Check battery life
I have two ibook G4 batteries and was wondering how I would go about checking to see which has the better life, or in other words, which holds the better charge.
I am selling one of my two ibooks but I have been using both and would like to keep the better of the two ^_~ so I am just trying to figure it out...the values on the computer are off so much I don't really trust them
Search for Coconut Battery on Google. Download, and run the software. It will give you very detailed diagnostics on your battery, beyond system profiler and iStatPro. You will probably want to calibrate the batteries before running the software. To calibrate, fully charge the battery, then run the machine until the battery life causes the computer to shut down. Follow this with another full charge and the battery should be calibrated. After the calibration is the best time to assess battery life.

I'm trying to check my battery life on my nano and I read the instructions given by apple (http://docs.info.apple.com/article.html?artnum=61475), but i am still confused on a couple of things. First, I wonder whether or not I have to have my earphones plugged in during the test, and secondly what volume to test it at.
Thanks!I'd keep the headphones in, but you don't have to. Put the volume at around 50%.

How to checks battery life
If you can, visit an Apple Store or Authorized Apple Service Provider to get your battery checked, or contact Apple Support:
How do I arrange iPhone Battery Replacement Service?
Battery Replacement Service may be arranged through your carrier (except AT&T and Virgin Mobile) or Apple. Please do not send any accessories with your iPhone.

All of a sudden today my battery life just started dropping off on my iphone 4s. I charge it every night. I double clicked the circle button on the bottom to see what was running and there was minimal running but i turned them off anyway. I checked back in a little bit, the same, turned the couple things off again which were like phone and messages... nothing major running. Battery percentage still plummeted til it just turned off.
Are there apps on your phone right now?
I think one of your apps is causing this.
The only way to find out is to delete them all and then add them one by one to see what app maybe causing this.
Especially if you've gone thru 3 iphones already.
When you restored as new - did you sync back your stuff - apps/music or did you restore from backup? -
My new ipod touch's Battery life is extremely short
I bought 10 days ago the latest iPod touch and it is getting very poor battery life.
Even without using multitasking and with having notifications turned off, it is running from full to empty in less than two hours.
What is it that I have to do between all the things people recomend?
- Reset Network Settings
- set it up as a new device with no apps
- Powering off every night
- Shutting down Wi-fi all the time
- turning off push mail, notifications, etc
- Turning off "Location Services"
I've tried doing the lasts 4 things and nothing improved..
Or is it just because it's new and in the future it'll work longer?
Thanks you all for your useful answers!You might check out this thread for possible help.

What follows is a grouping of some of the most fruitful procedures - from what I've seen in the biggest battery life issue thread - and some background information and discussion for solving or improving the battery life with the iPhone 4S and may be applicable also to devices on which iOS 5.0/5.0.1 has been applied. Credit goes to the respective users who contributed this information to the forum and they should be commended for doing so. This is not a final listing. The goal here is to provide a first stop sort of knowledge base document for newcomers instead of having them perusing the never ending threads where the wheel is reinvented on every page...
Please don't post your questions, usage screenshots, or claims that it worked or not for you or anything here except PROCEDURES/DEBUG STEPS/SOLUTIONS or improvements to the procedures already listed here. Try to use point form and to be as concise and clear as possible. Hope all this helps.
Thank you and good luck!
General info and specs
First, take a look Apple's battery tips, info and specs(obligatory reading for all Iphone 4S users - read it once and for all):
http://www.apple.com/batteries/iphone.html
http://www.apple.com/batteries/
... you didn't read it? loll Always remember this i.e. the definition of "usage":
Usage: Amount of time iPhone has been awake and in use since the last full charge. The phone is awake when you’re on a call, using email, listening to music, browsing the web, or sending and receiving text messages, or during certain background tasks such as auto-checking email.
I'm still not convinced you read the links so here's what Apple has to say in terms of fine tuning your battery life:
Optimize your settings
Depending on how they are configured, a few features may decrease your iPhone battery life. For example, the frequency with which you retrieve email and the number of email accounts you auto-check can both affect battery life. The tips below apply to an iPhone running iOS 5.0 or later and may help extend your battery life.
