I can use the following definition for power and solve for change in energy of the battery (since the energy stored is constant in either setting): Also, both runs used the same charger.īut how much longer battery life will this give me? Let's say that in normal mode, my iPhone runs for 14 hours (a rough estimate). However, looking at the readings with nothing plugged into it I get a power of around 0.2-0.4 watts. Don't you think the total power consumption depends on the type of USB charger? Yes.Still, most of the time the phone was idle-I think the test shows (for my iPhone) that it used less power in Low Power mode. Also, at the end of the Low Power run, I received a text message. You can see during the last (and longer) run that there were some emails during that time (the spikes in the power).

But what if you get an email or text message during the test? Wouldn't that throw off the results? Absolutely-but not by that much.

But if you must know, according to the battery manager my biggest power-eating apps were Facebook, Google, and Chrome. This is all about my power savings, not yours.

That's why you might have a different power savings.

But doesn't the power savings depend on what apps you have running in the background? Yes.

Yes, I know your comments even before you do. Here is another run for both standard and Low Power mode for 30 minutes (but only in standby mode).įrom this longer data run, the Low Power mode uses about 70 percent of standard power. Really, I should have collected data for a longer period-but I'm impatient. Based on this small sample, Low Power mode uses 80 percent of the power in normal mode and 90 percent of the power in regular use. It looks like the 'Low Power' setting uses less power-so I guess that's encouraging.

Repeat the same two measurements, but in 'Low Power' mode.

Use the phone as I would in a typical 'on' situation.

I will send myself an email, to simulate normal activity.

Leave the phone in standby in the normal power setting.

The Watts Up Pro can connect to Vernier's Logger Pro software so you can record the power usage every second. Yes, there would still be some power loss in the AC to DC converter but I assumed that would be small.įor the Low Power mode on the iPhone, I will do the same thing with my own phone. My assumption was that on a fully charged battery, all of the energy would be going to run the phone and not charge it.

For that case, I charged the phone to 100 percent battery level, then plugged it into the Watts Up Pro power meter. I've looked at power consumption in smartphones before to see how screen brightness effects battery life.
