How to increase performance and battery life on your Tab 3 (ideal for beginners)

Hi guys. I have been on android since 2011 and ever since I have been modding my phones and devices. One thing I found out is that when you pack your device full of goodies and games and apps, your device can start to get laggy and the battery drains faster.
As for the Galaxy tab 3 I saw that it gets quite laggy when some apps are installed....
Here's what I do to manage and Maintain my tab:
Battery life:
1.) The number 1 thing I do when I unbox and setup my device is install Battery Doctor.
-This app I found charges your device in a certain way to prolong battery survival and it does it in 3 steps.
-This app also has modes that you can turn on that you can customise to a setting of your desire.... it comes with 3 as standard. Extreme mode and super saving mode helps a lot when your not using it for a while.
- Lastly it has optional widgets that you can put on home screen that optimises the battery, cleans apps/cache.
2.) Another one that you may find as useful is MobileCare. This app has a battery saving mode, App manager and Task killer if your are looking at JUST battery. This app offers a much simpler way to reduce battery drainage from the click of a switch power saver mode is enabled.
Performance Enhancing Apps
So to have optimum performance without rooting your device or overclocking here is what I use:
1.) MobileCare - As well as battery saving there a few other tweaks it has that I didn't mention above....
-Game Speeder- this basically give you a choice of the app you wish to run and it will basically optimise the app/game for you so it runs as smooth as possible.
- It also has a built in Antivirus/Anti-theft feature which also speeds and improves performance if there are viruses or ads slowing you down.
- Task killer- this app basically kills all apps and processes so the ram is nice and fresh.....1gb RAM can get packed sometimes.
2.) Memory Booster- This apps really helps as well.
-It features a Quick boost mode when you just want free space and instant performance.
-It also shows proof of it working in the form of a monitor and a diagram showing ram before and after.
-This app also features its own task killer and a boost log.
-This app is really useful because it comes with some really nice small compact widgets that you can do the quick boost function and task killer from a simple tap on the home screen instead of actually opening the APP itself.
Please feel free to add on to this list....I wrote these because they were the most efficient in terms of being able to use them seemlessly.
This thread is ideal for those who havn't got root access and want to maintain their tab 3's.
I will upload links Shortly.
edit-----I know the Task Killer mentioned dosnt kill ALL the apps and processes. However the point of that app is to close all of apps and processes that wouldnt harm your system if they were closed, so you have you normal open apps that need to be closed and then some background apps and clears cache etc.

Not bad, but rooting is so easy and you get much more control.

Yup.. But even after rooting... BAttery doctor really improves battery!

I use juice defender ultimate and du battery saver pro. Best battery saving app. The best contributor is lux auto brightness( paid version). Brightness is very crucial for saving battery. Ex. At night our tabs tend to be more brighter. You can even set the brightness for any light level your in.

LOL I totally forgot about that one. I liked that app for its quick features... most of it was paid though..

Task killers are useless and in fact do more harm than good. Android is quite good at managing its own memory and doesn't need the help. Task killers tend to stay in memory which defeats the purpose, and 99.9% of the time the tasks they kill automatically restart anyway. They are not at all necessary and should be avoided.

I do and also dont agree having task killer why? They dont kill every single app u wanted and thus free only 5MBs of ram. Most apps like Advance Task Killer do the job well but the app itself takes the memory which makes it a disadvantage having a third party app task killer but then they do free up memory very well. Until now I havent found an app which has very less ram consumption and frees up memory very well.

