Android System Process battery drain sense kitkat (4.4.2) update - Nexus 4 Q&A, Help & Troubleshooting

Has anyone had issues with really bad battery drain on newest update?
Sent from my Nexus 4 using Tapatalk

I haven't noticed a drop in battery life after upgrading from CM10.2 to stock 4.4.2.
I have very few apps on my phone and I keep wifi and data off when I'm not using my phone.

It was my GPS eating up my battery. Mixed with the weather channel app. My battery was dead in 7 hrs.

Bad Battery Life
Hi
Yes, I have noticed a dramatic drop in battery life. I use to get home from work about 6pm with about 50% battery life. Now by 2pm I'm less than 10%.
No Bluetooth. No GPS. No NFC (this was originally on when getting to 6pm). WiFi on. WiFi Off. Doesn't matter. Turned location services to battery save or off. No new apps.
I have converted runtime to ART (worth having a read up on this), which can potentially give up to 20-30% better battery.
The funny thing is at home with full WiFi and strong 3G reception the battery life is exceptional! 2-3 days standby (light/medium use). The 3G reception at work.
A friend suggested that possibly the radio (3G) isn't locking on to a specific tower and keeps bouncing between towers chewing up the battery.
I will try a factory reset and see if it fixes the problem. From what I've been able to discover online it doesn't seem to be a very common problem.

Same Here
My girlfriend is having the same problem with battery drain.
GPS is off and she's using Wi-Fi at home.
When Google rolled Kit Kat OTAs I had to wipe her phone and flash the official Mako factory images to actually get it updated. So the phone isn't rooted and It's completely stock now. The 4.4.2 OTA update installed just fine. Then she noticed the poor battery life. Android system and Android OS are the 2 highest battery users in the list (will try to get a screenshot of this later)
Is the factory reset working for any one?
Has a reinstall of the factory images fixed this?
Any other suggestions?
Just wanted to ask everyone before I spent a bunch of time on it.
Thanks so much!

factory reset doesn't resolve
I did a factory reset and the issue still exists. I have removed 1/3 of my apps, 80% of the photos on my phone. I tried running Bluetooth off 100% of the time. Turned off location reporting. Turned off syncing any Google service I wan't using. None of these helped. My problem is intermittent. I will make a change then go a couple of days thinking "problem solved," then on the third day massive battery drain reoccurs. I think the battery monitor in the OS is unreliable when this occurs becasue it will report an app like "Flixter" as the main source of the drain. The next time it will be mediaserver, or TV Guide.

You got a lot of apps it sounds like. My problem has been eliminated sense removing weather channel app. Been good for two weeks

Same problem.
I have read millions of forums and this problem is not going away. I also have intermittent battery drain - it works for a few days and then everything goes back to sh-it. I've tried everything - deleting apps, turning off all services i don't use, power saving mode, sync, GPS, and nothing works.

Thanks for that note! I know my gf uses the weather channel app. Will tell her to remove it.
On a similar note. Now a few months later now and her battery wont hold a charge for more than 2 hours and wont charge to 100% every time. Her phone is only a year old. luckily she called google 2 days before the 1 year warranty was up. They sent instructions on safe mode and some other tips. Hopefully she'll end up with a new battery and i'll make sure shes not using weather channel haha.

OTA battery drain [XXJVK]

