Hi everyone, I'm a newbie Android user. Currently I'm using:
DEVICE: Samsung Galaxy S3 GT-i9300
ROM: Android Revolution HD 14.0
KERNEL: Phenomenal 4.0 Medium
I've got battery problem after flashing both ROM and Kernel. I read in the both thread that they (supposed to) have excellent battery life. And there is also a thread about calibrating battery after flashing ROM/Kernel.
I lost 10% battery/hour , medium usage for Twitter(Tweakdeck) and XDA Forum ONLY...
I've done this step to calibrate:
1. Charge until 100% and 0mAh (Current Widget)
2. Wipe battery stats in Recovery Mode
Does the battery completely calibrated? Or I have to use it until 0% / 2% and charge it until 100% again? Am I missing some steps?
Thanks in advance everyone, happy Sunday and may God bless you

Above is nonsense battery re calibrates itself with use .

No need for battery calibration, the android system manages it itself while your charging your phone.

Okay then, thanks Senior! I'll be using BetterBatteryStats after fully charged to 100% :victory:
It is good practice to let the battery hit zero and recharge fully every now and then, but this applies to all Li-Ion cells. I've had batteries last me years with reasonable capacity thanks to periodical full cycles. Otherwise yeah, the actual specifics is automatic.

Total and dangerous rubbish a fully drained battery will not last as long as one that is never drained .

L-ION batteries never reach 0% or 100%. Even when your phone dies and won't come on, the battery isn't at 0%. When you leave your phone on for hours after it is full, it still isn't at 100%...

I recently bought this battery: http://amzn.com/B002MRA8FQ
However, it doesn't seem to last longer at all compared to the stock battery. I thought that maybe I needed to drain it fully and then recharge it the whole way before it would work properly, but I noticed that it was reporting 1% life left for a good hour or so before I gave up trying to drain it. Is it possible that the battery life isn't being detected properly since its not the stock battery or is there something else going on that it lasts exactly as long as the stock battery?
as i read the article, it doesnt apear to be an original LG battery...did u ever thought that batteries are not all about XXXXmAh? More is not always better
Think of cars... an american car(ex Ford Mustang) has an 4000cm3 engine producing 200Hp . Subaru has an 2400cm3 engine producing 300hp
But i could be wrong
Cheers !
You can try wiping battery stats
How do I go about wiping the battery stats? I'm using the stock rom BTW
You need a custom recovery (root your phone first)
You can gohere if you are unfamiliar with these terms
You can do it without custom recovery if you are rooted. Use either Battery Calibration app or Root Toolbox app. Both available in the market.

So I've rooted and calibrated the battery... but it seems that it hasn't changed anything. It is weird that an extended battery twice the size of the original lasts exactly as long (or less) than the original battery
Charge your battery to full, 100%, then wipe battery stats, and allow your battery to DIE. Then your problem should be fixed. i went through the same problem, i bought a special battery with better battery life and my Optimus t, running at 806/480 on smartass governor can run for about 4 days without dying, and thats with constant use

mah DOES matter!
Battery life is dictated by the mah and how you use your phone. It sounds like the battery you received is defective which happens when you buy them from sites like ebay or amazon. Is there a return policy or warranty on the battery? You should definitely get more talk time and standby time with an extended battery.
It is a common misconception that you have to let the battery drain all the way. These are li-ion batteries which prefer a shallow discharge. Meaning, they prefer to be charged when they are at about 25% capacity.
Best of luck to you!

So true. The closer they remain to fully charged the longer they last.
Hello,
I have ordered a new higher MAH battery for SGS II . I may be running stock ROM/Kernel or any of the custom AOSP ROM/Kernel.
During the kernel/ROM updates I have read that we dont usually need to clear the battery stats (since we are using the same existing battery).
However I will now be using the following battery :
http://www.amazon.com/gp/product/B0058SJ5Q4/ref=oh_o00_s01_i02_details
I need to how to properly calibrate the battery status so I can achieve full charge and maximum run time from this battery. Do I need to clear battery stats (from recovery mode) first and then insert the battery for first time usage or otherwise.
Have read a couple of posts on the subject however none provides a clear defined and fixed approach to the issue.
Any detailed guidance would be appreciated to be of benefit for the community in general.
Thanks.
=================================
Guess there are already enough methods and ways and some even debunk the myth that does the phone really needs any type of calibration/calibration apps at all or not.
Will try diving into it directly to see the effects myself if any.
You don't need to do anything other than sticking it in your phone.
When I got the 2000mah battery, I found my battery life to be equal or even slightly less than the stock one. I fully charged the battery, went to cwm and wiped battery stats, used battery completely till it died and then fully charged once again. It did seem to work as my battery life was much better.

He's right. Your battery calibrates itself with a full charging.
i read in a number of articles that you should reset/wipe your battery stats with CWM once your battery is at 100%, then switch off your phone and connect to a charger usb/plug until it will be charged to the actual 100% (usually only 1-2% at most)...