Minimize use of location services: Applications that actively use location services such as Maps may reduce battery life. To disable location services, go to Settings > General > Location Services or use location services only when needed.
Turn off push notifications: Some applications from the App Store use the Apple Push Notification service to alert you of new data. Applications that extensively rely on push notifications (such as instant messaging applications) may impact battery life. To disable push notifications, go to Settings > Notifications and set Notifications to Off. Note that this does not prevent new data from being received when the application is opened. Also, the Notifications setting will not be visible if you do not have any applications installed that support push notifications.
Fetch new data less frequently: Applications such as Mail can be set to fetch data wirelessly at specific intervals. The more frequently email or other data is fetched, the quicker your battery may drain. To fetch new data manually, from the Home screen choose Settings > Mail, Contacts, Calendars > Fetch New Data and tap Manually. To increase the fetch interval, go to Settings > Mail, Contacts, Calendars > Fetch New Data and tap Hourly. Note that this is a global setting and applies to all applications that do not support push services.
Turn off push mail: If you have a push mail account such as Yahoo! or Microsoft Exchange, turn off push when you don’t need it. Go to Settings > Mail, Contacts, Calendars > Fetch New Data and set Push to Off. Messages sent to your push email accounts will now be received on your phone based on the global Fetch setting rather than as they arrive.
Auto-check fewer email accounts: You can save power by checking fewer email accounts. This can be accomplished by turning off an email account or by deleting it. To turn off an account, go to Settings > Mail, Contacts, Calendars, choose an email account, and set Account to Off. To remove an account, go to Settings > Mail, Contacts, Calendars, choose an email account, and tap Delete Account.
Turn off Wi-Fi: If you rarely use Wi-Fi, you can turn it off to save power. Go to Settings > Wi-Fi and set Wi-Fi to Off. Note that if you frequently use your iPhone to browse the web, battery life may be improved by using Wi-Fi instead of cellular data networks.
Turn off Bluetooth: If you rarely use a Bluetooth headset or car kit, you can turn off Bluetooth to save power. Go to Settings > General > Bluetooth and set Bluetooth to Off.
Use Airplane Mode in low- or no-coverage areas: Because your iPhone always tries to maintain a connection with the cellular network, it may use more power in low- or no-coverage areas. Turning on Airplane Mode can increase battery life in these situations; however, you will be unable to make or receive calls. To turn on Airplane Mode, go to Settings and set Airplane Mode to On.
Adjust brightness: Dimming the screen is another way to extend battery life. Go to Settings > Brightness and drag the slider to the left to lower the default screen brightness. In addition, turning on Auto-Brightness allows the screen to adjust its brightness based on current lighting conditions. Go to Settings > Brightness and set Auto-Brightness to On.
Turn off EQ: Applying an equalizer setting to song playback on your iPhone can decrease battery life. To turn EQ off, go to Settings > iPod > EQ and tap Off. Note that if you’ve added EQ to songs directly in iTunes, you’ll need to set EQ on iPhone to Flat in order to have the same effect as Off because iPhone keeps your iTunes settings intact. Go to Settings > iPod > EQ and tap Flat.
Usage specs for the 4S - http://www.apple.com/iphone/specs.html:
Talk time: Up to 8 hours (12.5% per hour drain) on 3G, up to 14 hours (7.1% per hour drain) on 2G (GSM)
Standby time: Up to 200 hours (0.5% per hour drain)
Internet use: Up to 6 hours on 3G (16.6% per hour drain), up to 9 hours (11.1% per hour drain) on Wi-Fi
Video playback: Up to 10 hours (10% per hour drain)
Audio playback: Up to 40 hours (2.5% per hour drain)
So a scenario of normal usage could be for example: 4 heavy hours of 3G internet browsing (66.4%), with one hour of call on 3G (12.5%) and 22 hours of standby (11%) = 100%
A battery life issue is a problem where the drain is really out of spec either during usage or standby or both. For example, multi-% per minute drain during usage or a 10% drain per hour during standby is problematic. Browsing the internet on 3G during one hour and losing 16-17% is not.

