Hey guys,
I'm sure most of you know about the Battery Calibration app on the market.
For most of you, calibrating at 100% charge should significantly increase battery life.
After playing around, it seems that the phone can't seem to "keep" a sustained "track record" in battery life over the days and repeated charging.
Once calibrated the first time, battery life seems to be exceptional. Allowing the phone to die and charging again without calibration seems to degrade the battery life yet again. It's definitely something with the batterystats file.
Also, once calibrated, if your phone is charged (lets say from 25%) to give yourself some extra juice, and you do not hit 100%, remaining battery life seems to suffer.
I've repeated this multiple times as well. Last night, I charged from 25% to 54% and my phone couldn't keep a good charge and dropped to 19% with light usage in about 2 hours.
The Point: Calibrate your battery every time you hit a 100% charge. (For me, each morning). By doing this, I've went from 6-8hrs of total battery time to about 22-30hrs.
I've even managed to squeeze out 2.5hrs of display time as well.
Maybe the dev of the app should add an automated scheduling feature, or one that calibrates every time the device hits 100%.
Hope this helps!
Im going to try this, charge is at 80% so i'll throw it on charger, and then calibrate at 100. I hate how the battery in this phone is so sporadic, i've only gotten 30 hours out of it once. and never again.
Do u sure it affects a lot?

Made a huge difference for me, give it a shot.
charged to 100% and then calibrated the battery, i will update you on how it fairs, and what kind of usage i do. I usually am pretty low on battery by the time im on my way home in about 6 hours.

It varies for everyone; hence "calibration". This gives people the battery life they should be getting.
This usually only makes a (or I should say the most) difference with freshly factory reset phones, or right after flashing a custom rom.

1 hr 50 minutes unplugged so far,

3m 9s Voice calls @ 18%

Email 2%
Only down 10% battery. normally im down roughly 10%/hr when ive so much as used voice/email.
I agree with the OP... This seems like a much safer way to keep the battery accurate, etc. I was told a while ago that the Battery calibration app doesn't work right on the atrix, so I was told to manually wipe the stats in CWM, then let the phone die and then recharge to 100%...BAD idea. Battery seemed completely fried after this, only about 1/4 as long as it did before.
I think the app does work, and it's much safer. I don't really recommend ever letting the phone die though, after what happened to me. Could have been a freak accident, but not taking that risk again!
28h 30m, 46% battery left.
2h display
30m talking
30m plants vs zombies
All I've ever done is charge phone to 100% first charge, let it completely die, and then only charge to 100% at night, with occasional car charger use.
I wouldn't suggest completely decharging battery regularly, it deteriorates lithium ion batteries faster

I never let mine die completely either. Ill usually put it up to charge at night once it hits about 20% or so. Calibrating once in the morning seems to get me through the day pretty well.

This is definitely better than usual. 2 hours in, i was at 80%. now after 5 hours, im at 80%...
On a side note, The phone hasnt gotten hot in my pocket like it usually does today as well.

How long have you had your phone? Mine really didn't start performing well until I had had it for 3 weeks or so. I did a flash to the 1.83 SBF (at 100% battery - equal to a recalibration) and haven't shut it off in like 10 days. No recalibration and I can get at least 18 hours of use (with like 4-5 hours of screen time).
tl;dr - I don't think you need to recalibrate all the time
How do you figure the 100%, since the battery goes from 90 to 100.
Do you just let the battery calibration app beep when it measures 100%?
Thanks.
Which battery calibration app did you download?
Sent from my MB860 using XDA Premium App
I used this app:

As for my phone, I've had it since launch day on at&t.
Another thing to mention: add a screen-off profile using setcpu as well, definitely helps.

Yes, the app will notify you when your phone is at 100%, as well as the text reading "charged" on the lockscreen.

