[Q] The battery is drops suddenly on Galaxy S2 - Galaxy S II Q&A, Help & Troubleshooting

After I fully charge the phone, and disconnecting it from the power, the battery suddenly drops to 96-97%, it is normal? I already made a battery calibration past week. Even after I upgraded the phone from XXKG2 to XXKG6, still the same problem here. I bought the phone last month. (by the way, it is rooted and I have on it the 2.3.4 stock)

Post some pictures of the battery usage.
And also some of bestbatterystats.

Try this: After you get the "Fully Charged" notification, try not to take it off charging immediately. Leave it on there for about 10 minutes or so and then take it off of charging, you should see it as 100%. If this does not help. Please post some screenshots of your battery usage screen, we can troubleshoot from there.

This is the stats for the moment dropbox.com/s/4svvwpevod8cmm7/SC20110828-000603.png , I just installed the Battery Monitor Widget, to see whats the deal, for the moment OS and Display is drain my battery, because I have played with the phone for about a 15 minutes, but during the day, OS is always on 10-15-20% and display the same

Tap your finger on graph above and screenshot that.

Did you calibrate your battery, before or after you upgraded to KG6? If you calibrated it before, then you should try calibrating it again.

1. Charge 100% (best way switch your phone off)
2. Run Battery Calibration
3. Drain the battery until it's totally empty.
4. Charge again 100% (best way switch your phone off)
5. Reboot and enjoy

No I did not calibrate it after the upgrade, but when I was on the XXKG2, I calibrated it 3 times

Yes. It's exactly that.

I think maybe batterystats.bin was not removed, I tried to remove it with Battery Calibration app, but I didn't checked if it was or not. Tommorow or on monday I will try to post some stats from Battery Monitor Widget

That does look very much like a non calibrated battery. Try calibrating it as 'Bruaca' mentioned, and you should be getting the correct readings this time around.

I did another calibration, with the device turned off until battery riches 100%, then I turned it on, then I removed the charger, and it was on 100%, I put the charger back, again after 5 minutes I heard the signal, then I went into Root Explorer and deleted the batterystats.bin, and pulled the charger, now I have 100% + 4143mV, it's normal? or should be more mV?

4143mV sounds a little high. Mine is ~3600. Though I'm getting the opposite problem. What might happen is that I'll leave it on overnight and it'll gain 2 or 3 percent of the battery. I started getting problems charging after I installed font changer, which was also weird. Like, it'll take ages to charge to 100%.
Edit: 4143mV sounds about right for a fully charged battery.

[Q] Battery Bizarreness

Yesterday, I let my battery die. Charged it last night, and wiped battery states. Ran the phone like normal today. Was down to about 30% left, rebooted. When everything came back up and running, that battery showed to be 5%. WTF!!! How do I drop 25%, just by rebooting?!?!?!?

I re-wiped the battery stat this morning. I was down to about 50% when I needed to reboot. When everything came back up, it showed I was down to 28%. Is this an indication that the battery needs to be replaced or should I try a different Kernel?
Either you have a bad battery, bad battery meter, or your not reconditioning right.

What would you suggest I try? What is the proper way to recondition my battery?
Charge to 100%
Boot into recovery
Wipe battery stats
Reboot
Don't unplug charger until at desktop again (You could debate this one, but that's when I do it)
And don't worry about killing your battery, it'll do more harm than good.
Explanation - When you wipe battery stats, it tells your phone you're at 100%
So, if you wipe when you ARE at 100% you'll get accurate readings.

The past 2 times I did this, the phone was turned off and plugged in and charged over night. this morning I wiped the stat, but i do not remember if I had unplugged it before it finished booting up. I am charging it now, with it on. When it reaches 100%, should I reboot into recovery and wipe it or should I let it run all the way down?
What exactly do you mean by 'let it run all the way down'?

Down to say some were around 20 - 5%.
As far as I understand that shouldn't be necessary, and could weaken your battery.
As long as it's fully charged when you wipe the stats you should be good to go.

Ok...I have ran the phone like normal. Within 6 hours, I am down to 62%. I rebooted the phone, and it still shows me at 62%. At least I have that fixed.
Now, I see some people use OverStock and seem to be getting better battery life. I just want to get about 16+ hours out of my battery. Right now i seem to be pushing 12 hours. What is the tick that i am missing??
For every hundred vibrant users there seems to be a hundred different accounts of battery life, and a hindered different opinions on how to keep it down. 12 hours on the stock battery is pretty good, especially compared to stock.
Mine'll last me around 15+, if I left it not charging, i think.
I'm on overstock, the screen is at the dimmest 95% of the time, and I use setcpu. 1000/1000 with a screen off profile of 200/200. So, that works for me pretty well.

