I bought some knock off battery packs because who pays the full price for these OEM ones right? Well I was charging those knock off packs every two to three days (about an hour use per day), and after about a month they needed to be charged every day, not even two months in and they wouldn’t even stay charged for an hour so I caved and bought these stupid expensive OEM ones and holy hell, let me tell you. 20 days of battery life later the controller finally died and needed it first charge. These things last SO MUCH LONGER than those knock off packs it’s literally not even worth wasting your money on those things. Absolutely 100% spend the extra for these things.
The only downside I can say is that they lasted so long that I actually couldn’t find my charging cable in time and ended up dying in Minecraft cause I couldn’t pause the game lol. Still have no regrets though, these are worth every penny.
