RAM Utilization on Note 2

[raykau]

Hello All

I am experiencing some issues and would be grateful if some of you can share if you have seen this as well and if you have been able to fix this.

I have a Note 2 which I got in March 2013.

But the issue I see that the RAM utilization shoots up to 1.25-1.4GB/1.75GB quite frequently and becomes a laggy. I clear the Memory and this brings down to around 600-700MB and it feels a bit better but after only a couple of hours, it shoots back up again!

I am using only 5.18/10.22GB storage.

It would be extremely helpful to get some feedback on this and how I could fix this.

If you want to know any more information on this please let me know.

Many Thanks in advance.

Unused ram is wasted ram. If you want to know what's making your phone lag, keep an eye on your battery stats. Often lag is caused by something keeping your phone busy so it should use more battery.

You didn't give any useful info about your phone. If you're rooted and on a rom < 4.3, you should run lagfix.

Thanks colchiro

My phone details are

Model Number GT-N7105
Android Version 4.1.2
Baseband Version N7105BVDMF2

I did not root the device; just had an upgrade 3-4 months back pushed through the provider.

Also my battery usage says Screen using 27%, Android System using 17%, Android OS using 15%, these three are the highest users - are such stats normal? I have kept the screen with minimum brightness should it show such high utilization in such instances?

There is no normal, unless you never use your phone, then it might be easy to compare. Obviously screen at 27% means you're using your phone. Android System/OS could be anything. Since you're not rooted, there's a bunch of apps that you can't use to diagnose this.

Greenify requires root but would be excellent.
Better Battery Stats -- Might be able to use.

Thanks for your advice on this.

I check my battery stats every now and then by charging it to 100% before bedtime and in the morning I note how much it has discharged. Typically, with phone, WiFi and GPS enabled I lose anything from 3% - 4% over 8 to 9 hours. By doing this you eliminate some of the variables involved i.e. screen, phone calls etc

You can also check if it is one of the apps that you have installed that is occupying the handset and causing the lag, by starting it in safe mode and seeing if that improves matters. All the inbuilt apps and Samsung bloat ware will operate and sync etc as normal so in effect, starting in safe mode allows you to divide the problem in two i.e. their apps or yours.

thanks PiscesCloud

I will do so and see if there are anything I can find out. Thanks for sharing your experience.

My pleasure, I'd like to hear how you get on.

PS It just occurred to me that you can check what is using your memory by going to Settings > Application Manager > Running.

Perhaps you can spot the difference in RAM utilization there; a few screen shots may help with that.
