Has anyone else experienced any problems with their battery stats resetting themselves? Mine used to be accurate (at least in terms of running time since unplugged) -- but ever since I flashed to 1.5.7 (and got tremendously better battery life) -- when I check later on in the day I notice the stats seem to have reset at some point in the day.
This morning I unplugged at 8am exactly, and now checked at 7pm and my battery stats claimed 8hrs unplugged ....
Anyone else have this problem?
i am thinking that my battery life has gone down since applying the update, so i deleted the batterystats file last night and charged it over night.
i did not notice that the stats you mentioned were an issue on my phone, though. one of the few things i have been looking at is the uptime, and it seems to be accurate.
does anyone know for sure if the batterystats.bin file should be deleted just before the battery dies, or after a full charge on this phone?
I'm not sure if it's the same with the Atrix, but on my Samsung Galaxy-S we used to delete batterystats.bin right after full charge, then it would create a new one automatically and begin tracking.
where is it located on the Atrix?
Thanks!
i used root explorer to find it under data/system/batterystats
after you deleted the stats from a full charge would you drain the battery until it turned off or charge it whenever you felt like it?

Personally I would drain it until the end --- you're trying to gauge a full battery's worth right? Charging it mid-way wouldn't tell you much
thats what i thought too, but i havent done that in many months (since i had my nexus 1 and was flash happy). i did a search in this forum last night and the only thing i found suggested wipping the stats when the phone was almost dead, then charging with the phone off until full. in my head i thought delete the stats from full and then let it die, so i was unsure as to which way was right
Ok so I just tested and realized the battery stats RESET after a REBOOT ... doh~
Is that normal for everyone else?

Hi all!
I recently flashed Trigger + Overstock. The problem is related to battery drain. I am trying to re-condition the battery/wipe battery stats...However, My battery will not charge to 100%. It stays at 99%. I assume this isn't normal. Wondering if anyone else has come across this before?
Any ideas? Or can someone point me in the correct direction to fixing this?
Thanks!
My devices usually stay at 97% no matter how long I charge it.. Sidekick 2008, iPod Touch, Vibrant, even my computer.
I'm not sure why.
Yeah...it's just weird. I mean it used to charge all the way up to 100% and even notify me that it was completely charged before I flashed it.
By no means am I complaining about it. I just was wondering if that was normal after a flash. Also, more importantly will re-conditioning of the battery still have the same effect even though it's not at 100%? That's my real concern to get good battery life without going back to stock.
Thanks!
I had the same issue for awhile and honestly it seemed to more or less resolve itself after a few charges. I don't know if that was just my experience of the ROM updating the battery stats.
Have you fully charged the battery and wiped the battery stats? Even after doing so, it may take a few charges for the ROM to fully recognize the proper battery levels.

Yeah, I fully charged it...well to 99%. Then wiped battery stats. Hopefully like you said it will correct itself after a few charges.
In regards to wiping the battery stats, did you use root explorer and delete the batterystats.bin file in the system folder or did you try to wipe the via the CW Recovery menu? I personally never had much luck doing it through the menu.
I've bought a new legit/official (has holo, serials etc.) Atrix battery.
Charged it to 100%.
During usage, its draining literally 10% an hour with very light usage (several minutes an hour). In short its draining at three times the speed of my 1 year old battery.
I've tried wiping battery stats but that didn't work.
Any ideas, or is the stats just buggered and I just gotta run it in? (ie it will go to zero then sit on zero for 5-6 hours lol)
note I've gone back to my original battery in meantime rofl
EDIT: The actual problem is that the batt is reporting much less capacity than it actually has
|The new battery is great capacity wise lasts till midnight
However the stats are still totally screwed, it will say 1% by midday, then hum along until midnight fixed at 1% (I dunno exactly how long for as I can't take the risk of leaving it off at night then its dead and I don't wake up for work in morning). |
Could just be a bad battery. Considering the old works fine that's probably the problem.

