2720 fold - battery life
My 2 month old Nokia 2720 Fold now has a battery life of about 2 days while making about 2 minutes of calls per day, reading and writing <5 SMS. I don't use camera, internet, MMS. Worst battery life of any Nokia I have had (several).
Bluetooth is on, because I use it for headset and calendar sync.
How can I improve battery life?
General guidelines to maximise Battery life given here ..BTW if the BT is on contineously then what life you are getting should be OK, I think (others may beg to differ....).

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,

Macbook Air mid-2012 battery life issues -- a possible culprit ?
Hi all,
I've posted and followed a thread regarding diminished battery life for the mid-2012 MBA, when Mountain Lion was released. I never could fix the problem, was contacted by Apple but that didn't solve anything either.
The troubles I was (and still am) having with my MBA were :
Battery life reduced by at least 33% when I upgraded to Mountain Lion from Lion, following a firmware update.
No change when I clean installed ML.
No change when I upgraded, and then clean installed Mavericks.
My battery, after 13 months of use, had its capacity reduced to 70-80%, and has now been stable for one year at 70-80% capacity. It now lasts approximately 3 to 4 hours, and has never lasted longer than 5 hours since I upgraded to ML, which was a few weeks after the laptop was purchased...
I've tried everything that was posted on the forums, SMC resets, etc. Now to the (maybe) interesting stuff.
I stumbled today on something interesting. I was researching my issue to see if people with the same laptop, that followed the same firmware upgrade path than I did had similar issues. Long story short, a forum post led me to something interesting, located at /System/Library/Extensions/IOPlatformPluginFamily.kext/Contents/Plugins/ACPI_SM C_PlatformPlugin.kext/Contents/Resources
DISCLAIMER Whatever you do, do not try to remove / move anything in this folder.
What is interesting is that my Macbook Air has the following identifier : MacBookAir5,2. However, in the above-mentioned folder, there is no MacBookAir5_2.plist, it stops at 4_2.plist and then goes on to MBP models. Now, the question that I have is could the fact that this plist is missing be related to my battery issues ? In the sense that without this file, the kernel does not know how to properly manage the power, read the battery status / thermal sensors ?
I would really love to fix this 2-year old issue that has been plaguing my laptop ever since I purchased it.
Cheers,
Hadrien

Edited to add a screenshot of the plists directory.I leave my LithiumIon battery plugged in when near an outlet. But I use it on battery down to 40% at least once a month.
Using Coconut battery (download from macupdate.com) you see my battery is just fine after 18 months: -
When restarting my macbook pro, all the options on the top right corner of the screen disappear ( battery life, Wifi, languages etc..) when i try to show them in system preferences once i click on network preferences the whole system preferences goes Not responding and i have to force quit it. the only way i found to bring them back is restarting my computer a number of times till they just come back alone. not sure what the problem is??? now i never shut down my computer cause i am worried i'll lose them again and for months i just put to sleep when i am done since nothing happens to them when its on sleep once i shut it down and turn it on again the same thing happens.
appreciate any answers...You sure you're in the /Users/username/Library/Preferences/ folder? If yes, then that's your issue. That plist controls the right-hand menu bar.
log into a newly created admin user account and see if the problem persists. Then, check its Preference folder for that plist file. -
My MacBook Pro is really hot and the fan is on constantly. It didn't use to do this, does anyone know why this is happening? I have a very short battery life, so I have to keep it plugged in probably more than I should.
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.

My mac pro is suddenly VERY hot and also the battery life is very low. I left my mac on charge all last night, and it only gave me 1.5hr battery life?
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.

Reduced Battery Life After 10.6.8 Update - a Solution!
After updating to the latest version of Snow Leopard on my MBA13", my battery life plummeted suddenly from 7-9 hours to 2-3 hours. Genius Bar people replaced the battery under warranty but that made zip difference.
