battery drains.. sort of

Does anybody know sone work around regarding this? Because its starting to annoy me, have you ever experienced when you are using your device,the battery warning suddenly pops up and says that you must charge already and the battery percentage suddenly changes to 3% eventhough awhile ago there is still 50% left, but when you reboot it chages back to 50%, what could be a possible culprit, this happens a few times to me a day and im tired of rebooting everytimethe warning pos up.
Any advice is appreaciated

Same experience. I posted this a while ago but no solution.

well this isnt an acutal solution but have you tried actually draining your battery down to 3% recently? By doing that you are "calibrating" the battery life sensor and maybe that will cause this issue to occur less frequently?
This happened to me once so I did that and havent had a problem since. Hopefully it works for you!

but how do you power it on if thinks the battery is critical

Somehow if ido a reboot it just goes back to normal..maybesomething is messing up with the battery sensors,i did let it drain but some how it still the same, i had read on a similar thread about a bump charge or something maybe i could try that and lets see from there

on verizon tab SCH-I800 - does the same thing ... mine seems to happen around 33% though. (i thought it was something with the 33% .. since it would drop down to 3%) ..
i think samsung should really push out an update to address some of the glitches in these tabs..

Tried the recalibration thing. Problem still exists.

thats a similar issue i get,. Yes i tried the recalibration charge also and still having the problem, i did a factory reset also and it did nothing.. Im really desperate for some fixes..

Mine jumps from 15% to 3%. Quite annoying, I assumed that it is because it is poorly calibrated and so it doesn't realise its actually critical until its 15%.
I tried calibrating it by running it until it switches off, and then fully charging. However, that didn't work.
If in reality the battery is at 15%, then its a pretty bad software bug.

Maybe deleting the battery stats solves the problem?

I think its getting worse on mine now after a full charge after i remoce the charge around 2min. It says 3% again what the heck?

try to flash it with rotohammer rom JHA/JMC it might fix the issue. My problem with GT was battery draining too quickly but after flashing it's much better now.

This worked for me too, however I had to do it 2 or 3 times. I haven't had any problems since.

I think i sorted it out also by calibrating battery,i removed the battery stats using the root explorer,now im still observing the progress

Brand new sprint tab, only installed the over clock kernel first week i got the.
Today, which would be week 3, i experienced the 35% to 3% drop instantaneousness..... So, im draining the battery, and hopefully doing a full recharge...

I also have a sprint tab and it is three months old. I have not put another rom on it, only rooted it. It also has developed this battery problem recently. It will go from 53 to 3 all of the sudden.

Not too sure what's the issue but it does sound like a program consuming too much CPU or the battery calibration issue.

Anyone else having partial wakelocks/worse battery life after JB OTA?

Just wanted to throw this out there and see if anyone happens to be getting a lot of partial wakelocks without screen on or if your overall battery life has decreased since installing the 4.1.1 OTA. When I first purchased the phone, I had very very few incidents under my battery info where I would have a session awake without the screen on. Post update, seems like I've got a ton of really small wakes with no screen activity. I have turned off Google Now and every GPS/Location setting I could find. Downloaded Better Battery Stats today so I'm going to see if I can get some better info on what's going on, new to the program though and I don't understand most of the info that it reads.
Prior to the update, letting my phone sit overnight I would maybe see a 3 or 4% drop over the course of say six or seven hours. Now I'm seeing a 3 to 4% drop in battery per hour, more if I'm actively using the phone. I'm going to do more testing, specifically overnight to see how it fairs. Just wanted to throw this out there and see if anyone else is experiencing any of these issues.
:good: -Matt

I am noticing the same thing. Don't know the cause. Keep sync off all day.

Im getting the fast dormancy symptom again... no matter what i tried I cant fix it... always connecting as HSPDA+ even if im not using......anyone got any ideas?

Hmm, might try a factory reset and not installing any apps at all and seeing how it fairs. By chance, do you guys have any of the stock bloatware apps disabled? Not rooted/Frozen, but just disabled via the apps menu? Wondering if perhaps disabling any of them might be a trigger.

Yea i'm getting that. I'm using 13% overnight now vs like 4% before. Not sure about the wakelocks though.
Some random things I've noticed are the blur widget resets itself alot. And the transition to the settings window on the left is laggy. How would one revert back to ICS? Google Now is not that worth it to me and the phone was smooth enough before. I'd take the battery life over the new features.
I did buy a second Razr M for my girlfriend that's still on ICS. I guess I can do a side by side compare this weekend.

