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.

Found this on another forum, I have done this a few times myself (do it whenever i flash a new rom because i always clear battery stats, can't hurt). Have found that it does top it up a fair bit. Before doing this i find my desire will drop to +-93% straight off the charger, however this keeps it 100% longer and i actually get to see the numbers 99-94%
Worth a go in my opinion because it only takes 5 mins of your time and can't hurt the phone... So any minor gain from this process is a win...
Hi *******, I understand your concern regarding battery life on your Nexus One device. The following steps should significantly extend the battery life on your phone. Please connect the phone to the charger with the phone powered on, and allow the phone to charge until the notification LED is green, indicating the device is fully charged. Disconnect the phone from the charger, and power it off. Reconnect the phone to the charger with the phone powered off, and allow the phone to charge until the notification LED is green. Disconnect the phone from the charger and power it on. Once the phone is powered completely on, power it off again and reconnect it to the charger until the notification LED is green. Disconnect the phone, power it on, and use it. You need to use this sequence only once. If the issue of battery life on our phone persists, I recommend you contact our HTC accessory department directly.
Mod Edit: There have been a few reports of damaged batteries by people on this thread. There is a chance that this MAY damage your battery. Please bear this in mind if you choose to follow the instructions above.
supportyou and the app!

Also wondering about this
You should wipe battery stats after its fully green (when powered off) then boot the phone back up.
You only need to do this once
I.e.
Charge till full when powered on
power off
charge till full again
boot into recovery wipe stats
boot and continue to use as normal
It works!!!
That's fantastic!
I read this topic this morning and tried immediately. Since this morning i only lost 4% until now. That's great news!
Thx a lot, man!

Hope this will make battery life better. I have the same problem as described in first post (drops immediatly from 99% down to 93% )
Can someone suggest me how should I go about doing this if I use multiple batteries?
I'd imagine the phone can only be calibrated to 1 battery. But if I were to use another battery, would I screw up the calibration to the original batteries?
Right now as it is with moderate usage I need 3 batteries to last me through the day. :S

3 batteries?!
What rom are you using and how exactly are you using your phone?
I have just one battery and it lasts about 2 days with moderate use.
I am using this ROM: (sorry can't post link)
[ROM] Rooted Official HTC Android 2.2 (FroYo) ROM [Market issue fixed]
With my typical usage, I unplugged the phone in the morning from the charger, by the time I knock off from work, I would have left about may be 20%. With stock ROM and a single battery, there is no way that I could last 2 days with one single charge. My main use is web browsing, RSS, Facebook and IM. My estimation of my solid screen time is about 2-3 hours.
So I bought more battery just in case, and played with custom ROMs. I ended up using up a whole battery in 4 hours or so. Definitely something is wrong here. My gut feel is that both the ROM and batteries are suspects. Being a newbie I really need enlightenment.
Is it really needed to wipe the stats? I think I've accidently done this once already... cause the battery life is much better.
since this procedure, my battery stays at 100% since nearly 2 and a half hours now and i did 2 text messeges in between and recently checked the bat about 4 times
this couldnt be possible..
i mean the battery is almost doubled in comparison to how long it lasts before
is this possible??
yes it is possible

but how?
i mean in this time the battery would have been dropped to arround 97
and now its still full?
i mean these are stats how are they increasing battery life? the batterylife is given from the cell itself?
I have done a bunch of reading since my first flash to Cyanogen's 6.1 but not finding really satisfactory answers.
With the old rooted stock deodexed...I was getting about 14-15hrs of moderate-high use. So basically I pulled the cord at around 7am and plugged back in around 6pm with about 40%.
Was fine.
Flashed 6.1 last night and now I am two hours off charge and sitting at 58%!! I have all syncs turned off and I have no wifi/gps/4g running. The ONLY widget at the moment is weather and it only updates when I hit refresh.
My search has shown something called battery calibration...but that doesn't make sense to me. I have done the long charge, power off charge, power on charge etc... But since I have a wall battery charger I have just moved away from that and occasionally swap out my batteries for a full charge in that thing.
Does that 6.1 REALLY need another voodoo approach to battery life? Also the threads I have found seem to be for the nexus one or the HTC Magic(?).
Anyone else suffering HORRIBLE battery life after flashing 6.1?
Anyone got a link to a fix for the EVO and maybe something that I can get through the day with (do not have my charger at work)?
When I flashed CM7 to my wife's phone the battery was horrible (Less than 2 hours). I recalibrated the battery and the next charge lasted 2 days. Give this a try:
Battery recalibration
If you're experiencing higher than normal battery drain, try the following:
Charge the device to full battery; let it keep charging until the battery says it is fully charged. Do not just wait until the light is green, it isn't always fully charged, causing a lot of inaccuracies. (You can check by going to: Settings -> About device -> Status -> Battery Level = Full.)
Boot to recovery mode and delete the battery stats
NOTE: To have the most accurate of battery stats, reboot the device immediately after wiping the battery stats and wait for CyanogenMod to boot completely to the desktop. Once your entire boot is done and you have full access to the device, go ahead and pull the charger and continue with this troubleshooter.
Do not charge the device until after draining the battery completely, resulting in it automatically shutting off.
Recharge the device completely and then use as you normally would.
Also, CM6.1 or CM7 should get decent battery life. If it still doesn't try flashing a different kernal. I found that savaged zen bfs sbc kernal extended my life considerably.

