Battery life reduces to half with RAM upgrade

HI Folks,
I have a strange case and need expert help.I purchased Macbookpro early 2011 ,15inch with 2z4GB RAM approx 2 months ago.The Battery lasts for approx 4hrs.
Recently I removed the original RAM (2 x 2GB) which were rated at 1333Mhz and replaced them with 2 x 4GB RAM rated at 1066Mhz.The battery life went down from 4hrs to 1hr 50 minutes without using any application,when i swapped the RAM back to original it shoots up back to the normal battery timings (approx 4 hrs)
I am not able to understand wether it is because of lower bus speed RAM.I am using the samsung brand
regards
Zubair

Reset the SMC
Reset the PRAM
Calibrate the battery

Battery life reduced by nearly half after Maverick upgrade

Hey guys,
As for the setup, I'm currently running a MBPr mid 2012 2.3 GHz i7 16GB DDR3 w/ 256 GB SSD. (I doubt it's relevant but only 170GB is allocated to OSX and the rest to a BootCamp partition for Windows).
Now, for the problem, immediately after upgrading I noticed a drastic drop in battery life. I've done a bit of research and found a few similar cases but have yet to find a solution. I understand that right after the install Spotlight indexing drains the battery for a while, however I'm 2 days in and am still experiencing this issue. I should also add that during those 2 days I drained the battery completely and did a full charge.
I've already tried to rebuild the Spotlight index following these steps: http://osxdaily.com/2012/01/17/rebuild-spotlight-index/
On top of rebuilding the Spotlight index I've also tried an SMS reset following PlotinusVeritas's steps from another thread:
SMC reset
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Neither of these steps fixed the issue.
My battery life prior to the upgrade was 7 hours (+- a few minutes) and after the upgrade it is at 4 hours (+- a few minutes).
Any assistance would be very much appreciated.
Thanks in advance,
Noah

Well, I talked to the german telephone support on monday, they wanted to know the current capacity, load cycles etc, if I had tried resetting the SMC and calibrating the battery, and in the end they just sent me a new battery (I'm still inside the 12 Month guarantee time).
This arrived yesterday, and I'm using it after calibrating it directly .. so far it works without problems, and the MBP has not shut down on me suddenly, but has shown the 'low battery' warning and went to sleep as expected at 5-10% battery left.
So, at least for me the apple support seemed to agree that the battery was broken .. what caused it, no idea.
The new battery should have received the 1.3 battery update when I installed it, don't know how to check what version is on the battery.

Battery life horrible after 1.1.2 upgrade

Hello All-
I need some assistance here... Right after I upgraded to firmware rev 1.1.2 I noticed my battery life has reduced drastically. Out of a full charge with standby only, I'm lucky to get 3hrs. out of it (and I'm not exaggerating) . I do not have wifi turned on and have not used the phone any differently since rev. 1.1.1. I have read that Apple appears to have increased the processor speed in this latest firmware upgrade thus possibly having something to do with this issue I'm having. Does anyone know what the fix is here because it's really starting to annoy me
Thanks!

I haven't seen any change in the battery life of my iphone after getting 1.1.2 update. Seems nearly exactly the same. Normally 2-3 days of standby time and anywhere from 6-10 hours usage depending on what I am doing.
Also I don't know if those processor speeds are correct. I thought I saw in an article just after the iphone was released and dissected that it used a processor that ran at around 600Mhz, could be wrong though.
edit - quick google search brings up lots of hits. It appears to be an ARM processor at either 620-667Mhz, possibly made by samsung.

N70 v5.0638.3.0.1 battery life reduced issue

I updated to v5.0638.3.0.1, and it seems like a BIG ISSUE of this FW release is that the battery drains a lot faster.
for example, fully charged my phone saturday morning, used it for 4-5 SMS, 4-5 minutes of 3G Mobile Internet, maybe 5 minutes of calls, and on sunday morning, the phone battery indicator had 2 lines...
also, other N70 users with last FW have complained that the battery life has been reduced since they updated to v5.0638.3.0.1 . So please, Nokia, do something about this issue, it's very important.
Users with N70 v5.0638.3.0.1, please report here if you feel like your battery life has been reduced.
Previous phones: 3330, 3410, 3510i, 3200, 6230, Nokia N70, Nokia N73, Nokia N82, Nokia 5500 Sport & Nokia N97
Current: Nokia N900

is this not an important issue ?

