[SOLVED] Help needed after battery stats wipe - Desire Q&A, Help & Troubleshooting

After wiping battery stats, my phone only comes up with 0% of battery... is there any fix? :'(

Wiping battery stats is completely useless, despite what other people may say. The batterystats.bin file is created new every time you charge (if i remember correct). Try letting it sit for a while, plug off the charger, reboot, something like that. It should come back itself.

[Q] Need help with battery

hi all , i used my htc wildfire for 8 month and at first my battery displays 100% when its full but since 3 month till now it always display around ~ 40 - 60 % and can't increase more . So someone can help me . Thx for read and sorry for my bad english
Are you using custom ROM or the stock ROM that comes out of the box(Froyo v2.2) ?
If, you are on custom rom, then you may try deleting the batterystats.bin present in /data/system. But first charge your wildfire, and if your removing your wildy from the charger after it gets the green led indicator, then wait till it reaches the 100%. In my case my wildy gets the green indicator in 90% but I wait till it reaches the 100%.
So, when you get to 100 reboot into recovery and select the option "delete the batterystats.bin" in wipe section. and then use the phone till it reaches 20% and then connect to charger but this time make sure you do not use the phone till it reaches the 100%(you may charge it when its switched-off.).
Note: charging through USB connected to PC gives a better battery life than the adapter provided for charging.
If, you are not getting 100% as previously mentioned, then also you can try deleting the file using recovery. You can download an app from market which will also do the same "Battery Calibration".
I have same problem too. My battery charge till 75 % and then stopped, i charged it on turned off and then turned on. I tried to install Battery calibration but this app doesnt let to calibrate battery till is not on 100 %. Also I tried to unroot the phone, some say that it will helo but still useless.

@Justin5 : "Also I tried to unroot the phone" if you haven't unrooted it then you can try to delete the batterystats.bin file from recovery(explained in the previous post). If you have unrooted your phone, then you will have the stock Sense ROM v2.2. In that case also, your battery backup will decrease.
So, better stick to any custom rom. I am now using SplashMOD v1.6. Its fast, stable and backup is also good with some customization. You can try CM-7,RemPuzzle also(try searching in CM7 post for the stable ROM, you can read reviews to get a better idea).
Note: You haven't told of the ROM you are using.
Batterystats.bin contains information about what uses the battery doesn't it? I don't think it tells it how much charge to hold + it gets deleted everytime you wipe and flash so I don't see how deleting that file can help.

I was reading an article on this the other day in the android forums,and I believe it was saying that wiping the battery stats does absolutely nothing even in regards to calibration. I might have read wrong but I'm sure that's what it was insinuating.
one minute it works,the next it doesn't......yes that's right its the crappy xda update.

Battery calibration does work (at least it did for me, when my battery discharged in 1 hour on my and worked normally after calibration on my tablet)
Don't shoot the messenger lol.the article (not me) was saying that just a good old discharge and recharge is enough and wiping stats is pointless. If I can find it I will link it.
one minute it works,the next it doesn't......yes that's right its the crappy xda update.
deteling the battery status can work but if the battery has some damage will stay that way, i hate the battery for the wildfire, it does not last very long...

I also noticed the difference before and after wiping the batterystats.bin when I was in SplashMOD v1.0. The backup also get increased if the battery is charged through USB till it gets 100%.
But, If the phone has been continuously used without the complete charge cycle, then the battery life will get decreased.

I'll say it again for the hard of hearing, Its not possible for batterystats.bin to affect battery life in any way.
When you go to settings/battery where it tells you what %of the battery has been used by what, that is the only information stored in batterystats.bin and nothing else, it also resets itself every single time you fully charge the phone so no need to wipe it as chances are you already have not long ago.
Yes discharging the battery fully and then recharging fully will prolong battery life, but its not always practical to do so and even if you do, all batteries will come to the end of there life sooner or later.

Is wiping battery stats in cwm still not recomended on gs3?

Is wiping battery stats still does more harm than good?
And is there no need to do battery calibration by charging all the way and wiping stats any more with these new phones/batteries?

I read somewhere that an actually Google Developer stated that Wiping Battery Stats does not in any way improve your Battery Life. I will try to find the source for that. As for calibration, if I am not mistaken, with the latest technology for phone batteries this is no longer necessary, but is still traditional practice for many people.

