Speed test for integer to string conversion on Android

gistfile1.java

long start = SystemClock.uptimeMillis();
for (int i = 0; i < 1000; i++) {
	String x = Integer.toString(i);
}
long total = SystemClock.uptimeMillis() - start;
Log.i("time", String.format("Total for toString is %d", total));

start = SystemClock.uptimeMillis();
for (int i = 0; i < 1000; i++) {
	String x = String.valueOf(i);
}
total = SystemClock.uptimeMillis() - start;
Log.i("time", String.format("Total for valueOf is %d", total));

Debugging this in the emulator with Android 2.1 got me the numbers 129 ms for toString and 162 ms for valueOf. Not much difference, but the difference speaks in toString's favor. Oh, and I removed the String.format("%d", i) sample but it took 51928 ms.
