(Not) Brick - Didn't Calibrate Battery After ROM

Right off the bat, my Revo is non-responsive, no buttons will light, backlight, vibration, sound, and of course no splash screen since the screen isn't lighting. The only sense that it is partly there is after a time connected to USB/wall charger the battery warms as if it is charging. Yet, there is no indication during charge on the screen, it stays totally black as described above.
I have been poring over forum posts, CWR threads, and the like, but have come up short on a method of reviving this puppy. thecubed had posted something that seemed promising but doesn't work for me here. At all steps, the phone remains non-responsive and connecting it to the PC yields no mass storage connection. The only step I have abbreviated is letting it charge for an hour since the phone had charged about four hours since it shut down.
Two evenings ago, I flashed from Revolt ROM 1.0 to 1.1. It was successful but since I had just gone through battery calibration and running my battery down until the phone shut down the day before when I flashed it to 1.0, I was hoping (naive?) that I wouldn't have to do it this time (yes, naive!). So, I left the phone on all night, on the wall charger.
I was using it the next day and at one point, while using it in a low reception area, browsing the web, it rebooted on me. No biggie, had that happen in the past. After reboot however, the battery level seemed different so I wanted to get it topped off then calibrate. 1-2 hours later I noticed that the calibration app was showing the mV lower and capacity was at 70%. The battery felt unusually hot. I shut it down, removed the battery and cooled both battery and phone in a small fridge to accelerate the process (was near time to leave work).
Next boot was I recall having an extra FC, one beside the CarHome normal FC with Revolt ROM 1.1. This boot the battery showed maybe 20% capacity so I said "screw it" and deleted battery.bin with the battery calibration app (I recall the mV was low, in the 3600 range). I discharged it on the way home and left the display on to run the last couple percent down. It appeared to try and shutdown but ended abruptly. That was the last time I saw any life from my Revo.
The day after its first and only ever root, I did have an odd occurrence which I posted.
Boot Trouble - Rooted After Phone Downloaded OTA, Not Installed
That time, I had not installed a ROM yet but the phone got itself into a boot up funk. Removing the battery, connecting to wall charger, watching buttons flash ~5 times, disconnecting (which stopped the flashing lights), then battery in, power on... success! I was hoping that would happen this time around but I haven't been able to.
Full history, being my first root, I used S1C successfully, installed Titanium Backup (ran system and app backup), and RevoToolkit. The phone did download the OTA but I never let it install, instead selecting to delay it by 24hrs when it asked to install. Fearing that deadline and getting one more warning that it wanted to reboot and install the OTA, I went ahead and installed the Revolt ROM 1.0. All went fine, no drama. The next afternoon I thought going to 1.1 was going well too, until this brick hit me.
My hope of hopes is it's just a bad battery and the phone won't respond because the mV is too low. Reading thecubed's comment in his first link (above) how recoverable this phone is lends me hope.

It sounds like a bad battery. I would take it to a verizon store and see if you can try a different battery. If it still will not boot then they should warranty it out for you.

P.s. I never do anything for my battery. I charge until full then use until empty. Yesterday with moderate tI heavy use I made it from 6am until 8:30 pm

Thanks for the responses. I will be going to VZW shortly to figure this out. This phone is maybe two months old so hopefully the battery is the answer *fingers crossed*
Impressive battery life! At my office, I'm in a bit of a metal cubicle area and a bit low on signal strength. My phones will sometimes use up the battery trying to keep connected, it seems, so I am usually plugged in most of the time.
While I have your ear, thanks for the great work on Revolt ROM. I am very happy with it and look forward to its future development

