dont know if you guys experienced this or not, it seems like i cant get my phone to be fully charged after the 1.5 firmware update, it takes like 10 hours to get it fully charged. So i thought it was my phone, but after i get the replacement from t-mobile, its the same thing, so i thought its the battery, but after i replaced the battery which i got from HTC, it turns out to be the same....what do u guys think what happening to my phone ?
for example, if i charge my phone for 2 or 3 hours, and it says its 60% charged...then i reboot my phone, the battery bar becomes full, and i check the battery info, its 100% or 99%.....so you guys think it's the software issue ? maybe my phone is already fullly charged, but it just cant recognize it ? but this cant happen to 2 different phones with different batteries right ?
This happens to my phone even i flash it to the cyan 4.0.4
CyanogenMod-4.0.4
HardSPL
2.22.19.261
Please Help !!!!
weird, have u tried to UN-root?
ya...tried...was back to normal once when it was at 1.0 firmware, but then after i root or updated to 1.5 firmware, it happens again...i dont even know why this is happening
Anything running in the background sucking up battery power? Bluetooth enabled? Music/Video player "stopped"?
There is a file you can delete to make the phone forget its battery charge settings and start over. I searched but with the old Cy threads gone I can't find it. Try searching the forum a few different ways. Maybe it is also in a different rom thread. If I come across the file name I will post it here.
if i delete the file, would it indicate how much battery is left ? or how much battery has been charged ?
i think the directions on what file that needs be deleted are in the experimental thread, i remember reading about it as well. basically, what you are doing is deleting the old battery readings and the files that tell the phone how much juice the battery has left, and when you reboot after deleting them, it causes the phone to create new ones.

Try deleting batterystats.bin in /data/system if you upgraded without flashing. This will recalibrate your battery...

@StanSimmons thank you for finding the post.
in the recovery console
Code:
mount data
rm /data/system/batterystats.bin
reboot
Good job finding that post. I wish they would open the thread back up just for the troubleshooting info it contained.

they don't want it to turn into another "I hate google" thread. i am pretty much sure that is the reason they locked it.
so if i delete batterystats.bin , the battery indicator would back to normal ?not just going up by only 1% for every 10 minutes ?

what command ? im not a tech savvy guy...so i will make sure all things are ok before doing anything to the phone.
i put the command up in the first page of this hread ,and it was still there when i looked a minute ago.
so after i deleted the file, and i go to the recover console and type the commands and thats it right ?
i tried....didnt work....
i rebooted to recovery mode, then select console..input the commands....reboot the phone...problem still not solved....hmmm
If I remember correctly wasn't the procedure for resetting the battery to completely drain the battery till the phone shuts off on it's own, then charge the battery while the power is off till charging light turns green, then when you boot your phone use the terminal or adb to remove batterystats.bin

Yes those are the proper instructions. Don't do this very often though, its not good for Li-ion batteries
What an interesting problem. I have never run across this problem before.
The instructions to flash roms states that we have to fully charge our phone before flashing. Does that mean we have to bump charge to 100% or is a battery charged to 97% considered fully charged.
The full charge is a recommendation, not a requirement. Its likely your battery may not be calibrated correctly if you do not fully charge the battery first. There is a lot of complaining about a ROM killing batteries, after a flash. If you do not flash with a full battery, you should cycle the battery 3 or 4 times and/or calibrate the battery before making any observations or comments about the battery life of your ROM.
Personally when I flash a ROM I start with a odin flash to stock. Then I turn off the phone and charge to full with the phone off. Then boot into recovery, flash CWM (twice) and flash my ROM.
97% is probably fine, but keep in mind your mileage may vary.

not comletely true...
if the phone is already calibrated (or doesnt need it) the battery is fine
the phone ALWAYS charges to 100% then stops charging
lets the phone run on battery power down to 95%
starts charging back to 100%
so depending how quickly you unplug it after it reaches 100% it will start to run down.....

So ... if your battery is calibrated, and you flash a new ROM, thus obliterating the file your phone uses to retain said calibration data, you phone will still remember the calibration info?
I wish I had your phone, mine behaves quite differently.

I have flashed probably 60 times and have calibrated my battery about 5 - 6 times. I've had no issues with it at all.

It depends sometimes on the rom. Some of them charge full but don't show 100% when unplugged.