davidch tips (reset+full discharge recharge):
Go through these steps to address the battery after updating to iOS 5.0.1:
1. Reset all settings (settings app-> general-> reset)
2. Go through initial setup steps (lang, wifi, siri, enable location, etc) and choose setup as new phone (don't worry your apps, data, contacts, mail will still be there). Do NOT restore from iCloud or iTunes (It can copy back corrupt settings)
3. Turn off system location services timezone and iAd
4. Fully discharge battery (tilll it shuts off with the spinning wheel)
5. Fully recharge battery (overnight if possible)
In my experience this improves the Standby battery drain issue significantly in most cases. It reduces drain from 2-4% or more per hr to 0.5% or less. It has worked for many, many users now. If it does not work after a few try's you may have a real battery or hardware issue and should contact Apple. Good Luck!
ram130's variant of davidch i.e. additional steps:
Now using davidch original steps and attaching the tweaks I made to get me more usage. As shown on page 29.

4. Fully discharge battery (till it shuts off with the spinning wheel)
5. Fully recharge battery (overnight if possible)
6. Disable Siri 'Raise To Speak' and REBOOT *( if possible use another camera to verify the infrared is off after the reboot).
7. Set emails, icloud and calendars to fetch. ** test. Mines on hourly.
8. If your in a no signal and your phone is saying "Searching..." even after 10mins, reboot while in that area and after 1-2min it should say "No Service". This mainly applies to Verizon customers and improve battery life in these areas.
9. *optional* Goto Settings > General > Network and you will see "Hotspot.." loading something, wait a few seconds and it should say "setup personal hotspot" then exit out.
* I notice a great improvement after disabling this and rebooting. This increased my "screen on" usage or at least helped it. Make the change.
** I have not tested push yet to narrow down the drain but I had this change on my phone. I believe exchange push is responsible for some stand by drain. As for icloud, haven't notice much of a difference. Just try it for a day. My email still came in fast most times. Again still testing, will report back on these..
buxbuster tips(wifi sync, iCloud):
These are my own tested workarounds that worked for my iPhone 4S and seemed to have worked for others as well :
Workaround number 1. Deselect wifi-sync in iTunes and press sync.
If that doesn't work try :
Workaround number 2 : Remove iCloud, reset network settings. ( I guess this won't work for you since you don't have it enabled ).
If both workarounds fail, you can always try to completely wipe your phone. That also solved some of the cases out there.
rolandomerida tips - i.e. buxbuster and additional steps:
Finally, I solved the syncing error loop. My contacts are syncing flawessly again between my devices and iCloud, and yes, the battery stopped draining, which is the main topic here.
I followed instructions from buxbuster (check his workaround a few pages up!) and an additional BIG step to restore contacts and syncing, as seen in a MacRumors forum.
This is what I did:
1. Make a backup of your Address Book, using the vCard option (or both, it doesn't hurt). Save it for later.
2. In your iPhone, delete iCloud account. When it asks, accept both: delete AND delete from my iPhone.
3. Reset network settings. The iPhone will restart, then will ask you to unlock the SIM card.
4.Turn Wi-Fi on.
5. Add the iCloud account again.
That's for Buxbuster's workaround. For some, it might work just like that. My iPhone repopulated from iCloud after step 5, but I still had that "server error" on iCloud. I had to do some extra steps, since my Mac was not syncing to iCloud and couldn't edit anything on my Mac or iCloud. Syncing back had to be fixed, too. If not, the syncing loop would continue from my iPhone, and the battery would drain awfully again.
1. In System Preferences -> iCloud, I turned Contacts off. I chose "keep on My Mac" those contacts, but I got an empty Address Book after a while. And a few minutes later, iCloud contacts were empty and my iPhone also. It is scary at first! Now, before importing that vCard backup...
2. Turn Wi-Fi off. This is important, since your contact-empty iCloud will attempt to wipe your Address Book from your Mac in seconds after importing.
