Just curious if you even check on battery life or just flash away.
Do you always flash plugged into power or do you flash untethered.
If you swap kernels do you worry about battery life the same as you do when swapping roms?
Obviously making changes at 100% charge is better than 40% charge. Is there a lower limit where you'll power up before making the attempt?
Also...ever been stuck in a boot loop due to low battery?
