After successfully booting into android for the first time my battery life in android skyrocketed down, but that didn't really bother me.
The real problem is that even in WINMO my battery life is less than half what it used to be, and even after a night (8 hours) of charging (In a wall socket, not USB) its not at 100%
this has me very worried, any ideas? thanks in advance!
did you read anything before you started this thread...........
yes, i did. everyone is having a problem when they charge in android it gets to 90% then they switch to winmo and within minutes it picks back up to 100%.
this is not the case for me, my battery does not jump back up, it drains quickly even in winmo, and when it gets low its not just reading it improperly it just dies, so no this is not the same problem
did you know there are fixes .......and that your problem is not new at all....i am sorry to say that this is a know problem and you would want to ask in the thread of what build you are using and if you really wanted help you would post what build your using and what kernal , but no one can help you at all when you simply state you have battery issues
drain your battery in winmo till it dies, so the battery resets, then charge the battery again till full, it should be allright again.
thank you dipdap i will try that

I strongly advise you NOT to do so. Draining a Lithium-Ion battery entirely is detrimental to its overall life/capacity. So instead of ruining your battery (or going a step towards ruining it), simply turn off your phone, charge it until you get the green LED, boot back to WinMo and it should be alright. If it isn't, look for another way, but completely draining your battery should not be the method of choice.
nobody said to drain it copletely, just till winmo dies, which should be fine. I do this once every couple of months by accident, and have never had a problem. I agree that you should not drain the battery completely though, so, make sure as soon as winmo dies, plug in to a charger.
what rom are you running? I am using shubcraft 1.5 and mine charges to 99% And I can get a full day out of my battery with pretty decent use.
Are you using setcpu cause that could have a major impact also do you have wifi,gps or bt on. I know gps has been known to cause some major drain while in sleep mode.
There is also a thread where people are trying to find solutions to the high amount of drain in the development forum.
We use current widget to create a log and monitor Our drain. You should be seeing less than 10ma while sleep I usually see between 3-7ma while sleep
Funny how when you are watching your battery it drains faster. When you are watching the clock time goes slower.

You can look at this thread
http://forum.xda-developers.com/showthread.php?t=770903
It was very helpful for me to identify how much current is being used while in sleep mode and active.
Download "current widget" from market and monitor your current supply for 30 minutes during your phone's screen is off.
Yeah with the screen off you cant see any thing but thankfully the log will be written for the current widget every min.
If your current comes out to be bellow 10ma during this time then you are doing good and should last you one day of usage else you need to pinpoint what is drinking all the juice even while your phone sleeps
Read the thread ALL OF IT, it will help you understand better.
Cheers.
alright thanks for all the help guys, the battery drain actually worked although i felt strange doing it, but still my android life isn't so great, i would love for it to work completely though because the only wquivalent option on my carrier is the Captivate (Galaxy S) and that thing is ugly compared to the HD2
such problem
I have such problem with battery drain under WM, after i run and quit android, but i found a solution, just pull out your battery few times next just recharge it and it will be OK .
I have had the ultimate in crappy battery life since day one with my Vibrant. I have tried reconditioning, task killers, freezing apps, etc., etc. Very minimal gains and, in some cases, worse battery life. These things were draining just sitting on our pockets.
Here's where it gets weird. My wife also has a Samsung Vibrant and was getting the same horrible battery life. We were both charging dead Vibrants half way through the day. Granted, we are both moderate to heavy users but I expected more. A week ago, my wife was still sitting at 80% by lunch time while I was looking at 27%. Huh? I asked her what she did and she had no idea except that she had downloaded a battery monitoring app the day before. I thought it made no sense that this could have anything to do with it so I brushed it off. Over the next few days she was still getting killer battery life throughout the day.
So....I decided to give it a shot just to be sure it wasn't that app. Well, just before bedtime, my battery was it 7%. I downloaded the battery app, plugged in my Vibrant and hit the hay. By noon the next day I was still over 80% I have no idea why but I know it's working for both of us and it has to have something to do with this app.
I'm no programmer and I certainly have no vested interested in any android apps. We just stumbled on this and it works. Would anyone out there have a clue why?
I'm not sure if posting the name of the app breaks any xda rules so I'll wait.
Ever since i've been on JK2 Froyo my battery life has been excellent. But i'm interested in hearing which app you're talking about

I agree. I just didn't want to be seen as peddling a product here.
It's called BatteryTime. It's free although, I believe there is a pay version. I didn't adjust any settings. Just installed it, charged over night and I can't believe the difference nor understand why it made such a huge difference. I unplugged 4 hours ago and have 98%. Still a mystery to me but I'm not complaining.
There's like 4 of the same app on the market x)
What is the full name?
OH and thanks, I installed it, I'll report back with results.

