Once upon a time I had tried the lineage os 13 by gismoz and it was good, despite always having that drain.

Now I remember that I had installed on it the firmware that was flashed with the stock fastboot global developer rom. And that I did not use the firmware suggested by GismoZ. I was always used to reflash the full latest fastboot global developer rom before every custom rom that I have tried.

Now just for clarity reasons I want to explain what are the SYMPTOMS of our redmi note 3 pro's (KENZO):

An eccesive battery drain when the cellular data is on, that in the battery section is indicated by an extreme battery drain by the google play services.

Even when the phone is locked the cell continues to drain in an extreme way (2/3 % per hour) and even if the phone and the processor go in too deepsleep.

Now I have noticed that this drain goes away when the cell is in offline mode. Totally. The phone can do 13h+ SOT easily. And compared to the SOT with online mode, 4h sot, it's an extreme difference.

And about some weeks ago I have noticed that even with only the cellular connection on, without the data, it consumes an awful lot anyway (6h sot) always with the google play services drain higher than the screen consumption.

The antenna drain is super high.

This happens with stock MIUI latest global developer too now, not even on a custom rom.

----

So when I get back home in 6 days I will be trying los with the 8.2.4.0 extracted firmware! Hoping for the best!

Google play services is the culprit

I have been looking for a gapps less install for quite a while now and when I saw the thread, I thought why not give it a shot to see if it is the gapps or modem that is the culprit. I am using android since 1.6 so I know that google play services is a battery hog. And I know that google less install is VERY fast. In the days of 2.3, the responsiveness of phone without gapps was mind blowing. I have a samsung s5830i on stock rom without gapps and samsung apps and it runs as good as an average smartphone of today. It is that fast.

Anyways, I installed the customized Lineage OS build by umang96 without gapps and setup my phone. Of course, I still got whatsapp and all other apps that I normally would and I have aptoide store now, but no gapps and no ola cabs. I use a jio sim and I used to get around 2 days of use normally with gapps on Nitrogen OS as well as Lineage OS. I am using the phone with Customized Lineage OS without gapps for the past 3 days and my battery is still at 50%. That's a massive jump up. I am getting around twice the battery life. The responsiveness is also flagship level. The phone feels like OnePlus now. Trust me, install a ROM without gapps and you will see the difference.

There is one thing I remember from my MIUI days with redmi note 3. It is that MIUI by default kills every app and puts the device in deepsleep everytime you turn the screen off. I used to have frostwire or some download running in the background and when I turn the screen off , after 5 minutes, MIUI kills the app. Hence, MIUI kills play services conserving battery, something our custom ROMs do not.

Can anybody of you tell me how to extract firmware from other kenzo roms so I can try them with aosip to see if it makes a difference? [MENTION=7074986]Carlocarnev2000[/MENTION]
[Xiaomi Redmi Note 3 Questions & Answers] MrMagicPotato:
Ok. That's a good point that I thought too. But that is what evolution implies. I mean, google services are really useful, especially if we now live in an all google ecosystem. Since everything is based off google in this era (like emails, videos, photos, assistance and of course web search...).

MIUI is an ugly way of implementation because all of what you were doing suddendly gets wiped by the same system. What's the point of that? Start doing everything from scratch?

---------- Post added at 08:47 PM ---------- Previous post was at 08:39 PM ----------

If I have to be honest I don't really know.

I think that you could try with the ones shared by vkass or directly with 8.2.4.0 from the GismoZ's LOS 13!
[Xiaomi Redmi Note 3 Questions & Answers] aveemashfaq:
It is true unfortunately that most of the apps we use run only with google play services support. I mean I use olacabs whenever I go out and it needs google play services installed. Similarly with youtube app. But the good news is the development of IoT. This means that every service that we like to use comes as a webpage. The OlaCabs app now is replaced by a bookmark to the site. And of course, some apps have alternatives such as for youtube, I use skytube instead. Instead of play store, I use aptoide. So, that's good. I do not use other apps apart from that, so no issues for me. I am sure google-less install looks like a huge sacrifice to a lot of people and even for me, but once I put the hammer down for the change, it seems as simple as moving away from stock into a custom ROM. Not a biggie.

And true, MIUI has a very bad implementation. Anything I put in download stops when I turn the screen off. Even apps updating via play store. That is half the reason why I shifted out of it. The other half reason is that I could not remove some of the hateful in-built apps such as mobile tracking engine.

And by the way, has anyone tried microg and compared the differences. I think microg can solve all issues of incompatibility. I am too lazy to flash. I just setup my only device and will not be changing the ROM until atleast a week

By the way, this is a positive change that should help people. https://www.xda-developers.com/eu-antitrust-regulators-appoint-expert-panel-to-advice-on-their-case-against-googles-android/
[Xiaomi Redmi Note 3 Questions & Answers] TesterNotDev:
You, my good citizen, may have just cracked this case! This provides good explanation as to why MIUI seems to be more battery efficient (its not, its just more restrictive by killing apps).

