Hi.

So these are my latest battery stats on Hacker kernel v12 (with Arrow ROM):

As you can see I am on the same battery charge for

just over 24 hours

!

I have been using Performance governors on both clusters

all the time

and Row with 512 at I/O.

No other kernel mods like undervolting and no Greenify, etc!

Please refer to the screenshots I have attached

.

In over 24 hours I only had 4% awake time and I still have 26% of battery life. These 26% equal to another 7 hours of battery life!

I also had a very high SOT (perhaps 6 to 8 hours or so) because I was very much online and using many apps also.

As I write Hacker kernel just got an update. The kernel still on v12 but it was implemented the latest Linux sources. This version is only available through the

Telegram Hacker Kernel Group

at the moment.

A past (unwarranted) infraction hinders my acceptance. .. Calling someone out for "tr*lling" 7 months ago!! Have to keep my "nose clean" for another 6 months. Probably won't happen. ..
[Galaxy S6 / S6 Edge Unified Development] fotis12:
These stats are great! What profile did you choose at installation of hacker?
[Galaxy S6 / S6 Edge Unified Development] Nimroth:
Could you maybe make a backup in Synapse and upload the .tar file? (maybe when v12 is officially released)

Do you use amplify, greenify? Settings?
[Galaxy S6 / S6 Edge Unified Development] NZnewbie:
Performance locks cpu speed at max. I cant see for me it would be good in terms of battery?.
[Galaxy S6 / S6 Edge Unified Development] Nimroth:
Was wondering that too, but his SOT on those screenshots made me curious :)
[Galaxy S6 / S6 Edge Unified Development] NZnewbie:
I hear ya
[Galaxy S6 / S6 Edge Unified Development] Nimroth:
[MENTION=5171262]droidbits[/MENTION] Your setup sounds pretty good. I am currently testing the config made by Indranuj Kar, but in couple of days i will try yours.

So I understood, that you installed the Kernel with stock profile and just changed the governors and I/O.

Since you are not using Greenify/Amplify I wanted to know if you are on full sync during the day (I am talking about email, whatsapp, facebook or whatever you are using) or are you switching it off and on/using an app to manage sync and data connection? I am asking, because the battery life you posted sounds great, but i don't want to sacrifice push massages etc.
[Galaxy S6 / S6 Edge Unified Development] bininga59:
Correct. During installation, the settings are all the same. The are you doing with Synapse.

In Greenify you need the donate version, otherwise the apps to sleep on.
[Galaxy S6 / S6 Edge Unified Development] Nimroth:
I think something went lost in translation here. I know the stuff about how to use Synapse and Greenify. But droidbits said, that he isnt using greenify and i wanted to know if he instead uses another app for managing sync/data.

[Galaxy S6 / S6 Edge Unified Development] droidbits:
Hi!

Well like I stated just above I do keep a close control on my screen brightness (never on auto-brightness!) and I turn OFF Wifi/Data Internet

only overnight

but the phone is on all night.

I mostly use Wifi (it stays ON all day until I go to sleep) than Data. I obviously keep the Data usage ON all the time when I am out and about.

I do use always the STOCK option on Hacker kernel installation.

Yes you are correct...most of the time (95% of the time)

my Sync is OFF

and I only sync as I find necessary. Please note that I do still receive notifications from WhatsApp, Telegram and Twitter on the spot even with Sync OFF.

You would not lose any notifications

. However I do have to

manually

only sync Gmail by opening the app and sliding down on the screen to manually update. This is much more battery friendly than Sync all the time.

I do not have apps like Facebook (

which I really recommend uninstalling Facebook due to the amazing amount of resources/battery used. It is just as bad as Google Services and they both have an unbelievable amount of Services

ALWAYS ON

!!!

) and if I want to use Facebook I do it through the browser which is quite a nice experience also and you are prompted on login for the 1st time if you want to receive push-notifications. So you don't lose Facebook notifications also.

So apart from WhatsApp, Telegram and Twitter I do not use other social applications really.