When my phone is fully charged or has 70 or 60% remaining battery it seems to drain as normal, around 2-5% over a 10 hour or so period...
However, I've noticed once the battery decreases below 50% it drains FAST, why?
Anyone else noticed this? Test it for yourselves, monitor the TIME it takes to decrease from 100 to 50% and then from 50% to 0.
Yesterday I forgot my phone in the car whilst going to work. It was turned on however it was sitting all day in the car.
Once I returned from work I was shocked to find the phone would not turn on.
At first I thought there was a problem or some kind of fault. Once I plugged in the charger it started to charge, the battery cut and the phone automatically turned off!
I remember the phone had around 48% battery remaining, no wifi or 3g or data turned on. It was simply idling...
So the question is HOW can the battery drain from 48% to 0% over a 10 hour period without being used???
Should my battery of been ANYTHING over 50% it would only lose a few percent...
Same thing for me. (Samsung Galaxy Note N7000 - stock Android 2.3.6)
Battery slowly decreases from 100% to ~50% and then ~2x faster.
I charged the note on my computer and then switched to the charger (at ~60% of charge).
I'm no expert of battery charging etc. but just remembered my iPhone 3GS discharging faster when charged on the computer than with the charger.
If it's the same for the note, some cells could discharge faster because charged on the computer.
Can someone confirm this (or not) ?
How did you charge your phone ?

Same thing happnd with me, and charging my phone thru electric charger..
So it seems this behaviour happens to several other Note users, why?
It's a problem knowing that having around 50% left in your battery will struggle to make it through the day with little to no use...
Have you people set the wifi to turn of while the screen is off? This is unnoticeable in the daily use, but increase the batterytime massively. The setting for this is hidden, you have to push menubutton while in the wifi-settings.
Here I thought I was only imagining things about the battery life dropping faster once it has reached 49% or less.

Haha, nice to know I'm not the ONLY one facing this bug...
I can only hope Ice Cream Sandwich solves this battery drain issue.
Hmm, i think i have the same problem, but i'm not sure. Will get back to this thread when i've investigated a little bit.
This may be a typical samsung issue.
I remember when i had the spica , the battery percentage lining in kernel was totally wrong. I think its done on purpose so you would feel like you have more battery life. 75 % of the battery drains slow. And the rest 25 super fast. Can be fixed within kernel.

I believe its just a placebo effect. Battery usage always depends on so many factors its a pain to even consider starting looking for the issue.
Being on stock KK5 not rooted, i cannot report the same. I only see "fast battery drain" at the last 4-5%. If you feel its an issue, could you post the firmware version you are on and the battery stats graph just for reference?
Placebo or not its something I can definitely feel on my Galaxy Note.

When you get the chance, could you post the battery stats graph please? what we should see is a (lets say) 30 degrees angle and at about halfway it gets steeper.
I know its quite hard to demonstrate the issue, but if you lets say use wifi to browse the first 50% in text only sites and then visit youtube for the last 50%, it won't help the test.
A nice way to test it would be to charge it to 100%, then load up a long movie and repeat playing it till the battery is 2-3%. Then post the results.

When the Wifi is disconnected, the 3G scanning will get on. Isn't that defeating the purpose?

Hey there!
I would suggest to load the battery 100%, plug it out, go into recovery and wipe battery stats.
I have to admit that I don´t know exactly what this workaround does, but I read about it in another forum...and it worked for me, my battery status is much more accurate now!

I'm back. I've had the Diagnosis app running for the past hour, and i got some interesting results.
---Wiping battery stats does not help---, a full charge automatically causes battery stats reset.
I full charged mine with the electric charger after fully discharging it without turning it on.
This time i didn't notice any change in discharge speed between 100%-50% and 50%-0%.
Last time I charged the phone it was not fully discharged. Charged it from 30% to 50% then 50% to 75% on the computer, and 75% to 100% using electric charger.
It's just a supposition, but maybe doing several partial charges while using the phone makes the battery % information inaccurate (wrong battery stats?).
[Edit]In this case, wiping battery stats should show accurate battery %. [/Edit]
I had a similar problem, and I think it is to do with some incorrect scaling or measurement.
I was down to 28%, and it seemed to be draining fast even though I was not using it. I rebooted (I love how quick that is after my Arc was so slow). On restart it was at 17% ! The usage graph just did an instant drop.
I also had another occasion where it remained at 100% for 2 1/5 hours of use.
I assume some calibration issues caused the meter to read the battery wrong. I am turning off on the w/e overnight (when I do not need the alarm) to see if a slow (180 mA) charge while off will help. I may even get a decent alarm clock so I can turn the phone off at nights and charge. I spend too much time in the morning checking my email and reading news!
What is more consistent on mine is that when the battery drops to 9% or less the loss is like 1% per ~10-15% and this is with wifi/3g off, phone locked.
I'm back again. I've had some serious battery drain the last couple of days, but i noticed that Auto Sync was enabled. Once i deactivated it it got much better. Pulled the phone from the charger 9 hours ago and i'm at 90% battery left. I've sent some SMS, a few calls and that's about it, but it doesn't drain while it's in standby now, so i'm happy with it.
I have had my S4 for 5 days, battery lasts me only 5-6 hours at best. Moderate useage. Disabled all bloatware and apps I am not using. Not having the Maps issue, also turned off all the air gesture stuff and etc. Should I get it replaced?

What does betterbatterystats say?
I have the same problem, but I get around 2:30 screen on. About 6-8 hours usage, I've been trying different ways of charging to see if it will extend life, I might try to use power saver mode next if I can't find a way to get better life.
I have same problem too. This is day 7 for me since I acquired the device. The first day I thought the drain was from the amount of usage during my setting up the device. But now even after a full charge. It will be down to 92% just sitting in my holster in about an hours time. The battery would drain in about 8 to 10 hours.
The only massive usage in the battery status page I see is the screen and I have set that at lowest brightness and then auto. Im using battery saver as well. Im thinking about taking this to AT&T store tomorrow to see about battery or device replacement.
We shall see.

That is definitely abnormally high battery drain. I get less than 1.5% drain / hour when the phone is idle. So your drain seems to be more than 5 times higher!
It may be a misbehaving app.
BetterBatteryStats, is good because it gives you detailed info on what is consuming your battery.
This is what mine looks like

If you are in a building with pretty thick walls that could drain your battery also due to the phone using more power to acquire a signal. I work in a building that house a lot of servers and notice it uses more battery than when I'm not at work.

This i can agree with, when i visit my parents in the middle of nowhere my battery on any phone every has always died in 3 hours looking for a signal so this might be relevant if you're in a porr signal area.

I'm having this problem too, I don't understand BBS but here's a screenshot of the screen.
I'm tired of this, how can a new and expensive cellphone's battery lasts like 8 hours without even really using it.
My drain was resolved. Android battery stats indicated the screen was draining the battery. BBS indicated my WIFI use was. But neither usage seemed too much.
A visit to the local AT&T store got me a new battery. Albeit some arm twisting occured trying to convince them of the hardware issue.
Yesterday, after overnight charge the previous night, I ended the day with a 72 % battery.
Did a quick charge to 100 percent this morning and my charge dropped 1% in 1 hour. With heavy usage, I sit currently at 72%.
Much better results and happier.

Are you sure? S4's battery is 2600 mAh. It should take about 15 hours or more to make the battery become low with minutes of gaming.. I have S3 mini and its battery is 1500 mAh and it takes about 12 hours or more to make the battery become low.
I can get 5 hours on 60 percent but I gotta be using battery saver with data off when I lock the acreen

Was the battery life always terrible or is it just now?
I'm having a similar problem so I'll use this thread instead of creating a new one. I hope you don't mind.
My battery is draining at a rate of 15% per hour even If I leave it on standby, ocasionally turning on the screen to get a message on Whatsapp of checking the time. It was 100% this morning, 1 and a half hours later, 74%.
After reading on the forums that the cause of the battery drain could be that the phone was constantly trying to get network signal (in cases where the signal is poor, like where I live), I decided to switch on airplane mode. To my surprise, in 3 minutes after this the phone was in 75%. 10 minutes later and I got a 76%. As I write (on PC) it is on 80%.
That's right. The phone started "recharging" without a cable (I know this is impossible, just describing what the display shows me) after I turned on airplane mode.
Any ideas about what might be going on and how can I solve this?
Thanks in advance!
P.S.: It's not the battery itself, as I've bought a brand-new, samsung original battery and the draining was still the same
EDIT: the battery started behaving like this only a few weeks ago. So I'd assume that the signal problem could be helping, but would not be the main reason on why my battery goes down so quickly.

You could try that and see if it is a rom problem.
Otherwise try to borrow a battery from somewhere just to be sure it isn't the battery.
I left the device on 100% and go to sleep.
When I woke up I see 95% so I check the better battery stats and saw that the phone was in deep sleep all the time just minute and half was a wake.
It say the the mobile standby make it.
I think it too much if the device was sleeping
What do you think? I have a problem with my battery?
no, i guess not because i have arond 4 % loss over night in 8-9 hours. mobile signal strenght is also an issue if you have bad reception. but i guess the drain is normal. nothing to worry about. Are you stock or custom? I am on weta with naptime en greenify.
Unless it's a signal issue that does seem high. I get 1-2% over 6-7 hours over night. I'm not using anything like greenify or naptime either. I get that on Stock 7.0 and on Pure Nexus 7.

5% over a whole night and you think there is something wrong with your battery? Assuming that is 6-8 hours I'm not sure why you are worried. It is still on and, thus draining. So, if you let it for 24 hours 15% seems high to you?

Sound just fine to me.
less than 1% an hour is a sound result.
I WOULD KILL for that kind of idle battery life. I HOPEFULLY get my 6p Thursday. I am on the S5 now running MM and sitting at my desk I get 5% or more per hour drain if I am lucky. right now, if I am not on it much, 10% per hour.

Hmm, doing nothing with phone it was 1% every 4 hours on stock. With PN7 its like 1% every 4 hours. This is with about 35 apps installed or no extra apps installed. So if you're seeing about 5% loss overnight for about 6-8 hours, it seems to me your phone isn't deep sleeping very well, cause that means there is a lot of stuff still working in the background. Like i said, unless there is poor signal.
Again this is based on what i see on stock and PN7.

After being on Android since Gingerbread and using Sammy and Nexus devices, while doze in MM and N has brought a lot of improvements in sleeping battery drain, I'd say that 2% over an entire night is unusually low.
Also, many folks do different things to their phones overnight. If you leave it 'on' but turn off your radios and turn on total silence as opposed to just letting it go to deep sleep but leaving everything 'on', you'll see significant differences in drain.
I'd still just look at 24 hours of no use, doze drainage and if you only got 15% drain that would translate to roughly 7 full days of standby. That's pretty good. In your scenario, 3-6% drain over 24 hours of standby/doze is pretty much unheard of. I'm not aware of any phones that typically give users 17-33 days of standby

Also, many folks do different things to their phones overnight. If you leave it 'on' but turn off your radios and turn on total silence as opposed to just letting it go to deep sleep but leaving everything 'on', you'll see significant differences in drain.
I'd still just look at 24 hours of no use, doze drainage and if you only got 15% drain that would translate to roughly 7 full days of standby. That's pretty good. In your scenario, 3-6% drain over 24 hours of standby/doze is pretty much unheard of. I'm not aware of any phones that typically give users 17-33 days of standby

I've been on android only and since the droid X days which was Froyo myself.
My phone is exactly the same overnight as during the day. I rarely ever use WiFi since I'm on TMobile. My phone has to be fully available to me since I'm an IT Admin and that means I'm on call site security reasons 24/7. To me getting 5% a night would be making me search through my phone to find three cause LoL
Im not too sure what setting i changed on mine but when i wake up after 7 hours i'm sitting at 99%
