N8 Battery Level Bars very inaccurate

hi guys,
Is it just the unit that I got or are we looking here at much wider issue?
n8 has 7 bars reporting different battery levels. when I say "different" I mean really bizarre. I am not sure if you have noticed but in my n8, first bar on the top dissapears when battery level drops to 70%. in other words, top batery bar represents 30% of overall battery charge. now, the bottom battery bars represents just 10% of overall charge. so, 2 bottom bars equal to 20%, 1 bottom bar indicates 10% of overall charge. I am not sure if this is just me but I find this information very very misleading. why the battery indication cannot be configured in a way that represents as accurate level as possible? at the moment battery bars are not equal and one of them is a symbol of 30% and the other - opposite equals to just 10% of charge. This really looks like a fw issue. I am on 011.012
do you experience the same issue?
also, can the % battery level reported in the cloud when battery area is pressed be more granular? At the moment we are looking at 10% increments. any more accourate data would be much appreciated.
thank you

Just wondering why Nokia never even bother to fix battery status icon, they rather create an app called Battery Monitor to bypass this. What dont they just delete battery icon and replace it with Battery Monitor in update if it is that useless?
Battery Monitor worked great in Anna, but after updating to Belle, Battery Monitor widget keeps freezing at random %. Now I have no way of knowing precisely how much life left in my N8. It just died without any warning.

  • 5800XM - Battery Level incorrect reading and phone...

    After installing v40.0.005 firmware, I have noticed when the battery indicator shows 4 bars of charge, a phone lock-up occurs.
    I can not use the white key to bring up the app menu, and phone functionality is limited.  The level of system lock up varies each time, but I always have to correct the problem by restarting the phone.
    After powering down the phone, and powering back on again, the phone shows two (or sometimes one) charge bar.  
    I have tracked the issue, and the problem seems to happen during these conditions.  The phone is usually on standby at the time it malfunctions.
    I have already done a Hard Reboot (Red, Green, Camera, Power), but this doesn't seem to solve the problem.
    I don't know if there is some relation to the two events, but any assistance in troubleshooting this issue would be appreciated.
    Nokia N8

    Thanks for the replies but as I said in my initial post, I had the problem even after buying a travel adapter (I went to Poundland instead of Maplin ) and using the supplied US plug - the battery level was still 0% after 40 minutes plugged in.
    Things are OK now though - as I said above, I put the playbook into standby (by holding down the power button for a few seconds and then choosing the standby option from the menu that appeared) and then it started charging. Once it had got past the magic 20% it installed the software update and it seems to be behaving itself since then... There seem to be some other posts on this forum (although nothing turned up when I search google before) about the playbook getting into a confused state when the battery level is very low - especially with old versions of the OS software so I guess it might have been this same problem...

  • Inaccurate battery level

    Here and in other places, I have seen several complaints about lack of a correct battery level indicator. This seems to be the case with more than one phone model. Considering short battery life, it is a real problem that battery level cannot be checked with any accuracy. I sometimes have 7 bars when I turn off my 6220 classic, and 4 when I turn it on again after a short while. This shows that the firmware checks battery level very seldom or that the procedure has very little precision. Checking with PhoNetInfo or NSysInfo gives the same result. They seem to reflect the firmware's reading.
    It cannot be so difficult to make the firmware check more often. Why has this not been done?
    Is there no software that is capable of doing its own direct check?

    it's not difficult to have the software or firmware that check batt level more... pool more but:
    - The more you do, the more batt it's used... therefore shorten your batt life again.
    - The batt has IC chip built in, and the batt after you use a while capacity is less and less and your chip may malfunction, which may give you incorrect value and batt life shorts.
    Even if you turn off your phone it still used the battery as if you set alarm and turn off, it will turn on and sounds.
    This is a feature too that ppl want...
    Hope this helps

  • ACPI battery level stops updating

    Hello,
    I have a strange problem with battery level (displayed using xfce4-power-manager). At startup it updates but not very precisely (not percent by percent), after some minutes  it stops updating.
    I thought it was an xfce problem, so I installed xfce4-power-manager-git. But reading acpi status and getting /sys/class/power_supply/BAT0/ info reports same results as xfce. ACPI does not update battery level!
    Why acpi stops updating my battery level?
    I'm using kernel 3.15.10-1
    xfce4-power-manager-git
    xfce4-power-manager 1.4.1-1
    upower 0.99
    lah

    No one interested about this problem?
    Now, to get battery level I'm manually polling using a cron job executing acpi -V command...
    I've not yet found another solution to get battery level update working.
    I found another interesting point. When I resume from suspend battery level updates... Here are my logs when suspending / resuming

  • MBP June 09: Battery Level Drops from 100% to 99% while plugged in !

