for poor batt. life - check batt. connector ok, ONLY 1 pin offset from the 4! adjust tx power levels if possible! ideal values given in manual & if hav access to rf tester, adjust co-efficients accordingly..... IF tx values low on tester, then change pa.... for switch off- clean batt. pads as mentioned & reflow ccont

My 8850 was in water!

I have on BAT pins 92 Ohm resistance. I search true +BAT wires and I think that is N101 in fault! Is this possible?
VIBRA chip is OK! I remove it and still 92 Ohm on +BAT pin!!

8850 work OK only battery life is aprox. 8 hours! (because 92 Ohms on BAT pins of course..)

Best regards,
