Today I purposely used the phone at 8am to drain a little. Plugged back in at 9am to "top up" and took off charger 30 mins later.

I did not notice the initial "reported" drain. Note this is completely unrelated to the original "huge drain" issue which happened in the middle of the day.
Not really. I charged it again to full and when it say battery is full, then i disconnected it again to test it out and happening like what i describe above. You have to run the commandline to see how much the battery is available.

Even if you recharging it until it fill up again, it would end up draining again. The drainage didn't stop there though, it continue until it reached 50% mark. This is not normal. The more power it has is the more it will use. At 30% i left my phone connected on wifi for 2hours and yet battery still say 30%. This is what it should be like from the full charge.
