[Q] shut down normally: now no power light or boot

I apologize in advance if there is a similar thread; I could not find one.
My EVO has been fine, no issues. I use it heavily every day. I'm running Cyanogen 7 nightly 147 (I think) and have been for 4 or 5 days. Using the Tiamat kernel running SMARTASS.
Last night I shut down around midnight with around 50% power. I plugged in the charger but don't remember if the charging light came on then. This morning there is no charging light and the phone won't boot. Tried long holding the power button, battery pulls, pulled the SD card (for lack of anything else to try). Nothing has had any effect.
Does anyone have other ideas? I'm at a loss. If it's dead, it sure chose a strange way to go. Any advice would be very appreciated. I need this thing for work and home. Many thanks.

Just after posting I went back to playing with different chargers and power button pushes. The white HTC logo flashed for a second and the phone vibrated but it went right back off. It's the first sign of life I've seen, but I can't get it to repeat or go further.

This happened to my sisters Evo when she first got it last summer. Luckily it was the battery and HTC shipped a new one for free. The warranty on the evo is 15 months so you can try and request a new battery!

I have found one similar thread: http://forum.xda-developers.com/showthread.php?t=913258. So maybe it is a dead battery. Been getting amazing life recently, so it seems crazy that it would suddenly be dead. Is this common?

Any suggestions for going to the Sprint store with a rooted phone? Since it's a bad battery, they may not need to look at the phone once it boots. I haven't had to do this before, so I'm not sure what to expect.

if you do go to a sprint store, i would not let them keep the phone or even take it out of your sight. if that happens you may well find yourself unrooted. but thats just a guess. you can get on ebay or any other similar site and buy a cheap battery for less than $5. then if thats not the problem go from there. this same problem happened to me but luckily one of my friends also has an EVO so i just used his battery and my phone worked great. so i just bought a new battery

Thanks for the input. Headed to the Sprint store in a minute to see if a battery will solve it.

It was the battery. They tested in at the Sprint store and pronounced it DOA. They said they don't normally have spare batteries but they happened to have one, luckily. I was pretty grabby with the phone and didn't let it go for long. Once it started to boot I took it back and they never saw the Cyanogen screens.
Overall they handled it very well. I was impressed with how responsive they were. I was out of there in 10 minutes.

Battery

Battery on my Note 4 has always been great but as I'm just about at the 1 year mark of owning the device the battery has been dying faster and now in the last week when it gets to 25% it suddenly drops to 9% and I get a low battery warning, then less than a minute later it shuts off and when you plug it in it shows 0%.
Genuine Samsung replacement batteries are only 24.99 on their site so not a big deal but I'm just wondering if anyone else is seeing this at the 1 year mark.

You may have overlooked by title but root cause was localized to degrading battery capacity.

2nd edit: the theory was raised that the battery degrading is being prematurely induced by leaving the phone plugged in overnight. My battery appears to be going strong but I've rarely left it plugged in for extended periods of time; minutes as opposed to hours after fully charged.

Type secret code *#0228# in the keypad (press quickstart 5-7 times, the screen will lock after pressing, but don't worry, unlock the screen and press until 5-7 times) and charge your phone fully. The problem will solve !

I noticed similar degradation a few weeks ago. So I bought a Mugen 8k battery. Problem solved. I now get over 12 hours SOT.

Damn man this was a great idea. My phone has been freezing and randomly restarting and getting extremely hot. Last night my battery went from 100% after a full charge down to 0 when I woke up. I was getting read to do a factory reset and thought I would try this and I think it really fixed it. So far so good anyway. Thanks!

You can flash AEL Kernel to last your battery better. Flash via recovery. Link download at echoerom.com, 7.8 is the lastest version.

Yeah I was thinking of that but in January I'm due for an upgrade and I plan on trading this in so I'm keeping it stock for now. I'm looking at the S7 maybe as my next phone. That's a BIG maybe though. We'll see what they come up with but it sounds promising.

Not me. I've heard of other people with the same experience of getting only one reliable year out of a battery, but my original Galaxy S3 battery only just died a couple weeks ago. That's 3 years, I think, of reliable usage. Your mileage may vary, I guess.

