[ZTE Axon 7 Questions & Answers] Oki:
It all depends on the mix of apps you use. There are some apps that are not well polished and they have too many wakelocks, or incompatibilities with some combinations creating too much battery drain. When you install more than 150 apps and you use more than 4 or 5 social apps along the day you begin noticing a huge reduction in your battery. Not to mention Spotify, Google app, Google fit, etc. Well know for keeping your phone from going to a low power mode.

As I said before, the culprit of all this problem is basically 3:

1. Wakelocks: avoid your device to enter into low power mode, this makes your phone to waste too much battery at night or when you are not using it for some minutes.

2. CPU throttle configuration: Default governors and schedulers are usually not tuned. The manufacturers do not pay special attention to this and it is critical for having a smooth device with good battery. The ramp up and down parameters are critical here. A good profile can provide you more than 10 hours SOT without any lack of performance. Sincerely, ZTE should pay attention to this since the hardware is much more powerful than just the default 5 or 6 hours of SOT.

3. AMOLED screens are very good at saving power, and if you have your theme configured in black then the screen can contribute a lot in expanding the SOT figure. Some people use the phone more than 6 hours per day and they require to apply those mesures. probably +1:30 H of battery juice can be the difference between requiring a power bank or the battery charger.

With this phone I do never have to charge it during the night. And the car charger during commuting to work is in excess enough for keeping it alive and healthy the whole day and night and with better performance when I need it. You do not need 25 apps to do so, and probably the package [MENTION=2720511]j77moduss[/MENTION] is sharing with us is excessive and for sure overwhelming to the standard user. Maybe not 25 but 5 or 6 apps to fix the 1, 2, 3 problems and another 5 or 6 to monitor the behavior in case of excessive drain is really common and can help you on extending several hours the SOT of your terminal while reducing the idle consumption.
[ZTE Axon 7 Questions & Answers] nolimit78:
Based on your numbers (even though they're anecdotal we can use them as a point of reference), that's giving you a 26% increase in battery with software optimization alone. I would say that's pretty damned good and worth the effort.

However, I do agree that getting 5:35hrs of SOT is pretty awesome straight out of the box. That's one of the first things that blew me away with this phone. All this power and you're getting 5:30 SOT. I light game, mid user with videos/music, but I have all my google/exchange sync to push, and have an Android Wear device connected pretty much all the time. So I expect to hit the battery a little harder than most users.

Another thing that stood out to me was the stock build. Granted, it's not as polished as some of your heavy hitters out there, but it also has a lesser footprint than most (I'm looking at you HTC and REALLY looking at you Samsung) Rooting and debloating the stock ROM has been absolutely perfect for me. I like to know exactly what my phone is running and honestly, it's worked out quite well.
[ZTE Axon 7 Questions & Answers] j77moduss:
Hello again, a suggestion like Lord Kelvin said "what you do not measure you cannot improve"

I have a suggestion to verify how is really running the best configuration and it is Untutu Battery test.

Maybe we could post our configuration and the Untutu result.

Any other suggestions?
[ZTE Axon 7 Questions & Answers] Oki:
I attach some screenshots of my battery evolution and stats for today.

Basically it drained about 1% during 5 hours at night. At work the signal is even worse and depend on the place in the building. However I spend a lot of time on wifi. At work and during the morning the screen was on for 8 hours while the battery level only drop 50%.

Extrapolating these values to a full battery level, the SOT is about 16 h

During the day I attended 3 phone calls and multiple Skype and WhatsApp calls. I used Spotify during the round trip commuting using Bluetooth. I browsed internet, I used XDA labs app, mail (tons of them), text messages, Skype, hangouts and WhatsApp messages. 4 pictures and I also had to install one app.

I only applied 4 tweaks to get this:

1. Optimized F2FS filesystem

2. Amplify

3. balanced AKT Xhana CPU profile (amazing performance)

4. Dark themes in several apps

All that using ZADmix7 ROM with stock kernel as the base system. I also enjoy premium sound with Viper4Arise that takes some CPU for the audio enhancement while playing music during commuting.

