MacBook :: Poor Wi-Fi Performance When Using Battery?
Aug 15, 2009
I have a MacBook (late 2007) and I've noticed that my internet crawls when I'm using the laptops battery power. I can be downloading a file at 200 kB/s under A/C power, and as soon as it goes on to the battery it'll drop to 10 kB/s. I'm assuming some kind of power saving is being activated, but this has only happened recently. Around the same time this started happening, I updated my computer to 10.5.8 and I also turned in my computer to the Apple store to have the palm rests replaced for having cracked under the weight of the lcd. Would this problem be caused by either the update or the repair, and if not, what could be causing it?
Apple Macbook Air late 2010, has been giving me poor battery performance even after replacing the battery under warranty. I am unable to find a solution, even the local apple service provider seems confused. Should I go for a replacement?My Macbook Air runs on the OSX 10.7.3 with all updates as on date. I use only softwares such as Microsoft Office for mac, Safari, Mail, iChat, iTunes regularly.
i bought an ssd for my laptop knowing that is not going to use the sata3 because this model is only sata2 capable but the you check in system information and says that: Velocidad de enlace: 3 gigabitsVelocidad de enlace negociada:1,5 gigabits There is any possibility to use the sata2 speed in this laptop, because the ssd is going faster than the traditional hdd 5400rpm but not as fast as other ssd in sata2. with TRIM active the maximum performance is 130 read and 90 write while with the hdd was 70 read and 70 write. Versión de la ROM de arranque: MBP71.0039.B0EVersión SMC (sistema):1.62f6 Tried with a bootcamp and windows 7 64 bit and the same performance.

I have a broken fan in my 2008 MBP. The broken fan is on the side where my right hand is so im assuming thats thr right fan on the MBP. It still spins a bit but is insanely loud but my MBP performance has dropped considerably lately and im wondering if there is any correlation between the two. The main issue is video.
Videos that used to stream fine low lag and are choppy and working in Final Cut and After Effects has become quite the slow and verrrrrry choppy process. All things were working out smoothly until recently. I am getting the fan replaced next week and hope it remedies these problems. If anyone has any experience with this I would love to hear it!
I recently upgraded my 1st Gen MBP 2.14Ghz and my legs no longer get cooked while doing basic task. This is a great improvement.My new laptop is the 2.53Ghz w/ 4GB and 9400M Nvidia GPU w/ 256MB shared memory. upgraded w/ EFI 1.7
Aside from the upcoming Snow Leopard, the main reason I upgraded was because I watch alot of online video. Netflix, Hulu, etc...I have read that the new GPU does alot of the decoding which keeps the CPU in single digits.I noticed something was sluggish the first time I started watching videos. Netflix had a vertical sync issue that I never experienced w/ my old MBP.Then today I was watching Hulu and I saw the processing or CPU jump to 112% and the base of my laptop was very hot.
Like I said I purchased the new MBP hoping to avoid cooking the family jewels. Anyone know what's going on and what I can do to stop this?
I know this has been asked many times before but seeing as im a new mac user ill ask anyways. I bought my Macbook pro 13" i5 yesterday and have noticed the very poor battery life. A partial reason i bought a mac was because of the long battery life advertised. My battery is lasting 3 hours off charge ( the same as my 3 year old eePc) I have called support but unfortunately being a Sunday no one is available to chat. Lets see my chances on here.What can I do to make my battery life last longer than 3 hours!?It the battery drains even when im just browsing the net with no other applications open... as im writing this it has already drained from 59%-50% within a 10 minute time span..
I just bought a 13" MBP over the weekend as an upgrade to my original series white Macbook bought July 2006.My understanding is that the battery is rated for 7-8hours. Yet I do not see any improvement over my previous 3yr old Macbook regarding battery life.Right now, I have the screen set on dimest, nothing else running other than the browser, battery is at 80% and it says 4 hours remaining. What gives?I have had this Macbook and my old white macbook sitting next to each other doing pretty much the same thing and the % battery remaining seemed to track pretty close between them. The new Macbook doing better, but not by much.I used migration assistant to copy over the system. But I've done a new install since then. Could it somehow remember the old Macbook's battery performance?
