Maybe you could try calibrating your battery one or two more times and if it still doesnât work as well as it should, you could get the battery replaced. Appleâs after-sales service is excellent, you wonât face any issues with it
Hey, donât panic!
First of all, it shows 3 months because your Mac was manufactured 3 months ago.
About the capacity, well i wouldnât rely completely on a third party app like coconut battery. Its known to report incorrect readings sometimes. Check About this Mac->More info if you want to know how the battery is really doing.
Its normal for a new battery to take a little time to realise its full capacity. So make sure you follow the exact procedure to calibrate the battery as mentioned in the link below.
You can also try resetting your Macâs SMC as it controls some of the battery-management operations. Intel-based Macs: Resetting the System Management Controller (SMC)
The battery meter fluctuates in realtime according to the current usage. So if youâre doing an intensive task itâll show lower hours remaining as opposed to hours remaining in an idle state.
See, the battery life depends on what youâre doing, it will not always last 8-10 hours, it depends on several factors including the brightness levels and programs you are currently running etc.
Another important thing to consider when gauging battery life is Flash content. Flash, as we know, is a resource hog so if youâre doing anything Flash-enabled like Youtube etc., then you will see a drastic cut in battery life.
When Apple claims a â10-hour battery lifeâ, they get those results by doing âlightâ (not constantly opening and closing tabs) web browsing, excluding Flash, and running the screen a bit below the half-way mark for brightness.
Hope thatâs helpful.
Well, for the battery meter going haywire, it automatically calibrates itself while youâre working.. so for example, if your computer is idle, itâll show 8 hours.. if at any particular moment you are using up a lot of CPU, it shall show 2/3 hours (cause thats how long your batt will last in its âcurrentâ state i.e when youâre running something maxing out your CPU)
Also, the five hour batt thing.. Have you disabled bluetooth if you dont use it? Do you have automatic brightness on? Keyboard Backlight? With normal (Browsing/email/etcetera) usage, I get around 6-7 hours on my MBP, while if by any chance I do end up using Illustrator or PS while on Batt power iâll get around 4/5 hours. I did a marathon session of designing 8 A2 Posters (300dpi, which takes a lot of CPU power to render) on one charge of battery, lasted 4 hours IIRC.
So just keep using your MBP, calibrate it again as Pat/Styx said and youâll be as good as gold.
guys sorry for bumping the thread,but the battery really does seem on the decline,I updated the coconut battery app,and here are the new readings,the battery health is down to 96% now.
It seems like a steady decrease.
I did not re-caliberate the battery,the last time i caliberated the battery charge capacity went down along with the battery health,so i did not want to risk it.
I checked in the system profiler too and they report the same things as the coconut battery app.
Battery life is ok,im getting around 7hrs on wifi,with only chrome open with 10 tabs or so,with brightness at 25%.(Is that normal,i expected closer to the 9 hour mark)i have disabled ads,and flash content using extensions in google chrome(hoping for better battery life,of course ).
please do reply with your inputs,and please post some screenies of your macâs battery health if its convieninent to you,ofcourse
The thing is i really like this macbook pro(bah!,thats an understatement ),want to keep it in great condition.
Battery max charge down to above figure from 5623mA
About a couple of months back I had installed Coconut Battery and it indicated my battery capacity to be 97% and then it showed 96% within a couple of days. I calibrated the battery and it jumped to again 97% and its been at that mark ever since. I dont recommend you to recalibrate over and over again but do it once in a month or two.
My MBP runs most of the time off the power adapter, that could be a reason too. Run it off the battery only when needed or when calibrating.
