I recently installed Serendipity and made sure the battery was at 100% while doing so (and deleted the battery file). I'm waiting for the battery to drain before I plug it in. Am i supposed to let it charge all the way again? Also, is it safe to reboot the phone while it is draining the first time? I want to install something using clockwork.
I'm being careful about this because cognition would report 14% battery life after 33 minutes of display usage and display eating up 96% of my battery....

There's a complete thread on this, I suggest you look it up.
After you reset your battery stats, it is suggested to do a few full battery circle (use til dead, full charge, rince and repeat). You should be fine after 2-3 circles.
Note tho that it will not improve your battery life. All it does is a attempt to tell your phone what % your battery life is exactly.
For your fast drain, I don't think it has anything to do with your battery calibration or your ROM. It's most likely a app (or a few) that are draining alot of juice or that are running w/o realy being needed. (Check your running services.. make sure you know which one to stop and not to***)
Also using a app/widget like advanced task killer can help your battery life as it will stop every app running with a simple touch. I suggest doing it anything you're not using your phone.
One last thing, display eating 96% of your battery is normal.. it's not telling you it's using 96% of your battery. It's telling you that during the time your phone as been unplugged, your display use was your main action.. probably cause you didn't make many calls or anything else.. Display is just about everything you do with your phone so it will always have some high numbers like that.

Yeah, I've seen the thread before but forgot about it. Thanks for reminding me. And my point about the display was that it was on for such a short amount of time, yet still killing my battery.
I am now down to 30% or so after 3 hours or more of display time after calibration & rom switch- and I was streaming music through WiFi and using Bluetooth headphones. So it it seems like it made a huge difference =D
Thanks

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...

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
First off I can't spell battery............
I have an ATT Captivate that I have fixed by installing FF3 and Kernel 2.6.32.9 as a package from this site. My battery life isn't noticably worse than it was when it was the stock 2.2 but it still sucks. After 10 or 12 hours of very light use its down aound 15%. The battery use says it's hands down the display thats using the juice.
I was hoping (maybe wrongly so) that having the additional access to the phone I could somehow improve my battery life. I've tried the bump charge, recalibrate, CWR erase battery stats, etc. I also have 2 batteries for it (that probably tells you something right there) and both batteries behave the same.
Does anyone have any suggestions on this? Is there a launcher that I can use that's battey friendly? A different ROM?
It's a shame to have this phone to the state it is with a FF3 rom and faster than it was and not be able to use it all I want.
TIA, Jeff
Some things to help get the best battery life are:
Place screen brightness at lowest level both on web browser and on normal screen.
Switch to 2G when not needed for downloading/uploading data.
Turn off power saving mode under settings/display.
Use as few widgets as possible.
Manually retrieve emails rather than having them sent to you every 30 minutes or less.
In cwm there is a battery settings menu (can't remember what it is called) but you should enable that also.
These are some of the better ways to get better battery life out of your phone.

In 10-12 hours you only have 15% left on your phone? How much time is used for display? My phone can usually last a good 15-20 hrs with light to moderate use. As we all know display is the number one use for battery consumption. I've noticed I can go about 2 and half hours give or take on display before my battery gets kinda low.
As the previous poster has mentioned, screen brightness and data usually are the culprits for bad battery life. Try leaving your screen brightness on a low setting, and turning auto-brightness OFF. Disabling background data in "accounts and sync" setting is also a very good way to help with battery life. Also, making sure your GPS is OFF is another good way to save some juice.

Flashed ROM (FF3) while batt low?
I'm pretty sure the batt was not 100% when I flashed to FF3 and I did not clear everything out before either. If this is a potential problem with batt life can I fix this short of reflashing on a full batt?
Is going into CWR and restoring from a backup going to do the same thing as reflashing FF3 from the batteries perspective if I clear everything first?
TIA, Jeff
After a difficult update with Kies I was able to upgrade to Gingerbread.
Everything seemed to go well the first time then I found drain battery and slowing down on the system.
So I decided to make a simple wipe which reported the phone as fast as at first, but the battery still has problems.
In one night from 90% it was completely drained so today I decided to use 'Battery Calibration' made from user 'marosige'. This time in 5 hours I lost 30% of battery life using some sms, internet for 15 minutes, and playing cut the rope for 10 minutes. More or less.
However I have to see if the battery loses all of a sudden like last night which is the biggest problem.
All of this is not normal have you any advice?
Thanks in advance
Hi Fattox,
Dont worry your socks off I flash Roms quite often and this requires me to calibrate the battery. Sometimes with certain Roms I find the battery may drain quickly the first time and then things get better.
You say you have calibrated so that means the app you used should have deleted the old battery stats from your systems file. In saying that if you follow these next few step you should be ok (unless there are other issues causing the drain)
1. Make your you drain the battery fully until phone dies and can't be turned on by pressing the power button then....
2. Plug in phone and keep it off until battery is fully charged. Don't take it off charge as soon as it says full. Just let it go for about an hour more or so to ensure it's at capacity.
3. Turn phone on and use as normal until dead...
Providing there are no other issues causing the battery drain you should find your battery usage to be satisfactory. Remember to turn off wifi and gps when your not using them as well as maybe turning your screen brightness down. Anything that uses less power the better....
Hope this helps.
between the recalibration with the app and your point 1, I had the same problem: during the night the battery loose all the energy.. so strange.
All this after I upgraded to Gingerbread.
I'm going to test all this week then I'll spend my warranty.
Dear Android Community,
Overcome-day to all!
I've upgraded to "Overcome-Jupiter" 3 days back and though admittedly the new ROM is smooth and fast I believe am noticing some irregularities on the battery.
I have a question and situation, wherein in battery statistics is is show that "Display" is using around 96% of the batter, all other task including the "Android system which is only 2% is for the remaining 4%.
Furthermore for a full charge, am getting around 14-17 hours usage on the batter.
I've done a "battery wipe" and have done two discharge cycle.
Any other Galaxy tab7 user here having the same issue, your comment, suggestion and recation on my query is greatly appreciated.
Thanks in advance.

