Hi,
I have a question on how the X10 (or any other smartphone) detects if the battery is depleted.
Is this a software or hardware issue?
I have an X10 and it won't charge the battery via the USB cable.
I charged it with an external charger and I verified the voltage under load. The battery is indeed charged. But when I turn on the phone it will get to main screen (Android) and I see the battery icon as completely empty (sometimes full though) and then the pone restarts.
So it looks like when it gets to the main operating system something tells him to turn off because the battery is empty.
Any ideas?
What is the middle pin (between the + and - pin) for?
Thanks

It was working fine before I went to bed last night, then I let it charge for the night since that battery was at about 4%, But this morning it won't turn on at all. The battery feels warm as if its been charging but nothing seems to be making it turn on. Any ideas?

If it was my phone here is what I would do.
First I would see if the phone charges the battery by putting the battery into
the phone and plug the usb cable from phone into the wall charger or into
the computer.
If the display on phone shows a picture of a battery charging let it charge
for an hour more or less and try turning on the phone.
If the phone is not charging the battery I would purchase a cheapy battery
charger and battery combo on eBay.
You can find this combo on eBay for less than $8 bucks shipped for both the battery and charger:

(even if you decide to return and exchange the phone its still a good thing to have a spare battery and charger)
Check it out.
Good Luck!

are you on cm7? not sure about the s2 (never had the issue), but i know that on the infuse, there was a problem (or maybe it was intentional) with low power charging mode (phone wouldn't charge when off).
i think this can be solved by trying to charge the phone via your computer usb, as opposed to your OEM wall charger.
Thanks for the suggestion. It definitely isn't showing the picture of the battery when its plugged in to the wall or the computer. I'm debating the battery charger combo you linked.
I actually am. But I have it plugged to my computer and nothings changed.
Time for some trouble shooting.
Start eliminating possibilities. You need to determine where the problem is.
From what you say, it seems possible that the battery is completely discharged but not recharging. That could be a bad battery or it could be the phone.
If you know someone else with an SGS II, try inserting their battery temporarily to see if your phone will boot. If you don't know someone else, maybe you can borrow a charged battery from the store where you bought it.
Continue on until you pinpoint the problem.
Do NOT buy a "cheapie" battery for your SGS2. Unless you want to eisk causing damage. The stock battery for the SGS2 has NFC technology built into it. Using anything other than OEM could cause damage/performance issues to your phone, and void the warranty.

Have goh tried a battery pull? Unplug the phone, pull the battery and let sit for a few minutes to allow tbe IC's to discharge. Put battery back in and try powering up the device. Good luck.

