My phone had battery drain issue due to wakelocks, I can see Awake(screen off) and NETLINK and 7000000.ssusb prevent device from going to deep sleep. I also had few other issues like random restarts. They fixed random restarts by replacing the board, but battery drain issue still exist. I read somewhere that faulty USB port might cause kernel wakelocks.
So my question is does replacing board also replaces charging port in a device or my device still have an old charging USB port??
I see both of these wakelocks and their count is in thousands and in my case they do not prevent phone to get into deep sleep. Also no drain when I left the phone for a longer period of time (8 hours = 0-1% drain)
However, i had terrible battery drain because of bad wifi router, bought another router and soon after setting it up, battery life on my phone improved drastically. I wasted time on checking USB port, disabling MTP host, resetting the system, downgrading to Nougat, buying other brand USB cable, changing SIM card and so on, but problem was with wifi router.
So, I suggest you to carefully pinpoint what is causing battery drain before wasting more time and possibly money for something that is not causing issues.
Check if some app is draining the battery, check wifi router if you're using wifi network at home by turning off wifi on your Mi A1 when you go to sleep, next day put phone into airplane mode etc...There are many things you can check

I tried with factory resetting, so no apps apart from default ones. Wifi is turned off and no location enabled. So it shouldn't be issue of wifi router.

No. The charging port is at the bottom of the phone. The mainboard is at the top of the phone.

No charging port is different from motherboard and is very cheap. You can buy it from amazon and fix it yourself. Replacing the charging port solved my battery drain issue.

Hey guys,
I'm having a bad battery drain problem with my Touch HD. The phone will drain itself in less than 6hrs, even if it is sitting on a table with all radios turned off, freshly hard-reset, doing absolutely nothing.
Initially I thought it may be an issue with the ROM I was using, but flashing an original HTC ROM didn't help. I thought the radio may be the cause (even though it wasn't in use), but flashing different radios didn't help. I considered the SPL might be the problem, so I reflashed a stock one, didn't help.
I've even tried brand new batteries, but they all drain out like you wouldn't believe. It doesn't matter whether there is a SIM or microSD card in it or not, drain is the same.
What I have noticed is the bottom half of the back gets slightly warm, just sitting on a table doing nothing. This is not something I noticed before this problem began.
Can anyone suggest a solution? Or is it simply defective...
Switch to flight mode and see if drain persists. If it does, then some software must be preventing the device from going to sleep mode.
If you are confident there's no such software installed, might as well be a hardware issue...
If no drain when in flight mode, then you may have wi-fi/BT/wireless connections always on causing this.
I'm almost 100% certain, since it does it on several different ROMs (including stock ones), several different radios, all with the phone in flight mode, all straight after a hard reset. Even so, it shouldn't do it simply connected to the 3G network, an Xperia X1 connected to the same network sitting next to it doesn't experience anywhere near the drain of this thing.
Looks very much like a battery issue..
However have you tried charging it from wall socket rather than USB (USB seems to incompletely charge HD - though it may say 100% battery actually charges up to ~70% only).
spoilt battery?
I had this problem after using videocall only a week after getting the device (this was about 4 weeks ago)
The steps i took (which i got from here) was once the battery went down to 10% I turned off the phone and charged it to full from the power point (not via usb). Then I did the htc troubleshoot test (http://www.htc.com/www/faqs.aspx?p_id=179&cat=80&id=85780) and it seemed fine form then on. But in the tips section in here, its good to discharge and recharge your phone the first week or two you get it, I'm still doing it
Just to be clear, I know the basics about rooting and installing custom ROMs, but I do not know the fine details.
My 10.1 (purchased at launch) first started to experience a bad constant battery drain while in sleep mode when using stock ICS about 3 months ago. Shortly later, MTB wouldn't start up when connected to my PC, even after factory restoration. I rooted it and installed JB 4.1.1 with the 3.1 kernel, but the battery drain continued and I still could not get MTB to start up to transfer files via USB. I tried doing the various battery calibration and reset tricks (fully charge, shutdown for 1 hr, use tab until battery at 40-50%, shutdown for 5 hrs), but the drain continued while on standby. I decided to just deal with it and got into the habit of turning it off when not in use and using Kies Air to transfer files.
Now, the tab thinks it is constantly charging even when it is not plugged into the wall. While on, it will say "charging" on the lock screen and show the charging symbol on the battery. When turned off, it will show the battery icon constantly moving the green charge bar. For this reason, the battery continues to drain even when off.
Any solutions here? I tried factory restoring and using different ROMs (ICS and JB) but I think they used the same kernels? Do you think there is something physically wrong with the battery or the chip that controls the detection of charging and charge levels? Or perhaps the Tab thinks there is a constant USB connection? If it is something physical, any hope of repairs that will not cost close to the value of a new tab?
Any information would be appreciated
Thanks!
My Galaxy S5 was experiencing extreme battery drain, even while not in use and in my pocket.
After a bit of searching, it turns out I'm not alone. So I thought I'd share my potential fixes to this problem. Your solution may be different to others, so try each one until you find your battery works as good as it should, like mine now does.
Attached is what my battery drain looks like after these 3 tips, even during heavy use.
If you have any extra possible solution, then please post them.
Problem: Android 4.4.2 bug: When location is enabled it causes extreme battery drain. Because it doesn't let the phone sleep.
Solution: Turn off location services until a patch is released.
Problem: Quick Connect not allowing the phone to sleep.
Solution: Root your phone, and either delete or move the APK files: QuickConnect.apk & QuickConnectInteraction.apk from /system/app to somewhere else, such as a disabled folder.
Problem: Skype bug causing battery drain.
Solution: Uninstall Skype until a patch is released.
Hmmm that's strange, my S5 has the best battery life i've ever had on a phone.
I'm pretty sure you turn on the Always ready to connect in Quick Connect that causes thw device unable to sleep.

That wasn't working for me. No matter what I did, my battery was being demolished so that I had 50% 3 hours off-charge. Now I get so much more.

I was getting the battery drain and slow charging. Removed and reinstalled Google Search and that fixed the battery charging. I couldn't figure out the battery drain so I simply factory resetted it and it has been great since. I am at 30 hours since my last charge and still have 50% to go, with light use.

You say removing the Google Search fixed you problem with the slow charging of your device ?!? I have noticed that my device charges very slow connected to an USB3.0 port...it only charges with 450mA.

Backlight keys use very little power
I also use a lockscreen that changes backgrounds (Travel Wallpaper) and have gestures on at all times and my last charge lasted 48 hours and still had juice left . Although what you mentioned above might impact battery drain but only a little and wouldnt cause you to seek answers for poor battery life .Best solution is see whats keeping your phone awake (wakelock)

That can be right, most USB 3.0 ports on laptops and computers do not provide more than 500mA.
For fast charging always use the wall charger. When using the original charger that came with your phone and the original cable (USB 3.0 compatible) your device can pull the full 1800 mA from the charger, since it can sense that the charger is able to handle this safely. When you use a USB 2.0 compatible cable it will only pull 1200 mA from the charger, even if it's an original Samsung wall charger.
I had serious battery problems with my S5 too, battery drained within 8-16 hours. After I removed Skype problems seemed to be solved.
I've had the same problem battery drain only 15 hours I have turned few wifi settings off
Smart network - off
Keep wifi on during sleep - changed to only when plugged in (would have thought this would be default)
Always allow scanning - off
network notifications - off
Hope this helps someone last 2 hours only lost 1-2%

Ok. I am using now this kernel ktoonsez KT-SGS5 and with a normal USB2.0 cable I get 1000mA from my USB3.0 port and get 1800mA from my wall charger.

Cool, that means in this kernel some of the original power management restrictions have been removed. It would be interesting to see if the limit on charging via the contact points on the back of the phone (used for Qi wireless charging and by car mounts like Mountr that use inductive charging) now als can accept more than 750 mA...
Was having trouble with both issues, pulled battery with phone on, waited a minute, put battery back in, both problems fixed!
isnt this bad for the phone? Im having horrible battery life so I'll try anything but just wanna make sure

You wouldn't want do it if on a regular basis but you can try turning phone off, pulling battery out, putting it back in after a minute and if that doesn't work, try my method.
I would wait until the battery is super low and then reset network settings under the reset menu. Power down, pull battery and sim wait 30 sec to a minute and replace everything. Then plug in the phone first and then reboot. Let it charge completely and for about 20 minutes more after it reaches 100. If you do a lot of rebooting I have found the phone has issues. I only reboot with the phone plugged in, otherwise it drops 2% every reboot..
Be careful, I did that with a ZTE Zmax 2 once (75% charged battery) and it sent a phone into a bootloop. The only means of fixing it was that I luckily had a 2nd Zmax2 laying around and used its battery on the bootlooped phone which remedied the problem. Both batteries work fine , I just swapped them between the two phones.

I used to worry about this too. This is my first LG product and it MAY be different but at the Sprint store the first thing they would normally do is pull the nattery to look at the ESN. They never bothered to power it doen forst so I asked a couple times and was told it will mot hurt anything. I had Samsung products for uears and have done battery pulls at all levels of charge and for many reasons, but I never had a problem as long as the battery had enough juice left to boot the phone. If not I had to charge it, LoL.
Just thought I would share, I personally wouldn't worry.
I know on my old Nexus 6 pulling the battery with phone on was only an issue with fsync disabled using a custom kernel. I think most phones have built in protection to stop this from damaging the file system.
so a battery pull is your fix? lol some ppl should be hard resetting every so often regardlessi reboot at least once a day
hi
my v20 phone battery draining was about 1% per hour before (about 7% totally ) and recently increased to 2% during sleeping time overnight. (draining 15% overnight in sleeping state)
it seems that during day either performance off battery is decreased.(about 5h with wifi and screen on usage)
Fast charging while second screen is On , is slower than when it is off therefore when second screen is Off , fast charging goes better . exactly , first 30 mins fast charging makes about 40% battery charge(instead of 50%) and after 60 min leads to 85% and full charging taking place after about 100 min instead of 80 mins.
another important thing is that sometimes shades have been seen on the LCD that many users have complained about it.
phone information is :
Android security patch level: September 1, 2017
BASEBAND : MPSS.TH.2.0.1.c3-00045-M8996FAAAANAZM-1
KERNEL : 3.18.31
BUILD NUMBER : NRD90M
SOFTWARE VERSION : V10g-AME-XX
MODEL NUMBER : LG-H990ds
my actions are as follows :
phone is factory reseted. No third party apps is installed. [especially social media apps.]
battery calibration steps for not rooted phones is taken place.(turning off the phone and charging several times repeatedly).
testing battery drain in safe mode in done and didn't change results
turn off location services and location scanning for WiFi and Bluetooth scanning
turn off WiFi being On during screen is Off.
turn off auto sync, NFC, GPS etc.
not using auto brightness.
not using comfort view .
turn off location services and location scanning for WiFi and Bluetooth scanning
second screen is off during test overnight. (either with second screen is ON with faced down to lower brightness in other day test )
phone is in Air Plane Mode and all data services is off.
system apps like Google services and Play and Assistance is limited by permissions.
following are some advanced battery drain overnight figures of my phone for more analyzing.
any help with this issue is appreciated.
While I don't get extremely bad battery drain. The few times I've noticed it going down a bit faster than normal have had Android system at the top of the list or at least 2nd in place. A reboot usually fixes it for a while. This has happened in every ROM I've tried. Also I swear that stupid Wi-Fi scanning when WiFi is off option in locations settings turns itself on when it feels like it. I rarely turn my location on and I've checked a few times and that feature is on for whatever reason
Power down.
Pull battery.
Hold power button for one minute to discharge any juice that may be on the motherboard.
Let phone sit for 30 minutes.
Put battery back in.
Power up.
The motherboard and battery should now be re-calibrated. If you still have problems, try a new battery.
I was having heavy power drain due to the 70000.ssusb kernel wakelock. I tried almost everything from flashing my ROM to replacing the battery to replacing the motherboard and nothing helped.
I've found a workaround to it though (a fellow user had posted it on some thread).
If you're facing power drain due to this wakelock, buy an otg adapter and connect it to your phone, without a pendrive. This fixed the issue.
I used have less than 3 hours of SoT but now it's 6 hours.
You can also root your phone and change some otg settings to fix it, but this is a safe workaround without root.
A lot of people are facing this issue, so thought I'd post this.

Did you get your USB ports changed in the service center?
Nah they wouldn't get it changed saying they're perfectly fine.
I used to have it on 8.0, but during some updates and patches it disappeared.
I think the problem is in the port, I have reasons to believe mine has water damage.
Don't have a otg adapter but disabling USB host via software does the trick to stop this wakelock.

Can you let me know how to do this? Does this require root
I have this wakelock too! BUT!
I flashed yesterday Mint kernel, left the phone for 8 hours from 100% charge, came back and battery was at 99%. Phone was in deep sleep 99% of the time. Still have this wakelock but I guess mint kernel does something to prevent battery drain. On stock kernel it was draining battery about 20% in a period of 8 hours

Yes always root is required to modify system files.
Open terminal emulator execute su, then paste the command and execute

After few days of researching and testing, this 7000000.ssusb wakelock has nothing to do with battery drain, at least in my case. And it does NOT prevent my phone to go into sleep. One time wakelock count was about 4000, and phone was Awake (Screen Off) only 1-2 minutes. Battery did not drain at all during the 8 hour test.
Airplane mode ON = No drain
Airplane mode OFF - Removed SIM cards - wifi ON = Drained ~15% overnight
Airplane mode ON - wifi enabled = Drain ~15% overnight
Airplane mode OFF - wifi disabled = Drain 1% overnight.
All this time 7000000.ssusb ''wakelock'' was present.
I suspect that wireless router is causing drain overnight or something related to wireless network.
I got this wakelock too. But in my case this wakelock occured after I flashed stock rom (july update) via MiFlashTool because my rom wont boot properly after installing custom rom (like wont boot after restarting, bootlooping). I've tried with flashed 8.1 stock rom and with any custom rom + kernel that I know have a good deep sleep (LR + Project K v16, this gave me 1% overnight drain with wifi and mobile data on earlier) but still it drains me like 20% over night. I'm googling here and there, someone posted that he can get rid of this problem by following restore imei guide but he said that we shouldn't following that guide if we are not messing with our imei or we are not losing our imei, so I'm afraid to do that. I'm still wondering why reflashing stock rom make a new wakelock problem that we really didn't want.
Hello guys, the only solution i found it´s using the metaphoenix kernel. Its the only kernel where my phone can go to deep sleep and not having wakelocks we are all suffering. i dont know what does the kernel do but with other kernel in idle/hour i had 3-4% and with metaphoenix i get 0.6-0.8% idle/hour. i hope this helps you out.
Greetings
I finally solved my drain issue and it was not 7000000.ssusb related, even if this ''wakelock'' is still present my phone goes into deep sleep well with only 0%-1% drain overnight (8 hour period). Also my SOT increased drastically, from 5 hours to almost 10 hours (Custom ROM and kernel, from 100% to 1%) Now i charge my phone every second day! :highfive:
I bought Xiaomi Mi Wifi 3C router. Drain from 15%-20% dropped to 0%-1%. Tried 2 routers before Xiaomi router and both caused battery drain during idle (routers were cheap and old - Netis and TP-Link).
So before assuming this wakelock is the cause for drain, please consider checking other things.
Turn OFF wifi during the night, if battery drain reduces drastically then consider replacing router (assuming you checked for other symptoms that can cause drain)
I also have NETLINK wakelock, but drain is still 0%-1% in the 8 hour period.