A quick search in NOS thread and I come up with this. [MENTION=8230541]Nowowo[/MENTION], you might want to try it.
[Xiaomi Redmi Note 3 Questions & Answers] Nowowo:
Sadly, I already tried microg with unofficial LOS13 and omnirom 7.1 (has in-built spoofing) to see if the problem had to do with something like Google's constant snooping of location or sync or just Play Services, so I installed it and didn't add my Google account to the phone, but the drain was still there :( Thanks for trying to help, though!
[Xiaomi Redmi Note 3 Questions & Answers] MrMagicPotato:
Hey everybody... Do you think of moving this thread to news, guides and discussion section? Maybe it would gather some more relevance and we could get help from some good developers! Just for asking though...
[Xiaomi Redmi Note 3 Questions & Answers] TesterNotDev:
So just to clarify, you still get 1-2% idle drain even if you use microg on custom roms correct? do you get idle drain on xiaomi.eu or other miui based custom roms?
[Xiaomi Redmi Note 3 Questions & Answers] aveemashfaq:
Just wanted to show the battery life in the gapps-less environment. For the record, I am using Nitrogen OS with Radon kernel 5.1. I guess this shows how cool the battery life in a g-less environment is. By thw way, my usage is checking whatsapp every 2 hours for 10 minutes, check mails (half an hour a day or more) I commute to work for 20 minutes one way so I turn on mozilla stumbler and contribute my location to improving their services. I also make a few phone calls (10 minutes a day) and sometimes use my hotspot for half an hour. And then I get this battery life. The less battery you are getting is because of gapps. Microg is partly the solution but g-less install is the complete solution. The explanation is down below.

Gapps is really a nightmare. Firstly, it captures the celltower data all the time to update the google servers and improve the nlpservice. Nlpservice is the thing that puts a big blue dot as soon as you turn on the maps. The gps takes its own sweet time to refine the big blue dot into an accurate position. Then you get the proper fix. So, nlpservice is always capturing cell tower info to improve its service. Google play services also has the google cloud messaging (gcm) which updates the services very often. So, if you get a mail notification within 5 seconds of getting mail, it is gcm at work all the time in background. Apart from that, it also sends location info so that you can track your phone if it gets lost (android device manager). Because it provides you remote device lock in google, the device must sync with servers every second (I am exaggerating the "every second" bit). Apart from that, you have ok google detection that listens to voices all the time if you have enabled it. You also have google offering to backup all your app data so that if your phone is lost or master cleared, you can still restore all the data. You have contacts and calendar sync with happens often. Even your call log is synced so that it can be restored when needed. It also uploads your usage (of phone and the web in all browsers) so that it could make an online profile of your tastes, hobbies and habits and it can send you the most relevant ads. So, ya, if you are voluntarily building up your personality online on facebook, google is also running in background making even more advanced profiling of you.

This requires resources and thats how you battery is going. Microg is a step in the right direction because it takes away all the tracking and the freaky stuff and only puts the gcm thing so that you get the mail. Hence, microg is lightweight and faster, better and more battery friendly. G-less install is even more awesome. Use f-droid and aptoide. That is really enough for your needs. I can help out if you need any help.
[Xiaomi Redmi Note 3 Questions & Answers] MrMagicPotato:
So now I've started testing for battery:

My initial setup is:

Los 13 by gismo (with radon kernel 5.1 included) and open gapps installed

Everything runs on global stable 8.2.4.0 firmware

I will be monitoring battery with gsam battery monitor and look at the stats

Then I will switch to xiaomi.eu feel and see the differences

And do the same another time for the other two shared

[Xiaomi Redmi Note 3 Questions & Answers] {s3rious}:
This thread needs to get more attention by developers and users, thats for sure. There is obviously some bug or culprit that is sucking our battery to us, users in Europe.

Can mod please move this thread to news guides questions section?
[Xiaomi Redmi Note 3 Questions & Answers] aveemashfaq:
I am not using microg. I have a complete g-less install. I have just installed unifiednlp service from microg.

Hey, can't any person do the detective work like I did. It is not a dev work but surely an end-user experiment. Try a google less install and compare the battery life of that install in a custom ROM with the stock ROM of MIUI. Use the customized LOS by Umang96 with firmware 7.7.6 vs everything stock MIUI. You can download apps from apkmirror which are authentic. Just use armv8a 320ppi arm64 apps and report the usage. I think you will find the battery drain at par. If not, then it is the modem firmware causing trouble.
[Xiaomi Redmi Note 3 Questions & Answers] MrMagicPotato:
[MENTION=8230541]Nowowo[/MENTION] Could you request to move this thread to the guides, news and discussions section?

