Hi guys, I bought 2 batteries so I could play longer (info here)
I charged one and replace my original battery. At that moment my original battery was at 70%. I put the new battery and with shock I see that the battery level was 70%, the same level that my original SE battery.
I think battery level got stuck somehow. Is there a way to fix it or is a battery problem?
ADDED: while I was writing this post, my battery went from 70% to 80% without been connected to a USB cable or charger... extrange.
I think it has something to do with the battery stats not being tuned to the new battery. I wish I had more info for you, like how to reset the stats, but I can't recall on how to do it, as I have yet to do so myself lol. I just remember reading about it here at xda....maybe under accessories section.

Ye its not your battery thats screwed anyway just let ur battery drain then charge it to 100% & wipe stats, u can do so by searching for battery calibration app on playstore. It comes with instructions and is simple. It just deletes a file for batterystats inside data/misc I think ( I havent had to do it in a long time ).

Turned on my Desire HD today and used CurrentWidget during the first charge, now its on 100%. But when should I calibrate the battery?
- Can I do it right away, or should I wait for the battery to be drained?
- Should I calibrate it with the phone being all new, or should I do it when I feel like the battery is getting worse? (Couple of months?)
I wouldnt recommend calibration until youve got at least a week of normal use under your belt or you wont see any kind of improvement
When u notice unusual battery drain u could try to calibrate it but a new phone shouldnt need it perse.

I need to figure out exactly what's causing this battery drain. At 7PM my battery was at 100% after installing a new radio+kernel combo. I also calibrated my battery using a method I read in the Calkulin thread for his ROM. The method was as follows: After installing a new radio, rom or kernel charge the battery to 100% then physically take the battery out for 3 minutes. Boot into recovery then wipe the battery stats and dalvik cache 3 times each. Boot into Android then charge to 100%. Download a battery calibration tool use that and discharge. Anyway, I did all of this and was done by 7PM. After light use...listening to a few songs via google music...did a search using 3g...nothing too heavy. By 8:23 my battery was down to 76%. I thought this was pretty abnormal so I downloaded some extra battery tools and app watcher tools to see exactly was draining me so bad. Over the course of about 1:30 hours my battery dropped from 76% to 46%. I froze some non essential apps after checking up on them with watchdog (social hub, yahoo finance, tts service and accuweather). Decided to do a restart to see if that would help and my battery read 17%. I just noticed that it went up to 18% and it's holding steady but this is really weird...I honestly don't know what's going on and I could really use some assistance with this issue.
I forgot to post stats for the past few hours. Before I started the battery drain quest the Battery Monitor Widget said that the estimated was around -280mA. Over the course of a few hours it ranged from that to well over -600mA. After the restart it dropped to like -2mA but now it's back up in between the -400mA to -700mA range. It's slowly dropping as I type but there's no way that this is normal.
Sometimes when doing reboots messes up the battery reading. Its done that to me before. I have noticed that on ics when I flash a kernel and modem it takes me like a full day to get good battery. After I flash it my battery is pretty bad. Search for an appstore called bettery battery stats. Its on here at xda somewhere. Use that to see if your phone is sleeping properly or if an app is wakelocking your phone. Also it depends on who u ask but wiping battery stats does absoutley nothing for me. Its been said before that it doesn't work. Hope u get it straightened out.

thanks for the response. I've downloaded the battery stat app but I need to read up more on it to find out what the program is telling me. In your opinion what is good battery drain? I was on facebook for a second and it skyrocketed to high -600's but now it's down to about -90mA and dropping by just sitting in front of me.

Clearing battery stats does work to wipe any info the os has on the battery. Just check your battery graph in settings, boot to cwm, wipe battery stats, then look at that graph again.
I know you know your fair share of info, so no disrespect man...

I think he meant wiping does nothing to actually effect the life of the battery... Which, I agree. I've never seen any benefits when I've done it on my ET our my Moment.
Wiping just resets the OS's experience with the battery. Using your phone normally for 24 hours had the exact same effect.