I have a similar problem with the original battery that came with phone it drains the charge quickly to 1% and on one 1% it gives a battery life of more time than the time it took to discharge from 100%.i was thinking of buying a new battery but now i am confused that what should i look before buying the battery to get a battery that can show me the exact charge on the indicator.
I have tried all tutorial of calibration used different roms and kernels but nothing seems to solve the issue.
well I might try that then, just let it run to zero see how long it lasts then see whether the stats come good over time
OK help needed.
The new battery is great capacity wise, lasts from morning to bedtime with >2 hours of bluetooth music, 30 mins calls, a ton of texts.
However the stats are still totally screwed, it will say 1% by midday, then hum along until midnight fixed at 1% (I dunno exactly how long for as I can't take the risk of leaving it off at night then its dead and I don't wake up for work in morning).
Aside from wiping stats which I have tried, is there anythnig else I can do?
I really want to use it, like I said real life capacity is great, but if its always giong to be reporting 1% its a bit dicey not knowing how much batt you really have left...
same issue with my spare battery not sure wtf is going on
When I have battery stat problems the following has always fixed it:
1) leave phone on until it dies
2) take back off phone and plug into wall charger
3) after batt symbol shows 100% (without unplugging or turning off the phone) remove the battery. After a minute or so battery symbol will have question mark
4) put battery back in and leave it for at least 2 hours (seems like I have had to press the switch sometimes but you don't want the phone to reboot or you will have to start all over)
5) reboot into CWM and wipe the battery stats
6) reboot and it should be good to go
Anyone else found a fix to this yet?
I'm now running ICS (turl build) issue is still there.
Steps taken to resolve
- discharge to zero
- charge to max
- wipe stats
still there.
The weird thing is that the actual capacity is fine, it can last all day no worries, just from midday onwards it thinks its 1% so has annoying LED flashing at you, also you have no idea how much batt it actually has.
Edit: I just realised your suggestion above has extra step (take batt out of connected atrix then insert again). I guess I'll have to drain it again and do it overnight... gah

Nothing will work i have tried almost every tutorial. Recently i found out the phone is showing the the full capacity of battery only 500 that's why i think we will have to change that with the actual voltage to get a accurate battery indicator.What's ur battery full charge design check if from the root exploler
/sys/devices/platform/cpap_battery/power_supply/battery
My phone uevent is showing this
Powersupply-capacity=5
Powersupply-voltage-now=3836000
Powersupply-temp=260
Powersupply-charge-fill-design=500
Powersupply-charge-counter=1

I'll try the insert empty bat into already connected phone, charge to 100% remaining off, repeat trick overnight, then report back.
FWIW on my 'good' battery which is 1 year old ROFL it says 1880
not sure how changing it would help though or is even possible?. It must be dynamically reported somehow as my good battery gives me a 'good' stat.
I use battery calibration and it worked, have it

the battery is charging calibration if you have to load it to calibrate

How much is ur other battery showing.I have tried different ways but was not able to change values.
500 same as you! second drain and calibrate did nothing
Maybe theres a faulty batch of batteries and we both got one
Can people PLEASE stop telling us to calibrate we've BOTH DONE THAT MANY TIMES NOW. The problem is that the capacity of the battery is being reported as 500mah not 1930 or whatever its supposed to be. THe actual running time of the battery is fantastic, just thinks its at 0 all the time lol
/sys/devices/platform/cpap_battery/power_supply/battery
Powersupply-charge-fill-design=500 - should be ~1900mah

I tried searching this in a number of places. I couldn't find what I was looking for, although it didn't help I had trouble using the right words to search for it with, but here goes.
I'm running CleanROM Reborn 1.1, I love it! Other info is also in my signature. Once I turned on the percentage number for my battery level, I really started to notice this.
The number will stay at a number for awhile sometimes, even when I use it, then other times it will jump several points within a minute. It doesn't drain consistently. Anyone have any insight or suggestions? It's more annoying than anything else. My battery life is alright.
I would've tried wiping battery stats, but I hear that doesn't really do anything.
Thanks.
download Battery Calibration from the Google Play Store, then charge your phone to %100. open the Battery Calibration app and calibrate it. There is also instructions inside the App if my instructions are unclear
Im going to try this but for some reason mine only go to about 96%. Never 100% lately so I am not sure if I should do it then or just leave it charged until it is 100% and hope it gets there.

Not to hijack the thread, but the phone is designed to fully charge and then discharge to 95% and then charge to 100% again, rinse, and repeat. This is to keep the battery from becoming destroyed by overcharging. Maybe that's what you are seeing, Bambino.

I've noticed this too on Ics leak roms. It sips power with screen off, then drains quickly when on sometimes and hardly at all other times. Mine just sat at 82% for the past 20 minutes, then dropped to 76% over the past five. I've heard battery calibration is bunk, but I'll try the previously mentioned app and see.
Some roms do not use a percentage because they are so inaccurate and cause the user to obsess

