Quick battery drain & constant data being sent since 1.78 OTA

Hi,
I've got an HTC One S since a few weeks (got it with the 1.57 FW I think). It's a stock one, not from a carrier. No branding.
The battery life was great, 2 to 3 days with normal use.
But yesterday evening I proceeded to the OTA update and since then, trouble began
Battery life is much, much lower. After 12 hours standing on my desk in the office, I got 10% remaining!
Anytime I switch the screen ON, I see there is some data being sent (or received) because the "arrows" are full. If I check in system panel lite, there's always 1 or 2 kb/s of traffic.
Also, the phone is a bit warm, quite often.
Has anyone else noticed this? That's rather annoying :/

Could be faulty? I have the same phone with no carrier or branding and not had any problems at all.

Like faulty hardware? Seems unlikely to me since it worked well with 1.57. Also, sending data isn't hardware related

Here are some details.
In Mobile usage, just for today (less than 24h)
"Media" has used 13MB of background data
"Android OS" has used 5MB, also background
Android OS gives no more details. Media is told to include "Download manager" "DRM protected content storage" "Media storage" and "Downloads"
This sounds like a lot of background data :/

Try an app called Badass Battery monitor. It should tell you what's eating your battery.

I have to say, this phone, at least mines, seems to have a pretty bi polar battery. It's got a case of ADHD.
For example, just the other day, I had the phone fully charged when I awoke at 9am, after playing Temple Run, surfing the web, using GPS, streaming and listening to music, playing more Temple Run, fiddling around with the OS, checking emails, sending texts, talking on the phone a bit, downloading apps, with about 25-30% brightness, I ended up with 18% battery remaining after a good 11 hours of very heavy use. I was quite pleased, considering the inordinate amount of usage I had with the phone all day.
(BTW, I use Juice Defender, which has helped tons in reducing battery drainage for almost every phone I've owned in the past 3 months, including the One S)
Yesterday, I had the phone charged at 100% when I awoke at 9am, with a little bit of use, by 12am, I had 63% remaining, same brightness, but with much much less use then the day prior. By the time 3pm hit, I was at about 30%, and by 5pm, it was drained to 18%, mostly on standby. By my estimation, that's 8 hours of usage, same brightness levels as the day before, using Juice Defender, but with much much less fiddling around with pretty much everything on the device.
I went ahead and disabled Juice Defender today to see if it would make a difference, and the battery actually got a bit worse, so I went ahead and re-enabled it and it immediately improved.
So I'm a bit perplexed, I haven't gotten any official updates, still running on the original stock build, but ultimately, I guess this is what is too be expected with an early build. Hopefully future updates WILL fix these issues and not hinder them more. Granted it's still much better then my HTC Amaze and Galaxy Nexus, which drained 4% the moment I took them off charger.

Thanks for your input, I'll check again today how the phone goes.
I played with all the settings and menus yesterday, and found something strange. In the "downloads" app, there was a "system update" download. That's quite normal since I downloaded and applied the OTA the day before. But it was referred as "ongoing", like it was still downloading a part of the OTA zip file AFTER I applied it (and rebooted a couple of times)
In phone settings, about, updates, it was also written "ongoing"
Now this is over (I don't know why and how) and the network usage seems back to normal. I'll try today to see how the battery drain is
Anyway, it's s strange the phone was still downloading the update zip file after having applied it. AND that it was downloading it on the 3G at a very lowered bitrate (like background) while I downloaded it on the wifi the day before
Anyway...

The battery life of my One S seems to have declined as well since the update. Before the update my battery lasted 2 days easily with moderate usage. Now I have 20-30% left at the end of the day from a full charge since 9am. This is with very light usage (mostly on standby from 9 to 5).
I did turn on best wifi performance recently so I just to turned that off to see if it helps but I really doubt that.

