Nseries Battery Life & Applications
Hello All,
Which applications drain Nseries' battery faster? I always leave "CONTACTS & LOGS" applications running in the background, so I can fastly access them. Would this have big affect on my battery? Does this reduce the battery life?
I always "exit" from larger applications such as "Camera", "Games", if I don't use them.
What do you say guys? Nokia batteries are not cheap, so I don't want to ruin my battery in 6 months.
Are both "Contacts & Logs" Application very power hungery applications for the battery?
Thanx
Solved!
Go to Solution.

Contacts & Logs don't really consume much power. The power draining functions are
1. Poor 3g coverage so better to switch the phone from Dual Mode to GSM only
2. Bluetooth
3. Wlan and Wlan scanning when not required
4. Display backlight
You can also monitor the power requirements yourself by installing Energy Profiler. You can download it from here.

Thanks for your response, do you have any applications running in the background? Do you also keep "Contacts & Log" running, so you can access them fast? Why/Why not?
Thanks Again

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!

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 -
Battery life and Heating up problems
After updating to mavericks , it seems that my macbook pro is always heated and the battery life got shorter even if I'm not using any app... anyone could help me ?
Hello Jeskar,
It sounds like you are seeing a decrease in battery life after upgrading to Mavericks. I would start by resetting the computers SMC, and evaluating the issue for a bit to see how that worked;
Intel-based Macs: Resetting the System Management Controller (SMC)
http://support.apple.com/kb/HT3964
You may also have to use the Activity monitor to see if you have any run away applications.
OS X Mavericks: About the Battery Status Menu
http://support.apple.com/kb/HT5873
When one or more apps consume higher than average energy from the battery, the menu shows "Apps Using Significant Energy" with a corresponding list of those applications.
Some apps may use significant energy depending on what they are doing. This is normal. For example, if you are compressing video in iMovie, or playing a graphics-intensive game, the app may use a higher amount of energy than other apps. If you are trying to conserve battery power, quit apps listed in the significant energy section.
If you suspect that an app is appearing in the significant energy section because it is not functioning properly, try quitting and re-opening that app. If the symptom continues, open Activity Monitor from the Utilities folder to troubleshoot further. The Energy tab of Activity Monitor displays the Energy Impact of each open app based on a number of factors including CPU usage, network traffic, disk activity and more. The higher the number, the more impact an app has on battery power.
Thank you for using Apple Support Communities.
Cheers,

Only thing running on it is Chrome, and the battery life is only 3:38. Am I doing anything wrong?
It also depends upon what you are doing on Chrome. Video and flash will eat up battery life. You are probably doing nothing wrong.
You might open Activity Monitor and see what applications are taking a lot of CPU%. Make certain that you have selected 'All Processes".

I have the early 2011 release of the 17" MBP (8gig ram, 2.2ghz quad i7, 500 gig harddrive) and it seems like the battery life has just been cut inhalf. It lasts me about 3 and a half hours from just general use. Is my battery faulty? Really appriciate any feed back
That battery looks pretty good, capacity is really strong for so many charge cycles, but the voltage looks low, would expect it to be in the 11.5 to 12.5 volt range and you are showing 11.27 volts. A little low but not critical.
How have you been handling that battery with respect to discharge/charge? While Apple has a lot of material talking about periodic deep discharge to shutdown and charge as a means of calibrating the battery, in reality that does not calibrate the battery itself. That only serves to calibrate the charge reporting circuitry built in to Lithium-technology batteries. In fact, the Battery University, an independent group testing batteries, has shown that repeated deep discharge behavior significantly shortens Lithium battery lifetimes. The optimum balance of use (discharge) and line-connection seems to be around 50% discharge before charge. Deeper reduces cycle life very fast, lower discharge makes for a very high cycle life but why buy a portable?
Anyway, just some thoughts. Use of high intensity applications, including other operating systems, looks like it is degrading the charge time but the battery itself looks healthy.
Just keep using it, perhaps try not discharging below 50% for a while and see how it behaves for your. -
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:

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.

