I have about 8 batteries (new & old), and want to figure out which are worth keeping or binning. My thoughts were:
1. Charge battery
2. Reset stats
3. IMPORTANT!!!! Put battery in phone
4. Boot and run Juice Offender until dead.
Does this make sense, or is there another way/app to make it easier. Thanks, Ian
Well, yes and no because atleast in my phone, it takes a while for a new battery to settle so that u truly see how long it lasts. And Juice DEFENDER(not offender,lol ) also needs a good time to settle with the batteries info
Thanks for your post. Actually, it is Juice OFFENDER (purpose - switch everything on to drain battery)
For my purposes I don't believe the battery needs any settle in time. It is after all just an energy source, and as long as battery stats are reset I think the OS will treat all batteries the same. Am working on it, will report back my findings just n case anyone else reads....
Oke amigo
Get the "Nova Battery Tester" app. It has the ability to do a short ~15 minute benchmark of the true capacity of your battery. My >2 year old orginally 1500mAh battery only had around 900 "true" mAh left. I bought a new battery and finally restored my battery life.

Please help i have bought Extended Battery 2400mAh for my HD2 but the battery is discharging same as with normal battery, the strange thing is that when i restart phone after discharging to 0% it says 66% battery again. After that i discharge again to 0% restart and again 53 but these 53 discharge very quickly.
Is there something im doing wrong?
these numbers are from WINMO or Android?...which version/ROM of WINMO?/Android?
Its from WinMo
its Artemis v42/Radio 2.15
Same Problem - suggestion ...

Hello,
I also use a HD2 now with even a 3400 maH-battery. Also I had to notice that discharge is with this battery the same as with 1230 maH-battery.
First: thank you for your tip, I now will try also to restart my HD2 before re-charging.
Second: this phenomena means at my knowledge that battery-controler has problems with recognition of used battery: so I think that HD2 thinks having still a 1230 maH-battery, even if a 3400 maH-battery is used with it.
This could be then in my eyes a software-problem (would be solvable) - or, in worst case, a hardware-problem, meaning, that battery-controler of HD2 is unable to recognize batteries stronger than 1230 maH-capacity.
If you get more knowledge about that, I would be glad if you could tell me.
Thank you very much for proceeding,
inuli
There is one tip try it :
Discharge battery till phone turn itself off than take out battery for 1minute
Put the battery back
Start the phone
discharge again till switch off
again 1 minute out
repeat till phone turn itsellf even when booting Winmo
Take battery again for 1minute out
put back batt and charge with phone turned off
when charged take battery out for 1 minute again
put battery back and start up the phone
i had this problem with my extended battery. I was curious so i opened it up and found it was two batteries stuck together.
pics here: http://forum.xda-developers.com/showthread.php?t=815231&highlight=extended+battery
I bought the official 2300mah extended battery with kickstand after reading problems with 3rd party extended batteries and the poor quality of back cover. I bought the official htc from ecell on eBay for £25.95 delivered - no problems. Somtimes it's worth paying the little extra for quality and the difference in price is not that big instead of wasting £10-15 on these 3rd party batteries...
Well maybe i will buy the official sometime but this one was fr 13USD so its bad luck but i can live with that restarting charge
it better to buy a oficial htc batery like i have one .with havy using its last about 40 h . so dont bay fake bateries.
But maybe i know how to fix it some one here at XDA talk ed about wiping battery stats maybe it will help

Here it is
I went into the T-Mobile store and asked the guys about the extended battery the other day and here's what the guy told me. The HTC official extended battery is basically two batteries in one package, just as jjbdoggg mentioned. When the charge runs out, if you power back up you'll have access to the 2nd battery. The thing is, they don't really instruct you on how to properly charge the extended battery.
When you first buy any cell phone battery, you want to charge it 100% before using it, some even say to charge it two to four hours over 100%. With the extended battery, you have to do this twice, first on the initial charge, then again on the second battery. Otherwise you will run into discharge issues like you've mentioned where the battery will drain faster than normal. I believe this is because the batteries have charge memory built in, but I'm not positive.
Anyway, make sure that if you do end up buying one of these batteries, HTC official or not, (I bought a $15.00USD one and it works just the same, just no kick stand... but it does have a nicer battery cover.) you need to charge both batteries like this:
1.) Charge 100% + 2-4 hours more if possible
2.) Drain battery completely to switch over to second battery
3.) Charge second battery 100% + 2-4 hours more if possible
4.) Drain battery completely
5.) Repeat steps 1-4 once more and your battery should function as expected

