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
Just notice this, just now i see this screen when charging with phone turned off. I try 2/3 different charger from other manufacture still the same, but all charger works when phone On. Any solutions will help. Thanks.

That indicator means the Streak isn't recognizing the cable, so you have one of two possible causes here:
1. The cable is bad
2. The port is dirty or bad
To properly troubleshoot, clean the port with a cotton swab and rubbing alcohol. Let the port dry, which should only take a couple minutes or so. Then plug the cable into the port. If it still doesn't work, try another cable. If it still doesn't work after that, the port is likely your culprit.
will try. thanks.
edit ; but, just found that if connected to the computer when screen off, it's charging properly. So this is maybe charger incompatible issue ? i don't have original Dell Charger, so from the day i hold this lovely device i use random wall charger adapter from my blackberry, LG and iPhone.
Sent from my Amazon Kindle Fire using Tapatalk 2
you know.. it is quite bad to mix use of wall charger.. since it would affect your battery... try to use just one charger and stick to it... i use samsung galaxy tab original charger with rating 5V 2A by the way...
Ya i think u right. 1 more question if you don't mind, sometimes... i just need to 2-3 hours to perform full charged. But somestimes ( usually in some miui ROM ) i need more time like 4-6 hours to full charged. Whats that ? I try using Battery-Calibrating apps from market or manually deleted batterystat file, its result randomly, sometimes working, sometimes not. Can you please explains more about battery... thanks.
Sent from my Amazon Kindle Fire using Tapatalk 2
usually when we flash rom over another, the previous battery stats would be used... so doing a recalibration would help to get back the actual battery stats...
so.. when you notice the charge length is not correct or it is not like usual... doing recalibration would help..
charge half way... or you charge and then forgot bout it until the next day... something like that would affect the battery stats also...
if you maintain the charge cycle appropriately .. it would help the battery stats maintain the correct value too...
i also sometimes forgot bout the battery.. i mean we charge the battery and then goto sleep... if the charge is only 3 hours but we sleep more than 6 hours the different of 3 hours there would make a difference to the battery stats... where the stats would start to get hayway ..
yes, i do flashing frequently, i quickly got boring with just one rom
and yes, i charge my phone before sleep almost everyday, is that bad ?
right now (with miui rom) for example : when battery indicator show 39% after charhing 4 hours more, disconnect cable, i turn it off, i enter recovery (this weird, it boot in recovery, as i know, we only can enter recovery if we have above 50/60% battery, right?) so i wipe batterystat and reboot... voila.... its show 75% ???
how come ?
in some calibration apps say :
" Its not necessary but recommended to use phone until it shutdown it self, and recharge without a break start with phone off"
since i can't charge with phone off because of my incompatible wall charger adapter, so i never complete this above step. is it really needed to be done?

This is only partly correct.
The battery would be affected if the output voltage of a replacement charger was different from the stock charger, although it is more likely that the Streak's circuit board would blow a component or two. However, the battery will not be affected by the output amperage of a replacement charger. The only thing that will happen is the amount of time it takes to charge the battery will increase or decrease depending upon the amperage the adapter puts out.
For example, 4.0V, 2A is a bad thing. 6.0V, 2A is definitely a bad thing. Both can do damage to the battery because the voltage is what has changed. However, 5V 1A or 5V 3A won't hurt the battery at all since the only thing that changes is the amperage. As added protection against damage and/or battery explosions, there is a voltage control circuit inside the battery that not only monitors the individual cells that make up the battery but also can measure the incoming voltage. If the voltage is too low or too high, the battery will cut the charge circuit and prevent an explosion. The circuit doesn't measure the amperage because it doesn't need to, and thus the battery will happily charge at both lower and higher amperage than recommended without damage.

thanks for explaining, so its okay right if i use 5.0V 700mA ?
Sent from my Amazon Kindle Fire using Tapatalk 2
It will work, but it will take longer to charge as it's only 700ma versus the Streak's 1A. The charger may become slightly warmer as it has to work longer, but otherwise you should be fine. Had the difference been greater, say using a 500ma charger when a 2A was required, you might damage the charger, but not the battery.
okay thanks, now i know how to charge my battery

