I am using the Anker 1900mAh battery for last 3 weeks and I am satisfied with the battery life it provides. I did 4-5 charge-discharge cycles and now I regularly get 24hrs - 27hrs life out of it. Today I noticed that BMW Pro is showing battery '14% aging'! What does this mean? Is my battery dying? To confirm I installed the HTC battery widget and it shows nothing abnormal. Please check the screenshots. Is something wrong with my battery?
More than 100 views. Nobody?
My aging says 0%, on stock battery... 5 month old.
I gave up using BMW after getting my sensation, the battery driver by HTC is useless and the statistics the driver gives to BMW can't be trusted.
If you're that concerned then charge to 100%, delete your your battery stats and history and hence start again - but I don't think anything has changed for you, it still guesses your battery as around 1900.

Absolutly right about BMW and Sensation. BMW Useless and confusing only. Don't worry about ageing - continue to use as before.
My phone is not rooted. So I cant delete battery stats. And I get excellent battery life. But the 'aging' thing was worrying me. But after reading your comments not so much worried now. What does 'aging' mean anyway? i.e. in the context of the battery.
Over time and use batteries age... They lose their capacity.... Aging 10% Means that the battery has 10% less capacity than it had when it was new....

There's nothing wrong with the app, it worked perfectly on my HD2, it's just the battery driver that's the issue for the sensation.

I know that is Senasation's driver reporting not correct discharge current, only correct charge current. I meant BMW is useless with Sensation.
And i guess it is not problem of HTC's driver but hardware chipset used in sensation and evo 3d - driver can't read proper values from measurment circuit of chipset. If i would be driver itself, HTC could fix it easely.

Don't expect from Anker same quantity of charge-discharge cycles as original battery. It may not work as long as original one(cycles i mean). Nothing can be done with it and nothing can help. They are cheap, so just buy new one when capacity will badly decrease.
Now BMW is showing aging to be 0%. How and why it showed 14% previously I dont know! The battery is hardly 3 weeks old. It cant begin to age so soon, can it? Maybe the earlier value was some wrong reporting. There seems to be a definite problem with the phone's battery driver.
As countless people told you by now - those stats don't mean ****. Stop relying on them. It's useless, confusing information with absolutely no value.
Your battery is fine.

^ What he said. If the developer set the app to say it's 99% aged while your battery still lasted about 25 hours or so.. would you believe that? I'm banking on the assumption that you're not a complete moron and WOULDNT believe that. This is almost the same thing, accrding to all the other users, the app and the battery drivers don't work well together. As everyone else has stated, stop using it? There really is only one way to test your battery properly, and that is to use it. If one day you only got like 15 hours out of your normal 27.. then you know there's a problem. screw the bmw app

You may see what are aged battery here :http://78michel.unblog.fr/htc-desire-battery-shutdown-analysis/ and here :http://78michel.unblog.fr/?p=164
The SoC curve ( state of charge) shows a step during the charging cycle before reaching 100% and a shutdown while discharging. This is very typical.
The aging is in fact the amplitude of the step.....
A precise battery analysis requires a full charging cycle from 0% to 100% with a AC charger.
Your battery is clearly not aged at all..... don't worry

Folks, wiping battery stats is to no use. It only contains the data of what have used the battery since last charge. When you unplug your phone from the charger, the stats are reset. You can't extend or damage the battery life by deleting/altering the battery stats file.

why would you want to do that?? i thought that with new lithium batteries it's better for them to charge them as much as possible, whenever possible. and AVOID them to go to 0. That could kill it, for good! Someone please, tell us if i'm wrong. These are not the oldschool batteris with "memory". So no reason to get it to reach zero for any reason, than destroying it.

Li-ion batteries do not suffer from the "Memory" issue as much as others, but they still do to some extent. The biggest issue with all Li-ion batteries is once its charged if you leave it on the charget you will burn it out and it will stop holding a charge.
Running it to near zero before charging wont hurt it, I have done it for almost a year on my s730 without issue and I charge it every few days due to use.
There are rumors that running it to full zero can hurt it and you should keep it charged since it wont hurt it memory / overcharge wise. I usually but not always drain my phone to 10 - 20% before charging to full and taking it off the charger once full. This way I can keep it charged and not worry too much about memory issues.
Ni-MH batteries really sufferd from the overcharge and a little from the memory, while Li-ions are supposed to not suffer from either I have (over retail experience) seen them suffer from both issues as well however it takes longer for the problems to crop up usually.
As long as you are carefull your battery should last a good long time.
I am wrong

I'm going to try to purchase my Nexus S before class tomorrow when they open. Don't want to take any chances on it selling out. Would it be wise to turn it on and use it a while during the morning? Or does the battery need to be fully charged before using it to condition it and ensure a good battery life? I've read many battery tips but i'm still a little confused on whats better for a new battery.

