WHAT IS POWER BATTERY ?
Is an application that has been developed Kisler to improve the battery and in which we can select a number of options available to suit our needs can optimize the duration of battery . The idea of ​​this application has been to combine options that are useful for battery management and in turn be simple to use for everyone .
OPTIONS AND WHAT BRINGS ?
To improve this consumption have a number of options are:
Battery Percentage : This section is intended to determine the percentage of battery from Battery Power shall act performing the operations described below, default is 15 %.
BASIC SETTINGS
Wireless Mode: Selecting this option turns off the wifi if you have it activated before entering in the range of battery action defined in the beginning to Battery Power .
Data Mode : Selecting this option disables the data if activated before entering them in the range of battery action defined in the beginning to Battery Power .
Sync Mode: Selecting this option disables the synchronization should have it checked before entering the battery range of action defined in the beginning to Battery Power .
Bluetooth Mode: Selecting this option disables the bluetooth if you have it activated before entering in the range of battery action defined in the beginning to Battery Power .
mode Location: Selecting this option disables the location should have it checked before entering the battery range of action defined in the beginning to Battery Power .
Silent mode : Selecting this option disables the sound / vibration should have it checked before entering the battery range of action defined in the beginning to Battery Power .
Led Mode: Selecting this option disables the LED notification should have it checked before entering the battery range of action defined in the beginning to Battery Power .
ADVANCED
Mode Range: detects a known and active wifi zone wifi to connect automatically or off when leaving the area. (Discussed in detail below).
CPU Mode: Reduces CPU frequency automatically when entering the range defined in Battery Power Battery .
CPU Maximum Frequency : Defines how often you will use the CPU and the CPU mode , default 540 MHz
OPTIONS SCREEN
Brightness Mode : Reduces brightness automatically when entering the range defined in Battery Power Battery .
Brightness Percentage : Brightness Percentage to be applied in the glow mode , default 0 %.
Dark Mode: Controls the brightness as if it were an automatic but with lower values ​​to making work less and reducing the brightness sensor
Pocket Mode: Turn the screen to remove the phone from his pocket and is optimized to consume less than the native rom
Notification Mode: If a notification arrives for a few seconds to pick up the phone turns on the screen without pressing the (must activate accessibility " settings / accessibility / power battery" )
Notification Time : used in the second mode is defined notification
HOURS SMOOTH
Hours Mode : Turn the hour mode to manage data and wifi connection at a time interval.
Week end mode : Activates the alternate schedule for weekend
Restore Links: Restore connections to turn the screen during the hours so
Disable Sensors: Disables the sensors during the quiet hours
Set time : Set the time and day of the week that will activate the quiet hours
PROFILES
These options are combined with profiles Cyanogenmod . Its operation is as follows:
Battery power gives you the option to choose 2 profiles ( of Cyanogenmod ) for that you must enter the name of the previously created profile in the " Settings / Profiles " on Battery Power (default is "Home" and " street" ) . In each of the profiles you can enter a range of performance Power Battery, for example in the profile " House " 15% if we select the profile " Street " 25% . This is so that the Battery Power switch profiles automatically change its range of action and will know when your battery should act removing the options that you feel is necessary . To enable the use of profiles with Cyanogenmod Power battery is made from the " Profile Mode " option.
If not select any profile or the profile used is not one defined in Power Battery percentage to be used will be the first that we have defined earlier .
DISCLAIMER MODE RANGE
This mode produces no wakelock , battery consumption or anything similar . It is designed to conserve battery power in the event that we get out of range of our wifi preventing the active connection be used and consumed without activating it when we get to a place where there is a known wifi stay.
To do this I have based on location through LAC and Cell ID , or put more colloquially by the position of the antennas.
In the picture above you can see a simple design of antennas and radios. Battery Power antenna detects how you are and if you are in your area or not. To do this the first time I conectéis the wifi zone start checking nearby antennas ( depending on the house may be affected by one or more antennas ) .
Once detected out of the range of action of these antennas ( this may vary ) check the state of wifi is connected and if it will be off. The opposite case is that when entering the range of a registered as a wifi access point antenna, wifi be activated.
In the case we are in the same location, for example our home and want to disable / enable wifi to not have changed position we can do like coming to a new area to choose a new wifi network , since disconnection / automatic connection is made just by changing antenna .
In the event that wifi is turned off before choosing a new wifi network you connect may be due to a crossing of antennas ( due to the change from one to another so quickly disconnection may occur ) and if the problem persists after several attempts the solution may be to move a few steps to avoid this junction or off the range mode temporarily to introduce this new wifi.
Advantages of this: It has no wakelock , maximum energy savings by not using the location network location.
Disadvantages: If you are traveling to a remote area of your home, but that you get that antenna signal , being detected as " known antenna " believes these at home and activate the signal . This drawback will very much depend on where you live each and the number of antennas that affect the area. As a rule in the city or area where a large number of antennas work better this way .