    Hi,
    I have noticed that the battery level (indicated in the menu bar) drops from 100% (after recharge) slowly to 99%, then 98% while the machine stays plugged in! I did not let it go further so I don't know if it would further discharge.
    I re-calibrated the battery and this is still the case.
    Does anybody know if this is normal ? I read on the web that this is due to Apple's battery charging algorithm ...
    Thanks for your responses!
    Cheers
    Rainer

    Rainer: Your MBP's charging system is designed so that once the battery has been fully charged, charging stops until the battery level falls below 93%. Then charging resumes. All batteries gradually lose charge as time goes by, without any power being drawn from them by usage. A typical notebook battery loses 0.5% to 1% of its charge per day, even when the machine is completely shut down or when the battery isn't in it (as might be the case for a spare battery). A MBP in normal sleep will lose 1-2% of its battery charge per hour, as some power is used to preserve the contents of RAM in that state. In Safe Sleep, the MBP is essentially shut down and no battery power is used at all, so the loss of charge is limited to the base 0.5%-1% per day.
    Under extremely heavy loads (high CPU/GPU usage with maximum screen brightness combined with bus-powered portable drive operation, for example), your MBP may need to draw some power from the battery even while AC power is being supplied. Prolonged use under such conditions could, in theory, completely drain the battery, in which case the CPU clock speed would be automatically reduced to limit power demand to what the AC adapter alone can supply. But the likelihood that you'll ever need to work your machine hard enough for long enough to reach that point is very small.

    Try:
    - Reset the iOS device. Nothing will be lost
    Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Then see if placing the iPod in airplane mode when in standby helps.
    - Reset all settings
    Go to Settings > General > Reset and tap Reset All Settings.
    All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
    - Restore from backup. See:

  • 10.5.2 doesn't fix UPS battery level display

    I was hoping this bug in Leopard would be squashed in 10.5.2. Nope!
    When I reboot, the battery level display in the Menu bar and Energy Saver Prefs Panel show an empty battery and 0% charge level even though my APC 1500 SmartUPS is fully (100%) charged. The only way to get the computer to recognize the charge level is to put the UPS through a test cycle which resets the USB connection to the computer and forces the computer to pick up the data properly.
    This worked properly in Tiger without having to recycle the UPS.
    Griff

    I'm getting the same issue, sits there at 0%
    This is a real pain because I have it set to auto shutdown when the batteries get to 20%. Any power blip causes an immediate shutdown.

    I have had the iphone 5 for 4 weeks now and the battery life is very very poor at first i thought it must just be how it is....was dissapointed tho from fully charged to flat in 4 hours with little use or going to bed and waking up with the battery life going down 17%!!! but then 1 day i charged it fully and it never went down for ages, over 24 hours and it still had 25% this lasted for about 4 days then all of a sudden back to been rubish, i sent it in to apple who returened it without doing a single thing (apart from scratched an dented the bottom!!) it was exactly the same ..poor.....but then last night i charged it took it off charge at 6pm (english time) and now at 00.42am the day after it still has 11%....clearly ther is a fault somewere!!! has anyone had the same experience or got any tips for me please?
    cheers, Danny

    Yes a lot of people are having this issue it's from the ios 6 update. Some users are reporting battery drains a lot after updating their device
    There have always been a lot of battery problems posted about in these forums following each and every iOS update.  Personally, I believe that the battery really isn't discharging any faster, it is just that the charging circuit is confused and needs to be reset. I always perform a setup as a new phone for major updates, for example iOS3 to iOS4, 4 to 5, 5 to 6, which should be a 'reset' for the charging system, but I do a simple update for point releases--6.0 to 6.0.1, etc.  I have never had a problem with battery performance when performing the full update as new, only when I did a 'normal' update for a point release.  If I perform an update with a restore from the old backup after a major update the battery problem did appear.
    After every iOS point update I always do a full reset--home and on/off buttons held down until the Apple appears--three or four times over the course of a couple of days.  I allow the phone to fully charge overnight every night.
    This has always resulted in 'normal' battery life after one or a few reset cycles.  By 'normal' I mean that a fully charged iPhone, with email and other notifications enabled and set to push, and no particular attention paid to battery conserving techniques, will discharge to about 89% over a 10 hour day.  If I make a few phone calls and surf the web a bit then the level has fell to 70% or so, but unless I heavily use my iPhone 5 it doesn't drop below that point.
    Prior to performing the resets the charge level would sometimes drop into the 50's or 60's or even lower in a few hours without using the iPhone.  This problem 'scenario' has happened with every iPhone I have ever owned and I've owned all but the original iPhone.
    As always, YMMV.  I make no claims as to its usability for anyone else.

