MagSafe Battery Pack Now Able to Charge at Faster 7.5W Speed After Firmware Update

The magsafe battery with the latest firmware actually charges at 7.5W :)
Attached image with 1500mAh charging rate.
It is also possible to see that it controls the temperature quite well, when the battery reaches 36ºC, it suspends charging and starts charging again moments after it drops to 34ºC.
However, I still have no option to limit loading to 90% :( :(

Have you tried detaching the pack, doing a full shutdown (including disabling after-shutdown localization), powering on again and reattaching?

I've done all these steps:
1- Charge the Magsafe Battery up to 100% with apple charger 20w
2- Connector to magsafe battery on iphone, the option does not appear.
3- Fully discharge the magsafe battery to 0% and charge it again
4- charge the magsafe battery connected to the iphone
5- charge iPhone with lightning with the magsafe battery connected.
6- Turn off and turn on the iphone several times.
7- It was tested on 3 iphone 13 pro max, and an iphone 12 pro, all with the same symptom...

Yeah that’s all just speculation, and internet myths. There’s not data showing MagSafe charging shortens battery life.

You can chalk this up with the “leaving your phone charging overnight is bad” myth.

These myths have been debunked by Apple and reputable tech testers.

I don’t know anything about magsafe charging shortening battery life. My post was about power transfer efficiency of inductive charging vs. contact charging.
 
Do Americans know the word naff? It's the perfect word for these things. One of the naffest products Apple sell.

Was finally able to get over to my dad’s place and use his MacBook to update in a matter of minutes after days of fruitless waiting with my phone (seriously, Apple?) and the option to “charge past 90%” under the low power mode shortcut is still there. I’m sorry you are having such trouble with yours—sounds like maybe a faulty unit given everything you’ve tried :confused:

How do you check the firmware to know it’s updated? Mine arrives tomorrow as thought I could use it for those long days away

Just tested this. My MagSafe battery was completely useless before, unable to charge my device at all. In fact, even on airplane mode with low brightness it would still discharge on downloaded videos.

Now? Charges when idle, holds charge when using. It is premature, but this update might have made this battery useful for me! Out of the drawer it comes.

How much extra heat does it generate with 7.5W ?

To be honest I havent a good enough sense of temperature differences or a good enough memory of how much it used to generate to answer this.

I havent used it in a while because its largely been useless for me in the past.
 
Is there a way to NOT have it charge at 7.5W? My phone and battery pack are now noticeably hotter than they were previously. I don’t see any options, so I’m guessing the answer is “No”. I thought I would ask anyway just in case I was missing something.

I knew charging at 7.5W would cause more heat, but I didn’t expect this much more.

(Note: Even hotter, it could still be a perfectly-safe level of heat that isn’t hurting either battery. I’m not a battery expert, so it possible that this is not an issue at all. But both are definitely noticeably hotter than they were before the update.)

wireless charging always generates more heat than with a usb cable.
However, most of the heat is caused by the induction coils that generate heat with the transfer of energy.
The heat that stays on the back of the iphone is not the same as the heat that reaches the battery, as I have been monitoring the temperature of the battery and after the temperature reaches 35ºC, charging is interrupted momentarily until the temperature drops and it resumes automatically again.
However I would like to know if your magsafe battery still has the option to limit the charge to 90%, with the new update??

Was under the impression it still won’t charge over 90%

Here is how you manually update the firmware:

All you need to do is to connect the MagSafe Battery Pack to your Mac via USB-C to Lightning cable and leave it connected for a few minutes. Make sure you are on the latest macOS, it will automatically update the firmware. (Also works with iPhone and iPad, but you won't be able to easily check for progress as on Mac.)

If you are interested, you can open the console and filter "updater", you will see a few processes in the background checking and updating the firmware for your MagSafe Battery Pack.

You can also check look for the firmware update file located at "/System/Library/AssetsV2/com_apple_MobileAsset_UARP_A2384/"

And if you dont have a mac to plug it into?
 
I thought this new ability to charge at 7.5 W would be a godsend, but I’m still having instances where the battery is draining faster than the battery pack can charge (or maintain the charge of) the phone.

Same... I'm very disappointed

What I haven't seen anywhere is how long does the Magsafe take to fully charge the iPhone (I'm about to buy a 13 Pro, haven't had an iPhone since the 5). And how long does the official Apple travel battery pack take (even though I believe it only offers a 60% charge?) Thanks!
