I own a Samsung Galaxy Z Fold 6 paired with a Galaxy Watch 8, and Iโve been dealing with multiple serious issues since updating to One UI 8.0 in January 2026. The problems still havenโt been fixed, even after several security updates and the 8.5 software update.
Battery drain
Both the Galaxy Z Fold 6 and Galaxy Watch 8 now drain much faster than before, even with light to moderate use. The devices no longer last nearly as long on a single charge as they did prior to One UI 8.0.
Bluetooth issues
Bluetooth is extremely unstable across multiple devices, including my Galaxy Watch 8, Bose headphones, both of my vehicles, and several other Samsung and nonโSamsung accessories.
The phone and watch frequently connect and then drop the connection seconds later.
I can't speak to your z-fold, but many people are having issues with the faster battery drain on the watch. This, I think, was due to an Android play services update that happened recently. It seems to send Google Play services into overdrive and is draining the battery at a phenomenal rate. Check your battery usage statistics on the watch and see if Google Play Services is at the top of the list. It should be noted, that some of us are also having issues with the watch saying "no battery usage" even though the watch has been in use several hours. I believe the two issues are related, as when my battery statistics do reappear, GPS is at the top of the list and the battery drain is quick. Conversely, when the battery stats disappear, the watch goes back to normal usage. I think that somehow GPS controls the battery use statistics, which is why the drain is enormous when they show, and normal when they don't. Given that in the past GPS barely registered in the battery usage, I'm thinking this is a Google issue, even though I have reported it as an error to Samsung. I think that I will report it to Google, as well.