I am loving the update.. only issue so far is fire fox crashing..no battery issues. Must be settings guys..

i don't think it is setting i have all my syncs to manual, and i have been noticing a lot worse battery life since the update i would have 18+ hours or so off charger with pretty heavy texting / game / some voice calls. Now i'm not getting close to that. I just disabled the fast dormancy service to see if that helps any, ill post back results

Just did a factory reset today, I'm not going to disable any of the bloatware this time, and I only installed BetterBatteryStats as well as updated all the default apps in the Play Store. Going to see if I get any wakelocks this time around.
Last night, after a period of 6 hours, I had over an hours worth of partial wakelocks from AlarmManager (subheading Phone).
-Matt :good:

I disabled Google Now and my phone used 7% battery over 6 and a half hours. A little bit better.

A factory reset (annoying as it is) helped me considerably. My phone was also seriously laggy before the reset...slow like my old DX on GB, much worse than factory ICS. It finally feels smooth now, like JB should.
Still seeing a lot more wakelocks than on ICS, but it doesn't seem to be draining the battery like it was before the reset. I also removed or disabled a couple of apps that seemed to be serious offenders (Accuweather was one).

Did a reset on mine as well and did not restore from Google backup. Still seeing wakelocks, but as someone noted earlier they don't seem to be draining the battery too much. With that said, the battery does still seem to tick down much faster than on ICS. One thing I did find that helped, although honestly it's not really a solution, is turning off data use when I'm out and about just answering texts and such. If I have data/wifi disabled, I'm getting closer to the battery life that ICS was giving, but then again who wants to go around having to toggle data on and off every time you want to look something up.
-Matt

Is maps showing up on your battery stats and you're not using it? If so, simply open the application. It should say "updated to the latest version" or something like that. If this is happening, this will solve your battery problems.
Happened on my Galaxy Nexus and was happening initially for this phone too. Hope this helps someone.

Modem Fast Dormancy Monitor Service Not Responding.
Me and my wife both updated to KitKat on our Razr M's. I like it so far. The pop up about modem fast dormancy bothers both of use. When you look under battery, it uses more battery than other apps. I force stop it, reboot and it comes right back. A chat on Motorola web site sugested to wipe partition cache. The link that was provide gives the wrong instructions. KitKat using the power and volume keys has changed. They forgot to tell some people. That didn't work! I sent a long email to Motorola telling them that someone messed up or they did this for a reason! I guess if you get mad enough you'll just buy a newer phone. If that one thing is fixed, we would both be happy. The white background in text take some getting use to also. I hope Motorola will help us, but I kind of think Razr M's will be considered OLD! They are betting we will junk them for a new model.

n00b here, need help with battery issues

Hi there; this is my first post so please go easy on me.
Bought a Nexus 4 which is my first Android device, but the battery life is bugging the hell out of me. Surely the screen should always be at the top, right? I left it to sleep overnight on a full charge to find that it had shot down to 60% when I woke up at 7 this morning.
I haven't rooted or flashed or anything like that, because as I said, I'm an Android virgin. I have location settings off, only Gmail syncing and the usual push notifications here and there. Nothing too fancy or strenuous.
Any help on how I can go around fixing this? I'm a little afraid to rooting/flashing/ROMs etc, because I've no clue what works best.
Cheers!

If your saying you left the screen on over night, meaning the phone never went into deep sleep.. If you slept for let's say 6 hours and the phones screen was on for that whole time it's normal that it went down to sixty percent battery.
Maybe I'm understanding your post wrong? Btw I cannot see the picture you posted.

Turn off mobile data and lower the screen brightness to 0 during the day. Also disable WiFi when you're sleeping. I also make sure all apps are closed using the app manager button on the far right.
Mine's been fine following this logic.

Oh sorry, I should meant sleeping overnight, whilst I slept cosily in my bed.
I'll reattach the image in a second

This is NOT the answer. His battery in the image has dropped 7%. If he hasn't used the screen much it is perfectly understandable that screen might not be a large percentage of that 7%. As he uses the phone more screen will use a larger percentage of his battery and Android OS will use less.
If he gets to the point where the screen is on for an hour or two and the percentages are still like this then yes there is a problem.

Actually No the "Screen" should not always be at the top of the stat list. If you use the phone more than it idles, then yes... but if you are like me, mine says "Phone Idle: 20%" (which is on top) and "Screen" is 4th on the list with 12% (Wi-Fi and Cell standby above it) [this is my personal phone, and I mostly use my work phone. hence the high Idle & standby]
I was having an issue with my phone running out of battery, with very little usage from it. I mean very little, I might make 2 calls from it each day, and respond to an email now and then. I found that an App was preventing my Screen from going into "Deep Sleep" or even "Sleeping" possibly. So I uninstalled all apps (well I only had like 4 additional apps installed), except for 2 that I need (Google Voice & Drive). Powered off the phone, charged it fully, then powered back on. Its been running on the same charge for 24+hrs now and reads 68% battery remaining.
So check the apps you have installed, some use background data, and might be causing problems...

