N82 10 hours Battery

My N82's battery started giving me problems and I replaced it with a new one bought from Nokia for 10kd (about 40 dollars) three days ago.
Now the problems are
1- It takes atleast 6 hours to recharge.
2- It doesn't say 'battery full' unless I turn my phone off and recharge it.
3- The first point of the battery lasts for about 8 hours*total idle. The rest last for about two hours or one 10 minutes phonecall.
There are absolutely no applications installed apart from whatsapp, the bluetooth is permanently off, and so is wifi (search and connection both off).
Should I take my battery back to Nokia centre for replacement? Or is it a general problem in all N82s? In that case I'll have to get another phone because 10 hours is just impossible to live with.

Certainly not normal behaviour. You could install Nokia Energy Profiler from here just to see what current is being consumed:

    If both computers were configured identically, then they would both lose the same amount of battery life with respect to the same starting configuration - comparing apple to apples. I don't know how much the added RAM, etc. would reduce battery life, but it would be less for both models.
    Battery life is a tricky subject because most mfgr.s like to suggest as long a life as possible, but often do so under a set of conditions that are not common to most users. Apple is no different. Their computers do have good battery life, however. But not likely as long as what is in the ads for the typical user.

  • How to use the new MacBook 13'' with Built-in 7-hour battery

    Hi,
    I just bought the new MacBook, it is my first Mac, and having the Built-in 7-hour battery I don't know if I can plug it in most of the times without doing any damage to the battery.
    On other portable computers, I just take the battery out and than plug it in and use it, but in this one that can not be done.
    So, what to do? Try to always drain and recharge fully, or it is no problem to plug it in when the battery is fully charged?
    I read that you should let it sleep(when it goes to sleep because it doesn't have battery)for 5 hours before charging it so it really drains. Is that really necessary?
    Also after it goes to sleep and I plug it in to charge, should I let it charge in Sleep Mode, or should I Shut it down and let it charge?
    What has been your experience with battery life? The first time I used it, it lasted for 4hours, is this normal and it will get better with 3 or 4 fully charges/draines?
    Thank you very much for your help.

    Hey guys, I understand your concern that you're not getting 7 hours out of your battery but let me put a couple things into perspective and also offer you some info from Apple's website that may or may not explain why you aren't getting the full 7 hrs.
    First mgb545, 5.5 hours is killer for laptop battery, but nonetheless you paid for it for the 7 hour battery so I don't fault you in any way for wanting what they said you would get.
    Second, the MacBook is Apple's "sub $1000" notebook. At first mention of that you think, "alright, it's under a thousand bucks!". It is, it's just $999...
    My point is that it's an advertising game. The MacBook can get +up to+ 7 hours on a single charge but not everybody is doing the same things or has the same configuration as when Apple was testing their machines. You might have a Time Machine HDD backing up (which I don't recommend nor do I think you guys do since you didn't mention it) or some other USB peripheral that takes power which would lower the battery's life. However, I think there is
    This is straight an easier explanation... This next blurb is the "fine print" from Apple's website right on their MacBook page about how they got 7 hrs.
    +"Testing conducted by Apple in October 2009 using preproduction 2.26GHz Intel Core 2 Duo-based MacBook units. Battery life depends on configuration and use. See www.apple.com/batteries for more information. The wireless productivity test measures battery life by wirelessly browsing various websites and editing text in a word processing document with display brightness set to 50%."+
    That all being said, I think or at least hope you'll find your answer there. For starters, it says "various websites". Who knows if those were basic HTML or Flash heavy sites or a combination of both? The other stipulation of this is brightness. Do you guys have your brightness at 50% or is it higher?
    Try this, I know the weekend just passed, but if you find that you have 7 hours where you don't need your laptop, leave it on, make sure it doesn't go to sleep or screen saver, play with it every so often, leave wi-fi on, make sure your brightness is at 50% and then see how long it lasts.
    One last thing, when you say you're getting 5.5 hrs out of your battery, how low are you letting it go to? I'm assuming when Apple says "a single charge" they mean it. So if you're getting 5.5hrs when it goes down to 8 or 10% you also need to factor in the extra time you might gain from that.
    Hope this help, let me know how your computers are set up, I'm curious to know if this will resolve or at least account for your lack of 7 hrs because me just recently got the 13" MBP and it doesn't get 7hrs either.