Thank you i will do it properly
get the original extended battery. also the 2300mah battery from the company "leicke" is working for me. i had a cheap 2400mah chinese battery before and had the same problem.
the thing is, that these chinese batterys are faking, they are normal ones because the driver of the hd2 origininally didnt support bigger batterys in the first roms.
the chinese batterys are out of date and also the capacity is mostly a giant fake!
my battery did cost 21 euro incl shipping and is working correctly.
dont try to fix the problem with hints and tricks or calibrations, it will NOT work with the cheap batterys! i already tested it
Well thats mazbe true but i have mz from china for 13USD i have calibrated it and now it stay 2 days then i pull out and put back the battery and i have another 1,5 day
What I suggested is not a trick, this is just how the manufacturers recommend you charge your batteries. If you don't want to follow instruction and do your own thing fine, but it sounds like jirka has solved his problem.

There is no second battery, it is a single battery with 2 cells, soldered together in parallel giving the higher capacity.
If your phone's charging firmware is not compatible then you need to update your ROM.
What you are doing with the above is charging the battery to 50% and then charging it to 100%

Do you own one of these or something? Because it doesn't sound like you have ever used one...
Yeah wafflefaust Thank you very much i have propperly charged it and its as i told up to 2 days on first part and 1-1.5day on 2nd part so Thank You

Yes I do own one.
I've also been making my own custom lithium batteries out of individual cells for over 5 years, I know battery technology.
I'm not sure if you've ever used the specific batteries we're talking about however. They do ACT like two separate batteries, but are packaged as one "extended" battery. When one runs out, you can usually pull the battery for about 5-10 seconds and when you put it back in, voila 100% battery left... (that is if you know how to properly charge a battery...)
Maybe you've figured out some sort of magic trick to make these batteries drain in parallel or serial? But the way it stands, the battery that I have does not act like you're suggesting.
So...I don't think this has been brought up here before, so I figure I'll be the dummy who asks. If I recalibrate (bump charge), and wipe battery stats, is it safe to assume that swapping out batteries (spares) will mess this up? I plan on picking up a spare battery, but wondered about this. Any input? Thanks in advance.
Not sure about the "bump" policy around here. but...........BUMP
Just charge the battery and use the phone. Don't get caught up in the whole wipe stats to create longer battery life craze.
I just swap batteries when needed about midday. I ignore the battery stats. They don't affect my use of the phone.

I understand that wiping stats does not "improve" battery life. but I have no problem believing that with a recalibrated battery (@ 100%), wiping stats will help the phone/battery meter "read" more correctly.

