Hello People,
First of all I would like to thank all the people who have contributed to this forum
I found each and everything very usefull and informative.
I've O2 Xda mini with OM version1.13.00WWE Radio1.12.00 protocol1337.42 with bigstream.
Lately my backup battery shows low and hwen i check the battery meter it shows back up battery NONE
Sometimes it automaticallu comes 100%
I dont understand what is this...
Can someone help me with this??
Do you frequently remove the main battery? If not, most likely a software error. Try doing a soft reset.
Yes previously i used to swap a lot my sim cards but now i dont remove battery quite often
These days sometimes it says back up battery low abd charge as per user manual
Like today i did full charge back up was 100% and suddenly it said back up battery low?
Hello,
I'm a first time poster looking for a little help. I've had my Verizon SIII for about a week now and almost everything about the phone I have loved with the exception of the battery life. Given the 2100mah battery I was expecting much more. I tend to be a fairly light user throughout the day at work, I have the screen brightness turned down, all data is off, and I really only am using it for texting, maybe a little bit of gaming. I have found that if I unplug at about 8am by about 6 or 7pm the battery will be nearly completely drained.
Noticing that this seemed to be a fairly common problem I started doing some research to determine the source of this. First, by looking at the battery stats I observed the same problem that many others observe, a heavy drain in standby mode.

So going off of this I started trying to determine the cause of this drain in standby mode. I should also mention that at times the phone does seem to get warm in the bottom left region of the back of the phone. I had read one tutorial explaining about wakelocks so I decided to check that out. I downloaded GSam Battery and CPU Spy to see if something was preventing my phone from entering standby mode properly. However my phone was entering deep sleep as shown below, so this confused me a bit. But clearly there is some issue visible in the standby mode of my phone, sometimes the battery will drain ridiculously fast (as high as 1% every 5 - 10 minutes). And keep in mind that this is while virtually everything, data included, is disabled. So that eliminates the possibility of it simply having to search for a signal in a weak area.

Basically I'm having a tough time getting to the root cause of this problem. I feel like there's some little software issue in there that is draining it. But I've been pretty smart about the apps that I've downloaded, I've stuck with only very common and popular ones. So would anybody have any clue to how I could identify and address the source of my battery drain?
Thanks

You don't have to thank me there is a button for that
Download and try Watchdog Lite. It's a really good monitor for finding out which apps are acting up.
This doesn't exactly answer your question, but can help with your problem. There are programs that can help to drastically improve battery life by turning off data (3g\4g) while the screen is off. This can double your battery life or more, especially for lite/moderate users. Most of these programs work by turning on the data 1 minute out of every 15 the screen is off. That way you still get email, and notifications. You still get txt and phone real time, as they do not rely on data. When you turn the screen on data is turned on, when you actually would want to use it. Especially in 4g areas this really saves battery, as 4g is a battery hog.
Battery Defender is my favorite. I feel like I should be paid for this advertisement...
Do you have BATTERY SAVER option ENABLED in settings? That makes a huge difference for me.
It sounds like you are still stock, but I used the Root66 image and after that started having huge battery drain. I did a factory reset to no avail, so then moved to Synergy Rom. Since then, I've had outstanding battery life! not sure if you were thinking about going this route, but it has worked for me. Synergy is debloated so I assumed Verizon crap to be the culprit.
The images I saw were all at 100% battery. Those are not very helpful. A shot of your battery stats at the end of the day would be a lot more useful.
Please note that Cell Standby reports incorrectly at the moment on the S3. Unless you do the fix linked above, it will nearly always be at the top, but it does not actually drain that much battery, it is simply a reporting issue.
Hello, i'm a newbie to xda developers... I had some problems with my Sensation... I am really a newb to those stuff since i never rooted a phone... The problem with my phone is that the battery doesn't slowly drain... I let it to charge for like 5 hours to get to full 100% and then from 100% it goes to 60% in like 10-20 minutes while i use it ... Other times the battery shows to have more power and other times it straightly goes to 40% from 100%... It drains so quickly i can't even go outside with my phone since its battery gets empty... Sometimes, even if the phone is 60% it randomly shuts down and have to restart it for like 5 times to get it work for at least 10 minutes. Might it be the battery? I tried going to recovery mode but i get the red triangle with an exclamation sign in it... Any reply is appreciated, thanks!
Maybe your battery is rubbish and you should just buy another one.
Although is one thing you should try first, recalibrate your battery.
What all these methods amount to is how to teach your phone about battery performance. Calibration is about enabling your phone to provide accurate estimates of remaining battery charge and will not, in and of itself extend the usage you get on a single charge (though it may possibly prevent the phone going into power save modes prematurely, wrongly believing the battery to be lower on power than it is).
The phone stores information about the battery in a file called batterystats.bin which sits in /data/system. Normally you won't have direct access to that file, but you could find it with an app such as root explorer, which allows complete access to the phone's file system.
When you install a new ROM, or a new battery, or perhaps periodically as the battery ages and performs differently, you need to get a new set of battery performance statistics.
By charging the phone to 100% you are starting at the known maximum for the battery. At this point, the batterystats.bin file needs to be deleted, which forces the phone to recreate the file from scratch, using the information it is about to collect. It doesn't matter what method you use, battery calibration app, or from within recovery - they all do the same thing and delete this file.
The phone is then allowed to drain fully. This gives the other end of the scale, the known minimum. The phone then has then experienced the full charge/discharge cycle of the battery and stored that performance information in a new version of the batterystats.bin file.
Now that the information has been saved, the phone will (hopefully) be able to provide accurate estimates of the battery charge level, regardless of how much of the battery charge you use before reconnecting the charger.
If you don't have root access you can download an app from the market called "Battery Calibration". It does the same thing, deletes the batterystats.bin.

Thank you for your time. You explained really well and i appreciate that... So, to use the calibration apps i need to have root access... should i search a tutorial on that or is there one on the forums? If the calibration can't fix it, should i get another battery? Thank you again! Maybe i should try to buy a new battery first... is rooting safe? can i get back to my old firmware?

Well, yes I guess you should root your phone first, but I'm not sure
A guide on how to root your Sensation can be found here .You should only do the steps 1-3.
If you don't want to root there is another method somebody wrote (I haven't tested it personally)
1. Turn off your phone.
2. Fully Charge.
3. When getting 100% signal, unplug quickly.
4. Pull off the battery and put it anywhere.
5. Wait for 180 seconds minimum
6. Put back the battery on the right side.
7. Turn on the phone.
Than you should be OK:good:
If you get the same result after "battery calibration" I suggest you buy another battery.
Hit THANKS if I helped you
Hello, i have two more question related to this thread... Is there a way to calibrate my battery without root access? And will buying a new battery surely fix my problem? Thanks again!
You might be able to get a calibration application in the playstore. However most I've seen require root access. But look, they're might be some without root requirement. As for your second question. Nothing is ever 100% guarantee that it will solve the issue. These are suggestions based on the information you provided regarding your issue . How can anyone be 100% certain that will solve your issue. It's defiantly a possibility it will solve the problem but no, for 100% certainty, I don't think anyone can say that. It's defiantly worth a try ! Then you can see if getting the battery solved the problem. I hope it does fix your issue and wish you the best .like I said, no one can be 100% sure but it's defiantly worth trying!Sent from my HTC Sensation 4G using xda premium
Everything said in this topic is PURE NONSENSE. It was even featured on the front page that wiping the battery stats DOES NOT DO ANYTHING. See this article for more information > http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/
The only thing you CAN do is charge your battery to 100%, and let it drain to 0%.
Aparently, after i cleaned my battery contacts it DOESNT jump to random values... drains continously.. SO i think the problem is fixed... atleast for a while! I'm new using a smartphone and the battery is a little 2 weak as i was used to my other non-smartphones... I think that's the battery life a 1520AMH can offer me on a sensation! The uptime for it was 6 hours from 100%... thats really weak ( i used the web and games).
Greetings;
Im having a weird issue (again - but with different device now).
After re-flashing about 4 or 5 times my p3110 with stock firmware (i never used customs) my battery wont charge to 100% anymore... It will reach 99% and wont reach 100%.
This happened to me previously with i9003.
Actually with i9003 everytime i flashed my device the battery would show a lower value each time.
Also; with i9003 i used Custom Roms; and used to " Erase Battery Stats "; wich such erase seemed to be the problem.
Since i've never erased my stats (to keep my device as close to factory as possible); what could be causing this issue?
Any experts on this matter that can provide me accurate info?
Thanks in advance.
Best Regards;
Richard

