2012 MBP serious battery drain, help!

Its a regular 2.6 model, i get around 2 hours. I took it to the store and they did the battery test, and its perfectly healthy they say. I've disabled as many features as possible. All i do is surf teh web. I've got some youtube tabs open (no videos are running), could that be whats causing it? im using chrome..
Running 10.8.2, i keep the power cord connected most of the time, but the times its out, i can literally see the percentage race down (ok maybe not so literally, but it loses 1% every 3 minute or so).
Really appreciate any advice!

Figured out part of the problem. gfxCardStatus doesn't actually work in some/many apps, the discrete graphics stays on when in "Integrated Only" mode. If u've got a 15" MBP you might as well use "Dynamic Switching" mode, at least u'll know which graphics card is active.

Serious battery drain on iPhone 4S

Dear experts
I have a serious problem with iPhone 4S. I am on 7.0.4. My battery drains in front of my eyes...1-2%/min!!! I could barely use my phone for 1 hour or so. Sometimes I also noticed that battery reading is total chaos....it jumped down from 65% to 27% in a min. Yes within a minute! This is insane....further I tried everything based on available information. Started with setting the new iPhone....turning off unwanted stuff...background app refresh...battery calibration...every possible trick in the book. No use!! Is this a software bug or I need to replace my battery? I only remember that on iOS 6, my iphone was running well n good....Please HELP.

Update: I figured out that it was not a software bug, but a hardware. The battery for some reason looked like a chocolate bar...rough surface and soft in few areas against a flat surface feel of new battery. Of course I changed the battery and now phone is back to normal. Do not know why the battery is physically damaged. But replacing it solved my battery drain problem.

MBP A1278 Battery Drain during sleep

So I've been having issues with my Mid 2010 MBP A1278. I always charge it to 100%, but quickly overnight it drains and in a couple days goes to zero without using it at all. Does anyone have any tips? Right now I'm using OS X 10.8.5, but upgading to Mavericks in the next day or two. Below is the notes I made about when I opened and closed the laptops with battery percentages. Is this normal?
8:12 PM 99% Wednesday
Then closed lid
7:04 AM 88% Thursday Morning - checked battery for 1 minute
Then closed lid
9:40 PM 50% Friday Night - checked battery for 1 minute
Then closed lid
7:46 AM 40% Saturday Morning - started working with WiFi connectivity
8:19 AM 29% Saturday Morning
then closed lid

Not much. Mine goes down maybe 1-2% overnight, if anything.

MBP 2011 - Battery Draining While Plugged In?

After playing Splinter Cell: Conviction for a few hours, I noticed the battery had drained a few percentage points while plugged in? Almost as if the graphics card and fans needed even more than what the charger could provide. This has happened more than once, and once I've quit, the battery has no problem climbing back to 100%.
Any help would be great. Thanks!

+*Any help would be great*+
None needed
This is how your machine should be running. There are conditions, generally under a heavy load, that may require more power than can be provided by the power supply alone. During these times, you may see your battery charge slowly decrease even while your machine is plugged in. This KB article refers to MacBook Pros with removable batteries, but it does identify the issue:

MacBook Pro: Won't Turn On + Battery Draining HELP?

Bought my Macbook Pro in January, 2013. I have had no issues until yesterday, I shut it down completely the night before and took out the power cord. Turned it on the next day, in the evening and it wouldn't turn on, put in the power cord and it was a faint green. I waited a few hours and the light had turned amber then bright green and turned on as normal and ran just fine. Today, the same thing happend it will not turn on, with the power cord turning a faint green.
I have tested the power cord, I have two and they are both fine. Haven't altered or installed anything within the system, e.g. memory. Once it turns on again it I can give details on what OS version I am running and anything else necessary.
I'm freaking out that something is majorly wrong, I love this computer!

