Only aftermarket battery I would trust on the GS4 is the ZeroLemon 7200AH model. Tasker seems like an interesting software and I'll have to check it out, though. Have you played around with the KT kernel at all? Has some great adjustments directly at the kernel level, but for raw stability, I haven't found anything more rock solid than Adam 1.6. That paired with his Wanamlite ROM has made this phone look exactly like stock, but everything is buttery-smooth without a hint of lag, even when hard-scrolling.The cpu draw is significantly less than what I have it undervolted to. Also, it's pretty easy to hard reset the phone by jumping two pins on the inside of the phone. The Gs4 is typically pretty good for undervolting. I easily see an extra day just from my undervolting. I know the battery draw from it isn't nearly as much as the display or running applications, but anything to squeeze out more battery life is fine in my book. Also, I carry a warranty that actually covers rooting. Undervolting isn't the best option for battery increase and the gains may be marginal... but in my case, I saw a pretty significant increase. With my GS4, I'm easily getting 3 days with pretty heavy use, 4 with lighter use. I still own an original droid incredible that's been undervolted significantly for several years now, and still runs fine.
Tasker is my favorite app by far. I kill all running tasks when the phone is on screen off for a half hour or so. It also saves c-states so I can go back into what I was doing later on. I use it with my in dash tablet to turn on with the car, connect to wifi if my phone is within reach, and output audio through the digital connection, while opening my car dock.
Again with tasker, I can turn all 4 cores on or sync 2 cores together depending on the application in use. Say I'm running a really demanding program, I can set tasker to turn on all cores, and turn them off when the application closes.
Next is to see how long I can get with a double mah battery in the phone. Just not sure I'm ready to add bulk to the gs4 :/
Your username looks familiar...have you been posting in XDA on TheAxman's thread on using any carrier's ROM on the ATT GS4 or am I thinking of someone else?
