I am facing a peculiar problem since last few months.
On every Restart of the phone, the battery goes down by atleast 8-10% sometimes as much as by 15-20%. But this is not real drainage as on the reduced percentage the phone stays for long as it would have taken to drain in real usage.
I can't recollect from exactly when this happened but its not less than four five months. In the meantime I have changed many ROMs, calibrated battery with "Battery Calibrator" many a times, deleted batterystats from CWM when the position seemed to improve a bit. But after two or three restarts the same problem comes back. I am now on Mini CM7 ROM latest version by nAa.
I think its a calibration problem or is it time to change the battery?
Any similar eperience / opinion on this / help to rectify this. BTW I searched / googled for this topic but not found any. In fact I found a thread in some other forum for some other device where battery increases by 10% on every restart (Great thing is't it?)
Expecting some positive reply

Try to clean battery history (xRecovery/CWM -> Advanced Settings -> Clean Batery History) or use Battery Calibrator, found for free on market. The app has the instructions.
Either that or you could use a root explorer to delete the batterystats.bin file in data - system
Try to fully charge the phone first though then delete the batterystats file then unplug and let the phone fully discharge the battery, this should totally refresh the battery statistics that the phone reads

Thanks to both of you . I have tried similar solution. Still then I will try them again.
ok i have a x10 mini with mini cm 2.2.1 and nAa v14 kernel
if i restart i gain 10-15% more battery
it seems that if i charge it from usb i get better readings but if i use the house charger ( a iphone charger ) it charges quicker but battery stats are way off
did everything wipe battery stats , delete batterystats.bin , charge on or off etc
Hi all,
I've got my sg2 since june and since the first moment I have got the same problems. I had the stock ROM & kernel with android 2.3.3. The problems I experienced were these:
1) extreme low battery life (6-10 hours, with normal usage)
2) when using heavy apps, my s2 just suddenly turns of. When rebooting it, it has a battery drop of like ~15%. (this only occurs when battery is already bellow 40% left).
3) Like 5-20 times a day (it really difference day-to-day), I got the notification that I have to put my sg2 on a charger. - So the battery bar drops from example 80% to 1%. After like 1 or 2 minutes it just fills up back again to the 80% before. Sometimes when this occurs, it also turns in a few % (like 80% before, and afterwards 75%).
So what did I already tried to fix this?:
- bought new 1600mah battery > didnt solve the problem, conclusion: no hardware malfunction
- I thought the problems could be occured by the tiny space between the battery and the frame of the phone. So it had a lack in connection... So I filled up the little space with i tiny piece of paper> nope didnt helped.
- downloaded mutiply apps for battery saving, task killers, etc etc.> didnt help!
It's really really frustrating, and I'm guessing more and more it's just a software problem. I do have warranty/insurance on it, but i don't want to send my phone to a repairservice because then I've no phone for like 3 or 4 weeks.
So my last option for me was to try a custom ROM and Kernel. So last week I installed the Lite'ning ROM. I also followed up the advice to calibrate my battery, so i did.
And the first day it was running really smoothed! At the end of the day my battery was still alive and I've used it for over 20hours, so I was really statisfied... But a small sidenote: I had a really busy day at work, so I didnt use my phone that much.
So next day, used it alot more. After 5 hours it had only 50% left.... And that's not all, my phone turned off suddenly. Not once, not twice, but 5 times that day.
Seems all these solutions didnt help. The only positive thing of installing Lite'ning ROM is that i now have about 4 or 5 hours more battery life a day.. But if I use it alot, it shut downs a lot more. Wich lead in more battery drops after reboot.
I'm really desperate, and I really don't know what to do now. Does someone have got these really frustrating problems, and do you guys have got some solutions?
And one more question: is my warranty/issurance voided after installing the Lite'ning 6.1 ROM? or can it by tresspassed by using a Jig?
Tnx for your time, and I really really hope you guys can help me cause i'm really getting sick of all this. It's killing me!!!
ps. sorry for my bad english
your warranty is voided by installing custom rom but u can unroot and use the jig to remove counts in counter.
now apart from that it seems if u use your phone for 5-6 hours continuous it will drain the battery because main source of battery drain is the screen display but for moderate use it should be a little over a day.
i am unclear about your usage but still if you have doubts you should really get it checked at a service center.
I would flash back to stock, use the jig to clear the flash counter and exchange that phone, seems it has some type of hardware issue that could be related to temperature as it only shuts down when you use it.
My 0.02 cents

