The battery, looks like it’s time it needs to be replaced.

arochains1231 t1_j1brrvn wrote

Most likely due to an old/degraded battery. The easiest way to check how degraded your battery health is is to go into Settings->Battery->Battery Health & Charging (here's a guide if it helps). If the percent shown any lower than 80% you should probably get the battery replaced to prevent it from happening again, or the whole phone if it's really old.

The battery wasn’t able to provide enough power to keep it on so it is limiting your performance slightly to prevent it using too much again.

It is caused by using the battery. Every phone will reach that state eventually. Just need to replace the battery.

Charles_Mendel t1_j1c5t1o wrote

The battery is degraded no longer able to support the voltage the SoC requires for peak performance. Software on the iPhone will throttle the SoC to prevent this in the future.

A lot of people saying that the battery might be dead and although this could be true it doesn’t have to be it could just be a bug in the voltage controller or anywhere between battery and output. Check your battery health before you change it.

How old is your iPhone? It looks like due to it’s age, it cannot deliver the power you are asking from it. Edit: to solve this, replace the battery or keep it connected to a continuous power supply if you’re going to be asking a lot of power.

80% is a bit early to be replacing the battery unless it’s faulty, iPhones won’t even pull performance at that battery health. This battery is probably a lot lower than that to be triggering the performance management settings

Nah. Battery health is a measure of overall capacity relative to new. The battery could be 92% capable of holding a charge, but chemically degraded in a way that it cannot output the same peak voltage or amperage.

The phone momentarily ramps up and demands full power, the battery can’t deliver, the system crashes and reboots. After reboot, performance management is applied to prevent the CPU from exceeding the battery’s current maximum output capability.

RyRyShredder t1_j1dcxn1 wrote

Replying to FknBretto (#1,020,985)

Yeah mine is at 73% and still says it is delivering peak performance. It does say I should replace it in the battery health menu, but I have never had a pop up message like this. Apple recommending replacement at 80% is just to get more money out of people.

I worked at AppleCare for a couple years, doing call evaluating. A staggering volume of calls were solved by the tech advisor simply asking the customer to read the full message on the screen/ screen sharing and reading it for them. Especially with Apple Pay calls…

“This card can not be added, please contact your bank/ card issuer.”

When Apple recommends a new battery and when performance decreases due to battery% aren’t the same at all. I’ve had devices in the 60%s before it started to impact performance.

check settings > battery > battery health. if it’s under 80%, that usually means this will sometimes happen if you get into low percentages. probably time for a battery replacement

It’s not only a bit of a cash grab; it’s very wasteful and harmful to the environment.

For reference I replaced my daily 8+’s battery 3 years ago and I’m at 76% with no degradation in performance (aside from the “new OS, who dis?” features designed for the newest hardware). Lithium batteries aren’t an annual replacement item and we shouldn’t test them like that

I didn’t say they were. I said what the official threshold was and when messages like this will generally start to appear. Under 80% is expected and generally means the battery is behaving/degrading as expected over time. Above 80% is unexpected behavior and means something is wrong.

Your battery is going out and phone might die randomly. My husband has this happen and slowly his phone started holding less and less charge. It would drain at random intervals and shut off. Once we’d turn it back on it would show like 56% battery life. Technically it still works, but sometimes it won’t turn on at all even if left on the charger for days at a time.

Your battery is failed and your phone is going to run slower now so the phone doesn’t power itself off.

What does this message say?

I'm pretty sure it says that performance was affected. Thus, you are arguing with yourself. You are saying Apple gives these messages when the phones performance is affected by decreased battery capacity at 80%, yet that battery capacity isn't affected until less than 80%.

Use Coconut Battery on a Mac to check the actual battery life, then you can decide if replacing it now or later.

Your battery is old and worn out. iOS is throttling performance to maintain stability. If they didn’t do that, your phone would be shutting down randomly. Get a new battery.

Again no. I said that generally these messages start appearing at/below 80%. The alternative, seeing this message above 80% is indicative of an unexpected hardware failure. In OP’s case, that distinction would be important in how serious to take this message.

You're wrong. These shouldn't occur at 80%. Apple recommends replacement at 80%, that doesn't mean the battery is unable to provide the necessary amperage at 80%.

You are doubling down because you don't want to be wrong, it's okay to be wrong.

Exactly what it says on the tin: battery can’t deliver enough wattage for the CPU to go full throttle, so it’s making sure the CPU lets off the gas a bit so the battery doesn’t explode.

It’s like driving at high elevation.

I mean, the message is right there lol.

Your battery has degraded enough that can’t sustain peak performance.

Your phone will be throttled down from now on so it won’t shut down at least, but eventually you’ll have to replace your battery to get back your performance and your stamina.

Again, the message tells you what caused it.

Specifically, putting a damaged battery under a heavy load will cause the output voltage of the battery to drop below the threshold voltage required to make a diode actually pass current. Effectively, this is the same as taking the battery out of the circuit momentarily and the device starts up from a power failure when the voltage returns to the breakdown threshold.

Get a new battery

ihooper05 t1_j1evp4r wrote

Your battery is fucked. Check your battery health, if it’s under 80% then it needs to be replaced for optimal performance. Also this could be caused in combination of the battery health being low and cold temperature. I had a 13 Pro Max with 97% health do this because I used it in the Canadian cold.

I've had a 12 mini for 2 years and I'm at 88 battery health. I thought the 13 mini is supposed to have a larger battery? Must all be down to usage I guess.

I absolutely love the mini iPhones. Wish they had not discontinued them. I plan holding onto mine for as long as possible. Will likely get a battery change from Apple once the health dips below 60.

Your battery is aging, and likely needs to be replaced. When batteries get old, they are unable to deliver as much power when the phone is running intensive apps or doing something strenuous. Now your phone is slowing itself down so it won’t need to deliver as much power. You’ll notice your phone is slower now, and I’d recommend replacing the battery.

Yep that makes sense. Personally, if I had this problem and couldn’t replace the battery, I’d put it on low power mode from the second I unplug it until it dies. And don’t leave it in a cold car. This should help until you get a battery replacement or until you get a new phone. With my old iPhone 7 that I mentioned before, I used this method and it worked great

You realize batteries can fail in ways other than capacity, yeah?

The amount the battery holds (capacity) Is not the same as current.

One is how much it can hold, one is how much power it can supply per second until the capacity is depleted.

Anything from heat, cold, or chemical failure in the battery can cause this kind of issue, you can have over 100% batt health and the battery can still be a lemon if it drops cells or electrolytes cause expansion.
