Battery died get a spare - Sprint Samsung Galaxy Note II

So yesterday at work the phone started going crazy and bootlooping and just tons of crazy stuff. Battery was reading 60 and then 5 and .all over. I was trying to flash a nandroid thinking it was the ROM. But it was the battery as I have a new battery and everything is great.
Amazon has them for $10. I'd get a spare, your battery is due. I had to buy local for more $ yesterday.

Ha ha zerolemon hands down

I'm forced to bump this from my recent experience couldn't figure out the issue with my phone. It stopped loading passed the Samsung splash screen off the charger. Bought a new phone after so many Odin re flashes failing to fix it only to randomly try a different battery and have it boot up right away.

Yes this device has reached the elderly stage. Yes I know you can still get a new note 2 but production of new note 2's ended. The ones being sold now are left over stock. Their battery could have been on a shelf for a year or longer before the customer receives the device.
I have helped many users over the past year with this battery issue. Some had only had the device for a few months. They could boot recovery and flash things or odin stock rom. Yet it would never boot past splash screen.
The problem is this device requires a bunch of power to run. Notice that the stock charger is 2.1 amps? If you user a monitor you will see that out of the 2.1 amps your phone normally takes around 1+ amp just to run. So your battery gets whatever is left over to charge with. If you have used a cheap charger or most car chargers you will notice it takes forever to charge. Point being if battery is weak then you can't boot without extra power such as a charger connected.
So if you have not gotten a new battery recently then it is in your best interest to go ahead and get one soon. This could be an issue waiting around the corner for you.

[Q] Rooted CM7 Incredible will not turn on or charge

First of all I'm new here so apologies if I'm asking a question that's been asked before.
My situation is this:
My girlfriend has an HTC Incredible. It's going on 18 months old. I rooted it a while back with unrevoked and loaded CM7 on it. It ran perfectly for quite a while. Lately, she's been experiencing a problem with random reboots, I'd say over the past month or so. She said it would reboot when she had it plugged in to her work PC so she can listen to Pandora and keep a charge. Last night in an attempt to stabilize it and prevent the reboots I loaded Go Launcher on it and made sure she didn't have an malicious apps. Well, today apparently while she was working and had it plugged in to her PC via USB it rebooted and got stuck at the HTC Incredible screen. So she pulled the battery. Since she pulled the battery, the phone will not come on. I've tried the power button plus the volume down, the power button plus the optical button, everything. The charge light won't even come on. So, any help from anyone would be much appreciated!

This may sound stupid but did she put the battery back in right?
Yeah, she did. I don't get it, I've googled the issue and I can't really find anyone having the same problem.
If you can't even get into hboot, it ain't good. Any way to try another battery just to rule it out?
power button + volume down + middle button is the ultimate reboot.
and yea I say try another battery -or- charge the same battery in an external charger and try it again. If not then something really weird happened to that phone..
I'm going to try a new battery tomorrow. Dumb question : Can a battery just die like that? I've always thought there would be warning signs.
The random reboots are the warning signs. My phone was randomly rebooting last month about twice a week then one day it rebooted as I stared at it six straight times. Apparently my battery (it was a Seido 1750) was known to flake out after a few months according to reviews on Amazon reviews. These reviews were posted after I had my extended battery for a few months so I was unaware. I switched to my stock battery and I have gone four weeks without an issue.
My seidio 3500 occasionally likes to discharge in an extremely rapid fashion. I hope I don't have to go back to my stock battery... Ever!
Happens to computers. Power supply starts to go bad and you begin to get phantom restarts. Then your PC is dead.

