Today scooby609 reports that he nearly doubled the charge life of his DualShock 4 (DS4) PS4 controller simply by replacing the battery pack with an http://www.amazon.com/gp/product/B00964CPAO/ DualShock 3 (DS3) battery pack.
Below are the details, to quote: The battery in the DS4 is a 3.65V 1000mAh battery.
The aftermarket DS3 batteries fit perfectly in the DS4 with no modding required!
One I got is a 3.7v 1800mAh battery (the mAh rating is the charge life rating) it cost me under $9 shipped!
I have gone from around 8hrs per charge to nearly 14hrs per charge with the new battery!
