[Q] Battery Calibration

Hey I've read on other forums about these battery calibration apps and whatnot, just want to know if anyone has used them and know if they really do work? The wife and I both have the Dinc2 and i loaded andybonestock on both of our phones.. i use my phone like crazy and she barely uses hers. i put drellis's 21 on and UV 50 and within 15 min off the charger i'm down at most to 98 battery and she's already down to 90. her battery drains rediculously faster than mine and they're both the same exact rom's and kernel specs. Will these app's actually work or is there a real/better way to get hers working better?

Use battery calibration from the market and follow the instructions to a T. Her battery could also be defective. Try the calibration first though.

that's what i'm trying to do. I have it charging right now, at 84% then im going to run it.. just wanted to know if there was any proof it worked or any other option

I left my inc2 get charge to 100% and then use the battery calibration,i notice that my battery goes down from 100% to 97% in just 5second,the battery life is good after goes to 97%,but im not sure why goes down to 97% that fast.

Just a heads up, that is normal, your battery will never stay at 100% it doesn't charge to 100% unless you bump charge it (and that is bad for your actual battery). Having it drop anywhere from 97% to 92% is common, after that you will notice a substantial slowdown in battery drain unless you are heavily using the phone.
I added a picture of my battery life as an example of the length I am getting from the ICS Rom I'm currently using. I have my phone oc'd to 1.4ghz and uv -25 across the board. This screenshot was taken after a day full of phone calls ranging between 3 minutes and 20 minutes, moderate browser usage, moderate facebook usage and lots of texting.

Ya I knew it wouldn't stay at 100 at all but like how mine would be at 97 after 15min and hers at 90.. it just didn't add up.. she rarely used her phone and only had about 6 hours of charge, while my battery with excessive use had enough battery to last me about 16 hours. I reset battery stats and then bump charged her phone. Now its fine

glad you figured it out.
careful on bump charging, it decreases the life of the battery itself everytime you do it.

I personally don't use the apps. I've had the best luck with charging to 100%, power off and charge till green light, unplug and do one more time, boot to recovery, wipe battery, power up and unplug. That's just me though.

That's what I did to remove battery stats.. read up on the app and realized its the same thing as doing it in recovery

Charging to 100% and then powering off and charging again IS bump charging, that is bad for your battery itself, it takes away life on the actual battery everytime you do it. I said this above. You may be getting an extra half hour to an hour out of your batterys life but you are decreasing the amount of times it can actually hold a charge each time you do that, therefore ruining your battery for a tiny bit of extra battery life per charge.

I'm quite aware of what it IS. I also didn't say I do it every charge. I also know that some say its not good. I also know some say smoking can kill you. I also know I've done it on other devices with no problems. And I also didn't say for anyone to do it. I only said what I do and what has worked for me.

The smoking analogy doesn't really relate, smoking can kill you but doesn't always, bump charging for a fact decreased the longevity of your battery hence shortens the time before it does not hold a charge anymore and you have to buy a new one. I made a factual comment, I did not need a condesending response.

(UVDLI6 JB) Sudden Battery Drain

So I am running UVDL|6 for some time now which works good (not great but good) and this morning I woke up to find my battery completely dead. When I went to sleep it was at a decent 55% now I highly doubt that without any use the battery just drops to 0%, So checked my battery stats and it says Android System at 70% use.. which is pretty high for an idle phone. Any ideas? Or any software I can use to pull out the culprit because Android System has so many subsets to it that it makes it really hard to pin point what causes it.

You will have to reproduce the problem, but try GSam Battery Monitor.

Reproduce the problem? Well I was a sleep so maybe ghosts were messing with my phone, I'll ask them nicely...

I think he means you need to put your phone in the same spot when you go to bed and see if it does it again. No sense in trying to fix a one time problem.
Battery stats were gone when you started the phone up I'm assuming. Good reception where you placed it?

Been happening to me on LI7 lately. Originally it was great on battery life, then all of a sudden I started getting insane battery drain from the Android System. I haven't really taken the time to diagnose it yet, but I need to. It gets really hot randomly sometimes then cools down and the battery just starts draining away really fast.

I saw someone mention deleting or renaming gsiff_daemon in /system/bin to solve this.
Theres a thread dedicated to the subject as well, though ive yet to actually go through it.
Anyway give that a shot and lets all hope they Completely fixed the battery issues in the final release! (Its not all from one thing in my experience with the leaks, but from multiple issues)
Sent from my SGH-T999 using xda app-developers app

Ill add my stock experience for reference as well as if anyone has a fix. I'm pretty happy with battery life coming from a Vibrant but what I notice is that usually there is minimal drain during the night ,however if I get an SMS the drain will be maximal.Like 30/40% Almost like the screen went on and never shut off but it doesn't seem to be the case. This is on the stock messenger App. If I don't get an SMS it will usually drain from like 99% to 96% roughly. Didn't mean to threadjack OP.

Have you tried running Better Battery Stats to see why the phone isn't sleeping?

Yeah battery stats were probably from when I turned the phone back on...

Battery Issues

I started running into some battery issues earlier today. I was on AOKP without any issues and one day the battery just started draining very fast. I went from about 50% to 15% in a matter of an hour. That night I slept with my phone charging and it did to get charged passd 54%. And it's charging very slow too. I thought it might be the ROM so I flashed Slim Bean. But it is not heling at all.
Anyone have anything similar going on?
What can I do?

Try calibrating the battery and go like 2-3 charge to discharge and see what its like afterwards

Will do. I'll post back

Yea it takes a few rundowns to get into the sweet spot, I thought I was getting horrible battery life till someone suggested that to me now I get about 32-33 hrs on a charge. Which I think is about prefect, I don't game on it I just use everything else all the time. I have ps3, xbox360 & psp for gaming
Sent from my SGH-I747M using xda premium

Well it's been charging for about 6 hours now and it won't get past 54%

I let it charge all night and when I woke up it was finally at 100%. I left for class and unplugged my phone at 7:40. 20 minutes later it was down to 47%. Then another 2 hours later, it was at 11%. Obviously it is draining far too fast. Will AT&T replace my battery? Or does it look like I'm gonna have to buy a new one?

What I normally do is charge it to 100% then boot into recovery and wipe battery stats. Reboot and don't unplug the phone until it again says that the battery is full. Then run with it and see if it helps.

Go ask them I don't see why they wouldn't replace the battery, it does sound like its shot that kind of drain isn't normal at all
Sent from my SGH-I747M using xda premium

I had the same issues with not getting to 100%. Seems like leaving it on the charger for another couple hours (overnight) got it there.

So I went to the AT&T service shop yesterday and she took my battery and put it in a different Galaxy S III and it showed the battery was charged 97%. In my phone, it showed 23%. She told me that it had somthing to do with my phone being rooted. She said the software on my phone was being "tricked" into believing that the battery is a lot less full than it actually is. She told me to unroot my phone and flash it back to stock. So I did that yesterday and it is still no better. I don't know what to try.

Wiping battery stats doesn't help battery life... Something i learned a long time ago with my X10

My Android system is almost always under 15%. Seeing it that high is alarming. I assume you've tried full wiping and changing ROMs?

Yep. I must've flashed my phone to stock at least 10 times now. Ive tried rooting and Unrooting, clearing my flash counter, I really don't know what else to do.

Thought I'd try installing CM10 just to see if there would be any difference. Screen Brightness shows up as my highest percentage on the battery usage and Android System is much lower on the list, but the battery is still not charging or discharging correctly.

I would unroot and take everything back to stock, then go back to the AT&T store you went to before and show another service rep that the phone is messed up and see if they give you another one.
Good luck

mrb1946,
Even though your S3 is reporting percentage values as you stated....the PHYSICAL battery did not drain from a real 100% to a real 47% in 20 minutes. It can't actually physically drain that fast. It would be on FIRE! So, either the calibration of the rom/software or the battery itself somehow messed up.
Also, during that time...was the battery/S3 HOT? That physical evidence would account for some of the drain if it's coming from a rogue app or misbehaving rom component. Did you post a battery drain graph? And were you monitoring the cpu activity during these high drain periods? I mean...periodic checks to see if your CPU is stuck on HIGH freq and if you have any wakelocks shown under the battery graph.

If this problem is still occurring, here's a thread explaining a possible drain from android system. http://forum.xda-developers.com/showthread.php?t=1827087&highlight=android+system

Battery life Replenished!

I was on here trying to find a way to reset my battery's memory...and I found it! Its so easy. So during the day, drain your battery to 20%, and plug it in all night. When you wake up, take off the back, and take out the battery for 3-4 minutes. Then, put the battery in the phone and turn it on. As it's turning on, plug in the charger. Leave the charger in until the phone says "charged" or has the battery icon showing full. Unplug your charger, and say Hi to a factory battery.

2% in 17 minutes....this is phenomenal... at least for me.

It is just an overcharged battery...
Sent from my SGH-T999V using xda app-developers app

What do you mean?
AT&T Samsung Galaxy S III

my understanding is that the battery is never really charged to 100% (even if you see 100% charged in the software).
it is a way to prevent overcharging the battery (because on the long run, it is decreasing the battery life and performance)
So, what you are doing is that you found a way for overcharging the battery and the result is that the battery life for the first 100 to 98 will be very good, however it will go back to normal after this step.
Correct me If I'm wrong, but I'm pretty sure that I'm right

Nah, its completely better...
AT&T Samsung Galaxy S III

Lol....you'll have to show more proof than that, even if youre phone confirms what you said.
Matrix is right, I think this is in your head. Placebo effect as its known.
show us screen shots of batterry useage for a week with this technique, then a week with out.
Then others will have to try it out.
Hey if your smart enough (since again your NOT doing anything physically, trust me ) you could write a a little script and make it an app?
Also its been said the battery gauge is really kind of a pasifier for us.
Physicaly there is no way you are changing the state of the battery by just touching the contacts real fast.
UNLESS your batter contacts are totally fried/or oxidized and somehow the friction has cleaned them???
If any thing, you are resetting the battery statistics/calibration and that ( confirmed by google, and a few a manufacturers)
does nothing.
One thing about batteries; the harder you work them the shorter they live, this is why Samsung,htc even apple said the batteries don't fully charge 100%, because if they did the batteries wouldnt last half as long.
But hey keep working on it maybe you got something there! :good:
and just for yucks

Your phone never charges all the way to prevent over charging and help keep your battery healthy for a longer period of time. Some kernels allow you to change this hidden setting from 98% to 100%.
All you are doing is circumventing the system and potentially harming your battery. And unless you keep doing this for every charge cycle it will return to normal.
You may be experiencing a placebo effect because your battery stats have changed based on the over charge. The battery stats data is used to guage your battery life.. This is updated for every cycle and will eventually return to normal on its own.

How can you troubleshoot certain parts of your phone?

Hi All,
So recently I have been having problems with my battery life. It's not lasting as long as it should. However, I do not know whether or not its my data cable, the device that plugs into the wall, my battery, or the charging port in my phone.
I got my phone from best buy, but it was more than 30 days ago, and I have no insurance on it, so I cannot get a replacement without sending it away for at least $100.
Any tips?

Well what battery life are you getting? Get into the Phone settings and then battery settings and post a snapshot of the graph here. Additionally you can also install Batterystat it will give you a full analysis of what's using up your battery power.

I think I may have narrowed it down to the battery itself? I have some battery apps that tell me the health is "good," but what does that really mean? My charging cable is iffy, because sometimes it works perfectly, charging to 100 just fine. However, other times it charges 20 percent in 9 hours. When I used my friend's Note II charger, it worked perfectly every-time. But the fact of the matter is, when my phone does charge to 100 from my cable, I still get not the best battery life, which leads me to believe it's my battery's fault. I am going to test out charging my phone to 100% with my friend's cable tonight, and see what happens tomorrow. I will also get batterystat and report back.
Also, this may be important. When I first got my phone, battery life was AMAZING, really quite astounding. It's just kind of dropped down, like a slope. Not a sudden, dramatic drop, but incrementally.
As for the battery info below, here is what went on today. I unplugged my phone from 100% at around 7am. It is now 6pm. Today, my phone was barely used, just sitting in my pocket with wi-fi on. When I did use it, I sent two very quick emails, played scramble with friends for about 45 minutes total, took a few photos, listened to music from the music player for about 15 minutes, and that is really all I did. I feel that my percentage should be much higher than what it is listed as.

Here's mine as you can see I'm getting almost twice your battery life. I have a few apps that i use everyday which are basically whatsapp, xda, chrome. I don't have many apps that would wake the phone constantly and if there is then I disable them from starting up when the phone is not in use. The best tool you can use for something like this would be rom toolbox pro. It's multiple system tools in one and it works great. I'm currently on Omega V10 with perseus kernel. Also I don't connect to wifi much and network here is weak and on 2G but even though I still get this battery life. In areas with good signal I get more battery life. Also I've dropped my phone twice with impact points on the corner, and just minor scuffs but that didn't effect the phones performance or battery life so I doubt it has affected yours.

Also I've overclocked, my processor to 1.8ghz and undervolted between - 50 and -100. So i get minimal power wastage from heat build up. Also you can set a black wall paper with a dark theme.

Unfortunately, I am not rooted, and haven't planned on doing so ever. Is there anything else I can do to fix my problem? I did download batterystats, and am waiting a few days though to see what it tells me.
Also, I used a different charger just to see what would happen today, and even though its been off the charger for 2 hours, it's already down to 94 percent. So I am thinking that there is either something wrong with the battery, the charging port, or could there be a bug in the phone's software?
I am thinking of getting a new battery, and seeing if that fixes my problem. I'm just so irritated because battery life used to be amazing, and I don't know what happened.

Maybe try a factory reset. Maybe something else has been using your battery.

That's what I was thinking. I will probably do that and report back, before going out and buying a battery or something. Is it possible that, although not reported in the battery info, that an app could be rogue or something or taking up battery? I don't want to do a factory reset and redownload a bad app.

Update: I tried a factory reset. It seems to either be worse or just the same. It's been an hour and has dropped to 97 percent, but I have made a couple of phone calls. But compared to before I did a factory reset, it dropped to 96 percent in two hours while not doing anything.

Keep your phone on charging over night.
Then let it drain to zero no matter what.
Do this 3 to 4 times and then
Leave it for charging overnight.
Then while it is already charging use battery calibration.

Quick Update:
I did another factory reset after I said the initial one didn't help. It looks like it may have helped, although I still have not gotten the battery life I used to have.
I found an application here called betterybatterystats, and have downloaded that. I will use my phone throughout today, and will post sceenshots.
If need be, I will take your advice about charging and draining and charging, and then do the battery calibration.

Here are my most reset battery stats. Screenshots are from the battery setting area, and betterbatterystats
Maybe I am just being paranoid and nothing is wrong? I can't make any sense out of these readings, but I hope someone else can.

first of all change you cable if you are having that kind of issues. Mine in my galaxy ace was having that problem, it was like connect/disconnect without any reason and it didnt charged my phone at all. I noticed it when it was too late, the continous on/off kill my battery. When I say kill i mean it just lasts 15 min in 3g with screen on and it happened to me in 2 official batteries.
good luck!
