Location services and battery life
I see this from the Apple site regarding reducing power consumption:
"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."
http://www.apple.com/batteries/iphone.html
I can read this advice two ways:
1. Turn off Location Services in the Settings when not using Location Services. As long as Location Services is turned on in Settings, you are using more of the battery.
or
2. I can leave Location Services on in the Settings without reducing battery life. It is only when I use an application that uses Location Services that battery life is reduced.
Which is it?
Either one. When you see the white/purple arrow on the top, an application you are using has enabled Location Services for itself. While the app is running in either the foreground or background, LS continues to run until the app is either closed or has been force closed through the multitask bar.
LS only uses battery life when it either picks the GPS or the cellular towers to continuously ping your location. But the LS doesn't use as much power as believed. It's actually a combination of things such as GPS and Internet and Music or GPS, Internet and Camera.
Most people keep the LS running as it does little harm to battery life. Some turn it off or turn off certain apps to protect their privacy as they are broadcasting on a social network their approximate location such as LOOPT to friends that you are in a restaurant.

Location Services and battery explanation!
Ok, so many of us are uncertain regarding leaving Location Services ON because of the battery life problem.
I will explain the issue here so there will be no more questions about this:
When enabling Location Services you authorize the usage of the GPS unit on your phone. Below the LS switch you will see other switches regarding the applications that were using the LS in the last 24H. So the question is: Does the LS drain battery when leaved ON but no apps are using it? The answer is NO!
When you use an application that has the option to get your location it will ask for your permission to use the Location Services, if you will deny it it will not use the GPS unit, and so no power will be given to the GPS to function. Try to think the Location Services as it's name says so: a Service: When an application needs GPS information, the service powers up the GPS unit, when no application needs the GPS it cuts the power off from the GPS unit.
Do not compare with the Bluetooth! When using bluetooth, to be always discoverable the BT chip needs to be powered up all the time.
Think this as a somehow "standby" mode, the Location Service is listening in the background for requests for the GPS unit, when needed it powers it up, when not it powers it down.
You shouldn't be noticing more than 1 or 2% drain because of this service being enabled, nothing noticeable.
So it's ok to leave the LS ON as long as the apps using it are not enabled to actively use the service.Either one. When you see the white/purple arrow on the top, an application you are using has enabled Location Services for itself. While the app is running in either the foreground or background, LS continues to run until the app is either closed or has been force closed through the multitask bar.
LS only uses battery life when it either picks the GPS or the cellular towers to continuously ping your location. But the LS doesn't use as much power as believed. It's actually a combination of things such as GPS and Internet and Music or GPS, Internet and Camera.

Mail-In Service and Battery Life
I recently sent my computer in to apple to get the superdrive replaced. before i sent it in i had an approximate battery life of one hour while running airport and at full screen brightness with safari, mail and AIM running. immediately after i got the computer back from the service center the battery life had dropped to about 30 mins under the same conditions. was there something at the service center that caused this disruption, and if so, would apple be accountable to replace it?
Hi carocker and Welcome to Discussions.
If your battery was already down to 1 hour it was already on its last legs and replacement was already imminent. I doubt you'll get anywhere with trying to hold Apple accountable. You could try a PMU reset…
1. If the computer is on, turn it off.
2. Reset the power manager by simultaneously pressing and then releasing Shift-Control-Option-Power on the keyboard. Do not press the fn (Function) key while using this combination of keystrokes.
3. Wait 5 seconds.
4. Press the Power button to restart the iBook.
followed by a full Calibration…
which may improve things a bit.
Best of luck,
Adrian

I disabled Location Services and now I want to enable.
I disabled Location Services but now I wish to enable it. Both Location Services and Find My Phone app cannot be highlighted. How can I restore Location Services once it has been turned off? Thanks!
Hello john r.from ma,
Thanks for using Apple Support Communities.

