I remember seeing an App which tells you how much current/voltage you are getting from your charger. It was a very simple app, once you click on it it gives you your charging source's voltage/current reading. I tried searching a lot but cant find it, every time I search only battery readers comes up which I dont want. I want to get the current/voltage reading of the plugged charger.
I am absolutely sure there is an app like that, can someone point me to it?
I've yet to see an app that can do this.
I was looking for this a long time ago and found this way to do it via GScript:

Hope that helps
The 'BatteryLife' widget (by curvefish) shows the following:
Charging-A/C or USB (slow/fast)
Temp
Voltage
percentage
health?
battery type/technology
If you want to see the current being drawn from the battery try 'CurrentWidget'
Has anyone find something to see the charging voltage?

though not nearly perfect but works on few devices
Ampre in the app store. All devices. Tell input amp from charger. Just be sure to take into account your phones operating Amps. So if the app says your chargers putting out 700mah then add about 300mah for your phones e screen and all that and you have about 1000mah output from the charger once you turn your screen off and screen is locked.
Now looking for one that also shows voltage (qualcom quick charger that only puts out 6.2V and 2.2A according to a USB-power-monitor, but I want to make sure the monitor is NOT to blame before yelling at the seller of the quick-charger, my other quick-charger has disappeared since a trip (iirc that DID show 9V and 1.5A with same USB-power-monitor and same phone (Redmi Note 7) and the Samsung Quick-chargers that came with the wife's A40 won't quickcharge my Xiaomi).
I remember getting a Windows phone from work in 2008 or so. One of the first apps I downloaded (and one of the very few available for Windows...) was a charging-current app. We used it to quick-test micro-USB-cables at work

Check BatteryGuru, I am the dev of it.
It always says charging voltage is 5 volts.... I'm charging at 9v, uninstalling app
This is for kernel devs only. The patch itself is useless to those who do not/can not compile their own kernel.
This was a pretty big hit on some other devices so I figured I'd give it a shot for you gys. This allows one to force AC charging for any charger that is detected as USB (e.g. many car chargers) and pull the full current the charger can support. It also provides additional security when connecting to public charging stations because by forcing AC charging, USB/adb data transfers are disabled, protecting your data.
It is essentially a software version of the modified charge only usb cables.
Fast charge can be toggled by issuing:
echo 1 > /sys/kernel/fast_charge/force_fast_charge
and off:
echo 0 > /sys/kernel/fast_charge/force_fast_charge
In addition I have created a toggle fast charge widget that may be used to toggle fast charge on and off right from your home screen:
https://play.google.com/store/apps/details?id=com.incredicontrol.fastchargewidget
I have also implemented a toggle in IncrediControl (free) that will allow you to turn it on and off.
https://play.google.com/store/apps/details?id=com.incredicontrol
For the widget (or any fast charge toggle) to work, you MUST be running a kernel that has this patch implemented.
As a good gesture to support a fellow dev, I ask that if you implement the patch into your kernel, please link to my widget as one means to toggle it. You are of course free to provide other ways to toggle it as well if you so desire.
Kernel devs, if you would like to test the widget yourself to confirm its working, and for convenience of testing, please contact me and I will provide you with a copy. You must show that you are a kernel dev though (i.e. link me to your kernel post so I can match your username).
Good luck have fun!

I'm willing to give this a shot, quick question though, does this use AC charging if you plug it into your computer? Or is it only for other sources, such as the car charging you suggested?
Will dual mount SD, or multi mount still work after enabling this

When on, it will be detected as AC for any source normally detected as USB. This includes your computer. Not every computer can put out enough amperage to significantly increase charge speed though. So it depends on your charging source. Even if your charging source can't put out more than 500mA (what USB charging is limited to), since the phone is in AC mode, it will be able to sleep while connected to the USB source so you will see some small gain because of less power usage from the phone.

