So I'm running my aria on CM7-07282011-Nightly. I'm having battery issues, not battery-life issues, but general battery function issues. My stock battery died, then I bought two identical 1500mah batteries, which I have been charging with a standard Li-ion smart charger which I normally use for battery packs I build for various other projects. I just charge one battery while I use the other battery. Anyways the problem is that my phone's battery meter will never go over 80%. I boot up on a fully charged battery, and after two or three minutes have passed(when it first boots up it just shows the % it was at when I took the other battery out), the phone reads something like 74%.
I've thought maybe there was just a problem using two different batteries, so I tried charging one of these batteries in the phone and of course they stop a little above 70%, and sometimes the battery even drains while plugged into, well, any, of my 4 AC wall-plug type chargers or my computer.
I've tried wiping the battery stats, but it didn't do anything, and all the calibration methods I see say to charge until it's at 100%, which I can't get to...
I just wish there was a way to plug in an externally charged battery and reset the battery meter and force it to recognize whatever value is actually 100%....I've searched these forums and googled for two days and found no solution.
Does anyone know how I can fix this??

I'm not sure if there is anything you can do about it. There's almost always going to be some quirks with third party batteries.
A tip is never get 3rd party batteries and the batteries we use love charging so charge whenever possible because if you let your battery die before charging waste builds up and leaves less space for charging.
Signatures are fancy.
well, the phone works as long as if the battery has been charged to 100%, so I just wondered if the was something I could do...
So even if the batteries work a long time when fully charged from my external charger, there is no way to fix the battery meter? If I continue using it normally would battery stats eventually callibrate? they are good batteries...just seems like a software problem to me
Where did you buy the batteries from, E-bay??? E-bay and other on-line markets are loaded with Chinese knock-off batteries & SD cards that are fakes and/or not to manufacturer spec products.
If that's what you have, you can't expect the phone to "fix" it.
Battery stats do take a few days to calibrate, but I believe it should still show 100% when charged, if you have a real battery and not something out of spec.
I don't know what the manufacturer specs are, but a fully charged battery reads 4.2v, well within standard Li-ion open-circuit values. There is nothing wrong with these batteries....

Problem is that the percent battery available is not determined my measuring the cell voltage, rather reading a value out of the fuel gauge built into the battery pack. Li-Ion batteries have a rather flat discharge profile then crater at the end, making the cell voltage an unreliable predictor/measure of battery capacity.

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:
http://www.ebay.com/itm/1800m-BATTE...045605?pt=PDA_Accessories&hash=item43aa9a4465
(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.
Okay so I've this problem where my battery discharges while charging!
I had this problem since wednesday that time I was on stock... So I thought flashing a custom ROM now as of now i'm on SonyStyle still the same problem,
let me elaborate my problem a bit more
-To monitor how much current is discharging n charging! -498 mA while discharging n -298 mA while charging it normally
-So next thing I tried is to charge it while being switched off, most of the times it wont charge n when it'll charge it'll reach some point n starts discharging! Discharging even when its off and plugged to the charger! BIZZARE isnt it?
-Now in order to put it on chrging i've to reboot it couple of times untill battery monitor widget shows +current... N when it reaches 100 it'll begin to discharge like it'll be empty in 1nhalf hour
-ALSO I'VE TURNED OFF ANYTHING THAT SUCKS BATTERY! AND I'M NOT USING MY DEVICE WHILE CHARGING! ALSO IT DISCHARGES WHILE BEING ON CHARGER IN A switched off state.
these things i've already tried
-Flashing custom ROM
-Putting my cell on powersave CPU governor
-undervolting
-charging using USB
-CUSTOMER CARE CENTRE only resets the software
I'M SO FRUSTRATED THAT I'LL BURN THIS CELL INTO ASHES! Anybody help me before I kill thislil fellow!
You might try resetting your battery stats on clockworkmod or xrecovery. Charge until 100% and let it discharge naturally to switch off, allow a few days of charge cycling and it should be ok.
Lipoly batteries dont trickle charge. If you leave your phone on charge for 8 hours it will just switch off the charger, discharge for awhile and then switch back on the charger. Most take 1 to 1.5 hours to charge, so if you leave it plugged in you will be charging/discharging about 6 times in that period. Lipoly have a limited number of charges before they diminish, usually about 500. So if you leave it plugged in you can reduce your battery life span considerably - otherwise it should last a good year and a half before it wears out.
Dont ever try to trickle charge, overcharge or manually discharge a lipoly battery as they have a tendancy to explode.
The good news is lipoly batteries are cheap to manufacture. You should be able to pick up a decent bst-38 (or substitute) on ebay/amazon for around 15-20 euros. Dont be hoodwinked into the 2000mAh batteries, most are fake. My 970mAh can last 2 days on Gintonic rom.

