Battery discharging despite being plugged in.

So I recently got a new battery the other day. I had the same problem with the old one as I am having with this one - although this is not the reason I exchanged the battery...
Even while the computer remains plugged in, my battery is discharging. It's very slow - losing 1% ever so often until it gets to 95% and then begins to recharge again.
I have noticed that it only does this while sleeping and not when the computer is shutdown (although the battery still does discharge if the computer is NOT plugged in, but I kinda expect that). Is this normal Macbook behaviour?
Thanks in advance.
D.A.M.O.N

This is not so much MacBook behavior as it is normal battery behavior. Batteries have a self discharge rate. That is what you are seeing. Even though the battery is not being used it's charge will slowly drop until it gets low enough for the charger to kick in.

Time capsule /time machine still gets lost despite being plugged in via Wan cable

Some days it works and others it don't.... why oh why do my Imac and time capsule fail to work together despite being wired together with the LAN cable.I have tried many options of forgetting /switching out the capsule and reintroducing it again. It may work for a while then up comes the message saying that the machine cannot be found! Urrgh! My system is an early 2009 Imac with osx 10.8.2 the time capsule is a 2tb 2nd generation. %0% of my hard drive is still available. No other faults are evident. Approx 1.65 tb remain available on the time machine that has been in situ since Oct 2011. Any ideas?
Ps.
Silly question possibly, but is there any real difference between time capsule and time machine?
I imagine the time machine to be the "guts" of the Time Capsule. Correct??
Thanks.

Don't blame you.. your experience is reflected in many many posts here.. and they multiplied when Mountain Lion came out.. which rather than fixing the still unresolved issues on Lion exacerbated them.. Apple meanwhile has used the ostrich solution.. which exposes some other parts. Or maybe waves them in your face.
We can clear up a few issues..
Time Machine is software on your computer.. it has nothing whatever to do with Time Capsule. A hardware that consists of an apple airport extreme router and a hard disk in a merged box.. with a couple of bit of ticky tacky to hold it together. It is a possible backup location for TM backups.. amongst many.
A Gen2 TC cannot be 2TB.. unless you replaced the disk.. please report the actual model number which is on the rubber foot.. A1xxx
At this point the issue is clearly a network bug. What where and why we are not sure.. nothing is a cure or work around.
There are crude methods.. a time clock electrical switch that shuts off the TC at midnight before it goes pumkin and awakens it a few min later.. or several hours.. not unheard of solution to adsl problems.. routers however should not need this treatment.
One very interesting post I have tracked.. had no problem with the TC as long as they used a USB drive plugged in.. the internal disk was the issue..
Some things help.
Mountain Lion does like the hard disk with space in the name.. but I think it is good to ensure all the names follow correct network standards.. ie short.. no spaces.. pure alphanumeric.
Is the TC in router or bridge mode?
Is the ML install clean or upgrade?
Are you using 5.6 utility
How to load 5.6 into ML.
1. Download 5.6 for Lion.
http://support.apple.com/kb/DL1482
Click to open the dmg but do not attempt to install the pkg.. it won't work anyway.
2. Download and install unpkg.
http://www.timdoug.com/unpkg/
Run unpkg on the desktop.. it is very simple.. drag the AirPortUtility56.pkg file over to unpkg.. and it will create a new directory of the same name on the desktop.. drill down.. applications utilities .. there lo and behold is Airport utility 5.6 .. drag it to your main utilities directory or just run it from current location.
You cannot uninstall 6.1 so don't try.. and you cannot or should not run them both at the same time.. so just ignore the toyland version.. the plastic hammer.. and start using 5.6.. a real tool.

My ipod Video won't switch on and always displays the message, "Please Wait Very Little Battery" despite being plugged into the charger.

Dear Apple Support Communities,
I am writing to inform you I have had my iPod for about 6 years now and it has slowly got to the stage where it no longer turns on. My iPod began freezing every now and then (for a few seconds now) and then this problem escalated to the stage where it began to freeze for days. I am now at the stage where it doesn't switch on at all, in fact everytime I try to switch on my iPod the following message appears on the screen, 'Please Wait, Very Little Battery' despite the fact that the iPod is currently being charged. I haven't used my iPod for months and was wondering if this promblem can be fixed or am I entitled to any upgrades.