So yes, only 4 tweaks can almost triplicate the screen on time, increase performance and solve the deep sleep problem.
[ZTE Axon 7 Questions & Answers] amphi66:
Thanks for the in-depth analysis. Can you explain "Amplify", which of the 5 "Xhana Balanced" profiles you used & looks like you are fine-tuning an update to the application of F2FS? How will that change F2FS implementation for those of us that haven't made the change yet?
[ZTE Axon 7 Questions & Answers] JeromeLeung:
I think they released a new all in one script called AKT that only has 2 Xana and 1 Zhana profile. Simpler! :laugh:
[ZTE Axon 7 Questions & Answers] amphi66:
Thanks, I'll check again. I had downloaded the AKT just yesterday.
[ZTE Axon 7 Questions & Answers] Oki:
The one I was using yesterday was the Xhana profile. It is under the balanced submenu of the AKT command. It won't work on stock kernel unless you enable init.d support before flashing the AKT profiles ZIP. Regarding the F2FS optimization, please read the updated OP of that thread, In my latest posts in that thread I explain the procedure to integrate the mount options in init.d. The rebuild of the filesystem structure with optimized values is about to be simpler, since we are tuning the new TWRP 3.0.3-f2fs with backported F2FS drivers from Android 4.10. Do not use it yet since it can destroy your data partition if you use it as any other TWRP!!!! 3.0.3-1 is the safest so far. But you are safe if you already have a backup of your /data and /sdcard folders.
[ZTE Axon 7 Questions & Answers] amphi66:
Got it. I have HawkPepper, just above "Project'. The F2FS optimizations look interesting, but a bit confusing at this point. I used F2FS on my N5, but it was simply a question of having a kernel that supported, saving sdcard contents, changing structure from TWRP and copying tbe data back again.
[ZTE Axon 7 Questions & Answers] Oki:
Axon 7 stock kernel supports F2FS, so you just have to do basically what you did with the N5. However there are some mount options that can optimize the structure created during the data restore, and that depends on the F2FS implementation. There are also some problems with the encryption, this is why I wrote the guide for the Axon 7.
[ZTE Axon 7 Questions & Answers] Pollito788:
Do you mind sharing the Amplify wakelocks/alarms/services settings you have on your phone? Just bought the app, but have no idea what is safe to tweak without breaking the phone </3
[ZTE Axon 7 Questions & Answers] Oki:
I haven't limited the system too much. I do not want to get rid of receiving messages or limiting location services, so I allowed the wakelocks to be active every 180 sec. I limited: GCoreFlp, Location ManagerService, NlpWakeLock, AudioIn, bluedroid_timer, NlpCollectorWakeLock.

Same for alarms: com.droid27.twc.ACTION_TIMER_TICK, ch.bitspin.timely.widget.UPDATE_ACTION and com.android.chrome/com.google.ipc.invalidation.external.client.contrib.AndroidListener$AlarmReceiver.

I have not limited any service. I do not want to save battery while losing features.

I was losing about 1% through the night so I do not need to go very aggressive on Amplify configuration. I just force close Spotify after using it since I see it drains the battery when not in use. Amplify is not per-se a battery saver, it helps you on controlling rogue apps.

As you could see, the magic for saving battery is not Amplify, but the good tunables for the Interactive CPU governor and IO scheduler provided by AKT. These days I have been testing different Governors and I have found that BurnoutPR3 is best for benchmarks but for a daily driver Balanced Shana profile is awesome. With it I get from 10 to 16 hrs. of SOT depending on the high load time I put on the CPU (pictures, video recording time, youtube...).

I never charge the phone by night with the Axon 7 since I do not need it, all thanks to QC 3.0, I barely charge it in my car while commuting to work and by night, if I am under 40%, I load it about 25 mins to 70% and next morning while my 15 mins commuting time it reaches about 85-90% (never full charge it if you want your battery to last more than a few months). Short sessions of quick charge are healthier than long sessions to 100%. On the other hand do never leave your battery run out of charge or close to 0%. AccuBattery app can teach you how to get healthier charging habits.

Saludos
[ZTE Axon 7 Questions & Answers] Pollito788:
I appreciate the detailed explanation. Thanks a bunch !
[ZTE Axon 7 Questions & Answers] nolimit78:
Very very interesting. So given you're new ranges now, lets say you go from 83%-10% How much SOT do you have between those percentages?
[ZTE Axon 7 Questions & Answers] Oki:
Depends on the day, from 8 to 12 hrs. I am a heavy user at work and at home. Sometimes I use Waze in the car to go to other places around here and I do not charge it for two reasons. One, I do not need it, I do not use to be under 20%. Two, I try to avoid long charging sessions.
[ZTE Axon 7 Questions & Answers] greatzt:
I am pretty much a green horn on this forum. I want to intall AKT command on a rooted stock B29 rom. However, you said " It won't work on stock kernel unless you enable init.d support before flashing the AKT profiles ZIP. " Can you explain how to enable init.d support for stock rom?
[ZTE Axon 7 Questions & Answers] Oki:
You can use any app in play store, just search for init.d. I recommend Kernel Adiutor since it provides a lot more. Just go to the init.d section in the side menu, activate the emulation and reboot to have it working. Then you can reboot again into recovery and flash the AKT profiles.
[ZTE Axon 7 Questions & Answers] baconboy:
I downloaded Pixoff from the Play store - it turns off pixels to maximize battery life and is really customizable. Worth checking out!
[ZTE Axon 7 Questions & Answers] nuserame:
Thanks, I like it! I have it set only to activate when the battery gets really low (<15%).
[ZTE Axon 7 Questions & Answers] nolimit78:
So with all this, do you also leave the Smart Power setting on?
[ZTE Axon 7 Questions & Answers] Oki:
No, I disabled Smart Power.
[ZTE Axon 7 Questions & Answers] nolimit78:
So I've been doing testing and I'm just not seeing the same results that you are. So I have a few questions if you're willing to answer :D

