Annoying Battery Glitch

Ever since I've been on EG22, the battery has been very annoying. What I mean by this is if I charge the phone for a few hours (and don't take it off its charger), the second I pull it from its charger, it'll say my battery is at 85% or so. What I don't understand is when I put it on its charger, it is usually at ~90% so how is the battery being drained if it's on its charger?
Another annoying occurrence was when I decided to watch netflix and I left the charger on it even though it was full (Because I didn't want to waste any necessary battery). After the video was over, I pull it from its charger and see it's at 58%!
This has never happened before, so I believe it is EG22. Anyone have this experience?
I'm running Stock Deodexed EG22 w/ root.

Just guessing. I don't think android EVER charges the battery fully...its always around 90% even if it says 100% in android. Maybe eg22 is just shown the actual percentage?

I think some people are seeing this. Did you wipe battery stats in recovery? Also, I have been using "Battery Calibration" app by Ne'Ma. You plug the phone in to charge. When it gets to 100%, you get a tone. Then you just click to wipe the stats. It has actually been working really well for me.

How many times have you done this? I usually am not comfortable calibrating my battery since it always messes up the battery readings for me. One sec I can be at 90%, the next at 92.

Well, you have to understand I am switching ROMs 2 to 3 times a day with all of the testing I do. Its actually recommended that you wipe your battery stats any time you switch to a different ROM. After that, I let it drain to about 15% and recharge to full. The battery settles after about 2 days on a new setup for me.

This is an EG22/GB bug, the phone dosnt kick back in after hitting 100% once, and since the phone dosnt go into deep sleep when plugged in (stays at 100mhz or higher) your battery will get run down if not disconnected once charged."
this is post 55 from [ERA] EPICUREAN SCrAMbLED EGgs22 v 4 w/ EG22 PLUS
p.s. the best way to see your true "battery life" is to completely power off and take the battery out for 5 mins and put it back into the phone and power it on..i know this suggestion has nothing to do with your problem but i felt i had to mention it because the phone has wrong misreads sometimes even without calibrating...I'm not on eg22 btw..or you could just calibrate and see if the issue still persists...

Lol. I am 50/50 with Urban Regeneration with White Shadow theme and SRF 1.2 with Honeycomb Fusion Explosion with animated pulldown. Both setups have transparent Facebook and G-Mail and blacked out Miren,Dolphin,Google+,Dropbox,etc...oh and transparent XDA app and paid XDA is black. Stability and everything working are my focus. I use the black and transparent apps to help with the battery because I run 1400/200 on demand, no undervolt...

Extreme Battery Level Drop After Reboot, Increases During Use

The topic pretty much explains it. I've been using different modified stock roms and now I'm on the latest nightly of CM7, and I keep having this issue. After a reboot at around 50%, the battery drops to 15%. The weird part is that while I continue to use the phone, it slowly rises back up to sometimes 30% and then starts going back down. I've always cleared battery stats when flashing and calibrated (which I believe is unnecessary), but I don't know if this is a problem with the battery, the phone, or if anyone else is having the same issue?
Attached is a screenshot of battery usage. You can see I never actually charged the phone.

anyway guys, you need to recalibrate your battery, its not being read accuracy.
download BatteryCalibration from the market, charge your phone till 100% (not just 100% but when it beeps, that its truely at 100%), then use BatteryCalibration to calibrate your battery, and then drain it to 0.. (crank full brightness, turn on LED flashlight, blast internet radio, whatever makes it drain faster to get this part overwith), then recharge it to max.
so;
charge to full 100%
while still plugged in, run BatteryCalibration
discharge to 0%
recharge to 100%
battery successfully calibrated, you will now have an accurate reading

I had exactly the same issue on 3 different custom roms....finally resolved by going bck to stock rom

Sent from my GT-I9100 using XDA App

This thing only happens on CM7 for me. It had 40% before reboot and like 15% after. However mine only increased to about 17% then started dropping as usual. This never happened on any stock ROMs I've tried(stock, not themed/modded stock).
Sent from my GT-I9100 using xda premium

did you
did you rsolve the problem ? how? I have the same problem and I tried more stock roms ... I don't know what tot do ....

Its nothing to do with calibration etc, its just how the fuel gauge chip works, it learns and more accurately reports usage over time. For example, if you reboot and (I can't remember the actual voltages for the S2) you have 1200mV, the chip goes, "ah, that is 15% battery." Then as you use it more, it relearns its settings and goes "aaah, my mistake 1200mV is really 30% battery. I'll display that instead."
Its been covered frequently that "calibrating" the battery of the S2 in any way but actually using it, is next to useless.

[Q] Miscalibrated battery, need help!

I need some suggestions on how to calibrate the battery on my n4. It got miscalibrated when I did the update 4.2 to 4.3 and I haven't been able to calibrate it since then, a week ago.
I tried using battery calibration from the store but it didn't work, I tried charging the phone from 0 to 100 and it didn't work.
I remember I had the same problem 2 years ago with my Atrix and I solved it by wiping the battery stats from recovery, but now twrp and Cwm removed this feature and I don't know how to solve my problem.
Maybe it would help flashing all back to stock with the toolkit?
If you have any suggestions I'd really appreciate it.

Just the answer I didn't expected, and frankly a pretty useless answer, everybody knows that battery calibration doesn't improve battery life.
But I have other problems, like I turn off my device at 80% and when I turn it on it's at 77%. Do you think that's normal?

Either faulty battery or do the following:
1.Completley discharge N4
2.Charge fully(+2 hours after hitting 100&) WITHOUT disconnecting from the charger.
3.Repeat for better results.

