Here's my little experiment:

• Fairphone 4, brand new, totally stock Fairphone OS, a few resource-light apps installed, light use for a week: 23 hours of use time from 100% to 20% battery on average.

• Wiped the same Fairphone 4 after a week, installed CalyxOS (deGoogled Android), reinstalled the exact same apps and used the phone the exact same way for a week (I still do in fact...): 44 hours of uptime on average.

I know with 100% certainty that literally the only difference between week #1 and week #2 was that the phone didn't spend its time constantly reading the sensors and sending surveillance data to the mothership.

So there ya go: even if you're mad and you're a fan of Google's dystopia, the extra load on the system does come with a significant performance pricetag.

Check the Google settings. If one of them is constantly recording your position, that'll drain battery rather quickly.

Telemetry. Welcome to Android.

I've been raving mad about this exact shit for years.

I'm not a developer, but I remember how long pre-smartphone would last with little 500mAh batteries. Even after 3g and into 4g connectivity and well after the proliferation of less efficient Bluetooth a phone would last anywhere from 3-14 days between charging.

Now every phone has 3,000-4,000mAh batteries and, besides 5g, the wireless standards have become significantly more efficient.

The only notable offset is the big touch screens, but even those have gotten more efficient, and seems not to matter because standby time is still trash now too.

I doubt there's a continous A/V feed to servers, but 100% our phones are always listening for keywords/phrases locally and then sending "relevant" data back for ads, on top of the always on location tracking.

It's hilarious that phones cost as much as they do, considering how unwieldy and low screen-time they've become, on top of the idea that we're paying to be tracked.

Are they 2 different phones? Different phones behave differently

I'd guess different setups both of the phones and accounts. For example if one has enabled Google location in settings, and stuff like location sharing isn't disabled, the phone will be pinged much more often. Same if you have office documents on cloud, synchronisation with phone book and stuff like that.

And yea it makes sense that an account that's more active is of more interest to ping more regularly. Maybe also for security too. Tho I don't know if it has to be an actual conscious decision by the designers of the systems or just some AI algorithms doing it.

Are those 2 phones the same model?
