December 2 news, foreign media Macromors reported that many Apple Watch users after updating watchOS 8.3, there is a problem of using third-party chargers to charge very slowly.
A netizen said:
Updated my watch to 8.3 last night, put it on my third-party charger this morning, came back an hour later and it probably only went up 2%.

There are also times when the Apple Watch will charge for a few minutes, and then the charging suddenly stops, restarting the Apple Watch can make it restart the fast charge, but this is not a permanent solution, charging problems will recur.
There are also a small number of users who report that they have also encountered charging problems when using the official charger, which should be the problem of watchOS 8.3. watchOS 8.3 brings the ECG function to the watch of the National Bank of China, which is still quite important, but for people in good health, this function is not particularly urgently needed. If the user has not upgraded watchOS 8.3, it is best not to upgrade it first. The scope of the charging problem is relatively large, and Apple should seize the time to solve it in the subsequent update.
In fact, after watchOS 8.1.1, there are a small number of users reported the problem of slow charging speed, but the scope of influence at that time was relatively small, did not cause a wide range of attention, XiaoLei's Apple Watch Series 7 is currently stuck in watchOS 8.2, with the official charger, did not find that there is a fast charging problem.
Some netizens said that the charger he bought Pinsheng found a problem in watchOS 8.2, contact customer service to send the charger back to upgrade, the current system is watchOS 8.3 Beta1 there is no problem, really feel troubled by the charging problem, and do not want to wait for the update of the small partner, you can consider using a similar method to solve.
Apple's recent system is indeed a bit crotch, iOS 15 has a lot of small problems, Xiao Lei before using, when entering from the lock screen, from time to time there will be a little stutter, to slow down for a while, or cut through the other interface and then come back, the application will respond. Apple also needs to strengthen the stability of the system to protect its advantage in software.
