Help Does too much cache, widget on desktop, too many apps drain battery faster?

[Adrian Recamadas]

I've read alot of threads about this but I prefer having a personal answers from you guys. I play drastic emulator (ds emulator, a chinese version, sort of a hacked one). And everytime I use it, it leaves 512mb of cache and junk files. I am still observing the difference if I clear the cache and when I don't. So far as I have observed, battery drained every hour even when not used, and also it drains faster when i don't clear 512mb cache, 2% for 5mins, and 1% for 5mins when i clear cache (estimate). About my widget, I only use sticky note and google calendar widget for my meetings and schedules. And if you're asking why I play ds. I just like playing pokemon. Regarding the apps I have 28 apps dowloaded.And my phone has no modification, I did not fladh new rom, not rooted (I dont want to root), I'm using KitKat 4.4. I HOPE YOU CAN ANSWER MY QUESTION GUYS! Peace out.

There's nothing in the nature of a cache file in and of itself that can eat battery.

That's like - your shoes wearing themselves out just sitting in the closet.

However - if an app is sneaky enough or sloppy enough it can cause battery issues.

Android sort of learns your behavior over time and queues up your most-used apps so that they're ready to go faster when you're ready to use them.

It does that by grabbing cached apps, not just the app.

The cached state ought to be as quiet as the shoes in your closet.

Some games break the rules and simply try to take over the phone because, you know, you bought your phone just for them.

You can't judge that in minutes, you have to measure it in hours or days to be sure.

System Panel is your best friend for that, it's in the Play Store - and anything in the cached or inactive list is using *zero* battery.

If you prove that clearing cache for that app matters, that's not caching and it's not Android - it's a bad app.

The fact that you mentioned that you clean up junk files from a game is very interesting.

Temporary files are files. Do your pictures eat battery when you're not looking at them?

No. No they don't. Because they're just files.

If you've picked up the term junk files by using a battery helper or a cleaning app - and "cleaning cache and junk files" is what they love to advertise - then you want to stop that. Uninstall them yesterday.

Automated cleaners are what eat your battery and they flat out lie about what they're really doing. It's all covered in detail in the thread I linked.

Cache files are not programs. They're just data files. They do not start running processes so cannot use power. But by deleting them, you do waste power because - as you have seen - they will just rebuild themselves. Leave the cache alone.

Widgets use power, some very little, some a surprisingly high amount. The 2 you're using would be low power use. Don't worry about it.

It doesn't matter how many apps you have installed. You could have hundreds of apps installed doing nothing, with zero effect on the battery. What matters is how many apps are trying to start and run. Apps fighting over RAM and CPU cycles, starting, getting kicked out in favor of other apps trying to run, restarting, kicked out, restarting - this kinda stuff is what kills the battery.

To get much more information about is happening with your device, System Panel is an excellent tool:
