No.

Lack of traffic can simply mean no one has asked for help, so no one
else has reason to post a response. Best way to determine if a
newsgroup is dead is to ask for help, and wait a week for responses.

So that's good confirmation that any further issues won't be down to the battery.

Despite unsubstantiated (likely fabricated) claims by nospam
what I'd like to know from others is how you think this compares to what

I could find no mention how 3utools measures battery health. In fact,
there is little info on anything in the tools suite. Measuring by
voltage is not a valid indicator of a battery's health. Since coulombs
cannot be measure for the battery's capacity, about the only other
method is to record and graph the discharge and charge rates over many discharge/charge cycles. However, that is only an indicator of battery
health, and still does not measure capacity (coulombs).

A battery that charges to 100% may still only provide a small portion of
a good battery that has far more capacity. A 100% battery could drain
in a couple hours because it has less capacity versus a 100% good
battery that takes days to drain until the same loads.

Other than some vague "health" measure, does 3utools actually define how
they measure health? Without a history measuring charge and discharge
info, such "health" measures are worthless. Just measuring charge rate (amperes times seconds) would indicate coulombs, and keeping a history
would be needed to determine if capacity is waning, and by how much
(because all batteries wane in capacity over time). The voltage across
the battery does NOT measure capacity.

Some mobile devices let apps query the charging rate, some don't. If
not, amperes cannot be measured which means capacity cannot be measured.
Since often charging is perform when the battery has been drained to
different levels, a history is needed to graph charging rate at
different start points.

Does 3utools provide any information on how they measure capacity, or is "health" some nebulous measure that might be based solely on voltage?

you're looking in the wrong place.

the *battery* reports its health, which can be read by software and
reported to the user, much like smart monitoring on hard drives.

Measuring by
voltage is not a valid indicator of a battery's health.

which is why that's not used for the battery health report.

Since coulombs
cannot be measure for the battery's capacity, about the only other

no, that's not the only other method.

3uTools is sketchy. Their web site is no secure. Not sure what country
it's based in, but you see a large number of spelling and grammar errors.

I suspect that 3uTools looks at the maximum battery charge percentage
and your battery cycle count and tries to guesstimate the battery health.

There is also iMazing <https://imazing.com/> which you can install on
your computer. They don't say how they determine battery health on the iPad.

I don't know what's wrong with Steve as we already discussed it's from
China. And yes, it has the sloppiest spelling, showing lack of attention to detail.

I suspect that 3uTools looks at the maximum battery charge percentage
and your battery cycle count and tries to guesstimate the battery health.

Again, I don't know what's wrong with Steve that he's so ignorant even
_after_ I provided the detailed screenshots of what 3uTools reports.

There is also iMazing <https://imazing.com/> which you can install on
your computer. They don't say how they determine battery health on the iPad.

Again, and again, I provided _exactly_ what iMazing reports for my own
iPads, so it's strange Steve is still completely unaware of those facts.