The first thing that must be checked here is that wall charger and usb cables are not at fault. It maybe a coincidence that happened at the same time you started flashing stock firmware.
2nd depends on the firmware which you have chosen,
Different firmwares have different ways of working. Some have blocking modes, some have power saving modes, different set of features, different bugs as well too.
It might be a glitch altogether as well.
Nobody can explain this exactly accurate unless you try these options. Mine aee just aimed at pointing you to the right direction.

One more point, tried discharging it completely? Then charging it in offline/online mode?
Now what about battery stats?
Erasing battery stats, well if you have searched on google about it, you would have seen mixed comments about it's affecting battery life, some says it does help, some says it doesn't.
Some feels It's better to do it and
some prefer better to leave it untouched.
My experience on same issue
I had 2 same sduos devices.
on both I used to flash roms
Custom, stock, everything.
Only difference was, on first one, I did erase battery stats many times.
And the second one I didn't ever touched it.
Result-well the first one, I got 4 other batteries replaced for it, and even the new ones would have trouble keeping the charge on the device after I wiped the battery stats. I couldn't blame the battery stockist for giving me 4 faulty batteries. Battery levels were erratic on stock, on custom.
Second one seems working pretty much nicely and i still haven't replaced the original one. Although on this, sometimes I have a glitch, where battery level would drastically go down after restarting the device and slowly build up to the same level without charging.
I know it's a glitch coming from the custom kernel side. Altogether it's better this way.
Greetings Billysam;
Thanks for your repply.
I aleady had checked both (Charger and Cables) they seem to be just fine.
Yesterday i decided to give my p3110 a good rest while charging and finally it charged completely.
Seems like the last 1% (to achieve full battery charge) requires a little bit more time than usual.
It may have been something related to the last flash i've done or due to constant use.
Stil... It is hard to point out what has really happened.
I was a little bit affraid that my battery or System got messed up somehow.
Do you know if flashing affects the Battery Stats in any way?

The last one percent does take extra time to reach that last 100% charged level.
The answer to your question is Yes and no.
Where is batterystats stored? It's stored inside root/data/system folder
When you flash or format your device data, it gets wiped too as well
So, Yes. cause it got deleted even when you only deleted data.
It affect battery No. Why?
What information that file has? Is it really important?
Information that you see in settings battery
It holds record of all the past history not the current ones. Or future ones.
Now you decide.
Greetings;
Superb Answer!
Exactly the answer i required.
That gives me whole new perspective, and confirms my theory regarding past and new files when flashing.

