Hi guys.
Today, while I was playing with NOVA 3 and charging my phone, I notice that the battery of the S2 had been uncharged a little. This is a little weird because my phone was in charge. I know that games (NOVA 3 specially) are big battery eaters but I've never had a phone that discharges it battery if connected, neither sleeping or awake. Battery Widget says, with phone unplugged, that NOVA eats over 800 mA while playing. Is this nor.al? Anyone can play that game while charging and check if happen the same as me?
Any help will be appreciated. Thanks in advance.

So I need to reset fuel gauge? Or you may want to sat that altough phone marks that battery level, phone is actually charging. ?
Thanks !
PD: I use Official Extended Battery.
If it suddenly drops from 60 % to 5 %, worry.
If it goes up on it's own, don't.
It's up to you, fuel gauge can be fixed. Read about it, It's here in xda somewhere.
Mine goes up 2, 3, 5 % when I unplug it sometimes, so I think of it as a wireless charger

Not just that. But yes, it doesn't drop from 60 to 5, but goes up. However, that's not the problem. The problem is that when I'm playing phone demands more energy than provided by the charger, so battery goes down instead going up. I've never had a phone that do this way, playing games with the carger or not. This has made me think that could be a problem with the charge port or something like that so in order to discard this hipothesis I attach you my last charge history of tonight. I hope it's normal.
It seems like charge is irregular. At the first percents, battery grows slowly but in the middle of the capacity (~50%), charge rate is around 800 (while in theory our charger gives a max of 650 mA). That could be the answer. But I'd want to know if my charging is normal.
Thanks.
Nasty.
When batt gets to 100 % remove it and let it sit for a 3 min, then put it back.
There's a lot of battery threads here in Q&A.
Try searching key words like "charging" "volting","fuel gauge", "battery drop", "power drop" and so on.
Betterbatterystats is also a good app to see what's going on with your battery. Highly recommended.
What ROM are you on again? If stock, you can always flash a custom kernel, improves the battery life significantly.

I'm on Stock 4.0.4 with Apollo kernel. Battery is not bad for me I think but the problems it has, like:
-With stock 1650 mAh battery: sometimes I got freezes while i'm playing and when I reboot the phone, battery has dropped from 60 % to 12 %. But if I leave my phone on idle, battery recharges itself. WEIRD.
-With both 1650 and 2000 mAh, if I play intensive games while phone is charging, battery doesn't load. Istead, battery drops 1 % per 10 minutes approximately. WEIRD.
Anyway, thanks for your answer. I will try better battery stats and read anything else in forum.

Ok so Here's the deal
When I flash a rom I charge the phone till it hits 100%. I then reset the battery stats and go on about my day. With in a few minutes of being off the charger my battery has now dropped down to about 96 %. I do realize that batteries do not stay at 100% but this is crazy. I've only deep cycled my battery once for fear that it may damage my battery.
I Am using Teamwhiskeys ultra awesome bionix-v rom with ttabals oc kernal. I know I am to expect a slightly more rapid drain but this is crazy. I have even tried to lower the vcore and I slowed down the cpu to 800mhz. It still drains just as fast.
The odd thing to me is If i turn my phone off and let it fully charge to 100 percent reset stats then turn on phone It will show full for a minute then drop down to to 96 or 95 percent.
I personally think my battery is damaged but spare parts shows that it is ok.
So i am rather confused by this .
I know I should probably use the stock kernal but it seems like its just as bad with that.
I have looked at the threads about battery life and I am not expecting it to be amazing just hoping it will be ok!
Tell me what ya think !
mt battery play tricks on me too when my phone doesent see that im lookin at it it shows 90 when i look at it and phone notice it bounces to 85 like it hates me , lol but dont take my words for it P
Spare parts would show that too. I remember when I had my G1 spare parts would tell me it was fine. But a 3 hour full battery doesn't seem fine does it? Id suggest getting it replaced.

