I've had my N2 for a few weeks now. Suddenly, it has taken much, much longer to charge the phone. I calibrated the battery, drained it to 0 and plugged it in. 3 hours later it's still at 50% (and the phone is charging while off. Any suggestions?

Are you using the stock wall charger and cable that came in the box?

Re: [Q] Battery Taking Too Long to Charge
The reason the battery is taking so long to charge is because you ran it down to 0. If you want your batter to last longer it's best to use the 80 / 20. What I'm saying is use the phone down to 20% and recharge back to 100%.

May be a faulty battery. Contact Samsung (I'm assuming that by n2 you mean note 2) and they'll probably send you a new battery.

I only had one issue, yesterday, and it was that my phone showed 25 percent charge on stock white Samsung charger/cable and I knew it had been on the charger longer than that. I rebooted and it showed 74%. Not sure what the hell this was about.

Re: [Q] Battery Taking Too Long to Charge
Old rules by what standard? Anytime using lithium type of battry is best not to run it down to 0%. I guess you don't have much experence with them besides your phone. I use them everday for my hobby. Sure you can run them down to 0% if you like replacing them quicker.

More than likely slow charges are due to a slow charge plug/cable...many prior posts on the charger.

Old rules were for NiCad tyoe batteries, where you did want to run them down to 100% and had to deal with other issues. If you do end up doing that Google search you will find the advice given is pretty accurate. Staying out of the high and low ends for long periods will give you many more cycles.

Re: [Q] Battery Taking Too Long to Charge
I know this would be obvious, but I figured I will ask anyway. Are you still running the stock kernel, or are you possibly running one without the capability to accept the 2.1A charging?
