[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.

In fact I was looking for an app that just avoids me to go through the whole menu (settings > battery > wireless quick charge/cable charge) each time I want to change the charging mode of my Galaxy S7 from normal to quick charge (cable or wireless mode), Does this just do that, and is it avoiding this and does it indicate on the homescreen in which mode it is set ?

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.

Xiaomi Redmi Note 10S 25W Quick Charge curve

Hi!
I've maneged to create a graph of the Redmi Note 10S's voltages and currents (etc) while quick charging.
I belive this data also applies to other Xiaomi devices using the 25W fast charge feature. The 60W and 120W versions of this can (probably do) work very differently.
Some explanations:
For battery current, voltage, and temperature measurements, I used "Ampere" from the Play Store.
For USB voltage and current measurements I used my Keweisi KWS-1902C.
You can see a drop in temperatures at 13%. I had to throw the phone into the freezer (pausing the measurements) to prevent premature overheating. So I could get some meaningful data out of my recording.
If more data is desired, please see attached .xlsx (or .ods).
Let's begin
Battery voltage, current, and SoC (State of Charge) by time (seconds since beginning):

Battery power and temperature by SoC:
Battery voltage, current, Input voltage, current by SoC:
Takeaway from all this:
At 40 degrees Celsius the battery officially "overheats" and charging power gets reduced drastically. But shortly after at 39 degrees celsius the phone says "ohh, it's cooled down now" and charges at full power. Not very sophisticated method in my opinion.
For the fastest possible charging speed keep the phone as cool as possible.
The battery voltage exceeds 4,5V during charging. According to the marking on these kinds of batteries 4,35V is the maximum voltage. Issue is that an aftermarket (a low quality one) battery may only be produced to withstand 4,4V max (4,35V marking) and that's going to cause fireworks sooner or later (if (when?) the separator foil inside the battery starts to fail, a short circuit will develop setting everything on fire). Please be mindful of this when browsing for a cheap replacement battery.
Properly fast (~22W) charging can only work until ~60%, after that voltage limit kicks in.
The phone uses an internal DC/DC converter to turn the 9V at the USB connector into some safe voltage (4,5V max apparently) for the battery. This converter's efficiency is measured (by me) to be about 90%. That's most likely false since at 22W 10% heat loss would account to 2W of heating power. That's simply too much, my measurement must be inaccurate.
Why we push 9V at the USB port you ask? Because the port can only carry so much current. 3A in this case to be precise. So if we want to increase charging power we need to increase the input voltage. After that the phone has to work it down to the battery voltage resulting in a peak current of 6A (being fed into the battery).
Correction: In the spreadsheet you can see at the SoC vs mAh deviation graph that the 100% capacity is marked at 4000mAh. This phone has 5000mAh of battery capacity. Why the difference? No idea. Still investigating.

Happy Halloween!
