i drained it completely in january as someone recommended to do so. seemed like percentage was reading accurate for a short while, then wasn't again. recently went from 20 percent to 80 percent charge and the battery reading is still inaccurate.

for example i'll shut off the phone and turn it back on it'll either be at a higher or lower percentage, but always quickly drops off one of those percentages whether lower or higher.

not sure if this is the case with all phone types but did read they aren't always going to be super accurate, and really there is no real way to calibrate it and letting it deplete completely is a bad idea, your thoughts from your experience?