May vary from model to model, but IFixIt.com shows the one for mine @ $120.
But I'm pretty sure it's something more besides the battery

IOS 8.1.3 - Battery draining very quickly

Since installing iOS 8.1.3 on my iPhone 6 the battery has started to drain very quickly with little to no use. Anybody else having the same problem

I too was having some serious battery drain on IOS 8.1.3 on my iPhone 5S. The phone kept getting warm (like I was using maps navigation) I think I just fixed it. On the hunch that it had to be something with location services I went to the following location in my phones settings: Settings->Privacy->Location Services now scroll all the way down and Click System Services. Disable Cell Network Search, Setting Time Zone, and Wifi Networking. You can also try disabling these one at a time. I really don't need these services so I disabled them all.
Your phone should now cool down and hold a charge like it did before, mine does. Here are what those settings you are disabling do:
Cell Network Search:This tracks cell tower usage and congestion, and sends the data back to Apple for analysis as to what towers are being used the most, how you move between cell towers, and which ones are overused. It does not help your phone locate a cell tower. Turning this off will not affect your phone’s performance, according to Apple.
Setting Time Zone:Your time zone will be instantly adjusted according to your geographic location. Ever notice how as soon as you turn on your phone after a long flight, it displays the local time perfectly, even before getting cell signal? It’s this setting. If you turn it off, you’ll lose that functionality.
Wi-Fi Networking:This particular setting is interesting, and requires some explanation. As you move around a city, your iPhone is constantly picking up WiFi signals. It geotags that data (“XYZ WiFi is at this GPS location”), encrypts it so that it is anonymous and unique (otherwise the data would look like all hotspots are named “linksys”), and stores it as what Apple calls “crowdsourced Wi-Fi Hotspot locations”. Next time someone walks by that exact hotspot, their iPhone will know where they are without using GPS – because you basically already “marked” the area. Shutting this setting off will stop that info from being sent to Apple. It will not affect your phone’s performance.

