  • Battery backup power can show 100% but the actual capacity of the battery may be diminished due to age/use.  That is, instead of the normal 3 or 4 hours of memory backup it may now only give, say, 30 minutes but it will still show 100% charge when fully charged.

     

    REPLACEMENT
    You'll have to open the case (i.e., void any warranty you may have left) and replace the button-cell backup battery that is attached to the main board.  You need a fine (very-small-head) torx drive set (sorry, I don't know the exact head size).  There are at least four torx screws involved -- two external (above the camera lens) and two inside the main battery compartment.

     

    Here is a link to a direct replacement battery -- I'm including this mainly so you can see the picture of what the battery looks like:

    I have not actually replaced the 6515 backup battery but I've hunted info enough to know that it's not a simple pop-out, pop-in operation like the primary battery.  Also, soldering *may* be involved depending on how the battery is attached to the main board.

     

    This basically amounts to a 'non-user-replaceable' part and was a real design shortcoming on the part of HTC, the company that created this phone for HP.  HTC usually produces very good equipment/designs so the choice to hard-mount the backup battery baffles me -- maybe HP expects their users to replace phones more often than batteries.

     

    Good luck!
