Removing apps from multitask bar improves battery life!

I was loosing more than 5% per hor with the phone unused. I upgraded to iOS 5.0.1 and the battery life improved a bit, but no by much. Then I killed all the processes running in the background in the multitask bar and oila, my iPhone 4S has a much better battery life. It seems to drain ay 1-2% per hour now. Actually I just left my phone on all night, without charging, and in 10 hours it has only lost 3%. There can be a LOT of these backgrounded procs since they restart after a reboot of the phone and thus build up over time. I had about 30-40 when I 1rst checked. It doesn't seem stop the functioning if apps  like the timer. I tested the timer, i.e., I set it, killed the background proc on the multitask bar, and it still was counting down the original time set, thus I really don't know what deleteing the apps from the muultitask bar does, it doesn't seem to really kill the process, but deleting them really changes my battery ussage drasitaclly, for the better. If this is the problem it could account for the differences in users for each user will have a different set of background processes running. Anyway try it and see if it works. Mileage varies with ... blah blah.

Songs and apps stored in the iPhone have zero to insignificant effect on battery life.  The User Guide is here.

    Any tips on how to improve battery life on new macbook pro?

    It all depends on how much you plan to run on battery power. If you don't use it often, set yourself a reminder to let it run unplugged about every couple of weeks to aboout a 40% charge and then plug it up and let it charge back to 100%. If you'r'e a frequent battery user (like me) don't let your MBP discharge to the point where you're running on reserve power - down to about 30 minutes remaining and then charge it back in.
    I have over 130 cycles on my computer and I've just had it since March. Even though my battery health was 102.2% when I got my MBP, it's still at 98.8% health and I'm still getting 7+ hours out of my battery. To get the longest use when under battery, keep your activities to low-CPU intensive apps (browser, email client, word processor, etc.) - Internet surfing alone, and not watching a lot of online videos, will give you mor ebang for the buck. You can also check your battery health in 'real time' by using "Battery Health" - free from the App Store and you can make sure that you're running on integrated graphics, which uses less power, by downloading Cody Krieger's exceptional gfxCardStatus.
    Keep your screen brightness down to about four ticks and your keyboard backlighting to one tick - should work fine.
    Good battery health to you,

  • Few problems with the dock. Creating App stack, and removing apps from dock

    OK.. I am running leopard 10.5.4, and decided I wanted to use the app folder as a stack. I made my new folder with the alias' inside. However, when I went to move it into the dock, 9on the right side of the sizing bar), the other stacks failed to shift out of the way, so I couldn't add it in.
    Another problem is that I can't see to remove apps from the dock. I have admin rights, and they are not active, hence the desire to get rid.
    Anyone have an idea??

    Erm... Doh! had dock 'locked' in Onyx...

  • Removing apps from devices in itunes

    Hi all, first time and hopefully last time blogger but if IT’S BROKEN I’ll be back. I have 3 IOS devices (iphone 5, ipads 2 & 3) all have been updated to the
    latest IOS software. These devices are synced with a PC which has the latest itunes software. I can’t remove any apps through itunes for any of the devices
    (e.g. sync with itunes then highlight the apps in the app screen but it won’t change to “will remove”).
    Does anyone know why apple breaks (it’s broken) these interfacing software issues. Why change things to be difficult , aren’t these software
    updates meant to be improvements not hassles

    Until a couple of days ago, I had never seen this in iTunes. This is not exactly what you are talking about but it is somewhat related. I found this to be very odd. The long and short of it is that I could delete apps from my iTunes library, then sync my iPad with iTunes - and even though the apps were no longer in the apps list when the iPad was connected to my Mac, with iTunes running and with the iPad selected under devices - they were not removed when I synced.
    Take a look.
    How do i prevent removed apps from syncing when connecting to iTunes

  • How do i prevent removed apps from syncing when connecting to iTunes

    I've "removed" apps from my iPad to free up space but when I connect to my computer, the apps "appear" to still sync. 
    To the upper right of the screen, it will show there are 65 apps (I removed 20 apps).  These are active apps and that is correct  When I click on the status bar at the bottom of the screen (the Apps section), it shows there are 85 apps taking up space on my iPad.
    Also, where the apps are listed, the apps that were "removed" from my iPad air have an option to "Install".   I don't understand why they're still syncing.  TIA for your help!

    This does not help but it does offer some insight. I have NEVER noticed this before. Take a look at the dialog box in the is screenshot. Note that it says that even if the app is deleted from the iTunes library, it will not be removed for any iOS devices when you sync.
    As an experiment, I deleted the AOL On app from my iTunes library and followed the prompts to put the app in the trash - not keep it in the mobile sync folder. I synced my iPad - and the app is still on the device even though it does NOT appear in my list of apps in iTunes when the iPad is connected and selected. I have never seen that happen before.
    If the app is not in your library, I always assumed that it would be erased when you sync since it is no longer in iTunes. I deleted the app in iTunes and then deleted it on the iPad and then synced again and now it is gone everywhere.
    Bizarre....

  • HT5919 How do I remove apps from App Store after update in IOS7?

    After app update, all app icons are remaining in App Store. Is there a way to remove the icons as in iOS 6?

    There is no way to remove apps from your purchase history. It simply cannot be done. You can HIDE apps from the purchased tab, but you can NEVER delete them.
    iTunes Store: Hiding and unhiding purchases - Support - Apple
    As for the updates not clearing, try closing the App Store app and reboot your iPad,
    Go to the home screen first by tapping the home button. Double tap the home button and the recents tray will appear with all of your recent apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button or anywhere above the task bar.
    Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

  • How do I remove apps from my app store history after I have deleted them from my iPad?

    After trying an app and deciding that is isn't what I want and deleting it, I see that it still shows up when I look at my "purchased" apps in the App Store.  I'd like to purge them from my device's history.  I don't want them saved or backed up by iTunes, if that could even happen.
    Also, App Store on my iPad always shows on its icon that I have more updates than I can find when I  go into App Store.  For example it may show 2 updates available, but when I go into App Store it says all apps are updated, yet the icon still shows 2 when I return to the home screen.  Is this related to the issue above?
    Thanks,
    Bill

  • How can I remove apps from my iPad

    How can I remove apps from my iPad? It does not have the little "x" option on the iPad like the iPhones.

    It works just the same as an iPhone. A long hold on an icon will cause them all to start wobbling, drag to move around or tap the X to remove.You can't remove any of the built-in apps so these won't get an X to tap.

    How can I remove apps from my iPhone 5 home page?

    Tap and hold an app until they all start to wiggle, then tap the black "x" on the apps you want to delete from your phone, or drag them to the edge of the screen if you want to move them to another screen rather than deleting them.  Finish by tapping the home button.

    Hello,
    I have been searching all over but I can't find a post on how to remove apps from the iPhone App Store purchased list. I have been able to do it in the past by swiping the app in the purchase list and selecting hide but it appears this function is disabled... Does anyone have any clue on how to do this now. Thank you
