Does anybody experience the same ??? This just isn't possible ??? From the 5 hours it usually went ???

I play with my controller plugged in mostly so i don't have a problem with it. I hear a company is coming out with a replacement battery that has a longer battery life.

Li-Ion batteries do die. Maybe yours was bad to begin with. Nyko has a replacement coming or may be out now. I would think Nintendo would jump on the opportunity to sell extended or replacement batteries.

It shouldnt be reasonably expected and you have a 1 year Warranty.

Don't buy a new battery

Given how limited the range is, why not just play with it plugged in?

Don't buy the Nyko one. If that battery messes up your Gamepad, you're out of luck when it comes to the warranty.
Just tell Nintendo to send you a replacement.
Tell them your battery lasts way shorter than it did when you got it, but the Gamepad is working correctly overall. They may send you a battery for free, then ask you to send your old one in, and will charge your credit card if you don't send the old one back.

Either your battery is messed up or you've been geeking waayyy too hard. If you can prove it's that bad, Nintendo should settle it with you with your warranty. (As a rule, ALWAYS consider informing Nintendo first.)

It never happened to me and I never had to play with the cable hooked on. As for the range, I've been playing at the edge of the living room, in the bathroom... even in my room.

Sounds like a bad battery. Mine is still doing just fine and the range is incredible. Quite frankly, I'm surprised at how far I can take that thing and still game on it.

Nyko battery to the rescue!

My bedroom is directly above my living room where the Wii U is. I can play at night but at that range I've found my battery life is shorter. "Gaming" @DePapier as I like to call it I have been doing waayyy hard, but not too lol. I feel sorry for anyone sleeping on this system,though the awakening will begin in less than two weeks.

Mine is very fine.

i think you should take it to where you bought it from and ask for a replacement.

He can't do that. They would have to open a Wii U up and take only the gamepad.
Best bet is calling Nintendo and asking to send him a free replacement, then send the faulty one back.
In the worst case, they ask to send in the whole gamepad, but I doubt they'll do that just for a battery.

CALL NINTENDO.

And people like you are why I dont miss working in retail

Yes, really. As if you aren't near an outlet 100% of the time you're pplaying the Wii U.

I am! With my GamePad sharing the same power supply with the Wii U itself, I never have to worry about unplugging that power hungry controller!

And they're gonna say no

I always have the brightness turned down to the lowest setting on the gamepad when I play. If I play just using the gamepad I'll turn up the brightness, but my battery life seems fine when I do that.

Does Playing witht he Wii U GamePad constantly plugged in kill the batterys life span?

YES, i second this. Try working in retail before thinking; oh just send it back to the store theyll take care of it all.
