Hi,
KatKiss KitKat v33 user. Loving the ROM. But recently my dock battery is going from 100% down to 0% in just minutes of use and from 0% to 100% charged in just minutes too. It previously worked great. Tablet and dock are about 3 years old. I've stayed away from depleting the batteries. I've tried flashing (wiping too) the ROM again without resolving the issue. I'm currently trying a trickle charge but don't expect success there either.
Am I missing something obvious or is this just your typical dead battery?
Sounds like end of the batteries life if you've 100% wiped and re-flashed everything
Can't remember off hand but I feel as if there is a Wipe battery stats option in TWRP you could try
Just had a look through TWRP and didn't see anything related to resetting the battery. ??
I'll see how the trickle charge works.
Hmm, just checked and can't see it either, was sure Id seen it somewhere
There is a way to do it, maybe it's not built in and needs doing from terminal or a flashable zip
If I work it out i`ll let you know
EDIT - Looks like this does the same thing

Let it trickle charge overnight and then charged with the asus charger this morning and it seems to be discharging normally (if quicker) now. Will have a look at that app, though.

Okay, so each time I reboot my phone, my battery capacity increases dramatically! At one point, I got the notice to put the phone on the charger, and after a reboot, I was back to some 25%? Just now I was at 40%, a reboot now brings it to 56%!
What exactly is up? I charged my phone till it said 100%, then used an app called battery calibration to remove the battery stats file, and then let the phone drain till it shut off. (I couldnt reboot it). I put it on the charger, and let it charge back to 100%. I am confused?!?! This is, by the way, a chichitec 1900mA/Hr battery which has lasted me about 16 hours so far today with pretty moderate use! LOTS of web surfing, internet, and about an hour of phone calls. Its at 50% (or whatever it really is). I know its a great battery, but I hate thinking there is such an oddity about it.
Should I charge back to 100%, then wipe that stats, this time with CWM?
Matt
this is exactly what i was talking to you about yesterday in my "charging times" thread.. seems lots of people are having this issue...is your phone brand new? could just not be calibrated yet

New battery, new ROM, it takes a couple of charging cycling for these things to get working properly....give it time after the initial calibration.
and its not a problem that the phone won't switch om after discharge, it just shows that your battery was completely empty....plug in charger and wait for LED to light!
Quick question,
Is the Battery Calibration (CWM wipe at 100%) a phone, battery or ROM calibration ? I know you need to go through a few cycles after calibrating.
I have done it and since changed ROMs a few times so just wondered. Phone is only a week old so far.
So this has happened twice now. I'm running on ARHD 4.1.0 w/ Bricked 1.0.
My battery will be running normally, normal drainage, etc., and then it'll just drop from 90 to 70% in less than an hour, and normally drain for another hour or so, and then at around 60% just die. I can't attach a screenshot since normal screenshot apps aren't working and the stock function keeps producing invalid images, otherwise I would, but it literally just looks like it got to 60% and instantly dropped to 0%, there's just a vertical line of missing percentage. I took my phone out of my pocket, expecting it to be around 40 or 50%, and it wouldn't turn on. When I hooked it up to the charger, it took a good 5 or more minutes to even respond to the power button. Do I have a bad battery or just incredibly out of whack battery stats? I have never had this problem with an android phone before, and I thought for sure one full charge overnight would fix it, but I guess not because it happened twice. Any suggestions?
Edit: I use an app called battery snap to monitor the battery level and temperature with a widget, I checked a snapshot history while it was charging and for a few seconds it was at 0.002 volts. But then it jumped back up to 3.897 or something around there. That doesn't sound very good to me.