Turning Location Services on or off
You can turn Location Services on or off at Settings > Privacy > Location Services. You can turn Location Services on either during the Setup Assistant process or later through the Location Services setting. You can turn it off if you don't want to use this feature or to conserve battery life. You can individually control which apps and system services have access to Location Services data.
Settings > Privacy > Location Services
Settings > Privacy > Location Services > System Services
By enabling Location Services, location-based system services such as these will also be enabled:
Popular Near Me: Your iPhone will periodically send locations of where you have purchased or used Apps in an anonymous and encrypted form to Apple to improve a crowd-sourced database that may be used to offer geographically-relevant Apps.
Frequent Locations: Your iPhone will keep track of places you have recently been, as well as how often and when you visited them, in order to learn places that are significant to you. This data is kept solely on your device and won't be sent to Apple without your consent. It will be used to provide you with personalized services, such as predictive traffic routing.
Location-Based iAds: Your iPhone will send your location to Apple in order to provide you with geographically relevant iAds.
Best of luck,

I have a early 2011 Macbook pro 13 inch, I'm running Lion 10.7.4, and i want to upgrade to 10.8 Mountain Lion. Is it safe for my computer or are people experiencing problems with displays and Battery life?
Do Not post stuff about how Airplay doesnt work, because i dont have Apple TV and dont need to hear about it.If you have an external drive equal to or larger than your internal HD, clone your internal to it with either Carbon Copy Cloner or Super Duper. Test the clone to make sure it's bootable. Then upgrade either one. Try it out first.

How do I add my new iPhone4s to iCloud's "Find my iPhone"? I followed the iCloud instructions and turned on Macbook Pros' system prefs to "find my mac", turned on iPhone4s's "location services" and set up iCloud, etc. In the "Find my iphone" tab of my new iCloud account (on my Macbook Pro) my iPhone4s still won't show—but my macbook does show. I had my iPhone4s set up at the phone store (2 days ago) and It receives gmail, my contacts and calender entries, the weather, etc. I installed the "Find iPhone" app from iTunes on the iPhone4s, synched to iTunes, even reset the phone, but the only device that gets located is my Macbook Pro. I can send a "sound" message to my Mac (and the Mac recieves it) but unable to see the iPhone4s from my Mac, let alone send any message. Any suggestions to get the iPhone4s device to appear in iCloud?
Thank you in advance for your help.OK, I figured it out...I deleted the iCloud account off my iPhone (Settings, iCloud, Delete Account), and then added iCloud back in (Settings, iCloud, SignIn)....and then my email (iCloud) and "Find my phone" features worked! Nice!!!!

Firmware Upgrade and Battery Life?
Since the firmware upgrade on my Macbook in early February the fan appears to be running at full speed all the time and battery life is crap! Has anyone else noticed this? Is there a fix/workaround available please?
Sounds more like an app stuck processing that shouldn't be....does happen from time to time. Behing hot means it is constantly processing.
To fix:
Try a reboot (described below).
Think of it this way, the iPhone is more of a computer than a phone. It suffers from being a new OS and nobody can deny there are not bugs and memory leaks. The longer left running, the more things start to fail or slow down (I have had the iPhone since day one of original phone and I am just speaking from my experience). Thus I equate it to like when Windows95 came out...not sure of your age or if you remember those days...but back then it was a running joke of how many days you can keep Windows 95 running before you had to reboot. I am sorry to say but the iPhone is the same way right now (but getting better with a few hiccups back during the 2.0 release). So for me, I reboot daily when I leave in the morning and take it off the charger. By doing so I rarely see any lag or problems.
A reset/reboot is:
Go to Home Screen
Press and Hold Home Button
Keep holding and press and hold Lock Button
Keep holding Both
You will see Slide to Turn Off (Don't let go to slide, just keep holding)
The phone will turn off (in time, but screen will look like it has some white lines)
Keep Holding
When you see the Apple Logo, you can let go.
Turning off via the Slide to Turn off while good and fine to turn off, is more like the Sleep Mode on a computer. Thus any locked up issues in memory remain when you turn back on. A reboot as described is like doing a real Turn off and Turn On on a computer.
You may also wish to read this tread about reboots and odd application behavior.

