I'm a truck driver and I'm a heavy user.
I did too before I made the changes below. These all work with the Stock Rom.
1. Installed No Lock (so that I don't have to swipe the screen to unlock, just push the power button)
2. Set screen to turn off in 30 seconds.
3. Installed Brightness Widget (allows changing the brightness from the home screen
4. Installed Screen Filter (lets me really darken my screen at night.
Try those and see how you do.
5. I then flashed the Infused Rom (I now get up to 10-14 hours)

Also, Turn off GPS and Wifi when you're not using them.
Battery
After much experimenting and monitoring of battery use I find that the biggest drain is the screen display, so go to settings-->display-->brightness and lower the screen brightness as low as you comfortably can. Also when you you are not using the phone make sure the screen is off, I have trained myself to automatically hit the power button every time I put down the phone. If you listen to music through your phone make sure the settings on your music players allow the phone to play when the screen is off and turn the screen off while it plays.
GPS also drains the battery, so I keep it turned off when I don't use the Nav. When I use the Nav I know the battery will drain at a rapid pace, nothing you can do there, even if I have the phone plugged in to car power while using Nav it still drains the battery! Drains slower than unplugged navigating but still drains.
If your watching videos then your S.O.L. there's really nothing you can do that will increase battery life enough to make a difference during video playback.
I get 10-12 hours with regular use and stock rom. Worst was 8 hours best was 24.
Thanks for all the advice this has really helped my battery

3. Installed Brightness Widget (allows changing the brightness from the home screen
There was a recent post that showed a shortcut for changing the screen brightness from the homescreen without any additional software. First, turn off auto brightness. Second, tap and hold the menu bar at the top. Third, slide left to reduce the screen brightness and right to increase screen brightness.

How does it drain your battery when its plugged into the car? I have never seen that on any cell phone. That my friend is messed up if true.

It seems that Samsung ****ed up and included phone CPU/screen/etc usage when measuring battery charge current.
This means that the 600 mA stock battery charge current limit isn't just going to the battery, it's split between battery/screen/CPU. If screen/CPU/etc go above 600 mA (Navigation at full brightness seems to be the most common way), battery starts draining.
It also means that unless there's something I'm missing (which I could be since the MAX8998 datasheet is super-ultra-secret), our phone isn't going to be able to do proper charge termination - if the screen is on/CPU is running, it will cause a falsely high battery charge current reading, which will cause charging to fail to terminate.
Juice defender
I found that juice defender helped my battery and i just use the free version it's a great app
I used Iphone 3g 3gs 4. None of them drain battery like this one. First time use Android phone and getting a bit disappointed of this phone. It's draining 2% every 5 mins and im using stock Rom.

look in about phone battery use to identify the biggest battery user, it should be the screen. anything else and there is a problem.
the cell standby may go high on froyo rom, turning on flight mode and turning it off will correct that, it's an android bug.
on gingerbread the android os or android system may hog battery occasionally. some think it is the wifi sleep policy but it pops up on me without setting the sleep policy. the fix for that is to pull the battery for a couple minutes and put it back in and restart the phone.
next manage the screen brightness
install a custom rom, there are issues with certain firmware keeping sensors active wen they shouldn't be.
turn off unneeded sync options (i find that auto fetching my email uses a lot especially with my gmail already set to sync),
use wifi when you use the internet if possible, turn it off when out and about.
monitor cpu useage of apps that are cached in the task manager
kill apps that use cpu
if needed turn the max cpu clock down to 800mhz
set "use wireless networks" for location when possible for general location (limited to city level at times)

Actually, high cell standby is OK if the phone is screen-off often.
Cell standby is always my top user - but my phone is sitting on my desk with the screen off frequently, in a location with weak signal. Weak signal makes cell standby usage go WAY up.
Syncwifi application is awesome for extending sync settings to gain more battery

