In theory, this can be done, and it can be activated when the phone is turned on.
But in fact, you shouldn't do it this way, even if you find a large capacity . Ordinary cell phone battery, it is thinner, larger in area and capacity. For larger ones, install them temporarily and then replace them after purchasing a soft package ternary lithium battery online.
There is no internal battery and part of the charge for charging the tablet is the tablet. When under low load, standby or shutdown, there is no battery and the CPU etc. operates at 5V under voltage. higher than that of lithium battery (the maximum voltage of lithium battery is 4.2V). It is easy to operate when overvoltage occurs and cause damage.
VIA 8650 tablet lithium battery output voltage and current
Three lithium batteriesum parallel and three series (2600 mAh 18650, probably Samsung 18650F, the battery has overcharge and overdischarge protection)
It is intended to be used for charging Cube MIX PLUS (tablet win10). The tablet supports 12V 2A or 9V 3A input, so it can be used.
