Hi everyone,
I am having strange battery issues. When the phone is switched on and charging, it charges very quickly (an hour or so). But it also discharges just as quickly - I talk on the phone for 30 minutes, and battery indicator is already on 3/4th green. Maximum time I can get out of it is 15-16 hours standby, and normal calling.
However, if I switch off the phone and charge, it takes longer to charge it (around 2-2.5 hours), but it also retains the charge longer. Maximum time I can get here is 35 hours standby, again with normal calling.
Also, my indicator is quite weird - when my battery information (in *#*#4636#*#*) says 34%, the indicator still shows 1/2 green.
I had done a "wipe battery stats" only once, when I had upgraded from EPF21B to FRF50. I have since tried CyanogenMod, and updated from nand backup, then went to FRF72 etc., but I have never done "wipe battery stats" at that time. Could this be the cause of my problem?
I realise this may be a battery calibration issue, and I have read many threads, but I am unable to find the authoritative way to re-calibrate my battery. Please help.

In addition to my other issues, refer to thread http://forum.xda-developers.com/viewtopic.php?t=43272 (ERROR: ITWriteDisk - An internal error occurred), I have noticed that battery meter on my 8125 flashed to the the imate aku2 rom, is always at 100%. I'm unsure whether this will effect charging since when I plug in the charger, the led turns green immediately and stops charging, and I have had the device turned on for 4 or 5 hours disabling all the power saving features, leaving the backlight on, turned on BT and wifi, and its still at 100%... either its a great battery, or somethings screwy.
small update.
after about 5 hours the battery meter started to drop quickly. Although this is good, the problem that comes up for the first 5 hours, you cannot charge the device as it thinks the battery is full.
Am I the only one experiencing this?
same here.... after 24 hours battery meter droped from 100 to 94
bafore it was 90 after 24 hours
maybe they improved something.. thats why it does not go so fast as before
I think it is the fact that the new rom seems to be much better with power consumption. I am getting almost a 50% gain between charges due to my pattern of usage!!! Very happy!
I'm more then happy at the battery improvement, what I am not happy about is that if this is a bug (granted there is improvement), the problem becomes when charging the phone, so I have it for 12 hours, its still showing 100%, I have an offsite meeting the next day, and would not be able to charge the phone for the entire day, the battery will start to drop very fast since the phone thought it was fully charged, when it really was not... I'm confusing myself here, but I think you understand what I am saying.
Also, while my battery was at 84%, I did a soft reset, when the phone came back up, it showed 100% battery and refused to charge... this is a problem.
You might want to inquire about a replacement device or battery - in case it's not the sotware.
My laptop has this issue. It's always been on external power and somehow that's weirded out the control circuit telling the machine how full the battery is. It will read 100%, but it's actually at 75%. Then if I disconnect it, it will go down to 5% in 8 minutes. However, it will happily run for 3 hours+ on that last 5%. Similarly, if I hook it back up to the charger, it goes to 99% (leaving the battery indicator light amber) in another 8 minutes. Takes many hours more for it to get back to 100% (making the battery indicator light blue).
With any luck the control circuit will be in the battery (I believe it is), and the easiest way to check is to exchange your battery for a temporary new one and see if the problem goes away.

Agreed.
If you think your battery is stuck - just do this little test.
Turn on Bluetooth, WiFi, make a GPRS connection, and set back light at 100% and don't let them turn off or let the unit power off. The battery should drain pretty quickly in this senario.
I thought mine was stuck, but it dropped 5% in less than 10 min in this mode.

I'm not so sure its the battery.. another issue that I just noticed, is taht even though the backlight is turning off, the screen itself is not turning off after the designated time I set...... this is rather bothersome as if I forgot to manually turn off the screen.. it remains on constantly.
Even with my original Qtek 9100 EN ROM, the screen doesn't turn off - only backlight. If you want the screen to be off, you'd need to go to Standby, or use a third party utility to turn the screen entirely off.
Although lithium batteries are best kept at a full charge, they should be periodically drained to recalibrate the fuel gauge.