Using titanium backup I froze drm content 2.2.1 and this significantly increased my battery life.
Sent from my Infuse. It is what it isn't.
JuiceDefender!!
I agree JuiceDefender works!! I had to charge in the middle of the day. Now with moderate use it will last all day Im on stock Rom.
I easily get 2 days out of my Infuse, no idea how some of you are managing to only get 8 hours. After rooting my phone and freezing the bloat i easily get twice the battery life of my prior iPhone 3GS.
As some of you have been complaining about your Infinity's poor battery life, I thought we should start a thread on getting more out of its battery. I invite you all to share your experiences, hopefully we could come to sth helpful together.
Perhaps when the development's carried on further by more XDA developers, we can split this to stock ROM and custom ROMs, as probably the latter will have more of these already included.
1. Arguably full charge and discharge does nothing good on modern Li-Ion batteries and it's rather advisable to keep it balanced - discharge a little, don't push it with charging all the time (however in case of the Infinity, as with many other devices, the charger will just stop consuming energy after [almost] fully charging your device). There is one reason for doing a few full discharges and charges however - so that the battery monitoring apps/widgets can learn more about your battery's life and power consumption.
2. Monitor your battery life and monitor it wisely (don't use power-consuming apps and widgets). I personally like Battery Monitor Widget, as it gives you mA and % / hour (either drain or charge), which is pretty cool, as you can see how much your usage exhausts your battery in real time. This way I've found out that switching the WiFi off while reading books actually gives me battery drain closer to 10%/h than 15%/h etc. You can see some other in this apps thread. Try different apps and see what fits you best. Don't rely on system battery usage stats, see what other apps show us and what apps and processes drain the most of your battery, show most wakelocks, etc.
3. Use as low power mode as you need (administered most easily through ASUS/Android notification bar on the bottom of your screen). There are three power modes:
power-saving (keeps your CPU at 1 GHz according to some apps, 500 MHz according to others) <- can give you up to 2 additional hours
balanced (keeps your CPU at 1,5 GHz)
normal / performance (keeps your CPU at the highest speed - in stock kernel 1,7 GHz for the 1st core and 1,6 for the others)
You have to try these for yourself. Most games run well on balanced, but may sometimes need the performance mode (keep in mind that overheating your CPU and GPU may cause the clocks to actually slow down). You may also find yourself happy with the power-saving mode, which really helps your battery to last longer, but I've noticed issues with some apps while running it (problems with pdf rendering, for example), as it probably changes more than just the CPU clock speed, but also the system behaviour. I hardly ever leave the balanced mode, mostly when curious about benchmark results
There are also different CPU governors in Android/Linux kernel, which you can change if you are rooted, but perhaps leaving the default "interactive" one on should serve you well (you can also try "conservative", but it has been argued it doesn't save your battery so well in the long run).
(if rooted) You can also use CPU management apps like SetCPU, create your custom profiles or use the default ones according to your needs (for example ).
4. In ASUS setttings switch on both power-saving options at the very bottom of the list (WiFi and dock deep sleep [the former is the same as choosing "never" in WiFi advanced settings]).
5. Keep the screen brightness as low, as you can. It's better to adjust it manually through the notifications bar or a widget than to switch auto-brightness on (some recommend LUX app, personally I had problems with it trying to outsmart me when I was doing some manual changes). I like to keep it around 30-40% indoors during the day and 0-10% at night.
6. Switch WiFi off when you don't need it, unless you need it on constantly.
For me, it sometimes also helps organise my work too, when I don't get constant notifications or when I'm not eager to browse the web all the time, when just reading something and taking notes.
7a) (if rooted) Make your device fall into really deep sleep...
Add these to your build.prop file (see the thread on tweaking):
ro.ril.disable.power.collapse=0
pm.sleep_mode=1
7b) ...and make it scan for available WiFi networks less often, for example every 180 seconds (same as above):
wifi.supplicant_scan_interval=180
