I wish the Steam Controller used AA batteries
(lemmy.world)
Based on the description on their site, the controller includes a built-in battery: "8.39 Wh Li-ion battery, 35+ hours of gameplay... "
That was disappointing for me. Specially condidering the Steam Frame's controllers make use of AA batteries: "One replaceable AA battery per controller, 40hr battery life"
AA Batteries might not be as convenient to use, but being able to replace them is a great advantage. All my Xbox360 controllers still work fine, but none of my PS3' Dualshock 3s.
The official docking station could be used to recharge (rechargables) AA batteries so the functionality could remain the same.
Last time I ordered a phone battery from AliExpress I got it in two weeks flat. If you notice that your battery doesn't hold as long, just order a new one, it will arrive long before the device dies. There are also local battery shops, but they will charge a premium for quicker delivery.
Doing this once every few years is nothing compared to the hassle of taking out the batteries every time you want to charge them.