Thanks for the help everyone. I finally tried a new battery. Doesn't work. The phone still will not charge. I'm at a total loss as to what to do. If nothing else works, I'm upgrading my Droid X to the Droid Prime (when it's released) and giving her my X. If anyone has any additional suggestions...it would be greatly appreciated.
I would throw that usb cable away...
If the cable is shorting out it can kill our phones because of the extra pins for TV out in the micro-usb port on Inc. +5dc on a video out line might have toasted it.
Just a thought.
good luck

Phone all of a sudden not charging

So suddenly my note 2 running tweaked has started charging real slow then all off a sudden will not charge at all. Ive tried several chargers and now have noticed with or without the battery i can enter only download mode and it will show up on odin but not charge the battery. as soon as i try to restart instead of entering download mode it will try and start but just shut down. Does anyone have any thoughts or ideas or has seen this issue? thanks. so considering it will enter odin is it possibly a battery issue,although it will only go into download mode nothing else? thanks again
The issue is not the ROM, I can tell you that much.
I would suggest flashing the stock kernel. If that does not help the issue, you need a new battery. 100% positive. I say that because you claim you have tried other chargers.
i cant check but can anyone else confirm the phone wont work without battery in with it plugged into laptop

It doesn't. You have to have the battery in, even when plugged into a wall charger.

awesome i am currently only 6500 miles from home in south korea.......seems like samsung is pretty popular here. lol everyone has a note2 here i swear. gonna find a battery and hopefully it solves the issue.
I'm having a sort of similar issue.
This is a brand new issue for me. I've been rooted running Jedi X-14 for about 2 months or so now. I went on vacation to Guatemala and that's when the issues started arising. I brought along the same charger I used here back in the states, and it worked fine the first day or two, then new things started happening. It started taking about 5-10 seconds for the Note to realize the charger was plugged in. Then when the charger was plugged in the bottom of the screen (actual touch screen) started becoming a bit unresponsive and laggy. The phone no longer charged as fast as it used to. Then sometimes I would plug it in, and it wouldn't actually charge...it would make the noise recognizing something has been plugged in, but would say "Please Connect charger". If the phone completely died this was almost a guarantee and I would need to plug/unplug/plug until the dead battery icon changed into the charging battery icon.
I'm back in the states now, haven't had a chance to reset/install a new rom or anything, and my phone earlier tonight went dead. Spent a good 2 minutes fiddling with it, it eventually turned on, said no charger was inserted, and turned off. Since then I have not been able to get it on. As soon as I plug it in it shows dead battery, and very rarely it will start to boot up the battery charging symbols (battery symbol with green bar moving), but even if it did, it would do it for 1-3 seconds and shut off.
I'm able to get into Recovery Mode/Download Mode, and the phone will actually stay on as long as it's on the charger (wall outlet).
It's not the battery, as I have another official Note 2 battery (at work currently, and I switched them the other day, to see if the other battery was the issue). Also I have different USB cords/chargers, and they all give the same issue.
From CWM Recovery I was able to wipe Cache/Factory reset the phone, but it still does not boot up. Any advice is appreciated. I can probably get it on when I get my other battery which is near fully charged at work, but I won't be at work for another 2 days or so, so I'm looking for a fix so I can have a working phone in the meantime. Thanks in advance.
EDIT: I was able to charge the phone while in recovery mode to about 10%...It then turned on...after a few minutes however the charger just stopped charging the phone. Tried another charger same thing. Tried both chargers with an s3 I have, and they work perfectly fine. Even going back to recovery mode won't charge it anymore.
I was on vacation in Central America and the same thing happened to me. It works fine in the states now.

Maybe its the oversea power grid? If you are using just a wall converter (US to Wherever) and still using your american AC adapter, you have to realize the power grids arent as clean or as constant as they are here in the states and can actually ruin an AC charger. Can you charge it via your PC using the USB cable? I know the stock Kernel has a near trickle charge though but still, it might be enough to charge it for use.
Something to keep in mind, the S3 has a lower power draw than the note 2. The screen alone on the note2 can draw more than 600Mah which is more than a standard USB adapter can output. Thats not counting the draw on the battery from cpu frequency or radios.
Also I can also assure you that bad power grounds cause a touchscreen to act up. I have an iconia a500 that acts up in the same way with a generic charger, yet, with the stock charger it works fine. It has less power filtering in its charging circuitry. I still have ungrounded outlets in my house which cause the issue. Too much interference.
Just a guess as both you and ryan are experiencing similar issues and are both away from home.

