ios 15.2 battery issues

It's been 5 days since the update in my case, and I can't really use my phone now, as it gets from 100% to 0% over 5-6 hours even when you are not using it. I don't believe any of those suggestions can help anyhow, it appears that Apple just pushed another bad update that either consumes the excessive amount of power or just there is a bug in software that doesn't check the battery status properly. I tend to believe it's the latter personally, as it happens not the first time (rather happens quite regularly, sadly). What is really frustrating is that Apple doesn't seem to test their updates properly before releasing them, and when they do release them with such issues, they don't revert them to the previous (working) OS builds.

Hey Osama_Abuzid,

We see that you're having issues with your iPhone battery and temperature, and we'd like to help!

How long has it been since you updated your device to iOS 15.2? We ask you this because after a major software update, your device might feel warm and the battery may be consumed faster than it normally would. After a software update, your device will continue to reindex all your apps and documents silently from the background. 

Please take a look at our article here for more information: If your iPhone, iPad, or iPod touch gets too hot or too cold

If you continue to experience issues with your battery life, we recommend that you apply the tips that we offer from our maximizing battery life article, and observe your battery within 48 hours to see if there are any improvements: Maximizing Battery Life and Lifespan