Did you try to let it connected to USB for charging for a while before asking it anything. When the battery is deeply drained, it can occur that the iPod displays nothing for half an hour, just charging.
Also, make sure your PC gives sufficient power to the iPod for charging, I let mine once for six hours charging on my work's pc, and it didn't display "charged" message even after the 6H charge.
When an USB device is requiring more power than it can receive from the plug it is in, MacOSX advices it to user, It seems that Windows doesn't.

Why is my iPhone 4S stuck on a 1% battery charge, despite being charged for 30 hours?

I have had my iPhone 4S for barely ten months. In the past, I have had small problems that would either fix themselves or just stop occurring, such as freezing issues. But recently my phone was drained to a 1% and after realizing this I quickly plugged it into a car charger. About 15 minutes later, I noticed it had switched to an 100% battery charge. I blew it off and the next time I glanced at my phone it was back to 1%, so I turned it off thinking it would reset it and I would leave it to charge. I came back to the phone maybe 30 minutes later to power it up and it displayed the red sliver of battery with a lightning bolt underneath it. It stayed like this for a good while and eventually came on. Since then it has been stuck on this 1% battery charge. One last thing I noticed was that the bolt inside of the battery on the top right hand corner sometimes shows a plug, saying its fully charged. I'd rather not turn it off because I'm not sure it will come back on. What do you guys suggest I do?

I have this same issue... the phone was fine, then 3 days ago then I noticed it was draining itself whilst on charge. Now it charges to 1% and lasts all day on that unless I reboot, then it just says plug it in and wont reboot! I have had a 100% charge, but it drained down to 9% in under an hour and then stayed at 9% all day. This is obviously an issue, so why is Apple not sorting it out?
Also, these kind of comments (BELOW) are about as useful as, "is it plugged in?"
"diesel vdub Atlanta, GA
Basic troubleshooting from the User's Guide is reset, restart, restore.
Try each of these in order until the issue is resolved."
I have tried 3 cables, 2 wall chargers and 2 docks, so it has nothing to do with those. I have cleaned the connections, so it's not dirt. It isn't water damage as the phone has been nowhere near water.

IPhone 3G = Yahoo Messenger drains battery even while being plugged in

Yesterday, I was on Yahoo Messenger. My battery went to 20%. I plugged it int, and stayed on Yahoo. the Iphone 3G still drained the battery completely and shut off. Is this norma;? Can't the charger over power the system draining?

Some apps, especially when requiring constant Internet access require a lot of battery power as they keep the 3G/WiFi radios active constantly. Especially on older models, this will be much more noticeable.
If you aren't already, try charging from the mains adapter (USB ports can't supply as much power, so using more power than it can provide will drain the battery).

Droid 3 shows 7 hours of battery use despite being off and charging overnite.

I've recently experienced shortened battery life (Motorola Droid 3) and noticed that when I turn on the phone (after being charged while off) it shows that the battery has been running for 6,7 or 8 hours. Wouldn't that number reset after being charged and off? Not sure what to do next…battery, charger or phone ? Any thoughts appreciated.

phonz
I completely understand how important it is to make sure your battery usage time is displaying correctly. When you charge your phone, do you charge it back to 100% before you disconnect it from the charger? With the phone powered on, can you charge to 100%, disconnect from the charger, and check how long the time on battery says?

I am unable to charge my MBPro....charging light not on, despite being plugged in

I am unable to charge my MBPro. It is plugged in, but the L-type connector is not lighting up and seems loose......the computer is approx 1 1/2 yrs old...

I don't think it is the charger, as this is the 2nd time this has occurred within the last 1 1/2 yrs........we changed the charger already and it was only temporary solution....

My iPhone battery discharged. Won't recharge.