Hello everyone I come to you tonight with a question regarding my Macbook Pro's battery life.
This computer is fairly new, it was purchased in September of 2011. At the time I was getting the advertised 6-7 hour battery life.
As time goes on, I do understand that the battery, will wind down. As of right now, I'm at 147 battery cycles and my batters "hp" (whatever that means, I don't know how that's measured.) is at 95%.
So with that, I'm now only getting 3-3.5 hours of total battery life, with my bluetooth off, and I'm only doing minor web browsing, with no flash. I'm writing this, with the only other application open being iTunes, and my timer is at 3:35 minutes @ 97% battery. My keyboard backlight is off, and my screen is only on 3 dots of the total possible. (Sorry that's very poorly described, I'm not sure of the proper way to go about it.)
So I'm wondering, is there anything that I could or should do to fix this?
The specifications for my computer are as follows, for those interested.

i was very impressed when i saw the 7 hour battery life of the macbook 13 in the store . but after using the system it only lasted 3-4 hours completely , same was the case for windows 7 pro. all the other functions of my mac are working fine.I buyed the system pin packed in front of me.I questioned the retailer about this but he had no clue what was happenig which caused this.I think this has something to do with china as my mac has been assembled in china and designed by apple californiahttp://computershopper.com/laptops/reviews/apple-macbook-pro-13-inch-2011-versio n these are the specs and the review of the system.but remove the phenominal battery life from the pros.I'm new to apple so please also provide me a location where i can get apple support in Pakistan
The 7 hour battery life is maximum that can be expected with minimal drain, but 3-4 hours either means you are using it very, very hard or the battery is bad. OR the gauge needs calibration, see below.
Turn off WiFi if you are not using it, and dim the display to also save battery power. It also depends on the applications that you are using.
One months is awfully fast for you to lose that much battery time. If the laptop was new, then I would talk to the seller about an exchange, at least exchanging the battery.
Have you tried calibrating the battery? See
http://docs.info.apple.com/article.html?path=Mac/10.6/en/9036.html
for how. Please note, this only calibrates when the MBP charges the battery and resets the calibration of time or percentage of battery charge left. The lithium battery does not have a memory. -
Mid-2013 Macbook Air Battery Life has become awful-Not Mavericks related
I have a Mid-2013 Macbook Air that I bought in July. i5, 1.3 GHz, 8GB RAM, 500 GB SSD. I honestly thought that my horrible battery life was due to the recent upgrade to Mavericks (many MBAir users are having problems with 10.9), so I downgraded to 10.8.5 this AM. With my backlit keyboard off and the screen at a mid-level of brightness, I am barely getting 2hrs of battery life. Before I go make an appointment with the Apple Genius, I was wondering whether anyone has any suggestions. I saw other threads on this issue, but none of them seem to really help. Below is the EtreCheck file (there seems to be a lot of Symantec traffic, but I am not sure that is the cause). Also, I am also running "hidden" so I wonder if the constant location services are draining the battery. Again, any help would be greatly appreciated. Many thanks.

After Mavericks install, your "time remaining" WILL BE INACCURATE until you do a SMC reset in many case
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.
There is a HUGE distinction here about someone getting less batt. life in actuality .......or are they just reading the "time remaining" and using that as a true indicator which is certainly is not.
Ive seen 3 notebooks after SMC reset jump 4+ hours in "time remaining" and slowly climb after 3+ full charge cycles.
Until things settle down, nobody should trust what the 'time remaining' says. -
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!

