what's the deal with calibrating your battery? - Atrix 4G General

I read on here that it's always a good idea to calibrate your battery when:
a) you have a brand new battery.
and
b) everytime you flash a rom/sbf/or whatever
Then I also read somewhere that calibrating and re-calibrating your battery too much isn't good for the battery.
I just flashed 1.83 and Gingerblur on my phone.... I literally flashed my phone like 5 x in the past 2 days, should I re-calibrate? I'm worried that if I keep re-calibrating my phone I'll bork the battery... any advice?

nothing bad will happen to ur battery..the battery calibration file is part of the android system and helps the system to determine how much power is left in an accurate manner..it doesnt physically alter the battery in any way. the more likely source of 'damage' would be from constantly discharging fully the lithium-ion battery and u'll hear ppl say that this is bad for these types of batteries.
as for whether or not u should calibrate.whenever u flash/etc. the calibration file gets replaced by the one in the rom/sbf/etc...since the calibration file was originally generated by another user's phone, it has the potential to be 'inaccurate' with ur own battery...running the calibration program could help make it more accurate.. hope this makes sense

Recalibrate WM6 For Mugen 3000 mA Battery

I have recently purchased a Mugen 3000 mA battery. I am thrilled with the extended battery life after fully charging and discharging it three times as recommended by the manufacturer. What I find annoying is that WM6 no longer gives accurate information regarding remaining battery strength. If I run the battery down to 2%, remove the battery and restart WM6 says 37%. At 2% I can repeat and WM6 still says 37%. After running down to 2% a third time and repeating WM6 says around 10%. After that it varies a bit but you get the picture.
What I would like to know is if one of you geniuses out there has discovered a registry edit, hack or 3rd party software that will provide accurate battery info so I don't have to be distracted by having my battery say 2% for hours on end or repeatedly remove and restart.
BTW, BatteryStatus Ver. 1.04.200 beta2 build 0173 reports the same incorrect info and so does SPB Mobile Shell 1.5 Home Tab.
Thanks in advance for your informed guidance. OK, that is laying it on a bit thick but I always highly recommend this site to anyone I know interested in really learning how to take full advantage of that little computer in their pocket.
Take a search on XDA for Ariel monitor maybe it solves your problem.
Thanks for the suggestion. It is a nice little program but it suffers from the same problem. I suspect I need to find a way to change the mA capacity WM6 bases it's battery calculations. I don't know if that can be done with a registry edit or if there is a third party battery monitor that has an option to change the battery capacity for calculation of percentage remaining or better yet auto detects the actual battery capacity. Ideally it would be able to both accurately read remaining percentage and make reasonably accurate time remaining estimates based on current and historical battery drain data.
It is like driving a car with a broken gas gage. Sure, you can use the odometer to estimate how much gas you have left but you are always worried your estimate is off and you will be left stranded without a phone ... oops crossed metaphors.
How do the rest of the users with extended batteries handle this irritating situation?
Bump. I can't believe i'm the only one with this problem.
I know this problem also i will wait with buying a high capacy battery until i find such a hack
The Kaiser uses a smartbattery. The battery capacity is based on the information that a small processor inside the battery tells the phone's main processor. There are several things that could be the problem:
1. The small processor in the 3rd party battery is programmed with the old specs for the standard battery. The is nothing you could do about this.
2. The small processor needs to be calibrated. You would do this as follows; set your phone to never turn off no matter how low the battery got. Now, run the phone down until the thing dies from lack of power. Then charge it all the way up. This should fix that issue. I don't recomend doing it many times, because it is not good for Lion batteries to be fully discharged too often.
This is a very valid issue which I have faced many times when using a 3rd party extended battery with other phones.
Not sure how to solve it though, although I have the 3000mah on order myself.
I think the battery reading is given by the battery itself, and most of these 3rd party manufacturers don't really care to put a smart processor in the battery (to reduce costs/make it smaller/etc).
I have the exact same issue and although it is a nuisance, I have found a workaround to keep using the phone. Simply physically removing the battery and replacing it will increase your remaining battery power substantially. I normally wait till the first low battery reminder to do this. Also, how do I set the phone to never turn off no matter how low the battery gets? This would also be fine with me.

I didn't run into this issue until I reflashed my ROM to one with W6.1. Then, rather than get 12-13 hrs with my 3amp battery, I'd get 6. I used my original battery, but when I put the 3amp back in, I still had 47% left.
It's the ROM, and until there's a fix, it would be a pain to pull and replace the battery just to work around. I've done this several times recently when I'm on battery power, but I'd rather not.
Anybody heard of any other fixes, outside monitor, or do we wait until we get a Windows Mobile 6.1 fix?
Still no luck?
Hello,
Has anyone been able to find a solution for this. I am ordering the extended battery today. I will try to fully discharge it and then recharge it as was suggested and report back.
I emailed Mugen. We went back and forth with them trying to troubleshoot whether it's the battery or OS. They were clueless, but did offer an RMA to replace the battery. I pay the postage. Not sure if I'll send it back if it's the OS. I pull and replace the battery right now. It's a real pain, and I hate opening the case so much, but it's the only way I can get an accurate read.

The processor is required for these types of lithium ion batteries because it regulates the charging of the battery. If it didn't the battery would not charge properly, or maybe not even charge at all.
There is no solution for now, people from other forums tries to patch battdrvr.dll.
But two things may help a little:
1.You may completely disable battery monitoring
HKLM\Drivers\BuiltIn\Battery rename or remove string battdrvr.dll
But you lost monitoring completely.
2. change HKLM\Drivers\BuiltIn\Battery\Order change value from 15 (in my case) to 0. - After this battery lasts longer until power off.
There is not complete hardware or software solution for this problem. We need to wait.
Low Battery warning:
By default, a PPC will sound a warning sound when the battery is running low (10%, fixed value), but there's no way to disable or change the notification. To enable this, so that it is visible in the "Sounds & Notifications" control panel, set:
HKCU\ControlPanel\Notifications\{A877D663-239C-47a7-9304-0D347F580408}\Default = "Low battery warning" (REGSZ string, no quotes)
Anybody have any updates on this? I have noticed this more on WM6.1, but it was still an issue on WM6. I just find this so annoying!
Is there any radio that can fix this? I noiced that this battery reading issue only occurs when the Phone Signal is on. When off, it never happens to me. Or it seems. So it has something to do with the radio.
bump, anyone got a solution?
this is very interesting, i bought the seidio 3200 battery i am having the same problems. i just tired the
change HKLM\Drivers\BuiltIn\Battery\Order change value from 15 (in my case) to 0
i am going to see how that works out throughout the day
Tried It
I am having same issue, reset the registry key to "0" and ran for a full day, no change, still incorrect reading. I have a 2700 Mah battery and the charge indicater is completely wrong on it. I have cycled the battery as per reccoemndations, but still get wrong power remaining readings. Can remove the battery and resets itselft to a more correct reading.
I am out of ideas, guess we need someone from HTC to chime in with a hardware fix.

i have tried it too and it still does the same thing. i would still need to pull the battery and restart the device for the batt meter to get a more accurate reading. i could do it about 3 times before the battery dies completely.
is there this problem with all extended batteries or just with the larger ones?
the reason I ask is that I've got a $17 credit at Amazon and was thinking of grabbing a 1600mah battery, it's only like $22 with ship so I'll only pay a few bucks for it really...
I wanted to get the larger one but it's fat and won't fit standard carrying case, but the 1600 is slim and will fit in place a regular battery

Editing batterystats.bin

I just had an idea if it was possible to edit the batterystats.bin file. This way we do not have to calibrate whatsoever and possibly "trick" the phone to use the battery longer before shutting down.
As I understood from the forums, full charge 100% is around 4.2v and flat 0% around 3.5v. This bring us a delta of 0.7v = 100%. If we could edit and write say 3.3v at 0% then we would gain 0.2v and extend the battery life for another 20%+?
What do you think? Probably for a start, those with excellent battery life could help to post their batterystats.bin file and let the others with draining issues try out your calibration file?
Well it wont work.
First that file is basicly a logfile.
Second the sgs need that power to work right.
Third you can damage the battery if you try to lower the power to much.
So if you want better battery time you need to se what app you use and that kind of things.
You can also buy a battery so you have more power.
You can also try to change it under the day.