  • I have a MacBook Pro 13inch 2.4GHz (Intel Core 2 Duo, 4Gb RAM, 250Gb HDD, NVIDIA GeForce 320M graphics, SD card slot, up to 10 hour battery life)bought in October 2010 in the UK. The charger has stopped working. Which model and voltage do I need please?

    I have a MacBook Pro 13inch 2.4GHz (Intel Core 2 Duo, 4Gb RAM, 250Gb HDD, NVIDIA GeForce 320M graphics, SD card slot, up to 10 hour battery life) bought in October 2010. The charger has been playing up for a while now - the light going out but coming back on when I move the cable a bit - faulty connection it seems. It has now stopped working at all.
    Apple UK charge a whopping £65 for a replacement - and the reviews are AWFUL for it!
    I need to know which one I need - 45w, 60w and 80w are listed - can someone tell me please? If I'm going to pay this price I want to make sure I get the right one!
    Also, is a genuine Apple one available on Amazon UK, does anyone know please?
    Any help will be much appreciated.
    Meanwhile my battery is going down.....

    Thanks for that wjosten. Much appreciated.
    I've read here on Apple's site that the 85W version will work, as you say, and that it would run cooler with a 13" Macbook - I have a 13" MBP of course but assume this would be the same with mine. I wonder if running cooler is a good thing (it sounds as if it is) and it would be better for me to get the 85W version than the 60W one?
    Then I have to decide whether to pay the (extortionate as it seems to me, though I may be wrong) £65 from Apple (bearing in mind the rotten reviews here of the Apple product), or risk a cheaper alternative from Amazon UK, at around £20 (also with various rotten reviews)... Any suggestions? Please? :-)

  • Not getting 10 hour battery life.

    I remember reading it had to be at half the capacity of the uh, ..screen..light, lol. Am I missing something else? Mine's just a smidge below half, and it only has about a 4 and a half hour battery life. Are there other settings that I need to tone down that I'm not aware of? I bought my MBP this year.

    Hi
    Can you let me know how did you solve the battery problems. I was happy to have a mac with 8-9 hrs running time when compared to my earlier iBookG4 which gave 4.5 hrs till its late days.
    I am having a MBP that is just 1 month old and under use since a week.
    i am deeply worried when it shows 3.5 hrs after full charge. deeply disappointed.
    Do lend me some helping hand.

  • T420s - best 8 hours battery setup

    Hello Community,
    I just bough T420s 4GB RAm, 128SSD to my girlfriend and she is SO happy. The laptop is one sexy beast.
    However, I was surprized by the size of the main battery. It is tiny , like a chocolate bar So , I expected a tiny battery life as well. It looks like with WiFi and decent Screen brightness it is about 3+ hours.
    Charger is 65 watt and super small and it is not a problem to bring it around. Still, I was thinking what is the best way to extend battery life to 8 hours working day.
    My current idea:
    Buy 2 additional main batteries and 2 external batery chargers.
    Charge these 2 extra batteries every day Get them along with laptop.
    So at the end my girl friend will have: Laptop with 1 installed battery and 2 extra batteries.
    Assuming one battery gives 3.5 hours of active usage time it brings us to about 10 hours battery life.
    Batteries are super small a tiny , so bringing them along in her school bag (she is a student) should not be a problem.
    How do you see this setup? May be you have bettter ideas how to achieve 10 hours active usage time with less hassle?

    thinkfly,
    How do you use your laptop? I get between 3 and 4 hours on main 6 cell battery using WiFi and MS office. I barely can imagine adding smaller 3 cell battery and get additinoal 4 hours out of it. 
    I use WiFi and run 2 virtual machines, for coding and web browsing mainly. I don't do computing jobs on my T420s. Open your Power Manager and check the idle wattage. If your idle power consumption is more than 12 watts then you probably need to optimize your system e.g. check which applications are occupying your CPU.