Help! This new version of Lion is making me miserable. The fan runs constantly, the computer is hot and battery life has dropped to under 2 hours on a fully charged battery. I updated yesterday, nothing but misery today. Even running the mail program alone make the fan run like I have everything open. Using Pages, iPhoto, and iTunes simultaneously makes the computer blistering hot.Yesterday, I could use all three without any trouble. Any suggestions to either jettison 10.7.3 or how to fix without any expense? I haven't modified this computer at all, it is as it came from the box in August 2011: 2.3 GHz Intel Core i5, 4GB 1333 Mhz DDR3.
I updated to Lion 10.7.3 and started noticing my fans running on high all the time and my battery would drain 2-3x faster. I was going to take my computer into an Apple store until I found this thread. I did the SMC reset by shutting down my computer, plugging it in, and then pushing down shift+control+option while also pushing down the power button. Nothing happens on the screen and the computer did not turn on. I then released all the buttons at once after holding them down for 10 seconds.
After that, I simply turned my computer back on and everything seems to be working fine. The fans are not blasting anymore. I have a newer MacBook Pro where I can't access my batteries. The SMC reset may differ for other types of laptops. -

My Ipad screen is blank except for the service and battery symbols. Any ideas how I can fix this please?
Try restarting
Hold down the Sleep/Wake button and the home button together until the apple logo appears (ignore the ON/OFF slider) then let both buttons go and wait for phone to restart (no data will be lost). -
I bought the ipad air to be used for marine navigation and installed both garmin and inavx charts. Currently none of the charts including apple maps can identify my current location. The error message says to enable location services and disable airport which I have done, but none of these applications work.

I FORGOT MY IPAD4(wifi) password and it got disabled now how can i recover it?? By the way the wifi is of and the location services and find my ipad are enabled now what can i do to recover it???? PLZ HELP!!!
Entering your Wifi password will not - unless I'm missing something completely - disable your iPad. The only thing which will disable your iPad that I'm aware of is entering your passcode for iPad incorrectly multiple times.
If this is the case then please see: http://support.apple.com/kb/HT1212
If you have forgotten your password for your router the WPA or WPA2 key as it's also known as they you will need to log in to your Router and setup a new WPA(2) key.

I lost my iPad 3, using location services and know exactly where there device at. I called police, they show up at that house, owner denied he doesn't have it. I even show officers on my iPhone where the missing iPad at and send message, face time, etc. But officers said owner don't let's they go inside the house, they can't help me to recover it???!!!
Are officers doing enough or they didn't do it enough to help me recover my missing iPad?
Thanks...I don't think Apple's Find My [xxx] has been legally tested as constituing probable cause to issue a search warrant by the DA, so the cops can't go in without an invite. You'll need a good lawyer to go in and force new jurisprudence to occur. By which time, the iGadget will be long gone from the place.

MSE 7.4 Base Location Services and Context Aware Licences?
Hi! I have a question for MSE Base Location Services and Context Aware Licences. Do I need to add Base Location Services and Context Aware Licences in L-MSE-PAK or just enough Base Location Services Licences? What is the difference in these licenses?
I know that the Base Location Services license is determined by the number of access points, and Context Aware license is determined by the number of devices.
Please help me with this issue.OK, for example, a customer bought a Context Aware license. Can he activate it in MSE 7.4 or need to install MSE 7.3 with Context Aware license and then upgrade to MSE 7.4?

i lost my iphone 4 last night and its not reachable assuming someone took out the sim.. so can i or my network company track the iphone which is not reachable through assuming location services and find my phone apps are enabled?
No. Find My Phone is the only way to locate any lost iPhone. However, this requires that Find My Phone be turned on/activated before the phone was lost, and the phone must have an Internet connection. If your phone is turned off, does not have an Internet connection, or has been restored, there is no way to locate it.