3. Import your vCard backup to Address Book. Just drag it to your blank Address Book window; it asks if you want to import "x" number of cards. Of course, say yes.
4. Turn Wi-Fi on, and then iCloud contacts on again (System Preferences -> iCloud). It will offer to merge your newly populated Address Book with iCloud (which is empty at this point). It should upload every single contact to iCloud, and then to your iDevices. If not, a fifth step would be to import the vCard file to iCloud, but it shouldn't be necessary.
So, with iCloud syncing working correctly, there is no battery draining! Again, that was my particular issue.
I can't tell if this is the single answer to the widely spread battery draining problem, but it sure can be fixed with these workarounds, and yes, Apple should address the problem with a future update, for we affected customers don't need workarounds in the first place
This is the MacRumors discussion:

Miless tips (full 800mb release of 5.0.1 and sanitizing a restore):
As for 4S battery life. Try doing this,
1. Settings>Location Service ... disable all location services you do not need. In particularly Facebook because it drains the battery a lot.
Scroll down to the bottom at Settings>Location services>System Services ... Disable Setting Time zone, location based iAds, Diagnostic & Usage.
2. Settings>Notification>Calendar ... turn off the Notification Centre.
3. Settings>General>Reset ... do Reset All Settings. Doing this will not wipe out your iPhone. It will just Reset the network settings, location warning, keyboard dictionary, etc... but it will clear up some corrupted data there. Generally this will help.
Try these 3 steps first... if it still drains a lot, try the following,
4. Drain your battery down to 1%. Then charge it up using USB from PC ... not the charger. The charger output 1.0 A ( x 5V from USB ... you get 5W power). From PC, output is only 0.5A x 5V = 2.5W power. Charging is slower but trickle charge 4S helps the battery retain its charge better. I think it takes about 3-3.5 hours to charge full from USB/PC compared to slightly below 2 hours using iPhone charger.
If after doing the above still could not solve your battery issues (mine with iOS 5.0 was ok up to step 4, but not iOS 5.0.1).... plug you iPhone to a charger (any charger), from iPhone, access your iCloud ... set it up if you havent. Back up your iPhone data to iCloud. if you do not have enough storage (only 5GB is free), go to details and select the apps you need its data backup, choose only those you really need and leave those unnecessary ones out. Back up your camera roll to your PC/Mac manually as it could be too big to backup to iCloud.... once you have it setup, make sure you are on Wifi ... tap backup to iCloud from your iPhone. It will take a while if the file is huge.
Once backup to iCloud is completed, plug your iPhone to PC/Mac and launch iTunes 10.5.1 (make sure you have 10.5.1)
Click Restore. It will automatically initiate a download of iOS 5.0.1 ipsw for iPhone 4S. Wait for the whole process to finish, ie. download, restore software/firmware.
Once its done, do not set up your iPhone from iTunes. Set it up on your iPhone. Go through the selection. When prompted, select restore from iCloud (from your iphone backup earlier). Keep your iphone plugged into iTunes while restoring backup from iCloud. Because while restoring from iClouds, some data will be synced from iTunes if you plug in, e.g. music, video, etc... unless you bought these content from iTunes store. Apps will be downloaded from App Store from the cloud.
Once it's all done restored. Turn off your iPhone,.. and turn it on again.
Now, hopefully your battery wont be draining so fast anymore. Usually it wont after this. But you need to charge your battery at least 4-5 cycles to stabilize the charge on the battery. I dont know why... but battery life seems to get better and better for me after a few charge cycles after all the above work.
Good luck. Let us know if it works for you.
W. Raider tips (Sirii):
Bottom line for me of things that helped battery life are:
1. Turing off Siri and Rebooting the phone by holding the Home button and Top button down, ignoring the slider, until the phone shut down. (turn off Siri, reboot, and check top front of iPhone 4S against a lesser camera like the front-facing camera on an iPad2 - making sure the IR sensor is off)
2. Fully draining the battery, meaning using the phone until it shuts itself off from a drained battery and then recharging it to 100% about 4, maybe 5 times. I charged it both with a Mac and a wall charger.
Hope this is helpful!

