Clearing Cache Files Of Apps In Nexus 7Support

    Hello there. Just gotten my Nexus 7c about 3 weeks ago. Overall it was a very good device with an affordable price I get the latest android version and alot of good stuffs. 3 weeks of usage I've noticed that the cache files for my apps are eating some space in my storage. So my questions are :

    - Do we need to clear cache files for apps regularly? Like clear it once every 3 days or once a week?

    - I've read somewhere that android needs more RAM in order for apps to run faster and load up faster the next time we use them. And more RAMS would be better as long as it doesn't get too low. And using task killers/managers are not so good for android unless we're using it to stop some buggy apps. So is the cache files the same situation as the RAM?

    - Is a battery saver app needed for new android phones or tablets? Like the Juice Defender app? Am a lil worried that the battery saver app might dmg the new battery since its still new and can last like 2 days with 3g + surfing the web + games.

    Any advice would greatly be appreciated. Thanks in advance.

    clearing cache is a good idea to do atleast 1 time a week. However that is my own preference and nothing that is a concrete evidentual thing. Cache is stored in its own partition. As far as the rest I just got my nexus 7 here the other day so I charged it twice now. Battery seems to be fine as is. The nexus will do a much better job at managing its ram then any app can so let it.

    I still use a cache cleaning app long after Eclair / Froyo etc. I have it set to auto run every 12 hours just before my commutes. I certainly noticed the difference with a well behaved phone back then; perhaps I don't need it so much now on ICS but the notification shows how much space it freed up so no reason to uninstall it!

    I'll never touch 'task managers' however as android manages it's own processes. Once a month I might go in recovery & clear dalvik & what not.

    Thanks for the quick reply. It helps alot... Guess I'll 4get about the task manager and RAM and let it do its job. The RAM never really went down that much the most is at 400mb. That's a good idea to clear cache once a week lol... Gotta keep myself away from pressing too much clear cache option in the Nexus 7 lol...

    Anyway, do you guys use any battery saving apps like Juice Defender? If Im nt mistaken the latest comment for the app in the playstore was like 1 year ago... So Im thinking that maybe everyone else had moved on to a better battery saving app?

    It's a popular app, so must do alright :) .

    Most battery savings come from turning off 3g / data / sync when not using internet, keeping display brightness & sleep settings as low as you can bear*, & other things like haptic feedback, animations or live wallpaper off.

    *There are further tweaks if rooted, such as voltage / cpu settings & the automatic light settings. Often this comes with custom roms.

    settings>storage>cached data

    You can clear the cache out of all your apps from there apparently.

    I have a WiFi only N7 & I never take it out of my home.
    When I installed the free version of JD, my battery life actually went down!
    Via the link of this app in the Play Store, I went to the developer- Latedroid's- site & put in a query as to why this was happening
    I got a prompt reply from the developer & I then uninstalled it & my battery life came back to normal.
    Reading other feedback on the site I saw that the persons benefiting were mostly smartphone users; I didn't see any N7 or other tablet users.
    Maybe because a smartphone is carried around everywhere by the owner, unlike a tab.
    And a smartphone is used for many purposes-voice,data,video,GPS,bluetooth streaming of music to the cars' stereo,messaging,social networking etc.
    The JD & that too the Ultimate version, which is customisable really helps in managing all of these battery draining actions automatically.
    So, JD may not be of much use to you.
    As to how to stretch the battery life, there are many tips, in this forum & elsewhere on the net- just search for it.

    Thanks for sharing. Yes I've tested JD on my friend's Galaxy SIII and the 1st thing I notice was the battery life went down very fast even for android phones. It was on 4.1.2 Jelly Bean. Guess I'll just find another battery saving app or don't use one lol...

    Btw, when I go into settings >> battery, I can see that my screen is using up the battery like 66%. Is this normal? I've auto brightness set on and nw I've closed it and put it on minimum brightness.

    Thanks in advance. :D

    Yes, its normal.
    If your usage pattern- reading, browsing,watching videos-requires the screen to be on,it will be the biggest drain on the battery.
    Re brightness, its best to turn it the minimum on the slider bar- the minimum is quite adequate for most purposes & will give you significant battery savings, much more than the Auto brightness setting.Also, keep the screen timeout to the minimum- I keep mine to 1 minute.
    Apart from this, keep bluetooth, GPS off until required,set the Wifi & 3G to go off when the tab sleeps,turn off location services wherever you can,go thru the settings of every app except the system apps , and turn off automatic/background syncing & Notifications.
    These actions should give you good battery life ; I get abt 10 hrs between charges, with my usage patterns.

    Well that's a relieved lol... Yes I do browse alot and watch videos as well as play games on my Nexus 7. Already set the brightness to lowest and kept the screen timeout to 30 seconds. Pretty much did the same for the rest . I get like 8-9 hours for facebooking, browsing the playstore and playing some games on it lol...

    And there's 1 thing that I noticed. When I play games like SAS3 Zombie Assault, Dead Trigger the Nexus 7 will get hot. Isit ok? Because I heard somewhere that one of the good things about Nexus 7 is it will nt get hot that easily. Thanks for your reply anyway. Appreciate it.

    Yes, its normal.
    There's an app called Better Battery Stats+ ($2.90 on the Play Store) which I have installed on my N7. One of the data it yields is CPU frequency.
    When my son plays games- I don't- the Cpu freq hits the limit of 1.3GHz; esp with Intensive games, the cpu heats up the max; otherwise it just coasts along at a much lower freq for reading/browsing like activities,using just 1 or 2 of the 5 cores of the chip. Since theres no fan inside the tab, the heat is dissipated thru the body- the tab acts like a heat sink.So, don't worry, just enjoy the games!
    BTW, here's a link that will guide you to get the max battery life out of the N7.
