This has been a somewhat recurring problem since I got my phone. Some nights when I put it on the charger the battery icon will show that it is charging, but when I wake up it will be at 30%. I have to take the battery out several times before it actually charges. It did this a few nights when I first got it, but then it got better for the next couple months and now it's doing it again. I'm running CM7 with Da_G's kernel and haven't changed anything since the first successful flash. I'm also using the same battery and charger that came in the box.
I noticed that the battery is rated 1850 mAh and the sticker on the inside cover of my phone is rated for 1500 mAh, would that be a problem?
Maybe you just have a junk Battery? I would try another one. (and that way at a minimum, you have a spare)

Try this: go to your dialer and dial *#*#4636#*#* and tap battery information. There's a couple things to look at on this screen, first of which would be battery health. If it says anything other than good, try resetting your phone. If it says good, then plug in your charger and look at the battery status field. It should say charging. If it says discharging, try a different charger. If it's still discharging on a different charger, do a master reset and try again. If it still discharges after the master reset, you should look at getting your phone replaced.
It says the battery is in good health and that it's charging, but it's been stuck on 29% for about 30 minutes now. I'm thoroughly confused.
Did you try a different charger?
Sent from my SAMSUNG-SGH-I727 using XDA
If you tried a different charger and the factory reset didn't make a difference you should look at replacement.
Yup, try a different charger. Samsung oem usb cables have had some issues.
And if that's the case you should get a free replacement from AT&T. And get a replacement battery while you're at it, always good to have a spare...

I used my charger from my old phone and also my car charger and it just seems to be random when the battery decides to charge. There's no definite way to get it to charge, I just have to plug it in and hope for the best and maybe do a few battery pulls. Sounds like I'll have to buy a new battery.
Don't buy one, that's a warranty replacement. And if that doesn't work get a replacement device. Something is defective.

Talking with support now, thanks for the heads up.
I had the same problem this morning. I am on ICS 7.4 stock and I recently added some mods from dark kobalt theme. First my phone died while charging, so I turned it back on and I received a message about too many things running and before I could stop the tasks it turned off again. After a couple tries, I was able to close all background data etc. At this point it still wouldnt take a charge but it would stay on while plugged into charger...15 mins later it started charging normally again!

I've noticed that the battery meter will sometimes stay at 100% for a while and then all of the sudden drop to the actual percentage sometime later. A reboot after unplugging the phone will fix the problem and report the battery % at the correct level. I was wondering how many other people were experiencing this, or if it is just a hit or miss thing?
I'm still on stock, unrooted, no mods. It's a straight out of the box Skyrocket.
Also, does the problem remain after rooting, modding, etc.?
I asked this on the battery results thread in general, and only received one response, so I figured this would be better in Q&A.
I had the same issue, but it has only happened one or two times.
Showed 100% for hours then rebooted and it showed 73%
I don't know how long you've had your phone, but it takes several cycles from full to empty for the battery to calibrate correctly. During that time you can get some really funky readings on it.
I am experiencing the same problem.
I've also had a hard time charging the phone. I've left it plugged in upwards of 18 hours, only to find it saying its only 83% charged. That may just be another symptom of the same problem though.
Do you think this is a phone or a battery issue?

That sounds like you were plugged into a pc vs ac power and had heavy usage during that time.
Mine charges very quickly when at idle and plugged into the wall.
I've had my phone since the day it launched (the 6th) and just experienced this for the first time yesterday. It was indeed quite odd to see.
I have had this happen one time. I also noticed the phone got very hot.
It actually happend yesterday, stayed at 100% almost all day then just shut off and wouldnt reboot.... freaked me out!!

I think that the battery is pretty wonky. I am not sure if the NFC addition is causing these issues but some people are having amazing life ans some people (me included) get horrible. I am getting a warranty exchange on my battery. No way I should drop 12% in an hour and 20 minutes when the only usage is 19 minutes of checking email. If I have to have it plugged in every time I turn around it is not exactly a wireless device now is it?

Strange, I was just reading this thread and thinking I have never experienced this. Then I checked my battery stat and it showed 100% even though I've been using it for an hour and a half. I restarted and now reads 90%.
Had my phone for almost a month. Rooted only on stock ROM. Just took it off USB cable from laptop an hour and a half ago.

I think we narrowed it down to being a bad charging circuit in the phone or battery triggered by a .1a charger.

