    Does this need to be done? Will a restore wipe out the battery stats of the previous firmware?

    I'm not sure, but it worked for me. I had lousy battery life when I got my ip5. Did the restore, and battery life improved greatly.

    What i meant was doing battery recalibration AFTER restore, and not whether a restore is advisable to improve battery :p

    Do the battery stats get wiped after a restore? Does anyone know?

    Battery stats as in the cycle count and stuff? Then No, those won't get wiped after restore.

    I don't think they will. The battery level is reported by the battery itself, the battery contains electronics that manage the battery, control charging etc. Through use, this usage is better reported to the OS as the electronics 'learn' your usage.

    Ah so I guess the correct question will be

    Will a restore clear away all that the iPhone has learnt with regards to usage patterns? Because after a restore the batt seems to be performing at levels right out of the box the first time
