HI,

First of all, I should remember that the Radio performance is provider and location dependent... (All my tests where made in PORTUGAL)...

Continuing the great work of ALLTHEWAY, P1Tater and many others concerned about battery life, GPS and overall radio performance, I would like to share to the community the tests I made with BattBench .NET (It measures battery life from how long your phone would last by running down the battery to a desired amount of percentage and testing it).

My test consists in two parts, first one is GPS testing and the second one is based on battery life test with BattBench .NET.

For testing, I let the PDA still in the exact same position, untouched during the testing process (no device use), with full battery charge. The device is set to GSM only (85-90% signal strength with Vodafone Portugal), and backlight is set to minimum. All the tests where made with Dutty’s 6.1 19199 after a soft reset and 2 minutes of waiting time.

For battery life testing, I have set BattBench.NET to drain 25% of the battery (from 100% to 75%) and then registered the estimated battery life gave by the software at the end of the test (test made once with each Radio).

For GPS testing, I let the PDA still in the exact same position, untouched during the testing process. I have used GpsTest 1.04 (yes, I totally agree with P1tater, in my opinion this soft is very simple and faster than GPStool). All the tests where made INDOOR, close to a window. With Dutty’s 6.1 19199 after a soft reset and 2 minutes of waiting time, then:

1º Turn on GPStest and wait 1 minute,

2º Registered the number of satellites found,

3º Wait another minute,

4º Registered the number of satellites found,

5º Registered the time spent until the device gets GPS Fix.

GPS TEST RESULTS:

Niki Radios:

Radio 1.58.16.27

- After 1 minute: 4 Satellites (2 on green, 2 on yellow)

- After 2 minutes: 6 Satellites (3 on green, 3 on Yellow)

- GPS fix at: 1m38s

Radio 1.58.21.23

- After 1 minute: 4 Satellites (2 on green, 2 on yellow)

- After 2 minutes: 4 Satellites (1 on green, 3 on yellow)

- GPS fix at: 1m55s

Radio 1.58.11.07

- After 1 minute: 7 Satellites (5 on green, 2 on yellow)

- After 2 minutes: 8 Satellites (6 on green, 2 on Yellow)

- GPS fix at: 58s

BATTERY LIFE TEST RESULTS:

(Estimated Battery life (from 0 to 100%) of this battery, working in the conditions above)

Niki Radios:

Radio 1.58.16.27 - 756 min

Radio 1.58.21.23 - 706 min

Radio 1.58.11.07 - 661 min

OPINION:

Niki Radios:

Radio 1.58.16.27 – Until now, after 2 days of usage, seems to be the best overall radio, very good reception, best battery life, good GPS fix, device seems to work faster than with many other radios (faster than with 1.64.08.21 – my last day-to-day radio);

Radio 1.58.21.23 – Also obtained very good results but, here in Portugal, but reception and battery life worse that 1.58.16.27;

Radio 1.58.11.07 – Very good reception, best Radio for GPS utilization, very fast fix, and overall performance seems to be very good too, but battery life is the worse of my tests;

NOTE: The tests made to Kaiser, Polaris and Niki Radios are avaiable in Radios thread, on post 432 ( http://xdaforums.com/showthread.php?t=349375&page=44 )
