The battery lasts in my normal case approximately 3 - 4 days, with excessive use of must for 4 - to be recharged 5 hours.
The loading of apps working properly both from your phone or from your PC. Small drawback: Not all Android apps are compatible with the phone, unfortunately, among which are also some top apps as KlickTel or Barcoo. Especially to Barcoo I have not found a viable alternative among the available apps in all previous experiments, the scan function was not working. Whether this is a general problem of the phone, or whether the cause lies with the apps, I can not judge.
The touch screen is satisfactory, incorrect entries when using the virtual keyboard are rare. Input assistance "Swype" is however used to. When wiping it occasionally unintended page views. In my model, I note that on the far right side sometimes has to be pressed repeatedly until the touch screen processes the input. Since these little quirks not occur permanently, they are for me, however - especially considering the mobile price - perfectly acceptable.
The structure of web pages on the Internet function to work in an acceptable speed. I have to compare it with an I-Phone 3GS and can not detect any significant differences in the side building. Pages with many embedded image files or videos you should however be avoided. About the Apps page layout still works much faster, but the functions are the way to achieve some pages restricted.
The integration of e-mail accounts and the retrieval of mail works without any problems. Opening mails with file attachments blocked the device - depending on the size of the Annex - but for quite a while. I spare myself the meantime and open such mails he prefers only at home on the PC.
Oh yes, you can make calls of course - and the good sound quality both on the phone and the remote party.
However, the only major stumbling block relates to the information of the cell phone to its user. To this end, there is an information bar at the top of the screen. On this a missed call is indicated by a symbol z. B.. Available updates for the apps are displayed using a shopping bag icon. You will download this shopping bag remains in the bar and there is still a symbol of the download added. Has the news app breaking news to report, there is also this one symbol. All icons that have appeared on the strip, stay there until you completely off the phone and comes back. This information bar is tiny and is so far for the generation reading glasses quite a problem. I have already repeatedly not following act at a missed call, simply because I did not recognize the symbol in volatile inspection.
Some alerts through the mobile phone, it shows this by an acoustic signal, so for incoming text messages or news on n-tv. Makes perfect sense, if then at each signal a cause would be determined. This is unfortunately not always the case. Such false alarms come with me consistently 1 - 2 x daily before.
Conclusion: Despite the small drawbacks I give a strong buy recommendation. The price-performance ratio is excellent.
Addendum: Meanwhile, I have the phone for about 10 months. Meanwhile, the small internal memory makes a negative impact - to install new apps, I have to delete the old one or the other app. This, even though I have moved all movable apps to the SD card. Larger Apps (> 1 MB) can no longer load up, which I'm not sure here whether this might be associated with the now somewhat outdated Android version. Otherwise, I'm still satisfied with the device, but wonder if I change to the Galaxy W, which, after all, has 4GB of internal memory (150 MB compared to the Mini) has to offer.