Are you having high battery drain with XXJVK firmware, or any other 2.2.1 firmware?
Does your Battery Use shows high CPU usage time on Android OS?
Then, check if you ever had Software Updates logged in! I noticed high battery usage once I logged in for OTA updates. Possibly, the device is retrying the connection to update server (which will always return timeout). You can see the Software Update service running all the time once you logged in.
If you have logged in Software Updates, go Settings->Applications->Manage Application->All->Software Update->Clear Data
Once you have logged out from Software Updates, the service disappears and personally, battery life doubled.
Thanks, i will try it!
It really could be the last chance to solve my idle-drain-prob.
i'll report back.
//edit: cleared data, service automatically stopped. i'll report back tomorrow if it solves my drain-thing.
Yup i had it running too since boot.. cleared data and will report back
Let's hope this is the answer. I've just took the drastic measure of doing a hard reset and now battery drain is pretty much zero and phone is idle when screen is off. I'll keep installing and enabling things and see what takes more battery.
Very interesting, I did check if there were any updates, and I suffered from random battery drain. At first I suspected Google Maps/Navigation, but you could be right. I started Maps, and Navigation, killed en cleared OTA, and I am monitoring the battery.
I have found that when i use the built in task manager to "clear memory" as soon as i have done that the battery drains alot faster and my android OS in battery stats goes through the roof (from 5% to something like 14%). It has been running fine since yesterday and i cleared memory only to find my battery went very quickly from 28% to 9%. I rebooted the device and all is well, i wont be using that option anymore
After installing jvk full I installed jve modem, rooted and did battery stats wipe and battery issues went away.
i lost 25% over night in airplane mode
background & sync = off.
after clearing dalvik cache & battery recalibration using battery calibrator from market i have 5-7% drain per night, and 30-40% per day... last battery time was 2d 19h 14m, with some calls, some games, some wi-fi and some hsdpa & with weather widget update every hour.
info
i9000 + JVK (repartition 512, with bootloader) + CF Root
P.S before clearing dalvik cache & battery recalibration with same use i have maximum battery life - 23h
Clear the data for "Samsung Account".

There's something very wrong with your phone, either your battery's shot or there's a rogue program draining it, you shouldn't lose more than 1-2% overnight in airplane mode.
Same problem here. I hate this device...
Is it just me that think battery life is much better than on froyo?

I have no battery drain since i upgraded to jvk.
Sent from my GT-I9000 using XDA App
I'm seeing huge battery drain like others, sometimes more that 50% in a few hours doing absolutely nothing, wifi & 3G off and OS takes up to 60% of the battery usage. I never activated Automatice Updates since I flashed JVK. I am now on Darky's v10RC3. Only a few people are having such problems, most users say they are experiencing their best battery life ever.
I noticed that this drain always happened to me after I used Maps / Navigation. So I suspect them to create problems, maybe kicking off Software Update in a bad way. And rebooting stops the drain (it once took as long as a full flash for my phone to reboot...?).
So I have bought for $1 this nice app called Autostarts that shows which apps autostart, what triggers them to start and it is then possible to disable by app / event.
When I tap on Software Update, I can see that it kicks in on these occasions:
- After Startup
- Application installed
- Application removed
- SMS received
- Secret code entered
I disabled everything as well as for Map, so now it's no longer showing in running apps / processes.
Will follow this thread !

Spot on.
My Android OS battery usage is down to 3-5%.
Great find guys, Thanks a lot!
Also, a little suggestion here but I need someone to confirm.
Regarding Google Maps, I was having some trouble getting rid of Hotpot and Rate Places processes as they were constantly running for no reason and restart after I kill them. Another 13% drain. So yesterday I updated to Maps 5.3 and the processes are no longer there even though I've used Maps, Hotpot and Places
I upgraded with odin, repartition and bootloaders. Since now the battery life is very good, i can see the difference by eyes.

[Q] Serious Battery Problem

Just this week my phones battery has lost its mind. I use a my touch 4g with the standard battery and had a usual battery life of 12 hours or more easily. Now from this Tuesday I've had a battery life of 4 hours from 100% to 0%. I have to charge the battery 3 times a day. Most of the battery is used when idle for some reason and I've looked at what uses the most battery in spare parts but the app will constantly crash.

I'll tell you what's funny. Is my mom and i have the same phone and we are having the same exact problem that you are mentioning. In fact i have Auto Sync off / GPS off / data ON /and i've lost 12% of my battery in the past 3 hours. My battery usage stats don't look that off. but something is seriously going AWOL.
same issue here on 2x phones.. These seemed to correspond to the radio upgrade i did from the official gingerbread release.
I have since backed out of it, going back to the previous version. However, the issue has seemed to continue.
I have done the following (prob didn't need too, but wanted to cover the bases)
* Wipe cache
* wipe dalvik
* reflash rom
* apply kernel update
... I seem to still be experiencing the severe drain, phone is hot..
I did just notice the cell tower GPS was turned on, i disabled this to see if it helps.
Next step will be to remove the market update i recently did that also corresponds to the problem.
Other then this... i'm at a loss as to wtf...
I updated my radio this morning but I was experiencing the problem before the update so I don't think it was that.
I had that same issue when I updated to the newest radio...ate my battery up like a fat kid in a twinkie factory! So I went back to .09.04, wiped battery stats, calibrated battery with the app, and now my battery life is getting back to normal

