2.0 battery drain on touch

[globetoole]

last two days with 2.0 have been big battery drains. Right now I am down 30% in about an hour of music and Internet. Seems too fast and touch is pretty warm. Anyone else notice that?

[lakerboichris]

yer i hav the same problem

[GeezerPod]

I noted a quicker battery drain too. Looking at new features I noticed that the new 'Fetch New Data' feature was on by default. Turning it off seemed to stop the aggressive use of battery.

No technical evidence though. Maybe I'm wrong, but my battery drain is good again.

Mine has been draining quickly, but then I can't stop playing with the thing. My wife is getting jealous!

[mcdongato]

I noticed the same thing and am hoping it's the push data function. I've set it to fetch manually. We'll see if that takes care of it.

[paranoidxe]

Yup, I've downgraded to 1.1.2 until a new 2.0 release comes out..2.0 is far too buggy.

[Dogg Thang]

What is this 'fetch data' feature?

[globetoole]

I tried the manual fetch and it did help, so far. That is fine for touch but wouldn't make me happy on iPhone.

[mcdongato]

I'm still getting a quick drain, but I've been streaming audio from Pandora for the last hour or so. I'm guessing heavy wi-fi really kills a battery?

[archurban]

you just go to settings > general, then turn off fetch new data option. it's new feature that automatically push company's email, calender, any data files every time under wifi, or cellular connection. it's like background process. so even you turn off iphone or ipod touch, it still tries to get access. so better turn it off.

[globetoole]

Ok - one day later - still having drain problems. I turned off fetch. Today, I used the Touch for 1 1/2 hours on a plane. No fetch, wi-fi was turned on, but not connected to anything (natch) and I was down 30%.

During this time I watched one show, and played a game for 15 min. The touch was pretty hot.

I turned off wi-fi and that did seem to cool it off - but with no fetch what gives?

If you're not constantly connected to a WiFi network, then the touch will keep looking for an active WiFi all the time, meaning additional battery drain. That's always been an issue with the iPod touch, not just after the 2.0 update.

Having said that, I do notice the battery drains much quicker now after I updated to 2.0. I have "Push" enabled, so that partly explains why.

[rowuncw]

I'm just throwing something out there, but could it be a new application from the store that constantly uses wifi to update/get new data?

For future reference, having a Wi-Fi application enabled on a plane is illegal!!!

Illegal, or just against rules set by airline companies? In the whole world or in certain countries? :)

Same here- battery seems to drain quite a bit faster. If I'd have known, I would have held off updating. Apart from that, seems more stable now- not thrown out of Safari like I was before.

why would you leave wi fi on if you don't use it? It uses more power if it can't find a service.
moreover why would you have it on a plane?:confused:

[Razzy]

Dmonk is right, wifi takes a lot of power on either end. Whether, you are browsing through Safari or if the Wifi is off. There is no way you will find a connection on a plane lol.

I am afraid some of you may be missing the point. It is not that WiFi takes extra power. It is that with everything else (seemingly) equal, the 2.0 firmware seems to consume battery quite a bit faster than the old firmware. That's what a lot of us are complaining about.

[IDN101]

Seems I may have been hasty in my statement that I'm experiencing quicker battery drain with V2.

As a test, I fully charged my Touch yesterday and then left it playing through a huge playlist- Volume at 30%, no wifi, screen off.

So far it's managed 21.5 hours- and it's still playing. So I'm quite happy with battery life.

I just turned this off....I prob would have never noticed it

[buttersideup]

Mine has been draining very fast, but I think it's due to playing CPU intensive games like Enigmo.

[dmonk]

(update)


Some others at the Apple forums have mentioned that Location Services option is also causing battery drain. Anyone know what that is? I heard some guy had his Ipod in sleep mode and it was still gathering data for something while that was on. I'm guessing it only affects wi-fi but I have no idea if its buggy and trying to be always on in general.

Anyone know exactly what that does?

You registered to say that, and it's not even true?!?!

It's against airline rules, but it's not against the law, as far as I know. I seriously doubt WiFi use from an iPod touch is going to cause the plane to crash immediately. You have a minute or two to switch it off before the Air Marshals beat you up and throw your out an airlock.

(Taken from here (http://appleseed23.blogspot.com/). )

Follow these tips to get the most battery life out of your iPod Touch:


1. Under Settings turn the Brightness down to the lowest comfortable reading level.


2. Turn off Wifi if you are not using internet.


3. Switch Fetch New Data to Off.


4. Under Settings > Music > turn off the EQ.


5. Use your iPod Touch often! - Keep those electrons moving.


6. Keep your Touch topped off (battery fully charged).


7. Charge your touch to 100%, then run it until the unit shuts off. This is called a charge cycle. You should do this at least once a month.


8. When not actively using the screen, use the Screen/Lock button to save power.

Actually it is true. Unless a "transmission device" is certified by the FAA it is a violation a several Federal Aviation Regulations(FAR's) to operate on an aircraft "during flight operations". The last time I checked, the iPod Touch is not FAA certified. This will change shortly with several airlines starting to offer wi-fi service based on a "shielded system". Airlines have been slow to adopt this in part because the shielding of avionics costs weight, which costs money every time the plane flies.