  • Battery level when out of box + real autonomy

    Hi!!
    I just bought a New Ipad (3). When out of the box, the battery was only charged to 69%, is that normal? Right after I turned it on for the first time and set it up, the battery decreased to 64% after only 10 min. Do you think it has a problem?
    One more question: when it says "up to 10 hours" autonomy, does it mean I can stream for 10 hours (Netflix for exemple) ? Or is it more the average autonomy for an average us (web + some video + reading...etc)?
    How long can the battery last when streaming 100% of the time (such as Netflix) ? Same question for when watching movies that are on my ipad (no streaming) ?
    Thank you for your support.
    JM.

    The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
    Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
    How to Calibrate Your Mac, iPhone, or iPad Battery
    http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
    At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

  • 6500 slide False Battery Level Reading.

    Hi,
    Just wondering if anyone has had their battery level showing as full when it is actually very low.
    This started happening after I updated my phone to firmware v 8.30, but probably more relevant after discharging the battery fully (as recommended)to improve battery life.
    Thanks.

    I have a 6500 classic and the battery started doing the weird levels.
    Showed that the battery didn't need charging as said was full but when took it off the charger it said battery low.
    Would not charge even after being on the charger all night.
    Sometimes works in the car charger (needed one as battery doesn't even last 1 day at work since bought the phone) but after showing 3/4 full, get 1 call and then beeps at me to show about to go flat.
    Phone is only 1 year old.
    Ordered a new battery so will see how it goes when it comes in on Monday....

  • N97 mini battery level drops suddenly

    I've observed my N97 mini's battery level dropping abruptly from 4 bars to 1 bar (with low battery alarm). The phone's slightly more than a month old and using the latest 11.x.x firmware. Did a bit of googling, and found several suggestions on how to save battery (turn off everything 'smart' on ur phone). That's not the point anyways. I need to find out why the battery level drops suddenly (like what happens when ur battery's dying out), and *not* why the battery lasts X hrs. I'm not sure about this, but I think this mostly happens when the battery level is slightly below max, and I use any app that needs the GPS functionality. But then, there doesn't seem to be any problem with the GPS hardware in the phone, 'coz it usually gets a GPS lock in less than a minute (mostly within seconds). Could it be related to the algo used to show the battery level, or is it that its my battery that's faulty? Any others out there having the same problem?

    It's understandable that the batterymeter is not linear (atleast the charge/discharge rates are not). But what bugs me are those sudden erratic drops within minutes (a couple of minutes at times). Anyone who has spent a few days with a dying (rechargeable) battery would know what I'm talking about. It's not a good feeling when u r away from a charge source, and you decide to use one of those power hungry things (like Wifi/GPS) thinking you still have sufficient juice left...and then bam! ... the low battery warning! you just switch off everything, and hope that it lasts till you reach the next oasis. I guess I'd have to analyze this a bit more to understand if its some specific app that causes such behaviour (as mentioned in my original post, i doubt the GPS apps currently). If it happens too often, and even with 'normal' voice+text kind of usage scenarios, its time see Nokia Care I guess. The reason for this post is to know if this behaviour is observed by other N97 mini users as well..then I know there's no point in taking it to Nokia Care.

  • Volume level bar no longer displays

    I used to have a volume level bar. Every once in a blue moon in reappears but very rarely. Whats the deal?

    Hi,
    If you have volume up and down keys on the keyboard then give try those keys and see what happens.
    You might also try unchecking hide inactive task bar icons depending on the system that you are using.

    Hi azuzeno, welcome to the forums and happy holidays,
    About Batteries. http://www.apple.com/batteries/
    From //www.apple.com/batteries/notebooks.html
    "Battery Lifespan For Apple notebooks with removable batteries — such as previous generation MacBook and MacBook Pro computers — a properly maintained battery is designed to retain up to 80% of its original capacity at 300 full charge and discharge cycles. You may choose to replace your battery when it no longer holds sufficient charge to meet your needs.
    Your battery info state "Cycle count: 262" So your pretty close to the 300 cycle limit. Just like an older car, old batteries can behave erratically. It's time to buy a new battery.

