WTF, 3 hours of Battery life for 2010 MacBook Pro?

[InfoSecmgr]

Apple says otherwise..
http://docs.info.apple.com/article.html?path=Mac/10.5/en/9036.html

Considering that is from the 10.5 help section....it doesn't help much in this case considering it was written when 10.5 came out, 2007. Hardware has changed since then. If you want to contribute then I'd suggest posting relevant articles on current tech. And, I wasn't stating that the new MBP's had the smart charging tech as a matter of fact, it was a genuine question.

The steps in battery calibration haven't changed. They're identical to those posted by tool80, so the post IS relevant. I'd suggest doing some reading and learning before attacking those who are trying to help.

Mac OS X 10.6 Help

Calibrating a portable computer battery

Calibrating your battery ensures you get the longest possible running time from it. Calibrate your battery during the first week you own it, and then recalibrate it every two months. If you use your computer infrequently, it’s best to recalibrate it at least once a month.

Whenever you purchase new batteries, calibrate them as well.

To calibrate a portable computer battery:

1. Plug in the MagSafe Power Adapter and fully charge the battery.
   
   When the battery is fully charged, the light on the MagSafe Power Adapter connector changes to green and the Battery icon in the menu bar indicates that the battery is charged.
   
   
2. Allow the battery to rest in the fully charged state for two hours or longer.
   
   You can use your computer during this time as long as the power adapter is plugged in.
   
   
3. With the computer still on, disconnect the power adapter and continue to use your computer.
   
   
4. When you see the low battery warning, save your work and close all applications. Keep your computer turned on until it goes to sleep.
   
   
5. After your computer goes to sleep, turn it off or allow it to sleep for five hours or longer.
   
   
6. Connect the power adapter and leave it connected until the battery is fully charged.
   
   You can use your computer during this time.

Completely deplete it until Mac wont turn on and then charge for 12 hours.

Also when you will contact apple they will tell you that those numbers 8-10 hours only white using Apple Software (e.g iTunes, Safari etc). Also note that if you are using flash that will kill your battery superfast, most of the time it loads cpu up to the max.

Where did you come up with that? That's not recommended anywhere by Apple.

Same problem, its BS. I can watch about 30 minutes of streaming video and my battery drops from 96% (max charge) down to below 50%. And my MBP is only a little over a month old. The main reason I switched from PC to Mac was for the battery life. I feel ripped off.

Did you read the thread? Did you read the FAQ in post #14?

 

[HLdan]

I don't know why people (yes including me) are still posting on this thread. The OP never came back (and who cares at this point) and he was extremely rude to people here anyway.

You're right. It's ridiculous how people come here asking for help, then display a rude attitude toward the very people who try to help. I'm not worried about the OP anymore. There are others asking questions (and some posting misinformation) in the thread that I'm responding to.

Yes to both. I feel ripped off, should have read the small print first, never would have bought this.

No computer maker promises the same battery life to every user, regardless of what they have running. That's why understanding how they arrive at their estimated battery life is important.

From: http://www.apple.com/macbookpro/features.html

The longest-lasting Mac notebook battery ever.
The new energy-efficient architecture in every MacBook Pro, along with automatic graphics switching in the 15- and 17-inch models, gives you dramatically longer battery life. On a single charge, the battery in the new 13-inch MacBook Pro lasts up to 10 hours (8 to 9 hours on the 15- and 17-inch MacBook Pro).1

1. 13-inch MacBook Pro testing conducted by Apple in March 2010 using a preproduction 2.66GHz Intel Core 2 Duo-based MacBook Pro units. 15-inch MacBook Pro testing conducted by Apple in March 2010 using preproduction 2.66GHz Intel Core i7-based MacBook Pro units. 17-inch MacBook Pro testing conducted by Apple in March 2010 using preproduction 2.53GHz Intel Core 2 Duo-based MacBook Pro units. Battery life depends on configuration and use. See www.apple.com/batteries for more information. The wireless productivity test measures battery life by wirelessly browsing various websites and editing text in a word processor document with display brightness set to the middle setting.

Youtube, XXX you stuff and websites with a lot of flash stuff will drain your battery really quickly. Turn off wifi and plug in ethernet and you will see good battery life.

Connected to wlan now, having 10 tabs open, screen at maximum, 92% battery left -> 6hrs and 7 mins remaining.

With brightness at 40% and only 1-2 tabs open I can surf for 8-9 hours.

 

[stefan1975]

well i am not expecting miracles and know the 8-9 hours on my base i5 mbp15 are difficult to achieve.

however why does my battery never indicate it has a remaining time of >6 hours, with 2 cycles and health at 100%?

i am not expecting 8 hours but the indicator never says i would get anything above 7, even with BT off, no flash, brightness at 1/3 it says 6:15 after a full recharge.

i calibrated it twice, hence my two full cycles.

am i missing something here?

At the apple store, because I came to them with the same problem. It helped me.

If your "streaming video" is Flash, then you just found out why there is no Flash on the iPod Touch / iPhone / iPad. Open "Activity Monitor" and check your CPU usage.
