Battery life on GPRS vs UMTS/HSDPA

[markyeungcy]

Hi all,

Could anyone clarify that running on UMTS/HSDPA data drains the battery faster than on GPRS/EDGE?

Personally, I do feel the difference. Pls correct me if I am wrong about this.


Cheers,


Mark

Hi Mark,

Although the manual says there is a difference and on paper UMTS does require more processing power and therefore battery usage than 2G (HSPDA more so again but it's only active when browsing on an HSDPA network) in real life use you will probably not be majorly effected.

It can also be down to the location you use the phone. If it's a weak UMTS signal then the phone will be working harder to 'decode' the UMTS signal or if you are near a location area boundry your phone might be switching between location area A and B and transmitting location update massages alot which in turn will use more battery again.

I tend to charge my phone overnight and not once have I ran out of battery - infact I don't think I've seen it bellow 60% and I'm connected to UMTS most of the time.