Today I took my DNA for a spin using google maps. And to power the beast I used a 2000mA momax charger. To my surprise halfway through the trip I noticed my battery level had halved. I remember seeing the charging icon on the battery so thought ok its charging it.
But when we arrived after a 45 mintue drive i lost over 50% battery It seemed it wasn't charging after all. The phone was extremely hot
Did it get too hot possibly while driving and stop the battery from charging as a thermal safe guard from overheating? I'm on the stock kernel. Anyone had this issues like this? And does anyone know the MA rating of the official DNA charger? I'm in New Zealand so i cant just pick up the official charger or anything like that.
If i cant use the GPS without the phone charging it will make it unuseable on long trips
Edit: Problem found, phones gets too hot on the dash and running GPS it will throttle and not allow the battery to charge. Thumbs down to HTC making a phone with GPS that can't be used for more than 20 minutes or your phone overheats.

the rating on the HTC charger is 1000mah.. one thing i have noticed that some higher MAH chargers will actually cause the phone to charge in "USB" mode.. when you plug that charger in check the battery settings screen and at the top it should say charging AC or USB.. if it says USB then that is likely your problem since USB charging mode is much slower than AC charging mode.
Awesome tip. Never knew that, thanks!
Wow thanks very useful info indeed. I think i might be over doing it and making it overheat. I will try a 1000mAh charger in a few days and see if that solves the issues!
So the problem doesn't lie with the actual mA output of the charger, but with the way the charger is physically pinned out. On "fast" chargers, that is, chargers that can deliver more than 500mA of current, the center two data pins, D+ and D- are shorted. This short tells the phone that it's plugged into a dummy charger and allows it to draw more current (I believe the DNA can draw a max of 1 amp when in AC or fast charge mode). In a computer USB port, these two pins obviously aren't shorted as they are the data pins. Without the short being present, the phone assumes it is plugged into a computer where USB 2.0 specifications allow for a maximum of 500mA of current draw, so the phone software limits the charging rate to 500mA. The flaw in many aftermarket chargers, even the super high power ones, is they omit shorting the center two pins, resulting in the phone only allowing 500mA of current draw. This is a problem with both car chargers and some home chargers, especially the multi-port chargers designed for iPads and smartphones. Apple uses a different pinout for their high speed charging that isn't as simple as shorting the two data pins, so many Apple branded or "compatible" chargers don't put Android devices into fast charge mode.
For a car charger, my personal favorite is this Motorola one from Amazon. It provides up to 950mA of current, is genuine Motorola OEM so it's built well, and best of all is only $5 with free shipping if you have Amazon Prime. The only drawback is the LED is kinda bright and annoying, but I keep it in the outlet inside the center console so I never see it. http://www.amazon.com/Motorola-Vehicle-Adapter-micro-USB-Charger/dp/B000S5Q9CA/ref=sr_1_1?s=wireless&ie=UTF8&qid=1356666975&sr=1-1&keywords=spn5400
Yeah I use that charger too. Works well. I recently bought a dual USB output one that claims it puts out 1amp..but my phone shows USB mode. Is it only putting out 500 then?

Your phone is only drawing 500... I have a qmadix 2 amp micro usb with an extra usb port and it puts out plenty of power to charge 2 phones while using gps and listening to music.

Thanks for the info, still not luck for me. I brought a brand name 1 amp charger and used it again. It charges well to begin with. But after about 10 minutes the notification LED in the phone will start to flash .... Then it seems my DNA is not charging at all. Status bar tells me in the beginning it was not on USB charge. After the 10 minutes no charging detected at all. Its as if the droid disables charging.
I will check the cable too again and see if that was the issue. It might be the charger and or cable. But the first charger charged my Note II without any issues and fast. It never lost battery %
And again my DNA was scorching hot. Which seems to me more of an a throttling thermal issue. Its reaches xx temp and charging is disabled. Does the flashing led mean something? It was a sunny day and its summer here in New Zealand so the droid just got too hot maybe? Being black on the car dash in the sun cant help it.
I love this phone, and have my note II up for sale but if i cant fix this issue it seems GPS and Nav is a no go for me. Which is not good. I travel a lot.
Update,
I did some further testing and the news is bad I used my standard HTC DNA charger, and tried to repeat the conditions. Got my phone hot and low and behold. On the charger it will stop charging once the phone gets too hot. It will flash a green light, then orange, and repeat.
in other words if you want to use this phone in summer on your dash as a GPS you might want to think about running the A/C on it at all times
Can other please test this? Maybe i just have a faulty CPU, but i think its a built in thermal safetly feature once the CPU gets too hot it will not allow you to charge it. So in other words if you want to use this phone in summer with sunlight on your dash as a Nav/GPS think again ;(

