List of known issues - confirmed on some phones

Can we put together a list of known issues with this phone for those of us who are thinking of switching so we can see everything in one place instead of having to sort through all the mess to find the issues and resolutions. Thanks
This list is just a copy and paste of the main points listed in the first 5 pages so far to save you some reading. Its just a summary, nothing more.
- vertical lines on some models with specific box date
- dead red pixel on some models
- some models has odd camera flash light, when powering off
- occasional errors when playing media on the sd card
- battery has stayed stuck at "100%"
- WiFi settings shows connected to the correct network but keeps scanning (Power saving mode problem.)
- lock screen locks up me sometimes
- wouldn't stay powered down while charging
- it takes quiet some time to charge up
- it's always warm even when not it use, but it gets super hot when charging
- screen lock bug
- take a pic, then tap the gallery button in the camera app, share to facebook, will not upload, says cannot locate pic. go to regular gallery, upload pic same way and it works fine.
- issue with the display staying on
- games freezing up and crashing after about 5- 10 mins of game play
- trouble with data when connected to wifi.
- wifi works but the 4g will not get internet access.
- music player other than orginal makes all kind of funny things skipping ,play not play or stock
- rebooting

Same here, rebooted on its own after about 2 days of up time. No other issues besides that.

so, off all the stuff i've read in the forum thus far:
the list is something like this:
- vertical lines on some models with specific box date
- dead red pixel on some models
- some models has odd camera flash light, when powering off
lags and some apps performance, or network speed stuff doesn't count
anything else missing?

minor heads up
lets keep this topic only for confirmed issues.

One thing to add- occasional errors when playing media on the sd card. I'm having a hell of a time with Doggcatcher & some music players saying that the media cannot be read.

that's a good one
and it sounds very familiar, back in the SGS1 days, there was similar problem.
using another media player should avoid that problem

Yeah it works fine with PlayerPro, but I'm still trying to find another podcatcher that I like. I'm kinda pissed that I paid almost $7 for Doggcatcher & now it barely works >:|

So far my only issue is that the battery has stayed stuck at "100%" twice now (only had the phone for a week obviously). Both times it was in the morning after the phone had charged all night, and then I take it with me for school/work. I used it for a few hours at school and it stayed at a 100% so I took it by T-mobile and they hadn't seen that before.
They did the same thing I did which was remove the battery and restart the phone. After that it read correctly (around 76% or something). Still I don't want to have to pull my battery every day after it gets a full charge. I'm going to see what it does tomorrow in the morning and go from there....anyone else have this issue?

please report that bug directly to samsung on the stickied link

Haha yeah I can deal with it from time to time maybe, but I don't wanna be doing every freaking morning haha

I also have the 100% battery bug. I don't have to pull the battery though, just doing a reset by power off/on works to clear it. It *is* kind of annoying though...

I have seen this as well. It happened the last two mornings after charging overnight.

I have same issue. keep showing 100% battery indicator.

Wow lots of people having isSue wiTh the 100% battery thing hopefully that getS sorteD soon.
Edit: I HATE typing on this freaking iPad sometimes!

I saw the battery stuck at 100% as well on mine. Another thing i noticed that i have the WiFi ON all the time. So while i'm in office it is connected to the WiFi and the phone sits in my pocket for about an hour or more before i actually use it (using another phone at work), so after i wanna use it and it shows the WiFi connected symbol but no connection. Go to WiFi settings and shows connected to the correct network but keeps scanning. Turn Off WiFi and turn it back ON and its running again. Although i did not noticed this issue at home. Is it that at home my phone is always on table and not in my pocket....is it something to do with my my pocket

Power saving mode problem. When activated, it turns off gps, wifi, blue tooth etc.. (Whatever you choose) at specified battery level. However, when power is recharged past the set power saving mode point it doesn't turn these features back on. So annoying.
So when fully recharged, you have to go back and manually re-enable your gps, wifi, screen brightness etc..
This seems like a software issue, do the other brand gs2's have this problem?
**Also have the 100% battery bug.

