So I charged my battery to 100% and then unplugged it from the charger. Thats when the battery dipped to 97% instantaneously. It was very odd and somewhat scary. I just bought this MBP 2 days ago! Anything i might be missing? Is it supposed to do that?

Will fully charged battery on macbook stay charged overnight while computer is asleep?
View 4 Replies View RelatedI have a 5-year-old PowerBook G4. I remember I changed the battery about a year or two ago, because when I used to take it to classes in college, and use it unplugged, my laptop would shut off in less than an hour (more like ~30 min) when it reaches ~30%. After I got a new battery, it went back to normal, and lasted much longer. In the past couple of days, I noticed that within about 5-10 minutes of using my PB unplugged, battery goes from 100% --> ~85%, and then all of a sudden shuts down.
When I plug it back in to a power supply, and it starts back up, it starts recharging from 0%... this seems a little extreme. I haven't noticed this problem because I almost have it plugged in these days, as I usually use it at home or at work where I have a power supply available, and I use it for a few hour period at a time. Does this seem purely like a battery problem?! (ie. it's just time for a new battery...)
This never used to happen before. Only suddenly. Why is this happening? Is it something to worry about?

been using my mba for a few weeks now and i noticed that even when fully charged and still pulled into the charged the battery percentage still says 99% i have yet to see it reach and stay at 100% while being plugged in. is this normal? i am on my 5th cycle if that matters.
View 3 Replies View RelatedMy MacBook, "2 days old", from when I purchased it at the apple store says it is fully charged at 99% battery. I just re calibrated the battery last boot. Is this normal?

View 1 Replies View RelatedI would like to know the average battery life after each fully charged (especially when you just bought the unit).
I can only get 4:16hrs each time.
I've heard that if I don't disconnect the charger after my macbook is fully charged then the battery life and performance will get reduced and will be weaker.

When I bought the mac book pro I was impressed withthe 7 hours battery life, however I have found that when fully charged mine only has 3hours. Is this a fault or did I miss some kind of disclaimer?

"Does it harm the battery or reduce battery life, to use the AC adaptor for extended periods while the battery is fully charged?"Someone answered, "I would have to disagree with the others who say that it hurts your battery & reduces battery life by keeping your AC adapter plugged in with a full battery.I have done extensive research and asked many apple employees and have always come to the same conclusion. They all say to keep your laptop plugged into an power supply whenever possible. Only use your battery if you have to, in those times when you are not near a power supply.

I have a MacBook Pro. Keeps completely shutting down all the time when its fully charged and at random times when it is at 65% for example. Do I need to get a battery replacement? Or do I have a virus?

i've had my macbook for a little under a year and i think i may have shortened my battery power. i have a tendency to leave my laptop plugged in long past the fully charged time and allow it to run through the battery till it shuts down. i do this when i accidentally fall asleep listening to music or leave for work and forget it's on or plugged in. how hard on the battery or laptop is it to do this repeatedly? when it's fully charged it tells me i have roughly 4 hours of battery power available. is that the right amount? is there anything i should do to protect the battery? the manufacturer warranty will be up in march, should i take it in for a check up while i may have the option of not having to pay for it?
View 3 Replies View RelatedI have a new 13" MBP (1 week old), and the battery is supposed to be fully charged, according to the battery menu and some hardware monitor app. Well, the same menu says the battery is 95% charged, while the MBP is hooked to the home's sector. What the heck is that ? Last week, the information was consistent (100% recharged).
What is happening here ? Is the battery defective or is this normal ? I'm new to the laptop world, so I need to understand what is happening with the battery.
As soon as i remove mains cable from MBP the laptop just crashes no juice even though it says battery is fully charged. As soon as i replace cable, it reboots.i need this laptop to work on battery !!

Basically. I have my 15" saying that it is charged with the MagSafe light green. Although, the battery percentage is 96%. Ehh.. Is it supposed to be like that?
Like, not charge if it has only a little bit left to charge? Or is something wrong with my battery or MagSafe?
I have the impression that my MBP still charges when the power lead is hooked into my macbook. Is that true? Do i have to unplug the power cord each time my macbook is charged? Is there any way that the battery life might be affected?
I hope there is some sort of a circuit involved, that stops charging the battery when the battery is full, rather than overcharging it..
The icons says that the MBA is fully charged at 98%, it is not going further than that.

I bought a MacBook pro in march 2011 and has been working perfectly fine since then. The charger did break but I purchased a new one. I was using it for most of the day on Tuesday and it worked fine, I shut it down like normal and stored it in it's case overnight. On Wednesday morning I tried to switch it on and nothing happened! It's fully charged and I've tried the smc reset and nothing happens. There's no fan sounds or anything!

Had my MacBook Air for Christmas last year (2010), I've done the new update on it and now it won't turn on last night there was a world sign flashing when I turned it on instead of the apple sign.

MacBook Air, Mac OS X (10.7.4)
I am using Mac Pro with retina display
Processor : 2.5 GHz Intel Core i5
Memory: 4 GB 1600 MHz DDR3
Problem: My mac turns on only when connected to the charger even though it is 100% charged. Once it is on, I can disconnect the charger and continue to work on it.
However, if I don't connect the charger at the initial stage it does not turn on at all.

View 4 Replies View RelatedI picked up a pair of the apple batteries/charger for use with my magic mouse and wireless keyboard. I still had some juice in my current batteries so charged each set of two batteries for 24 hours and then put them in a drawer. Fast forward two weeks and my magic mouse has reliably run out of juice and when I put in two of the batteries, my mac states the charge at 74%. I've read in some of the other posts that because of the way NiMH and alkaline batteries differ, it is normal to have slightly lower ratings, but 74%?????
Most people reporting stated they got 85%, has anyone else gotten 74% on first run?
Are these batteries defective or is there something about my charging routine that caused them to be so much lower?
I just got my new Macbook Pro 15 (Mid 2010) laptop a few days ago, and i would just like to know if, when I charge my battery and it's fully charged, should I immediately unplug the power cord or can I leave it? What is the safest and best thing to do?
View 24 Replies View RelatedI 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?
