Anyone using this battery charging case? Bought one from Amazon a week ago, it works great but there is one problem.
As we know when just charge the phone using any USB C cable. I usually charge it at night when I goto bed, so when it charges the phone up to 100% full and the phone will remain 100% unless I unplug the charger (doesn't matter how many hours or days)
But if I put the Alpatronix battery case on my phone, when I charge it all together (according to the manual , it was programmed to charge my galaxy s8 first then battery case) When my phone reaches 100% it stopped charging and I can see the battery starts draining even though my charge cable still connected. This is what I don't understand. I tested it with straight charging cable and wireless charging. Both end up the same with the Battery case attached. It will charge my phone and the battery case for sure, but it stops charging while my phone reaches 100%. And when it starts draining from 100 to 99 and so on. It will not automatically charge my phone itself till it is full. It will only charge the phone when I am not using battery case. My phone will remain 100% all the time with charge cable connected. No matter how long I have the phone connected to the charger, hrs, days. It will keep it 100%. I wonder what is the main problem? Would it be a defective Alpatronix battery case?
I think it is normal?
I've had many kind of power bank, which is the same principle as battery case. Most of them stopped charging when phone battery is full, and yes, you need to initiate the charging again if the phone battery starts decreasing (usually by pressing the button).
Well, there are several "smart" power banks that starts charging when you plug in the phone, and does trickle charging when the phone is full. But, what I want to say is that not every power bank is made of the same system.

Are you talking about power bank or battery case?
If you know any battery case that has the feature I mentioned above, can you give me the name?
I have a few power banks but I don't like carry it separately. Battery case is more convenient.

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.
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
Guys I bought one Samsung Extended battery kit (2000mHa - genuine) last week and it worked a charm, noticed a considerable increase in battery life when compared to the stock battery 1650mha.
However on the weekend my Galaxy ran flat and now charging the phone, the phone starts charging, boots up, Samsung flash screen appears, then loads the main screen, stays there for 5 - 10 seconds, then phone powers down and turns off
I have tried several chargers, Blackberry (700ma) and the original Galaxy charger (USA charger - I live in Australia). I have read a few reviews that suggests I may need a higher output charger, maybe a 800ma or 1000ma charger? Would this be correct?
If the phone is still got charger, say 30% battery remaining, and I charge it using a Blackberry or Samsung charger, the phone charges fine, if its completely flat, it won't charge at all.
The phone has not been rooted and I am also running the 2000mHa extended battery mentioned in this post.
Any ideas to why the phone boots up, stays on for 5 seconds and turns off?
Info on charging rates for batteries:
--------------------------------------------------------------------------------
Li-Po (cell phone, RC car) batteries are pretty unstable when compared to NiMh/NiCd (AAs, reg Automobile) batteries.
When Li-Po's first started coming into the Remote Control Car Hobby, the big thing I was told to watch out for, and follow to a T was the charging and discharging rates, because if you neglected them, that's when the cells would swell and possibly burst into flames.
Rule of thumb is never charge at more than a 1C rate or exceed the batteries voltage, meaning if it's a 2000mAh battery, don't charge at more than 2.0A, if it's a 1750mAh battery, no more than 1.75A, and if it is a 1355mAh battery, no more than 1.355A and so on and so on.
For our stock, single cell(3.7V) Li-Po 1850mAh battery, the perfect, ideal charge rate would be no higher than 1.85A at 3.7V.
It blows me away that the stock charger is 5.0V, but Samsung obviously approved it so...Whatever.
I can almost guarantee you that our phones would never discharge at more than the batteries max rating.
To sum this up - don't charge it at more than 1.85A and 5.0 Volts and you should be fine. If you can use a charger with les voltage than 5.0V, I would use that one...

One its a question in the wrong forum .
When flat does it not charge with phone powered off as normal charging practice for a dead phone .
jje
I have noticed this.
My theory is the phone does not charge while booting. So what little charge you had put in, would only be enough to boot, then by the time it can fully boot to charge again, it doesn't have enough power to stay up so it boots off.
If you left the charger on with the phone off for 10 min, should have enough to power up and stay powered. Try that.
Ive haad a zero lemon 7000 may battery for months now for my s3, however recently when I plug my phone in to charge, it charges until its full and then I take out the charger, plug it back in in 10 seconds and it charges for up to 3 hours and does the same thing again

i didn't quite get your point but if you are saying that the phone takes a lot of time to charge
like way more than it should try a different charger and see if the problem is still there
Or check the spring contacts in the housing. Maybe an after sales or not original Battery has squeezed the contacts

No what I was asking was, when I plug in my battery, I let it fully charge until my phone says its charged, then I unplug it, wait for 5 seconds plug it back in and it starts charging again for 30 minutes and it Keeps doing the same thing everytime I unplug it and plug it back in
This was how people thought they were "calibrating" their battery. Forcing "juice" into it. Its not healthy. Stop doing it

^^ What he said...
PLUS, let the battery drain until it is below 10%. Fully charge it (the FIRST time) then let it drain again to under 10%. Take out battery and hold down power for 30 secs then put battery back in and charge it up without turning it on. When full turn it on and see how it goes.
Most if not all modern batteries NEED regular drain to low figures to keep them healthy. Failing to do so causes issues. Also to protect th battery, the software cuts the charge out BEFORE the battery is absolutely 100% charged. Taking it to maximum charge like you have been doing will kill your battery quickly. The software will protect the battery if you charge it up and don't unplug when it gets to 'Charged' but when you unplug it then plug it in again it tries for a new charge - bad for the battery.