My Galaxy S II wouldn't stay powered down while charging. Everytime I turned the device off while charging it would automatically power back on. I honestly wasn't sure if that was simply the way the phone was designed (which would be odd), but sure enough at the T-Mobile store today we opened up a brand new Galaxy to see if it would remain 'off' while charging. Sure enough, it could.
Long story short, I have the 100% battery malfunction, and an "unable to charge turned off" issue. Swapping out phones at T-mobile as we speak Another GSII btw, even with these annoying issues its a great phone. I think (hope) I just got a lemon?

Removing Bloatware aka "what can I do to get better battery life?"

So I think by now everyone has realized the battery life on our A100's is mediocre. I've actually been pretty content with the usage I get out of mine. What I'm not so thrilled about though is the idle usage. I'll leave for work in the morning with my A100 at / above 90% battery and come home after 6pm with it completely dead. I have wifi set to turn off when the screen does, any app I have that has a sync option is set to 6+ hours, and I've stopped using live wallpapers. Every other electronic device I have can usually last a full day when not in use(my old netbook gets 3 hours of use on battery but 2 days while sleeping).
I've started looking into the "bloat" / OEM apps installed by Acer. Nidus, sync, socialjogger etc... My main questions are; what can be removed, what can I live without or would be better of with a 3rd party app, and which Acer apps can possibly be causing the idle/sleep battery drain? This thing should still last a full day while sleeping, shouldn't it?
Any suggestions? Anyone else have this issue? Thanks!

You could try using Bloat Freezer to freeze apps. I have alot of the acer stuff frozen, and with it in standby, easily goes a day. Things like socialjogger, acer init, etc.

These are the apps I've completely removed from system apps, made a backup of course..
AcerClockwidget.apk&odex
Agendawidget.apk&odex
Aupeo.apk
Clearfi.apk
DTG.apk
LinkToFacebook.apk&odex
MusicA.apk&odex
MyLocationWidget.apk&odex
NemoPlayer.apk
Planner.apk
SocialJogger.apk
Solitaire.apk
Xt9.apk
You can also remove appinapp butyou will loose the games multimedia app I use that so kept it.
Battery life hasn't been that bad on mine. I expected worse, I just picked mine up last week and after reading reading reviews I expected worse.

WOW! I can use mine all off and on all day and don't have a problem. There has got to be an app that you are using that is destroying your battery when idle. If I don't use my tablet all day, it will last 2 full days (with wifi kept on).

That's what I was thinking. I get a decent amount of usage from it; it's when I'm not using it is when I feel like it drains the most.
I started freezing apps last night and let it charge overnight. I've still got to go through my apps and remove a few I don't use, and check to make sure they're not syncing too often. Do you all leave your gps and wifi on all of the time or have them shut off while the tablet sleeps?

My settings are to never turn WiFi off and I always leave sync on; I like getting notifications and app updates. I have a weather app that updates every hour and Pulse news that updates every 4 hours.
I also always leave my GPS on, but there aren't many apps that use it while it is not in focus, so I rarely ever see GPS pop up on my battery usage list.
I do not use a live wallpaper.
I found that with wifi on, my tablet drains about 1.5% per hour when idle.

I suggest other than setting wifi to turn off when screen is off is to use a wifi toggle widget. You really never know what happens when the screen is off if your wifi is really turning off. Wish it was built in to the quick launch though like some Honeycomb tablet.

You can also use setcpu to setup profiles so that when the screen is off the processor stays at a slower speed rather than jumping into high gear when something wakes it up to sync. I've been able to go days without having to recharge (but I only use it for reading books, listening to the music I have on google music and play order and chaos every once in a while). I havn't touched my a100 in about 4 days and its sitting at 62% battery power.

here is my usage, I never turn off wifi no profiles

I don't necessarily think you need to remove any of the stock app. My wifi is set to turn off when screen is off, GPS off unless I need it (apps like facebook will use it when you open it since it tries to get your location for checking in even if you're not checking in). Gmail is left at default but other mail is set to never (I just manually sync it when I open it).
If you wanna go a step further, you can install a wifi on/off widget to completely turn it off just incase an app is trying to use wifi.
With my setting my battery drains about 1-1.5% an hour when screen is off. IMO the screen is what uses the most battery. However though after conditioning the battery for 3 cycles it's been lasting longer.