Ill probably nurse it... but I am having major ocd type problems about it.
I cannot stress this part enough, so I'm putting at the top, do not do the following often, as it can have a negative effect on Li batteries if done too much.
You want to try what is known as a bump charge. With your phone off, charge to 100 percent. You will see the green battery icon with "100" on it once it reaches full. Unplug from the charger for a minute, then plug it back in, phone still off, and let it reach 100 again. If you want you can do this a third time, do keep in mind, bump charging too much or with any type of frequency can have negative effects on your battery, but doing it once in a great great while helps with with what you are experiencing.
thanks Br1cK'd and those who replied.
I have tried the bump charging method. I am affraid that my efforts to repair my battery are causing it more harm than good.
ok i just restored bionix v and had it charge to 100 percent
spare parts says
battery level 100
battery scale 100
battery health good
battery voltage says 4243mv

There is one thing you are messing up. If you flash your phone on a 100% charge then you DO NOT need to wipe battery stats. You only have to wipe battery stats if you flash when your battery is not at 100%!

It's not out of the ordinary for a battery indicator to show a few percent drop rather quickly on a LiIon battery. Secondly you should take a battery indicator with a rather large grain of salt. Expecting precision in single digit percentages from the indicator is unrealistic and nearly impossible to rely on given the nature of discharge of a battery. Batteries do not charge or discharge in a linear manner, and people do not use battery powered devices in a linear way either.
It is a visual guide, not a precise and accurate indicator. Many custom roms have a percent accurate indicator, but don't mistake this with being dead-on accurate. It is merely an attempt to make it a BETTER visual GUIDE.
To evaluate battery life properly is moderately time consuming, though rather obvious. Use your device as you would normally. Pay attention to how long it stays charged. If it's not staying alive for a reasonable amount of time (12-24 hours depending on what you are doing of course), then it's time to dig deeper. Apps that wake up and generate unnecessary Partial Wake usage, a lot of background application syncing or apps with short sync intervals, being in an area with poor data/voice signal....these are the usual culprits.
Apart from situations where people are playing around with experimental kernels (i9000 derived kernels tend to vampirically drain battery a few percent an hour regardless), the things that drain your battery are....things that "use" your phone. The more you do (and the more your phone is doing with your permission while it's in your pocket) the less battery you will have.
In the end it comes down to asking yourself some questions. Do you need to automatically update facebook, myspace, twitter feeds constantly when you can manually update them and be inconvenienced by a 10-20 second wait? Do you really need to update 35 rss feeds in Google Reader?
Most people's power related issues come down to three things.
1). Apps that wake up without your knowledge and waste battery for no good reason (I'm looking at you Media Hub!!)
2).All those other apps and widgets that are updating inside your pocket when your not reading, watching, or caring about them.
3). Being in an area with poor data/voice signal, forcing your phone to "hunt" excessively for a better connection.
Apps that wake up and do god knows what without your knowledge can either be removed, disabled, or frozen. Examining partial wake usage can give you insight into what may be going on in that scenario. Apps can be "Frozen" with Titanium Backup Pro (paid) or App Freezer (free).
The other part that is within your control are all the apps/widgets you actively use, and your decisions about how often (or even if) they update themselves.
I'm having this problem with my i777.
Sometimes when I reboot the phone the battery charge drops enormously, like 30% or so. For example, I will be doing things with the phone, the charge will be at something like 60% then reboot and right after reboot it says charge is 30% which doesn't make much sense.
this happens with the stock battery but the effects seems to be more pronouced with some batteries I bought on ebay.
Anyone has any idea what's going on?

Normal behavior of our fuel gauge hardware - high load (boot process) immediately after a reset confuses it and makes it report low. Effect is much more pronounced at lower states of charge.

That's exactly right. Tends to happen more on lower states of charge.
Does this mean that the charge indicator will go up after the reboot? Or maybe it will take longer to drop and the effective battery life will be the same.
Yes when this happens to me my bettery either dies extremely slow or my percent just goes up..