jmm514 remarks (Twitter):
I may have found something. I had Twitter disabled in my notifications, but got a tweet today that popped up on my home screen. Didn't know I had this enabled. At the bottom of the Twitter notification settings is the home scrren toggle. Since disabling this, battery life seems better. Considering there is no setting for frequency of checking for tweets, it appears the phone is continually connecting to wifi to check for new tweets.
tmksnyder comments (notifications, corrupt data in iCloud):
For me, I found my iphone on wifi mysteriously connecting to my mac. I eventually narrowed it down to the Apple Move Trailers app which keeps a file in iCloud. The phone was trying to sync the file with the mac in the background even when the Movie Trailers app was closed (hitting the red x). Based on my macosx logs the iCloud process that was trying to sync was working directly between the phone and the mac without using itunes by connecting to an https address hosted on the phone. It was connecting every 3 minutes and failing (while phone was awake or awake during during a notification). I also found that iCloud control panel on OSX would error if I tried to delete the file. I fixed it by removing the App and doing a hard reset which stopped the sync. I probably could have turned off iCloud document sync in the phone but didn't think of that. My battery life has greatly improved while at home on wifi. I am now at 28 hrs standby, 2 hrs 20 minutes of usage, and 68% battery. It was ok before where I could get 20-30 hrs standby and 6 -8 hrs usage. My usage today was phone calls, 3g surfing, and music via bluetooth in the car.
I also found even with Itunes iMatch, if I mass updated tages, art work etc, it would hit the phone on wifi even in standby. I was amazed. Granted if I am not doing updates, Match won't hot the phone so this was a once in awhile event. I could drop my percentage by 5-10% in a matter of minutes when doing updates. I think a lot of our problems are background processes, associated with iCloud, notification, and apps. More features means more battery. I think the key thing is to keep track of what has recently been added or changed if battery life gets worse all of a sudden. It may be an app that was recently installed and if possible you may want to completely remove it and not just quit it.
With twitter, i think it uses push notifications so it doesn't need to be running and actively poll on the phone. For instance , if i quit the mail app, i still will get mail notifications and can swipe the message and load mail. Apple Push Notifications servics maintain the connection to the phone and there are likely pings or connection checks that occur for the service on an os level not an app level. This minimizes the load so there arent a bunch of apps all runing and constantly checking. The notification service , if it is contacted from twitter or another service with data, will check the settings you have registered to the with the apple push service and send the notification to your phone. No matter what, there is a drain with notifications. M hunch is once one application is configured to receive notifications, connection checking occurs betwen the push service and the phone so it knows where it is on the network. If it is implemented correctly, these checks arent frequent if you are still and more frequent as you move. The other drain is for when the noification hits and is processsed. If i get 9 emails over night, my screen just popped up for 20 seconds or so to process each message using battery. I would even think that just go from low power to turning n the screen uses more juice than if the device was already on and i get the message. On nights I get no notifications, I see a 3 or 4 percent drop. On nights with a number of notifications, i have seen up to a 10 percent drop. Besides notifications, wifi sync and icloud will poll on the local network and use up battery if the host computer is on and running itunes or trying to sync a data file that is corrupt (which i had with the apple movie trailers app causing my phone to drain). For me turning off wifi sync and remving a corrupt file in icloud solved my battery issues and I get over 24 hrs of standby with 6 to 9 hrs of use and this is with all the normal location services and push serivices turned on.
See http://developer.apple.com/library/mac/ipad/#documentation/NetworkingInternet/Co nceptual/RemoteNotificationsPG/ApplePushService/ApplePushService.html for more info. I think it has a good overview of how the notifications work.Well seems like that rumor of iOS 5.0.1 is finally gone the way of the dogs since developers got a beta of 5.1. So as stated earlier in the master discussion-> I suspect if you are filling up this thread with false post or creating a master set of links to various post that are unreliable you are wasting your time. Press is not going to touch the story due to poor or inaccurate sources which may be links from the master thread. This can include inaccurate information, combination of conflicting post or postings from users which may not own the device. Reputable press organizations have policies that require discloser and strict rules about what is a reliable source for a story. It is clear that many of the post in the master thread, which are links presented here are questionable.