1. Z.A.D.Mix7 when I installed the AKT zip from recovery it refuses to run. Like at all. I'll type in SU > AKT and it'll do nothing. Did you have to do anything special to get it to run in ZADMix?

Because of that I've been testing with HelsAx7.SubMix. I've been running a barebones build (AKT, magisk, Gaccount, Youtube, Exchange account, xposed and amplify) and I'm not seeing your results at all, however they are improved from stock. I'm currently on pace to get about 7SOT (using YT 10 hour video). Better, but not quite there.

2. Did you set any special settings in Amplify or did you just let it do it's thing?

3. When you applied AKT and you reboot the device, did you reapply AKT?

I've read that it may not be required but that it's a good idea. Let me know what you think!
[ZTE Axon 7 Questions & Answers] spacemanvt:
Bro could you go more in-depth on how to setup EX manager and this kernels?

I tried to follow your instructions but am lost.

Any help would be great
[ZTE Axon 7 Questions & Answers] Oki:
Installation is very straightforward. You need root for this.

1. Download AKT profiles 1.2 from https://www.androidfilehost.com/?fid=457095661767131857 to your phone

2. Reboot to TWRP and flash the zip file.

3. Reboot to system.

4. In terminal or ADB shell interface type:

su

AKT

Then navigate to the desired option. My daily drive is Balanced Shana, however it pretty much depend on your personal preferences and workload. You do not need to reboot after the profile has been applied. And you can switch to any other profile just following step 4.

Kernel Adiutor is not required anymore with this latest version since it now it uses su.d instead of init.d. This way it is easier.
[ZTE Axon 7 Questions & Answers] spacemanvt:
Cool i thought it had something to with EX Kernel Manager,etc. LOL

Anyways, I went ahead and applied it... Will post results after some testing.

Do these changes stick even after a reboot?
[ZTE Axon 7 Questions & Answers] Oki:
Yes, the profile is executed at boot along with the rest of script in the su.d folder.

By the way, the profiles only work with the interactive Governor so if you are going to play with ROM tuning utilities just mind that.
[ZTE Axon 7 Questions & Answers] nuserame:
I tried #3 an #4 with almost no difference in SOT, in fact even some of the more aggressive AKT Battery profiles had no effect other than making animations choppy. So I have to assume that the real SOT difference is coming from #1 or #2. Any tips about Amplify?

Or are you keeping your screen very dim? And maybe always using wired headphones instead of the speakers?
[ZTE Axon 7 Questions & Answers] Oki:
I posted my Amplify settings somewhere in this thread.

I use the auto dim. But it is most the time in medium settings. You can see that in the screenshots I posted. The test I did was at 50% without autodim. I feel Balanced Shana the best for me. However for max performance BurnoutPR3 is the choice. It all depends on your needs throughout the day.
[ZTE Axon 7 Questions & Answers] nuserame:
Well… I'm starting to wonder if I've got a defective battery. I've done everything, running AKT Balanced Zhana, 50% brightness auto, and I'm getting 2h of SOT. Almost no idle drain overnight.
[ZTE Axon 7 Questions & Answers] amphi66:
I note that this version installs to init.d & su.d. Any reason the init.d entry is still needed?
[ZTE Axon 7 Questions & Answers] Oki:
What a surprise. I only had the script in su.d. Probably because I deleted the previous version first.
[ZTE Axon 7 Questions & Answers] HuKu52:
There is an app AKT Profiles 1.2.2, no need to flash, no need for kernel adiutor, but possibility to return to kernel stock settings.
[ZTE Axon 7 Questions & Answers] amphi66:
FYI: Removed & all gone. Reflashed and AKT folder appears in /etc & 99AKT shows in /etc/init.d and also /system/su.d

