[help]Motorola xt 912 battery problem - General Questions and Answers

I have motorola xt912 it has same dimensions and shape everything like the one Motorola cell which have battery of 3300 mah(EB40) I have xheck my cell has same 3300 mAh battery ( i checked myself) . But my cell shows a battery capacity of 1780 mAh. I aslo calibrated my battery but still same problem. I have jb latest update installed. Due to this problem my cell is giving a very poor backup. Please help me out.

Whatever app you're using is only reading the firmware of your phone and comparing it to a database, and not reading the actual battery capacity. The Droid RAZR (not MAXX) has a 1780mAh battery. There is both a RAZR and RAZR MAXX with the XT912 model number. Your phone doesn't actually "know" how much battery life you have left. It knows the voltage and amperage draws and makes an estimate based on typical data for that battery's chemistry (lithium ion, lithium polymer, whatever). Any app or built-in feature that tells you how much life you have left or how much time to reach full charge just uses algorithms based on that data. That's why you often drop a bunch of percent for no reason, especially if the phone is well used - it's just a guess.

[Q] Users of Battery Monitor Widget (BMW): What is your reported battery capacity?

Hi there,
I am hoping that there are some "Battery Monitor Widget" (BMW) users with us, and that you would share your values which BMW is detecting.
As far as I understand and can tell the Transformer does not report measured mAh values and BMW does some estimations and calculations by monitoring over a long time.
After a month or so my TF101G showed an estimated capacity of 23614 mAh ... you get it that I am confused. Therefor I am asking you to post your values, eg. with a screenshot of the "Calibration" page of BWM.
As far as I can tell, nobody has posted these values, at least not @XDA. So this would really be interesting, maybe also for 3c (author of BMW).
Greetings,
- Stephen

Really no one willing to share their battery's capacity as reported by Batter Monitor Widget (BMW)?

Hey man, I'm not much of a pro of this widget, i downloaded it yesterday but may I ask, in your Settings-Monitoring-Battery Capacity(mah), what is written there exactly?
Installed it on my Motorola Defy and it work superbly... But in my TF101, it doesn't seemed to show the details I expected.
The battery capacity, what do you enter here? Is the BMW detect the dock battery?
I'd run it over two days but the data shows doesn't seemed to be right, so uninstalled it..
If you have any proper steps or ways to make it work in TF101.. please write here.
Sent from my Transformer TF101 using XDA Premium HD app
In battery capacity option, you write your battery mah as you know it. I got extended 3500 mah so I wrote 3500 there, measured the mah with the app using the app for a day, it said 4580 mah. Well, there is no way that is right
I'm gonna use the app for some day, see if the measured mah is gonna change.
The app can not read the externals battery, it seems to be totally unaware. It also seems to register any power from the keyboard dock's battery as an external charger.
As the TF101 does not report measured mAh values as other devices do (e.g. my HTC Desire Bravo A8181) it uses estimates from the OS system logs (as far as I understand).
The app's author suggests - at best - a maximum complete discharge/charge cycle for guessing accurate values (maybe it's the other way around: first fully charge, then discharge; or it doesn't matter; but: do no discharge your Li-Ion battery completely as this is known to harm Li-Ion's (e.g. batteryuniversity, dont know their reliability), try at least a charge cycle of 50%)
It took quite some time until my mAh value stabilized at the value of 23614mAh that I got. For about 2 weeks the value was rising and stopped then at 23614mAh.
Yes, as I remember the mAh-value you are asked for at e.g. the first use is an estimation/hypothetical temporary value used for calculations and which will be corrected with the measured/estimated values over time.
The app and it terms are in some cases confusing/unclear without reading the docs which can be found here and are quite enlighting. In general I use this app a lot on my Desire where it measured the battery's capacity with 14xx mAh which is a little more than the expected capacity claimed by HTC (and I treated my battery quite well).
About the capacity of an Asus TF101(G): I left my tablet running under these cirumstances (the first time accidentially, the second time planned):
flight mode on (no 3g, wifi, bluetooth, me telling you just because you can enable the latter two even in flightmode!)
screen set to lowest value
no apps except battery monitor run on purpose (background tasks left untouched)
OS 3.2.1 stock ROM completely untouched (only the OTA which gave me this OS version)
The results of this test:
from 100% battery to 8% battery within 8 hours 20 min
the battery usage screen of Android control panel showed following "distribution" of power:
Screen: 86%
Android OS: 11%
Android System: 3%
no other entries!
My (quick) conclusion of this test is: as Asus promotes this device with about 8 hours of HD video playback (which I expect to be a processor sucking task) on one charge, without keyboard dock, and as other sites with this' tablet reviews report the same, my device underperforms "highly".
(Sorry, I did not start reading the - for sure - existing threads about battery life in this forum, as I "hoped" that a simple comparison of "Battery monitor widget" values would enlighten me. But, for sure I have to dive into these discussions.)

