What actually uses more battery power - WiFi or 3G ?

I've read conflicting thoughts, so I wanted to ask which actually uses more battery power - WiFi or 3G ?
Does anyone leave WiFi disabled all the time?

Thanks for all your responses. I suspected WiFi used more power and you guys confirmed that.
BTW - Michael, 0.5 watts is 500 milliwatts... so you're off base with the comparison of the couple-of-hundred milliwatts for wifi vs. 0.5-1.0 watts for 3G. Excuse me... I used to be an engineer

IPhone not charging and using more battery power while on charger and getting hot

I have an iPhone 4 and have had issues with it charging. This has happened 3-4 times over the past few months, where I put it on the wall charger prior to going to sleep and wake up with 17-20% battery power. Last night I placed it on the charger with approximately 70% battery power. I believe it charged to 100%, I left it on the charger and when I woke this morning the phone was hot (hotter than charging it with the USB) and the power was at 17%. Any suggestions on what I can do to rectify this issue? After the iOS upgrade it did and I reset the phone, ran the power completely out and charged 100%. I don't have any more apps open than usual. Thanks for any help you can provide!

Having a similar problem with my 3G IPhone. Battery life is fine but once I plug it in to charge it won't charge. I have to reset my phone and then it will start to charge as long as I unplug it and then plug it in again. This problem is something that is intermittent. I reinstalled the firmware but the problem did not go away. Something that I have noticed is that when this takes place usually the GPS function cannot find my current location at the same time. Once the phone is rest the GPS is fine. The fact that I have reloaded the firmware and the problem has not gone away leads me to think that this is a hardware problem. Well we will see soon I am going to take it in to get checked out. This is sort of annoying but I love the IPhone it is great!!!!

What uses more battery: Push or Fetch?

I have recently downloaded MobileMe and using it mainly to add / edit my contacts and callender.
Im just wondering, which setting will be best for me, Push or Fetch?
I'll only be editing things on MobileMe about once a day, so is it best to use Push? I.e only using the connection when its needed.
Is it fair to say that Fetch uses more battery life because its connecting more frequently and often for no new data?
Hope this makes sense!
Thanks
James

Push uses more battery power. The second bit of advice from Apple increasing battery life is to turn off Push (the third is to reduce the Fetch frequency).
Fetch, at most, can check every 15 minutes. Push must ping the server frequently to maintain a 'live' connection, so updates can be pushed to the phone as soon as they hit the server.
In your case, Jim's advice seems best - just turn off Push, set Fetch to Manual and check when you like.

Why does OS7 use more battery on iphone?

Upgraded to OS7 from 6.1.4 which was much better on battery life. Why does OS 7 use so much battery and how can I reinstall OS6?
Its using approx 10% of battery life every hour, when not using the phone and all apps switched off, push notifications off etc - if I was actually using the phone and making calls battery will be dead in no time!

why?i rip all my cd's in wma,y does wma files use more battery life?
Due to higher compression rate of WMA. The player will need higher processing power to process it thus the higher battery consumption but it should not affect it very much around 0-5% more only.

Artworks consumes more battery power significantly? Maybe a GOOD IDEA!

I'm searching for ways to improve battery power and...
1. Artworks consumes more battery power significantly?
2. If we found a program that equalize (ROCK for example) all mp3 before copy to iPOD, it discards EQ on iPOD to improve power?
Good idea???
Thanks!

Very insignificantly... to such a tiny degree that it's not an issue.

on iPOD to improve power?

If that's what you want, then I guess it's a good idea. Be aware that raising the eq level also increases the volume. iPods distort extremely easily when the volume going into the amplifier exceeds a certain level.
Once you've run your eq software, be sure to use a piece of software called mp3gain on your files after you do your eq. It will analyze your files and completely losslessly adjust the volume, without even modifying the song bitstream data - magic! This software can handle mp3's by default, and AAC files if you add something else.

But before anyone else thinks of running mp3gain on their mp3's or AAC's... DON'T do it for files that have already been imported into iTunes if you use the 'sound check' feature!!!!!!

Make Spotlight (& the OS) use more CPU power?

I've noticed that a lot of the time that the OS, specifically when using Spotlight doesn't use all of it's power.
For example I have iStat menus displaying the CPU usage. When I do Spotlight searches I'll start typing but before I can finish typing my search Spotlight will start grinding away, not letting me finish what I want to type. But looking at the CPU usage in the menu bar both cores are only at around 50%. I'll have to wait for Spotlight to calm down before I can finish typing my search.
I looked around in System Preferences > Energy Saver > Options & set Processor Performance to highest but it seems a lot of the time the OS doesn't use as much CPU power as it could.
Is there any way to make the OS, specifically when using Spotlight use more CPU power?

Spotlight will use as much CPU as it needs - It really doesn't take that much unless it's drawing image previews, etc.... The other-and probably more important- issue is hard disk speed and whether or not the disk is doing anything else when you initiate the search.

Macbook no more battery power, message displaying mac os x quit unexpected

I had written a topic earlier saying that my macbook was not powering up because i had apparently no more battery power left. when i plug it in to the wall, a message comes up saying mac os x has quit unexpectedly, would you like to send a report... a person answered me saying that i was closing the lid before it was totally closed, and my battery was getting drained. So, finally, i keep making sure my macbook is totally closed before shutting the lid. But it happened to me again today!!! called applecare made me shut it down and press power button for 5 seconds. Im not really confident that this is going to fix my problem? Has this happened to anyone??? Please help me!

well i just called applecare, and he made me shut it down with no battery in it or power cord, and he made me press the power button for 5 seconds, so im gonna see what that does, but i dont really know if thats gonna work, why did he make me do that? he wasnt very friendly and didnt really explain anything

Which drains more battery power, Wi Fi or 3G?