I figured maybe my charger from the US I had brought to Guatemala had broken...when I got back to the States, I bought a Micro USB charger from one of those vending machines in the airport (says it's a 5V2 1A wall charger- 2.1A output)... Having tried different chargers, batteries and outlets, I can only assume it's something with the Hardware no? I was able to reset the phone, and installed Jedi Master 14 to replace Jedi X14, to see maybe if something with the ROM was faulty, and that didn't help.
Phone no longer charges in CWM Recovery like it did last night. Phone turns off, and has that dead battery symbol on the screen (empty battery with a loading circular icon on it). It will no longer go any further.
Tried charging thru my computer to the same effect... worst case scenario I have to do a warranty exchange, however I'd like to avoid it as I believe T-Mobile no longer offers the White Note 2 and I don't like the titanium colored one, I'd have to un-root/stock rom/Triangle Away, and then re-root new phone (I'm a complete N00b at this stuff so it's time consuming for me to do), and honestly I'd just to avoid it if at all possible.

Well, its tough to say without using a multimeter and checking a few points, but, a power spike could fry the charging circuit in the phone. Thats the worst case scenario. Only thing you could do if thats the case would be to get a second battery and external charger.

Luckily both can be gotten from eBay for under usd $20. Its probably worth checking asurion to see if they have white ones in Stock. You just have to weigh the cost of a warranty replacement the hassle of changing batteries every day.

I just experienced the same problem with my N2 over the weekend. Went to Bestbuy and got the $50 battery charger and extra battery (Check local availability) price matched to Amazon.com for $30 (with free shipping under more buying choices), brought it home to charge my completely wasted original battery and used the one in the box. Sure enough, it is the charging port. The new battery did the same thing as the old one, it showed it was being charged by the little lightning "icon" over the battery, but the battery was still draining. Although the lightning icon was there, there was no "bing-bing" tone (in the stock rom w/ root) to indicate the cable was ACTUALLY connected.
What is interesting is I think the battery icon shows up as "processing" if the USB pins are connected, but if just the +/- terminals are used in the cord (like the one that comes with the battery dock, not a MicroUSB cable -> USB port -> power adapter that comes with the phone, but power adapter -> MicroUSB) nothing registers on the phone even if it's completely powered down.
Called Tmo today and they are shipping a warranty replacement to me for free, I just have to wait for Ground shipping (didn't pay the $20 for "overnight"). Hopefully it'll come by next Wednesday, as I'm leaving on vacation then. With all this drama on the phone, I actually ended up ordering a Nokia 521 (give old WinMo a try again) from HSN over the weekend as a backup phone for $100. I felt like I was going to die not having a phone for 2 solid days.
Normally they send one out , then you return yours. The battery on this phone is phenomenal, so using an external battery charger and swapping them out would be viable while waiting for the new one to come in the mail id think.
Im hoping these phones dont get usb charging problems often. I might just mod mine to take wireless charging. My s2's microusb port died on me.

I'm actually quite disappointed that Tmo told Samsung to not wire up the wireless charging leads on this phone. I would be totally on-board for wireless charging a'la Nexus or my Touchpad. My Microusb connector wouldn't even see any use other than when to flash a rooted update.
I'm OK with a soldering iron, but I don't want to tear the thing apart to hook them up myself. Seems like it would be a great way to void the warranty, OR disable my Squaretrade warranty.
Just wanted to drop back by since I was about to send back my N2 to Tmo... I unrooted, triangle awayed and finally flashed "clean" firmware directly from Samsung via ODIN.... both batteries are now charging via both USB and Power adapter.