So I've had my MBP 13 for 3 weeks and i took a screenshot of coconut battery. I've noticed crappy battery life so does the 94% mean my battery isn't doing as good as it should be? Shouldn't it be at 100 since its new?
I used my 13.3/1.86/4GB MBA to watch football today and was pretty surprised with the poor battery results. Would this seem normal?
Took off charger at 11:45AM CST, battery 100%Apps open - Mail, Chrome, Parallels with Win XP running, no XP apps open11:45-12:00pm - Simple browsing, no flash running (I use FlashBlock)12:00pm - I start up one window for NFL Sunday Ticket Online, Flash fullscreen video and one window for my Yahoo Fantasy Sports which also uses Flash. For the bulk of the time the NFL game is on fullscreen video with my Fantasy app running in the background1:15pm - I notice my battery is down to 48% with approx 1 hr 10 min remaining. I check my screen brightness and it is at 100% (not sure why), I reduce brightness to 50%1:15 - I use the computer same as at 12:00pm but now at 50% brightness 2:20 - My computer goes into hibernation (there was a low battery warning about 5-10 mins earlier.
So I essentially got 2 1/2 hours of usage with the bulk being heavy usage with flash. For the bulk of the time the computer was using 50-60% of the processor and the exhaust was about 3400rpm (the fan was audible but not loud). Does this usage time seem normal for what I did? I would have expected at least to get 4-5 hours with a 13.3 using flash. Also I was surprised that the battery life didn't improve at all after dropping screen brightness from 100% to 50%.
I can't seem to get 3 hours of life out of this battery and I wanted to know if I was alone on this. I've drained it multiple times and my capacity is at 4829. Sure, with the screen dimmed all the way and everything turned off I can reach 4 hours, but that's not why I purchased this machine. With my screen on max, no bluetooth, and WiFi on, I struggle to get 3 hours. This is with normal web-browsing, typing in word, etc. Forget about watching a movie, because the time remaining will just drop like a rock. I don't recall what the max capacity was on these batteries. If it's 5200, then I'm already at ~93%. At what point do I go into Apple to demand a new one?
I've been getting poor battery life on my MBP for about a month now. I get like 90 minutes to 2 hours max with brightness down and bluetooth off. I tried calibrating to no avail, and finally I'd had enough and called Apple.
I still have 8 months left on my original warranty. The guy on the phone told me that unless I bought Apple Care for the extended phone support, he could not help me. So I said fine, should I just go into the Apple Store? He said no, they would refer me back to him and he still couldn't help me. So I asked him if my one year warranty included battery problems like I'd outlined, and he said yes, but that I'd need phone support. WTF?
Okay, that makes zero sense and I'm annoyed now with his endless loop of nothing. Basically I can't get a part of my purchase that's covered under warranty taken care of because I haven't bought Apple Care yet? That's ridiculous. Has anyone else heard of this? Of course, I always buy Apple Care for my products, but when I purchase it varies within the first year based on when I have the money.I made a Genius Bar appointment, but I was really hoping to not have to go there today. Just wondering if anyone has some insight on this.
I have a 13 month old macbook pro. Recently it has been operating VERY sluggishly. Its slow/jumpy when scrolling through internet pages, through documents, pictures, downloads etc. The little rainbow 'loading' icon (i'm sorry i'm not sure what it's called) seems to appear all the time, when doing most things.I've also noticed that my battery life has gone appaling. I charge it up and get a couple of hours tops now and the 'time remaining' icon jumps up and down massively now rather than remaining relatively constant.
I recently got a 13.3 with 4 gigs of ram, and lemme preface this by saying that it is a phenomenal computer. I have an ipad, and using airdisplay to do wireless dual monitors is a sight to behold.
However, I've noticed a rather disturbing battery drain on my MBA. It came at about 86% charged, and after a full charge I've noticed fairly significant battery drain. I didn't time anything, but it hit ~50% battery after an evening of really sparse usage (brightness 50%, wifi on, no mp3s playing, click2flash installed and no flash content used).