When you get it, deplete it, but do not let it die. Ever. Then just cycle it normally.

Yes, by letting your battery "die", per se, you're letting it deplete to 0%. I'd say for safe measure, between 5%-9%. But if you're in the vicinity of a charger take it down to 2%. If not, turn it off at 5%, then plug it in before powering it back on. My devices' daily life lasts so long (on all devices I own) because I properly know how to cycle a battery.
If you let your battery die (0%), it'll lose more and more charge (on a 0.00% level) every time. When you get it tomorrow though, it should have ~50%-60% charge.

Battery life?
So how are your batteries doing? Mine is kind of crappy. What supposedly changed in 2.3? I see no difference in the reporting of apps in Battery Use and they took away Battery History in the hidden system settings. Where is the graph everyone talked about?
You gotta give it a few charging cycles for the battery to reach it's full potential. Give its few days, you'll notice it will get better after you charged it a few times.

The battery life on mine is chugging along pretty well. I gave it a full charge before hitting the streets. Its been 4 hours with wifi and GPS on with a couple dozen pictures taken and a bunch of apps dl and installed. used maps 5.0 and periodically hit the GPS for my position getting really good accuracy while driving and the battery level still has a little more than 4/5s battery life still remaining

how do I train my battery it was halfway charged when i got it do I let it die and then put it on the charger thanks!
EDIT:WRONG SECTION DELETE THIS MODS!
I've always charged all the way up then ran the battery all the way down, then charged all the way up again. Then periodically, I will run the battery all the way down just to give it a little exercise. So far out of all the cell phones I have had I have had 1 battery go bad on me, that was 8-10years ago.
Battery
how do I train my battery it was halfway charged when i got it do I let it die and then put it on the charger thanks!
matter of opinion really.... I would kill it by playing with it.... then do a full charge
that is what I am doing
Generally the suggested method is to charge it for 8-12 hours as soon as you can, then use it until it gets very low, then charge for another 8-12 hours. Do this cycle about 3 to 4 times and you've got yourself a healthy battery.
Killing the battery entirely, despite popular belief, can have some negative effects on its health. Especially during is conditioning phase.
Ok Yesterday I charge my phone it said it was fully charge I took it off the charger and immediately went from 100% to 97% did it again today. Is there any way to fix it or does the battery need to be replace??

The steep drop in reported battery seen past the 6.5 hour mark shows the phone being unplugged. While the current draw does increase at this point (since the phone is being used), it still cannot account for the reported 6% depletion in 3 minutes. It should also be obvious that maintaining a 100% charge state is impossible given the long spans in which the phone is only operating on battery power.
Now we can see that the 6% drop after unplugging is simply the battery gauge catching up with reality.
The phone manufacturers essentially have three choices:
1. Use older charging styles which actually maintain a full battery, thereby decreasing its eventual life
2. Use new charging methods and have an accurate battery gauge
3. Use new charging methods and have the inaccurate battery gauge

Just look at the battery work I did with others in my sig. I know about all those topics you linked, but they are a completely different issue than this nexus s issue.
Dianne Hackborn - 6:42 PM - Public Today's myth debunking:
"The battery indicator in the status/notification bar is a reflection of the batterystats.bin file in the data/system/directory."
No, it does not.
This file 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.
Deleting it is not going to do anything to make your more device more fantastic and wonderful... well, unless you have some deep hatred for seeing anything shown in the battery usage UI. And anyway, it is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point), so this would be a much easier way to make it for away.

Is that what wipe battery stats does? I have never noticed any difference when I did that. To think of all the times I have run the battery down, cleared the stats, charged it, and cleared the stats again with no noticeable results.
Sometimes it seems like the battery life gets thrown off by flashing a new rom. It isn't necessarily getting worse battery life but the indicator will work funny like it will show 99% for 3 hours and I will think I am getting great battery life and then go to 30 in the next 20 minutes. It is like the UI gets confused. My tablet will sometimes say "connect your charger" even though the battery and indicator are 100%.
I don't think people realize how much drain the display is on the battery. They flash a cool rom and use it a lot and then think they are getting bad battery life because the display has been on for two hours while they play with it. It is amazing the amount of difference I get between when I am fidgeting with my phone while I am at work (have to recharge during the day) and when I am at home on the weekend and it sits on the kitchen table most of the time (it will generally go all weekend without a charge).
Wonder why its even an option to wipe battery stats with apps or recovery if it doesnt do anything. I never saw a difference myself, I just wiped them periodically cause others seemed to think it made a difference.

