Here's my problem:
My battery level suddently drop from 50% or 30% to 0% in few seconds.
When i'm in system on (for example) 90% battery, if i go in recovery my battery level is 5%.
I tried a battery calibration program with no results.
My last chanche is to try another kernel but, i can't find one!
I'm searching for a stock kernel with root and recovery for 5.0.1.
Now i'm on rockz1 kernel.
Someone know where to find a stock kernel that i can try without losing root?
Or maybe there is already a solution to this strange battery problem?
Sorry for this noob request.

There is nothing strange about this problem. You have classic symptoms of a dying battery. No kernel, rom, battery calibration or any other solution will help. Replace the battery and your problem will go away...
The reason your battery goes down suddenly is that it can't hold power due to deterioration of cells. In other words, only 5-10% can hold. Think of it as an air baloon: your baloon can hold 10% of air it used to hold and it will still rightfully show 100%, but once you start using it, the air goes fast and once it is close to empty, the system shuts down the phone. I bet it does not also take long to charge for the same reason.
If you don't believe me, do a test: start a youtube video when your battery is at 50%: I bet your phone wouldn't last more than 15 minutes.

Hi
Got an extended battery for my G1 a few days ago from ebay.
The problem is, the phone doesn't recognized it after I switched the battery. I had the same charging % as the previuos battery right after I changed it (even though I never charged it) and the max use time in Battery time lite is the same....
Any ideas ?
Thanks,
Nati
bad phone ? my ext batterys work fine from ebay
is there any way I can be sure ?
Maybe it a firmware thing ?

I had similar issues when I first got an extended battery (Seidio 2600mA). After performing the steps below, I had no problems at all. I hope it works for you.
Try a COMPLETE drain and recharge cycle, a couple times.
Run the battery down until the phone shuts itself off, restart the phone and let it run until it shuts itself off again. Repeat until it will NOT boot anymore. This will take a surprisingly longer time than you think. Load up your music player, youtube via 3G, etc... kill that thing.
Once the batter is so dead that it can't even load the splash screen for a boot charge it up, but do not turn it on. Let it charge up to full for a few hours (usually four will do it) and turn it on. If it's not at 100% yet, let it charge for a while longer. When it's at 100% take it off the charger and run it down again like before. Run it until it is totally dead.
After a couple cycles like this, you shouldn't have any problem with your phone and battery giving accurate charge status results and operating as it should.
I've read, from a few sources, that between the internal monitoring on the battery works, and the way the G1 reads the battery state, that this complete drain and recharge cycling helps to establish baselines for "empty" and "full" and keep them synchronized. If your phone has never seen an extended battery and the battery was at partial charge when inserted, it may not have been able to accurately gauge the minimum and maximum extents and give faulty readings based on prior battery data.
That could be wrong, and I don't know for sure. But, a complete drain and recharge never hurts anyway, and in my case it actually seemed to solve the problem for me.
Good luck!

using any mod, (cm9, darky, slim...) the situation is the same:
My battery would be on about 95% when I take it off charging overnight. But after some minutes it is around 85% or 80%.
battery usage is ok usually, drops a lot if I use it a lot with full brightness, etc, all ok.
But the issue is that sometimes the phone turns itself off. when I turn it on, it says anything from 10% to 1% battery left.... and then it INCREASES slowly. For example, if it happens and I see 5%, in a few moments it says 6%, then 7%, etc, and might go up until 40% or more.
I do not know what the issue is and have not find any indication of this problem anywhere.
thanks.

all the rom's you flash you used the same kernel?

No. Devil, Semaphore, and others.
By the way, another issue: if it's in the low % stage, say 5%, and I drain it hard to 1%, it turns off. but even after reboot it still keeps going up.
That means the juice is not empty, because an empty battery would make the boot itself fail.

try cleaning battery terminals and phone terminals, and if you have dropped your phone a lot try putting a thin bit of card at the base of the battery when you insert it just in case it's loose/bad connection

Don't keep more background processes.....use slim ics with seamaphore kernel...it has best battery backup....
use apps like advance task manager and try to keep ram clear all the time.....

Good idea. But I don't keep any apps open almost at all, my ram is usually all clear with more than 100mb free. I mean, my phone is usually app-less. as I said, battery level is maintained very well except that it starts at 80-85% and sometimes drops to 10% after shutting down for no reason and then climbs slowly, as if to the level it was before shutting down.

This seems to solve the sudden death and rebooting with 10% battery issue.
However, how do I solve the issue of starting the day with 85%-90% battery? it won't charge beyond that. Calibration never helped. (calibration requiers draining and then waiting to 100%... but I can't reach 100%, maybe that's why it doesn't help?)
battery health registers as "good"...
Anyone ever heard of this? What the hell is that about?
Thanks
Happened to me all the time.
Sent from my GT-N7000
Has happened to me many times on both phones. I'm guessing battery calibration goes bad and when reboot it tries to adjust. Also note that when this happens, battery will slowly recover as if the phone is charging. Say it dropped to 10%, leave the phone aside after the reboot, battery will increase to somewhere around 20%. I've had this problem on the stock ROMs of both Note and the SGS II. Hope this helps.

