[TIPS] - for Performance and Battery life for G2 mini - LG G2 Mini

Tips for better performance and battery life of your phone.
Hi guys. I have decided to reopen this thread and share some of my tips to you (thanks to forum moderator). You find here basic easy tips, but also something more difficult. I do this specially for less experienced users, so any suggestion from others I will appreciate.
So let's start!
For performance:
For non-rooted devices
So, here, I can suggest you only keep your device clean. That mean, unnistaling unused applications, clearing cache, close recent apps. I don't believe any ram cleaners/boosters, because in most cases, they slow devices by running like process, instead they're helpful.
For rooted devices
Here we have a really more possibilities but also keeping clean device is a best option. When you're rooted, you can removere bloatware, or some preinstalled apps, which you don't use (recommended app Link2SD). In Google playstore exist a lot useful apps to get more from your device. My favorites are Root Booster and Kernel Audiutor to set up your device. In addition, on xda exist a lot of good threads for G2 mini, which are helpful. To increase multitasking you can use virtual memory - swap (If this method didn't work for you, you should try THIS). But, best options below.
For rooted&unlocked bootloader&TWRP installed devices
IMPORTANT! - before any modification have nandroid backup!
If you get here without any brick, now you can get most of your phone. So, here you can flash mods/tweaks to increase your performance like L SPEED MOD or ABS (for me best mods). It's good to try some customs roms (find here) or also try good kernels,which support zram (in my opinion better than swap). Just, do some research!
For Battery life:
For non-rooted devices
I'm repeat myself, just keep cleaned your device. Here is important to have a fewest background process as possible. So try don't use battery hunger apps. You can find apps which are draining your battery (in settings or use app Wakelock detector) and at least disable them. From battery extended apps i can suggest you Greenify, which is in my opinion the best effective app for battery. But don't forget, battery also depends on your usage and your brightness level.
For rooted devices
Still remember, what i write above. Here is it similar like in performance section for rooted devices. What's more, in stock rom I recommended download app Kernel Audiutor and set your cpu minimum frequency to 300 mhz (don't forget to set on boot), because minimal frequency of stock rom is 787 mhz.
For rooted&unlocked bootloader&TWRP installed devices
Here I can suggest you this thread. Also Xposed with some modules can be helpful. When you have custom kernel, I recommended set governor in Kernel Audiutor on interactive (best) or conservative. Custom roms and kernels will be always good choice for battery life, just give a try!
PS: On XDA exist a lot of good mods for your phone, so just search them!
My results:
I get about 5 hours on screen with medium usage and two days battery life. Also I'm able to do pretty good multitasking ( For example seeing Facebook, chating, listening music without lags) and in Antutu Benchamark I get score about 22 000 .
If you have any ideas, suggestions, tips etc. , post it here!
I think, is everything, what i can give you.
I hope this was useful for you and it helps you.
Good luck, to get the most from your device!

Zdravo, brate, thanks for the advices but i have a question, my G2 mini restarts all the backgrounds apps for example if i write something in this window then switch lets say to chrome for 2 seconds the previous app just starts over. It's the only thing i hate about my g2 mini.

Hi that is wierd Do you do install something on your phone? For example some mod or app. Try find out it. Also, you can go to settings, developer options, scroll down and chceck your limit of background process Or find something, what could be wrong But be careful, what you change

---

I didn't even root it, i only have basic stuff, and i also didn't limit background processes. Same behaviour on both kitkat and lollipop, even with factory reset.

Hi everyone!
This is my first thread, so i hope that you will like it.
I do some reserach about perfomance and battery life, and i want to suggest you some tricks and advices.
Please read these instuctions carefuly, this is safe metod, but always can something happen. So, be careful. If you dont understand these insturctions, dont do this I'M NEW, SO LINKS DIDN'T WORK FOR ME SO I WILL NAVIGATE YOU. It's easy, don't worry
BETTER PERFORMANCE:
Lg g2 mini come with zram 215 mb, we will increase it to 380 mb using two files (98 swap data,98 swap system). This will help you to do better multitasking and you will have less lags. But dont forget, you are the boss of your phone, so if you don't take care about it, you will get lags. Of course, that you can get more zram using 98 swap cache file, but this didn't work for me.
What do you need:
1.root - I have d620r android 5.0.2 rooted with kingroot
2.busybox- download in google play
3.support init.d - in google write "uni init v1.0 apk" and download it from first link
4.root browser- download in google play
5.script manager - download in google play
6.scripts- write "uloz.to" in google and tap first link. Then search "98 swap file" (dont worry about this website, is verified slovakia download site )
7.diskinfo - download in google play
Instructions:
1. Make sure you are rooted.
2. Extract 98 swap file and put that two files on sd card. Also "uni init v1.0 apk" put on sd card.
3. Instal busybox, then reboot
4. install "uni init v1.0 apk" ,open it and install init.d folder, then reboot
5.install root browser,open it,give it root permissions, and make sure that in system/etc/ is init.d folder. If it exist, you're on good way.
6. use root browser and copy 97 swap data and 98 swap system to system/etc/init.d. Then hold finger on 97 swap data, find permisions and check all squares. Do same with 98 swap system.
7.install script manager,open it,give it root permissions (don't forget to tick browse as root) and go to system/etc/ init.d. open 97 swap data and tap on "su" and "boot" and check "is executable" and then, tap on "run". Do same with 98 swap system.Then reboot.
8 install diskinfo app, open it, and if you have swap 380 mb, congratulation, you succesfully increase performance of your phone But dont UNINSTALL script manager, because after that, scripts wont works.
Also, i recommended app seeder and link2sd (remove bloatware).
BETTER BATTERY LIFE:
Also exist some scripts for that, but i don't testet them yet
What do you need:
1. Greenify - download in google play
2.Kernel auditor - download in google play
3. Wakelock detector - download in google play
Instructions :
1. Instal wakelock detector and find out which apps are drain your battery.
2 Install Greenify and hibernate some "battery hunger apps" or uninstall that apps.
3 Install Kernel auditor and set up cpu frequencies to max 1190 mhz and min 384 mhz. Set these settings on boot.
4. Than go to cpu hotplug and uncheck it. (set frequencies will work)
Also, I recommended close recent apps.
You are done. I hope that this thread helps you.
Sorry for my bad english, iam from Slovakia.
Enjoy!

Hi, I really don't know why. My g2 mini work as swiss watch... Try install Lg pc suite to your computer and in right corner find "mobile" and run something like "repair mistake of actualization".

I've done it and i got just 315mb swap! Anyway thanks
Sent from my LG-D620 using XDA Free mobile app

Thanks. :good:

it's better to use cache partition instead of system or data because Cache has 900 MB where like 15mb are just used

hi yes, you've right, lags phone, but only when swap file is on sd card. This is swap file in internal memory, so speed of read of this swap is fast. Reactions of phone are improved and also multitasking I get better score in antutu benchmark too (19234) You have'right about swap cache but this didn't work for me, so you can try it

let me correct myself: it does not lag, it was just minute after reboot so that's why it could lag.
i got 600mb swap in cache so now i got 300mb for cache.
works like a charm, i recommend this af

Hmmm, i don't know, i don't have that problem, after reboot, iam able to use my mobile phone after aproximmately 30 seconds. Of course, that system must loading applications and other things, so it takes some time, but that is noting horrible, isn't it? Yes, swap in cache is really good, maybe is better, but iam repeat, this didn't work for me. When i run script 98_swap_cache_file_v300, a get some error about swap.img.
I have swap 380 mb and it is far better than 215 mb.
