[Galaxy Note GT-N7000 General] sameer_tangri:
My Note GT-N7000 is blazing fast again!

Hi all.

I wanted to share my experience with all of you. I have been with the Galaxy Note for about 1 year and 3 months now.

Background-

Being an active explorer of XDA forums, it leads me to trying multiple ROMs (Custom, Stock and Leaked Stock-JB) on my Note.

To name a few, I have used multiple Stock ROMS (for India as well as other countries) and Custom ROMs (CM 9 nightlies, CM10, ParanoidAndroid, Criskelo, Kingdroid). I also used the recent XXLSC JB leak.

fyi...I have also been a victim of the infamous Superbrick bug. Luckily got my phone's motherboard replaced under warranty.

Situation upto 2 weeks back-

Over a gradual period of time, I had noticed that my Note started lagging a lot. Openeing Contcats used to take 5 seconds. Battery life was also greatly reduced.

The RAM utilization was always high, "System Storage" partition usage repeatedly became high regularly, even after deleting application caches (Google+, Instagarm, Facebook). This was clear from the Task Manager's "Storage" tab.

I flashed latest Stock ROM (for India) and also did a "Factory Reset". However, it just wasn't helping. When the Factory Reset didn't help, I was fed up and almost exchanged my phone for a Galaxy S3.

Action Plan-

Then I though of giving it one last shot. I installed Philz kernel, went into "Recovery Mode" and did the following steps which I got from another thread here-

1. Wipe Data/Factory Reset.

2. Wipe Cache Partition.

3. Advanced > Wipe Dalvik Cache.

4. Mounts and Storage > mount /cache /system /data /preload

5. Mounts and Storage > format /cache /system /data /preload

***Please be careful on No. 4&5.****

***DO NOT TOUCH*on /efs /emmc and /sdcard***

6. Using PC-Odin, installed the latest Stock ROM "N7000DDLRB N7000ODDLR4" for India and re-installed all my apps from Play Store.

I know the above is a long process with shortcuts like "Titanium Backup" existing. However, I followed the sure-shot way in my view.

Present Situation-

My phone is back to normal. It's performing the same like it was when I got it new. It's amazing. Battery Life is superb. Now I have also installed only minimal and required applications and games that I seriously like and use. No battery saver apps, etc. have been installed.

My applications launch immediately now. No lag whatsoever. Everything is superfast!

My Conclusion-

Based on all this I have come to the following understanding-

1. Limit installing of any and every game/application on your Note. It just doesn't help. Do research (youtube/google reviews) before installation. Install only the ones you really need and use.

2. Keep use of Live Wallpapers limited. AVoid them if possible. They hog both, memory and battery.

3. "Full Close" apps when you finish with them, i.e. swipe them off from the "Recent Apps" screen. This helps with memory as well as with the battery life.

4. You can keep regularly used apps in memory though. No need to full-close these. Try to limit this to 5-6 apps though.

5. Limit installing of Custom and Leaked ROMs.

6. If you do install Custom/Leaked ROMs, then try to follow the full cycle given above to get the best experience.

All in all I have found Stock OSes to be the best and most stable with good battery life. It's usually multiple/too-many apps that start causing issues like lag and bad battery life.