My usage is definetly not THAT extreme, i guess moderate: I never watch movies or youtube, just some messages with WhatsApp, about 4 of 5 times a day checking Facebook, same for Twitter, always GPS off, some time of the day Wi-fi on, never play games, always closing apps on background.
i've got an example of my battery usage (this is one of the best battery usage days i got!!!):

Today step 2) happened to me
Hi guys, this is not an usual battery drain problem. I am more or less an advanced user of android but I´m writing here because I tried all my ideas and none of then worked.
I have 2 Neo V, stock. One day one of them started to have battery drain. Im talking about 6-7%/hour with no usage, the other one is around 1-2%. So with any use my phone don´t last more than 14h.
I started to check the usual(wifi policy, services running..), and don´t found anything, I switched the batteries between both to see if that was the problem but drain was still in the same phone.
I rooted the phone, tried BetterBatteryStats and CPUspy and all is OK, most of the time DeepSleeep etc.
After all I unlocked the bootloader with the S1tool testpoint etc and flashed some Cyanogen 9 rom + kernel, and the problem still persists.
I think there is nothing I can do and my phone is useless because I suppose I don't have warranty anymore.
Any ideas about what could be? Even if its hardware, what kind of hardware problem can make this high battery drain if the CPU is not working ?
Thx in advance
edit: In HTC we can also flash different RIL´s (radio interface layer) to improve signal db, avoid high battery consumes etc. There is something similar in NEO V? Because I didn´t find anything.
There are a couple things you can do:
1) Did you check that you had mobile signal all the time??, because losing mobile signal is THE biggest battery drain possible
2) Post some BetterBatteryStats screenshots so we can see what's happening under the hood
3) Try a different ROM/Kernel combination, that sometimes helps
And no, there's no RIL flashing here, just different ROMs/Kernel/Baseband combinations
I HAD the same problem
Even I faced a similar problem on my Neo V after getting FXP CM9. FXP 122 was fine. But FXP 123 and 124 drained the battery very badly(No considerable Deep Sleep in CM 9). So I switched to AOSP Polish blood. Battery life was excellent but it lacked customization, so I switched to AOKP v38+ AOSP kernel. Superb ROM but again not so good on battery (but better than CM 9). Yesterday I flashed the FXP 125 kernel. More than 5-6 hrs of WiFi, 15-20 calls and texting and some instagram and I still have 20%. I'm charging my phone now!!
I´ve uploaded some screens of bbs, cpuspy and batterydrain with wifi on and after switching it off.
Hope it reveals something, what really annoy me is the deep sleep activated most of the time, so I don´t really know what to search.
Just as I thought, what's happening to you is what happened to me a year ago and I thought changing phones would help.
Your problem is basically, bad signal, as you can see in screens 4,5 and 7,8 "No Data Connection" and "No or Unknown Signal" are preventing your phone from going into Deep Sleep, the problem comes from bad 3G signal (or just bad network signal if you don't have 3G) and that is known to basically eat up all your battery.
How is the network signal where you are???, because it looks like it's realllllyyyyy bad.

Are you sure? Take a better look.
Or at least deep sleep graph. And those graphs "No Data Connection" and "No or Unknown Signal", are also ok(ven though the name is confusing a bit), I have the same.
I'm not COMPLETELY sure but this is exactly what happened to me a year ago with a Samsung Galaxy Mini, also if you look at graphs 4 and 7 Deep Sleep doesn't have as much time as the data and signal bars, to me that seems like those two are keeping the phone in wakelock state more than it is spending on Deep Sleep.
I´ve been experiencing this problem for weeks. About signal I tried everything because:
- Phone worked perfect with SIM and all bars (I live in the downtown of a big city)
- When the problem started to happen I switched to another phone and this one was working without SIMcard so there was no signal at all.
- Some days ago I used another SIM which also have all bars.
I Don´t think there is a problem of the signal . Also in my other phone, and as you can see, Deep sleep is working fine.
I reread your first post and the only hardware problem that I could think of is a faulty battery, did you use to leave it charging all night??, because that tends to burn the battery and it does hold a lot less charge.
According to what I've read, everything seems to be fine software side, my only idea would be that you reflashed stock ROM and check if the problem persists, reflash but don't restore any data, the problem could be a misbehaving app.
I have 2 Neo V (my father´s and mine) I switched batteries, and the problem persist in the same telephone. Also both of them have less than 2 months, so batteries are new.
Also revised the voltage in the CPU and it is alright.
Well, the only thing left to check (IMHO) is a misbehaving app or service, maybe check for task killers or battery savers in the "broken" phone, those are known to eat up the battery like it's ice cream!!
I believe I have the same problem. I can't remeber when it started since I tried lots of roms,
but I flashed latest ICS from pccompanion with no other tweaks for some days and it
continued the same.
I also thought about bad signal, but at night in flight mode it also spent 40% of the battery.
With a good kernel, undervolting, 2G... I can get to 15% 20% at night.
I've also switched batteries with other neo's and no difference.
Phone is 5 months old.
Not sure if it might come from the rooting process. If I understand right, the 0% issue
that some were having was more of hardware issue (or I'm completely wrong?) Then maybe
there is also something related?