I was powering my phone off, plugging the power in and allowing it to recharge. The phone would automatically power on as soon as I connected the power but I didn't think that mattered. It turns out it did. If I powered the phone on and then connected the power, the battery meter would work correctly.
This was different the Captivate I had previously. That phone had the capability to charge while powered off. There was even a charging graphic that displayed while the phone was off.
The Skyrocket did not have this same feature when I originally bought it. However, ATT did an update at some point and now it does. I've been unable to re-create the stuck battery gauge since that update.
please only use the charger that came with the phone. other chargers, after prolonged usage, may cause issues.
The charger that came with most skyrockets is a .1a charger and causes the issue as well. A few reported getting .7a chargers in the box but most have been .1
I have tested the iPhone charger theory on 5 phones now. Phone 1 and 2 experienced the issue. Phones 3-5 did not
Its more than just the charger. The phones experiencing this either have a bad battery or it's in the phone

From day 1 with the skyrocket, I have used an old wall charger and cable and had this problem daily. I plug it in at night and in the morning, it's at 100% until I reboot, or some other random event that drops the percentage to the real battery stats.
Because of this thread, I dug out the box and used the wall charger and cable that came with it, and this morning shortly after unplugging the phone, it was at 99% and dropping, just as it should. Very glad I tried this.
Ummm no.....

I did a recheck of my black cube SR wall charger (Samsung part # ETA0U80JBE).. It is NOT .1a it is 1.0amps - which - interestingly enough is EXACTLY what my iPhone3g power cube right next to it delivers.
The .7am Samsung charger has the usb connector on the side, and is part number ETA0U60JBE - delivering 5v at .7 amps (30% decrease over the little cube device). That was the charger my SGS-II had. My S/R came with the 1.0 amp ETA0U80JBE version.
One amp will charge the phone MUCH faster than the USB port. Per the spec, the typical USB device cannot drain more than 500mA (1/2 of what the power cube supplies to the phone).
Unfortunately Apple and Samsung both have the cubes pretty well locked up, so I cant compare the components, but at a first glace they appear to be absolutely identical, both putting out about 5.1 volts at zero load.
I had the infuse on the AC charger the other day, when I took it off, it had a message stating charging stopped because of battery temperature. Now battery will only charge to 35% no matter how long its plugged in. Also when phone is off the charger, phone is getting very warm to the touch and the phone is not being used. Do you think I need a new battery or is the charging circuit messed up? Thanks for any input!!!
Sent from my SAMSUNG-SGH-I997 using XDA App
If your able to plug it in and it shows it's charging then there is noting wrong with the circuitry. Your gonna need to replace the battery.
A new battery is much cheaper than a new phone.
Batteries heat up as the internal resistance increases over time. As Axiomkid suggests, get another battery. Do it soon. Old (or defective batteries) overheating run the risk of shorting, leaking, or exploding.
Better yet get two batteries and maintain them properly ie discharge to 10%, recharge to 100%, then swap out with another battery and let the recharged battery cool down.
Tried a new battery, it charged to 100%... but drained 50% in one hour. When I charged it again same problem is still happening. Thanks for all that helped.
Sent from my SAMSUNG-SGH-I997 using XDA App
You might need a new charger too. are you using the original Samsung charger? Try charging it from a PC too. The 50% drop in the charge could be a calibration issue too. It would improve that reading over the first few charges with the new battery.
yes i am using original charger, i have use a captivate phone charger as well. i think they are both the same. i'm thinking something is wrong with the phone because after charging and taking the phone off, the phone is getting really hot without being on the charger. like the phone is being used but it's not. could maybe the rom cause an issue like this? i'm thinking maybe trying to flash the phone with a stock rom and see how much the battery drains
Problem solved!!! Reflashed ROM and all is good

My wife had a problem with the screen on her EVO SHIFT so she went to a sprint store and they ordered her a replacement phone. it came in on Friday. I have it rooted and running a custom rom and kernel. that part is OK. HOWEVER, it doesnt seem to charge. I have tried 5-6 different cables (AC Charger). It seems like it is charging and you can see the charge % go up SOME but it seems to never get past 50%. I also tried different batteries (I have 4 spare batteries). The Amber charger light is on and the phone says it is charging and connected to AC.
Any ideas what would be causing this? I thought about it being a bad charging port but it is showing connected and charging... Any help would be appreciated....

What ROM/Kernel are you running?
You might want to let the battery drain completely, then plug it in and see if a battery charges. If it does go to 100% (which it should), then thereafter, reset the Battery Stats.

Running Supreme Sense X with dodge kernel 1.6.. his evening I got it to charge to 100% and the green light came on.. took it upstairs and plugged it in after a few minutes... the light came on amber and it said it was charging but after about 2 minutes went off and was no longer charging.. I then pulled the charger out and pushed it back in and it started charging again. I giggled the cord and the light didnt go off.
HOWEVER... just went in and the light is green again.. picked up the phone and giggled the cord.. light when off.. then I unplugged the charger and plugged it back in.. now its amber again.. I wonder if it is the port.. this is a replacement phone we got from a service center that we had to wait over a week for. I would hate to have to un-root and take this back for a second time.. its a pain to unroot and then get a phone and have to downgrade and re-root.
Im reading that the EVO SHIFT has a LOT of bad charging ports.. is this true?

