[Q] Battery Life

Ok so I tried all of the following battery life tweaks:
collin_ph Battery Tweak
DecaMOD Battery Tweak
SetCPU
Overclock Widget

Click to collapse
collin_ph Battery Tweak didn't seem to work, I guess.
DecaMOD Battery Tweak didn't seem to work either.
SetCPU freezes my phone whenever I overclock it.
Overclock Widget works, but it doesn't seem to be working now.
One night my battery was ay 92%, I had Overclock widget on and had the Screen Off preferences set to as low as possible. I woke up the next morning and it was still at 92%. I thought it was really awesome, but I removed it to try SetCPU, SCPU froze, so then I reverted to OC Widget and it doesn't seem to be working D:
Any tips - tricks for SetCPU or OC Widget?

Collin's and DecaMOD are both "passive" apps, so you wouldn't really notice a difference, depending on use. At least in my experience. Did you enable profiles and set some up when you were using SetCPU?

You aren't using a bat tweak AND set cpu/overclock widget are you? If so, there is your problem. Never have more than one thing controlling your clock speed. One tweak or one app. No more

+1. No no no. Use one only

ah i have colin battery tweak and overclock but i get at least 11 hrs with both of em on. So to stop overclock just kill the app with task killer? or don't grant it superuser?
I just flashed colin battery tweak to see what it had to offer

You can just uninstall one of them. Look for 16 - 24 hrs of battery life. That's about avg. I would say. I get about 16 on fairly heavy use.

wake up phone quickly

hello guys I want to know in iphone when you click power button the screen turns on immediately but in Zeus 6.33Bn (also all roms I have tested contains stock rom ) it opens after 2/3 seconds some times if there is a lot of apps are working it take 5-15 seconds to open
any solutions ??

Why not using task killer ?

He mean: Why dont you close some unnecessary app?
and I don't see a big difference between 2/3s and immediately to wake up the phone ^^

I agree!
But using auto task killer will speed up a bit your phone.
If you want you phone even better, use supercharger script.

To my mind, it changes nothing or nearly nothing i use advanced task killer and im using it seldom, after charging only, or when i want to play some demanding game...
But, sticking to the topic, i would advice changing processor governor, what were you using? Are you using custom lockscreen like go launcher or widget locker?

I'm using zeus and it has the default ginger bread lockscreen and I'm on smartass2

Its quite weird, because smartass2 is rather aggressive governor. However, this long-time waiting (5-15sec) comes from lowering CPU frequency to really low, deep sleep numbers.
If its a real problem for you, you can easily increase lowest CPU freq and see if it changes anything. And second thing which comes to my mind, check in build.prop line "pm.sleep_mode=1". It causes device to get into deep sleep.
But, of course these changes will affect battery life... quite strongly :/

Trickster Mod app

Does anyone use the Trickster Mod app on stock kernel? I have the donate version and i take advantage of the charging LED light. If so what, if any tweaks did you try? I also use the multi core power save tweak set a 2. For anyone that may know, would using titanium backup to convert Trickster Mod to a system app have any advantages?

Doubtful. AFAIK Trickster mod just makes the changes at startup, it doesn't need to run all the time.
BTW I have both enabled, the multi core power saver and mp-decision.

Cool to know it works with the stock kernel. Is there a noticable difference in performance and does it give you better battery life?

It's tough for me to say if it gives better battery life due to a lot of changes in settings, e.g. greenify, app permissions etc working in connection. I will say it doesn't hurt. When my phone is asleep I lose about 1 to 1.5 percent per hour which is okay with me. Performance is fine for my needs. Plus I like the LED feature to know when my phone is charge by the status of the green light without having to psychically unlock the MX and check. But to say how much of a difference is hard to tell without setting everything else back to default and just using Trickster.

Battery Drain
Hi,
I have some issues concerning the battery drain. As I dont use the cellular connections, I turned on flight mode and enabled WiFi manually. I also setup the WiFi to turn off while the Tablet is in StandBy. Still I an loosing about 1% battery per hour. Within the old 4.1.2 ROM, this was far better. I just wanted to check if others experience the same and this is normal with KitKat or if there is some setting which ensures an improved behavior within deepsleep (asuming that my device will go into deepsleep,didnt check).
Thanks for all the answers and a big thank to all the guys behind this rom. I really like it!!

