MacBook Pro :: Battery Time Remaining Indicator Works Wrong ?
Oct 28, 2010
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've had my unibody 2.0 since November. It's always said 5 hours or so when i open it up fully charged. This week it's started fluctuating wildy. While typing this post it's gone from 3 hours 23 mins to 4 hours and five mins....it started at 2 hours....now it's up to 4...very odd. Any ideas on why this has started happening all of the sudden?
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 have an early 2008 non-unibody MacBook Pro. For about a year now, the status of the battery has been "replace soon." I was still getting a pretty good amount of time off of one charge so I wasn't too worried. This past Saturday morning, I woke up, checked the battery indicator lights on my computer (it had been sleeping since the day before) and it said it had about 60% percent so I opened it. I was on the Internet for about 10 minutes before it shut off without warning.
It wouldn't turn back on when I pressed the power button, so I plugged it in and it turned back on. When I checked, the battery status was "replace now." After using it, I turned it back off and left for NYC for the weekend and didn't bring it with me. When I got home last night, I plugged it in and tried turning it on with no luck. The battery indicator light was flashing one light, so I just assumed it would need to charge for a bit before it would turn back on. After about two hours, when I went to bed, it still was flashing just one light. I kept it plugged in over night, and this morning when I checked it, the battery indicator lights showed that it was fully charged, but it still wouldn't turn on. I still kept it plugged in throughout the day just in case, but it still won't turn on even though all the lights are lit. Is the battery just showing me false information, or should I be worried about more than just the battery?
I'm not sure if this is SL related, but I get the service battery warning when I click on the battery status. iStat reports it at 62% health. Rev B 1.6 just 6months old. Should I bring it to apple or is it just a bug of SL?
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.
Purchased this notebook used, but very nicely cared for, excellent condition. I ran the Apple Hardware Test and everything passed including the logic board.
The battery has 500+cycles. The problem is laptop shuts down at 50% or less of battery. Clock is wrong at startup but is correct a few seconds later.
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.
I recently had issues regarding my display (June 2009 MBP 17") not dimming as the ambient lighting changed. The issue was only recent. I reset the SMC, and that has appeared to fix it.
However, I've noticed that the battery indicator lights do not fade after 5 seconds anymore and just turn straight off when the computer is open and on. When shut down or asleep, they behave as normal.
I reset the SMC again to ty and fix this but there was no change.
Now, I could be wrong, and maybe that's how it always was, but I do remember them fading no matter whether the computer was active or off.
Can anyone confirm this and if so, provide any possible fixes?
It's not a huge issue, just a minor annoyance now that I'm aware of it.
My MacBook (purchased late 2007) battery indicator has an "x" where the battery meter usually shows the time/% remaining. When I unplugged the power cord, the computer shuts down. The battery life indicator on the bottom of the battery shows it's fully charged and it works fine with my other MacBook. How to resolve the battery issue?
anybody else have this problem? just got it in the mail today, everything is perfect except that the lights on the left side are not working. i don't know if there is a setting i have to turn on or something.
Over the last few weeks my battery health on my late '07 MBP has declined from about 79% to a terrible 39% this morning. However, just a few minutes ago something very strange happened. The charge indicator jumped from 23% to 51%, but the indicator remained red. I did a search but didn't find anything about this issue, so I thought I'd post. Has anyone seen this before?
I just calibrated my battery 2 days ago and it still showed my health as 39%, but now iStat is showing the battery health as 70%. The battery info is listed below:

I've already tried the "remove the battery and hold the power button down, then put the battery back in, etc." thing. Not working. My MacBook keeps saying my battery is not charging. If I press the button on my battery, all five green indicator lights come on, as if the battery is fully charged. When unplug the MacBook's power cord, the computer goes dead. This is a 2.4 Penryn black MacBook.
For the past few days, my mid 2012 15" rMBP has been powering down or sleeping while in the middle of performing tasks, and more importantly when it's ABOVE 15% charge. Just today however, I now have a red battery indication at 52% and holding.
