I have noticed that over the past few weeks, my battery continues to fluctuate between 43% health (Replace Soon) and 95% health (Normal).The weird part is that, when the battery is listed as 95% health, it functions normally (2 hours of charge). However, when the battery is listed as 43% health, it lasts significantly less even when doing the same light web browsing.
View 2 RepliesI got myself a Macbook a couple of days ago. It's also the first Mac I've ever used, so I'm not fully acquainted with all the OS characteristics. In particular I'm puzzled as far as the battery monitor is concerned: the time it shows keeps on fluctuating: as I'm speaking it first shows 3:02, then 3:11, then 2:52, then again 3:00, then 2:43 and then again 3:02 (all these values in less than, say, 5 minutes).
View 3 Replies View RelatedThe battery time on my Macbook Pro 15" goes from one time to another in a matter of minutes. I fully charged the battery after it had been drained. This is what I mean by fluctuating:
11:23am-11:28am (5m)
7h51m, 5h54m, 6h57m, 6h16m, 5h29m, 6h38m, 5h53m, 6h29m, 6h9m, 6h13m
11:29-11:34 (5m)
6h39m, 6h36m, 6h4m, 6h8m, 6h49m, 5h52m, 6h30m, 6h0m, 5h43m, 6h30m
Apple states that it should get 8-9 hours on a full charge and mine gets 6h15m. It's only 10mos old.
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?

I routinely put my Macbook to sleep with a full-charge at night, then unplug it (the power cord doesn't reach where I keep my computer at night). When I wake it up, it generally has 93% of a charge left. This has never happened and I am wondering if it is time to replace the battery.

How long can a battery actually last ?

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 just got my first 13' MacBook Pro 1 week ago and a couple of days I ran a cross a thread about how to look up your battery condition and most peoples said their Battery Condition was "Good" but mine is showing "Normal" and I just got it a week ago. My question is, is this really normal or should it say Good?
View 2 Replies View RelatedAfter about two hours my battery on my 13" mbp is at 35% from 100%.
All i did was some web browsing and about half an hour of video chatting on ichat. My brightness is at halfway.
is this normal drain? the specs say 10 hours, but when i first got it it lived for about 6 hours, which was plenty for me.
i've noticed recently that my battery has been acting funny, i'm thinking it may be because of my heavy audio work with garage band and reason.
the app coconut battery says my battery capacity is at 94% so I'm not sure what the problem is.
I've had this laptop for about 3 months, and i've properly calibrated it twice.
After how many charging cycles do I need to replace the battery?

Are you all experiencing about the same battery time as me?
People I know with a 2010 13" MBP doing about the same activities as me are experiencing much longer battery time, around 7 hours.
I was looking into buying a new macbook pro and I was just looking at my current macbook 13 inch and I hadn't checked my battery health for a while so I went and had a look. I was extremely suprised to see my battery had done 1046 cycles and according to istat, my battery was at 92% health...
I have had my macbook 13 inch since november 2007. It has been having a few problems lately with over heating but I was wondering if it was normal to have a battery that had gone through so many cycles and still have around 4-5 hours battery life (when I am just browsing the net and doing uni work i.e not watching movies or listening to music)
battery shows 4 cycles and @ 95% - normal? Last night it was 97%.
View 10 Replies View RelatedI've had my refurb rev a for a week now. I absolutely love the form factor and it has really impressed me with what it can do. (My last computer was the 1.67 Powerbook G4 with 1 gig of ram.) However the battery life concerns me. When I got the air it had 4 cycles and 97% health. 10 days later i have 15 cycles and 93% health. I'm not concerned about the cycles, but should the health be declining this fast? If not what can I do to increase it? I've tried calibrating it and it really didn't change anything.
View 3 Replies View RelatedI just noticed my mbp battery was at Great but since its been dieing alot faster lately, I decided to take a look. First thing I noticed that it now says normal? Is it because im on reserve battery? Im just worried because I cant just go out and "buy" a new battery.
View 4 Replies View RelatedI have a 15 inch June 2009 MacBook Pro that has 7 hour battery built in. I only had it for 2 weeks and I only have 3 cycles on the battery. My question is that why under System Profiler, it told me that the battery condition is normal? Where my other 13" MBP that my brother owns for about a month is showing Good.
i tried calibrating it, and it still shows Normal. Coconut battery says I have 100% battery health. But still, it's kinda annoying for me.
Is my battery defective or is that normal. My battery is at 32 cycle count, 5 month old and 96% according to coconut
It's the new MBP "13
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!
I just calibrate my battery and full charge my mac and I got 5:26 of battery life... is this normal for an i5 15"?

According to the coconutbattery app, my laptop's battery temperature is usually around 87ºF. I got worried when I checked my sister's macbook pro and noticed that her battery temperature is around 25ºF (with the same app). I put a fan next to my laptop for an hour and the battery only cooled down to 85ºF. The temperature stays the same regardless of it being plugged in to the charger or not. Is it normal for my battery to constantly be this hot? I play computer games fairly regularly, but even when I have no applications open the battery is still hot. I am currently running Snow Leopard 10.6.8. I don't want to upgrade to Lion at the moment.I have already tried resetting the SMC, and nothing happened.