8. (if rooted) Switch off all the apps you don't need that auto-start on boot with a program like System Tuner.
(f not rooted) Use auto-killer for the apps you don't need (if rooted you can do the above two together as well).
You can also deactivate unused apps (settings -> apps -> [select app] -> deactivate). Remove bloatware, too (see the first few posts).
9. Adjust your minfree values, so the low level system task killer will take care of the apps running in the background for you (see the thread on tweaking). You can try with different settings and see what's better for you. Some apps drain your battery life even when you don't use them, while others don't and it's better to leave them in the memory than run them all over again every time. Do some tests and see what's best for you, if you have time for it.
10. Switch auto-syncing apps to lower values when possible (sometimes PUSH is better, sometimes worse for your battery life).
11. Keep it simple. Too many funky animations, floating wallpapers, lots of nice widgets will make your battery drain really fast.
12. Try different custom launchers, you can set more UI behaviour rules in these (see this apps thread).
13. Use a dark wallpaper and dark themes / night reading modes (see why).
PS JuiceDefender reported to having disabled deep sleep, so stay away if possible.
Hotmail app has been said to trigger wakelocks, while overriding system wifi sleep when screen is off, so keep that in mind if you want better battery life over constant e-mail syncing.
Hit [THANKS] if it helps.
First of all, thanks to d14b0ll0s for yet another great write up. I am one of those concerned with the battery life of the Infinity. Though some review says it got up to 9-9.5 hours with BALANCED mode I believe is the mistake. By using Power save mode, I think we can potentially get to that level but still hard.
My system is NOT rooted, but I have noticed significant change in my battery life so far with following:
1. Balanced Mode to Power Save mode.
This gets me like extra 2 hours or so. WIthout this change, 5-6 hours for my usage and with this it goes up to 7-8 hours screen time.
2. Under Wi-Fi Setting change Use wifi during sleep mode (mine is in Japanese so exact wording may be different) to never. Default setting was always. Prior to this change, I lost quite bit overnight unplugged; however, after the change it loses negligible amount.
Now rather than these, I am trying to play around with Juice Defender, which was recommended by d14b0ll0s in best application list he created. I have initially downloaded Juice Defender Free edition, and noticed may be minimal gain over #1 already instituted. But concept was great. So I ended up purchasing Ultimate edition, which allows us to control when to turn of WIFI per individual application based without Root i.e. while reading PDF I don't think I need WIFI connection.
https://play.google.com/store/search?q=juice+defender&c=apps.
I am still tweaking and playing with Juice Defender, but I am certain without change in #1,#2 (which are actually taken care by Juice Defender in its own way), I can gain same battery life and my hope/guess is I can get even more battery life.
So in conclusion, for those not rooted try Juice Defender (at least free version). I will let you all know how the ultimate version does in next couple days.
Thanks for this! ^^ Post 1 updated.
Have you noticed what power-saving mode changes apart from CPU (& GPU?) clock speed? Does it change auto-sync settings or unload some modules? I'm not using it, as it is too slow for me to render big pdfs consisting of scanned jpgs. But when I'm reading them with WiFi off on balanced, I normally get 9.9% drain per hour according to Battery Monitor Widget, which even with some other things that I do from time to time and some additional rendering when opening new files should give me about 9 hours on a single charge. Browsing over WiFi gives me about 7.
The Wi-Fi settings you mentioned are the same as WiFi power-saving settings on the bottom of ASUS setting list, but I've clarified that in post 1 now.
I'm happy JuiceDefender helped you, it's good to advertise it here. I'm adding the info about your post apart from the link to the list of apps.
Thanks
I would also add that it's good the deactivate unused apps/widgets (settings -> apps -> "select app" -> deactivate)
it's only possible for apps which cannot be uninstalled
Good point! ^ Added (-> p. 8).
Mine will be here this weekend.
Thanks d14b0ll0s
Look very useful! I'm about to try.
I think the standby time is awesome. Wifi off, power save mode enabled and left the tablet over night right after full charged battery w/o dock. After 10h still 100%.