Droid Maxx Battery capacity decreased fast ?

my droid maxx had in the beginning of july a battery capacity of 3488 mah. now the current capacity is 3130mah. i already tried to recalibrate the battery with recharging it from 0 (when the phone turns off because it has no power) but that didnt helped. i am using battery monitor to look at the capacity. as i live in germany, i am using an samsung plug for charging. the original plug from the droid maxx delivers 5v and 1150ma. my charger delivers 5v and 1000ma, so it shouldnt make that problem.
is my battery still ok or have you any ideas ?

That's not true. It's better for the battery to be kept between about 40 and 80 percent and the battery will last longer with a lot of small charges rather than a small number of big charges. Depleting the battery regularly is not good for it.
See http://arstechnica.com/gadgets/2014/04/ask-ars-the-best-way-to-use-a-lithium-ion-battery-redux/ and http://mashable.com/2014/06/18/phone-charging-myths/
You can also read some more technical info at http://batteryuniversity.com/
Oy. Big debate.. To each their own I guess.
My battery lasts just as long as day 1. I use the 2.1a micro usb led AC charger sold at Verizon made by fonas. I top off from 30 to 90-95. Yes it's protected from over charging. But letting your battery drop below 20 is not good.
I do a full cycle once a month from 15 to 100%
Is your phone under warranty? There aren't any 32gb droid maxx models currently listed on swappa.com they tend to sell more than the 16gbs new.
there can i look how much warranty i have ?
i still have warranty for my droid maxx until november 2014. but i am living in germany and using it here. the phone has no bad esn or something like that. could i still get help ? even if it is the battery ?
also i have unlocked my bootloader with the chinese guy...

Ehh.... You may or may not have any luck sending in to Motorola. They may say your warranty is voided. Then again they may replace your battery.
I don't know how reliant you are on the root or unlock. Because there is an exploit under works to do just that.
I'd say just keep it and use it until something better comes out and sell it then.
Or sell it and try finding a replacement that's on older firmware or just get it and wait for the new exploit.
I would like to think there are probably many people over seas who would love to buy your phone. Just be honest when you sell it and say what the reported capacity is.
In the mean time, for better battery life,
Install one power guard not pro in play store. Choose ai mode.
Also install greenify and donate version, enable in xposed, greenify every app and a few system apps.

Phone Showing wrong Information On Battery capacity (3000mah as 2000mah)

My device is Micromax Canvas 2 Colors (A120)....The original battery capacity was 2000mah.....Recently i replaced my swollen 2000mah battery with a 3000mah battery.....The battery is for the device Micromax A116 (Screenshot is attached).....The battery fits perfectly and has the same rating as of the original.......When i started using my phone the standby hours or talk time hours are not increased (i think the percentage drop is faster than the stock,now the percentage drop is 1% per 2or 3 min).....Then i checked my battery capacity using an app called phone tester ( screen shot is attached)...I have tried calibrating the battery but it didn't helped....Tried this in stock ROM and other custom Roms......

Well, you are presuming that aftermarket battery, which is neither more massive nor bigger than the original, is actually a 3000mAh unit? Huh!
eBay is also full of 6000mAh labeled cheap “Ultrafake” 18650 li-ions, when actual brand name top-notch stuff barely does 3500mAh under best conditions…
It really does not matter what the battery ID chip is telling the system, or what the system believes about the battery capacity, as that is just a number stored on a register/memory cell block somewhere.
Use the device normally to see if you are getting the supposed extra battery life or not (mmm not wanting to dishearten you but, to me, that sounds like a knock-off). :silly:

Mi4c Real Capacity of the Battery

Hi to all,
I just wanted to make a debate about the real capacity of our phones batteries.
That's because I found an app that allows us to measure the real capacity and I found a quite astonishing result: it seems like my battery has the same behaviour as a 2200mAh ones!
In fact, with all connection active (Bluetooth, Wifi, LTE, synchronization..) I barely reach 3h of SOT daily.
I used 3C toolbox (https://play.google.com/store/apps/details?id=ccc71.at.free) using the instructions in this answer (https://android.stackexchange.com/q...ity-of-a-battery-in-mah-received-fake-battery in "How to measure actual capacity using 3C Toolbox").
Also if you can advise different apps and methods to do this, I would be very happy.
Thanks to all!
The real battery capacity is the advertised one. 3000-3080mAh.
Xiaomi uses lower binned batteries which degrade a bit faster over time. An app can't measure the real battery capacity or estimate it accurately. The SOC we have is power hungry and inefficient, that's why it's so hot too.
I think it's 1500 mah or something like that. I get only 2 or 2.5 hours screen on time. The results has been never changed which i've tried several roms.