Galaxy S3 (Telus - Canada) Charging Problems

Hi all,
I am hoping you can help. I am having a problem with my Galaxy S3 and I am trying to figure out what the problem is and how to solve it. Around the time of the 4.3 update I started noticing that my battery started to drain very quickly. Initially I just assumed that there was an issue with one of the apps or something in the 4.3 update causing the problem. I then started to notice that my battery would not charge past 51%. Here is the list of things I have tried to fix the issue:
- Different chargers and USB cables. I have tried charging from different power sources in my house and at work, also using my car charger and other peoples chargers that have a S3 that have had no issues.
- I have tried 2 other batteries which I purchased new, one official Samsung Battery and a 3rd party long life battery
- I have done a factory restore multiple times on the phone and also tried rooting and installing a custom ROM to eliminate software.
- I have checked the micro USB port for dust or lint and tried my best to clean out the connection. I haven't been to rough with it because I am worried about breaking the connection.
- I have tried charging the phone without the otter box on and I was worried that might be causing the charger not to go in completely and give a bad connection.
I have GSam installed and when the phone reaches 51% and you look to see the time till charge it always says - Calculating please come back later.
At no point when I have the usb cable in for charging does the charging light go off. Even after the battery hits 51% the charging light stays on but does not charge past that point.
If I leave the phone charging overnight I wake up in the morning and it says 100%, but as soon as I remove the charger it immediately drops back down to 51%. The outcome is the same with all the batteries I have, the only difference is the amount it charges up to. It seems to range from 48% to 51%. I have also tried charging with the unit off and on and can not get it past 51% on any of the batteries.
Any ideas or advice would be greatly appreciated!
I am having an issue myself with charging my S3. I ran into the same problem as you initially and ended up using ODIN to go back to stock. That fixed the drain/charging issue. However now mine wont stay connected. I believe the charging/USB port is going on it. I saw a lot of Samsung phones on Ebay with the same problem so it must be an issue with them. IDK if that could be your problem as well. I tried calling AT&T for a warranty replacement but they wanted me to pay the insurance premium ($200) for a phone that came out in 2012! The S5 will be out soon, they're nuts if they think I'll pay that now for a S3. The only way for me to get a full charge over night is to plug in my phone, then put my high school yearbook on the charger to apply pressure until the green light goes on. It sounds funny and honestly it is, but I'm cheap and don't want to pay the $200 until it's actually dead or I get my tax refund HAHA but then I'll probably just get an upgrade.
I was thinking of buying an extra battery with a external charger to see if that would help. Maybe if you get the external charger, charge it up then put it in your phone it will charge all the way.
Thanks for the reply. I haven't had an issue with the charge light not coming on but I am starting to think it might be a calibration issue. Somehow the issue has changed slightly. It still says 53% when i take the charger out but sometimes the battery life will increase while it is not plugged in. I am assuming that it is reading the % wrong. I am in the same boat with sending it off to repair. They want $150 as a base cost and I am worried that it might turn out they say No Fault Found and I am back to square one, and $150 shorter. I know what you mean about the S5 coming out soon, so I might try and wait it out until my contract is almost up and upgrade to the S5.

Phone dies at 20% like it's 0%

Hey Guys,
My wife and I both have a Sprint Note 4. She runs hers stock and I am always looking for the next ROM. Currently I'm running the newest Hybrid X 3 rom. I'm posting this here because I don't think it's ROM specific. I've had this problem with other ROMs too and I'm curious if anyone else has...
Our phones will just die at 20% like they're dead. And my phone just did it at 35%. Not sure what is going on..
If anyone has ideas, let me know. I do need to run a battery calibration tool, but I've read other places that they don't work.
Thanks,

My phone has done that too a few times. I'm on stock rooted KitKat and sometimes it will die between 6 and 10% so it could be a calibration issue. let me know if the app you try works and the name of it. Thanks
I've probably done this without thinking much about it. I had installed Xposed and disabled the low battery warnings and totally ran it to power down. Knowing that Sammy used to use a panic rob of ~20%, I charged fully with phone off and then powered up. I believe at step 3, you should leave the charger plugged while powering on. I'm not sure but it seems the old calibration data will be applied if you remove charger before booting.

If that doesn't work, try the OP of Noterized or OBAR.
Edit: The 2 run to 0% shutdowns were done on OB7. I've ran OG5 down to 5% with no issue so far. Still running original battery since day one and get max 10.5 hours SOT.

Its an issue with the new ROM. I too get this all the time. My cousin also gets this on his Tmobile Note 4.

Yes same here, fully stock.