And your phone is the definitive guide for what Android OS usage is? Maybe his phone woke up those services for a period of time longer than normal.
The answer of "lol looks wrong root and install kernel" is terrible advice when so little information is given.

A longer battery graph would help a lot. If yuppy want top search XDA there is a free app called better battery stats that will help you diagnose if something is running in the background eating battery or even if your phone I'd properly entering deep sleep.

See now it is much easier to see that you actually do have a problem and what it is. You have the wakelock problem as you can see from Better Battery Stats which falls under Android OS on the other screen. It also appears that you have somewhat weak signal which could cause the wakelock to drain battery even more. There's not much you can do about that wake lock, some kernels have patches for it but those have their own issues as well.

Could I just install any kernel on stock android and be OK with it? As I've said I've no idea what's best for me; just something nice and clean that doesn't have issues like this. I live onsite where I work so my WiFi is pretty much on all the time if that helps in anyway whatsoever
I'm gonna let it run down completely tonight and charge it, but I don't expect it to help much.

I never told him to install a kernel. The advice I gave is to do a reset then I asked if he was rooted or running a custom rom or kernel because that might of been the problem.

Fully charged overnight, battery still sinking like a ship. 45 minutes and I'm already down to 94% already!
Idiot question; will installing a kernel just solve this? For now as a new guy I'd like to keep it as stock as possible before fiddling with it.

The battery on the n4 seems horrible.
I'm completely stock I just got my phone yesterday, I charged it to 100% now its at 64% battery with only 47 minutes of screen on time.
on the s3 I would be around 83% with 47 minutes of screen on time.
I'm gonna unlock the boot loader and root soon and try Franco kernel I've been reading good things about it.
Sent from my Nexus 4 using xda app-developers app

The battery life on the stock kernel isn't great because the CPU management isn't optimized well. It ramps up the CPU (frequency, number of active cores...) very easily and keeps it there long, which removes the occasional lag but sucks more battery. Flashing a more battery friendly kernel would definitely help you if that is the root of your battery issues and not a badly coded app.
Franco's kernel is a very popular one, and very battery friendly compared to stock (and that doesn't mean you lose performance). It is the one I'm currently using. Most people report of screen on times of 4 or 5 hours. With not so heavy usage and wifi (not 3g) I can also pass 5 hrs.
To install a kernel you need to unlock your boot loader and install a custom recovery. No need to root, but.. why not since you're at it
You can try different kernels with the stock ROM. You don't necessarily need a custom ROM. Just be careful to read the dev's OP and instructions, and definitely not to flash a kernel for another device.
Also another thing that reduces battery is your mobile data, if there are a lot of programs that sync on the background. You can use a program that turns off your mobile data when your screen is off and switch it back on just for a sync every xx minutes. Juice Defender is such app, though I like to use Tasker for that. If you use Tasker and are interested in that project, ask or send me a pm. It works great.

Anyone have bad battery life on g2? Any fixes?

Has anyone been experiencing bad battery life on the g2? When i first got it a month ago it was amazing easily getting 50+ hours with about 6 hours screen time. But over time its been getting worse. I already did the whole stopping the carrier iq and all that, it still doesnt help much. Now when i go to sleep and wake up 7-8 hours later my battery drains 50% or something like that for no reason, no wifi or anything on or synced. I did see some posts about people experiencing bad battery, this phone is supposed to have amazing battery life whats going on? I rooted my phone, still on stock rom, wondering if anyone has fixed their battery issue. Would installing a new rom like aeon v3 help improve battery like its supposed to be? Its getting frustrating, my gs4 had worse battery but at least the standby times werent as bad as they are on my g2. Any fixes for this?

There has to be something running in the back ground draining battery. If not try finding a battery Conditioning Application

Based on the above it could be a few things.
If you want to check a few things on the phone side you can:
- install GSAM Battery and let it keep an eye on what's actually using your juice. Then either remove, modify, adjust settings, etc, for whatever is using it. If it's an app... delete it. Reinstall it.
- You can try a factory reset
If neither fix it then you can try another ROM, but if your battery is just as bad with a factory reset I'd lean towards the battery. Maybe you have some bad cells.
I've had mine for a bit, and I only lose a little bit if not touched overnight.
My current setup:
- Madhi 4.4 KK ROM (1/18 build)
- Obviously rooted with the above
- Greenify on all my non-necessary apps (hangouts, weather and one other app spared from this)
- All my apps auto-sync features are disabled since I just run it once in a while, and things like mail / etc I don't need push anyways
I get pretty solid life even after a few moths of use now.

first, install betterbatterystats and look for wakelocks, try reseting the device. batterylife also depends on how you use the phone...i can get 9hrs on screen time reading books with still 15% left or drain it in 3-4hrs playing games.