Well, the app don't measure the battery capacity, but how much current flows in when it's charging.
So you're saying that the main problem is the age of the battery..
Do you think that changing battery may improve the result?
3h sot is normal, when used from morning till evening. When used continually, I get 5-6h sot. An app cannot accurately measure battery capacity. This phone, like many others, is built to last a day with moderate usage...

Hello, this is a very interesting topic, so I decided to check the real capacity of my Mi4c's battery with one of these. When the phone turned off at 0% I recharged it to 100%, while still off, with the following result: 1.76Ah @ 8.8V as I was using a QC2 charger. Let's translate it to the battery's 3.8V assuming 80% charging circuit conversion efficiency:
Code:
((8.8 * 1.76) / 3.8) * 0.8 = 3.2Ah
My battery is 6 months old and seems to be slightly better than specified.
If you use a 5V non-QC charger try one of these to measure it and assume higher 90% efficiency. Android battery apps are useless, please check it out with a hardware meter...
:highfive:
I'm already running third battery with my mi4c, all three tested with a similar hardware meter:
1. original battery, but already with signs of being worn out (shutdowns, sudden voltage drops) ~12Wh, not tested as being new
2. aliexpress replacement (getting worn out after 3months of use) ~13Wh
3. some battery I've got at local online shop that seller claims to be original (not 100% sure, but dimensions and weight match the original one) - sligthly over 14Wh
4. -another mi4c, as it was brand new- just over 14Wh from empty to max; surely the battery is in good condition as the one can reach 6h SoT
and I've tried different chargers (QC,non-QC) and no go - no way to see 15Wh or more being transmitted in one charge on both mi4c's I've got at home
Find out about battery behaviour of Nexus 5x, as its specs are very similar to mi4c's and compare battery capacity and standby/sot

And our battery behavior is a lot better.
Should I consider the values from /sys/class/power_supply/bms/ valid?
charge_full = 1983000
charge_full_design = 3071000
Does that mean that my battery capacity is now only ~2000 mAh?
EDIT:
charge_now_raw reports 2952776 when my battery level is 98%. So something is definitely wrong there.
Writing more stats for comparison:
cycle_count: 20430
resistance: 279541
esr_count: 63

voltage_ocv: 4323094

Your results are fine but you're not accounting for the efficiency of charging which also decreases with higher...
charger's voltage
meter's internal resistance
connecting cable and contacts resistance
My 15.7Wh on the meter is actually around 15.7*0.8=12.5Wh on the battery.

