Hi guys,
After charging to 100% and removing the battery for a few minutes, the battery drops about 10-20%. If I dont remove it, when I get to about 28-30% after 1.5 hours of screen time, it suddenly heats up to 45-47C (around the home button) and drops to 5% in mere minutes.
This problem is about a week old, with no new apps/updates installed, same habits in using the phone and from a battery life of 17h on w/ 3-3.2 hours of screen to 13h on w/ 1.5h of screen time. (4.1.2, stock, non-rooted xxemd2)
No unusual app battery drain (screen, the most, calls/temple run/cracked lite/news republic, and android system with 8%)
Q: Could it be a faulty battery? I've had the s3 for about a year...
Q2: If it's the battery, would you recommend the OEM 3000mah battery? (I need at least 17-18 h on w/ 3h screen time)
Q3: If it's not the battery, could it be a faulty mb? :what:
Thank you in advance for any help you can provide.

it can be a faulty anything. first, factory reset and flash a stock rom. then try a different battery, an oem one. then send it to service

it can b anything as glebun says ,,you can try to see the multimeter reading comparing another s3. put red and black pointer on bettery + n -
so many handsets get damage with wrong chargers..
dnt ever try to charge your precious handset with any charger that fits well in charging socket. voltage and amp ratings are deferant in all
if microSd mounted reomove and see the deferance

skhan
So, already did the test w/ another s3 battery. There is some heating, but not major. And the battery drain seems normal, but still big. (I'll put this on account of heavy device workload on startup) havent had the time to test it out for 24 hours or more... the sd card is not an issue (16gb uhc1, san disk) tried it on another s3.
Again, the only issues i find viable are
1. Something screwed up on the software side, but for it's a hassle to factory reset from the start...
2. Early fault on battery
3. Something hardware got screwed up overnight
Never charged my phone with an retail/different charger from the OEM one...

Anybody had this problem?
I've had my GS2 for nearly 3 months and all has been well. Coming from a Motorola XT720, EVERYTHING is better including the battery life.
Last week I noticed that when connecting the charger, it took a long time for the phone to register that it was connected, ie. it didn't beep, light up and show the charging icon. It was also slow to recognize that the charger had been disconnected. (The charging icon would stay on for some time after.)
I thought a re-boot would help and it threw up the big battery charging icon flashing alternately with the battery over heating icon! Even pulling the battery wouldn't stop the warning message unless it was removed for at least a couple of hours or re-booting via Home, Vol+ and Power.
Whilst all of this was happening, battery life plummeted. I normally get about 1-3% loss of battery per hour in standby but this increased to 5-10% per hour.
The phone has somehow regained its normal response to the charger being connected and disconnected but the poor battery life remains.
Its un-locked, un-rooted and running KF3:KE7:KD1
Any ideas before I do a complete reset?
I would get a new battery to start with, if you UK, 7dayshop.com have an 1800mah for only. £4.49 delivered.

Thanks. I forgot to mention that I've just bought an Andida "2000"mAh battery from Mobilefun. It's only had a couple charging cycles but it's behaving exactly the same as the original battery, which confuses things!
It could be that the problem is effecting it our it's just not working at it's full potential yet.
Sent from my GT-I9100 using XDA App
Even the biggest best know battery manufactures cannot make a 2000mah battery to fit the S2 without needing a replacement back cover, the new Samsung 2000mah needs one.
So the Andida "2000"mAh battery , is more likely to be around 1500-1800mah
Yep, if something sounds too good to be true, it probably is! Will probably return it and wait for the
official Samsung 2000 mAh.
Would still like to know what's going on with the sudden loss of battery life.

