I read somewhere on Forum that if your mobile phone is running low on battery you can type in a 'message' and get up to 50% back from its membory. Can't find it anywhere. Must be an 'age' thing! Thanks in advance for any info.

Not quite right but here is the technical bits that will help you get a bit more from your battery

*3370# Activate Enhanced Full Rate Codec (EFR) - Your phone uses the best sound quality but talk time is reduced my approx. 5%

#3370# Deactivate Enhanced Full Rate Codec (EFR)

*#4720# Activate Half Rate Codec - Your phone uses a lower quality sound but you should gain approx 30% more Talk Time

*#4720# Deactivate Half Rate Codec
