Re: [Skunkworks] Mobile Battery Charge Issues
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. bernard -----Original Message----- From: Gakuru Alex Sent: 18/12/2009 9:04:03 am Subject: Re: [Skunkworks] Mobile Battery Charge Issues But does it really explain the initial problem presented by this thread i.e. same network different phone('s batteries)?

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.

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 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. Brian On Fri, Dec 18, 2009 at 10:49 AM, wesley kirinya <kiriinya2000@yahoo.com>wrote:

I think there is one thing thats hasn't been mentioned. The current rating of the battery something like this : Battery: 960 mAh battery. You cannot compare the different phone like that, look at the battery capacity if its a 650 mAh battery it gets consumed faster than a 1100mAh one. But the network plays a big part also, and safcom is the biggest culprit. You get static when calling a safcom number from other networks.