When you have the feature toggled on, the phone is in AC mode and all USB transfers are disabled. Turning it on and off is as simple as tapping the widget or opening an app and unchecking a box though.
Tap the widget on (or other means of toggling) - AC mode
Tap the widget off - Auto (detects based on charging source like stock)

Fast charge? I remember having that on the DHD, Lord Clockan's work. It was great having that extra overcharge + fast charge...
I'm no dev, but having this feature on future ROMs would be very nice.
-----
Any chance you can max the current input? I mean... it begins at >+900mA when the battery is very low, and the current slows down as the battery charges.
Also, when playing a game that, say, consumes about -400mA and the current input is +800mA, the current will slow down to +400mA only (since another 400mA are being consumed by the phone). You can immagine what happens when the battery is almost full and you're playing a game...
I am guessing that having the current input always maxxed out would charge the battery (a lot) faster. Would that damage it, too? If not, could it be implemented?
in experience, below 80% the numbers are as per below
900+ ma WALL PLUG
400+ ma USB
600+ ma CAR CHARGER
these are rough numbers, not accurate
after 80%, they tend to be slower

I can't press "Install" while Filter Screen / Screen Adjuster is running / turned on. That's the only thing that prevented me from installing apps until now... If you have that installed, I suggest you turn it off for the time you're installing apps.
Otherwise... I don't know... Wipe cache, dalvik, fix permissions, zipalign apks...
Id love to see this implemented.. im running the standard LeeDroId kernel.. id happily flash it over the top if that would be of any help. I do 80% of my phone charging via USB.

I would be concerned with heat buildup and possible damage by pushing that much additional current. Not to say its not possible, but I would be leery of implementing it.

As I thought. Not going to make a fuss about it, it was just an idea; I knew it could be dangerous
I bought a pack that had a car charger and a wall charger (both of supposedly 1A output) - lighter than the battery cap of the EVO 3D, rofl. The car charger worked perfectly (the power output was meeting the expectances). The wall charger barely sends 30mA (ROFL). In the pack, I also got some sort of expandable Apple cable. The entire "pack" was cheap Chinese crap, I paid ~$3 on it.
I still have the oh-so-good wall charger. It didn't push much current to the Desire HD even with the fast charging kernel...
Guess in cases like that, there's nothing any kernel patch would be able to solve, eh?

I just installed that newer version of BMW. Selected HTC Evo (test) as mA retrieval method. Battery is at 90% and the input current is +305mA. Also, I disagree that the phone takes +900mA from the wall charger when the battery is under 80%. Input over 900 is only when the battery is like under 10%... At 50%, for example, it isn't +900...
ive got 3 wall chargers, and all of them are original from the phones I bought respectively, HD2 HD2 and EVO3D
they report about 900 below a certain %, and it could be 40% , 50%, 80%, etc
i guess you get the drift
anyways, you are supposed to select Automatic to get proper drain readings
forgot 2 mention that
Still need a tester to PM me. Have a test kernel ready to go, just need confirmation so I can post the patch.

As the title says...what's the strongest charger? I've noticed my current one when using the GPS with navigation even with it plugged in it'll still lose battery life. Current model I have does 750mA. Are there better ones out there?

There are ones made for tablets that outputs 2.1A. Not sure how much our phones can actually draw from it though.
EDIT// Per Entropy
Entropy512 said:
Basically, anything with a rating of 0.7 amps or above which shorts D+ and D- together (indicating a dumb charger) will behave the same.
Our internal charging chip limits to 650 mA on AC and 400 on USB. So the only thing you have to watch out for with cheap chargers are:
1) Voltage WAY off from 5 volts (USB standard) at 650 mA load
2) Does not properly signal "dumb charger" causing the phone to charge at 400 mA

right my problem is finding one that not only draws 1000mA and uses it. I have one that when I plug it in it'll say AC charging and on the unit it says 1000mA but it obviously isn't doing it's job if I'm losing battery life while running GPS navigation in the car. Short of me buying a bulking inverter for the car so I can plug a wall outlet plug directly into it I'd prefer to find a USB to 12V that works right.
I briefly thumbed this thread to get a bit more educated but still no luck on finding a product that works...

