Nothing interrupts a good gaming session quite like having your controller run out of juice. When you get that low-battery warning, do you get up and look for your second controller (assuming it has any charge) or do you stick it out and hope you can finish your mission/level/whatever before the controller dies? Even if you have a second charged controller sitting right there, you still have go through the annoying process of switching to it. Yes, I know, I know, First World problems, but still…it’s a pain in the butt. Well, it seems the PS5 may solve this little irritation.

Sony has patented a new “low battery switch over” system (thanks to Respawn First for the find), which will likely be a feature of the PS5’s new DualSense controller. Basically, when you get that dreaded low battery warning, you’ll be given the option to immediately and seamlessly switch over to a second controller. You can check out a diagram of the system, below.