I don't know much about this, but I don't think battery stats have anything to do while the phone is dead. Even if it does, the phone would at least respond after a minute or two, not 5..
My suggestion is that you can order an Anker battery which is kinda cheap ($15 I think) and try.
You won't loose anything
Edit: Try wiping battery stats, do a full charge, fully discharge and fully recharge again and see if it helps (In your case I don't think this will help, but huh, let's hope ;D)

Thanks, I'll try it. I flashed the new cm7, since I just got tired of sense woes. I read battery life on this was amazing, and I'm hoping it was just a bug with the kernel/rom I was using. Battery stats would've been wiped when I wiped for flashing this ROM, so I'll do a full battery cycle and cross my fingers. My only thought is that maybe, if the battery stats were screwed up enough, it thought it was at 50 or 60% but really it was more like 10%. I remember having issues after I flashed the custom kernel, where before I flashed I was at 70%, and when I rebooted I was at ~10%, and I was like what the hell? So it ended up dying on me, but then I turned it back on and it said 50% or something around there. And then it functioned as normal until it died again, for real that time. Hopefully it was the kernel causing the issue. I'll run a few tests with this and see. If it is the battery, I'll try t-mobile for a warranty replacement of the battery.
The battery measurements seem to be really quirky on this phone. When the phone is idle it seems to drain anything from 50ma to 400ma for no particular reason. You cant really rely on the % too closely
Yeah, I've found the percentages to be pretty inaccurate. Hardly an hour and a half on the battery and it's down to 84%. I did play a game for like 10 minutes and the screen has probably been on for 20 or so, so that's not incredibly unreasonable. I'm just waiting for that dropoff to 0%, if that happens again I'm thinking it's hardware, because I'm running an entirely different ROM and kernel right now.
So it just happened again, went from 42 to 14 after reboot, had to remove battery and reinsert to fix. But other people have reported this issue on cm7. So, I'm thinking maybe that it's an issue with android 2.3.5 or the kernel for it, since it's happened on both arhd 4.1 and cm7, both 2.3.5 roms. I'm going to try and flash faux's cm7 kernel over it and see if it fixes it. May or may not, might be a long shot but worth a shot, I'd rather not switch roms for a third time in the same day.
Alright so it's difficult to explain this fully but I'll try. I came across battery calibration information and I went ahead and wiped the stats. I then let it drain, charge full then drain again. Now as it was charging I decided to flash another ROM, done. So that ROM took a while to fully charge but when it did I got 13hrs of battery life out of it. Now when I charge it, pretty much it stays around 50% and wo't bump higher. Literally haven't hit higher after leaving it plugged for more than 3 hours. Anyways I'm about to flash a update of said ROM and use a different kernel that is know to be more stable. But curious if there is hope for my battery? I don't plan on wiping battery stats anymore, after further readings I see it's not worth the trouble.
I posted this in another forum and the response I got was somewhat weak. Instead of re typing everything I will cut and paste my posts and hopefully you guys can guide me in the right direction!
Here was post 1 -->
I just bought a Rooted Nexus S from ebay. It is running this ROM Nexus S ICS 4.0.4 stock OTA ROM (IMM76D)
Now, I know nothing about android, I'm coming off a series of old turd phones because i'm always breaking them. I'll probably break this one too, but hopefully not for a while.
When I got the phone I put the battery in and turned it on, then charged it overnight. It will only charge to 54% and stay there. I talked to the seller he said it charged normally for him. He said he did a complete wipe and USB wipe before he shipped it.
The battery seems to drain normally (I guess, I have nothing to really compare it to) from 54% but it would be nice to have it charge to the 90% -ish range haha. I allowed the battery to drain to 40% and put it back on charge, it been on charge for almost an hour and will only charge to 41%? Do you guys have any ideas what I can do to fix this? Is this a sign it needs a new battery, or a software glitch? The seller said the battery shouldn't need replacing.
Also in the battery app under setting, Android System is using 28% is that a lot?
My last question is an important one to me haha. Is there anyway to convert the querty keyboard to a T9? I 've gotten used to texting with one hand and T9 makes it so much easier to do so.
Thanks everybody!
Someone recommended I try the battery calibration app So I did!
Post 2
Ok, I ran the Battery Calibration app. I let my phone charge for hours. It would only charge up to 38% this time. However, the percentage was 38% but it was charged to 3810 mV (and would not charge past this point). And full charge is approximately 4200 mV according to the Battery Calibration app. So I assumed that 3810 mV was my current battery's max charge (keep in mind it is a couple months old) and set battery calibration at that point.
This is from the app description --> It's suggested, but not necessary, to let the phone fully discharge after calibration, then charged to 100% without break.
So thats what I'll do. I should mention that even though I ran the battery calibration, the battery percentage has been draining from 38%. In other words, my phone now reads 26% battery charge, but is at 3758 mV.
I'm thinking that when I go to charge it after fully draining the battery, it will hopefully charge close to 100%. It seems as though the percentage is the only thing that is off. Because the mV reading seems accurate.
Here is a screenshot, what do you guys think?
This site won't let me post the screen shot until 8 posts, but I will do that once I get there!
Post # 3
The app says to let the phone fully discharge after calibration. I am now at 15%, but mV is at 3658. Should I recharge when the percentage has dropped lower, or when the mV reaches a low point? Are these phones really this finicky. I'm starting to miss my old 2007 flip phone haha
It's now at 14% and now asking for me to plug it in to charge lol but mV is still way high (3655)
Post #4
update, charge % reached 0 and the phone shut down. Now charging, Current charge is at 0%, 3595 mV. No one has any idea whats up?
Shouldn't mV be near 0 when charge is at 0%, and be near 4000mV when charge is near 100%?
hopefully you guys can help me fix this issue. Otherwise it'll have to go back to 'ol reliable, the 2007, multiple cracked screen, nokia slider lol It's not pretty, but it works!
There is a built in safety feature in our batteries to prevent deep discharges. IIRC, the safe cutoff point is around maybe 34xx mV. I could be off, but its to prevent damage to the battery. Here's more on them
http://batteryuniversity.com/learn/article/is_lithium_ion_the_ideal_battery
As for voltages, a full battery should be around 4100mV. Mine tops out around 4196. I'm not too familiar with all of it though. Most of the stuff I learn is through observation and links others provide.
Thanks for the reply! So are you saying that when the voltage is around 34xx the battery charge % should be close to or around 0%. And when the voltage is near the 4000mV range the charge %tage should be approximately 9x%
Do I have the right idea here?
Its hard to say while its charging. My phone is at 4000mv around 70% so I don't really know exactly how it works. But a full battery should read around the voltages I posted. There's people on here who know more about it, so hopefully they'll chime in.
But yes. When its close to zero, it should be around that range. It will differ from battery to battery.
Ah k thanks! My original problem was that the phone would only charge to 54% and would not go past that point. I'm waiting to see if it will get into the 90 ish % range after running the battery calibration now.
The app itself doesn't actually do anything. The stats will get reset once the charge reaches 90% My girlfriend's phone was the same way. It wouldn't charge past 75%. I let the phone run dead and charged it while it was off and it fixed the problem. If it doesn't go to 90%, try charging while off and just letting it run until it gives the warning to charge, turn it off and let it charge overnight .
Ok. Well I let the phone run dead earlier today as I mentioned in one of the above posts. But I didn't charge it with the phone off. I put it on charge with the phone on, and now it won't charge past 11%
It just seems to be getting worse and worse? It's been going between 10% and 11% and has been at 11% for about 2 hours now. Maybe this time I will drain it again and try charging it with the phone off like you suggested.
This is slightly annoying
All else fails grab another battery. They're dirt cheap on eBay. Just get one from a reputable seller
Ok, so I let the battery drain. then fully charged it with the phone off. When I turned it on, it had 47% charge.
The guy I bought it from said that before I buy a battery I should download an app called rom manager and download a new rom. he thinks its a software bug because he had no problems with the battery when he was running cyanogen mod 9 on it.
I wouldn't mind giving trying this, except I don't even know what a rom is. Is it operating system? I like the way the phone works now, If only I could get it to charge fully.
Thoughts?
Ok, I just did a bunch of reading and downloaded ROM manager premium. Hopefully I get this figured out. Owning one of these phones is a lot of work
lts pretty much a pocket computer. Coming from an older type of phone, a lot of things are going to be different. Gotta start somewhere. Reading up on it and toying around with the phone will help in the long run. Trust me.
or not....