You mean off as in all the way off? If so, then that ~3% is being used when the phone boots.

I've had many phones, and none of them lost charge during the boot, at least not that many. I think that's the clear sign of battery miscalibration, I've had this problem before with another phone. Besides that, I've had a strange behaviour of the battery, for example I saw it lose 4% in 1 second, from 66 to 62 in a blink of an eye.

It's not that it's losing charge quickly, it's just the OS (or the hardware itself) doesn't always do the best job of reading it. There's not much you can do about that, and it's really not an issue unless you make it so by staring at your battery level all day.

Hi,
I'm having a similar issue. Phone rebooting to weird battery levels (not the %age it shutdown at).
Phone shutting down at 31% battery and rebooting to 0%.
I tried charging only to 100% yesterday with the phone ON.
Do I have to charge it even after it's charged to 100%?

I tried charging through the night and then discharging it completely and charging it completely again. I also tried deleting the batterystats file (even though I know it doesn't do anything)
So what do you suggest I should do? Get the phone replaced or get the battery changed?
I live in India and the phone is from Canada, so replacing the phone will take some time but I can get the battery replaced for around $20
Also my nexus is also showing +ve mA values while it's not charging, and the values are absolutely crazy, +268, +168, +1171 (in batter monitor widget)
Please tell me what I should do.

Before you replace the battery try to disconnect the battery's flex cable and reconnect it [after you charge to device to 100% and turn it off of course] check if its 'reset' the battery.

How to wipe battery stat,How to fix incorrect battery status

I have problem with battery status.I try delete file batterystats.bin in my data-system but not fix it.All version CWM not "wipe battery stats" line..Help me

Apparently wiping battery stats doesn't do anything at all, it only wipes the actual history of battery usage, the same you see when you go to the menu and click the battery.
The whole subject is really a lot of speculation that as there doesn't seem to be a definite answer to calibrating the battery.
What seems to work for me and what seems to be advised more often is to fully discharge the phone, by normal usage then leaving it charging through the night, repeat the process the next day. When doing this process don't charge it in the middle of battery, you must wait until it dies.

@Mottz is right. Wiping that file only removes the history of what app used how many percent of the battery. This has been confirmed by a Google engineer.

[Q] Fault battery indicator [SOLVED]

Hello, :fingers-crossed:
i'm having a lot of troubles with the battery of my Nexus 4. I'll try to explain this strange situation...
Few days ago i noticed a ridicoulous battery drain while i was, as usually, listening to some music with my bluetooth A2DP headset Jabra HALO2. It was something like 1% every less then 1 minute. At first i thought it was due to a recently upgrade to CM10.2M1 (which is a monthly build of Cyanogenmod on 4.3) or due to a 5 minutes fast charge from the 2A charger of Nexus 10 that could have "upset" the battery.
At first i started focusing on the software side problem; i tried CM10.2RC1, CM10.2, stock 4.3, stock 4.4 and now CM11M1, and, while doing all of those wipes, i noticed that not only the discharge was insanely fast, but even the charge! The graph on the setting panel is almost vertical while cahrging, like 3% to 40% in 25 minutes.
But that's not all, sometimes, after rebooting, i noticed a battery level different from the previous boot, so i decided to wait a full discharge and then fully recharge it. I have waited the 0% (not so much time ) putting the screen always on and the LED flash too, then, i tried few times to turn it on and every time, after the boot screen disappeared it immediately started to turning off due to 0% battery.
Moreover, for being certain, i tried to turn it on in recovery and wait how much time it would take to consume the lasting charge on the battery. Surprisingly, after 30 minutes it was still there! I tried a reboot into system, showing me a 10% remaining battery (WTF), which discharged to 0% in like 3 minutes. Now i'm waiting the whole night the real discharge in recovery with screen always on, hoping that a full recharge could fix it. I would like to evidence that the phone do not overheat during both charghe and discharge, so i guess the battery itself may be ok.
I'm still not sure if it's a software problem, and i'm worrid if it could be an hardware related issue. Maybe it could have been the charge from the 2A adapter.
I really don't know what to do next. Someone knows how to help me?

EDIT:
I've done a full discharge until even the full hybernation has been shutted down, but seems that it hasn't solved anything. I've also noticed that in the battery stat is missing the display consumption (WTF?!?). Maybe it's a CM11M1 bug, it happen even to my Nexus 10. Here other shots:

EDIT:
I've noticed just now that while I was waiting a real full discharge of the battery the TWRP couldn't show me the battery percentage. Really strange...
[SOLVED]
In summary, the problem was the combination of kernel+ROM. The CM with his kernel on N4 was consuming tons of electrons. I tried Purity+Hellscore, now i reach few days of low usage and one and half of medium usage

It have 9 months, and yes is still under warrenty, but I've bought it in Spain, and I live in Italy. I think this will be hard to solve

I have some strange problemi too.
Sometines the phone reboot itself and the battery drops (i tried to flash all stock: recovery, bootloader,ROM ecc..)

It could be a faulty battery.. Read this topic, it looks like you have the same kind of problems.
Do you also have simlocks/loss of network connection?

I've already read this topic, i think the source of the problem may be related with mine, but symptoms are different. It is strange that this happened 9 months later!

Gully discharging the phone, rebooting, discharge again if any, reboot. Connect charger, charge full. Reboot, charge full again if any, reboot. This always worked for me.
You can also try to fully discharge, completely power off the phone and let it fully charge while powered off ( only a white battery should be shown on the display).
