[TIP] Battery Life and Calibration

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,
15m 7s display @ 26%
3m 9s Voice calls @ 18%
idle @ 15%
wifi 9%
SYStem 8%
standby is 7%
com.motorola.service.main 4%
launcherpro 4%
android OS 3%
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.

80% battery remaining. 5hr 2m 5s since unplugging.
32% - Display 53m 0s (rare for an even number)
14% voice calls 7m 2s
13% idle - 4h 9m 7s
8% wifi - 4h 52m 5s
7% android system.
6% cell standby
5% swype
3% android os
3% maps
2% com.motorola.service.main

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:
http://market.android.com/details?id=com.nema.batterycalibration
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.

Phone won't charge past 95%

OK so I'm having a issue with the 2.3.4 rom I'm on the latest cherry blurr on the stock radio also stock kernel and my phone won't charge past 95% I'm using transfer recovery to install the rom and also I use fastboot to wipe the phone before any rom install, can anyone tell me why im having this issue and I have wiped battery stats before
Sent from my MB860 using Tapatalk

You have to keep it charging even at 95.it does take some time to charge beyond 95%.

When it hits 95% the charging status shows the phone is unplugged but the phone is plugged in
Sent from my MB860 using Tapatalk

Did you try running CWM and resetting your battery stats? Do that once you've reached 95. Then let it drain completely. Then charge it to F. Then reset the battery stats again. I did that when mine wouldn't go beyond 99.

My ATRIX does the same thing, just leave it in until it reaches 100%. it will take a little while but it'll work.

The phone will charge upto 100% and then stop till it hits around 95% again(not exactly 95% but example). This is a safety feature to protect the battery from charging continuesly.

Alright ill let it charge some more now and report back

Wiped and recalibrated and it's still the same. The second i unplug it goes down to 99 and pretty much downhill for the rest of the day
I think there is a general issue with the battery and GB and i don't think there is a concrete fix yet.

Thanks guys phone charged to 100% gave it some extra time
Sent from my MB860 using Tapatalk

If this happens, there is no need to drain the battery.
Boot into CWM and clear the battery stats.
Download Battery Calibration from the Market.
Start Battery Calibration, (and leave running).
Put your phone on charge with the AC charger. The phone will take a while to get to 100%, especially the last couple %.
You will hear a chime when the battery is fully charged. Leave charging for another 15 minutes, (sometimes if you unplug it right after it hits 100% it drops to 99% straight away).
Calibrate with Battery Calibration.
Enjoy.

Thanks for the tip!

Mine's been stopping at 98. It gets to 95 at a normal pace that I'm used to seeing with this phone, then takes probably 8-10 hours to get up to 98 and then just stops there and won't charge any more, no matter how long I leave it in. The OP said he just gave his extra time and it eventually got back up to 100...but how much extra time should I be giving it? No amount of calibration has helped me yet.
Any thoughts?

what I have done is when the phone is close to charged but not fully is to wipe the battery cache, then connect it to charge. for the first few charges it will stay at 100% for some time before it starts to drop, an it will drop faster then it should and be out of power before it hits 1% but on the 3rd charge it always seems to calibrate itself. I do not drain it fully just till it is pretty low. To put in hard number fully charged it is about 4200mV and so I wipe the battery stats close to 4150 and charge when it gets around 3700
do this a few times and for me at least the battery seem to be pretty well calibrated.

Phon shouldn't be going all the way to 1% I believe. Battery internal safety should shut it off at around 5% to prevent a complete drain which will ruin the battery. If you are seeing 1%, that would lead me to think you are not calibrated properly.

More or less.. for one, though, the battery calibration app should be doing the same thing as wiping the stats in cwm. And even still, my battery will never get to 100 no matter what, so I can't really wait til then to calibrate.. I've tried forcing earlier calibrations but to no avail

Try charging with the phone off overnight, turning it on while still charging then calibrate. Hope this helps.

Thanks, I'll try doing that. I think I'm gonna let it discharge almost all the way, then turn off and charge while that little battery icon is the only thing on the screen. I'll try wiping again at the end, and let you guys know.

Atrix not charging past 88%

As of Saturday evening, my phone will no longer charge past 88%. Earlier on Saturday, the phone was charged to 100% in my car. We lost power and the phone ran down to 3% before I was able to charge it again.
After charging over 8 hours, the phone would not go past 88%. Any ideas?

I have not tried that. Weird thing is, the battery calibration app reads 4196mV at 70% while charging and ~4200 while at 88%.

Just go to CWM recovery and wipe battery stats. Do a few charge recharge cycle. It should be OK.

Sent from my MB860 using xda premium

Charge to 88% or until you notice it not going any further. Turn off the phone. Plug in the charger and wait until the battery display shows. While the phone is still plugged in, remove the battery. Wait for it to boot up and show a no battery icon (or something like that). Once it does, put the battery back in and leave it for about 30 mins. When you hit the volume buttons, the display will show between 5-10% charged. Anyway, after about 30 mins, turn the phone one and it should show 100%. Re-calibrate the battery after that using the app or recovery.

Are all android batteries like this? I've never had a device with such finicky battery stats. I too have the 88% problem and i feel like im recalibrating every week. I will try again.

I don't think they're all like this..but I know its as annoying as F***. Every morning almost i'm doing the "battery pop out" trick just so that it'll read full. It would be different if it read 95% or something and stuck there for awhile until the battery caught up to the actual reading..but it doesn't. The battery continues to drain at a normal rate, so you basically lose however many % you had initially.
Definately annoying..

Mine did this before and what I did was run it all the way to 0% and it cuts of and will not start, then charge it to 100% with the power off and and then boot it up. Work like a charm for me.

do you have the same battery issues on your galaxy?

So I've been sitting at 1% for the past hour. Been playing games, have wifi, bluetooth, GPS all turned on.
Thing will just not turn off!
EDIT: Right as soon as I post this, it turns off. Over 1 hour on 1%.
Will recharge tonight and hopefully it works right.

I had this problem for a while but you should know that it will fix itself eventually. The phone is fully capable of re-learning the limits of the battery and after several days will begin to display the correct charging status. Mine took about a week to start displaying 99% in the morning.
This happened after I did the complete discharge, charge, pull battery, charge again, then boot procedure. It was fine for a couple of days then started displaying 82% as a full charge then slowly got better. I'm fairly confident that I'm not leaving anything on the table in terms of capacity either since with moderate use and turning off wifi when I leave the house I'm getting about two days of charge.

Download from market app called Battery Calibration.
Open it and connect your phone to the charger. When you have 100% status, and ~4200mV click Calibrate and unplug your charger.
Then set the LCD Brightness to max, set timeout to never sleep or just use your phone to fast discharge it(that doesn't need to be fast and doesn't need to be slow it just need drop to 0%).
Let it automatically die because of low power, and then charge it to 100%(you can use battery calibration app to see the voltage, around 4.2V it's max).
After that your phone should have a much better battery life.

To recalibrate the battery go to the dial pad, and input x#0228# and a battery status screen will pop up, giving you some information about your battery and such, tap the Quick start, the screen should go off, then come back on might have to wait few secs. and you will notice your battery % might of changed. try doing it a few time until the % stops changing and give you a "real" battery %, then fully charge the battery. should fix any glitches with the battery being read incorrectly. if it doesn't work might mean your battery had it!
From my experience my battery was on 60% after few hours of use, then I recalibrated it and it went down to 20%, fully charged it now my battery lasting a lot longer than before

At least do a battery pull. Don't bother with apps and scripts that wipe battery stats. Do a pull, inspect for leakage, swollen , or damaged areas.
