Hi, on my notes has failed circuit that detects the temperature of the battery not being detected then that is read as-20c.
At this point it is impossible rcaricare using the battery because the phone detects that the temperature is too low for charging and I have to charge it with an external charger. As the rest of the phone is operating at 100% wondering if it was possible with a modification to the kernel reading this fool doing so recharge the battery to the phone. Obviously I am not able to make this change and I'm going to guess that both the kernel to communicate that value to the processor. If someone is able to solve the problem would avoid even the purchase of an additional battery to be exchanged while reloading the other. For me it would be fine even if the message remains too low temperature break ... important to disable the battery charging.

Good fellow, again around here bothering me. I tell the 19 May last buy a Galaxy S2, came factory sealed, in fact I remove the seal, the question is that since last Sunday something very strange happens to me: charge the battery at 100% and start using the phone normally when it reaches between 30% and 40%, begins to fade as the lighting of the tactile buttons and screen, that when I have activated mobile data and the need as more cel battery consumption between the headed or cel energy loss and lose the signal goes out, if I disable mobile data if it holds until the battery to discharge, but connect with the phone off and make me inmediantamente load of 30% when it is assumed that the cel was shut down because was downloaded.
To tell a friend tell me that you step on something like a SE x10 and it was the battery with a voltage problem. Then you believe it is, that the battery is damaged and not the power to mobile or mobile to be problem?
I wonder I did, I did the following:
Calibrate the battery with CWM (I deleted the batery Stats)
I did 3 complete cycles of battery
With a multimeter measures the voltage of the battery and gave me when it comes to 3.80% by giving the prooblema and 4.10 with the battery fully charged.
To rule out problems with the loader, load it with the PC, the battery lasted a little more me, but I spend as already mentioned.
I flashed 5 times and install the ROM Andyx
If I connect to the socket and use it although it is very hard not pass this probleme when I use it only with the battery, when it comes to the percentage of battery I have before mentioned active data and give it a very intensive use (internet, games, benchmarking, etc.).
Since I bought I notice that my view is loaded very fast and just as quick to download, but until Sunday presents ehstos symptoms.
They think it's worth it to buy another battery or mobile internal problem?
Probe version of ICS LPJ European modem with LPS, the LPW and now I have the ROM ROM Andyx Extremev0 Apollo kernel and all feel the same, with percentage and holds more than others, but all happens to me .
Please help and many thanks in advance.
let me say one thing first: i don't want to discuss if resetting the battery status database helps in any way to prolong the battery life of a phone or such, i have a different issue with the battery management under android:
i have taken the guts out of an AN1 Smart Watch and used them as a tiny touch panel in an appliance. in order for it to run without a battery i have connected a little voltage regulator that converts DC12V to DC4V and feeds it right into the + and - Pin of the battery contacts. This way i can start and run the device wihtout any battery in it, which otherwise is not possible when trying to run it from USB power, even though i haven't seen the device pull more than about 300mA at most.
the device turns on and runs just fine, but what's bothering me is, that the battery charge indicator is counting downwards even though the voltage stays constant and obviously notthing really is being discharged since there is no battery.
i don't want to re-insert the battery and run from usb power as the battery will certainly fail within only a few years and i would really like the whole thing to run a bit longer than that.
is there any way i can re-set the battery countdown or disable it entirely? if disabling the simulated drain is not possible, resetting it should be possible while the device is running. i don't want to reboot the thing every day just to reset the battery stats or anything like that.
hope somebody can help me out here.
i currently have the AN1 running to see what's going to happen when it reaches 0% ..
regards

