Samsung’s latest software update for the Galaxy S8 and Galaxy S8+ may have broken fast charging. Some users are reporting that the feature simply does not work after installing the October security patch — not even if you use an official Samsung charger.
Samsung’s Galaxy S8 and Galaxy S8 Plus, specifically the Qualcomm Snapdragon 835 versions deployed in the United States, seem to be having problems with charging after a recent update.
The update in question seems to be the October security patch, and many users are reporting that the update has caused their Galaxy S8 and Galaxy S8 Plus units to either no longer fast-charge, or no longer charge via the USB Type-C port at all.
Some users reporting the latter are also saying that their phones are charging slowly when charged wirelessly. Wireless charging is usually a bit slower even than charging with a generic cord and adapter, and no users seem to be reporting such an issue with Samsung’s fast wireless chargers.
Additionally, some users are reporting fast battery drain following the installation of the new software package. Samsung has yet to make any official comments on the matter.
It’s worth noting in this case that no other Samsung phones seem to be having the same issue. The Galaxy Note 8, which is based on the same chipset, has been reported having some charging issues, but they don’t seem to be connected to the October update.
The international versions of all three phones based on Samsung’s own Exynos chipset rather than the Snapdragon 835 also seem largely unaffected. Since it’s almost December, the November patch should be coming soon and should hopefully help with this issue.