Good news and bad.
The good news was they swapped in a new battery and the phone worked. Having the warranty, it didn't cost anything.
The bad news is that it looks like there may be another problem. On the way out of the store the battery was indicating 1% so I quickly got it on the charger in the car. Driving home, about 10 minutes later, I got a warning for battery temperature. Thinking the low battery may just be taking a charge and getting hot from that, I turned the car A/C on full, took the back cover off, and kept the phone in the cold air.
In about two minutes, just feet from home, I noticed the display was off. Faintly I could see the battery charge symbol that shows when the phone is powered down and charging, but the backlight was off and I couldn't see if there was any color or animation to it.
As soon as I shut the car off and the power quit, that faint display disappeared, full black, dead. Now it seems it is behaving exactly the same. I haven't fiddled with it much, holding out hope of hopes it can be started and maybe recovered.
Could calibrating the battery at the wrong time have caused something like this? Do batteries have a safety lockout if they overheat? To be fair, I was running an intensive app at the time, Waze GPS. Maybe the battery didn't keep up and the phone decided it was too low and shut off. I will post back after letting it sit, cool, hopefully charge, and see what comes of it.

My phone is behaving exactly the way you describe too. A couple of days with Revolt 1.1, and this is the only problem. I had my phone hooked to a lithium ion usb battery pack all day, and it showed "100%" while hooked up, but as soon as I disconnected the battery pack, the battery icon changed to red, then it refused to boot like the situation described in the Revolt 1.1 thread in Development. It also would not go into charge mode on the battery pack, but when I came home and hooked it to a genuine AC adapter and it went into power-off charge display. I'm going to give it a few hours on the charger before I attempt to boot it again, and I'll report back.

Still no luck. I haven't charged it too much yet for fear that it isn't charging properly. Seeing the new battery work for about 20 minutes yesterday lent me hope that if I figure out how to get a fresh battery in or just shell out for another new one, I can have a window of opportunity to change ROMs and see if that has anything to do with it.

This morning I got out my digital multimeter to measure the battery pos to neg and am getting nothing (unless you consider 0.01v something). I tested my old LG clamshell's bulging, old, and damaged 1000mAh battery and it reads 3.99v but couldn't keep my old phone up (lacks oomph now).
Comparing that battery to the Revo's, they have the same four contact pattern but different connection scheme which just stops contact when test fitting. After shaving down its casing on the bottom a little bit, it was just enough to make contact. Using four hands (yes, I am very talented ) to hold the phone, hold the test battery properly, and hold the power button, I was able to get the power-up vibration and the first LG splash screen. We lost it after that but that's likely due to the very weak test battery and/or losing contact while holding it in the Revo.
Since the spankin' brand-new battery is now reading zero, I'm left second guessing my decision of not shutting the phone down when I got the temperature warning. Maybe these batteries do have an internal protection to prevent runaway failure and it too is trash. I have no experience with this otherwise so this is just guesswork.
I'm contemplating rigging the new battery into my old LG phone to see if it can tell it "all clear" and charge it up. I'll post anything I find out here. Any other suggestions are highly welcome. Still, last ditch, I'm pretty certain I can set up another ROM to flash on the SD ahead of time, get another battery, and Clockwork to test another ROM if it's the phone or ROM. I may have had 20 minutes of uptime on the last battery.

I think I've gotten to the bottom of my problem. It's a syndrome of things that I have hopefully untangled.
First off, I had been messing with Power Manager, and wanted the phone to not sleep or timeout the display when plugged into both AC and USB. I figured that would help when I'm plugged into the computer, but it was probably a bad choice.
Yesterday I was out on a boat, which probably put me into a weak signal area, causing the phone to expend extra energy staying locked on a tower. In addition, I had plugged it into the external USB power pack, and thrown them in a bag together. This did two very bad things: 1) It allowed heat to build up from both the charging and 2) it invoked the "USB powered" Power Manager profile which kept the display active which created both additional heat AND crazy battery drain.
Here's what I think happened:
1. The battery overheated
2. The USB battery pack couldn't charge as fast as the display and radio could suck it out -- so five hours in that mode BOTH drained the internal battery AND tapped into about 30% of the external battery pack.
3. The USB battery pack will not provide enough initial juice to restart a flat-dead, overheated phone, or the firmware "knows" it is hooked to USB and refuses to start the phone -- for some bizarre reason.
So, I think my phone demonstrated normal behavior for a flat-dead, overheated phone, and hooking it up to AC brought it right back to life -- after about 5 hours of continuous charging. The battery also got very warm during charging -- more than I recall feeling ever in the past.
I'm hoping there is nothing that software power management could have done to physically damage the battery, but I assume Verizon would claim it could -- as part of the reason they forbid system modifications, and therefore withdraw their warranty if you modify.
At this point I think I have dodge a bullet, and my phone is fine -- other than a few of the quirks others are seeing in Revolt 1.1 (Phone occasionally FC, etc.)