You need to recondition yr battery as posted above, 2-4 cycles. But i prefer to re-flash ROM when battery 100%, should you get proper batt stats.
You may buy new one to test yr system n batt stats, also good for spare. Or just borrow yr friends battery, just to check yr rom n batt stats. Treat it like you did before.
Good luck.

200/200 conservative scaling and no sleep death? Didn't know that was possible on overstock...guess I'll try it.
Edit: sleep of death...you must be on power save or something which afaik doesn't work at all.

Yeah, powersave. What's this about it not working? It occasionally lags a little when I unlock it and the widget definitely says 200

I don't think powersave is supported...try conservative and you'll get sleep death due to the low frequency...you don't get this with powersave because I don't believe it's working...trying to confirm this.

battery won't charge past 96%

Hi guys, I am at my wits end with this stupid phone, If its not one problem its another. I was convinced this phone would have amazing battery life once seeing my cousins AT&T version, I bought the UK T-mobile version and its been plagued with faults. The main fault it has developed now is that it won't charge past 96%, I have configured the battery and installed the 1% battery fix and nothing is happening also my battery has been draining quicker than usual. Sometimes I get 13hrs sometimes I get 7hrs!? Could someone give me some advise? I was thinking of ringing my insurance company for a replacement (as it is with my bank and usually they just replace the phone)

I'm sorry, are you sitting in front of my phone? I have followed this correctly on another atrix and it has worked for them, I don't know why its not working on mine I have followed it through properly.
How long have you had the phone?
One thing we all have to consider is that since the dev community has had to provide "fixes" for the Battery Reading on the Atrix it might be safe to say that at some point the measurement might become too accurate. What I mean by this is, I've had my phone for almost a year now and I'm pretty convinced that the reason my battery won't charge past 97% is because of the natural degradation of the lithium battery. It is a fact that lithium batteries can lose up to 10% of its charge capacity after a year. So I've accepted the fact that my battery just might be losing capacity and the battery mods I have applied to my phone are just that much more accurate.
This reminds me of the recently released Galaxy Nexus and people complaining about the signal and Verizon responded with that the "reading" was too accurate and that they'll release a patch that will basically "lie" to the end user about the strength of their connection.

Verizon is just basically saying "Here, let us cripple your phone for you"

I have had the phone for about 3 months now. This is why I am saying its weird. The fact that it dies so quickly is another thing I got about 7 hours of moderate use with about 1hr 45 display time with 10 mins of music and about 10 texts and a few phone calls(about 3 short 5 min ones)l
All of you are talking percent. What is the power level of the battery at max charge? Battery showing charging to 100%, or any other percent, and having full charge are not the same thing.

Could be a faulty battery. If you've only had it 3 months I would try to get the battery replaced if it has drain issues.

The battery never reaches 100 on the phone it will sit there at 96% and even the battery calibration app says the battery isnt at 4200mv (which apparently it should be) its at 4190. I never charge mid way I always let the phone get to about 15% then chuck it on charge.

Well I use the internal android one but I want to know whats draining it because today nothing was running, i had everything shut down and frozen that wasn't necessary.
You might need to use a 3rd party app to find the "rogue" app/process. Other than BMW, I also use System Panel to monitor it if I notice my usage time is depleting, it works well. You have to have monitoring activated and it's only available on the paid version, but you can use the free version to manually watch your apps/processes.

Ok so I recalibrated the battery and got rid of the 96% freeze but now the drain is quicker than ever :S
have you tried wiping battery stats as well? Also, when you recalibrate, do you go through a couple "full" charge cycles? As in, do you allow the phone to fully discharge and then completely charge it plus at least an extra hour? I know that lithium batteries do not have the "memory effect" but I think it has more to do with software rather than the battery itself.

yeah i do wipe battery stats but the mAh is not going to 4200 its stuck at 4186 nd wont go past 98%
Something else you could try that I've read around here.
1. Charge the battery for like 4 hours until it won't charge anymore.
2. Unplug the phone from the charger, turn it off, and then pull the battery out
3. Plug the phone back into the charger (Do not put the battery back in yet)
4. Wait for the phone to show an image of a battery with a question mark in it.
5. Put the battery back in.
6. Wait for it to recognize the battery, it will probably give a very low percentage like 5% or 10%.
7. Do not turn it on yet, let it charge for another hour or so.
8. Once you return, it will still probably show a low battery reading, ignore that and boot into recovery while it's still plugged in by long-pressing the power button and when you see the green led notification light press and hold volume down
9. Wipe battery stats and then reboot.
10. Wait for it to boot and then unplug it from the charger and check the battery reading.
I really don't understand what this does but I've read it has fixed the issue for some people.

[Q] Can't charge beyond X%. (Yes, I've searched!)(Yes, I saw Dianne Hackborn's post!)

