Hello there!
2 weeks ago I have replaced my Dynapack 1350 mAh battery with a 2800 mAh one for my Tilt 8925. Everything is great just that the phone does not recognize the new battery which means that it shows the same lifetime of the battery as being short as the previous one.
Everytime I'm getting the low battery message I have to shut off the phone, remove and plug the battery back and the battery shows 50-70% battery so I get 1-2 more days to fool around with it.
My question is: is there any tweak/software that can be installed in order to keep monitored the battery according to its actual lifetime? Or should I start making a habbit of unpluggin/plugging the battery?
Thanks in advance!
Any ideas?
Bad phone?
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.

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.
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.
Hey guys, its my first post on this forum (or on any forum for that matter) so I apologize if this is in the wrong section . But recently I've been having a problem with my S3 mini and hoped I could get some help on here. So a few days ago I got a 4000mAh - 3.7V extended battery for my phone because my old one had broken. The old battery was the stock battery that came with the phone. Before I bought the new battery I also installed the PacmanROM on my android. But since I got the battery the percentage my android displays has been completely wrong. I'm pretty sure that the battery is fully charged after over 16 hours of charging but the percentage the phone displays is only around 65% and no matter how long I charge it the percentage never reaches 100 and it will stay on a certain value that will randomly fluctuate if I restart the device. So is there anyway to make my phone display the correct percentage? Thanks for your help!
In my opinion, extended batteries are more trouble than they're worth. I have dabbled with them but all have failed at some point (even brand new). If you put the battery on a flat surface and it 'wobbles' at all then its duff. I use stock batteries. Sorry if this is not what you want as an answer but just my experience with extended batteries.

Thanks for the input anyway! I've never tried any other extended batteries so I ignorantly decided to get one hoping it would work well. But anyways I believe that its not the battery that's at fault since the battery seems fine to me (no bumps showing a faulty battery). I have a feeling that its my old battery that's at fault or the system still possibly assuming its a stock battery. Well I'm no expert .
Awfully I can post the link for fix this..
The APP for fix this 'bug' is "Battery Calibration", it delets a battery file, and after restart the cellphone, that file is remade with correct data.
Well I looked into Battery Calibration and have managed to find a fix! I charged my phone to "full" (which my phone only displayed as ~50% at the time) and once the battery percentage stopped increasing I left the phone to charge for a few hours after that. Then when I was sure that the battery is actually full, I installed a battery calibration app and "calibrated" my battery which deleted the batterystats.bin file. I then waited for my phone to completely run out of charge, which I sped up with an app called "battery discharge", then when I let the phone switch off by itself from an empty battery. Once the phone restarted the battery percentage displayed was correct.
Try Battery calibration
isnt battery callibration a complete myth and placebo? deleting batterystats.bin shouldnt help as it just contains data about what consumed battery juice