Yea Cm6 is dated. But that shouldn't matter.. I actually had fantactic battery when I was on cm6, much better than what I get on cm7.
First, check spare parts for wakelocks and make sure you don't have any. After that, follow Fazulkas advice to reset battery stats, follow it correctly tho. I never thought wiping stats would make a difference, but it surely does.
Ok, I'll try that process when I get home tonight. (Guess I can survive w/o a phone for a few hours?!?! :^O) Haven't set up more than just the google account on this ROM as I wanted to test it first. So maybe tomorrow it will win me over.
DATED?!?! LOL! It was only just a final release a few months back...;^) It has all the important stuff working where as 7 doesn't and it is still a RC.
:^P
(Have you seen my sig? Old dogs only try the proven tricks thank you very much. :^)
CM6 is not dated. In fact CM 6.1.3 is the most current stable-release version of CM available!

Its not the ROM. Anytime you flash a ROM, you need to calibrate your battery. By calibrate it isn't the plug in over and over method.
You charge to 100%, discharge it fully. Charge back to 100% then wipe battery stats in recovery. Then use your phone.

There is your problem. Anytime you flash a new rom, you need to give it at least a day or two to fully calibrate everything in the rom.

HUH...this is my fourth ROM flash, first one away from stock rooted and I have never had this issue. Maybe the stock ROMs do not have this issue?
I seem to get really excellent battery life when I wipe batterystats.bin after recharging to 100% at night. After a couple recharge cycles, battery life starts to get a little worse each time. But if I wipe again after a recharge, it adds a good 4-5 hours to my battery life.
I don't know why my phone/battery work this way together - they just seem to. I am wondering if there is any downside to deleting batterystats.bin EVERY time I recharge? Is it harmful to the battery? I doubt it is a problem for the phone but maybe so?
Thanks for any advice.
[EDIT: I realized after posting that this maybe would be better in the Q&A section of forum. I would move it there myself but don't have rights to do that. I'm sorry.]
only need to do it once.... .. i do it once per new rom/kernel.... you have to let that stuff work itself out.... let it chill for a week or so... just run it....
....i put a new rom on... .then kernel.. after i get it configured.. that night i charge it over night to 100.... then before i take it off.. i delete batstat with root explorer.... then unplug it... let it go down... .. charge it back to 100... . i'm telling you.. well for me... my battery last awhile.....i'm on nightly cm with savzen kernel.

Well you only need to do it once after flashing, after that, its useless. You THINK you are getting better battery life, but you are not.
Is it harmful to the battery?
Click to expand...

Does nothing to the battery, the battery will still hold the same charge as before, and discharge the same way. The only thing you are doing is resetting the OS's 0%-100% stats, which again, is only needed to be done once.
You may be getting better battery life because after deleting the file if you aren't following through with the rest of the calibration process. After deleting, are you letting it discharge fully, then charge fully without breaks? If not, do it that way once & you shouldn't need to do it again.
But to answer your question - no, it won't harm anything. If you aren't calibrating properly after each battery stats wipe, then it may mess with your battery life. Other than that, you've got nothing to worry about.

I have to agree with the OP. I've tried a few different calibration techniques, followed the instructions carefully, and let them run their course. But after running a fresh battery calibration there is a noticeable improvement that day - I swear I'm not imagining things... The % starts at 100, then SLOWLY makes it's way down to 90 the way I think it should. Normally that first 10% just disappears into thin air...
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 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!

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.

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.

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.

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.

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.

Wiping stats does nothing in terms of calibration.