I had a similar problem with the battery discharging whilst charging.
For me the problem turned out to be my USB cable becoming faulty. It would still transfer data when connected to a computer, but would get a similar problem to the one you describe when charging. Might not be the same problem for you though.
I am now experiencing this problem. I think it is my usb cable too. Will buy another 1 soon. It discharges then charges again when I pull out the cable and plug it in again.

Well already tried wiping battery stats
heres what I've discovered till now
-The charge current drops as if the battery is at 91% but it isnt even close
-It is either the battery is sending wrong data to charger, or it is faulty
-Not able to explain how n why it discharges even a switched off state???
-Only solution I can think is a charging dock for BST-38

If I leave my cell on charging for 8 hours, then after 8 hours my battery will be zero... It'll keep blinking the red light for hour or more... See thats a wicked problem...
happened to me also, had to use a better cable (don't use thin and/or long cables)
Yeah I tried with a Nokia made cable and its charging flawlessly! This is my first time with a Non-Nokia n so far the experience is not very good!
btw thanxxx a lot for your attention n concern!
- similar (identical) problem, tried similar resolutions (factory reset/sdcard/sim removing/different chargers/battery replacement)
- disassemble my phone... and found out, that micro usb connector replacement is unrealistic.
- watched charge/discharge/voltage/current/temperature process trough battery monitor widget (1 minute sampling)..
- re-calibrated battery many times
RESOLUTION : micro usb connector or connections in mobo is dead. I build charger with current meter. No matter, what says my phone about charging (pluged in - discharging)- any information displayed delays for minutes on phone. IF my external current meter says - "charging", than phone state is "CHARGING" independent from what phone is displaying at the moment. Moving usb charging connector in phone causes current to stop flying to phone or reducing current value. Phone still says "plugged in" and or "charging" on "discharging"...
Temporary resolution: little pushing/deformation on charging connector (male) and LED in charging chain, witch is displaying - charging or not. Every time connecting charger i'm looking on indicator LED and moving charge connector, till LED says "charging" and then no more any moves on phone.
Future resolution: contact-less charging trough inductive coupling
Yes it sounds like a catch-22 and that's exactly what I think it is.
Yesterday my phone battery bailed on me. So I plug it in for a night and wake up to see it hasn't charged at all. It's still off and continually displaying the battery charging icon, after which it shows the Samsung Galaxy S2 logo, after which it dies. This goes on forever.
I've tried different outlets, also my computer's USB port, but to no avail. I have the impression that it wants to be on to charge, and since it does not have enough power to start, it won't charge. Seems like the amount of power from the charger suddenly isn't enough to start, or that the device tries to start before the battery can handle it.
This evening, after not trying anything for an entire day, I got it to show the CyanogenMod logo, but it got stuck on loading. So I took it out, wanted to go into the CWM to wipe some settings and have a clean installation, but then it bailed on me again.
Now I'm back in the endless charge-start-die loop. What can I do?
Hi,
I think your battery is messed up, buy a new battery. Or make it go into recovery mode. Or, go to your nearest Samsung Centre.

Do you have a multimeter to check the voltage of the battery?
Either you will need another phone that will accept the battery to charge it or your can charge the battery externally with a lithium charger (think Remote Control cars, planes, helis)
or ebay for a new battery.