It appears my iPhone battery discharged. I plug it in to recharge it, and nothing happens. In the past it would start slowly and then go to full recharge. Any hints.

new cable, try different wall port, then possible make sure no dust is in the charging port

I’ve tried to update my i-Tunes version after the site suggested I should following my i-Pad Air being plugged into it for the first time. The update seemed successful but the program would not open at all despite switching off the PC and re-starting several times. I then tried wiping the original software from the computer and re-downloading from scratch. Each time I tried the download failed with a message saying “Service “Apple Mobile Device” failed to start. Verify that you have sufficient privileges to start system services” At this stage, the only way forward was to “abort” the download. This I have done now four times and the same thing happens. When I did finally manage to get an i-Tunes shortcut on my desktop, the program wouldn’t open saying: “i-Tunes was not installed correctly. Please re-install i-Tunes. Error 7 (Windows error 193)” Any ideas to resolve this?

Troubleshooting issues with iTunes for Windows updates

Brand new ipod nano will work when attached by cable either to a power adaptor or usb port but stops immediately when disconnected, despite being put on charge with different adaptors. Battery indicator remains constantly on lightning flas symbol and whit

My Brand New ipod nano (sold to me two days ago by Apple as replacement for previous ipod nano -15 months old and therefore out of warranty - which had suddenly stopped functioning altogether) will operate only when attached by cable to either power adapter, usb port on my laptop or when playing on a docking station. When detached, it stops playing and screen goes dark and it will not respond to any buttons, despite being charged several times for many hours on different chargers. The battery indicator stays on lightning flash symbol on white background and has only momentarily shown fully charged symbol once !
I am baffled as to why this new ipod has a similar problem to the old ipod.
Is there a virus out there which can have this effect and which I may have picked up on my Pc and have inadvertently transferred to both ipods when sync-ing ?
My PC has Norton anti-virus software.
Any suggestions , please ?

Sounds like the Nano has a faulty battery. You should be able to have Apple swap it out again for you at no cost.

Make sure the headphone jack is fully inserted. The jack should be touching the ipod body.

Nano: Only works when directly connected to USB despite being FULLY charged

Hello all! This is my first topic/thread so I'm unsure if this is the correct spot to post this so please let me know. My issue concerns my Nano 8GB inability to play once fully disconnected from the USB/computer. This past week i noticed after having added some music that my battery indicator was on empty even after being charged for hours; i've never had charging problems with my unit before so I decide to reconnect it and let it charge overnight but to no avail. Once i remove the ipod from the computer the upper righ hand batt indicator was still showing empty; one day though the batt indicator actually had some life showing a sliver of "red" as to let me know there was some charge but a very low one so i decided on reconnecting it for another evening. Keep in mnd that despite the indicator showing empty i was able to play music/movies for a few days straight with no problems leading me to believe that its charging system was fine but that some type of glitch or software error was to blame for the indicator showing nothing.
But suddenly while listening to music the next day the ipod stopped playing and showed me a warning screen "Connect To Power" via a yellow triangle exclamation symbol right next to the BIG BATTERY symbol u get in the middle of the screen, and then shut itself off. From this point on my Ipod has not regained its ability to play independently and is confined to being connected via USB @ all times if I want to enjoy any of its content. Basically it can't run on its own anymore, however when i plug it back to the USB all my music/movies are accesible through iTunes and play w/out problems. Even when I hit "safely remove hardware" and the ipod ends synchronizing with the computer but is still hooked up to the port it will work in my hand normally without issues as it always has. It even shows me the little battery indicator on the upper right side fully green w/ the usb symbol in the middle recognizing its still hooked up to the USB port while I listen to my media; but IT MUST BE CONNECTED via USB cable for it to do anything at all once its removed all bets are off and my ipod won't work.
Also you know how after one "safely remove drive E" your Ipod basically SNOOZES if connected but not in use, well the screen that pops up is the Battery Life Screen where the BIG BATTERY symbol I saw in the WARNING Screen tells u how much u got left. Well guess what mine says whenever plugged into the USB port: CHARGED with the indicator nice and full of GREEN. But again once i remove that USB cable the ipod goes black, tells me I need to "connect to Power" and won't turn on or play music or even let me reset it; its like my Ipod has become a Phetus being kept alive by its Umbilical Cord.
I don't know if I've explained myself clearly but honestly i've been trying to read up on this type of issue EVERYWHERE but I can't seem to find any other cases like this one. I mean if its the battery wouldn't the ipod be completely unable to work even while its plugged in to the computer? This is very bizarre
an seek all the help & expertise u guys have to offer. If theres something you don't quite get please let me know and i'll try to break it down further. Thanks and i anxiously await your responses...
RECAP
Nano small battery indicator showed it was empty despite being fully charged
Nano won't work unless plugged in via USB cable
Will work perfectly through Itunes and independently but must be plugged in
Battery Indicator Screen says battery fully charged
Once unplugged Warning Screen pops up automatically, stating "Connect To Power"
which shuts off the ipod.