Clearing out and resetting gps seems to have yielded positive results on both phones.. battery seems much more stable on both phones

I was thinking about this last night. t-mobile knows what phones we have by IMEI numbers. And since they are pushing the 2.3.4 update out. I wonder if they are pinging our phones trying to get our phone to accept the update. And since we aren't running a recognized ROM it's sending back the information the computer is wanting and thus the cycle continues. Killing our batteries.
Everything on my phone right now is stock and the battery still drains like mad. Last night I left the phone idle at 100% and by my math I was losing 5% every 10 mins so by the time I finished watching two movies without even glancing at the phone my battery was dead. Now I notice that the phone takes about 5 hours to charge as well.
I have been experiencing the same issue since Wednesday. I've wiped, reflashed, changed from cyanogen to virtuous unity. Nothing stops the drain except putting the phone in airplane mode. There is a pretty serious discussion in the t-mobile support forums where a lot of people, both rooted and not, are experiencing the quick drain. It seems t-mobile has acknowledged this to an extent but hasn't issued any statement with any clarity as to why or when it will be fixed. One thing is becoming more apparent though and that is that it seems to be a network issue. Some people have removed google maps and fixed the problem but that didn't work for me.

I posted this in the RG2.1 thread. I have had this fix the drain issue on 2 phones. Please try it, i'm anxious to see if it works for others.
My phone was getting hot near the bottom of the phone, i believe this is where the GPS chip is.
I only have theories as to why the gps could be the issue...

By Putting the device in AirPlane mode you are bypassing the HSPA network. and cutting all ties with it. There HAS to be something pinging our phones. HAS to be.

airplane mode disables ALL of the radios, including gps...
I seriously doubt something is pinging the phone. I don't believe the update check works like that.
^^^^Just tried the above method to no avail. Battery % just dropped another 3 percent in about 15 minutes. This issue seems to be spreading fast. I proudly consider myself a geek but I am stumped as far as knowing what to do. I guess we are at the mercy of t-mobile.
Interesting..... I've noticed the exact same thing the last few days. Normally when I'm at home and my phone is on wifi, I can go to sleep with the phone at around 95% and wake up in the morning and the phone is at around 91% or 92%. Wednesday I woke up and my phone was at 63%, I was shocked. I'm running Royal Ginger 2.1(I've been running it for some time now). So something has changed and I personally don't think it's the ROM. The suggestion about the official gingerbread update from tmobile seems like a pretty good assessment considering its been happening to a lot of people (rooted and non rooted) over the last week.

I had the same battery drain problem for the past few days also. I saw an article on another site about recent battery drain problems for a different T-mobile phone. (i think it was the G2) A few ppl on there named a couple apps that they thought were causing it: the recent Google Maps update, the Market update, and the Google Plus app. So I uninstall the two updates and the Google+ app, let my phone die completely and charged it all the way, with the phone off, uninterrupted.
That was 19 hrs ago and I have 60% left and I've been browsing the web, with wifi on, and playing a few different games for most of the day. I don't know which one of those things fixed it, but I had to be one of them. Before this I was lucky to get through the work day with more than 20% left with little use. Hope this helps some of you fix this.
I was having the same issue and clearing the gps state as mentioned above seems to have worked.
EDIT: This did not work. I was out in a gsm only area so my phone was running on 2g and as soon as I got back to HSPA+ area battery drain started happening again. Might be going to Verizon if this keeps up.

[Q] Major Battery Drain after flashing Lollipop

Hey there!
I flashed the official Lollipop (Germany) rom that is posted in the Note 4 General forum two days ago without doing a factory reset. Right now, I am experiencing horrible battery life. GSAM reports that the phone radio is using 35% of the battery life. I also see the 4G icon blinking every few seconds, indicating that mobile data is being used. How can I solve this? My battery life was perfect before flashing Lollipop...
Many thanks in advance!
Screenshot just in case:
Maybe you should try a factory reset.
Although I updated without resetting and one of my friends did a full wipe before and after, and we both see a decrease in battery life. Nothing too horrible, but noticeable. So I think it's just Lollipop. After all, even the Nexus devices have been having battery issues with it.
See if a factory reset helps you, worth a shot.