I do have Greenify (only installed ATM) but because I was "testing" v12 of Hacker, I do not have any apps hibernated at the moment but will do when I find the adequate Hacker kernel settings for me. Mind you that when I do use Greenify I do not hibernate all the apps like perhaps most people. I am of the opinion that you should only hibernate those apps that are active/running heavily on your Application Manager in Settings. I also will use Amplify (not installed ATM) when I flash Xposed in the near future. This is an amazing app with Xposed and it is worth making the donation in-app to unlock the full potential of this app!

Also I will be installing Disable Service (not installed ATM)

only to stop unused Google Services

.

If you or anyone wants a

safe list

of Google Services to disable with Disable Service application please click here

. :D

Just please read the

warning

on the post regarding GMail!

There is no real secret to it. It is as simple as I have described. In my most honest opinion this is the best kernel ever and we should be so thankful for having such a great Developer taking care of our phones and batteries. This is the only reason why my stats are possible on our phones. My only intention was to share in the thread

my personal experience

and stats with Hacker kernel and possibly help those who are interested...that is all.

I hope this helps you a little. :D

Hi! :D

Are you sure you have put the correct values as per list given?

Please

DO NOT

disable

ALL

the Feedback services! That is

BOTH Feedback Services

if you want GMail to function properly!

Please enable both Feedback Services and report back. The post where the screenshots are is now better explained for this not to happen again.

Thanks! :)
[Galaxy S6 / S6 Edge Unified Development] Indranuj Kar:
Please ENABLE "feedbackasynchservice" and "feedback service". If you want Gmail to work dont disable these two.

Just checked myself and [MENTION=5171262]droidbits[/MENTION] and the list works fine

FEEDBACK:

I installed on my 920k, recognized it as international version when flashing. But booted up correctly, everything seems fine.

Performancewise feels a little bit slower than Vindicator kernel (but maybe it's just me)

But everything seems to work as expected.

Gonna test controllers soon.

Thx for the amazing job.

Regarding your problem I just can refer to [MENTION=5564502]Indranuj Kar[/MENTION] and [MENTION=5171262]droidbits[/MENTION] already given explanations in this thread. Use V10, or V12 beta - which you'll find in the Telegram Chat - to avoid this!

Would you also like to share which rom you're using with hacker kernel?

I'm now on marshmallow beta but battery life drives me crazy. It's so unreliable.
[Galaxy S6 / S6 Edge Unified Development] droidbits:
Hi.

To start with I am on Hacker v12 but the most recent version of v12 which was very recently updated and it is just amazing!

I am using Arrow ROM v10 at this moment (which is very fast, snappy and great on battery) with the option Ultra Debloat at installation. This Ultra Debloat option obviously helps immensely with battery life.

I have last night decided to test another Hacker kernel setup (credits to [MENTION=5564502]Indranuj Kar[/MENTION] for having shared them with me although I made a very small change to his initial tip) so I am not on Performance governor anymore. The settings are very simple:

A53: Darkness governor and minimum clock speed at 200MHz and maximum at 1500MHz.

A57: Darkness governor and minimum clock speed at 200 and maximum at 2000MHz

I/O: tripndroid with read-ahead at 1024 kB and just below the read-ahead option I changed the I/O Profile from Default to Boost.

This is all that I am using to test with no other changes

at the moment

at kernel level.

If you would like some further information on my other methods of usage on how I also make my battery last so much longer please see my

post #1051

on this same thread obviously.

I hope this helps also other users of Hacker kernel.

Enjoy!

battery

Hey guys ,

I don't know if that's the right place to ask this but my battery life hasn't improved at all no matter what I do, I moved from stock to xtrestolite odexed then deodexed 2.4 and tried every kernel out there but still getting only about 3 hours of SOT . I have greenify(everything greenifed except whatsapp and FB messenger) amplify , powernab ,sync off,25% brightness ,google now off ,tinfoil for facebook and I'm on wifi and 2g . I still lose about 20% per 1 Hour SOT with light usage even with [MENTION=5545903]NZnewbie[/MENTION] settings . Anything I could be doing wrong ? or should I just accept the fact that this is my battery life and it won't get any better? :D
[Galaxy S6 / S6 Edge Unified Development] NZnewbie:
I use to use Xtresolite 2.4 and found it pretty average on battery. I changed to weta V13 debloated and It improved for me.

Its was ok on earlier kernels versions but the later ones V9 up seem to not play nice with the old rom bases???????.... I could be incorrect.