I was just about ready to return / exchange my a100 so I did a factory reset on it. Lost track of time and forgot to, so I just decided to boot it back up and play with it. Left it alone at around 70% yesterday afternoon, came back home at 7pm today and to my surprise it was at 40% battery remaining. Must've been an app or setting I had that was killing it.
Probably end up hanging onto this awhile longer. Great tablet for the money!

Also can freezing apps brick your tab as well? Or does it defrost itself after boot?

I think with the 1gb ram on our device there shouldnt be a need to freeze any app and it doesnt defrost itself on reboot. Atleast it shouldnt.
Also I found for the most part if an app can be deleted it will let you delete it by dragging the app icon in the upper right in the app drawer. This is probably the safest way to delete rather than doing it in root explorer or TU.
This might be a dumb question but is it possible you have wifi issue that i've had on 2 a100s which will prob cause it to use more battery as its trying to work harder locking on.

It seems for the moment my battery issue was resolved with a factory reset. I have nearly the same apps on it now as before and my a100 hasn't been dying overnight. Don't believe I've frozen anything this time around either.
I don't think ram has a whole lot to do with it. I just figured some of these apps were starting themselves or syncing often, causing the battery drain.

Do you have a lot of widgets that requires syncing like youtube, twitter, weather, facebook? Those are the apps you probably what to check. OR you can just turn off wifi if youre not surfing or streaming.

Here's mine with wifi turned off. It was at 89 but I had to turn on wifi so I can find a screen capture app in the market. I have lots of apps including facebook, twitter, weather widget, which cant sync cause the wifi is off. Have not removed any stock app. I know this doesn't really answer what you asked but I'm just thinking something else might be wrong other than apps. Maybe its your battery not holding correct charge. Have you tried calibrating the battery?

I tried calibrating the battery the first time around. This time (after the reset) I haven't done anything special and have so far been getting 2 days of idle/light use before needing a charge. Satisfied so far. I was mainly concerned that I wouldn't be able to go on a trip without it needing a charge while sitting in my bag for a day without use.

How can I track down my battery drain?

Leaving my OP in place, but I have rewritten the description with much more detail and pics here
http://forum.xda-developers.com/showthread.php?p=25401417#post25401417
I suggest skipping to there.
I am looking for general tips here. E.g., not asking you to diagnose my specific problem so much as give me ideas of what else to check or try.
Lately I have had unexplained (to me) battery drain. Yesterday I lost about 25 percent in an hour while the phone idled. It is not a constant thing, though. I can go an hour and loose 1 percent then loose massive amounts in the next hour.
Now, i have searched, but I have not found anything that applies to me.
I have:
Tried a different radio
Tried a different kernel
Reflashed my rom
Phone is entering deep sleep according to cpu spy
There are no unusual or excessive wake locks according to better battery stats
No apps are using a lot of battery.
I am in a low signal area at work, but putting the phone in airplane mode and dissabling background syn does not stop the drain.
Ideas?

might be your phone is loosing signal? i would check the battery stats in the settings menu to see if you have a poor mobile signal.

I do, and on reflection it is a possible culprit since I added it recently.
Didn't occur to me since it was producing no wakelocks and the battery stats did not showing as using much battery.
I shall turn it off for a bit and see if that helps. (unless there is some other way to test if it is the problem first.) I am off to the search button!