Battery Life on iPhone 5 with IOS 7.0.2

Hi all,
What's the average battery life on iPhone after the upgrade to IOS 7.0.2?
I tried to put my phone (with 100% full battery) on Airplane Mode before I went to bed (around 11pm).
When I checked my phone at 6.30am in the morning, it's only 1% battery left --> 7 hours on Airplane Mode???
The next night, I put my phone on standby mode (Wifi on, Location Services Off, Bluetooth Off, 3G/4G off) same time (11ish)
Next morning at 7am, 5% battery left --> 8 hours on standby with just Wifi On.
I found it a bit weird because before the IOS 7 upgrade, if I put my phone on Airplane Mode, it will last for more than a day.
Wondering if any of you guys has the same issue with the battery?
Thanks.

I received an iPhone 5 for Christmas and had an iPhone 4.S previously which had no battery issues at all. The new phone is diabolical in terms of battery life. I have done all the things that people recommend on here to try and extend the battery life but to no avail. Just sitting overnight with nothing running in the background drains the battery considerably. What else can I do? I have AppleCare on this phone so the people there offer to replace the phone for me BUT the replacement phone does not arrive in a new box and the respresentative was very fuzzy about the fact he would/could not assure me I would receive a brand new phone in its' box. He just kept saying it will be a 'replacement phone' which is totally unacceptable as this phone is unlocked so we paid full price for it. The phone is not reliable - whilst out for a full day's ski-ing (I was not ski-ing, just hanging around!) and using the phone for very light Internet browsing and only a few short e-mails, the battery just drained away in front of my eyes so I had to turn it off completely as I have no car charger yet and certainly had not thought to take my electrical charger with me (we won't even talk about the stupidity of making the new charger not fit my other Apple products (three of them!).
I really am so disappointed and don't know what to do next. As BCCconvert asks, what can we do??? thanks for any help offered.

Why is my mac's battery life decreased and got slower after upgrading to lion?

Thank you for helping,
I am using MacBook Pro (13-inch, Mid 2010) and beginning of this summer I upgraded it from snow leopard to lion (from apple store). After installation my mac got slower,it consumes the battery very rapidly and starting time increased. I searched the reason on the net and this time I did a clean installation. I but the problem insisted. last week i updated to 10.7.5. this time i see that coloured spinning wheel even i logging in. I did all the updates and battery calibration as mentioned in apple support communities but nothing have changed. I don't use any grafic programs etc. I only use safari, firefox, iphoto, iwork and microsoft office for mac. My english and my computer knowledge is not very good. So, if you answer my problem please will you explain as much as simple.
Thanks anyway.

A couple of things...
...first, you might want to make certain that your internal drive is selected as the Startup Disk under System Preferences. If it's not, this can sometimes lead to a problem of your MBP 'searching' for a boot drive at startup. Second, you might want to read ds store's article - Why is my computer slow? A very handy reference guide with some good tips.
As to your decrease in battery life - that has been reported by some users as a problem with both Lion and Mountain Lion. See the "More Like This" to the right of this page.
Can't offer any real solutions - read Mr. store's article and see if you can find anything that helps. You might also want to download the free "Battery Health" from the App Store and keep an eye on your battery when you're using it.

Lumia 800 battery life is now worse with 12070 fir...

Upgraded the firmware to 12070 3 weeks ago (UK 3 customer) and for a couple of days I got the enhanced battery life - great.
Within a week however I was back to square one, or worse, with a full battery charge lasting 12 hours maximum. Probably worse than it was before 12070.
I take off the charger in the morning and within 20 minutes of browsing maybe a dozen web pages, couple of texts, I'm probably down to 90%.
not making calls, or sending many texts/emails/tweets... or using many of the other apps (because the battery runs down)....
any advice?
Hardly using the phone and still seeing it out of power by 8pm every night wasnt exactly what I signed up for.
Am I expecting too much?

