How long does your battery last? Mine is UNDERPERFORMING

I have a new Macbook pro running lion - and Im a new Mac user. Im just wondering if something is wrong with my battery. I keep reading Im supposed to get 7 hours of battery life but Im getting much less than that...and all Im usually doing is itunes or the internet.


Ive been logging the time and the percentages and they dont add up to 7 hours or any where near it. The battery has been fully charged...and it was run down to zero. But as you can see by the time/percentages, it is not giving me anywhere near 7 hours. If a 90% charge is only 4 and a half hours, and 70% is only 2 hours or 50% is only an hour - there's no where near 7 hours. In fact, this evening Ive been on for about three hours and Im almost down to zero. This doesnt seem like it should be happening on a brand new Macbook Pro thats a month old. Is it not really a 7 hour battery or should I get it checked out - or do I need to adjust some sort of setting or system preference?



91% 4:28

73%- 2:14

53% -1:06

29%=1:11

MacBook Pro, Mac OS X (10.7)

Hi s,


The times/percentages are usually not very accurate. I you want to know exactly how long it runs, you have to actually time it.


Remember you have 90 days of free AppleCare phone support, a 14 day return/exchange period, and a one year hardware warranty. Why not give them a call and see what they say?

Get it checked mine lasts like a good 6 and a half hours. 6 or 6.5 I would be happy with because the 7 hours is always without wifi and bluetooth and all of this extra stuff that uses energy. But what your describing isn't good. If you are just using it normally then it should last way longer then that. Oh! Idea! Did you leave it plugged in to the wall alot even when its charged? That will damage your battery but I wouldn't expect it to happen as quickly as in a month.

Weird cuz Ive gotten conflicting information. Some people have told me what you said - dont leave it plugged in if youre working from home becuase it will harm your battery, and others have told me the exact opposite...leave it plugged in when you can cuz it will save the battery and make it last longer. Then I read the Apple batterycare that the other poster linked to and that kinda said a bit of both - it just said that you should let it run down once a month - and Ive definitely been letting it run down multiple times per week.


Im just so tired (as a new Mac user) of problem after problem after problem. Ive had such a bad Apple experience with the store techs and Applecare...Theyve always given me wrong information, ruined my computer, made me be in store 4x in the first 2 months for at least 5-8 hours EACH TIME for them to try to fix and redo things. I finally ended up meeting with the store senior manager for 2 hours to explain all the horrors Id been through and he of course apologized and couldnt believe what I had gone through and what his employees along with Apple phone support had said and done...Then he gave me a new laptop to start over and had an employee manually transfer every file so having problems now on the NEW laptop is making me even more frustrated. ( I know Apple just won best support again but Ive had the opposite experience...everything that could go wrong has...no one even believes my horror stories...I even had an employee email me profanities...just another day at the office I guess - sometimes you become too popular for your own good...plus theyve admitted the mac is getting short shrifted with all the ipad/iphone hysteria)...Well I digress.


I guess Ill call Applecare and then t heyll tell me to take it into the store and the whole horrific process will begin again. I did time it tonight and it was no where near 7 hours...It was close to 3 hours and all I had open was itunes and Safari...and Ive already dimmed the screen. So NOT GOOD for a new laptop.


I also read to click the battery icon and hit option - and it says my battery is 'normal' for whatever thats worth.


Someone told me if you use desktop wallpapers that may eat up battery. Someone sent me wallpapers and showed me how you can set system preferences to randomly rotate them and Im wondering if thats using up a lot of power. I wouldnt think it is but its the only thing I can think of. But tonight def. 3 hours.


UGH


I literally have had more problems with a Mac than with the 10 year old PC desktop it replaced..and that was nearly on its death door - and yet the mac has caused more problems than that did in ALL TEN YEARS