Good to hear your phone is fine. Seems like mine is too as posted above but time will tell. I got the Revo battery set up and charging on my old phone. It seems to be connected well enough. The phone complained the first try that there was no battery but my second try has it displaying that it is charging. The battery isn't warm at all but maybe that's due to a different charging rate for the old phone's 1000mAh battery vs. the Revo's 1500mAh. Or, it really isn't connected perfectly. We shall see.

Success. The surrogate charge setup got the Revo battery up to 4.11v and indicated charge complete. The Revo completed a full boot on the battery and appeared normal.
Not normal was quick heating (still unsure of the cause). Going straight to Battery Calibrator, it indicated 68% and around 3.7v and falling. Not wanting to push my luck, I shut it down. Battery now read 3.9v. Not bad but it sure seems to be getting drained quickly which would explain all the heat. Going to set up later and see if I can get it back to stock and see if the behavior persists.

I don't know how to fix any of your issues but I would like to say thanks for giving such a detailed display of what you've been doing to fix this problem should anyone else run into this issue. Also, That picture in you one post: That is the most jerry rigged set-up to charge a phone I have ever seen in my life and I love it. Good luck getting your phone working I hope everything turns out for the best.

You're welcome. It was a bit of impromptu brainstorming with some fellow tinkerers that helped come up with a way to test charge the battery. Having it come back to life
I've come to a conclusion. Somehow, I think when the battery overheats, it must internally soft protect itself. Charging it on the old phone reset it and then it worked again on the Revo. Why the old phone works and not the Revo, unsure. That would at least explain why the battery tested at zero volts before the charging rig.
After many starts and stops on my Revo now, I have found that what was heating up first was the casing of the phone. I'm guessing heat conduction of heat from the processor as it wasn't the display which was set to minimum brightness (those are the main heat sources, right?). Looking into Settings > About > Battery Stats, it only showed Android System at 98%. It seems like the processor got locked into some some high power continuous use situation which survived reboots.
The battery gets hot later due to the high consumption and proximity to the hot casing (processor), especially with the back on. Withing 1-2 minutes from start, the sides of the phone would be quite warm and after 5 minutes becomes concerning. It seems that's why the battery was never able to get to 100%, but instead its percentage was always falling, phone over consuming greater than charge rate.
With the processor going full tilt, battery cover on, protective case on phone, sitting in a warm car without A/C, that got the battery too hot within 20 minutes. It was a similar situation with the prior battery when the problem cropped up.
I don't know what the cause of this predicament was in the first place however. The phone was plain stock, then rooted, later flashed Revolt 1.0, then Revolt 1.1. Between Titanium Backup, RevoToolkit for CWM, basically nothing unusual, I have no idea how it happened. Maybe I should have done Decrap first since I've read others doing such. Thinking back to my first post/thread, I had a boot issue and only had rooted, Titanium, and RevoToolkit, no ROMs yet.
And, don't get me wrong. I'm not placing blame anywhere, just documenting my "progress." There was a time I was on Revolt where it wasn't behaving this way. I am left without a solid conclusion as to the cause.

How to avoid the battery drain?
I had a similar situation, downgraded and then installed Revolt 1.3. Can't say what did it, but the battery got hot and drained so far it would even start charging.
I got the battery charged on the old phone, and the new one, with Revolt 1.3 is working. But I'm not sure how to make sure the overheating/draining problem doesn't occur again. After 10 minutes the phone is starting to get hot again, battery is down to 57%. With the phone on or off, it does not charge the battery, even with an AC wall charger. With the phone on, it indicates 57% charge, with the phone off, the battery icon just sits at red, no charging is happening. I erased the battery stats in ClockworkMod, but is there anything else to do? Any other ideas?

It sounds like Haxid had it happen and he got back to LG stock and unrooted, all good.

Mine happened again this time totally dead battery. Trying to get some charge in it now to boot and remove cwm so I can take it to verizon.
Decrap 1.0 rom this time w/ CWM
I do not believe it is the rom. It has to be an app or hardware.

Were you having spontaneous reboots? That's when it happened to me, after a spontaneous reboot.
Good luck. Hope it all works out.

No my phone is actually super stable it just is sucking battery like its candy. Been off charger only 1 hour right now and its down to 83%. It has to be an app doing it but I have no idea which one. The phone shows 64% battery usage by android system.

When mine was hogging battery, same here. All I saw was Android process.

just to add my 2 cents here. I noticed my phone draining like crazy, I tried everything, then I changed the battery. boom. everything is now stable. I'm going to try to exchange that battery I think its my drain and reboot culprit.

[Q] OTA update to Lollipop: Terrible battery life, very slow charging

I just got the OTA update from KitKat to Lollipop (5.0.2) yesterday and I've noticed terrible battery life and very slow charging since then. My phone is always in its charger overnight and when I remove it from the charger in the morning it usually easily lasts until I put it in the charger at night again. During the daytime I do a lot of stuff on it (whatching youtube videos, listen to internet radio, whatsapp, internet browsing, making phonecalls etc).
This morning I removed it from the charger and hardly didn't do anything on it for the first two hours. When I wanted to send a whatsapp, I noticed battery had already fallen to 70% in only 4 hours or so - 4 hours of doing nothing while the phone was in energy savings mode! Half way through the day, with only some whatsapping, battery had fallen to 20%. When I connected it to the charger, it instantly dropped to 8%. After about an hour of charging, it was at 17% and said it would last another 6 hours before the phone would be fully charged. Usually I charge my phone in 1.5 - 2 hours!
When I did the update, I didn't do a factory reset and I would like to only do that as a last resort.
If I look at te battery statistics, I don't see any app using an obscene amount of battery life - the highest being Google Play services with 15%. But what I do notice is that "Cell standby" is responsible for 29% of the battery drainage.
Before I do a factory reset, anyone any tips?

This is directly from HTC tech support. To recalibrate battery and HTC charger when battery rapidly or erratically discharges, this procedure clears all battery stats, coordinates and normalizes charging.
Turn off Fast Boot in settings. Power off phone.
Plug phone into HTC wall charger and charge for two minutes or more
While charging, hold down volume up+volume down+power button and continue holding
Phone will turn on and off repeatedly every 15 seconds or so while continuing to hold all three buttons
Keep this going for 2 minutes, then release buttons WHEN THE PHONE IS ON
Now, let phone charge fully normally (with phone either on or off--doesn't matter) and battery level reporting, charging and battery life should be normalized.
Do this every month or so to keep power system healthy--even if everything seems fine. Also, don't leave phone on charger overnight for best long term battery life (according to HTC tech support: "The first thing they tell us." This is true even though charging is supposed to turn off when battery is at 100%)

Battery recalibration ... Many techs say it's a placebo. But, I will follow this manual, just in case.
I do confirm, though, that with L 5.0.2 charging takes longer, phone drains faster with the same as before apps and usage, phone is often hot, and I've started to get regular 'can't charge, your phone uses more power than available from charger'.
Re phone uses more power than available, it happens with all three original HTC chargers I have, so I have to use the charger from an Asus tablet (1.5A output).

I haven't done the recalibration thing but I did some measurements and I now know why it's charging so slowly, just not what is causing it. The phone isn't switching to high charging mode and keeps charging at around 400mA. This means that when using the phone, it's draining faster than it can charge. I also think it's not switching to standby mode causing the high drain. Often the phone gets hot when it's in my pocket (when it is supposed to be in standby mode) meaning something is still draining the battery fast.
I will do the calibration thing and see if that helps.

I just did the reset thing (holding power + vol up + vol down) for two minutes. It's now charging but I can see it's still not charging in high mode. It's still charging at only 400mA.
Edit: Phone says it wil take 10 hours to charge (it's at 30% now).

Annoying, I know, but I'd factory reset the phone just to make sure the update has 'taken' correctly

Sounds logical. How did you find it out? Instrumental, or through a phone menu?
I have checked Setings/Power. Mine says Charging on AC, which supposedly means high charging mode.
PS. Again, whatever it might mean, when I get a 'phone uses more power than..' error, I connect the phone to a 1.5A charger (compared to original HTC 1.0A) and it solves the problem. I'm not happy with this solution, though.

There are a few ways I can measure this. I have a "Charger Doctor", one of those inline USB voltage/current meters and I have an "Energy Meter" which measures wattage going out of a 110/220V socket. Both confirm each others measurements. The Charger Doctor says my phone is being charged at 5.1V at 0.4A, and the energy meter says the charger consumes about 2.5W which is about right (the charger looses some energy through heat and the Charger Doctor consumes a bit of energy as well).
But...
To be sure, I tested a few different (but identical) chargers and changing the charger made no difference. But - and here comes the strange part - I tested about 20 different USB cables and with only two my phone charged at 1.0A (which I assume is the M7's max charging current). With all the others it charged with 0.3A-0.5A. Only with those two cables it charges in high charging mode. So apparently something changed in the charger detection. Before the update I was able to charge the phone in high charging mode with other cables as well.
Also, it seems like it's now discharging not as fast as before, but I will be sure tomorrow after it has fully charged and after I've used it all day.
Edit: Yep, charging is at it's normal speed now. It's at 60% and the phone says it will be 1 hour and 1 minute until it's fully charged.
Edit2: Of the two cables it charges at 1.0A with, one is the original charger cable that came with the HTC, and the other is a cable that came with a Duracell Power Bank.

Well, after the three finger calibration, charging seems faster, and I think battery holds longer (or maybe I want to think it does, because still not sure).
One additional observation is in about 20% cases my phone is stuck during boot until I connect or disconnect the charger for a second. By connecting or disconnecting the charger, something triggers the power state and the phone boots normally.
So yes, you may be right about new power management in Android 5.
(I'm now on IC7.0.0 + ElementalX 20.0, HTC M7 Int'l))

Well, even though charging times seem normal now, it is slightly erratic. I can see the percentage making jumps up and sometimes down while charging.
Also, battery life still is very poor. Battery now lasts until halfway through the day while before it would easily last all day...
Is there a way to revert to KitKat? Other than a lot of annoyances I haven't noticed a single advantage using Lollipop.

Factory reset
I had terrible battery problems after T-Mobile upgraded my HTC One (M7) to Lollipop. The phone was constantly awake and churning with the GPS probing for a signal every few seconds. I'd lose 50% of my battery in a couple of hours. I went through the battery recalibration suggested by HTC support, but it didn't work well. Finally I did the factory reset. It worked perfectly! Now my battery life is better than ever and the phone will go well over 24 hours on a single charge with normal usage. Recovering from the factory reset was easier than I anticipated. Google Play Store remembered and reloaded all my apps automatically. The only headache was having to log in to everything again. Well worth the effort.

I did a factory reset as well and it looks like it has improved battery life. I'm still on my first day after the reset so I won't be able to really tell after I've used it for a couple of days. But like I said, the hard reset seems to have made a difference.
It has been 15 hours now since I unplugged the phone from the charger and it still has 43% left. But I just noticed a few minutes ago that two energy settings were set different than before the hard reset. Screen brightness was set to auto (when before I had set it to it's first dim setting), and data connection was set to switch off after a long period of inactivity. (while before it was set to always on). I've changed those settings and see if that makes a (big) difference.

Tested it for another day and battery life has definitely improved quite a bit but it's still nowhere near what it used to be with KitKat.

when i woke up this morning my m7 was 100% it's now 11;10 and it,s now 70%

I'm getting exactly the same problem.
HTC support said they never heard about such a problem and their conclusion is to send the phone to be repaired
I don't know how to rollback to previous version and it doesn't looks like to be a new fixed version on the way.
Or at list I haven't heard about it.