This sounds right to me. My last 2 devices had the exact same issue when heating up. I do believe that fast charging really heats up the battery, so once it hits a threshold, it stops drawing power in order to cool off. Don't want a battery exploding in your phone.
The GPS radio can sometimes draw a bit of power, though it is much less on newer phones.
I digress, I really do think that in most cases, heat is the issue.
Its a very sad state of affairs, I cant use this phone as satnav / GPS without loosing a lot of battery life. Seems its only good for winter GPS when used on the dash in the sun of summer it will just over heat and not charge. Very poor if you ask me.

Try testing your phone at 'room temperature' (75 F, 30C), if your phone overheats using the GPS in this case, then you should return the phone because it is not normal.
If it is overheating on a hot dash board, ALL of my phones have done that. You can try blasting the wind shield vents to counteract the heat.
The DNA is normally great, but either your expectations are a tad unrealistic or your phone needs to be swapped.
A solution would be to mount it in a way that isn't in direct sunlight, like using one of those vent-mounted adapters. Then if it got hot, you could put the air on and it would cool it down.
Another option would be to either turn the brightness down, or to completely turn off the display, unless of course you have no idea where you are, and need more than just the audible directions.
But really, it sounds to me like your specific phone is just prone to overheating, and needs to go back. I haven't had any temperature-related functional issues at all.
Sure, it's gotten warm. But it's never failed me as a result of being too hot.

Well its summer here and its not taking the suns heat and being black doesn't help. I will see if I can move its position or place it over the A/c vent of the windscreen.
Wait till summer in the U.S and you will see more threads like these i think. I only comment its poor because no other phone of mine has done this in the past. Maybe mine is faulty.
Used mine for over three hours (one-way) using GPS/Maps full blown with no trouble or heat at all. I was also texting, surfing, playing games and talking on the phone at various times and had to plug in after awhile using the usual car charger. I don't like to get below 50% if I don't have to. Anyway, no trouble on the way there and no trouble on the way back.
HTC has always had the best gps radios I've ever used. My wife's GS3 still can't get as good, fast, and pinpoint lock as my DNA (or my Rezound for that matter).
As always, YMMV.
No offense man, but who the hell leaves their phone in the sun and expects it not to overheat? haven't you ever left your phone in the car in the summer and come back to a red triangle or a high temperature sign?
The key to keeping your electronics alive is to keep them cool. Your phone is just like your computer...you try to keep the temperatures as low as possible at all times.
I have a generic cigarette lighter adapter I got off ebay. I used my the google gps on my phone to a store in CT for the wife and then a trip to Boston, well over 3 hours worth of continued GPS use. When I unplugged the phone when we parked in the garage I had a full battery and the phone didn't appear to be any warmer than playing a regular game.

That's how every phone works. If you are using it in a hot environment and in direct sunlight it will try to cool itself down by stopping charging.

