Does this app work on S2?
i had it on my Hd2 and the mA when it was sleeping is between 2-7mA but on s2 it average idling mA is 200+
Battery monitor widget pro doesn't get mA current readings on the sgs2 cause the phone doesn't output current, so battery monitor estimates its own current readings and shows those instead. So they aren't true readings.
It supposedly takes the rate of level drop of battery percent, with the battery size in mAh plugged into settings by the user, and extrapolates mA readings from that. Either way I wouldn't our much faith in the mA numbers.

my battery is standard galaxy s 2 1650mAh
and i've gone to /sys/class/power_supply/battery/voltage_now file
and it show value 3687574
correct me if i'm wrong, that value is in micro volt right?
and full charge value should be 4million++ microvolt
but my android battery indicator shows 30% left
it looks like the battery indicator does not report the correct value
Yes, full charge value is 4 million+ Volt, right, there are a lot of apps which shows the current voltage actually, I personally for me use the Clarus Battery as it is simple in text mode. Battery Calibration by Nema also shows battery voltage, but that is when you open the app, not as a widget like Clarus
Regards.
if the full charge is 4++volt
i check my current voltage is 3.6 volt
battery indicator shows 11%
if i calculate correctly
3.6/4 = 0.9 = 90%
why does the battery indicator show 11% and not 90%?
how does the android battery indicator get's calculated?
0% is not 0v.
The battery cells must have a small charge all the time. I think about 2.7v or something is minimum voltage.

i've jz got a shut down when my battery is at 3.51V
battery indicator show 1%
it's far from 2.7v point
i think there is something not right on the way it calculate the battery %
All, sorry for the semi repost, but I got no answers from the other battery threads.
Can other people post their battery voltage plots? See my voltage plot below. First off, I realized the HOX+ uses a 4.3Vmax (or 3.8Vnominal) battery vs. 4.2V (3.7V) on the HOX and most other phones. The higher voltage gets us more mAH and WH, but does pose some risk on reduced battery cycle life and stress to the Li-Po battery.
So my concern is the quick drop in battery voltage after full charging to 100%. You can see in the plot below the voltages reaches around 4295 mV, but quickly drops to 4250 mV while still on the charger. Maybe this to protect the battery? But I also noticed that once I unplug the charger, the voltage quickly drops below 4.2V within minutes.
So my questions is, is my built-in battery not up to snuff to handle 4.3V? One thing I've noticed is my phone goes from 100%>96% very quickly, usually within 10-20mins, even it's idle (Screen off) etc.
I'll like to see battery voltage plots from others to determine if my battery performance is an anomaly or not.
Also, one other note. My Battery Monitor Widget app reports 2040 mAh battery and not the 2100 mAh that is advertised. Like to see if other people are seeing this as well.
Charging the poco fone using the bundled charger charges at around 4,300 mV. Is it healthy for the phone battery?? I use accubattery app and it shows this voltage in red colour, which makes me concerning about the longetivity of the battery life...
POCO F1 supports Quick Charge 3.0 featuring INOV (Intelligent Negotiation for Optimum Voltage), which allows for a fined tuned power output and a more optimized charging cycle.
INOV has the added benefit of being able to dynamically adjust the charging voltage over the battery charging cycle. As a battery charges up, it slowly draws less and less current, which is partly why it takes longer to charge the last 20 percent than the first. Qualcomm states that its new technology allows the phone to request just enough voltage to reach the desired charge current, thereby maximising efficiency.
This is useful as it reduces the amount of energy wasted during charging. Previously, extra power not used to charge the battery would be lost as heat, warming up your phone and reducing the longevity of the battery. By exerting more control over charging efficiency, less power is wasted, resulting in less heat.

Thanks. But Qualcomm doesn't say anything about the health of the battery.i have observed the phone during charge Cycles. It charges at higher voltage and slightly warm. But I'm concerned about the li-po battery longetivity. I would even switch to a 5v- 2Amp charger to increase the Life Span of my device as it takes around 30 - 40 minutes more which isn't a much difference as I have that much time to charge unless necessary...