Just Looked again and you're right. There are 4 versions there. I'm currently using the "BatteryTime Lite" version.
The only thing that I can think of to rationalize this huge difference is that the battery percentage was being reported incorrectly before. I may have had a charge that would last all day or longer but it was displaying an accelerated discharge rate which would kill my Vibrant prematurely. For one reason or another, this app appears to have corrected that and the indicator is (I hope) reporting the correct battery life now.
Does that make any sense?

Thanks for sharing. I will give it a try.
Update:
I found this somewhat disappointing. I rebooted my phone for the first time in about a week and on boot up the indicator is displaying significant drain again. I was at 96% before boot and 56% after? I'm going to recharge to full again and see if I still enjoy the same battery life.
Now I'm really confused. Sent an email to developer.
judging by the app description and most of the comments - the app doesn't actually *do* anything. It merely reports the battery differently.
No amount of software will change how much charge a battery can hold. The only thing that's different is how it's being reported.

Indeed, and that was my point to begin with. Originally, the battery indicator reported as critically low in no more than 6 hours. Soon after, the phone would shutdown until put on the charger. With this app I am able to get through the day reporting roughly 30% at bedtime around 10pm. Of course, that is subject to change on a reboot....until fully charged again. This is the mystery.
Yeah, there is funky stuff going on with battery meters. One that is included with the Obsidian Roms is Battery Left, currently, this is showing a 50% charge and 10:19 left. Next to it is Juice Plotter which is showing 21h 11m left. According to the system, i am at 71% Power and it has been unplugged for 6 hours. From experience, I know that the 21h remaining is actually accurate and Battery Left is completely dorked.
The point being, you can't always trust the battery meter.
So I installed a monitor also to try and figure out what was killing my battery 30+% over night and I had the same reaction....I woke up to a 10% loss. I realized what is probably happening is since this app is monitoring the phone all night...whatever app is draining the battery is probably a daemon that only runs when the CPU goes really idle for a certain period of time. More than likely that app inadvertently gave you better battery life because it runs in the foreground and marks your phone as being active so whatever app was killing battery never ran.

I think you've hit the nail on the head. Since day one, I have had buggy battery reporting. For instance, if I reboot the phone while it is plugged in, the reported battery level changes dramatically.
Edit: your later post supports this idea even further.
I installed this on my phone. This program does not attempt to save battery life or control anything on your phone. It does offers "Tips" to save battery life. Its main purpose is to indicate, based on your current level of charge, how long your battery should last given different circumstances - ex. idle, talk time, video time, audio time, etc... Thus the name BatteryTime.
That's all that it does. Any perception of a longer lasting battery may have been an anomaly as does happen sometimes with our phones. One day you'll seem to be getting awesome battery life (and there is likely an underlying reason which we'll never figure out, but which jives with the battery) and the next day it is back to draining quickly as normal.
There are three certainties in life: death, taxes, and posts about battery life in smart phone forums.
Anyone have the issue where they charge the phone overnight, the phone reads 100% in the morning, you unplug it and you are immediately down to 7% battery? It seems to happen to me at least twice per week. It is a terrible bug.
i dont get it you said that before the battery wasnt being read correctly so it shut off fast but now with the app it reads correctly and last you the whole day with 30% left to spare?? wouldnt that technically mean it increased battery because you got it to last all day plus some? just by making the phone read the battery correctly.
I am aware that there's already a thread that is related to the tablet/dock battery drain. But I thought I'd make a poll to get an overview on the number of dock owners that are affected by this problem.
This thread is not meant for general discussion of the topic, for that please post here.
Even though the battery draining issue is also remarkably high when in standby, please vote only for bundles that drain when they're completely shut down! This will help to exclude every bug that could be software or ROM related.
Where are the over a week or 1-2, 2-3 week options?
I don't think my drain is out of the ordinary. I have a had a couple of programs run rampid and kill the battery but it seems OK. I would like to know how to tell the battery state of each? Also I would say that when charging the dock/tablet combined the charging brick gets really warm.

Well, I don't know but I'd call that no unreasonable battery drain. Or do you think this is abnormal?

