I've been noticing a weird shift in percentages of usage on my battery. Before a few days ago, display would take up a good 70+% of the battery. Now, I seem to be seeing a 40%-ish usage from Android System. My girlfriend and I have the same phone, we both unplugged at the same time and within 2 hours, hers only had about 4 minutes of CPU usage from Android System while mine had a whopping 1 hour.
I can't figure out what the problem is or what's causing this.. Anyone able to shed some light on this for me?
I noticed that Android System is using the second most battery after the display for me too. Hadn't noticed this at all until today. Are you rooted?

I am not.
It just doesn't make any sense to me because my girlfriend and I were in the same spot for those two hours; nothing should have been different.
Yeah that is weird. Anyone else that can shed some light on this?

Sounds like a rogue process. Reset and see what happens.
You may want to use an app like Quick System Info Pro (or something else, can anyone suggest one?) and capture logs of that process. That might shed some light on whats going on.
I had that problem, and then through elimination figured out that if I had a clockweather widget on the home screen, it caused some issues. I dunno why.
a number of things are always going to be using the battery. if the display isn't the biggest battery user and the android system is than it simply means that a number of background processes have been consuming your battery while your display has been off. how is or was your battery level compared to your girlfriend's phone? perhaps you have more things that are sync'ing in the background than your girlfriend. anyway, unless you're seeing an unusually high drain in your battery than I wouldn't worry about it.
Well, I powered off/on the phone and it doesn't seem to be doing it anymore. I would love to find an app that could help me pinpoint this next time so I don't have to power down my phone just to fix it. I have aLogcat installed but I can only see the past two minutes of logs because it goes by so fast.

Yeah, the problem is how much battery it was draining. Within the 2 hours it was unplugged, I lost 54%; she only lost 29%.
Ive had this same problem with Android System going crazy. I have no idea what causes it. A reboot fixes it, but it's pretty annoying.
Yup. I've seen this too.
I'm gonna guess you guys were on 4G? I've read this exact thing happening to a few people, and they've all been on 4G. It's happened to me three times -- all on 4G. I keep my phone on 3G at work because the signal is terrible and WiFi at home and haven't seen this issue in those circumstances. Some kind of 4G radio issue, most likely.
I read in another thread Verizon is aware of the problem (or so somebody was told on a support call about it), so hopefully it'll get fixed in an OTA update.
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.
Anyone experiencing excessive battery drain for the paid version of Lightflow? I love this app, but after checking betterbatterystats, i realize that it forces my device to be awake all the time thus drains the battery faster.
I am using the Canadian Rogers RAZR HD rooted but on stock OS.
Now that you mention it, I too wonder if light flow is responsible for excessive battery drain on my RAZR Maxx HD. Before I installed it I was getting over 36 whores of use. Now I am only getting about 14. It isn't accounted for in battery stats so I am going to uninstall top see if it lakes a difference.

What sort of drain are you looking at? The app will cause a lot of wake locks that'll show in better battery status, but it's fairly normal for the app. The reason for this, is that every time the notification changes color, some code has to run to change it. To run in the phone needs to be in a partial wake state. If you find the phone showing as awake in the standard android battery graph then something doesn't sound right. Let me know and I'll try identify any issues or suggest changes in settings.
Seems OK to me, most of my wake locks are just exchange or stock ROM stuff.

No problem at all for me with light flow.
Any news about LED while screen is on?
yeah it does drain excessive battery
i do confirm that since i installed light flow the phone just drains the battery , i got 9 hours of normal use instead of 20+ of average use .
good thing that you brought this up and confirmed my theory . i have RAZR MAXX HD ad proud of it

In the standard battery graph, it does show lightflow as being awake for almost the entire time the phone is on (even during screen off). My device almost never sleeps. I can grab screenshots of any screens you request if this helps.
This is why I love the app, the developer cares enough to try and make a difference. I am definitely hoping I can fix this because the functionality of this app is fantastic!

