Actually Wes - I have had the same symptom on lower end phones as well i.e. longer battery life on networks other than safaricom. Esp those in other countries.

Mmmhh, seems like you might have finally really nailed it. The higher end phones have 3G/Edge. Maybe that's why lower end phones don't seem to suffer from the issue.

So it's both a Network Ops and Mobile device issue?

o_O?

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)?
