Apple :: Macbook Nonremovable Battery And Battery Wear
Jun 12, 2009
I am looking into getting one of the new macbook pro's. Though I must say the non removable battery does concern me a bit. In past laptops I have had, I without a doubt saw increased battery wear and tear when I left the batter in the laptop while the laptop itself was plugged in. I completly destroyed a battery on my Dell laptop by doing this for about a month when it was asking as a desktop. I took the laptop which used to get around 4 hrs of battery life and then after a month it got no more than 15 minutes.
So after that I always took the battery out, so now with the new macbook pro's you cannot take the batteries out, so wont the batteries wear down to nothing faster than if you took them out when not using them?
I got my hp dv6 last Monday, so it's quite new. About three days ago I downloaded System Information for Windows trying to find out which was my GPU temp(what I didn't find, it only shows only HDD and CPU temp) and looking other stuff I noticed that my battery wear off was 7% while the battery is(was?) also new, so it got me preoccupied, so I checked it again yesterday and it was 9%!, I checked today and it's at 10% . Just c'mon I don't dedicate all my free time to plug and unplug the battery ,so why the fcuk(note there's no grammatical error) it wears off so quickly,
Just a heads up to all the studio XPS owners. I opened up HWmonitor to check some temps and I noted the battery wear level and its 23%! I have only had the laptop since mid February and its degraded this bad very quickly. Needless to say I will be calling Dell and getting a replacement.
But I thought I would bring it to the attention of the community, because its been so helpful for me I try to give back.
I bought my Dell Inspiron 1545 about 6 days ago, I decided to install windows XP and drop vista in-order to save the battery life from vista hungry resources but
it didn't go very well i get about 2.15 hours max (with only firefox running and a LAN connection cable plus i shutdown wireless+bluetooth).
from the battery under windows XP, then i read about vista/windows 7 that they have better power management than the ancient XP so i installed the vista basic that came with the laptop but when i measure the battery's wear level which was too late i found out this:
I have a utility reccommended here called BatteryBar. It has a category called Battery wear. What is battery wear? Is it as it sounds, a degradation of the maximum potential of a battery over time? Is there particular actions that cause an increase in battery wear?
I have a 1 week old Acer 1810T. Up until now the battery wear has been 0.0%. However, I let the battery run down to the point that the computer shutdown. I thought this was a good thing. I know in the old days batteries would develop a memory. They recommended a occasion full run down and charge. I think I read this is not true for the Lithium battery, however.
Well, after restarting my computer I see my battery wear is now at 1.4%. Is this because I let it run down? Also, if I want to my battery to last as long as it can, is it better to take it out when using it at home on AC power? That is about 90% of my usage.
Does anybody else with a dv5t have excessive battery wear? I purchased the laptop in August of 2008. According to hwmonitor my battery can only hold 30758 mwh down from the designed capacity of 47520 mwh. I rarely used the battery. Maybe once a week for 5 minutes to move the laptop.
I asked a friend with a dv5t purchased around the same time and his capacity is down to nearly 27000 mwh. Our laptops are the same except his has the intel integrated graphics while i got the 9600m gt. Also he uses the battery almost daily.
When i first got the laptop i got nearly 2 hours out of it. Now i can barely get an hour.
We both calibrated our batteries a few times by fully discharging and fully charging a few times which did nothing.
I know that batteries experience wear but does this seem excessive? I believe the estimate is about 10% a year. But this is almost 50% wear in a year and a half.
I have a Pavilion dv6345us that I got back in June 2007 and I like the notebook but one of the main problems is that it keeps messing up the batteries.
The battery it came with ended up dying completely (doesn't hold a charge) within a year or so. Then I bought a 12-cell battery off eBay (generic brand) last summer/fall and now that battery too is almost completely dead.
I don't know if its a problem with the laptop or the battery so I don't know what to do. One thing I do notice is that the computer heats up a lot frequently so maybe that is the reason for the battery wear?
Only thing I have done to the computer is upgrade to 2GB RAM from the 1GB RAM it came with, a month after I bought it.
I bought this laptop 5 months ago and I have been monitoring it slowly deteriorating by battery life, it is a 6 cell 4400mAh battery and I use it every day, and make sure not to let it drop below 10% battery power as to not do full discharges and only partial.
I was getting 1hr 50 mins when I first got the laptop which may have been max or min settings I cant remember but anyways which seems not as good as the advertised 2.5 hr battery but I can understand that advertised and actual may differ and max, min would have had an effect. Anyways now after 5 months (Purchased early december) I am only getting 58 mins on full charge at minimum settings, now this does seem quite ridiculous and NHC is reporting 49% wear level.
My question is, is this normal for a Li-Ion Acer battery after 5 months, it seems quite bad to me, and all I can think is the laptop was left on the shelf for a while before i bought it, or that it is defective. I rang acer warranty support and I feel quite fobbed off with them saying this is normal and usage patterns and that their warranty for batteries only last 6 months and I should expect only to get 1/4 of the full charge i did when i purchased after 6 months. So acer is in the business of making low quality batteries?
my Sony Vaio FE690 only lasts around 30 min on battery (I tried calibrating, still same life) but every utility that I try (Battery Eater, Notebook control, Everest, etc.) reports a wear level of 0% and a full charge capacity that is the same as the original capacity.
Can anyone confirm that the Sony battery firmware does not report the wear level? I'm wondering if it has something to do with my BIOS upgrade.
I'm not even coming close to this with my 2010 macbook pro 13 inch unless I turn my brightness down to 50%, on reboot it defaults to 100%. This is when doing nothing or just surfing the net. I can get about 7 hrs, with my laptop screen turned to 50%. Any tweaks available? I'd love to know how Apple came up with 10 hrs.
I use my macbook a lot lately without connecting it to a power outlet. I disconnect it from power supple in the morning and put it in my backpack, and after 3 hours I waked it up by opening the lid and I notice the battery is at 95%. The battery is pretty much out of power after about 4 hours of use with airport on for wireless connection, and at the lowest brightness. Is it possible there is a battery leak, or is this normal? The battery is at 99% health and 40 cycles. It was went down to 96% health before, and it came back to 99% after I calibrated the battery.
I have a Macbook Pro I bought in summer 2007, and I'm have concerns about its battery life, and so I was wondering if anyone could help me please.
I hardly ever use my laptop away from my desk, so it's plugged in all the time. While plugged in, I still keep the battery in the laptop. It's only been through 10 cycles in 2 years, and I know I should've calibrated it monthly, but I didn't and I really wish I had now. Right now, when unplugged, my battery only lasts about half an hour. I downloaded coconutBattery and apparently, my original battery capacity was 5600 mAh, and now it's only 543 mAh.
My question is, did I mess up the battery myself by not calibrating it, or was the battery defective in the first place? :S Or is it just old?
I'm a real n00b when it comes to computers....but if this ISN'T my fault, the laptop is under an Apple Care Protection Plan, and so would that cover the battery? Is there any way to fix it without getting a new battery?
I bought a new white macbook a few days ago. I just noticed now the batter meter says "not charging" and its only at 95%. Is there something wrong with my battery? should I drain it all the way and then recharge?
i've just purchased a 2.0GHZ aluminum macbook recently and am having a small problem with it. The macbooks battery percentage indicator seems to be dropping a percentage point every couple of days even though i'm on mains power? The power adaptor LED is green idicating the computer is fully charged. I've calibrated the battery as apple recommended but its still doing it. The apple tech guy said that it is possibly a 'power board' problem rather than a battery fault and it will need changing. Has anybody else experienced this problem? Other than this small problem the macbook is fantastic, should have coverted over from a pc years ago
As a new 13" Macbook Pro owner, I am wondering if upgrading with non-Apple certified HDD and RAM components could drastically effect the battery life.
I am told that there is firmware in the HDD of the one that comes with a Macbook that is necessary for maximum battery life. From comparing two HDD's in my Macbook (one certified and one not) I think this might be the case. What is your experience?
Also, does there exist Apple certified RAM and, if so, does it offer more battery life compared to non-certified?
I have just bought my Unibody Macbook. I haven't received it yet, but I was wondering if anyone has any tips on undervolting, buying a different battery, etc. to get more battery life on it. I really need it for school and I don't always like sitting next to the plug in a classroom.
I had a MacBook unibody for about a week while I installed Bootcamp XP/etc on it for my daughter - then I shipped it to her. I would like to get one for myself later this year, funds permitting. However, I have seen comments in several posts about potential problems with the battery cover. Does the battery cover have a design weakness or is it just really tricky to re-attach to the system?
if there is an alternative to macbook batterys, meaning ones not made by apple and therefore cheaper. Also, i have not heard very good things about aple batteries, mainly that they just die out, is there any true to that?
I've always been a Mac fan and am quite impressed with today's update. I recently purchased 2 new 13" Macbook's a few months ago for my mother and myself. The only complaint we both have is the horrible 2.3-3 hour battery life, instead of selling our lovely investments do you think we can pay to have the new built-in battery placed into the system or should we sell and repurchase? I understand the new systems have quite a few new hardware updates but that's all irrelevant, we just want that new sleek battery life!
We also want the new iPhone 3GS. Grr Apple, you always know how to do it right.
I've been working with the new MacBook Pro for two weeks and I've found the battery life impressive. It let me work the whole morning (around five hours with a couple of ten minutes breaks, with wireless and half bright). I'd like to maintain this performance as longer as possible,
1. When I get back home I usually plug in the laptop to electricity to recharge the battery while I keep working in the afternoon for several hours, should I unplug it when the battery is full? Is a good thing to keep the laptop always plugged in?
My second question has to do with the fact that I'm a bit distracted, then,
2. Does this laptop have any way to let me know that there are, for instance, only ten minutes left before it go to sleep? (an acustic signal, a warning...)