If you had these on independently Which drains more battery power Wi Fi or 3G?

You can read Apple's recommendations on iPhone batteries here:
http://www.apple.com/batteries/iphone.html
From the specs: iPhone 3G offers up to 5 hours of talk time on 3G...6 hours of Internet use on Wi-Fi. Not stated there is that internet use on 3G is less than the 5 hours of talk time...

HT4759 Does I Cloud use more battery life

Does I Cloud use more battery life?

I suspect that if you turn on the backlight to look at the artwork, the backlight uses battery juice. I doubt the physical presence or absence of album art uses any more juice.
BTW, I don't believe the album art uses a "**** of a lot of MB". It probably only adds a few KB to the song file since it is so small.

TS1388 My battery on my macbook pro all of a sudden keeps using the battery power really quickly, so I am having to rechareg it constantly. Does anyone know why this occurs or how to fix it. I have used all the energy saving tips.

Hi My battery on my macbook pro keeps running low on power very quickly and I have to keep recharging it. This has never happened before. I have used all the power saver options, but it keeps happening. Can anyone help. The battery seems to be losing power even when it is turned off.

Hi BigThinker,
How old is your Mac? If it is an older one, then the battery may just be dying. You can check by clicking on the Apple in the upper left-hand corner, then clicking on About This Mac>More Info>System Report, then click on Power (about half way down the list). At the top of the resulting display, you should see the following type of info:
The Health Information will tell you if your battery is going to need replacement soon. If it says Normal, then it is not the battery.
Cheers,
GB

Adobe CC using excessive battery power

I updated to the latest version today. Now I see this:
This is a feature of Mac OS X that figures out which apps are consuming a lot of battery power.
As you can see CC has made the list while for example Dropbox has not.
It didn't use to be on the list. I think its new for the latest version but I'm not entirely sure.
Could it have anything to do with your latest improvements to sync reliability.
Here is it is the the Activity Monitor's energy tab. As you can see it takes quite a lot of energy.

See https://en.wikipedia.org/wiki/Advanced_Configuration_and_Power_Interface When you think the laptop is powered off it's actually in ACPI Power State S5 with power being supplied to the power button and some of the USB sockets. So, when you shut down the laptop and then removed the power cord, if the BIOS version was lower than 1.13, the laptop was still draining the battery.I followed your suggestion, and it seems solving the problem, thank you. However, another problem arises just recently. When I was playing a game on my laptop, the battery capacity is decreasing when the AC power connected (as described by both lenovo and Windows battery gauge). I post this problem in https://forums.lenovo.com/t5/11e-Windows-E-and-Edge-series/ThinkPad-E455-Battery-Capacity-Reduced-When-Connected-to-AC/td-p/2106218. Oddly, the problem (seems) does not occur when I quit the game to windows. Why was this happen?

IPhone 4S' iOS6 uses more battery juice or something else?

Hello.
My client's couple years old iPhone 4S (Verizon carrier)'s battery life has been less with the latest iOS 6.x version than iOS 5.x (upgraded iOS a few weeks ago). I re(called/member) that people had this problem when iOS 6 first came out. Is this problem/issue still not fixed as of today? Or is it just a coincident that its battery is old and probably needs to be replaced?
Thank you in advance.

Within the last hour, I took a lot of photo(graph)s (a couple of panoramas) of the local outdoors with no flashes and with HDR to experiment. I also did some managements to delete bad shots and used its MMS a few times. The old iPhone had about 100% of battery power, and now it is 43% after taking about 50 shots!
The camera DOES use a lot of power, and it uses it as long as the camera app is open, not just when you snap a picture. So the battery usage taking pictures is not a good measure of the battery capacity. If you take it to an Apple store they can test the battery.
Ah. What is a good way to test its battery usage without going to an Apple store which is not local?

Why does Magic Mouse use much more battery power than the keyboard?

I have the Bluetooth versions of the keyboard and the Magic Mouse. I use the same rechargeable batteries in each. Yet the mouse has now come to the end of a THIRD set of AAs, while the keyboard still has 60% of its first set.
Why? They are both constantly in use, so why does the Mouse drain batteries so much faster than the keyboard? Viz: the mouse about once a week (two, max), while at this rate, it will be another month or more before the keyboard drains.

Actually I don't! I consider myself a 'power user' in that I will always use the keyboard first, and I learn keyboard shortcuts for nearly everything I do regularly.
I would guess my use is 50:50 at worst?

What happened to my battery power??

What is going on with my ipod touch's battery? I won't use it or turn it on for days, yet I'll turn it on and suddenly I'll have 10% battery life. I've read other suggestions about turning off wifi and turning off the push function and STILL my battery died. It died quicker, actually.
Why is it doing this? It didn't do this until the new update...

When you say "I won't use it or turn it on for days", do you mean you leave it asleep, ie you don't "power it off" with the red slider? If you don't power it off, then it is not off, it is in sleep mode. If you have wi-fi turned on or - even worse - push turned on, I can see how your power gets drained after a few days.
If it was only asleep overnight with these conditions and it drained to 10%, that would be a problem. I suggest, if you aren't using it often (heaven forbid!) you turn it off.

Should i use all battery power in the ipad2 before charging

I was wondering if I was to charge my ipad2 when its like at 60% will my battery like get ruined or anything?

Wisdom is wrong in witch letting you battery die you are not just using a certain amount of battery all the time in which letting it die will use that little extra and make recharging the battery faster and better for the battery. And how long it last.
Rbrylawski please reply if you actually know something other than what people tell you
I submit that rbylawski was giving you an explanation provided by Apple and I further submit that Apple knows more about their batteries than you do. In a nutshell, your battery explanations are 100% incorrect and we would appreciate it if you did not spread misinformation.