The EVO Shift does not have a history of Bad Charging ports. Because it's a Refurb, there may be a possibility of it. But it might also be that when you jiggle the USB Cord your momentarily interrupting the connection enough to make it think it's been Unplugged. Then the device detects that it's plugged in, it starts the charging process all over. Also as a built in safety most devices do not charge the Battery to 100%. What happens is the Battery is charged to a preset level. Usually between 95-98% , but it will register as 100% . This is to prevent overcharging of the Battery. That is why when you first unplug a device the battery appears to drop the first 1-5% very quickly. Then drain slower after that.

If you have another shift, check the battery in it. I've said before, and I'll say it again....some of these shifts end up with a bad sensor somewhere for the battery. GF has the same problem with hers, but when I use her battery, it's charged 100%. Phone needs to be replaced, or needs to be checked in hardware. It's not a rom isse, charging port issue, or anything else.
There are several chargers available at Amazon. Maybe this would be a good option for you. http://www.amazon.com/s/ref=nb_sb_s...prefix=battery+charger+for+evo+shift,aps,1622

...pretty sure it's not the charger. The charger doesn't decide when the battery stops filling. Something isn't reading correctly. Maybe it's a system issue, something software but not the rom (like a faulty BIOS as opposed to the OS)

The charger can sometimes be an issue if it's not the Factory Charger, or a suitable replacement. I've seen several people run into issues by not using the correct charger. It is quite possible to damage the device, and the battery by not using the correct charger. Also some of the cheaper car chargers do not have an over-charge protector built in. While saying "over-charge protector" is a misnomer, what your actually trying to avoid is the battery continually trying to be charged when it's already charged. With some of the cheaper chargers it will cause the battery, and or the device to overheat.

Hi guys,
I got a mt4gs a week ago and it charged the battery at first but then after 3 days of use i connect it to the charger but still the battery is discharging, I got another battery but still its discharging while connected to an ac adapter. I am rooted and running miktouch 0.5. should I return the phone?
If it's doing the same thing while connected to your computer thru the USB, I have to admit it DOES sound like a mechanical issue.
That was happening to me awhile ago too. Mine was due to the USB charging pins being bent. I took the phone apart and was able to bend them back using a safety pin.
You also might want to try a different cable.
As a precaution, I bought a couple ankers and wall charger so I always have a spare.
Good luck.

got a new charger but still didnt work, going to return it.
Also have a weird battery problem on mt4gs.
Battery seems to drain while connected on AC, whether it's being used or not, but a restart shows it with more power. e.g. if I restart @ 52% when I restart it says 79%. if I restart again it may be 32% or another almost random number. sometimes 17%, 82%, 92%. I've tried all sorts of apps and wiping batter stats in cw.
Once I left it off and plugged in and the led turned from orange to green. But power on showed 92%. I tried two different batteries, it seems to be the same.
I worked properly before and I can't seem to remember when I realized it was doing this. Yesterday I also noticed, when I pull the battery for a while date and time resets. Dec, 1 1974 I think, Internal battery dead?
Anyone have suggestions?

I'm also having that problem with mine. Its in the cm9rc buglist, affecting users of some aftermarket batteries. I have the Hyperion 3500. Suspecting battery firmware issues...its always been a little strange. Reporting %100 for way too long, then declining normally for a while, then dropping from %30 to nothing pretty rapidly. Now on CM9 rc reporting is just random and inaccurate. Time to spend for an Anker. Ready to get rid of this heavy double-thick battery anyways. With consistent improvements in battery life I don't think I need it anymore.

