The phone was turned off due to battery being empty, i plugged the wall charger to charge the phone while it was still turned off ,placed it in a cool place,i did not turn it on at all, after the battery was charged (green LED) i left it connected to the charger for a about 2 hours,

after that time when i picked it up it was really hot, dangerously hot!
the battery was hot and so was the left side of the phone,
i think i never left it charging while it was turned off before to notice this, now i'm doing all of those test (have a bit of free time) i'm noticing strange things

ok so common sense says the phone is off nothing is running, right?
the charging chip should stop charging the battery when it detects full charge (either by measuring temp or by the cell reaching 4.2V like any good lithium battery charger to prevent over charging the battery and reducing it's life or in some cases if the battery protection circuit fails the battery may catch on fire)

so why it is getting hot after it charged the battery, it should cool down, not keep getting hot!

i have KP51 installed for a while now and i'm noticing strange things