Thanks for your advice. I will be sure to give it a shot. A decrease in battery life is pretty bad if you ask me. I thought Project Volta was supposed to improve battery life, not decrease it. And definitely not as much as is happening to me. By the way, the phone radio is still constantly active. I hope a fix will be out soon.
Can you check your Power Saving menu? I have similar problems with all apps that are using mobile data. Their Total connection time is really long even though I have used them for a few minutes.

Unfortunately a factory reset didn't help. My battery is still draining way too fast.. I can get around three and a half ours screen on time. Previously that was around five hours. I will check the total connection time later on when my battery has drained a bit!
Horrible battery drain in my handset, too. 910F model with German rom.
Flash echoe lollipop rom.waaaay better then stock.no more battery drain for me and much faster!
Formating cache partition helped me to get rid of the battery drain.

That sucks. It seems like this is a very serious bug in Lollipop. You'd think Google would have it figured out in 5.0.1 but that doesn't seem the case. Very annoyed by this.

here the same battery drain of facebook after lollipop upgrade (germany)
when i unplug wifi it starst keep stay connected to facebook and it grows even bigger than screen battery consumption.
heve you fixed it?
thanks!
I found WiFi to be the culprit for the rapid battery drain on Lollipop. Check out the following posts with my observations so far:
iridaki said:
After updating to Lollipop, I found that the phone behaves very differently. I have high "stay awake" times, caused by Android OS, even on Ultra Power Saving Mode. However, screen on time is still close to 4 hours, which is what I was getting on KK with my usage.
Before people jump in and say I need go factory reset, no I don't, there's another Note 4 in my home right now that was wiped before and after the update and shows the same symptoms.
Also I did install Gsam, but I'm not rooted, so it didn't give me more information than the stock battery stats page.

iridaki said:
UPDATE: I think I found the culprit. It's the WiFi. What I did today was charge my phone to 100%, switch WiFi off, disconnect from the charger and reboot. Then went about using it as usual, only I didn't turn WiFi on at all, not even for a second (weirdly enough, the battery stats report WiFi being on briefly at times, but that's another Lollipop bug).
The results were a big increase of SOT (+1 hour, see my previous post for comparison), no more permanent wakelock and increased standby time.
My findings are consistent with reports from Nexus users, claiming WiFi on Lollipop is a battery killer, even on 5.0.1, which was supposed to be an update to fix said issue.
Now, not turning on the WiFi is not really a viable solution for me, as I don't have an unlimited data plan, so I sure hope Samsung will fix this problem soon.

Below are screenshots showing battery behaviour with WiFi on (first 3 images) and with WiFi off.
It's important to point out that simply turning WiFi off doesn't appear to bring battery drain back to normal.
Turning WiFi off and rebooting fixes the issue, so long as you don't turn WiFi on again.

LOLLIPOP
I've started to have very poor battery life 7 days after installing the DBT lollipop. 60% after 4 hrs use today. It was good at first but has been getting worse by the day. Something was making the phone get hot just now so restarted and its cool shortly afterwards. However I cannot identfy what it was causing the overheating.
Is it worth trying to wipe the cache? I did a factory reset after the install as it was boot looping. I really do not want to reset it weekly! Google is crap at backing up all the apps - 160 out of 196 were reinstalled after the factory restart. Very poor.

Need advice about battery drain

Hey everyone, I purchased the 6P a week ago and I really don't understand the battery in this thing.... I'm coming from LG G3 which never faced battery drain during stand by. I am not even using the 6P (still haven't migrated from the G3) because of the unreasonable battery drain during sleep, I have WiFi always on and (no I don't accept to turn it to Never during sleep) I never did this with any phone anyway, my G3 doesn't lose more than 1-2% during the whole night (7 hours).
Please take a look and tell me if this makes any sense because I'm thinking of returning the thing if it's not just a software issue:
Time of screenshots:

Taken today, phone left untouched at home.
Battery life is really hit or miss, many lose 0-3% during the night while others like yourself lose a ton. Try changing your WiFi to either 2.4GHz only or 5GHz only, as some found that helps out. Custom kernels can also control WiFi wakelocks, and I've found running Franco kernel does a great job at helping standby life.
How's the signal strength from within your home? Having a weak cell signal can assist in battery drain. However that's some serious drainage. I'm thinking you have one or more wakelocks preventing the phone to deep sleep. If you're rooted, greenify is a must. It has boosted my battery life by a ton. I would also try to get some more battery stats applications. Better battery stats was/is my favorite app but I'm not sure its working on MM

Although it is not convenient to switch between the 2 bands ( Work is on 2.4GHz and Home is on 5GHz) but I will try it to see if it helps any.
Do you think this will be fixed with software update? and is it because Android M or because 6P on Android M?

I would also try to get some more battery stats applications. Better battery stats was/is my favorite app but I'm not sure its working on MM

Signal strength is fine at my home ( never faced an issue with G3).
I haven't installed anything that can hog battery like that, I only set-up Email, Hangouts to Sync, I never used Greenify or any battery saving apps ( The battery should last as advertised with it's standard capacity), i'm not asking for a magical battery life, just what's expected of a 3450 mAh.
I'll post Sambatterystats results shortly.
See if WiFi scanning is turned off
Many say the battery drain issue really spiked with the update to Android 6.01. So it appears to be SW related, and not HW, FWIW.
I found my fix is as Geoff53 said above, install a custom kernel (Kylo in my case). And I use Greenify on top of it. Great battery life now.

I hope it's just the 6.0.1 .. because I really would hate to return it..
Well, I'd go as far as flashing a custom ROM if that would completely solve the problem, not just the Kernel.
I initially had bad batter drain, not now. Unplug 6:30 am and 10pm still have 45%. Use to be dead by 7pm. I found the culprits were bad apps that I thought were OK. Ebay, Amazon, Facebook, ESPN, Waze.... when I deleted these and a few more, then rebooted all was good. Haven't tried putting them back though. I leave GPS, WIFI, blue tooth... all on. Even have 3 mail apps all set to "push." I don't twitter though.
Make a back up with Titanium or MyBackup, factory wipe and reset and see if your battery improves with only basic apps and mail. Bet it's bad apps. If improves slowly add apps until you find the culprit.

In my opinion, the " Bad App" theory is getting a bit out of hand. I installed the same apps as on my G3 (never had a bad app on it) , and 6P has been factory reset and insatlled nothing at all, only logged into gmail and hangouts, and I tried with the (WiFi during sleep set to never ) then the drain is not as bad anymore but I lost realtime push notifications which is unacceptable.
Now if believe there are so many "bad apps" then we can have the Doze which is supposed to minimize app drain if not terminate it, but that's not the case here obviously, so I think it's actually specific WiFi bug on Android M and not bad apps.

This for me, was getting lovely life and slooooow standby.
Updated the latest build yesterday and Google Services has hammered by battery today, gonna give it a few days to settle down though

Hey everyone, I purchased the 6P a week ago and I really don't understand the battery in this thing.... I'm coming from LG G3 which never faced battery drain during stand by. I am not even using the 6P (still haven't migrated from the G3) because of the unreasonable battery drain during sleep, I have WiFi always on and (no I don't accept to turn it to Never during sleep) I never did this with any phone anyway, my G3 doesn't lose more than 1-2% during the whole night (7 hours).
Please take a look and tell me if this makes any sense because I'm thinking of returning the thing if it's not just a software issue:

did u somehow manage to decrease standby drain?

Trying to track down cause of recent battery drain issue.