Sorry to say that postings taken without any analysis of their totality have been propagated via various sites, for example sites such as http://www.2012federalbudget(dot)com. (Do not visit but I suspect that this is not the 2012 federal-budget site you would expect based on analysis of the records. There are plenty of sites like http://www.2012federalbudget(dot)com propagating questionable post in these threads.) One site for example in the discussion thread used a self signed certificate, the site had a log in to allow users to enter their OpenID. Seems many of these sites are pop and drop drupel configurations.
So remember this is how the really bad rumor of iOS 5.0.2 got started, the 5.1 memory leak issue, iCloud Issues, call quality, address book, etc.
Some of the postings have been very comical, I think the latest now is a dropbox issue. Seems that the length of the previous thread has resulted in various app engines of some proxy servers/tools reaching their limits.
So I would make sure to know the source of any information you link to. Make sure you avoid entering any information to outside links such as OpenID or Apple ID, these are big prize items for anyone with malicious intent. If you have issues and are a valid user contact APPLE CARE. (Note link is using McAfee Secure Short URL Service, and is https.)
http://mcaf.ee/ricdt
The original solution still represents a high level of success for users having any battery issues.
Install 5.0.1 on your iPhone 4s. Some users posting they are still using older versions, bad fake serial numbers, etc.
Make sure your device can run iOS 5.0.1 and is not altered.
Make sure you use a new Sim, not some cut down version which many users admit to doing. (Again, worth confirming what people are posting.)
Reset the device doing a hard reset and software reset.
Let battery drain and then charge for the full cycle, which is 24 hours.
I think you will find you will get the battery usage that APPLE has stated for the device.
Best of luck, stay safe and thanks -
hi guys
I feel like there is a problem with my iphone 5s. the battery life is really bad compared to my last iphone 5. I used to be able to charge my phone at the end of the day and would till have 40% or 50% left. now with this new iphone, it reaches down to 10% or simply dies by the time I get home at 6pm. I have turned off everything and i have searched google for all sorts of turn off tweaks so i could get the maximum battery life, but its still really awful. i listen to music for about 20 mins while on the underground train and later i might or might not get a text message or two and that is about it; the phone still yet loses all of its battery life while doing absolutely nothing. today i unplugged it from the charger and it suddenly went down to 99% right in front of my eyes.
i am going to the apple store on Tuesday to ask them if they could check it out. so my question is; have i missed something here or is everyone's phones are as such but not even one person is talking about it or they just don't care or embarrassed to talk about it, or what ????
btw my last iphone and this one are both 64GB black.
<Edited By Host>I have had the 5s for a week now, and I am having the same issue. I have restored the phone three times now, twice through iCloud backup and once through iTunes. I have shut down all functions of the phone as suggested, which is stupid, that's the whole point of having the iPhone, and anytime I do anything with the phone, the battery drains 5 - 10%, and its quick things like, checking email, then quickly closing that app, sending a couple text messages, and listening to one voice mail and I am down to 50 %. Not sure if it is ios7 or a 5s issue, all I know is last week I had a iPhone 4 that I had everything turned on all the time, I checked email constantly, text frequently, made calls and used the Internet and easily went three days without concern. Now I'm scared to check the time for fear of draining battery on the new phone. I also had the battery completely drain twice now and then charged it to 100%, and that has not helped either. I was much better off with my iphone 4 that I could at least use, and wish I had not traded it in at time of purchase. No point in having a phone that I have to disable all functionality and try not to use unless I know I am going to be near a outlet. So disappointed!!!! First time I have ever been mad enough to make a comment on a forum!

Hello, has anyone had problems with increase rate of battery life depletion? When I say increased rate I mean loosing maybe 80% in a 7 hour time frame while using the Iphone for nothing more than checking weather or stocks? This started after I went to the IOS 6.1.3. Before I could easily get 3 days out of the phone. Now I am wondering if it will hold the charge before I get home from work.