A little info on batteries
The important thing to remember about Lithium Ion batteries is that when you do charge them, bring them up to full charge before taking them off the charger.
They all have a circuit board in them that remembers a full charge. (If you've every taken one apart you'd see this) When you charge them this chip will restore the amount of power that has drained.
Partially charging them will screw up this function. And screw up the battery.
Deep Cycling is good for them but not all the time. Once a month is good for them.
A good rule of thumb, but not absolutely necessary is to discharge them 50% and then bring them up to a full charge. Obviously this is not always possible when playing video games or watching movies. I always try to leave it on the charger when watching movies in the cradle.
There is an app on the Market called Battery Repair. It makes an attempt to reset this chip on the battery by meticulous monitoring the charge and capacity left in the battery. Running diagnostics and setting the battery to its best state. Its the only one out there that does this.
Battery Calibration app is good if you change roms or batteries alot.
Here is what it does:
Calibration needs to be done after flashing a new ROM, but you can calibrate any time you think your battery is miscalibrated. This program does it by removing the batterystats.bin system file. The OS generates a new clean batterystats file soon, thus any fake information from the previous ROM is removed.
It's suggested, but not necessary, to let the phone fully discharge after calibration, then charged to 100% without break.
The app shows your actual battery status, and only allows you to start the calibration (i.e. removes the file) when it's fully charged, unless you force earlier calibration.
The voltage meter can be useful too. Full charge is around 4200mV.
I recently had my Thunderbolt replaced with a refurb from Verizon. When I got the new phone I removed my old battery, which was working fine, from my old phone and placed it in my new phone. Now in the new phone I fully charge the battery and I get about 45 minutes to an hour of battery life before my phone is down to 2% battery life. However, the phone then has the same battery life as it did in my old phone, it just still says there is only 2% battery life left.
I'd tried completely killing the battery then recharging fully for about a week. The battery stats never reset.
I then rooted my phone, charged it completely and purged the battery stats. The issue persists.
Sounds like an aftermarket, non-oem battery...is it?
If it isn't a stock oem battery and especially if running ICS, it will not read correctly.
It may charge and discharge properly, but may never read accurately.
If it is an oem battery, then you got me.
Well i did this thing on my cousin's Htc Amaze a long time ago
i used die hard battrey calibirator to calibrate the battery. the phone was showing 2 percent supposed to be 170 percent so i pressed calibrate button and it worked for about a week until the battery had the same error
try doing that it might do something... or nothing at all but worth a try

Nope, it's the original battery I received with the phone. I'd understand if it were just time for a replacement but the fact that it stays awake at 2% for so long leads me to believe it's not actually an issue with the battery.
If you calibrate the battery incorrectly it can make the phone display the wrong amount. I did this before using die hard battery calibrator. To manually recalibrate. Discharge the phone totally and then charge it until the green light comes on. Boot into recovery and then wipe battery stats in recovery. That might help you out but I somehow doubt itm

I tried using a battery calibration app and haven't seen any change.
I also looked for my batterystats.bin file in /data/system to manually delete using a file explorer but I didn't see it there. Does anyone know why that may be or if that could contribute to the issue?

Disregard that, turns out I didn't have ES File Explorer with root permission.
Li-on batteries don't actually perform the way many people think they do. They do not discharge in a linear fashion. That's what makes metering them on the phone so complicated. As the battery ages it's non-linear output changes as well, and that's what the statistics are designed to correct for when displaying a charge level.
Here's how you know your battery is a dud.
Pay attention to the voltage. As a Li-on battery discharges it discharges in a very flat way. The battery is fully charged when the voltage curve of the battery begins to ramp up sharply. The battery is technically dead when the voltage begins to drop off sharply. What ultimately renders a Li-on battery garbage is when that fat flat spot in it's voltage/charge curve drops below a threshold that will power the device. If the battery is displaying adequate voltage for a reasonable length of time and the phone still reads inaccurate, then it's the fault of the phone.
I have an att galaxy s3 (d2att) that I got back in March 2013. Over the course of the year I have probably changed my rom about 20-30 times to get the perfect rom. Now my phone's screen time is about 1 hour while just letting it sit with the display on and not running any apps or touching it. Currently running the task650 rom with android 4.4.3. Wiping the battery stats file or running the calibration app does not work. There is no option in my recovery menu under advanced settings to wipe battery stats and a battery calibration app says the battery file does not exist. Sometimes the phone will turn off at about 30% and the reason I believe for that is that the voltage goes down so much. On time I checked it around 35-40% and it was at about 2.5V and then it shut down. When I charge it, it hovers around 3.9-4.3V but when I use it, it starts to go down like crazy. I don't know if I need a new battery or if I should completely factory reset my phone.
Any advice?

A bad battery can be really dangerous. It may have become like this because of bad use or overuse. I would recommend changing it asap

I don't see how flashing many ROMs could cause your battery life to drop. However the following issues are possible:
1) The ROM you are using has a bug that is causing some type of battery drain. These do happen.
2) You have charged and discharged your battery so many times that it cannot hold a charge anymore. I start noticing battery life decreasing after about 2 years of my usage (generally fairly low). Most times my battery life does not drop below 60% or so. If you very often let it drop very low, I can see the battery life decrease significantly after about a year.

Yea, I can only assume that because I have let it drop so low many times, I might have ruined the cells within. I might just end up buying a new battery. Thanks.