Yes, once I 'safely remove from drive' the ipod works normally I can listen to my media, change settings and even reset it by pressing MENU+center button. During resetting it goes straight onto the screen showing the Apple logo and then retuns back to automatically synchronizing with the computer (since its still plugged in to the usb port) and i can go into itunes and play my media via laptop. What type of servicing are you referring to? Should I try buying a new battery or sending it to apple so they can figure it out?
Two things which happened yesterday which were sorta demoralizing:
1 After unplugging my ipod from USBport the screen would automatically go black, right after I would hit the PLAY button and would get the "Connect To Power" Warning screen but under very Low Backlight before shutting itself down again. You could hardly see it, but now it doesn't pop up at all or give me any type of warning just a BLACK screen, so the only way of getting the unit to do anything is via usb connection.
2. Also the day before I had fooled my ipod into being connected to the usb even though I was pulling the usb cable very slowly from underneath its adapter; sorta letting it touch the adapter but not really hooked up to it. Well I managed to get the cable off and my Ipod to work for less than 10 seconds but I was able to scroll down the Main and Playlist menus without any lag or lack of Backlight before it went out. I tried it once more and it didn't work plus I don;t see what the benefits of doing so would be @ this point. But having said that does anyone think it could be a simple battery issue or is this harddrive related? Again the Ipod only work swhen connected to my usb & tells me its fully charged, but once unplugged it goes completely blank...

Normal Battery Discharge?

I have and continue to have battery discharge issues with my Powerbook G4. I get conflicting answers from the Genius Bar as to whether what I am experiencing is normal or not normal.
After a 24 hour period of my laptop being shutdown and unplugged from AC power, my battery has a 15min/7% loss. In other words, when I replug in my computer to AC power and turn it on, my computer says that my previously fully charged battery is only 93% charged and needs 15 minutes of charge time. (plus, it takes longer than that 15 minutes to actually reach the 100% charged listing).
I just replaced my battery and the PMU has been reset.
Anyone have any ideas? This is an intermittent problem as sometimes the battery remains charged at 100% after sitting for 24 hours and other times it does not.
Thanks!

Loosing 7% charge in 24 hours is not normal if the PowerBook was shut down (but would be fine if it was sleeping).
Are you sure that the battery was at 100% charge when you turned off and disconnected the PowerBook? When using the PowerBook plugged in, the power manager allows for the charge to drop to 95% before charging again.
The top few percents of charge may be special and hard to measure accurately. I suggest that you repeat your test, but start from a medium charge like 60%. Does it loose 7% in this case, too?

My iPhone 4 is no longer recognised by my laptop, and no longer registers being plugged in to charge, even though it will charge slowly if plugged in and turned off. It's not a cable problem or a computer problem, as I've checked these.

Hey, over the past couple of days my iPhone 4 (GMS, Model A1332, EMC 380B - running on iOS 7.1.2) has begun inexplicably intermittently not recognizing being plugged in to charge or being connected to my laptop. As of today, it has complete stopped recognizing being plugged in to charge or connected to the laptop.
If I plug it in to charge, whilst it is on, nothing happens and the battery drains.
If I plug it in to charge and turn in off, it will charge very very slowly - though it will charge fully after a long time.
When I connect it to my laptop, nothing happens - it doesn't appear in iTunes, and it doesn't charge or recognize being connected to the laptop (there is no charging symbol, no noise from either phone or computer registering the connection as it usual did, or another sign of any connection between the devices, though, again, it will charge very slowly if turned off).
I've ruled out the possibility of it being a cable problem, by using a friend's cable and finding that didn't allow it to recognize being plugged into the wall to be charged either, or being plugged into the computer.
My friend's cable does work on their own iPhone (ie, when plugged into the wall with their cable, their iPhone acknowledges this and charges properly, and when plugged into my computer with their cable both my computer and their iPhone recognize the connection).
So, it's definitely a problem with my iPhone itself, but I don't know what.
As I say, it will charge very slowly, if it's switched off whilst it's plugged in, but it won't acknowledge being plugged in, and will only drain if it is turned on whilst being plugged in - and it will not recognize being connect to my computer.
Please help me figure out what is wrong with it, as this is beyond annoying and I'm literally banging my head against the wall - the iPhone is little over a year old.
Cheers.