My own Battery Drain Issues on iPhone 5

Hello guys, I've just created an account here to share my many issues with iPhone 5.
Well, this wasn't my Apple's 1st product, as I've had Ipod touch 2g and 3g, as well as an iPhone 3g. But it's my first time experiencing crazy battery issues with an Apple product, wich is really sad and disappoint, since this is the MOST expensive cell phone in my country (Brazil).
It all started about a week after I bought my iPhone 5. One morning I was on the bus, going to work, and my iPhone had about 99% battery remaining. 1h20 later, when I arrived at work, I had about 80% battery, so I panicked.
Suddenly I realized I was a victim of the common i5 battery drain. I was loosing 1% battery each 3~5 minutes IN STAND BY. And my settings are the same as they've ever been: wi-fi off, 3G off, 4G off (since it's not available in Brazil), brightness on minimum, no weak cell phone coverage etc. So, I shouldn't be experiencing this at all.
After reading lots of threads around the web, I realized that the ONLY solution to this would RESET AND START YOUR IPHONE AS A NEW ONE. No backups, no deleting apps and data. Sometimes removing email accounts would work, but as I didn't use this stuff, restarting my phone seemed to be the solution.
So I did it and, apparently, my problems were solved. My phone has worked perfectly for 2+ months. And then I let it fully discharge - but it's was not the first time it' happened. After I recharged for 4h, I started loosing battery really fast again, so the battery drain have came back. It was so frustrating.
Then I sent my iphone to an authorized reseller and they manage to give me a new replacement phone. They've checked my old i5 and detected a battery issue. My charger and cable were also tested but they were ok.
Well, after the very first charge on my new phone - and I've set it up as a new phone - the battery drain started again. I couldn't believe it.
So now I'm waiting for my 3rd iphone 5 in 3 months...
PS: My original iPhone 5 was bought in the USA, and the replacement one came from Brazil. Both were running iOS 6.1.4 when the issues started.
After all that, here are my conclusions:
1) In normal conditions, with wi-fi, 3G and LTE off, you should expect your iPhone 5 to waste 1% of battery every 1h30~2h15 on STANDBY. This is based on my best iphone performance and on Apple's information: iPhone 5 should have 225h of battery time (in standby) at it's best. Since 100% = 225h, every 2h15min you should expect to "waste" 1% of battery, on standby.
Sometimes, overnight, your phone might have an even better battery life: my friend only lost 1% for about 8h/9h overnight. But this is just not common. Expect to loose about 2%~3% every night with all apps closed and no wifi/3G/LTE.
2) If you detect a battery drain, GO TO AN APPLE STORE/RESELLER RIGHT THE WAY. Don't even bother trying a reset, as I did, because it might solve the problem for a while, but it CAN come back. Go to the apple store and ask for a diagnostic of your phone and battery. It will save you a lot of time.
3) There are MANY causes to battery drains. The most common ones seem to be: 1- Push notifications/email related stuff -> Reset email, internet and settings. 2- Facebook app -> reinstall app. 3- Defective battery - go to apple store/genius and ask for a replacement phone.
4) If an iPhone comes from factory with battery issues, expect AT LEAST ONE other issue. My original phone's touch screen was unresponsive when charging on PC and connect to iTunes and my replacement phone's microphone was not working properly. So expect other defective parts
5) With my experience, I've realized I might have discovered A NEW CAUSE TO BATTERY DRAIN: A DEFECTIVE NANO-SIM CARD. Why? Well, because it's the only thing that I have used on both my iPhones (original and replacement ones). And it's the only thing thats has never been tested (both my charger and cable were tested on apple's reseller and were ok). And in my replacement phone, after I removed the SIM, I started loosing 1% battery every 1h20, when on stand by and with no wi-fi, 3G or LTE. So, if you have a battery issue CONSIDER THE SIM CARD TO BE THE PROBLEM.
Also, when my replacement phone was near any amplifier/pc speaker, it would make the amp make that "call or text incoming" sound. (to understand this, put your phone near an amplifier/speaker and ask for someone to call you). This makes me believe that the SIM card was, somehow, defective and making my phone receiving data (and I mean only telephone data, like related to calls and sms) when it shouldn't.
That's all my friends. If anyone has ever experienced this crazy issues, please try to help me. I'm getting a new sim card, iOS7 and my 3rd replacement phone and let's see if it works as it should.
Sorry for the MANY mistakes, my English is not good =\.
Cheers from Brazil!

Hi Folks,
iPhone & iPad2 battery drain issue SOLVED!!!!!
I had a serious battery drain problem on THREE devices using different iOS .... it was a simple fix and had certain characteristics that you may be able to relate to ......
Devices;     16GB iPhone 4 with IOS6
                  16GB iPhone 4S with iOS7.06
                  32G iPad2 with iOS7.04
On or about Feb. 28th all three devices started to drain the battery like crazy losing about 20%/hour on the iPhones and 10%/hour on the iPad2 .... After messing around with settings, browsing forums and looking at what was common between the three devices I concluded the problem was with a single Microsoft Outlook/Live/Hotmail email account in the iOS native mail app .... I deleted the email account on all three devices (along with other unrelated Microsoft accounts on each device) and did a hard reboot (hold HOME and top LOCK button simultaniously for about 10 seconds until the apple logo appeared).
I then re-created the common Microsoft Outlook/Live/Hotmail account on all three devices in the iOS native mail app ...... SUCCESS! Now all three devices are behaving normaly with respect to battery drain ......
Hopefully this will be useful to others in this thread ..........

IOS 7.1 battery drain iPhone 4S

While the performance increase on iOS 7.1 appears genuine - I'm experiencing serious battery drain on my iPhone 4S (64GB model).
I have parallax disabled as well as background app refresh disabled.
I updated from iOS 7.06 to 7.1 via USB cable attached to my Mac Pro and the latest version of iTunes running on Mavericks latest version as well. I had closed all apps and done a reset before connecting to iTunes where I did a backup and sync prior to updating.
The drain I'm experiencing is during usage, not standby as much. When I use my standard apps (mail, safari, txt, etc.) I'm seeing the battery drain about 1% per minute. I'm not using GPS or bluetooth.
I followed one suggested on Apple Forums to drain battery to about 40%, then do another hard reset. Doesn't seem to help.
Anyone know of similar issues or what to try next?
Are there any tools available to see what apps might be running in the background that are causing the processor to drain the battery so fast? And yes I am now closing all apps after using them to try anything to save battery.
Very tempted to find a way to downgrade to 7.06...