#nice
The system measuring system isn't exact, and early on so are all the indicators, so don't rely on it too heavily. There may be a variance of 1-3% and a lot more in the usage indicators. Try different battery / apps widgets and compare the results.
Anyway, deep sleep is nice indeed. It normally drains about 0.2% (-0,5%) per hour, mine is now 98% after the night off the charger and responding to a few e-mails in bed
Thanks for the info, it's appreciated.
Antutu's Battery Saver worked great on my 101, I'm observing how it will regulate the power drain on my 700. Hopefully it will keep the back of the tab cool as well.
i think the problem is when you have wifi on!

this is good when you have wifi off. however, when you have the wifi on, it shows 80% wifi and 20% screen consumed by battery. you can stop network access by disabling wifi from Asus customized settings and also in wifi setting, you can keep wifi on during sleep to NEVER. this helps a lot..
Stock battery (usage) stats are not relevant, use other battery apps or widgets for that.
I've heard good things about AnTuTu's bat.sav., but also that it doesn't let you have more insight into what it's actually doing, so JuiceDefender seems a better option in that matter.
d14b0ll0s:
Do you know the specific voltage setting / configurations coming out of the usb line?
Is it 16V and how does it distinguish between 16V and 5V on the single USB cable.
For example does the voltage cable go on different lines for 16V and 5V for the TF700?
Or is it 16/5V dual switchable on the same power cable?
I'm asking this is because there's interest to charge the tablet by using alternative methods such as mobile battery with 16V setting.
If so, then does a DC to USB cable be suffice for the job? Or is the cable wired differently as proprietary ASUS?
Thanks!
Sorry, I wouldn't know that. There some ppl here that are doing some testing with the batteries and hardware, perhaps the_kreature or MartyHulskemper could know something. You should post it as a thread in Q&A too.

First of all, the charger gives 15V, not 16V. Avoid giving your tablet too much voltage as that can kill it...
Secondly, the included cable is a USB 3.0 cable and therefore has 5 extra pins (you can see them if you look straight into the USB plug). These extra pins are used to get 15V from the charger. I don't know exactly how that works, but I guess the tablet tells the charger it wants 15V over the power lines (same power lines as 5V) rather than the charger giving 15V over these extra pins (because that could be devastating to other USB 3.0 gadgets). This is why the tablet won't charge if you insert an old (USB 1.0 or 2.0) extension cable between the charger and the tablet.
Hey I'm running with wifi on during sleep and I seem to get great battery performance (2% loss over 11 hr standby). No build.pro tweaks so no deep asleep our anything like that. I'm wondering if anyone else has gotten similar performance?
I thought it was interesting because the results were the opposite on my tf300t, and my usage pattern hasn't changed much between the two devices.

Same here. Battery life on deep sleep with WLAN is great!
But I think the Infinity needs a lot of power while reading news, tapatalk, Reader HD..
Not more than 4 hours Screen On Time!
And that with balanced mode and 50% brightness.
Any problems with the fifth companion core?
PS: Is there an app which shows the activity of the different cores?

"90%" Does not mean it drains 90% of your battery.
It means 90% of the current battery drainage belongs to that process. So 90% of the 15% battery drain comes from Cell Standby, the remaining 10% are other processes (usually Screen.). So something else is draining your processes.
Cell Standby is the same as Idle Processes on Windows: Nothing.
It should use about 1-3% per night even without 3rd party airplane mode. So, based on not using that, which of these do you have enabled:
WiFi (Especially the "Keep during sleep" setting. Even with WiFi toggled off, this keeps running undetected. Same goes for USB Ethernet.))"
GPS
Power saving, Balanced or Performance mode?
Power Saving in settings
Auto brightness
Location services (settings --> location services), any of the settings in this menu.
Ever used a USB Ethernet adapter?
Using any overlay apps? (handwriting, graphic effects, alarm etc?)
Does the tablet's location get very cold overnight? Lithium-Ion batteries hate the cold, drains them 10 times as fast.

Idle is called "Tablet idle" on my TF700. "Cell Standby" sounds like the connection to a mobile network, which should not even run on a wifi-only device.