Heard my tab dying from across the room so I went and got it to charge it and it won't bring up the charging animation. It also will not power on while plugged in or unplugged. It still has some remaining power because I can get it to boot into Odin mode but that's it. PC will recognize it in ODIN mode but no visible signs of charging.I am rooted on stock everything else besides CWM. I have left it on in ODIN mode unplugged to try and drain the battery 100% to see if it will charge from dead but its been 10 minutes already so I'm not sure how long that will take. No charging via original charger, PC, generic charger, Galaxy S3 charger, iPad charger, etc...
Try put your wall charger in and leave it for at least 15 mins..
then long hold the power button for at least 15 secs..
this will wake it from deep sleep.you should see the charger icon flashing then can power again and turn it on.If the answer is no sounds like needs to be repaired.ive had this before mine went into deep sleep and i thought it died but came back.
Left it plugged in for 7 hours and it won't do anything now...
EDIT I'm gonna hope it s the battery. I ordered a new one from Samsung today, we'll see when it gets here. said 10-20 days. It seemed to me that the battery life was very short anyways when I got it secondhand. I could go like 5 days or so with my transformer as opposed to a day or so with this tab.
Ok, so I got the new battery and installed it. tab booted right up with 40% battery life. I shut it off and plugged it into my PC to charge as my oem charger is broken and I'm waiting for my new one in the mail. It (finally) charged to 99%. I let it drain completely so as to calibrate the battery and now it won't charge off the PC USB again...
Hit it with a TWO AMP SAMSUNG A/C charger. ie. SGS4 (Sorry for shouting). Max charging A/C rate (from memory) it's actually 1.5 A. Edit : here it is....
https://github.com/UpInTheAir/P6800...mmit/064a3f7de67380c997e21f9a899a5d4996eb80c4
I hope you never deplete the battery to zero again.....
Although there are "protection" circuit to hopefully prevent battery damage, deleting to zero can still do this. There is no memory effect in modern device batteries, but a large (uninterrupted) charge cycle will help with calibrating your battery. But to be always on the "safe side", not from zero.
Depleting to zero might not be the only cause, but hope using a better A.C.charger (that your tab recognises and allows full input) will help you. some chargers will supply the full charge current, but the tab won't accept it.

I found that if it goes flat it wont charge off USB, you need to charge it from the wall charger, like UpInTheAir said, not enough amp off the USB ones
I fiddled around with my charger and removed the connector that plugs into the wall and plugged a cable into it (prong was broken off my charger) and it charges fine now. Thanks for all of your time guys, looks like it should be OK now. Still waiting for a new oem charger in the mail.

When I had tab open and plugged ito my note 2 wall charger ( which is 2.0 amp 5v output) the battery stayed cold but the long silver metal strip to tbe right of the battery became warm to the touch...... not sure what tbat means though.
Is the note 2 charger too weak to kick start battery?

If the Note 2 charger works with other device, I can't imagine being a problem with it.
Sorry, haven't studied the internal hardware, so can't offer any comment on that.
If you could somehow connect up a external power supply and try charge you might have success or narrow down the problem (if it's actually the battery or part of the charging circuit). Maybe you could PM the OP of that guide for further advice. Seems he's been fairly thorough and recent experience with our device internals. But please report here your outcome, we can all learn something.

Adding to my previous post, there are many examples of this suggestion on the internet..........
http://www.techrepublic.com/blog/five-apps/five-tips-for-extending-lithium-ion-battery-life/
4: Avoid completely discharging lithium-ion batteries
If a lithium-ion battery is discharged below 2.5 volts per cell, a safety circuit built into the battery opens and the battery appears to be dead. The original charger will be of no use. Only battery analyzers with the boost function have a chance of recharging the battery

The cut-off level may be different, but same principle..... That's why it's been reported that a high capacity and good quality charger has been able to "kick-start" dead (sleeping) batteries into life.
I have no idea about using or obtaining / connecting "battery analyzers with the boost function" to your battery. Please refer to the previous tutorial link I gave you (which may or may not help).

Update on my tab. All efforts have failed so have ordered new batt and am awaiting arrival. Will post if it works or not so orhers may gain some insight if they experience similar issues.
Fingers crossed chaps.

I had a similar problem where I let my Tab battery drop too low. I tried various fixes, similar to the ones in this thread. Finally got it to work by letting the battery totally drain by leaving it on the Samsung logo, then opened it up, disconnect then reconnect the battery. Then charge using the wall charger. All good.
P.S. Be careful when opening the case. Refer to Youtube ''How To" vids.
Has anyone seen, or recovered from the below symbol (battery with yellow triangle and a crossed out plug)?
I left it in my luggage for a few days and when I took it out it was around 20% so I just turned it off. Later it wouldn't turn back on so I charged it overnight, over 9 hours.
I've tried holding power and volume down and I can get into Oden mode but otherwise it won't respond.
I tried the hold power button and touch screen for 30 seconds method as well, the farthest I got was the swirling Samsung screen during bootup, then it shuts off.
Afterwords it alternates between a battery charging icon and a (see attached) battery icon with a yellow triangle and a crossed out plug. Has anyone recovered from this?
I just passed one year since I purchased it and am in the middle of a long business trip where I typically depend on it so will be bummed if it's trashed. I don't mind replacing the battery but am not sure if this is the solution, and won't be able to get a battery for about two weeks so I hope there is another way. Many thanks!

For the sake of anyone who has a similar problem. I believe this was due to a faulty charger, which I bought off Amazon so assumed was good. I took it to Bestbuy and tried with one of the display chargers and everything worked as expected. It's a pain but at least I know the battery isn't bad.