so here is what happened... the battery was constantly "discharged" until it reached 15%. it then showed the "please connect your charger" message but stopped dropping the battery level.
would still be nice though have a possibility to prevent this message from appearing. even though it is not as critical anymore, as the device will be running 24/7, so unless there is a power outage, this message only appears once and that's it.
i have attached a screenshot of the battery statistics with a power supply connected in place of a battery..
This is a defect I have observed all the way from Android 1.6 to Android 5.1.1, and I cannot understand how it can still be there without ever getting repaired.
The problem is that the battery indicator shows a positive number, for example, 8%, although the battery is actually at 1% and the phone will shut down any moment now.
This alone would be bad enough, but it gets worse. After the phone shuts down on its own, either due to an immediate, disorderly power cut or by performing an orderly Android shutdown, Android should have registered the obvious, namely that the battery is empty.
However, it does not. When I connect the charger and start Android, it still shows 8% charge. I have just tested this again three times in a row with at least one orderly shutdown on my latest phone, a OnePlus One running CyanogenMod 12.1, and it never went below 8%.
How can this be? How difficult is it to program that after a shutdown due to an empty battery and a restart one minute later the battery is indeed empty? It is not physically possible to charge a battery from 0 to 8% in a minute. It would explode if you tried.
Do the charging electronics not store and provide information at least about the very recent charging history? And can the phone not evaluate the battery voltage, which it measures? At least when there is no load on the battery for a little while, its voltage and its temperature allow to determine precisely whether the battery is empty. Why does the phone not do that?
Needless to say, this defect is damaging. To know how soon the phone is going to shut down is one of the most crucial bits of information for every phone user. To show the user 8% while already shutting down is beyond stupid, it is derisive.
I have something in my head that I call the idiot bells. They ring when I notice idiocy in my surroundings. And whenever I see the phenomenon described above, they ring loudly.
Can anyboy who really knows how Android and the charge electronics work explain what is happening? Or is it just the ordinary idiocy that we have to keep living with?
Do not suck nonsense replies from your fingers. If you don't know anything reliably and in detail, keep quiet.
Hello, I have an older tablet that has a busted charging circuit. The way I get around that is that I connected wires directly to battery and I charge it externally.
The problem is that android can not detect this charging and I have to keep rebooting it to update the percentage. Android will not allow percentage to rise while not charging (for obvious reasons), even though it can detect rise in voltage.
I need something that would either keep resetting battery percentage without rebooting or change the algorhytm so the percentage is purely voltage based.
Thank you in advance for any tips for how to do this.
P.S.: The tablet is running a rooted kitkat, also I really do not care that this is "potentially dangerous".
Got this device around a week ago and I'm finally daily driving it. I've noticed a big issue though... I can't charge the device past 80% when its turned on. It stops itself from charging it seems like. I have to turn off the phone completely, and plug it in when powered off to get it to 100%.
Is there a setting I have checked or something? maybe a Kernel Tweak I don't know about that could be causing this that I could change/reverse/modify?
Thanks!

Turn off optimized charging.
ohhhhhhh. Epic. Thanks
It's not a good idea to charge with screen on especially in high temperatures or in direct sunlight. You can cause hardware damage like this... auto thermal shutdown may not engage fast enough to save the device.
In general charging while using skews the charging curve, increases charging time and battery stress. These phones have a fixed heat sinking capacity which cases and glass screen protectors further compromise.
Constant operation with battery levels near 100% will impact battery longevity noticably.
Keep watch for any signs of case bulging. It indicates battery swelling/failure. Replace it immediately if this happens. Other signs of a battery failure are a sharp drop in capacity, erratic fast charging or failure of fast charging to engage. A swollen battery can destroy the display.
The risk of a thermal runaway event increases exponentially with a failed or degraded Li.
Replace them when their capacity falls below 80% of new to avoid a failure.

99.9% of the time I'm charging, the screen is off and I'm watching tv before bed. I'll unplug at 100% and go to bed. I also won't plug in until I'm under 15%.
I work in cell phone whole sale and repairs, so one thing I understand well is taking care of a device.
But, disabling that setting recommended above, it still stops charging at 75% entirely and never goes to 100 unless I turn it off entirely

If the screen is on it may not charge at all.
This is normal.
Cycling the battery like you do stresses it and will reduce its lifespan.
Li's like frequent mid range power cycling.
Not under 30% or over 80%
If it didn't use to behave like this the battery may have degraded. 1-2 years is a typical lifespan for a heavily used Li. Approximately 200 full charge cycles.
Replace when it degrades to less than 80% of its original capacity to avoid a failure.
This phone has only been out since January 2021, so its not a batter degrade issue. Plus, it was pulled brand new out of the box like this. You also didn't read what I said. I'm not using it while charging at all. Its sitting on a table next to me while I'm watching tv or gaming on my PC/Switch. I'll check it once in awhile to see battery percentage and it will stop at 75%, then discharge as if its not plugged in at all. I have to turn the phone OFF COMPLETELY to charge it to 100% once I get to 75%
I'm assuming software issue. when I had GSI roms on the phone, it worked fine.

Li batteries can fail at any time.
Symptoms; diminished battery capacity, erratic fast charging. Any signs of phone swelling, usually the rear cover is a battery failure in progress. Replace immediately.
If the phone is drawing more current than the charger and/or the power controller can supply, it will drain the battery.
It may be a software, firmware or hardware issue...
Check all settings, disable all power management. Enable fast charging (toggle on/off 3 times then leave on).
Clear system cache and do a hard reboot.
Return associated updated apps to their factory loads.
If you did any major firmware (OS) updates do a factory reset.
A defective/improper charger or cable; try known good Samsung charger/cable.
Defective C port PCB.
A failed mobo.
Time to send it in for service or replacement.

It's a standard OnePlus feature at work.