This was my first idea as well -- your 700 doesn't even have a cell connection, so this is a strange entry. Try using BetterBatteryStats or something alike, because the standard Android report of battery consumption is notoriously vague, and most of the times downright incorrect.
This harkens back to my SGS2 tweaking days in which loads of users were clamoring for tweaks to get the Android System consumption down from 99% -- "it is killing my battery" -- even when they had less than 2% overall consumption overnight. LOLOLOL!
These are high-powered devices, people -- if you'd want two weeks of standby time, you should have hunted down an old Nokia Communicator.
I still find a 15% drop in 9h of stand by time a bit high. Mine is a lot less than that...

Hm. Regarding the USB Ethernet adapter: Did you ever set the option "Keep during sleep"?
Reason I ask is because the moment I turned this on, it started draining my tablet+dock in a day, even without the adapter. Turned keep during sleep off and it went back to 1% a day. Never showed up in any battery monitor.
jcp2, do you have the TF700KL model version??
I will plug the usb ethernet adapter back in when I get home and see if the option "keep during sleep" is checked.(I only used the usb adapter twice.) I have the TF700T model.
Update.... I docked the tablet and plugged in the usb ethernet adapter. "keep ethernet awake during sleep" was checked. I unchecked it. I will let it sleep overnight and check the battery usage in the morning.

Fingers crossed, then.
Great news everyone! After following ShadowLea's advice about the unticking the USB Ethernet option for "Keep during sleep" (Which is only visible if you have the USB Ethernet adapter plugged in BTW) I am very happy to report that my tablet lost only 2-3% over a 9 hour period overnight. :victory: Thank you very much everyone, especially ShadowLea for the heads up! :highfive: :good:

Same problem here, except even more extreme. My battery dropped from ~90% Tab + ~30% Dock to 24% Tab and a dead dock overnight. The culprit for me also appears to be cell standby at 90% of usage.
I do not have the KL model and so there is no cell radio, and have never used a USB to Ethernet adapter (didn't know that I could, I might try it out now that I know).

I'll try turning off the Location & Google Search, but anyone have other ideas?
EDIT: See screenshot http://db.tt/ph1d0FVT
I keep Airplane mode checked
GPS off
location settings all unchecked
under ASUS customized settings: check "mobile dock battery saving mode" and also check " disconnect network during sleep" , Uncheck "enable smart backlightlighter adjustment"
These settings cured my battery drain problem. Good Luck!
There is a known bug with Location Services that causes battery drain, as it keeps checking for a signal, even with WiFi and the app off. Turn it off
Hey guys so I know there are a few things that can improve battery life and some things that are supposed to help but may be a mith? Things as only draining battery to 10% and charging to 90% or something like this. What are tips that help? Also if you guys have changed your cpu settings that really improved the battery life let us know!
I drained my battery down to 0% after the second time I used it and it pushed my battery up from 3:30 to 5:30. I also use batterybar to see the stats and whatnot. Another thing you can do is go into power options in the Control Panel and change the plan settings > advance power settings. I usually change the Processor power management settings and the Intel Graphics Settings.