I thought so too, but I believe coupling it with a bump charge helped me a lot. I'll explain:
I recalibrated my battery about a week ago, (didn't know about wiping stats) I improved by about 3 or 4 hours daily, bringing me up to about 15 hours of use on a charge.
However,before I posted this thread, I did a recalibrate along with a wipe, then allowed the battery to drain and then a complete recharge. As of right now (27 1/2 hours later) I'm still looking at 30%
However, thats not why I started this thread though, I am simply wondering if swapping batteries back and forth will affect the stats and how the phone reads the state of the battery. (makes sense that it would I guess)
any input on THAT would be awesome, thanks in advance.
True. Unplugging the charger as soon as it shows 100% won't give you a full charge since it's not really accurate. I believe the charge complete notification is triggered by the charger shutting down. Not positive but I have noticed that can be triggered at varying times after 100% is reached.
Swapping batteries does mess it up but I can't say how much. There's always going to be a difference in charge between the two, and depending on different brands, a difference in the battery capacity and voltage at different % levels.
In short: The charge circuit measures amps going in and coming out, and remembers voltage levels at different times, so swapping batteries or using external chargers probably confuses it a bit.
Would it be possible to just create a separate batterystats file for the spare battery and swap out the files when the batteries get swapped out?
There was a post recently by a Google engineer, Dianne Hackborn (can't link yet, just google "Dianne Hackborn battery stats" and you should find it).
It explains that the battery stats come from data/system/batterystats.bin and are reset every time you unplug with a "relatively full charge." The file is reflected in the battery use screen.
It won't affect how much battery level is shown to you or how long your battery lasts.
Hello all,
I'm having a weird battery problem and am not sure if it is software or hardware. Basically, I have charged and it will last about halfway through the day. I'll look at it and between 50-55% of battery life it will turn off and go dead. I'll turn it back on and the battery is at 0% - no warning or anything. I have to then charge it back up and it seems to take a while from 0-25% and then it will skip to 90% and finish charging to a 100%. I've tried several different roms and all are giving me the same problem - currently on oxygen 2.3.7
How old is your battery, and is it a stock battery?
You may want to calibrate your battery. There is an app on the market that is specific for the N1 and instructions for it can be found http://forum.xda-developers.com/showpost.php?p=9583271&postcount=340
It isn't the easiest thing to do, but if you do have a decent battery (some cheaper knockoffs don't have support of figuring out your battery age), it can get your phone to properly detect your age of your battery and show the correct stats for it.
As for it dying half-way through the day... have you checked to see if apps are chewing up your battery time? If they aren't, it may be time to get a new battery anyway.

It is the stock battery I got when I got my phone in May of 2010, so I can expect to be not as a good as a new battery but it's bothering me that i can't have a an accurate reading on how much battery I have left. I feel like I have half a battery left and then all of the sudden it will die. I'll try the calibration and see what that does. I don't think its apps because I've flash and reflashed my phone and never have many apps as a result
Hi there. New here.
I have a Galaxy S I9000 running CM7.1.
Recently, I have bought one of these fat batteries from here:
dealextreme.com/p/3-7v-3500mah-high-capacity-battery-pack-with-back-cover-for-samsung-i9000-galaxy-s-54276
I did not have much expectations, but the reviews were pretty positive, so I went for it.
To my "surprise", the thing did not work much better than the original battery. Obviously I went around looking for what could be the issue (I did not give up on it just yet), and I found all sorts of data about "battery calibration" techniques and such.
I charged the thing to 100%, and used the "battery calibration" APP from the Market. Did a reboot, and took it for a spin (day of avg. usage). Nothing changed about the performance of the battery.
I gave up and returned the old battery. Re-did the calibration procedure from above ("just in case").
To my surprise, all these games apparently "damaged" the battery life of the original battery somehow!
I got down to 50% charge after 10hrs of *no usage* at all (The battery stats show 40% for "cell standby"). No CPU intensive processes were running during this time.
Now, it's obvious that the battery itself did not get damaged in any way. What this does show, however, is that this "calibration" procedure did have some unexpected "persistent" impact.
One thing for sure, is that I do not understand what actually happens during this "calibration" procedure. From what I read, it deletes some "battery stats" file that is later regenerated by the OS over time.
My questions are as follows:
1) Any one seen anything like this before?
2) Will the "life" of the original battery "improve" as time goes by (as the battery stats are collected), or am I screwed without doing something about it?
3) Is there still hope for the fat battery I bought? Seeing that there are significant "energy losses" dues to some software calibration issues.
4) Is there a "right" way for switching between batteries with different capacities?
4) Anyone can recommend some APP that shows better stats about the battery? For instance, a representation of the contents of this "battery stats" file? How many MAHs the battery "has"? Any kind of interesting "debug" data?
I'd really love to have my (battery) life back.
Thanks.
Bump.
Anyone?

