MacBook Pro :: Should I Trust My Batteries "time Remaining"?
Nov 11, 2010
So im a new mac user and had a question about battery life. i did all the things apple says to insure a longer life such as calibration of the battery, using it at half brightness, turning off blue tooth, half volume etc. but i notice that when i plug out my charger it will estimate time remaining as 8 hours or so but like 2 minute later it will go down to 6 hours and fluctuate between 5-8 throughout the time using it. what gives?

I've just got myself a nice new Mac Pro and am really surprised to find that it is more different to Windows than I was expecting. I feel like a toddler trying to learn a new language to do all the things I am used to doing on Windows.
Quite often I just Google my Q's....or search on YouTube, and usually get the answers quickly.
I can't seem to find a specific answer for this Q though.....
On Windows, whenever you downloaded something, you were given a % telling you how much had been downloaded and how much was left still. It also gave you the progress in gb / kb.Surely there must be a way of having this info show whenever I download something ? I really do not want to go to the App Store and start buying things.

Just got my new macbook pro 13 and have gone through messes with some of the system preferences and am downloaing some stuff. I dunno whether if is affecting it but my estimated battery life says 2 hours and is around 90% now. I did fully charge it and have some other stuff on the background so. Also, I've read that people have it charged for maximum battery life so. If you can charge it, do it or if its around 60% or something it should be charged?

My battery for my 12" Powerbook G4 is munted and i need a new one. There are a few around for about $90AUD from 3rd party re-sellers which is less than half the $200AUD apple want for a genuine battery.
So i'm just wondering, has anyone got any recommendations about 3rd party batteries? i know it will probably vary a bit depending on where they're from, but i spose i'm just wondering if its worth the extra $100?

I am new (sort of) to owning a Mac, I bought my macbook pro a couple days ago, so far I havent used it much for other than surfing the net. My question is regarding the Battery time remaining indicator, first of all it changes alot, so i never truly know how much time I have left. Is this normal? It can say anywhere from 3-6 hours left when I am at 90% battery. Usually at 90% battery it says I have about 4.5 - 5 hour left. I thought I was supposed to get up to ten hours of battery? The percent indicator seems to go down fairly fast like 1% every few minutes. Is this Normal? Should I take my macbook over to the apple store to be checked out?

The battery indicator on the top menu bar on my other MBP's gives 3 selectable options for display: Icon Only, Percentage, and Time Remaining. My new MBP retina only has 'Icon' and 'Percentage'. You can still see time remaining by clicking on the battery icon manually.
Applecare said "they must have removed it for that new version of the MBP, you could always try reinstalling the O/S from scratch just to be sure".
Under Energy Saver the only option is to 'show battery status' on the top bar.

I have a Rev A 1.6/80.
Just running on battery, the estimated time remaining is normal. About 4:00 with a 97% charge.
But when I have it plugged in, it goes really low. About 20-14 minutes. I know I have an almost full charge and the battery isn't shot or anything because I just used it for about 3 hours yesterday without plugging in. Even with the innacurate estimate it still reports the % correctly.
The iStat widget reports similar numbers, but not exactly the same. 16 on it, as opposed to 13 in the menu bar.

I just bought a used iBook G4 1.33GHz on eBay from a seller that offers a 30 day return policy. It came today and upon boot i don't get the classic "boot sound," but instead a somewhat garbled burping-like sound.
However, the iBook seems to function fine otherwise. It's a bit slow and "hesitant" running Leopard, but it's running the stock 512MB of memory so I'd expect that from it until I stick a 1GB stick in there. Also, the regular speakers work fine once the computer is booted up, so I'm guessing the "boot sound" plays on something analogous to a PC Speaker in a non-Mac PC.
The casing looks good and no defects on the screen, the bottom does get pretty hot, but I think that's usual behavior from a G4 iBook, right?
So, what does everyone think? I'm hesitant to make a stink over the stupid "boot sound" speaker, particularly since it might be easy enough to replace (and it's supposed to still be under AppleCare anyway, so it may just be a trip to the local Apple store to get a fix anyway.

I downloaded the Pollux app ([URL]) and loved it. It worked really well during the trial and I want to buy it. However, I'm very paranoid using my credit card over the internet. Have any of you purchased this app and are the developers trustworthy?

I am using 3.0.10 with Leopard 10.5.7. The way the older versions of Firefox worked was if you saved a password to the keychain and then return to the webesite at some future time, it would automatically display the user ID and PW in the login fields of the site.
But now I find you have to type the first character of the user ID in order for it to display the rest of it. I find that a pain in the neck. Can anyone tell me how to get it to work the old way? Either with terminal or an add-on I can trust? If I am not mistaken, there is a way to enter an area in FF that displays a long list of unix defaults that you can change.

The remaining battery indicator (top right) is not completely accurate. The measurement (time) constantly varies.
As far as I know a 13" MacBook Pro should have 10 hours battery time. In this case the reading constantly changes from about 8:52 hours then back to 9:12 hours, 9:34, and other readings, etc.
Is this normal?