I also noticed it doesn't make much of a difference if I turn on energy savings mode.
With KitKat, my phone would easily last the whole day without energy savings mode. Now with lollipop I have to hook it up to a charger in the evening - even with energy savings mode enabled.
The thing that sucks the most is that my phone drains in alarming rate when playing a game, or listening to online radio or watching youtube videos. 30 minutes and battery drops from 100% to 50%. And the phone gets really, really hot. Before lollipop, it would drain perhaps from 100% to 85% and the phone would not heat up at all.
There are so many annoying bugs/features with lollipop, I'm considering an iPhone for the very first time ever as my next phone. Mind you, I've never been a fan of Apple stuff. But Android is just getting ridiculously bloated and simply doesn't work very well anymore. It looks like every update makes my phone less usable. And I hate the fact Google thinks it's perfectly fine to disable/remove stuff that people have come to depend on. Like my notes (amongst man other things). Google in all its wisdom has removed the Notes app making all my notes inaccessible. The only way to get my notes back is to install some third party app from the Play Store and have it transfer my notes to the cloud. First of all, I don't want a third party app handling my notes. And I most certainly don't want my notes stored in the cloud. I travel quite a bit and I don't have internet access everywhere I go, making my notes inaccessible again.

Phone powering off at 70% battery

Hi all,
My Nexus 6 GPE has been powering off after about 2 hours or so being disconnected from the charger every morning. The phone has 70% of power (going off of this last time it has happened, usually it is around 50/60%) and it goes into battery saver mode and says it is powering down. When I try and restart. sometimes it goes and instantly shuts down, other times it shows the battery is completely dead (ie the empty phone icon), with this last time I was able to get into recovery and stay on and the bootloader and in recovery it says I have 60% battery left.
This all started when I flashed the latest software (LMY47E) and the latest bootloader/radios. I used Nexus Toolkit to Factory Restore it and it is still doing the same thing, sometimes it doesn't even give warning before shutting off. Has anyone come across this before? Do you think it is software or hardware related?
Thanks for your help

Did you try this?

I did try that, it seemed to work but then turned off again. I did it about 3 more times, so far it hasn't shut off again, it was around 52% when I did it last and it came back up as 27% so I am hopeful that worked.
Has anyone else experienced issues because Qi charging? I have almost exclusively always charged this with a Qi Wireless Charger.

I have been having the same issue. Just did the "fix" from the other thread and before reboot it read 98%, after boot it says 77%. Crossing fingers.

UPDATE:
Nope, didn't work. After it went to 50%, it shut down and won't start on it's own unless it is plugged in. I'm back to step one.

I would send that phone back and get a warranty replacement.

Yep, I think that's going to be route I'm going to have to take. Damn.

That sucks. It seemed to work for me. Phone drained to 5% and automatically shut down. Charged it to full without booting, so if it still behaves, it fixed me.

Dacian like i just wrote in the other thread:
The "fix" i posted plus no more charging with Qi chargers worked for me.

I tried that, didn't use Qi charging to get it back to 100% and it still shut off. Can you use Qi charging again? I didn't spend $700 on my Nexus 6 so I couldn't use all of the features. I own 4 Qi chargers so that I didn't have to plug in my phone at all unless I was doing something through ADB.

No more Qi charging since I tried the mentioned workaround and no more problems with my N6 shutting down too early.
But I agree: not a solution if you use Qi stations a lot.

I think I'll just warranty it and if there comes a time where this starts happening again, hopefully there'll be a fix from google for it or something. Thank you for your help.

You're welcome. Good luck and keep us posted!

my phone was doing the same exact thing...first started off shutdown at 20 then 40 now 70! phoned motorola for a replacement : "sorry we cannot send replacements but we can fix it"...WTF?!?! a phone like this?! why the F would i want a repared faulty phone?!? Motorola never again never...

I have the same problem (now shutting down at 65%), i already call google for replacement but untill now i never had confirmation

I have the same problem. Nexus 6 shuts down. Displays blank white battery. Cannot be turned on without plugging into power source. Upon powering up it shows plenty of power.
Possible helpful info:
1. Recently manually updated to 5.1
2. Recently started using Qi charging
I did not notice a problem until both of those -- of the two my suspicion is the wireless charging but it's a total guess
I've tried all the suggested fixes and none worked.

Help! Battery drained, phone won't turn on, battery charging icon flashes on and off?

My phone had been working perfectly fine, as well as charging perfectly fine. Recently, I accidentally let it drop to 0%, which I don't usually do. I went to plug it into the same wall outlet as always, but instead of the usual charge process, the battery icon with the lightning bolt in the middle simply flashes on the screen and then turns off, which happens over and over again.
It should be noted as well that about 3 weeks ago my phone get fairly wet. After that incident, I turned it off till it dried, powered it up, and everything appeared to be totally ok.
Other facts:
-I can safely get into the recovery menu (power + vol down), which is stable, but any menu selections result in the Motorola splash screen for a quick second and then the phone powering down.
-The computer will recognize the connection to the phone.
Attempts to resolve:
-New cable, new usb hub, new wall outlet
-Trickle charge from the computer (same flashing)
-Phone in rice to remove moisture
-Toothbrush cleaning of Micro-usb port (suggestion from another thread)
I'm pulling my hair out, and I am considering prying off the back and replacing the battery. I have searched other threads, but have seen various solutions none of which worked for me. If anybody has any idea how I can fix this please help!!! Thanks in advance.

Either there is something wrong with your battery, or there is something wrong with the USB port. If the USB port is the problem, you can use wireless charging instead. I'm a fan of this one, personally: https://www.amazon.com/gp/product/B00S7IBDGW/ref=oh_aui_search_detailpage?ie=UTF8&psc=1.
Also, are you unlocked? If so, what battery percentage does TWRP say?

Thanks for the quick reply. It does seem like a battery problem, however it is just so coincidental that it stopped working after I let the battery drain to 0%, when only hours previously it was in use and charging without any issue at all.
Also, if there was a problem with the micro-usb port, I would think that a computer wouldnt be able to read the phone, but when I plug it in it is recognized as an ADB device.
I have another turbo with a cracked screen, I'm thinking about dissecting both and putting that battery in this phone as a replacement.
And unfortunately I am not unlocked :/.

Update
Well, after some further experimentation, I've gotten it working again. The solution was to charge it for like 5 hours, then let it sit off charge for an hour, and then it would boot... bizarre combination of actions. It has since dies twice and I've had to use this method.
It is working for now if I don't let the battery drop below like 15%. Seems more like a software or hardware issue to me, and i'm still trying to resolve it, so if anybody has any suggestions please let me know.
Also, what is the best way to re-calibrate the battery, maybe that could help?

If you can't let the battery go below a certain percentage, it might be an early sign of failure. The voltage might drop suddenly and unexpectedly towards the end of discharge, prompting the phone to emergency-shutdown.
As for calibrating the battery...it depends on who you ask. I would say that running it to shutdown (even if shutdown is "15%") and then charging it to 100% should do it, since that gives the controller a full set of data with which to extrapolate a discharge curve. Clear your cache in recovery, so hopefully the OS will pick up on this to accurately track the battery's actual state.
Get Kernel Adiutor or something similar to check your battery's health, too. If there's something obviously badly wrong, it should report something other than "Good".

If you note when your battery dies abruptly and you immediately reboot the back light is very poor. Almost flickering.
I think this is a battery issue of not being able to feed enough amperage.
...however. My phone was doing this and after a full clean reflash it has stopped. I question if this is because I am running less apps now. Or if perhaps somehow the battery managed to lose its memory. (Li ion is an odd duck..)

Thanks for the pointers. So strange, first it died at 40%, then 30% then 15%. Now, it is still dying early but I am no longer facing the issue I originally had, it will show normal charging when off, and boots up right away. Sure hope its not some ticking battery time bomb, its still a relatively new refurb.
I attempted the charge calibration so we shall see if it helps. I also did a factory reset for the hell of it, since I am on stock and can't reflash. Perhaps I'm in the clear, that would be awesome. Still no idea what the issue was in the first place though, which will annoy me to no end.

Battery 100% On, 80% Off

phone says 100% but says 80% when off charging
Tried:-
1. 2 different battery callibration apps
2. charging 100%, depleting battery. repeated process a couple of times
3. Switched to Stock (Rooted), 2 Custom ROMs (Waited till it was 100% on both on and off before flashing)
Notes:-
1. Battery seems perfectly fine (takes a while before depleting and doesnt deplete before 0%)
Currently using stock rooted

l would start with replacing the cable and charger to make sure you are getting a full charge. Then monitor the usage time on your phone over a few weeks and see if the time to empty is getting less that is a sure sign of a bad battery

Recheck with another fast charger. Generally, we cannot say if is a faulty cable or you have an faulty adapter. I hope the device chargeboard is not shot/motherboard driven related issue. Also, have you recovered the device using Samsung Kies- Emergency firmware recovery?

I did try that and surprisingly an apple charger's ETA is 2hrs
I have like 3 fast chargers and they all ETA 6hrs

I tried - original cable with original charger 6hr
- original cable with apple charger 2hr
- different cable with original charger 1.30hr
- different cable with apple charger 2hr
(Used different fast chargers too, same results)
I tried a smart switch recovery. Same conclusion which makes me think its a hardware issue

With original charger it takes 6hrs!!! Holy ****
I think its a usb port problem for sure.. Do one thing while connected to the charger go to device maintenance and open battery menu and see if it say charging via AC or USB if while us8ng the original charger it shows Chaging via USB then certainly its the port that has gone faulty..
Hit thanks if helped

Hello everyone! Though its not the right place to ask the question but I have been seeking solution to my problem from months. Long time before, my Galaxy Note II started to behave differently. Whenever I charged it completely, the phone worked normally till 75% to 80% and all of sudden a =low battery warning indication appears and phone proceeds to shut down. I tried changing ROM and calibrating the battery again but nothing worked. Finally I replaced the battery with a new one and also clean flashed another ROM in a hope to see if the problem is gone or still there. But to my surprise the problem is still intact. Now, when I turn on the phone the battery is 90% and when I keep using it, it drains normally, but as soon it reaches round about 80%, it turns off randomly. When I turn the phone back on the battery is still at the same percentage level at which is turns off. I believe there is not an issue with the battery. Please help me what to do, I am using TWRP recovery that doesn't gives the battery stats wipe option too. Should I flash a new ROM again? I would greatly appreciate if someone please helps me in sorting this problem.
What I have already done!
1. Replaced the battery
2. Changed the ROM
3. Re-calibrated the battery

I have this weird issue thats been bugging me for a while now. The phone says 100% when im on it but when i power off and charge, it says 86%.

I have noticed the same issue, I think. I suspect it is a general bug.
Guys, try charging your phone while in Android. When it reads 100%, switch off your device. Either leave the charge cable attached or reattach it after you have switched off. Now wait for the off-line charging icon to appear. Unless I'm mistaken, the percentage won't correspond with whatever your phone reports while your in Android. If Android says 100%, this will be a lower number. And off-line charging will keep on charging until you reach 100%.

Sorry for the late response. Internet finished, had to wait until the renewal date. During this time, i wiped the rom and re-installed it (Khongloi V11). Since there was no internet, i didnt sign in any accounts, Switched off the location. The phone surprisingly took 3 days before reaching 0.
Indeed, it says USB Charging 6hrs. I sometimes keep plugging and unplugging, it changes to A/C 2hrs.

I have this problem too. But I change batt_capacity_max to 1000, phone on 100% phone off 100%. If we recharge to full it will return to the same state (phone on 100, phone off ~80) so i need to change again. I don't know if this destroy my battery life ? I don't know why. I thought I'm the only 1 who have this problem? (sorry for my bad english)

I think this may be a software/firmware problem, not a problem with the battery.

I figured that was the problem but i tried it with three different roms (Khongloi V11, Final, Stock).
Maybe it's some kind of battery protection thing created when your battery is old or something?

The various ROMs may all use the same battery raportage code, which doesn't account for this discrepancy. After all, most ROMs are just fancy reskins of stock Android.
That said, maybe Samsung support can shed some light on what's going on.
On a side note? Is there anyone who reads this thread, whose reported battery charge (in percentages) is the same in Android as when the device is switched off and charging?

So... any solutions?