Thanks for the reply.
Just thought that since the phone load is the same and thus power consumption rate remains, only possible issue would be the battery information to the phone is not accurate:
battery is either not yet fully charged before the phone cuts off charging and/or the battery is not yet fully depleted before the phone force shutdown thus showing the 'effect' of fast drain

Well all is a calculation on the power in the battery, but the phone need to now what is the max value and the low value the battery have to make a right calculation. Thats way it often works to delete the file when you have full power.
So its very hard to use others file, it will not be how your battery is.
Maby there is some place in the system you can tweak this, but its not good for the battery to over load it or lower the power to much.
MAby you get a better battery life for some time, but the battery will get broken and bad alot faster, then you need to buy a new battery. So i dont see any gain on that..

effective battery calibration

How do you calibrate your NookColor's battery effectively using the Battery Calibration app by NeMa? I've done it a couple of times and I'm quite unsure whether it did anything good on my battery... On my personal opinion, it just made it worse. Or maybe I did something wrong. It says there that it's recommended to wait for 100% before you calibrate. I did that. It also says that it's recommended to have the battery drain after calibrating, then charge to full without stop. I did that. But after all of I've done, I did not notice any difference, in fact I think it just got worse.
Did I do it right? Can anyone post a tutorial/link that can teach me how to do it right?
You did it right, but I doubt it made anything worse. Let it go through a couple of charge cycles before you pronounce it bad.
All it does is wipe the battery stats and then the OS starts "learning" how the battery works again. It doesn't really change how well your battery works, it just helps the OS understand how the battery works so it can properly report it to you.
try battery left.
From what I have heard, in order to make a successful re-calibration you have to let the Mv charge up to at least 4200 before you begin the recalibration process. I'm not sure what the max Mv is, but another check would be to let the light on the cord turn fully green first I think.

tips on how to improve and calibrate your battery

Some people get battery life less than others and the simplest most common answer is the battery calibration. There are so many other reasons to take into account from having defective unit to what are you using your phone for. people spending more time on light apps such as simple chat app will get alot more screen on time compared to other who spend more time playing heavy 3D HD games. Additionally, wifi, 3G/4G, GPS, auto sync, bluetooth, NFC and brightness of the screen will have an impact on the battery life thus screen on times, so you should take into account all of these things. Comparing screen on times is useless as you don't know what the other person was doing during the screen on times and what other things were on.
Therefore, I decided to make this topic. I saw people complaining that their screen on of there phones is alot less than others, although they have all other services off and brightness to the minimum. before going into calibrating your battery, you should check whether your phone is going into deepsleep as expected or not. If not then this is what is draining your battery, you can use wakelock apps to check if any thing you installed preventing your phone from going into deepsleep.
Apart from previous reasons, calibrating your battery could be the solution. First, you should note that you need to do this once every ~2 months (avoid doing it alot). There are so many ways to calibrate your battery, and I will mention two here:
if you are rooted:
1- run down you device's battery until it turns itself off
2- charge it until it is 100%
3- use any app from the play store to delete batterystats.bin
4- you can stop here but the following steps will speed up the calibration process
5- repeat step 1
6- charge it fully without pause
7- use your phone normally and the battery will improve in the next few days (steps 5&6 should speed it up)
if you are not rooted:
1- run down you device's battery until it turns itself off
2- charge it fully without pause
3- turn it on
4- wait few minutes
5- charge it for one hour
6- use your phone normally and the battery will improve in the next few days (repeating 1&2 should speed up the process)
if anyone has any suggestion or comments or if I made any mistake please let me know.
please hit thanks if I helped in anyway
What to do after calibrating your battery?
now you calibrated your battery, you need to understand few things to squeeze the most out of your battery. the basic answer is to monitor your battery and avoid things that drain your battery. so what uses more battery, I will but list of things that use the most battery in order (what use the most to the least). The list came from me monitoring every single one alone (it might not be accurate)
1- Processor
2- screen
now people would say that screen uses more than processor. In order to test this, charge your phone to 100% unplug it and directly play heavy HD game for 30-60 min and go and check battery stats, you will see the game no.1 then screen no.2. the problem with the processor is that when it heats up, it wastes ALOT of battery as the heat is just energy came from the battery. if you want to extend you battery life, you should start with these two as they use more battery than everything else. To make it simpler I would say 1 hour of screen on uses battery enough to keep your wifi on for >1day (and I mean wifi not the whole phone with wifi on)
Recommendations:
a- avoid using apps/games that heat your phone (most games does, but try to avoid when possible)
b- Avoid using your phone while hot (this will degrade the battery and the screen and will hurt other internals such as processor in the long run and will also waste too much battery)
c- underclock your processor if you play to much heavy games (to protect your phone from heat and extend battery life)
d- reduce the brightness will save you good few hours of use
3- auto sync
4- 3G/4G
5- wifi
I put auto sync first because in order to have working auto sync, you will need wifi or data + processor to process what are you syncing
6- GPS
GPS actually consume more battery than wifi when both are working, but the good thing about GPS is that if it is not in use even if it is on, it doesn't use battery unless it was needed to locate the phone.
Recommendation
Turn them off when not needed. There are certain apps in the play store that turn off wifi, data and auto sync when screen off then turn them back on when screen is turned on. I use tasker which does this and check for downloads before turning off wifi or data.
you are more than welcomed to add any tips or make comments or suggestions
Are you sure you are talking about Xperia Z1 and not lets say Nokia 3310? You should not overcharge modern batteries, as they dont have the memory effect. In realoty discharging it to 0% and charging to full will actualy make battery worse and cause decrease of battery life. You should also avoid charging overnight if you want to keep your battery in good condition. The best thing to do is to keep it between 15% to 85-90%, and dont let it discharge/overcharge.