I see this too. I will be at ~40%, reboot and see 10%. Come back after a while to 12%, and it stays on 12% with like an hours worth of heavy use before going lower. If I look at the battery usage, it trends down, then drops, but stays level, then about when the trend would have been it starts dropping again.
I thought I just needed to calibrate the battery, as I just flashed a new ROM. But, it keeps doing this after a week, and several charge cycles.
Guess I'm relieved to see this weird behavior is not indicative of a problem.

Correct - because the gauge thinks the battery is lower than it actually is when this happens.
Attached a screenshot of the battery use with the big drop in effect.
I particularly think this is a bug and Samsung should fix this behavior.
It can't be changed without hardware alterations.
As with anything in engineering, there are tradeoffs. The positive aspect of this fuel gauge design is that it does not require ANY calibration. No wiping battery stats, no "always flash firmware at 100%" - none of that.
The negative is that in a few corner cases, it gets thrown off temporarily. This is basically the only known one.
Ive noticed this as well with both Stock and ICScreweD. I just try to reboot as least as possible.

If you reboot at higher states of charge, OR reboot when on external power, you should not see this issue.
I just had this same problem lol. I was at 42% and when I rebooted my phone it dropped to 23%....This was a few hours after the OTA update to 2.3.6.
I had the same problem also.
-Battery would not charge to 100% ( it would charge between 97% -98%)
-Battery would drop 20% or 30% percent (when reboot).
I tried to recharge many times and cycles the battey but nothing would work.
I tried changing kernal, modem and roms . Nothing would work.
I actually thought i messed my phone up.
So i tried something that work for me.
1) i would let the battery drain till it was completely dead!
2) I would take battery out for 5 minutes.
3) put battery in and charge with phone OFF till it reaches 100%.
4) unplug charger from phone and take battery out and wait 5 minutes.
5) put battery back in and plug charger up and wait till phone marks 100% again ( This time the wait was longer to get to 100%).
6) i repeated step 5 untill finally the phone would mark 100% faster
7) unplug phone and then wait to see the battery status ( if your phone mark 99%) plug charger to phone and let it charge till it reaches 100% again. once it reach 100% reboot and repeat step 7 untill you reboot and it would show 100%.
not sure if this might work for anyone else but it did work for me. battery would charge to 100% and i don't have my phone drop 20-30 percent after reboot.
If it drops 20-30% on a reboot when the battery is near full, you may have a defective battery.
I've only seen major drops on reboot when the battery is low to begin with, never when at higher states of charge.
Doing a full discharge on Li-ion batteries puts a huge stress on it and greatly decreases the life of the battery. To get the longest life out of a battery, you want to generally stay in the medium range of charge (Don't over charge it, and don't discharge it too much). Cars like the Chevy Volt employ these techniques to encourage a longer battery life, however with phones, you get users that think discharging the battery all the way solves problems. If you want to see the true battery life that the fuel gauge averages from, press *#0228# in your dialer and check the battery voltage. Full is around 4.1v and discharged I believe is around 3.5v or so. (maybe 3.3? not sure)
3) put battery in and charge with phone OFF till it reaches 100%. <-- is probably what fixed it, and why I switch batteries instead of charging on my phone because the charger is able to control the current and voltage better than with a slight load on it (with phone on)
I'm sure that that user cut off at least 5% of his overall battery life with overcharging it like that though...
Same issues here pending the ROM I'm using.
4.2 volts is the upper limit for li-ion - and actually, it hits that at around 95% charge.
The method for charging Li-Ion:
Charge with a current limit initially - on our devices this is 650 mA.
Once you hit 4.2 volts, do NOT go above this - maintain voltage at 4.2 volts or lower regardless of current
Once current drops to around C/10 (on our devices, this is about 160 mA), shut off charging completely.
The phone's charge controller does this all automatically for you.
There's usually a timer/averaging filters in the final stages of charge termination - which is why "bump charging" can push a little extra into the battery - but this will lead to degradation in battery total capacity.
As somewhat of an extra trivia on Li-ion batteries, Motorola has apparently managed to get batteries that have nominal voltage at 3.8v and max charged voltage is around 4.3v as opposed to 4.2v.