As for whether or not a Touch's wi-fi would cause a plane to crash: Do you really want to take that chance? The first sign you're going to have that it is interfereing with the navigation system is when the plane flies into a mountain or something. And as pointed out, unless you're a plane with internal wi-fi, you're not going to pick anything up. It's just one of those situations where you can choose to walk around like a know-it-all, pompous ### or not. The choice is yours.

why not try this from apple

i have something similar for my 32 gig video ipod, when low i plug the ipod lead into the usb charger which is charged via 2 AA batteries, and let it charge fully, keeps me going on long flights/trains etc

My question is, does a violation of the FAR's constitute "illegality"?

Even if it does, the FAR's only apply within the U.S. territory. In that case one could say using WiFi on board is illegal in the U.S.. :)

The charge would be "Interference with Aircraft Operation". It is a felony. It can earn you up to 10 years in federal prison. So yes, it is a crime. It applies to all flights arriving in, departing from or transiting over the US. As for what the rest of the world does.....the accident rate for European and Asian carriers is 10 times that of US-flag carriers. So maybe the FAA is onto something when it comes to safety.

Again, as stated in my original post, unless the aircraft has wi-fi, you're not going to pick anything up so what's the point besides draining your battery faster?

I thought it was only phones.

[Aussiergman]

I've been flying alot latley and most times on airplanes they ask for mobile phones/mp3 players and wifi units to be switched off during take off and landing,

And to add to that list--some airlines even request that portable GPS devices be turned off as well.

You will get more power drain while surfing the web or using WiFi. I have no problem with the quick power drain though. I have my handy adapter with me quite a bit.

[thedodgyguy]

I've always had Wifi turned on all the time.


I left home with a fully charged Touch, and today's use was 1 hour of podcast listening, 20 minutes of video and no more than 5 minutes of Wifi web use. I don't have push enabled.


Charge was down to about 20%. Not down by 20%. Clearly something is b0rked.

[globetoole]

ok sorry to fire up the plane safety crowd. 2.0 drains battery quite fast if you use any apps even if you turn off fetch. . If you stick with music, video and such you are fine.

[thedodgyguy]

I think there is major b0rkage. I played a portion of a movie - half an hour max, left it for two days, and it's flat.

[joker0153]

I'd suggest turn off wifi, push and location services. then test you battery again.

[thedodgyguy]

[Stereobot]

not sure if anyone is still paying attention to this thread, but my Ipod touch 32GB 1st gen loses battery power very quickly, especially using apps that stream music.

Looks like I am not alone here on that... I used up about 50% of my battery listening to music streaming from an online radio station using an app, I was only listening for maybe 30 - 40 minutes!!!

This can't be right..

Just a quick update on this issue. Wi-Fi on non-shielded planes is illegal in the US as you pointed out....but stupid everywhere.

Qantas probes laptop link after 300 foot plunge

Passenger laptop computers are now being investigated as a possible cause of the Qantas mid-air emergency off Western Australia on Tuesday.

The Airbus A330-300, with 303 passengers and a crew of 10, experienced what the airline described as a "sudden change in altitude" north of its destination on Tuesday. The mid-air incident resulted in injuries to 74 people, with 51 of them treated by three hospitals in Perth for fractures, lacerations and suspected spinal injuries when the flight bound from Singapore to Perth had a dramatic drop in altitude that hurled passengers around the cabin.

In July, a passenger clicking on a wireless mouse mid-flight was blamed for causing a Qantas jet to be thrown off course, according to the Australian Transport Safety Bureau's monthly report. Safety investigators will now ask passengers if they were using any electronic equipment at the time of this latest incident.

"Certainly in our discussions with passengers that is exactly the sort of question we will be asking - 'Were you using a computer?'," The Courier Mail quoted an Australian Transport Safety Bureau (ATSB) spokesman as saying.

The ATSB said the pilots received messages about "some irregularity with the aircraft's elevator control system", before the plane climbed 300 feet and then nosedived. "The aircraft is then reported to have abruptly pitched nose down," the director of aviation safety investigation Julian Walsh said.

The plane was forced to make an emergency landing at Learmonth air force base near Exmouth in WA.

Sorry, but is this thread titled "2.0 battery drain on touch" or is it titled "what is and what is not illegal on airplanes?"

Come on... stay on topic or start a new thread somewhere else... :mad:

[keithnyc]

Yup, wifi is a battery sucker. I went from a full charge to the dreaded warning in just 1 1/2 hours of wifi. That's why wifi battery life isn't advertised (like the skillion hours of music and the 5 or 6 hours of video). They advertise the "functionality/availability" of wifi.

Oh and not to get off the thread topic, but to the folks that were claiming the wifi caused the plane mishap, I'm like, Puh-Leez..... If airlines think they could avoid a lawsuit by claiming that people were sipping beverages through straws too aggressively, thereby causing the cabin to de-pressurize to rapidly, they would.
