Freaking battery on new ipad

What was the most surprising is the fact it won't charge while you use it.

Using the included charger with brightness set to 100% playing Infinty Blade 2 for an hour it went down 1%.

My understanding is this is lithium ion which is OK and actually preferable to keep topping it off when convenient of course.

The reason apple asks that you run it down once a month is not that it is good for the battery but rather a way to keep the battery calibration in sync with the logic.

Most top off, but my years of owning iPhones, iPods, iPads, I have always depleted them once a month and my batteries always seem to give me good performance. I think never running it down shortens long term life. There are several battery manufactures that agree.

Just did a little experiment, totally unscientific. Was surfing the web on my new iPad for an hour, using wifi, and plugged in to the provided wall charger, but using a third party cable (6' long). For the entire hour, my battery level stayed at 84%.

Went and dug out the provided cable and used it with the wall charger, and my battery cable has gone up 3% in 20 minutes. Doing the same stuff as before.

So for those of you lamenting the charge rate, are you using both the factory provided charger AND cable, the provided charger, or neither?

The one that came with your new iPad, or one from a previous product? It would be interesting if someone with electrical skills and knowledge could try measuring the resistance of the new vs. old cables.

New charger old cable kit.

They charge the same. I've tried various different combinations.

I have two of the new iPads to test they both perform the same.

It is just to much battery for a 10W charger to handle.
 
Well, since I switched 45 minutes ago, I'm up 7% (92% now), after seeing zero movement in an hour before. Same usage scenario.

And to be technical, I disagree it's too much battery for the charger. But the new iPad's improvements may draw more power than the charger can handle. If the battery was the same size as the iPad 2, it still wouldn't be charging.

I put mine on the charger around noon yesterday and at about 9:30 last night I was only up to about 70%. It was crazy. I wanted to get a full charge out of it before I started using it again so my ipad was out of commission yesterday. Hope it isn't always like this. Will suck if I can't get a full charge over night.

I was using a 3rd part 6 ft cable so now I'm starting to wonder if that had anything to do with it. Don't know why it would but will find out on next charge.
 
Not sure what the big deal is about charge time. I get at LEAST a whole day or two with mine on a full charge. When it's time to charge it, I plug the iPad charger into it overnight before I go to sleep. In the morning it's fully charged and ready to go. No inconvenience for me at all. I guess it is just the habit I got myself into.

Is that hard to believe? You had the brightness all the way up AND you were playing a graphically intense game. Ie, the two most power hungry components in the new iPad were getting worked to the max. What do you expect? Try surfing the web at 50% brightness and see what happens.
 
iPad Charging... TRASH

Plugged in my iPad last night at 10:30 with 29% left. Woke up this morning at 5:30am and it was charged to 85%!

I was using the charger that came with the iPad and apple extension cable!

56% in 7 hours? 8% per hour?

ON the other hand I just charged my iPad 2 from 17% to 80% in 4 hours.

15.75% per hour...

Neither iPad was in use during each charge!

Also while charging, with brightness at 100%, just browsing the web using LTE is was actually losing battery... it was a slow drain, but still.

I suppose that yes if you don't push the iPad to hard it will charge. But the fact that you can't use it in a normal fashion and get it to charge off of the wall plugin at the same time is not a good sign.

Even just surfing the web with the screen turned down a few notches it only charges a few percentage points per hour.

I don't think Apple was stupid about this. I wouldn't be surprised to hear they tested 20W and 30W chargers and found the heat to be unacceptable. This is a problem that will have to be solved in the years to come. More battery requires more charge time.
 
Same thing as the poster above said.. I seem to lose 1% every 5 min or so even when I'm just browsing twitter or reading the news. Is that normal?
 
I've had great battery; drained it to zero over two days, plugged it in over night with the new charger/cable, and 6h later, 100%. Wifi + 4G, though I don't have a SIM installed yet. And I've noticed that on my MBP (2010) it reads as charging when syncing, which from the forums (haven't owned an iPad before) I didn't expect it to.

Been using it hard since friday and still at 19%.

just old habit, like to drain before first charge.

Loving my ipad.

You're smart to do that. It's good to drain it a couple of times to break it in. I topped mine off when I unboxed it on Friday and have been using it all weekend--it's still in the 30s even after my marathon session with it yesterday.

:eek:Apple should have made a 35 watt charger for this thing. I knew it would be bad, but not this bad.

The problem is the dock connector and USB voltages. I seriously doubt those tiny little pins could handle the 7 amps of current required at 5 volts to charge at 35 watts. If apple boosted the voltage to the old 12 volt FireWire powered iPods you can cut the current required down to about 3 amps which might be doable.
 
Ran my iPad till it died, started with ZERO on Battery Meter and it took exactly 6 full hours to totally charge back to 100% and quit charging.

I can live with that. I think folks are making way too much out of this. WAY TOO MUCH!
 
Just an update... Battery was at 72% this morning and it's now at 58%. . I've haven't done much other than browse some web pages, check twitter a few times and read for an hour or so on the kindle app

14% would be 1 hour 24 minutes for a 10 hour battery. Sounds close.

Kindle app drains our iPad 2 and 3 very quickly (oddly enough).