Yes you can but it is not supported by the Developer.

This means users do flash the kernel but until it is officially supported by [MENTION=5068852]thehacker911[/MENTION] you don't really get support...but you always get support from us guys! :D

[Galaxy S6 / S6 Edge Unified Development] Noxxxious:
All those apps will only improve idle battery drain and not SoT. Anyway you are not the only one. I lose about 17%/1h SoT and get 6h SoT max (average 4.5h) thanks to 0.2% idle drain per hour with amplify, Power Nap. Facebook apps drain ****load of power it's like having Google service drain.

Try Xtralite rom & hacker kernel v10 with battery profile. Use 6 cores max and set everything to battery with noop i/o. Give it a full cycle to settle and see what you get then

Just wanted to give some Feedback about battery life and Synapse settings. Big Thanks to [MENTION=5171262]droidbits[/MENTION] [MENTION=5832952]HTCNerdYoda[/MENTION] [MENTION=5564502]Indranuj Kar[/MENTION] [MENTION=5545903]NZnewbie[/MENTION] and of course [MENTION=5068852]thehacker911[/MENTION].

ROM: Arrow Rom 10 - full debloated

Kernel Version: 12

Other Stuff:

- Greenify

- 4G, Wifi and Bluetooth always on

- Always on full Sync (Inbox, Messengers, Xda, ...)

- Brightness always set to auto on lowest level
​

My personal goal was, to get the best battery life without loosing any functionality. My normal daily scenario (Mo-Fr) is 16h of usage, with 2-3h of SOT with texting, reading news, and making a few calls. Occasionally I am also playing some games, so the Settings should also be able to give some moderate gaming performance

First I went with NZnewbies Settings. They are one of the best to give you an awesome battery life. After 14h I still had almost 70% left with 2h20m SOT. Only downpoint was, that those settings gave me some lag while gaming and some apps started up a little slower than they used too. This is totally normal, regarding that it is absolutely optimized for battery life. I would still recommend it for getting the longest run-time.

After that I tried different settings, and thanks to Indranuj Kar and droidbits I finally found a setup that suits my needs.

I setup everything according to Idranuj Kar's suggestions. The only thing I changed was that I set I/O governor to tripndroid, internal_storage read-ahead to 1024 and profile to boost.

I also followed droidbits guide and disabled some unused google play services with DisableService (except the one for Gmail)

With those Settings i get ~50% of battery with 2,5h of SOT during my regular 16h of usage. This leaves me enough juice for night shifts and going on adventures ;) while keeping everything really smooth and making gaming enjoyable.

I am very thankful for all the input. Thank you again :good:

[Galaxy S6 / S6 Edge Unified Development] NZnewbie:
It would be worth a shot... least then you might be able pin down if its a rom issue or battery as previously mentioned.
[Galaxy S6 / S6 Edge Unified Development] droidbits:
Hi.

Well I really do not think XtreStoLite is the problem. I was on XtreStoLite Deodexed v2.4 for a while and I found it as great as Arrow ROM v10.

Of course this depends on many factors...what settings did you install the ROM on (Stock, Battery or Performance), how many of those "lovely" power sucking social apps you have installed, whether you are in Sync all the time, your SOT, and the list goes on and on!

Try and have a look at these two posts below. Have a good read, get some ideas and a strategy for your battery/performance balance. You should "never" go for one of the two. In too much battery profile you will lag a lot and in too much performance your battery will disappear quickly and perhaps you will be able to fry an egg on the top of the phone.

The secret is to find the right balance...and this takes some time to find out by trial and error.

Here are the two links I mentioned above:

I just want to spread a little light into all this discussion about undervolting and stuff.

To be honest: You won't get a REAL boost of battery life with undervolting nor a better overhaul experience. The only things you might get are lags and stutters.

This post is one of the best I've read about undervolting so far.

You should read this before even trying. ;)
[Galaxy S6 / S6 Edge Unified Development] NZnewbie:
My battery improved quite a bit with undervolting and using different governors. If I leave it as factory settings gov and voltages/cpu speeds my battery is what Id call crap.

I understand the articles etc but within reason the improvements are good enough for me to keep undervolting. I only see slight lag so it doesnt worry me. I also dont game or benchmark :).
