In addition, if the network mode is 3G, that too leads to more consumption. Actually, that was the main reason for the delay in 3GPP standardization. There's a great article here:
Energy Consumption Issues on Mobile Network Systems

Unfortunatley my IEEE account has just expired...but will send it once I renew....

It does explain.
The greater the subscriber density the greater the signalling required which leads to more power consumption,thus decreasing battery energy.Safaricom has greater sub density,followed by zain.

But does it really explain the initial problem presented by this
thread i.e. same network different phone('s batteries)?
