Battery draining fast after the update of El Capitan 10.11.6

I get usually around 7-8 hours of life of the battery until last week.

Now, it does not go beyond 4 hours. Here is the list of applications that use years.

I use applications all the time:

1 safari

2. prospects

2-3 hours per day:

3 adobe Dreamweaver CC

4 Filezilla

sometimes

5 Skype

I don't know what happened now, I've updated El Capitan 10.11.6 updated, I see one done drain. I tried Command-Option-P-R, but unlike the previous versions of the OS (Yosemite), this time I get a different screen, where everything makes me panic.

I don't want the operating system reinstalled, taken an old backup of time machine etc. I just need better battery life. Can someone me hint at what could have gone wrong. I'm ready to send more details, according to which ask you to investigate this.

Thank you

Try this first: reboot safe mode (takes awhile) and restart normally afterwards.

Safe mode: https://support.apple.com/kb/PH21875

If this does not help: open the activity (from utilities) monitor and verify if a process uses a lot of CPU power or energy: https://support.apple.com/en-gb/HT201464

If all fails, send a report of Etrecheck in a response: http://etrecheck.com

  • After the update to El Capitan 10.11.6 I'm more able to use Excel

    I've updated a Mac Air to version 10.11.6. After the upgrade I'm more able to delete rows in Excel. The error is "Alert not enough memory" file is only 4.7 MB and air shows that I have 1 GB free memory. Is this a bug, and if so is there a work around available? I came to a standstill. worked quite happily on the sheet before the upgrade

    Try to reinstall the update by using this file: Download OS X El Capitan 10.11.6 Combo Update. It can solve the problem, but if it is not the case, then you must reinstall OS X. It is not a bug in Excel because I did not have such a problem arise on my system. However, an alert memory you reported is an OS X error alert that you have not enough memory to continue. Quit all other open applications to free up more memory. See if that helps. Also make sure that report is not disk space.

  • Two "photo library" after the update to El Capitan

    Hello

    I found two "photo library" file in ~ / images /, one with the old icon names "iPhoto Library", the other with a new icon of Capitan, called "photo library".

    Created and last updated date match each other.

    I guess that El Capitan duplicate my library during installation. I'm a little surprise to bite, it has not removed the old...

    These files are huge: is it safe to delete the old one?

    Thank you

    These files are huge: is it safe to delete the old one?

    Libraries to think big, but they share the storage for images and use less than the total size of the disk storage, see this support document:

    Photos saves disk space to share images with your iPhoto or Aperture - Apple Support libraries

    and also: Six colors: the (hard) link between iPhoto and photo

    If you delete the old iPhoto library, you won't win a lot of rear storage. It is save to remove the iPhoto library, but I wanted to wait burn bridges.  Wait, are you sure that the migration went well and no pictures are missing.

    In addition, you may need to complete your projects in iPhoto, the projects do not migrate. How many Photos handles content and metadata for iPhoto and Aperture - Apple Support

    And if you notice, that you do not like the pictures and want to return to iPhoto, you'll need your old library.

  • BlackBerry Z30 battery draining high after update 10.3.2.2474

    The battery drains quickly after the 10.3.2.2474 update.  The monitor of the device shows that it is the standby process that uses between 25% and 40% of the battery.  This process uses a good amount of CPU.  I tried to restart the unit a couple of times to see if that solves it, but it doesn't.

    Is there a fix or the means to return to the previous version of the OS?  I can't even make at 15:00 without having to recharge my phone.  So much for the famous BlackBerry battery life...

    It does not allow that BlackBerry charger provided with the new phone is only 850mA and the phone does not recognize as a BlackBerry charger (aka, it takes a long time to load in the middle of the day, when it is low).