Further additional bummers
I was checking the batterystat in my device, and to my findings i saw, the file got modified after I full charged the device. So, it gets rewritten/modified/deleted after each full cycle. So, regardless of flashing rom or data, that file is constantly deleted, modified and created!!
Now suppose if I decide to delete that file holding my current charge capacity information, or the better so called "battery calibration" or "wipe battery stats" from cwm, which is nothing more than deleting it the same way from a root manager.
The file would be created again after restart, with new stats, which could be random or the lowest or highest values, according to the algorithm. Which would be seriously clueless of what the heck did happened to it!
That should clear why people claimed to have good and bad experience with their battery stats.
Even if their battery were good, the stats showed it bad and vice versa.
The algorithm is not at all easy to crack, let alone be calibrated. Even If someone would try to do it, Highly impractical, nor worth it. False claims.
Easiest was deleting it, thinking of it as a refresh, users would do it. And termed the coin calibrated.
"Got better", worked!!
No? Keep Wipe again and again.
So many apps were popular for calibration as well that time. Around 4 years back. I Can't remember their names but i did tried them as well!, in the beginning!!
I did learn from my mistake over the years, thanks to you I looked for answer inside me today. Although I stopped that habbit long ago, but you reminded me of digging deeper today
It should never be done.
Greetings Billysam;
Thank God i'm not the only one reaching such conclusion.
I've done pretty much the same steps; except i didn't knew what to check within the "battery stats" file, and i wasn't aware of the algorythm behind it.
I've tested pretty much those applications as well by that time with my i9003. (Back then someone said iDeleting Battery Stats / Calibrating had a "bogus" effect...)
Well.. I did noticed lots of differences each time i Deleted the " Battery Stats " - Either with CWM or through some application.
Sometimes Good improvement, sometimes terrible (until battery got fat, and stopped charging completely - Actually my i9003 is stuck at 60 or 80%, it simply wont go further).
After so many "Mistakes" on my i9003 i realized that the Battery Stats should be left untouched to prevent any " damage " / issues. I just didn't had a clue what exactly was behind that " Battery Stats " file ( Changes and Operations - or Code if you Prefer)
...
With all this being said and tested.
It seems Logical that Whenever we put a device charging, it should charge completely without interruptions.. Else it may or may not corrupt the file, algorythm or make the battery faulty.
Maybe these are the reasons why manufacturers advice people to fully charge their devices, and in some devices to "Not Fully Discharge " them.
Ofcourse, this is just a theory.
Hi
All of a sudden my battery started draining rapidly. See the attached screenshots for ref. I thought maybe it was a software bug since it started happening 2 days ago. I tried booting into the safe mode and the fast drain didn't stop. I also did hard reset with same result. At this point I'm thinking about getting new battery. Just wanna see if xda community has any tips if maybe I've missed something. It's just strange that this sudden degradation happened overnight.
Obviously, that draining is not normal.
In the upper left corner there is a warning that some app is running in background.
When you did the hard reset also you did a restore from some backup? Is the device warm/hot?
Sometimes it shows carrier utility or people apps running in the background. I restored from Google backup (forgot to mention in the OP). Device isn't hot at all.
i stared clean with LeeDroid ROM (had original Sprint ROM on) after wiping the data and the fast battery drain remains. at this point i'm going to replace the batter since it's not a software issue.
I'd definitely say your battery has shat itself. I'd also try something like gsam or battery info in *#*#4636#*#* to see the health of your battery. I'd be interested to know if it reports it as "good" health
It's strange but the standby seems to be better now whereas it was going fast before. Thought maybe it 'fixed' itself, however during a phone call (4min) I lost %3. That's definitely not normal 4636 is not showing any battery info. Can't find anything in gsam showing health status of the battery. Is it in pro?
If the battery drains fast during calls can be due to poor/weak network reception (the modem tries to maintain the best quality and scans the network over and over).
3 sot with 50% (or little more) battery left is a good value, in my opinion.
Oh, when recoveries are made due to some problem is better to not restore from backups. In that backup can be the app or setting that is causing the problem.
Anyway, with the last google play services (14.7.99) I also have noticed a bit more drain during standby.
Sounds like you need to replace it

I have about the same issue. The battery is draining too fast and it's very noticeable when idle, even when idle in safe mode + airplane mode it loose 20% during an 7 to 8h night. I tried all htc nougat and oreo official and unofficial roms and nothing fixed the problem.
I also used the htc diagnostic tool to determine whether my battery is "good" or not and..... according to the diagnostic tool it is "good". Notice that according to diagnostic tool the battery is defective only if it goes from 100 to less than 75% during the test. Mine goes from 100 to 93 during the test which consists in showing a kind of dark grey screen at full brightness during 1 hour.
Even with a battery rated as good I decided to sent my device for repair because it was not good.
I received the device back and it has not been repaired because it passes the diagnosric tool test. test.
So i'll replace the battery myself as soon as i'll receive my new battery.
I suggest you to run the diagnostic tool test and if you get a decrease from 100 to less than 75, they should repair it under warranty, if not, suggest you to replace the battery yourself or pay somebody to do it for you.

I already ordered the battery and will do the replacement myself if the wait times are similar to those of screen replacements. Plus everything points to a bad battery so another test with official app is pointless. Sounds like we both will be doing the swap ourselves.
So I put new battery in and the drain seems slower than before and the charging is not erratic (jumping). When I was removing back cover the black layer came off so I figured it'd be good time to try clear cover mod . I like the look but unsure if anything will interfere with the radios and such due to the missing protection.
