Create a ‘SOTI package’ that transfer the tar file The first thing to do is to open the Google Play Store on your device.Press the back button as often as you see the your defined profile.Applies the Scan2Deploy profile using the proper method for your EMM: Check field "Use root" and put the following line in the "command" entry:Įcho '4200' > /sys/class/power_supply/battery/voltage_max Confirm your task name.Ĭlick on the "+" button in the bottom right corner to choose an action. Chosse "Any" and press the back button.Īdd a new task and name it like you want (i.e. Now you have to specify the source of power supply. Choose "state" and then choose "power" and again "power". Install the app "Tasker" and do the following:Īdd a profile by pressing the "+" button in the bottom right corner. I found that I can stop battery charging by changing value of '/sys/class/powersupply/battery/inputsuspend' from 0 to 1. The default value will be reloaded So after every restart of your phone you must edit the file again. The reason I have written in the first sentences.īut what happens if you restart your phone? It’s very important to take the following notes: The battery.png and batterycharge files are deprecated in 6.0 and are replaced by png (multi-surface image) with a mandatory 6 frames, which are hardcoded in Android. This solution is a much better solution than cutting off the pure percentage. First you will need to download all of the default battery. My system shows a percentage of 89% when reaching 4.2V and the charging progress is complete. You can check this with many apps like CPU-Z. So the battery never sees a higher voltage than 4.2V. I have rewritten this file with the value "4200". This value is the charge termination voltage in mV. In my case this file contains a default value of "4350". Because the Shell just got me 'Access Denied' errors. The file "voltage_max" is the file you have to edit. Best way I found to edit files inside my app was using the Device File Explorer of AndroidStudio. Without root you don't get access to system relevant features.Īnd there you can find some meta data about your battery. The charge termination voltage you can look up in the picture above (SoC curve).įirst you need root access. The charge percentage is the percentage of your full capacity measured in mAh. Set the limit of the CHARGE TERMINATION VOLTAGE and NOT the maximum percentage of charge. If you want to read more about the technology of Li-Ion batteries, don't hesitate! So it is useless to charge the batteries to the end to get 100% unless your battery life does not affect you. The state of charge (image from Silicon Lightworks)Ĭurve shows that there is not much energy needed to get from 4.2V to 4.35V. In case of applying a high temperature in combination with the mentioned high voltage the battery life will be drastically shortened! Why? When charging, the voltage of the battery near the defined percentage is very high (in my case 4.35V). 90%) This solution may extend the battery life but not really effective. The offered solution of many apps is to stop charging when reaching a certain percentage of the full capacity (i.e. The problem of Li-Ion batteries is the faster aging when applying a high voltage in combination with high temperatures Level 2: Its voltage rating is same to that of Level 1, but the current and power ratings are 200 A and 90 kW, respectively. Level 1: The rated voltage, current and power ratings of such systems are 450 V, 80 A and 36 kW, respectively. I have tried several apps to improve battery life but I did not find a useful solution. DC charging systems are also categorized into three power levels.