Hi imobl,
Thanks for your response, I forgot to add that the five 3uk sims we have in use, I have tried all of them none of them are recongnised non of them have pin codes, I even purchased four more sims Tmobile (original carrier) Vodaphone, 3 and giffgaff. -
A1281 is the battery i got for my 15inch MBP. Is the battery life only 2 - 3 hours for a new battery on this device.
This is from Apple.
2 to 3 hours seems very low.
what is teh standard or advertised spec for a 15 inch Macbook Pro with this battery.
I would like to know so that i can return it if this is not normal.
Its expensive so comments would be appreciated.I say it depends on your model? average usage is about 3-4 hours depending on what you use and how you use it. Adobe Flash player eats a lot of battery power so if you are on a web page and has flash player, likely that it's eating up battery because of it's power thirsty.
Also check your systems activity monitor. It could be possible that one of your program/apps did not close right and may be still running. So check for that and end the process if necessary.
If you have a backlight keyboard, in a broad daylight, it's not necessary to have it on.
I also suggest that you use it plugged in most of the time, and it's not going to hurt or damage the battery if you have it plugged in all the time. Only use on battery if you are going to places that has no access to the outlet. If you are at home, then keep it plugged in. Just keep in mind to fully drain the battery until it your MBP turns off on it's own. This is the calibration process so that you have the most accurate battery readings.
The standard for 2011 MBP is 7 hours on battery. Before that model is 10 hours, but i don't believe that previous models will last 10 hours. Last week I calibrated my battery readings from fully charged and it took 9 hours to completely drain out the battery (I have a 2011 model),
If you think it's not normal and that your battery doesn't meet your expectation then set up an appointment with the genius bar and have them test the battery. They will determine whether it is faulty or not. -
MBP 15" Retina Battery Life Problems
Hello all!
I recently got the highest end MBP 15" Retina and it runs AMAZINGLY fast, but the only problem I'm having with is the battery life.
For example, right now, at 100% charge, the predicted time is 4 hours and 35 minutes, but it's plummeting very quickly; I don't think I'll get more than 1 or 2 hours.
On the website, the average predicted battery life is almost 8 hours. I understand that the numbers on Apple's website may not be exact, but I feel like getting a quarter or even half of the advertised battery life suggests there is something wrong as well? o-o
I'm not doing anything intensive on my computer either; just simple web browsing and chatting on Skype.
I've searched the internet for solutions, and I've already tried resetting PRAM AND NVRAM settings, I've turned off Bluetooth, and checked off all of the Power Saver settings in Preferences.
My battery's condition is "Normal" since I recently purchased it.
I'm curious if anyone has a solution to this problem? (To give an idea of how fast the battery is draining, I started writing this post with 100% battery, and now it's at 98% several minutes later)
If anyone has any advice, it'd be greatly appreciated!
Thanks in advanced!puzzledsean wrote:
I'm not doing anything intensive on my computer either; just simple web browsing and chatting on Skype.
Skype is one of the most resource hungry application that one may use. It will drain the battery very quickly. When using it, connect your MBP to the power adapter.
Read the Apple hype regarding battery run time. The operative term is 'UP TO' not will achieve 8 hours run time. In the 'real world' conditions, battery run time will be determined by the number and type of applications you are using. If you are just text editing, you may very well get 8 hours from from the battery, but certainly not with Skype games or video.

Can someone at Apple please help me with iPhone 4s battery life?
I bought two iphone 4s 16gig's the day they were released from Sprint and am having horrible battery life. I love the phone and its features, but I have tried everything I have found in the discussion groups and in other forums online and am still getting terrible battery life from the 4s's.
For example, I charged my 4s when I got home last night and then once it was at 100% charge at bedtime, took it off my charger in order to use that same charger to charge my ipad overnight. This morning, the fully charged 4s had dropped to 45% battery life...without ANY use whatsover overnight...! I just asked my wife how her 4s is doing today and hers is down to 63% since this morning with very, very little usage. (She hardly ever uses any of the data features, etc., only makes phone calls).
