Fast discharging

I896, Rooted, factory Gingerbread.
I have a Captivate and a Tab. Both Wifi only, no Sims, Airplane mode on, Bluetooth off. Machines are on but screen is off. The Tab looses 3% over the course of the morning and the Captivate looses 20%!
I'm running regular 'power user' type apps; Titanium Backup, Tasker, LauncherPro. If there are any apps notorious for secret batt consumption, let me know what to avoid.
Running SystemPanel Lite - I can't see any app that is taking up more CPU time than normal that would explain this kind of drain. The battery page shows a good proportion of battery use display and wifi. In one instance I used the Captivate so little that display showed less use than wifi. In the course of just checking phone power consumption, the display use percent way up, just like expected (Just to show that wifi was really doing almost nothing) and still I had lost more than 15% of battery over the time when the phone was supposedly idle, not connected to anything with the screen off. Some ghost is sucking the life out of my battery. Grrrr. What could it be?
I loose 30% in a night with wifi off, backlight set to absolute min and nothing runninng or syncing.
I don't get it. Any ideas? What do I try next?

His tab is running Android too.
If you don't have anything helpful (or knowledgeable) to say don't say anything.
Op, download watchdog from the market, (system panel is kinda ..meh.) and see if there us a rogue app munching battery.
You may consider flashing a ROM see if its just that firmware/kernel reacting to your phone.

Have you tried Juice Defender?
Also, check to make sure you don't have applications constantly running. What version of android are you running? Check in system settings -> status -> somewhere in here you can check the battery status and what applications are pulling the most juice ... From there if one application needs to be removed you can action it ...

Also try the "Battery Calibration" app in the market. It's free.

my captivate running cm7 STOCK will drain down to 20% from being idle for 12 hours
my battery will also drain 30% from 45 mins of wifi only use.
doesnt help him but thats my experience from my captivate

Menu -> Settings -> Wireless and Networking -> Wi-Fi settinngs -> Menu -> Advanced -> Wi-Fi sleep policy
Set it to when screen turns off.
We have to switch that every time we flash. I really wish it was default. Some ROMs also have background data control, but it's usually when wi-fi is on so it shouldn't be a problem.

You do know that cm7 doesn't have the proper hardware drivers from Samsung so the battery life is known to be HORRIBLE right? If not you should really read up on the ROM you're using
Flash any touchwiz ROM, especially a native I897 build and you will see a dramatic increase in battery life.

I'm on CM7 and am going on 27 hours with moderate usage.. Granted, I have the 1800 mah battery from the Sprint Galaxy S2

trying flashing to pinnacle. I too have battled weird captivate drain issues.
if you wanna try CM, read my thread:
http://forum.xda-developers.com/showthread.php?t=1364357

I've held off replying as I was trying a few things and figured I would report only once I was done.
I found and ran Battery Calibration, just before I read the post. Between that and turning Wifi sleep policy to off with screen off, I had a great weekend. I was getting a day and a half out of my phone, which considering the use, was very acceptable. I was getting about the same drain as my Tab. I had 1% battery drain after 4 hrs of screen off time. That seemed fine for me.
I got back to school where I teach and yesterday the phone drained as fast as it has before. Interestingly, it continued its rapid drain even after I left the school and went back home. So, it died at 4am this morning. I heard it shut down. The school has at least 4 routers, two of which have 5k access options. I know if I choose them, my laptop drains way faster. Is there a way to limit my wifi connection on the captivate and not use the faster 5k connection?
But, this still doesn't explain why, even after I leave the school, the Captivate continues to drain when it is 10ft from a single 100mb wifi router.
I'm almost ready to try a custom Rom, but not sure how that will affect my ability to use it as a phone, once I get my Sim activated. Still new to this all.

You think everyone running a custom ROM doesn't use the phone?
Shouldn't affect your ability to do anything...

The WiFi and cell radio do increase power on lower signal as we know, but that's not always the cause of drain. I remember times using Froyo when kswapd goes nuts for no reason, or trillian, email, twitter or some other app just starts using massive CPU. Many apps are probably never tested on a system that has no connection most of the time. That's where all the utilities come in handy to find the culpret. OSMonitor can help find CPU hogs. TiBu can freeze apps, or uninstall them temporarily. Juice Plotter can monitor drain over time (newer Androids have something like it built-in). It takes some time to find it, but newer versions of the OS make it easier and have less trouble.
Also the battery % is only estimated. I'd trust full to empty time rather than 90% to 80% time as 10% use since it's not really as linear as we think.

Not to point out the obvious, but it can be the battery itself that has the problem. They aren't exactly manufactured to NASA standards... well, maybe their standards lately, but the point is, sometimes the ghost you're chasing is staring you right in the face.

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.

[Q] Verizon SIII battery drain on standby, help identifying root cause

Hello,
I'm a first time poster looking for a little help. I've had my Verizon SIII for about a week now and almost everything about the phone I have loved with the exception of the battery life. Given the 2100mah battery I was expecting much more. I tend to be a fairly light user throughout the day at work, I have the screen brightness turned down, all data is off, and I really only am using it for texting, maybe a little bit of gaming. I have found that if I unplug at about 8am by about 6 or 7pm the battery will be nearly completely drained.
Noticing that this seemed to be a fairly common problem I started doing some research to determine the source of this. First, by looking at the battery stats I observed the same problem that many others observe, a heavy drain in standby mode.
ttp://i.imgur.com/2drJy.png (since I'm a first time poster I can't add external links, please just add an H to the beginning of the url)
So going off of this I started trying to determine the cause of this drain in standby mode. I should also mention that at times the phone does seem to get warm in the bottom left region of the back of the phone. I had read one tutorial explaining about wakelocks so I decided to check that out. I downloaded GSam Battery and CPU Spy to see if something was preventing my phone from entering standby mode properly. However my phone was entering deep sleep as shown below, so this confused me a bit. But clearly there is some issue visible in the standby mode of my phone, sometimes the battery will drain ridiculously fast (as high as 1% every 5 - 10 minutes). And keep in mind that this is while virtually everything, data included, is disabled. So that eliminates the possibility of it simply having to search for a signal in a weak area.
ttp://i.imgur.com/pekXb.png
ttp://i.imgur.com/xauHF.png
ttp://i.imgur.com/2drJy.png
Basically I'm having a tough time getting to the root cause of this problem. I feel like there's some little software issue in there that is draining it. But I've been pretty smart about the apps that I've downloaded, I've stuck with only very common and popular ones. So would anybody have any clue to how I could identify and address the source of my battery drain?
Thanks

You don't have to thank me there is a button for that

Download and try Watchdog Lite. It's a really good monitor for finding out which apps are acting up.

This doesn't exactly answer your question, but can help with your problem. There are programs that can help to drastically improve battery life by turning off data (3g\4g) while the screen is off. This can double your battery life or more, especially for lite/moderate users. Most of these programs work by turning on the data 1 minute out of every 15 the screen is off. That way you still get email, and notifications. You still get txt and phone real time, as they do not rely on data. When you turn the screen on data is turned on, when you actually would want to use it. Especially in 4g areas this really saves battery, as 4g is a battery hog.
Battery Defender is my favorite. I feel like I should be paid for this advertisement...

Do you have BATTERY SAVER option ENABLED in settings? That makes a huge difference for me.

It sounds like you are still stock, but I used the Root66 image and after that started having huge battery drain. I did a factory reset to no avail, so then moved to Synergy Rom. Since then, I've had outstanding battery life! not sure if you were thinking about going this route, but it has worked for me. Synergy is debloated so I assumed Verizon crap to be the culprit.

The images I saw were all at 100% battery. Those are not very helpful. A shot of your battery stats at the end of the day would be a lot more useful.
Please note that Cell Standby reports incorrectly at the moment on the S3. Unless you do the fix linked above, it will nearly always be at the top, but it does not actually drain that much battery, it is simply a reporting issue.