This is from yesterday when i set it down unused for about 90 minutes. The amount of wakes seems liek a lot, but it is similar to what i see when i have far far less drain, so I don't think that is the problem. I didn't get the app list screen, but out should screen as the only major drain with about 2 minutes.
I know it is shows poor signal strength, so immediately after that shot I put it in airplane mode, turned of sync, and rebooted. The battery continued to drain and graph had the exact same slope under those conditions. (Forget to get a pic though.)
Sent from my jitterbug using tapatalk.

System panel paid version with monitoring enabled is the best for tracking apps using CPU.

OK, still working on this.
To recap:
When the screen is off, and no apps are running I sometimes get inexplicable battery drain. This is occurring under conditions when I should be experiencing little or no drain at all. I say this becuase:
The screen is of and no bakground apps are running
the phone is NOT awake and IS entering deep sleep (as confirmed by cpuspy)
there are no unusual kernel or partial wake locks
there are no apps listed as using unexpected ammounts of battery
This is not a universal problem. The phone *often* behaves as expected. I can leave the phone off for an hour and see a 1% or 2% drain, and I am happy with that. However, sometimes, randomly, it goes nuts on my.
This graph from a few weeks ago shows what I mean. Look in the green box. The phone is sleeping, and the screen is off. The graph starts as a flatline, then, all of a sudden, it begins to drop precipitously.
Here is a graph that shows the battery dropping at the same rate whether the phone is awake or sleeping:
I have gone the following to try and narrow the problem down:
Done a completely fresh install of my Rom including a system wipe.
Tried two kernels (the aokp default and several relases of Franco's
Tried a different radio
Activated and installed a new sim card
I have come to suspect that the problem is network related. When the problem starts, sometimes going into airplane mode and back and/or toggling 2g only temporarily fixes the problem.
I suspect that something is happening with my connection to T-Mobile that keeps the network running and draining power. This is pure speculation, but it is all I can think of.
I installed juice defender (which I had not been previously running) and noticed the that, sometimes, it didn't turn of data when it should have. I also noticed the following two things happen:
I do not believe it is a rom problem, since if so, someone else would be reporting this. It might be an app problem, but if so the app is draining battery without a wake lock and while the phone is in deep sleep.
It is not exchange (as was suggested in this thread) since it continues when I ev my exchange account.
I have no idea what else to do or try.
Since it happens at random and takes a while to identify, uninstalling one app at a time to test for that could easily take months to narrow down a misbehaving app.
I know it is not a hardware issue since last month I got this:
That was with AOKP and Franco (earlier versions obviously)
I have google searched till my fingers bleed.
I am a long way form being an expert, and I suspect I may have overlooked something obvious.
Please, any thoughts??

Damn you definitely have a major issue and I don't know what it could be. But when my phone sleeps itstays dead flat with no awake bars, and drops 1% every 3 hours.

1. Calibrate battery
2. If you really wanna find the problem, install the rom with no mods or apps and run it and see if it still happens. Then add back each mod/app one at a time

While I appreciate your effort, this is remarkable unhelpful for the following reasons:
1. "calibrating" the battery is a myth and doesn't actually do something. Even if it did, it would not explain the symptoms I have described. I have been around xda long enough to know it is the knee-jerk reaction to any battery question, but it is not relevant here.
2. Since the problem occurs at random, and sometimes takes hours to show up, (For instance, last night I charged to full and tried to catch it happening. For 4 hours nothing happened, it behaved perfectly. Then I went to bed and it immediately started to fall and was dead by morning) and since I have over 100 apps, your suggestion could easily take *over a year* to follow. Believe me, I have thought about it, but I started this thread hoping for ideas that would allow me to avoid it.
Here is that chart for last night.
I had about 1 hour and 30 minutes screen on time with 65% left when I went to bed. When I woke up, phone was dead.

Mine often does that. But sometimes it doesn't. It is the fact that it happens seemingly at random that makes it so annoying and hard to track down.

I would replace the battery
One thing you haven't rulled out is that the battery itself is bad.
Have a friend you could swap with for a day, or at least long enough to see if the problem follows? If your battery drops on their phone that is also a good indication.

