iPhone 11 How can I measure my iPhone battery use on daily basis?

[Ucshade]

Currently I have a screen on time of daily average 3hrs 39 mins but now it’s shows 4g ours 42mims on my screen on under battery section,i last charged my iPhone to 90%, my battery health still shows full capacity but right now I have 34percentbof life left when making out this post,,, pls can I say my battery life is ok…. I’ll appreciate your inputs

I’m a battery/runtime hobbyist and I personally like to compare extrapolated full batt SOT to Apple spec. Of course you can only count the SOT since unplugged, and know that cellular use is a big wildcard (depends on signal strength).

In your case it would look like 100% / (90-36%) x 4.75hrs = 8.8hrs vs 17hrs spec, or ~50% of Apple spec, which seems pretty average. Here’s an example achieving 100% SOT spec (16hrs).

FWIW, when the phone is brand new, I save screen shots of a full 100>0% rundown in 50% bands. I use this to evaluate battery capacity/health degradation over time.

You have to be aware that camera uses a lot more battery than other apps, making the battery drain more than otherwise. In your screenshot, camera is the top battery using app at 41%.

Ok?

HalfFullMoon’s point on the camera is a good one - I missed that. You’re probably in the above average SOT range otherwise.
