[Q] Power Management Issues--Phone heating up ridiculously fast

Ok, so I think there is something wrong with my phone. I flashed a kernel over a rom a few days ago, and out of nowhere, the phone started heating up ridiculously fast.
I wiped everything, and installed the ROM normally, and the heating issue remained.
So today, I installed CM on my phone, thinking that the original ROM was the cause of all of it.
As it turns out, it's not.
When the phone is asleep, the battery is at 98.6 F. When I send a text message, it jumps to 100.4 F.
In spare parts, it says that the battery condition is GOOD, so idk what the problem could be here. Should I wipe battery stats or something?
And before any of you say anything about multitasking-- Wifi is on, GPS Off, Data On. I am running text messaging, and a few other things [dialer, etc]. Nothing extravagant. I have run youtube, music, and 3 other battery intensive apps before and nothing has ever heated up before. Idk wtf is going on right now.

4.1.83 - random reboots a thing of the past?

I realized today that I hadn't had a random reboot in a while. From day 1 I could count on 1-2 random rebooted with my Atrix.
Sure enough, my uptime is 280hrs+, which is in line with when I took the OTA update. My wife's phone appears to be the same, and it was rebooting at a similar rate to mine before the update.
Both are rooted/non market enabled but not modded.
How's your stability been on 4.1.83?
Sent from my MB860 using XDA App

I had one strange reboot this morning, my phone had been lagging up a lot, along with the screen not turning on when I pressed the sleep button.
I look down a minute later and I see the Motorola logo. But afterwards it seemed just dandy.

Random reboots
I just bought this phone Friday at 7:45pm. It was working fine when I got home Friday night after purchasing it. I hooked it up to my pc and got the needed updates to 4.1.57.MB860.ATT.en.US. Saturday morning I installed one game bejeweled and advance task manager before heading out to work.
I got back home around 1:30pm and started setting up my contacts on the phone. Around 6:00pm I left the phone plugged into my pc and heard the phone rebooting from the other room. At first I thought maybe there was an update and that's why it was rebooting.
Two hours later it did the same thing again with no warning about a reboot when I was manually adding new contacts. I notice there was another update available to version 4.1.83 which I now have installed on the phone and it's still rebooting on its own.
I also noticed that my battery was right at 60% and while plugged up to my pc it was only recharging 10% every hour on the hour not sure if that's normal for this phone.
(Two hours later battery power at 90% with a solid green power light visible but taking forever to reach 100%)
Also right after the 4.1.83 update the phone would reboot and then the battery light on the phone would just randomly flash red with the motorola logo sitting on the screen. I had to pop the battery out, waited for about 30's before putting the battery back in and powering it back up and it still sat on the logo screen with the red flashing light.
(The battery is now at 100% but 3mins after unplugging it from the pc it displays 90% again all I've did is watch it reboot on its own.)
I removed the battery again but waited for about 5mins before powering it up and this time it actually booted up like normal and about 30mins later another reboot.
I also noticed that as soon as I finish watching a video with youtube the phone reboots a few seconds after the screen goes to sleep. Now as I am writing this comment I decided to uninstall that advance task manager program and do a reboot. The phone is at 80% and after I watch about three videos with youtube the phone didn't reboot.
I have no idea what's up with this phone and I really like it alot except for this mysterious rebooting not to mention other people experiencing random reboots. I read online where a lot of people where saying it was due to a bad battery and that they got a new battery from Att and the problem went away.
I am really thinking about turning this one in for a new replacement but some people are saying even after doing that they still kept having the problems.
Could this really be something wrong with the updates that is causing issues with the phone or is it just a bunch of bad batteries?

Battery?
Back again, in the post I made earlier I mentioned how the phone wouldn't randomly reboot when the battery was around 80% well the battery charged to 90% and the random rebooting has started up again and it has rebooted 3 times back to back now that it is at 90%.......I think I am going back to the Att store when they open today and try getting a new battery............

If I were you I would get a replacement phone. I did have one random reboot since updating to 4.1.83 and that was the first ever I've noticed with my phone. Otherwise I haven't noticed any issues. As for charging via a pc I did hear that was slow. I charge via power outlet or using a car adapter and both are fairly quick. Good luck.

Battery?
I decided to do a factory reset on the phone first and the funny thing is after the reset, the phone still showed that it had the latest update installed even though I still had to go through the setup process just like when I first purchased the phone. So far it appears to be working and hasn't rebooted on me yet. No rebooting after playing Youtube videos either. The only small pet peeve I have at the moment is the Facebook & MySpace contact photos will not show up for some unknown reason in the contacts sections, they're just empty picture frames. The contact photos that do show up are the ones from my google gmail account and I manually added those online myself so those automatically transfer when my phone syncs with the gmail account.
And the MySpace widget doesn't show a photo as well but the info in the widget is current. That's way better than experiencing random rebooting when you really need your phone the most.

This is normal. A FR cleans all of the user data reseting it back to a "clean" version of the flashed rom.
I can say that I have also not had any reboots since .83 but it is also the first time i have loaded gingerblur.

Note 4 battery, signal and performance problem.

I've been having this strange problem these last few weeks. It happens in different ways.
1. Bellow 25% phone randomly shuts off then when i reboot its 0% battery.
2. Bellow 25% at random % I lose phone signal then the phone starts to lag and capacitive keys don't work then the phone shuts off and when i power it on its at 0%.
3. Phone gets to 15% i plug it in to charge, it doesn't charge but discharges to 0% then shuts off and after that it charges.
If i remove the battery then put it back in after it says 0% it may show 30%/20/15/13/25/30 etc. Sometime it doesn't charge after 87% or 92%. Is it the battery or is something else at fault? Also i can't get more then 2h15m screen time whatever i do and wifi drain is 30% in gsam.

Earlier I had same problemes on my Note 1 and it was because of my battery. Probably your problemes are becuse of your battery too.

Ok I will try a new battery.

I have exactly the same problem!!!!
Like exactly.
However I'd like to add some things:
1. Sometimes the radio signal for mobile starts randomly cutting in and out. It will be full bars, LTE, then nothing, no signal symbol. Then Full bars again, then no signal. In 1 minute revolutions. I am not physically moving during this time.
2. Even at near full battery the phone will get super laggy, stutter, and then finally crash. Once it reboots the battery will be 40% or something. Not super low but lower.
3. The camera seems to have a huge effect as well. I will open the camera, take a picture, and the picture won't save...it will just start to freeze the phone up until I have to pull the battery or it reboots on its own.
I also have a new battery coming in the mail.
However I should note that I am Note 4 910-H using a 910-C variant Custom ROM.
I was worried it was the special Modem I flashed to make the C variant ROM work on my H variant phone that was causing the problem.
Great, but unfortunate to see someone else having this issue too.
Ill post results of the new battery here.
Btw, ive been able to resurrect it from a very low state of charge (3% etc). The only way to do this is to use my fast charger. The fast charger is the only thing that will save it. Even then it takes ages to charge and gets white hot while it does. Its like the fast charger is battling for charge against some unknown force.

Post if you remember when you get your new battery. Hope that fixes it for you.

hi
my note 4 910c become very hot when i use the internet , can i change the modem from lower android like 4.2 to android 6 ? is it work ?

I have exactly the same problem and please if any1 finds any solution just share it here... I tried almost everything but not a new battery.
Battery Calibration By All The Ways, Battery Quick Start via *#0228#, Many Custom ROMs, Many Custom Kernels and Many Stock ROMs and the problem still the same even after I cleanly installed stock 6.0.1 ... Any help please.
Thanks in advance.

New Battery fixed 99% of my problems.
However the phone still randomly freezes and disconnects from cell service.
I think its the modem driver. Freezing might also be due to sd card.

Battery drains fast and is always warm even after a battery change

[TL;DR]
Phone battery suddenly drains faster than usual, drains to 0% overnight. Problem still persist even after April update and after battery change. Can't find any solutions. Help me.
Hey, so about a week ago something very strange happened to my Mi A1 and got worse overtime. So what happened was my battery went from 80+% to 0% overnight. I woke up confused and just recharged it and didn't think too much. After a full charge, I noticed the battery drains abit more than usual and had to plug it in constantly. Before going to bed I charged my phone to 100% to see if it would drain to 0% again. It did. As time passes the problem gets worst. The phone started getting warm when charging (around 40+°C up to 50°C) then after a while the phone runs warm even when not charging (never goes below 40°C). My phone always used to run at about 30-35°C even when charging. I changed the battery myself because there was no warranty on it but it didn't fix the problem. However it did help abit. The battery drains ever so slightly slower now but still drains to 0% overnight. It still runs warm but now it does go below 40°C (rarely). Before and after the battery change, the discharging rate is about 700mA and sometimes reaches 1000+mA (used an app called Ampere, not too sure how accurate it is). The phone was also warmer than usual when charging even when the phone was off (before and after the battery change). I tried factory resetting to see if that does anything but had no luck. I also tried using a Wakelock detector app to see if there was an app excessively triggering a wakelock but all seemed normal. I even tried downloading a "battery calibration app" which obviously didn't work. So I feel like it's a hardware problem.
Now here's what I did and did not do to the phone before the problem happened. What I did was I do charge the phone quite alot most of the time. What I mean by that is when it hits about 30% I'll plug it in but I never leave it plugged in after a full charge or charge it overnight and I seldom let the battery drain to below 10%. Even so, the phone never got warm like how it is now. That's about all I did to it. Now what I didn't do was, I never tried to install custom ROMs or root/modify my phone in anyway except for the post about how to enable 4G+ which didn't work for me.. My phone is completely stock. I also didn't install any new apps from the playstore or from any 3rd party sites nor were there any updates for any apps installed in my phone. I've had the same apps installed for a couple of months before this happened. I also haven't dropped my phone for a couple of months. I only dropped it less than 5 times from short heights and I have a very rugged case on. I also didn't use any 3rd party chargers. I'm still using the charging brick and cable that came with the phone. I have tried using other chargers that are 2A but no luck. So basically I didn't do anything out of the ordinary prior to this problem.
Just some extra information
1. The hottest part of the phone is at the top right corner of the back. I assume the CPU is there (?).
2. It happened before the April update. It was the same before and after the April update.
3. Phone is running on Android Pie if that wasn't clear
4. The phone is only 10 months old
5. My phone is the Global ROM version
6. Performance wise, its still responsive and snappy. Doesn't lag or freeze or anything.
6. I always have mobile data on and use it as hotspot for my laptop at uni. I have been using it like that for the past 9 months. However the problem happened when I was at home during sem break so I was mostly connected to Wi-Fi.
Sorry for such a long post. I hope somewhere out there, there is someone who can help me or other people that have a similar problem so we can fix it.
Thanks.

In the upper right corner, should be the modem area.
Try holding the phone on airplane mode during the night and monitor drain.
Also, try changing the SIM slot and do an APN reset. If this fails too, try changing your SIM card or if u can, try another operator SIM.
If you changed any value with QXDM PRO , try and put back the default values.
Good luck

VNS-L23 Battery Issues

Hello all.
Using a VNS-L23 running VNS-L23c605b362. I notice these days that my battery drains unbelievably fast. In 10 minutes the drain is almost 30-40%. This is with only Whatsapp running in the background as the phone doesn't have Insta, FB or any other social apps installed.
There's also an issue where the phone battery will dramatically drop to 0 from any percentage. Telltale signs that it's about to happen is usually that the phone screen stops responding, starts pressing by itself all over randomly then it shuts down because it senses that it's at 0%. (I've had this happen from 90% already)
Any help in figuring this out will be greatly appreciated.
As an aside, I've tried to update the firmware using Firmware Finder, but none of the update packages seem to want to work.

Hi man !
maybe your battery need to be replaced ...
Well, i will suggest first, to backups your stuff.
Boot into recovery mode, wipe cache and reboot system....
Install an app like BetterBatteryStats (BBS) to check if something is wrong.
And for your firmware, if FF doesn't work, you can unlock the bootloader, install a TWRP
and use Huawei Recovery Updater (HuRU) to flash whatever compatible nougat version you like.
Good luck.
Cheers
