Battery lasts longer than expected

I have this fine mobile phone for over 3 months after I sold my iPhone 3GS, and it can correctly judge now. First of all, the battery lasts longer than a few write here. While it is a bit on the usage plan, but even with a few short phone calls, write SMS and surf from and to over the WLAN to get to 7-8 days.
I have default GPS, WLAN, UMTS, BLUETOOTH, DATA TRANSMISSION disabled and screen brightness on medium, and the screen timeout to 15 seconds.
UMTS I on GPRS switched and change it only when I need it, as well as Wi-Fi, GPS, etc. What I do not need, I turn on the Energy Monitor Widget aus.Achtung: with deactivated DATA TRANSMISSION can receive MMS, which should be observed .But I get anyway no.
I think even if I surf from time to time over UMTS, at least 4 days of battery life would be in it.
As I said, just a little turn, when allowed braucht.Es also not home all day at the stove.
Furthermore, I have the ADW Launcher installed, everything indicates to me on the home key. About the free software "MyPhoneExplorer" it is even possible to synchronize your device with Outlook via WLAN or USB without having to use Google to make. As a market, there is the website Androidpit where you can pay for apps via Paypal or Click & Buy. The Standard Market accepted to time only credit card. But there are also a bunch of free apps.
So I can only recommend the mobile phone, the only downside, I found the display in sunlight. Since reading is pretty difficult.But well so that I can live when the sun shines in Germany ever :-)
And the festeingabaute battery also does not bother me, because I've never had a cell phone, where I had to replace the battery pack.