  • Macbook's 7 Hour Battery not working

    My macbook pro is only a few days old and never lasts longer than 3 hours. I thought this was supposed to have a 7 hour battery? I have the backlights on the keys off as well. Why isn't holding a 7 hour charge?
    Thanks a lot.

    Apple should really address this a bit more to avoid confusion and panic (me included in panic). I had the same question... Anandtech says he got 6 hrs from his new macbook, and I never seem to get over 3 hours!! Anyways what I ended up doing was a bit of research on Apples Website, and they suggest recalibrating the battery first time around.
    http://support.apple.com/kb/HT1490
    I had gone through 3 charge cycles and with a 3 hr battery life all three times, I let the machine run all the way down into sleep, left it overnight in sleep mode and then charged it to full. As I am typing on the machine now... since past 30 mins battery life has gone down only 5% and for the FIRST time....as opposed to it being at 85% by now, and it shows 7 hrs remaining as opposed to 2 or 3 Woo hoo! ... I am going to let this run till the battery is depleted and post how long I got from the battery.
    Do the calibration.... its just the battery breaking in!!
    BTW I am testing with: 70% brightness, all widgets on, Safari and Mail open, iTunes playing mp3's at 30% volume, keyboard backlight on bluetooth off, push notifications on, Wireless 5Ghz on.

  • Ideal Settings for 7 hour Battery Life

    I just wanted to know what the ideal settings would be for a 15" MBP Mid 2009 Unibody to reach the 7 hour battery life as advertised.

    Apple states that the Better Battery Life setting was used, and +"The wireless productivity test measures battery life by wirelessly browsing various websites and editing text in a word processing document with display brightness set to 50%."+
    You can bet that the 'various websites' chosen were simple ones (no Flash animation, etc.). Also, 'editing text in a word processing document' with the autosave feature turned off will allow the HDD to spin down, saving power.
    So, what you'd need to do to get 7 hours on battery is set the brightness to 50% or less and do only +really simple+ tasks on your MBP. IMO, the 7 hr estimate isn't 'real world', it's marketing.

  • 10 hours battery time?

    Wonder how the battery time is calculated.... i have calibrated it twice and yet the battery can only last for about 5 hours only where I have only opened safari, microsoft word and excel...
    is there any problem with my battery?
    PS: i just bought it early of June 2010.

    Sharon Tan,
    Welcome to the forums.
    The 10-hour battery life for your MacBook Pro is Apple's claim, which is tested by 'light' web browsing, and low screen brightness.
    You say you have Safari opened up, are you watching any videos or playing any games? If so, the decrease in battery life may have something to do with Flash, which is a huge CPU drain and can drastically reduce battery life.
    Also, if you have the brightness of either your screen or keyboard turned way up, battery life will go down.

  • Raid Utility Message - 72-Hour Battery

    Anybody know anything new about Raid Message - I read there have been issues with this:
    Controller Reports RAID system 72-Hour Battery Reserve unavailable - etc. etc.
    Apparently this happens periodically when computer drains battery and recharges it. But I've been getting this message for 14 days now. I heard it takes a long time, but how long?
    Thanks,
    Jim

    I think I found it. I believe it is reporting past events every time you reboot wanting you to take action.
    The problem is with the UI on the RAID Utility. In the events pane you get the message about your battery being discharged posted on some date in the past. But how do you clear these events?
    Not obvious to me.
    If you horizontally scroll the events pane you will see a Clear button on the far right.
    Once you clear the events the status shows "Good" and I suspect it will not complain on the
    next reboot.

  • Replacement with new 10 hour battery?

    When it becomes necessary to replace the battery on my MacBook Pro which was purchased in Nov 2009, will it be possible to upgrade with the new 10 hour Macbook Pro battery system?

