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? --- On Fri, 12/18/09, Bernard Mwagiru <bmwagiru@gmail.com> wrote: From: Bernard Mwagiru <bmwagiru@gmail.com> Subject: Re: [Skunkworks] Mobile Battery Charge Issues To: "Skunkworks Forum" <skunkworks@lists.my.co.ke> Date: Friday, December 18, 2009, 9:37 AM 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.

Hi;
Jared Koyier explained it all. Actually when a mobile handset is in idle
state (Powered and not being used) its is always doing 2 things,
1. Its keeps doing what is called Location Update. This means that if you
are driving and your fone on the dash board and your car radio ON sometimes
you
will hear your car radio being interrupted like there is an incoming
call. Actually the phone is doing Location update that the Network can tell
your new location as you move.
This consumes power.
2. The fone will always try to have the maximum signal all the time. This
means if the network coverage (Density) is bad your battery will be consumed
faster.
It uses power to do this. If you are near a BTS the phone uses less
power. Note that BTS power is emitted radially so the closer you are to
BTS the better as there is less attenuation. This can
be proved mathematically also. If you move to a place without network
at all and keep your phone on you will notice that the battery is consumed
faster. In the long run this
will also destroy the batter

The safaricom network has been very erratic over the last few weeks I
can say the least. at any one location there has been more signal
flactuation than usual. this am sure directly affects your mobiles
power usage, even at standby as it tries to negotiate for a higher
signal strength. this has the effect of reducing the battery standby
time.