I have the AT$T-branded car charger and when I was using the phone for nav I had no issues with over drain unless I also was streaming Slacker or Pandora at the same time. I now have a truck with built-in nav, so I no longer use the phone for that.
my concern is because I just got a Passport 9500ix and I'm using the live cord so it requires the screen to be on, bluetooth on (which is on anyways for my handsfree), and a GPS signal to be on.
I normally don't use GPS either in the car as I have a built in nav for my vehicle.
I use mine with BT in the car and streaming Slacker with the screen on constant and I never turn off GPS. Have yet to have a charging deficit issue with the aforementioned charger.
well the LiveCable had a USB port on it, plugged it in, and says Charging (AC).
Let's see how this thing holds up I'll re-post in this thread if there's a problem. I'll try it's port instead of my current socket which is not sufficient.
Per another recommendation by Entropy I use SetCPU to limit the cpu to 800 MHz when the navigation app is active. There's still enough power left at this state to allow the phone to build a slight charge if plugged in, or to limit battery drain if it's not.
The simple reality of the situation though is that nav consumes a ton of battery. Running the screen, rendering the maps, running the gps, downloading the maps over cell data etc. all at once consumes a lot of power on any device.
In situations where the battery is getting very low but I still need to use the navigation app I also sometimes just turn off the screen and rely on the audio directions. This helps limit power drain quite a bit.
I wonder how much current he official Samsung car dock supplies?

interesting about setting CPU down when running navigation! I'll have to try that.
Well the good news is with a combination of the stock USB cable plugged into the Live cord for the radar I'm actually charging now while using navigation (slowly but it's charging). Full brightness though it'll either hold steady or drop maybe 1% in 45min or so. Anything but high brightness and it'll charge.

Samsung car dock just uses whatever its input is. The phone treats it the same as an AC power supply - 650 mA limit regardless of what the power supply capability is.
Interesting note: The power supply's method for signaling a "dumb charger" becomes irrelevant on official docks. All the phone knows is it's docked and it has power, it assumes an AC charger. As a result, power supplies that are intended for iDevices will get detected as USB (400 mA limit on I777) if connected directly, but AC if connected via dock.

Recent versions of SetCPU make it really easy to set a profile that triggers automatically when the nav app is started. Well worth the $1.99 price of the app.

So I've been using an app called Battery Charge Limit from the Play Store (https://play.google.com/store/apps/details?id=com.slash.batterychargelimit) to limit my battery charging upto 80% using root access. This was to increase the longevity of the battery.
Worked fine on Oreo, but now for some reason it doesn't seem to stop the battery charging at 80% on Pie. I was wondering if anyone else has encountered this issue and has found a fix/workaround?
I know its probably better just to ask the app developers, but I was just wondering if anyone else is having this issue as I also have access to an S7 Edge on OneUI Pie and it doesn't seem to have any issues.

I do not see any sense in such charging settings, the V30 with 100% notification is still charging for 30 minutes with low current and then only reaches a physical 100% battery which is to save the battery. As the program disconnects charging at 80% it will be physical about 70% = 2/3 for battery use. You probably don't discharge the battery less than 30% because you will "damage it". Then use 1/3 charging it 3 times at the same time as I do ... So think about whether after these 4 years you won't have a more dead battery than I, kids, I charge 15> 100%.
Yes, the answer is simple, charge up to 100% and disconnect immediately, just like LG limits charging to physical 95% so that the battery does not lose capacity.

Fair enough. I simply limit it to 80% as from what I understand the majority of battery wear happens between 80-100%, even if it is charging at a much lower voltage and current.
Even if the phone doesn't show the true values of physical charge, a physical 70% charge is enough to get me through the day and I don't worry too much about how much battery I drain so only put the phone back to charge when it's at ~5%. So only charge the phone once a day.
Even if it may/may not make a difference to longevity it's worth a shot. At best it'll improve the lifespan of the battery, at worst it'll do nothing with normal degradation.
Maybe in a year or so when 80% charge can't get me through the day I might drop the limit. For now it seems worth a try.

Just for your information, deep discharges are also not very good for Lion batteries. Discharging to 5% regularly is as bad, if not worse, than charging to 100%. The optimal is to always keep the battery level between 40%-80%.
I am not so sure if that will make any visible real world difference since most people don't tend to keep their phones for too long. And since that limits the effective battery capacity too much, I would suggest that you don't worry too much about charging/discharging too much.