Based on 4.4.2 / KOT49H (Google & CyanogenMod)
ROM includes:
Stock Google kernel w/ init.d support (AOSP(non CAF) kernel support by default, MUST use CM kernel ramdisk) (enable CAF kernel support zip in FAQ)
Google Now Launcher
Working ART runtime
Deodexed system
Superuser
Busybox
and more
MODs included:
Tweaked system (Very FAST)
Raised contact sync resolution (requires resyncing of contacts if you don't factory reset before installing)
Battery % on status bar (thanks to Erhany for the code) (disable zip in FAQ)
Exchange security bypass (thanks to apascual89 for the code)
Relaxed MMS compression ratio (Hangouts & Messaging)
Colored notification icons (restore white icons zip in FAQ)
Enabled access to App Ops in Settings/Security
Enabled debug settings in Play Store

Notes about Battery Saver script
Can be used with any kernels that have init.d support
It completely eliminates the need for an application to set CPU speeds or profiles
Easily customizable - See FAQ for instructions
If Android Overclock, No-Frills CPU Control, Overclock Widget, QuickClock Advanced Overclock, SetCPU or System Tuner are detected, the script is ignored, so it will not affect them
Preset profiles are:
2.26GHz - 100-85%
1.95GHz - 84-36%
1.72GHz - 35-0%
And just an FYI, even at 1.72GHz, the phone still operates very well & smooth, it's the battery savings that are the real benefit

Running it since yesterday with great pleasure : fast and battery friendly :good:
This is actually a newer build of CM, so if you flashed the old one before the release, I would suggest you flash the new release build
Thanx Calkulin, for this rom
Did Camera Have HDR mod
Thanx
Whats up bro?! I see you have carried your bag of goodies through every device bro and still keeping things "buttery". Congrats on the release. good return to android to find you release on the N5. :good:
I'll give this a flash when I get home
Dammit!! And I just flashed your AOSP ROM. I am gonna give this one a run to see if I actually wanna use CM on the N5. I ran a few other roms including the CM Nightlies and wasn't too impressed. I am sure your's will though.
Is tethering on Tmobile working?

So, How is the experience with the Google Launcher with CM? I have yet to try the new CM 11 because I have grown attached to the new Google Launcher in KK.
I am nervous to flash something new as I have well over a month going on my current setup.
Thanks
@Calkulin
Didn't you say your CM rom is your daily driver?

Will Lockscreen Notifications be added to this ROM?
Sent from my Nexus 5 using XDA Premium 4 mobile app
@Calkulin - Great build. Using the VanirAOSP kernel with no problems and your init.d scripts are working fine with it. :good:
I have a couple of questions, if I may.
- How often do you think you'll be updating the ROM? / Any plans to use GooManager or the like for updates?
- What's the benefit of "relaxed MMS compression ratio"?
Cheers

The Google Experience launcher works fine - just as you would expect it to on stock. Swipe-right to Google Now and everything.
CM11 has been perfectly stable for me. It's maturing nicely now and I haven't had any big problems. If you're still unsure just make a full backup before wiping so you've always got that month-old set-up to go back to if you're not happy.
Glad your on Nexus 5, remember u making my et4g usable.
Found a bug, when a headset is plugged in you cannot change the volume. It will visually show (volume bar) it just isn't making the physical adjustments.

