OK, well, I think my battery improvement post might have been riddled with a little too much excitement for the reason that the device finally lasted for over 24 hours without having to be recharged.

THe increase was considerable, but not as much as 100%.

I believe the increase in battery was due to maybe better reception, and to the battery going through its first charge cycles to reach maturity.

Nevertheless I am very happy with the increase in battery life, with moderate usage I used to have to recharge in the middle of the day. I can now go from morning to morning without holding back on my usage at all.

I've turned on my Touch Search again, I'll let you know if I notice any drain, I doubt I will. I apologize, I did not mean to put down your app, without any real proof.
I never thought it definitely was a direct cause, it just happened to be that my battery improved shortly after I turned it off.
