Yosemite Battery Drain

Either post it or stop trying to persuade people that it exists. If you can't it just confirms that you made it up.

Continuing to spread FUD is insulting, why don't you back up your claims, shouldn't be difficult, you received it.

Ok then. Let's put some topics here.

1- Have you read ALL the 36 pages?

2- You just ignored all the other comments and gave me a completely stupid answer to my last comment (that big one I did).

3- If I could get the recorded conversation from Apple, I would.

4- If you think theres no problem with Yosemite only because YOU don't have it, then, sorry but you don't understand NOTHING about software.

5- The problem exist, don't matter what you or me say\think.

6- As I said, feel free to keep trying to find a solution using methods that all the others here have already tryied. The wast of energy and neurons is yours (if you have any...).

3- If I could get the recorded conversation from Apple, I would.

You're also unable to back this claim up?

5- As I said, feel free to keep trying to find a solution using methods that all the others here have already tryied. The wast of energy and neurons is yours (if you have any...).

A solution to what, all of my Macs running Yosemite run just fine, why would I fiddle with that?

Can we talk like grown people? If yes, I can explain to you.

3 - Yes, I can't. Because I went to the store, so obviously I don't have it.

5 - For example, here in my office I have 2 co-workers with 2 different Macs. 1 is a macbook pro 2011 (standard model) and the other is a macbook pro retina i7/16gb/ssd. The Retina Mac has a problem with the battery during only 2 - 4h while running Yosemite. The old and vastly used macbook pro 2011 doesn't have any kind of problem with battery.

This is considered and called BUG in the system. That's why you don't have the problem, my brother don't have the problem, 1 of my co-workers have the problem and the other co-worker DON'T (with an old machine, that could even have many cicles of battery to justify the problem).

Do you understand now? it's a bug, so it's a russian roulette. Is pretty much like the Flu! someone have, someone don't... but doesn't mean that it doesn't exist (because exist).

Held back on upgrading my MBP late-2013 to Yosemite. Did two weeks ago and had poor battery life -- it would run down relatively quickly, visibly quickly.

Fast forward few days ago, had issue with booting to black screen. Did the usual SMC, PRAM reset.. booted ok.

Lo-and-behold.. back to 11+ hour estimated battery life and far slower rundown. Again a big enough difference to be noticeable.

I have to qualify this that I only have 65 cycles and the capacity is 100% according to CoconutBattery (6313/6330). Also have to say I have not run it down to 10% so I cannot be sure if the % left exponentially decreases during full use.

I installed Yosemite yesterday and all went well for a little while. Then I tried to use my printer and...whoops! the little wheel just kept turning so I quit the printer. then the machine just lost a lot of power very quickly and it got very hot on the top right hand corner. I then uninstalled my printer and, bingo! The machine is now charging again although not as quickly as it used to I feel. please understand, I am NOT really computer literate so I may be just lucky; so far.

Danil@s,

Did a did a reset of pram and smc not do any good while in Yosemite?

What Apps were you most concerned to lose by upgrading to El Captan? I am concerned MS office 2011 will have problems in El Capitan (Excel mainly).

itsKeef,

Do you use Entourage in MS Office 2008? It seems for me this is what causes an occasional crash, but has not been too annoying. At least it Entourage, Excel and Word work on my Mini running El Cap. So it's acceptible for now...

Thanks for reply.

itsKeef,

Thanks for link to RoaringApps.com. Unfortunately, it is not very popular as it does not have many post and ratings at least for MS Office and Quicken for Mac. But I posted my experience of those apps to share with others.

If you use Entourage in Office 2008, I be very curious of your experience. Excel and Word (ver 12.3.6) work fine o far. Entourage (ver 12.2.4) crashes almost once per day. I do not use an exchange server. I just use Entourage to collect my personal Comcast and Go Daddy email account's mail to my Mac.

Thanks

Hello Joolsca50, I have had the same issue since my upgrade to Yosemite a year ago. I tried to upgrade to El Capitan this year, which fixed most of the problem, but not at all. 1 week ago I downgraded to Mavericks which is my original system and guess what? problem fixed!!! Which means, my mba DOESN'T had any kind of problem like Csound1 and other nonsense users told me in this thread. Just downgrade to Mavericks at least and test it out for yourself ! If you need any help, contact me. 🙂

Is this a 2013 MBA problem or Yosemite problem?

How does one know (or verify) that SMC has been reset successfully? It is impossible to simultaneously press and depress multiple keys, so I have alway held the meta keys down, then press and depress the "power" key. When nothing happens (the laptop doesn't turn on), I think it is successful, but I am never sure.

My 2 cents worth: I'm still on Mountain Lion with a bad battery, and I seem to run my battery down quicker while in sleep if I leave wireless on. I think it wakes up occasionally, spends energy scanning and scanning trying to find a known wireless network. It seems to use run down faster when no known networks are in range. To narrow down where power is being consumed, one may have to open up the laptop and take a time lapse infrared thermal image of the innards while it is sleeping.

Can be a battery problem too, but in most cases I'd say it was caused by the Firmware update that came with the Yosemite OS. This firmware continuous to be updated even if you downgrade or upgrade the OS over the older OS or doing a clean install to downgrade or upgrade. Anyway, Apple can't detect the cause of the problem, but I did a clean install of Mavericks and solved the problem for me (most of it, actually). That's the only fix I found out for me, at least...

I totally disagree with this description. It is wrong. People who can not get their Macs working correctly are not a good source of knowledge.

Thiago, tell us what is wrong with the firmware please. (We would be thrilled if you would share your knowledge, if not your solution with us)

Ok, let me try to explain what I'm talking about. I'm not being ironic or something, ok?. Have you ever heard about software bugs? I mean, errors\problems that a software can have? Problems that are not from the hardware itself ? This kind of problem that I had and many other people are still with, is a software problem, a software bug, which means that maybe happen with me, but maybe not with you (which is the case, because your battery is running fine). Of course, many people in this thread can have a hardware problem (battery), but I'm sure (because I've searched for months through the internet about it), that many people had this problem after the update to Yosemite. So, if I'm saying that the problem is the Yosemite, why wipe it out and install other versions couldn't solve the problem? Because along with the Yosemite OS update, came the Firmware update (pretty most like a BIOS on regular PCs). This Firmware, still attached to the Mac, even if you wipe out 100% of the system from the HD\SSD. Why installing the Mavericks with a clean install solves the problem? I don't know, Apple doesn't know either, but it worked for me, for a co-worker with a MBP (not a MBA like me) and for other people in many other foruns around the web. If you do not agree, that's fine, but the software battery problem, it's a fact and not just my "opinion".

There are 39 pages of complaints about battery issues for people upgrading and I can confirm as soon as I upgraded, I experienced this issue. Yosemite is working fine in all aspects except for battery drain which is sharp and noticeable. Apple intended for people to upgrade and intended it to be used on hardware they sold to consumers. The battery drains with no applications open, display dimmed. The day before upgrading, I had no issues with battery life at all. It is not the responsibility of average users to fix what obviously (to anyone not playing apologist), needs fixing. Or else they should inform people, as a caveat, that upgrading will significantly reduce battery life.

I thought perhaps El Capitan might be that fix.

When someone stabs you in the arm, you don't blame the blood streaming down on not being able to use your arm correctly.