Yes i have downloaded and used gsam battery app. I dont see anything unusual in my stats, also using better battery stats, its been in deep sleep for most of the time, and it doesnt say the phone was on or running when the screen was off. But for some reason i wake up and my battery is decreased by 50% again....I am using greenify and hibernating alot of those annoying apps. I am stopping apps that are running . And on the phones battery manager android system is first with 34% but it says its only been running 11min, and no gps is listed. And my screen on time was 2 hours those are what i foudn when i woke up with 20% left, at night it was 70%. I seriously think my phone is messed up when im using it its not that bad, but for some reason when i go to sleep and leave it alone it dies for no reason....

my battery has a problem too..
when my phone is idle sometimes the battery level increases by 1 or 2.
when im playing heavy games like gangstar 4 the battery decreases every 2 mins and the temperature reaches 40°C. and when im just browsing it decreases every 3-5 mins with a temperature of 34-36°C. and when im watching kuroko no basket (wifi off) every episode just consume 2-3% of the battery (24 mins. = 2-3%)
and the temperature is about 28-30°C.
I think my battery drain problem depends on the temperature

Only get ~2 hours of on screen time - "Android System" battery drain

I am on the latest 7.0 beta, T-Mobile version, I am getting pretty frustrated. I only get ~2 hours of on screen time. Right now at 30% and Android System has used 1350 mAh and CPU total is close to 5 hours.
Attached some pictures from yesterday and basically the same exact thing - maybe one of the packages listed is killing the battery?
I know there are a lot of posts about this issue but nothing that I've found useful unfortunatlely.

Did you try a factory reset? That help me get good battery life.

Been thinking about doing that, but not sure why it got really bad all of a sudden. I could get 3 to 4 hours before.
I think I'll wait until the official release is out and then do a reset - hopefully it comes out soon.

Still on 6.0.1 & Android System is my #1 battery drainer.

I am getting pretty fed up. Thought the new updates would make it better but no go for me.

If only you got root, I strongly recommend using Myandroidtools/disable service. Samsung roms sucks pretty bad, I have never ever experienced something like battery drain on other phones. Since I disabled 80+ Google Services and some samsung bloat, android system takes about 2-4% drain after a whole day. I am using Renovate on nougat.

Looks like a lot of you are very unlucky. My battery life is superb! At the end of the day I still have ~35% battery remaining. I recharge every night regardless of how much battery I have left, so it does me just fine

I would strongly advise to stay away from any of those 'fancy' package disablers.
They do no good and often deteriate things. I have on average over 8hours SOT and never used disablers.
Most Samsung apps don't put any drain on the battery. It's things like Facebook etc that hog resources.

Yeah, if only i got Facebook apps installed. I have fully working locations, notifications and other stuff - most of services I disabled are feedbacks, silent loggers and stuff I dont need or use. Only corrupted app is Gmail - which I don't use.
I got sync switched on, lots of calls, auto brightness, voice assistant and usually get 5 hours SOT during my usage which isn't bad at all.

So not sure what did it, but I installed Greenify and also changed from 1080p to 1440p and I get about 3ish hours on screen time. Still terrible but will do for now.
My phone also feels faster after changing resolution back to 1440p. So weird.

Disable ubication and always on display.

I mean location. Aod takes almost 40% of battery in 24 hours.

I remember Samsung saying it only consumes a couple a percentage points.
This article tested and it's nowhere near 40%. And I use the phone about 15 hours before it gets charged again so it should have a huge impact.

Okay, stop reading useless news and try it by yourself. Phone dont go fully in doze mode with AOD on and keeps light and other sensors on like proximity to put more or less light in the aod screen. You are complaining about **** battery and I am telling you that I have tested how aod can take 40% of battery in one day. You really believe samsung? Come on...

I really don't think you're right as that's not my experience either. I cited the article because usually the tech websites have some experience - my anecdotal data, or yours, doesn't carry much weight.
As posted before, my screen time has increased and keeps going up. Got near 4 hours of on screen time today. Greenify must have killed a process that was putting the CPU on overdrive and which showed up under Android System. I shouldn't have to take the time to find fixes however since Samsung and the Doze feature should be doing this already.
I appreciate your advice, no need to get upset we're just having a discussion...

I don't really see a discussion in the fact that AOD uses a lot of battery if you keep it on all day, it's pretty much guaranteed that AOD is the main culprit. And your own experience with your phone and its settings is worth a lot more than the experiences from some tech website. Everyone's phone/settings is different.