That's just odd to me. I've been running rooted stock Odex from tx_dbs_tx OB7 to OG5 tar ball. Still using the OB7 bootloader and I've been running the battery capacity down to 5% before charging without any false shutdowns that suggest it's actually 0% prior to charging.
Phone has been running fine. Only a couple of odd issues to report is the messaging app shutdown without explanation or notification while I was composing a text message; went black screen and came back to home screen. I thought it may have been some settings? Yesterday, I tried to update Milk Music and got a -505 error from Google Play. I had to remove Milk Music from the system and data directories and download from Play to get the update; clearing the app's data & cache or uninstalling the previous update and rebooting made no difference. Prior to that the app always launched but on a couple of occasions inexplicably wouldn't start playing music after pressing play a few times; never showed a pause icon, just flashed play icon each press but no music. Appears to be stable despite that; phone and Milk Music was ready, willing and able this morning for a brief workout with V4A and Dolby Atmos to pump up the beats.
I've gotten as much as 10+ SOT rooted with Beastmode kernel on this build; pics posted in freeza's Beastmode kernel 5.1 hello root thread. Fully functional AFAIK, now. No freezes, shutdowns or reboots.
Here's a thought. If the simple fix I posted earlier does nothing, backup and wipe everything but the ExtSdCard and format the data partition a few times. Select reboot to power off and pull battery for 30 seconds. Reflash the stock tar or the other tar ball if actually using OB7 bootloader in Odin and let phone boot normally with auto reboot enabled. You should see the stock recovery open briefly to update the csc files and boot. Once it boots, don't get in such a hurry to go through the setup wizard because the phone will interrupt you saying it needs to reboot to complete installation. Reboot and run the setup wizard.
For rooted users, I'd recommend doing the above steps before root or flashing custom files in Odin or TWRP. For non rooted users, simply flashing the stock tar with Odin or KIES wouldn't void warranty or trip Knox counter. Do the factory reset first and make sure the Reactivation lock is disabled. There's also a Knox active protection setting in Settings/Security that can enabled to protect and root if lost; disable that prior to factory reset and power down prior Odin or KIES tar as well.

I've had this happen to me a few times in the last 2 weeks suddenly out of no where and at varying battery percentages. It's happened at 20%, 12%, 10%, 5% to name a few.
I am completely on the latest 5.1.1 and am not rooted. It's really annoying. Wonder if the batteries are beginning to cut out, maybe defective. I've had my Note 4 since it hit the stores.
I'm seriously thinking about contacting Samsung to file a warranty claim.
I had the same problem
My phone would die really quick ones it reaches 20%
I bought a new battery and problem solve
Sent from my SM-N910P using JellyBombed Tapatalk 2
Mine did that a time or two and of course at the least opportune times
My old battery would drop from 30% to 0% within seconds. I took it to the sprint store and have them tested. Sure enough, there are issues with the battery. After getting a new battery, problem solved.
P.S. The Sprint rep told me I shouldn't leave the phone plugged-in when I go to bed.
Well either purchase new battery or just try to calibrate It like older times. May be calibrating it give you desired results...

Contacted Samsung and was told to boot into safemode and run the phone without 3rd party apps loaded to see if it still did it. I was aggravated naturally because I need my apps. Well I did it and sure enough, the phone behaved properly, did not shut down unexpectedly. Now I'm really mad. I still think it's the battery but it was hard to prove that with safemode not replicating the issue. Can some of you try it and let me know your results. Thanks.
Freddie: Below are the instructions for Safe Mode.
Freddie: 1. Power the device off (remove and re-insert the battery after 30 seconds).
Freddie: 2. Press and hold the Volume down key, then press and hold the Power key.
Freddie: 3. When the first boot screen displays; release only the Power key.
Freddie: 4. Keep pressing the Volume down key until the device boots up completely
Freddie: 5. If successful, Safe Mode will appear on the device screen in the bottom left corner.
Was having the same issue, from 30% it would go down to 5% in an instant, or at 25% it would just die and reboot. Replaced the battery with an anker battery off of amazon for $12 or so, battery has worked perfectly since then.
I just bought two batteries off Amazon, but has anyone had success getting a warranty claim validated through Samsung and actually get a new battery without hassle. I would love to have two new stock batteries as my wife's and mine are doing the same thing.

