I am going from an old polar batttery (1400mAh) to a new one. The 2000- mAh value was already shown in bnf the first time i ran it and it seems to be going down towards 1500 which would of course be correct.

By Battery stats I mean the info obtained when the command lshal|grep battery

So what i did was correct - unplugging the charger when the bnf showed SOC 100%?

What difference would it make to leave the cahrger connected until the green LED is shown?

As I am technically going from a lower capacity to a higher capacity BUT the phone had this higher capacity (2487 or whatever) stored already and I am now working down from that to the genuine capacity!! Don't know how this situation arose but I think that is the nature of the beast!!

**Additional - found this on page 82 of the battery mod thread "The N900 actually has a chip that can do this capacity measurement and tracking, but it's unused, and the OS shuts down before 6% level at which the chip updates/"learns" battery capacity, so it's stuck at 2048mAh on most N900s. - shadowjk"

Perhaps this 2048 is the value that my phone started with as "default".
