Exactly what my display showed. I re-set the date/time and the warning has gone away in last 24 hrs, but ..... WTF

same thing happened to me

some of the indication
- time kept resetting, showing no time when i turn on the car (before the time was always behind, running slow)
- no angel eye when unlocking the car
- obvious recharge sign

dealer recharged it, but in a day same thing happened again, they changed battery under warranty.

My e92 m3 09 had the increased discharge warning, I did a current test on battery and the meter showed about 1 amp discharge. My car was not completely turning off?? Found to be I installed a lead acid battery which is wrong , dealer installed a gel battery. They also wiped my ecu(which I wasn't happy with because I lost my ess tune😡(so I have to reload it). They loaded up 2015 software into ecu. Now the battery problem is fixed. The car draws 9 amps for half an hour then drops down to about 1 amp for about half an hour then down to .08 amp.
Yep these cars take a while to stop battery draw. If you unlock car then close it again the timer starts over.

I cannot understand "the car is not driven enough" excuse to not replace the battery under warranty. The M3 sees the track about once a month, and I am here to tell you, it gets driven. All of mine have been replaced under warranty, however, on one occasion the SA made the remark, "well, we will do it this time." If the time ever comes when they flatly refuse, and the car is still under warranty, BMW just lost a customer. Not mad, just a business decision.

They told me the battery isn't covered, on my 2011 with 16k miles (still under factory warranty for 3 more months). I'm going to read the warranty booklet to see if i can prove otherwise.