I was also having this problem but after about 2 days use it began to go down. My G3 device seemed to hang at 100% and drop quickly after it hits 25%. I believe this must be a hardware issue as I now have a G4 (setup identically to the G3) and it does not have this issue.
i am having the same issue but i believe it the battery because my phone 8 months old and if you read the battery thread it has all the same issues your having
I'm worrying about my battery. The main thing is, it drains really fast. In flight mode and nothing else on it drains like 2% each hour. So overnight, most of the time it drains like 16%. Today i started with 100% in the morning. Used GPS for 1 hour, made a phonecall for 20mins in total time. My battery indicator said there was 30% left :/ I know this thing eats batteries, but this is insane. Because i noticed an incorrect display of the battery the last few days i gave it a soft reset. After the reset i saw the battery had only 4% left, not even 30%, but 4! :|
Many times when the phone is saying i have 'insert number' percentage of battery left it's incorrect. Because when i give it a soft reset, it changes the number. Sometimes i get more percentage back, and sometimes it drops.
One hour ago i plugged it on the charger, checked 45min ago, and it was still on 31% battery :| Then, like 10min later i suddenly saw a green light from my phone and it was full.
I've never had a device with a broken battery and i don't know the symptoms, but is this normal or is it likely that my battery is dying?
A little kick!
This might have been answered somewhere, but i couldn't find.
My kaiser takes an hour atleast to get to 67% battery level on the power adaptor and as soon as it reaches that level it takes just 5 min to get to 100%. This is very strange. I performed a Radio upgrade to 1.70.19.09 a day before. But this is strange?
The battery status app starts with whopping +600mA of charging current on a 0% charge and drops to 100mA at 50% charged and to +53mA when it is around 67% and then in some time it says 100% with a charging current of +53mA.

Have you tried changing the radio back? To see if that affects anything?
Is your battery life normal? Does the same happen if you let the battery discharge once and charge it again? Changing the radio could have reset the battery meter calibration and it's just finding its way again.

Do you mean to say that i should give a few recharge cycles( a week may be) and this should be resolved?
Run the battery down completely once until the device turns off, that will also allow you to see if you have normal battery life, then recharge fully. Once is enough.

Doesnt work. I completely discharged my kaiser such that it switched off automatically. Recharged to 67% and then shortly 100%. i dont see 70-80-90% charges.
Once it switches off, remove the battery, wait 10 seconds, put it back in, turn on again. If the phone still says low batt and turns off again then your battery is really empty. If not the calibration is really off, run down again until it's really empty, then recharge without interruption until you get the green LED.
You didn't say if your battery life was normal.
same problem here
I have experienced the same issue. Battery is less than 60% and suddenly it reaches 100% (in a couple of minutes). My battery life seems actually very short to me but I must say I started using HSDPA the last week (my carrier finally offered it) and off course my battery lasts much less than before, so it could be just an impression. I flashed hyperdragon III Blackstone (nov 1st) last weekend and the radio is 1.65.24.36.
Just to give you an example, this morning I was listening to streaming radio over HSDPA and battery dropped from 100% to 40% in 50 minutes (screen was off all the time)
So I will try to empty my battery completely and charge it again. I´ll report after that.
Hello,
I recently got my nexus, and rooted only two days after receiving it. I installed cyanogen's latest. I am getting low battery; in only 5 or so minutes, the percentage goes down by at least 2 percent (while using). I looked to see what may have been draining the battery, and found that the display alone was using 62% to 75% of my battery. I tried undervolting, but the display seemed to still be in the same draining range...
Is this a hardware related problem, or is this a common nexus thing?

same here, really starting to piss me off when i see people talking about 70% battery at the end of the day while my phone dies in 6 hours
Cyan?
Woah, I think this might actually be cyan's Rom.
I flash enomther's rom and i got display percentage at around 15-16% ...
I think cyan will look into this soon enough...
But for now... I guess I'm gonna wipe... :/ and stick to enom's or some other ROM...

C´mon....see my signature!
More than 10h now, Wifi on all the time -> 70% battery
This is not that bad

I think the problem is only with a few people, but I know others are experiencing this. This might be something with the "latest" nexi. But idk, it's a mutual issue, a fix should be coming
Probably you are right...
But, I would like to know, what settings peolple use: like updating wheater every hour, emails, widgets,..ham many apps are running and so on, ... perhaps connected to...sometimes people dont even know that
Edit: I got my Nex in january.
The change in the display usage percentage is just due to the way the powermanager works. Its not using more battery, its just displaying how much power it is using more accurately.
have the same problem.
100% airplane mode ON no WIFI, in 5 hours 72% battery remains . (PHONE IDLE took most of this - my G1 could go 1 month with this settings)
IN 12 hours in was 6% and with LOW use of my N1.
Yesterday I removed numbers in my battery and it was a litle better, not much but a little. (about 8% better)
I had 5.0.5.1, 2 and 3 and everyone had the same problem!
CM please take a look at this. What do you need any LOG info or something!
Have you tried wiping battery stats, then charging to 100% with it off, then booting into recovery and wiping battery stats again, then charging to 100%? The few times I've had battery issues that's taken care of it for me.
I flashed cyan again with a wipe (again), but got the same thing.
On enom's rom, I get beastly battery. I think we just have to wait for a fix for the people who are affected.

