My iphone has been overheating lately, 🤔

Read one good tip, forget where, just try to avoid using your phone while charging it if it is starting to overheat. But also, if it is really heating up, to stop charging it just in case. Makes sense. Going to try that next time.

But what is the temp anyway?

Nice, learned from here, https://www.guidingtech.com/how-to-check-iphone-temperature/, you can access your iphone temp through the Privacy Settings, Analytics data. Looks like I had this turned on so I downloaded two of my last files there,

Analytics-2024-08-23-200007.ips.ca.synced
Analytics-2024-08-24-200007.ips.ca.synced

and changed them to .jsonl since they look like json lines files.

read that and also noticed , nice polars has a sql read interface?

Because appeared that the temp key last_value_AverageTemperature is nested.

import json
import polars as pl
from pathlib import Path

data0823 = Path("Analytics-2024-08-23-200007.ips.ca.synced.jsonl").read_text()
from pathlib import Path
data0823 = Path("Analytics-2024-08-23-200007.ips.ca.synced.jsonl").read_text()


df23 = pl.from_dicts(
[json.loads(x) for x in data0823.splitlines()]
)
df24 = pl.from_dicts(
[json.loads(x) for x in data0824.splitlines()]
)
df23.shape, df24.shape

# Out[12]: ((1216, 37), (1151, 37))

cool looking schema

Ok here looks like my phone’s average temp past two days has been 26 C

More granular temp would be nice though

also noticed other temp keys

Can look at them another time, but noticed casually, some of them have pretty wild values actually.

last_value_BatteryTemperature
first_value_BatteryTemperature
last_value_MaximumTemperature
last_value_MinimumTemperature

I saw the line "last_value_MinimumTemperature":-21 ! And "last_value_MaximumTemperature":459, putting all of the values validity into question hmm.
