I am having a very slow charge too. Before, I charged my N7 for 3 hours-ish. Never had any problem since I bought it on August last year. But these days, it takes 10-12 hours or even more to reach 100%.

But then, I notice a pattern that lead to that problem. Since I returned from USA, my niece always play my N7. And she always play it until it totally run out of juice. Every time she handed me my N7 it will be zero % (you know when you boot up your N7 it shows the red exclamation mark on battery)

The weird thing is, it takes forever to charge. Like maybe 8% per hour charging.

Today I think I have solved the problem. I followed this theory. I don't know if it's true or not. It seems like the battery needs a certain type of program to charge. I have no idea what is the name of the program. Since my N7 is dead, it seems like the program is not running at early time of charging, hence very slow charging time. And N7 failed to start the program even if the battery level has reached a decent level, maybe above 14%. So, in order to curb that problem, I think soft reset might help to restart that program. Here are the steps.

1) I charge my dead N7 using the charger, not USB (I haven't tried using USB), but i think using USB is much slower.

2)wait for maybe 10 minutes, so you get maybe 1% or 2% of battery life

3)Soft reset N7, I hold all three buttons for maybe 10 seconds (power, volume up and down button), then it will enter the bootloader mood. Wait 3-5 seconds and then scroll to 'power off' option. Select option using power button. N7 will then shut down

4)Unplug charger. Now wait for a couple of minutes before proceeding to next step. I wait 3-5 minutes.

5)Start N7. Wait until enter homescreen. Then quickly plug charger back.

I did that and I manage to get increment of 1% in every 3 minutes. So, basically it will take 300 minutes (5 hours) to charge to 100%.

Next time I'm gonna plug my charger once the battery dropped to 14%, never let battery totally run out of juice anymore.

p/s Still cannot get 3 hours like before but better than waiting for 12 hours

Also, I heard with the latest jelly bean, it should take 5 hours. Anyone can confirm that?

My pleasure. Good luck!

Hey guys, anyone know any lowyat seller that sell Asus OEM charging cable? The one that comes with the nexus 7 set? Mine is broken months ago. Since then I have been using normal USB cable. That might explain why my charge rate is slower than before. I still have the adapter, just the cable is broken. I've been looking for quite some time in lowyat. Appreciate your help!

Thanks for the info WIS9000. That way, I think I better use a regular cable.

Btw, may I know how long it takes for your nexus 7 to fully charge? Mine take around 5 hours. I am wondering if my battery is in a bad condition already.

If in the case the battery has gone bad, do you think I can have a replacement from ASUS SC? Since it is still under warranty. I have never done this before, so I don't know if SC will consider replacing a case like bad battery. Because by nature, a battery will get worse over the year. Anyone?

Thanks for the info! I shall request from SC tomorrow