That's why I only want to list the devices that drain when completely shut down So no apps can run rampid.
To show both of your battery states, use Dual battery widget (also available at the market).
About the warm charging brick, I noticed that too, but I'm not too concerned since I owned a lot of chargers that got this warm while charging...
I'm grabbing the Dual Battery widget...thanks for that tip. I'll check with a full shut down.
I know there was a recent Google announcement regarding battery status wipe, however, I found the results otherwise.
Seems that many individual now trusted official Google's spokes person, I would like you take you back on our side regarding the battery reading issue.
Another reason for this post is to make sure all the ROM flashers out there understand that it is probably not the ROM's fault but the battery meter is off. On top of the above, due to the fact that recent comments to all the ROMs has been "battery for this ROM is horrible" or "This ROM has awesome battery life!" before they have fully tested the entire battery cycle.
What Google is pointing out is not necessary "wrong" but it is misleading. They are implying that users are considering the Li-ion batteries to have "memory" effect like NiMH, yes, some users may still believed so. However! To fully "wipe" the battery level, you must understand that the Li-ion crystals inside the battery does not have memory effect, it does have a "meter" that reports the battery status. This meter is used to make sure all the cells in the battery is equally consumed properly, but during a ROM install, CWM restore, these values gets confused from time to time somehow in the software level.
Now, you must think that I have no facts to say Android OS is responsible for controlling that meter's data, but my experiences has proved to be convincing.
A simple example for the case to be more clearly explained is something what I have experienced before. After new ROM installs or CWM restores, I have the following experiences regarding the battery percentage reading.
Case 1: Battery lasts almost another hour with screen on with ONLY 1% left.
Case 2: Phone turns off without reaching 0%, sometimes as high as 8% my phone turns off.
The above 2 cases happens usually when the new ROM is installed and usually would have a battery reading far off from right before the ROM install or restore. They usually result in battery not being able to be appeared fully charged or in some cases in CM9 that the percentage goes above 100%
I hope the above has convinced you that "battery wipe" is necessary from time to time or cases to cases, also note that pulling the battery when the phone freezes sometimes would case the same issue.
If you are convinced, you may use the following steps to "wipe battery status" or "calibrate" is more precised term here:
Run the phone until it turns off and cannot be turn on
Plug it into a wall charger and ONLY wall chargers (because computer USB ports will boot Atrix)
Wait until the big battery charging animation reaches 100%
Boot into recovery and wipe battery status
Reboot the phone
You should now have a "calibrated" battery meter at a hardware level where Android OS was not interfering with the meter AT ALL . You might be able to charge to 99% at most of the time, but that is fairly calibrated, can check if the voltage is at 4203mV to be sure.
My battery when on cm7 won't charge past 4196 but if I flash miui it hits 4204,it's weird.
One thing I do to is before and during flashes I make sure I'm at 100% and still plugged in on the wall charger. This helps alot.

Not trying to pick a fight, but I just wanted to point out that what they say regarding battery stats isn't misleading. Batterystats.bin and "battery status" are not related. The battery stats that everyone wipes in CWM are exactly what the Android Engineer said they are, usage statistics for battery consumption by apps. (which always get wiped any time you reach a full charge) Batterystats.bin has no effect on what battery life is being shown.

The battery reporting over 100% in CM9 was a kernel issue (checkout this commit). If you browse through the entire file for that commit, you will see the battery % reading is also handled there (search for battery_state), and you will see it's tied to the battery reaching 4200mV.
-----------------------------------------------------------------------------
Other than that, thanks for trying to clarify the "horrible battery" problem people always seem to think they have. Yesterday I saw someone asking about battery life 20 minutes after Notorious updated Neutrino, lol.

haha yeah, i say that comment lol. I said it was misleading for that fact you stated above, but my point was to tell how people can fully recalibrate the battery first before considering roms have bad battery usage. Because people now thinks that android os has nothing to do with the bad battery.
Interesting for the ICS battery issue... i was able to get it to 99% and 100% when i do the above cycle though, no more > 100%. but it is good to see it has been worked on

i try he method from the first post , and i feel mybattery is lasting longer than before i just let it die at 7:53 am from today , connect the wall charger, let charge full, because i don´t have CWM recovery , i used battery calibrator from the market to recalibrate my battery
at 8:32 pm from today with a lot of whats app facebook some games and call etc im on 70 %
thanks for the TIP !!!
Battery calibration, galaxy tab 2 CM9CM9, and at first glance it seemed that the battery was draining way too fast.
So after some research, I found a solution to this problem. When I had the stock rom, the battery life was like 15 hours, all day wifi on. But when I moved to cyanogenmod 9, the battery life dropped drastically to about 6 hours, minimum brightness levels. So got back to stock. Soon I was missing CM9
Suddenly came to my mind that maybe the problem wasn't CM9, since I have read that many people is very happy with battery endurance.
When we flash a new from, the battery data remains intact, this sometimes causes the new rom to have a bad reading of the stats.
The solution I found is battery calibration. You can find an app for free in the market. What it does is, it wipes your battery data so the new rom generates fresh data.
You just have to get your GT2 fully charged, then calibrate with the app.
Since I did this, I feel battery life has improved, in fact, I think it is better than before CM9.
YOU SHOULD GIVE IT A TRY.
it worked fine for me. :laugh:
sorry
The post was right before sending it.
Tried to attach a pic, but I'm new here guys
Battery calibrate only deletes the existing battery usage data. It gives you a fresh look at what is draining your battery. This has been argued many times in just about every other device forum. Here is the answer from the google rep.