Charging slowly the battery does not means that you are increasing lifespan of the battery. Charging slowly means high temperature for longer time = Less lifespan. I suggest to use a QC4+. It keeps temperature lower than every other charger. I'm using it since 3 months and temperature on charge is ~30-32 degrees on idle and ~36 while using it

Hi guys does anyone know how we can limit voltage when we charge ur phone?
What i use is rooted phone with ACC + AccA ront end but some bug you always have to check because most time AccA doesnt apply limit voltage as i ask.
Any better solution?
Why you need to limit the voltage? If you want to help battery to stay in good health for longer you should limit the charge current instead. Easiest way to do that is to use older charger with lower wattage. I usually charge my pixel 6 from my laptop which has type c ports with usb power delivery support and are limited to 12 watts so charge current never exceeds 2.1 ampers. I have also tested my old power bank and cable and there power is limited to even lower 7.5 watts or 1.5 ampers of current.
On battery university they said, the voltage from the charge is the problem not the amp speed, for example when your phone is at 3.8v(30%) and you charge with a quick charge 3amp at 4.05v(not 4.25v) you quickly recharge until 60%(4v) and you slowly and you reach 4.05v(+-70%) and you can let your phone charging longer you want the voltage never go over 4.05v and at 4.05v the said atfter 2000 recharge cycle you still have 90% of brand new battery capacity.
Your phone said full charge at 4.25v but with lithium ion it overcharging and that really dommage you battery life.
So in real is not the % of capacity because when you charge your phone to 80% diring the charge process the voltage use to charge is 4.35v and that is bad for the battery
BU-808: How to Prolong Lithium-based Batteries
BU meta description needed...
batteryuniversity.com
"Every 0.10V drop below 4.20V/cell doubles the cycle but holds less capacity. Raising the voltage above 4.20V/cell would shorten the life. The readings reflect regular Li-ion charging to 4.20V/cell."
I seem to get reduced maximum capacity even after fresh battery replacements.
Most recently I purchased a new replacement battery from iFixit. With this new battery, just like the previous one I bought a year ago from Amazon, my phone charges the battery to a what seems to be around 80% of its capacity. The maximum voltage when reported charge reaches 100%, as reported by the phone, is 4.225V (according to multiple apps). Capacity as measured by AccuBattery is around 80% or 2800 mAh.
I've tried many things, such as the battery calibration multiple times (both method 1 with USSC codes, and something like method 3 which iFixit recommends), without any major apparent improvement.
Things I am wondering:
Should the battery voltage when at 100% charge be closer to its rated 4.4V than the maximum 4.225V my phone is seemingly able to reach?
Can I expect to see improvements if I keep going through a few cycles of battery calibration and full charge/discharge?
Is there any other way to reset the phone's perception of battery capacity or wear than the battery calibration options?
I found another thread with a similar description to my own experience here.
In 3 years I have replaced battery 4 times, now something odd is happening.
I'll make a note to dig out my old USB tester and check how much total juice is pushed into the phone with a charge from <5% to 100%.
More details of my battery history for more background and for anyone interested:
I used the original battery from purchase in late 2018. My charge pattern for the first 2 years was typically charging to 100% every night, and topping up during the day as necessary.
During winter 2020 it performed terrible in the cold (not any extreme cold, only around 0 C), and once drained from around 80% to 35% in less than an hour of continuous use (photos, filming) and then died. After this I changed my charging pattern to where I was keeping the phone from exceeding the 70-40% range as much as possible.
In December 2021 I purchased a replacement battery from Amazon (supposedly original). The original battery was reportedly at 80% capacity says AccuBattery. How reliable that measurement is I don't know (it is all data reported by the phone itself as far as I understand), but the capacity had gradually decreased over the three years of use. I can't recall the voltage readings though, and I don't seem to have any screenshots saved from that view.
The new battery didn't ever seem to be able to exceed the capacity of the 3-year-old original battery (which had gone through over 1,100 charge/discharge cycles as tracked by AccuBattery) that it replaced. It's more stable (especially in cold conditions) but has not brought any increase in usage time compared with the battery it replaced.
With the now 10-months-old Amazon battery, having gone through less than 400 charge/discharge cycles according to AccuBattery (which is relative to the max capacity of approximately 2800 mAh or 80%), my phone in the past month gave me the pop-up notice indicating a poor battery. The capacity reported hasn't changed much over these 10 months of use.
Update with USB tester and comparison with a Samsung Galaxy S5 Neo.
TL;DR: 2800 mWh is the new 3500 mWh
First, S5 Neo.
I have an old S5 Neo, last of its era of Samsung phones with easily replaceable battery. I purchased a new battery for this phone from iFixit in the same order as the S9+ replacement battery.
