Apple's iPhone 12 launch event may still be some months away. However, according to a new leak on Twitter, it could be making a start on preparing for it by getting these phones and their components approved for sale. It may have progressed to a point where it is now certifiying batteries.
At least, the tipster @smartvenkat95 claims that Apple has submitted an "A2431" power-pack for testing by SafetyKorea. According to images associated with this alleged regulatory listing, it has a basic candybar form-factor rather than the L-shapes of previous years.
Furthermore, the leak apparently shows that the battery has a rated capacity of only 2775mAh. Apple will probably claim more in terms of typical capacity (presuming this new report is accurate, of course); nevertheless, it is considerably less compared to even the base-model iPhone 11. However, it is also in line with earlier leaks about its successor and its more expensive siblings.
