Appkiller android forums5/5/2023 ![]() If you do need one, it generally means you have a poorly designed app and you should blame the dev for that. The Android task manager is very well designed and you shouldn't ever need a task killer app. Even if the system was designed to set all bits to zero, that wouldn't actually make them use less power in real terms. This is somewhat of an simplification but when RAM is emptied it is not really physically emptied, the OS just notes that those bits can be overwritten whenever they are needed for something else. No, memory is always on and doesn't use more power jsut because there is something "live" in it. It certainly can do, if Android is constantly reloading apps that you are killing. is the air-speed velocity of an unladen swallow? Does Killing and restarting apps decrease battery life due to increased CPU Usage ?Ģ Does memory itself use Battery life if the items in memory are not using CPU ?ģ Does having low available ram matter when the CPU actually does the work and can Android kill fast enough when Ram is required to meet an applications requirements?Ĥ What. I would like anyone to comment on the following:-ġ. My quadrant benchmark with Appkiller was 538, without it is 567. Generally the Apps in memory are using ZERO cpu usage !! Looking at the Tasks tab shows how many apps are running and the memory used, but crucially also shows the CPU usage of thoe apps. It shows info on when the system considers ram low and starts killing apps as well as loads of other system info and logs. Using Android System Info I can see that available memory is at times about the same as after performing a kill, suggesting that Android handles resources well left to itself by auto killing apps or processes when ram is low. Since unistalling the Task Killer the phone is much faster in general, by my perception. I uninstalled Advanced Task Killer and installed Android System Info. However my phone has been lagging recently and after reading a bit more people were suggesting Task Killers were the cause of this. Seems to me like very few (none on my phone) apps actually do anything when in the background (they have 0% cpu), so the battery usage won't really be saved.After reading on here that task killers were a MUST have I was running advanced task killer. There's also several apps around that show you how much CPU the apps are using (I use 'top'). ![]() ![]() Most apps that support fetching data like this allow you to switch it off anyway. You're only likely to save battery power if the apps in the background are actually doing anything (downloading/uploading data, or just CPU work in general). It's also worth killing off apps that use high CPU for no reason (most likely they are buggy and should be uninstalled anyway!).Īnother reason to kill of the apps is to save battery power. If RAM usage gets very low (I'm talking like <5mb at a guess), then it's probably worth killing off the apps. However there's quite a bit of debate as to whether killing apps off is a good thing.Īs a developer myself, the fact the Andriod is using up RAM is a good thing. There quite a few apps around that let you kill off selected apps at the touch of a button (Advanced Task Killer is the main one people use). ![]()
