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,
PhotoshopGeek

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.
I spoke to a Sprint Rep who also stated he has the same issue with his 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!

Reboot loop until plugged in?

So my wife's Note 4 is on the latest 5.0.1 update from Verizon, and lately has developed a strange issue. Anywhere between 0-30% battery life left, it will go into a reboot loop. If you let it reboot over and over long enough, the Verizon screen gets shorter and shorter every time, before it finally gets to a black screen with small red text in the top left that reads "Secure fail: modem" and a large yellow exclamation point in the center, and instructs to use "VZW Software Upgrade Assistant" to fix the issue.
But even more strange, is once she plugs it into a power source, she is able to boot it up fine with no issues until the next night the same scenario happens all over again. She's never modified any software, attempted to use temp root methods, etc. and has always run stock OTA updates. She has also tried factory resets and the issue returns a few days later.
tl;dr Random reboot loop every day, eventually leading to "Secure Fail: modem" screen until plugged into power, then boots/runs fine until next day.
Any ideas of what could be going in is greatly appreciated!

My note 4 had the same problem. Battery would get to 30% die, and reboot constantly. I bought a new battery but it made the phone do the opposite then. Now it will on charge up to 65% and no more. But, it will reach 0% before it actually die. It is a glitch in 5.0.1 that affects several galaxy phones. The sad thing is that it is NOT the latest update. Currently 5.1.1 is, and Verizon refuses to release that for unknown reasons. Sprint is the only carrier that pushed 5.1.1 after these problems started. Other problems are the note 4 crashing, battery drains, overheating, poor processing, restarting out of no where, slow, and app crashing. I myself, is unhappy with the note 4 and I am most likely going to go with a different phone. (which is sad because my note 2 was just awesome.)

Verizon is going straight to 6.0 because of all the bugs even with 5.1.1. Good move on their part I think.

I'm having the same problem. mine starts anywhere from 40-50% battery life, will reboot till phone is dead. As soon as I plug in the charger it will start charging the battery at what ever % was left.

My phone went into a reboot loop this morning after a full charge for the first time. It has never done this before andI tried to stop the reboot loop by entering bootloader/safe mode screen and I did "reboot" but my phone went dark and has not responded since. I believe it is bricked. Anyone have any ideas?

new battery fixed my problem

had same problem new battery fixed it

New battery fixed for me too.

I'm running into the same boot loop issue and I see that basically 5.0.1 caused it and 5.1.1 has fixed it... And the only fix is a new battery... Anyone try getting Verizon or Samsung to go good for a new battery since it was their software that damaged it?

Bootloop when not charging

Hi, I have a galaxy note 2 n7105 which is rooted with stock rom on. This evening, while i was texting, it suddenly shut down. I tried to turn it on but it just showed the phone logo on and off. I got home and charged it and it was working fine again. But as soon as I unplugged it, the phone just turned off, despite showing 100% battery. I try to turn it on but it just keeps flashing the phone logo on and off for hours. Basically, my note 2 bootloops when not charging, and operates fine when charging. I suspect it is a hardware problem as I have flashed the stock room again but to no avail.
Thanks in advance.
Update:when i unplug my note 2(which shows 100%) from my charger and plug it back in, it boots at about 18%. most likely the battery. the note 2 can also boot into recovery even when unplugged

Check the battery to see if it appears defective (swelling, leaking, corrosion).

My pixel 2 xl on Android P not passing 99% while charging

I just upgrade my phone to android p. I have charging problem. My pixel 2 xl does not passing 99% while charging. It stuck like that all the time, never reach 100%.
I try restrart my phone while plug in the charging cable, the battery show 100%.
Is this my phone battery problem or software problem and how to solve it?
TIA :crying:

Probably best to run through a couple charge cycles and see if it rectifiers itself :good:

I have the same problem after updating Android P Beta (5) before the officiel Android Pie and i don't know how to solve this!

Had this happen to me twice before when flashing different roms etc. I've noticed it goes back to normal with a few charge cycles, hopefully its the same for you

I have actually had this issue for over a month and it goes to 96 to 98 most times but 99 &b 100 are rare. Spoke to verizon yesterday and getting a replacement today. I tried all different methods to correct it and no help.