Hello guys, I have same problem, but my phone wasting energy on "phone radio" process, just look at screens below. I tried using stock Rom with last update, trickdroid, and now it happend on leedroid v.2 . Btw I changed 4 micro sim cards with several providers, but no result. I really need help with this issue, because my battery draining very very
fast...
Thank you

I had a similar problem a few days ago, using Lee´s ROM.
I noticed that the drain had something to do with autosync. As soon as I turned off autosync (leaving mobile internet on) drainage went back to normal.
I still don´t know what caused this since I only had the google account, weather and dropbox installed.
Anyway, after doing a fresh install, the problems seem to have gone.
Of course I can´t be completely certain of it until some more days of testing/usage.

I also noticed quite a few problems since the latest OTA update.
Not only does the battery drain fast, the phone also feels extremely hot when browsing on 3G.
The phone does cool down pretty quickly when turning off 3G but it feels like I burned my hands
Here are a few screenshots.

I also experienced weird things when connected to EDGE (2.75G).
3G (HSPA) coverage on BASE (KPN) sucks in Belgium
Look at the video below for more details.
Has anyone else experienced this yet?
http://youtu.be/3g8FLpWDAYM
I also contacted HTC about this issue and they recommended a hard reset.
Unfortunately this doesn't help at all, I still get these weird glitches

mattionline, can you get a logcat when the phone's doing this weird stuff? It looks like the Home button is being pressed repeatedly and if logcat confirms it then it's probably a hardware problem.

Do you need root to make a logcat ? My phone is not rooted and I'm not planning to do it. How can this be a hardware problem ? I never had this problem before. I'm sure that it's a software bug.

I just fixed someone else phone that had the exact same symptoms. In the end I narrowed down the problem to one of his weather apps.
He had a live wallpaper that reflected the current weather, weather on his lock screen and a beautiful widgets weather thing. I never did figure out exactly which one it was I just turned off all there and told him he was crazy.
I don't know if it's something "weather" related for you but it maybe it will help.

you don't need root, just enable usb debugging in development options and connect the phone to your pc. You need to have the android sdk installed.

Sup guys , some of you don't seem to realize that there are many reasons why your battery drains, what you might think is, "quickly". A few tips to keep minimal battery out put...1 keep brightness down, the screen itself sucks juice probably the most. 2 check your apps, some apps send and receive data and/or are kept running in the background. You might have to enable/disable setting on shove apps. 3 widgets, widgets like battery meters, CPU meters, things like this constantly refresh to keep real time info. That also eats up alot of juice . 4 Turn off WiFi or any other thing like that when your not using it. WiFi continually sucks nice. Lastly, invest in some app that will help you close apps. Basically, tweek everything you might think that the os can run without. The less your CPU has to do, the more juce you save.

This made me lol hard.
Best advice ever.
But yeah, on the 1.0 version of Leedroid I had quite some drain, too.
When I turned off autosync it went back to normale. I only had my google account, dropbox (with syncing off) and the weather thingy set up and never figured out which one was resposible.
After installing Lee´s 2.0 ROM everything is fine.
I suppose there really is something wrong with the autosync and maybe with the weather stuff in particular.

My problem didn't go away with stopping auto sync, even without it, I had a constant data flow
Anyway, I rebooted the phone twice and the issue was gone.
It happened again a few days later, after the phone did shut down because of low battery. I put it on charger and turned it on, then, I noticed the 3G arrows were always on. After I unplugged it from the charger the battery went down in 10 hours. After a reboot, problem gone...
Since then, nothing...

And please note than when the problem is here, it's media and android os using a lot of data

I have been having one S problems too - I am on my second phone after the first one became reliably unresponsive every time I turned on mobile data. More relevant to this discussion, my battery died shockingly last night. Normally it drains at a few percent an hour when I am not using it (i.e. when asleep!) but I woke this morning to find it totally dead - that is 30% plus gone in 5 hours without it being in use.

