Root What is SBC?

[toomuchgame441]

Since the new GB source code for our EVO came out I've heard talks of SBC, what does it do exactly?

SBC = Superior Battery Charging

Check out the Dev's thread here, he explains what it is and what it does. Hope this helps.

also here is a great discussion on sbc kernels:http://androidforums.com/evo-4g-all-things-root/319636-sbc-no-sbc-kernel.html. post #18 by novox77 really explains what is going on with sbc kernels. good stuff.

Only the greatest thing to come to battery life since the wall outlet

LoL I really miss having an sbc option since flashing this breed ROM. I like the ROM, that's for sure, but I hate the dreaded 10% battery drop right off the charger

SBC=Superior Battery Charging

Possible issues here with the SBC charging. I would sway away from these style kernels ( BATTERY EMITTING "SMOKE" (Trickle-Charge Kernel most likely responsible?!) **PICTURE* - xda-developers )

SBC is a type of "trickle" charging. It's a full, slow, complete charge and it prevents the 10% drop that most users get when pulling the phone off the charger. This kernel performs best with an overnight charge. Some users asked questions on the safety of the SBC charging method. Ms79723 states that it slowly pushes mV into the battery and thus keeps the battery cool. SBC kernels push the battery past their normal 100% charged point, to a TRUE 100% charged battery. These kernels also charge extended batteries to their maximum and show true "on charger" voltages, which would deem these to be more accurate for checking voltages on your battery. There was and still are concerns of the SBC kernels destroying your battery, but to most people now these don't pose much concern anymore.

The issues people were bring up is that the Li-Ion batteries are charged to the point HTC set them to was for safety of the battery. Li-Ion's can be unstable at times, but Ms79723 programmed safety temperature and voltage "stops" to kill the charging is they get too high. Bad things can start to form, I said can not will, if the temperature gets above 140f and voltage gets to or past 4230mV. If the mV gets to 4230mV it can causes issues. If it gets to 4300 mV it can cause plating. People are also speculating that the SBC kernels are going to kill your battery and or shorten the life. With the price of eBay batteries now days, if the SBC kernels give you drastically ( which has been seen ) more battery life, then why not? The highest seem on the SBC kernels is 4210mV, which is under both values for issues to start.

that was taken from the kernel guide from xda. here is the link of you want to read more on kernels:[GUIDE]
