Hi all,

So I do a lot of walking every day but also want to preserve my battery life. I recently discovered, through the Pokemon Go app funnily enough, that my steps are not counted when low power mode is turned on.

Can I have my cake and eat it too?

If you phone will not last the day on a single charge, you likely need a new battery.

Until then remove the low power mode and top off your battery as needed.
No that’s not it, I had the battery replaced by Apple in December. I just use my phone a lot outside.

An external memory bank seems to be a better solution it seems.

I don’t believe your correct on this. I’ve used low power mode on my phone almost all the time since the 7+. I do have a count of my steps that I believe is accurate at the end of the days, for months and years of low power mode usage.

I have noticed that while on low power mode the update interval is a lot longer than while off low power mode.
For example while off the step count is updated maybe every ten minutes, with low power mode sometimes it’ll stay stagnant for a few hours before updating. Turning off low power mode usually gets it to update itself relatively quickly.

‘TLDR; If I go for a 3M run while on low power mode, it will add 3 miles worth of steps, but it takes significantly longer to credit them then when low power mode is off.

You’re giving me hope! This is good to know. I’ll try to test this out.

Yeah no problem. I truly believe it just makes the update intervals wonky. Sometimes I’ll check at 11:57 and it’ll say like 7k steps last updated a 8pm, then when I check the previous day at 12:00 it’ll have added my last 3k steps and say last updated at 11:59.
 

now i see it

I used to really be into counting steps. I had a standalone pedometer and an iPhone AND for testing purposes sometimes I counted my steps in my head for a mile.

My conclusion: the iPhone is unreliable and non repeatable for counting steps. I no longer use it (or any of the "health app" functions any more. It'll give you a number, but at least in my case after using it for several months, it's often wrong.

Would you say owning an Apple Watch makes up for it? (I’m not biased, haven’t owned an Apple Watch since it’s inception year)

If he's playing Pokemon Go a lot, an app that uses the camera, GPS, AR, lots of processing, and the pedometer to count steps, plus he's outdoors which probably means high display brightness, I can understand why even a healthy battery would be taxed.