Since you have tried a second battery and the phone is acting the same way the fault must be with the phone, the charging socket is not loose or something?
Or maybe the phone charger is faulty, do you have a second to try?
It looks like you should try a reset before you seek refund/replacement.
Good evening all.
When i'm charging my battery with wall charger our pc charger. I cant fully charge to 100. Its saying fully charged but after i unplug its going down to 96 our even 65 percent. And another thing was when is was charging my battery it was at 86 and after that the battery was going downwards instead of upwards ( when in charger ). So i searched on the internet and i found a way to calibrate the battery,turn off foon let it fully charge,take battery out 180 sec and put back in and it should be calibrated. But my problem is i cant get it fully charged because its getting downwards. Even now its stuck at 81 percent and not going furter. annyone got a solotion. Thank you in advanced.
I hope you get an answer, I have had this problem before but changing ROM seemed to fix it...... Please don't ask me to many questions if any, I'm pretty sure I'm more of a noob than you

Thank you,ive tried that already. I am thinking to go back to gb and see how that works. Realy dont got a clue what else to do. And i'm completly new to this,so i'm a noob. hehe
The standard answer you will get from most people on here is "its been covered many times before."
However, I will tell you its the fuel gauge chip. Several charge-discharge cycles should correct the issue. Very common when swapping ROMs.
For example, for the hell of it, I just reset my chip and dropped from 63% to 2%. The chip kind of "learns" over time what full charge and empty is, and drifts about a bit until its fully sure what 100% and 0% are.

No, just fully charge it, then let it discharge completely, charge and repeat, it will sort out its misrepresenting charge after a couple of full charges.

I'm trying to do that,but battery wont charge completly.
Its going downwards after reaching 82 percent our even don't load.After a couple tries its charging again but not to 100 percent.
So when i reach the limit when its going down again pull out wait till its empty and try again? At a sertain point it will be charging again till 100?
Btw sorry for my bade english!

Did you try turning the phone off and then charge it? After that do some charges when the phone is on like stated above.
Yes m8 i did,and trying it again right now.
The weird thing is,when my foon is on. The battery shows like 49. And now i turned foon of,and its seems like the green battery is like 15 our something. I also did wipe battery stats again. And whent back to a stock rom.
I would buy a spare battery, you'll get an official 1 for £10 to £15, that way you have a spare and will also be able to set if your phone or battery has a fault.
With my battery I did few bump charges (replugging it back in after it says 100%) and the battery life is excellent. I don'the let it drop below 15% if I can help it.
Good luck

Problem solved i think.
Got me a new battery,charged on a wall charger (not cable) and it was showing 100 in the phone. Then i charged my origenal battery on a wall charger (not cable) And was showing 100 to in the phone.
Now i found out that my charge conector on the phone,has a bad conection.
So i think thats why it issent loading our stops loading at a sertain point.
Sending back my s2 and hope to get it back soon.
Thanks you all for the help. And have a nice day.
Hello,
So my problem is that the battery is charging & discharging very fast. Charging takes about 1.5 hour from ~0% to 100%, so 1%=1min. It isn't normal, I've had this problems some times. For the last time I'm charging it every time I can, so I don't care if the battery is low. You think this is the reason. I've already did the calibration but didn't help. For now my only idea is to charge it only when the battery is almost empty. Did You had such a problem already?How did You solve it?
PS. Happens on every ROM now
I had that exact problem with my g/f's x10i. Normally it was because of an app that was misbehaving and I'd just uninstall it. Just check ur battery info and see what the culprit is. Ideally you should have like screen as top process, cell standby and phone idle most likely following (in general that is). I still hav some problems from time to time but worst case the battery gives me a full day. You can also wipe battery stats in recovery and try the "manual recalibration" that is letting it un completely down (not even vibrating when you try to power on) and then charge to full, then repeat. Did wonders for me on the x10i and my xperia play. Really hope this helps man, I know how frustrating it can be.
Hit thanks if I helped!!
Just read that it happens on every rom. Battery may be bad but still try the battery wipe from xrec and charge with it off. Calibration never hurts. GL
Jakuburban, have you checked if there is not any software causing memory or CPU huge consumption present? Remember we have solved it in your another thread... but to ensure for it
Also, there might be two another problems:
1.) battery lost its capacity rapidly (might cause after e.g. 2 years of huge usage)
2.) hardware issue - there might be present "parasitive resistance" somewhere on the battery pads or on PCB traces. Which can drain battery everytime.
No, none of the programs is battery unfriendly. It's not gettong hot and the screen usage is on the top as You say.
@HeliumX10 I remember that problem but it's different now. CPU usage is allright. It's just charging and discharging to fast. E.G. my brothers SGS2 is charging about 4 hours to full and he can use it all day long. My battery is charging in less than 2 hours and I can only use it for 1/2 of a day. It's like it is charging only half of the battery ( capacity) and it shows that it is full.

