I have over 15 games on my device. Some do occupy some memory; others not so much. I have enough leftover memory on the phone.
Is it true that this can slow down the device?
When you download and install a game on your device, the data is stored within internal storage. When you run the game, it loads all the assets into RAM, which is Random Access Memory. Accessing RAM is much faster than accessing internal memory, which allows games to load scenes, animations, and other things faster. The game should know exactly where the assets are in RAM with an memory address. It can jump right to that point and pull the information down.
However, games are not the only thing that uses RAM. The operating system, system applications, and other installed apps are also using RAM. The more RAM that is used, the less there is for new operations to occupy temporarily. If RAM gets too full, then it could cause problems.
Leaving applications running in the background leaves RAM occupied. After a while, the memory should automatically be cleaned up, especially if you start new applications that require that space in RAM.
Another culprit that could be slowing things down is cache. Cache is used to store app information, web site data, and other information that the app will use to speed up load times. If too much cache is used, then it could be slowed. Games can use a lot of cache since they need to load images faster. Clearing the cache occasionally is typically a good thing.
Yes, running many games can cause a slow down on your device. RAM that does not get cleared and having too much cache are the main culprits. RAM should resolve itself over time, though closing the app completely is a good idea just to make sure. Clearing cache every so often is a good idea as well, especially if you run many of the games often.
Downloading too many Apps (not only games) might slow down your device. It depends strongly on the apps you are dealing with.
The mechanisms for slowing down Android performance are various. It may be due to background processes, low available memory, and perhaps communication issues.
The question is quite broad, and I will try to avoid repeating information, so I will point to appropriate sources.
You could check which apps are eating up your resources. For instance, Trepn profiler is recommended here. I have used it some time ago and I recall finding it quite useful, in particular for a slowed-down device.
Note that when identifying resource hog apps, it is likely not a good idea to use an app killer on them.
This old question and its answers might be useful: My device is getting slow, apps start misbehaving/crashing. What can I do?
Yes. Believe it or not, the less free space you have in ROM, it can eventually affect the load speed for apps and their the files associated with them because it takes longer for the phone to find and access the info it needs, especially if you have less than 32 GB total storage. Not so much if you have a large memory (like an iPhone or Samsung Galaxy, both of which come w/ up to 128 GB, depending on the model). It still will get slower the more memory is used, but the memory access time for a phone with that much storage is such that even if it takes 2-3 times as long, it would still be so fast you couldn't notice the difference.
Yes it does..at one point of view....it basically EATS your RAM and this causes slowing down of other apps and your whole phone......it also causes superheating problems.....it also depends on your mobile set.I.e.its hardware and all.anyway.....the final answer is YES
In my case That is not correct because when you install certain games are applications at that time some of they contain i mean they required low cpu and GPU power and some of them they don't even required that
