iPad throttling?

Isn’t the damage already done? The feature is already in iOS, future upgrades shouldn’t change that.
You have 6GB free space out of 128GB.
Might be worth doing an iTunes encrypted backup/restore to free up cached storage and maybe force a SSD secure erase or TRIM.
I believe 1.3GHz is the normal frequency for the mini 2.Here is my iPad mini 2 slowed down a little bit at 57% battery. Current Frequency is 1300MHz vs. 1400MHz.

The iPad mini with Retina Display rounds out the three platforms that use Apple’s A7 SoC. Although both the iPad Air and iPhone 5S use the A7, the mini’s implementation is closer in nature to the iPhone. The iPad mini’s SoC has always used the same package-on-package (PoP) assembly as the iPhone, with DRAM stacked on top of the SoC itself (1GB in this case). The benefit is obviously a reduction in board area, the downsides have to do with cost and thermals. That’s the first similarity between the mini’s A7 and the iPhone’s A7.
The second is one of frequencies. While the iPad Air’s A7 runs its two Cyclone CPU cores at up to 1.4GHz, the SoC in the iPad mini and the iPhone 5S runs at up to 1.3GHz. That might sound like a minor difference, but it’s far more pronounced when you look at what happens to frequency when you’re running heavy workloads.
Once again I turn to a fairly heavy CPU workload to plot performance over time. This is a multithreaded workload, slightly modified from what we used in the iPad Air review, designed to make the CPU cores consume max power. The scale is linear and the workload is the same across all devices, so what you’re effectively looking at is a graph of thermally bound CPU performance over time across all three A7 implementations:
Being the largest device (and the only device with a metal heat spreader and no DRAM stacked on top), the iPad Air obviously maintains the highest frequencies for the duration of the test. The iPhone 5S, with a significant reduction in internal volume (and a PoP SoC) reduces its CPU frequencies early on in order to keep skin temperature down and properly manage thermals. The iPad mini with Retina Display falls between the two, with its performance curve more closely following that of the iPhone 5S.
Although the mini has a similar max operating frequency to the iPhone 5S, it is a faster device thanks to it being less thermally constrained. Similarly, the iPad Air can be much faster than its clock speed would otherwise imply. If you’re wondering why Apple has been so focused on building its own SoCs and CPU architectures, this is the reason why. There’s a fixed amount of power you can dissipate in the form of heat in these mobile devices while still maintaining a good user experience. Performance per watt is the gating metric for success in mobile, and shipping high IPC/low frequency dual-core SoCs at 32/28nm is the best optimization available to a company like Apple today.
As you’d expect, our browser based CPU tests show the mini’s A7 performing in between the iPhone 5S and iPad Air. None of these tests are anywhere near as stressful as our thermal test from above, so we don’t see exaggerated differences in performance between the platforms. For most, I suspect you won’t notice a huge performance difference between the mini and Air. Those who are heavier users (e.g. audio mixing, 3D gaming, etc…), there will be a performance difference between the two iPads.
I just want to update that throttling appears right now only to affect iPhones, not iPads or other Apple devices. I have an iPad mini 2 that is a couple of years old with latest iOS installed and it still has not lost any CPU Frequency now that the battery charge level is at 24%. Still showing at 1300MHz CPU Frequency.

I believe only specific iPhone models are affected, too. Haven't experienced throttling on my 5s (11.2.1) yet.
Do a clean install using iTunes and restore as new then add all your apps and it will run nicely.. Don’t use a backup...
I've not had performance issues with my Mini 4. Sporadically, I get issues with the keyboard, where it seems to mis read what I'm typing. I was going to take it into the Apple store once, then it started working well again.
Yesterday, for the first time, the iPad just turned off at 13%. Powered it on, and it thought the battery was dead. Plugged in, was at 13%. When this happened 1 1/2 years ago with my iPhone 6, I replaced the battery.

Really bad advice. Sometimes there are reasons not to update but as a general advice - it's not ok to avoid updates by default. iOS updates contain security patches, bug fixes, etc.
And no, it does not apply to iPads or MacBooks or anything with a battery large enough that it can sustain the power draw even after being worn out.

The op was referring to 3 minis and the newest mini is almost 2.5 years old.
Blindly upgrade whenever Apple asks is also a bad strategy. Depends on when the device came out; if it's within a year or two it has a good chance to be all right. With older devices, throttling or not, they get stressed by newer, more demanding iOS.
I do not disagree, I just think “do not update iOS” (especially if the reason is that you’re affraid of throttling) is bad as a general advice. Sometimes, there are some valid reasons not to update, if the new iOS will make your device really slow due to new background processes or features, etc.
I get it now. Yeah, I do agree.
Though personally I like to be cautious since it is usually impossible to roll back. The caveat is sometimes I might miss a good version.
One thing you can do is update before the next major firmware update is released (e.g. iOS 7.1.2 just right before iOS 8 release). That way, most of the bugs have been fixed and there's already plenty of feedback on how well it runs on older hardware. Almost always, newer firmware versions run slower than older ones, anyway.
I want to report something suspicious. My iPad mini 2 battery charge was at around 4% and I noticed it was much more laggy or slower than usual when browsing, as opposed to at higher battery charge. For example, when I was browsing this website, it would take more than 10 seconds for the page to display but we have a very fast internet connection. I only noticed it now because of the whole iPhone slow down talk. But the CPU Frequency did not change from default. So, definitely something mysterious going on.
Yeah, they are. It can be changed though with the right tools. I’ve never done it, but there’s people that have and said it wasn’t terrible to do.
I had the same question, but since my geekbench, with the same model, is better than yours, I shouldn’t worry. I also ran a third party battery app that gives percentage of capacity, and sometimes is says 79% and other times 81%. My AppleCare expires in about 4 months, so I hope it bad enough by then for Apple to replace the battery. Has anyone had there’s replaced when it was right near the threshold? And is it done in the store while you wait? Thx!
