Apple MagSafe Battery Pack review: convenience over capacity | The Verge
The new Apple MagSafe Battery Pack is designed specifically for iPhones. It is elegant compared to Anker’s battery, but it doesn’t provide as much charge as many will need.

MagSafe Battery Pack | Discontinued, Capacity, Specs
When anything MagSafe is used with leather cases, expect a slight indentation from the MagSafe magnets. This is expected and described in the product support information by Apple. The MagSafe Battery Pack has a 1,460mAh capacity at 7.62V.

It's official, the Apple Vision Pro (600g~) + Battery pack (353g) is almost 1kg. Without the separated battery, it would be one of the heaviest headsets out there.

Without wheels my car would not be very good

Wesley Hilliard: Apple's MagSafe Battery Pack has more capacity than it seems - here's why. The MagSafe Battery Pack appears to have a tiny capacity when examining its milliamp-hour rating, but that isn't the whole story. Here are the battery ratings and what they mean to users.
TLDR All phone manufacturers use Ah as unit of energy because all Li-Ion batteries have 3.7 V on average (which is still misleading anyway). While the true unit for energy would be Wh (V*Ah). In this case, where the voltage of the battery pack (7.6 V) is much higher then the usual 3.7 V, speaking of Ah is pretty useless. More on reddit.com

Apple Magsafe Battery Pack - A few days in
I find it better to slap it on my phone when my phone is at 100%. So when I know its going to be a long day ill put it on as soon as I take it off the charger. I did this and the magsafe battery died by 6PM and my phone was still at 85%. The magsafe battery kept my phone around 90% until it was dead. If I remember correctly, this is how the iPhone battery cases worked too, its pretty much the same thing just not in case form. Its a battery extension not a full on external battery charger and it seems most people are confused by this. It can work like that if you put your phone in low power mode, and doing this charges it past 90%. These are just the finding I have seen. I like it better than my external anker one tbh. I hate dealing with cables and micro usb and the MagSafe regulates itself rather than just pushing power to my phone so it lasts longer than a battery charger would. I also like that when both it and my phone are dead, I can plug in one of the two and it charges both devices at the same time. That is pretty handy too. just my opinion on it. More on reddit.com

iOS 14.2 has massive battery drain issues, especially on older iPhones.

If you’re like me and running iOS 14.2 on an older iPhone like the OG iPhone SE or 6S/7/8 then you might have noticed that the battery life is not what it used to be.

For me, battery life on 14.0 was horrible while on iOS 14.1 it looked a bit better. Now I’m on 14.2 and battery drain is bad again.

While it seems to be fine on standby, kinda trivial tasks like fetching eMails, texting a short message or opening Twitter seems to sap several percents of the battery in only a minute.

Today I found this forum post in the Apple dev forums, confirming that it might not just be me, it’s true for many folks, especially on old phones.

I don’t want to speculate what features of iOS 14 might contribute to this or even Apple „deliberately“ nerfing old batteries (my capacity is still at 93%) to persuade you to buy newer ones.

I only wanted to make a point that if you’re experiencing this, you are definitely not alone and that I hope that Apple fixes this very soon, as it makes using a phone in such a state impossible without a charger nearby.

That’s all.

Edit 1: Removed all widgets, as suggested by u/Starchedpie and battery drain seems as awful as before: Rebooted and unplugged from charger at 100% at around 1 PM (CET). Now it’s 6 PM and after sporadic use (occasionally check Reddit and eMails) I‘m on 54%...

Will try disabling Covid contact tracing tomorrow and see how that goes. If that fails, I might try a factory reset and restore from backup.

Apple MagSafe Battery Pack
Since all the iPhone 12 models have 3.81V batteries and the MagSafe Battery Pack has a 7.6V potential, the Battery Pack’s effective mAh capacity is actually 2,920mAh. (A lot of math is involved in figuring this out; Apple Insider’s Wesley Hillard does an excellent job of breaking it down.) The snappy way to recharge your iPhone 12

Which 2025 iPhone Has the Best Battery? I've Crowned a New Power Winner - CNET
1 month ago - If you're using an eSIM-only version of either phone, like the iPhone models sold in the US, your battery is even bigger because it takes up the space where the SIM card tray would be. Frustratingly, Apple doesn't share the capacity of the iPhone's batteries, and part of the reason is that its batteries are often smaller than those in Android phones.
