3G Jailbroken iPad vs Wifi Non-Jailbroken iPad: Battery Test In Progress

HXGuy said:
That's true, it's not going to be the end all of battery tests, but Im curious to see what happens today with the 3G Data turned off. If its exactly the same as yesterday, then we know its 100% the jailbreak causing the battery consumption, right? And if they are identical to each other in battery use today, then we would know that the jailbreak has no effect on battery life.

If its something in between...well then...I guess we won't know exactly what is causing what, but we can assume. :)

No, even if it would be the same with 3G off you could not claim it was the jailbreaking that caused the difference in the first test.

Ok but so far it looks to be working out that they are the same with 3G off...so it appears that it was all 3G radio that was causing the battery drain and 0 drain from the jailbreaking. This was after 1 hour of use...we'll see in 50 minutes what the 3 hour result is.

One wouldn't expect jailbreaking to have much of an effect unless you use the jailbreak to install multitasking apps and to run them in the background.
 
Well this is weird...

After 5 hours, the two iPads are 1% apart in battery life, which is good, but they results are not the same as yesterday, mainly for the Wifi model. Strange, no?

After 5 hours yesterday, the Wifi model had 72% battery left. Today it has 69% left.
The 3G model had 69% yesterday and 68% today.

I wonder what gives for the Wifi model? No settings or anything was changed from yesterday to today...charged overnight to 100% (just like the day prior) and playing the exact same movies for the same length of time.

3 hours: 3G iPad: 83% Wifi: 84% (1% difference)

Keep going! This is helpful. Not sure why other people are being so negative.

Some tests I would like to see is jailbreak vs nonjailbreak. It'd look like this:

Jailbroken WIFI iPad vs Nonjailbreak iPad 3G.

3G data turned off.
 
8 Hours in...

3G: 42% Wifi: 44%. Again the Wifi model is way off yesterday's results while the 3G is practically the same. Very weird and it leads me to believe that the Wifi results were not correct yesterday and the 3G's were and that having the 3G radio on did not have any real effect on the battery life.
 
That implies the battery is going bad at an incredible rate or the OS is acting glitchy with the wifi version.

Oh well...it's my wife's iPad anywa. :p:D

The thing I really wanted to see was about the 3G radio and the jailbreaking. My test shows that the 3G radio doesn't have any effect, even if enabled, it is not in sure. Still doesn't answer if the jailbreak has any effect on the battery. I could restore it and do the test without the jailbreak but it's not really worth the time I don't think. Bottom line is that it still lasts a VERY long time, even if the jailbreak has an effect on it, it's something like 1% per hour at most.
 
This isnt the first time the battery was run down though, plus it wasn't even run down all the way since I stopped the test after 12 hours.
 
10 hours...

3G: 25% WIFI: 28%

The 3G iPad is off by just 1% compared to yesterday's times and has been within 1% of yesterday's times all day. I would say based on that, that having 3G turned on has no effect on battery life or so small that it's negligible.

Not sure what happened with the Wifi model, after 10 hours, it's off by 6% from yesterday and has gradually been off by a bit more at each "checkpoint"
compared to yesterday.

So...I learned that leaving 3G "on" in the settings has no effect on battery life. Still don't know if the jailbreak has any effect on battery life but I would say it does not or has very very little.
 
This is awesome!!!!

How about doing a side by side test with one streaming content from netflix over 3G and the other streaming the same content over wifi - only if you have lots of gigawiggles to waste on your 3G plan of course
 
The 3G radio will use power irregardless to if you have the 3G on or not.

The only power you'll say is because you turned off broadcasting and reception; otherwise the components are still on.

Also may sure your brightness settings are the same; that's the biggest consumer of battery life.

Two things: First, "irregardless" isn't a word. And second, if 3G is turned off on my iPhone, my battery life is infinitely better. So what you say is only going to serve as confusion, as you probably don't know how the iPad is powering 3G. I'd say no matter what, you're going to see better battery life with 3G turned off.

do you have anything to prove otherwise? thinking about it, the 3G would still remain powered. it may be in standby mode, but its still on.

Infinitely is excessive. I've got a 3g also and always turn off 3g when wifi is available but i don't see a multi-hour jump in battery life.