  • 100% to 65% Battery Level Decrease in Two Hours

    My question is: "Is anyone else seeing rapid battery level drop with iPhone since upgrading to IOS 8?"
    Since upgrading to IOS 8 on Wednesday the 17th, I have experienced RAPID battery level drop between charges.  I am now having to charge my iPhone 5s 32 GB half way through the morning, after lunch and when I get home.  If it weren't for my Mophie Jet Pack, a car charger and a charger at my desk, I wouldn't make it through the day.  Believe me, I have read every battery conservation tip out there. I have turned so many features/functions off that I'm really starting to wonder if IOS 8 is worth it for the iPhone 5S and below.  If I weren't faced with a daunting downgrade process, I would do it.  At least I used to be able to make it to 7 PM on IOS 7 before I put the phone on a charger or flipped on the Jet Pack.
    Using the new Battery Usage report under Settings > General > Usage > Battery Usage   I see that Calendar and Notes apps have taken the lion share of the battery charge over the past 24 hours, and there is a notation stating that the usage was "Low Signal" which I assume means that the phone was trying to do its thing with a poor cell phone signal.  At work, however, I am completely on wi-fi and not cell.  So this isn't very helpful.
    On the other hand, I have an iPad Mini with Retina and an iPad 3rd Gen that have been upgraded.  Neither of them have had any problems.  In fact the iPad 3rd Gen still has 92% charge after sitting in my backpack all weekend long (since being charged Friday morning).  So what I am seeing only seems to affect my iPhone.
    I do remember similar issues with the IOS 7 initial upgrade, which were resolved with subsequent patches/upgrades.

    Thanks Lawrence.  We use CommonTime mSuite to integrate our Lotus Notes with iPhone's Calendar, Contacts and email using the Exchange iPhone connector, and I am one of the administrators for mSuite.  I have deleted and re-added the Exchange account on my 5s running IOS 8 multiple times, and have done the same on an iPad Gen 3 and an iPad Mini.  All with the same results.  (The results are that email comes down, but calendar and contacts do not, and email will reload every so often.)  I've deleted the account on the mNotes server a couple of times as well, to no avail.  I have an old iPhone 4 still running IOS 7.1.2, and setting the exchange account up on it, immediately everything came down successfully from Lotus Notes onto the old iPhone.  This is definitely an IOS 8/CommonTime issue, and CommonTime has acknowledged that there is a problem, though they have as yet no fix.  The one good thing to come of this is I now know what was killing my battery. After 7 hours of use last night (regular use on Facebook and Feedly) my battery had only gone down to 83%. Other of our 46 users who have upgraded to IOS 8 have the same problem as I. 

  • The Levels bar into the red after normalization

    Sorry if this is a daft question, I am new to home recording and need to submit my audio via specific guidelines.  I'm trying to get into audiobook production.  I have a strong theatrical background but i don't know much about mastering audio so this has been challenging...
    In the raw file, the levels were primarily in green, occasionally in yellow.
    I used "match volume" to get my RMS to a certain level.  Then I used a limiter to set to -3 db.
    Now the file goes into the red.  According to Amplitude statistics.  there are 0 "possibly clipped samples" so why then do the levels keep going into Red?  I thought that was indicative of clipping?
    That's my first question, my second is does anyone know of any basic audio mastering classes for voiceover using Adobe Audition?  Less about how to edit audio, more about anatomy of audio files and the meaning of each of these parameters and how they relate to one another. 

    Thanks for your response.  I probably did a terrible job of explaining.
    I did originally try the "normalize" option and then the limiter but my RMS stats were too high to submit the audio book. They recommend normalizing peaks at -6db,  I found this video which states that you can normalize via RMS levels by match volume:  How to Normalize Audio Peak and RMS in Adobe Audition CS 5.5 Tutorial - Normalization - YouTube which I thought would at least bring that RMS number down so I was within their required range.  It did so all my amplitude specs meet their specs now but I'm just a little perplexed by the red in the level bar.
    This is all very new to me and I need to educated myself.  I don't even really understand the difference between normalization and compression and why one is favored over the other.  This is all really kind of over my head.  I think I can learn it but I need someone to explain it to my in layman's terms.
    When I do a raw recording, my Total RMS is always way over the recommended RMS the audiobook production company suggests a pre-mastered file should have.  Lowering  the gain makes the peak amplitude too low. That should be at -12 max while the RMS should be no greater than -28.  RMS is around -40.  So in a sorta related question, while recording, how do i lower my RMS without killing the peak amplitude.