Hello all,
So I know there's various discussions all over the web about the Galaxy s10 and battery issues on both Snapdragon and Exynos variants. It seems people are experiencing a wide margin of difference in avg battery life..
So here's my situation. My wife and I both have S10+'s through AT&T. We got them the first week they came out. I looked though the forums and performed several battery optimization tweaks on both phones and since then the battery life has been really impressive... No complaints really. Until this last week.
We both recieved the March security patch and fingerprint scanner fix about a week ago. My wife's phone seems unchanged by this. Everything working as expected. My phone however has been draining battery MUCH faster both in SOT and standby time. I'm losing 2-3x more battery % overnight. In the last 20 mins of just reading through threads on the XDA forum app, I've lost about 10% battery. I'm sitting in the dark with my screen brightness very low too. (down another 5% since I started typing this!)
My wife and I have very similar phone habits. Since both our phones are optimized identically, and we used most of the same apps a play the same games, I started looking through everything different I've done in my phone since this problem started. I installed Adhell3, which seems to be setup properly and working. Mike B. from Adhell's Discord assured me that Adhell shouldn't be draining my battery. I'm mostly using it just to remove a bunch of basic bloatware and block some ads.
The update seems to have worked fine otherwise. My FP scanner is much better now, but something is definitely wrong. I've tried wiping the partition cache afterwards. I've tracked down others experiencing issues after this particular update, but cant seem to find a way to fix this problem yet. I saw something about Deep Sleep problems after the update when someone uses a VOIP service like Skype or WhatsApp, but I dont use anything like that. I can't even find a good tool to use to see more information about my battery usage, as the built-in battery monitor lacks a good deal of information. CPUspy doesn't work on my version.
If anyone has any ideas of what could be the culprit, what else I could try, or what tools I could use to try and track down what exactly is causing this sudden increase in drain, I'd really appreciate it.
Which update do you have ASBA or ASCA? This is rather weird, Battery drain can also come from restoring from backups. I lose 2% every night and my phone is on airplane mode, not connected to anything except location. I do not have adhell, and last time I tested before the fingerprint update I had 10h SoT on wifi purely. When I got the new fingerprint update I checked if the phone went to deep sleep and it does, so I really do not know what might be your issue. I have an exynos variant btw. Also I charge my phone constantly from 80 I let it drop to 40 and charge it back, I do not use fast charging options. Since unplugging my phone now on LTE fully I have lost 1% in 30 min, I have my fitbit always connected, location on, max resolution, I have a semi black wallpaper and brightness around 40-50%.
I will see today how much SoT I can get from 80% part wifi, part LTE, I will update.
clear cache helped a lot of people
Update 1
Reset all phone settings to factory. Don't do full factory reset, just all the settings, fixed my post update battery drain issues

Update 2
Hrrm. It seems I don't have ASBA or ASCA, I have ASD3. The March update.
I'm really hoping I don't end up having to factory reset and manually install everything... Because I did do a restore from backup with AT&T Transfer, because it seemed really convenient and time saving. I had no idea that so many people have had issues with restoring from various back up services (AT&T, Samsung, Google etc.)
I did the same restore from backup on my wife's S10+ too and she's had no problems. Her battery life is phenomenal. My battery issues only started after this last update.

Well that seems rather strange to be honest, you can eliminate possibilities by just testing and see what works. Last possibility can be that factory resetting and installing all new, but then again, it could be that it solves your issues or not. You should be having rather horizontal lines to prove your phone is truly going into deep sleep in my opinion, but also you can check with CPU Spy
Sorry it will be this pic
Try to log too safe mode and check the battery drain
If stopped then it was from an application that have a problem
If not I think it might be a system app or something
So. I'm starting to think that some of my problem has to do with wakelocks. Unfortunately I have limited access to wakelocks statistics since my phone is unrooted. However. Last night I fully charged my phone right before bed and then took it off the charger to see how much it would lose overnight. It dropped a whopping 10% vs the 1-2% it used to.
I looked through some of the battery info and noticed several apps running in the background for very long periods of time since last night. Chrome(2hrs) , Discord(2hrs), Google Play Services(a whopping 13hrs 30mins running in background) and Google Play store (5hrs)
Somehow Discord was responsible for draining 7.6% battery in that time!
So, could this be a wakelock issue causing my phone to lose so much battery overnight? I know that's only half the problem, because I'm also experiencing higher drain than usual while using certain apps too. But I'm trying to figure out one thing at time.

You can look at this thread and see if you can install the app without being root or not

You just need to tweak your settings more, put which apps do not run on the background or go to sleep, how many days you need to wait to put unused apps to sleep. Is all tweaking the settings.

Then I don't what you can do, either do a factory reset and so not restore anything from backups and see if that works. I usually set my phone that way, clean no restoration from any backup all apps are installed manually, and I do not even use adhell to disable most of Samsung crap apps and services.