Try calibrate your battery by letting it blackout then take out your battery for two minutes then put it back again, dont reboot yet, let it charge to full, then go directly to CWMR and wipe battery stat and reboot.

same here, happened to me a few times.
Does battery calib really work or its all a myth??
I don't know to consider this a bug, or what.
But.. battery calibration won't help. I've tried.
On my device, it happened :
*) when my device got very hot (when use certain kernel), I reboot, then voila.... the battery drop around 20-30%.
At first I said WTF... then I faster charge (because at that time, after drop, my battery left only 1%)
The next time happened, I was on the road, and can't charge my handphone. So I just leave it there, laid in my bag.
Surprisingly, after some times, the battery start to increase again, though it's not coming back to the same percentage as before it drop.
So is it a bug ? Perhaps... but only happened when your device got very hot.
And when your device is very hot (under certain kernel), and you never reboot / switch off first, you will see that the battery flow like water.
But when you switch off, let it cool, then boot up again, the battery will stagnant at the same percentage when you switch off. Go up and go down at the same percentage for minutes to 1 hour+.
So you want to consider this is a bug ? perhaps, but.... not everytime happen. So long as you are on the correct kernel that suit your device.
:victory:
Huge drain may affect the stats.
The percentage is calculated based on the voltage of the battery. On heavy drain the voltage may drop unpredictably (for the ROM). Also, the temperature will affect the voltage (thus percentage).
With my phone if happened only once, the night after update to LRQ so I assume this is connected to battery stats.
But also, certain ROMs can affect this behavior.
Hello!
I am presently on GamerzROM based on GB 2.3.6 XXJW4 Semaphore 2.7.4bm. Problem is that whenever I restart my phone for any reason, the battery level falls drastically. For example, if the battery level is 70%, after restart it goes to 10% or so. Later it starts going up slowly but only goes up to approx 50% of what it used to be before.
I even tried calibrating my battery a couple of times but the problem is still there. Why is this happening and how can I get rid of this?
Thank you.

Try removing your battery for a while and keep pressing the power button when whiles it removed. and then put it back and see if the problem resolved...

Tried it but the problem is still intact... Battery was 66% and after following what you said, it came down to 9% after restart
sometimes it happens same on my sgs
it happens to me sometimes. mostly after flashing the new rom and this issue always solve by use the phone in couple of battery cycle.

calibrate your battery search xda or use battery calibration app on android market
Our phones battery gauge chip sometimes goes crazy when you reboot or flash something. Try to use the phone until 0% of battery and it shuts down then charge to full and calibrate. It should work.

wipe battery stats and then calibrate battery. there's a whole official thread for it somewhere in the forums.

This is the only actual solution. I can't find links right now, but it has been proven and confirmed by android devs several times that wiping battery stats has no effect whatsoever on actual battery performance or visual representation.
Sent from horseback.
I'm aware that this problem has happened to others, and I have seen solutions for this problem, but every fix I've come across works temporarily...and by that I mean a day or two.
While using my Atrix HD, when the battery reaches between 20-35%, the battery will suddenly drop to 0% and shut down. This usually occurs when I am using an app, such as MixZing or the camera app. Any attempts to turn the phone back on cause it to shut off again as soon as the boot animation finishes. The only way to keep it on is to plug it into a charger, and when it does boot, the battery shows the same percentage it had when the phone conked out on me. I've even tried calibrating the battery using NèMa's Battery Calibration app, and the problem still occurs...mainly because I can't get the battery to drain completely so I can properly calibrate the battery.
Long story short, I need a fix, or at least a suggestion as to how I can keep this problem at bay. Does anyone have information regarding this problem?
did you ever wipe the battery data when you flashing a new rom ?
I think you need to re-reconigz the battery .

Agree. In cwm there is an option to wipe battery stats.
I had a similar problem with my HTC First where at 25 % it would go straight to 10 an then to 0 in like 30 seconds...although that was on stock rom...

I don't use the eb40 mod, it's all stock hardware. Haven't tried wiping the battery stats, though; can't believe I overlooked that. I'll give it a shot and see if it does the trick.
EDIT: CWM doesn't seem to have an option for wiping battery stats for this phone; I've tried three versions and none of them give me that option.

I suggest you first write down the current battery volume , for example , now in the system ,you can see 60% battery left .
then you shut down the phone , connect your changer , the phone will change and the battery volume show . if this volume is not equal to the No. you see in the system , it means that your system have a wrong battery data record .

Shut down my phone, battery was at 91% (had charged it overnight). Plugged it in and the charging screen showed 90%. Is that what you were talking about, with the two battery volumes not being the same?
I think it's fixed!
I did a full system reset (including formatting the system, which I apparently had yet to do throughout all this time) to install a new ROM. Today the battery drained all the way down to 2% while I was browsing the web (something that normally would shut off the phone at around 30%) before shutting off. It seems that by skipping that crucial step, the system could not properly read/calibrate the battery when installing a new ROM, which may have caused this problem.
I think it's safe to say it's fixed. For now, at least, but I'm remaining optimistic. Thanks to everyone who pitched in with an idea or just said a few words; great to know people care around here.

I'm glad that you fixed it. I did the same but I still have that problem. When It's 20% it drops to 15% and then to 5% in 30 seconds.

Thankfully, I haven't had it drop that low that fast. Of course, this IS the Atrix HD, which carries such a weak battery compared to other phones in its class. Nevertheless, I feel great knowing that my phone doesn't shut off so unexpectedly. If it happens again, I'll do my best to deal with it, but for now...it's just success.
I had this problem after i force rebooted my phone, it got stuck at 1% when charging for almost 15mins. I had to turn the phone off.

for my understanding ,before you shut down the phont , you saw the batter volumes in system is 91% , and then you shut down the phont ,plug it in , and see the battery volume is 90% .I think in this situlation , the battery record in your system is correct ,cause 90% and 91% almost the same . I think your battery is dying , you should replace your battery

Well, a couple weeks later and I'm still not having the problem. The battery does still drain relatively fast (I go from 100% at about 9:00 A.M. to 35% at 3:00 P.M, with minimal usage such as checking Facebook/Twitter and stuff like that), but that's mostly due to the small battery capacity. The battery health is still good according to the scans and hardware checks I've done. I may, however, look into trying the EB40 mod if it means the battery will last much longer.