Haha, pretty much. I'm slowly starting to learn more. I didn't think there was this much of a learning curve, thats what took me by surprise thats all. I'm a fast learner so I'm not too worried. I didn't have time to play around on it tonight, maybe on the weekend. I found out I could use it without the sim card which is awesome! Because now I can use old faithful while I learn more about android.
Thanks for the help so far though, I'm sure I'll have more questions soon haha
Haha. Yep. You can have tons of fun just using it over wifi!
Do keep in mind, fully dishcharging a lithium ion (li-ion) battery deteriorates the battery even more. We only discharge because older phones use nickel cadmium batteries which need more maintenance to get to their maximum life span and use.
Off topic though.
Battery calibration just wipes your battery stats. You can do this by going into any recovery program eg clockworkmod receovery or team win recovery project. You can wipe the battery stats yourself. If that still doesnt work. Try doing a clean install of your custom rom or kernel. If your not on a custom rom or kernel. Nor your rooted. Try formating the SD card in the Nexus S (or fully wiping the sd card). Than do a factory reset.
Ok, so I finally had some time to learn to flash etc. After backing up, I downloaded and flashed the same rom from SD, I cleared davlik cache and also selected the wipe data and cache option from ROM Manager (I assume that this is what is called a clean install?)
This is the ROM I am using http://forum.xda-developers.com/showthread.php?t=1653713 Slightly customized stock ROM, rooted.
After start up I waited a while and then plugged it into the charger, it only charges to 54% still. Sometimes it creeps up. One thing I noticed is that if I use the phone while it is charging, it actually drains the battery. So it will go from 54% to 52% and slowly drain. Is this an indication of a pooched battery?
Any suggestions? I will order a battery. Where do you guys order your batterries, I read that the oem samsung 1500 is reliable.
Recently had to replace battery.
Phone was shutting almost immediately after it was disconnected from charger. Charging status when not switched on showed the battery kinda going in reverse. Phone was really odd as it would suggest the battery had 100% charge and then within minutes of disconnecting it was shutting down.
I tried a factory reset/refresh with no change. So I ordered a Genuine replacement battery off flea bay and installed that last Thursday.
Initially phone seemed ok, then wen a bit weird and shut down even though charge was like at 70% or so. Wouldn't restart until plugged in and then in shutdown mode the battery/charging indicator would show 0% and then very quickly showed 70%. Good bit though was it was going up and not down like before.
Fully charged phone overnight. It then seemed really good and lasted until Tuesday with 66% charge still showing. I had not installed FB or Twitter which made a huge difference. Then yesterday it just shutdown again. When plugged in showed 0%, within minutes back to 70% and then charged to 100% in the space of an hour or so.
So I am looking for any advice. Is this just calibration issues that the phone needs to get past. Is it possible the phone has corruption int he ROM.
I appreciate it might be a hardware fault but seems weird that the replacement battery is clearly showing a big improvement suggesting battery was EOL after 2 years use.
TIA