Hopefully I can state this in a way that doesn't scream "I don't know how to use teh search!"
I calibrated my battery stats using the free app on the market after flashing darkside. My phone used to charge to 100% on the indicator (4200+ mV). Now, a couple of weeks later, it charges to the same 4200-and-up charge but the meter tops out at 92%. Two days ago, it was topping out at 94%.
I've re-calibrated using the app, draining it down and charging fully up. Same result, 92% max.
I've wiped battery stats using CWM immediately after charging fully (verifying the charge is above 4200 mV). Rebooted. Still at 92%. Actually, now it's reporting 90% with 4128 mV.
so if wiping stats is a "useless operation", what gives? How is it possible that this method apparently fixed other users' miscalibrated battery meters stuck down around 30-40%?
Try this:
1. Charge as much as it will charge
2. Turn it off and take out the battery
3. While the battery is still out, plug it in and wait for it to show the battery image with the question mark
4. Put the battery back in (do not turn on yet) and let it charge for an hour
5. After an hour, turn it on, unplug, and report back
Note: On step #4 when you put the battery back in it will probably only show like 5% or 10%, just ignore that and let it charge

Bump charging now. Will report back in an hour
.... all right, got impatient. Pulled it just now; 99% on 4158 mV. That's better. Many thanks!

in cm7, charges to 98% normally, but sometimes takes hours to reach 100%.
I hope i'm not hijacking this thread, but since we are talking about mV i thought this might be a good place to ask....
I've been having problems with my battery levels for a while, i've tried all the voodoo to try and fix it but i can't get anything consistent.
here is what i get....
i have battery calibration app installed, sometimes it will read 4200mV and be 20% charged. Other times it will read 100% charged at 3700mV, it's all over the place, and trying all the suggestions to fix the battery life don't seem to fix it.
another thing i have is it will discharge from 100% to 5% within an hour but my mV will be at 3900+, then it will sit at 5% for another 8+ hours then the phone shuts off, so i plug it in and it says 5%, i let it charge for a minute or two and it's at 20%, i turn it on and it shows that it's above 3700 or 3800mV.
so the phone thinks it needs 3700+ mV to run, but not always, sometimes it will go down below 3600mV and still run
A couple questions
1. can someone post their mV reading at 5%, i'm guessing it should be about 3300
2. what is the max mV that you have....is it above 4200mV (mine never is)
FYI information i've tried fastboot -w, cwm battery wipe, deleting the battery stats file manually, even formatted /system and other file systems to make sure it was fresh

Ok,
I did this and my battery starts off at 100% and all appears to be fine. The next time I charge, it only shows 83% and it is reading 4200mV which should be a full charge. Do I have to do this each time? Is there any other solution? I am running CM7 stable and the battery is an aftermarket one. Could this be the issue? Thanks in advance all.

One trick I've found is unplugging the micro-USB and plugging it back in immediately. When I do this the 4200mV usually drops to the low 4100 range and the % continues to increase.
Only caveat is you'll have to keep doing this until it reaches 100. It takes a while since it seems to get re-stuck at every 1-2% intereval. A pain, but it's a work around from having to pull the battery. :silly:
I have the same issue too but DO I ALWAYS HAVE TO DO THIS METHODS? My battery level drops day by day (becomes %92 max) from %100.
I'd had the issues you explain for AGES.
I'd heard that buying a new battery wouldn't help. But I bought a new, official battery off eBay and I've not had the issue since. That was a couple of months ago now... not saying it will definitely work but at worst you have a spare battery...
What works for me... Charge up as much as possible, then use root explorer and go to data/battd/ and delete everything except the file "uid" then reboot... Should be good to go...
Hope this helps!

This definitely worked for me. I was having repeated issues that full charge/drain calibrations didn't fix. This did.
I had the same issues with charging it ,but i foudn out that the only failproof method of chargin it by using the oem ac adapter and the oem usb cable if you dont have the cable the nokia cables shoud do the trick but the samsung one does not work i dnno exactly why but i tested it myself.

If I keep my phone on charging even after its on 100%, it starts rolling back. As in from 100 to 99 then 98, even if its pluggen in.
Don't know what kind of a problem this is, hardware or software.
Or there's some issue with the battery.
Please help.

Sometimes I have the same problem. I dont know if it is caused of a program running in a background or what, but reboot helps

I know the reboot helps.
But usually I put it on charging at night before sleeping.
And when I wake up in the morning, the battery % becomes even less than what it was when i plugged it in.
I'm usually in a hurry then to leave for college in the morning . Can't go to college with battery % less than even 10
Thanks for the reply anyway !

Maybe You have some program that syncs something all the time. Did You try to turn off data and wifi. You can always check it if the reason is the hardware or Software. Just make a backup of Your whole ROM, delete the data and leave the phone over night. I hope it is only software problem.
EDIT: Does Your battery go hot while charging? Oh, and try to wipe battery stats

Yes, my battery does get hot while charging.