Yeah I read same thing.It stated that wiping battery stats damages battery life because stats keep track of how many charges battery has left and other things.
So wipe battery stats is only use full if I'm switching batteries?

Still don't wipe. There is no reason and it will automatically calibrate the battery if needed within a cycle or 2.

Because at one point it was believe you had to do that in order to calibrate your battery. Plus when you flash a ROM you can wipe just to see what you get on the first day

I used to wipe battery stats every time I tried a new ROM on my Epic, which for a while was weekly. I know that it quickly became a problem: the battery would never fully charge, the reported information was off by a wide margin (like saying I had 50% left but then two minutes later it shut off due to no battery left), etc. Since then I've never wiped battery stats just for fear of that happening again.
Maybe it would do no harm on a SIII... maybe I just had a bad device or battery or something back then... basically, I don't know for sure if wiping those stats was ever a real problem... but, I know I just won't do it now unless I know to a CERTAINTY it's something I NEED to do, just to be safe.
You know when you go settings battery and get that graph? Then you how that graph resets after every cycle? Every time the graph resets the battery stats are wiped
Edit: so what the guy posted above me doesn't make sense because android does it after every cycle

Had same problem on my Epic Touch.Phone would have 50 percent left and after reboot only 10.But I only wiped stats once of twice so I don't think it has anything to do with that.

Are you sure they're wiped every time? Are you sure there maybe isn't some cumulative stats that don't get wiped? Are you sure there isn't maybe some subset of the stats that get wiped while the rest don't (or vice-versa)?
I ask because I can't say I'm sure of that. I DO know that at least with the Epic what you describe CANNOT have been the case, otherwise any battery stat kinds of issues would have went away with a simple reboot and that just wasn't the case (and I know I was not alone in this by far). While I can completely believe that some aspect of battery stats get wiped with a reboot I have a hard time believing it's a simple as EVERYTHING getting wiped and that's that... unless this is something new with the GSIII or even ICS I suppose.

to quote a google engineer
This file [batterystats.bin] 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. That is, it has deeply significant things like "app X held a wake lock for 2 minutes" and "the screen was on at 60% brightness for 10 minutes."
It has no impact on the current battery level shown to you. It has no impact on your battery life.

[Q] HTC G2 Wrong Battery % Reading after custom rom flash

i recently flashed an ics rom to my htc g2, after flashing it all worked perfect but the phone was reading the battery incorrectly.
do any of you have the same problem? if so do u know of a way to fix this??
wipes battery stats in recovery, charge fully (let is sit overnight to be safe) wipe battery stats again in am. let it drain to around 15% let it charge full (again overnight if possible) then see if you good, i have ocd so id probably wipe stats again just for safe measure.
if this wont help more info will be needed to trouble shot your problem

As far as I know, battery stats are wiped every time you unplug from power with a full charge.
Also, battery stats have nothing to do with the battery % indicator.
Please read this and this.

yes I've read similar articles to those before, thing is I don't belive it wil give you more battery life, that's just silly. for the occasional time my battery indicator has been off, and rebooting alone doesn't work, wiping the bat stats does. now maybe this has just been a coincidence but it has never failed me. if it happens again ill just plug and unplug my phone to see if it helps... or ill just stick with wiping the stats and won't complain if it doesn't work

hey guys... ive done the battery status wipe but no luck my phone reads the wrong battery percentage. idk what to do now. last thing im thinking is reverting back to stock froyo, were battery stats were being read correctly. also i found a gb rom called PantsRom, its based on the stock gb update for the HTC Vision, with all bloat gone and rooted with stock Vision kernel. im going to try that rom out today after i get off of school and see what happens. will post back then. again THANKS SO MUCH FOR THE ADVICE AND THE HELP!
just flashed PantsRom (Android 2.3.3) left stock with all bloat removed. (no overclock) will post back to c if battery is correct. Hopefully itll be okay :good:
battery still wont read correctly. last thing i have left to do is to go all the wayy back to froyo and loose root.. well c what happens then
EDIT - Even after reverting VERYTHING back to stop the battery did not seem to be reading correctly... UUGGHHH!!! PLEASE HELP!
Have u tried running the battery down to nothing?
Run till the phone simply wont stay on and try to charge it to full from there (like over night)
then maybe wipe battery stats again
however i do believe battery stats are wiped every time a full charged is achieved like mentioned above.