To answer your original question, the same feature works as intended on a different app (AccuBattery) on my phone, stock unrooted open EU H93030b. So it looks like your problem is not the OS but the app.

Just for your information, deep discharges are also not very good for Lion batteries. Discharging to 5% regularly is as bad, if not worse, than charging to 100%. The optimal is to always keep the battery level between 40%-80%.
I am not so sure if that will make any visible real world difference since most people don't tend to keep their phones for too long. And since that limits the effective battery capacity too much, I would suggest that you don't worry too much about charging/discharging too much.

Yeah I am aware that discharging to 5% can be just as bad for the battery. But even if I charged to 100% I would still use the phone till there was only 5% left. So I just thought might as well try to limit the charging and see if it makes a difference on the long run, since 80% gets me through a the day anyway.

Thanks for your help! I did try out Accubattery and yes it detects when the battery is at 80%. Just wish it could set limits with root access as well.
In any case, I seem to have found a solution now. There's a Magisk module called Advanced Charging Control (ACC). This seems to work well and limits charging to 80%. It also has a companion app that you can use to set your own preferences and limits.
I've linked the relevant thread below, might be useful to others.

Your doing more worse then good letting the phone go to 5%. That app will not do ANYTHING for you.
Sent from my LG-H932 using XDA Labs
I find ACC works well at stopping the chargeing at a certain % level.
Hoiwever then while still connected to usb it draws power from the battery - not good.
Battery charge Limit on Oreo stoped charging and used then power from usbb onwards while still connected.
I wonder how ACC stops the charging on Pie, i.e. with what control file. Has anyone got an idea?
I foudn out that the switch is /sys/devices/platform/lge-unified-nodes/charging_enabled. This starts/stops the chargi8ng.
Unfortunately, on Pie, when this is set to disabled from then on power ist not drawn from the charger but from the battery.
Is there any other switch / wax to prevent this?
Ich want charging to be stopped and from then on power to be taken from the charger while connected to it.
Here are the paths to the CTRL files that I've found to work with the two ROMs that I've used recently:
Havoc-OS wired and wireless: /sys/devices/platform/lge-unified-nodes/charging_enable (no 'd' on the end, unlike what bladecgn gave)
Lineage OS wired: /sys/class/power_supply/battery/charging_enabled
Lineage OS wireless: /sys/class/power_supply/dc-wireless/charging_enabled
One quirk that I've noticed is that, on wireless, the app ignores the "Recharge below" setting and starts recharging as soon as the percentage drops just 1% below the max (ex. if the max is 80% and the charge drops to 79%, it'll immediately recharge back to 80%, even if "Recharge below" is set at 76%).
For the record, the ROM that I'm using is LineageOS 17.1, so the app definitely still works on Android 10.

Were you able to figure out how to use only power from the charger instead of the battery, @bladecgn?

Stock Pie doesn't have the /sys/class/power_supply/battery/charging_enabled file, but it does have /sys/class/power_supply/battery/battery_charging_enabled. Would that work?

I don't know. You'll just have to try. It's a process of trial and error to find which path works with which ROMs.
Hi,
Do you know if it is possible to limit the maximum charge level, like it's possible on Samsung devices? If it's not out of the box, is it possible to achieve that on a rooted device?
It's quite useful feature to preserve your battery life.
Thanks a lot!
All I found in the stock OS is "Optimized Charging" and "Overcharge protection".
First one learns the patter of your charging, pauses at 80% and continues to the 100% some minutes before you usually unplug.
2nd one, quote: limits charging when your device has been plugged in continuously for 3 days.
I dont feel like I need either, the phones charges to 0-100% in ~30 minutes with the charger it came with and the battery lasts for 1.5-2 days with moderate use and turning off services you dont need like bluetooth and localization.

It's called protect battery, under battery settings.
@Hamid Chikh, doesn't really work with charing the phone in the car for example. I just want a limit, that would the battery never exceed given percentage.

Motorla doesn't have this option. Did you just share a screenshot from Samsung device?
For that, you need magisk, with ACC (advanced charge controller) module installed