At the time, I had an external monitor plugged into the thunderbolt port closest to the ac adaptor port. I was running Adobe Lightroom and Photoshop, but nothing else, and was not connected to the internet. I had turned wifi off. My problems continued until I plugged in. Once on a full charge, I unplugged and the same thing happened all over. Numerous times. So, I disconnected the external monitor, and thought that solved my problem. The next time I used the computer, I put the external monitor into the other TB port and did not have any issues, however I wasn't using the rMBP as extensively.
Today, again while performing tasks such as importing/exporting images with LR & PS, my laptop shut itself down. It runs warm, and fans are purring like crazy, but that's normal for the work I'm doing. Prior to the shut down, the battery read ~24%. I plugged in and woke it up. No external monitor is attached today. I am not running any other programs besides Chrome at the moment. I noticed a red battery light at 52% and it has not changed. Option clicking the indicator shows a "normal" condition.
I have had a Speck hard shell case covering the laptop for a few weeks, but no issues until this week.I am a pro photographer who shoots tethered on location and carries my rMBP around on assignment. It has never been dropped, or damaged in any way.

Alright so i've had this Macbook pro for quite a while now, its the February 2008 version. About a few days ago it said "Service Battery" on the top right. I bought the 3 year coverage for the Macbook pro.. would it cover the battery being replaced or no? When i read service battery it says the battery isn't functioning normally - it doesn't say replace son or replace now, so im assuming theres something defective with the battery?
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 wife's Macbook 2.1 is acting strangely. The Battery indicator led's are full (green) the charger led is also green and the software shows 100% battery is charged. After a couple of seconds after disconnecting the charger it switches off. I've tried resetting the SMC and this allowed a full nights use without the charger but on the next day it went back to only holding for a couple of seconds. I don't want to have to reset the SMC every day. It's running on 10.5.8 and is all up to date.
Info: MacBook, Mac OS X (10.5.8), 2GHZ Intel Core 2 Duo 3GB SDRAM
When I plug in my MacBook Air (2011), when the battery indicator hits about 50% all of a sudden it jumps up to 100%. Then, when I unplug the power cord, after a few minutes it drops back down to 50%.
My macbook pro 13" Mid 2010 model will simply not turn on! I tried does SMC and PRAM but still no results. The Macbook gives me 3 green blinking lights on the battery indicator and nothing else. I already tried switching the ram for a dead or faulty ram but still nothing. Also the power adapter doesn't seem to want to work. When I plug it to the macbook, I can hear small sparks each time, looking at it, there are some black marks on both the charger and the mac. [URL]s
i bought a new macbook pro last week and suddenly the battery isn't charging. I had it plugged in earlier today and i worked then i unplugged it and now it won't work. i changed the adapter from the extension to the regular and i changed power outlets.
I don't know if anybody else experiences this problem, but when I open my laptop (from sleep) and then try to find a network via the airport icon in the menubar it won't find anything until the battery life indicator is done "calculating". Sometimes that is around 10 seconds... I don't see how they are related, but it always works out that way for me. As soon as it's done calculating the remaining battery time I can click on the airport icon and it will find a network within a few seconds. Otherwise it just sits there searching and won't find anything...
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?
calibrating my battery for the first time this morning. i just opened my macbook pro to see that the time left icon jumps every minute. it goes from 8:50 to 12:38 to 6:54 to 11:37 to 7:40! and now it went from 8:45 to 9:19! the percentage remaining is consistent and correct but the time left is way out of whack! sorry for the slang! now it went from 9:19 to 9:11 then 8:47. i have the screen at the lowest brightness, no backlit keyboard, nothing else running except firefox. i wasnt aware that i was supposed to calibrate my battery and its been about 3 months since i bought this. now its at 8:37 now 8:18. this is quite
I haven't used my macbook for a couple of months...was working fine the last time I used it. now I've plugged it in and my battery indicator says "not charging". the comp goes off the second i take out the charger, so the battery is at 0%. What do I do? I bought it in 2010, so I no longer have that 1 year warranty.