They already have a task killer/ram manager already built in.
Simply holding down the middle button brings up all your resent apps with the option to kill all on the right, and on the left an extension which shows among others a RAM Manager.

so laggy
Hi guys, I just got the tab 3 8.0, and I like most part of it but the performance is seriously bad..I have restored ask my apps from Google server and while running apps and switching between them, I can't take all the lags it has. I just got it today so I can return it if I want but I'm wondering if rooting this device actually gains much performance improvements. I used to have a galaxy s2x, which has a similar if not worse spec than this tablet, and I don't know if I was running rooted version of touchwiz or not but the performance was pretty good. This tablet is much worse. A simple reboot fixes the lag but after a few hours, as I use it, I notice the stutters while using it. I just had a serious lag in Google plus app, it was stuttering so bad, but it came back to smooth after 5 seconds.
So installing the custom Rom available for tab 3 8.0 improve the performance significantly? I know there are not many ROMs for tab 3 8.0, so any user of this device just rooted the tab and tweak it themselves to gain performance improvements? Not just little bit, but a lot.
Thanks!

Mine is not laggy in the slightest, in fact it's quite zippy. Instead of blaming the device, look at your apps. It's possible one of them is the culprit. If a reboot helps, it sounds like you have too much stuff loaded in memory. How much free space do you have?

I know what you guys mean...... I know they dont kill all the apps....BUT it still makes a difference.....even if it kills off 200mb of cache and apps.... It makes a dramatic improvement to performance if you are running on a a stock rom! Not all of the task killers work as effectively as eachother I admit but some apps are really good for a quick time boost

I'll chime in. I always read that task killers are useless, because Android inherently does a good job of managing memory or what not. I personally dislike Android's autokiller; the more RAM you have the more it will work non-obtrusively, but it generally has a tendency to kill apps I don't want killed, when they don't need to be killed, and it does nothing at times to kill apps I don't want running.
What I do is I use Minfree Manager (I run it manually on boot, I'm sure there's a file somewhere you can edit which makes the app unnecessary)) to tweak the auto-killer, such that it doesn't kill apps except when absolutely necessary. My previous phablet, I used ZDBox to kill non-whitelisted apps every time I turned the screen on (and I manually killed whitelisted apps when applicable). This worked well and I only have good things to say about ZDBox, the older version was very lightweight and easy to use. Unfortunately ZDBox's task killer is incompatible with the Galaxy Tab 3 (at least my T211).
Thus far with the T211 I have been using Super Manager to kill non-whitelisted apps (like Google Play Services, etc) on standby. I am not sure whether it kills them, it only claims to "clean memory." Yes, they all start back up and memory usage increases quickly once again relative to the blacklisted apps, but this still prevents these apps from running non-stop and accumulating RAM usage, and even if that is meaningless, it at least serves a purpose by flashing a note in my status bar every time I toggle my screen on and off, regarding how much free RAM I have and how many apps are running. Yes the service runs in memory constantly, but that can't possibly be causing a problem because everything is fairly speedy.

I know what that guy means though..... I was running stock rom with stock kernal on my 7.0 and it was fine until I started downloading apps for it....It got to a point where no matter how much I overclock to performance it would still lagg even when i closed all my apps.
However I downloaded a custom rom with all these tweaks and now im running those same apps I had before running as sweat as a nut without even overclocking.:silly:

Hi mate, you are using my ROM, right?
I just quote, so other users get to know RocketTab as well...
And I'm still working on further improvements...

My Galaxy Tab 3 8.0 runs great from stock, but since rooting and using arshull's kernel (latest release) with the addition of trickster mod app, I am getting super snappy performance! With the ability to tweak cpu and gpu settings and build.prop tweaks I couldn't be happier. Battery life is good and I am a heavy user and lag is nonexistent in games, even some of the heavy duty ones.
BtW, a big thanks to arshull for his development with the GTab 3 8.0, and this forum and all its contributors! :good:

well keep in mind the 8.0 has an extra .50 of RAM. So that does effect the performance. I'm having the same issue. I have the S3 with 1.5 of RAM and never have any issues with lagging or apps running out of memory. Im wondering the same thing as the OP if a root would benefit this tablet in the way of performance.
If anyone has a 10.1 that they have rooted could you post any results or performance improvements that you saw from it?

Please give us the link of the specific app "from google play" and also please don't give ad.fly or something that makes us go to some advertisement first before going to the application place, Thanks.