do you ever charge it to 100%
Does leaving it on the charger like when playing a game or something matter? Does it stop charging once it reaches 100
AFAIK, leaving it on the charger shouldn't matter. It's a smart charger. I always charge it to 100%, but never go lower than 10%. I try to recharge around 15%.
Best thing I've done is disable my bluetooth since I have no devices that use it.
Second is lower the brightness while on battery.
I'm getting around 5:30 of battery life doing things like browsing, email, news reading, and using Autodesk Sketchbook Design.
Disable automatic brightness. Change the screen timeout to the lowest value that works for you. Turn off BT. Turn off live tiles and notifications for apps you don't need to update on your main screen and lock screen. Run the troubleshooter for power and see if you can deal with what it changes.
While I've had many Android phones, this is the first phone that I decided to use a battery charging controller to regulate how my battery is charged. I just wanted to share my journey with others and encourage others to try this out if you are not already.
Although there are several different battery charging controllers out there (and more than one named "ACC" which makes it even more confusing) I decided to use the Advanced Charging Controller module developed by VR25. I choose this module because I felt it provided the most customization.
Step 1 - Installation
Installing the module is easy. It is listed in the Magisk repository. Simply browse the available modules and find the one titled, "Advanced Charging Controller (acc) created by VR25 @ XDA-developers". There are several ACC modules, so make sure you install the one by VR25 to follow this thread.
Magisk will flash the module and start it automatically. You don't even need to reboot, although it is the only way to clear the Magisk notification that the module will be started at the next reboot.
Step 2 - Changing the Charging Switch Setting
I found that the default charging switch setting (auto) does not work reliably with our phones. Therefore I would suggest changing it using the commands below. Personally I have choose option 2 (battery/charge_disable 0 1) but I listed all the options with the quirks that I have found with each one.
Step 2.1 - open your preferred command line app - I use Terminal Emulator.
Step 2.2 - type "su" and hit enter to gain root
Step 2.3 - type "acc -s s" and hit enter - this is the command that allows us to select another charging switch
Step 2.4 - type what number of the charging switch you want to use.
Here are the available charging switches and the issues I have found with them:
1) Automatic - this switch tries to cycle through the available switches until if find one that "works".
- Passes the ACC switch test (type "acc -t"): Yes
- Charges and discharges according to the cooldownratio: No - I found that the phone would charge anytime it was plugged in and below the Pause threshold. It did not seem to wait until the battery level was below the Resume threshold.
- Works with battery idle mode (the phone will pull power from the AC power and not the battery when the battery reaches the Pause threshold): Yes
- Begins charging when phone reaches Resume threshold: Yes
- Charging "chime" and battery icons correctly reflect if the phone is charging or discharging: ???
- Suffers from wakelock issues when phone is plugged in but not charging: It does have a "overheat_mitigation" wakelock when on the battery idle mode, but because the phone is not using the battery power, it doesn't effect battery life and therefore I don't concern myself with this issue.
- Other issues:
2) battery/charge_disable 0 1 :
- Passes the ACC switch test (type "acc -t"): Yes
- Charges and discharges according to the cooldownratio: Yes
- Works with battery idle mode (the phone will pull power from the AC power and not the battery when the battery reaches the Pause threshold): Yes
- Begins charging when phone reaches Resume threshold: Yes
- Charging "chime" and battery icons correctly reflect if the phone is charging or discharging: ???
- Suffers from wakelock issues when phone is plugged in but not charging: It does have a "overheat_mitigation" wakelock when on the battery idle mode, but because the phone is not using the battery power, it doesn't effect battery life and therefore I don't concern myself with this issue.
- Other issues:3) battery/input_suspend 0 1:
- Passes the ACC switch test (type "acc -t"): Yes
- Charges and discharges according to the cooldownratio: Yes
- Works with battery idle mode (the phone will pull power from the AC power and not the battery when the battery reaches the Pause threshold): No - phone begins discharging from battery when Pause threshold is reached but the phone is still plugged in
- Begins charging when phone reaches Resume threshold: Yes
- Charging "chime" and battery icons correctly reflect if the phone is charging or discharging: No - may show charging icon when phone is really discharging, especially during cooldownratio times and the chime doesn't always ring when charging resumes.
- Suffers from wakelock issues when phone is plugged in but not charging: No
- Other issues: The phone seems to follow the cooldown charge/discharge times even before reaching the cooldown threshold. I find the phone pausing for 10 seconds (my cool down ratio) when the batter level might be a 50% - long before the 60% cooldown threshold I have set in the config file.4) dc/input_suspend 0 1:
- Passes the ACC switch test (type "acc -t"): NO, so this switch doesn't work with ACC
