Hey... How old is your phone? Your battery has likely degraded over time?!
Downgrading won't fix your issue. I am on 7.1.1 and don't have any issue regarding battery, though of course, the battery life is not as good as it used to when the phone was brand new, but I guess that's normal...

Wow... 1 year only. Are you sure the phone was brand new and not a refurbished unit? It's strange it shuts down so early. You could try installing "AccuBattery" from the playstore and let it run a few full charges. It will give you an approximative estimation of your battery capacity based on the original capacity versus its actual capacity. Your symptoms in my own opinion is a sign of an early degraded battery. It can happen. Though I haven't really seen this on the N6. I'd try to look for an oem battery and replace it myself, it's easy on the N6.
If you still want to downgrade, backup your internal storage first, because you'll have to unlock the bootloader and it will wow the whole data partition. Flashing an older bootloader, at least downgrading to 5.x may brick your device. I don't know for 7.x > 6.x, but I don't recommend it. Anyway, just flash system.img with fastboot once your bootloader is unlocked. Go in recovery and do a factory reset and you should be good to restart with 6.x Android.
Hoping you'll solve your issue either way... :good:

My bad. I switch between N6 and N6P forum and really thought I was replying to a question in the N6 Q/A forum.
Ok, it's a known issue. People have this problem running 6.x and 7.x.
Since your phone is just 1 year and 2 months old, try to RMA... Sadly, except replacing your battery it's the only option. Some users out of warranty have .Anaged to get a replacement since it's a widespread issue. Have you seen the thread here: https://forum.xda-developers.com/nexus-6p/general/nexus-6p-randomly-shutting-50-youre-t3522911
Sorry for having kind of missguided in the first place.
Good luck...

The early shutdown issue is well known but not the fast discharge after unplugging. At least I've never heard of that being a known issue. I would take the previous poster's advice and install AccuBattery to check your battery health. Some people have definitely experienced a badly degraded battery on the 6P after a year and either RMAd their phone or replaced the battery. Huawei did extend the warranty on the 6P so you might still be able to get RMA or warranty service at a local repair shop. Good luck.

Ordered G2, Clarification needed: Root, Flashing, Unroot. Oh, and battery :)

Okay, i apologize but i ordered this device after having tested my friend's LG g2 device running stock. From a Nexus 4 , i find this is a big upgrade. ESPECIALLY THE BATTERY!
1.when I root a device and flash custom recovery, can you unroot the phone all the way back to STOCK erasing all traces that you've flashed / tampered with your device?
2.I'm a bit confused, i see d801/d802/d803, this makes me very confused, all i see are american providers listed, what does this mean for people living in europe? In my case, more specificially, Austria(also with provider)? This leaves me a bit worried and confused because i ordered it on contract - what does this mean for me? Would I still be able to flash my phone without a problem?
3. Flashing: What is flashing like in this device? Good ol' nexus 4 style
wipe data factory reset
wipe cache/dalvik - flash rom + gapps?
Or like the htc one x (fastboot erase cache... bla bla bla)
4. Has this phone come with any particular problems or is there something i should look out for when i recieve my phone? if yes ? What?
5. Firmware: As i've mentioned above i've got a provider, can i turn my smartphone to a sim free version of the phone or is this not doable?i.e: can you switch between firmwares without a problem?
6. And finally, how easily can you replace the battery on this baby? I've seen a youtube video of a person disassembling the back cover, however, he sadly didn't remove the battery like i had hoped he would do. The back cover at least seems easy to take off, so i'm relieved.
Thanks for taking your time to read and answer my question, i'm really looking forward to this device, it's gorgeous. To me the nexus 5 would have won if it were not for it's horrible battery. In fact, maybe not, this lg g2 device offers SO much without a stock rom and that's something to respect, and knowing that i'll be able to flash google's STOCK rom without a problem would make me be able to experience the best of both worlds.
I wish you all a happy new year
Thanks in advance
Hi,
1. Yes, look in the general forum.
2. It exist different models, for europe you will get the D802.
3. Just Data/Cache/Dalvik for the most roms.
4. Don´t know, same with other phones
5. I didnt research about this, but i think it´s not easy to replace the battery.

How can I go from Unlocked bootloader/B20_Boot back to locked bootloader/B20?

Looks like I have to return my phone to ZTE because a hardware issue has appeared. It doesn't always charge when I plug it in and it never does quick charge 3.0 (Always says to connect original charger to charge faster even with the original charger). Never deep sleeps either.
I used B20_Boot method to unlock bootloader and am I little nervous about sending it back to them in this state. Any ideas guys?
Thanks.