Thanks .... that added and changed nothing about your response.
Let me slow it down a notch. I said if you flash with low battery you *may* (I used "recommendation" due to using the word "may") have a calibration issue with your new ROM, until your battery is recalibrated. (Based on many hurried flashes) I followed that up with a disclaimer that not every phone behaves the same.
You said that is untrue because your battery constantly dances between 95 and 100% when left plugged in. Just like your newest response this serves absolutely no purpose in explaining where you disagree and why.
Once more for the hearing impaired: your battery stats is a file on your phone. Still with me? Okay. When you flash a new ROM, all the files on your phone are deleted. Still there? Good, I'm glad you're keeping up. So if you delete all files, how does your phone still have that file?
So I guess there are people that have phones that magically retain the battery stats file after deleting it. I was simply saying I want one like that, because mine doesn't do that.
Use your words, without resorting to name calling or cursing, if you don't want a sarcastic response.

Except you're wrong. When you flash a rom it does not overwrite all files found on your phone. By running a master clear, you can clear out all system files and flash back to stock which will generate new files.
However, it is not necessary to run a master clear for all roms to be flashed. For example, I went from cognition to Paragon without running a master clear and its been a fantastic experience thus far. So, if you didnt run a master clear, your phone still retains its battery file and may take a while to learn its averages. Running a clear battery stats can help your phone learn faster.
To explain this further, take a look at a statistically normal distribution (bell shaped curve). Over time, your phone learns what 100% to 0% is an all in between. Well, over a long enough timeline, your battery starts to get closer to the average which means it will start to say that 98% is a full charge and continue to decline. Its just what happens with batteries. If you clear out this timeline, you start to generate new means. This will not restore the life of your battery but it will give your phone the ability to be more accurate about its current state.
Thank you for responding, including where you disagree.
I misunderstand what the screen and odin say when you flash. They both say they are clearing and wiping the data and cache. I almost never do a "Master Clear" from odin.
So when the ROM process says its wiping DATA, CACHE, SYSTEM etc. the respective folders on your phone aren't deleted? That is where I was getting the basis for my commemts. Along with observations when flashing ROMs. Like starting with 60%, using odin to go to stock, leaving md with half of what it said before, flashing a new ROM, and having that ROM say 80%. Then rebooting the phone to have 50%. Then plugging in and rebooting to see 80% again.
If I'm wrong I apologize. All the info I know from flashing ROMs is reading my screens, and interpreting my observations. Maybe my phone IS jacked up, it does this everytime I don't charge to full with the power off before I flash a new ROM.
Sent from my SAMSUNG-SGH-I897 using XDA App
I didn't charge to full before I flashed either. I'm not an expert by any means but what I posted is my understanding of what happens.
As for what your phone says, who knows what I really is doing. I mean the general process is understood but the specific files and folders that are cleared would be hard to identify.

i can only get my nexus s 4g to charge up to 97% if i have wireless tether enabled... otherwise it considers itself full at 95%
not sure whats up with that
This seems to be quite a common and somewhat obscure at the same time.
Many people have reported installing a new rom or even just powering up their phone and seeing a battery % much different from what they expect. Most often much lower than it should be. Evidently this corrects itself after some time but it's a real problem if your display reads <15% because you really have to plug it in then, even with you know you have 90% battery!
So, here's the solution after testing it under different circumstances over a few days:
Simply boot your phone when it is not plugged in to a power source and battery % will be accurate.
That simple. Silly LG!
So, if you flash a new rom, unplug the USB cable before you reboot...
Hit 'Thanks' below for the 50 reboots I did to prove this...
hehehe jups allready figured that out on myself tho haha. But indeed that's kinda silly of LG

Sorry to say the same..
Even while charging with the phone shut down, pulling it off the charger and then booting this happens. On my phone I have experienced it on all MCR's.
It's really not a big deal as long as the battery performs as Stock 10b, that build has been stable batterywise on my phone. But staying stock isn't too much fun
Well, every time I charge, whether I reboot/shut down before unplugging or not, my charge always maxes out at 96%.
Annoying and I'd like it sorted if at all possible.
Anyone?..........lol

ye i got that exact same issue i was wondering why that was happening and hoped that a simple reboot would fix it but its a bit more complicated than that i suppose...
also the battery reset in cwm didnt fix the loading till 97% w/e percentage.
when i install the stock rom it allows me to load it till 100% though pretty weird stuff -.-

I had a replacement netbook battery that could only max to 90%. So, over the weekend, I practically drained it to 0% (not a healthy practice for Li-ion batteries but I was desperate). Took out the battery for a while, and then recharged for several hours. Well, it seems to get up to 100% now.
Perhaps you could try using the the phone until it very low on battery before recharging. Maybe the charging process in the phone needs some sort of recalibration. But should not be doing this all the time as it will reduce Li-ion battery longevity.
Let mine totally die last night so it wouldn't even turn on at all. Took out and replaced battery and then charged it overnight and hey-presto, when I unplugged it this morning, it stayed at 100%.
Solved indeed....for me anyway. Feel free to try the same and post your results.

