Hi my friends,
I have a serious problem for some weeks now. When rebooting my phone, it shows another battery percentage (often it's 100%) when it was 60 or something else before rebooting. I thought first that it was software side but even with a fresh new install, it cames back.
Do you know how to reset battery stats or calibrate ?

I've been using my TP for few days & I noticed that the battery level is not working correctly. Some times the level won't drop even after heavy usage, after a soft reset it changes (maybe from 60% -> 20%), after another reset it changes to 40%. Sometimes I charge it overnight but the level is full, after a soft reset it changes to 60%. Is this a software bug or hareware problem?
Mine has just started doing this too, after a month of working fine. Ironically, at the same time, the battery life seems to have improved...
Someone suggested to me that this is a WinMob6 issue, and that it can improve with more charging cycles and soft-resets. Something to do with the battery meter calibrating itself.
This is kinda troublesome as I can't know the exact power left. My previous TyTN II had this problem but I found out it was caused by the battery itself, the problem was gone after I change to another battery. Is this the same case? Anyone solved this problem?
Unplugged from charger this morning and all was well, after about 12 hours I rebooted and now have stats that are acting like I just charged the phone (back to counting from 0.
Any idea what would cause this or how to fix it?
Should I delete the battery stats file and go through a full up charge cycle?
i dont really know what you are talking about but if the battery meter is acting like it is on a charger ie the icon show a battery filling up every couple seconds then it is likely a problem with the usb port. there may be some trash in there. could also be just some random bug and a power down and battery pull will reset the battery meter.
if you mean something else by "counting from zero" please explain. also this phone and samsung galaxy s phones have a standalone battery meter. it has some mapping that is preset but doesnt actually use "battstats" all those recal procedures that "helped" people in the galaxy s forums is plecebo effect. the battery life tends to appear to get better within a couple days after flashing a rom. throw a recal in the middle of those couple days and people naturally connect the better battery life with the recal.

What I mean is that lets say for example the battery stats show that the phone has been on battery for 1 day and when I reboot the counter is reset to 0 days (like if I had just pulled it off the charger). Twice now I have had the phone reset the time on battery counter along with the signal, awake, wifi graphs by only rebooting. this should not happen, i.e. the stats should not reset until charging is done. Hope that helps explain what I meant. Thanks.

What ROM are you on? From what I know, what you said happens on Froyo based ROMs. GB ROMs should not reset counter until phone is charged to 100%.
I have the exact same problem. On every reboot, battery use starts counting from 0 seconds. Anyone has a solution?

I had the same issue or should i say have. kinda. I'm on Zeus build 3 and when my batt gets to 100% i unplug...then maybe a cpl hours go by and i do a change and reboot..say three hours in. after reboot my "time on battery " resets to 0!!!!!!!!!!!!!! NOt supposed to.
What i did and do still cause NO ONE else knows they have the prob or don't have it. so i don't have a sure fix..
charge to 100. go into recovery and wipe battery stats. let it boot. wait a cpl minutes. reboot...usually it will reset but sonce it;s only been a cpl minutes who cares. then go aobut your business...after some time..hours... try rebooting. shoud stay.
Best i can offer until i guess someone else says they have same issue...
THEN going forward after i re charge to 100 i reboot right then. and it seems to be good from there.
Pain In The Ass. I asked other on Zeus to check but not sure they get it.

go into settings/about phone/Battery use.....That is what resets ..supposed to change of course when you upplug but try it...wait a few minutes..look at how much time on battery then reboot...it the "time on battery" starts over..you have the issue
I thought that was the normal behavior on Android, it resets the battery stats on every boot because while it was offline it might have been put in a charger and thus the battery stats might not be correct (or you could have changed batteries).
I for one don't see the problem with battery stats reseting on reboot, i reboot very rarely and when i do i usually do it to install firmwares or patches.
On the other hand now I've found an article by one of the Android developers and there it says :
This file (batterystats.bin found in data/system) is used to maintain, across reboots, low-level data about the kinds of operations the device and your apps are doing between battery changes. That is, it is solely used to compute the blame for battery usage shown in the "Battery Use" UI in settings.

