I own the S21 Ultra. Without having to go into each app individually to clear the cache, is there a procedure to clear the phone cache all in one go in order to speed up the phone.
1.Turn off your device. 2. Press and hold the Volume Up + Power keys together for about 5 seconds. 3. You will see the list of options >> choose wipe cache partition. It will clear all cache of the system and all apps. You can exit the Recovery Mode on Samsung devices by selecting the Reboot system now option.
Hmmm...In recovery mode, Wipe Cache Partition is remove temporary system data in system cache partition. This suppose to make the system access apps more faster and quicker. However, it is different from clearing individual app caches. I guess you have to clear individual app cache one by one manually.
This is the only way to clear all cache without doing it app by app. I personally tried it many times no harm. if you are ok with using a 3d party software it can wipe the cache for apps and browsers only you can use CCleaner software.
I understand is no harm. However, the app cache is under each app folder/cache folder. But Wipe Cache Partition is clearing system cache, not app cache. 2 different things.
I know there are many 3rd party apps that can clear apps cache all at once.
Clearing the cache won't speed up your phone. In fact, it'll probably do the opposite since the entire point of the cache is to avoid the app, or the system, to constantly load stuff again when the app is opened (like images, text, pages, etc.). Cache is there to help speed things up, not to slow it down especially if there's loading anything from the web like Instagram, Facebook, etc. Try scrolling down Instagram or Facebook then delete the cache for the app and you'll notice how no images are downloaded and you'll have to re-download all the data it loaded before. This would also impact your battery and data usage since it'll re-download files and will also make your phone work harder to create the cache files again.
I seriously don't know why clearing the cache is always recommended here. It should only be cleared if you're experiencing any issues with the app like things not loading/working correctly. If that doesn't work, deleting app data next, then reinstalling the app is the last resort for troubleshooting. It's rarely ever needed and won't do anything.
The one reason I'd clear the cache is if it was taking up a lot of data (like hundreds of MB or GB that's clearly not needed like, let's say, a reddit app). Apps should delete the older cache files after a while so it's most likely not needed.
Same with going to Recovery and deleting Dalvik Cache or deleting the Cache Partition. 99% of the time, it won't even do anything and is just placebo to make it seem like it speeds up your phone. There's a reason why that menu is hard to get to and isn't user facing since it isn't needed. Fun fact: when a software update is installed on your phone, it should have done the step of deleting both the dalvik cache and cache partition when it goes to the blue Android screen and why it says Optimizing Apps when your phone loads. The only time it's needed to even delete it is if your phone is acting really wonky like something being out if place or if there's a lot of force closing of system apps.
The only reason why it's even recommended now is because of flashing custom firmware which was pretty prevalent years back where it was needed because of how different custom roms were where it was needed to avoid any problems when switching between them. It was always recommended that you do that that people outside of XDA caught wind of it and just recommend it as a catch all to fix problems despite it not even being needed at all -- or if ever.
So yeah, stop and let Android do its thing.