As for display that is normal since Froyo especially with heavy use, the beast display consumes the battery more than anything. As for the battery life if its on moderate to heavy use that seems quiet normal even good actually (remember official stock firmware gives you 7hrs on heavy use). Finally read the tips and tweaks section on our website for more info.
I have heavy drain on the battery after upgrading from Hermes to Jupiter. (All apps and setting being similar)
I can get only close to 5 hours of continuous usage compared to about 7 hours on Hermes. You're not the only one to be affected...... I've posted my cries for help :
http://forum.xda-developers.com/showthread.php?t=1176978
I'm still monitoring to see if there's improvement after a few charge cycle.
Darkpal,
Thanks for the quick reply, I have to agree with you on the display thing. What I wanted was actually, just a confirmation from other users that they are having the same battery statics. This will then confirm that everything is normal with my "precious/fragile SGT".
I will do further testing and monitoring.
To PCdumb,
Cheer-up buddy, still I believe our SGT is one of the best tablet out there. ADB and the Overcome team can only do so much nho.
To Darkpal,
On a final note, will the "app lucher" (am using "go launcher EX") will have and effect on battery usage, any launcher you can suggest.
Thanks again for the help
Launchers if coded correctly shouldnt have that much impact if at all on the battery. I personally am using the stock launcher only because am too busy or lazy to configure ADW launcher EX which I have an recommend

battery % weird
Hi. I have a strange question in relation to the topic. I use a P1000 running Gingerbread (stock no mods). I hope you guys have some solution to share to me.
I had Battery Monitor installed so I can check the battery usage and percentages, and Juice Defender Ultimate to you know, save juice.
1. There are few instances that when the unit still has 10% or below power, I sometimes encounter unit shut down (powers off) while I am browsing. So I turn it on again, the Samsung animation appears, but still turns off. Therefore I am forced to charge it (using mains plug). Is that normal?
2. Coming from a critical low battery (5% or lower), with the unit off, I leave it charging (using mains plug) until the battery goes full green (full). 4 hours or so if I am not mistaken. When I turn it on, Battery Monitor displays only 76% or 81% power.
I find that strange since it is supposed to display 100% right?
3. At 76% or 81% while unit on, I plug it to charge again, but does not increase percent anymore.
4. Upon my gut assessment, the unit still performs normally, the standby time and usage time are still as expected, the battery is working fine.
TO DO:
I am thinking to just clear data and reinstall battery monitor.
I am also thinking to install another battery application to display percentage for comparison.
In any case, is there a way to calibrate the unit when turned on to display 100% when it is really full when charged off?
I am not modding or rooting it, I am just a basic user. Any ideas? Thanks!

Try to reflash or factory reset then monitor the battery without installing the battery monitor.
I use "battery doctor to save battery" from the market. You can try that but try first without a battery monitor app.
did you try to use another usb cable? or perhaps your charger is not the original? loose internal battery connector? there are so many factors that might cause your problem not mentioned.

Thank you for the reply bongski. Without any battery monitor app, the problem is I cannot see percentages. But anyway I will do the factory reset, it is another option but I find that drastic and will be the last choice. Also, the USB cable and the charger is the one that came with the Samsung box so they're original. The loose internal battery connector is a bit far fetched, the battery is not user accessible and also the unit is not dropped and carefully handled.
Hopefully I get accurate readings, I will update here.
The battery percentage is in settings/about device/status/battery level.

