S23 Ultra Battery Drain

[DissPair101]

I've had my phone for three months. About 2 weeks ago, the battery life became horrible. I went from getting 7-9 hours of Screen On Time and 12-14 hours of standby to barely getting 5-6 hours of screen time. What the hell is going on?! I didn't change any apps or install anything and my usage is absolutely the exact same!  Why is this happening? I paid thousands for this phone. Why is it being so crappy?

Different things can affect the battery @DissPair101 such as temperature where you reside , and network signal.

If network signal has degraded then the phone would need to work harder to maintain connection. 

Using two sim cards in the phone can use more. 

Having 5G turned on in Settings and Connections then mobile network can hse more juice.  So if you don't use 5G then if your phone allows you change to Lte /  4G / 3G / 2G

Please ensure your phone and apps are fully up to date. 

Then go into Settings > Battery and Device Care > Battery > And look at Battery usage to see if one or more of your apps has gone rogue. 

In the same section tap on optimisation. 

Other steps you can take are >

• Clear Cache Files from the phone's System Partition Section  > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop or use a Tv's USB Port to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too. 
• Safe Mode  > https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/ turns off downloaded apps and themes etc which may highlight an app or theme that's causing conflict.
• As a last resort back up and factory reset.

I appreciate your response. 

I am currently in Saudi Arabia. The temperature is around 30-35 Celsius but I'm usually in an air conditioned room. 

I only use one SIM. 

I don't use 5G since I'm always on WiFi, which I turn off when I'm sleeping. My brightness is on auto and I have adaptive battery on since day 1. None of the apps are rogue either going by the usage stats I have seen and everything is up to date. 

When I got the phone, I was using Bluetooth Buds 2 Pro way more and it was still using less battery than it is now and I'm barely using my buds in the last ten days because of the poor battery! 

As for the partition clearing and all, I will try it but honestly I think it's stupid to pay thousands for a flagship and then have to do such heavy maintenance on it and dig into little things like that. Samsung really screwed people with this.

I just wanna know why this started randomly three months into using the phone and the change happened overnight. What the heck even happened is what I'd like to know from them

You're very welcome @DissPair101 

I assume you have no app crash logs etc either. 

Do send any feedback via your Samsung Members App too. 

I'm on the latest software update and have a Samsung watch and use my Buds Live everyday to commute all connected vja Bluetooth and my battery usage has remained stable. 

Unfortunately it's not always an easy process to troubleshoot these types of issues so can be a step by step process or invariably the issue Rights itself.

I wish you all the best.

There's nothing else that's gone wrong except the battery and it's really bothering me. Like right now I'm sitting here using my phone and I've had less than 6 hours of screen time and just over 9:30 standby time and my phone is at 33%.

Thanks for all your help though. I appreciate it all. Samsung needs to help
