Sometimes state of charge estimation algorithms have problems with current battery level estimation (because of battery aging, environment temperature jumps, etc.).
To have some reference on available charge level user can take into account current battery voltage state.

Hello,
Is it possible that you add a feature to calculate the percentage of battery based on max and min voltage that an user can insert ?
For exemple on my phone the min voltage is 3.2v and max is 4.2v so it's easy to calculate the right battery percentage to display in
notification area.
Thanks !

Thanks for your useful app.
It makes me wonder about the meaning or value of the result.
For example, I have two Galaxy Tab S2 (one 32g, one 64g) SM-T813.
One shows a current voltage of 3984mV, one shows a current voltage of 3851 mbps, the difference varies as much as 400mV depending upon the time checked.
Is there a value or significance to one tablet always running with a slightly higher voltage (same Rom/ updates and apps running); or is this just a variance within operating tolerance?
Thanks in advance for your answer and insights.

Hey there... Really usefull app, thx for your work.
Is there a chance to add a shutdown function to your app?
We really need it for our accu-mod and %-mof for our bacon device, see here: https://forum.xda-developers.com/on...neplus-one-t3492926/post75946046#post75946046

[Apk][Share]AccuBattery, the best battery monitor!

In the name of GOD
Hello community!!
I found a battery monitor in the playstore. It is so good!! So I'd like to share with you people! It's called the Accubattery.

Almost every phone contains a little bit of hardware that can measure the current flow into or out of your battery, in mA or µA. We track this data continuously, but also segment it by screen state (on vs off) and which app was in the foreground. With this data, you can see clearly how your battery was used.
Battery life is probably the most common concern for smartphone users: some are finding it hard to get through a full day on a single charge, others find that after a year or so of use, their battery drains much faster than before, and the issues just keep lining up.
AccuBattery is a relatively new battery life monitor for Android devices (it supports the latest Samsung Galaxy S7s, Google Pixels, and so on) that focuses on accurate battery stats, but also on a research-based suggestion to avoid fully charging your battery.
AccuBattery allows you to set alarm that you actually charge your battery to 80%(Can be modified) and comes with clever tools to let you know when you've reached that level, so that you can unplug. This way, you can get the full 500 cycles(More than 1000, if you charge from 30 to 80 ) out of your battery, until you start to see a noticeable drop in battery life.
I still have my two year old Z2. It still holds battery like a new phone( with slight less capacity due to heat generated due to flashing roms). I used to charge my phone between 25%-80%.​

Press thanks if I've helped you!!:fingers-crossed:

Inspired by AccuBattery I have created a raspberry pi 3 image which can stop charging your phone automatically after it reaches a certain percentage. Works on non-rooted phones.

Looks very nice!

Instant Charger will automatically activate when you plug the charger.
HOW TO USE: Press on the "Start" button, the app will automatically optimize the phone's charging capabilities by: killing all background apps, turning off WIFI, Bluetooth, and Location if you choose to, which makes ... faster charging. If you want to stop it just press "Stop" and all signals will be restored.
FUNCTION:
* Battery charger not only faster, but also extend the life of your battery.
* Displays the battery's basic information such as: Temperature, Technology, Voltage, Health, Plugged, Charge
* Beautifully designed, clean and simple to use.
* Application is FREE forever!

Yes that's a temporary solution for faster charging by limiting background drain during charging, but how does it increase a battery's life? It's unclear to me whether OP means that the battery will drain slower or it prolongs the battery's health. But whatever he means I don't see how it can achieve either, judging by the description the app doesn't do anything extraordinary to lower your battery's drainage or increase its life.
Furthermore, I don't use location or bluetooth and I doubt merely disabling wifi and clearing background apps would result in 3x faster charging. If anybody tries this app, please inform if it somehow extended your battery life and charged 3x quicker.

High Battery Voltage

I just charged my P4a to full capacity and monitored it with Accubattery. I have found out that final battery voltage is quite high, is it normal for battery used in this phone? Does Google use this high voltage to increase overall battery capacity at the expense of battery life? Thank you

What is making you think 4.455v is high?

I've been reading that the most of Li-Pol batteries have maximum voltage of 4,2 V. Also the red colour of the graph little bit intimidate me.

What makes you believe AccuBattery (cough), yet another generic battry app, and related 'red' alerts have any relevance to the overall health of your device. Don't take the bait, mate.

the batteries tend to go beyond what is indicated, it is normal, so it is advisable to charge a maximum of around 80%, to keep the voltage below that threshold

I stumbled on this thread when checking what other P4 threads I was missing out on. The voltage is very transient, and you also have to be careful to distinguish between your battery voltage and the measured voltage in the system during charging.
NB: all the following is dependent on root.
The dumpsys batterystats includes lines for "volt=???". If you extract all of these and convert the ms offsets to times, you will get graphs like the following
I can only assume the numbers should be divided by 10 to get to the mV You can find this graph at Currently Running>Battery>Battery History Extras>AUTO-WIDTHx4>Graph of Explicitly Recorded Values [VALUE]>NONE - Direct Values Logged>Battery Volt [VOLT].VALUE
Also from the dumpsys, you can get the charging status (as well as battery power and with some calcs, the drain rate) which gives me the following for the same period as above
Pretty clear the measured "volts" jump up during charging. NB: I am using an old low wattage charger, not the fast charge.
The above graphs were generated using my app TeMeFI, with some details on the above features in the post1 and post2. There are >100 other graphs from the app, including the discharge rate over time. Ands you can also extract the data frommwhiuch the graphs are based.

Require A Battery History App

Back during MIUI 11 or Any Android version before 10 (Pie) , there used to be a handy battery history which showed phone awake states. Basically it was a 1:1 correspondence graph where it showed if when your screen was off, did your phone sleep too. It also had other bars for WiFi, GPS.
This information was useful for me to diagnose a wake lock that was being created due to a faulty Charging Port. All new Battery Stat apps are overly simplified and do not have that same graph/chart.
Does anyone know of any app, no matter how old or ugly if it can give me that 1:1 graph? I will attach a sample picture below.

@Alrich As far as I remember, TeMeFl by @DiamondJohn also provides a lot of battery information including graphes. However, I can't assess if this is what you require.
[APP][TOOL] TeMeFI comprehensive system Administration
TeMeFI This app provides/returns a bucket load of information regarding your device and the currently running ROM, and much, much more. And hence the name "TeMeFI"; as its Too Much F????? Information. The F stands for whatever your comfortable...

There are a heap of wake-lock graphs, signal strength WiFi etc etc etc. There are summaries or you can save them off, and open/view/analyse them up on your desktop
The majority of the graphs were release in this release: https://forum.xda-developers.com/t/...e-system-administration.3806260/post-85153055
But the battery drain graphs AND Doze graphs/control (which can block some wake-locks, and I personally found it to help the most with battery drain) were there in a much earlier release.
