MBP 2009 - upgraded to lion diminished battery life

I upgraded my MacBook Pro July 2009 from snow leopard to lion. My computer's battery life has now halved. What am I able to do? Can I also just uninstall Lion and reinstall Snow Leopard?

yes, as long as you have the install disc for Snow Leopard.

Upgrade results in diminished battery life

you recently upgraded software on my phone and my wife's phone. Since that time the phone gets very hot and the battery life has been cut in half. I read your response to another unhappy user in which he was told to go to the Verizon store. I did that and was told that I could either upgrade my phone or try a hard reset which would wipe out my data and my apps. This is obviously a problem with the upgrade, since I am not the only one having this problem. I would expect a patch to be sent out immediately to fix the problem.

Been suffering long enough after the KitKat upgrade. Figured it was time to post.
1). Phone runs hot - my theory is that it's struggling to find/keep LTE and cycling too much on the network
2). Battery life is horrible now. Used to end the day after normal use at 45% remaining, now recharging by mid-day
3). Text messages sometimes take up to 10 minutes to send
4). Random slowdowns - too many to really list, one app or another will freeze, not connect. I realize this can be an app issue, but still - a real drag.
Will not do a hard reset - I would rather pay out my contract and go to another carrier, seriously. Battery usage shows that Android System is taking up most of the juice - 24% usually. The phone worked great at one point, now it's junk.
For real, do I have to go to a Windows phone? Is that the life lesson here?

Does chargeing overnight diminish battery life?

I charge my iPad 2 overnight every few days when the battery dies and I notice the battery doesnt stay on 100% as long as it does when I unplug it after it completes a charge, but i notice when I charge over night it stays on a certain percent for a long time unlike when i unplug it right away. It's the same thing with my iPhone 4s. Does this diminish battery life? Or does it do nothing and it's all in my head?

I charge my iPad battery every single night and I did the same thing with my first iPad - the original model iPad which still gets about 10 hours a day out of a full charge. You are not diminishing the battery life.
You can read Apple's information about the iPad battery.

MBP 13" Aug09, lost 2 hours battery life after upgrading to SL

Hi, my Macbook Pro bought on Aug 09 lost 2 hours of battery life after an upgrade from Leopard to Snow Leopard.
I brought it to the Apple service center where they checked the battery and they said that the battery has no problem.
Then, they suggest me to format my mac and reinstall Snow Leopard on a clean disk which i did without any success.
So now, my battery still hold 100% of it's original capacity (over 5450mAh) but my battery died before 3 hours with 0 program running !? (it used to last over 5.5 hours while running Leopard)
What's the matter with my battery.
And of course, i tried all the calibration before i post this topic.
If anyone can help now, it would be so great ! can't expect anything from Apple as they consider my battery as new.
Thanks !

I too have been experiencing worse battery life.
I used to have about 3.5 hours on my now one year old Unibody MBP.
After SL (and switch from original 5400rpm to seagate momentus 7200rpm) I'm now down at about 2 hours.
Wifi enabled
Bluetooth enabled
Brightness around 80%
2 hours is very little compared to the promised 5 hours.
My battery stats:
Health: 94%
Cycles: 112
Full charge: 4344mAh
Feels like I'm on an old lousy PC laptop again.

Mountain Lion Drops Battery Life and Freezes Often, Mountain Lion Drops Battery Life and Freezes Often, Mountain Lion Drops Battery Life and Freezes Often

I use MacBook Pro 13", 2011 edition. Since I installed Mountain Lion, my MBP's battery life drop from 7+ hours to roughly 5 hours overnight. Worse still, it freezes about once a day. Does anybody else experience this? Got tips to troubleshoot these issues?

I initially had similar issues with Mountain Lion, however I thought it was isolated to my configuration. I did make some adjustments using the command line power management tool and the difference are night and day. I never thought it amy have been a change in Mountain Lion. In any case, given the prevalence of this, I created a blog listing the changes I made and explaining it for those with increased interest.

Diminished battery life since 10.6.5 update

I updated my computer with the OS X 10.6.5 update when it came out a week or two ago and since the update, my battery life has gotten incredibly short compared to what it used to be. Normally, without having Airport on, just using Microsoft word, I would easily get 7 hours of battery life. Since the update, with 100% battery I'm getting 3.5 hours at the most and it's down to 75% within 20 to 30 minutes. Oh and I've had the computer for about 3 months. Battery health is already down to 92%
I'm beginning to think I just got a buggy computer because I've been having trackpad issues, and my USB ports don't recognize printers, no matter what I do.
Any idea's on my battery problem? I have searched and searched the internet and have found nothing so it may be an isolated issue.

This sounds exactly like what My 13 inch (mid-2010) MBP is doing.
From day one (about 4 months ago), the battery showed that it was down to 92% with coconut battery? I've never gotten over about 6 hours of battery life; after this latest update to .5, I'm lucky if I get 3.5 hours of battery life.
I've checked the activity monitor and nothing is running the CPU excessively, except when I'm watching something in flash, but even if I block all flash, I still get the same battery life. Also, it's always warm on the bottom (even with flash blocked) and the fan runs all the time, too.
I'm not doing anything differently than I did before the update - just have chrome open all the time.
I swear apple is getting lazy with everything software related lately.