things were looking up as far as battery life goes. i got rid of some programs that were hogging the cpu and i was almost to around 12 hours on a single charge with light use. however, i did a reboot at around 6pm and my battery read 45% before hand. after the reboot it read 10%. do you think it has something to do with the kernel? this is the second time a reboot has jacked up my battery.
Guys
I have been having the same problem and try lots of things but what I did not try and just found out is that my phone has a 1500mHa instead off a 1800mHa Sprint store made a mistake and placed the wrong battery inside my phone.
Maybe some of the problems you guys are having is due to that fact.
Besides opening the phone there are several app that will actually tell you which battery you have I.E. Battery Monitor
My wildfire s battery life is very bad.
When fully charged,the phone works for a long time without even 1% drop but when it goes down to 99% then battery began to discharge quickly.
Is there any way to solve this?
HTC is popular for having low battery life so it can't be blamed but
U can underclock it

solution
in my case, I left the phone to discharge and shut off completely. Then, with the last drop of battery juice, I powered it on into CWM recovery and went to advanced -> clear battery stats. Afterwards plug it and charge it to 100% (until the LED turns green), preferably with the phone off.
I know some say it's only a placebo effect, but in my case it makes my 806Mhz overclocked & automatic sync enabled phone to last around 35hours.
You dont want to empty battery in our wfs completely ever
Lition-ion batteries dont like full dischard and they tend to loose juice after that process
Good tip-never discharge your phone so you can't turn him on without charger
My battery life sucks, I think its the quality of HTC batterys, I need to go on eBay and buy a new one
Sent from my HTC_A510c using xda premium
my battery is doing the same, plus it never charges 100%, stops on about 90%, after few hours of charging it gets to about 91
I've never had any real problems with my battery life, but with the CM9 that I'm running as a daily at the moment, it just can hold up a long working day till I get home. Really annoying, but damn I like CM9 to much ! I hope that get's sorted quickly!

Agree with that,its quite correct.
Also guys try this...
-HTC checkin service apk...its a bigeest consumer next to wifi,cell,and display...amongst two top ones.
Do following:download rom toolbox or titanium backup or any similar app
here the links https://play.google.com/store/apps/...wxLDEsImNvbS5qcnVtbXkubGliZXJ0eS50b29sYm94Il0.
https://play.google.com/store/apps/...DEsImNvbS5rZXJhbWlkYXMuVGl0YW5pdW1CYWNrdXAiXQ..
with this in app manager find that app...long press on it and choose FREEZE (u can unfreeze it later if you want)...also freeze the maps if not using them...etc...just DO NOT MESS with system apps if you dont know what you are doing.
I prefer Romtoolbox cause its all in one app...you can also wipe your battery stats from there as well...great app for root users...try it out
Hope i helped with giving some of you some ideas what can you do amongst other battery tips im sure you all know by now.
Enjoy
Battery calibration
if you use a custom rom you have to calibrate your battery with néma's battery calibration you can find it on the market .my battery last longer since i did it at any rom instalation
@Fikus011
I freezed those two apps with titanium backup.i wil report later about battery life.
Thanx for the info.
@TheKilLapops
I had already use battery calibration
BTW thanx

Hi everybody!
i've got a little doubt about the battery calibration method and tool..so...i've done all the process(the one suggested by the user Ganymedes with the battery calibrator from the market) every time i flashed a new rom update(in this case the sandvold ICS),for calibrate the original 1400mAh desire battery,and also because my desire shutted down at around 15% battery remaining..and every time without any positive result..so i tried in many ways,and at the end i kept the battery as it comes out after all the times i tried to calibrate it...but now,i just bought a brand new high capacity mugen battery..the bigger one with 3200mAh,'cause the old one drained too fast..so,the question is..i've got to recalibrate the phone again,'cause i changed the battery?..i wish to precise that i haven't calibrated the battery after the last ROM update..so,what you think?'cause i read that the battery calibrator app will save and make permanent the battery stats..and i'm afraid that an old batterystats with the info from the stock battery is still saved..misreading the power of the new battery!
thanks for all the answers!
Is far as I know the calibration configuration is saved on the battery not on the rom.

So you need to calibrate it because you replaced the battery.
via xda app
Cycling the battery through one full charge and full dis-charge cycle should do the trick. I don't think a calibration tool will help much. Wiping battery stats is also useless.
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.

o really?? i post that because sometimes when i flash a new kernel my battery percentage lie.... when i had for example 15% mi tablet shut down and i calibrate with this app and mi tablet shut down in 0%... normally...... and i do that always y flash a new rom or a kernel...... maybe i'm wrong .....

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!

OP, stop posting nonsense. Seriously.
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.

i have a question....... i discovered this app because mi battery was giving me problems..... for example...... it charges very quickly .... and when i had mmmmm 15% my tablet just shutdown....... when i use this app, i charged my battery to 100% and i "calibrate" my battery ,and my battery works perfect again, now my tablet shutdown in 0% or something like that..... so that could be called calibration.... o what?
thanks!!

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.

This is all the recalibration the device needs.
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.