I figured it was first day jitters and recharged it to full, then watched a single video on hulu with flash enabled and full screened at the same 50% brightness with 80% sound. After a 3 minute video, I was already down to 97%. Then I searched online for average battery life, finding out that it was capable of handling 11.2 hours of light browsing usage from anandtech. This took a max of an additional 10 minutes, which dropped the battery to 95% (no flash was on and hulu was closed). I shut the lid and opened it again this morning after 8 hours of standby and it was at 94%.
I don't feel very confident that this MBA can last half the day if I was using it non stop, let alone a full 11.2 hours. I want to know if this is a battery defect on my own laptop and warrants a replacement, or if this is the status quo.
In fact, in the time it took me to type this post on my desktop computer, my macbook air has dropped down another % to 93% with absolutely nothing running and no active use.
After the install of snow leopard, and a full charge. My battery at 96% showed only 2:45 hours, over the past 30 minutes with little no usage n the laptop (other than letting it sit at the office and periodically checking battery) I am seeing 81% charge and 2:05 on the charge.
The screen is dimmed, display sleep is set to 5 mins, computer sleep to 15....
i remember in Leopard you were able to select different profiles in the battery menu on the menubar. There was an option for high performace and power saver, etc. In snow leopard this is not an option, is there anyway I can bring those settings back? Or is snow leopard automatically adjusting processor power?
Just wondering what the norm is in terms of where my battery levels should be. When I first received my MBA 2 weeks ago, the full charge mAh capacity was around 7100. Now after 6 cycles, the full charge max mAh is 6678.
Is this normal for the max to drop so much after only 6 cycles? Just wondering what others are experiencing in terms of battery performance.
I just switched my old 120Gb drive with a 320gb one (FUJITSU MJA2320BH G2 -- speed should be the same as my old one), and I'm noticing a drop in battery performance of about 20%. Is this just a coincidence?
I'm having what I'd consider poor performance on the new 2ghz Mini in XP.I get non-responsiveness when moving large files across the network and it just is slow overall.Its slower than my previous 1.8ghz Mini.
The standard MS drivers for the SATA controller are installed even though I ran the Bootcamp install, does anyone else show the Nvidia SATA controller driver installed? That is usually the biggest cause on non-Intel chipsets, the default MS driver for the SATA controller...I was just going to install Forceware and see what happens but wondered what other people show in Device Manager.I get a lack of response from Remote Desktop, and after several hours of high network traffic it just stops responding to the network period.OSx I'm not sure about because I rarely use it but I did boot it up to do some surfing in Safari and found its response time to be slow.
I just ordered my first mac a few days ago online, and seeing that almost everyone takes advantage of the suposed 10h battery of the 13', I wonder if it gets slower when you are using the battery.
my current notebook (compal FL90) is considerably (much) slower when it is not powered to the grid especially if I'm running photoshop for casual editing.
increasing the amount of RAM in a MacBook Pro (latest model unibody 15" i7 processor). If I increase the amount of RAM in this laptop from 4Gb to16 Gb, should that in and of itself result in a decrease in battery performance? This is assuming no increase in number of active programs, etc. A friend of mine was told by an Apple employee that just increasing the total RAM in a laptop would result in the battery draining more quickly. I am no computer genius, but that does not sound right to me? After all, why should the battery work harder if the excess RAM is not being used at the time.
What effect will the macbook have, if i fully charge and discharge the battery on a daily basis. I will leave it running on battery power when i leave for the day, and let the battery drain/discharge fully through the night.I will hook it back up in the morning to have it fully charged, may be 30 - 60 mins after it being fully charged, i will pull the power out and run the laptop the whole day on battery.
I know that Flash uses more battery power. However is that only when you are actually using a window that needs Flash. Does just installing it decrease your battery performance in any way? I am running into lots of sites that require Flash and I would like to install it but not at the risk of severely limiting my battery usage when not actually using it.
I am not sure if it only my macbook, but I notice a slight performance drop when I run on the battery v the AC. I notice that my application load slower, folders open slower and expose and spaces response is also slow as well.
