Battery meter is way off - Vibrant Q&A, Help & Troubleshooting

My battery meter is way off my actual batery level? When I have 25 percent, the battery meter will show over half?... I have tried the "recalibrate your battery" tutorial...however it does not work..
I am running stock android 2.1 please help
Thanks, mike

Are you on the stock vibrant firmware? If you are, there is nothing you can do, the battery icon just sucks.

1. Wrong section
2. There are battery mods to correct this
3. I kind of like it that way. Placebo for awesome battery life
4. What's a SGH-T959D?

Canadian Telus Fascinate (Vibrant, with Normal North American 3G instead of AWS. )
Basically, Captibrant.
But I call it the Fascibrant, since telus calls it the fascinate but it's really a modified Vibrant.

"Battery recalibration" can cause the problem that you describe. I have written a technical description of this at:
http://dl.dropbox.com/u/12962476/Battery_Conditioniing/Battery_Conditioning.pdf
It is likely that clearing your battery stats and then rapidly discharging has biased your battery stat tables away from the reality of a normal discharge cycle. If so, that condition will correct itself over time (days or weeks). To correct it more quickly, I suggest that you discharge your phone completely and then clear battery stats as soon as you plug it in to charge. (That is, discharge completely, plug into charger, boot immediately, then clear battery stats immediately.) Then just use your phone normally and the battery stat tables will rebuild themselves over a few days according to your particular usage patterns. The battery meter should become increasingly accurate as the tables rebuild.

HOW TO: Solve Battery Life Issues

***NOTICE***
The ROM Manager version of CWM does NOT wipe battery stats properly, as with many other things. What you need is jt1134's version of CWM that is all happy and works and stuff.
You can find his happy CWM here. And here. And also here.
And here.
Big thanks to LegionTHEFecalExcretion for the heads up on that.
***END NOTICE***
NOTE: On current DL30 and EB01 ROMs, you will not see battery life like you did on DL09 with undervolted kernels. There are NO undervolted kernels as of yet, everything kernel wise with Froyo ROMs in very much stock. These steps will improve your battery life in comparison to when you flashed Froyo, but you are not going to see spectacular changes in battery life up to what you were getting with undervolted DL09, etc. It's just not possible until we get undervolted kernels and Froyo matures for our device, development wise.
Hi everyone, I've been seeing a lot of threads about bad battery life, whether switching to Kaoscinate, Vanilla, or DL30. Stop it! Just kidding. There is a simple process everyone should follow when switching between different enough ROMs, like AOSP, CM6 and TW Eclair and Froyo. This is how you retrain your battery.
1. Charge your battery to 100% (when it gets there, let it SIT there, your phone is NOT reporting correctly).
2. Reboot to Recovery and Advanced -> Wipe Battery Stats.
3. Reboot, and use your phone until it is VERY low (5-10%, you can let it die if you want).
4. Charge your phone back to 100%
5. (Optional) Power down, then power on phone. (Thanks goes to BrwnSuperman for this suggestion, give it a try!)
Your battery issues should be solved. This needs to be done every once in a while, especially when switching between different ROMs and OS versions.
User dalrym05 posted this alternate method for retraining the battery on page 4 as well, so I thought I would share it here in the OP. I'm posting this as a USE AT YOUR OWN RISK method, as I have not tested it, and am not quite sure what the *228 steps for it actually accomplish and have to do with retraining the OS battery reporting, so I'm leaving it quoted to dalrym05 for the time being.
dalrym05 said:
Here were my steps to better battery.
1.*228 option 1
2.*228 option 2
3. Run battery completely dead to 0%
4. Plug in and boot immediately into cwm
5. Wipe battery stats and dalvik cache
6. Reboot and let charge fully before unplugging
7. Completely discharge again and fully charge again.
After this you should notice a very nice increase in battery as I did. My battery life is back up to par with eclair.

NOTE: I did edit his post to make it a little more clear. I'm slightly anal retentive that way.
HybridByNature had an excellent suggestion on page 4. If people have good tips and tricks for maintaining good battery life, and they are easily reproducible, then I will gladly add them to the OP here. What works for you?
HybridByNature said:
This might also be a good place to add tips & tricks to extending battery life.
IE
-Close programs that you aren't using.
-Don't leave your camera or navigation running in the background.
-Turn off WiFi & GPS etc when you aren't using them.
-Don't run your screen at full brightness if you can help it.
-Figure out what uses more battery life than other things:
Pandora, internet browsing, downloading, camera/camcorder, Angry Birds etc.
If you are rooted, try and narrow it down to the best kernel/theme for your situation. I've found that I have better battery with a non-voodoo kernel but the performance increase is worth it so that's a trade-off that I make.
Let's hear from our readers: What is working for you?

Would not surprise me if this is all it is. I have turned my phone off at 5% for an hour and turned it back on without charging and then it showed 45%. I know when batteries are low letting them sit a little bit can help, but not that much.
It is just being reported inaccurately by the OS.