Thanks for the guides.
Thanks . I will really help beginner to have keep an eye on their phone

S4 performance problems

My AT&T S4 is having performance problems. I have some lag/delay switching apps, or going to/from home screen, etc. But the worst is a game like Minecraft. It pauses/freezes/stutters every couple seconds when I move around. Minecraft doesn't have these problems on my Nexus7(2012)
How can I figure out what is causing this? I have searched for a CPU usage app but couldn't find anything. I read that looking at battery usage would give an idea what is using the CPU, here is what it shows:
Android System 43%
Screen 18%
Zooper Widget Pro 7%
Android OS 6%
Are these normal usage?
My storage space is starting to get low. Out of 16GB I have 1.17GB free. Can this reallistically cause problems?
I think I see RAM usage under running applications I see these big ones: NILS 120MB, Android L Keyboard 31MB, Tasker 19MB, WidgetLocker 55MB, Zooper 31MB. I'll try disabling some of these, but these are some of my favorite utilities

There are plenty of applications for speeding up your Android, such as Du Speed Booster and 360 Clean Droid. There are also some Xposed modules such as Greenify for doing the same thing (but better IMO). I also strongly suggest performing a backup and installing a custom ROM. I, for one, have noticed that the GPE ROMs are blazingly fast on my S4. In fact, in the next hour, I'll be releasing the 'Google Experience' ROM- it's based on Joe-Tech's GPE 4.4.4 for Safestrap and it's blazing fast on my phone.
However, I am not responsible for any damages your phone undergoes during the process of doing anything said, recommended, or even remotely implied in this post.
Best of luck! :good::good::good:

Thanks for the feedback. I don't have much time to spend with custom ROMs though. I had CM9/11 on my old Nook and tried to get something running on an older HTC phone a couple months ago. Just don't have the time or patience to go through all that. I removed NILS and that seems to have helped, still doesn't seem quite as smooth as it should. I'll check out Du Speed Booster and 360 Clean Droid. Thanks!

After looking at 360 Clean Droid and comments, decided against that one. Du speed looks cool Also found Clean Master Phone Boost has 100million downloads (really?) and 4.7 rating. I just wonder about apps like these, they almost seem like scams. I was really hoping for more of some do's and dont's of how to disable some unnecessary Samsung/AT&T garbage that might be wasting throughput/RAM.

Oh, sorry. I don't know how to remove bloatware while on Android- I just use disxdas kitchen when making ROMs, so I just delete the apps in their folder and repackage it. I don't know about removing them while on Android though. But I know for a fact that if you Google around you'll find some guides for removing bloatware off of the S4.
Also, 360 is my personal favorite- but don't fall for their antivirus trap. All Android antivirus are usually in general scams. They're known to make fake alerts so you can buy premium features.

(DISCUSSIONS) Battery life, performance experience, bugs ... after updating to 6.0.x

Here is a place to share your experience with MM update.
Discuss stuff like battery life, performance, bugs and other things.
Let discussions begin!

Battery life and stability is good so far!
First day on 6.0.1. I am happy so far with battery life and stability. About 5 hours of SOT and almost 24 hours of use.
That's great. No turning back to LP for me

better wifi connection on MM too. Just wish I had TWRP for it so I could make a backup

haven't had problems with MM yet, battery seems a bit better, Doze for sure improve stanby, rest so far stable and working as it should

Liking it for the most part. Stable, not met any bugs. RAM is good, battery seems about the same. Not keen on the new wallpaper settings style and the new audio wizard is confusing. I also got the beta version of the zen launcher - only slight visual tweaks really, but gives it a bit of a fresh feeling.

Bug: Every time I transfer a compile apk to install, it always takes me out the first time the package is corrupt but install the second test.
I had a recurring bug display after running a graphics-intensive application (it stutters) is resolved.
For the rest it's not better or worse than lollipop, autonomy is worth. This version brings nothing convincing.

better and better than 5.0.
RAM is so good

i have a huge problem with gyroscope and proximity. Both not working.