KitKat for our device is not a really good build compared to JB. I suggest you to try Ultra Power Saving Mode to reduce the drain caused by other apps and system services.

Yeah, I guess I could do that, but the ultra power saving mode has a gray scale theme and also only a limited number of apps which can be used. Thats like buying a BMW and then replacing the enginge and putting in pedals instead.
My guess is, that the device does not properly enter deep sleep. Within deep sleep, the device should not waste more than 1%-2% overnight.
How can I check if the device enters deep sleep?

I meant that you can do this to reduce the drain when you don't use the tablet. Anyway download CPU spy and check deep sleep. I suggest you to use greenify to freeze background services and improve deep sleep time.

According to cpu spy deepsleep has never been used. Is this a kernel issue? Is there any way i can activate deepsleep, mayby with an exposed module or app?

I also thought about a wakelock. Well greenify tells me that there are no bg processes to be stopped. I also used 'ds battery saver', which worked well on my i9001 and should force the device to go into deepslepp, which did not work.
I will have a look at this tomorrow. I guess i can use adb to check the wakelock (suggestions welcome

not my strong suit (I'm just a tinkerer, absolutely NO programming skilz).
Good luck and please keep me up to date, and I will look into it myself and compare to my stock build.

Hallo @smegg, which one is more stable, this rom or N8020XXUDNE4 v2.01?
What is the different between this rom and N8020XXUDNE4 v2.01?

[GUIDE] ROM setup after flash for better work

This is how I setup my rom after flash, and device is working very well with 52 installed apps
1. Configure settings
-Go to wifi and disable scanning always on
-Open mobile network and chose 2G (use 3G only when you need it)
-Go to more and then to mobile broadcasts and disable all (when it enabled, consume RAM)
-configure sound,display, and interface... As you want
-go to accounts and disable sync which you don't need.
-go to About and taping on blablabla, you know to enable Developer options and rom performance.
-Go to developer options set all animations(you have three) to 0.5
-Performance??
-you don't need it, I will show you in next step.
2. Flash this:
L Speed
Or make this manualy
2.1. Install&Configure TricksterMod
-For cpu freq the best is to set device default, like on stock rom, don't forget to press Lock freq.
-Minfree setup
-8mb
-12mb
-17mb
-25mb
-29mb
-33mb
-Syscontrol setup
-Set swappiness to 60
-Set vm.vfs_cache_pressure to 40
-vm.dirty_ratio = 90
-vm.dirty_background_ratio = 70
Set this from tricksterMOD
-CPU freq
The best is
-Min freq
320Mhz
-Max freq
1008mhz
-Scheduler
SIO
-Governor
SmartassV2 or SmartassH3
-GPU freq
-That is your choice min freq will increase battery life, but some laggs is possible, max freq will drain battery faster, but there is less possibility to have lag.
After all don't forget to set run on boot.
3.Install&Configure Greenify
-You already know Hibernate what you want expect Alarm clock, messaging apps, trickster mod, etc.
You already know if you hibernate app with push notifications, you don't get it.
4. Apps
-what about apps??
There is too much apps which user don't use, that apps use ram like other.
Now you need to delete everything what you don't use (live wallpapers, cm wallpapers, etc.) or change apps with some lightweigh, like gallery and keyboard. Download QuickPIC and google keyboard (lollipop themed) {{i will add link later }}
5.build.prop
-leave build.prop to default as much as possible.
-change DPI to device standard, in some reasons my device lag on 200, then I move back to 240 as default. This is for L7.
For L5, there is no line that define DPI, you can skip this step.
-Change ro.max.fling from 4000 to 8000 (don't add ro.min)
-Change vm.heapsize to 64m (I don't go under that, but difference is big from 128 to96 choose between 96 or 64
-Change lowRAM from false to true (you will get little more free RAM).
When you change it to true, you will lose transparent statusbar.
6.init.d
-keep device without any special tweaks, devs which make this rom, they choose the best.
Helpful tips:
-Don't use battery boosters, ram boosters and apps call like that. System do better than one app. There is low memory killer (lmk).
Also this app use ram which you maybe need for something.

Nice tips buddy!
Good job!