I frequently encounter this totally blocking problem when attempting to authorize changes to Certificate Trust Settings.
This occurs when A dialog is presented when app such as Mail encounters a certificate whose identity is unknown.You choose to show details and select the option to "Always trust (server) when connecting to…"Click ConnectA System authorization dialog appears and immediately hangsin Activity Monitor, "SecurityAgent" is shown as not responding.
At this point there is no legitimate way to shut down or restart the Mac other than forcing a power down, since (presumably) SecurityAgent is involved in the normal shutdown process.
After restarting, when the process happens again, I am able to successfully authorize the certificate. It only occurs if the computer has been up and running for a while (hours? days?)

My white MacBook Intel Core 2 Duo is not charging the battery anymore. It says "No Batteries Available" and it works only with the cable plugged in. I already tried the following:
- buy new battery - FAIL
- reset SMC (30 seconds procedure) - FAIL
- reset SMC (5 seconds procedure) - FAIL
I brought the Mac at the Apple Genius. They say there has been a liquid leak and asked me $780.00 for the repair (it does not make sense to pay this amount for this computer). I am not aware of any liquid leak. Yes, I had my MacBook in my backpack during rainy days but I had an umbrella. Anyway, I would like to have any advice about (i) where I could bring my Mac to repair (I live in the Bay Area) or (ii) what I could try to replace, following tutorials (like the very good ones on ifixit site).

I have an early 2011 Macbook Pro 13 it was working OK but now has come up no batteries detected and I have tried a pram reset, smc reset and a new battery but still no luck. I did manage to get it to work for a while by turning it on with the power adapter connect then restarting it but at the point of the restart I pulled the power and it came on with the battery.
If I start it with the power adapter connected and then pull the power it will boot to the login screen briefly then go into sleep until I reconnect the power. When the power adapter is connected it just has a solid green light at all times never changes even if I do the smc reset.

My macbook is a week and a day old. It is the newer whitebook with nvidia and all that. Coconut battery says its 123 months old? why is this? The only thing i can think of is that apple possibly had a used macbook come in and they switched out some parts and changed it to the new one? btw it was bought new at best buy.

I think built in batteries are a good idea , but having to give your computer to apple and pay 200.00 after your battery dies is not.
how have your built in battery experiences been?
do they last long as stated 7 hours?
not sure if i want to make the switch , i like my removable battery.

My MBP 15" Hi-Res Glossy i7 is on the way (ordered on 19th) and I was just wondering how the batteries on these machines were doing. I've seen a lot of feedbacks from great (8~9 hrs) to average (4~6 hrs) to bad (2~3 hrs). So how is it that these reports are varying so much? Is it possible for numerous defects to be out in the world right now?

I've got the dreaded "No batteries available" at the top of my taskbar. The Power Source says: Battery. I have my laptop plugged & it is showing a green light. What is a simple way that I can fix this problem? I can't go to a Genius Bar because the closest Apple Store is over 120 miles away. The battery is a little over 2 years old

Why has Apple not recalled the batteries in the white macbooks(early 2009) when it is very evident that these batteries have a manufacturing fault? Mine has swollen after 112 recharges but should have lasted 300 recharges before only having 80% capacity after which it will still work, just not as many hours. Because of the excessive cost of Apple batteries and Apple's releuctance to recall defective products my next laptop will be a windows8 machine.

I have a Late 2006 MBP (This one).
I don't use it much (it's for travelling).
I leave it plugged into the wall or unplugged for weeks at a time without using the battery. Since I bought it, I have gone through 4 batteries, including the one that came with the machine. That's over $500 in batteries!
The computer says "Batteries not Charging" with an X in front of the battery icon. Or it says "No batteries available".
I'm about to buy my 5th battery. What should I do this time to prevent it from dying like the others? Or is it a problem with my computer, and not the battery?

Can anyone assist me in find the promotional video that Apple did when it went to non-removable batteries? I would like to find it in a high quality format. I need it for a school presentation. I've found it on YouTube, but the quality is not that great.

i'm sure there are many people who use spare batteries like me. but how do you manage them though? i find it very annoying having to charge them one by one. charging 1 battery takes a few hours, which is almost fine. but when you have a spare battery, it takes twice as much longer to charge them both. not fun. a separate battery charger will help greatly reducing charging time

As you can see from the info at the bottom of the post, I own the 2008 model. Now, with my hardware slowly becoming obsolete and the wear starting to show its effects, I would have to get a new laptop in the near future. However, as I discovered, all new models have batteries that cannot be removed. After 2 years of service my battery swelled and had to be replaced. That's 2 years. With a new battery, my laptop's life has been prolonged.
How long will a new laptop last? Will I really have to buy a brand new expensive computer every two years just because of a design flaw?

So I went down to the local Apple store to have a gander at the new iMacs the other day. Think I'm going to get one.
The weird thing is that I opened up Terminal on one and had look at mach_kernel in the / directory, expecting to see two kernel architectures, x86_64 and i386. Lo and behold, there was a third one; architecture ppc.