Battery Life Decreased After Updating to 5.1.1

Before anyone asks I have searched, Googled, looked on reddit, and gone through these guides on xda:
http://forum.xda-developers.com/galaxy-s6/general/guide-to-battery-life-t3092593
http://forum.xda-developers.com/galaxy-s6/general/guide-battery-performance-tips-t3072049

I have a Galaxy S6 fro Rogers in Canada (no root) and I recently updated from 5.0.2 to 5.1.1 and my battery life has gone to crap, my usage patterns and apps remain the same as before. Previously I would get about 4 hours SoT, 5 on a good day. Now I can barely get 2.5 hours SoT. I have no other problems with this phone, none of the RAM issues, lagging, or over heating other people have mentioned, my only problem is the poor battery life.
The apps are primarily use are Facebook, Puzzle and Dragons, Messenger, and Chrome, I realise that these are battery guzzlers but 2.5 hours is ridiculous and I used to get more using the same apps. I typically start using my phone around 8am from 100%, and by 5pm after 2.5 hours SoT it is around 20% battery life, previously it would hit 20% around 11pm with about 4 hours SoT. No apps are draining a particularly large amount according to GSAM.
To reiterate the things I have done to improve my battery life are:
1. disabling unused apps in application manager
2. setting brightness to lowest setting on auto
3. restarting phone
4. restarting phone in safemode
5. clearing cache
6. performing a factory reset after updating to 5.1.1
7. leaving wifi gps off when not in use (but I'm not constantly turning it on and off either)
8. Greenifying apps I use less than once a day (but anything with push notifications is not Greenified)
Additionally I have not moved or anything and reception in my area has always been decent. Any suggestions for what else I should do? My phone is still under warranty, should I send it to a service centre? Or should I try rooting it an actually deleting bloatware and having an ad blocker (though this would void the warranty...).
Please advise! I am very frustrated with this battery life.

Im having the same issue after updating the GS6 on Wind (Canada) to 5.1.1. Terrible battery life and Android OS draining battery as well. I barely get 2.5 SoT.

I'll join this unfortunate crew. I have to charge everyday before leaving work in order to get through the day.
Take off the charger at home when I leave and by the time I get to work(30-40 min drive) I'm at ~95%. By lunch I'm down to around 50%.
Hoping Android M fixes some issues

Clear cache in storage option and reboot! It will very slightly improve!

http://communityforums.rogers.com/t5/forums/forumtopicpage/board-id/Android/thread-id/31962/page/32 Read through the last 6 or 8 pages over there. A lot of unhappy people with Rogers right now using the S6. I'm in the same boat. Crappy cell service, times it will show bars of 4G but then tell me there is no network connection. Try to make a call with full bars at 4G and it will say not registered on network. Text messages being sent and received twice automatically. No connection at all in places my HTC used to have 4G if not LTE. I had to send my S6 away for camera repair for a week so I pulled back out my old HTC M8 for that time and my connection was stable and awesome everywhere just like I thought it should be. Now that I'm back on my S6 it's barely hanging onto EDGE in places I had full 4G bars on the HTC like at my desk at work. Places I spend a lot of time at.
I suggest you call Rogers and talk to the tech support. Tell them your issues. The more complaints the faster the issue will be resolved. It sounds wide spread so don't waste your time trying to fix it yourself.

Thanks for the link, I didn't think to check the Rogers forums, I'll call their tech support to let them know of my issues and hope they are working on something.

I also have this issue. I was able to make it through an 8hr work day before the update. Now it's down to 10% or to completely dead. My usage at work did not change. Sucks that I have to plug my phone into my car just to get enough juice to make the drive home.

Just to confirm are you guys all now on 5.1.1 and is battery life the only issue you are experiencing?
I talked to a rep with my carrier (Rogers) and he said that the known issues were to do with connectivity (calls, data), but not with battery. He said battery issues that could not be resolved by a reset should sent in for service.

There was some discussion in various places about cell standby being a HUGE drain on the battery when connected to WIFI.
My issues are data and call related. I've never been one to care that much about battery but it does seem off from what I'm used too and I'm seeing some long times on the mobile radio being active.
I think it's safe to say that all of this stems for the 5.1.1 update. Cell reception "problems" can lead to big battery drains and if our phones are having issues staying in tune with the towers, it could cause big battery drain.
Keep an eye on what might be causing your battery drain though. It might be something silly like an app trying to do something.

I have also noticed a sharp drop in battery life now that I'm on 5.1.1.
USA AT&T.
I'm really at a loss. GSAM says "Android System" under apps as well as "Phone Radio" are the highest drain.