Thanks for the response man, I really appreciate it.
I am pretty paranoid that eventually I won't be able to charge my phone as it seems to be getting worse. If there isn't a way to do it now I guess I'll just send it back in this state. Not like I opted out of any warranty.

Have you try Factory Reset or Wipe Data-Cache-Dalvik from TWRP?
The update will be ready this week , I hope so you can just little longer but try the above.

I should have said yeah I did try factory reset. I think physically something with the charger port went bad. I was in recovery and the charger wasn't working. So weird.

Hey man I am quoting you so maybe you will notice. You seem pretty knowledgeable about this. Is there a img (twrp backup maybe?) of a working system partition for B20_boot? The final thing I can check is to reflash that and take out all the stuff that root and xposed did.

You should be able to find it in this post, it's a full system image, so unzip and flash with TWRP

There is also a possibility that the charger or cable went bad, only way to know for sure would be with another pair. BTW there is a way to go back to stock to the point that old OTA will flash, see

Intermittent charge(Help!!)

Hello, I'm so sorry for annoying you, but I'm having an intermittent charge when charging the phone, I don't understand why, I haven't dropped the phone or something related with poor care. I plug the charger to the phone, it appears charging but suddenly it stops charging, it happens with all the Roms, even with the stock. I have to disconnect and reconnect the charger to continue, it's randomly. Thanks in advance.
Maybe the cable or the charger have some issues? Try another one.

Oh sorry but I didn't specify, I have tried with a Samsung charger, LG charger and others, even with the USB port from PC.
I had this issue. Also had a weird issue if unusual battery drain. I had to send it back to Motorola to get a battery replacement. Just came back yesterday and has been fine. I do not recommend the turbo charger in my opinion. Moto support told me not to use it...

Okey thanks, I have cm14.1 and TWRP, I have a TWRP backup, it's necessary to return to stock? Like flash stock recovery and restore the stock rom with the backup? Also I flashed ElementalX kernel, then I returned to stock kernel but now on the bootloader says "firmware status: modified", obviously I don't have warranty, the question is, Would Motorola repair the cellphone?

I do not recommend this but this is what I did. I did a restore using fastboot. I also did the overwrite of the boot logo using fastboot. I did the online warranty thing about unusual battery drain. They gave me an email with a prepaid FedEx label to send it to them. Once it was received I did online chat daily and nagged about what's the status of it. All I know is I got it back and it was still unlocked and appears to have been reset because it was back to the black screen. So far I haven't had any problems the last couple days.

fix battery dies at 30% or less for moto x 2nd

halloo
i bought an used moto x at&t 16
and i found this issue power off at 30% or less and when ever device off and then power on you find that battery show percentage more than it was
wrong percentage...
so if you follow this steps i think it will help you to fix the problem
1) charge to full 100%
2)then download this app called "repair battery life pro" and .... its totally free
3) start the app
4)after it finishes
5)download battery calibration and run it ...also free and dont need root
this how i fixed my problem and i get full day with it ...also when the battery hit 15% run the battery saver app
try this steps i hope it will work with you and give me ur feedback
I will try!
Hope this will work, I'll let you all know. The problem is that my phone has been charging for almost 4 hours and still stuck at 83%. I'll wait till tomorrow to see what happens.
Current Phone
Moto X2 2014 - Unlocked ( NO CARRIER) | XT1095
32GB Model ROOTED

The battery problem has been happening to since 4 months ago.
This was strange to me as I remember a couple of years back when I had a HTC Evo 4G it lasted a lifetime until it finally gave in to human error; bricked via bad flashing.

Dont work for me, my phone turn off at 10%
I can confirmed that this didn't work for me, looks like replacing the battery is the only option you have.

did you clear the cash from recovery and turn on the saver on 15%
Clear the cash and run saver at 15 percent
Okay, here's the basic fix (assuming your battery isn't broken)
1. Run your phone until it turns off.
2. While off, recharge phone for 8 hours or overnight
3. While still plugged in, completely boot phone.
4. repeat within 48 hours.
Hold power button down for 8 seconds through out the day to get it to restart with correct battery level and do the same during charge.
just flash the cypher os rom , do clean flashing and then calibrate your battery , after that go for error checking in your battery i swear that battery will never die on 30% or 10% it will completely die on 1%
click thanks button if it works for you people
didn't work here too
Changing my rom from stock rom to custom rom (I use resurrection remix rom) solved this battery issue. My battery always dead on < 1% and never had random shutdown on 30% or such as.

My battery now also dies at 1% but usually jumps from 30% to 1% in 5 seconds xD

Maybe a little off topic but it has to do with the battery. I just bought a wireless charging receiver patch and it works great. However, I noticed it only charges up to 80 percent. But, when I plug in the stock charger it goes from 80 to 100 percent in like a minute? I dont know if it is a battery calibration thing or the fact that the Moto X was never meant to wireless charge and it confused the phone?
Potiential fix!!!
i'm testing a really good theory out on my XT1097 (ATT) running the latest nightly of Lineage.
most people end up unlocking the bootloader with from 4.4.4 - 5.1. this is bundled with a bootloader from 2014/15. this got me thinking, can't i just flash the bootloader from a 6.0 OTA and see if the battery percentage matches perfectly with the OS? after initially flashing the latest possible bootloader (for me, version 61.00, built on 20160824), this actually mirrors the battery percentage of TWRP and when booted into android, and even off-mode charging matches perfectly when booted into android.
i'm going to run this for a week and see if i get any more weird battery reboots at 20-15%, since i know it's not a hardware issue on my end after tediously doing a battery swap on my XT1097.
for those who WANT to try this out right now, grab a copy of a 6.0 OTA for the XT1097 (IF YOU HAVE THE XT1097), doesn't matter what carrier as long as you use the correct zip for the correct model. extract "motoboot.img" and flash it with fastboot.
stock OTAs for XT1097
Code:
fastboot flash motoboot motoboot.img
fastboot reboot-bootloader
this may fix the bug for most users, i'll check in every day or so if there's any problems.
Would this work on a XT1096 Verizon? It never officially received marshmallow 6.0 in the US. Will a XT1097 boot loader flash on the XT1096 without bricking it?

looks like the xt1096 people may be out of luck, since it uses it's own hardware compared to the xt1097. my guess on why this battery issue is happening is because of the fact that the bootloader is designed to talk with the original android version that it supports, which is usually 5.0 and below. until verizon puts out a 6.0 image or if some brave soul decides to fix the bootloader, you're out of luck.
so far my battery issues are minimized to a point where it hiccups once in a blue moon and shuts down, but haven't had a need to bring out my backup battery to get it to boot again. for anyone with the xt1097, my problems have been substantially fixed.
I always thought that the system was having an issue communicating the proper voltage / battery percentage to the updated ROM. Would be nice to see someone fix this! I may actually get rid of the phone because of this annoyance. Its nice to know when your phone will die!

the price we pay for the bleeding edge . i'm really happy with this phone and i probably won't get a new one until this one blows up or something, so hopefully someone figures it out for the verizon folks.

Nexus 6P BOOTLOOP after using Facebook

1 hour ago, I was checking Facebook, and a moment later, my phone started to restart... After a few moments, I realized that my phone was in bootloop. I tried booting into recovery, but It started a bootloop again. Flashed TWRP, nothing happens, still bootloop. Flashed vendor, system, boot, cache, recovery, radio, bootloader from lastest factory image. I have very important data on my phone, so the last thing I want to do is to do a factory reset. But I still hope that I can somehow get the userdata partition from bootloader or somehow make it boot. Can you help me? The only thing I can open right now is bootloader.
I'm having an exactly the same problem with you.
The only difference is that I didn't use Facebook.
I dared to lose my every data so I formatted userdata partition of my phone and flashed stock image, but it didn't fix mine.
I failed at figuring out the solution yet, but there's still one hope.
When I contacted with huawei, they said there's an upcoming update, and it will fix bricked phones.
I don't know if it will work, but considering you had your bootloader unlocked and can access it, and you have some important datas that you don't wanna lose, I recommend you keep your phone until the update gets released, then manually flash it without wiping your user data.
Given our phone's symptom is exactly the same and you tried similar methods I've tried, this is the best way I think you can try.
Good luck. You're in the same boat with me.

Yes, but we can wait for this update for months.. Also, when you flash a factory image, you lose you data (correct me if I'm wrong). So, it doesn't matter to me, if I try to format user data, or wait for the update. Hm...

Well, android 7.1.2 beta for nexus 5x, pixel, or etc was released a few days ago, and for nexus 6p, it'll be released soon.
This is just my imagination, but maybe they're taking some times fixing boot loop so the release for 6p is getting late.
Also, you can flash factory images without user data lose by manually flashing it using fastboot commands.
The released image will contain some .img files, then you can extract it and then only flash required files without formatting userdata partition.
Don't use flash-all.bat, and use fastboot commands to selectively install image files except for userdata.

Right! I've just got an idea to try older factory image versions for Nexus 6P... Mabye I get it working . I will let you now
I'm on the same boat as both of you guys. I tried installing TWRP but it continues to bootloop.

I'm on the same boat as both of you guys. I tried installing TWRP but it continues to bootloop.

Well, android 7.1.2 beta for nexus 5x, pixel, or etc was released a few days ago, and for nexus 6p, it'll be released soon.
This is just my imagination, but maybe they're taking some times fixing boot loop so the release for 6p is getting late.
Also, you can flash factory images without user data lose by manually flashing it using fastboot commands.
The released image will contain some .img files, then you can extract it and then only flash required files without formatting userdata partition.
Don't use flash-all.bat, and use fastboot commands to selectively install image files except for userdata.

Guys, did you manage to fix it? I was doing some research, talking to some persons, and they said that it is probably a hardware problem. So, I went to the nearest Huawai servis, and they told me, that if the problem is really on hardware, it will cost me around 340€ (363 dollars) to replace motherboard... I can't afford that much... Its is almost a price of a new phone. I hope you came up with some better solutions.

For now, I failed.
New 7.1.1 minor build update didn't fix my phone.
And google said they can't assure there will be update that will fix my phone.
I'm waiting for 7.1.2 beta, and if that doesn't work, well.. I don't know.
Maybe I should await 7.1.2 official, or.. just give up everything.
My hope is getting faded, and yeah.. for now, I can do nothing but wait for update.
Actually, I don't think those updates will work.
I'm just giving it a last chance, since repair service at here also costs about 350$, and if I fail, I should keep using Nexus 5.
Ah... It didn't took 2 weeks for my phone to be bricked after I bought this phone.
I really want to get this phone back, but the hope is too faint.

Exactly... I was thinking... What if we lock the bootloader and send the phone to repair service with warranty papers... Do you think that can actually work out? Can they see that the phone was rooted, if we lock the bootloader with ADB Shell?

I live in South Korea and in my country, they provide repair by post service for devices in the warranty period.
For me, my warranty is expired, so I had to bring it to the service center myself.
I've locked the bootloader and brought it the center.
They didn't check if it was ever unlocked or rooted.
The engineer only tried rebooting my phone several times, and said he should replace the motherboard. And they said they couldn't fix it for free because the warranty is expired.
I don't know how Huawei in your country will handle it, but I think if you flash the stock image and lock your phone, maybe they won't see that was ever rooted.
But I also don't know if they will provide free repair.
No luck on my end. I tried everything... I've been flashing and repairing problems like these since the nexus one but I'm totally stumped. Lucky/Unlucky for me I've only had the device for 3 months so I have an RMA ready since it is under warranty.
Most importantly tho is that I want to recover the files on the device which will not happen if I take it to the repair center as they reflash all the devices before proceeding to fix it.
I tried getting TWRP but the device reboots back into the boot as soon as I select recovery.
Also tried flashing everything but user data using flashboot and the nexus 6 .img files but still in the same situation.
I just wished they would've at least added a microsd option so I could at least have some of my files back...
I don't think I will ever get a phone without microsd option again or root and unlock bootloader on every device I get. This was the first phone I decided not to mess around with since everyone kept telling me to enjoy the stock experience....
Worse experience to date with android.
Well I gave up trying to fix it by software, and found another solution.
My warranty is expired, so it wasn't cost-efficient to bring my phone to official service center.
Now I bought a display-broken phone at about 60 dollars.
Gonna bring it to an engineer and replace my phone's motherboard with its intact one.

It seems like you're Korean like me.
I bought it from Naver Cafe Google Reference Nexus Forum's market.
And yeah. It's H1512.
No, i'm not Korean but I spent a couple of years working in Okpo and Ulsan on several projects. There is a guy from KL in another thread looking for an H1512 motherboard. I'll pass your info on to him. Thanks.

It was a one-off purchase of a broken phone on a Korean market equivalent of Craigslist. You'll have to dig around and find one locally... and be lucky, too.
I just had reboots today for the first lasting about 20 minutes. I was able to get into Recovery and clear the cache and then shut down the phone. Upon restart it looped a few times and then fully booted (thankfully). I have placed the latest firmware in the phone in the hope that if this happens again I can flash the firmware and access the phone.
I hope this helps a bit.
I am rooted and running N2G47H.

Hopefully it will but realistically this could be the beginning of the end for your phone given the 6P history with the boot loop of death. Presumably your phone is out of warranty?
