Seems like it to me!
I have the extended battery & usually finish the day with close to 50% left. After rooting & installing SetCPU to govern the CPU while the screen is off & such to see if I could manage a full two days with one charge, I got the exactly opposite effect! I unplugged my Bionic at 6am yesterday, by 8pm my 15% warning went off & I wasn't even using it that much!
I also noticed my Quadrent & Antutu benchmark scores PLUMMETED with SetCPU, even set to performance mode! Antutu gave me a 4919 without & a 3430 with.
Glad I only paid a buck for it,
Anyone else getting similar results?
