I'm getting my S3 tomorrow second hand, is there anything I should do to ensure i get the best possible performance from my battery? I know there are apps that can wipe the battery stats etc, is that still relevant on the S3? Any general advice?
Battery calibration was a myth that has been debunked by Google engineers a while ago. It still seems to persist though.
Just charge your battery when you get your phone. You can play with it at the same time. It will just by charge a little slower. After that charge as necessary. Battery life will improve over the first few cycles.
Enjoy your new toy when it arrives

^^ what he said. And then again I was reading on a thread that the starting battery calibration is not correct and needed to drain to 0% and then get a full charge to see better results. I havnt tried this yet so not sure cause everyone uses their phones differently.

i guess a picture is worth a 1000 words... have a look...
more pix for ur eyes ^_^
If your rooted, try battery calibration. Plenty of threads about, and varying methods.
If not, another battery, and if new, ensure charge fully, phone off, overnight, before first boot.

forgot to mention i'm running [Rom]Wanam v3.2 at that time, currently on v3.4, the dark extended areas is me at work where i turn airplane mode on due to serious bad reception at work... sync is on rest of the time for gmail/whatsapp/kakao other than that manual updates on twit and some news apps...
u can see the first jump in the first pic, that was due to me exchanging with 1st spare battery( got 4 + original batt= total of 5)
i dont know if its the phone and exchanging batteries thats causing such high battery losses at the end of the battery life...
plus yesterday and the day before battery goes crazy when it reaches 30-20% and when i go for a restart to freshen things up... the phone wont switch on thinking the battery is totally dead... i put in the new battery and its @ 100% ... switch back to the old battery to see where the 30-20% went... it wont start...
now im thinking... keeping 1 battery in the phone with a charge from 0-100% actually takes the phone all the way to 0% but exchanging the battery wont...
how am i supposed to use the full potential of the batteries...

been using this app since my old sgs, it sure works and have been using it ever since...
tho in the [Rom]Wanam ... install procedure says that its backing up the battery stats and this lead me to think that a batt calibration is not needed... or am i wrong to think so?
If you change batteries, all previous data will be irrelevant, and you need to calibrate each time. You can do things manually by installing battery monitor widget, charge to 100% AND until the mA reaches zero (Voltage spills be approx 4200mV). At this point, quickly delete battery stats (menu / stats /) and immediately unplug.

Top help with monitoring, You can config the update rate and widget content so it shows mA, %, mV. Also have alarm when stops charging (if configured).
There is also an option for calibration, but I only use this method when done above first. Never discharge to zero, 1% min.

Thing is, what's the use of having spare batteries if this will happen on each battery swap and having to go thru calibration means having a charger nearby...
and by 0% i didnt actually mean 0 but till that 1% turned the phone off
if what u said is true, then i guess i need some kind of script to help and keep the batt data even after swapping.. based on 1 good calibrated file swapping batteries should start from a certain point even if the batteries do lose some of their charge but continue to moniter things as they were... i dunno if what i said makes sense... correct me if i'm wrong
Not really 100% sure, but sure I have not always calibrated after a battery swap in the dhd..The previous battery was calibrated and performing well, and the replacement would have been very close to 100% charge. I didn't notice any irregularities in the battery data, or battery drain.
So I suppose a good bat stats file should help the phone showing relatively "accurate" data after a battery swap, if they're both "conditioned" (gone through a number of charging cycles, not straight out of thre box)
Maybe I could be wrong, but based on past experience.

thanks a lot for ur replies ^_^ much appreciated
anybody else wanna shed some light on this ?
This is a good app for more info on battery drainage.
http://forum.xda-developers.com/showthread.php?t=1179809
Have you tried different radios/modems for better reception? if your phone is struggling to get decent reception its going to use your battery.
You could try changing to 2G only in wireless settings. used to help me alot.

i'm already using it steve, thanx for the helpful info ^_^ , tho it has nothing to do with my strange problem... before going to work i switch to 2g coz i mainly use it for calls so after work is done, i wanna have fun with the phone so its back to 3g... i hardly have reception as i mentioned before is due to really thick walls and working underground in some rooms... its just common sense... plus im on latest modem and its actually performing better than other phones (nokia,BB,moto,iphones....) at where i work, 5 guys got convinced and got a sgs2 coz of mine lol
I've been using my s3 for the past one week and my device shows 99% assoon as i remove my charger! i've tried changing the rom, erased my Battery stats, recalibated my battery using playstore apps. even though it shows 99%. please help! by battery life is worst!
All GS3's are like this only. The battery actually never charges to 100. Its purely cosmetic.
Please tell me you've actually tried searching for this before posting since there are literally dozens of threads and discussions revolving around it.
Physically it's very simple. If a battery is 100% full, it's as full as it can get. This is not true for everything but for most consumer-related stuff. (Airplane turbines, reactors and other industry-machines see it as a maximum value for long-time usage but can go quite a bit above)
If you unplug it, your phone starts draining battery since -surprise,surprise- it needs power. So the battery cannot stay at 100% if a (however tiny) part has been removed.
Phones that remain at 100% after unplugging for some time are lying to you to make them look better. And you don't want a manufacturer lying to you, do you?

Better check of you have rogue apps in the background or your screen brightness, my batterylife is quite good (about 2 days with medium/heavy) use. Running stock firmware.

That's perfectly ok. Relax Been discussed here already...
PS absolutely no need to calibrate the battery
This happens to me as well but don't fret over it.... Calibrations should be done regularly but not overly or it'll stress your battery more than necessary.
You do not calibrate your battery regular the year is 2012 not 1995 .
Battery auto calibrates itself use it ignore it .

I'm amazed how people can get nearly 2 days with medium usage. Do you have any apps installed? How many hours screen do you get?
It seems it's pot luck with battery life..
Hi
I just received my new 2000mAh Samsung replacement battery. When I say "getting the most" from it, I mean get the best performance and prolonging it's life. Now I've read about many myths regarding Li-ion batteries. Some say that upon first use you should do a full discharge and recharge cycles for at least 5 times. Some say that you should never allow it to discharge below 50%.. Some recommend to charge it only when the phone is in shutdown... Some say you should not charge it all the way to 100%...
What do you guys say based on your experience? Does this bat need a full charging cycles? What is considered a full cycle? Is anyone here using this bat? Did you notice any major difference compared to the stock bat?
Thank you for your cooperation

Mate there are tons of information regarding battery life here on XDA. In most cases it depends on your ROM and Kernel as well as usage. You can do a search but for starters you can try here http://forum.xda-developers.com/showthread.php?t=1909996. I personally have the 2000mAh battery and yes there is a very noticeable difference compared to stock battery. It is probably best to fully charge your battery and let it run all the way down for at least 2 cycles. If you want to get more technical and tweak settings you can visit the thread I posted or do a search if this is not what you are looking for.
Just do what I do, don't care. Of course I don't want my phone dead around noon. That's why I use betterbatterystats, I just look for wakelocks and processes which eat up battery. That's it! It obsesses you if you always want to improve. Getting rid of wakelocks and stuff is all you want. Trust me, focus on not caring about the battery, find a ROM you like charge cycle it a few days and battery is fine.
I was really suffering from massive battery drain....see here - http://forum.xda-developers.com/showthread.php?t=1933012
ive now found out that i am having a very wierd problem...My rom is showing some 30% battery while 4ext shows 50%......Sometimes it is exactly the opposite....Once i discharged my phone to 2% (rom reading) and when i saw in recovery it says 17%....
I have completed many many cycles of battery from charging to full....and discharge to 0.....Also i used the battery callibration app SEVERAL times!!!!........But nothing seems to work...
Can somebody help...Please

Did you try to delete battery stats? Or use an app to improve battery life?
I have the same issue too when booting into recovery. I don't worry about it. I suggest the same as Ramjet in your other thread.

I had this issue with my old battery and old charger,
Now I dont use my phone while charging , I charge other batteries with the wall charger while using other ones and everything is fine now.... battery % seems to be same in both android and recovery.
I have that same issue too. Lol maybe the recovery can't read the battery correctly. It'll show up higher in recovery and then when I reboot, it will read the same way like in recovery. Tried numerous batteries with the same result. Although I havnt tried battery calibrating. Ill give that a shot.
Is there any solution ??
Try klect's solution and go into recovery, wipe battery stats. Then let your battery drain and die. Then charge your battery back to 100% with no interuptions like pulling your phone off the charger too soon. When you wipe your batt stats you are getting ready to recaliberate your battery. After you let it charge to 100 percent. Let it drain to 0 a couple times to recondition your battery.
You do know that the evo 3D gives around 3 hrs of screen time dont you? even on stock rom on normal usage. If you have the wifi on all the times you'll get around 2:30 maybe 3 on a full charge.
Your battery certainly is draining faster than usual but have you tried keeping it idle and seeing what kind of drain you get? From that screenshot in the other thread it seems like your phone is getting some heavy wifi browsing or something (and do check if facebook or email apps are the culprit. Having push email on drains a lot)
And the recovery/rom reading wrong stats happens all the time. just recalibrate your battery like these good folks here have already suggested
Yes i keep wifi on all the time...
But once i kept my locked for abot 3 hours after full charge...when i unlocked it showed 99%...i was happy and i didn't do anything just surfing my screens it dropped very very fast to some 70 % !!!!
Also please hit our thank you buttons please. Even if you didn't get the exact answers you wanted. It's appreciated for helping one another.
you really should check your apps battery usage using one of the apps ramjet73 told you about
ramjet73 said:
There are a bunch of tips here.
Usually that kind of drain is caused by an app. Try running a stock ROM for a day or two and see if the issues go away. Or use one of the battery monitoring apps (BetterBatteryStats, SystemPanel Standard, Battery Monitor Widget) to determine which app is causing your drain.
It may take some work on your part to isolate the problem since there is no global solution to battery problems.

top culprits are mostly facebook,email exchange,google maps and pretty much anything that syncs alot
Also try using you phone on min brightness auto brightness is also a battery killer
I cant beleive no one asked you this but which kernel are you using? And is it overclocked?
I am on mwakious 13.1 default...no changes to it
I know that many people will tell me that with new batteries it doesnt matter, but I need to know anyway, because nobody seems to be really sure.
Think of this as a research.
When you buy a new phone, what do you do first: let it drain the initial battery charge or fully charge right out of the box?
How is your battery life (considering what you did)?
Thanks.-
I usually drain the initial charge
Sent from my amazing Nexus 7 using xda developer's app
I usually charge it and then drain in on the first use. It doesn't have an effect on the batteries, its more of a way to calibrate the device to its battery. But I don't really think it makes a huge difference. Your battery life early on is usually bad due to all the time you spend setting up a new deice.