When talking battery drain, it's important to know what your Lumia has going on in the background:
How many apps w/ background access?
What apps are they?
How many email accounts do you have connected?
What are their sync intervals.
Do you keep bluetooth on/paired while idle?
WiFi?
is your max data connection E or 3G?
Do you find that if you're using 3G that it's on E a lot?
All of these things contribute to power drain and it's good to know. Regardless I think you need to contact Nokia for a replacement. Here's wny?
My Cyan Lumia 800 is 3.5mo old. I gave it 12070 well over a month ago.
4 email accounts. 1 is "as they arrive", the other 3 sync at 1-2hr intervals.
I keep WiFi on at all times.
Same with bluetooth.
I have 2 background tasks: Appointile & Clever ToDo
Max data connection E while at home and 3G when not home.
When I go out and about, I play music via bluetooth earphones for 1-3 hours. I play a bit on the web and a few games throughout the day. Maybe a phone call or two. More games in the evening and then setting it face down when I sleep. I wake up and still have over %25 battery left

3 beeps with ram upgrade

My Macbook beeps after installing ram upgrade. Doesn't matter what maker. I know that all the specs are right but I keep getting the 3 beeps to indicate the banks are empty, not that it's incompatible RAM type. What do I do now?

When I put the old memory cards back in, it starts but only showing half the RAM. When I switch positions (slots) for the cards, the empty banks also switch positions so that seems to indicate a problem with one of the original cards now also. Am currently the hardware test. Just done in record time, "no trouble found." However, profile is showing only half the RAM actually installed.

Battery life of 15 Minutes after Firmware Upgrade

Now that my system has had the firmware upgrade, I dont get more than about 5 minutes of battery life.
Prior to that I was getting a good 2.5-3 hours ish.
Now, it dies after 5 minutes.
I find it suspicious that this happened immediately after the FMC firmware upgrade.
I understand that the firmware cannot be downgraded easily.
Or is there, please let me know.

Recently my battery on my 15" MacBook started reporting 75% in the OS but the system would shutdown without notice -- also, when I put the computer to sleep (sometimes for only 20 minutes) it would completely lose its charge and shut down.
This started happening after I loaded the new firmware, but I thought it was related to a failing battery, not the FW update… now I’m curious.
I purchased a new "spare" and sent the original one back to Apple for testing. The spare has not had any problems since, but it has only been a few days. I've heard nothing back on the other battery.
I’ll post back if I have any problems with the replacement.

HT1490 battery life reduced after updating to osx mountain lion

I used to have a battery life of 7hrs+ but after updating my os to mountain lion 10.8 it has reduced to 3hrs. I've bought this macbook in august and i dont think there'll be any issue with the battery for just 3 months. I guess this has to be something related to mountain lion. Can anyone please suggest any method to increase my battery performance again...

Battery life on my 2012 mbp is also terrible, getting 2 hours out of it. They checked the battery and said its perfectly fine..

Battery life cut in half all of the sudden

The battery in my macbook pro would last about 4 and a half hours browsing the internet and watching some youtube videos. but oddly just this morning after i unplugged it, it only lasted about 2 and half hours. I hadnt done anything but browse a few websites and watch some youtube videos. i tried draining the battery, and then recharging, but it didnt work.
the battery has been running hotter than normal lately, so the fan has been running more often as well. i thought maybe the fan constantly running would be the reason for the battery life issue, but would the fans really cause my battery life to be cut in half? i didnt have this problem this past summer, when temperatures were in the 80s and 90s and my macbook was hot all the time, the battery would still last normally.
what should i do about this?

ive done that. no unusual programs are running. and about watching youtube videos. why would it last 4 hours yesterday, and now. while doing something like browsing a website, something that should consume less battery. it only last 2 hours?

Low battery life, heat or noise with Macbook pro? SOLUTION HERE

Low Battery?
Warm unit on Idle?
Loud fan?
Likely solution is here..
I have a new 15" and had these issues, found the only working solution in the thread below, safe and easy to use. If you are worried do a
time machine backup before doing this.
Go here
https://discussions.apple.com/thread/3191543?start=0&tstart=0
Read post #2, put the command into your Terminal (Found inside launchpad)
- That command is the following "sudo launchctl unload -w /Library/LaunchDaemons/com.citrix.agadminservice.plist"
type password when asked ( you wont see any characters but it will be accepted when pressing enter)
Restart, battery, heat and noise issue is completely solved, lion is fixed.
You now have a very high quality product, that functions like it should. Macbook Pro still owns.
Hope this helps everyone out.