The thought has occurred to me, but unfortunately, no, I don't have a friend I can swap with. And really, since I have had the phone less than 3 months, the battery *shouldn't* be bad, but yeah, defective products happen.
If I cannot find any other cause I will likely order a new battery and see if that fixes it.

1. yes battery calibration does make a difference.
2. ok, so an app can't run a process at random? especially when you have "over 100 apps"? Run the rom stock and see if it still happens, or even run the stock rom/kernel. if you don't want to try this then why are you asking for suggestions? christ

We'll of course it can. That is kinda my point. If I go one app at a time waiting for it to "run a process at random" I am talking literally MONTHS of testing. I would have to wait many hours, if not days after installing or uninstalling an app to be sure whether or not it made a difference, then move on the the next. This is simply not an option. I started this thread in hopes that a realistic and doable solution might exist that I was unaware of.

Sorry to have put you out so much.

You mentioned you recently installed exchange sync. Did turning off sync remedy this or have you not tried disabling all sync features?
One other thing to check is the background data usage of your apps. You'd find this under 'data usage' and make sure you enable the wifi tab so you can see data usage on wifi.

My battery also drains at a rate similar to yours however I'm on the CDMA version. Hopefully you can figure out what's going on with yours.

Rapid Battery Drain - How can I improve?

My battery seems to be draining quite fast. I have removed a lot of bloatware, but I'm not getting the type of performance that others are getting.
It has lost 70% in 5 hours just doing a little browsing, watching a 20minute video and playing a game for half an hour. This was with Wifi on, and mobile data switched off, and background data switched off too.
I've had the device for a week now and I've charged it every day.
Any Ideas on how to improve it?

If you use autobrightness try using an app like LUX auto brightness instead.

My battery seems to be draining quite fast. I have removed a lot of bloatware, but I'm not getting the type of performance that others are getting.
It has lost 70% in 5 hours just doing a little browsing, watching a 20minute video and playing a game for half an hour. This was with Wifi on, and mobile data switched off, and background data switched off too.
I've had the device for a week now and I've charged it every day.
Any Ideas on how to improve it?

If you are rooted get wakelock detector that will tell you what's up

Thanks for that, I did have it on Auto brightness for the first few days, but the last few days I switched it off just in case it was that, but the problem remained. I will try LUX auto as you suggested.

I am rooted, and thanks for the suggestion of that app - I will get it right now and test with it today, I'll let you know later how I get on.

My guess is a corrupted media file somewhere which is causing your media server to prevent the phone from going into deep sleep. When you go to settings , battery, is media the no 1 juice sucker?

Yeah I got rid of the radio and media player from one of the homescreens as they showed quite heavily in wake up time. but the battery still kept draining fast.

Just buy another battery and enjoy the pleasures of experiencing a QHD beast I have 3 batteries (2 standard) and managed to strike a freebie on the 3rd battery ..

I wouldn't mind, but I just bought it 8 days ago, people are experiencing a lot longer battery life than I can.
Immediately just played a game and look how much has gone.
Why is Android system using up so much? I've even got location switched off and Google search etc. is deleted.

If 're not using Xposed Frameowrk for tweaks, looking into enabling ART - I did that and my battery life has been impressive.

I did try that, but it didn't work and the phone was a bit laggy. Why would android system take up 15% of whatever the battery uses? I'm getting so frustrated, I might do a factory reset.

Here is the picture of what is being used, down 40% in such a short time. :

Aosed to make things smoother not laggy
Sounds like you have something eating up massive resources.

Must be, but I don't have any idea what it is:
Here is a screenshot a few minutes after the last screenshot - another 10% down, and I watched a 8 minute video:

How long has that screen been on for?

A shot in the dark:
Do you skype? Skype was draining the battery down in the Nexus 7 2013 even when you were not using it. I disabled it and the battery improved greatly.
Another option:
It sounds to me that there's an app that is draining the battery down a whole lot. I would try to isolate that app (by deleting each one you downloaded one at a time) until you have found it.