Exploring further I found that the Dock was running the CPU almost constantly at 100% and the fan was going berserk. Kept the breakfast warm though :-). Tracing it further, Parallels (ver 6) was the culprit. I did the following:
1: Launched Parallels;
2: Clicked the Virtual Machine (VM) menu;
3: Went to the Options section;
4: Removed Parallels from the Dock (left my desktop icon for it alone) by unchecking the 'Show Windows Applications Folder in Dock';
5: Restarted the machine.
Result?
Dock usage of CPU back to normal, fan silent, breakfast cold, and battery life back to 7-9 hours. JOY!!!Did the problem persist with the latest version - ParallelsDesktop-parallels-en_US-6.0.12092.670880 - ? If so then you should report this to Parallels as there may be more things needing fixing to eliminate this problem completely.
Oh, and this info is from Kappy, not MacBookProHayden. -
Macbook Pro Retina battery life fix
My machine came with Mountain Lion 10.8.2 a few weeks ago. When battery was charged to 100%, I had about 2,5 hours of battery time remaining (as showed when clicking the battery icon on top of the screen). I did the procedure below and now I have between 5 and 7 hours. I'm yet to test the real life battery time.
Another user wrote that the problem is said to be created by a corrupt file created by Migration Assistant and that the file needed to be removed through the procedure below. Interestingly enough, I didn’t use Migration Assistant when setting up my machine (I think I opened Migration Assistant at one point just to check it out, but I didn’t use it to transfer any files or settings). Also, after doing the procedure, the file was still there, however with today’s date. Nevertheless it seems to have worked very well for me, so it may be a good idea to try the procedure even if you have never used Migration Assistant.
Before doing the procedure, I took a copy of the file in case I later would regret deleting it and want to restore it. Open Finder. While holding down the Alt key click on the Go menu and select Library (if you don’t hold down the Alt key, Library won’t show on the menu). From the Library folder, open the Preferences folder. Then copy (but in my opinion don’t remove) the file com.apple.desktop.plist to another place that you can remember. It might be a good idea not to delete this file directly from Finder, since after I had completed the procedure, the file was still to be found in the Preferences folder (with today’s date).
The procedure:
In this procedure, leave out all quote marks “ “
Open Terminal (by going to the Applications folder and from there the Utilities folder and from there opening Terminal).
On the keyboard type “cd ~/Library/Preferences/” and hit Enter.
Now type “rm com.apple.desktop.plist” and hit Enter again.
Finally, type “killall Dock” and hit Enter.
After doing this I restarted my machine and let the battery go down to 0 % in order to then charge it up to 100 %.
KristofferDid this work for you?
Why do all the reviews out there (MacWorld, Engadget, etc.) claim they have 7 hours and we all end up with 2-4 hours. I think all the media is focused on selling products for Apple and do no really do any testing of their own.
Shame that even the guy who sold me this laptop 4 days ago claimed that I should get 6-7 hours of battery life and all I have seen so far is 2 maybe 3 hours at most. -
Windows 7 shorter battery life, I think I found the cause!
I bought a new 2011 MBP 13" i5 last week with the intention of running Windows 7 x64 on it, only to find that the battery life was quite a bit lower than OSX. First of all, the 13" only has ONE Intel HD3000 graphics card, so don't bring up the inability to switch between two. I've been working on it for days trying to bring W7's battery life on par with OSX which I managed to do through power plans, disabling components I don't use such as Infrared, SD card, Bluetooth etc. I also disabled system sounds because I found that while Windows 7 does disable the sound card when not being used, it only does so after about a minute. So if you click a folder, the sound card powers up to make the click sound then stays powered for about a minute until turning off again. Every time you click a folder or whatever and it makes a sound, the card is going to power on for a minute. OSX disables its sound card after a few seconds, obviously saving more power than waiting 1 minute.
I have been using a program called BatteryBar which tells you the battery's real time discharge rate. It started off at about ~9500mW of power consumption with a fresh install of W7, and after my tweaking I got it down to about ~7900mW at idle which is pretty **** close to OSX's.
The Big Problem
After I got the consumption down to 7900mW at idle, all was fine and dandy. The problem arises when you put the system to sleep and then wake it up again, the consumption at idle won't go below 10,000mW!