0% was a software related error (flashing GB 2.3.3 after having 2.3.4 broke the battery gauge firmware), however that problem doesn't exist on ICS, I find it reallt strange that both your phones have that problem, I've had my Neo for 8 months and the most battery I've lost overnight has been 10% (with CM9 and really bad signal).
Maybe the best thing you guys can do is send your phone to service.
I have a similar problem with my mt15:
when I buy my phone battery was ok. about two days with intensive social use, no gaming.
5 months later, battery drain begins: deep sleep and 8% per hour , airplane mode 8% per hour
tried almost every popular rom in development forum ICS stock, codename, tweaked, cm7.2, cm9, jjhybrid, KA, ...
tried every popular kernel: stock gb, stock ics, alliance, suave, super, nightelf, cm kernels...
battery drain happens while phone ON, happens with airplane mode, AND happens with PHONE TURNED OFF.
I thinked about battery fault. replaced my battery with a new genuine one. Same results.
If I remove the battery from phone, IT does not drain. 24h later battery is still 100%
So my neo has a hardware problem I think. And there are many people with same problem. look for "neo battery drain while off"
Neo is a buggy phone. you can be lucky, or not. but many people has these issues or 0%batt.
I give up!
After sony abandoned x10 mini pro (random reboots, eclair), I had given another chance to sony with neo. I like sony designs, but Im really tired.
sorry about my creepy english
Try freezing "Calendar" with Titanium Backup and see if battery lasts longer. It helped for me.

about battery drain when phone is off
its not consuming your battery while its off
when you are turning the phone on
cpu usage will be on 100% to run all necessary sevices and apps and most use goes to get signal
that's normal
i suppose its aroumd 3-5% of battery consume
im not gonna be at the same side with you
actually neo is a wonderful phone
i beated the score of sensation xe in antutu benchmark with it
just google it around the internet
there will be some fix mate..
Neo is not buggy at all maybe yours but not mine
this might work for you
i just found it
1-flash build 42 official rom on your device
2-root the rom (there are plenty of ways around internet)
3-flash this kernel via flashtool forum.xda-developers.com/attachment.php?attachmentid=780407&d=1321113977
4-now turn on the phone its gonna show 85% of battery
5-install this forum.xda-developers.com/attachment.php?attachmentid=897721&d=1329003275
6-plug the charger into your phone
7-from the menu of app select start full charge
its gonna take 3-3:30 to be full
may be you've seen it around web
i translated it from a persian forum
HIT THANKS IF I HELPED YOU
In my opinion, a phone broken by a software update/downgrade is buggy.
About battery draining while off, not all neo have this issue, but mine is not the only one.
On the other hand, about power consumption while booting, if i remove battery while off, wait some hours, and replace, after boot battery is 100%
Sent from my JJ's Hybrid MT15i
I had this problem too, even when the mobile was off, the battery was drained...
I sent my phone to after sales service and now it's normal drain 2 - 3% per hour when idle. (I was on stock rom and kernel, never changed).
There is maybe a bad hardware series
Hi there folks, yes i'm noob, i tried to search for a similar situation but i would apreciate another opinion since i'm observing my phone and i can't understand at all. Everything started when i was on 4.0.3 stock branded and my batteriy suffered of instant drain, random reebot and stuff, i decided to move to Cyano9 but the situation was the same and so here i am on a 4.0.3 stock italian after a deep clean. The problems persist and it's get annoying. i noticed that the phone shut down mostly when i'm using it (browsing internet, downloading stuff..), in the last few hours twice while downloading from play store, and once when playing a game, and after the shut down i have problems in restarting it; when i manage to power on (sometimes recharger is needed) the battery ha 30/40/50% lower charge. First I think it was a rom problem (cyano9), but now problems won't end, the fact that the phone reboot when i'm using it does indicate that there is still a software problem or maybe it's just the battery that can't handle anymore? i have this phone since last year and previously I've noticed a general lower charge. I hope it's not an "internal" problem, i can buy another battery, but not another phone! I've tried to recalibrate several times, two or tree time waiting for total loss of percentage and recharging it for 4 hours, using recalibration tool from Google play, as i recall a wipe battery... from clockwork, but now my cell is not rooted.