Similar issue and got phone fixed finally
Have had similar issue as yours. Cable charger was plugged into the phone to be charged at night and was surprised to find that the phone became hot and battery was not charged at the next morning, in fact the battery level got lower than it was before charging.
Notes:
- ROM in use: AOCP version 7.2 (Android 4.4.2)
- Kernel in use: Version 3.0.101 [email protected] #3
Here are some tests done and the observations after getting a charger with a slot to place the removed battery for charging:
1. Charging via USB cable connected to PC:
- With the phone turned on, battery charging icon is only displayed after some wiggling at the charging port. The phone got charged further to 100% when the initial remaining battery level is 90%. However, when the initial battery level was less than 50%, the battery level continued dropping ALTHOUGH the battery charging icon was displayed.
- With the phone turned off, battery charging icon is only displayed after some wiggling at the charging port. When the initial battery level was less than 50%, the battery charging icon displayed only a battery level of 1% and the battery level did not increase at all after 15 minutes of charging.
Initially suspected that it was a dead battery issue and bought an i9100 battery, I thought it was a compatible battery at first. With the i9100 battery, I repeated the above tests.
2. Charging via USB cable connected to PC:
- With the phone turned on, battery charging icon is only displayed after some wiggling at the charging port. The phone got charged further to 100% when the initial remaining battery level is 90%. However, when the initial battery level was less than 50%, the battery level continued dropping ALTHOUGH the battery charging icon was displayed.
- With the phone turned off, battery charging icon is NOT displayed but the phone screen flashed continuously, and at times the phone is turned on automatically as the USB charging port is inserted. When the phone is turned on, the charging proceeded as the above sentence.
Upon searching the forum, I found that i777 has a different battery with NFC chip and i9100 battery has reported to cause issues during charging on i777 devices. There was also a Chinese forum which mentioned that the battery compatibility issues should have been overcome in ROM with Android version 4.0 and above.
I then bought a new i777 compatible battery and tested charging via USB cable. The observations are same as the first battery as at 1.
With the battery issues possibility eliminated, I approached a phone technician to examine the phone by telling him that the phone couldn't be charged and the battery level continued dropping even with the battery charging icon displayed. The phone technician then thought that the USB charging port to be the cause of the charging issue and replaced it. The replaced part is the small metal housing where the USB cable is inserted, and is replaced by heating the old metal housing and replacing it with new part by soldering.
The phone could be charged with USB cable as usual after the part replacement and all the batteries are found to be still working fine. Ended up with 2 i777 batteries and a i9100 battery, may be I could continue using this phone for at least another 5 years down the road.
Hello people, I have a strange problem, I have less than two months with my SE Xperia Ray, and always loaded with original charger , but about two weeks ago or something but the phone whenever it reaches 28% of battery status and jumps to 0% and off. the battery is completely discharged. Sometimes I'd see battery calibrator used but still the same, any suggestions you can give me if they had a case like this? thank you very much
Do calibration! Let your battery became absolute empty and phone will turning off automatically. Then connect the charger (!just charger, do not turn on the phone!). When batery turns full disconnect the charger, eject the battery for 5 minutes, then take it back and connect the charger again. Then it became full enter recovery => advanced => Wipe Battery Stats, then restart your phone and when your home screen appers disconnect the charger. Let your battery became empty to the end (!do not restart or turn off during this period!) then charge as always
So i just played with Custom ROMs to find the best for me...
But from one point my Phone f*cked up the battery detecting...
CM9 and CM9 detect the battery at 45% and then he Level instantly just drop to 0%...
I cant even restart my phone, so i guess the battery really went out...
So how can i fix, that the ROM would not detect it 45% but 3-4% ?
And let me fully chage my phone ?
Stock rom Always Detect it 100% and then randonly the phone shut down in random times (cuz it drops the level to 0%)
I've tried the "Fully-Charge, Fully-Discharge" But the ROM still detect the Battery wrong...
Even tried to delete the battery stats...
Any solution, or idea ?
I currently use CM with the built-in CM9 kernel...
I think its battery problem.use a new battery.ur prblm will be solved

How old is the battery? What charging cable are you using and what is the cable plugged into?
If the battery is more then a year old it could be 'tired' and not holding a charge correctly (trying another known good battery in your phone will determine this, as will trying your battery in another phone, and if it works well you may have more issues to deal with). If you got the phone second hand, you have no way of knowing the battery's history. Repeated overcharging is also not recommended, as well as leaving the battery in very hot places as it can damage the onboard circuitry in the battery.
Cheap aftermarket (non OEM) USB cables are not that great imo, they are generally not as well made and soon get loose connections, resulting in poor connectivity (charging with a bad cable can also damage the battery). Always use the original cable or a good quality aftermarket one, like Belkin.
Charging the phone from a USB port on a PC or laptop (and/or via a USB hub) is not as efficient as charging it directly from a wall mains USB adapter, because the power often gets interrupted. Ideally for the best charge you should turn the phone off and use a wall/mains socket USB lead, so as give a direct, constant, power supply to charge a battery. A typical full charge is done in two hours. If you charge this way and the battery still has issues buy a new one.

