Hello Apple team and community,
I’m reporting a critical issue affecting iPhone 13 (128 GB) on iOS 26 Public Beta 3.
Problem Summary:
• Device stays stuck at 1% battery, even while charging
• Battery Health shows 0% in Settings
• Phone reboots every 5 minutes while unplugged
• Only works when connected to power
• Cannot update, charge properly, or maintain uptime
Additional Context:
• The issue appeared immediately after installing iOS 26 beta 3
• Affected devices often have a replaced battery (even official or high-quality replacements)
• Seems to be a software validation bug related to battery firmware
• Reported by many users across Reddit, Apple Forums, and Twitter — but not listed in Known Issues
What Has Been Tried:
• Recovery Mode / Safe charging / Clean install (same version) – no effect
• Third-party repair tools (ReiBoot, 3uTools) — partial workaround
• Jailbreak with Nugget or iCleaner to disable crash daemons – temporarily helps
• Apple Support suggested full device replacement (!)
⸻
Request:
Please investigate and acknowledge this issue. This bug renders devices unusable for users with legitimate battery replacements — we need a fix in an upcoming beta.

We are develop an application with corebluetooth framework. we connect to device with ble. and open two l2cap channels. it can transfer data with stream. but when it close the second l2cap channel, it always close the first l2cap channel.
Is it mandatory to use classic Bluetooth (Bluetooth Classic) to connect game controllers that support Apple’s MFi games and Arcade games, or can game controllers be developed using only Bluetooth Low Energy (BLE) for such accessories?

After research, we found out that a crash occurs in QuickLook when a user tries to open a file with unknown mimeType - application/octet-stream.
QuickLook convert that files to known type (for an example - application/pdf), but crashes for the first opening the file.
Any help would be greatly appreciated!

I’m encountering an unexpected issue while using NEHotspotConfigurationManager.shared.apply(...) to connect to a Wi-Fi network. Specifically, I’m receiving a userDenied error, even though the user did not interact with any system prompt.
Here’s a version of the code I’m using:
let config = NEHotspotConfiguration(ssid: ssid, passphrase: passphrase, isWEP: false)
// config.joinOnce = true
NEHotspotConfigurationManager.shared.apply(config) { error in
if let err = error {
let nsErr = err as NSError
mlog("err.code:\(nsErr.code)")
if nsErr.code == NEHotspotConfigurationError.alreadyAssociated.rawValue {
self.findWiFiListAndConnect(ssid, passphrase, overtimeSec, timeStart)
} else {
self.cmdDelegateQueue.async {
self.delegate?.wifiClose(nsErr.code)
}
}
}
}
The error returned is:
wifiClose status: 7
Which corresponds to NEHotspotConfigurationError.userDenied. According to the official Apple documentation, this error should only occur when the user explicitly cancels the system dialog. However, in my case:
• No system dialog appears.
• The user does nothing, yet the error is still returned.
• This issue does not happen every time, but it has been observed across multiple devices.
Additional info:
• iOS version: 18.5
• Device model: iPhone
• joinOnce is not set (defaults to false)
• Existing configuration is removed using removeConfiguration(...) before applying
Is it possible that under certain system states (e.g. backgrounded, network restrictions, or app permissions), iOS silently fails without showing the prompt?
Has anyone else encountered this issue, or does anyone know what could cause this behavior?
Any help is greatly appreciated!
I am debugging ImageCaptureCore to communicate with external cameras.
When I called the PTP function below to send a command and add data, the response timed out for more than 5 seconds. After waiting for a period of time, I obtained the response. However, the response callback function obtained responsivData.length as zero and ptpResponseData.length as zero too.
(void)requestSendPTPCommand:(NSData *)ptpCommand
outData:(NSData *)ptpData
completion:(void (^)(NSData *responseData, NSData *ptpResponseData, NSError *error))completion;

Hi, as other threads have already discussed, I'd like to record audio from a keyboard extension.
The keyboard has been granted both full access and microphone access. Nonetheless whenever I attempt to start a recording from my keyboard, it fails to start with the following error:
Recording failed to start: Error Domain=com.apple.coreaudio.avfaudio Code=561145187 "(null)" UserInfo={failed call=err = PerformCommand(*ioNode, kAUStartIO, NULL, 0)}
This is the code I am using:
import Foundation
import AVFoundation
protocol AudioRecordingServiceDelegate: AnyObject {
func audioRecordingDidStart()
func audioRecordingDidStop(withAudioData: Data?)
func audioRecordingPermissionDenied()
}
class AudioRecordingService {
weak var delegate: AudioRecordingServiceDelegate?
private var audioEngine: AVAudioEngine?
private var audioSession: AVAudioSession?
private var isRecording = false
private var audioData = Data()
private let targetFormat = AVAudioFormat(commonFormat: .pcmFormatInt16,
sampleRate: 16000,
channels: 1,
interleaved: false)!
private func setupAudioSession() throws {
let session = AVAudioSession.sharedInstance()
try session.setCategory(.playAndRecord, mode: .spokenAudio,
options: [.mixWithOthers, .allowBluetooth, .defaultToSpeaker])
try session.setPreferredIOBufferDuration(0.005)
try session.setActive(true, options: .notifyOthersOnDeactivation)
audioSession = session
}

case .denied:
delegate?.audioRecordingPermissionDenied()
completion(false)

