HSPA is draining your phone. Seriously. Whatever I do when I use mobile data on HSPA, battery drops like a rock.

It's supposed to do that.
It doesn't charge up to 100% to preserve the battery's health, it's designed this way.
If you really want it up to 100%, you can always bump charge it.

Also to note. Bump charging can cause problems, so read that to decide whether or not you want to do it.
Oh ok thanks..so just leave it at is? It bugs me but I can live with it lol

I hope so, my note 2 arrived this morning and so far all I can say is WOW, it is awesome. The biggest problem with smartphones lately is their battery life so lets hope this is different!

Same here, I have challenged the battery on this phone to no end. I had a 15 hour and 22 minute "on charge" day yesterday with 4hours 44minutes screen on and the SOB was at 30% when I went to bed. The battery on this phone is unbelievable. I am using it stock, CF rooted, with nova.
Here is the photographic evidence in note style:

The WiFi has been on all the time. As I said though, I've not been using it for much apart from texting and a bit of light browsing.

you shouldn't have a problem downloading a 1 or 2gig movie within 30 minutes to an hr, it'll drain your battery half way regardless of kernel though.
If you're worried, you should stop pirating or Johnny Law will be on your rear. jkjk
To answer your question, just use it without connecting to the charger. Also, calibrating the battery is not necessary either.

So draining the battery regularly doesn't hurt it?
So in conclusion connecting the charger hurts the battery?

Keeping your battery at 100% all the time (letting your phone plugged into the charger) is literally the worst thing you could possibly do to the battery besides overheating it.
If you want to get the longest lifespan out of the battery, keep it between 40 and 80% and under 40°C (which is why the N4 starts throttling itself at 38°C)

Of course it will. It's a battery. They only have so many charge cycles. You can always buy another. With a little effort the battery can be swapped out.
That's right anyway I just wanted to know the least way I can damage the battery while downloading. ..do u have a suggestion

I can't give you advice on how to make piracy less damaging to your phone. That's against the rules.

I just had my lawyer answer a ~1800 euro claim for some song that had magically found its way into my torrent downloading software. He charged me 208€.
Don't download pirated media..
He never said he was downloading copyrighted material... plenty of legal Ubuntu torrents available and last time I checked that's not piracy

So in conclusion
I should download until the battery drops to 40% and then recharge it
