Overheating and fast battery drain - Huawei Mate 9 Questions & Answers

Hello guys,
Uncharacteristically, for getting to a month now my phone overheats at least 3 times a day and the battery is gone by 4pm.
This is the same phone that gave me juice till the next day. Also it wasn't a gradual thing but sudden. And I haven't done any update for over two months.
I feel I may have a rogue app.
Please, what is the best way to isolate and identify the app so I can uninstall it? Or if it's something else I trace.
I'm on stock MHA-L29 8.0.0.368(C636), never unlocked or rooted.
Thanks

Dear user,
Please install battery stats app from play store and analyse the root cause.

[Q] How do I fix my terrible S6 battery life?

Hi guys. I just created an account to these forums. I've used them before when rooting a previous phone. I have a problem with my new S6. I got it about three weeks ago, and I love it. The only problem I have is the incredibly short battery life. There has to be a problem with my phone, because I'll have a battery life of about 5 hours on a good day, but usually 2 or 3. The phone will get mildly hot, and all battery will drain rapidly. I will regularly lose ~40-50% in an hour after it starts heating up. I've been simply dealing with it for a while, after a failed attempt to find a solution on Google. I regularly close my apps, and I even have powersaver on at all times now. Last night, I closed all apps, then restarted my phone. It was at 98 when I fell asleep. I woke up 9 hours later and it was dead. I have checked the battery info a couple times, but I don't ever see anything rapidly draining battery. Could this be a hardware problem?
I have a Verizon S6 regular. Model number SM-G920V
Try to calibrate your battery first.
I suggest reinstalling the software using Samsung's smart manager and updating to 5.1.1, I never had your issues but noticed a big improvement with battery life. I'm sure you have a rogue app somewhere running havoc. There's also a lot of things you can do to improve battery life after reset, like disabling background data on certain apps that you need need constantly connecting and using data like Facebook when it's not even in use. Just play around with your phone to know the ins and outs

Thanks for the suggestion. Where is the Smart Manager? I Googled it, and found a thread saying
It is included on the phone, however there is no way to access it that I've found. You can find it under Application Manager - ALL. Scroll down to Smart Manager and select it, you will find that the app is running but we are cannot access it and the DISABLE button is grayed out. My guess is that Verizon wants us to use their My Verizon Mobile app instead of Smart Manager. I heard that AT&T did the same thing.

My bad it's actually called smart switch. I just got brainwashed seeing it that widget all the time on my homescreen.

I suggest wiping the cache. I was experiencing a similar issue. After wiping the cache, consumption return to normal.

98% gone during 9 hours of sleeping? wow...
1) Do the factory reset, full wipe and see if its gonna get any better.
2) If still the same problem, then download latest firmware for your model from sammobile.com http://www.sammobile.com/firmwares/database/SM-G920V/ and flash it via Odin / Download mode
If still the same issue, then contact samsung for the warranty :X

You might try a Sprint fix since your Verizon S6 has CDMA too. Since you've got a Verizon phone, this setting may be somewhat different. On my Sprint S6, I changed the setting under 'Mobile Network', then 'Network Mode' to LTE/CDMA' instead of 'Automatic'. That made my battery life much better. I think I remember a friend with a Verizon S6 and it had 'Global' instead of 'Automatic'. So change it out of 'Global' mode and see what happens.

Battery life greatly getting worse

Has anyone noticed their battery getting incredibly worse over time? I bought my S7 on release (non edge). And since then, I've noticed that it doesn't last no where near as long. Today, for example I started my day at 7:00am when the battery was 100%. As of 30 minutes ago, the battery reached critically low (5%). From 7am all I did was watch a few videos, facebook, snapchat and then play music. But all the above for not too long.
I've also noticed that once the phone hits the 15% battery (I know due to the notification), that within minutes the battery can be done to 10% or so, without touching it.
I'm more so tempted just to take it back, unless there's an easy fix OR it's a known issue with the current version.
Thanks!

I've definitely noticed this since rooting. Maybe it has something to do with that? Like a ROM you flashed or what not? I'd like some suggestions here as well.
Thanks!

I haven't rooted the S7, it was the first phone that I've left stock from opening.
What does the battery stats say is using the most mAh?
Facebook app is a known battery hog
Obviously over time, you'll install different things, and slowly the phone will start using more and more power running background apps
A backup and Factory reset will show if there is a hardware / battery issue, or if it's purely from stuff you've installed over time
Also clearing the caches from recovery could help
yeah ive noticed this too. My usage habits havent changed but my battery life is almost half of what it was when i just got the phone.

Cache has been cleared from recovery, and I don't generally install many apps so since I've bought the phone the apps have stayed the same.
Android system is always on top. Unless of course I spend hours on Facebook.
Might have to factory reset. I've used my phone with the same apps and time since I've bought it, and I'm finding I'm charging it 3x as much.
I think it's a root issue - deep sleep.
After S6 Edge Plus, when you root a samsung phone, it won't go in deep sleep. I believe there's a fix for that.
Have you checked the battery usage stats? It gives you the breakdown on what apps are eating up the battery.
I have had my S7 for about a month and battery is about the same.
Just to update this thread for those that may have a similar issue...the other day I couldn't live with the battery life the way it was. The phone used 50% in several hours where I barely used it.
Decided to completely re-flash with stock (was stock before) as opposed to simply wiping all data. A week in, and the phone's battery life is back to the way it was. I went to bed when it was on 100% (as a test) and woke up 7 hours later with the phone on 94%, with wifi, location and bluetooth on.
Not sure what had caused it to use so much battery previously, but it's back to what it should be and that's all that matters.
hi with my s7 exynos i do 3h screen. i think there is a problem. i bought my s7 one week ago. can anyone help me?
Rooting and installing custom kernels when done right should greatly increase the battery life of your device. This is a well known guide here on XDA for improving battery life for our devices.
That being said, Lithium Ion Batteries hold less charge the more cycles they are put through, its a given fact but as you said your device is relatively new and therefore should not be experiencing this kind of problem. The way I see this is there are 3 possibilities which may be causing the said problem...
1) You have rooted the device and done some modification/s. ( which you haven't done )
2) Your battery is being drained by a service ( Like Oculus or VR ) in fact a number of reddit users complained their S7 was overheating and battery was draining really fast for some reason. Check This page out, It might help you.
3) Battery Defect, you must've gotten a "bad" model, if you haven't tripped KNOX you could try bringing your phone to Samsung and see if they would fix or replace it.
Good luck
I think this has to due to them samsung updates. As far as i know samsung been always doing things like this where they made the OS slow as hell after a while so you gonna get a upgrade sooner but a battery should last 2 years minimal without degrading.

i get like 5 hours screen on time and bout 1 day standby time but i have most bloatware disabled with the package disabler. But if i was you i would contact samsung.
This happens with Samsung updates on every Galaxy phone. It's like a curse. It's unavoidable.

May i ask if the people with these problems use the fast charge? I hearing many bad things bout this so i switched it off and must say the normal charge isn't that slow and if it can keep the battery good for longer then we all should use this.
I turned fast charge off about a week after I got the phone, was making the phone and charger pretty hot for the sake of about 5-10 mins quicker charge
Pointless really, unless you are desperate, only have a few mins spare and need as much power as possible in that short time, and if that's the case, enable it for that one time
Restrict background data on all but the most important apps (phone, text, email), dave power all but the most important apps. Battery life is fine

XZ 41.3.A.2.128 excessive battery drain

Anyone experiencing excessive battery drain with the May patch update? Android system drains the battery too much. I just reset my phone 2 days ago, installed my usual apps, updated the system and then this happens now. Any fix on this?
Hello,
It's actually a well known problem in the community
1. I have submitted a report to Sony and request them to release a software update to fix the Kernel
- which means that our best chance here is to hope it is fixed with an update, the root cause is the Kernel not being optimized
2. I am on the verge of snapping this phone in half as I asked around the community and received no answers , been trying to fix this for 1 year straight

Out of the blue: A factory reset could help.
You definitely have a problem that your phone does not idle (look at my screenshots (v ..128):
idle (Ruhezustand) should always be in the top three).
One of your messengers might the culprit.
Try to disable them all and switch them on one after another to find a possible culprit.
Hi,
I too have these issues. Did you manage to workout which app was at fault?
Yes, another case here. We are still investigating the problem and checking if it's some app or system itself. Most of battery was used by android system and battery was empty in 11 hours.
Problems started with 41.3.A.2.128.
So is it worth updating?

In our case problem was either facebook or whatsapp. Both remove/disabled and now battery lasts as always.
Yes, it is horrible!! I woke up at 7 am, took my phone off the charger and never made a call, or even turned on wifi. I came back from being outside around 11:30 and I was down to %34!! Without the phone having done nothing but sit there and recieve 2 missed calls and 5 text messages!! I usually get 2-3 days on a charge with my XZS depending what I am doing. Needs to be fixed and fast!!!!
Dont factory reset, because the battery issue will not go away for rom issues.
But the "Messages" app do look suspicious for 5%.
There are some devs like to tell people factory reset for everything first and even reset for regular stock rom updates.
Its a bit excessive, like formatting Windows for every time it crashes or even for every Windows updates... Unless you enjoy restoring data & apps.
Should try something to troubleshoot and fix it first before resetting, so we know whats wrong.
The battery drain on idle is slightly better after a week, but we still have to wait and see.
i have problems too, with last existenz with this version battery its a joke

Experiencing battery drain on new phone

I bought my OP7 7 days ago , I have been experiencing poor battery life from day 1. SOT is around 3 to 4 hours , standby time is around 22 hours. If I leave the phone idle for an hour , the battery percentage drops 4 percent without any activity . I do remember receiving an OTA update on the first boot , I don't know if that was the culprit or I have been sold a lemon. I have waited for a week hoping that the battery life would improve after a few charge cycles but there has been no change.
Is everybody else facing the same issue , especially those who are on 9.5.x ?
I have to say that i do not experience any issues like that. The overnight drain is minimal, a few % over 8 - 9 hours, and overall the screen time is as expected (i daily play some extremely CPU heavy games for a couple of hours and i still get around 5 hours of screen).
I'm also experiencing the same issues. When phone idle abnormal battery drain.
Can you tell me if the phone with the cellular data turned off, uses data from your plan? Can you see that?
I had same issue with my phone so then I returned it to Amazon and I received replacement which is working fine and giving good battery backup.

I made 2 returns, I'm now with the third phone and still had the same issue. I'm losing my mind how is that possible. And for sure is all new phones with different imei.
Every user has different usage profiles.
If your phone is rooted install Better Battery stats or FK to get detailed info about the rogue process that may be consuming more battery than it should.

Help : Fast battery drainage

Did anyone encounter the same problem??
Two 5ii of mine are draining too fast this month.
I don't think it's a hardware problem, but a software problem.
Anyone??

I noticed that too for a week.
It must have been some Google service update that generated a lot of unusual wakelocks.
In my case, it's gone and back to normal.
reboot your device just in case
Same here as I texted this. I've getting SOT like less than 4 hours per day even I've restricted battery on some apps and restricting background data. However the issue still persists.
Kinda agree with the Google Service Update thingy since after some play store or updates installed and the battery drainage is just absurd.
Also throttling the CPU a lot and temperature is higher than usual, almost achieving 40°C in just usual social media, browsing and working.
Worst is that I've reboot in safe mode, and multiple restarts and is still draining battery vigorously.
Hope some software or google updates can solve this issue quickly.
From my experience (see my previous post) i had the problem for about 1 week and then it went away.
And lately, I'm getting the best-ever deep sleep battery consumption during night: ~3% .
I did not tweak any app battery policy in settings and I'm using stock A12 latest update.
You may have some rogue app update that is not in tune with the correct power management posture.
I have the same issue. It seems to have been triggered by poor network connectivity or something. The first time I had this issue, I had to solve it via software repair. I'm not keen to go through the process for the second time. I have shut down and restarted my phone several times.
There have been a number of posts on Reddit recently about massive battery drain with Sony phones.
Here and here and here and here
Seems like it's a Sony Vs Google problem
I have had the same huge battery drain, with my phone going from lasting two days between charges, to now getting hot and lasting just 15 hours
When I look at running apps, I see Gooogle Play Services has 2 or 3 instancnces. Some with 13 services. In the last two weeks Play Services has used 825Mb of data. Feels like my phone has become an AV transmitter.
Hello guys, today I noticed that the battery is finally back to normal. I turned on auto-update for everything and let it update whatever it needs to at the very first place.
Hope this kind of **** don't happen ever again.
I don't have auto-update and that issue only lasted a few days