Same problem with shortened battery life here with 10.6.2 (2009 unibody 15" MBP 2.53 GHz.) Shutting down and removing the battery seems to have brought fully charged battery life back from less than 2 hours to over 5 again. Didn't bother holding down the power button with the battery out though.
A few notes:
1. Prior to the shut down + battery removal, I had noticed unusual warmth despite the CPU being only lightly loaded. Activity monitor showed no app using more than 4% of the CPU, with just a few apps running (Safari, Mail, iCal, Finder).
2. Months ago, just a PRAM reset seemed to fix the problem, possibly with 10.6.1 or 10.6. Can't remember for sure. But PRAM reset doesn't help any more with 10.6.2.
3. I have never reset the SMC.
4. I don't recall this problem happening with any of the 10.5 releases. Just with 10.6.x.
5. The bottom of the MBP's enclosure is cool again after the shutdown + battery removal.
6. I am also running 10.6.2 on a 2008 aluminum iMac (20" 2.4 GHz) and haven't noticed any unusual temperatures, but it's much harder to tell. And of course, there's no battery life to measure.
I'll see if the problem returns again, but it really seems like a Mac OS X problem instead of a firmware or runaway app problem. Maybe some daemon is stuck in a busywait loop or something?

Macbook Pro (2012 April) Battery Life Reduced A Lot!

Hi guys I got a macbook pro sometime around April 2012 and the battery life just went down drastically in a couple of months i have no clue why before it used to show upto 7 hours something initially but then it started showing only 4 hours or so i feel something went totally wrong with the battery is there any way to fix it please give me some helpful suggestions thanks! By the way i must mention this today i was watching the percentage meter it makes absolutely no sense first it showed 7:08 today on 98 percent then within few minutes it went to 6:28 in 97 percent so i think somethins is very strange with the battery. Just yestarday on 99 percent it was showing 4:38 hours please help me fix it.

As others have said the battery itself is perfectly OK.
The reason your remaining charge shows only 4:38 after it has been fully charged may be explained by one or more processes that are responsible for excessive power demands. To isolate that potential cause read: Runaway applications can shorten battery runtime, affect performance, and increase heat and fan activity
Because i have turned of put harddisk to sleep as someone on forums suggested to another user that turning that off can help stop freezing problems when opening lid

Problems with RAM upgrade iMac G5 1.8GHz

Stuck - Need Help!
I've previously upgraded up iMac to 2 500Mb RAMs and felt recently that it needed that little bit extra, so I ordered two 1Gb chips from crucial.
Followed instructions to T, but with the two new chips in, the machine won't load.
Interestingly, it boots up with the following RAM combinations
old 500MB + new 1GB (in any combination) - recognised as 1.5GB
one new 1GB RAM (again either one) - recognised as 1GB
I spoke to crucial who said that as the RAMs work individually, there isn't a problem with them, it could be a Firmware issue. I've upgraded all my software, and don't know what to do next?
Anyone overcome a similar problem in the past?
Thanks

