Is it an official Samsung battery?
Yes. I've only ever bought new, same-model, Samsung-branded batteries.
Another fun one is un-calibrated protection ICs, which may have their coulomb counter wildly off.
Is this something fixable? I had bought a duplicate phone last year just in case but I'd rather not switch any sooner than I have to.
Edit: Might be relevant but the random shutoffs aren't like it reboots and goes on its merry way until the next one. If it gets through startup, I usually have maybe a minute before it shuts off again. That really seems like almost-dead battery behavior to me.

Assuming that this is one of those rigid battery packs with connections on one end, then sure! You just carefully open the cardboard-sticker-covering, de-solder the IC, hook it up to your favorite I2C probe, try and recognize the exact model, pull up the datasheet, issue the calibration command with your probe, direct the proper calibration current through a matched measuring resistor while the IC calibrates, then solder the IC back in and Bob's your uncle.
...or you could just buy another battery. It's easier. Sorry.

It sure sounds like it's reading the battery state wrong. But it may as well be a busted battery or moisture damage. Either way, you're getting a fraction of the rated capacity, and the IC is not recognizing this.
Now, I'm working on the assumption that you're handling one of those semi-rectangular user-changeable battery packs. If you're handling a bare cell with wires coming out, then the faulty IC is part of your phone, and you'll have to either get someone take a look at your phone's PCB, or just toss it.

Yeah, it's a plastic brick with a few exposed headers on one end. My phone is old enough to still have a user-replaceable battery so it's no big deal replacing it. I just thought it sounded like the potentially faulty ICs were part of the phone itself. We'll see what's up in a few days when I get around to installing the new battery.

A full discharge - recharge cycle (or three) may be enough to get the IC into a reasonable state. That may not be easy to do if your phone shuts off before the battery is actually discharged, though.

Yeah, one way to do that is put it into recovery mode and let it sit there: auto shutoff is not a thing in the recovery IIRC.

wat. It might cause many things, but random power-off and altered audio rate is not among them...
What you mean is "in a properly designed system, it shouldn't". Thinking all phones are properly designed is... optimistic.
Many years ago, several series of Nokia phones (including the [in]famous N-Gage everyone ridiculed) had a nasty bug. If there was not enough free space left, the boot process would fail and you only got a blank, white screen. Even the "holding keys while powering on to enable recovery mode" trick didn't work.
The only way to solve this was to rewrite the memory using special tools, which only Nokia stores (and maybe some third-party ones) had.
The bug was known for several years. But Nokia never fixed it.

I have a little side project of designing guitar overdrive pedals. Mostly just to learn (audio-frequency analog electronics, PCB design and layout, etc. Lots of interesting stuff to learn) but I intend to try to sell them once I have a final PCB design I like. It's mostly a clone of a common Ibanez design, but I made a few minor circuit tweaks to improve it for my tastes.
So my latest PCB design was a switch to SMT parts. I thought, hey, it makes the board a lot smaller and I can put stuff on two sides which was really difficult with through-hole parts, and that'll make packing the pedal much easier because it takes up less space. Sure, it might be a little tricky to hand-solder discrete SMT parts, but we'll give it a try.

Yes and no. That'll bring the battery management IC's coulomb counter to a reasonable state IIF its internal ADC was correctly calibrated upon assembly. If not, then it reads the voltage wildly off, and refuses to allow charging beyond a certain point, which I suspect is well below the cell's CV-charge voltage. I.e. you'd still only get a fraction of the pack, even though the IC thinks the pack is full.
The IC embedded in the battery pack needs to work off a very low power consumption, so the ADC in them is (typically, as far as I understand it - I've only worked with a couple of them) not designed to be accurate off the bat. The pre-amplifier coming from the current measurement even less so. The voltage amplification might be in the range of 200x-600x, and the real value is discovered in the (factory) calibration phase, when a known current is passed through the circuit, and measured by the IC for reference.
The cycling is worth a try, though. In that you're correct. It's the cheapest fix if it works. But I'd do it in a non-flammable environment. There's an IC embedded in the battery pack for a reason, and if it doesn't work... lithium-polymer batteries are very flammable.

@Zenith said in The Official Status Thread:
I immediately thought it was the battery and ordered a new one because Samsung batteries are cheap now. Last time I replaced a battery, it just ran down fast, like I could watch the percentage drop to zero inside of 20 minutes. The diagnostic mode on this thing says the battery is fine. I've been able to let it run as a phone for hours. It's always when I use the browser that it shuts off like this. But, then, I was able to run it down to 20% over the course of the day only occasionally using it. I thought it was fixed, went to take some photos for eBay auctions, and it shut off.
I've had a problem with a damaged battery, it would probably just not deliver enough volt or amp so the phone died instantly whenever it did something that required a bit more power. When started, the battery was flat most of the time, but occasionally it'd work anyway.
So you may have a damaged battery that still works, but doesn't properly follow the performance curve for discharge to the "power left" estimate is wildly off.

Which level of tiny are we talking here anyway? SOIC? MSOP? SOT?I did order some liquid soldering flux, the kind you dispense with a needle. And while I don't have a temperature-controlled soldering iron yet, I found a fairly cheap one on Amazon with good reviews I plan to buy. It might be a while, sometimes it takes 6 - 8 weeks to get PCB's from EasyEDA/Shenzen.
I have no idea what SOIC/MSOP/SOT mean. All but three of the resistors are 1/8-watt, the other three are 1/4-watt because they'll handle power and not signal. The footprints all appear to be 2 - 3 millimeters for the most part. The first part I looked at was the 1N914 clipping diodes, and they are definitely smaller than 2mm and probably the smallest part of the build (I hope...I haven't looked everything over yet.)
Here is a screenshot of the newest PCB. Hardware guys run for your life, I really don't know what I'm doing but I can get away with a lot of probably bad things because it's analog audio-frequency stuff and not high-speed digital
. The board size is about 1.45 inches by 1.1 inches. The big 3x3 array of holes allows me to solder the board straight to the TPDT switch that controls the board, for physical support and to clean up the build. Previous boards didn't solder to the switch or handle bypassing, so I had to cut and place a ton of wiring for that and it took up about a third of my assembly time, plus the older boards just floated inside the enclosure and I had to wrap it in layers of electrical tape to keep it from shorting out on the chassis.
It's a 4-layer PCB, screenshot only shows the top. Bottom layer has a few more traces and components but it isn't as busy as the top. Inside, there's a ground layer as well as a power layer that's split between 9V and 4.5V.
Once I see how this works (if it works at all, rev 3 of the board had absolutely no distortion due to a layout error I couldn't locate), I'll probably do another revision that rearranges something. If the small parts are easy to work with, I might try to pack them closer together. If not, I'll probably try to switch to larger parts. Or maybe I'll realize this is nuts and go back to through-hole.