I do understand what are you talking about and I do know about battery memory. But you still need to completely discharge your phone once every ~2 months for calibration purpose. But you are right about overcharging it. I will modify the main topic to make these changes, Thx

No you don't, that's completely unnecessary with modern batteries.
Also, wiping batterystats.bin just clears the info in the battery usage page in settings, it gets wiped automatically every time you charge over 90% and has nothing to do with calibrating the battery.
So much misinformation in this thread.

you could have said it in a better way. any source about what are you saying?. There are tons of sites that agree with what I said, a quick search found this
http://gizmodo.com/how-to-take-care-of-your-smartphone-battery-the-right-w-513217256/1416982678
at the end they said this
"To get the most out of a lithium-ion battery, you should try to keep it north of 50 percent as much as possible. For the most part going from all the way full to all the way empty won't help; in fact, it'll do a little damage if you do it too often. That said, it's smart to do one full discharge about once a month for "calibration," but don't do it all the time. Running the whole gamut on a regular basis won't make your battery explode or anything, but it will shorten its lifespan."
and regarding wiping batterystats.bin. There are tons of articles and apps the recommend this and so many people said that it helped them. it is not just useless because you said so, unless you have strong evidence which I want to see.
This is old advice. With the new technology batteries it is not advisable to completely empty the battery.
There is no need to "condition" the batteries and they do not suffer from "charge memory"
Plus, there is already a thread in this forum about battery handling and tips

Sudden battery drop, 70%-->0%, on newly replaced battery

I have replaced my battery with what should be an original battery for the Huawei P8 GRA-L09, battery nr: HB3447A9EBW.
After having assembled the phone again I experience some weird issues with the battery level dropping from 50%, 60%, 70% or even 100% in an instant. I have tried calibrating the battery by letting it die completely, recharge to 100%, let it drain completely again and recharge to 100%. I have tried different battery calibration apps and a factory reset - nothing helps.
I contacted the company I bought the battery from and got a replacement - still same issue.
Unfortunately i damaged the original battery when taking it out, so i cant use that as a reference.
All stats seems to be similar on the new batteries as on the old one, but for some reason the width of the new battery is a few millimeters smaller than the old one, meaning that it does not fill out the space completely. Has anyone else experienced the same?
Any suggestions on what my problem might be will be most appreciated!

Yeah, my replacement battery was also smaller than the original one. Also, I was getting sudden drops from 9 percent to 0 in a minute. After disabling Huawei Perfhub (Root access required), the drops were gone.

I guess, they are trying to do some kind of trottling by showing unreal percentages. Something like what Apple did with the iPhone 6.

Rename /system/bin/perfhub file to something else and test. If it works (Doesn't work always), you will see a slightly different battery stats page.
How can I locate the perfhub file, It looks like there is no such directory in my mobile's memory?