Yes, but not as a thread, it gets posted in everyone else's "Why does my battery life suck ass" threads, so I made this so maybe people would see it and try it before posting another useless question thread in Development.
Definitely works though. Did it yesterday. Good post. It has been posted in other threads ... but I think we all know people don't read through everything very often.

I have the battery charger and 3 batteries, I always run my battery low and leave it in the charger for a day.
I did this last night and it didn't work too well for me.
Also, when I go to wipe battery stats in the recovery, it doesn't tell me if it wiped or not, just goes back to the advanced menu.
And also, should I be concerned that when I cold boot into the recovery, it doesn't appear to be CWM? It says Android recovery...I know I have CWM recovery installed.

Wow same here..I just took mine off the charger bout 10 minutes ago and it's at 95% now. I guess I'm gonna let the battery run completely dead and charge it and see what happens.
I did something similar. I charged to 100% while it was on, removed from charger then powered off. When phone was off I plugged charger back in and waited til it was at 100% then unplugged again and powered on. Waited until phone was completely on then unplugged again and connected to charger. Waited til it was at 100% and while still plugged in at 100% booted into recovery and wiped battery stats. Then rebooted phone into OS and unplugged. I had tried this previously with DL09 and it helped a little. Last night I wanted to see how my battery would drain after doing this. With WiFi on and I got about 10 emails during the night, from 8:30pm to 6:00am I lost only 13%!!! Previously I would have lost from 35 to 40%. ymmv

This is a proven technique, and it takes patience. Seeing the battery drop from 100% down to 95 or 96% after unplugging is normal behavior. I've done this already. Left my phone unplugged overnight and lost 1% battery. If you're too impatient to take the time to do this, that's your loss. You'll see the battery life "improve" over the course of a few days as the reporting gets more and more accurate.

I agree with supplysidejesus. This is a standard practice and should be done with each major rom or kernel install. This leak hasn't been put long enough for most of us to know what our expected battery life will be yet. Give it a few days for your phones to adjust.

try disabling gps in the notifications, that worked for me, but once i turn gps on again, it will drive up to a high percentage.

battery jumping to 0% too soon

i guess a picture is worth a 1000 words... have a look...

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.
https://market.android.com/details?id=ccc71.bmw
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.

Strange battery problem help plz

My phone drains the battery very quickly from 100% to 1% but after reaching 1% it can be used for hours.Last time after the full charge battery dropped from 100-1% in about 2 1/2 hours of use on WiFi but after that it lasted for more than 13 hours on 1% but the Network data, Bluetooth and WiFi was off.
Currently i am running CM7 stable (battery fix is also applied) i was also facing such issues on the stock 2.3.4.
maybe a battery re-calibration can solve this issue?

I bought my Atrix 3 weeks ago. My previous device was also another Motorola, Milestone.
When I first started to use Atrix I found that the battery was draining so quickly even I didn’t install any apps yet. It was becoming 1% in 70 minutes with full display and running default apps.
I tried to full battery several times, did factory resets and finally went back to shop. The shop replaced the battery with another new one.
Still it happened same problem. Then they changed my device with another new one. It was same, too.
I would give it back to shop but last time I decided to discharge it until it turns off.
At this point I found that discharging takes long time after it became 1%. For example by heavy using it becomes 1% in 70 minutes, then it takes at least 200 minutes more even I watch videos via Youtube, play games etc.. It means in total it takes at least 4,5 hours with full display and heavy usage. That’s OK for me as battery life.
But I want my battery meter show correct percentage. Then I can be able to know when it will turn off.
I tried battery calibration several times. I search a lot about this problem but found nothing. Probably people thinks that their battery life is too short.
So cannot find solution.
Summary: My Atrix’s battery meter immediately drop to 1% and then runs 3 times longer than previous 99%. PLEASE HELP ME TO CORRECT MY BATTERY METER DISPLAY.
Do you think that your battery fix way helps me?

I don't know. I bought it, and unlocked it directly, then flash CM7 Rom, but noticed that the battery drain very fast. However, after the indicator becomes 1%, I can still use rather a long time. I thought it was an error on battery meter, but I can't make it display correctly through calibration.
Now if the battery is fully charged, I can still use rather a long time after the indicator becomes 1%. But after the battery drained, it can't be charged completely. It really disappoints me very much.

Ya that's the same problem i have i think its something to do with phone recognizing the mah capacity of the battery if u can see the charge-full-design in sys/class/power-supply/battery/charge-full-design u will notice it showing only 500 which should be 1880 that's why our phone drops and charge quickly according the capacity its getting from charge-full-design.
This value can be changed on other phone but for Motorola i have not found any tutorial or app to do so

And for charging don't take off the phone from charging on 100% bcoz when the phone battery meter is showing 100% its battery mv is less than 3900mv and if u keep it on charge after 100% battery mv value will gradually go up to 4200mv which is the actual capacity of the battery.