I am planning to buy a new 13" MBP but I am kind of concerned on the battery performance. Specs: a) 2.26 GHz CPU b) Upgrade RAM to 4GB c) Upgrade HD to 500GB 5400 WD d) Brightness at 70% / with keyboard backlight / Bluetooth OFF
Questions: (Can you give me an estimate on the following) 1) How long will the battery last if I play Facebook games nonstop (poker / mafia wars / cafe world / etc.) 2) How long will the battery last if I play Sims3 nonstop? 3) How long will the battery last if I watch a DVD movie nonstop? (from the drive) 4) How long will the battery last if I type documents nonstop? BTW, can this MBP 13" play sims3 in the default normal settings?
Point 4. Says the computer will automatically go to sleep and then point 5. Says I should turn of the computer. Isn't it the same of the computer stays in the sleep mode?

Earlier today, maybe around 3PM, I was using my laptop, and it was charging and it was maybe around 60% battety life when out of no where it just shut off and even the light on my charger went out. When I turned it back on, the fan was running and there was an X over the battery icon. I've tried turning it off and on, and leaving it alone for a few hours, to see if it would resolve the problem but it didn't. It is currently 9:52PM, I'm still experiencing these problems and I'm using the exact laptop to type this, but I don't know how much battery life is left.
Running MacBook ProMacBookPro4,1Intel Core 2 Duo2.4 GHzW882458RYJZos x 10.6.8 Im running differnt language My battery is pretty much dead is that the problem?
Planning on Purchasing one of the New Aluminum MacBook Pro's. I would like to know what are the best ways to have your battery last longer and hold the normal charge? Also on the Battery Section on [URL] it says it not good to have your computer charging all the time but then people on the forums say it's better to keep it plugged in! What is it? What should I do? Listen to Forum users or Apple). Also what is a good setting for the Screen Lightiness? Is HalfWay see able? What about 75 percent notches. Will lowering the battery brightness save battery?
I've been looking for some info on the older 2007 MacBook Pro battery specs and stats, etc., but have been somewhat unsuccessful. Lately my MBP has been draining the battery at a much quicker pace than normal. This machine is only a year old now (however CoconutBattery says the battery is 16 months old). Still, the battery capacity shouldn't have diminished too significantly. Before I restored the Mac and installed the Windows 7 Beta, I could average 3-4 hours on a full charge. Normally, I would keep WiFi + Bluetooth enabled, an external monitor attached, several USB peripherals plugged in, and the main display would be set to maximum brightness. 3-4 hours was pretty nice considering the amount of power the machine could have been using.
After I partitioned my hard drive, the battery life was cut in half on the OS X side. Windows 7 power management was even worse. I figured that there may have been extra disk activity causing this problem. After I finished toying with Redmond's new OS, I removed the Windows partition and moved on from there. I know after I removed the partition, I was getting excellent battery life initially. Once that short period ended, it went downhill from there. The battery meter has become surprisingly accurate as of late; in a minute or so, you can easily watch the percentages drop 1-2%, which appears abnormal. I can manage 3 hours on a single charge at best, but I usually get less. I decided to take greater care in cycling the battery, in hopes of nursing it back to health, so to speak. It doesn't appear to be working so well. Enabling WiFi and other peripherals only drains more power, but turning them off again adds only 5 minutes. So when I'm using several devices at once, I'm lucky to get a little over 2 hours. Turning off menu items and background apps does nothing either.
It's been this way for several weeks now, and yet, iStat, System Profiler, and CoconutBattery all report seemingly acceptable and consistent battery info: 86% Battery health, around 180 charge cycles, and the capacity is around 4700mAh (out of the original 5500) for now. The computer believes all is well. Performance says otherwise. I'd like to think that physically the battery seems to be okay. I've cycled and calibrated it several times. I have read reviews that indicate that Santa Rosa MacBooks with new batteries have averaged similar runtimes to the ones I experience now, but I know mine has usually bested all of the reported tests. It just seems wrong for the average runtime to go from almost 4 hours to 2 when the battery is (supposed to be) maintaining the same health level. I have AppleCare if it needs to be replaced, since this drastic change in usage time is very noticeable and counterproductive for me, but it could just be the computer (or me for that matter). Is this behavior normal for a battery of this age? What should I look into? If this is normal behavior I can live with it, but I would prefer to get as much out of the one I have.