Thought I'd reply to this seen as no one else has, I am also experiencing very similar problems with my 4s and by the looks of it is it's across all handsets. I've never had any battery issues with my iPhone even 7.0.6 was fine, but since updating to 7.1 the battery is ticking down very fast. I fully charged in the morning and left it in my locker all day at work when I got my hands on it it's gone down to 52% just on its own!!
I really hope they sort this out fast the irony is 7.1 was supposed to help battery life!

IPhone 5 battery drain since iOS 8.2 update

hello,
my name is Udi, from Israel.
i have an iPhone 5 which i purchased in June 2013.
since the beginning, i have always kept the battery saving "rules", including correct charging of a lithium ion battery, auto-brightness off, reduce motion on, push notifications off, background app refresh off, cellular data off when not in use, etc. etc.
since updating to iOS 8, my battery life has decreased a little. but since updating to iOS 8.2 a few days ago, i have experienced, what is in my standards, a serious battery drain. e.g. when i sleep, with my iPhone on airplane mode at night battery decreases by ~15%.
i have tried everything, including restoring the phone and using a backup.
what can i do?
will a restore from scratch (without using a backup) help?
thanks in advance =)

If this does not help, get your phone checked by visiting an Authorized Apple Service Provider or Apple Store next to your place, or contact Apple Support and talk to them. They can check the battery online.
You can also visit this page to do that: iPhone - Contact Support - Apple Support
Click on Apple Support, then on ->Battery, Power &Charging ->Battery questions and troubleshooting, and follow the instructions.

Iphone 4s IOS 7.0.4 update battery drain issues

I hope this gets to apple in regards to the issue of the battery drain. I have been following several discussions for the past couple of weeks and everyone seems to have some type of idea on what the problem is. I'm not a service tech or gadget know all, but I have been performing several "Nonscientific" test to see what is draining my battery.
I have a 4s that has always had good battery life. It seemed to run consistent to what was detailed in the product specs. I would only need to charge it every other day on limited use or the next day with heavy use. After updating to the latest update (IOS 7.0.4), the battery would drain in less than a day on limited use which is a couple of text, couple of email checks, 3 to 4 phone calls at less than 10 minutes each - no internet searches or game play.
So, after reading everyones suggestions in the forums and trying them, the battery still drained just as fast, if not faster. I read a post somewhere regarding “Bluetooth” constantly searching. So, I saw mine was doing the same. Someone replied to that person that it should not be the issue, as it does not use much power to run its task. (I found they were wrong)
Here is my nonscientific test, but a good one. (for the record I had nothing on in the notification center, Do not disturb off, only thing on in Privacy - location services was google maps, Siri, Yelp, and Find my phone; iCcloud was off; background app refreash was off; email fetch data was off; everything else was off)
Day 1 - I fully charged my phone several hours, I unplugged it at night before going to bed, did a hard reset to make sure every app was off, and only opened the settings app and made sure the Bluetooth was onand searching. I checked my phone 6 hours later and saw the battery drained from 100% to 56% with no usage other than just being on and in sleep mode. That would mean it drained at 7.3333 % an hour. Some would say that acceptable. - Its not when there is no usage. The battery would die in 13 hours with no usage.
Day 2 - I repeated the test (as above), but turned off the bluetooth. I checked my phone 6 hours later and saw the battery did not drain at all. I started with a 100% and battery was still at a 100% with no usage other than just being on and in sleep mode. I opened a couple of apps and closed them to prevent them from running in the back ground and noticed I lost about 2% of charge after usinging it checking an app or 2. I put it back to sleep mode and checked it again in an hour and saw it only drained 3% down to 97%. Very acceptible.
Day 3 - I repeated the test, but during regular day hours with limited use of the phone (with bluetooth off). I was back to getting close to a normal battery drain I was experiencing prior to the update. I know that IOS 7.0.4 uses a little more battery power to run as it has different features and abilities, so the battery drain was not like it was before, but a lot better.
So, my experiment concluded to me that the new update is causing the bluetooth searching to run in the back ground continuously and causing the battery to drain unacceptably fast on my phone. This is a program issue that can be fixed by Apple. I find it unacceptable to have to control my bluetooth manually, as I never had to do it before and I shouldn't have to do it now. I hope Apple will fix it soon. I‘ve been a apple product person for years, and enjoy the products, but lately they have been not been satisfactory in the phone business. I have been playing with a samsung galaxy thats looking very promising, if apple doesn’t fix the issue everyone is having, they will loose business to competitors.
Please fix the issue!