Maybe there is really some program that is causing that. I had this problem rarely so I never cared. I had one program called Batterymonitor or sth. like that and it was the reason. Do You have such a program, that shows Your battery level or temperature?

Yes, I have setcpu and rom toolbox.
But would these applications really cause this problem?

The x10 charges the battery to full then if still plugged in it will stop charging until batt drains to set level ,then will charge to full again and over and over all night. X10 wont over charge batt when left plugged in. Kernel/bootloader handle this. There is an app current widget that can log charge levels.
EDIT: I had a tip on charging here but removed it after further research read more about batt here..

EDIT: the best tip I usr for battery life is, let batt runout until phone shuts off, then pull batt, then plug in charger, then replace batt into phone, then phone will boot, enter xrecovery on first boot and wipe batt stats. After wipe while still in xrec pull batt then unplug. Now plug in phone then insert batt. Phone should boot in charge mode( big batt icon only on screen) dont start phone untill light green for 1-2 hours to get full charge . I do this about once a month, when phone starts to shut off around 15%

As mentioned above as well, this is normal. After charging to 100%, the phone stops battery charging, and will activate charging again only when battery falls a bit (say 97%). Also, battery heating while on charging (and also when using the phone continuously while playing a game) is normal. Relax.. your phone is fine
@ToledoJab
I am having the same issue with battery... phone switching off at 15%, even at 22-23%, when playing a game or something. But switching it back on, and leaving it idle, phone might run for another 2 hours. So it is the extra load while running a game that the phone cant take any longer (i remember getting the 15%,10% and 5% reminders earlier while playing games)...? Does the battery calibrate method actually help in your case? does it go all the way down to 0% or 1% before shutting down.. ?
I just did this after posting that. And yes my phone reported warnings @ 25% 15 10 5 and then shutdown @ 1%.
This way is like reconditioning an old rechargeable ni-cad batt.
All this does is completey drain batt then, with least amount of drainage (phone on, apps& radios running) allows battery to full charge.
There is also a way called recalibrate battery. But this way over charges the batt.
EDIT: I think the phone load will effect reported batt left. I think batt gage use average loads to estimate remaining power. Meaning games, full brightness of LCD, radios -3g -GPS -WiFi -Bluetooth will use more than avg power
edit 2: I found this thread also has some very good points and links. after reading this i will not intentionally take my batt to 0%. I hit 0% about 1-2 times a month on accident as it is. i will just make sure when i do go 0% to wipe stats (dont know if it helps or not) then preform a long (overnight) full charge with phone off.

SORRY for ranting on about this, i thought i was smart but i am still/always learning.

Rom/Battery

Having issues with roms lately. Some roms won't even give me 2 hours of battery life. (Maybe 4 hours even in standby!!)
Talked to Motorola over the phone they think maybe it's the battery, they sent me a free one but I still have the same issues.
Sometimes I look at my phone and it has already been drained. Then I see that standby has taken up 75% of the battery. Like wtf lol.
So the question is, what is the best ROM for battery life?
Thanks.
Neutrino v2.9
Make sure you install bluesleep fix if the rom you are using doesn't have it....
For me the best results have: "old" ALIEN and CM7 !!!
CM7 - 1day and 27minutes with 7hours and 28minutes screen on (30-35% luminoziti)
Sorry for english!
Atrix - "CM7"
Seeing as it happens with every ROM, you may try to calibrate your battery, it may help. Download 'Battery Calibration' app from the Play Store and follow the in-app instructions. I always calibrate mine after changing ROMs exactly because problems like yours happened to me in the past.

That app does not calibrate the battery. All it does reset the previous battery usage graphic table.

But it helps. If I don't do it, after 2~3 flashes of different ROMs I start to have huge drops (staying at ~80% for 6 hours, then instantly dropping to 20%) or the system misreads the actual battery capacity (turning off with at least 30% battery remaining, for example).
Have you tried wiping battery stats?...
Charge the phone as far as it will go (lets say over night)(also if you need to plug the phone into the charger after it has charged over night without the battery in it so you get he battery with a question mark, then put the battery in and it should show like 5% battery or something then let that charge as long as it will, which is usually around 15% if i remember correctly), then wipe battery stats in cwm or whatever way you prefer. Reboot the phone and use it until it is completely dead (0% battery and the phone shuts itself off and wont turn back on, but do not try to drain the battery using video loops or anything, just use it like you normally do. Then charge it up to 100% but do not turn it on, let it stay on the charging screen until it gets to 100% and dont use or unplug it at all. It should take longer to get from 99% to 100%, just be patient Hopefully that solves the issue.