I'm experiencing something very similar to shaow. I'll share my experience in gory details - sorry for the long post but I've spent more hours trying to stabilize. I should have worked the hours at walmart and bought a new iMac with the money I could have earned
Anyway, here goes:
Two iMac G5 1.8Ghz 17" (both Fall 2005 model), will call one A and the other B.
Prior to attempting ram upgrade: A, config working fine: both a config using 1GB slot 1, 256MB slot 2 and a single 1 PC3200 1GB stick. OS X 10.4-10.5.7. No problems. I did have the motherboard replaced under warranty after having sleep problems - capacitors were expanded. No problems since that motherboard swap.
Prior to attempting ram upgrade: B, config working fine: 2 x 256MB sticks. OS X 10.3.9
Ordered 3 PC3200 400Mhz 1GB sticks from Data Memory Systems.
Upgraded A: Added 1GB stick = 2GB total
Upgraded B: Removed both 256MB sticks from B and added two 1GB sticks = 2GB total
Booted B, experienced gray screen of death with the multi-language crash message - somethign like: 'Please hold down the power button and restart'. Power cycled B, booted off a retail box DVD of OS X 10.5.6. Began upgrade to 10.5.6. Gray screen of death part way thru upgrade. Power cycled, gray screen of death again during early boot phase.
Decided to run tests on B. I could not locate the Apple Hardware Test (neither on system dvd 1 nor on a separate DVD). I resorted to using TechnoTools Deluxe which was included with AppleCare box. No hardware problems found including on the 2GB memory.
Removed both new 1GB sticks, pulled older working 1GB stick from A and installed into B. Completed upgrade with just 1GB memory on B to 10.5.6 and subsequently pulled down all updates for OS X 10.5.8. Powered down, added second 1GB stick to B, booted into 10.5.8 successfully. Repaired disk permissions, restarted. Began using applications, then after only about 5 minutes experienced gray screen of death. Powered down, removed new 1GB stick, replaced with one of the two remaining new 1GB sticks. Read about reseting PRAM/NVRAM. Followed steps to reset PRAM then decided to do the reset NVRAM within openfirmware. Started back up and logged into 10.5.8. Ran several applications - did not experience gray screen of death after about 20 minutes use. Have not had time for further tests on B yet.
Back to my saga with A (my original iMac G5 that was working fine with 1GB stick on 10.5.7):
Called Data Memory Systems and they sent me a replacement for the 'bad' 1GB stick.
While I was waiting for the new 1GB stick from DMS, I was struggling to get machine fully updated. Software Updater was failing with the weird network error (network was fine) and after following steps to troubleshoot, I backed up the user accounts and decided to reinstall OS X fresh from the 10.5.6 retail box (family license). Finally, I had OS X 10.5.8 all fully updated on the 1GB iMac G5 (A).
New memory arrived, installed 2nd 1GB stick. Booted up, immediately I got the gray screen of death. Restarted, booted up got about 5-15 minutes use then gray screen of death. Puzzled, I called DMS who said unlikely I got 2 bad sticks. They suggested I try memtest. So I did...
So on A, I first ran memtest from single user mode on the 2GB config. It crashed immediately with some 'Unexpected' error. Did not look like a memory error. I powered down, removed 2nd 1GB stick, and ran memtest from single user on the 1GB stick. Ran all tests 3x over a couple hours - no problems found. Retested after swapping the 1GB stick for the other. Both tested fine. Installed both sticks again and ran memtest all tests, one pass (didn't want another 6 hours lost) on the 2GB config, and all tests passed. Booted up and got gray screen of death - I don't recall if it was on bootup or after running but I ran fsck with no disk problems found, then restarted, logged in, ran disk utility to repair all permissions. Some repairs were made. Restarted A, reset PRAM and NVRAM again, booted successfully.
I haven't had much time to run extensively apps on A yet. It's sleeping as I type this on another mac. My next test will be to reset SMU.
I'm starting to wonder if the original iMac G5 has firmware problems that would prevent it from being unstable with two 1GB sticks??? My experience on two identical models of iMac G5 plus reading this post with VERY similar behaviors and after all the normal tests. I've concluded the memory is A-OK and something more sinister is lurking...
Any thoughts are appreciated.

Battery life shortened & other problems with 3.1.1

I have a 1st gen iPod Touch and my battery life went from about 12-15 hours (I could use it 2 days in a row at work) to 6 hours or less as soon as I installed the latest software update. I also haven't seen the wifi bars once, even though I haven't had problems connecting to the internet. (They don't show blank bars, just no bars at all.)
Anyone else having these problems? The battery life is driving me crazy.
iTunes did crash on me partway through the install and I ended up having to restore my iPod completely, so I'm trying to figure out if that caused these problems or if it's a software issue.

i just finally updated to 3.1.2 from 2.something, and the first day i noticed a HUGE loss of battery life, over 25%. this is ridiculous. this is a frist gen that i have had no battery problems until now. i could listen to music for 5hrs and then use wifi for 3 hrs and id still have life left, now on a full charge, the battery is dead just listening to music for a couple hours it dies. now i know this is an older ipod, but for this to happen the next day after an update, give me a break...
