[Q] Is there a problem with my battery?

Hi,
Is there something wrong with my battery? This is the second time it has happened to me .. last time I left it overnight at 45% and when I woke up the phone was off, so I looked in battery usage and saw that it fell to 0 right from ~25%, and today, I was in an international call, and the call cut off and the phone shut down. It wasn't hot at all, I checked.
Is there some bug with the software, or is it a problem with my battery?

Can you check in the setting menu, where the battery is used for? There must be some or one thing, maybe a constantly updating widget, which is faulty, it really take me 1.5 days before my battery is flat with internet on all the time, and 3 days plus with internet off.
On the other hand I had the same with my lg a while ago and after a flash it was OK.
Sometimes these kind of phones behave very unpredictable....

Oh I'm not worried about the battery life, I was putting it through a lot of use.. and I have a lot of widgets updating frequently
My concern is with the sudden drop from ~25% to 0 which has happened twice now

your battery might be wrongly calibrated.Download battery calibrator from market.charge to 100%,click calibrate battery..it should fix your problem

This happened to me few times. The last time I noticed was from ~48% left it overnight (only about 6 hours) and I woke up to find the phone was off. Usually my phone loose about ~25% overnight. Not sure what or who is the culprit. I have flashed few firmwares and none fixed the issue. Currently I'm rooted using Generic World firmware with locked bootloader and removed many bloatwares.

I've this program installed and I'm sure it has not helped with this issue. I see "missing data" when there is a sudden loss of battery.

I´ve also the problem; my arc is not rooted, so there is no chance to calibrate the battery...?

Had it once, took the battery out and in again and it had 20% more again. Then I charged it at home and so far it works fine.

Thank you. I´ve taken out the battery for about 15 minutes and put it in. The percentage is still as before.
Is there another way to reset the batterystats.bin without root?

Well looks like many people are having this issue, either there are a lot of faulty batteries out there, or its a problem with the firmware. I'm leaning towards the latter.
I'm using Rogers 2.3.3, what are you guys using?

I experinced this issue with Singapore generic firmware as well as World Generic (current) firmware. Hence I don't think it could be a specific firmware issue.

Awake
Anyway to find out what or which program kept the phone to stay in awake? As you can see the screenshot, the phone was awake during random times and most of the time without the screen isn't on.

Sorry, no idea,perhaps someone else here can help
For me its probably something like latitude which I set to auto update

"Latitude"? How can I verify that it doesn't affect me

Latitude comes with Google Maps, its basically a location sharing feature. If you press the menu button in google maps you can click on latitude, then menu button again -> settings, and change from 'Detect Automatically' to 'Manual'
If you don't know what it is I doubt you actually have it enabled anyway, so it could be some weather widget maybe?

I checked and my menu reads as "Join Latitude" which means I have not enabled it in the first place (I guess so).
I'm using Beautiful widget for weather service so not sure whether that is the culprit.
I wish there is more visibility for this .
Thanks for your explanations .

Btw I tried the Supercharger script, and it has doubled my battery life
(You need root)
I chose options 1,6,17

Here it happened again today early morning!!

May be due to the "Green Power" application. I checked before and if I switch on the WiFi it is continues without any problem.
I too hope for the same as you. Annoying bug .

I have the very same problem. The phone battery goes from 100% to 66-64 over the night...showing that the Cell standby and Display has drained the most of the %...

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.)

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

You are incorrect. But, in any case, I DID calibrate the battery just to cover bases in the case that I was wrong.

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.

I am asking because there may be a solution that I am unaware of that doesn't require me to put my entire life on hold for months. It is possible that there is no such solution, but I asked in case there was one.
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 G2 will shut itself off - any suggestions?

I'm looking for any ideas for the problem I'm having on my G2. I'm afraid it's a hardware problem and not much I can do about it.
I started having problems after upgrading from CM 7.1 to 7.2, but I don't think it was related to the upgrade. I started having battery draining problems, the phone took forever to get fully charged, and car mode would automatically start sometimes when plugging up or unplugging the charger. I cleaned the usb port with alcohol (with battery removed), let dry, and restarted. Now I don't have the car mode problem and the battery problem is somewhat better.
My problem now is that the phone will just die when I'm using it. Usually when I'm using the browser. I'll be scrolling on a page and the phone will just turn itself off. Like the battery died. I can turn the phone back on and it will start up, get all the way started back up, but while it is still loading the home screen widgets, it will go off again. I can repeat this several times. The only way to recover is to plug in the charger. I don't have to hit the power button again, just plugging in the charger will start up recovery mode automatically, I'll choose reboot and the phone will start normally then and stay on.
The phone never dies when I'm not using it. I'll carry it all day, making phone calls on and off, and it'll stay on with no problem. Mostly, I only have the problem when using the browser. Also had the problem while using my newsreader. Once during playing a game. But if I start up browsing the internet, it doesn't take long before it will turn itself off. A matter of a couple of minutes. I don't have the problem with reading emails with K9. Don't have a problem in downloading from the internet such as podcasts. Don't have a problem in sending text messages. Don't recall it shutting down while using the Facebook app. After putting up with this for a week, some troubleshooting and observations.
I never have this problem if the charger is plugged in. Only when it is running fully from the battery.
I've tried swapping to a different battery.
Turned down the overclocking with no difference.
I've changed to other recoveries, CM 7.2, CM 7.1, a CM 7.1 that I was running in May. No difference.
I've swapped memory cards.
I've reset battery stats.
No difference if running on wifi or just data.
Clearing caches made no difference.
So, I start thinking it must be a hardware problem, but then why does it only crop up when internet browsing. Must be power related since plugging in the charger makes it go away, but why does it not have a problem with using the phone in other ways?
Any suggestions on what I could try?