I don't have skype, but I like your idea - I've gotten rid of almost all the bloatware stuff. What I think I'll do now is charge it to max. DO a factory reset and not allow Google to start downloading all my apps again.
Funny thing though - when I charged it last night and unplugged it for 3 hours it only dropped a couple of percent. It started dying rapidly after I opened up a few other apps.
What I'll do now is charge do a factory reset, then switch it off, then charge to max before turning it on again. When I first got it, it turned on as soon as I plugged it in. did the same happen for everyone?

What you might want to do is download Greenify on the play store. This will tell you what apps are running in the background and then it will turn them off (hibernate).

Make sure that you leave the battery charging for about 10-15 minutes more after your cradle light turns green. Sometimes the battery isn't fully charged despite the cradle light turning green. 30 minutes on a game shouldn't be using that much battery consumption.
I usually get about 10-12 hours or more on each of my batteries ( video calling, chatting, games and my 4g is turned on 90% of the time
Try this from Google Play

You can read their reviews and install the app but don't download too many battery monitor apps Keep us posted after a few days of monitoring Good luck :good:

Huge battery drain and phone getting hot

Hey guys,
I buyed my g4 ~2 months ago, and for some days the battery drain is sometimes huge (30%/hour) and sometimes I'm nearly losing 0%/hour... The android core apps are using 31%, the screen 23% and the play services 17%... I'm using the standard rom, didn't change anything, didn't root my phone... And I don't really like to factory reset my phone. Sync is off, only Wi-Fi with 3/4 bars and didn't use it, but lost 30% in one hour... Would be nice, if someone could help me...

Seriously? No one has an idea? I'm kind of disappointed

Do you live in an area where the signal for calls and texts are bad because that can cause battery drain...

Also even though you are not rooted you can still install greenify to put some apps to sleep , and antivirus , facebook and facebook messenger can also drain your battery quick also have you sideloaded an app or game because sometimes an app from somewhere other than the playstore can cause problems..

Try wiping the cache in recovery. This will retain your data.

I have the same issue, but it only started after I rooted my G4 (H811). Today it went from 50 to 0 in 3 hours, while I was asleep...

Can you check to see what is consuming so much energy?
Maybe there is some program, or memory leak, or something that you can identify as the culprit.
This is assuming it's something running on the phone's CPU sucking all the power. A much easier thing would be if your problem is low signal strength, because that is a tangible thing and easy to see, where you don't have to try to track down the mystery app.

I would recommend to wipe the phone completely. I had the same issue and it was an app that caused horrible batterydrain. If it doesn't help and the signal in your region isn't that bad it might be a hardware issue and you should ask your retailer.

try to use your phone in flight mode,
if your battery still drain, maybe its because the battery (hardware) or the wrong calculation of precentage of the battery.
if its not draining, its might be caused by your bad signal, as i had nowdays,

I had the exact same issue. I did a factory reset and it helped a bit (it didn't get AS hot as it did before). However, I just upgraded to 13B and the issues are completely gone. Although 13B seems to be running better altogether, I think the MAIN reason why mine was getting hot is because I had LOCATION set to "High Accuracy (GPS and networks)". I live in an area where my connection constantly changes from LTE to 3G, even down to 1X. My phone was trying to find my location all the time and it went nuts whenever it changed to 3G or 1X. Right now, it's set to "Battery Saving (Networks only)" and I've had NO heating issues. My battery is lasting twice as long, or so it seems.
Hope that helps.

you have bad apps misbehaving or else settings wrong, remember, temperature is tied to battery drain, solve the temperature issue and you will solve the battery drain, my H815 gets crazy long battery life, I cannot run it down in an entire day! - right now my CPU temp is 85 °F (29 °C) with a few things running, such as music

I sometimes spontaneously get an app that will drain my battery faster than I can blink... I force close it when I identify it and all is normal into some other app decides to behave the same.
First was a Kohl's app then was ESPN