}
}
func toggleRecording() {

} else {

}
}
}
}
private func startRecording() {
guard !isRecording else { return }
do {
try setupAudioSession()
audioEngine = AVAudioEngine()
guard let engine = audioEngine else { return }
let inputNode = engine.inputNode
let inputFormat = inputNode.inputFormat(forBus: 0)
audioData.removeAll()
guard let converter = AVAudioConverter(from: inputFormat, to: targetFormat) else {
print("Failed to create audio converter")
return
}
inputNode.installTap(onBus: 0, bufferSize: 1024, format: inputFormat) { [weak self] buffer, _ in
guard let self = self else { return }
let frameCount = AVAudioFrameCount(Double(buffer.frameLength) * 16000.0 / buffer.format.sampleRate)
guard let outputBuffer = AVAudioPCMBuffer(pcmFormat: self.targetFormat,
frameCapacity: frameCount) else { return }
outputBuffer.frameLength = frameCount
var error: NSError?
converter.convert(to: outputBuffer, error: &error) { _, outStatus in
outStatus.pointee = .haveData
return buffer
}
if error == nil, let channelData = outputBuffer.int16ChannelData {

let data = Data(bytes: channelData.pointee, count: dataLength)
self.audioData.append(data)
}
}
engine.prepare()
try engine.start()
isRecording = true
delegate?.audioRecordingDidStart()
} catch {
print("Recording failed to start: \(error)")
stopRecording()
}
}
private func stopRecording() {
audioEngine?.inputNode.removeTap(onBus: 0)
audioEngine?.stop()
isRecording = false
let finalData = audioData
audioData.removeAll()
delegate?.audioRecordingDidStop(withAudioData: finalData)
try? audioSession?.setActive(false, options: .notifyOthersOnDeactivation)
}
deinit {
if isRecording {
stopRecording()
}
}
}
Granting the deprecated "Inter-App Audio" capability did not solve the problem either.
Is recording audio from a keyboard extension even possible in general? If so, how do I fix it?

As of iOS 18.1 being released we are having issues with our users experiencing issues with our app that relies on strobing the device torch.
We have narrowed this down to being caused on devices with adaptive true-tone flash and have submitted a radar: FB15787160.
The issue seems to be caused by ambient light levels. If run in a dark room, the torch strobes exactly as effectively as in previous iOS versions, if run in a light room, or outdoors, or near a window, the strobe will run for ~1s and then the torch will get stuck on for half a second or so (less frequently it gets stuck off) and then it will strobe again for ~1s and this behaviour repeats indefinitely.
If we go to a darker environment, and background and then foreground the app (this is required) the issue is resolved, until moving to an area with higher ambient light levels again. We have done a lot of debugging, and also discovered that turning off "Auto-Brightness" from Settings -> Accessibility -> Display & Text Size resolves the issue.
We have also viewed logs from Console.app at the time of the issue occurring and it seems to be that there are quite sporadic ambient light level readings at the time at which the issue occurs. The light readings transition from ~100 Lux to ~8000 Lux at the point that the issue starts occurring (seemingly caused by the rear sensor being affected by the torch). With "Auto-Brightness" turned off, it seems these readings stay at lower levels.
This is rendering the primary use case of our app essentially useless, would be great to get to the bottom of it! We can't even really detect it in-app as I believe using SensorKit is restricted to research applications and requires a review process with Apple before accessing?
Edit: It's worth noting this is also affecting other apps with strobe functionality in the exact same way
Hello
I've noticed that this product, heavily promoted on the ASC forums for many years, is no longer available from the Apple App Store.
Can anyone tell me the reason why the product is no longer supported?
Friends have asked me if it is 'safe' to use.
Is it?
Note to moderator: If I'm asking in the wrong places, please redirect my question. Thank you.
Prerequisite: After the MDM APP issues the command, the camera on the phone is no longer visible (unusable).
After upgrading to iOS 26.1, the isSourceTypeAvailable: UIImagePickerControlSourceTypeCamera method keeps returning true when the camera is unavailable.
The isSourceTypeAvailable: UIImagePickerControlSourceTypeCamera method on iOS 26.0.1 is normal, returning false when the camera is unavailable and true when it is available.
On iOS 18.x when try to create EASession we get nil, but on iOS 17.x everything works.
We have app which use USB cable for connecting external accessories.
Scenario is when we have fresh instal, connecting with accessory work fine, EASession is created, streams are opened.
When we unplug USB, we close streams, remove any reference to session and accessory, remove accessory delegate.
When plug it again, creating EASession is returning nil. Only after restarting iPhone, we can create new EASession with appropriate protocol and accessory. Every next attempt without reseting iPhone is failing.
Logs from accessory is following:
00:05:51.811000 : onUSBDeviceFound(pDevice=0xffc818)) iPhone USB device already in the device list w/id=1 -> update status now[21;1H
00:05:51.830000 : setConnectionStatus(status=connected) [devId=1] state updated -> forward[21;1H