Do you need root to wipe battery stats? how do you do it?
Well I did the wipe battery about 3 times and in OS it was already green light 93% full.
I WIPED and put the power in on NON POWERED PHONE. It took 1 hour more to come to the green light . than I wiped again and went to boot up.
at 11PM i had 100% battery went into airplane mode wifi OFF.
And i did one other thing. Some of you had the battery drain issue with trackball wake. So I disable it.
7 hours of this and I got 97% - beautiful
before that I had 72% so there is a difference.
Now I have to see if the wakeup trackball is the cause of this or the wiping the battery stats.
Will eliminate one and other and keep you posted
I took my phone off the charger at 4:30am and the next day at 5:30 am i had 12% battery left. i used my phone a total of 3 times. most of the time it was on standby. i have setcpu with my phone UV and UC to try to save battery with profiles set up. in battery information 85% of the phones battery went to cell standby. Any suggestions on how to improve this?
Try wakeup trackball OFF in spare parts and battery % OFF in upper taskbar.
I have now from 100% to 59% in 7 hours. wifi ON all the time.
I have tried to wipe battery settings and charge fully with the phone off, but after the full procedure, I still get the same end result. I attached a picture of my battery usage.
Im pretty sure i saw a post online about the newer nexus's that were released having a better display. If this is true then wouldn't the phone's hardware alone be using more battery?
I can confirm I am having the same problem. I wasn't sure until I checked battery usage overnight. It used to be that with my phone on airplane mode I would use about 2% while I slept. Now, it's 9 or 10% with "Phone Idle" taking the lion's share of it.
I have tried deleting batterystats.bin after a full charge; powering off (while on charger); charging up to full again, but this has not solved the problem.
A few notes:
When the phone is idle (but not in airplane mode) it uses about 1.5% per hour (compared to about 1.1% in airplane mode)
I am using setcpu profiles to keep cpu usage right down when idle
Around the same time I upgraded to 5.0.5.3 I also started using the himem version of fastboot. And yes, if you suspect I don't know what I'm talking about here, you are quite right
For my next trick, I will try resetting battery statistics via recovery. What fun!
I've kept the cyan rom, and changed some settings to increase battery life. I turned off the battery percentage icon, and turned off the trackball to wake. I still got that the display was using a lot, but the battery still lasted pretty good. I guess there isn't too big of a problem on my side. It probably is the "newer displays" on the "newer" nexi. Maybe there really isnt a big problem
I changed now from CM to Enomther's TheOfficial Nexus1 1.8.1 and battery now works great.
I unplugged the charger at 12.00 am at midnight and with quite good use, not extremely havey but a good use I had 30% battery left at 20:00 (08:00PM) that day.
I lost only 2% from midnight to 7:00AM in my airplane mode and with Gmail check 10 min of phone calls wifi ON all the time checking web pages and showing off my live wallpapper at my work I had at noon (12.00PM) 70% battery left!
I LIKE IT!
now I'm thinking to push Kernel - .32 & .33 to see if there is any change with my battery
http://forum.xda-developers.com/showthread.php?t=653598
After resetting battery stats in recovery, I still lost about 10% overnight while on airplane mode.
For my next trick, I'll use a task killer like "Process Manager"* to keep everything unnecessary switched off overnight. Maybe I'll be able to narrow it down to an application if it's not something integral to the actual ROM.
*Yes, I know it will use up the battery too
Hello, I'm encountering a weird issue with my phone.
It seems to be happening when I don't fully charge the phone, even though it's kinda random.
The issue is that the battery is draining damn fast after charging the phone. The first screenshot shows how I lost ⅓ of my battery in 14 hours without having touched the phone. There's a difference between the beginning curve and the ending curve, that's because I tried to reboot my phone.
I do have AccuBattery installed, which is an awesome app. And it actually shows me than during this interval, I lost around 600mAh (see second screenshot). That should represent 15%, which would be a good value because I'm usually losing around 1% per hour. I shouldn't have lost so much battery.
So.. it seems that the battery is not being charged at 99% at all? I think my battery level has some issues. Because when charging, it usually stays at 100% for around 20 minutes, but is still charging according to AccuBatrery. This can be noticed on normal charges (third screenshot).
If a charge from 19 to 100% charged about 3300mAh and a charge from 7% to 100% charged about 3620mAh, my last charge from 10% to 99% shouldn't charge only 3400 mAh. And that's related to my problem of "phone is still charging even at 100%".
I already tried to empty my battery and fully charge it, I already tried to wipe cache, the issue is still coming back.
Is anyone else encountering this issue? What should in order to fix that?
Thanks in advance!
Bumping. Any idea? :/
Here is another screenshot showing the battery is being discharged with ~2000mAh