BTW Lithium batteries will die very quickly i not kept above the correct voltage. Li-Ion are charged in two stages. Constant current, and then constant voltage.
Constant current is to apply 500ma at around 3.7 or 4 volts per cell till the battery voltage gets to its upper limit depending on what battery chemistry you have. Then keeping the voltage at that limit, reduce the current continually till the battery is fully charged. As I do not know the max voltage for the cell, I will just assume that 3.5v will be a safe amount.
So to charge, simply apply 3.5 volts to the phone battery for a few minutes at a time, with a resistor or light bulb in between so the current is limited, then checking it back in your phone inbetween to see if it charges.
If you are confused at the major concepts here then just buy a new battery, to save breaking you or your phone.
I'm travelling around in Asia but the local market had a place that had proper equipment. I managed to fix the battery by charging it with an external one-fits-all charger (where you can put the positive and negative leads anywhere). After that I can just use the phone again and charge it normally.
If the phone didn't try to start but would just charge the battery when plugged into the mains, this would also have worked. Anyway, I had a new battery made (I'm in China so they just pack a random battery with some rubber to make the size fit into some stickers and that works). Funny thing is, it has 1900mAh, a lot more than the original battery, though being a lot smaller in size. I hope it will last...
thanks for the tips
Hi guys,
i have the same trouble of him, and i can share you that my wife and me just bought two galaxy s2 white from France...they are totally new (two weeks ago).
Here the bug i confirm, if we are out of battery, then to plug it in the official craddle of my car, with the official charger will power on automatically the phone, then it will loop in on---off--on--of, because not enough power to keep the phone charging.
I confirm that the only way to make the phone charging correctly is to plug it with the power socekt wall charger, by the car there is no way.
It seems the difference between the car charging and the house charging is that in the car when it is plugged the phone power on auto, in the house the phone charge without powering on the phone....
Is there a way to force in the car with the craddle to charge some minutes without the need to power on it auto ??
Your battery is not dead, or in France my wife and me got the similar issue and it is really not possilbe...
Hi,
have you tried to remove the battery from the phone for at least a couple of hours and then put the battery again and plug it?. I had the same issue and doing this I could charge the phone after a couple of tries. I hope you got luck with this.
I've tried it but it wouldn't work. A separate charger (charge outside the phone) did the trick, no more problems since then.

1 Cell lithium batteries like phone batteries are nominally 3.7v but their voltage depends on charge. They should generally be charged to a maximum of 4.2V, and not discharged below 3.3V/3V, depending on who you ask. You don't want to get it wrong though - look up what happens if you overcharge a lithium battery on youtube!
Same Problem Battery Logo Boot Loop
Has this problem been solved ?
I have the same Battery Logo Boot Loop
I have several batteries, and a separate charger ... batteries at 100%
The problem occurred while phone was in use, connected to wall charger, and had reached 100% .
I continued to use the phone while plugged into charger.
Phone shut down with a Battery Logo showing only a thin green line at bottom.
I turned phone off and swapped in a hot battery, but phone would not turn on.
Stays totally black screen, will not enter Download mode or Recovery mode.
With charger plugged in it will go into the Battery Logo Boot Loop.
The blue light next to the power button flashes, the Battery Logo appears for a few seconds then screen goes black and cycle repeats.
Any help will be appreciated.
Thanks

Hi all i have a problem with my sgs2 i don't know if it is the battery the charger , Apps or charging port. When the battery gauge shows 1% i can't charge my phone it stops to 2% when i plug to usb it can't connect as mass storage properly and when even the phone shows full charge then i unplug it battery gauge falls suddenly to 60% as an example i have try changing two usb cables same issue plz help
hi guys, just wanted to share a very handy device i have come across that i really like. I have an extra battery and cradle, however i dont trust the charging capabilities of the cradle once it reaches full charge. I know the device itself will slow down and trickle charge once it reaches full capacity, but in the cradle im afraid of overcharging the battery. anyhow, i began looking for a timing device to prevent this. I came across this item
http://www.amazon.com/Belkin-Conser...=1421085461&sr=1-1&keywords=belkin+timer+plug
it has a half hour setting, a 3 hour setting, or a 6 hour setting. i began to find myself using this, not only for the cradle, but when i go to bed at night. i connect it to my phone. 3 hour charge, then it shuts off. im surprised these arent more prevalent. in fact, belkin was the only one i could find, (short of those xmas light dial timers lol). let me know what you think
I've been using the cradle and extra battery for a while now. No issues. I swap it out daily(well until I got my PMA sticker)
Even before then, I noticed no issue with poor battery performance or life.
Here's some helpful info from Battery University website:
Simple Guidelines for Charging Lithium-based Batteries
A portable device should be turned off while charging. This allows the battery to reach the threshold voltage unhindered and reflects the correct saturation current responsible to terminate the charge. A parasitic load confuses the charger.
Charge at a moderate temperature. Do not charge below freezing.
Lithium-ion does not need to be fully charged; a partial charge is better.
Chargers use different methods for “ready” indication. The light signal may not always indicate a full charge.
Discontinue using charger and/or battery if the battery gets excessively warm.
Before prolonged storage, apply some charge to bring the pack to about half charge.
Over-discharged batteries can be “boosted” to life again. Discard pack if the voltage does not rise to a normal level within a minute while on boost.