You could try to see if there is too much voltage drop when you start something power-hungry. Use a battery voltage logger and post the results. Start logging, let the phoneidle for a minute and then start browsing. Even if the phone shut off, the log should still be there after rebooting.

Thanks for the idea. I can't locate a logger that looks like it would work. It would have to capture a quick drop in voltage that is momentary. This problem happens even on a full battery and when the phone come back on (either momentarily or after a recovery reboot) the battery level is unchanged.

You might try as well an other way: first idle, then gradually step up to a more power hungry app to see when the problem actually happens. I have no other ideas...

Make sure that you dont have any contact with the battery and the door.
Normally batteries are covered with an aluminum wrap, and can cause short-cuts with the phone itself.
I searched it for a while with the galilio batteries.
You can try to put some saranhwrap around the battery.

I have the same problem with two different batteries. But I'm ready to try that too.

Battery graph
So here's a graph of my battery status. Long time to charge to 100%. Discharges pretty rapidly. Each downturn ends in the phone turning itself off. Notice that at 7:30 today, it turned itself off, I did a recovery reboot, then noticed it wasn't charging very well (green line turns to blue but doesn't increase), then I did a manual reboot and when the phone restarted, it showed the battery was at 100% charge (from about 60% before the reboot).
What do you think - hardware or software?

Well, I just took the cover off for awhile and tried it. Played crosswords (Shortz) for awhile with no problems. Started my newsreader (Newsrob) and it shut itself off in about 15 seconds. So, no short to the battery cover.

Same thing is happening to me. I use poweramp or the browser and the G2 just shuts off. Then I restart it and it tells me that the battery is low. Once I shut it down and reboot in recovery and wipe the battery cache it's back to it's normal battery level. I disabled data and set my phone for 2G networks only and it didn't shut off after. I'm assuming this is a wireless issue? I'm running mimicry 1.3.0 on my G2.

Had the same problem. Swapped out batteries and problem gone.

Did you swap the battery and immediately have no further problems? I tried swapping my battery already and still have the same problem.

Note 2 keeps shutting itself

Hello, so I have one a bit strange problem with my Galaxy Note II. The problem is that the phone shuts down by itself randomly. You can't do anything on it unless you restart it by long pressing power button or pull out the battery. The interesting part is that if I have notification I havn't checked my LED keeps blinking even in that "power off" state. So I don't think its actually shutting down. Can anyone relate and help me what is the reason my phone is doing this? I forget to mention I noticed some battery drops in the default battery monitor when this "shut downs" occur. Can it be battery related? Also I'm running stock Android 4.4.2 and no root or what so ever.

try with other battery or go to a gsm store and say "i need to buy a battery ?" if doesn't work , try to flash the rom again. or try with a multimeter a small bulb and you gone see if drops down

1st Gen Moto360 Essentially Not Working

So, I got a new phone...Galaxy S8+. After like dozens of attempts to factory reset my 360, it finally booted correctly. Now when I try syncing things, nothing happens. In the Wear App, I don't even have the option to select a watch face. After undocking the watch (which is fully charged), it just shuts off until I redock it, at which point it boots up as it was turned off. Is this thing toast, or is there a trick to this? Never had this many issues with this before.

Anyone?

Ah ? thinking you said : After undocking the watch (which is fully charged), it just shuts off until I redock it,
so when watch is not on charger it shutdown ?

You're misunderstanding my issue. Nothing is syncing to the watch, and the Wear app gives me no option to pick a watch face.

I tried resurrecting this again, but it's still having issues. Popped it on the charger, and it acted like it was going to start up, but went into a charging screen. Eventually it'll boot back up, but when I swipe down and start swiping right to get to settings to do a factory reset, it just turns off after a couple swipes. Is this thing just dead? Battery is over 60%.

Your battery is bad. It shows good battery % numbers, but it can't provide enough current to keep the watch running when off the charger.
Replace the battery and it will fix some, if not all, of your problems.
