    I have been having troubles with the phone not booting - sometimes dead, sometimes that loop between gray empty battery symbol followed by green battery and going back to gray and so on...

    I checked the battery voltage with the voltmeter and got a reading of 5.32 Volt

    Is that the problem ? Shoul the batteries not be at 3.7 V or 4.0 max ?

    Something wrong with the (external) chargers I am using ?

    Battery voltage is 5.32 Volt - something wrong ???-voltage.jpg

    What says the specs that are printed on the battery?
    You might load the battery with a resistor while measuring.

    It reads 3.7 V 6.11Wh
    Not sure if i understood your comment correctly - you mean the measuring with the multi-meter falsifies somehow ?

    I meant let flow some mA with jumping the battery with a resistor while measuring the voltage on the resistor.

    Thanks again - unfortunately I have no clue what it is that you are recommending...

    I do own that multimeter...but that's about it ;-)

    That multimeter, are you sure it's okay?
    For testing you could measure a alkaline battery with 1.5V ... with the multimeter's 20V range before using the 2V range.

    When I use the 2V range the reading is "1"...going back to 20V range the reading gets back to 5.3

    Has anyone tried the same with their battery ? Are you getting like 3.7 or 3.9 or maybe 4.0 max ?

    I meant to test your mulimeter with a alkaline 1.5V battery

    I measured some different brands of Li-Ion batteries with my multimeter: 3.7V to 3.9V

    Got it :-)

    Thanks !

    A new Duracel Alkaline MN1500 with 1.5V gives me a reading of 1,93 V

    So the multimeter is the issue...?

    Still having a hard time then to understand why the phone will boot repeatedly with one battery and go into that loop between gray and green battery with the others...

    I think so. Is reading of 1.93V with using the 2V or the 20V range?

    Sorry, can't help you with your primary issue.
    Maybe you'd open a new thread without to mention this battery voltage.
