweeting about a device that hasn't been announced yet2.) Huawei's inclusion of graphene, a technology that currently isn't used on other smartphones, 3.) The images of the P40 from the Tweet were actually fan-made concept renders4.) Huawei France has since taken down the Tweet.
It seems like someone part of Huawei France's Twitter account must have based this tweet off the wrong information, which Phone Arena suggests is from an earlier tweet about claims of a 5,000 mAh battery that charges in 45 minutes.
Back in August, Samsung was reported to be working on next-generation battery technology using graphene that would replace Lithium Ion batteries used in all smartphones today. Such a device wouldn't even be unveiled until later next year or 2021.
Wild assumptions aside, the Huawei P40 Pro is expected to arrive early next year with an impressive 10X optical zoom periscope camera setup with a reported f/4.0 aperture. Huawei's P-series smartphones are always co-branded with Leica and heavily focused on photography capabilities.
We're also expecting to see a 6.57-inch curved FHD+ AMOLED display and two front-facing cameras through a hole-punch camera in the front. We are also expecting the P40 Pro to run the Kirin 990 CPU and won't come installed with Google Mobile Services as of the writing of this post. Huawei has also been raising its efforts to create an alternative ecosystem for its foreseeable Google-free future.