- Charges and discharges according to the cooldownratio:
- Starts discharging when the phone reaches the Pause threshold:
- Begins charging when phone reaches Resume threshold:
- Charging "chime" and battery icons correctly reflect if the phone is charging or discharging:
- Suffers from wakelock issues when phone is plugged in but not charging:
- Other issues:5) battery/charge_control_limit 0 1:
- Passes the ACC switch test (type "acc -t"): NO, so this switch doesn't work with ACC
- Charges and discharges according to the cooldownratio:
- Starts discharging when the phone reaches the Pause threshold:
- Begins charging when phone reaches Resume threshold:
- Charging "chime" and battery icons correctly reflect if the phone is charging or discharging:
- Suffers from wakelock issues when phone is plugged in but not charging:
- Other issues:
Step 3 - Configuration
You can configure the ACC controller using a couple of different methods. You can do everything using command lines, you can use the beta ACC app (see note below), or you can edit a config file that ACC creates when it is installed. Personally I found that editing the config file was the quickest and easiest method to make general changes.
The ACC config file is found at /storage/emulated/0/acc The file is named "config.txt" You can open the file with a text editor. I personally use the app Root Explorer. I long click on the file name, and then press the three dot button in the upper right hand corner. Choose "Open in Text Editor" and the config file will open and allow changes to be made. Saving the file will automatically push the changes to ACC, you do not need to reboot or restart the ACC daemon for changes to take effect.
I won't go into a lot of detail about all of the different configuration options here as the developer's xda thread is the best place to get that type of information. But I will talk about the most basic setting - the "capacity" setting. It is the second setting listed in the config file and it should look something like "capacity=0, 60, 70-80". Here is a break down of what those numbers mean:
- The First Number (0): is battery level were the phone will shut off. The default setting of 0 means the phone will turn off when the battery level hits 0. Personally I don't want my battery completely draining, so I have it set at 5.
- The Second Number (60): is the battery level where the module starts it's "cool down" functionality. Cool down (listed as coolDownRatio in the config file) is where the phone will stop charging briefly and then restart charging. The default "cool down" setting is coolDownRatio=50/10 which means the phone will charge for 50 seconds, and then stop charging for 10 seconds before charging again for 50 seconds, etc, etc, etc. This is designed to keep the battery temps low. A battery with a charge level less than this number (60 in this example) will charge without pausing, but when the battery level gets to this number or above, the phone will charge and pause based on the coolDownRatio.
- The Third Number (70): is the "resume" value. If the phone's battery level is below this resume value, the phone will charge. If the battery level is at or above this resume value, the phone will not charge even while plugged in.
- The Fourth Number (80): is the "pause" value. This is the battery level where the phone will stop charging and should not charge above this value.
The default settings are set this way because research has shown that a phone's battery will last the longest with the least amount of battery capacity loss if it is charged to a max of 80% of the battery's capacity, and allowed to discharge just a small amount (10%) before being charged again. I realize this goes against the old "wives tale" that our phone's batteries have a very limited number of charges and it is best to limit the number of charges by only charging the phone when it gets to a low level. This is not true in actual battery performance however and if you charge like this, you are actually decreasing your battery's life expectancy and performance.
Obviously the default settings may not be the best setting for you. The default settings are probably only practical for a device that is plugged in 100% of the time. Personally I have changed my capacity setting to capacity=5, 60, 70-90. This means my phone will turn off when the battery level reaches 5% (something it has never dropped to yet), it is charged to a max of 90% and will discharge to 70% before charging again, and the cooldown charging cycling starts when the battery is 60% or higher. Obviously I'm not on my charger all the time, so it is very common for my battery to drop below 70%. However, if the battery is below 70% and I have a charger at my disposal, I am going to charge the phone back to 90% rather than let it the battery levels continue to fall.
Final Notes and Misc Thoughts
There are lots of other options and commands you can use in ACC. Feel free to share any changes you like to make, or post if you are having problems getting the module to work as expected on the 3a. I hope this helps some people feel give the module a try.
There is an ACC app that is available now that allows you to control some of the settings from a nice GUI. I personally did not like using it as I found it would overwrite settings in the config file that I was not intending to be changed.
There is an ACC telegram group if you want to join and have direct communication with the developer and others.
Thanks to @jellopuddingstick for educating me on what the battery idle mode does and why it is beneficial to have it working!

