Radio test with graph
 

Using the Battlog program, I ran benchmark tests on the Sprint 1.11.00F, USC 1.07.06F and Telus 1.04.05V. I do not yet have a complete set of data but I think I can conclude a few things. Signal strength varied between 95 and 97% and did not seem to correlate to a particular radio. I show only watt-hours because that takes into account battery voltage, assuming it was calculated correctly. Current draw can be misleading without knowing voltage but if someone would rather see the average current draw (or mAH) I will make a graph with those values instead.

One bug I noted in Battlog is that if you don't save the log right when it finishes, the phone data becomes invalid, as it continues to compute the values and includes them in the saved log. That is what happened to the second Telus test and why I didn't include the phone portion.

Are my values in the ballpark, particularly among people with "Excellent" battery life?

Not sure why I can't edit. I meant to add the following:

I also read somewhere that the current usage goes up as the battery drains and the thought at the time was some kind of defect. It's not. It's just the way electricity works. For a given power level, you multiply voltage by current. If the voltage drops (like because of a draining battery) the current must increase to sustain the required power output.

Interesting but I am not sure I understand your graph.

Re: Radio test with graph
 

What do you not understand? How the data was collected or the way it is displayed in the graph?

Re: Radio test with graph
 

Maybe move this to the CDMA upgrades section.

wow, dont take this the wrong way but someone was boredd =p hehe

Re: Radio test with graph
 

Did you repeat the tests and average the results? If so, then your results do seem significant. However, if you did not then it seems likely that the significance was lost in the system noise.

Your views on voltage and current are absolutely correct. The phone compensates for voltage drops by drawing more current in accordance with P = I x V. While transmitting, the transmitter chooses a power level, P, to transmit at and the dynamic regulator chooses an I and V to satisfy it.

That said, the system is not as simple as that. dynamic (or switching) regulators are rarely that simple as they introduce their own efficiency on top of their energy conversion. And it just so happens that dynamic regulators tend to become less efficient as input voltage drops. What this means is, as battery voltage drops the power drawn from the battery increases, not just the current.

Psystem = Pbattery x %efficiency

So, if the system is consuming 1 watt and the efficiency is 90% then the battery is supplying 1.11 watt. So, if the battery voltage is 3.8V then the current supplied would be 292mA.

However, if the battery drains and voltage drops to 3.7V and the efficiency drops to 80% then the battery is supplying 1.25 watt, or 338mA, just to supply the system with that same 1 watt.

Each test is displayed singularly. However, I could average the 3 1.07.06 results as well as the Telus results. You can kinda see what it would be just by looking at it, though. I need to do more tests with 1.11.00F but I also want to flash the stock 1.03 back and test that 3 times.

New graph with averages.

Re: Radio test with graph
 

label your axes!

BAD STUDENT!

Re: Radio test with graph
 

lol ur bringing back awful memories man!

Re: Radio test with graph
 

It is labeled you moron, look in the legend.

Re: Radio test with graph
 

The legend contains the unit, WH or watt-hours. Your electricity is metered in kWh, and is a measure of total power consumed in a given block of time. Amps (current) are an instantaneous measurement and average current doesn't tell you anything about power or the total energy used. But one thing to watch out for is the WH number reported by Battlog when charging. The battery will reach voltages upwards of 4 and I noticed the WH number becomes artificially inflated.

Also, so far this Telus 1.04 radio is working out nicely. I seem to have more bars in places, and it is the closest to my old phone of all the radios I have tried.

Re: Radio test with graph
 

lol so which one should i flash and which is better thats what i care about bottom line

Re: Radio test with graph
 

Can any conclusion about whcih radio is best be reached from this data?

Re: Radio test with graph
 

Not really, given that different areas make some radios more effective due to length between closest carrier tower to cell phone. Not one of those test will match when tested in California vs New York or even Canada.

There has got to be a way to find the distance of the towers we each respectively connect to and then post the results of each Radio..

Re: Radio test with graph
 

harsh..especialy coming from a person with only one post...

Re: Radio test with graph
 

I guess this went over everyone's head. This is a BATTERY TEST, not a reception, performance, or any other kind of test. What, is everyone suddenly perfectly happy with their battery life??

Re: Radio test with graph
 

I think its good info. And yes the display on the "Y axix" showing kW/hour clearly shows battery consumption info.

I still think the reason we all have different preference in radios, while running similar setups/ROMS is because of tower locations and positioning.

The weaker the signal, the more the battery works to find better reception. Pretty basic stuff.

From the looks of your tests, they all seem very close in performance.

When in fact alot of us in different areas that have tested these radios vigorously have huge discrepancies.

Re: Radio test with graph
 

Dropped a couple calls on the Telus 1.04.05. First time that happened in all my radio testing, though I've only had the phone for 2 weeks. I honestly think battery life is close among them, reflecting my testing.