Battery Life Discussion after Marshmallow Update - Doze not working?

How is everyone's battery life after the MM update? Improved, same or worse?
Also, Doze is not working at all for me. I left my phone unplugged over night for 6 hours and lost 30-35% of my battery. That is far worse than it was on Lollipop. I did a factory reset after the update too, as I always do. WiFi scanning is off. I noticed my Android OS usage was really high when I woke up too. See attached image.

No problems for me.

Mine is really good. When idle, I'm only losing about 25 mAh.. I'm also using Greenify non root method.
Sent from my SM-G920V using XDA-Developers mobile app

Mines $hit! Even worse than before. I did a factory reset after update to mm. 5% drain per ~10min

Lost ~2% overnight.

Yeah. I lost 5% since 7AM this morning. That was almost 5 hours ago.

I just posted this on another thread. This may help.
1) Under Wi-Fi advanced settings, change sleep policy to "Charge Only"
2) Go to Locations -> Improve Accuracy. Make sure Wi-Fi scanning is off. This setting was moved here under MM
3) Charge the phone to 100%, let it run to 0. DO NOT CHARGE IT! It must power itself off. Charge it back up.
This had a dramatic result on my battery.

Please stop spreading false information.

1: Apps/sync will use mobile data as priority if this is done while waiting to connect to wifi. In turn, using even more battery if an app/sync wakes the phone switching between networks.
2: This is damaging to Li batteries. To extend the life of your battery, it is better to keep it topped above 80% and cool(not very common in real world applications). These aren't Ni batteries, long gone are the days of "memory discharging".
If you don't need notifications at night, use airplane mode. I miss Xposed, Autotasker, and Amplify(formerly Bounce)... Greenify is a good alt atm
Note: Sometimes even Play service updates will introduce bugs and or "retarded" policies that will destroy the battery, especially the "Now" systems. It can happen at the most random times as well and not at all most. Every now and then the fat man will get stuck in the tube.

False information? Kind of an ass thing to say, but suit yourself. Just telling folks what I did to FIX this issue as well as what has been posted on many other sites.
Some people find it easier to criticize those that try to help than offering solutions of their own.

I'm getting confused. Can someone please tell me what each of the three settings below from the S6 on Marshmallow actually does in terms of radio(s) used and sleep states? The wording of this setting is different in different builds of Android, and I'd like to know what each setting does specifically for the S6 on Marshmallow.
Always (Increases battery consumption)
While charging
Never (Increases data usage)
Here's the Android documentation if that helps.
WIFI_SLEEP_POLICY
The policy for deciding when Wi-Fi should go to sleep (which will in turn switch to using the mobile data as an Internet connection).
WIFI_SLEEP_POLICY_DEFAULT
Value for WIFI_SLEEP_POLICY to use the default Wi-Fi sleep policy, which is to sleep shortly after the turning off according to the STAY_ON_WHILE_PLUGGED_IN setting.
WIFI_SLEEP_POLICY_NEVER
Value for WIFI_SLEEP_POLICY to never go to sleep.
WIFI_SLEEP_POLICY_NEVER_WHILE_PLUGGED
Value for WIFI_SLEEP_POLICY to use the default policy when the device is on battery, and never go to sleep when the device is plugged in.

I'm not using any criticism nor is it an ass thing to say, just fact.The cellular radios uses more battery than wifi and even more when switching networks. A full discharge damages Li batteries. On a clean phone wifi always on WILL save some juice. At night, airplane mode will greatly reduce drain if you don't mind having no connection.
I'm happy it worked for you, however, bad information. Some simple research will tell you that. I see a 1 to 3 percent night drain on a clean phone with wifi always on, no scan, mobile data off. Hell, thats even with google pinging my old address from router on maps timeline.
@RylanM I know it says more consumption, but research and decide for yourself.

Marshmellow Upgrade | Awful Battery Life

Anyone else experiencing this? Atrocious battery life post upgrade. Nothing odd running in background, program or processes. Rebooted phone. Started the day at 100% with moderate usage at best, I'm already down to 19%.

