When I first got my x7501 it came equipped with WM6. When I was tinkering with it, the battery life bar gave me the exact percentage like 87% for example. After a hard reset, the battery life bar only gives me the percentage in increments of 10. It will say 90% for the longest time, then it'll all of a sudden drop to 80%. I'm wondering if I did anything by accident to make it function in increments of 10 instead of 1.

Mine has always been in increment of 10%. I don't recall ever seen it in exact percentage before.
same for me i only get it in 10% to
hmmm... maybe it was all in my mind.
Another vote for increments of 10 here. It would be nice if it was single digits, though...
same here increments of 10, any fix yet? should we buy a new battery?
its like that default,you can even keep an eye on the factory battery meter...theres no fix yet
The real problem is that the % remaining is only a rought SW evaluation of the battery power remaining.
10% step I think is the MAXIMUM to have something reliable IMHO...
1% steps? Unreliable I believe...

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
http://bit.ly/Ah732P

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've now had the I717 Note for a month or so, and coming off the Streak, it has been hard to wean myself off the "charge at every available chance" behavior that the Streak has taught me. After the first week of fully cycling the battery (100 percent to shut off a few times to "teach" the phone) I reverted back to my old Streak ways of plugging it in every chance I've gotten.
However, the last few days I've been avoiding charging at every turn, and just letting it ride. And, I've noticed something odd in the reported battery percentage. I'm on the stock ROM, rooted, with a big letter status bar widget that numerically reports battery percentage, as well as running Batt Stat on all home screens. And, in the last couple days, when I leave the phone for a while and don't use it, both battery status devices (and indeed, as it turns out, the built-in stock device) I see more percentage remaining after a few hours of non use than was reported when I put the thing down.
The first few days I figured I was nuts. But I started writing it down to make sure. And, yesterday and today in the 3 times I put it down, didn't get a call, and didn't play with it, I noticed the following: Call ended, percentage remaining: 75 percent. Two hours later (ish) check email, 76 percent. Call received, 65 percent. Hour and a half later: 67 percent. And, just now, call made: 27 percent. Hour later, after not being able to sleep: 28 percent.
Anyone else notice weird increase of reported battery percentage with what I'd call extended periods of non-use?
Bonus question... anyone got a theory about what's happening here? I mean, I did like 5 full charge/full dead cycles... the ROM should know by now (I'd think) what the battery charge state is.
Happens on a lot of phones.. the battery usage graph and % remaining at the top indicate an estimate of what your percentage is/should be based on your current usage. As you stated you noticed this increase after not using the phone, it is adjusting itself because you went from a period of use to a period of non-use.

Interesting. Never noticed it on my Streak.
But then, that thing would die in minutes it sometimes seemed... lol.
6 months with sk17i...
6 months with pain in (_!_) about battery indicator...
let me describe situation for those who have no such problem:
battery indicator lives with its own life after 30%... mainly in good days it drops from 20% to 1% but in general picture is not so smooth... I have some days when 45% becomes 1% and so on...
Trying to figure out source of the problem I've started to wipe battery status (any calibration software with root or CWM recovery option), but no luck... (yes, I should mentioned that I've also produce full reset of battery status with 100% charge in offline, then removing for 5-10 mins and charge rest of %) and that is definitly - not working... After full discharge without reboot or power off it is not 100% possibility that next discharge goes smooth from 100% to 1% it could breaks again on 15% or 20% or even on 40%.
I was thinking that problem in battery itself and also change it with new one but picture still the same.
According voltage values regular battery with ~1200 for "mini pro" should show from 4.1 to 3.5 values and it does! but battery indicator shows something else...
So question to community: do we have epic persone who can solve that problem?
P.S. as you can see bootloader is unlocked so no worranty availiable... only hope for community.
Batterystats file does not include battery information, it's about the battery usage info and that file is created again every time, that you fully charge battery.
My friend had this strange situation like your's, He had neo.
He visited service center & solved the problem.
I recommed you take it to the service center.
hi guys , i got some problem with the information displayed for my razr maxx. the thing is the battery usage curve won't change for the first 10% of power drain, and the awake bar and screen on bar are full. but when the battery drops to 80% and below, the curve starts to count from the 80% position, what is going on? how can i fix it ?
here is the screenshot
How many times have you already charged that battery from 0% to 100% and drained it back again to 0%?
Seems like a simple calibration issue that should have no effect in real world battery performance.
Had that too. If you want to know more about this, look up "batterystats.bin".
So, if you haven't done what I said in the first line, do it and report back.
i have tried delete the .bin file bwfore, nothing changed. i think i will try to charge it from 0to 100again see if there will be any change. btw will the battery calibration apps solve this?
http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/
Read that. You don't have to do anything, just let your razr get some charge cycles and the readouts will be right. Remember: There is no need to tinker with this, as this has no effect except for cosmetic terms.
thanks for the information. one more thing, the battery indicator always shows that the screen on and awake time are the same, even after i turn off the screen and play music for an hour. is this normal? or the system keeps recognizing the status of the screen as on? how should i deal with this?
I would just wait a few days (read: charge cycles) and look again. Indeed strange, but if your battery doesn't get drained this also seems just to be another cosmetic issue.
actually it seems it has been more energy draining than before. it wouldn't drop 1% when i turned on flight mode at night and checked it in the morning. but now even i turn on flight mode it drops about 5% next morning.

