    iPhone 13 mini not doing icloud backup, how to transfer data to new phone?

    I have a launch date iPhone 13 mini, so almost 5-6 years, I love this device, but I'm a pretty heavy user, so the small battery suffered kinda hard along all those years, so much so that it's sitting at 56% health, and because of that I believe, it's failing kinda catastrophically, like, calls...

    iPhone Air iPhone Air replaced iPhone Air (Battery & iOS Systemdata)

    Hi I bought the iPhone Air on launch day, In September 2025. 2 weeks ago I sold it, regret it, and bought a brand new iPhone Air again 😅 But what I'm experiencing on my new iPhone Air is surprising to me. The new iPhone Air has been running for 8 days now, and I did set it up as a brand new...

    My Trusty S7 Is Dying

    Due to heart issues I can't be without my Apple Watch. It has literally saved my life when I passed out cold on my bedroom floor and I monitor my heart rate all day every day. The battery is at 85% and I updated to 26 as soon as it was available but over the last 3 days the watch has started to...

    "Find My" drained my battery overnight

    Since Nov. when I bought this, I charge the phone at night and always leave my 17 Pro Max off the charger overnight and wake up to 100% daily. Always been great, no problems. Not sure what this is - As usual, I left it off the charger last night, woke up earlier than usual this morning and see...

    Battery cycle count lagging? (1 cycle logged at 120% discharge)

    Hey everyone, I’m seeing some weird logic on my iPhone Air. After some initial troubleshooting and resets, my cycle count was at 3. I started monitoring the cumulative energy consumption in the analytics to see when it would flip. Mathematically, it should have hit cycle #4 at 100% discharge...

    Right APP3 suddenly loses charge

    Too often, my right APP3 suddenly loses its charge. I have thought perhaps that the pod somehow keeps a BT connection even once securely back in a closed case. My iPad is nearby, but BT is turned off. Apple TV box is not far away. What other things might be in play?

    Does downgrading macOS improve battery life?

    My MacBook Air M2 which I got new back in August 2022 has a maximum capacity of 91% left, and running macOS Tahoe on it causes it to drain from 100% to like 91-90% in one 1 hour when I browse the web, and overall the battery does not seem to last as long as before. I want to know, does...

    Charging Ultra 3

    At Christmas I treated myself to an Ultra 3 and I'm loving it so far! With my previous Series 7, I had to charge it every evening as the battery would be down to around 15% by the time I went to bed. In contrast, the Ultra 3 is still showing around 80% at the same time of night. Awesome...

    Charging a Macbook from a Mac Studio: does it harm the battery?

    Hi, people. Technical question about batteries. I rarely carry the charger when I need to work for a few hours with my M5 Macbook. When I get home, I usually keep the Macbook lid-closed by my side on the desk, charging from a USB-C cable attached to my Mac Studio while I work. It charges...

    I currently own a iPhone 15 Pro that is two years old and it has 820 charge cycles and 88% maximum capacity, I got to say in terms of battery life, the 15 Pro was not great and my drain rate with continuous usage on like ChatGPT is 1% for every 3-4 minutes or 10-12% per hour. This is not new...

    Best Way to Use MacBook in Clamshell Mode Without Killing the Battery

    Hi everyone, how’s it going? I have a MacBook Air M2 and I want to use it closed (clamshell mode) connected to an external monitor, keyboard, and mouse. My goal is to work on battery power only — the place where I’ll be using it has very few outlets, so keeping the Mac plugged in all the time...

    Notification saying my apple USB-C charging cable is an accessory, and the battery graph says it's slow charging?

    So I have used the same USB-C cable with a wall socket adapter, both from apple, for about 4 years. A few days ago, when I connected the cable, it said it was an accessory and to unlock to use, which as I understand it is the usual behaviour for accessory's. But the cable shouldn't be recognised...

    iPhone 14/Plus Battery dilemma and questions

    I have a 3 year old iPhone 14, which I’m happy with, but the battery seems to suffer, even though it’s at 85% capacity. I have done dozens of battery changes for other people, but never on my own devices, because I don’t want to loose and functionality etc. But changing the battery at apple...

    Other Comprehensive breakdown of fast charging and charge limit myths

    Amazing video. I think it has real potential to put an end to the usual battery debates about whether fast charging is harmful or if setting a charge limit actually makes a difference.

    iPhone 17 How is the 17's battery life so solid?

    I know battery life is difficult - so many things affecting it on a person to person basis. But I've probably watched 12-15 different battery comparisons now, and I don't fully understand how in so many of those tests (not all) the 17 is actually very close to the 17 Pro, who's battery (e-sim)...

    iPhone 17 Pro Battery Health and Longevity better with larger size?

    This might be a dumb or obvious question. I've had a Pro, returned it for the 17. I think the 17 is excellent for the value. But the only thing that has me a little hesitant on sticking with it for a few years (vs. the Pro) is the battery size. The 17 Pro's battery is massive given the...

    New anti consumer design? - Battery Usage

    So. Stone me for calling it what I did. But only if you can tell me 1. why we needed a completely new design for the battery usage pane in Settings and 2. how it is actually meaningfully better than before. I admit the previous pane wasn’t too helpful either, especially when it was buggy and...
