MacBook Air :: Loosing Battery - Woke Up To A Full Charge After An Hour Is Now At 53%
Mar 27, 2008
I have a Week 01 MacBook Air, and I just started to notice that my MBA has not been performing its best since I bought it.
This morning I at 0745am, but now its 0831 and my battery is now at 53%; is there something wrong? I took a stopwatch and averaged it at about 53-55 seconds where the battery will drop 1%.
According to coconut battery, current battery capacity is 4670 and original battery capacity is 5090, and the system profiler says that I'm at 31 charge cycles. And YES, i've reset the PRAM, PMU/SMC, and calibrated my battery

I've been a member here for a few years but mainly kept in the background reading about news and other interesting things like mods and discussions.
A few months back I bought a 15 inch 2.4 MBP, the most recent model as far as I'm aware, from the refurb store in the UK and after a few troublesome experiences ( they delivered an iPad to me the first time) I finally got my computer. Ever since, there have been a few problems.
First my Logic board died, handed it in and got it fixed.
Second the Keyboard backlighting wouldn't work, same thing, handed it in and got it fixed.
Now it seems that my MBP can't hold the battery charge when the computer is turned off, which to me seems very strange as it holds the charge perfectly well, 5+ hours although I've never timed it, during normal use.
I recently installed and mce optibay for extra storage since I don't really need the superdrive and it works great. Could this by any chance have anything to do with the drain?
So to summarize my MBp can't hold the charge when computer is turned off but works fine when its on. I have an extra HDD installed where the superdrive used to be via mce optibay and everything else works fine.

After all is said and done, and heavy Macbook Air use, there is only one thing still bugging me. Its not the slightly uneven lighting, not the 3 hours charge nor the 3:30 battery life I get constantly, nor the 6200 RPM fan. When I charge to 100% and let it sleep for 12 hours, I lose about 20% of the charge. Yesterday I was at around 25% and when I opened it this evening, 24hrs later, there was nothing left. If I leave the macbook air closed, I think that the battery would reach 0% after 3 days. This is not normal and some kind of leak.

So I usually keep my UMBP plugged in at all times. It unplugged by accident and went to 99% so I left it unplugged but literally less then maybe 7 minutes my battery is already reading down to 92%. Brightness on screen is set all the way up, if that has anything to do with it.

I haven't been able to find out an answer for this. I bought a MB467LL/A model Macbook (2.4ghz previous unibody version that became the Macbook pro). Local store had them on closeout and it was a hot deal. Anyway, it was brand new and had a 0% battery when I brought it home. It's been about 12 hours and still isn't quite charged fully. Almost though.
Is this normal for a brand new battery? I can't imagine it usually takes 12 hours to fully charge the battery. I've never had a computer ship with a dead battery before so I'm wondering if it was bad or simply that's how they come now a days.

I received my new 15", i7, 128gb ssd, 8gb ram macbook pro on april 19th. I love it and have no problems. Have any of you guys noticed that the full charge battery capacity, which is found under system profiler-power, varies often. When I first got the macbook pro the full charge capacity of the battery was around 6830. Now with each charge it seems to go down slowly. At first it jumped from 6800 to 6600 and now stays at around 6520. Is this normal?

"To allow the adapter to recharge the battery to 100%, simply allow the charge to drop below 93%. The adapter will automatically recharge the battery to 100%."

I have a week old 11.6" MacBook Air. The battery has 3 cycles. However, using Coconut battery the battery capacity is showing 96% fully charged. Would that be unusual after 3 cycles?

Late 2008 refurb Macbook Pro, 2.53ghz, Windows 7 RC (therefore forced to use the 9600 at all times). According to this report, the MBP got around 3&1/2hrs of run time with a dimmed screen and watching videos. From a full charge, I start browsing the internet (no videos at all), and my battery reading read as follows
91% 1hr, 16mins
90% 1hr, 20mins
89% 1hr, 24mins
87% 1hr, 23mins
Not only were the readings all over the place, but even from a full near charge I wasn't even getting an estimate of 2hrs, while Apple advertised 4 for the late 2008 model, and the review I linked to says they got 3&1/2. Do I have a bad battery, or does simply running the 9600 reduce the battery life by such a drastic amount? I have already calibrated my battery following the guide on the Apple website.

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.

Then I can reboot work for half an hour until battery is like 50% then it shuts off again... then I can reboot again and work for some more time. I've checked with coconut battery and when the computer stops at 70% I still have like 1700 mAh...I've reset PRAM, power management, etc...
Of course my battery is old, but it should work until 00%... not stop at 70%. Before I spend like 100$ (that is what a macbook pro battery costs here in Mexico) I'm willing to try anything...