Anyone here experiencing bugs with the AudioWizard? It resets its config upon reboot?

Quick question, since I have not installed it yet. I assume it combines all your internal storage (system and internal storage) like Cm13 does? To me, it's one of the more important features. Having the 2gb/16gb US model, that gives me a lot more space for apps.
Sent from my ASUS_Z00A using Tapatalk

what CPU govenor does it use? Please tell me its not interactive (or that you get a decent selection at least).
If i use the standard 5.0.1 setup I go through around 4-6% of battery per hour, using tasker to switch off/on cpu cores and slow others down its down to 2-3% without a noticeable impact to performance.

Antutu benchmark result
63218 ! Isn't that great?

My experience with MM
Battery Life -
Since I am a new user, I cannot post screenshots here. Sorry about that. Overall battert life has been okay for now. Need to give the system about a week before making a judgement on it I guess.
Performance -
General performance has been quite smooth, but will need to test with heavier games to check RAM management. Normally, apps open almost instantly.
Bugs -
- Even after applying Super Saving mode (Settings > Power Management > Power Saver), I've found that window animations still exist, which was not the case with Lollipop.
- There appears to be a slightly reddish tint to the screen when Youtube video information overlay appears. Although the tint disappears when video goes fullscreen again.
As of now, these are the only issues I could find.

Don't think so. It still has "system reserved" space according to the storage bit of settings menu.

How much free ram do you have when you clear all the apps?

usually 750-850mb, which is not so different than before. The thing is that used to drop to under 300 and slow down over time unless you manually cleared, but now it seems to release RAM by itself properly. I can now forget about RAM.

i have Facebook and messenger app <3

Had my first weird wakelock this morning. Phone has been mostly asleep on my desk the last 4 hours, but battery stats show it awake all the time and with weird wifi behaviour too (I didn't toggle off wifi, but there is no wifi connection here).

I'd say the Marshmallow update was long overdue. Although I am really enjoying the beta release.
Bugs:
Android Pay doesn't seem to be working anymore, I'm getting the dreadful "Google is unable to verify" message when trying to add cards.
The notification bar jerks open sometimes, though that's a common issue in Marshmallow.
The latest Poweramp app isn't working for me. Can't tell if that's the app's fault or the phone. It did work before switching to the beta release.
Notes: Battery life looks way better than before, with almost no drain on standby in my tests. Other than that there's not much to say though I COMPLETELY hate that they replaced the Clear All Apps button with the booster thing that shows you how much RAM was released. I'm having to get used to just not clearing the apps anymore (though w/ the 4GB RAM model that's not too bad).

How to improve RAM usage and apps in the background

I have owned a Redmi note 3 for a while (Snapdragon 650 3gb RAM). I couldn't be happier with it. Great design, excellent development community, smoth, great configuration. I am really in love with it.
However... The only thing I hate about it is that it keeps on killing apps running in the background. Every time I switch apps, the cellphone reloads it. For instance when I am browsing in Chrome and then go to Whatssap to check something, then when I go back to Chrome it reloads the app... That turns pretty silly.
I know this has been discussed but I just can't believe this amazing device can't have better ram management.
Is there a workaround I can try to improve this? Like a sort of configuration or something? I am running MIUI. Eu rom with Radon kernel. Any suggestions would be appreciated.

Is it good in terms of gaming?

I have some problems, the first is when trying to install Magisk and Safety net fix, I decided to skip these steps, but after installing everything properly and restarting, it restarts itself and I go to the boot loader menu

It is a good custom ROM but ram management is very poor, it took half of the RAM, if I remembered correctly my remaining RAM was at 500mb+
In result, the phone is very laggy especially when you changed something on the homescreen. Please keep improving the stability and also RAM management because I really like the overall design of it too!
Also the model of the phone is I think Mi 9T
When you pull down the notification shade, its vey laggy too considering the phone is just ok in terms of its processor
