Gilco2: well due to camera problems I also bought galaxy s4 but that suffers battery life. Under half of the HTC One. So dilemma, keep HTC ONE or Galaxy S4 and hope problems will be fixed in Android 4.3. HTC One feels better overall. Some photos are good while majority are blurry. If hardware surely all would be blurry. Of course I also worry about camera lens now after someone pointed that out on XDA site.
The S4 doesn't suffer battery problems it suffers from apps being left on and syncing. Try turning off google now, location services,
Sorry to hijack thread but the S4 isn't known for its battery problems