Guys, I just want to share a troubleshooting tip that works on my Pixel 2 XL. My phone battery has been facing a charging issue which was unable to fully charge to 100% (stopped at 97% or 98%) since updating to Pie last year. But recently I did a hard reboot by pressing power and volume down buttons together for about 10 seconds, and voila! my phone can now reach 100% battery charging! No data loss, no factory reset, I think it just temporarily disconnected the battery physically from the phone. Hopefully it will work on yours too

I intermittently have this same issue.
The old school way to reset your battery stats (which includes the battery percentage) is to go to
data > system > batterystats.bin
delete the batterystats.bin file
reboot
batterystats.bin is automatically created after the reboot
There used to be a battery app that did this, but I think it stopped being updated with Oreo, because Play Store no longer has that app.

(SOLVED) Pixel 2 XL charging stuck at 99% all of a sudden

My 2 XL is only a month old. There is no complain about charging before. It was normal. Hit 100% everytime. Until several days ago, I woke up in the morning and my phone does stuck at 99% with charging rapidly status. I've tried to drain the battery and fully charge, try to flash factory image, but the problem still exist. The phone does charge normally to 90%, then getting slow and more slow when hit 95%, it takes very long time to get to 99, then it stuck for hours. I'm using app called AccuBattery, just want to monitor the charge speed. And there it is, the phone stop the charging at 99%, charging speed shows -1 , so basically the phone cut the power input when hitting 99% although the status still not fully charged. Until I rebooted the phone then it will hit 100%.
So what happened to my phone? I'm using original charger from the box. Is it software or hardware issue? Thank you
The first image is when stucked on 99% and the charge speed show -1. After that I rebooted the phone then charge speed increasing, not -1 anymore at 99%. The second image is when the phone says fully charged at 100% and charge speed back to -1, which is normal if the phone already fully charged.
EDIT:
Solved - see my post below

What is it at though? But on all my previous rmas, I had sometimes great issues in from charging past 98%.. I would have to turn it off for it to register that it's actually charged to 100% and more than likely it would drop to 99 as soon as I unplugged it.

I can't asked for RMA. Pixel didn't sold in my country. I bought from local seller that handcarry the unit into my country.

Yeah I got a replacement at the time but not for that sole reason so I don't know if it would work but I don't think it's that much of an issue if you are still getting 6+h sot

Yeah, I'm planning to do that. I'm just uncomfortable with my phone acting weird, it supposed to hit 100% everytime normally like before. And a little afraid that this issue would make any affect in the future, broken battery or worse. If there's an explanation how this is happened and it's safe, then I might not make any complain anymore.

I had the same issue with my Oct 18 2 XL.
Download Accubattery and "calibrate" your battery.
It removes a file (.bin or something) that resets the batter charge percentage.
I really think the 99% thing is harmless, but if it bugs you (I get it) Accubattery will remove the file that resets it.
Good luck!

I currently using AccuBattery as shown on my post attachment and I didn't found any "calibrate" menu inside the app.
I've done so many methods, like drain the battery to 0% and charge it or re-flash factory image but seems none worked. So I search on the internet about delete the .bin file under root/data folder, but I didn't found any folder called data on /root (currently running android 10). I'm stucked.
So I'm thinking how if pull the battery out and put it back maybe it will reset something, but it seems impossible to do with myself. Until I found a method to hard reboot the phone with press power button + vol down for maybe 10sec. My phone was 75% at that time, after hard reboot my battery increased to 78%. Then I tried to charge the phone and voila, hit 100% normally, didn't need to unplug and replug to hit 100% anymore. It's been 3 days my phone is act normal again. Hope it will lasts forever.
So my conclusion is, seems the hard reboot method somehow force cut the power from the battery to the phone just like we pull out battery then put it back and maybe it's reset something maybe like batterystats or anything. Idk. But I'm glad nothing happened and it was just software error.

Oh, I just realized that. Thank you. But I think it didn't work for me. Nvm, my phone is normal now :laugh:

I had somewhat of the same issue with my phone too. Would sit around 98% then after taking it off the charger overnight, my battery would drop like a rock to around 85%. No idea if I was just imagining things but I don't remember that much battery life wasted away like that overnight when not in use at all.
I also sent mine in for RMA last Thursday and get it back later on today so hopefully the issue will be resolved.

I have also been experiencing the same issue since upgrading to Pie last year. Once it returned to normal for 1 month only and then went back to 98% charging issue until today

I would assume broken battery. Never experienced drain so much like that when not in use. My phone normally about 1-2% drop overnight (always on display off). It's great you got replacement, but check twice for screen, 2 XL known for defective screen.

Yeah I am content with the RMA replacement it's just fine, no issues thus far. Just annoying the update breaks charging sound file and lockscreen lock/unlock sounds. But I eventually got those issues fixed too.