Obviously its not 100%, even when I charge it overnight, when I unplug it itll be stuck at 100% for like 2 hours then all the sudden drop to like 85%. im lucky if my battery lasts 12 hours now , same thing has happened on different roms.

try "battery calibration" app. it helps me a lot, and keep my phone running longer. i can last almost a day with medium use.
i have also tested with on screen non-stop (wifi + online game that require wifi, brightness roughly around 30%, medium volume, with whatsapp and talkbox in between), in conclusion, i can run for 4hours plus straight with sufficient battery left. i never push it through, i think i can go for 5 hours if i want to.
battery calibration app can be found in play google store
Worst battery life evah!
Im having issue with my battery as well, I plug it in a electric outlet for about an hour last night and when i saw the charge, it was only like 49%!!!!
And today, before my meeting it was like 22%, after an hour of meeting, BOOM! EMPTY BATT! What I only did was surf and checked my calendar!
It charge slow! And its draining fast!
something happened to my battery before last month, when i charge my fone it says 88% then suddenly after few mins 1 or 2 it become fully charge,but when i unplug my charger it comes back to 88% again, i tried some apps like battery calibration and also i'm wiping the battery stats in cwm everytime i flashed a new rom and it helps my battery charge in normal and accurate level...i'm using also cpu spy to checked if my fone is going to a deep sleep. now my battery lasts for 1day 11hrs with light usage. but for heavy usage i've got 40% after 4hrs of continious hd gaming.
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.

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.

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: 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.
From my XPERIA X10S v8.2 on kCernel @ 1.19ghz
Hi everyone i have been using wifi 5.0 about 3 months now it satisfied me enough and i am sure will continue. But the only issue which makes me unhappy is when i am gaming or using gps battery finishes rapidly. I would like to learn when to charge the device is 25% ok and when i am using it on charge even when its full is it bad for the battery life?
Yes you should unplug it when it gets full.

don't leave it on the charger longer then 20-30 minutes after it reaches 100%, any longer can be damaging to the battery if done repeatedly.
Wish these chargers were more like the motorola ecomoto chargers that cut off charging automaticaly once the battery hits capacity.

Thank you for your answer but every time i am charging it over nights i am always turning it off and go to sleep what i want to say i cant wait to be 100% then sleep is there any app to stop charging when its fully done. And isnt it ok while gaming o keep the charger cuz u know after playing 1 hour of fifa12 battery nearly going dead? thanks again.

So you mean this devices are not made for using on charge like laptops?

stopping charging has to be done within the charger itself, so no there is no app that can stop it, plus apps couldn't do anything when the device is powered down anyway.
An hour of a game kills your battery? I can play atleast an hour probably closer to 2 of angry birds and thats from less then 30% and i'm on the 4.0 player which has a much smaller battery, sounds like you've got some battery drain issues to work thru.

yeah u are right about apps no way any app to work when the device off.
I mean maybe 1h and 20 min. with 50% brightness on and i guess fifa use more data than angry birds when ur playing.
anyway its important to know that i shouldn't keep charger on when its 100% because usually when i am home i was using it like that thanks again.
do u think the app called 'sense analog' may make the battery life shorter.
Something is definately wrong, because I can play MC3, which is even more intensive the FIFA on my Gplayer 4.0 for more than 1.5 hours and still have some life left, and the Gplayer 4.0 is only rated for 4/5 hrs and yours is rated for over eight!
After a full recharge, while still plugged in download battery calibration from the market, and follow it's instructions, after you do, while STILL plugged in, reboot. After a full reboot, unplug it, and DO NOT REBOOT until your gplayer completely dies (forces shutdown). Once that occurs, plug it in, let it charge to 100% (while on), leave at 100% for about 15 minutes, unplug, and use as normal. That should fix your issue, unless your battery is dying, which should not occur, even if you are abusing it badly, for awhile longer.