Don't count on the battery percentage today. Look again tomorrow/after some charge cycles.
The battery readouts need to be calibrated to display the correct battery level.
I had the same "issues" (in fact, those don't seem to be real issues) and they went away. I assume your razr will behave the same as mine
Is the phone still new? I know mine was a little wonky until the charging and the meter apparently calibrated themselves to Maxx's battery Ever since, it's been very accurate.
yes it is still new. i got it about half a month ago. just got it charged to 100% from 0%. gonna see what will happen。
I accidentally found a way to over come the unsual battery drain. This method may not work out with completely worn out - old batteries. A month after I bought my s3, my battery started to drain excessively. I had installed no new apps..
Phone Usage was almost the same. Before the battery drain I got almost 26~30 hours of battery at normal use... after the battery drain I got less than 12 hours for the same usage.
So here is the method.
Put the phone on charge. After puttting it on charge, switch off the phone... u can restart it after twenty seconds... ideally wait till the phone cools down, if it feels hot... don't use the phone till it reaches 100% charge. This method works for any initial charge. I.e. it works when the battery is at 98% or at 1%. But if u try this method when u have 1% and u keep using the phone while charging, this method may not work... so ideally don't use the phone while charging.
So now I do this everyday and my phone lasts for 26~30 hours on normal use.
I used gsam battery monitor pro to monitor my phone's temperature and battery usage.
It also gives the average number of hours the battery will last.
For those who dont know : Ideally charge the battery when it is leas than 10%. This will increase the overall battery life.
P.s. it works for me. Don't complain if it doesn't work for u!!

You basically calibrated your battery. Typically only needs done about once a month at most to keep your battery gauge accurate. Any more than that hurts your battery.

Calibration is draining the battery till 0%, phone switches off and charging it till 100% when the phone is switched off.
This did not do the job. Battery drain was still bad.
After trying out my method, i charged the phone for two or three cycles without this method. Then the battery drain got horrible till the method was repeated.
I have been testing this method for a month. It hasn't caused Any harm. My battery life is good.
Its in effect the well posted bump charge method .

I don't know a lot about batteries so I don't know how much of this is true.
I read that the phones chip, if it regularly see's the phone's battery going no lower than say, 15% over time (i.e, user always charges it once it hits 15%) that it will start to use this 15% mark as the "empty" level and that the best thing to do is to "remind it" every now and again, that there are battery levels below this 15% by letting it drain to 0%
Anyone got any comments on that?

Once you get above 90%, I would stop worrying about it. I think most if not all devices need to go through charge/discharge cycles while fully charged to keep the battery life good, so when it is "charged" it will actually be ramping up and down to do that. How this is shown to the user varies across manufacturers, and there is really no clearly right solution -- if you show them the actual changes in level they start complaining and getting concerned about their battery not being at 100%, so it is good to just show it at 100% at this point but then you are giving a little white lie about the actual level.
NOTE last line 100% is not really true .
As to the 15% all i read is that continual dropping below 15% / 10% is bad for the battery's overall life .

The other thing with Li-On batteries is that (as you say) using the last 10-15% of charge is damaging to overall battery life. If the battery reaches "True 0", it would be irreparable. That said, this last 10-15% of "Danger zone" (as I will now call it) is inhibited by an EPROM setting so a user cannot actually get below that.
Essentially, what I am saying is that the 10-15% "danger zone" is not included in the 0-100% that we perceive to be the "battery life" as the user.
So in the 1st attached image, the Red area represents the "danger Zone" or EEPROM protected charge. The Green area represents the 0-100% that we use as a user.
But in this case, I am asking if the EPROM sees the 15% remaining charge of the green area (forgetting the danger zone exists), if regularly not dropping below that, it becomes the new 0%, losing the last 15% of the green area as per the second image?
The phone only sees a reported voltage value, which it compares to a table giving an approximate % remaining - based on a fixed battery capacity.
The 15% danger/red zone you refer to is below the minimum voltage the phone will allow the battery to ever reach, as below this value the battery itself will act to disconnect - giving unexpected shut down and data loss/partition corruption. You would also be unable to recover a battery in this condition with a normal charger.
Best advise is still to recharge before the battery reaches 10 to 15% of the phone's indicated remaining value - you can safely go down to 0% indicated but will lose a little battery capacity each time you do this, as the electrodes inside the cell are being worn away. It's no big deal, hence why the phone permits it to happen, you'll just need to replace the battery earlier.
Similarly charging to 100% and holding the cell there is just as bad, remove from the charger and start using it right away.

*shrug* Sorry, I read your post about 10 times last night and figured you were talking about calibration. I then posted accordingly. Tonight, after I read your reply, I tried reading your post again a few more times. Finally, I came to the conclusion that your post makes no sense, so I give up trying to decipher what your post was trying to say. I surrender.
The best answer to the battery drain issue is a application called "GREENIFY". It closes all the background applications.. Try it n thank me if u feel it worked.. It increased my battery life more than twice..