For doing it you just need to go to the desktop webpage of XDA and from there click the little warning sign that is below your first post, and then select thread moving or maintenance and write down the motivation for that (this thread needs more attention). I think that it could be a great move!
[Xiaomi Redmi Note 3 Questions & Answers] Nowowo:
Requested thread move.

Yes, I still get the drain on the custom ROMs I have tried, but I haven't tested xiaomi.eu since I only used it once as a base instead of MIUI to see if using its firmware with other custom ROMs made any difference (which it didn't for me).

[Xiaomi Redmi Note 3 Questions & Answers] MrMagicPotato:
But how thought?!? :crying:

You' re blessed or something:good:.

I'm on los 13 and I still get that drain.... Have the other firmwares to test though.

Could you tell me what is the configuration of your phone (how you installed it, what firmware you have and if you have some specific apps or something like that)? Thanks!
[Xiaomi Redmi Note 3 Questions & Answers] MrMagicPotato:
So in proof that it's not totally the fault of the play services and that it's the fault of something else in the firmware or in the modem, I have noticed that everything that uses a constant connection to the cellular data automatically uses an awful lot.

Take this for example: when I casually installed an app (called OperaMax) that basically is a VPN that compresses your data and send that back (making you use less GB of your cell data) it drastically consumed a lot of battery.

And so what you might ask?

Well, before I installed that app the play services were using a lot (just below the screen in consumption) and now, that I have Opera Max installed they are at the end of the list, consuming near to nothing. BUT GUESS WHAT? Oper Max, which controls the net usage is straight on top, where the gservices where before!

I'm still on 8.2.4.0 FW thought, I hope that things will change when I go to the Xiaomi.eu one....:eek:
[Xiaomi Redmi Note 3 Questions & Answers] {s3rious}:
I have noticed that too. When there is no other app that uses celular data, then google play services are at the top of the consumption. But, when there is some other app that is using your connection then that app is at the top of the list.

I have observed that when I mainly use wifi, google play services are at the top, but when I am using data then google play services are low.
[Xiaomi Redmi Note 3 Questions & Answers] Nowowo:
I guess if your theory is right, I guess the next step would then be whether it'd be possible to limit the impact through custom ROM coding, kind of like MIUI does.

I also noticed on 6.0 that the default e-mail app, which is not "optimised" in the battery profile, the same as Play Services, drained a lot of battery even though I never used it.

By the way, LOS14 got a power config update and the ability to use the newest modem from global dev this week. Has anyone tried it yet?
[Xiaomi Redmi Note 3 Questions & Answers] MrMagicPotato:
Since I have never used a Google less system (like a microG) I can't tell if my theory is right. Maybe if I install only microG or even nothing the phone will consume nearly nothing. Otherwise if that last chance experiment goes wrong, it will be a firmware bug that afflicts our phones.
[Xiaomi Redmi Note 3 Questions & Answers] MrMagicPotato:
Hey everybody you should all install gsam battery monitor so that we can compare are stats.

For example I get an extreme usage by kworker in kernel: there are like more than 30 instances of them running at the same time.... !!

And we should also send some logs to trusted developers such as umang and gismo
[Xiaomi Redmi Note 3 Questions & Answers] MrMagicPotato:
So hey everybody. After doing research I have found out that my phone, that I have bought from gearbest on july 2016, called redmi note 3 pro 3/32 GB, is actually a mess.

How did I find this out? I have checked the imei on the box that was sent with my phone and it resulted as a Redmi Note 3 MTK Chinese version with chinese bands.

But now you might say.. How have you installed all of the roms if it isn't a snapdragon kenzo?

Well. It is. It has a snapdragon 650, 3gb of ram and 32 gb of rom. But the problem is that it runs on international bands: the antenna is made to catch a bit of every signal worldwide because it has almost every frequency in it. But the problem is that it isn't optimized for none of the European states, it was an antenna/modem for the Indian/extreme oriental markets, not for Europe.
[Xiaomi Redmi Note 3 Questions & Answers] Nowowo:
I'm curious, I don't understand what you mean. Aren't Kenzos supposed to be like that (Asian market mainly) while Kates are the ones with band 20? How did you find check the IMEI for it to come as MTK (Hennesy was the codename?)?

Also, I've been testing the newest update of LOS14.1 with the newest global dev firmware and the drain is still there.

PS. I checked the official Mi IMEI verifier and it gives back 红米Note 3高配全网通版 深灰 32GB, which seems to be the Snapdragon Kenzo version from what I gather.