All 100% wrong .
As it only wipes the stats that show and plays no part in calibration of the battery .

thnx for the correction, what do you think about "Battery Monitor Widget" app? Does its function to calibrate actually work?
Got intrigued by the issue...
No, it doesn't. Due to hardware 'limitations', battery apps can only provide a rough guess at best of charge remaining, discharge rate, etc on SGS2.
And genuine (made by Samsung) batteries don't have to be (and cannot be) calibrated. There's a fuel gauge chip in the battery which does this automatically.
Some people having issues with the battery report charging to 100%, removing the battery for a few minutes (so the fuel gauge chip doesn't have power for that time) & putting it back in the phone fixes their issues, but even that sounds like voodoo to me.

Hi,
I was wondernig if any of you guys have used this app on your stock, non-rooted phones?

I feel like I should be getting better battery life.
One more question, if i get a replacement battery, is there a need to do anything to wipe out battery stats, or just pop in the battery and go??
Thanks again
As battery calibration apps can not work and are placebos why bother .
Battery is self calibrating .
Battery stats do not need wiping but you do no harm .They play no part whatsoever in battery drain and do not recalibrate a battery .
Better Battery Stats and Wakelocks first call for battery drain .

For some odd reason my battery icon shows 71%, but if I go to batt status it shows 62%. I flashed a diff batt mod and it changed to the new one, but it's still on 71%. Any ideas how I can make it show the correct status?

let the phone run till it dies and then charge it. that should reset the battery gauge.

Never let the battery drain to zero, it's bad for you battery. These aren't the old Ni-Cad batteries from the 80's but Lithium ion batteries If you want to reset the battery stats just download Battery Calibration from the play store. Charge phone to full and then hit Calibrate and it will reset your stats. Unless something is different with the GS4 or their TW OS any newly installed rom should have this done after installation
Here is info on what you should know about today's batteries.

The statement about li-ion not being akin to ni-cad is correct. The rest is not.
No app is capable of battery calibration. The myth of wiping battery stats to calibrate the battery was clearly and concisely debunked a year and a half ago. Apps such as Battery Calibration ate pure snake oil, as they do not affect battery indication in any way, shape, or form. Additionally, there is absolutely no benefit to wiping battery stats after flashing a rom.
The fact of the matter, as verified by Battery University, is that a complete discharge/charge cycle is the only method of "calibration" available to an end user. By performing a single cycle, the charge and discharge flags are reset. Only a single cycle is needed and this is something that need be performed more than a few times a year, as it wail shorten the battery's serviceable lifespan.

Ummm I said if you want to reset you stats not actually calibrate your battery. That app to clear stats is called Battery Calibrator. Never did i say calibrate battery

There is a far easier way to clear battery stats. Charge to phone to full or near full, and then unplug it. Voila! Regardless, wiping battery stats is not going to do anything for the op.

Well a friend of mine had the same issue with "stuck battery %" and that did the trick soooo just helping out with what worked for another is all. whatever
That actually didn't do the trick, as nothing relevant to reported charge is contained in the file that is wiped. While it may seem logical to ascribe the fix to a proximal act, it is actually a case of post hoc ergo propter hoc.

Neither did this. The battery calibrator app did nothing either. My phone is still showing a percent up top that is not what shows in settings/more/battery. More news, my phone showed this morning, after I unplugged it from all night charge, that it had been running on battery for 8 hours 2 minutes. The whole battery status is fubar somehow.
Just let the phone die, it works , and its easy

That's the only thing I haven't tried. Will do that today. Will report.
Didn't work. Gonna have to dirty flash the ROM.
My S4 (2 months old) dies with the battery at 20%. After reboot (plugged in) it still says 20%. Why does that happen? It should say 0%!
Update
It seems that the battery gives an incorrect fake voltage sometimes. To correct that I turned the camer flash on, using a flashlight utility, and after a few seconds I clicked the quick start button in the battery calibration utility you can access dialing *#0228#.
Now it show 11% that should almost be correct, and it's now charging. I am charging it in slow mode at 500mA just to give it a proper charge.
I'll update you as soon as I have results.
Second Update
Nothing. I think the battery is broken.
It dies at about 20%-30% and when the phone restarts, plugged in, it says it's 20%.
Hey everyone
I am having a problem with my battery drain.A few days back my battery was fine i am using lg LTE 2 phone with a 2150 mAh battery. Overnight the max drain was 3-5 % max but now its like 60-70% overnight and when i wake a up the mobile is hot like its constantly been using. Before i go to bed i clear the ram stop all applications then go to sleep but still drains i even restarted the phone a couple of times still the same
Help please! :crying:

As you are saying that your mobile seems "hot"
First you need to confirm that its charger/device issue or only with battery.
First do battery calibration with this method: (In this method you need custom recovery for your device
This may help you

Dont forget to thank him there on his thread.
IMPORTANT: You can skip this step>> "Wait 20 min after you are sure it is 100% (phone should stay plugged in)" - As i dont know much about LG devices and their batteries
Now some advice from me-
If you can cover it >>> Never charge battery again and again before 15 or 20%
Always charge your battery to 100% at once and use your device till 15% or less than 15% and then again charge it full and so on...
This will make your battery backup good as well for battery life

According to the Battery Doctor app, you shouldn't leave your phone on charge for more than 9-10 hours(MAX), otherwise it WILL harm your battery.
You should try hibernating some of those apps with Greenify.

Use better battery stat (check play store) or similar app to track draining application.
In this way you can find a culprit