Oh, thanks. The value in sys/class/power-supply/battery/charge-full-design is just a result, representing the battery statue. So the key is that the battery capacity can't be recognized correctly by the phone. I just test another battery, and the value 1880!
But the former battery doesn't look like a fake one. Actually, I bought them together. I can't understand.

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.

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

[MOD][XPOSED][2.3+] DisableCriticalBatteryShutdown - v1.0 [ABANDONED]

DisableCriticalBatteryShutdown
(for Xposed Framework)
What?
Disables the Auto-Shutdown when Android detects a critical battery level
Why?
This is to prevent the auto-shutdown when you have 1% left of battery. It is useful for calibrating your battery by draining it completely, using Chinese Branded Batteries with terrible battery percentage detection or even lengthen the life of a phone with non-removable battery with terrible calibration.
Compatiblility
Not working on 4.3+
Tested only on AOSP 2.3, 4.0, 4.1
This project is abandoned, I will not add support for any other ROMs.
The App has no interface. It only shows a notification for the attempted shutdown (shown in the attachments)
Disclaimer 1
I am not responsible for any damage to CPUs, SD cards, Internal Storages, or other failures that happened after your battery became flat and your phone abruptly dies.
By choosing to use this module, you are fully aware that this can cause damage to your phone especially when writing data to the SD Card or Internal Storage.
Disclaimer 2
Lithium-Ion batteries should not be drained everyday over a long period of time. Doing so WILL decrease the lifespan of your battery. Calibration may or may not be a placebo, however, it really depends on how you use and what type of battery you use. If it has no effect for you on the first "calibration", please do not continue to drain your battery everyday.

This module is abandoned, however, if you would like to help in the development, you may do so and I will update the module if needed
Awesome gift bud. Happy holidays
Exactly what I've been looking for
Happy holidays!

some questions from me:
1. if phone's battery goes '0' bar, will it shutdown automatically?
2. compatible with android 4.4.2 or not?
thanks in advance

1) No. Until your battery is completely dead
2) Yes, I haven't tested but it is compatible.
If it works, your phone will abruptly shutdown after receiving the "Blocked Shutdown X times"
If it doesn't work, you will see the shutdown dialog with the spinning wheel before your phone shuts down.

this might give an extra 5minutes juice, that's it?

Thanks for your explanation. So, Whats the side effect from this app to the battery life? not damage to the phone's battery, isn't?

Yea. Maybe more or less but long term usage will decrease your battery life. Only use it for calibration.

The side effect is allowing the battery to drain completely. Ususally used for calibration but if you use it everyday over a long period of time, it WILL decrease your battery life.

So, when did the right time to use it?
Tried it with SGS4 I9500 Android 4.3
Doesn't work.
It's not compatible with 4.3 mate?
@zst123 gonna try it on my galaxy y duos stock GB 2.3.6.will post results later.
EDIT: it worked! thank you so much!

Lithium-Ion batteries are NOT meant to be drained. You WILL decrease the life of your battery (since it weakens the anode bars physically). Draining works for Ni-Mh batteries. Android calibrates your battery between 80 and 90% so if you have Lithium ion batteries, calibration is a placebo. Correct me if I'm wrong. :good:

Actually, if the battery metering chip (also known as the 'fuel gauge') is giving inaccurate results, calibration will make a world of difference. Here's an example - on my (generic Chinese) tablet, the meter often goes down quite slowly during usage, while voltage goes down normally (according to BMW). When the meter hits ~35%, the battery starts going down abruptly (~1%/second), until it gets to 0 and the tablet shuts down.
This doesn't mean at all that I have a flawed battery, since I am getting the same usage time as when I bought it (battery was flawed from the start? :silly: ) - the battery meter chip is simply inaccurate.
Thank you, OP, for this mod, it's gonna come in handy.
Sorry for my ignorance but what is the difference between this & removing the batterystats.bin system file?

Removing battery stats is different. On a battery with a terrible calibration, it will not prevent Android from shutting down when it (wrongly) detects a low battery. This module disables the shutdown when you reach 1% and below. Long term usage of draining to 0% WILL lower your battery life. So use only for calibration

Thanks. I recently purchased an extended battery with twice the mAh as the stock battery but I am still getting roughly the same amount of time out of a full charge. I am hoping this will fix that. :good:
YES!!!
Looking for 1 of this for sometime...
Good job...
My phone seems to have wonky battery life, it will jump from 14 to 12 to 10 to 3 percent then shut down.
This should help immensely for calibration if it does work.
Will report back. Happy holidays ☺

Didn't seem to work for my Beanstalk 4.4.2 HTC One. I am 100% willing to beta test or provide any data if needed
(I installed and activated module, rebooted, let battery drain to 0 from 16, phone proceeded to shut off right away)