    Absolutely not, unfortunately. There is a short answer for this one
    1.) The main reason is that the new batteries in the notebooks aren't really ten hour batteries they just last ten hours because the new computers have different parts inside that work well, processors, graphics card. So since your not going to get those new parts, which is impossble to upgrade, you won't be able to
    2.) The new batteries probably have a different shap
    3.) Even if the batteries don't have a different shape Apple only replaces a part with the exact same part. They won't replace it with the new battery
    4.) IN the strange case that they did use the New battery if it had the Same size, then your chipsets are still different form the new model and you won't get the 10 hour battery, don't worry. The only weight to that 10 hour battery is marketing.
    to check the status of your battery(if you have the newest operating system Snow Leopard) hold down the option button and click on the batter to reveal the condition of your battery
    Battery conditions
    The battery condition tells you whether your battery is functioning normally and approximately how much charge it can hold.
    Here are the possible conditions:
    Normal: The battery is functioning normally.
    Replace Soon: The battery is functioning normally but holds less charge than it did when it was new.
    Replace Now: The battery is functioning normally but holds significantly less charge than it did when it was new. You can continue to use the battery until you replace it without harming your computer.
    Service Battery: The battery isn’t functioning normally, and you may or may not notice a change in its behavior or the amount of charge it holds. Have your computer checked by an Apple Authorized Service Provider (AASP). You can continue to use your battery before it’s checked without harming your computer.

  • Buy 60 watt hour battery for 63.5 watt hour mbp

    if I buy a 60 watt hour battery and put in a MacBook pro 2012 which have specification of 63.5 watt hour will there be any problem

    With that information in mind, I understand the limitations that you have to deal with.  If the physical size and the connection conforms to the MBP, in theory the reduced capacity should have a very minor affect on battery run time.  I certainly wish you the very best, but I think you can appreciate that there may be a possible performance issue.
    Ciao.

  • OS Mountain Lion 10.8.2 1-Hour Battery

    I recently updated to ML 10.8.2 from Snow Leopard on my 15" Late 2011 Macbook Pro, and twice now, it's done this thing where I open it up after it's been in sleep mode and the battery drains in about an hour, or an hour and a half. I've just been sitting here with a pages document, keynote, and firefox open, and it was at 50% in 30 minutes. That's NEVER how it normally acts. How do I fix this, this is ridiculous.

    All that suggests you have a runaway background process. These are often traced to three things:
    1) Running commercial anti-virus/internet security software. If you have it, dump it.
    2) Third-party backup software that comes with many name-brand external hard drives. All most users need is Time Machine.
    3) unsupported browser extensions or plug-ins.
    Yo can get a look at what processes are running. Here are the steps:
    1) Use the computer normally for several hours.
    2) Without restarting the computer, quit any applications you have opened,
    3) In Applications > Utilities find and launch Activity Monitor.
    4) If you have never used AM, you'll need to change one setting. There is a "Show" option with pull-down in the top of the AM window, like this:
    It's default is "My Processes." Change to "All Processes" and shown.
    5) Highlight the "%CPU" column to sort by processor useage.
    Watch the list for a few minutes (it changes as processes compete for resources). If you've quit apps you opened, no single process should take more than about 5 percent of the processes. If you see one or more taking over 10 percent, you probably found the cause of your overheating and short battery life.

  • A new Macbook Air only has 2 hours battery??

    I bought my 13" macbook air for less than two weeks. When I plug in the charger and have the battery charged to 100%, I found that there're only 2:xx remaining time. How can I fix the problem? Or do i need to have my battery charged for longer period of time (I'm didn't charge my battery for a long time when I first bought it, but only to 100% then unplug). 3 hours of working without charger is really short for me and I'm afraid that I cannot take it when I'm out. Isn't Apple said that the battery can persist for 10 hours? Why I cannot have this?
    Thanks!

  • 4 hour battery life surfing internet?

    am i missing something here or is this normal? i was expecting 4 hours when watching movies or doing more processor-heavy tasks.. but im getting around 4 hours, 5 at best, on the internet not at full brightness. this is the 2nd charge and i got it two days ago..
    any thoughts?

    Using gmail for instance forces the use of the nvidia graphicscard and the change back to intel is only made if you shut down the program, at best. Sometimes the release of the lock to nvidia doesn't work and you have to log out. This misuse of graphics card and together with flash on web pages makes the battery time very short indeed. Software update please Apple.
