ipad battery drain rapidly increased in the last week.

[Chris]

My gen 9 ipad with latest iOS has suddenly draining the battery rapidly.

I've had it over a year and up until now the battery has lasted several
days despite me using it every day. Now it lasts about half a day.

My usage hasn't changed at all. I almost exclusively use Notes for
handwritten notes of meetings. This is reflected in the battery history
80-90% Notes.

There's no battery health view on the ipad so can't tell whether this is
a battery problem. Is there any way to find out whether it's a hardware
or software requirements?

[News]

No delta on an i9 iPadOS 16.3.1 (loaded within the past week).

Why not ask the iPad forum?

[Chris]

If the iPad is jailbroken there's a Tweak to enable Battery Health, see

Then how is battery health enabled on iPad?

i didn't say it could be enabled on the ipad.

i simply said there's no need to jailbreak to get that info, and there
isn't.

there are apps that run on both mac os and windows that can query it
(and other info).

[Chris]

I'd like to know as well.

[Chris]

Blaming the magnetic cover seems like a bit of a reach.

[VanguardLH]

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.

[*Hemidactylus*]

So in your world fictitious people are still buying and using desktops or
laptops? Apple shits on people who don’t. Why can’t iPad users get the same
info that iPhone users do?

[insert bullshit convoluted nonsplanation here]

[*Hemidactylus*]

So iPads are not self-sufficient. I was just told by nospam: “there are

apps that run on both mac os and windows that can query it (and other

info).”

Lame!

[Chris]

Seems like a couple of extra reboots fixed it. Working as normal today.
Phew! I really depend on that ipad.

[Wade Garrett]

Once I removed the cover, the problem vanished. After several days, I
put the iPad back in the cover and the problem returned.

Repeated for another cycle. Same results.

Seems like a reach to you-- but it ain't ;-)

[Jolly Roger]

Nice. Probably just a software malfunction (app or system service).

I recall reading about this issue. If the smart cover moves slightly
then the screen comes on and the battery drains faster. If the iPad is
sitting on a table it's not going to matter but if it's in a briefcase,
pack, etc., even slight motion can wake it up.

My question to this lying piece of shit is why I can’t get an answer on
battery “maximum capacity” on my ipad but can on my iphone.

You actually played into his lying fucking bullshit. Jolly Roger should
come by and gaslight everyone as to why that is unimportant. Seriously
don’t fucking bullshit me more assclown liars about how this is unimportant
because you are fucking lamers. Pay almost a thousand dollars for a high
end iPad and have fucking liars lie. Lying assclowns.

Implicitly admitted is that ipads are not self-sufficient. You need a
Windows PC to check battery health. Low end bullshit.

[*Hemidactylus*]

Oh wait for nospam to respond did I need to add question marks??? What an
evasive lying piece of shit.

[*Hemidactylus*]

Fuck nospam.

[*Hemidactylus*]

I spent almost a grand and Tim “Piece of Shit” Cook doesn’t think I need
feedback on my battery health? Fuck him too scumbag piece of shit corporate
asshole, nospam, and Jolly Roger too. Fuck the customer as we are always
wrong.

[Jolly Roger]

You should probably seek the help of a psychiatric professional to learn
how to cope with your trauma.

Long ago I observed what Hemidactylus did about the iKooks who will stab
their own mothers in the back if that defends Apple's honor at all cost.

*Why do the Apple Apologists constantly send poor unsuspecting iOS users on wild goose chases?*
<https://groups.google.com/g/misc.phone.mobile.iphone/c/ynh0PE9lK_I/m/XPxZMUkaDwAJ>

The iKooks have no honor. No shame. Nor morals. No knowledge. No heart.

I've got round to connecting my ipad to my Windows with 3uTools and found
the battery have 99% health.

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

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.

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

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.

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.

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.
