iOS 13.4.1 battery drain

DFU stands for Device Firmware Upgrade and it's a deep recovery/restore mode for iOS devices. You can look it up but it's basically the deepest way to wipe both the firmware and software installed on an iOS device and then iTunes will install a clean copy of both the firmware and software.

It's usually one's last hope for fixing a software problem and most iOS devices can be restored this way even if something is massively wrong with the software or firmware.

Well then I'm mystified why I was able to rectify the situation with what was clearly a less thorough reset of the phone. I'm still not letting my iPad update as I have no desire to go through it all again.

I'm not sure... Do you think you could post a screenshot of your Settings > Battery page that shows the graph of the draining of the battery? Mine basically looks like it shoots down at a 45 degree (or sharper) angle... And another member showed theirs and it was even steeper.

if you want to improve battery life there is a new software update iOS 13.5 and watch the video form Brandon Butch about settings to turn off to save battery life I will include the link for the video watch this

But it was perfect. I mean literally perfect with no complaints before 13.4.1 was installed on it. Unless the F/W damaged the battery, I don't think it's a H/W issue with the battery.

But, I could probably get a new battery for free out of it.

I’d like to stop getting email notifications for updates to this thread. I cannot for the life of me figure out how to turn off or unsubscribe to this. I know I’m missing I somewhere.

can anyone assist :)

thanks

It would be really nice if Apple would highlight the Bugs they fix. All of these suggestions were pretty bogus. I was having the same issues. Overnight I was losing sometimes 50% of the charge. I just updated to 13.5. I turned Siri back on and I only dropped about 5%. Things look much better.

If "some apps" cause the phone to heat up, you're being given a clue. Even if you need them, delete those apps at least long enough to see if their absence improves the situation. I finally got rid of the problem, but it was a very "scientific method" process.

some apps are so poorly written they do not follow the standard practices very closely

I have xcode on my MacBook and manuals galore so I know what an app needs to have to be successful

My own "bare naked except for underpants and t-shirt" reset seems to be working fine re the battery. But this isn't what I paid $1200 for.

What cables did they replace?

Please resolve this issue as soon as possible

I also have a very steep slope like you are seeing there and my battery is a bit larger being a XS Max. Had phenomenal battery life on 13.4 and prior.

Very perceptive. There's been a mix of comments here on iPhone and iPad. Both affected by the 13.4.1 update.

you might want to get your battery replaced.