EDIT: Seems like we were moved back to Questions & Answers
[Xiaomi Redmi Note 3 Questions & Answers] {s3rious}:
This is exactly my situation, but I have bought the device from honorbuy in june 2016. When I check my IMEI, which is written on the box of the phone, this is what I get:

http://imgur.com/a/tc5j3

But, every app says that I have snapdragon 650, 3gb of ram etc etc.

And also, I've found that during the flashing of rom I somehow lost imei in the proces so I have to restore it now.

The thing is, I had very good signal in MIUI, what I cant say for AOSIP 5.9, which is based on CAF.

Could it really be that we have different antennas? Or just imei shows wrong information. I am really confused here right now.

Well, I am currently using the Brevent to save the battery, it can let some applications are no longer in the background activities, including synchronization, although there may be some trouble, but still a very good tool, you can use the Root mode and Network ADB mode to turn on the functionality (The best is the Root mode)

Has anyone tried flashing another firmware?
[Xiaomi Redmi Note 3 Questions & Answers] MrMagicPotato:
Hypothetical solution to drain

So, in the end, there is no good software or firmware that stops the battery drain. I blame mostly of that drain to antennas combined with the constant data and gps usage by google, because of the hardware and the software not being implemented properly.

The RN3 Pro SE (Kate) would be the complete final solution, because it has a phisically bigger modem, wich has more range capability and power, and also fully supports band 20 (800Hz), wich is the most widely used in Europe. Of course I know that it would be stupid to switch to the SE just for the band. And by any means it is now out of stock everywhere, you would be lucky even if you find it used or broken.

So the first solution that could really help (only partially though) is manually selecting the bands that are available in your place, and discovering the ones that are less used and more efficient. There is an app, that with root, is literally magical. It is called Network Signal Guru and you can find it simply on the Play Store and get to know the functionality HERE. There is also THIS app that helps you discover and sync better with antennas.

The second solution is to use a rom that is more efficient natively with the radio like AOSiP.

But I think that the overall best solution is to use the rr remix with Darkness kernel made by MOVZX, it has excellent performance and with latest builds it has fantastic battery life too! Then you can use the above mentioned apps to make the signal better, and get an overall good package. Also on the developer's TELEGRAM GROUP there is a full list of tutorials accessible with the #list command. There you can find its magic darkness kernel, his rr rom, the kernel control app and a tutorial to install microG apps with full playstore support!

The forth, but less effective, solution is to go directly kill-aura with brevent app, naptime and greenify.

Hit that thanks button if this helped you in any way!:p

PS: You can find what are the most used bands in your Country by doing a quick search on google!

Attached is an example of the bands that are mostly used in Italy.

[Xiaomi Redmi Note 3 Questions & Answers] Thanostsak:
I am a kate user and I have been on AOSiP rom (5.9 version which is caf based) for a long time. I have also been using the Network Signal Guru App with the bands used by my carrier locked on my device.I can confirm that these two have drastically decreased the idle battery drain of my kate. I am very eager to try Amplify when official xposed comes out for nougat,to see if it helps. However,there is still something "missing" from the development of this device that has to do with modem compatibility that you can easily find out on MIUI, but that's a sacrifice you have to make and luckily there are many great developers that still care about our device.
[Xiaomi Redmi Note 3 Questions & Answers] MrMagicPotato:
And that is a sacrifice for getting much more out of kenzo in general. We have to support our developers!

Regardless the modem problem, I don't think that is much a compatibility thing with development... With the redmi note 3 pro standard (kenzo), Xiaomi really tried to squeeze in the same modem, tons of bands, that are all much less effective. They did so for attempting to sell it on a global scale, but still maintaining the production costs low.

Then they built the SE, wich is 2 mm taller, for improoving the modem. MIUI is seems often better than custom roms because it aggresively shuts down everything when the phone is locked. I don't think that MIUI consumes less because of the modem optimization. Or at least, not that much.

For a demonstration, look at the nexus and pixel series by google... They all have big chins and bezels, but they have effectively the most efficient modems, in fact google itself has its own "Project-Fi" carrier program, wich when you are on it, your google device (starting by the nexus 6) can actively switch between all carriers bands and stations, without a hitch, giving you always flawless connection with, still, an excellent battery performance. [But nobody uses it because of the service price XD]

Another thing that I've noticed is that the charging port and power circuit are bad quality, during time they loose efficiency and make the phone get hotter, distributing power inequally. Even if I have never surpassed the 1800 mah charging limit. But I expected that because of the so low prices. [Or maybe my unit bought on GearBest was just plain sh*t].

By the way, I managed to break my kenzo's lcd (not the glass though :>, don't know how that could be even possible) and now I've fully disassembled it, and ordered a new screen on ebay... from china.... It will take a while.. A LONG while..! Cheers:fingers-crossed:
