Ok so this is what i noticed has been happening with my phone...
I wake up in the morning and i unplug my phone from charger at 100% battery life...
after about 1-2 hours of no use (outside of occasional check of time) and no programs running i notice that 25% of life has diminished...
i have turned 3g off and done most of the kaiser tweak settings that help with battery life. for the rest of teh day i can use the phone and battery life runs normally but it seems the first 25 to 30% drops real fast without use
is everyone experiencing this? is it normal?

The problem lies in your first sentence. "I wake up in the morning and unplug my battery." You are charging your battery too much thus killing it's battery life. I only charge my phone in the day while I'm at work. That way I can unhook it when it's fully charge. I would go on ebay and type in OEM battery Kaiser. You can pick one up for 15-30 dollars new.
From what I understand. Leaving your battery in the charger when it is fully charged should not damage the battery as long as its not there for an excessive amount of time but i might be wrong. Either way i have no way of charging the phone during the day as im on the go most of the time so this would mean even if i get a new battery it wont matter because it wile eventually do the same as i have only used this phone for about 3 or 4 months now. any other possibilities or solutions?
or should i just take it as it is and just buy a new battery maybe a bigger seido?
I thought Lithium ion batteries have overcharge protection. I charge mine overnight which I am sure a lot of others do also with no negative effects.

I do... Maybe I shouldn't?
I would hope it has Overcharge Protection!!!
With NiCad Batteries if you overcharged them you would kill the life of the batteries.
And while all batteries do this LiIon are least tolerant. If you overcharge a LiIon battery, that is without Overcharge protection, the LiIon Battery with BURST INTO FLAMES! Thus the problem with the Sony Batteries that caused all those Laptop battery recalls.

Thats total BS with lithium batteries.
To the OP: Try running down your battery completely once, until the phone switches off by itself, then recharge fully. If you never do it and always recharge before the battery is empty the battery's power meter can lose its calibration over time and display weird things.
If it doesn't help, and you can notice a drop in overall life time you might need a new battery.
I have the exact same "problem" with my Tytn II.
Is slows down evenly though. (So the first 5 % of battery vanishes in minutes basically while the last 5 % can last for an hour, when it's half full % will last somehwere in between these two extremes).
Personally I've just interpreted this as poor measuring done by the hardware and/or software. (Ie I don't think the battery performs better the less full it gets as the meter in Windows would have me think)

may seem a daft point but after draining the battery, dont charge with the phone turned back on. gives a fuller charge cos its not being used and makes it quicker to charge, lol

Hmm...I don't see how turning my phone off to charge would increase the charging rate dramatically. My phone in standby mode uses 1% every 2 hours.
depends highly on roms and especially on radios.
with a crappy rom, battery could drop as fast as 10% per hour.
with a decent rom, battery drops in standby mode at a rate about 2% per hour.

If the phone is on but on standby that barely changes a thing. If it's on, with display illuminated then yes it might take you an extra 20 minutes to charge.. no big deal either.
*UPDATE*
ok so i drained my battery last night completely(turned on navizon, tt7, and skyfire) which took me about at most 2 hours.
Put it in for a charge
woke up at 9 and checked to see and it was 100%
I have push mail set to update every hour and i also run pocket sportscenter autoupdates which updates every 10 to 15 minutes
I used the phone for 5 minutes of calls
5 minutes of web surfing
a few text messages
and the occasional time check
at 6:30 pm battery life was at an amazing 90%
i was thrilled.
i continued to surf the web heavily from 730 to 8
a few more text messages
at 9 battery was at 67%
so i gotta believe that draining the battery helped recalibrate it...
i guess every 2 or 3 months i got to drain it out and give a full charge
thanks for the help guys
really appreciate it
I have had my Galaxy S for a bit over a week now and am pretty disappointed with the battery performance. Most days I take my battery off the charger at 7am and it reaches 15% low battery warning by 1-2pm. I do spend a fair amount of time reading XDA and listening to music. I'm currently running Stock JM1 firmware with no lagfixes.
Here's a list of my apps that I have installed:
http://www.appbrain.com/user/Lokhor/apps-on-the-samsung-galaxy-s
I am running JuiceDefender which I thought would make a big difference and does not. I have also set Tasker to change the Brightness level to 20 (below the safety threshold) when the battery reaches 50% or below, otherwise the brightness is at the minimum (30%).
I have heard that you need to condition the battery so I have been trying to do this but it doesn't seem to have had much effect. Today I used my phone only casually and it's currently at 22% after 12.5 hours. The battery use details show the following:
Display at 56% being on for 2h22m and 13s.
Cell Standby 18% Time on 9h21m, time without signal 13%
Phone Idle 7% Time on 7h33m
Android System 5% CPU usage 23m39s CPU foreground 24s
Android OS 3% CPU Usage 13m 27s
Is this normal? Is there anything I'm doing wrong?
Please help
I don't know what others are telling you about conditioning a LiIon battery but you don't have to. LiIon batteries don't suffer from what NiCad do. Some do suggest wearing the battery down to nil and then charging it up again. However, this is pretty bad for the battery and should not be done more than once every 30 cycles. With every LiIon battery I've ever owned I've either trickle charged it or charged it when it wasn't too low and they've all lasted over 3 years. I've never conditioned one.
Anyway, my advice to you is to see how long your battery lasts in standby. Mine could probably last 3 days or more if I don't bother it too much (with sync, wifi and all that good stuff). I find the worst contender for battery drain is the display. The only problem I see with your stats there is that I've played Asphalt5 for around an hour and a half which is quite heavy on juice and it only drains roughly 10%-15%. Then again you're browsing the web so maybe probably worse.
Oh, and when charging your phone, don't use the USB hooked up to a computer as it doesn't stop charging when it's full. Use the wall charger to charge.
no need to worry more

I found that charging it whenever it was convenient instead of when it was low would result in a charge that lasted ~24 hours.
I've noticed significant increase in battery life since I started waiting for the 15% charge warning, plugging it in till it was full and then unplugging it. I get 2-3 days of use this way.
I also set my email to only sync between 6 AM and 11 PM. I believe this helps a lot as well.
since we are about this topic, check this out
How to spot fake battery vs. OEM battery: http://forum.xda-developers.com/showthread.php?p=7953322
so if I'm listening to music during the day at work should I have my phone plugged into the wall charger or just let the battery run down?
Last night I took the charger off at midnight when it was full and when I woke up it had only dropped 5%. After reading my emails quickly it was at 93%.
it works fine either way

I find leaving the brightness on automatic uses up loads of battery. Setting it to lowest seems to make the phone last 24hrs+
I also found that having beautiful widgets clock/weather installed used up a lot of battery for some reason.
I don't use weather because it has to sync every so often to update it which to me is a waste...I'll just look outside. I also leave brightness on the lowest setting wherever I am as the screen is already very bright (why waste battery?).
My experiences with my SGS have taught me to be conservative with its battery. Anytime you turn the screen on, you eat power like crazy. The best bet is to just top her off whenever the need arises. Personally, I have found that I'm fine just topping her off in the car when I'm driving, so that I start my work day at high 90's, and especially once I've got my morning browsing out of the way, I don't eat a big chunk of battery at any other time.
But yes, if you find you are running low, you can happily just take a half hour to charge from a USB port to give you an extra boost. Alternatively, spare batteries and so forth do the same thing, although it can be annoying if you don't have a charger that will do the phone and a spare battery at once.
im experimenting with apndroid now to turn of 3g then i dont specifacly need it. It comes with an on/off widget. Looks promising so far. 40% at 2300 hour and then i have used wifi a bit, played angry birds and talked for about 2 hours in total.
So most people should have heard about currentwidget by now, most people talk about it and use it to see what battery drain occurs during standby mode or airplane mode.
Now I'm sure most know this but incase you didn't, currentwidget helps to ensure your battery is fully charged as well. This is good for people that complain about their battery dropping quickly after a full charge.
You can use currentwidget to monitor your charge, when the battery says its 100% and led is green, currentwidget still shows power going to the battery in form of "ma". I noticed my battery said it was charged and eventho at 100%, currentwidget still showed "ma" is being delivered to the battery . After two hours only it showed 0ma, now I'm sure that means that eventho my phone said its charged, it wasn't fully charged until 0ma were displayed in currentwidget. Since I noticed that, I've been charging my battery "fully" and did notice my battery stayed much longer in the 90-100% aisle when being unplugged.
So if you feel ur battery drops too quickly from a full charge, use this widget to help monitor your charge.
yep, tnx for the tip, im useing clarus battery and its do the same - and i like the widigt so...
the current widget always shows some value of mA . how do we know when the battery is really full ?
Well with me after 1hour at 100%, it shows 0ma. That's when I know the battery is completely full and reached its maximum capacity.
I don't think waiting for the battery to get to the 0mA level is good for the battery performance. Usually the green LED comes on when the widget shows 50mA.
A high-charge concentration for a long time in a Li-Ion battery is bad for the battery. Thats why mobile phones have a little buffer to stop the entire capacity to be full, and try to lose the first part of the full charge as fast as possible.
Since i use some RC Helicopter with li-po/li-ion that both have the same way to produce energy, I have learned how to use this kind of battery and how to ensure a good battery life/durability.
There is no reason to worry about the battery if you follow those few recommendation (given by a battery producer):
-Your battery has to be charged with a current of 1C max (1C mean 1230mA for a 1230mAh capacity).
-Your battery voltage must not be over 4250mV. If you go over, you may damage the battery and risk random explosion/fire. In normal use, it's better to not go over 4200mV.
If you charge the battery with your phone, you will never be able to go over 4200mV because the charge stop automatically before.
-Your battery must not be under 3300mV. Same risk as above. In normal use, it is better to not go under 3450-3500mV to ensure a good battery durability (numbers of cycle charge/decharge). I think the phone show 0% at near of 3450mV, but never check this cause i never wait my phone to be as close to the death.
-Your battery has to be drain at a current of 10C max, i.e for desire HD , 12.30A (1230mAh x 10).
impossible to reach that current with your smartphone so no worries about burning your cpu with heavy bench.
Whatever you do respecting this will not be harmful for your battery.
Hello everyone!
This is my second post here...but I really felt like I had to take attitude this time and actually do something.
So my samsung galaxy s3 is acting so weird that I can't use it without something bad happening for one day.
So...first of all...my battery doesn't last more than four hours straight if, for example, I am listening to music.
It literally goes down about 1% every few minutes.
Also..there is something really weird happening with my battery even after it completely shuts down. Lets's say I am on 1% and the phone shuts off. After the screen goes black and I plug it in...the charging screen appears and the battery seems to be half charged. I open the phone again and it is already at 45%. All this operation takes a matter of seconds...but still it goes from 1% to 45%. After the phone is up...this percentage starts to go down even faster than before...in the end my phone shuts down again...and this time it starts to charge from 0%.
Today it shut off...and when I got home and plugged in the charger it didn't do anything...i just left it like that for about 10 minutes then tried to power it on without the charger being plugged in...and it worked. After that it started to charge. I have no ideea what is happening.
Also...my charging time is really big. I do not know why but when I use another charger from a samsung galaxy mini 2 it seems to charge way faster.
That's pretty much all so far. If you need more details, please let me know.
I hope you can help me sort this out!
Best regards!

1.Might be the battery is dead or broken, or its not calibrated. How old is the phone and battery?
2. It seems to take ages to charge my s3 lte too, give us a number in hours how much time you need?
3. The problem where phone wont turn on or show charging when battery is as low as 1%, i had this too, i think its normal, its protecting the battery
4. Do you have overcloacked anything? It happend to me when i had ovecloaced and did benchamark test, the phone froze and battery eas 5% when i restarted the phone, but before it was 45.
Not realy helpful but i am trying XD. Also might wanna buy new battery, its not that expesive
if you are running stock rom with no rooting no anything....100% it's the battery.
if not install stock and see how it goes...if it's acting normal then the mods are the problem...if it's the same it's the battery.
Do a factory data reset on stock recovery. See how that works out first
Starting from factory reset is bad idea - it should be the last step IMHO.
First what in such case we need to check is battery health.
Percentage we see on our phone is weak indicator, because it is calculated
Better to see the voltage in different situations. How to check this (terminal app or adb in console):
cat /sys/class/power_supply/battery/voltage_now
The lowest voltage that device can handle without heavy usage is less than 3500mV (I saw even 3240mV, but with low brightness, no data connection and after trying to make a call phone turned off).
The maximum voltage is obout 4300mV.
When You see 1% of battery and voltage is realy close to 3500mV or battery is charged and voltage after removing charge is dropping realy fast to then your battery very likely need to be replaced.
I bought Samsung Extended Battery (3000mAh) and this tripled the time usage than my 2 years old normal battery 2100mAh. You can see that difference in their capacity is much smaller - about 43% biger, but give me 300% much time on battery so old one was realy worn out.
BUT if your battery wasnt used for longer than half year, you can do as follows:
1. Discharge battery
2. When phone turns off - turn it on again, but into download mode (Home-VolumeDown-Power)
3. Leave phone for as long as it turns off again and repeat step 2 till time that Download Mode wont even boot.
4. Take off battery and place it back, and again try point 2 (start Download Mode) - do it until phone will show Download Mode for only 2-3 secconds
5. Again and last time replace battery and charge phone, but turned off
6. When phone will be charged, turn it on and leave it on charger for about one hour
After those steps use your phone lightly and try to repeat whole process one more time but only when the battery will normaly discharge and phone will turn off.
I tried those steps and battery for sure can work longer FOR ONE RUN, but unfortunately it can lead to loss of capacity much faster, but it will be noticable after one year - IMHO its always good time to buy new battery.

Nothing good will come from that procedure. Those steps were useful in the epoch of nickel-cadmium batteries, where the battery had no internal circuits to monitor itself and had a tendecy to uncalibrate. Those stops would force the device and the battery to re-adapt to one another.
But now we're using Li-Ion batteries, and those DO NOT like to be fully discharged. Hell, the device might not even recognize the battery, if it has really been fully discharged.

Okay...so I went to the shop from where I bought my s3 (Orange shop) And they told me to send it to their service and I did so...as I still had it under warranty. It was there for exactly a week and today I got it back. They told me they replaced the battery (which they actually did...I checked that) and the power connector from my phone. The battery it's still not good enaugh in my opinion. Immediately after I got it back...I turned it on and it had 79% battery. In about an hour it went down about 25% (so to 54%) but I didn't used it havely (note: the mobile data option was on). I really do not know what to do. I asked someone and they told me to send it again because this is not normal.
My s3 is running stock 4.3 and used to last waay longer back in the day.
What should I do? I literally got about max 5 hours of use before I sent it and I am afraid this will happen again. I do not even want to think what is going to happen if I listen to music for example.
I turned the phone off a few hours ago...then let it charge up to 59% and then stopped because I had to leave. I used it moderately for about 4 hours and 51 minutes (as my phone says) and i have about 2h and 15minutes of screen on time. My screen is using 50% of the battery and also Android system is using about 17%...chrome 12% Android OS 7% and I think everything else is less important as they use 7%<. After those almost 5 hours...while the mobile data option was on all the time I am at 14% battery.
What do you think? Is it good enaugh? Should I send it back? I really need help!
I am waiting for suggestions.
Best regards!

I think so, the fact that you have the screen on top of Android OS (and not the other way around) pleases me. You had your screen on for 2h15m, of course your battery went down fast
Test it, charge it full, and use it. Normally.
Do this for 2 or 3 days, and check how the battery lasts
When my battery is getting low, I've started to notice recently that it never falls below 4%. Instead of counting down to 1% and shutting off, it just shoots down to 0% and immediately starts the "Power Off" screen. Is this normal? Anyone else's Nexus 6 do this?
I've seen the post about the Nexus 6 that would shut off at 73% consistently and I guess this could be related to a bad battery or calibration, but I was just curious.

I've only ran it down that far once and yes, it shut down at 3%
@j.bruha I assume you know this, but just in case - Li-Po batteries don't really do well with extremely low charge levels. Try to avoid depleting the battery charge level to anywhere close to 0. Most folks recommend keeping the battery level at 30% or higher for longer overall battery life (not the time that your battery lasts from charge to charge, but the number of months/years before you will need to replace the battery itself)
Mine goes all the way down to 1 % and shuts down. I can still use phone when it shows me 2% left. Never seen it shut down at 4%. Discharge battery and fully charge it, Sometimes it does help. good luck.

I think there's a lot of over thought about caring for batteries. I think the best advice is to charge it as it needs charging.
Li-Po batteries don't do well at extremely low charge levels. That's an understatement. They become physically volatile and very actually dangerous to use. This is why when you deplete your battery from 100% to 0%, you're actually discharging from 100% to something like 20%. The battery chip does not let the battery deplete fully and is calibrated to report that 20% as 0%. There really shouldn't be any harm letting the phone shut down at "0" because it isn't 0.
My phone shuts down at ~1% sometimes 2%. It has shut down at 3 once but it depends. I usually don't run my phone down that low, but if I do I expect it to turn off at some point. I would see if you can have it repeat the behavior so you know whether or not its a bug.