00:05:52.848000 : updateDIPODeviceConnections() iPhoneUSB w/caps=5 (=CarPlay or HostMode), deviceTag=2 in Device mode -> request role switch[21;1H
Role switch seems to be successful

Native transport should become available but does not (the following line is not present for failed case. Taken from successful case)
00:05:24.983000 : OnDBusPropChanged_NativeTransport(): deviceId=2, started=1, iAP2iOSAppIdentifier=1, sinkEndpoint=3, sourceEndpoint=4, TransactionID=1
EAP Start event not received (trace line from success try)
00:05:25.057000 : EAPSessionStart(ctx=0x74e0b800){2} called[21;1H
Is there any braking change on iOS 18 considering EASession?
Also what is strange is that it works on fresh instal/restart iPhone, but not working on second attempt?
I have a command line utility I wrote that has been working great up until Sequoia that reads the macro keys from a Logitech G600 gaming mouse and turns it in to custom commands. it was using the following code, checking if usage was 0x80:
IOHIDManagerRegisterInputValueCallback(
g600HIDManager,
{ _, returnResult, callbackSender, valueRef in
let elem = IOHIDValueGetElement(valueRef)
let usage = IOHIDElementGetUsage(elem)
let pressed = IOHIDValueGetIntegerValue(valueRef)
Now i'm having issues with opening the HID manager:
IOHIDManagerOpen(g600HIDManager, IOOptionBits.zero)
After changing the system security from permissive to restrictive, It's giving the error code 0xE00002E2, or no permission. I can't easily add the sandbox entitlements as this is just a simple CLI application, not a bundled app, and even after setting back to csrutil disable, i'm still getting this error.
So now i'm trying to turn it in to a bundled app and use CoreHID instead. Unfortunately I'm not getting any notifications that aren't the mouse itself. From the above code that was working before, i was looking for usage values of 0x80. I'm guessing that directly corresponds to the usage 0x80 in the HID descriptor. I am receiving notifications via
await deviceClient!.monitorNotifications(reportIDsToMonitor: [] , elementsToMonitor: [] )
which should pick up everything for the device. I know the usage i'm looking for is referenced in the device client because it's in the deviceClient.elements collection.
So is there something in CoreHID that specifically blocks Vendor specified Usage pages from being picked up by notifications?
I've also tried just requesting the elements using
let elemToMon = await deviceClient?.elements.filter({ ele in
return ele.usage.page == 0xFF80 && ele.usage.usage == 0x80
})
let request = HIDDeviceClient.RequestElementUpdate(elements: elemToMon!)
let results = await deviceClient!.updateElements([request])
but that call errors (still trying to figure out exactly how it errors).
Any help would be appreciated, either in figuring out why i'm not getting the HID reports in question using CoreHID, or even what has changed that is causing me to not be able to use IOKit.hid anymore.
Thanks in advance!

Dove in and upgraded two Macs today to beta 1. Unfortunately, it appears L2TP VPN is broken or something changed in the way it works. I can longer get a connection to any VPN concentrator I used previously. I tested with Cisco Anyconnect SSL VPN client and can connect to the same concentrators (as they're configured to accept L2TP or SSL clients).
I also tested from my phone running iOS 16 beta and it still works for the L2TP connections.
The Mac not working with L2TP VPN ppp.log shows this
Fri Jun 10 19:18:52 2022 : L2TP connecting to server 'IP removed' (IP removed)...
Fri Jun 10 19:18:52 2022 : IPSec connection started
Fri Jun 10 19:18:52 2022 : IPSec phase 1 client started
Fri Jun 10 19:19:02 2022 : IPSec connection failed
Connecting a Mac successfully on 12.4 the log shows
Fri Jun 10 19:12:33 2022 : L2TP connecting to server 'IP removed' (IP removed)...
Fri Jun 10 19:12:33 2022 : IPSec connection started

Fri Jun 10 19:12:34 2022 : IPSec phase 2 established
Fri Jun 10 19:12:34 2022 : IPSec connection established
(and then a ton more lines of the entire process ending with client getting an IP that I won't bother posting)
VPN wasn't high on my list of apps I was concerned about breaking with the beta. But, now that it is broke and I need it for work I'm kinda screwed myself.
Anyway, if anyone knows a way to fix this please let me know.