Was doing the same research when this popped up -- great job!
Can you discuss more on what unintended settings were overwritten by the app....
Also, thoughts have seem to have standardized now to lop off 40% of usuable capacity by having the battery charge btw 20-80% to extend life, such as... "capacity=20, 60, 70-80".
How were the defaults for ACC set and why have you chosen otherwise?

The app works by writing to the normal config file. But it also has three profiles loaded into memory automatically when you install it. This makes it very easy to press on one of the other profiles by accident and totally change your settings. I eventually deleted all the "extra" profiles, but the charging switch isn't changeable via the app either (it seems like it defaults to auto) so the app will overwrite that setting back to auto if you aren't paying attention.
In the long run I found that using the config file was extremely easy and I found myself having the check the config file anytime I used the app to make sure it wasn't changing unintended settings, so I decided to remove the app and just use the config file.
As far as capacity, I decided to run 5, 60, 70-90. I think it is a good compromise between having a decent amount of capacity available and also not charging the phone to 100% all the time. I could probably get away with a limit of 80 or 85, but ultimately decided on 90. I do try to charge my phone when it hits 70 or below if I have a charger available vs waiting to do a larger/longer single charge.

Don't you think 70 is too high to begin charging just to bring it back to 90. Doesn't number of charge cycles kill battery life as much as heat and fast rate charging?
Any good apps you like that intuitively monitor battery health, besides just stats and charts, that does it like apple, as a percent of remaining chargeable capacity?
Btw OT question, looking to move over my wifi connections from the previous phone and can't find the wpa_supplicant.conf file in /data/misc/wifi in the 3a. No reference online mentions that it's been moved. Any idea where they're hiding it now? Thx...

According to this research (https://batteryuniversity.com/index.php/learn/article/how_to_prolong_lithium_based_batteries/), the more your battery discharges, the fewer discharge cycles it will survive before really negatively effecting battery performance. So discharging your phone just 10% might give you 6000 discharge cycles, while discharging your phone 60% might reduce these discharge cycles by 90%.
Obviously I have to rely on other people's research as there is no way I can adequately test this myself. But I do trust this research as accurate. I know with other phones I've had where I did not try to control the charging system I have had to replace the batteries with pretty regular occurrence. But I would leave the phone on the charger overnight (not a good thing for battery life) and try to discharge the battery a lot before charging it back again (also not a good thing for battery life). That's why I decided to finally look into using a charging controller like ACC with this new phone.

I've been using the ExperimentalX helper app to track battery usage. (You don't need to use their kernel to use the helper app). I like it because it breaks the battery usage stats into two parts: when the screen is on, and when the screen is off, but it doesn't attempt to give a percent of remaining chargeable capacity. I'm not aware of an app that does that (although I too would be interested to know if such and app exists).

I think the info you are looking for is now stored at /data/misc/wifi/WifiConfigStore.xml.
As I use my phone more, I realize that none of the charging switches seem to work 100% of the time as expected. I'll continue to do trial and error tests, but please share if you find a switch that works consistently.
I've continued to edit my original post to provide as much information about the different charging switches and the issues I see with each one. Hopefully it is easy to understand.
I still find myself defaulting to the 3rd charging switch option and while it can act a little erratic sometimes, it does work normally most of the time.
Is it possible to disable/bypass the cool down period?

The default setting is for it to be turned off I believe. Look in the config file for "coolDownRatio=" and see if it is blank. If it is not, you can remove everything after the equal sign.
Another way to do it is set the cooldown threshold number to be equal or higher than your "pause" threshold. So you might set this as "capacity=5, 100, 70-90". The 100 represents the value at which the cooldown process would start, which is higher than the pause threshold (at 90 in this example) and therefore would never kick in.
All this being said, I find that the #3 switch option seems to allow the cooldown pause/charge process to start below the set cooldown threshold. I have my cooldown threshold set at 60, yet find the phone pausing and charging at battery levels below this threshold. This should not be happening, but is something I can live with, so I haven't bothered to follow up with it.
After several more weeks of use, I've updated the initial post again. I found some quirks with the "automatic" charging switch, so I have gone back to selecting charging switch option 2 (battery/charge_disable 0 1).
Great job!
May I ask you whick kernel you are using for "battery idle mode" support? It should not be supported on stock kernel.
Thanks