Same problem here i will try to install the oficial rom of xt890 if works i back here if not i don't know what to do
Sooo............issue is still present. Odd thing which I am unable to confirm, due to rnadomness of shutdowns, it that I think it is slowly learning the state of the battery as it originally was shutting down at 70% after 2-3 days on standby. then 66% hen 56%. I did a clear cache partition and a fresh install but still the issue was present.
Clearly the new battery is lasting longer than the old one, just the phone does not seem to know to reduce the charge indicator all the way to 0%.
Anyone any idea why this might be happening.
TIA

Just to add i'm having the same problem.
Symptoms started last week running the stock kitkat rom so i ordered and a fitted a new battery. Initially everything looked good phone said 100% left it over night and noticed it had shut off when i came back to it. Plugged it in to the charger and it said 0% so i charged back to 100%, booted up android and almost immediately it begins discharging rapidly, i would say within 15 minutes its back down to 0%.. I've done this a few times now even left it on charge overnight for 8 hours but its still discharging rapidly everytime. The craziest thing is even if it says 0% in android i can still boot in to recovery and flash away so clearly there is charge in the battery its just android thats out of sync.
What i've tried so far:
Different wall chargers/USB leads/Outlets
Wiped everything in TWRP and flashed CM11
Factory Reset several times
Various battery calibration apps
My next step is going to be trying RSD to flash the stock ROM but beyond that i dont know what to do.
I'm experiencing EXACTLY THE SAME ISSUE with my Razr i, replaced the battery and it's still discharging very fast
Eventually managed to resolve my new battery issue simply by fully charging and discharging several times. It started to hold charge after the 7th charge and after several more discharges it's now up to full capacity.