X201 Upgrade to 8GB = Kill Battery Life

I upgraded my x201 to 8GB of RAM from 4 GB (2x2GB) and it knocked my battery life down by about 2 hours. Has anyone else had this same issue? I can't believe that going to two 4GB DIMMs from two 2GB dimms would reduce battery life by that much, so I'm wondering if there is a way to reduce the battery power draw or anything else?

try to remove the memory stick you added, then check if issue stills persists. if the battery life doesn't change after removing it, it's not because of the ram stick.

After upgrading to ios6, my battery life is cut in half.

Battery life has been cut in half after upgrading. Sometimes, when taking phone out of the case, it's very hot & the battery is almost gone even though it hasn't been used since charging.

I would have to agree. I think that the update is affecting some users. I am guessing you are using a touch. I boutght mine a year ago, it had i4 on it, after the update to i5 i noticed a vast improvment on the battery life. After the update to i5 (which igmackenzie) has nothing to do with how you updated it, wi-fi or hard wired, as long as it takes you are good. It does seem that for some reason, i5 has a finiky issue when it comes to correctly updated apps (i5 ready) and the app store crashing. (have updated about 75% of mine and the issue seems to have resovlved its-self.)
As a long time user of this site for issues i am having and a long time mac user, will you please keep your opinions out of it. this is a help site, for people to remedy issues. NOT a blog for user forum. Appleinsider has a great place for you to discuss your OPINIONS, as for your HELPFUL advice, that is greatly appreciated. But it does appear that the user basically figured it out on their own.

Anyone experiencing diminished battery life and delayed response times with iOS 5 on iPad 1?

Since installing iOS 5 on my iTouch and iPad, the battery life of both devices has been terrible! Before I could get 1-1/2 or more days use, now I'm down to hours without using the device. . .and I've turned off all of the locations services except, find my phone. Next, I'm going to try turning off the auto time zone setting.
I've also noticed diminished response on my iPad when opening Settings, Notes, etc. --like 10+ second delay before anything happens. I'm really considering restoring my devices back to the older OS.

Downgrading the iOS is not supported. My iPad is a bit slower that it used to be, but I havn't noticed any change in battery life.
In terms of response times you could try closing all your apps completely and then do a reset and if that improves things. To close all apps : from the home screen (i.e.not with any app 'open' on-screen) double-click the home button to bring up the taskbar, then press and hold any of the apps on the taskbar for a couple of seconds or so until they start shaking, then press the '-' in the top left of each app to close them, and touch any part of the screen above the taskbar so as to stop the shaking and close the taskbar.
To reset : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.
For battery life have you done a charge cycle since you updated :
For proper reporting of the battery’s state of charge, be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).

Since upgrading to IOS 5 battery life is much less

I have upgraded my IPHONE 4 to IOS 5 and have noticed a significant change in my battery life. Any recommendations are welcomed

If your ISP is Comcast, read on....
I had similar problems with both my iphone and ipad when using my wifi, but not when using cellular. Turned out to be a Comcast issue with their implementation of DNSSEC validation. You can see my full explanation on my blog at http://blog.trif.com/?p=295. The site is being blocked by Comcast because the Microsoft portal does not meet DNSSEC validation rules. This applies to Comcast DNS Servers 75.75.75.75 and 75.75.75.76.

Software upgrade iOS 6.1.2 - since upgrading my software the battery life on my iPhone 4 goes down very quickly, will this be fixed with a further upgrade?

Just signing into this site and posting a question has used 21% of my battery life! Surely that's not right. Is Apple going to issue another upgrade from iOS 6.1.2 to fix this issue?

Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new). Try each of these in order until the issue is resolved.

New MBP 2.6Ghz, can not keep battery life when shut down

Hi
Just got my MBP 2.6Ghz, 2Gb Ram yesterday (waited more than 4 weeks on it), and already i got a problem..
After getting the MBP, i charged the battery to 100% (magsafe was green, and OS X said 100%), i had to shut down for the night (removed the power, and packed the mbp in my second skin), after 7 hours i turnd on my MBP and the battery life is now 86%, i recharde the battery to 100% and shut it down again and went to work.. after 10 hours work i turn on my MBP and the battery life i now 70%..
Why i my new MBP loosing battery when it i shut down (it is not on sleep, but shut down from the finder menu)
already checked my firmware and battery version:
Battery: v 1.3
Bootrom: v. MBP31.0070.B05
SMC: v. 1.16f10
all updates from the software update is installed

I think you did the process wrong. Try follow this:
1) Plug in the power adapter and fully charge your PowerBook's battery until the light ring or LED on the power adapter plug changes to green and the onscreen meter in the menu bar indicates that the battery is fully charged.
2) Allow the battery to rest in the fully charged state for at least two hours. You may use your computer during this time as long as the adapter is plugged in.
3) Disconnect the power adapter with the computer still on and start running the computer off battery power. You may use your computer during this time. When your battery gets low, you will see the low battery warning dialog on the screen.
4) Continue to keep your computer on until it goes to sleep. Save all your work and close all applications when the battery gets very low, before the computer goes to sleep.
5) Turn off the computer or allow it to sleep for five hours or more.
6) Connect the power adapter and leave it connected until the battery is fully charged again

Is there a fix for Mountain Lion OS battery life problem

I just bought MBP a week ago. This does not live for 7 hours on battery as advertised. It has got Mountain Lion OS on it right now. Dont tell me it is hardware issue. If it is, I would not expect Apple to sell new Macs with untested hardware....
Are you ware of any fixes to it yet?

No problems here.
Maybe you have a hardware issue?