No mods. Did a full wipe before install, the whole 9 yards...
I posted in other thread, got confused. This ROM is fantastic.
Sent from my Nexus 5 using xda app-developers app
I'm always concerned about battery life of my phones, so I find this rom really interesting. And now I have some questions before I can decide to give it a try (sorry ): How many percentages do you expect this rom saves compared to stock or to CM? How many hours of SoT for average usage? Does the battery saving feature still work if I flash another kernel?
Thanks.
Loving the ROM just wish it had resizable nav bars

Thanks Mike for the great video review!
NEWS/HAPPENINGS
----------------------------------------------------------------------------------------------------------------------------
v2.15 - Added color battery text (configurable, see post 2) and reduced contrast "Android is starting..." dialog to reduce screen burn-in​
ROM/RADIO CONFUSION?
We developers are still getting a handle on exactly what changes were made in LMD47D, E, M, I and LVY57H and which radio works best for which carrier. Keep in mind that this ROM will run with any of those radios, just be sure to use the radio that is best for your carrier. You are likely to get service on any carrier using any of the three available bootloaders/radios but based on feedback in multiple threads and user testing, it is my recommendation that:
- T-Mobile users use the LMY47M bootloader/radio (flash via TWRP - thanks @scrosler)
- Everyone else use the LMY47E bootloader/radio (batch file: flash via fastboot - thanks @scrosler)
NEED A PROXIMITY SENSOR FIX?
MeanPop v2.09 now has the proximity sensor fix built in: you will not have proximity sensor issues with this ROM!
For those running other 5.1 ROMs, some users are experiencing problems with the increased sensitivity of the proximity sensor on 5.1 ROMs and are cutting, removing, or buying new screen protectors to fix the problem. This is no longer necessary! Just download my proximity sensor fix. It should fix your proximity sensor on any 5.1 stock based ROM. Installation is simple: just install your ROM and then flash the fix over top.
SECTION I: ROM SPECS
The clean:
Built on stock 5.1.0 LVY47H
Smooth and stable (I don't release betas)

More to come...
Changelog is in post #2
Problems?
Everything has been tested and is working based on initial tests. Since 5.1.0 is a new base, however, if you run into any problems, please just reply in this thread and I'll check into it.
Credit where credit is due:
As with any open source stuff, some of this work is my own and some comes from other sources. So in addition to my own work (mostly in the "mean" category), here's a quick thanks to those of you who contributed knowingly (thank you) and not-so-knowingly via open source 5 finger discount (thank you just the same: your stuff is good and that's why I used it). Sometimes it's not entirely obvious where the source started so if I missed someone, please let me know and I'll add you. Also, I'm careful to only include other work where the author does not specify any usage restrictions or has given approval. If you believe, however, that I've included something that shouldn't be in this ROM, please just PM me.
@scrosler: I started with your stock 5.1 LVY47H odex ROM, so thank you!
@scrosler for your help on the clear all recent tasks mod
Thanks @r4wOne for the MeanPop logo
Want my stuff?:
I list credits in the features section above and links to original works: if you see something credited there and you want to use it, click the link and seek permission from the developer I've credited. If you see something in this ROM and I don't reference some other source, I probably coded it myself. If you want it: take it and use it in your ROM, your theme, whatever you like. I just ask that you please credit me. I'm a firm believer in Android and open source so you don't even have to ask. Anything you see here... it's yours for just the price of a simple line crediting me. I always share as I believe that's the way we developers put the power in Android... and one way we can fight "the Apple brainwashing machine".
SECTION II: FLASHING NOTES
Below are some pointers on flashing before we get to the good stuff (installation and downloads).
Problems after you flash?:
PLEASE DO NOT REPORT PROBLEMS IN THIS THREAD UNTIL you've done a full wipe and fresh install to see if that cures it. I know I should really just do like most devs and proclaim REQUIRES FULL WIPE/FRESH INSTALL on every version. That saves me a lot of headaches but I know what a PITA a fresh install can be even with MyBackup or Titanium at your disposal. So it never hurts to try just a flash without a full wipe, but if you run into any HINT of a problem... anything at all... don't report the problem in this thread until you've tried a full wipe and fresh install first to see if that cures the problem!
Note regarding tweaks: don't flash tweaks or themes on top unless you KNOW the tweak/theme is compatible with the the 5.0.1 base
Flashing - a final note:
Use this ROM at your own risk as I won't be responsible for bricks or any other untoward happenings. I spent a lot of time ensuring that the stuff in this ROM is fast, smooth, and compatible. But... it always helps to have some familiarity with flashing ROMs to keep yourself safe. If you're starting from stock, be sure to familiarize yourself with the unlocking/rooting process (from other threads) before flashing this ROM.
SECTION III: INSTALLATION
Download links are below
Now to installation of the ROM itself...
Always make a backup before installing anything on your phone!
Make sure you already have the proper bootloader/radio installed: I recommend T-Mobile customers use @scrosler's LMY47M radio/bootloader (flashable ZIP) and everyone else use his LMY47E bootloader/radio (fastboot batch file).
On first install of MeanPop, do a full wipe (although if you are coming from a stock 5.0.1 or 5.1.0 base, you can try a dirty flash).
Subsequent updates: no wiping necessary BUT...
If you have any trouble at all, do a full wipe and then reinstall
Install using recovery (I use latest TWRP)
SECTION IV: DOWNLOAD
... you're gonna break it!
Don't flash any other mods, tweaks, or themes unless they specifically say they are built for (the latest version of) MeanPop or you WILL break features in this ROM and/or cause instability! While this ROM is designed to have the general look/feel of the stock ROM, it is highly customized under the hood and mods, tweaks, or themes not designed specifically for this ROM will cause problems. If you want this ROM to run perfectly without any issues, do not flash anything on top.
NEW releases (5.1.0):
Note: coming from MeanPop v1.x, v2.x (or any stock based 5.0.1 or 5.1.0 ROM for that matter): YES! You can dirty flash! But if you run into problems, please factory reset and install fresh before reporting issues.
Just remember to flash the 5.1 radio/firmware before flashing MeanPop v2.x.
Download from Android File Host

OPTIONS AND CONFIGURING:
(scroll down for changelog)
Options (flashable ZIPs):
Look in your /data/MeanPop folder
stock-nav-bar.zip - flash this to restore stock navigation bar height
stock-proximity-5.1.zip - flash this if you have no trouble with the proximity sensor on 5.1 ROMs and you'd rather use the stock 5.1 proximity sensor code
CPU optimizations:
If you are running a custom kernel, I would recommend turning off the CPU optimizations. Open /data/meanpop.opt and set:
CPUOPT="false"
Color Battery Text
If you would rather have plain white battery text instead of the default color-level text, open /data/meanpop.opt and set:
BATTCOLOR="false"
Configuring the LED options:
Flashing notification LED and user configurable color priority is now available:
- Use Root Explorer or other root file explorer and open /data/meanpop.opt and edit parameters to your liking
- Set priorities so your more important LED colors stick and are not overwritten by lower priority colors
- Priority 9 will never overwrite priority 8, priority 8 will never overwrite priority 7, and so on
- Keep all priorities set to the default 9 if you don't care and always want to see the most recent notification color
- Default LEDBLINK mode is "auto" = LED will blink as long as there are not more (different) color notifications "underneath". If multiple color LED notifications exist, the LED goes solid.
- When LEDBLINK is set to "true", the LED always blinks
- When LEDBLINK is set to "false", the LED will always be solid
- You can open /data/meanpop.opt and change the blink rate (ON ms and OFF ms - see last two lines in that file)
- Don't go crazy with the blink rates: I recommend keeping the on and off periods at 500ms or higher
- New: LEDCHARGEMS controls how long the LED flashes when charging (red = charging, green = full). Set LEDCHARGEMS=0 to disable charging LED flash.
Notes on native LED... should you use it?:
The native notification LED built into this ROM needs a wake lock to run the LED, but only when the LED is actually on or blinking. Even with nativeled enabled, the phone will deep sleep as long as the LED is off but when the LED is on (solid or flashing), a wake lock is acquired and your phone will use slightly more battery. The difference in battery usage, however, is minimal and the fraction of extra battery used to run the LED is well worth the feature! Even with the LED on or blinking constantly, your phone will typically use only around 1% battery per hour with the screen off/idle.
If you don't plan to use the LED at all, I would recommend opening /data/meanpop.opt (you can do that with something like Root Explorer), and changing this line:
NATIVELED="false"

Welcome Mikey! I ran nothing but MeanBean on my EVO4GLTE. Glad to see you made the move to Nexus device.

Power menu is provided in the included Quick Boot app. I find that faster and easier than using the power button anyway (plus it saves your power button) but my intent is to not code stuff that already exists. That way I have time to do the stuff no one has done yet... and I don't have to redo it every time there is a base update.
As for clear all, I personally don't see any need for it: let the OS do what it does. But if lots of people want it, I can look into coding it.
Mike
Alright downloading this finally
Welcome to this awesome phone!! This ROM sounds promising from the other comments I've read, can't wait to flash it!

ABOUT
ArrowOS is an AOSP based open source project started with the aim of keeping things simple, clean and neat, both for the Android system and users. We understand the pain of unnecessary and sometimes rarely used mods/features being shipped with custom roms nowadays which may end up causing battery drains and/or memory leaks & crashes. This is being strictly avoided on our side keeping everything to a bare minimum, delivering stable performance all the time without destroying the AOSP interface. With users getting more used to tweaks and features, we added just the right features and customisations that will be actually USEFUL at the end of the day.

FAQs
Q: VoLTE icon is missing! How can I enable it?
A: Settings -> Display -> Statusbar icons -> Enable VoLTE icon
Q: No dark mode in Phone and SMS apps!
A: Either install Google Dialer and Messaging from the Play Store, or enable "Override force-dark" in Developer settings
Q: Where is Dirac audio enhancer and how can I enable it?
A: Go to Settings -> Sound -> scroll to the bottom
Q: 2 Big cluster CPUs are always offline! Not able to turn them on!
A: When CPU load is low, these cores are turned off to save power. They will turn on automatically when CPU load increases. If you still want to turn on cpus disable core control in EX Kernel manager or a similar app.
Q: HELP! everything was fine until today but suddenly my screen stopped responding to touch and I had to reboot!
A: It turns out that k5/plus units with certain display panels have some issues with DT2W (double tap-to-wake) enabled. You can go ahead and disable it in display settings, the issue should disappear after that.
How to download this ROM?
I keep failing
Hi adityhya rom I use the way you say performance has increased really good rom now I wish you more success and new privatization plenty of roms waiting for you to meet us
I used this rom for a short time (I'm still used) It is very stable at the same time and curious item, the front speaker played ringing sound (too useful because my rear speaker is rusty)
Launchair bug does not open after reboot
And the battery consumption is very high, consumes a lot and it takes a long time to charge.
Other than that, great rom.
V smooth so far, it's the third day i m using this rom, no issue at all, the enhanced sound is v nice feature,
The battery consumption is a bit high, even in deep sleep
Thanks so much ,Good job ??
Dev kind request can you add rotate settings for rotating screen 270* because lower half of my screen doesn't respond so i have to use it in reverse
Please help
CPU core release does not work. After performing the procedure, the cores are momentarily unlocked but after a short time lock again.
Can i update it dirty ? Or it has to be clean flash ?
Is it possible to pass safetynet with this ROM and microg?
Thanks for the rom.
How can I turn up the volume on my headphone?
And the call recording option isn't working, you can't hear what the other person says
The phone freezes randomly from time to time and it goes to lock screen where I have to enter the password to unlock the phone
How can this be fixed
What causes it ?
Cast screen restarts the phone suddenly
Im using the last update 19-1-2020
It used to work with the previous updates
Thanks for still keeping alive this outdated device !!!!!
But i am missing Dolby Atmos that bassy speakers ....
I tried installing dolby from magisk module but the rom crashed. can anyone give me link for the dolby Atmos which can suppprt this rom...... Thanks for the rom
Poor call quality reported by person on other end of the line - A6020, Q, Arrow OS
Hi,
First - When I call or someone calls me, the voice of the person on the other end is loud and clear. But the person reports that nothing of what I say is audible. There is too much of noise, or a howling voice is heard from my side. The issue normally occurs when there's HD calling b/w me and any other user (And both have Volte active).
Second - Google voice typing, WhatsApp voice messages and voice recorder does not record anything from the microphone.
Third - Pls add a tweak for mapping hardware buttons in settings.
Fourth (And of very little need from my side)- Pixel Launcher crashes with full gesture navigation activated. Up to 2 button navigation, everything is fine except that from 2 button navigation, the Google app seems to stop working, often executing after a minute from being tapped on the icon and Google assistant doesn't activate.
Encryption worked for me, many thank!
First, thanks for extending the life of this model , second I have noticed that the battery consumption during use is high, I have activated the minimum, no application that works in the background, the only thing that installed extra was the magisk

Hello Everyone !!
I need help I bricked my phone , I was just going back to my stock rom then I am facing two problems ..
( I am not blaming this thread developer , I appreciate him for his work as I also used his ROMs )
Now my problems are :
1)-When I flashed stock rom using Qfil tool ,its showing baseband version unknown and I don't have any backup file for this ... So can I restore my baseband version.(does again flashing stock rom will fix it?)
2)-this is my main issue that my device is boot only when connected to charging. If I disconnect charger it suddenly turn off and won't turn on without charger...
And my battery is at good condition so I don't think its a battery problem.
Thanks for reading !!!
I hope anyone wil help me ...!!!

[APP] Alti/Barometer app w/ Tile, Auto Calibration, Notifications and More!

Introduction
Google's Wear OS lacks many things from competitors... One of these is a Barometer-Altimeter application. So why not building one by getting the inspiration from the best one out in the market?
Read the instructions before installation!

● Android version must be 8.0+
0 - If any previous version in installed, go to "Settings" > "Apps & Notifications" > "App info" > "Alti-Barometer" > "App Info" > "Clear data" > Confirm
1 - Download the latest .apk file
2 - Install the .apk with adb (tutorial on the third post)
3 - Start the app
4 - Grant the Location permission (optional but recommended, if you want the automatic calibration)
Done!
Update instructions
If you want to update this app to a newer version, uninstall the old version and then install the latest using ADB!
Detailed info about the app
Every 5 minutes a the app will get the pressure from the sensor and store the data.
The weather notification is sent if 4 hPa are dropped in the past three hours.
The trend seen in the barometer is calculated in the past 6 hours.
For the first 6 hours the trend is going to be inaccurate because it doesn't have real data to compare.
Altitude is measured using the barometric formula, considering standard the pressure of 1013.25 hPa.
Issues
Automatic calibration not working on Samsung watches. I don't have a watch to test and I can't fix this bug unfortunally.
Download
Changelog
1.11
● Changed the app UI to make it different from the original app
● Added "Advanced Settings"...
... and that's a secret
1.14
● Added manual calibration
● Fixed a bug involving calibration
1.15
● Added fully customisable units
Auto calibration of altitude - explanation of the physics
I think this is cool to share
Air pressure depends on your altitude, but since air pressure changes normally, the readings are not accurate if the instrument is not correctly calibrated.
Manual calibration can be done... but it's just not practical! Automatic calibration is instead much better.
Let's start with the barometric formula:
Ph = P0 × e^(-α × h)
with constant α = (M × g) / (R × T)
The app gets your location, then finds thanks to the weather API the pressure P0 at sea level.
Once found P0, I can substitute it in the same formula to finally find the actual calibrated altitude
h = ln(Ph / P0) / - α
Ph is now the reading from the sensor and h is the current altitude
The calibration of the altitude highly depends on how accurate are the weather forecast provided...
From my testing I had a +- 10 m which is considerably good, but it depends from place to place.
ADB Tutorial
1) You will need to install ADB drivers to your computer. Suggested tutorial --> [OFFICIAL][TOOL][WINDOWS] ADB, Fastboot and Drivers - 15 seconds ADB Installer v1.4.3 | XDA Developers Forums (xda-developers.com)
Assuming you are using Windows, you should find a folder named "adb" inside the C drive with some files in it.
2) Place inside this folder the apk you want to install.
3) Enable "USB Debugging" on the device you want to install the apk on. This setting is hidden inside the "Developer Settings", that you can enable by pressing 7 times on the "Build Number" under "Device Info". There are many videos that show this.
4) Open the command prompt inside the "adb" folder. To do so using Windows, just press Shift + Right Click of the mouse and then select "Open PowerShell Window".
5) Connect your smartwatch to the PC with the usb cable.
6) On the PowerShell type "adb devices" without quotes and confirm with enter. Make sure the android device shows a message.
7) On the device press "Allow always" (or something like that).
8) On the PowerShell type "adb install Alti-Barometer1.15.apk" without quotes and confirm with enter.
DONE!

Thank you so much! I'd appreciate a little review here in the comments after you test it so I know if there are some areas that can be improved
Especially the thing i'm most concerned is battery life so if you find problems you know what to do!
New update
● Fixed a minor bug involving a predefined value where for the first three hours of app running, no notification would display
● The altitude graph only displays rounded integers numbers, now is much clearer (no more spikes)
● Fixed a bug involving calibration
To update it is recommended to follow the procedure described in the original post

This project's purpose is to replicate almost identically both in terms of UI and functionality the Samsung Alti-barometer app, which is preinstalled on Samsung smartwatches.
This is the app I'm talking about -> https://galaxystore.samsung.com/geardetail/com.samsung.alti-barometer
I don't understand what you mean by beep sound (what's the beep for?) and location icon (you mean that the app should display an icon when it gets the location?), especially because I don't think the original app has these features.
Final Update
The latest update features a new UI for the tile.

Thanks for your work, Can we access the app from tile and the full app can keep alive (not close itself till we close it.)
from my Suunto 7
and the last quest why altitude num from tile not the same as app itself. (from my picture --3m & --1m)

1) Click on tile added
2) I managed to fix that.
NOTE: Your issue might also be related to always on. If you have always on disabled, after some seconds the display will lock. With this fix, if you turn your wrist (or click a button, or touch the screen), the app will return visible instead of showing the clock.
If you have always on enabled... No issues either because always on is supported and the app will keep open.
3) That's because the tile does not show real time data, while the app does.
This app collects data in the background every five minutes. This data serves for: pressure trend, notification alert and graphs. The value you see in the altimeter and barometer page are instead real time data, polled and computed instantly.
The tile shows the last collected data from the background service so what you see in the tile is at worst five minutes old.
It's not beneficial for battery life to have high refresh rate tiles... and for that there's the application!
Why v1.7 is not calibrated? please help. (After installed 24 hrs.) THANKS

This is strange cause I didn't change anything on the background service from last update.
If you followed the installation instructions from original post I'll suggest try checking again these things:
1) Go to "Settings" > "Apps & Notifications" > "App info" > "Alti-Barometer" > "Permissions" and make sure that "Location" is enabled
2) watch has to be connected to the internet, it doesn't matter if through WiFi, through 4G or trough your phone's bluetooth (so no airplane mode)
3) watch's location can depend on phone's location. Try checking if both are active in the settings (but I assume they both are because it worked for you yesterday)
4) as a last step I'll suggest to reboot... Most of the times that solves any issues
Keep in mind calibration is set every 4 hours so if one of these actually solved your problem you'll notice it after some time!
If it still doesn't work let me know because it is strange
Storm Warning Notification is OK.
we have 7 day Weather Forecast, During 3 – 5 Aug, people in the whole country should beware of severe conditions and stay tuned for the weather update. All ships should proceed with caution and should keep ashore including keeping away from thundershower bra bra bra...
and I 've trid to clean new installation hope auto calibration work again.
Altitude is not calibrated, does not calibrate at all, location permission is on, maps work, but altimeter says calibrated never.

I'll definitely have to check what's going on... However one thing that bothers me is that from the weather provider portal I can see that today were made 2 API requests... So somebody has this feature working. I'll dig more and update you if I find something. Also the fact that currently I don't have a phisical watch to test it apart from the emulator doesn't help
finally calibrated by V1.7 , after 4 hrs of Clean install . But don't known why minus altitude value.

Last calibrated was at 18:10 and the altitude +8 m should be more or less correct I guess. What happened in your case is that air pressure in your location increased as happens naturally during the day, tricking the altimeter to think that you went lower on altitude. Probably what's going to happen at 22:10 is a new calibration that should show accurate altitude. From my side I can't do anything about this, It has to do on how accurate the weather API are in your location and on how the pressure changes throughout the day. In days where air pressure is pretty stationary you won't notice it
Consider the altimeter value with a precision of 10 meters on raw value. Delta value (like if you want to measure how tall a building is) are precise instead!
News on the automatic calibration bug
I tested the app with the emulator and managed to fix that issue.
I'll try to explain what the problem was.
This app doesn't use real time GPS for location, it uses instead the so called "coarse location", that is based on cellular towers. The reasons are simple: the app doesn't need the metric precision given by the GPS, and "coarse location" is much less energy consuming.
Right after every reboot, the system location is a "null" value, meaning it is not usable for my app. At this stage the app couldn't calibrate the altimeter.
Then after approximately half an hour, the system location started giving usable values for the app and after that moment the calibration worked every single time.
So in conclusion, after a reboot, the app wants to calibrate the altimeter, but until the system location is not "null", it won't and there's no guarantee that the system will update it soon.
Solving this issue was pretty easy: I had to manually refresh the location right when needed.
Now it should work as expected.
By the way I moved the download link directly to xda attachments
At the time of the edit of this post I just reuploaded ver 1.8... I forgot to replace one thing I used on the debugging phase
I have found another bug. If the location takes a lot of time to be collected (which might happen), the background service will lock, showing a constant notification that is impossible to dismiss... This is not a normal behaviour and I will make a fix hoping that it will be the last.
EDIT: Updated

Thanks to @ZJRDroid for the help!
From yeasterdy, I started to try DerpFest R.
As I reported in another thread, I installed PixelExtended a while back and liked it very much,
But I think DerpFest R may be (possibly) even better.
I've checked the main features, and nothing went wrong.
VoLTE good, WiFi good, GPS good, Bluetooth good, FMRadio good,
Double Tap to Wake/Sleep, Face Unlock, MotoActions, etc. all works fine.
The most impressive thing is that the power consumption in the idle state is extremely low.
PixelExtended also had pretty good power consumption, but DerpFest R did even better.
Thank you very much leoxsys/DerpFest R.
I will continue to use DerpFest for a while.
PS.
It's a very trivial matter, but the only thing I was interested in ...
there is no free space on root partition(/dev/block/mmcblk0p53).
If possible, I would be very grateful there is a free area of about 100MB or 200MB.
(I want to put some font files to /system/fonts and modify /system/etc/fonts.xml)

Thank you very much for your reply, leoxsys.
I feel that DerpFest R is very well-balanced package.
If my wish("Want more empty space") breaks the good balance for ROM,
Please ignore it.

At the end of August, I was in a little trouble.
The problem is that the power consumption in the idle state suddenly increased.
I still can't solve it.
I tried several things such as clearing the cache, uninstalling the application, and restoring from the TWRP backup(I got it when there were no problems), but I couldn't get good results.
I tried again from a clean install. The stock state of Derpfest was left, and no additional applications were installed, but after updating various apps on the Google Play Store, the situation became a problem.
It seemed to get worse suddenly, so I suspected a hardware failure. I tried a clean install (& update on the Google Play Store) of ArrowOS 11 released earlier this month, but I was able to confirm that the power consumption was low, so I don't think it is due to the hardware.
So far, I don't know at all whether it's because of something in the app I additionally installed, or because I've made some settings that could cause problems.
If the same thing isn't happening to other users, I think I'm making a mistake.

When I tried "formatting the internal storage"(which I had never tried) and Clean-Install again, I was able to return to a good state.
I don't know the specific cause, but I think I made a mistake.
Thanks for make this, I want to try it but just have a doubt. if this ROM 32 bits or 64 bits?

Always 64bit and support for this rom is discontinued
It may not make much sense since the developers have declared "end of support" for this rom, but I would like to report what I have experienced.
In the previous post, I wrote "It was my mistake" because I was checking the operation with Airplane Mode turned on.
After confirming the initial operation related to Mobile Network, I checked the operation using only the WiFi connection without SIM Card. At this point, I set Airplane Mode "ON" to eliminate unnecessary communication processing load.
The problem was that Airplane Mode ON caused strange behavior around the Location Service, resulting in increased power consumption during idle state. (At the same time, the display contents of the "Battery Usage" graph also become strange.)
In Airplane Mode ON, the WiFi / Bluetooth Scanning settings in the Location settings and the Location Accuracy settings in the QS Panel did not seem to work properly (does anything go wrong?).
Even when Airplane Mode is OFF, I later noticed that the power consumption during idle state is extremely low and I saw it changes at around -1% / 1h.
Thank you very much for providing this ROM, Leoxsys

Thank you for sharing your thoughts about the ROM. I'm on DotOS for quite some time, someone in Telegram group suggested it for good battery backup.
On my other device (RN10P) I have DerpFest and really love it. So wanted to try it on Moto G5 Plus, but did know if it exist.
After reading your positive feedback, downloading it. Let's see if it's better.
Have you tried DotOS? What's your opinion?
Derpfest is simple and clean,
DotOS is more Modern UI than Derpfest.
I personally like a simple UI.
and I think that Battery Life is depends on what app you use.
Derpfest, DotOS, crDroid, ArrowOS, etc.
All custom ROMs were very special and very good for Potter.
Unfortunately, many ROMs for Potter has been discontinued...
and I currently didn't use potter.(very long time powered off)
Could anyone please say something about SELinux in DerpFest R?
Saludos y buenas noches... las Gapps están incluidas ...que bueno !