I bought a 3rd party battery for my MBP. I put it in and after cycling the battery i noticed that the full charge capacity was only 3990mAh (supposed to be 5500mAh). I returned the battery today and got and an upgraded replacement. this shows the full charge capacity at 4995mAh (supposed to be 5600mAh).
is this normal. Do I just need to give it some time or is it something with the batteries.

Why is my Mac not at 100% battery after having it powered off and plugged in charging all night? As long as my charger is plugged in shouldn't it be at 100%? I never unplug it. It shows it is charging but stays at a constant 98%.

Basically I'm having issues with my newly acquired Powerbook G4. When i bought it the battery was not working at all so have now installed a new replacememnnt battery which works fine but having some slight issues. So...
First time I charged it, it reached 100% but green light never came on to indicate full charge. When I run the PB off the battery it gets to 20% and it shuts down without any warning it's low on battery (trying to switch it on after this is impossible, it clearly has no life) After the above I connect the power lead and start up the computer, the battery indicator starts charging from 20% onwards. Something fishy definitely going on and I have no idea what it could be, I calibrated the battery but it has always cut off at 20% since first charge/discharge.

I have a 1.67 GHz Powerbook G4. This morning it was fine. When I got home from work, it decided that it suddenly no longer wants to stay on when not plugged in. The battery is showing a full charge. The light on the plug is green. But the second I unplug the cord from the laptop, the entire thing shuts down.

Just bought a new 15 inch retina MBP. My question is...should I immediately charge the battery or let it run to zero first and then charge it? Does it even matter?

All I was doing was watching Brothers & Sisters on ABC's web site... So, yes, I was using the wi-fi. I had screen brightness dimmed to about 50%, and I turned the backlight off on the keyboard... So is 1 hour normal?
I noticed the fan was running the whole time. I didn't realize watching a video online would cause the processor to heat up so much!!
I checked the CPU utilization, and definitely Safari was cranking it up there...

I know that the 13" MacBook Pro supposedly gets '7-hour battery' life, but does it really? If any of you have the 13" MBP, how much battery life do you get with yours?

My new MBP has 5 hours of battery when doing light web browsing at medium brightness. Only 2-3 hours when playing low res youtube clips, and 6:45 hours with all apps and wifi turned off and screen brightness at minimum.
When I first turned on the MBP I charged it to 100% and then discharged it down to 0. Is this battery life normal? What happened to 8-9 hours with wifi and web browsing? I can't even get 7 hours with everything off!

So from what I understand my 2 month old MBP is supposed to have a 10 hour battery which is a stretch! I would say 5 hour battery at best, which is great and I am not complaining but 10 hour eh? Is that while the computer is sleeping?

I calibrated my battery for the first time since Dec. When I plugged it in this morning, it took 3 hours to charge all the way, and now it's stuck on 99% full, 0:00 till completely charged, and I'm getting an error when I click on the battery in the menu bar that says "Service Battery". When I click on the error, it tells me that it may not be functioning properly and to take it to an authorized apple service retailer. Before I waste 2 hours by going to the Apple store and back, has anyone else had this problem, and is there a way to fix it without having it looked at?

If you look at apple's battery life page it states the MBA battery is removable, I thought it wasn't supposed to be?Battery Lifespan For Apple notebooks with removable batteries ? such as the MacBook, MacBook Air, and 15-inch MacBook Pro ? a properly maintained battery is designed to retain up to 80% of its original capacity at 300 full charge and discharge cycles. You may choose to replace your battery when it no longer holds sufficient charge to meet your needs.

purchased a macbook Unibody back in October 2008 when they were released and use it heavily. The battery no longer holds a nice long charge - I get about 2 to 2.5 hours out of a full charge.
The battery has 149 cycles on it, which is obviously high (and correct, I use the hell out of it). With it still being in warranty, is it worth pursuing a replacement battery? Will Apple tell me to go take a hike with the high cycle counts?

been using my older MBP with windows 7 for a while and have never notice oddies with the battery until now. Then recently after replacing the failed HD and re-installing Snow Leopard on my 2007 MBP, the battery panel is telling me "Service Battery"; it's battery health according to coconutBattery is fair for it's age (50%).
the unit (battery) has been replaced previously due to being considered 'under performing'. Is Snow Leopard trying to encurate it's users to replace the battery more frequently? If not, does anyone know why this appears? I'm at lost, since it appears to work fine, if not charging completely.