After putting the system to sleep and waking it up, something is becoming a power hog and the total power consumption won't go below 10,000mW. That shaves about 2 hours off the battery compared to the previous 7900mW at idle, pretty much exactly what people have been reporting! It's not the backlit keyboard or the brightness, I have made sure of that. It doesn't appear to be the graphics card which I have set to the maximum power saving mode, and have even tried re-applying those settings after waking it up. I've tried disabling wifi and re-enabling it, make sure everything is set to power saving modes.. but it still won't go below 10,000mW until I reboot it.
If you reboot the system, the consumption goes back to the previous ~7900mW at idle, put it to sleep and wake it up and bam 10,000mW+ again. It's replicable every time. I am trying to figure out exactly which component is causing it... but it's not easy.Every review over the years by major sites (Ars, Anandtech, Computerworld) regarding Windows Vista and 7 on Apple MacBooks have all stated that battery life was reduced but no one did measurements.
Do you enable and use hibernation instead?
Also Intel has a new feature but one which I think Apple has been using under OS X.
Seems like anything is going to rely on the SMC firmware.
Macs do not have the same fan control and thermal sensor integration they have under Windows.
Similar case for graphic card performance.
So I think there are multiple issues and a few out of our hands. -
I just downloaded more then 2000 photo's from my NIKON camera into iPhoto. Shortly after that my battery life was depleted and so I plugged the computer back into power and after I opened iPhoto later, I could not find those photos anymore!! Help where are they? How can I retrieve them or are they lost???
Please help me!!!Do you see more photos, when you enable "Hidden Photos" in the "View" menu?
And that was afetr I took the connection with the NIKON out of my laptop.
Check, if you really imported into your iPhoto library - is the preference setting "Advanced > Importing: Copy items to the iPhoto Library" active? If not, connect your Nikon again - do you now see more photos?
If you imported into the iPhoto Library, check inside the package:
Select your iPhoto library in the Finder, ctrl-click it, use the command "Show Package Contents".
There will be a folder named "Masters" inside, with subfolders named by year - month - day. Look for the date you did the import and check, if the photos are inside.
If yes, copy this folder to a folder on your desktop to save the photos.
If not, search for a folder "Importing" inside the library. Is it there? Then copy these photos to a folder on the Desktop.
If you found your photos, backup and rebuild your library.
See Old Toad's post here: Rebuild iPhoto Version 11 -
IPhone 3GS with fw 3.1 – battery life gets even worse
I've made the so long attended upgrade to iPhone OS 3.1 and strangely battery life has got even worse than before. The phone is using 10-12% of the battery every hour of standby; usage counter grows by 35-40 minutes for every hour of standby. This happens with a clean install and just email setup (mobileme with push), with restore or partial restore. Turning push off only makes it slightly better.
I was wondring if I were the only one experiencing this...This is not even funny Jason... Really.
I now have a completely clean phone, installed anew through DFU. Now backups restored. Just setup my mobileme email on it and installed 2 (two) applications. iSip and DevInfo. Having push notifications and push email enabled, I'm loosing power at a rate of *8%/hour while in standby*.
Restoring my backup (which, by the way, is not an "option" but a rather important continuity pre-requisite) lets me have the same horrible battery performance. Turning push notifications and mail push off and booting the phone after that makes battery drain disappear (~1% every 1.5 hours).
Apple declares that using "Push" drains the battery 20% more. Even if this is an approximation, we're not even close to approximately 20% or 30% or even 40% increase. We're talking about battery drain growing 12-fold!
So pray try to help us – poor users – instead of repeating the link we've all seen thousands of times and that, frankly, has very little to do with how our iPhones perform in real life.
Thank you. -
IPhone 3gs Battery life with 3.1 firmware
Any news regarding battery life with firmware 3.1???? I have lost at a minimum 25% after upgrading from 3.0.1 to 3.1. Have reset....the device alone and with iTunes....Need help...
I originally posted this in the wrong discussion...
Since upgrading to 3.1, it looks like the biggest battery drain is due to using PUSH with my Exchange email. I can turn off PUSH, use FETCH (even over 30 minute polling intervals) and battery life is close to 24 hours on a charge. Turning on PUSH, but not using it for email (other than my .Mac account (MobileMe), decreases the life by a couple of hours, still well beyond the normal 10 hour work day.
