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?

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.

Weird Battery Behavior. Any solution? Or time for an RMA?

I have had this phone for about 2 months now and everything has been exceptional with the phone. Have seen people complain about the battery life, however it has been really good as far as my experience is concerned. However since a week I have seen the battery screwing up a lot... A LOT.
I always used to charge my phone daily in night. Plug it in..set an alarm of 3.5 hours (yes it takes 3.5 hours to fully charge from less than 10% stage) wake up..turn charging off..sleep back. Okay, some of u might think it is stupid but can’t risk of leaving it on charge the whole night and burn my phone. Anyhow, so, since a week what I do is I charge my phone whenever I want (read it on a few thread and articles)..be it 50%... 80% or even 92%. I just make sure its 100% whenever I leave home.
But something weird has started happening... The battery percentage keeps on changing.. For instance:
when I unplug it..its 100%.. within minutes of usage it drops to 99..then 98.. then 97 and suddenly it rises back to 100%. (Pics attached)
Sometimes when its on charge and I come to check SMSz and reply them.. battery % suddenly drops.. e.g: if its at 99%... it will suddenly change to 96% in a second and in a minute goes back to 99% .. so on and so forth. And sometimes even when its charging..if it is at 80%, it will suddenly shoot up to 100%. The percentage doesn’t change even after a reboot. Weird, isn’t it?
Now the most weird issue, since yesterday the battery life and dropped to 50% less. I used to get 4 hours OST and now I hardly get 2 hours. During night, the battery used to drop 2% in about 6 to 7 hours and yesterday it dropped 15%. There was this one time when it dropped 9% in 6.5 hours (pics attached). Tried seeing through Wale Lock Detector but there were no Awakes during deep sleep. Too weird :s
I don’t really know where did I phuck up as I haven’t installed any shaddy apps or something. Please advice.
My phone info:
All stock. No root (and not looking). No custom Roms whatsoever.
TL;DR... Battery acts weirdly. Shows inconsistent percentages. Suddenly shoots up. Suddenly Drops. And now the On Screen Time has reduced 50%.

It sounds like it's nothing more than a bug.

Thanks for ur reply. How to figure it out? And measures should be taken? Any suggestions?
this has really kept me worried since a few days.

This is "normal" for the N4, and the most/all of them do it. Unreliable drivers, or a hardware fault, not sure.
Here are other threads about the various battery bugs, but there are many more:

I know I searched many threads before posting and mostly had the Shooting up issue only, when charging.
Anyhow, this normal behavior has reduced my battery life a lot.. which I am not liking .. What to do?

Both my N4's (different H/W revisions) have been doing the 100 to 98 to 100 thing as well since new. Battery life is still excellent for me. An RMA would probably do the same.

Happens with my nexus 4 too. But this hasn't reduced my battery life at all...

You're pretty much stuck with that phone as you only have 15 days to RMA a device, your only option would be to send it into LG for a repair. My battery has acted up like this once so I stopped using the stock charger and it hasn't happened since.

Rebooting might help. Could also be an app that updated that now doesn't play nice. You could try a factory reset just to clear out some crap but I'd back everything up just in case first. Not sure if a factory reset deletes all your user data in memory or not. I only did it once right after I got the phone so can't remember. Hate to lose all your pictures, files, etc. that aren't backed up.

It's normal. The N4 isn't great about showing the exact battery life. In fact, what you see isn't the true percentage, it's an estimation. Don't worry too much about it!

This is a question I can't answer along with any facts. I tried disabling it for 2 days and I noticed the OST reduced from 4 hours to 3.xx hours. May its placebo or something but then I enabled it...thinking if it's not doing any good then it's not doing any harm either.

Hmmm, I didn't know that. But why is that? Any apps or something to show the exact battery percentage left?

Happens to me once in awhile. Do a quick reboot, and if that fixes it, I would not worry too much.

Hmmm..
Yesterday when I woke up in morning.. the battery lost 2% only in 6 hours. I felt SOOOO relieved that my "good battery" is back. But who knew what was to come... today I woke up after 7 hours and the battery lost 15% .
My usage is always the same. I force close all the apps I use daily and turn wifi etc all off. So i doubt if its any app.