ok. well i did the following
1. clear data and reinstall battery monitor.
2. install another battery application to display percentage for comparison.
i tried the battery doctor but provided the same percentage reading.
so i just factory reset the thing, and i am observing now (ie. charge later and see if the issue persist). i've no knowledge on how to reflash the thing.
well ok to clear all my doubts i just factory reset it. then i reinstalled my initial apps (including battery monitor), used it til it died (1% until it off itself). plugged to mains, turned it on, and let it charge while ON (of course screen is off). took 174 minutes (3 hours) when it reached 99% and stayed 99% (looks like it does not touch 100%) 4176mV. after 5 mins of non use, it still remains 99% but at 4012mV. with the 1% missing, i guess i can let that go and dismiss as normal now... although i read related thread
http://forum.xda-developers.com/showthread.php?t=866011
and some resetting technique here
http://forum.xda-developers.com/showthread.php?t=921848
but anyway my simple mind would just like to say, "ok its displaying normalcy now".
now i did not figure what caused the tab to display erratic behavior before this, but once i got it i will update again.
The last couple of days I've got a weird problem. When my battery is fully charged everything seems okay and it drains in normal speed (compared to stock).
But when my phone runs out off battery and i start to charge in the beginning everything seems fine.
But suddenly it can go from 75 to 100% in 1 minute.When i look at the stats in MIUI ROM it seems like it's not at same height as it was the last day of 100%. Maybe only 80%.
Sorry for my bad English, but i hope it makes sense.
I've wiped battery stats in CWM. But is it possible that the phone actually is only 80% charged, even though the indicator shows 100% after wipe?
Because if the ROM think the battery is charged and wipe stats it will afterwards only charge to that point and the battery maximum will decrease over days?
If that's possible, how do i full charge the battery? Just leave it in the charger or?
I hope you can understand what I mean.
Thanks in advance

Got the same problem?

have you try calibrate your batt again
yes my friend have this problem too, maybe there is software bug
After flashing Celebration HD 2.0.1b I first used Battery Calibration from market to wipe battery stats. Afterwards the battery indicator problems started.
Yesterday i decided to wipe battery stats manually in CWM and drain to phone to 2% before charging, and afterwards I was able to fully charge the phone.
So maybe the bug in is Battery Calibration app?
I decided to install Juice Plotter to monitor the battery and compare it to one build in in MIUI. Just to get some more data.
Hello again
Yes i had the same problem as you, with my previosly 2 lg optimus 2x, and returned them because of the problem you mentioned. I am on the third op2x and luckily this work good
So if i were in your position i would try to go to the dealer and shift the phone with another lg optimus 2x.

The user said that he started to have problem after a new rom and wiping battery stats, changing phone for that is not the smartest move at all. Is like changing phone because your rom doesn't work.
I have a similar problem, after you wipe battery stats you don't have a reliable indicator, for me the phone took 3 hours to get from 99 to 100%.
I also noticed that my miui ( 1.8.5 same for 1.7.29) doesn't update battery stats when the screen is off so all those plotter don't work, and i think this messes up with the battery indicator (I guess the phone doesn't have enough data to make a decent estimate)
I think is miui + wipe battery stats that can be problematic
I know that but i am just saying that i also had the same problem with the stock rom.

How old is the battery? How many cycles does it have?
I know from laptop Li-Ion batteries that the voltage vs. capacity is not linear.
When discharging, the voltage will steadily drop to a "wear-level" where it will jump to an almost depleted level. When charging, this "wear-level" will be at the top.
Why I am telling this? Because if this mapping is kept in SW and you wiped it, Android needs to relearn it again. So at 1st complete charging/discharging you would see a % sudden drop/raise, but at the next cycles it would be linear with time (although the total time will be smaller than a new battery).
When laptop/phone battery tips talk about calibration, it is so whoever monitors the voltage (circuit in battery or SW) to know were the wear drop will be, so your estimates to be better.
As an example, I had a very old Thinkpad that did not have any calibration, and it would discharge to about 40% and drop to 5% within seconds. But when charging, it would raise steadily to 70% (from that 5%) but 70% to 95% in seconds. After years of use, that percentage gap would just increase (40-5 got 60-5, 70-5 on discharging).
PS: my current Thinkpad has 4 years and the battery capacity is 49% with 150 cycles. But this one has a nice feature where if the battery was above a certain percentage, plugging AC would not charge it (and thus save a few cycles). I used it set at 70%.
PS: LiIon batteries have cycle count, heat and time as main enemies. Also don't like prolonged (think storage) low charge.

The last couple of days I've got a weird problem. When my battery is fully charged everything seems okay and it drains in normal speed (compared to stock).
But when my phone runs out off battery and i start to charge in the beginning everything seems fine.
But suddenly it can go from 75 to 100% in 1 minute.When i look at the stats in MIUI ROM it seems like it's not at same height as it was the last day of 100%. Maybe only 80%.
Sorry for my bad English, but i hope it makes sense.
I've wiped battery stats in CWM. But is it possible that the phone actually is only 80% charged, even though the indicator shows 100% after wipe?
Because if the ROM think the battery is charged and wipe stats it will afterwards only charge to that point and the battery maximum will decrease over days?
If that's possible, how do i full charge the battery? Just leave it in the charger or?
I hope you can understand what I mean.
Thanks in advance