Battery life is relatively unchanged in mine after the mm update. Easily make it through the entire day with 50-60% battery life remaining. I disabled a whole bunch of the bloatware (and will be removing it entirely when I decide to root my phone) and battery life is wonderful.

Mine has been fine, slightly better with doze/disabling packages. Do a back up through Smart Switch and try a factory reset. I do that every time I update.

I'm envious of your successes. I'll give it a bit to see if it stabilizes, if not I'll use SS and reset/restore.

I will recommend "Package Disabler Pro" to disable bloatware. Costs but is worth the cash.

Mine went through on Thursday and so far battery appears ok.
I have noticed however the lighting is messed up all over. Play books night light feature is broken and dims it to unrecognizable levels. I have to go into the settings again when in the book and disable auto lighting and manually raise it. When back at the list of books screen, the brightness drops to nearly off again.
Also it seems the notifications when listening to music are much louder. I could listen to mp3s via poweramp while reading a book and get an SMS text and itd be a light little sound. this is playing louder than my music and very annoying.

My batter life was horrible after the upgrade. Here's what I did to fix it.
1) Wifi sleep policy - Changed that to "While Charging" (big difference noticed after that)
2) Fully charged phone then let it run down to 0 (must let it power itself off)
3) Wifi Scanning has been moved under Location setting. Go to Location -> Improve accuracy, make sure Wi-Fi scanning is off.
Batter life is awesome now.

All thoughtful replies. I don't have Location on ever, unless I'm using Waze, so that's a non-issue for me. Allowing WiFi to sleep when the phone is off, while I'm only connecting via WiFi, effectively makes my smartphone a dumb phone, until I wake it up, right? The fact that I need to start changing around "normal" settings on my phone, to lesser benefiting ones, to get back to the battery life I had before I installed MM is pretty silly. I've been hoping things would settle down, but they don't. I can try using SmartSwitch later to see if that helps.

No, it will connect LTE and then switch to wifi. LTE use more battery life, the network switch uses a bit, then finally you are into wifi. If your phone wakelocks or alarms(location ping, play service ping, etc) it will use more battery than wifi always on. Personally, I've tested both to make sure a wifi wakelock bug hasn't been introduced as I do with every update and play service update(it does happen and it's horrible drain). I see more savings always on.
If you meant you disable mobile network, yes, dumb phone, text and call. Also, I disable mobile usually always as I piggyback off work cell at work, and always wifi at home. I only toggle mobile data when necessary.

I believe this is what most people encounter. Most dont have unlimited data and use WIFI always. I think by default, WIFI is set to always on, even when phone screen is off. WIFI will rape your battery. I did my own tests with wifi vs 4g and just by using my 4g all the time, battery quadrupled. Many argued that WIFI uses less battery, and i have the best of the best wifi router/modem/isp with 5ghz ac excellent coverage. Not the case for me. I have unlimited and just stick with that now. Battery life on MM has been great for me.

My battery life is 4x better. I couldn't be happier.

Anyone else experiencing this? Atrocious battery life post upgrade. Nothing odd running in background, program or processes. Rebooted phone. Started the day at 100% with moderate usage at best, I'm already down to 19%.

Mine is exactly 4 times worse

Battery the same.

Going to factory reset and start clean, been a while.

Has Verizon released any new updates to patch the issues with Marsh Mellow update

Not that I know of.
Though they JUST released Marshmallow. Verizon is probably still patting themselves on the back even though they released several months late. What I'm waiting for is a miraculous root.

I never use my phone the same amount every day, so it's hard to say exactly what kind of battery life I get, but I have noticed that it has improved. I would usually be near 15% by 10pm after coming off charger at 6am. Now I float around 25% at 10pm. So it seems to be better, even if only slightly so.

I see a minimal improvement, but I was doing what I could without root prior to sleep unnecessary crap.

Weird, when thye MM updated happened, up until the last two days, I was getting much better battery life under MM. But the past few days my battery life has declined dramatically to the point that I am not getting through a day of minimal use. Screen only 2%, Android OS consuming 76%.
I just fiddled with settings (Changed Wifi sleep to While Charging; Turned off wifi scanning). I am going to also try a reboot to see if that helps. I swear it started just about the time I started looking at Nexus 6p replacements).
Update, rebooting, and removing a few more useless apps and battery life has returned.