No battery life after system upgrade
I've searched this forum and found a few notes about significant battery problems after Android upgrades. Immediately after upgrading my Droid X, my battery life went from more than 24 hours to about 4 hours. The battery is very hot and takes about 6 hours to charge. Clearly something is draining the battery. The Verizon tech folks declared it a faulty battery and are sending a new one. I am certain that's not the problem, especially since others have reported the same issue.
So I hoped to wipe the cache before having to do a factory reset -- it was suggested as a possible solution. I have found some instructions for wiping the cache, but I can't seem to get the instructions to work. I power off my Droid, then hold the home key. Nothing happens. So I can't get to the menu that gives the options mentioned. Can anyone help? I loved my Droid until this update... I really need my phone to work as I am self-employed. I am my own IT department!Hi dazzie,
I understand your discontent; I would be frustrated if my phone's battery drained for no apparent reason. Please run your phone in Safe Mode as recommended by Cody21 (thank you!). Safe Mode temporarily disables all applications that have been installed via the Android Market. Performing this troubleshooting step is necessary to determine whether a 3rd party application is the cause of an Operating System / Application issue.
I have checked my resources and I learned that similar battery issues have occurred with other devices upon a software upgrade due to third party applications that are not fully compatible with the upgrade Operating System and a Factory Reset has resolved most post upgrade issues. Please do a Factory Reset as this may resolve your concerns.
Please keep in mind that performing a hard reset will remove ALL data including the Google account, system data, application data, application settings, and downloaded applications. -
Battery life shows shorter time at 100% than before
I used to see over 2 days at full charge, but now I see 1 day 14 hours at most, any ideas of the issue? I have the latest possible update android 5. Maybe is the reason? Any calibration possible? Resetting some battery manager? Regards...
Hi edokkir,
Some things you can try to maximise the battery life:
Turn off GPS, Bluetooth, Wi-Fi and Mobile data when not using them
Put the phone on Stamina mode and/or Low batttery mode - these functions are under Settings > Power management.
Check the battery usage menu also under Settings > Power management to see which applications are draining the battery the most.
Lower the display brightness
Lock the screen when not using the phone
Turn off phone or put into Airplane mode when there is no network coverage in the area as the phone repeatedly scans for available networks - which consumes power.
If you are using a Live wallpaper - change to a wallpaper that isn't live as this increases battery usage
Hope these steps help! Keep us updated.

This may not be a 4G issue at all but I've read alot about 4G being the ax murderer of batteries so I thought I would start here:
I'm trying to find any other tips to get more battery life out of my new phone. I went from 24 hours of standby time on a 5 year old blackberry with moderate usage to about 5 hours of battery time on very light usage brand new LG Revolution. Below are my settings:

Unplugged at 5:30 am
Sent two text messages
8:23 am down to 2 battery bars

Priscilla,
I need your help. This Revolution battery is killing me ....Part of th ereason I went with this phone is you felt the bat life would be better than the thunderbolt. Wow I can't imagine what the Tbolt is like.
Any tips or help you can give me would be appreciated.
Here is my efforts thus far:

Hi Bulldog69,
Have you checked if you have Advanced Task Killer downloaded? If so, have you removed it? Was this successful in changing the results for the battery?
If you did not have Advanced Task Killer downloaded, there are applications out there that will tell you what is using your battery. It could be an application that is constantly running, it could be an application that is left running accidentally, etc. I recommend going to the Application Market and doing a search on the word "battery." This may help in determining the cause.
I did check my references and I am not showing that what you describe has been reported as a known issue.
Please post back with any results.
Best regards,
No I do not have any task killers as I heard they can be can cause more problems than they are good. I have checked apps and found nothing causing battery drain and my battery just started getting real bad in the last week without adding any new apps. -

Use BitTorrent sparsely : start manually, and Quit (from the menu) immediately when the download is ready.
If you do not need a torrent app, uninstall it.

Push Notifications and Battery Life
If I have push notifications enabled, but no applications that use push notifications, will my battery still be drained?
You probably won't notice or experience any significant change in battery life with Push access turned off vs leaving it on, but if you aren't using any applications that use push notifications, then turn it off. Not much different if you never use bluetooth. If you never use bluetooth or not very often, it is a good idea to leave bluetooth access off unless you are using it.