I'll be sure to try your tip man. But not easy drain it completely when I always need the phone :=)
I guys! I've got the same problem.
I think that it could depend on the "full battery popup FIX" that Paul introduced in his roms by the FR8.
So I would like to ask Paul if you can create a patch to remove that fix. Just to try it!
According to me, incorrect battery amount depend on a wrong voltage read error (offset introduced?) by the rom. :blink:
In my case, I have followed many times battery wype procedure without positive issue. The matter leaves only by flashing original roms.
I think that if Paul have written a wrong battery values range (to delete the battery full popup) that can be traduced in an incorrect battery status displays.

Perhaps, but you can not conclude it was introduced by MCR. You logic is wrong there.
Even without "battery full popup fix" it doesn't work good...
Battery level, when unpluged, stay at 100% for 2 minutes afterwards drop down fast until 85% then drain normally...
I'm getting huge battery display problems no matter what I do.
When I took it off the charger this morning, it said I had 100%... thats fair enough. However it stayed at 100% all day, so to "refresh" it this evening I restarted the phone, and low and behold it now says I have 27% left. But again, it's just sticking at that value, even with me now plugging the phone into the wall to charge. It simply says "Charging (27%)" and won't budge, likely until I restart the phone again.
Sometimes it works fine, it seemed to be doing ok last night before I put it on the charger. Any tips/suggestions? Is this something likely to be fixed when the Gingerbread update rolls around?
This is my first real smartphone, and am fairly annoyed as its giving me a fair few problems that I've not had from other electronic devices.
As I stated in another thread, I had the same issue while on MoDaCo Fr12. However, after reverting back to stock, the battery percentage is spot-on and I'm getting up to 48 hours use out of it.
Draw your own conclusions.

That sounds super, but I'm still on stock too. About the only things of note I've done are root and switching to Launcher Pro. Oh, and Clockwork Mod of course. Perhaps a complete reboot is needed, we'll see how it goes.
Saying that - since charging, my phone has been at 90% all evening, until right this moment when it changed to 89%. It's less than I'd expect on this type of phone for 3-4 hours use (or lack thereof, I've barely touched it), but it's a start eh?
Welcome to the world of smartphones my friend. I've had various handsets over the last 4 years from iphone to android and a day and a half out of the battery is about average......at best. ;-)

Just to clarify, what I meant in my previous post was that I was expecting to battery to drop a lot more than it did. The fact that it only went down 1% in several hours of use prompted me to think that the battery value was messed up.
As it is, I've not charged my phone in the 36 hours since, and it tells me I have 73% battery left. Perhaps it is performing extremely well after all? If that's the case then I'm more than happy with it, but being the pessimist I'm still expecting the phone to turn off sometime with the battery reporting incorrect values.
I have 2 batteries and one broken phone, I use the broken phone to charge the extra battery. If I reboot my phone with a battery with a perfectly good charge when it reboots it shows the battery is dying? If I put the battery in the other phone and charge the status says the battery has a charge, not sure what is wrong?

My guess: Your broken phone doesn't actually charge your battery or at least, not fully. It might think it's fully charged at a very low %.
It could also just be the os not reading the charge correctly. I've had it happen on numerous occasions where I'll reboot my phone and the charge drops by 20-30% after reboot. But if I continue to use it without charging or rebooting the percentage will eventually increase or at the very least stay at one level for an extended time.

You should probably stop rebooting, let it die and fully charge it. Might need to recalibrate your battery stats too.
As for your IMEI being toast, you can flash stock KK4 to fix it.

Well what I'm starting to think is that the way you charge your battery has nothing to do with it. The OP missled me to think that it was coming from your broken phone. It might come from your phone (or app/setting on your phone).
Imo, backup your apps and such (after finding out what's draining your battery), flash back to stock and start from there to get back to your ROM.
How old are the batteries?
Do they both report the same percentage immediately after boot and after comparable use for a similar amount of time?
They are only good for 500 to 1000 cycles. A dying battery will appear fully charged when on the charger but quickly drop to a lower voltage when used.

