Have you tried to delete your batterystats.bin to recalibrate your devices battery?

For me it sounds weird, I have also an old battery but luckily I have not this problems at all.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] olus:
no, last time i need to do things like this 7 years ago..

a few users confirmed this problem with flickering cam and then shutting down when battery is under 50% a few weeks ago here in this thread with this rom.

so i thought its a bug and not my battery.

will look for this posts and ask this users if they still have this problem.

thanks!

[MENTION=7802728]atakan33[/MENTION] what shutdown and crash problems you had?

edit:here it is, 2 users confirm this "under 50% bug". one has done all battery calibration things:https://xdaforums.com/showthread.php?p=77779078

i am using this rom with b12 bootstack.I flashed magisk 18.1 with swifty kernel,but i had to reboot like 5 times for magisk to show up.Then when i open magisk its asking if i want to upgrade to full magisk.Whats up with this? Magisk developer says we need to flash custom kernel after magisk,but others say we flash magik after custom kernel...what are the right steps? I always flash custom after magisk

I did a dirty flash of OrdenKrieger's latest posted build over LOS 5.1 Official with OpenGapps nano and Magisk with Props, after 25 hours of up time my phone seems to be working without any surprises.

Power usage seems normal, GPS seems accurate enough for a drone strike, it clicks in and out of airplane mode no problem, and no crashes thus far.

My online banking works for me, the phone phones in and out, that's important stuff to me.

Thanks for doing this OrdenKrieger, especially since you are no longer normally running the hardware, a lot of us still are and really appreciate this.

How is my kernel going so far ? Same sudden shutdown as you described before?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] olus:
its good so far, many thanks!

i wasnt under 50% today, recharged few times because i need my phone at this evening. i will see next days..
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Choose an username...:
i'll tell you what we know, do what you want with this... Let's not get into drama again though

Your phone shuts down when you snap a photo because your battery has high internal resistance (i.e. degraded) - GCam's HDR+ processing takes up 100% of your CPU (check the usage and frequencies when you snap a picture) and therefore sets your cores to 1593/2150 MHz for as long as the processing takes. This makes the phone use about 1.5A from the battery --> high battery ESR provokes a drop in voltage --> BMS (battery manager) sees the drop to <3.2V and turns your phone off. A telltale sign of high ESR is the shutdowns, but also the battery heating up when you charge it or use it heavily - the (equivalent, theoretical) series resistance dissipates a bunch of power whenever high currents circulate through the battery

At least use Accubattery to get an estimate of your battery health, this should only happen below 30% if your battery is pretty dinged up but if you are getting it with 50% then it must be below 2500 mAh? Of course a charge meter would be ideal to know how much capacity your battery has, but unless you have one you are way better off just buying a new battery

Plus if you were going to calibrate the battery, deleting batterystats is pretty useless. The accepted method is by using bms parameters but it doesn't work in custom ROMs in the axon, missing files.

I checked the link that you posted at the end and I think he's talking about the fuel gauge bug, i.e. LOS always showing 50% battery, which is an entirely different thing
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] olus:
i tell you what ive done, do what you want with this.. lets not get into drama again though.

because of your post i ordered a new battery. i will receive it next week, than i will report if or not this is still happening. thank you!

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] blu3wh0:
So I think all of my crashing to the red light and random reboots were due to having an SD card inserted (1-2 times per day). It does not matter which card I use, the result is the same. I don't think there are any problems with the microSD cards either. Taking it out, I have not gotten any hard crashes so far, but do get the infrequent soft reboot. Does anyone with a microSD inserted have no issues with LOS 16?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] CSRoad:
I'm not having problems, but my microSD card is only 16GB, maybe size does matter. (-;

IIRC it is formatted as FAT32 an used as storage.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] olus:
i have a microsd card.. no crashing with red light with newest build and kings kernel.

i also have a 16gb card, dont know format, think fat.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] RedWave31:
No problems with a 64Gb Sandisk Extreme and the latest LOS 16.0/2019-03 dirty flashed withtout anything else (no custom kernel, etc).

As stated before, check out your battery health.

Try reducing the CPU to "normal" (or "speedy" without going up to "performance") to see if high CPU usage (and high battery drain) is your issue.

- If so, replace your battery if possible.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] blu3wh0:
I'm using a samsung u3 128GB formatted in exFat. I'm not sure what the battery/CPU performance has to do with this unless it uses much more CPU with a microSD in since it has not crashed once with the only change being the microSD removed (+accubattery installed). I never go below 50% battery either with the usage cycle I go through.

However, I've noticed my battery charging is much better heat controlled recently. I did install accubattery and am on the 136 build of the kernel from the other thread. The kernel itself did not help, but it is what I stayed on. My battery used to heat up a lot when charging and using Waze etc. at the same, while now I can tell it significantly throttles charging current to maintain temperature. I haven't gone through too many charging cycles so far, but battery health is at 77%, although the phone still lasts me through the day. Not surprised as the phone is reaching 3 years old soon, but I don't have any plans to replace the battery.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] king1990:
So do you still have crashes even with the updated kernel ?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] blu3wh0:
I still had crashes for the day or so that I used your kernel with the microSD installed. It's still my kernel with no microSD and I don't have crashes anymore. I need to actually go back and test what actually helped and what didn't, but I'm happy in the current config except for my inability to use my microSD. It may have been your kernel that helped, but needed time to settle, but at this point I don't know. Regardless, thank you for your work! I'll let you know if I find time to test.

Hi all, does anyone know how to fix the bad GPS reception / sattelite lock? Is it due to A-GPS? Or something with the antenna? Seems that the GSI ROMs are not suffering from this bug. Thanks.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] apokolok:
Why fix a software problem with hardware measures?

The 'boot to red dot' only occurs in LOS 16.

If it is voltage related, it still is a software problem.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] RedWave31:
That's because you're unaware that previous kernel problems and spontaneous reboots were hardware related and software-dependant.

I'm NOT talking about booting to red dot (I've never heard of that beside it being the normal fastboot state with screen off). Since that's probably Fastboot, why call it that?

I'm talking about the random reboots. I won't explain again the battery thing, you can search about that, it worked for some.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] apokolok:
I use this phone for nearly two years now.

I've had at least 10 different ROMs, one of them was LOS16.

This was the only one that had the boot to red dot problem.

Never had it before, never had it after I changed to Liquid Remix some months ago.

So please stop advising to change the battery, it's a ROM problem, not a battery problem.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] RedWave31:
So... When you boot to red dot and your phone is connected to your computer, you're telling me that nothing is appearing in the peripherals, uhm....?

And I persist that the random reboots are due to the kernel being too heavy on your CPU and your battery not being able to provide enough voltage.

I'll stop writing, please don't quote me again, thanks.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] runninghamster:
If the phone is connected to the computer after the red light, and in Device Manager it shows up with DFU, that means the problem is completely software related.

Whilst having random reboots could be due to a sudden drop in voltage from a degraded battery, it's not always the case. I would recommend checking all software problems/solutions before blaming a bad battery. IF however the battery has NOT been replaced in more than 2 years, or has been degraded from daily use, then it is most likely a battery issue.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] olus:
yesterday i got my new genuine zte battery. i replaced it last night. after booting up, it shows 50%. one hour later, it still shows 50%. i charged for a while.. stuck at 50%.

i drained the battery till phone turned off and tried to charge full when it turned off, but it dont let me charge turned off, because the device always boots up when charging. tried deleting batterystats.bin, no luck.

is this the "battery stuck at 50% in los16"-bug??

any solutions?

its really annoying not to know how much battery left. i can remove battery indicator in status bar, no more needed..lol [emoji38]
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Predatorhaze:
You should have rebooted your phone after the first boot with new battery.

Battery stuck on 50% never happend to me,but all others did.

What about changing rom?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] olus:
i have rebootet several times. booting in twrp shows the same 50%. tonight i will backup and try another rom, then i will report here.

if anyone has solved this problem (by changing rom/vendor/kernel) please give me a hint.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] king1990:
You have two options, using nfound vendor/kernel or using any vendor plus Schwifty R4 (not R5) kernel.

It should report the battery correctly
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] olus:
i flashed schwifty r4, now battery reports correctly. thank you!!

but whats the bug here?

before i replaced my battery it worked as it should. replacing battery produces a bug in los16?

why newer kernels dont fix this?

strange..
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] king1990:
I can't say for sure , all of these 50% bug reports happened after replacing the battery.

currently I'm looking into this issue while building my kernel and hopefully we will find what causes this soon.

Hidden wifi issues.

Hello, I installed latest unofficial LOS16 on my Axon7u recently, A2017UV2.1.0B20v01_Bootstack_by_DrakenFX. Updated kermel to 3.18.136.

Everything seems to work nicely, although I would like to report a bug. I can't see/connect to the hidden WIFI network.

If I switch router to make SSID visible, then the smartphone connects to my WiFi. And alternatively, if I use "hide SSID" again, the smartphone would not see WiFi. Though, no problems with any other WiFi networks.

Also I have a question about vendor image. Currently I am using the one that comes with LOS16 image. I tried to flash NFound v1.1 and few other what would make my phone into constant reboots. Is there any vendor image, that is compatible with this ROM? Am I doing something wrong?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] runninghamster:
Firstly, change your bootstack as the B20 from Draken does not have system read/write, meaning Magisk will not work properly. Change it to Los15UniversalBootstackv2.

I'm not too sure about the hidden ssid bug, but you can use the search bar and see if anyone else has reported it.

As for the vendor image, Los 16 will only work with the vendor that comes with it, or another Los vendor. You cannot use Nfound vendor with Los 16.

This is really varying from a LOS 16 posting, and this is the ROM I'm using, but I've had the problem with other roms.

Now this might sound like an Apple excuse, but you might be holding it wrong. (-;

I find if I hold my phone so that the heel of my hand extends beyond the bottom of the phone, then people I'm talking to experience the same situation.

I phoned myself on another phone to figure it out.

Depending on the size of your paws and the desire to press the side buttons with your thumb this might be a hassle to change your grip.

It may sound far fetched, but it makes a huge difference for me.

Like many of these kind of things you can use this as a "feature" when dealing with annoying callers. (-:

Hi [MENTION=5027381]OrdenKrieger[/MENTION], first thanks for your great work, really appreciated!

You said yourself you're not using this device actively anymore so there will probably not be many further builds from you I suppose.

I'd like to build it on my own then, at least to have latest stuff from los itself (eg. security updates),

your source code link is only to the kernel, I checked your github and could not find any android_device_zte_axon7 like found for los15,

I saw there is one here from [MENTION=4911249]Unjustified Dev[/MENTION] https://github.com/C457/android_device_zte_axon7 but it does not have a lineage-16.0 branch

so I suspect it is not usable for los16.