HT201412 Battery drain - iPhone is draining power fast

My iphone 5 is losing power fast - battery is draining. Haven't experienced this before. I've followed some basic steps to try and conserve powers within the settings features, but still drains fast. Concerned the battery may need to be replaced. Anyone else have this option - have any recommendations or trouble-shooting?
thanks

Smartband talk SWR30 battery drain

I recently got a smartband talk, and although I really like the device, when connected to my phone, the device prevents the phone from going into deep sleep, and that in turn causes serious battery drain on my Z3. The phone barely makes it a day. I really want to use the device, but not sure I can stomach the battery drain. Any ideas how to fix this?

Sorry to hear that you're having issues with the battery performance.
Could you please check which version you have of Smartband Talk & Lifelog?
The version for Smartband Talk you will find in the about menu in the Smartband Talk application.
The version for Lifelog you will find in the Settings/About menu in Lifelog.
If you also could post screenshots from Settings -> Power management -> Battery usage and tap the items that's used most battery there that would be great.

Battery drains when power connected

Hi,
Early 2011 MBP 17inch battery drains when the power is connected. It seems to be that when the system is having some load battery is discharging even when the power is connected. Is this normal?
Regards

Yes it is normal, For Mac's that is. Apple doesn't supply a large enough AC power supply to both charge the battery, or stop it from being used, when the system is under heavy load. Once you start to run the system hard it will draw power from both the AC and the battery.

New 15-inch MBP (2008 MPB) battery drained to 84% in 15 mins. Help.

Hi there! I just popped in a brand new 15-inch MBP (square) battery into my 2008 MBP with Lion 10.7.4. It has drained to 84% in about 15 mintues. Is it a defective battery or a problem with caliberation? Thanks!!!

Calibrate it, and then you'll find out whether the problem is/was with the battery or its calibration.

MacBook Air 2012 Severe Battery Drains While Sleeping

Hi there,
This isn't any new but I've looked through all posts I could.
I got a refurbished MacBook Air 2012 in July. In the first 2 weeks it worked fine (or I was noticed).
Then I noticed the battery drains fast while the system sleeps.
I have done tests in the past weeks; almost 20% of battery drain after slept a day.
I have tried everything I could: turn off PowerNap, no wake from BT devices, erase and reinstall OS
None of above helped.
I have tried to modify hibernatemode to 25 and it worked ok; 2% of battery dropped after 12 hours.
I took this to Apple in Taiwan and they told me they couldn't do anything about it because they think it's software conflicts which does't really have a solution but wait for OS updates. They did run a diagnostic and everything turns out to be fine.
I just did reinstall the OS again and I'll see whats going on tomorrow morning.
If still not getting better I will just use hibernatemode 25.
Anything recommandation is more than welcome.
Thanks.
My OS version is 10.8.3.

Tried hibernatemode to 25 and still not helpful at all.
Battery drained 8% after 10 hours of sleep while mode 25 should put my macbook air into deep sleep and consume very minimal power.