It's always an odd one to try and track down, but there are a few things to try.
If at all possible is it possible to see if there's a particular notification type that it starts happening after (ie get a notification, view/clear it and see when it's not sleeping). It may happen for all notifications or it may just be a particular type - any info on this is certainly useful.
Then when you have no outstanding notifications and are getting the phone to be awake all the time go into lightflow->tools->logging and select "file logging". Then press your phones "home" key.
Leave your phone idle with the screen off to approx 10 minutes. Confirm that the phone stayed in an awake state. If it did then go into lightflow->tools->logging and select "no logging". Then go into the contact us section and e-mail me. The log will automatically get attached.
Info such as custom roms, non stock apps (such a handcent) that you've used can also be useful, so drop a note in the e-mail about the tests you've done. Hopefully there's something I can then track down.
Hello, two days ago I closed the lid of the cover and put my Note Pro LTE in a bag. I just took out the device and found that there are about 81% left. Is this normal?
Depends on what you're running in the background.
Mine looses about 1% every 24h when in deep sleep. I've got everything turned off, including sync, gps, wifi, mobile data (I'm not using a SIM yet), most of the bloatware including touchwiz.
So, even I closed the cover, apps were still running and the power hunger ones continued to consume power?
Just check the battery stats...

Power hungry, no; but background processes still run like email checking and other sync services.
Considering you probably have sync set up for an email account and Google play services is likely running as well getting about 0.5% drain per hour seems reasonable to me.

Turning the screen off doesn't disable Sync. With Sync enabled, it keeps actively checking for new emails and the lot. Think of it like going to sleep, and waking up every 5 minutes to check your mailbox.
It temporarily pauses games and videos, but it doesn't quit the app. You have to do that through the recent apps menu.
Is there an app that also put those sleepless apps such as sync to sleep when the lid is closed?
When it comes to battery life the first thing to do is get a handle on what your current drain is.
Monitor your battery stats page, look at the times that the device wakes up and at the rankings of applications to see what's using the most power. Third party applications can help here like Better Battery Stats or GSam Battery Monitor.
From a fresh clean boot with a full battery let the tablet sleep unplugged while on WiFi without ever opening any applications or turning on the display. Let it sit like this for at least a few hours and determine your average hourly % drain. Use this as your baseline and see what applications rank near the top. Repeat this with WiFi turned off and the tablet on LTE. Compare the two and if you see higher drain on LTE take a look at your signal strength. Most likely if LTE signal is weak then drain will increase as the radio tries to compensate.
If you see more than a percentage point of drain in deep sleep while on WiFi then chances are an application is keeping the tablet awake or waking it frequently. Those applications will likely rise to the top in the default battery stats page. If not, the third party applications can assist you in figuring out what's wake-locking the device.
Thanks, I will try the test under wifi. I haven't used LTE yet. I bought the LTE version because it has faster processors and quick charging.
Do the tips mentioned in the article also apply to our Note PRO? Do Airport Mode turns off those apps we talk about?
http://www.phonearena.com/news/How-...one-or-tablet-quickly-and-efficiently_id56242
Since 4.3 Samsung OS has a process called Index (from indexing files) draining a lot of battery juice from its first start till completed process (just for 2 days i think).
I had noticed this since Note 2 update to 4.3, and now with 12.2.
But I can be wrong......or not.

Seems fairly logical when you think about it . . if you're trying to fill a bath tub it will fill much faster if you close the drain at the bottom . .
I took my Shield Tablet (stock 5.0/rooted) off the charger at around 8 am today starting at 100% (charged while completely off), and at 11am I noticed it was at 49%. I'd only done some mild gaming (Terra Battle), and Comixology reading, so it struck me as a little low, but what confused me more was the battery stats page. Screen shows at 130%, System at 10% and everything else in single digits.
Anyone know what's going on here and how to fix it? I've rebooted and will be watching out for whether it happens again, but would be happy about feedback from anyone who's experienced a similar issue. Thanks in Advance!
Since you are rooted you should use an app like Better Battery Stats to log what is going on.
This way you can identify which app is causing the drain and take measures to prevent it.
Known cause in quite some cases is Facebook after applying the ota to 5.0.
Solution is to remove the facebook app, do a factory reset and install the app fresh from playstore.
Thanks for the reply. I don't and never had the Facebook app installed (shocking, I know ) so that can't be the issue.
I've installed Better Battery Stats so I'll see if I can figure anything out through it...
My guess is that the screen has used 130% of the batteries capacity. If you look at the bottom of the graph it says stats since last full charge. I gave my niece my old first gen nexus 7 with lollipop and a few days later looked at the battery stats. Her screen was listed as 160%. It hadn't been fully charged since I gave it to her. The screen brightness was maxed out and she tends to leave it on the ground with a video playing. The screen obviously uses a lot of power so its not hard to imagine it was over 1.5 times the batteries capacity.