So, it says "across reboots" so it shouldn't be reset by a reboot, that means that i thought wrong that the file is reset on each reboot
P.S. maybe the ROM that's on the phone does something that either deletes the file or forces a reset on the battery stats.
Try changing/setting permissions (through that option for permissions, can't recall the exact wordings) in CWM and see if that helps.
Hi all,
There's this problem with my phone that everytime I charge it, it takes an elongated time to do so. This issue first emerged when I was on stock GB after a minor OTA update which added the power saver toggle to the quick settings menu..The problem is that it takes about 4-5 hours to fully charge the phone, and if I rebooted in the middle of charging when it's about 70% or 80%, it suddenly shows that the phone is fully charged, and the indicator becomes green! But afterwards the battery drains as quickly!
Now I have S-Off and using ARHD 6.6.3 ROM, but it seems the problem persists ..I wiped battery stats as soon as I flashed the ROM as well..Although it's not a problem I cannot live with, it's annoying enough when it happens.
Can someone please help me? And suggest me what to do?

its common thing...the battery calibration is not proper that's all...
also you need to wipe stats once you charge your phone to 100%
then battery will try to calibrate ...and after 3-4 full complete cycles (100-0 and 0-100)
the battery will settle..
the battery drain will be there ...whenever you flash a rom or flash a kernel....battery only settles atleast after 2 full cycles
EDIT: also download currentwidget from market..as the name says its a widget..so you will see it in widgets once you installed it...this will give you more proper reading of battery...when you plug your phone to charge...and when current widget reads 0mah then your battery is charged completely...(it might take a long time to read 0mah...but charge it until you see 0mah)..then wipe the battery stats...so after this battery calibration will be proper
Also the sudden jump of battery percentage is due to improper battery calibration
so dont worry you got no problem
So
I read somewhere that you are not supposed to let the phone go to zero because it could cause your phone to not power back on anymore..is this fact. I couldn't find where I read it to back and read again. Mine has been doing some weird things as well...the led turns green before it is 100% and it goes from 100% and drops to like 89% out of no where.

when i meant 100%-0% means until your phone turns off due to less power..it might not(or won't be) be 0% then
as i told you that kind of jumps are common ...in my case it went to 60% to 100% when i rebooted ...also the dropping used to be in large scale too

Thanks mate! I will try this out! cheers!
Hello everyone,
I have a very unusual problem with my sensation xe. Let's say my battery is at 10%, i connect the charger, it say's charging, but my battery shows that is discharging and in fact , the battery is charging. The level goes 10%-9%....-0% than it jumps at 100% and goes again to 0%. I tried all the solutions here, but i found that nothing helps. I tried, Battery Calbration app from Play Store, I tried manually wipeing the battery status from recovery when full, i tried all the Rom's , new battery, stock ROM NOTHING! Even when i let the phone charge while in recovery, it doesn't show the true % of the battery.
The phone:
-S-OFF
-latest firmware/radio
-1.27 HBOOT
-now running MIUI
Please Help ME!
Still, the same problem :/
Those battery calibration apps dont do anything neither does the battery status wiping. The battery level indicator gets feedback from the sensor. So if you are having problems with the reading battery level, sensor is malfunctioning. If the battery holds i say ignore it. On the other hand if you have some cash put aside change the battery ( preferably get the same one, anchor batteries are of a larger capacity and are generally cooler but i've see people complain about your exact problem with them). No good news from me unfortunately but hope it clears the problem up for you... Cheers
Try to install app BetterBatteryStats, this could indicate the problem. I got the same problem as you and i delete battery data in recovery.
Hi guys, how you're doing? Hope you're fine.
I'm having some weird issues with my Maxx battery. My phone was showing 80% the last time I charged, when I rebooted it showed something around 74. The most weird part was when I rebooted to recovery right after, and TWRP showed 70%. All I could think by that time was that my battery is either dying or miscalibrated. I did all the battery calibration procedure but the problem persists.
Do you guys know any method to solve my problem?
Also, sorry for my bad English.
I'm not sure I understand the problem. What you're describing is normal behavior...rebooting places a high load on the CPU, which uses a considerable amount of power; you might have noticed that the phone gets pretty hot if booting up takes a long time. It's not uncommon or unreasonable to drop several % doing so.
If you're worried about miscalibration, run the phone until it shuts off, and then recharge it fully. But really, I wouldn't worry too much about it unless your phone starts doing very odd things (such as turning itself off anywhere above 5%).

My Turbo was shutting down at for low battery. Then I plug it in and it would show 20-22% on the power-off charging display. I tried the standard 'recalibration procedure' but it didn't work. I had success with the steps in this post. The app mentioned does a lot more than whatever the re-calibrate feature is, but I only used it for that.