I had the same problem with my Note 4. I got a Samsung replacement battery through best buy and it did the exact same thing at first but it seems to have "learned" that the new battery will last longer.
Now if only these rapid updates that sprint is pushing out will stop trashing my phone

Replacement Battery issues

Hey all...
I recently had to replace my Note 4 battery and have found that the battery is not available... It's been replaced with a different part number. The old one is EB-BN910BBU while the new one has been marked EB-BN910BBE...
What's the real difference? I have been struggling with charging it fully as well... Stops right around 89%. I have factory reset to see how it goes but with the new battery it seems to drain awfully quick.
Has anyone else had any issues with finding batteries? OR does anyone know what the difference in the batteries is?
Thanks!

i have 2 original samsung note 4 battery, both are EB-BN910BBE and they have no problems giving me expected battery lifes. you can try reset the fuel gauge by entering *#0228# in dialer and then press quick start, after the phone lids up you charge the phone until 100% and leave it for sometime.. hope it works.

What does resetting the fuel gauge even do? That doesn't make entire sense to me... does it just re-calibrate it?

Yes both the new batteries I got are OEM. I have tried to charge the two new batteries to 100% but they don't want to fully charge. I've factory reset my phone and wiped the cache... still no dice. But then the question about the differences between the batteries comes up... IS there a difference between the U battery (which is the old stock battery from when I got the phone) and the E battery (which is the new replacement OEM one...)

I was personally told by Samsung that the U and E are region codes for the batteries designed for different models of the phone. They went further to tell me that getting a battery for a different region phone would have unpredictable and possibly bad results if used in a U.S. branded (U) phone.
The true differences I have no clue and have just started looking this true difference due to my battery is now failing and it is a U battery. Some things I have uncovered is the E variant is suppose to be superior to the U variant however, I keep seeing a pattern for those with 'older' U.S. Note 4s, particularly the AT&T models with poor performance from the E batteries. If it is simply bad luck or actual truth I have no clue. Still looking.

I had the issue buying 3 of the E version on ebay not knowing any difference from china. They worked fine for 6 months then completely died. noticing the original battery was U version and still working I found this link. I can confirm the phone occasionally reboot for no reason about 3 months into using them but since the phone is a couple years old I did not really suspect the batteries at the time.

1. Batteries wear out (slowly) sitting on the shelf. Buying demonstrably NEWly manufactured batteries would be in my opinion the trick to successful battery replacement. Maybe this is a problem for the obsolete Note 4. Bought a "new" battery today... Ad says OEM but is it going to be? And will it have been on a shelf for the past 4 years? Maybe. I will see.
2. Charger issue on an old phone? I do not know about this if it is an issue or not.

10-20% (+/-) battery drop after a reboot

I've already tried doing a battery calibration as recommended by many people on the V20 threads, buts this is still happening to me. If I reboot my phone, when the phone comes back on, my battery level has dropped 10-20% (give or take). I know reboots can consume battery, but this is quite a large consumption.
Last night, for example, my battery was at 60%, but after I rebooted, I was immediately at 25%.
Again, I've down the whole calibration thing at least 5x now, and it hasn't helped with this. So now I'm wondering:
1) Is anyone else having this issue, especially with the same variant as me (see below)
2) Is this a Nougat 7.0 issue
3) Is this a battery (hardware) problem. I ordered one of the spare battery kits that come with an extra battery. I figured that I'd try the new battery, but if it doesn't help, then I have a second battery anyway.
ATT variant (h910)
Running on ATT
Battery life has been mediocre to poor, and I've disabled so many features by now that it's gotten kinda ridiculous.

Yeah, I didn't think it was normal. I was hoping it was a Nougat 7.0 issue, but I wasn't hearing anyone else with this issue. And as stated too, my battery life hasn't been great. I make it through the day, but only of the phone isn't used much. Otherwise, the battery will drain pretty fast.

What was your calibration method? Running it down to zero once should be good enough then charge with phone on or off without using it to 100%. If still doing it try your other battery. If still doing it exchange.

I pretty much did as you just said.
I ran the battery down until the phone powered off. Then I kept attempting to power it on until the LG logo stopped showing up and the phone said that there wasn't enough power to turn on. Then I charged the phone to 100% while phone was still off. Once it hit 100%, I left it charging for another 2 hours.
Overall, it helped, but once I reboot the phone, the battery always drops quite a bit as stated in my first post.

Do you have twrp intalled? I think Lg has a problem with it's battery stats because of the removable battery. On my v10 I had two spare batteries. When one got to like 4% I would power down and pop in the new one. When back on it would read the battery at like 19% or something to the liking. I had to leave my phone off for about 30 secs between changes. I was having similar issues to what you're describing with my v20. I ended up formatting data in twrp and then set my phone up old school style with manual app installation and no data transfer whatsoever. I let the phone die completely and then charged while on uninterrupted. I then at 100% unplugged it and plugged it back in for 20 minutes. My battery has been perfect since. I would also note similar issues on the G4 too. I think this is the cause for the notorious Lg bootloop.. My G4 did it right before the battery drained out and so did my V10..

I had that problem on an old note 4. But not a drastic a jump in percentage. Brought it to Samsung and they just changed the battery and the problem went away.

I have the ATT V20, which doesn't have the bootloader unlocked. So, no TWRP.

I heard similar issues when I had my Note 4, but in this (using a new Android OS that not many other phones have yet), I wasn't sure if this was hardware or software. I really hope the second battery fixes the problem!

I'd rather not since I don't have the time to re-setup all the programs I need for work. It takes several days to get everything up and running again, and after having to do this 2x already this past month thanks to the Note7, I don't want to go through it all AGAIN. Its too much of a hassle and shouldn't be necessary since this is a new phone. I mean, w y reset a new phone that's only a couple weeks old?

Motorola Droid Turbo 2 Shutdown,Battery Drain after Nougat update!

My phone is shutting down frequently and battery drain is so high.
Can I downgrade to marshmallow? or even fix these problems by any means?
Help!!

Same here. Battery has been draining like hell. Phone dies on me at work most days,with medium usage.
If anyone has got a fix, please feel free to let us know.
Thanks

I literally can't use my phone.
Almost everytime I open an app, camera or anything the phone shuts down immediately

I had the same problems. Ended up contacting Motorola and got a replacement.
Still not as reliable as original on Marshmallow.

Hello everyone, here is what I've done thus far. . .
Factory reset the phone and allowed all items to sync back over from Gmail
Factory reset the phone and DID not sync back over from Gmail
Ran phone in safe mode
Allowed battery to fully drain, then fully recharged using an OEM charger (battery lasted about 26 hours with very minimal usage)
Fully disassembled and reassembled the phone
Contacted Motorola Support (if phone is out-of-warranty, it'll cost you $100 or $125 for a USED REPLACEMENT of an ALREADY OLD PHONE)
Contacted Verizon Support (waste of time -- they just want you to upgrade of course!)
Cleared cached partition in Recovery mode
Attempted rolling back to Android 6.0 (FYI: you can't -- Bootloader is locked -- don't waste your time like me lol)
At this point, at least in my situation, I feel like the problem has something to do with the Battery and some type of "check" that is done when applications are opened. After I fully disassembled and reassembled my phone, I did not have the random reboot issue whatsoever.. UNTIL.. I used a non-OEM charger. After that, I had about 2-3 of the random shut downs that required the phone be plugged into a charger to start back up. At this moment, the phone hasn't had the random reboots since removing it from a non-OEM charger, but I will continue to investigate.
I planned on replacing the battery as well if the problems persisted. Really sucks that nobody in Motorola is willing to help their customers. I have probably spent upwards to 10 hours troubleshooting this issue and trying to find a root cause, but I'm not a mobile phone professional. If you contact Motorola, they just think $$$ and tell you to send in for a replacement instead of resolving the ROOT CAUSE. That ensures the DT2 to be my final Motorola purchase for a very long time.

Will try that
I hope it works, I really do
Because I can't basically use my phone outside because when it turns off I have to turn it on using a charger!!

I have corrected this problem in my Verizon Turbo 2, the fix is to buy and install a new battery.
My own phone gradually lost it's charge capacity, it would deplete rapidly, then it wouldn't power on except on charger, then it wouldn't power on at all.
Funny thing, this problem is on multiple forums with no fix.
I tried, factory reset multiple times lost all kinds of important texts and memos.
Then I changed the battery from here:
ebay: search " New Replace Battery for Motorola Turbo 2 XT1585 Moto X XT1581 SNN5958A FB55 -USA "
I would say it is an extremely easy swap. Just have to heat up the back rubber with a hairdryer to release it, or not! (I didn't, I slowly peeled mine)

I had assumed it was a battery issue myself. I just now replaced my battery as well, so I will see if my problems resolve. $20 for a replacement battery > buying a new phone, that's for sure!

Got mine fixed by changing my charger. In my case my charger was the issue. Yes it's the charger that came with the phone.
I swapped out chargers with my girlfriend,she uses nexus 6. So far the nexus charger has worked magic

Has the battery replacement fixed your issues permanently? Were you getting fast battery drain, or having random shutdown problems?

Sorry for delays! Yes, this has absolutely resolved my problems. I bought my replacement battery off of eBay and I have not had random shut downs or fast battery drain. I will say the battery life isn't as good as a brand new device (from the manufacturer), but it's a barely noticeable difference in battery life.