Battery discharge: Lion 10.7.2 vs Snow Leopard 10.6.8

Has anyone noticed that Lion consumes more resources than Snow Leopard thus causing faster battery discharge?
YMMV, but it would be interesting to see of others can get similar results. Do you suppose Lion 7.3 will increase or decrease resource usage and what affect will it have on battery life?
I called Apple about the battery discharge issue on my 2 week old MacBook Pro with Lion 7.2. I was only getting about 1/2 of the 7.7 WIFI hours advertised. They gave me the usual "if depends" on WIFI, system settings, applications, etc., i.e. such things as cpu and memory load (paging/swapping=>disk i/o), other disk activity, and a few other things.
My large expenditure on the new MacBook spurred me to investigate what was going on using the Activity monitor. I configured my old MacBook Pro (mid 2009) and my new MacBook Pro (late 2011) with the same system preferences. I reset both the PRAM and SMC on both machines to maximize the battery charge (documented elsewhere).
Obviously, a direct hardware comparison would not be meaningful but when you look at the operating systems there is a significant difference between Snow Leopard OS X 10.6.8 and Lion OS X 10.7.2. Lion uses much more resources than Snow Leopard.
My Observations:
The first value I list is for OS X 10.6.8 and the second for OS X 10.7.2. I tried numerous other combinations but these nicely summarizes my results.
1) I started with only the Activity monitor, iTunes Helper, and Epson EEventmanager manager running, No WIFI or any other user processes
CPU % idle               : 98.75 vs 99.4 (i.e. both machines were literally idle)
No. of threads           : 179   vs 277 --> + 55%
Kernel threads           : 60    vs 82   --> +37%
Processes                : 41    vs 54   --> +32%
Wired Memory MB          : 480   vs 864 --> +80%
Active Memory MB         : 198   vs 407 --> +106%
Memory Used GB          : 0.808 vs 1.32 --> +63%
Percentage of 4 GB       : 20%   vs 33% --> +65%
Virtual Machine size GB : 96    vs 149 --> +55%
2) With WIFI and Safari added
CPU % usage              : 72.9 vs 91.02 (i.e. both machines were not very busy)
No. of threads           : 253 vs 376 --> +49%
Kernel threads           : 60   vs 82 --> +37%
Processes                : 51   vs 63 --> +24%
Wired Memory MB          : 669 vs 1007 --> +51%
Active Memory MB         : 600 vs 1190 --> +98%
Memory Used GB          : 1.57 vs 2.47 --> +57%
Percentage of 4 GB       : 39% vs 62% --> +59%
Virtual Machine size GB : 131 vs 191 --> +46%
Look especially at the percentage of memory used. In either case, I measured no paging nor swapping. But, as you can see, with the increase of memory used with Lion when WIFI and Safari were added you could quickly push the memory as more process are added and start paging and swapping to/from disk hence use more battery charge.
The increase in number of threads, processes, memory usage, virtual machine size, and WIFI activity would imply that Lion would have to consume more battery charge than Snow Leopard as you use more cpu/memory to chase more threads.
I looked at WIFI usage and it involves a lot of chatter between the computer and the internet. Over time a lot of packets are sent/received even when no data is being passed and would be a drain on the battery. There would be a greater drain when there is data passed because of the additional CPU and memory needed. But, in todays world, you cannot run without an ethernet or WIFI connection because of the dependency on the information/data on internet cloud.
Hardware:
