that's not the best method.
The file is created when you start the Phone.

There's no battery calibration. Do you research.

Exactly.
The "wipe battery stats" only deletes the file that contains the data about what used how much of the battery. The phone doesn't contain any "calibration" data related to battery, it's just an urban myth, deleting that file won't affect your battery in any way, only what's listed in the "Settings->About phone->Battery use" dialog.
For more info look at the following thread : https://plus.google.com/105051985738280261832/posts/FV3LVtdVxPT (or better yet read the XDA thread related to the issue : http://forum.xda-developers.com/showthread.php?t=1460553 )

AFAIK, ClockworkMod Recovery is not available for Milestone.
Alternatively delete it manually.
Search for batterystat in milestone forum there's a lot to read.....
Good luck,

Hi,
If you are root on your device you can use the terminal emulator to remove the batterystats.bin file yourself...
su [enter]
rm data/system/batterystats.bin [enter]
Beware, for the first few charge cycles your battery life may actually be worse, but it will improve. Ensure that you reboot straight after too.
Thanks for the tip.

Sometimes 100% charged is not really 100% but actually it is only 60% charged. This mismatch happens when flashing new rom. Have you done the battery calibration either using zeppelinrox's method
http://forum.xda-developers.com/showpost.php?p=11803458&postcount=10
or my method below:
Step 1:
Boot up your phone normally and charge your phone as how you would normally do until it says "charged".
Step 2:
Once your phone charging status says "charged", unplug the wall socket cable from the phone. Shut the phone off.
Step 3:
While the phone is still off, plug back in the wall charger cable. Switch on the power of the wall charger.
Step 4:
You should then see the M logo for a while and then it shows the 100% green battery icon in the middle of the screen.
Step 5:
Open the battery cover and pull out the battery and wait for awhile until you see the "?" icon in the middle of the LCD screen.
Step 6:
Put the battery back in.
Step 7:
If your battery is OK (properly calibrated) then it would show 100%. If it is not properly calibrated, then it would show 60% and it will continue to charge your battery until 100%.
Step 8:
Once your battery has reached 100% (while phone is still off), leave it there to charge for another 15 minutes or until the battery is no longer hot. When the battery is cool to the touch, it means the charger has stopped charging the battery.
Step 9:
Unplug the charging cable and do the "3 finger boot" (x button + camera button + power button) to boot into recovery and flash the new ROM.
Doing so will calibrate the new ROM to the current state of the battery as 100% charged.
Somebody actually posted a video of it... I think it was androidve.com
I should find it again and update my post hehe
Ah... http://androidve.com/2011/03/androidcast-episodio-ocho-calibrando-la-bateria/
ther aint ne folder called system in the data folder .. i cnt find the batterystats.bin file to delete
you can use clockworkmod on milestone
just copy update.zip to /sdcard/OpenRecovery/update and run it

yes correct measurement of voltage appear in 50% appear 3881
The adb measurement seems to be ok as the range is 3400 to 4100. U can get to recovery & wait / reboot till the voltage drops to near 3400. I have done this Eden faced with problems of battery on the stock ics twice.

first u need android sdk in your pc. download & install the same. it will be in "C:\Program Files (x86)\Android\android-sdk" in an 64 bit pc. in the command prompt go to this location. "C:\Program Files (x86)\Android\android-sdk\platform-tools"
from this point u can use the adb commands.
first check with the command "adb help"
u will get some responses.
u have to mount the system (in the cwm recovery) in the mount & storage section. then only will the device communicate with the pc in adb.
now connect the equipment (which is now in recovery mode) to the pc & use the command "adb devices"
u will get some sort of numbers instead of the 7300 or galaxy tab etc.
use the following command to know the voltage. "adb shell cat /sys/class/power_supply/battery/voltage_now"
pls note that there is a space in between "cat & /sys"
now follow the steps.
1. in CWM/recovery let it sit till battery in terminal will show less then 3700. The less you can get it the better. 3400 is probably absolute minimum.
2. shut down tab and let it sit for 1 hour. (this is needed for the first measurement)
3. plug it to charger and charge it for 5 hours.
4. disconnected charger and let it sit for 1 hour. (this is needed for the second measurement)
5. boot up your tab and test it, it your battery still not calibrated you can flash back your backup and repeat calibration procedure.
this is definitely a laborious process, but there is no option but to follow this.
hope this helps.

thanks alot
i did that using my current installation just need to mount system to work on recovery mod
i downgrade to 3.1 using 5 files and update to 3.2
and i did the previous instruction and the battery now is very good and no fake percentage
But still fake voltage even using adb
see the attachment
i think my be some fail in files measure voltage
today morining to disconnect battery for 10 minute but the same problem
any program for the battery show voltage in MVor 0.00? V
U can use battery monitor widget. Always good measurements & worth timeline also.
The second voltage from the s2 might be divided by 1000 to get the right value.

Common troubleshooting.

Hello and welcome to this thread.
Here I will answer some of the most common issues related to this phone.​
Q: I installed Nameless ROM v7.2 and...
A:
Change now. Its extremely outdated. Swap either to any CM10 ROM, Sensational V4, or Revolution. They are the most recent so far.
Q: What are the bugs in CM10 ROMs?
A:
Instant messenger voice messages;
Wi-Fi Hotspot.
Q: My WiFi keeps disconnecting.
A:
>Download this app
>Start the app
>Click on any of the non selected behaviors (Default or On During Sleep if plugged)
>The app will close
>Open the app and click on advanced options
>Enable workaround 2
>On the main screen chose Always on
>The app will close
>You are good to go
Q: My phone is stuck in a bootloop, what do I do?
A:
Did you install the correct kernel? NOPE only works on CM10.
Did you try a lower frequency?
Did you do a full wipe when installing a new ROM?
If the answer to all of these is yes, message me on Facebook so I can assist you.
Q: Can you implement [Name a thing] in your kernel?
A:
Help me find the patch and I will.
Q: How do I install a ROM/Kernel?
A:
Please read this carefully.
Q: What is the best ROM/Kernel
A:
There is no such thing. It has been mentioned a lot of times that this a dreaded question. You try and you chose the one that appeals to you the most.
Q: My battery doesn't last as long, what measures can I take to increase uptime?
A:
If you are aiming for battery life probably the most effective way to do that is by turning off WiFi, and MobileData when you are not using them (pretty logical isn't it?)
Get an app called Greenify and hibernate most of the apps that are recommended. Play services, Facebook and such are not necessary processes in the background. They will drain battery. So that will suspend them until you start the given app.
I recommend /not/ using taskers or triggers. The simple fact of having an app scanning the state of your phone, detecting the conditions and completing the task uses more battery than you doing regular maintenance yourself.
The only exception I can add here is SetCPU. Get it. And make profiles. Night mode and Screen off are a must. Just note for regular screen off don't set it lower than 300 or it might make your music stutter in case you are listening to any.
Use your battery wisely, don't waste it on games/internet if you are going to need it.
Buy an emergency charger online. I am probably going to do this soon.
Q: How do I unlock my bootloader?
A:
Follow >this guide< It's pretty detailed and has pictures and green stuff. Automatically better than anything I will be able to post here.
Note: Using a toolkit will damage your learning process. I recommend not doing it that way. You will be needing the experience later on.
Q: How do I flash a ROM?
A:
Download the desired ROM and save it to (a folder in) your SD card.
Reboot to your preferred recovery.
Make. A. Backup.
Please.
Wipe Dalvik, Cache and Data. Or factory reset, I have been sticking to the same ROM for a long time, so I kinda have forgotten. NOTE: This will delete your apps and settings.
Locate the ROM and install it. Proceed to puke some rainbows.
Make sure you have the correct kernel for the rom. You CANNOT use NOPE kernel for Sense ROMs.
Q: How do I flash a kernel?
A:
You need to have ADB. I will assume that you have it already because you have your bootloader unlocked.
Download the kernel and place it your platform-tools folder.
Reboot your phone to bootloader.
Connect it to the PC using the cable.
Open a command prompt (Hold shift and right click inside the the platform-tools folder (Not on any specific file, just inside it) and click Open command window here)
Make sure your device is recognized. (One time is enough)
Code:
fastboot devices
Erase the cache. (Optional but I do it anyway)
Code:
fastboot erase cache
Flash the kernel.
Code:
fastboot flash boot [File name].img
Where you replace [File name] with the name your kernel has. For example if your kernel is named boot800 the command will be "fastboot flash boot boot800.img"
Q: How do I flash a kernel?

Flash the recovery.
Code:
fastboot flash recovery [File name].img
Where you replace [File name] with the name your recovery has. For example if your recovery is named TeamWin the command will be "fastboot flash recovery TeamWin.img"
Copy>Pasted this part and changed some stuff. Not even sorry.
P.S. You can suggest FAQs and I will add them ASAP. It's still a WIP.
What is the best ROM?
A:
There is none. Pick the one that is right for u!
Add this to op please! :3
Also you should get this thread stickied

Yeah.. getting sticky-ed is a tough job.
On topic - you can add the procedure to change from one ROM to another "the right way" (backup, wipe, flash rom, flash kernel) in a little detail. Almost none of the problems would occur if people just follow this simple thing.
Q: my battery lasts less than when I was on stock, what can I do?
A: It depends on how much you want to invest:
1) turn off data when not in use - FREE
2) dim screen - FREE
3) use airplane mode while you sleep - FREE
4) use Greenify to hibernate non-critical apps that use wakelocks for sync and update - FREE
5) set a screen-off profile with low frequency with SetCPU - PAID (there's a free version for XDA members)
6) set a Tasker profile to activate Mobile Data at specific intervals only (i.e. every 15 mins) - PAID
I'll add more battery saving measures later

Update 1.17.4.0.1234 bugs

Anyone using the new 1.17.40.1234 update please post your impressions and more particularly any bugs encountered.
Overheating, system slowdown and poor battery life have been mentioned by a number of users on other sites.
phone is overheating whenever I am using whatsapp or simply playing games. Is there anyway to rollback to W1.16.40.763 ?

Do you have 1.17.40.1234 or 1.17.40.1106 ?
I think that they might have corrected the issues with the 1234 version.
If you want to rollback just copy the update in the phone renaming it with a upper version, for example 1.18.40.763, remember that the procedure is at your own risk.

From the asus forum try this:
1. Download the firmware to your PC
2. Rename it to MOFD_SDUPDATE, enable the view extension of the files option and check that the file has only .zip, .zip.zip is not accepted and the procedure will fail. (you should have MOFD_SDUPDATE.zip)
3. Now format the sd card in windows with default settings (fat32)
4. Copy the MOFD_SDUPDATE.zip on the newly formatted sd card
5. Shut down your phone and insert the sd card
6. To boot in recovery mode you need to:
a. Hold the power button and volume down key all together
b. When the first Asus logo appears, release the keys.
7. Go to update from sd card and located the MOFD_SDUPDATE.zip
8. Then flash
9. You can format the cache partition if you like (recommended)

Tried this method. Doesnt work. Better use cyanogen mod and TWRP
Or try this:
1.0 [Preparation of your PC]
Download the ADB Tool HERE.
Click on the setup executable and type in "Y" for all the entries. (for the prompt on driver installation, simply click "Next", "Install", followed by "Finish").
1.1
Download the ASUS Software Update HERE.
Once completed, move the update file to C:\adb (where C: is the root drive where the ADB Tool was installed at).
2.0 [Preparation of Device]
Turn off your phone.
Press the "Volume Down" button followed by the "Power" button.
Keep holding the two buttons until the recovery screen appears, then release both AT THE SAME TIME.
Plug your phone into the PC.
On your phone, press the "Volume Down" button to select the option "apply update from adb".
Then, press the "Power" button once to select.
3.0 [Flashing]
Open the command prompt (Windows Key + R, type in "CMD" and enter).
Type in cd C:\adb (take note).
Then, type in adb sideload "downloaded file name".zip
4.0 [Finish]
Upon completion, make sure that the option "reboot system now" is selected on your phone.
Then, press the "Power" button once.
Is anyone using this update that is not experiencing any problems especially battery and heating?

No issues on my ze550kl, no heating issue, no major bugs on 1.17.40.1234. But it becomes warm when I don't close any game and tap home button but that's normal.
1.17.40.1234 came with Wi-Fi and carrier network improvements. I guess people from certain region might be facing heating issue due to changes in modem. I am from India. No issues for me
I can confirm there is an issue. I just got the phone and immediately updated it the latest firmware. I am getting abysmal battery life and the phone does get quite warm at times. I charged my phone last night and when I went to bed it was at 95% battery. When I woke up the battery was at 33%. I looked at the battery logs and the flashlight app and cell standby consumed 22% each. I have no clue why the flashlight app would be using battery for no reason.

Try using the auto-start manager and making sure the flashlight app does not start automatically then reboot the phone. High standby usage can sometimes be caused by a faulty microsd card. If you have one, try unmounting and then remountiing it and see if that helps. If it doesn't try reformatting it.

How To Guide Improve Battery Life and reduce heat

Battery life on 12 Pro is probably one of the worst I have experienced. My phone is literally sucking battery life to a level I have not seen on any phone. Light usage, FB, Insta, emails, etc and Im down 40% in like 2 hours.
I did all sorts of resets, firmware updates, etc ( although latest Xiaomi EU has made it even worse in my opinion)
The solution I found, and its working amazing ( my batter life is gone from bad to super good) Same usage, same style and there is basically no drain.
The solution is to under clock the CPU. For the the phone must be rooted for the software to allow underclocking. Apk name is called 3C Cpu Manager
I basically run the CPU at around 60% of its max power. This is totally not noticeable for day to day use unless you use the phone for gaming or heavy CPU progarms.
The Snapdragon is very power hungry, all tasks are made with its using the full power which creates unecessary heat and battery drain. Its a pitty that Xiaomi doesn't have the CPU optimized better like some other phones using the same cpu with better battery life.
See images before and after battery usage and CPU settings for under locking
Hello there
I was wondering would ram management be affected after underclocking the processor? As many apps gets restarted when I do multitasking, like payment page gets refreshed when I switch app and then the payment made fails at device end.
I regret buying this super expensive brick whose ram sucks at just basic apps like chrome and gpay.
Kindly guide, as I want to improve battery life as well
It would have been more interesting to post 2 identical diagrams, ie without battery charge.
Wi-Fi is more energy intensive than data.
Is that true? Making connection to cell towers can't be more energy efficient than a close by router not can it? Especiallywhen in the move the reconnecting with and the searching for the network drains more energy I believe

Hi. What method did you use to root the phone?
I searched online but couldn't do it. I really want to increase my battery life. Yesterday I had only 4:40 hrs SoT with only social apps and web browsing.

I tried 3C Cpu Manager and saw no real improvement.
May be a little early to tell but with the latest Xiaomi EU rom A13, it displays 10 hours more at 100% which becomes 6 hours in the end.
Root:
1. Find or redownload the TGZ file for your current ROM
2. Browse inside the zip file and find boot.img under the images folder
3. Copy this file to a temporary location in your PC first, and then transfer it to your phone
4. Install the desired version of Magisk app (V23?)
5. Run the app and choose Install under Magisk
6. Choose Select and Patch a File, then select the boot.img that was transferred earlier
7. A process will run and create a new .img file in the same folder where the original one was
8. Transfer the new file to your PC in the same directory where fastboot.exe is located
9. Open a command prompt window in that same directory
10. Reboot your phone to fastboot mode and connect to PC, USB2.0 port. Check for connection by running command fastboot devices.
11. Run the command fastboot flash boot_ab magiskXXXX.img
Once it's completed, run command fastboot reboot and the phone should boot and be rooted.

Great. I will be waiting for your feedback.
Hey. This module is all you need: https://forum.xda-developers.com/t/...ife-more-than-sufficient-performance.4450435/
Try it now and you will feel the effect immediately. No more heat. No battery draining. It's perfect.
I confirm the battery life is improved with A13.

Thanks for the confirmation. I will give it a try later as my phone is rotted.

I recommend the Kirin 980 and SD778G modules.

Are you sure it works for an 8Gen1 when it seems to be more intended for the Snapdragon 888?