Some of them are definitively valid, others depend on type/firmware version of the control chip integrated in your battery. Here are mine:
Code:
POWER_SUPPLY_NAME=bms
POWER_SUPPLY_CAPACITY=51
POWER_SUPPLY_CAPACITY_RAW=5143
POWER_SUPPLY_CURRENT_NOW=432278
POWER_SUPPLY_VOLTAGE_NOW=3837410
POWER_SUPPLY_VOLTAGE_OCV=3874031
POWER_SUPPLY_VOLTAGE_MAX_DESIGN=4400000
POWER_SUPPLY_CHARGE_NOW=0
POWER_SUPPLY_CHARGE_NOW_RAW=1481002
POWER_SUPPLY_CHARGE_NOW_ERROR=98504
POWER_SUPPLY_CHARGE_FULL=3101000
POWER_SUPPLY_CHARGE_FULL_DESIGN=3071000
POWER_SUPPLY_TEMP=285
POWER_SUPPLY_TEMP_COOL=0
POWER_SUPPLY_TEMP_WARM=450
POWER_SUPPLY_RESISTANCE=110778
POWER_SUPPLY_RESISTANCE_ID=50306
POWER_SUPPLY_BATTERY_TYPE=x11_atl
POWER_SUPPLY_UPDATE_NOW=0
POWER_SUPPLY_ESR_COUNT=64
POWER_SUPPLY_VOLTAGE_MIN=1
POWER_SUPPLY_CYCLE_COUNT=0
It was measured with the power gauge at around 55%. My CYCLE_COUNT is surely higher than 0 after 6 months of use, and your CYCLE_COUNT=20430 is simply impossible
I'd more believe your charge_now_raw = 2952776 than charge_full = 1983000.
Incidentally, the simplest way to get these stats is from TWRP in ADB:
Code:
adb shell cat /sys/class/power_supply/bms/* > bms.txt
Hey guys, long time no see
I did not see the thread, but i went on with my speculations on the same matter.
I bought this from amazon https://www.amazon.it/gp/product/B00NPVZHAO/ because i wanted to test my day-one mi4c battery.
It has roughly one year and a half.
Well...from 0 to 100% it gets a whopping 1617 mAh (see the attachment).
I was disappointed, but hey, maybe i had a degraded battery to start with, and since i never measured before i went on to buy a new original one.
Well, yesterday it arrived. changed it, discharged to 0%, charged to 100%.
Okay, it's only the first cycle, but...
1800 mAh
I guess advertised capacity is a long way from the real one?
After all, if this is correct my old battery degraded by 10% in 18 months...and that's realistic.
Please tell me i'm wrong.
I bought it for this job and I wait. But unfortunately there is not much hope
Nexus 5x has very similar specs and very similar SOT. Also, the original qc charger is supposed to charge using 5v,9v and 12v, not only 5v. What does that say about your research? Either both manufacturers lie, or you're doing something wrong.
I get anywhere from typical 3h(usage from morning till night) to 6h(continuous movie watching using streaming). For the record...

Code:
((8.91 * 1.617) / 3.8) * 0.8 = 3.03Ah
Which is exactly as advertised by the manufacturer.
No need to change batteries, your SOT is low because of the awful apps you use. For example, did you know that "uninstalling Facebook app saves up to 20% of Android battery life"? You can still use FB and its notifications without the app - read the article.

Thanks @k23m, i felt like a student again but after reviewing your formula you are right.
I though the tool's mAh measurement were already adjusted for the battery's voltage, but as you showed we still need to do some math.
I guess that i didn't need a new battery after all, but now that i have one it's certainly better!
I don't have issues with SoT, i do 5-6h on TS CM13 (i stay on marshmallow for xposed) but i just wanted to test battery degradation.
I will still post new battery results after a few cycles.

Is OP6 battery really 3300...?

Hi, just wanted to ask if someone else beside me and my friend got a 3000mAh battery (According to accubattery) after a couple of months, the same happened to another friend of mine with a OnePlus 6T, 3450mAh instead of 3700mAh.
Screenshots attached.
Accubattery is insanely inaccurate, and takes an estimated guess based on charging cycles. Long story short, the app is garbage and people should stop putting faith in it.

I've already tried to search for a this app, and I found a thread in the OnePlus 5T section where a USB multimeter in, at least, two cases, has shown the same result as Accubattery.
Anyway thanks for the answer, need to find why battery sucks su much on both my friend phone and mine.
I experience the same issue !

I experience the exact same issue on my oneplus 6. The accubattery app shows my battery health as 3,046 mAh and design capacity as 3,300 mAh. It has been this way since the day I got the phone (around one month back). I am pretty bummed that oneplus sent me a phone that had only 90% battery life to start with. Is that a problem with the battery or is that a problem with the way the accubattery app reads the results?

Seriously? As stated before it is a calculated capacity. It measures how much goes in and out. While the battery is shipped as 3300 mAh the app can very well vary as it is only roughly calculated and the full capacity is very theoretical as the voltage decreases and is never zero.
You start with 4.35 V = 100 % and end at maybe 3.2 V = 0 %. So you have energy left after your phone as shut down. That's why you get a battery low screen even if your phone has shut itself down. It is not a design flaw and it is not scam.
Also don't forget that different components use different voltages. Transforming them results in wasted energy. Like a power bank that has 10000 mAh in theory only can charge maybe 7000 mAh while the rest is lost in heat.
thank you !

thank you for your detailed analysis !
It's kind of reassuring because when I bought mine it was second hand and I saw around 3000mah as well! So actually the battery wasn't damaged probably.
It could also be OnePlus which makes the choice to not allow the phone to charge completely so the battery lasts for longer in long term. I Kno Dell does it for example. Then it would be very acceptable. But yeah, maybe it's the app.
Had the same issue with several phones, for example with the S8+, Accubattery showed 97% from day one, after a few weeks it dropped a bit lower still.
The app seems highly inaccurate and I quit using it.
