    I don't have it. It's my only one. Perhaps you want to send me N900 for free? lolll....

    I am on a 5530 and have the battery indicator problem.

    2 = 20
    1 = 10

    forgot if im correct but you can edit this file to change how the phone reads and translates the battery meter icon

    Battery capacity in percentages for battery level 6 (i.e - 6 bars) - 100 %

    That's why when we have 4 bars left, those 4 bars run out as fast as it did from 6 to 4 bars. Now if we change the percentage value, we could have a more accurate idea of battery remaining (ex. 3 bars - 50% and so on).

    However, the conclusion in that thread was:

    So does anybody know if a file like this exists? How do we edit it? I believe that thread was talking about the Private folder in C. I looked through it thoroughly and didn't find it. I did find keys.dat though.

    I have heard that Li-Ion batteries don't respond to conditioning, so I am not sure about this. Has anyone else tried this? Does it work? It would certainly be the easier method.

    +1 for finding that post i mentioned...

    i got thi from wikipedia

    Advantages

    A lithium-ion battery from a laptop computerWide variety of shapes and sizes efficiently fitting the devices they power.
    Much lighter than other energy-equivalent secondary batteries.[29]
    High open circuit voltage in comparison to aqueous batteries (such as lead acid, nickel-metal hydride and nickel-cadmium).[30] This is beneficial because it increases the amount of power that can be transferred at a lower rate of current.
    No memory effect.
    Self-discharge rate of approximately 5-10% per month, compared to over 30% per month in common nickel metal hydride batteries, approximately 1.25% per month for Low Self-Discharge NiMH batteries and 10% per month in nickel-cadmium batteries.[31] According to one manufacturer, lithium-ion cells (and, accordingly, "dumb" lithium-ion batteries) do not have any self-discharge in the usual meaning of this word.[22] What looks like a self-discharge in these batteries is a permanent loss of capacity (see Disadvantages). On the other hand, "smart" lithium-ion batteries do self-discharge, due to the drain of the built-in voltage monitoring circuit.

    Disadvantages
    -Shelf life
    Charging forms deposits inside the electrolyte that inhibit ion transport. Over time, the cell's capacity diminishes. The increase in internal resistance reduces the cell's ability to deliver current. This problem is more pronounced in high-current applications. The decrease means that older batteries do not charge as much as new ones (charging time required decreases proportionally).
    High charge levels and elevated temperatures (whether from charging or ambient air) hasten capacity loss.[32][33] Charging heat is caused by the carbon anode (typically replaced with lithium titanate which drastically reduces damage from charging, including expansion and other factors).[34]
    A unit that is full most of the time at 25 ░C (77 ░F) irreversibly loses approximately 20% capacity per year. Poor ventilation may increase temperatures, further shortening battery life. Loss rates vary by temperature: 6% loss at 0 ░C (32 ░F), 20% at 25 ░C (77 ░F), and 35% at 40 ░C (104 ░F). When stored at 40%ľ60% charge level, the capacity loss is reduced to 2%, 4%, and 15%, respectively.[35][citation needed]

    OK, tried to "Calibrate the battery" myself and it didn't change a thing. Still at 100% until near dead.

    I can't believe Nokia hasn't fixed this in the new firmware. Grrrrr. I did some more checking around and found one person who claims that unless we are using 100% genuine, SEALED-package batteries the indicator won't work. They said that most phones are being shipped with copy batteries, even though they have the hologram, because Nokia is certifying them or something. He managed to track down a sealed battery and it worked for him. (Sorry, can't remember source.)

    This sounds like too much work for a pretty doubtful result to me. I guess I'll just deal with it and carry an extra battery in my purse. So not pleased!

    Update: My battery problem is gone. I am indeed getting 3 bars (57%) and 2 bars (42%)!

    Problem: I've been messing around so much that I have no idea what fixed it. I will report back when my "investigation" is complete. *cue Dragnet theme song*

    Evidence below:

    Out of interest, is this "device status" window built into the phone, or is it an application/widget? If so, where did you get it?