[Help] Battery problem

My battery is draining too fast after upgrading to android 4.3. Even only on 2g there is 1% decrease in battery almost after every 3 minutes. But with screen off it will remain almost at 99% after even 12 hours or more. But when I start using the phone for something like even navigating through the settings the battery drops 1% every 3 minutes or even less. My handset is about a month old. I am from India and running the ML4 android 4.3 recently released by Samsung. There is no wakelock when the screen is asleep. The phone screen consumes between 60 to 90% of the battery or more. I factory reset it thrice since the update but with no effect. I am running the 4.3 update for about 3 weeks now. I also installed Greenify, battery doctor, juice defender etc to save battery but there is no improvement. I installed the same apps that I installed on the 4.1.2 firmware but the battery is draining quite faster in the 4.3 version. I also freeze almost all bloatware using Titanium backup and even uninstalled some like Google Books etc. but no use. I don't use wifi or wifi hotspot at all. I rarely use bluetooth. GPS, location, etc off. I even freeze Google Play store, Google play services and Google services framework. No multi window, no smart stay, no s voice, no ripple effect, no live wallpaper, etc everything off but still the same. If there is anyone facing this issue and has already found the solution, please help me out.

This is funny! You mean to say that the upgrade to android 4.3 has damaged my battery? The battery is not even 1 month old as I mentioned in the first post. The battery is very good on android 4.1.2...... As I mentioned in the first post, there is no battery drain when the screen is off. Even after 24 hours the battery is 99% from 100% with screen off. Why should I checked for wakelocks when the battery is fine on screen off? I did checked it to be sure but no wakelocks. The battery problem is when I use the phone, the battery is draining abnormally when the phone is used. Anyway thanks for your reply.

Using BetterBatteryStats will nevertheless help you to find out which process is consuming your battery…

Yes, 4.3 upgrade downgraded my battery life about 20% when I am using my phone. On idle it is better about 10-20% also compared with 4.1.2. It is useless to do factory resets or other nonsense. Just it is as is.

Okey So Firstly I rule Out Few Assumptions Made By Some Members(No Offense):
1) As thadoukuki said battery Drains only while using the phone and not wen its idle that means its not a wakelock for sure.
2)Secondly as the handset n battery ofcourse, are just a month old i dont even assume it to be damaged(Trust Sammy)
3)Thirdly 1% / 3Mins is quite normal on extensive Usage but as you say its just while navigating around settings etc. den i assume its a bit high.
4) Now betterbatterystats is good to identify what consumes your battery but ive never been a fan of that actually.
SO according to me try to do some trial n error work .
Instead of Freezing apps through TB u can use Greenify Donate to greenify system apps and user apps as well. It Does same job as TB freeze but without that extra hassle.
Secondly Choose a kernel that you think is battery friendly for you like the one which gives you peace of mind(Oh Yeah Battery's Draining Slow!!)
for me i'd go for Boeffla or Googymax
Choose a battery friendly Governer for ur CPU(For me Boeffla kernel with Archi_ultra_power_save governer gives great results)
Check if CPU Touch boost is Enabled in Kernel Settings coz Touch Boost gave me good performance and responsiveness but even i had observed that battery used to drain faster with it.
Battery friendly Rom with few Tweaks by xda members is always better for me over Stock( ArchiDroid Is the Rom ive ever Used){Personal Opinion}
Ppl Say undervolting helps .....hmm maybe ive never Done it but as you are very cautious about battery you may try it (on your own Risk)
Lets see if that Helps
And Lastly i never Observed much Change in Battery drain pattern wen Coming from 4.1.2 to 4.3 so thats not really true.

Anyone experiencing faster battery drain on 4.4.2?

I updated to 4.4.2 a few days ago and am noticing faster battery drain. Just curious if anyone else noticed this?

Yup. Have tried factory resetting twice. Clearing cache. Disabling nearly everything possible. No avail.

Mine was draining a bit faster than normal after the update. I let it run all the way down, and charged it up, and it has been fine since then.
Hope it works out for you guys.