Sorry bud, you cannot expect to leave your phone on the dash in direct sun, while using GPS AND charging and not have less than optimum results. You are KILLING the efficiency of your battery by allowing it to overheat continuously. Keep it cool man!
People will find anything to complain about...
I have an Infinix Note 2 (X600)that have some charging issues
when i charge the phone i usually need to jiggle the cable a little bit to get the power flowing, but lately it gets much worse. when charging my phone need a lot of time to charge. The charger is not the original phone charger, it's a spare samsung charger i found lying around in the house. its usually works fine up until now. I checked the charging power in ampere app and i found that the charger lose charging power slowly over time. for example the initial charge rate is 900ma , the charge rate slowly decaying -10ma /5-10 second to a point where the charge rate hit 0ma. i could leave the phone overnight but instead of charging the phone it reduce the phone battery instead.
My initial thought that it's because the faulty charging port because i game while charging and janked it fairly often. and ideas of what causes my problem or a fix ?
second question: is charging ports of micro usb android is all the same ? or it's different per phone model, cus im thinking to get the port replaced
Long story short. Use the manufacturer recommend,if not the original.
Yes they will mostly work, but when you take the cost of the device into account....
There should be information on this within the website for the smartphone etc.
Ironically enough, my battery died while I was typing this and I was running a GSAM bat test using always the original charger.
In logics term's, you can always start a car with a much cheaper battery, but when you're taking into account of longevity over quality and anything else you can throw at it, all roads have intersections...
Please email the manufacturer, things not the 90s so you will get better support [emoji12]

Hello, My phone problem is, whenever i charged my phone to any certain percentage like 80%, 90%, 100%, and unplugged the charger and using the phone, first 5-10 minutes its consume 5-6% battery and first 1 hour of using its consume 10-12%.
This problem happening to all roms including stock rom
So it's not your 'roms'.
Tell me about your fone, how old, and what type of battery?
Does the fone heat up at all when it's draining?
Is there an extra slight BULGE at the back of fone?
I know some charger's, like the iphone chargers, can and do lose their amperage, it's how they sell more charger's, by providing the volts but not the required amps, or in this case, milliamps.
Let me know, and I'll try to help quick as

no heat up while charging and discharging
cant sure is the phone slight BULGE at the back of fone?
By bulge, I mean, does it feel slightly fatter? Bigger? Swollen? can you take battery out, if so, is it neat and tidy, as in, lay battery on a flat surface, it should be flush with where you place it. If it's flat, turn it over, is it still flat?
Have you had any recent updates?

no its not slightly fatter and my phone has glass back panel.....yeah got new updates,but the problem is on every roms
but some custom kernel like etherious and agni kernel...the battery draining normally
So if your battery was getting fat, it would be time to replace it, but due to glass back, you cant tell.
Do you standard charge, or turbo charge?
Back in the 80's, I learnt a fantastic trick, read:
Batteries develop 'memory'. They remember how long they were charged for, in that they kind of copy the previous charge, and dont go further than where the previous charge was halted. Meaning if I'm in a hurry, and pull out fone at 60% charge, next time I plug it in, it MAY see the 60% previously disconnected, as full charge.
For instance, I buy a new battery, when I get it, I dont know how long it sat on the shelf for, as it's charge slowly dissapaited through non-use (yes this happens) while sitting on shelf. So when I get the battery, the first thing I do, is place an electrolytic capacitor (valued around double the voltage of the battery) and place negative of capacitor to negative and positive to positive on battery, the idea being to drain it completely. Once I get no power from battery, I then charge it for 24 hours.
This erases the 'memory' the battery develop's, making it like new from factory. The above is the 80's version of recycling a car battery. But you cant drain the battery, being sealed in your f'n, so try the following:
Grab a usb adapter, say a 4 port (mines a 7 port), and plug your powered on f'n into it, whilst filling the other ports with any other usb devices, the more power they need, the quicker you drain your fone., being the objective.
Do not plug the usb port itself into ANYTHING, and do NOT apply power to the hub.
Leave until nothing lights up plugged into the hub (have a thingy with lights plugged in to see the power drain).
Look for a 3.5mA usb charger, the type used for tablets, the amazon fire tablets charger is ideal for this. Once you have completely drained battery and know nothing else works cause your fone cant supply the other devices any power, plug your f'n into the 3.5 mA (milli-amp) charger, and charge for 48 hours.
This is the electronics engineering method of renewing a battery.
My scource is an old '80's magazine, co-incidently, I'm in same edition called CB magazine, the first ever printed version of how to make a battery like new. I hope this works, cause I dont know the actual fone, but if you do this, you'll have the added advantage of knowing you just 'made' a new battery, and learnt not to buy sealed fones where you cant release the battery to swap it.
As I say, if it's a hardware problem, you'll know after this.
Edit: I know apple mess with the charging cycle to make people buy new iphones, which they do in updates. Your problem MAY actually be this.
Good luck!

