Objective Battery Test for all iOS based devices

[aakshey]

Hi.

There’s an app on the App Store called Battery HD+.

It simulates real world safari usage.

Let us all do this test:

Short Interval Test Wifi Internet 30-60 minutes

Keep the brightness at 75%. Don’t turn off 4G.

Let us see the results we get.

On my X, my battery drains about 5-6% in the 30 minutes test. Regardless of iOS 12.2, 12.3 or 12.4 beta 1.

iPad Pro 10.5 on iOS 12.2 fares the same.

If I turn off Wifi and just use 4G, the results are more or less the same yet again. Both for iPhone X and iPad Pro 10.5.

Unfortunately in real world usage my battery drains twice as much because this is a very very light test involving only Google and not much movement.

iOS 12.2 5%

Ran multiple times.

Why? What would this accomplish. I don't need an app to tell me what my battery life is. What are you trying to accomplish?

There is never a good way to simulate real world usage and certainly not a good way to compare due to variables like radios reception, temperature, background refresh, notifications and calls you are or aren't getting during the process, touch screen usage, auto brightness, True Tone, other iOS devices in the vicinity of the test (airplay, handoff, continuity, airdrop), battery degradation, gauge calibration is a HUGE factor, etc etc.

You are just putting unnecessary usage cycles on the battery.

Apple also removed a lot of the battery data obtainable from the IOKit framework in iOS once they released their battery information. MacOS can still access it but not directly though iOS, battery cycles for example. Although there used to be a work around using UIDevice, not sure if Apple stopped that yet or not. Point being those apps aren't very useful anymore.

That said, you can use your devices to compare iOS versions since you have limit outside factors. Sample size is small but its only really applying to you anyway.