I want to use 2 batteries for travelling where I need a lot of juice for GPS.
One battery will be recharged with the S2. The other battery with an Anker wall charger. That's just a plan right now
I would like to know something concerning the best recharging strategy & battery "calibration" if you are using more than one battery:
If you are using only one battery it's quite simple how to calibrate the system.
But if you are using 2 batteries alternating then you can run into trouble, because the system is "calibrated" to the first battery.
That means if you are using battery1 until 0%. The system knows battery empty. I you are putting the 2nd - already recharged with a external wall charger - into the S2 then I wouldthink that the system is confused, because you didn't recharged it internal.
I want to use 2 batteries for travelling where I need a lot of juice for GPS.
So I would use the first battery until 0% and then change to the 2nd which is already recharged and then draining it until 0% and then again recharging.
The other strategy would be drain the first battery until 0%, then using the 2nd until the evening and then recharging both during the night. But I think this strategy will confuse the system.
Hope you understand the problem and I hope someone knows the best solution!
Thank you for your help!

You don't need to calibrate the battery on the s2. The device should fix the percentage by itself. I would not recommend that you drain the battery fully to 0% as i have heard that it could damage the battery and use multiple cycles for the one you drain it. If you're running SiyahKernel you can try to reset the fuel chip in extweaks. Some say that it's a placebo but I seem to think that it works.
Hope that helps you out

You are over complicating this, just change the battery when it's flat and everything is ok.. I have 4 batteries, two Samsung and 2 off ebay, I always have one in the phone (obviously!), one charged in my pocket and one in the desktop charger.. Never have to worry about battery life
Sent from my GT-I9100 using XDA
The batteries should be charged just right if you use the wall charger, however sometimes when you charge in the phone, it might stop at 96% or somewhere around there, sometimes I off the phone and charge, gets it to 100%
You shouldn't worry about calibrating or whatever, new batteries with li-ion battery should be okay without calibration

sounds inconvenient. better get a big battery replacement along with the new back cover
Sorry for upping this thread, but so (as traslate meaning) can you alternate a 1650 mAh stock battery and a 2000 mAh original Samsung battery without the needing of a wipe/recalibration?
Yes.

i've heard that calibrating is just a myth or something.. i have to batteries and i just change them whenever. (idk if that's bad or not), i don't wanna complicate it or something lol
Calibrating is a myth. Charge to 100% and enjoy.
Yes, no problem if you are using the same batteries like original 1650mah, just change the battery when empty and recharge

Again, sorry to bring this thread back to life.. However I was wondering if anyone has had issues with using two batteries and having the "fuel gauge" chip fault on them. On my previous Galaxy S3 the chip that is dedicated to measuring battery stats, as found on many other phones, developed issues. This lead to the phone registering increases in battery percentage while off charger - basically the battery history graph at any given time had a 60% chance of going down and 40% of going up.
Could the use of two batteries caused the "fuel gauge" chip to malfunction?
Maybe temporarily. But charging it to full and/or resetting the fuel gauge running a kernel that supports same fixes that issue easily.
I love my Mega. It is by far the best phone Ive ever had. But, the problems I have with the power usage and management on the device are a total nightmare.
1) The discharging nightmare:
The battery lasts NOTHING. Basically I get about 5 hours of use.. maximum.. no matter what I do.. and I have slimmed down to the ROM to having that NOTHING active.. I literally am left with active 6 services and I monitor CPU usage that is always near zero with NO apps hogging resources. From what I monitor on the device's battery usage, it's clearly always about 90% from the display! And yes, I dim the screen as much as I can of course, but usually not below 1/2way.. I hate screens too dim. However even just on standby with the screen off I still lose about 5% to 8% of battery an hour. Worse, even with the device Powered OFF, I still lose about 20% of battery a day. The ONLY way I have found out to control battery drain completely, is to take the battery out. That's it. Anyone else with similar symptoms and a fix or, is just that the stock battery totally sucks??? Also, any other off brand batteries are any better?.. (not the fat ones rated at much higher amps but that have an extra bulge.. that I don’t want)..
2) The charging nightmare:
This to me is the worse problem. It is bad enough how quickly this device issues battery, bit not nearly as bad as trying to charge efficiently again. I now have tried 3 different chargers/brands (and cables) to try fix the charging problem that is, it takes HOURS and HOURS to charge the battery. I am talking 5 to 6 hours to get it charged and if the screen is on and Im using the device it actually charges NOTHING at all and still keeps discharging (albeit much slower of course)... the fact is that the charging process is so pathetically slow that is less than real-time which means, with the device connected to power supply, the battery STILL drains if I try use it. This is absurd. However, mysteriously enough I have found ONE way that charges the phone super fast.. using a SONY External Power Pack (model CP-F1L) rated at 2200mAh. This is seems crazy because the power output of an external power pack should be much lower than the stock (and other Samsung) USB chargers.. but, it's what works.. the ONLY thing that works. And I have noticed that when connected to a USB Power charger, the Mega's Red LED light turn on faded.. however, when connected to the SONY External Power Pack, is bright red. Clearly more juice going in.. or something like that. Again, anyone else with similar symptoms and a fix the charging time, or, any good recommendation on a extra strong USB power adapter/charger that will make this thing at least charge faster?
Thanks in advance for the input and advice:silly:
Sounds like something is not letting your phone sleep or the battery is defective. Try putting CPU spy on it and let it set for a while. Then check to see if it is getting into deep sleep or if it is even stuck at a certain frequency.
There is an app on the playstore called Galaxy charging. Try it to see what rate it is charging. Though with the rate your phone discharges, the charger may only being supplying an amount just over the drain rate which is why it takes so long to charge.

Yep, something wrong there. I'm stock and this thing won't quit :good:
I would flash the stock rom back into your phone and see how the battery works then as this not normal as mentioned by other members as I am still on the stock rom but rooted only and I have great battery life.
That is were to start by flashing the stock rom and if no change then battery or maybe a hardware problem.
Did you have good battery life before you starting flashing with the phone or did this occur after the stock rom was removed and custom rom with stuff removed to gain performance?

You could try to remove the battery from the phone for about 5 secs and re-install and see it that helps as sometimes if you take the charger off as soon as it is done charging it might not show 100% at times when booting as I leave mine on for a bit longer and it seems to help..even though charge light is green..I leave it longer on.
If your phone is rooted get a app called battery calibrator from the google store as it is free and install it and just before you shut down the phone to charge wipe the battery stats with this app and then shutdown phone and fully charge and then see how the battery works after the battery stats wipe as that can usually help.

Thanks for the tip. Installed the app you recommend, now I understand better. With the stock Samsung USB charger I get 420 readings. With the other 2 chargers I get 500 and 540. However, with the Sony External Power Pack I get 1900!..no wonder it charges super fast with it! My question now is what's up with all the USB chargers I have? I even tried my old Galaxy Tab 7 charger (strongest rated charger I have) and still only feeds 480. This is all so bizarre. So, where to get a super strong charger for the Mega?

Usually when this happens there is something wrong with the USB cable not necessarily the charger. Is the sony cable a USB type cable or a hard wired one? If it is USB type try using it with the other chargers and see what your results are.

Yes indeed I notice the Sony Power Pack cable is short and thick. The Samsung cable is long and thin. I get much higher charging power using the thick short cable. Maybe I need go shop for a proper longer/thicker cable.

I've certainly found the USB cable makes a big difference to the charging speed. I got a couple of 2m cables off Ebay and they're hopelessly slow, but the stock Samsung cable is fast. I just wish it was a bit longer!
I have the same issue
I have the Sprint Mega. Not refurbished and original factory state but I have horrific charge/discharge issues. Right now, my phone just got to 100% charge which I then unplugged the charge cable. Within 5 mins, I went from 100% to 96% and it is losing battery even quicker.
VeEuzUKY: It's been a while but do you still have this phone? Any updates? I should prob invest in a thicker USB cable like you've describe. It has the most charge rate.
I got my mega 6.3 last week. Since then it has said 100% charged... even when charging or dead. So I got a new battery thinking it was the battery but its obviously not and im not sure what it is that could be the problem. Im not sure if its crucial for my phone, if it can be fixed easily and cheaply, or if I need to return my phone to the place I bought it from.
