Battery fails to keep up with current drain

[Guest Argonaut]

My SGS2 works fine as a phone .. and battery works OK ... charges OK.

However if in the car and I use it as SatNav ... even though plugged in and charging teh current drain exceeds the charging so on a long drive .. phone drains to point it warns of low battery.

I installed battery monitor app to charge .. and when I plug in USB lead ..it does show AC Charging ... and as it is a 1.5A USB charger it should charge to Max it can take (i.e. as for AC adapter)

However it goes flat ...... I have no doubt just combination of screen being on and GPS ....

Is there any way round this, or just have to accept phone can't actually keep up with power loss when used as SatNav.