First of all those of us who actually knows about Android OS really knows that /data/system/batterystats.bin is nothing more than stats audit. Now if you think you can't actually re-calibrate battery and project that data than your a fool. It has nothing to do with that file.
First of all to accurately predicate it you need a true daemon that's capable of tracking system data with full autonomy access. Second you need correct battery specs from the manufacturer. As reading memory from it may or not even be supported by the device kernel if its not allocated. Thus you see issues with cross link batteries on stock roms, but some is exceptional with similar size, specs.
Now to project the correct data from ~1-100% you need to fully discharge for it to cycle. Yes I know some of you maybe saying never fully discharge Li-Io but if you know the min mV rating then you can stop near suggested mV as it won't go below and damage cells. From then the duration of full charge is defined along with total available mAh. By calculating discharged -mA draw pre scale unit over empty estimation you can predict the true battery percentage.
Ex: ATM my uptime is 14h 47m at 65% with moderate usage (talk, txt, web). Since I have MP1650mAh battery I'm currently at 1072mAh. As its drawing -90mA per scale unit with 4156mV. At this current rate fully projected empty estimation is 9h 38m. Keep in mind my deviceis highly optimized and is on very aggressive battery saving mode.

Man, its getting hot in here. Lol.
Ok, so, if wiping battery stats is useless because it does NOTHING to the battery, is there a way to address the battery and force it to allow a slight overcharge on a regular basis, thereby shutting charging off at a higher capacity?
Please forgive my ignorance gentleman, and refrain from verbally bashing me.
I bought a 1550 mAh Anker battery. If I charge it to 100% and then use it, it stays at 100% for hours. Is this because my phone is waiting for it to drop below 1400 mAh, or what? If that's the case can I somehow tell my phone to consider 1550 mAh 100%?
I ask because of the mugen power app on the market. It intrigued me. Though there is a chance its a bunch.of balogna.

That is THE prime reason people "wipe batterystats.bin" thinking it would fix staying for hours at 100% delay and heavy drop in short time. Which is sign of missing true data. Normally its measured via min/max mV and available mAh. Now by subtracting the used mA per scale unit the empty estimation is calculated. Thus projecting power draw at given duration and near accurate battery metter.

sorry I knew that was another possibility, my mistake. I thought the link you posted some how undermines what I said as you quoted me. As I only posted how to accurately predict and report battery data. Also I think you know who I am...
That is THE prime reason people "wipe batterystats.bin" thinking it would fix staying for hours at 100% delay and heavy drop in short time. Which is sign of missing true data. Normally its measured via min/max mV and available mAh. Now by subtracting the used mA per scale unit the empty estimation is calculated. Thus projecting power draw at given duration and near accurate battery metter.

So with this being said then you don't have to worry about your battery percentage between flashing roms?
The battery life should be still accurate?
I have a 1700mah

Yes, of course it is the prime reason. My question was, is there a way to tell the phone that 1550 is 100% or do I just deal with inaccurate monitoring that is based on a 1400 mAh battery?
Or, alternatively, will android figure it out over time and adjust for me?

answer me this: why in miui does the hardware led light up green when miui tells me im only at 90%? when i check the mv with the battery calibration app it tells me im at 4220 which is a full charge...what makes miui not see that the battery is full?
Before battery calibration, regardless of what happens, I was getting 9 hours, light usage. After battery calibration I get 19 hours, medium use. I'll stick with it with my thick headed self.

I know some people say to fully charge-discharge-charge again the first time you use the device, others say not to do this, others say just fully discharge once a month to calibrate the battery. Well when I first got this phone, I charged it up before using it, then used it down pretty low but not a full discharge, then charged it and used it normally, and my battery life is pretty poor now. Was it bad to discharge it that much on first use? What do you guys do for the first few uses/charges?
You do nothing.
Just charge it and use it. Anything else is just a placebo.
There is no such thing as battery calibration. Battery stats may become inconsistent overtime, but a restart resets them and going down the full charge it becomes normal again. Just... use the thing as Rusty! said. :cyclops:
Thanks for the replies, that's good to hear. What about the fact that I used it down to single digits on my first use (after a charge)? Could this be harmful to it?

The biggest harm you should avoid is your battery getting molten hot.
No.
Thank you all for the replies....very good to know. After coming across a few articles that said anything too low isn't good for it, I was concerned that was doubly true for its first use. Glad to have it cleared up.
