Customers using the Xbox One S have really been going through issues with performance. Most of the issues appeared when the devices used the instant-on feature, with the console reportedly stalling when it was loading store pages, dashboards, game lists and so on.
To help, switch the energy saver mode on. However, not even this was a permanent solution, since it didn’t work all the time and for everybody. Now, the next build for the Xbox One S will supposedly remedy this problem. The Reddit user who posted this information claims he knows that because he’s been exchanging emails with someone who works in the company, namely the Senior Software Engineer in Microsoft.
Even though this is not an officially confirmed information, in the past this user has given away other pieces of information that turned out to be true.
Other fans on the forum complained that they requested some help from Xbox Support but did not receive any useful answer. This was quite a source of dissatisfaction among gamers. Others complained about upgrading and still encountering the issue.