Really bad battery life

Hello all,
I just bought a new galaxy s7 silver (exynos variant) around 3 days ago and my battery life seems to be really bad. I've only managed to achieve 1h 56m screen on time and I'm already at 41%! I keep auto brightness on and leave always on display off and don't keep things like mobile data active. If anyone can suggest how to fix this it would be phenomenal .
I was quite sad considering I have heard of people who can achieve 5+ hours screen on time with regular usage and not having to compromise on switching everything off .
Thanks for the help in advance

Do you have Google Chrome installed? And can you see something like "media server" in you battery usage log as a high power consumer?

I would send you a picture of my battery statistics but for some reason every time I try to upload a picture I get "network error"
My top consumers are :
Screen 31%
Android system 19%
Android OS 9%
Cell standby 7%
Mediaserver 4%
And Also I do have Google Chrome installed

Good day.
Try this and see if it works:
-In settings -> privacy and safety -> location -> improve accuracy - Turn off wifi scanning (The phone turns on and off wifi regularly for location purposes and it uses some battery)
-In settings -> Display - Turn off smart stay
-In settings -> Advanced features - Turn off pop-up view gesture, Smart capture, palm swype to capture, smart alert and easy mute.
-In settings -> Accounts - Turn off auto sync
Turn off hardware step counter at S-health app.
Use Greenify to hibernate samsung and google play app and services.
And if you want to stretch it more have a look at this (http://forum.xda-developers.com/galaxy-s7/how-to/touchwiz-bloatware-save-to-remove-list-t3330241)
Hope it works for you.

Hi mate,
The 2nd guy in this post touched on it. When you see Mediaserver on your battery stats it's normally a sign that your phone, since being on, has got quite hot and there has been substantial battery drain. I've had this same issue before too. Factory resetting etc wouldn't help. And the phone would get so hot. Eventually I read and found a link between Google chrome and Mediaserver. I deleted chrome and mysteriously the issue left, that was on my last s7. My current s7 I got yesterday and haven't got this issue once, despite using chrome right now.

Yeah I did notice that the phone was heating up rapidly and my battery life was falling heavily. I will delete it and give an update to see if it works.
Thank you

Right I tried it and at first I thought that it worked but then today I am down to 25% with only 2h 5mns screen on time. Anyone got any other ideas?

Sorry read that wrong lol I read 25% battery for 2 hrs screen on time!
Accounts syncing in the background could be a culprit or some of the fancy software functionality that Samsung cook in to touchwiz. I generally don't have anything working or syncing that I don't use.
Might be worth going through all of your settings one by one. That's what I did when I first got the phone.

I'll give it a shot , how does your battery life seems to do? also, do you use power saving mode ?

At this moment in time I've had 2 hours 44 minutes of screen on time and I've got 53% battery left.
The majority of that usage has been on WiFi though and I do have auto brightness enabled. One thing I have noticed about the s7 screen is, it is very good quality and incredibly bright. I have spent a good amount of time tweaking the auto brightness so the screen isn't any brighter than it needs to be in various light conditions.
I was suffering from rapid battery draining and the phone getting overly warm when I had Google Chrome installed. I've removed it, and it has taken those issues away completely.
I have come from a nexus 6p and don't miss the extra 500mAh of battery to be honest.

3hr 28 minutes of screen on time now with 43% battery left. Still on WiFi but have been playing a bit of order and chaos 2, reading the news, browsing forums and general Internet surfing. I don't have much on in terms of push notifications other than Gmail and have my Samsung Internet app syncing and some stuff related to my Google account.
If it's of any help at all, my phone is on the 3 network in the UK running the stock 3 branded firmware.

Yes my battery life does seem to have improved considerably. I am at 50% charge with 3h 35mns screen on time so so far so good

Good news mate!

Alright all was going well regarding batteey life until recently when it began to slack off again. I hopped in to srttings see what was consuming all of my battery life and it said android system. Anyone know what that's all about?