Camera bug = Battery Drain

I posted this in the 4.4.2 issues thread, but will post here:
EAS continuously running....I found this out as well after the update. I cant believe its low priority for such a major issue. I switched mine to manual just to be safe. I also found a major battery drain issue when surfing on the internet via LTE service.
Any way, I wanted to see if others could replicate my issue:
-Stock (non-rooted) S4 phone with the recent 4.4.2 update on LTE with 5 bars of service.
-I am using Chrome to surf the internet.
-I have Exchange and Gmail accounts. Gmail is set to PUSH and exchange is set to manual. (My hope is that having Exchange set to manual I avoid the EAS issue described above.)
-Majority of the boatware turned off
Scenario: While using Chrome to surf via LTE service I am literally able to see a 1% decrease in battery ever 2-3 minutes of surfing on the internet. Wifi is better, but still drains faster than 4.3.
Can anyone else try and replicate and respond back? I may have to do a hard reset to see if it will remedy the issue. :-/
Thanks,
Eric

Yes I have had worse battery drain with the KitKat update. Hoping for an AT&T update since we dont have the option to flash roms...

What are you actually seeing for battery consumption?
I have google+ at the top of the list with >30% use. Definitely new after 4.4.2 update.
Seemed to be ok for a day and then popped back up. I'm going to try to see if it's caused by 1st use of the camera.

I'm not using live wallpapers.
Rebooting the phone and avoiding use of the camera did not help.
I uninstalled all google+ updates that that has worked so far, but definitely not a long term solution.

Well I would up flashing the MK2 revert, then changed my mind and re-updated to NB1 (these two processes involved many full-wipes and even flashing a .pit file). Installed all my apps one-by-one. I'm now getting better battery life. Still higher than previous usage by Android System (usually ends up being 14-17%).
NB1 now works pretty damn well for me. Once we get root I will be able to disable some stupid things like the boot sound and charger connection sound, along with a few apps that just don't need to be running like Knox and Security Policy Updates...

Battery Life Thread - LS992 Specific

I want to try to work with other Sprint owners and see if anyone else is dealing with something similar.
I have a Titan LS992 that is having some software wakelocks thats causing larger than normal drainage when the phone is supposed to be sleeping.
I saw about 13% over the course of 8 hours last night when phone wasn't used. I even put it in Airplane mode to rule out Wifi/Mobile Data causing problems and it still lost a little over 1% an hour.
In my battery stats, Android System is what is causing the wake lock. It shows CPU total that is pretty high as well as Keep awake number that is high. Using GSAM is a waste w/out root, and there is no app that is showing up in battery stats that is out of the ordinary.
I've performed a full factory reset and still nothing. Prior to this I had used the "pm hide" adb command to hide a bunch of stuff and it seemed to have stopped this behavior than one night I lost 27% overnight and saw this behavior return. So I reset and left everything stock. I only disabled what I was allowed to via the App Info screens.
Has anyone else seen this? Does anyone know anyway I can try to track down whats going on w/out root?
I've attached some screen shots of battery stats.

I've not really got any stats for ideas. But I did find that LG Health took a HUGE hit on my battery. Once I retset that it went back to my normal. My phone idle is always pretty high like 30%+

I've been losing 10% an hour on average with LTE/3g, gps and Bluetooth running at all times but I found if I turned on background data restrictions it puts me at 5-6% per hour hope this helps a little. (Edit) I was looking at my cpu usage and found something interesting in over 35 hours worth of stats it shows I only hit deep sleep for 13 min here is a link to my stats that I'm referencing https://plus.google.com/117150330027523842650/posts/MqUWWNDsXbH

Hopefully an update fixes whatever conflict is causing this.
I've tried contacting Sprint and LG about it. Haven't heard back from either.

I have the same issue its breaking my mind i tried everything Lol. Barely 10 min of deep sleep during a Day

I usually can only get 10-12 hours before this phone dies. Its pretty crazy how bad the battery life on this phone can be.

When android os/system is spiked high usually a firmware reload is needed. If theres a corruption in the framework sometimes a hard reset wont correct the issue. Also scouring through settings and turning off things like day dream, always on and other misc features will help. Under network change from global to LTE/CDMA will help. I quit stressing aswith quickchatge 3.0 it takes All of 30 minites to top thw battery off