Turning PUSH on for 3 Exchange folders (Inbox and 2 sub folders) results in a drastic reduction in battery life. It can use over 50% charge while on standby... over a 3 hour period. I've managed this to an acceptable (8-12 hours, depending on phone calls) by limiting using Exchange rules to keep most important email to the Inbox and one sub-folder (I may eventually leave all important stuff to the Inbox) and move other stuff into different folders that I can still check on occasion.
Other PUSH activities, using apps like BeejiveIM, AP News, MLB.com, i.TV and even .Mac don't seem to affect the phones battery life too badly.
I'm wondering if Exchange w/PUSH is doing too much, besides listening for new mail and alerting on it. Could the process be simplified to only listen, alert, and mayby increment the count (not downloading headers or message bodies until one actually checks for messages... the iPhone still polls once you open a mail folder anyway). -
Fans at 6k killing battery life
Both fans on my mbp run around 6k, even at system idle (w/ CPU temp around 50C). Anyone know of a way to calm them down? Instead of eight hours of battery life, I'm getting about 3...
Apart from the suggestion from eww above, this might be caused by a runaway process. If it is only recent, have you made any changes to software/hardware?
In the Utilities folder is Activity Monitor and that will list any processes running which should give you an idea of how things are.
A lot of users have experienced problems with Flash plugins and if you visited a site recently that was not well-coded, that may start problems until you quit or (in some cases) Flash crashes. (There is a download - ClicktoFlash -- that may be helpful to control Flash and let it run only when you need it.) -
Bluetooth Keyboard Battery Life Indicator Not Working
I have a wireless Apple BT aluminum keyboard and have been having horrendous difficulty with it lately. Last time I changed out the batteries was last month, so I thought I would check and see what the battery life was on the current set. Seems that the keyboard is not correctly reporting battery life, because the Keyboard section in the Control Panel is displaying 100% green. I know that can't be true because I use the keyboard frequently and these batteries are at least a month old.
I have also been having severe disconnect problems as of late - to the point where I need to keep a USB keyboard handy. My keyboard connection drops every 5 minutes, usually for 2-3 minutes (and sometimes requiring a re-pair), then it will come back and repeat every keypress once it is reconnected.
Is this keyboard defective? Is there any way of finding out short of hauling my entire iMac & keyboard the 1 hr. North to the closest Genius Bar?
Thanks.Try deleting the Bluetooth preference file.
com.apple.Bluetooth.plist /Users/YourName/Library/Preferences. Drag that file from the Preferences folder to the Trash, empty the Trash and reboot.
As for the disconnect issue. Do you have your computer anywhere near a microwave oven? They can cause interference.
Also, try resetting the System Management Controller, instructions here:

BlackBerry Z10 Battery Life is VERY LOW!!!
Hi,
The battery life of my BlackBerry Z10 is very low. After a 100% charge it drains in less than 7 hours.
Is it normal for this device or something is wrong with my phone's battery?
I am always logged in to the following apps, 24x7, using 3G network:
1) Facebook
2) WhatsApp
3) Google Talk
4) 1 Official Mail Account (MS Exchange)
5) 2 Yahoo Mail Accounts (All folder sync is enabled)
6) LinkedIn
Any suggestions or tips??
Thanks,
AshishYou've got a lot of apps running at once and that will definitely contribute to your battery's performance. If you're getting 7 hours out of your battery with all those apps running, I'd say you're doing fairly well. You can try closing some of them but I suspect you use them all frequently and would rather keep them running.
Topping up your battery's charge throughout the day is not a bad idea. It's recommended that you charge your battery for at least 15 minutes each time you plug it in. You might want to try that. Just keep in mind that the battery in the Z10 is recognized as a very good battery; you wouldn't get 7 hours out of some other smartphones' batteries.
One more suggestion would be to jump over to the Q10. It has a smaller screen but its battery is nothing short of stellar.
Cheers.