S5 Neo's battery is rated at 4.4 V (3.85 V nominal) with a 2800 mAh capacity, or 10780 mWh. Depleting the battery and making sure the phone would no longer switch on with the power button, I charged it from 0% to 100%.
After slowly charging for 3 hours at just below 4.8 V and 750 mA for most of the time, the USB tester showed 10780 mWh, and the phone showed 92% charge. At the 3h 30min mark, shortly after reaching 100% (I didn't catch it perfectly), USB tester showed current had dropped to 350 mA and total charge delivered was just over 12000 mWh. After another 10-15 minutes the charge current dropped to zero and total power delivered showed 12326 mWh.
The S5 Neo phone, using the app GSam Battery Monitor while the phone is otherwise idle, it shows an internal battery voltage reading of 4.38 V when fully charged, still plugged in and trickle charging. Once it's saturated (charging icon disappears) the voltage drops to 4.33 V.
Going by the USB tester results and progress shown by the phone, and with the assumption that the battery is able to be charged to its full rated capacity with this old phone, the battery charged to capacity with an efficiency between 87.5% and 92%.
I also captured a few mid-way readings. Here is the complete list of my captured readings including comparison to rated capacity assuming perfect efficiency (with extrapolated total charge for levels below 100%):
100% (charging current at 0.0 A)12326 mWh~114% of rated capacity100% (still charging)12062 mWh~112% of rated capacity92%10780 mWh11717, ~109% of rated capacity81%9291 mWh11470, ~106% of rated capacity62%6440 mWh10387, ~96% of rated capacity33%3160 mWh9575, ~89% of rated capacity19%1868 mWh9831, ~91% of rated capacity
The extrapolated charge to reach max rated capacity is increasing as charge level goes up, which I think is kind of expected. Conversely, the efficiency is a little lower than I would have expected. Still, the total power required to reach 100% exceeds the rated capacity by a fair margin. Better still, the phone itself reports a battery voltage near the battery's rated 4.4 V.
Second, S9+.
As mentioned in the original post, the internal battery voltage max reading is 4.22 V, and the capacity seems to not reach the expected level. Checking the Battery status option of Diagnostics in the Samsung Members app to check the battery, it shows it is in "weak" condition. Resetting all the battery related readings using USSC codes (see battery calibration) doesn't seem to change anything.
The battery is rated at 4.4 V (3.85 V nominal) with a 3500 mA capacity, or 13475 mWh. With fast charging disabled, and after draining the phone until it powered off and would no longer power back on, I started charging via the USB tester. I'm using a Samsung travel charger this time, which delivers a little more current than when I charged the S5 Neo.
Charging starts out at just below 5 V and 1.5 A. Current quickly drops to 1.172 A, and somewhere between 33% and 50% it drops to 1.072 A. This current is stable until beyond 81% and then starts to gradually decrease throughput the rest of the charging cycle. (Actual charging current is slightly lower with screen off vs screen showing current charge level.) This I believe is indicative of the battery capacity (or perhaps rather the phone's perception or expectation of the battery capacity) is below its typical levels. It could also be a difference in how the S9+ charges compared with the S5 Neo, or perhaps less likely a difference between the chargers used, I can't really know for sure with only my two samples. In comparison, the S5 Neo kept charging at essentially the same current level between 0% and 92%.
Again, here are a few mid-way readings, as well as the extrapolated capacity assuming perfect efficiency:
N/A13475 mWhnever reached100% (charge current at 0.0 A)12341 mWh~92% of rated capacity100% (first reached)11982 mWh~89% of rated capacity92%11398 mWh12389, ~92% of rated capacity81%10053 mWh12411, ~92% of rated capacity62%7646 mWh12332, ~92% of rated capacity50%6174 mWh12348, ~92% of rated capacity33%4100 mWh12424, ~92% of rated capacity
Oddly consistent, this ratio between charged power and percentage charge, at around 92% of rated capacity throughout almost all of the charge cycle.
The total power required to reach 100% is very disappointing. Even assuming perfect efficiency, it is well below the battery's rated capacity. Assuming similar efficiency as the S5 Neo at around 90% translates to roughly 80% capacity at full charge. This mimics closely the estimates from AccuBattery, which shows 78% capacity after 12 "full" cycles.
To reach a "saturated" 100% requires equally much power for the S5 Neo as for the S9+, even though the S9+ should have a battery with 25% more capacity.
Now that I have externally validated that my 4-year-old S9+ is only ever able to charge my fresh newly replaced battery to 80% of its rated capacity, I suppose the optimistic view is that it's now a forced charge limit for substantially increased battery longevity. While this is functionality I do want, it is something I'd prefer to have the option to use, and with the ability to top up to 100% when necessary.
If I have the opportunity, I may drop by a Samsung service center and ask if there's anything I can do to reset the battery status, or retrain the phone's perception of battery capacity.
Thank you for coming to my TED talk, and have a great day.