So if your battery was getting fat, it would be time to replace it, but due to glass back, you cant tell.
Do you standard charge, or turbo charge?
Back in the 80's, I learnt a fantastic trick, read:
Batteries develop 'memory'. They remember how long they were charged for, in that they kind of copy the previous charge, and dont go further than where the previous charge was halted. Meaning if I'm in a hurry, and pull out fone at 60% charge, next time I plug it in, it MAY see the 60% previously disconnected, as full charge.
For instance, I buy a new battery, when I get it, I dont know how long it sat on the shelf for, as it's charge slowly dissapaited through non-use (yes this happens) while sitting on shelf. So when I get the battery, the first thing I do, is place an electrolytic capacitor (valued around double the voltage of the battery) and place negative of capacitor to negative and positive to positive on battery, the idea being to drain it completely. Once I get no power from battery, I then charge it for 24 hours.
This erases the 'memory' the battery develop's, making it like new from factory. The above is the 80's version of recycling a car battery. But you cant drain the battery, being sealed in your f'n, so try the following:
Grab a usb adapter, say a 4 port (mines a 7 port), and plug your powered on f'n into it, whilst filling the other ports with any other usb devices, the more power they need, the quicker you drain your fone., being the objective.
Do not plug the usb port itself into ANYTHING, and do NOT apply power to the hub.
Leave until nothing lights up plugged into the hub (have a thingy with lights plugged in to see the power drain).
Look for a 3.5mA usb charger, the type used for tablets, the amazon fire tablets charger is ideal for this. Once you have completely drained battery and know nothing else works cause your fone cant supply the other devices any power, plug your f'n into the 3.5 mA (milli-amp) charger, and charge for 48 hours.

So in short You tell me to do that is, i have to connect a usb hub to my phone and discharging all the battery. then i have to charge my phone at least 48 hours/2 days?
Yup. If you take your time, and it's not hardware or update related, you'll be glad you did. At the very least, you make your battery brand new for sure.
Whilst googling, I found some saying some optimisation service wont stop, but hey, it's now down to you to help yourself

don't take me wrong......so the methods u told, really improved li-ion batteries..
and also i dont have any 3.5 ma charger....can i charge my phone on pc usb port
and when charging 48 hours, do i have to turn on the phone or charging with switched off

Yeah it works with EVERY battery made by man, unless it really is DEAD, like no acid to react to the li-ion, shame we cant add water like the car batteries of that time to prolong the battery life lol, back then was poor days, lots of handy finds were found...
I would not recommend the pc/laptop method, because I'm pretty sure those usb ports only provide 50 ma (a quarter of 2.0 mA, note the small ma compared with the 2.0 mA)
Power to pc/laptop end user style is 2.0mA devided by amount of ports.
Any single charger rated 2.5mA or above is what you want, so I use 3.5 mA.
Check old big phone chargers, look at the plug, go for more power than your actual fone charger, which I must ask, is rated at how many mA? I predict 2000ma (2.0mA)
The time (2 days) is to FORCE more power into the previous 'rememberd' memory, literally blowing it's mind lol. After this, you use your standard charger, this is only to fix BATTERY, so then we know if it's hardware or software, cause you did the work and patted yourself on the back lol
Edit: keep fone off while charging, just use another old one or borrow one till the charge is complete. By cheating you only cheat yourself lol. By doing, you WIN.

my phone charger is 18watt fast charger....than how many ma it has....and how many watts in 3.5ma charger??
Glad you asked. Your charger is a 2.3 AMP or 2.300mA like I said, try a larger charger
Look at charger till you get what I'm saying re: ma, mA or Amps (A)
2.0 AMP is 2000mA
To make it easy for you. 2.0 ma (how it's sometimes written) is = to 2000mA or 2.0 AMPS, but do NOT make the mistake of using 2000 AMPS lol, I'll hear you from here...
Electronics is defo not software and I forget sometimes i'm dealing in milliamps and amps, etc rather than megawatss from my radios lol
So you will look for a plug that MAY show EITHER 2000mA or or 2.0 AMPS. The old way to write milliamps were once similar, so ma was made mA to show amps. Keep my age in mind lol
