[Q] weird issue with battery

my phone is ARC S
most of times when battery percent is about %40 suddenly the low battery message appear and show %1 and phone shut down .
i'm sure it's not %0 battery problem (double checked with log and this forum guys!)
and tried most of roms and kernels and no different .
is it from battery and shoud i change it ?

try this battery calibration app. if still same problem occurs, maybe it's really the battery itself got problem.
I personally always do calibration of battery whenever I switched ROM.

I think so too.
Battery calibration apps offer a satisfying placebo effect on battery life.
But when battery acts this weird, you need something more than a placebo.
First you do a Repair with SEUS and if the problem persists, it's most probably hardware related.
If one of your friends has an Arc, you can exchange batteries for a day, to make sure that your battery is actually faulty before buying a new one.
Last but not least, if you do buy a new battery, it'd better be an original one.
Don't trust cheap eBay knockoffs!
Good luck!

do you mean changed it ?

No, I came home and charged it and never had the problem again.
But mine dropped from ~40% to 29% not to 0% like yours did.

How to calibirate battery on miracle v4

Hi can anybody help on calibirating battery on miracle v4 rom

no....nothing can be done
Sent from my GT-S5830 using xda premium

Do bump charging instead of battery calibration. Search it on google.

-Charge your phone to 100%
-Use this battery Calibration app:
https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=de
This app needs root
-Then let your phone discharge until it turns off itself
Notice: in this time you're not allowed to plug the phone to the pc or to the charger again until it turns off
-after it turns off plug the phone to the charger and let it charge without breaks to 100%
-Done

I recall that battery calibration was bogus, there was a post which explained why it was bogus in detail. In other words, don't bother, but charge your battery around 50% if you want a healthy battery.

http://bit.ly/KZdfJJ - Why cant you just google it like he said?
also you can go to recovery and select wipe batterystats.bin
Calibrating your battery does not give you extra battery life, just improves the battery level indicator. Android calibrates battery itself anyway (when battery info change to a few seconds)

batter calibration is of no use i have tested it many times on many roms. our ace has not a good battery. so follow common steps like brightness to 0, application background off etc etc.

thnx will do as u suggested

There is a way to get good battery life in miracle v4 but it took me about 5 days now I get 16 hours off battery with heavy use and about 22 hours for normal use
How I did this
1.let your battery totally die
2.leave your phone off and give full charge
3.still with your charger pluged in boot to cwm recovery
4.now select advanced then wipe battery status
5.now still with with charger pluged in reboot you phone
6.when your phone is fully booted remove charger(you will notice the battery will drop to about 86% in about 10 mins the first time but will get better each time you repeat all these step)
NOTE:I have done this on my wife's s.g.ace with rom miracle v4
And on my Sony Ericsson x8 with many different Rom's
And on my friends Sony Ericsson x10i with many different rom's
YOU MUST USE MAINS CHARGER NOT USB FROM P.C OR LAPTOP AS USB WILL ONLY TRICKLE CHARGE.
If this helped hit the thanks button

And samsung say no update to ics but there are working ics Rom for ace so are Samsung thick or are the devs here from menca ie. People with a IQ of 200+ also was it not google that said android would be lag free from 2.2+ and if that's the case what is the point in developing faster rom's of which all rom's here
Are faster then stock thanks to all the developers that work hard to make the android experience much better

according to the miracle v4 developers the battery indicator doesn't indicate about the battery properly ...will charge now to the max even after 100 % and will let you know what happens

I know battery calibration is useless, but how can ace have better accurate reading. And my problem is that whenever my phone deep sleep for a while and i start to use, the battery decrease rapidly after screen in for a while. Its like the battery is leaking even in deep sleep. Is this a common problem for ace user?

Calibration does not improve or increase battery life. It would just help in getting a more accurate battery level reading. Or so i read somewhere.

Hi, now that i have your attention!
I have cm7.2 democracy on my gio
I barely use it for wifi or gaming now because the battery is S**t.
I had 2.3.6 GB before and battery could take out 2 days on games and music. Now suddenly after switching to cm7.2 i need to charge it twice a day without using any app or game. just some texting like 10, 12.
I use ondemand governor and max freq is 806 min is 245
Also a couple of times i have seen that when my battery is at 30% and charge it then within 5-10 minutes it showed 100% charged. Unplug the charger.
Any suggestions or something on this? I really need an answer guys. Thanks

I can tell you that you can't charge your battery within 10 minutes.
Charge it at least 2 hours, 2.5.

Yeah! I will. Even if it says fully charged. IDK whats the problem with it. It drains so quickly.
Even if i charge it 2 hours even then i have to charge it twice a day.

I have the same problems. Some help?

I am having the same happening with my phone. I am looking into buying a new battery.

My phone goes from 100% to 10% on five min plz help
Sent from my GT-S5660 using xda app-developers app

No one has found a solution 'till now?I'll try to use ODIN and go back to stock version, maybe that will help. Has anyone had those battery problems before using a custom ROM?with stock my battery used to last 2 days with games and music etc, now I can only use it for 5 hours without any games or music or internet. It also charges from 0 to 100% in 30 minutes , maybe less. I'm still hoping someone found a solution for this problem because it is useless to have a phone without any battery.

Try to get a new battery because huge draining problem is not caused by roms it caused by battery damage.my battery runs on stock rom over the 10days without using anything but on cm9/10 roms it drains faster but still runs more than 3days for me.

so no one got it?
Thank God I am not the only one here
But guys, I have been using stock GB for an year. Its been only a week on cm7.2 democracy and nightly.
Both have same battery issues and non of this happened in stock
It's not the battery issue.its something else. I'm sure

Have you tried going back to stock version using ODIN?I think that is the ultimate solution before sending my phone to service(I still have warranty).