Not yet, I just bought a new battery from BestBuy yesterday and got them to price match Amazon. Hoping I see a difference with the new battery and then will go back to Samsung and let them know that fixed it and maybe convince them to replace it under warranty.
I just can't stand that they want me to factory reset and not install any apps to make sure it's the battery. Maybe I can send in the bad one and have them test the battery. That might work.
My phone just started doing this within the last week or so. My phone is only 11 months old too. Yeah guys, let's seal the battery up so nobody can change it on their own #note5. Another service they can charge $$ for. So it looks like the go to solution is a new battery? Sprint is selling a wall charger w/battery right now for $25, pretty good deal. I am going to try calibration too but am not confident it will help after what I'm reading here.
At least I won't spend much more time trying to 'fix' it. Thanks for the thread!
So, after a little while with the new battery and actually using both because, hey, it's nice having 2 batteries it happened again on the old battery. I actually wiped my phone yesterday and so it's definitely the battery.
Contacted Samsung again today and reference my previous chat. Agent was very quick to give me an RMA for the battery and upon request, even sent me a UPS return label.
Moral of the story, be persistent and they will replace the battery.
Well my battery has started showing failure after 14 months. Last week I rebooted my phone at 15% and it failed to boot; went black. Plugged the charger in and it said 0% charging. Ordered another battery. Deleted the /data/system battery bin stats, charged to full and verified in off condition that it's fully charged.
Still waiting on the replacement battery; delayed due to bad weather... started a benchmark at 26%, today, and the phone shutdown before I returned to check results. Plugged the charger again and again it says 0%. LOL.
Samsung makes a good battery but my experience with them has been the lying% indicator worsening with age. For me, that circuit seems to go before the battery usability goes. I was still getting 5+ hours SOT with heavy use before the % error started. I get more 8 or more SOT if just browsing the web and tapatalk. I'm running stock rooted and have mostly ran just that. Battery is original and I haven't had a backup until ordered. The same battery once got up to 10.5 hours SOT back in KitKat do it has degraded over time.
Not replacing with a Samsung battery. Sorry Samsung. Just unplugged charger with charge showing at 85% and battery % jumped to 100% (the note 8 tends to do this also, even before rooting it). Been using it awhile since unplugging and it's still at 94%. It doesn't drop fast; it just lies and has died twice now near the 20% remaining. Last set of third party batteries I purchased didn't do this and didn't drop 10% on a reboot either. Samsung % seems to get a little dishonest post 50% when rebooting. It's a good thing I've charged to 100% before flashing in recovery or Odin lately. This doesn't leave me feeling warm and fuzzy about buying a phone or tablet with non user replaceable battery, Samsung! However, I'm thrilled I can pull and play a $12 replacement battery in a jiffy on this Note 4!

Bone stock 5.1.1 bootloop

Just bought a refurb Note 4 off ebay, no scatches on screen and negligible scuffs on body edges.
Battery was dead when I got it charged fully and then started playing with it.
After about 2 hours of use it restarted and just shows the samsung logo.
If I plug it in it will charge and boot up to Verizon logo.
Can get into recovery only when plugged into charger.
Factory reset gets me to the Welcome/Setup screen but reboots after I select English.
It only fully booted two times and restarting brought back bootloop.
My thoughts are a dud battery but I have no spare to test atm.
Thanks for reading.
Update
After flashing stock with ODIN and multiple battery pulls the only thing that worked was letting the thing sit and bootloop until the battery drained.
Phone booted up fine but will now shutdown immediately after I unplug it.
Ordering a new battery as this seems the most likely culprit.
Also when plugged into outlet I can take pictures but if I turn on flash it reboots.
Will be contacting seller about battery issue.
I used the resources available from this site for ROMS and ODIN thanks.
Resolved
Slapped in a $20 ANKER from Amazon and phone is working great!
Although nobody replied the resources were here and I am grateful.
Paid only $160 for the phone + battery.