1) You're running CM7 which is known to be a battery hog so dont expect phenomenal battery life with it. Also a lot of the aftermarket batteries are fakes with their actual mAH being even lesser than that of the original samsung battery the i9000 ships with. And the battery you bought costs $15 which is way too cheap for a 3500mAH battery which basically means the battery is a fake and you were ripped off.
2) After deleting the battery stats during the calibration process it takes a few charge-discharge cycles for the battery 'life' to improve. Give it a week to settle in.
3) there is no hope for the battery you bought, unless you can return it for a refund maybe? if you cant return it, you might want to take off the battery label and see the actual mAH of the fat battery (as this is sometimes printed on the plastic shell of the battery underneath the label).
4) When switching batteries you simply run the battery calibration after you've fully charged the new battery in your handset and then you drain it until the phone fails to boot. Then you charge it to 100% without turning the handset on
5) Battery Monitor Widget is an app you might want to take a look at but it does not have the exact battery capacity for each phone pre-fed into its databases since the battery capacities vary with the manufacturer and model of each handset. It relies on you entering the exact battery capacity from your battery label into the application before it can function properly.
Thanks for the response.
I'll do a few charge / discharge cycles, and see if it improves over the week.
Just for science, I peeled off the label of the fat battery and found no useful data there. Only some kind of S/N which did not show any results on Google.
Shame. I guess I'll just leave a negative review for the battery and be smart enough the next time.
Alright, so the biggest complain to this phone is the battery life as we all know. Trying everything to stabilize the battery life, i have used many apps but no luck. One thing I have noted after trying to fix the battery with a calibrator (root required), I read my phone using 4.1V. This is strange because for a simple Watt calculation, you do w= amps x voltage. If the battery can only manage 1.5 x 3.7 or 5.55 Watts and my phone specifically is taking about 1.5 x 4.1 or 6.15 Watts, this means faster battery drain.
What I want to know if there is some sort of voltage control app or modification to the power management for the phone to remain within the V3.7 specified by the battery.
I will also say that randomly my phone decided to run no more than V3.7 on Feb 14 and this is what happened. I unplugged at 7:22 a.m and by the time 9:30 a.m Came, I was at 70%, but then my phone lasted until 6:15 p.m or 18:15 after that. And noted that i did regular texts (sent and received about 200) had a 15 minute phone call and about 1 hour and 15 minutes of bluetooth music playback (I use Bluetooth headsets **Jaybird SB2**) and some internet usage. Not 12 hours but better than the 4 hours most of us get.
What are your thoughts as well?
Juice Defender and/or Gingerbread
I use both gingerbread 2.3.5 and juice defender, still no luck. Just going to buy 3 batteries.
I wiped my internal SD and factory reset my phone, that did wonders. If you have GB and Juice Defender and your still having poor battery life there must be a problem that hopefully should be fixed with a clean slate, unless you have unrealistic expectations out of your battery.
I'll try what you have done and then ill let you know. But my battery is crazy bad. how many hours do you get? the percent drop is insane. its a little frustrating because my mind is always on battery percentage and my eyes are stuck to the notification bar looking at the battery instead of "enjoying" the phone.
I charge my battery every day.
I'm running 20C with Andida's 1980mah battery.
how often do you use it during the day? i have read that andida's 1980 only gives an extra hour
I used to get 18 or more with froyo and juice defender. Now I get similar on GB without Juice Defender that's with mild use like calls, texts, web surf. As soon as I fire up a game especially 3D ones ill charge immediately after just to be safe.
I play GTA 3 about an hour-two every day,and my wi-fi is never off
I flashed the Lestatious Biohazard Kitchen Rom after flashing the GB 21a baseband and my battery life is better than it's ever been.
buy a better battery
i brought an hyperion battery from ebay.... sure the battery is a little over double the thickness of a typical battery (it comes with a new back cover too) but the life of it is amazing!! i now can leave the phone (fully charged) for 6-8 hours while sleeping and wake up with the phone @ 97% and that's on the default rom.... best $18 ever spent