Nexus 5 battery drain - new battery, new ROM, still persists

My beloved red Nexus 5 starts acting up... the battery drains extremely fast. Some weeks ago, I could barely make it to 2pm without having to recharge after unplugging. So I got a new battery (directly from LG, so definitely a genuine part) which improved the situation, but didn't completely solve the problem. Additionally, I flashed a CM 13 CAF ROM (using myfluxi's kernel) onto the N5 - I enjoy it so far, but there was actually no further change converning battery life.
Right now, the phone is at 10% after being unplugged in the morning at 9am. Wifi, bluetooth, GPS and mobile data were constantly on, cell signal was mostly perfect, wifi was connected for about 3h, bluetooth was always connected to my Moto 360. Screen on-time is about 2h and I listened to music using GPM for about 2h. The battery settings do not indicate any app using up too much battery power - it shows the display at 15%, cell standby at 10% and then several apps.
What do you think - a Nexus 5 with a new battery should make it through a day, shouldn't it?
I remember my first Nexus 5, back in the days with a G watch, making it through a day without any problem with 15-20% left when I plugged it in before going to bed... because of that, I start to think if there might be a bad electronics part, like the display backlight or something on the mainboard, using up too much power without being noticed by the OS. Is that possible?
Thank you very much for your advice!

Read and post in the battery life troubleshooting thread stickied to the top of this forum, it will help logically determine what is using your battery.
You have a lot running at once, so difficult at the moment to solve your issue. It's better to turn things on/off one by one to make logical conclusions whether it has any noticeable effect.
The best logical way to conclude if it is a hardware problem is to go fully sock no additional apps no root etc, see if it 'drains' by itself
If not hardware, then 99% of the time it is a bad app(s) keeping your phone awake

This is likely not the case, but have you checked the CPU settings? I've only encountered such a drain while using performance governor together with overclocking.

Same here
I have the same problem and I have been banging my head about it, I don't really use my phone for anything much else than a phone and I kept having at least 3 days of using it with no problems.
Now the phone barely lasts 2 days and even switches off in the middle of the night...

In the OP's case, his drain is likely caused by having GPS on all the time. That will absolutely devour battery life, so he could save himself some grief by turning it off until he than your phone turns off occasionally. First guess would be the power button going bad; that is generally the reason for needs it.
For you, who knows? You've not given any information, otherthat type of behavior

Yes, sorry about that I was a bit annoyed at the phone. I found and fixed the problem. Go to settings > apps > disable google fit > click yes when it gives you some notifications about how you'll lose data or stuff like that > and click force stop at the end for good measure.
I am in my second day now of battery life at 59% with a looooooooot of talking today , I mean more than usual so it is definitely a fix for me. Hope it helps

Again same problem
Hi all,
Unfortunately I have better battery life but I am again losing a lot of battery.
I have a screenshot but I am unable to upload it sorry about that.
I use my phone mainly for calls roughly about 15 mins per day at the most in total ( not a lot at all I know) and I also have my bluetooth on at all times cause I have LG G Watch.
thing is that I have never had problems with the battery before. When I say before back in the day I still had my LG G Watch ( I have it for about 6-7 months) . Problem with the battery started roughly around 1 month.
Location is off, wi-fi is on on very rare occasions throughout the day when I need to check my e-mail and mobile data is the same. Navigation is used only if needed.
The real problem is that before I knew what was draining my batter now I have 79% of battery usage and I have 5 apps listed that drained each 1%
Android System 1%
Phone Idle 1%
Screen 1%
Google play services 1%
Android OS 1%
Where are the other 15 % ??
It is weird I really took pride in that phone and his battery life, I know that it is mainly because I don't use it as a regular used do i.e. gaming, facebook etc, but I still want to charge less than 1 time per 2 days or less
Thanks in advance

Nik

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.

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.

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.

Been on MM for about five days now and my battery blows, so much worse than what it was!

Mine is exactly 4 times worse

Battery the same.
But I have to tap the screen harder to chose app.
Going to factory reset and start clean, been a while.

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.
