[Q] How to fix my battery

So I am on CM 7 and I used the battery fix others are reporting single digit numbers on current widget while mine shows only two 4s in one page and others vary between 100-250 so then I head to spare parts and it shows that the culprit is Google services, Android system and Dialer... They are always the ones that is draining my battery but I dont know how to fix them help me

Have you been actually using the device a lot while the mA measures are taken? The fix effects only idle/standby consumption. Those spare parts battery stats you mentioned don't really tell that much, as the percentage there is always 100% divided amongst the processes working. Check your partial wake usage and other usage, if there is something that has been using a lot, I mean really a lot then it could be the reason. Get watchdog or similar to check if you've got apps going crazy, could be one reason.
Btw what version of the battery fix you are using, have you remembered to do the voice search, sound record etc. to activate the fix, if you are on a version that requires it?

No that is on idle. I am using the PNK ocasional build now its abt 1% per hour. Its good but it sacrifices performance now. Those 3 culprit are from partial wake usage. V7 so i need to use voice search in order to activate it?
Btw how many kernelals can we have at once?

[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

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

I chose options 1,6,17

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.)
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.

[Q] calls receiving issue

I've a serious problem in my phone that appears after upgrading to ICS, frequently when someone calls me it gives him ring and my phone do nothing and it doesn't even shows it in the missed calls, when i tested this from my other phone the phone didn't respond until i press the standby button it starts to ring!!!, this issue always happens when the phone is on standby and when i press the standby button i noticed the signal fluctuating from 0 to full like crazy and stabilizes after a second. I'd like to say that it happens frequently not every time (once or twice daily).
i had to activate the call forwarding when not answered option to my another phone until i found any fix for this issue, i was using stock ICS then used custom and rooted rom then lite kernel and nothing changes, i used CPU tuner app to set the min CPU seed at least 750 and nothing changes, changed the sim and no changes, I didn't have this issue before when using GB.
I'm currently using this phone in Egypt with Vodafone as it is unlocked
Can any one help.
Thanks in advance
Update
i had found a new app on Google play prevent the phone from going to deep sleep called (wake my android pro), it is a free app as it allow the phone to sleep and not to deep sleep so it is not consuming battery like (wake lock) app which keeps the phone running in background and reduce battery cycle for about 40%.
i had tested it for 10 days i didn't loss calls so far
still waiting for a real fix.

thank you for your reply, actually i'm searching in this issue for 2 months and i see the above links before,i was looking for a real solution not workaround as the device is already draining battery and the solution will make it worse.
i was looking for a mod or a even a rom that solves this issue because GB was working fine but its too old now.
anyway thanks again

Well, I think if there were a solution, it would be posted shortly. I am not satisfied with the wake lock too, so still at GB

[Q] Phone Repaired, What Did They Do?

My S4 mini SGH-i257M was malfunctioning so i sent it in for repair. The local Rogers store sent it to FutureTel in Markham [Toronto] Ontario Canada. This is what they did, according to the Completion Report that came back with the phone ...
;RF Calibration performed to enhance RX/TX performance and network connectivity. Passed RF compliance test to meet manufacturer specifications. Adjusted battery level to optimize power usage.
It has been two weeks now and not only has it not malfunctioned, but the battery life is significantly improved - from 2 or 3 days of light use [usually just 2] to 5 days of light use.
What did they actually do? Does the recalibration affect hardware or software? Did they perhaps re-clock the CPU down to a slower speed? Any way to check this? What do they mean by adjusted battery level?
The phone is running KitKat 4.4.2, not rooted.
Thank you,
Mick

Here are three replies from other forums to this same question. Anyone here want to include an opinion? It would be most appreciated ...
The first part (RF calibration) means they adjusted the radio to improve reception and transmission(rx/tx), so your call/network/wifi reception will be better; the battery level adjustment implies they altered the voltage to improve battery life. In both cases it's more likely they replaced faulty parts with fully functioning ones. Good to see you finally got your issue solved Mick
It seems like what they did is install the OS from factory state and give u a new battery and maybe re clocked the CPU. Unfortunately they won't give you the proper information on what they did nor will u able to find it. There are some apps which tell u what system and software it uses but that's about it
All that I can tell you is RF stands for Radio Frequency. Apparently your cellular radio was tuned a bit off from whatever frequency(ies) your carrier uses. I wonder how they calibrate this.
Their statement "Adjusted battery level to optimize power usage" makes no sense to me. It's almost an oxymoron! But then, when signal level or reception of signal is poor, firmware detects this and gives the hardware an extra kick of battery juice. So maybe that's what they adjusted?
I'm really just guessing about RF calibration and battery adjustment. Hopefully somebody more knowledgeable will shed better light, especially regarding your questions about processor speed

I also would like to know what they did with 'improving radio frequency'. Got the same problem as you, and would like to check if it's possible to manually fix the radio/frequency-problem, cause the guys from the repairshop didn't fix anything for me..
Otherwise: is there an app that notifies me when network connection is lost ?
I found this one : (updated url) https://play.google.com/store/apps/details?id=com.cnigrini.networkmonitor that works well..i now see immediately when my phone loses network connection.
However, now i still have to manually reset it by turning on/off airplane mode. Is there a way / app that does these steps automatically ?
So notifies when network dorps, and then refreshes it..
That would be one way to solve the problem i think..

Your link is to an earthquake detection app ???
I'll post more info later or tomorrow.

I updated the url. It's this app: https://play.google.com/store/apps/details?id=com.cnigrini.networkmonitor
It notifies when network is lost. However it doesn't refresh the network unfortunately.

Well, it gets worse. The phone messed up today same as before. A bit more than two weeks after the "repair". I was at home in one of the strongest signal areas. Would not receive or make calls or use mobile data. So back to the Rogers store. By the time i got there it had started working again so i could not demonstrate the problem. Also used a lot of battery power today, about 40% with light usage compared to 15% or less per day for the past two weeks.
What the counter guy at the Rogers store said is that there is nothing wrong with the phone, that all cell phones do this, and that i should adjust my expectations.
Here's another ConnectionChecker app. This one attempts to reconnect ...

Hey Mdawdy, thanks for posting that one, when reading the descripting it seems like this one is doing both things: checking when connection is down, and when it is, puts the phone on/off airplane mode so that it reconnects again.
I will be testing this one for this time now..
It's probably true that all cell phones lose connection some times, for example when being in a place where connection is very low, but the problem with this Galaxy s4 mini is that it doesn't reconnect again when in an area where signal should be good...
Probably some software thing i think..
I'm still at 4.2.2 by the way.
Edit: found out that with a non-rooted device with android 4.2 or above, it's not possible for an app to toggle airplane mode on/off. So there are probably no (non-root) apps existing that will do this .
However a forum member made a tool that does this: http://forum.xda-developers.com/xposed/modules/app-jelly-bean-4-x-airplane-mode-helper-t2385625

It's not notifing me when connection/wifi drops.. but I only see it when opening the app.
Also, like i said, i don't think there's an app that toggle's airplane mode on/off when gsm-connection is lost, because it's not possible with a non-rooted android phone that runs android 4.2 or above..
Very disapointing..