Terminal install seems normal
[ZTE Axon 7 Questions & Answers] Oki:
Return to kernel defaults was there since the initial release.
[ZTE Axon 7 Questions & Answers] Oki:
They should leave the script in just one location. I had no time to install 1.2.2 yet.
[ZTE Axon 7 Questions & Answers] nolimit78:
Do you have a link to the app?
[ZTE Axon 7 Questions & Answers] amphi66:
Not an app, but a script. Post 31 above has v1.2. I haven't found the v1.2.2 referenced elsewhere

---------- Post added at 08:28 PM ---------- Previous post was at 07:54 PM ----------

went to look and didn't find v1.2.2, only v1.2
[ZTE Axon 7 Questions & Answers] Oki:
1.2.2 is finally an APK. You can download it from here: https://www.androidfilehost.com/?fid=529152257862697871

has anyone tried this is LOS 14.1?
[ZTE Axon 7 Questions & Answers] awsomjgp:
The power profiles? They will work on anything that has an sd820 and an interactive governor.
[ZTE Axon 7 Questions & Answers] nolimit78:
So when you apply AKT, how can you verify that they've actually applied? I'm using KA and EXKM and both don't show any changes when the app/terminal script apply.
[ZTE Axon 7 Questions & Answers] stojshic:
I tried it on LOS 14.1, stock kernel. Tried Zhana Balanced, and it really lags. Tried it for full day, got about 5hrs SOT, but it is lagging noticably. Anyone else using it on LOS? Did you install any other kernel? I notice few lines on install say something about kernel not supporting something (like touch-boost). Also, on one line it said non-lineage system, even tho I have Lineage... It might be possible that it interferes with Lineage's performance profile? It stays on stock here, which is balanced... Would like to use it, but dunno why it lags so much...
[ZTE Axon 7 Questions & Answers] Oki:
Yes, it works. I will try to post another SOT test in LOS and without Amplify.

---------- Post added at 19:53 ---------- Previous post was at 19:50 ----------

yes they are applied. Take a look at some of the tunable values before and after applying the new settings. I use KA.

New to LG G5, wondering if it´s safe to flash other region stock ROM on same model(and hardware, I guess).

For example, my H860 is TWN version(v20a) and would like to try SEA(v20b). Any thoughts/XP? 3G/LTE bands issues?

Thanks in advance.

[HTC Startrek] jockyw2001:
I have developed a method to *SIM* unlock the StarTrek. It works fine, see here.

I will not develop a program to find the codes. There are a couple of reasons: there are people who will use my sw to rip-off users on e.g. ebay; I have too little time to do the development; HTC wouldn't like the idea of me publishing a program using their intellectual property.

To find unlockcodes, I'm running firmware code in an ARM simulator. It takes about an hour to find the code and it's quite a laborous and delicate task to set it all up.

So I'm currently unlocking startrek, excalibur, vox and oxygen phones on a case-by-case basis. Contact me by PM and I will make you a reasonable offer.

You will have to send me 2 files which allow me to find your unique unlockcode. See description below.

Make sure your phone is application unlocked before carrying out these steps. In this post you find a simple description and program to do that.

1. run:

pmemdump -a 0xB002709C 16 docid.bin

This creates a binary file docid.bin. The tool pmemdump is part of the itsutil toolset by itsme, download here

2. run:

pdocread -n 1 0x000000 0x20000 -b 0x4000 simlock.bin

This creates a binary file simlock.bin. The tool pdocread is also part of the itsutil toolset by itsme.

Zip both files (docid.bin and simlock.bin) and email them to me. Contact me by PM first to get my email address.

EDIT

To easily produce the files unzip the attached Simlock kit on your PC and run simlock.bat (you should have an Activesync connection via USB cable). Two files are produced in the subfolder "1": docid.bin and simlock.bin.

Some pre installed applications can be uninstalled but system applications need root.
[Huawei Mate 9 Questions & Answers] JATCHUHAN:
Thanks but I already have root and unlocked bootloader but still cannot delete System apps. Is this because the system is encrypted?

I am interested as well.

And do changes to the system partition survive a reboot? I read about a guy here at xda loosing the modification of his platform.xml after a restart.
[Huawei Mate 9 Questions & Answers] JATCHUHAN:
Would it be possible to delete System apps by using adb commands on a PC?
[Huawei Mate 9 Questions & Answers] 5[Strogino]:
No. System is not encrypted.

It is because system (cust, vendor, ...) is protected by Android security (dm-verity).

Have tried at least 4 of these system app remover apps and all say uninstall successful but the apps are still there. Don't think we can uninstall system apps due to dm-verity protection of the system partition. Will have to wait for a developer to look into this