haven't seen the 5.0 screen in person but if the brightness levels are anything like the 4.0 why do you have it so high? My brightness is at like 15-20% with autobrightness OFF.
First, like many others already said, it sounds like something is wrong with your battery. I'm on a 4.0 and playing two hours of a really intense 3D game with auto-brightness indoors will bring the battery from 100% to 50% (maybe it even uses less battery).
Second, as to how to conserve battery life, Rule #1 (as others have said): definetely do not keep it plugged it at 100% for too long. Then, something I tried on my iPod and have been using ever since: keep the battery between 50% and 100%, and once a month, completely empty the battery (until it shuts down) and after that charge it to 100% (this is called a charge cycle). As to my iPod's battery, before I was using this, the battery life got shorter and shorter, but after, it didn't shorten noticeably anymore. On the computer I'm writing this on, for a couple of months, I barely followed this plan, and I lost about 5% of my battery capacity (I have a battery widget that tells me what the total capacity is) within one or two months, but then I started following it a little more closely, and actually got some of it back. Over six months later now, I have lost about 10% of my battery capacity (from the original capacity), except that I should do a charge cycle in the next couple of days, and the last time I did a charge cycle, I got about 5% of the original capacity back, not to mention I have broken rule #1 probably too often and for way too long, often for several hours
My 5.0 can play games for hours before it dies but it has strange batery levels..From 100% to 75% it goes very fast.around 40 minutes when you play game..and then on 75% it stays there for 2hours when you play game and with regular use it can stay all day on 75-70% ..after that it fastly drops to 25% and just when you thing you need to recharge it can stay on 25% forever..you can play 2 more hours of game on 25% or with lighy use it will stay all day on 25%.

This is not correct. NO modern device has ANY smarts in the external charger - nearly all current phones (and every smartphone on the market for the past 3-4 years) has a constant voltage 5.0 volt USB input. Modern "chargers" are not chargers at all - they are dumb 5 volt power supplies, nothing more.
Charging "smarts" are handled by electronics in the device itself and have been for ages. (For all practical purposes, the Player 5.0 is a Galaxy S smartphone minus the cell radio...)
The kernel and charger hardware automatically handle charge termination and restart themselves. This is, for example, why Daily Driver can charge at higher current levels than stock at low battery (but drop the current as the battery reaches nearly full in order to stress the battery less).
Oh, as far as battery percentage display - the method used for estimating state of charge on the Players is abysmally primitive and highly inaccurate.
Battery Charging YP-G70
I always charge my completely standard YP-G70 overnight. As I understand it, the charger only provides voltage and in this case it's 5vdc. The device's battery management software draws the required current to charge the battery. If you install 3c's "Battery Monitor Widget Pro" you can see a charging graph showing the current levels drawn over the full period of charging. The charging current is stepped to control battery temperature and is reduced as the battery approaches full charge. By the time the battery reaches full charge the current draw is down to a trickle charge and will not overcook the battery. I usually leave the device switched on, which further protects it by maintaining a small load. One of the problems I have found with this device is that this charging regime, along with the fairly large capacity of the battery, mean that the battery can take up to six hours to fully charge, which confirms, in my view, that overnight charging is OK.

First of all thank you for this valuable information, thus I can keep my device on plug while i am driving and using gps otherwise on long distance its annoying to keep checking the battery while driving with gps app on.
Other think is i guess its normal but just to ask, The device becomes really hot on charging while i am gaming. What do u think?
Is there an app that takes time of your battery like today I turned on at lets say 7:00am and the battery dies at 9:00 and you forget the times but the app says how long it lasted. Is there some app like that?

3c's "Battery Monitor Widget Pro" gives all the battery information you could ever need. A data log and graphs allow performance to be analysed over any period of time. You can set markers to indicate charger plugging and unplugging times. Hope this helps.

Off course it will be hot..you play game which hots cpy and gpy and at same time you recharge batery which hots battery..but if battery reach 50 degrese celsius player automaticly stop recharging no matter whow much battery is full.

Gaming = CPU and GPU cranking at full tilt with the display on - of course it's going to get warm.
