I previously had a serious battery drain and overheating issue with my Samsung Galaxy S24 Ultra after a recent software update.
After trying several things, I eventually discovered that WhatsApp Backup was causing the problem. Once I turned off WhatsApp backups completely, the overheating stopped and my battery life returned to normal.
However, I still need to back up my WhatsApp data.
Whenever I try to run a manual backup, it gets stuck at around 57% for hours. During that time, the phone becomes very hot and the battery drains quickly, so I eventually have to stop the backup to avoid keeping the phone at a high temperature for too long.
Has anyone else experienced the same issue, especially on the S24 Ultra?
If yes, did you find any solution that allowed the backup to complete successfully without the phone overheating?
I’ve already tried contacting WhatsApp Support, but unfortunately it hasn’t been helpful. So far, I’m only getting automated/AI responses with generic troubleshooting steps.
Any suggestions or experiences would be appreciated.

Have you made sure the app is up to date? Are you sure you have sufficient storage space in Google? I don't know why, since WhatsApp is a Meta app, that it backs up to Google, but it does not like there's a way to change it. There is an option to add another account for backup, but I'm sure that it means another Google account. I am having no issues. As a matter of fact, I did not even realize that WhatsApp backs up at all until you posted this.

Hello ammarata, and thank you for getting back to us in order to further troubleshoot this matter. Now that we have narrowed down to the main issue being when you use WhatsApp, may I ask if you are attempting a backup using Wi-Fi or is it over cellular data? Let us try switching one from the other to see if this will help. We want to make sure we have as strong a connection to the network as possible this time, this way we can observe if it has something to do with the network or possibly the size of a file. Please don't hesitate to get back to us, we hope this will help!

i used both, Wi-Fi and cellular data, in different times, and different Wi-Fi networks with excellent speed.
my backup size is about 30 GB, i removed the videos, but can't remove the photos.
@AAbbott thank you for taking time to response, and looking for solution with me, however, i can't take the risk to reset my phone, with no WhatsApp back, i have lots of data and conversations.

Well, you can do a Smart Switch complete backup to a flash drive or Samsung's temporary cloud storage while you do the reset. This will preserve your personal data and captures more than the nightly automatic backup. (The automatic backup never captures your personal data.), but it may include the WhatsApp data, albeit unencrypted.
You say you can't take the risk of a factory reset, or even uninstalling and reinstalling WhatsApp, but let me ask you what happens to your WhatsApp data if your phone is lost, stolen or just plain stops working? It would all be gone anyway. If you use WhatsApp on multiple devices, all your chats are just there, so I don't believe you would lose anything. The Google backup is just insurance. If you have another phone (even an older one) or a computer, install WhatsApp on that device and link it to your account, you'll see your chats are there (likely because of the Google account link). I have it installed and linked on two computers, my watch and my phone, and my chat history is identical. You might find help here: https://faq.whatsapp.com/?locale=en_US
