Battery issue on replaced phone
I recently bought a new iPhone SE and transferred all of my data. I want to keep the old iPhone and have removed most of the Apps. However when I charge it fully at night, the battery is almost dead the following morning. This was not the case before I bought the new phone. When I check the battery app, it doesn't indicate any use that would explain why the battery is almost exhausted.

iPhone battery health
I have an iphone 15 pro, it’s only 4 months old and the battery health has dropped by 2%(98% now). I don’t let my battery drop below 25% and change only to 80%. I use an original apple charger and cable. The total battery cycle count is only 117. I don’t understand why it’s dropping so quickly. Can anyone help ? Thanks

Apple Watch Ultra 2 battery life since watchOS 11
Since installing WatchOS 11 on my ultra 2, the battery life has decreased significantly. This morning alone (in the space of 4 hours) It has dropped 23%. This isn’t normal for my watch to drop that much in such a short period of time. I’m wondering if there is a setting somewhere that has turned itself on with the update and causing the watch to use the sensors more, shot in the dark. I have also noticed the watch is recording more exercise minutes (when not in a workout) than it did previously before the OS 11 update.

iOS 17.6.1 vs app issue
We've been using our app for the past year, and a user came back today that after three minutes, their phone starts getting hot and the screen dims. He is using 17.6.1 with an iPhone 14 max. No one else is seeing an issue, but with the posts online about 17.6.1 battery drain, I wonder if our AR app is somehow more sensitive to the issue.

Iphone 15 battery dropping fast
So , i have bought my Iphone 15 in the release week . Since the beginning i’ve noticed some overheating but i brushed it off since so many people were having it , but i still feel like it overheats especially when using the camera and making calls. 10 months later , my battery health is at 88% at 308 cycles , which would be 1 charge per day . Im worried its dropping too fast tbh and i wanted to know if this is normal .

Does Battery Usage metrics include active VPN tunnel statistics?
Hi, we have an iOS VPN app that uses NEPacketTunnelProvider. One of the Metrics that we track in XCode Organizer is Battery Usage (On-Screen Battery Usage, Background Battery Usage). Could you clarify: Does Battery Usage statistics in XCode combine app's and active tunnel's battery usage or just the app's battery usage? When the app is not active and not in background, but VPN tunnel is active, does this reflect in Battery Usage statistics per app versions?

Battery Health Drain 1% every 10 days
My AppleCare is about to expire (a week) and I am experiencing 1% battery health decrease every 10 days or so. I use my iPhone 14 pro max lightly, and usually full charge it every 2 days. Followed all the tips that Apple recommends to maintain battery health, all of them did not work. Went to Apple store to get it fixed, but I have to pay out out pocket because it is now 94% and not eligible for AppleCare coverage that is supposed to be 79% or less. Suggestions would be appreciated on what should I do to get the battery replaced with my coverage. thank you

Really High Energy Use
I'm developing an app where users can select items to add to a screen, similar to creating a Canva presentation or choosing blocks in Minecraft. However, I'm encountering an issue with energy usage. When users click the arrows to browse different items, the energy use spikes significantly. Although it returns to normal after a while, continuous clicking causes the energy use to skyrocket. The images I'm using are 500x500 pixels. Ideally, I would like to avoid caching all the images, as the app might have up to 500 items and caching them all would consume too much memory. I have tried numerous way to avoid this but I just can’t seem to make it work. Would anyone know how to avoid such problem? I have included a picture of the energy use when just opened, and one after like 10 seconds of continuously clicking on an arrow to see more items. Also a picture of how the app looks. struct ContentView: View { struct babyBackground { var littleImage = "" } @State var firstSet: [babyBackground] = [ babyBackground(littleImage: "circle"), babyBackground(littleImage: "square"), babyBackground(littleImage: "triangle"), babyBackground(littleImage: "anotherShape"), babyBackground(littleImage: "circle"), babyBackground(littleImage: "square"), babyBackground(littleImage: "triangle"), babyBackground(littleImage: "anotherShape") ] @State var secondSet: [babyBackground] = [ babyBackground(littleImage: "circle"), babyBackground(littleImage: "square"), babyBackground(littleImage: "triangle"), babyBackground(littleImage: "anotherShape"), babyBackground(littleImage: "circle"), babyBackground(littleImage: "square"), babyBackground(littleImage: "triangle"), babyBackground(littleImage: "anotherShape"), babyBackground(littleImage: "circle") ] @State var thirdSet: [babyBackground] = [ babyBackground(littleImage: "circle"), babyBackground(littleImage: "square"), babyBackground(littleImage: "triangle"), ] let columns: [GridItem] = Array(repeating: .init(.flexible()), count: 4) func createBackgroundGridView(for backgrounds: [babyBackground], columns: [GridItem] ) -> some View { LazyVGrid(columns: columns, spacing: 10) { ForEach(0..<backgrounds.count, id: \.self) { index in Button(action: { }, label: { if let path = Bundle.main.path(forResource: backgrounds[index].littleImage, ofType: "png"), let uiImage = UIImage(contentsOfFile: path) { Image(uiImage: uiImage) .resizable() .frame(width: 126, height: 96) } }) } } .padding() } @State var indexOn = 0 var body: some View { HStack{ Button(action: { indexOn = (indexOn == 0) ? 2 : indexOn - 1 }) { Label("", systemImage: "arrowtriangle.left.fill") .font(.system(size: 50)) } Spacer() ScrollView { switch indexOn { case 0: createBackgroundGridView(for: firstSet, columns: columns) case 1: createBackgroundGridView(for: secondSet, columns: columns) case 2: createBackgroundGridView(for: thirdSet, columns: columns) case 3: createBackgroundGridView(for: thirdSet, columns: columns) default: createBackgroundGridView(for: firstSet, columns: columns) } } .frame(maxWidth: .infinity, maxHeight: .infinity) Spacer() Button(action: { indexOn = (indexOn == 2) ? 0 : indexOn + 1 }) { Label("", systemImage: "arrowtriangle.right.fill") .font(.system(size: 50)) } } } } Energy Use when app starts: Energy use after clicking for about 10 seconds: App UI:
