[Q] Battery life

Hello everyone I hope I got the right forum
I have a problem with the new system update released
The new update did not help at all to my nexus
I ran out of battery really fast, before the update it was fine
Battery had stayed a long time
What should I do?

A quick look through that thread shows that it is focused on problems relating to Google Services. Since the update, I too am having issues with the battery draining more quickly than it ever did before. However, it appears to be msm_hsic_host wakelock causing the problem. Google services are a very small part of my battery usage.
I have posted a couple times about it in various threads, but I haven't seen a fix that applies to 4.3.
The battery drain is out of hand. I love my N4, but this is a big turn off for me.
I have tried these configurations to make sure it wasn't an oddball app causing the problem -
Stock 4.3 with stock Kernel - no root/stock recovery - Only apps being the ones that load on a factory reset
Wiped all partitions and reloaded stock 4.3/gapps/no root/stock recovery
Stock 4.3/rooted/TWRP/Stock gapps
Stock 4.3/rooted/TWRP/gapps+ a handful of other apps (photobucket/es file explorer/bbs - essentially, my normal config)
Added note - I also have cell broadcasts of all types turned off.
All of the above combinations respond the same way in regard to battery drain overnight. 7-9 hours off the charger/no screen time nets me 25-30% loss of battery from a full charge. msm_hsic shows up in BBS with 1.75 to 2.5 hours of wake time and is the highest power consumer. Putting the phone in flight mode reduces power consumption to ~2% over the same 7-9 hour timeframe. Just turning wifi off doesn't change anything.
Ideas anyone?

As far as I know, this wakelock is caused because of the usage of 3G, like browsing, syncing, or any other thing that consumes data. This drain for me is usually between 10%-15%. There is no way t completely get rid of it, because it is part of the Android system.
There are many kernels that tried to fix this, about stock image and JW branch I don´t know, but maybe you should try to install an AOSP variant, because AOSP has many bugs fixed.
Also I remember I read somewhere that also bad radio could be causing this kind of issues, so try to get latest radio/bootloader for 4.3.
Hope it helps.

To avoid having loose ends out there (in case anyone finds this thread during a search) - The problem turned out to be the latest radio. Not my lack of it :lol:
After flashing back to the .48 radio, from the .84 radio - everything is back to normal. No more weird Android OS wakelocks. ~3-4% battery drain overnight instead of 20-30%
There are more and more people popping up on XDA with this problem. So far, all of them that I have seen are outside the US. A few have even discovered the same fix.
So - future person that finds this thread during a search, look into the possibility of flashing back to version .48 of the radio. Hopefully this saves someone the trouble of experimenting with a bunch of different ROMs and kernels.

[Q] Strange Wakelocks causing excessive battery drain

I just bought a droid razr m xt907 refurbished off ebay. I'm currently running it on the Telus network up in Canada. Everything works fine, I can receive calls and text messages just fine. My only problem is that whenever I'm connected to Telus or disconnected from all networks, I get three wakelocks that hold the phone awake sucking the battery. If I'm in airplane mode the three wakelocks disappear, the phone can sleep and I get excellent battery life. The wakelocks are called smdcntl0, smdcntl1, and radio-interface. In case it is relevant, I'm on 3G all the time since Telus doesn't run a 2G network. I've tried switching basebands and that didn't change anything, the wakelocks also follow me no matter which rom I use, I get the same wakelocks on stock 4.1.2, on aokp 4.2.2, and on carbon rom. Also, if anyone has a copy of the australian non-hlos.bin, I would like to try that to see if it helps.
If anybody has any suggestions I would greatly appreciate it, thank you.

judging from your 3rd screenshot, looks like your phone is having trouble holding onto a signal.
try a custom kernel.

Flashing aokp (which has a different kernel) really helped with the reception, I've gone from 2/3 bars to a consistent 4, thanks. The phone still won't deep sleep though.

I have same problem on stock since first day i have Razr M.
Many wakelocks when screen is off, but this doesn't drains battery.

get cpuspy and check after a full day. there is also an app called CPU Sleeper which will help.
however, if your battery is not draining, then I would not tweak anything.

then there really is no problem, right?

My battery still drains, the wakelocks are still there, I just get better reception. My cpu spends all of its time at 384mhz.

here's what I suggest. get the CPUSpy app (free on the market). charge the phone to 100%, refresh the timers in the CPUSpy app (or reboot the phone). then, over the course of the day, check back in the app to see if the phone has hit the deep sleep mode.
if not, then try the Greenify app to hibernate some apps that you suspect could be causing the issue.

They're kernel wakelocks, those aren't caused by apps. They also disappear when I go onto airplane mode so I think it has something to do with the modem. I actually have a log from betterbatterystats showing cpu states, it only deep sleeps for a few minutes if the phone's on all day.

then something's up with your kernel or modem. are you sure you are getting a strong signal? could also very well be the tower in your area (cell or mobile data)
I had some serious battery drainage when I tried to install an updated radio on an older kernel awhile back....

You need a full restore to stock. Then boot get everything working then do what you want.
See my goodies signature link all is there.

Thanks for your input, but the wakelocks are still there, and it still dies in a few hours of not using it.

So you did some kind of restore? What did you do exactly?

I ask cause your sw is a mess. Radio is new. Sys is old.
You should have, with that radio:
System Version 98.16.3.XT907.Verizon.en.US.
Build Number 9.8.1Q-78-1.

[sorry wrong topic]

you can try wiping every thing and just booting any rom or stock.
maybe its some apps that it has in the background that your not seeing

[Q] [SOLVED, kinda] Weird battery drain for no apparent reason

Hello all,
I own an international N9005.
Up until recently, I used the stock Samsung ROM with good battery life.
A couple of weeks ago, with no apparent reason, I started getting horrid battery life - in access of 10% drop -per hour- in idle (as opposed to 1-3%).
I removed more-or-less everything, disabled more-or-less everything but nothing seems to work.
Got root (there goes the warranty) tried looking for Wake-locks and nothing. The Note3 is 97% (!!!) awake even with everything disabled, and in the wake looks screen both user and kernel I only see 1-2 minutes (!).
Tried resetting the ROM, tried installing other custom ROMs (X-Note, Omega, etc). Nothing seems to work.
Currently I'm running Omera v20, with *zero* applications installed (including all the Google and Samsung applications beyond Google Playstore) and all external services (location, WIFI, et-al) disabled, my note 3 is still 95-99% awake, and the list of wake lockers is, errr, empty.
FWIW I'm ~100m from the nearest cell tower.
EDIT: According to battery meter, Android OS is keeping the phone up.
Any ideas?

Indexing your external SD maybe?
You could try the link in my sig and try again for your custom ROM.

First, thanks all for taking the time to answer.
I'm thinking about getting a new battery, but my gut feeling is that its not the source of amazing battery drain - ~20%/h while completely [!] idle (auto-sync/location/etc completely off).
I've attaching /d/wakeup_source in excel format sorted by count and total time - in-case someone has any idea what's completely broken.
As far as I can see, qpnp-vadc-ebd30a00, sec-battery-monitor, mmc0:0001:2 are the main culprits.
nicholaschum,
Before I attempt a complete wipe (as opposed to the normal wipe data / cache), how can I detect if someone is indexing my sdcard? (which may account for the mmc0:0001:2 in the wake lock dump).
- Gilboa

I know this is a long shot but try turning off developer options if you have it turned on(especially force gpu rendering). Somehow I found out that when I turned it on and the screen is idle. I get a battery drain. Not as big as yours. But not really sure because if I use the phone, the battery is actually pretty great(an hour of screen time is about 10% even more with internet apps like facebook youtube chrome etc.).
Clear cache. I know this is too common but it actually works for a lot of people.
Lastly, try airplane mode overnight and see if it doesn't drain. It might be your network that is causing the drain.

Hi, basically just check your phone using BBS (BetterBatteryStats), and see which individual process is eating up your battery.

Already installed - together with WakeLockDetector.
Short update, out of pure desperation I completely wiped the phone (including sdcard), tried installing stock ROM and, err, Odin failed. Managed to get CWM running again and installed the latest CM nightly.
...
As weird as it sounds, going from NF4 based ROMs (including stock) to CM nightly dropped to idle battery usage to ~2-6%/h, a huge drop from ~20%/h.
I'll update and mark resolved if this situation holds (crosses fingers).

I heard there were problems with NF4 battery. But I haven't been on TW since ND4. No matter what on Note 3 TW the battery sucks. AOSP is great. But actually S5 port has the best battery.

Solved, at least for now.

I use Nova (and not TW)
Either way, latest nightly seems to solve the battery drain problem completely - using the same Nova and system configuration (widgets, active syncs, etc). Currently I'm at ~1.5-0.8%/h when idle with no issues going into deep sleep.
Seems that my specific model really dislikes NF4.
Thanks again for trying to help.

This thread has been quite helpful as I was suffering with a Battery Drain after the NF4 Upgrade.
Planning to go back to ND5, which was the last stable version.

I was thinking about doing the same, but in the CM 11 runs circles around both NF4 (duh!) and my previous ROM (not sure which revision it was) - plus I can actually get 2 days of standby time, even with the old batteries, so I'll stick with CM 11 for now.

Android OS consuming huge amount of battery

hi guys first of all i apologize for this post not having detailed info such as ss from BBS,GSAM and WLD and will post them later !!
and as always i guess with most battery related problems it happened suddenly and i really mean suddenly the day before yesterday everything was perfectly fine and i didn't have that ridiculous battery drain !!
i woke up yesterday only to find out that Android OS is taking more than 50% of battery usage with a drain like 20% over night
restarted many times and by the end of the day i installed GSAM and WLD (wakelock detector)
froze most of apps including the ones i installed recently but i didn't install that battery hog apps (nothing unusual) and also they didn't appear in partial wakelocks section of BBS
btw i don't use any fake battery extender tools or memory boosters it's just Greenify
i observed that sometimes when i unlock my device (i use knock code btw if that matter!!) wifi gets disconnected and reconnect again (wifi icon disappear and re-appear again in 3 secs or so)
i'll upload ss in a couple of mins
thank you
Edit: SS Added
and notice how it drained 5% in just 40 mins (20 mins SOT) !!!

I already tried most of all roms, kernel, try all cpu governor.
If you want to see my topic : http://forum.xda-developers.com/lg-g2/help/lg-g2-d802-battery-draining-5-0-2-t3256313/
If you are ready to dismantlle the phone, do it, and see if there is a problem inside. I hope you will resolve your problem and tell me if one day you gonna have a better battery

yea almost identical problem
i did tot reinstall and see how things go !!

sadly nothing changed and wifi still eats huge amount of battery idk how did this happen
well i'll update thread if anything changed
peace out guys

I had the same problem with battery drain(although not as severe) along with huge data consumption when using a significantly modified(i.e. heavy debloat and ota disabled) rooted stock rom. I tried a few customs roms and dorimanx kernel(not at the same time), and even though battery drain wasn't as bad, they were are waaaay to buggy to be used everyday(especially the dorimanx kernel, it's really bad).
Just last week I tot back to KK and ota updated to the latest LP rom(lost root unfortunately). Then I uninstalled/disabled every app I could/needed. Everything is very fast, smooth, and stable again. I now lose 1-2% every 8hrs in standby with syncing and wifi/data enabled, bluetooth and nfc disabled. I regularly get 5-6hrs sot over 48hrs with moderate use and brightness on auto.
I do have a new battery though - my old one( came with my "refurbished" phone from freedompop) gave me 2-3hrs of sot - but that was when I first got it and before I started modifying anything.

How is dorimanx kernel bad? How many user downloads he has,lots and lots then are we thousands of user wrong using a bad kernel, come on . Maybe it didnt work for you. But out of those thousands of users cant be wrong. If it was that bad no one would download. Just saying , you should just say it didnt work for you.

Can you tell us what app have you uninstalled and disable ?
What have you debloat ?
Thank you very much

My G2 (vs980) has also been suffering from a sudden battery drain. Android OS and Android System seem to be the problem. They are now second and third on the list of battery usage, after the screen. Before now, they were never that high on the list. I noticed this last weekend, when I kdz to the latest update for the vs980, which is 3AA. After noticing this, I flashed the xceed kernel, then cloudy with dorimanx kernel, and the battery drain continued. I even kdz back to kitkat, still the same, then I flashed AICP 11, and still the same battery drain by Android OS and system. Finally, I restored a backup of stock lollipop 39A but, the issue continued so I turned on airplane mode and it seems to help a bit. I still notice battery life isn't the same as before. The os and system still drain more than usual even on airplane mode.
Kind of glad to hear I'm not the only one with this issue. I don't think I need a new battery, since I bought the phone new in April 2015 from Bestbuy.
Also Gsam, shows the temperature of phone between 80°-90°F, where before it would be in the low to mid 70s. One time, it even got up to 104°F, funny thing is, it doesn't even feel that hot in my hand.
Hopefully, we can find out what's causing this because I really liked the battery life on this phone. Even when people complained about the battery life being worse on 5.0.2, I was pretty happy with it. All my previous phones can't compare to the g2. Now I feel like upgrading though lol.

When I tried the version that was out a month or two ago it wasn't nearly as smooth as stock, even after conservatively messing with the kernel app settings. The worst was that it also cut out tethering and my flashlight when the screen shut off. Maybe the recent updates have fixed some of the issues, but I doubt it. Could be that he doesn't have access to the sprint variant which I have...
Either way, just because 'thousands' of people use it doesn't necessarily mean that it's good - 99.9% of those users have no idea how to code or how a kernel is written. Their knowledge goes as far as following picture guides online - which a 5 years old could do. Just look at the most recent change log - those 'fixes' were to glaringly huge problems that shouldn't have been made in the first place and people were blissfully using it the whole time. Think about how many thousands of other bugs their must be. Not to mention hacking up code made by professionals at huge companies could lead to many other problems. Obliviously the stock kernel has bugs as well, but it works and is fast and stable so I see no need for using a hacked together kernel made by one amateur that doesn't even have my version of the phone to test it on. I wanted it to be good - which Is why I went to the trouble of installing it, but it's definitely NOT.

I uninstalled ALL of the stock apps that can be uninstalled. The ones I disabled are aosp keyboard, app updates, browser, calendar, cloud print, favorite contact widget, google play books, games, movies & tv, newstand, google+, lg voice command speech pack, music, music(the widget - it always runs in the background even without being on the homescreen), notebook, polaris viewer, quicktranslator, swype, talkback, voice command. I would have liked to disable a few more but I'm not rooted so I couldn't.
I use nearly all of the google products like chrome,gmail, calendar, docs, keep, music, photos, news and weather,translate,etc...so having the stock lg ones enabled was redundant. I also only have the bare minimum of installed apps that I need. Nearly all of them are made my major corporations i.e Chase, BofA, ebay, paypal, freedompop, microsoft, swiftkey etc. I have NO games or any small apps that need a ton of permissions. The only small apps are feedly, print hammermill, privacy flashlight(240kb, no ads, no permissions) and bubble level(180kb, no ads, no permissions).
I also go through every settings in every app to make sure it's what I want. And I restart my phone every time I take it off the charger. IMO having a clean and no frills system that is set correctly is the key to performance and battery life.
I just want want to clarify that I average 4-5hrs per 1% in standby since it doesn't seem to hold as well as it gets closer to 0%.

theres this app that have lots of info on battery..

thx guys for adding your experience
i hoped moded kernels would've reduced that amount as they should have necessary drivers for wifi which was somehow got messed up but from your reply i guess i've to look somewhere else

idk how to put this, well this isn't a solution at all i actually didn't start working on it yet just thought to share what i found so far !!
so it's just a reference for any one whose luck was bad enough to have a wakelock like that !
1st of all in most cases neither the device nor it's battery are at fault *you need to understand that*
faulty battery doesn't show up kernel related wakelocks instead they drain without a reason so i hope ppl stop accusing battery in every battery drain thread!
2nd after understanding that you'll have to deal with the environment your phone is used in
to put it simple it's your router and all devices in your current network !! (idk though why not all devices get affected by that or why it just started now, tough luck yea)
those threads may help

http://forum.xda-developers.com/google-nexus-5/help/getting-rid-wlanrxwake-wakelocks-t2519294
what i'll try to do is add an old access point to my router and connect my phone to it as i don't have a replacement router right now!!
i'll let you know if things were improved !

hey guys
i thought to share what i did so far and before i go on there is a bad news and a good news !!
i would start with the bad news first !
-no rom could solve this issue so you don't really need to format everything and start from scratch especially if you didn't mess around too much and you found it started suddenly like here, i've tried couple of roms including latest CM13 build it wasn't that bad but it didn't solve the drain that much either !!
-now some ppl may see this bad and some may don't care (which means good!!) google services are the ones responsible for this drain
well man you didn't come up with anything new and i see you've got a problem getting straight to the point besides you talk too much
i'm sorry
now you have to sacrifice your google services background sync including "GCM" if you are using any services similar to pushbullet or notification mirroring you'd understand why it's important
anyway if you are good with that you may install and yea it works with latest google play services
https://play.google.com/store/apps/details?id=com.playfulgeeks.gservicefix
and do as instructions (and believe it'll work if you did steps right)
if you prefer manual way then you'll need "app ops xposed module" and deactivate every "wake up" permission from google services
this guide may help but remember we don't have tools natively in our roms so don't bother downloading "shortcut maker" and go through your settings app to find "privacy guard" or "app ops" we don't have those natively like them
http://forum.xda-developers.com/oneplus-one/general/guide-google-play-services-battery-t2832525
i'll share some ss from stock battery stats
i'm sorry for my long post and i hope it'll help someone with same issue
idk if it solved issue completely but things are stabilized a lot now and i just lost 1% over night not 20% or 30% like before !!
and i'm using lollipop now so i guess it's not that bad for what i heard about bad lollipop battery since it's my first time trying it !!
and btw real SOT should be +40 mins so the real SOT is 2H-47M cuz i restarted my phone to apply that fix and for some reason battery stats doesn't stick between reboots !!
if anyone interested in trying that rom it's for D800 only btw and thx to @Swetnes for his work rom feels pretty stable and solid :good:

BUGS & BATTERY USAGE on JULY official rom

hi MI A1 owners.
for those brave enough to use the latest vanilla, official OTA rom, what change did you notice?
does the battery still suffer huge drain that appeared in 2018 roms?
it's a big "NOPE" for me to update, i'm still on official DEC rom because of this drain issue.

Battery life is good on 8.1 no issue for me getting 5-6 hours SOT on gaming.

Never had battery drain problems. Only "issue" is notification led not blinking.

Just noticed that led light is no longer blinking when notifications arrive. Light stays on only when screen is off. Also Bluetooth is constantly disconnecting.

Ambient display isn't working for me.
Led notifier is also not blinking anymore!

Led not blinking, proximity sensor doesn't work properly all the time, some scrolling lag. That's what I've got so far

dudes thanks for your answers.
i'm just more convinced to not doing the update.
maybe the drain i had was magisk-related. (?)

Nothing for me, even got ten hours of screen after some cycles. Led doesn't bother me and it's the only thing i noticed.

Yes, the LED is always on, which is annoying, but the bigger issue is there is no change in the battery drain. I charged to 100%, set the phone down and did not move it or use it overnight. 8 hours later almost 14% of battery was drained. I have tried everything I can think of to try, including turning off high accuracy location, not allowing any location things like safe area, etc. and still I get this drain even when the phone is not in use. Android kernel and system consumed 85% of that usage, and System UI, Play Store and Phone Services accounted for 7%! SO basically, basic Android paired with the A1 hardware seems to be the issue and I don't know that there is any fix for that.
At one point, I thought an upgrade to the A2 was going to be a no brainer, but with the issues with updates being broken and this battery drain issue that nobody seems to be able to pinpoint and resolve, I am thinking I may not buy ANY other Xiaomi. It may be time to try something else because the only way I can get two days of battery is to turn on airplane mode when the phone is not in use!

Dunno what to say man. Mine is below.
2-3% at most over night.

And now it would appear that there is an issue with airplane mode.
I put the phone into Airplane mode at 2300 last night with 90% battery and did not pay attention to it. This morning I turned to phone on to find there was only 69% battery left, and WiFi was working. (see screen shot) WTF???? I have started using airplane mode to keep the battery drain to a minimum when the phone is not in use, and now it would appear that this doesn't work either.
I am REALLY getting frustrated with Android and Xiaomi as it seems that every time they do an update, something else goes bump! I have gone from totally happy with the AI when I first got it to being ready to write off Xiaomi as a company I would consider for purchase.

Is your WiFi scanning is on. ( Under location / scanning)
Play services also cause these type of sudden battery losses.
Try downloading latest play services apk from apkmirror . Latest one is
"com.google.android.gms_12.8.74_(090408-204998136)-12874034_minAPI26(arm64-v8a,armeabi-v7a)(480dpi)_apkmirror.com.apk"
Uninstall your current one. Install this .
Power off your phone for a few seconds and reboot.

Thanks for the thoughts, but unless I totally misunderstand what airplane mode is, WiFi should not be active when airplane mode is invoked. You can see by the screen cap that airplane mode is on AND WiFi is active. This seems to be a one off as it has not happened again for the last two days. I turn airplane mode on to stop the overnight battery drain while the phone is doing nothing. I have location set to GPS Only. IIRC play services was just updated 3 days or so ago, so it should have the latest version. I will check it and see though. Again, thanks for the thoughts.

I can't logically understand why you would think it is the hardware causing the issue. If it was hardware, what you are seeing would be happening to every owner of the phone and clearly that is not happening. By saying it is the hardware when you have other software loaded is akin to saying your car's air conditioning doesn't work properly when you have all the windows wound down.
There is something loaded on your phone that is causing the systemUI to be working when you think nothing should be happening. The first thing I see on the screenshot on your phone is that in the top left of the screen you have two non standard icons. That tells me that you have a skin or non standard software constantly running.
The way to solve any issue like this is to go back to basics. I would get the fresh rom and do a Miflash whilst keeping your data. Make sure you do a backup first.
If that does not work, back up your data and do a clean install and check the phone's battery life. Do not load any non google software / app at this stage.
Then each day add one app and test for 24 hours. You will find this issue and the offending app or apps and I would be willing to bet you a few Singhas it will be an app you downloaded not the hardware causing this.

Actually, I think it is a combination of hardware/software, but that is just a WAG. Others have noted the exact same issue without running the same software. My bet would be on the RCS services stuff.

Those icons are my Email client and GSAM Battery Monitor (presently 0.1% and 0.8%) and are the only two constantly running programs other than the stock apps and Sophos (0.3%). Neither use much battery compared to the Android stuff. Presently Kernel is 41.6%, RCS/Phone is 30.3%. SystemUI is 3.3%, Play Services is 2.0% and Phone Services is 1.8%

Good advice. I will do this when I have a few days to play with it. In the interim, it's airplane mode every night. Thanks for the reply. If it turns out to be one of these apps, let me know where to send the Singhas.

Good luck with it. I hope you find the solution. It can be frustrating, but getting to the bottom of it will be worthwhile. I haven't used Sophos for a long time and even then it was for PC. I am not up with how Sophos AV is integrating into Android but that would be my first guess.
I have only had one issue with this phone after updating and it was that the OS was constantly asking for a password on unlock after using fingerprint not just on startup. A clean install solved it and I have been trouble free since with every update. With over 50 PCs in my office, I could only wish that I had so few issues with Windows updates as I do with Android.

For me, night light auto schedule not working properly.

I can't tether via wifi/bluetoth/usb
Made another post with the problem.

Just for grins and giggles, I uninstalled my email client, GSAM, and Sophos, the only programs that run constantly other than system and Line. I then turned my phone off and back on, forced stopped Line, charged it to 100% and set it down with the screen off. It did not move of get used for 8 hours, yet it still used 12% of the battery. (see screenshots) This is better than the 20% with those apps installed, but still not close to what I would consider normal. When I first got the phone, it easily lasted 2-3 days between charges, with 6-7 hours SoT. Overnight would use MAYBE 2% of the battery. Now if I want it to last 2 days I need to turn on airplane mode overnight and then I can make it through a day.
So I guess the next step is to do as you recommended and load up the fresh rom when I have time to mess with it. At least I am now pretty sure that those apps aren't the culprits causing the biggest part of the battery drain. I hate to do it, but I am seriously thinking of a factory reset and seeing if that clears the issue. Would that put me back to Nougat?

So those apps were causing 40% of of the 20% of the battery drain. That is a good start. I am confident there are software issues with your phone. I see you have some GPS app on your home screen, if that was running askew, it might be constantly pinging. That is just a guess.
In things like this, work methodically through it. But of cause a hard reset would be the best way to go. I see no reason why you wouldn't stay on your current version after a hard reset.
If you want to go make to version 7 you would need to use the MiFlash program and a downloaded standard fastboot rom. You may need to do something else to the phone to go back to 7, but I would not think so.