Latest AOSIP rom with Hellscore kernel, stock settings greenify, full discharge and recharge, all seemed so good....
And then boom. Go to reboot to recovery and I get the little empty battery icon upon reboot - but I was at around 40%?!
I use the battery calibration app, for what it's worth knowing the debate about the battery stats file. I've done the bootloader logs 'trick' and still I get a random occurrence like this?!
Anyone else been plagued with this randomly happening to them?
There are so many reasons it can happen. on thing id recommend is install ampere form play. Using this you should be able to monitor the voltage of the battery and at least know that it is operating within the correct range. if your 0% voltage is too high, it could rule some stuff out.

Cool. Just periodically check the app and jot down the percentage and voltage. keep doing that until its ready to shut down. preferably a reading every 10-15% if you can but really important is to try and capture readings just before and after any drop off you may see.

Perfect thanks for the advice, I've got it installed and now juts doing a full charge.
Following that drop out, the device then reported 7% battery so I let that go flat and now fully recharging.
If it's the case that there is something going on here, how can the issue be corrected? Does Ampere help configure reported VS actual readings, or does it purely show what's being drained?

Following that drop out, the device then reported 7% battery so I let that go flat and now fully recharging.
If it's the case that there is something going on here, how can the issue be corrected? Does Ampere help configure reported VS actual readings, or does it purely show what's being drained?

Its worth getting a voltage reading now too then, to see if it is as low as expected. As for solution, we need a root cause first.

Ok here is my first screen. I'd browsed Facebook (web version) and watched a video or 2, battery dropped to 97% soon after.
Yep. Just keep going. Every 10% is fine. No more than that. Actual battery charge is voltage so we just want to see if there are any conflicting data sets later on

It just did it again!!?
I had even doing the Ampere monitoring but didn't go all the way down. But today I just experienced the random drop out again. Strangely when I booted back up, it was as if the cache had been wiped as the Android Optimising app screen came on.
This was from the other day though, if this helps?
The other day did it seem to deplete normally? I'm around 20%/right now and see similar voltage to you.
Sometimes my phone used to crash and when it booted up I had this graph / drainage issue. It's as if it goes into some manic sleep that kills everything. What you've got here seems similar. I don't think there's an issue with the battery cycle itself.
I'd be tempted to do a factory reset and start clean to be honest.
Is the back of your N6 lifting away from the frame? I had this issue too and ended up doing a RMA because the battery was bulging.

Weird and annoying isn't it!
I've recently flashed this new rom and so has been a fresh start so I'm kind of at a loss as to what to try next.

Just took off my case and checked and all seems normal, back doesn't appear to be coming away and seems to be ok.
It's times like this I miss my good old Note 3, never had a battery life like it for its flat lining ability!! (see attached)
If it were the battery capacity due to bloating, I would expect to see the Voltage value to be wrong
Go back to stock and run it with no restored apps / data. If it still happens RMA

Just when I think I've got it all setup nicely...
Latest AOSIP rom with Hellscore kernel, stock settings greenify, full discharge and recharge, all seemed so good....
And then boom. Go to reboot to recovery and I get the little empty battery icon upon reboot - but I was at around 40%?!
I use the battery calibration app, for what it's worth knowing the debate about the battery stats file. I've done the bootloader logs 'trick' and still I get a random occurrence like this?!
Anyone else been plagued with this randomly happening to them?

Your battery calibration is messed up. It happens.
DO NOT waste your time with "battery calibration app" -- there is NO software you can install and run from Android that will have ANY impact AT ALL on the battery calibration. All those "battery calibration" programs do, is delete the battery stats file, and all the battery stats file does, is store a log of what programs are responsible for how much resource utilization -- nothing at all to do with calibration.
Battery calibration reset is done through the BOOTLOADER.
Reboot your phone to bootloader. Scroll to "bootloader logs". Press and hold power button until the phone shuts down.
And that is all there is to it.

Thanks for the reply.
Unfortunately, I have tried this many times and so there must be more to it than this. On my latest rom, I had wiped phone and clean flashed whilst phone was connected and at 100%. Therefore a new clean install whilst phone was at 100%. I cleaned that stats (for what it was worth) and also did the bootloader logs trick. I would have thought that would have solved the issue, but as reported it still happened.

Your calibration is fine because the % matches up to the voltage, which is all calibration matches.

Thanks yeah, I thought as much.
The question remains then..... What in earth causes these drop outs!

It's hard to say. It seems like the system may be crashing or something at that time and causing an inordinate drain. Thats what mine used to do sometimes.