First of all, the Phone is manufactured in 11W41 (2011 Week #41) and the battery in 11W39 (2011 Week #39)
I use a tipical Micro USB charger which does not connect to the wall with USB but the cable directly integrated into the adapter...
And the phone's shipped official cable to charge throught my PC...
The battery worked fine before i forgot to delete battery stats and flashed a ROM...
After that, all ROM is getting fake battery data...
After using my phone i noticed:
-When the phone displays 70-80% charge, the battery actually have 10-15%
-When the battery reach 0% the phone not just jumps to 0% but the Phone shut down within a half second (as no more energy)
-When i charge it to 3-4% the phone show 80% again...
-So i can charge it to about 10 or max 15% when the OS detect 100% and does not charge it further more, which prevent me from properly re-calibrate the battery stats, cuz 10-15 will be always the max charge of the battery...
Now i'm looking for some kind of Mod / App that fake the Battery level to the OS (for example lock it to 5% and the OS continue to charge the battery) i know its dangerious cuz if i'm not aware i'll overcharge it and it will die permanently, but i have no better idea ATM...
Update: Sometimes after my phone dies from no remaining electron in the battery It displays 5% charge when i switch it on while connected to a charger (the only way i can switch it on) And starts to increase.. (5-6-7-8 etc..)
But sometimes it instantly jumps up to 70-80% if i think right when the screen switches of..
So i enabled "No-screen-off-whili-on-charger" and letit charging..
Will notice you about the result...

try reflash stock.ics ftf should fix this
Already tried, the Stock rom always showed 100% charge, and when the battery ran out, just powered off...
(Jumped from 100 to 0 instantly)
As i mentioned, in the reply you quoted, today it started charging from 0...
It went good, but somewhy, it just stopped at 26% and not a single volt went into the Battery...
As i Pulled out the Cable, the indicator jumped to 100 instantly...
Can you link several stock ROMs ?
I've tried with the 4.0.4 Android
but maybe the 2.3 can still work with it...

but i think theres some HW damage. even if not rhe battery maybe some config chip is broken or whatever on the board. normally flashing a stock.ics.ftf resloves all software issues, as its resets all stuff to factory..
anyway, here u can find links to other android versions: http://talk.sonymobile.com/t5/Andro...y-Bean-ICS-Ice-Cream-Sandwich-and/td-p/154389

One solution still, that my frind has the same phone as me, so when i meet him, he can charge my battery to really full and maybe when i insert it to my phone it might work...
Hello
A friend gave me a broken Xiaomi Redmi Note 4. The phone has a broken and bent screen and a battery problem. First of all, the battery has a capacity of only about 400 mAh instead of 4000 mAh (I checked with a Keweisi USB voltage meter).
Secondly, the phone without the charger connected turns on until it displays the "Mi" logo, then you can see the black screen and hear the warning sound of a discharged battery and the phone turns off. If I plug in the charger and try to turn on the phone, it turns on and works normally, the charger can already be removed. Of course, due to the very low battery capacity, it discharges very quickly and switches off when the battery is about 20% charged.
There is no doubt that the battery is defective. But I wonder if if I change the battery and the screen, the phone will work normally again, or maybe the fact that without the charger it turns on and off after a while is a bigger problem, for example the motherboard. But I think that if it was a motherboard the phone would not turn on at all. What do you think?

Hello
So my screen was broken and I decided to replace it.
I unmounted all the parts and remounted them very carefully and now I have a clean new screen ....
... but now the phone doesn't charge anymore. I tried several USB cable and charger, but the result is the same when I plug an USB cable :
- The phone vibrate and wake-up from sleep mode
- The batty icon shows the lightning bold on it like its charging
- But, the percentage charge does not increase even if I let it several hours
- When I go in Battery settings of Android, it says that battery is not charging.
- When the phone is turned off, I only see the battery percentage level and NOT the lightning bold
Do you know how I can detect the default part to replace ?
Thanks again for any help.
I Think the battery is damaged.
I used Ampere and the usb cable is well detected but battery is still discharging.
I ordered a new one.