Hi
I searched the web and also on Xda but I could not find an answer to the problem I got. I want to know if anybody has the same problem as I have. Firstly I want to clarify that I am NOT talking about a normal battery drainage caused by background apps, foreground apps, enabled wifi, bluetooth, google background activities, synchronisation, facebook, google location settings, any antivirus app or something of that kind. There are plenty of threads about that and google search is full of this topic. I am talking about something else when it comes to sudden and quick battery drainage.
It already happened to me a couple of times when I use the built in projector of my phone (samsung galaxy beam). So I watch a movie on the projector and it takes let say.. around 30 percent of my battery life. After I turn the projector off, close all foreground and background activities I wait like a minute or 2 and the battery status drops from lets say 28 to 20. This is normal as the battery status somehow needs some time to get "updated". So after every single fore- and background activity is closed and I got 20% battery left I go to bed. Then in the morning I look at my phone and its dead meaning the battery dropped to 0 causing the phone to turn off. And thats not normal for me. (I do hear the sound of very low battery in the early morning meaning it doesnt turn off within 1 hour which would mean faulty battery) First I was thinking that this problem might be caused by previously overheating the battery but I checked the temperature and here all is fine. Also both batteries are not too old and still work normally (beside the described problem). I may add that using the projector itself is not an "extreme" usage of the battery. When I use the projector, play an HD android game connected to my ps3 controller ...that is a different story.
So my question is what could cause this rapid battery percentage drop even tho the phone has no activity at all and sleeps. Sometimes it happens and sometimes it does not tho..If I would not use the projector then I loose around 2-3 percent overnight, if I use it then I sometimes loose 20% without doing anything. And thats not normal. I understand that a lot of people dont have my phone, but I still would like to know if anybody had the same issue on his phone after "heavy" usage? Maybe android somehow thinks that there is still activity even tho there isn´t. Like a virtual activity making the battery think its in use and therefore draining it. Any thoughts on that?
Im running on 4.1.2 JB stock rooted

I wrote that already in the post. Its the Samsung Galaxy Beam.
ya, even my xperia m with JB 4.3 drains heavily.
This is a case where actual current measurements will narrow things down.
It could be that when you turn off the projector, there is still some hardware drain going on.
It could also be that the last "20%" of your battery is really only 1%.
For current measurement, see: http://forum.xda-developers.com/showthread.php?t=2487055
this can be due to some defect with ur battery or with the charger that you are using, you can rule this out may be by trying different charger and also changing the battery to rule out the battery defect. what @Renate NST say could also be the issue.
Problem solved
Ok. Just a little heads up. I managed to solve the problem. Thanks for the replies. This is how I solved it:
1. I first ran this app ( Battery Life Repair) to check for any faults in the battery itself https://play.google.com/store/apps/details?id=com.BoshBashStudios.batterydoctorrepair
2. Then I installed this app (BatteryCalibration): https://play.google.com/store/apps/details?id=com.nema.batterycalibration and followed the advise as written on the app (regarding full charge and discharge- I discharged it until the phone switched off). Find the XDA thread of this app here: http://forum.xda-developers.com/showthread.php?t=1024867
3. After I watched a movie on the phones projector I restarted the phone and it stopped from draining the battery until 0 and went back to a normal discharging state
So with a bit of heavier battery usage (watching a movie on the projector) the phone or battery somehow memorized this usage, and thought it has to continue in this state even after I ended the movie and turned the projector off. But the above 3 actions solved my problem. Its important to mention that you will still loose some battery life as you need to restart the phone. But this is obviously way better than having the battery run down to 0% for a virtual usage... :good:
PS: If you still got problems with ur battery you might want to replace it or change your charger...
