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.

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

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.

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.

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!!!!

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?

Does Moc OSX Lion use more battery than Snow Leopard?

Ever since I have updated my MBP Early 2011 (2.2 Ghz Radeon 6750) to Lion, my battery life has gone down tremendously. I used to be able to get a solid 7 hours in (light workload ei. web browsing) and now I'm only able to get 3.5 hours MAX. I'm currently running 10.7.2 and the problem is still there. I have gone through around 200 cycles so it's not like 1000's of cycles or anything. Is this just me or are other people exeriencing the same problems? I plan on going back to snow leopard soon if there is no fix to this.

I have had my MBP since July 2011, and am at 22 cycles.
You must run soley on battery charge, almost never plugged in.
Are you running your battery very much down (10%-20%) before re-charge , or recharging at about 40%?
Running Lithium-Ion batteries almost dead create a "memory" that can make your MBP unchargeable.

What is the difference between PUSH and FETCH

I am a little confused. I use my iphone for both my personal POP email accounts and my business exchange account. I am trying to save as much battery as I can so I turned off push and set everything to manual...but now when I try and get may mail....it either says "connecting" or "checking for new mail" at the bottom of the screen and nothing happens from there.
What is the best way to setup this situation for the most battery life? I don't need it to automatically download emails just when I open the email accout would be nice.
I also noticed that when I delete an email from my iphone on my exchange account, it also deletes is on my desktop at work...I need to turn this off...is it possible?

Hi maxum25,
The difference between push and fetch is that:
When using push, the server sends a signal to the iphone and lets it know that an email is coming its direction. Kind of like receiving a call. The iphone does not need to do anything except receive the email.
When using fetch, the iphone has to wake up every so often and send a request to the server to see if there is any new email waiting for it on the server to download. This takes more time because the iphone sends a request, the server says yes there is some, the iphone says ok give me the new email.
Now the exchange email uses active sync to keep all changes on the exchange server and mobile device in sync. This is automatic and is the nature of exchange and active sync. In order to keep this from happening you would need to talk to your IT dept. and see if they have an imap or pop alternative. Even using imap reflects the changes back to the server.
Hope this helps.

I have a macbook unibody. the dvd driver cannot pull in a cd and when i ma pushing it a little more it pushes it out! does anyone knows what is wrong? or how can i fix it?

hi everyone!
i have a macbook unibody and when i put a cd on the dick driver in it doesnt pull it , but when i push it in a little more it push it out!
does anyone knoes what is wrong? or how can i fix it?
thnx

I'm not sure about your question, it's seems somewhat unclear, but if the above command doesn't work another you can try is using the diskutil command as follows:
"diskutil list"
or
"df -h"
(without "" quotes)
find where the cd is (usually /dev/disk1 but not always depending on what else you have pluged in)
then simply use the 'diskutil' command with the 'eject' argument specifying the device found from the previous command '/dev/disk1'(or what ever your optical is labeled as).
If this isn't your question, I have a macbook unibody late 2009 model and the strangest thing happends, If I downgrade to 10.6.1 my optical drive works fine anything 10.6.8 and above ejects my disk immediately, I have also tested my optical drive out on other OS's such as various linux distro's. Therefore I have come to the conclusion its a bug. - just food for thought. Hope some of this helps

Stratosphere consuming more battery when not in use

Does anyone know what might cause this and/or if there is a fix for this?

sorry for slow reply but in order the answer to your questions are: 1. i get about 4-5 hours of idle time off the charger 2. yes i do 3. yes i use the default one that came with the phone, called program monitor 4. this is a replacement phone as my last phone had battery issues as well though it had problems with being active as well as passive but back to the point the phone did not come with a battery
oh and i did the math my passive time is close enough that a geusstimate of the math was that it was useing more. it isn't quite useing more but it is very close
edit: this problem did not occur when the phone was first received i got about 3-4 days of normal behavior and then it went and started this

When you double click the circle buttom, and the little bar pops up from what you have been using... is it using data while being in there? is it a good idea to minimize evertthing out of there often so its not using more data ? or does it not matter?

Not sure if it uses data, but that allows you to multitask. To save battery life you should close out of all the apps.

TS4083 So what is the fix? When I delete on my computer I want it to delete on my phone and iPad. Do I put everything on push or fetch?

So what is the fix? When I delete on my computer I want it to delete on my phone and iPad. Do I put everything on push or fetch?

This is a function of the type of email account you are using, not whether you have it set to push or fetch. POP email accounts cannot sync changes across devices. Having changes such as deleting emails synced to your other devices is a feature of IMAP and Exchange Accounts. POP email accounts won't do this. If you're using a POP account, you'll have to switch to an IMAP account such as iCloud email or Gmail in order to do this.

Why is iOs 8 using so much more battery life on my 5c??

Ever since updating to iOs 8 with the supposed bug fixes, my 5c uses MUCH more battery life and I am NOT on it during the day at work except to make 4 -5 short phone calls!!! I hate it!! Wish I'd never updated. I have decreased screen brightness, turned off notifications for practically everything, and usually only play a little Solitaire and check FB for about 15 - 20 min. each evening. Also, FB isn't working at all since I've updated. I can open it and see old stuff but no new posts to FB. Come on, Apple!! This isn't what we wanted. Believe me, lesson learned. I won't update ever again to a new Os. This is ridiculous. I loved my 5c and it was working fabulously with great battery life!! I only bought my first iPhone 6 months ago and WAS in love with it UNTIL NOW!! Does anyone have any suggestions???

Basic troubleshooting steps clearly outlined in the User Guide are restart, reset, restore from backup, restore as new device.
Have you tried ALL the troubleshooting steps? If you have and you're still having problems, then you'll need to bring your phone into Apple for evaluation and possible exchange.
There is no supported way to downgrade the iOS.
