My Nokia 9210 gives me usually just about 50 hours of standby time. I am experiencing it from the day I bought my 9210 which was in Sep, 2001.
On browsing through different sites I got the following info, which I dont understand
" Variation in operation times will occur depending on SIM card, network settings and usage. Talk time is reduced by 5 % if Enhanced Full Rate is active, and increased by up to 30 % if Half Rate is active. "
Pls guide what is this Enhanced Full Rate and Half Rate, and how can I make this Half rate active for my set.