Try to "recalibrate" your battery; in cwm theres an option "wipe battery stats". some say its nonsense, some say it really helps; i would give it a try.
No idea if theres an option with stock roms, though.....

I'm calibrating now...Will post the result in a while. (Tomorrow i guess)

I still couldn't solve this..I flashed the stock firmware with ODIN and still no luck, I'm starting to think it is a hardware problem, maybe I will send the phone to service now that I have the stock firmware back. Has anyone found any solution?

Hey, i found this article
For the users who like to try out new ROMs very often or by default Android receives updates to Android very often. These updates re constantly pushed to the users to provide the better experience to the users. For those who flash their mobile handset with custom ROM they are advised to charge their handset to 100 % battery life and then proceed with the upgrade processor. That is advised because if you have 50 % of battery life and proceed with firmware update, the new custom ROM will consider 50 % battery life as the full battery stats and this will provide half the battery life then earlier as specified by your phone manufacturer. In those cases you need to go with the battery calibration to gain 100 % battery backup as specified by your provider. There is complete procedure on how you will calibrate your phone battery is mentioned by us and if you would like to make the process very much easier then you can make use of a specially designed application which calibrates your battery. (Battery Calibration)
Okay so i flashed a new custom rom with 100% battery but no luck on battery issue. Its still draining the same.
then i calibrated my battery with this app with my battery at 100% which of course is 50% as said by this article, the app said "Your battery has been calibrated by 6%". Don't know what that means.
ANY HELP? DEVELOPERS PLEASE GUYS!

Try to calibrate it too.It may fix it.

I have the same issue, I am using CM10.1 RC0 by Olddroid but I think my problem is the charger. For the last month I charged my Gio using the usb connection from PC. Now, if I use the charger the battery drains faster than charging with the usb connection method. I am gonna buy a 1500 mAh battery and hope to solve this problem.

Maybe it's your battery. Do the battery test spin the battery on a flat surface if it spins it your battery. Also if you just installed the rom give a couple of days so it can settle. There's a app called better battery stats that tells you if you have any wake clocks or a certain app that's draining your battery.

If it does spin you need to get a new battery or it can damage your device.
Sent from my SPH-D710 using Xparent ICS Tapatalk 2

If your battery is spinning, it's definitely time to replace. Your battery life will start sucking, and will start shutting off at 65%.
Your phone will lose 1% battery per minute also. You just do not want to have to deal with that while waiting for your new battery.
If you have TEP, take it to a repair center and see if they will give you a new one. If not buy on eBay.
Don't buy batteries from amazon for $10 or the guy on ebay for that much. I just bought 2 from some guy on ebay selling for 13 dollars and some change. I peeled off Samsung sticker on both old swollen battery and the new one and that guy had the real deal. Make sure you look at all negative feedback if you go that route of buying replacement.

Yeah sometimes you get lucky and get a 1900 mah battery instead of 1800 mah. :thumbup:

I used to think it was GB08, because when I first flashed my phone to GB08 from FL24 I started losing %50 of battery overnight compared to just 1-2% overnight I've had with FL24. But it turned out not to be GB08. Go to your google maps -> settings -> location settings and turn OFF Location Reporting, Locating Sharing, Locatin History etc. Now, charge your phone and leave it overnight and see how much battery juice you have left. My phone on GB08 loses 1-2% of battery for 8 hours of sleep with all the gmaps location crap turned off.

Optimus G Pro E980 Battery

hi. i just got my new phone E980. its the AT&T model. the batter is so ambiguous man... like i got the phone just yesterday, started checking out the phone and the battery was like 23%.
after LITERALLY like 10 mins the battery went to like 12%... i was like WOOOOT.....
i discharged the phone completely and then took out the battery and discharged any remaining power from phone as its recommended.
then i charged the phone to full and started using again like paystore apps downloading.
as i checked the battery from setting the idle was using like 3rd most battery in the list after screen and android OS.
what is this man??? isnt it supposed to be a phablet? is it ok for my phone to be this worst at battery. this is first ever non-Samsung phone and i m used to good battery life where idle does not take freaking 3rd most of the battery... WTF... im kinda disappointed
also can someone tell me and pls like me here any good roms and how to root this phone and also tell me which roms provide good battery life?
i will be so thankful for these links...

smiler what happened to me :\
now i need to wait for new battery to arrive
EDIT:
small tip
its might help the sudden restarting if changing the processor speed to 1ghz max

I've solve the same Issue by using an Ipad Charger because the 3140Mah battery need a 2 Ampere charger.
First day my F240L drain full battery in 3 hours, the 100% charge was fake by charging with Galaxy S3 charger (I got Phone Used without Charger), the phone show 100% charge but the value was fake.
Try a charger with 2 Ampere Output.
This metod is working with ipad charger and Galaxy Tab 3 charger.
I hope that my Hint work for you.
Now my battery works very well. yesterday i disconnect phone at 8.30 am and at the 23.30 the charge was 47%, with mid-heavy use and wifi turned on all the day.

Plus 1!

Sorry that's all I got but you will see in the first screen shot during the 3 days the phone was powered on and off charge, the screen used 35% of the battery. I have had 2 previous phones, TMO GS2 and ATT Note1 and never had the battery last longer than around 24-26 hours on any ROM under similar circumstances. That is with notifications enabled and data and Wifi active but Bluetooth off.
2nd screenshot shows phone was sleeping (offline) 95% of the time so if my calculation is correct, on screen time would calculate out at 4394 minutes * (100-95.4) % = 202 minutes or around 3.3 hours during the 3 days I was using it (little more than 1 hour a day). Assuming the screen was on whenever the phone was online.

You just need to press Screen to see screen time
