Why battery life decreases significantly when I use Safari?

I upgraded to El Capitan 10.11.5. on my Macbook air early 2014.  Just when you open Safari, it is listed as using the significant energy and the battery life decreases by several hours.

I have no software extensions or third running.  I didn't have bugs or other problems since the installation of El Capitan, just this matter of battery life.

If anyone has any recommendations on how to investigate this, I would be very grateful.  Thank you.

Please, back up all data before proceeding.

Triple-click anywhere in the line below on this page to select this option:

~/Library/Safari

A right click or Ctrl-click on the line and select

Services ▹ Open

the contextual menu.* should open a folder named "Safari". Quit Safari runs. One or more files in the open file must have a name begins as follows:

History.DB - wal

Move these files and only those who, in the trash, leaving the window open. Restart the application and test. If there is no change, stop again and place all other files with a name starting in 'History' of the Safari folder to the trash. The browser history will be empty. If possible, restore the file named "History.db" from an earlier backup problem.

* If you do not see the item context menu copy the selected text in the Clipboard by pressing Control-C key combination. In the Finder, select

Go ▹ go to the folder...

from the menu bar and paste it into the box that opens by pressing command + V. You won't see what you pasted a newline being included. Press return.

  • Why the AutoCorrect shuts off when I use the Smart keyboard on my iPad Pro?

  • Crashes when you use safari

    MY Mac Pro 2009 crashes when you use Safari. I can tell when it is about to happen. The screen will start to Flash and the mouse still moves, but you cannot select anything. Sometimes I can get it to unlock by pressing the ESC key.

    When the freeze on Safari, note the exact time: hour, minute, second.

    These must be run as administrator. If you have only one user account, you are the administrator.

    Run the Console application in one of the following ways:

    ☞ Enter the first letters of his name in a Spotlight search. Select from the results (it should be at the top).

    ☞ In the Finder, select go utilities ▹ of menu bar or press the combination of keys shift-command-U. The application is in the folder that opens.

    ☞ Open LaunchPad and start typing the name.

    The title of the Console window should be all Messages. If it isn't, select

  • Questions about privacy and security when you use Safari for Windows

    I have Itunes + Quick Time Player installed to download music and some time ago I had the opportunity to download Safari for Windows.  I used it a few times, just out of curiosity, and I noticed that it is much faster than IE7, so I plan to use it regularly, but before that, I have a few questions:

    -someone at - it tested (or uses) Safari for Windows, and what are your results?

    -What is save to use as Firefox or Opera, both recommended as alternative by our experts at the HijackThis forum?

    -the programs that I installed (Online Armor firewall, AVG 8.0 suite, MBAM with protection in real time enabled RogueRemover Pro with immune protection enabled, WinPatrol, SpywareBlaster) offer the same protection when you use Safari for browsing?

  • Battery life will reduce when USB 2.0 device is connected

    I found that the battery life of the computer laptop centrino duo will reduce by 80 percent when you connect a USB 2.0 device. Is this true?

    Microsoft has agreed that there are some issues with the USB 2.0 driver and registry. This problem still exists on the laptop centrino duo?

    It is not known to me and I can t believe that self-government will reduce by 80% when the USB device is connected.
    Is the USB ports power USB devices.
    Of course, additional USB devices waste the energy of the battery and battery working time is shorter if USB devices are connected.
    But it s not 80%

  • I updated my ipad ios 9.2.1 and when you use safari, it crashes

    I've updated 9.2.1 on my ipad and now my safari crashes when you use the keyboard

    Here's my own list of the fixes suggested trying who helped many former users of iPad.

    A warning:

    I make no warranty, express or implied, that any PART of my patches suggsted or solutions will fix/restore each older iPad on his former status of operation

    Try to reset all the settings in the settings under general app and in the right column under restore.

    Try stories reset and delete/reset the caches in all web browsers you use.
    If you use Safari, these features may be in the application settings under Safari.
    Other browsers have their settings inside the running application itself.

    If your iPad has been activated for iCloud, in the application settings under iCloud, to the right, under iCloud Drive, type in iCloud drive and make sure that Safari is off to save data from Safari to iCloud by car.

    Also, under iCloud in the application settings, in iCloud Drive, turn the feature off saving for all other desired apps DO NOT the data automatically on iCloud drive.

    For additional questions to Safari, try disabling Safari Suggestions found in the settings app in the control panel settings of Safari. Press Safari and in the right panel, look for the Suggestions of Safari and turn this option off to disable this feature.

    If you are using Safari is always causing issues.
    Try changing / using web browser third another, different.
    I do not use iOS Safari too much more because I found it cause me headaches on some Web sites, regularly, to visit.
    I commonly use another third party browser, perfect browser (there are others that can suit your style better web browsing, so look all first to see what third-party browser may work better for you) and I have never experience many questions that Safari was originally.

    In the application settings tab general, right under the spotlight sesrch, try disable the search under the applications who really don't need a research, as some games, remote controls, apps that are really useless to be searched, etc., in order to reduce the list to Spotlight search

    Try to turn the reduced movement.
    This is found in the application of settings in the general tab, in the left panel.
    In the right panel, look under accessibility, look to reduce the Motion and turn this feature "On".
    You should see a significant performance increase on all models of iPad 2, 3 and 4.

    In the application settings under the general tab, in the right column, search background App update and enable this setting to "off".

    Try a hard reset of your iPad by simultaneously pressing buttons Home and sleep/wake button until your iPad goes to the dark and restarts with the Apple logo, then release the buttons.

    Good luck!

    First backup your drive hard as soon as POSSIBLE. You may well have a defect of the hard drives.

    Then start in the recovery volume (start with the command + R keys), select disk utility and run the feature of first aid on the disks.  If you receive a message that x number of errors were repaired, rerun the first aid until there is no errors detected and repaired.  Restarts normally and restart Etrecheck.

    Regardless of the results of the second report by no. means that you should not have Apple test a free diagnosis of your Mac.

    Thirdly, launch Safari with the SHIFT key is pressed and see if there is an improvement in the performance of Safari.