Something really weird also happened to the battery life yesterday while I was flying home from Venezuela. I had charged my phone overnight and did not use it at all on the way to the airport, then turned it off on the plane from Maracaibo to Miami. When I arrived in Miami, I turned it on, checked my email, sent a few text messages and also some Heytell messages during my 1:45 minute layover before turning it off before getting on the plane. Our flight was delayed due to mechanical problems and I turned the phone one in order to show my seat mates how Siri works. When I turned it on, I was shocked to find the battery percentage had dropped to sixty some percent...!
I left T-Mobile after 8+ years as a very satisfied customer specifically to get the new 4s. Was running jailbroken 3gs on T-Mobile without any problem and much, much better battery life. Needless to say, I am very unhappy with what we are dealing with. I wish someone from Apple would at least tell us what is going on or simply replace our phones if it is a hardware issue.You need to check out some of the other threads on battery issues (but not the very long one) in this forum. There are a lot of suggestions from users who seems to solved the problem.
But you won't get any Apple input here, as this is a user-to-user forum and Apple usually doesn't respond to out posts. -
I have a mid-2012 Macbook air and I've noticed recently my battery life is horrible. I've read every single other thread about this issue but nothing really helped and even the most recent is from a couple of years ago. Obviously now it's 2015 and my macbook is running on Yosemite, so its not the battery issue that everyone seemed to have with Mavericks.
Just writing that small section I went from 73% to 68% and at the current 68% I only get an estimated 2 hours and 10 minutes remaining. I've also had only Safari running this whole time.
Option clicking the battery icon reveals that the condition is normal, as well as the power system report. It also has gone through only 441 cycles, no where near its 1000 cycle "limit" and its health is already down to 77%. While obviously the condition is normal and doesn't say I need to replace the battery I feel that I should, based off of everything else.Have macbook air from mid 2012 - I installed Yosemite November 2014 and since then I'm having problem with my battery - it has been draining super fast - 4hrs battery life now compared to earlier 8hrs.
I reinstalled Yosemite, didn’t help and then made a clean reinstallation of Yosemite about 5 days ago and there is still the same drain issue.
Thank you in advance!

Improving the 2013 Macbook Air i7 battery life
Hi
I've checked couple of topics related to this issue seems many people suffer from this problem, i7 8gb ram with 512gb ssd Macbook air has some issues with its battery life it reduced very quickly. I've applied some techniques -like smc reset,deleting launch daemons and agents- and have an improvement in battery performance. Now the point is, when i do the EtreCheck there are many kernel extensions displayed in the report. Is there any way to delete them and slightly improve the battery life?

Is there any other suggestions that you may offer ? Many thanksYou can use the new Activity Monitor to determine a unitless "Energy Impact" value:
You can also click the battery icon in your Mac's menu to reveal significant energy hogs (UPS is shown below):
Whereas Apple recently updated their apps to take advantage of Mavericks' energy saving algorithms, few other vendors have. I surmise the prominent "Energy Impact" hall of shame addition to the new Activity Monitor is Apple's subtle way of nudging them into compliance.
Google's plethora of invasive OS X system modifications is a popular reason for excessive battery drain. Google has yet to demonstrate the ability to develop efficient OS X apps, and one can only surmise they are not interested in doing so. If you elect to use Google Chrome or any other poorly implemented OS X programs, you must accept the detrimental effect they will have on performance and battery life.
If you no longer use a Blackberry, uninstall RIM's software. Be sure to follow its uninstallation instructions. -

No wifi and horrible battery life after iOS 7 install on iPhone 4S!
After the iOS 7 install on my iPhone 4S, my battery life is markedly worse and my phone will not connect to my home wifi. Every other device, including my wife's iPhone 5 and two iPad 2's, still connect perfectly. Please help. I wish I could go back to 6.1.3.
I've had issues since the upgrade too-messages wouldn't load, phone locked up and would turn off at random times. Then I noticed my data usage going up a ton in one day and checked and it wasn't connecting to my home wifi. Called tech support and they went through all the troubleshooting they could find and nothing helped. Had to go upgrade. You might try to reset your network settings, but that didn't help with mine