That can come from many things. I would suggest to get BetterBatteryStats and see what drains your battery. Can also check under settings/battery to see what's draining it.

Well I'm not necessarily talking about battery drain. But fluctuations. it goes up and down. Drastic changes. Say 50% one sec to 70% a few minutes later. Sometimes the phone will go down to 1% and power down, but when I turn it back on charge could be 30%.

Sounds to me like you need a clean flash. Backup your stuff, wipe everything (don't format sd), and start back fresh.

Looking at my battery graph, it's just a wave lol. Up and down. Haven't checked it that often, but at one point it went up to 71%. After 2.5hrs its still at 61% I had after flashing.

Sorry, it's not very clear. Did you do a clean flash? If so, try to do the factory battery mod (a little search will get you to it). It's a manual way of reseting your battery but must be done when fully charged.
Also, when you cleared your battery stats, did you do full battery cycles?

Umm did you drop your phone? Also, check to make sure the connections are clean.
If everything fails, might be the battery itself and you would need to call your carrier.

Battery Calibration[Root][No recovery][APP][02/05/13]

BATTERY CALIBRATION
Hi!
As we know when we install a new rom we sometimes have battery drain or when we flash a new kernel etc..... what is this?? this means that your battery goes to 0% very quickly!
The normal steep is goes to recovery and wipe battery stats!!
but what i do if in recovery don't appear something like wipe battery stats??
simple!! be sure that your nexus is completely charged,download this app ,, tap on battery calibration !! (after that charge your nexus without break)and congratulations.... buy a beer and make a party!!
I don't made this app.... just share it....
i will upload the link in a note pad... why?? simple.... i can't put links!!!
There is no need for battery calibration. Just discharge to 0% then charge back to 100% and you should be good to go.

It doesn't even need to be to zero.
Everyone should go to batteryuniversity.com and read the articles on cycling and charging li-Ion batteries. Then you will be able to make sense of conflicting advice on batteries.

The myth of wiping battery stats was thoroughly debunked almost a year and a half ago. It is a 100% true statement that neither this app nor wiping battery stats in recovery has ever affected anyone's battery life or battery indication in any way, shape, or form.
Want to know why battery drains after flashing a new rom or kernel? Hint- it has absolutely nothing to do with incorrect battery stats- totally disregarding the fact for a moment that batterystats.bin has absolutely nothing to do with battery charge indication.. After flashing a new rom, your device is actually using more battery than usual as accounts are set up and synced. Likewise, after flashing a new kernel, it takes a short amount of time for the kernel to "settle."
If you still believe the myth that battery stats need to be wiped every now and again, there's an even easier way to do it than wiping in recovery or using some snake oil app... charge your device to full or near full and then unplug it from the charger. Voila- you've just successfully wiped battery stats!

Strange battery behavior
It's actually odd, my battery started getting stuck at 100% like a week ago or so, after 11 hrs standby time and 30 mins screen-on time, it doesn't even drop 1%. However, it shuts down normally at 1%. I actually tried so many things to fix this, i opened the back cover and pulled the battery out, i let it run dead and charge it all the way up, but it just seems to like that 100% mark. Since it actually shuts down at 1%, i wanted to make sure it's completely dead, so i booted into recovery and oddly, with max brightness in twrp, it took about 15 mins for the device to completely shut down.
Any ideas what might fix this?

Bear in mind that you optimally do not want to discharge the battery to the point of shutdown. Doing so shortens its lifespan, and can trigger the N7 to go into a hibernation mode on order to protect the battery from permanent unrecoverable damage due to a deep discharge.

The app has nothing to do with it as the only thing it clears is the list of processes that have operated on battery since the last full or near full charge.
The only "calibration" that an end user can perform entails a complete discharge/charge cycle. This resets the flags for the battery's internal fuel gauge.

Is there a fix for stuck battery percentage? My tablet was working fine and all of a sudden I realized it was being stuck at 100% regardless of how much I used it.

Naja is 99% correct. It's not the only calibration you can do (you can wipe stats), but it's the only one you should need to do.
batteryuniversity.com has a couple of good articles on the care and feeding of Li-Ion batteries. There is a lot of less than accurate info that floats around about batteries. The above site is a good way to learn the difference.
