I´M So tired, i can´t find solution for high power consumption!!!! - GSM-Forum

DREAMGSM · 03-20-2003, 12:13

I measured the power consumption and was about 430-440 mAmp, then i changed the pa, reflow ccont, change ccont, try more pa´s, change all bga, ... lot of components like capacitors , resistors... on microscope all seem right, no sulfate, no shorts, no break lines... i´m will turn crazy

the phone is a 3310 and a 3330... any idea?

HI,,

what capacitor you replaced ?
try to check all "big" capacitor which is connect to "VBATT"
and clean battery connector !
and aslo check VTX path !

or you can try give a resistor 22k or 68K from BSI to GND,
and use power supply give 4V to VB+ , and use wintesla to make TX outgoing power level at level 5, and see how is it current used, that 350~450 mA at level 5 is normal !

hi, i changed first capacitor from VBAT, now max is 400ma, normal more or less, but i have another question for you willy, if you can answer you will help me a lot, sometimes i find phones, 3310 and 8210 that consume 430-420 more or less, i changed pa and some solutions more as you said here days ago, but no result, there is courious thing as if you take the cables from external supply and don´t move them then the phone show 400-410 but if you move the cables up or down consume change quickly to 430-440 350... is no normal i supose and maybe indicates something that i can´t see and maybe so easy and simply, no cable problem because with good phone if you mave the cables consumption no change.

What do you thing about this?, strange problem, am i crazy? or what happen with ****ing Nokia phones, sometimes i want to crash nokia phones against the wall

Information allways will be appreciate mates thanks for your help,
sorry for english and best regards.
