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
http://forum.xda-developers.com/showthread.php?t=827355
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%

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.

Ok so this is what i noticed has been happening with my phone...
I wake up in the morning and i unplug my phone from charger at 100% battery life...
after about 1-2 hours of no use (outside of occasional check of time) and no programs running i notice that 25% of life has diminished...
i have turned 3g off and done most of the kaiser tweak settings that help with battery life. for the rest of teh day i can use the phone and battery life runs normally but it seems the first 25 to 30% drops real fast without use
is everyone experiencing this? is it normal?
KP
The problem lies in your first sentence. "I wake up in the morning and unplug my battery." You are charging your battery too much thus killing it's battery life. I only charge my phone in the day while I'm at work. That way I can unhook it when it's fully charge. I would go on ebay and type in OEM battery Kaiser. You can pick one up for 15-30 dollars new.
From what I understand. Leaving your battery in the charger when it is fully charged should not damage the battery as long as its not there for an excessive amount of time but i might be wrong. Either way i have no way of charging the phone during the day as im on the go most of the time so this would mean even if i get a new battery it wont matter because it wile eventually do the same as i have only used this phone for about 3 or 4 months now. any other possibilities or solutions?
or should i just take it as it is and just buy a new battery maybe a bigger seido?
I thought Lithium ion batteries have overcharge protection. I charge mine overnight which I am sure a lot of others do also with no negative effects.

I do... Maybe I shouldn't?
I would hope it has Overcharge Protection!!!
With NiCad Batteries if you overcharged them you would kill the life of the batteries.
And while all batteries do this LiIon are least tolerant. If you overcharge a LiIon battery, that is without Overcharge protection, the LiIon Battery with BURST INTO FLAMES! Thus the problem with the Sony Batteries that caused all those Laptop battery recalls.

Thats total BS with lithium batteries.
To the OP: Try running down your battery completely once, until the phone switches off by itself, then recharge fully. If you never do it and always recharge before the battery is empty the battery's power meter can lose its calibration over time and display weird things.
If it doesn't help, and you can notice a drop in overall life time you might need a new battery.
I have the exact same "problem" with my Tytn II.
Is slows down evenly though. (So the first 5 % of battery vanishes in minutes basically while the last 5 % can last for an hour, when it's half full % will last somehwere in between these two extremes).
Personally I've just interpreted this as poor measuring done by the hardware and/or software. (Ie I don't think the battery performs better the less full it gets as the meter in Windows would have me think)

may seem a daft point but after draining the battery, dont charge with the phone turned back on. gives a fuller charge cos its not being used and makes it quicker to charge, lol

Hmm...I don't see how turning my phone off to charge would increase the charging rate dramatically. My phone in standby mode uses 1% every 2 hours.
depends highly on roms and especially on radios.
with a crappy rom, battery could drop as fast as 10% per hour.
with a decent rom, battery drops in standby mode at a rate about 2% per hour.

If the phone is on but on standby that barely changes a thing. If it's on, with display illuminated then yes it might take you an extra 20 minutes to charge.. no big deal either.
*UPDATE*
ok so i drained my battery last night completely(turned on navizon, tt7, and skyfire) which took me about at most 2 hours.
Put it in for a charge
woke up at 9 and checked to see and it was 100%
I have push mail set to update every hour and i also run pocket sportscenter autoupdates which updates every 10 to 15 minutes
I used the phone for 5 minutes of calls
5 minutes of web surfing
a few text messages
and the occasional time check
at 6:30 pm battery life was at an amazing 90%
i was thrilled.
i continued to surf the web heavily from 730 to 8
a few more text messages
at 9 battery was at 67%
so i gotta believe that draining the battery helped recalibrate it...
i guess every 2 or 3 months i got to drain it out and give a full charge
thanks for the help guys
really appreciate it
I know those Pocket PC devices drain their power very very quickly, but when I wifi for let's say about 5 minutes on some websites, my power is drained like 10 percent maybe. Is that extreme or 'normal' for the kaiser?
On the other hand I must admit that when I do nothing with my kaiser it can last very long without recharching.
Which rom and radio are you using? These devices are not exactly renowned for their great battery life (the cost of 3g and hsdpa), but there are ways to optimize them...
PDACORNERultimate. But I also used a HTC P4350 earlier, and it was all the same with the battery life , just wondering how I can measure what battery is better because I have 2 tytnII's until tonight, so I was wondering how I can measure what the best one is .
ALL batteries lose the ability to keep a charge as they get older. Any battery over a year old should be highly suspect.
Get the Tytn II that appears newer, then get a BRAND NEW battery for it

A new battery cured my fast discharge problem. At the time Amazon had the best price on batteries.
I've observed with my TyTnII (1yr old) that the battery drains faster from 100% to 70%. However, it retains charge from 70% to 0% for a longer time.

A 10% change on the meter means nothing. To evaluate your battery life/drain, start with a fully charged battery and run it down completely until the PDA switches off.
As said above, the percentage reading is approximate and won't always go down in a linear way. It can go down from 100% to 30% in one hour, then take 3 more to go down to 0.
I think you are using the wrong charger. The charger u are using is nog strong enough. I had the same problem. You need the original charger.
Lately, I noticed that when charging my tilt with the charger, it takes forever to get to 65% and then in almost no time, jumps to 100%. Is that normal? Does something need to be done? Do I need a new battery? If so, what's recommended?
Separately, when using WIFI, it uses over 400 mA -- that's outrageous.. Any way of improving that, while still being able to stream audio (ie power saving settings may be an issue)?
What's a good battery meter to help debug things?
Thanks
I have the exact same deal going on with my battery charge. Started happening not too long ago. With the stock ROM and with hyperdragon III ROM, I always see the jump.
I'm not sure what the problem is but I figured it was a false charge in that the battery's capacity has really lowered from the original 1300mAh. Also, thus why your batter drains much faster than it does (so does mine). If anything, it's probably just a normal battery problem which could probably be solved if you got a new battery. I haven't tried (yet). The battery life went from 3 day's of casual use with some data connecting here and there, to 1 day and if im lucky, a day and a half.
Hope this helps out a little. And if anyone has the real solution, do tell. Thanks.
Regards,
K
I had the same problems. Took forever to charge. Battery life was horrible. Could only make a 3 minute phone call on a 100% charge before the phone would shut off. Ended up being the OEM battery was done. Lasted about 1 year on heavy use. Bout a battery/cradle charger from Amazon that came with an extra battery. Also bought another 1600mah battery. Both of them work great. No more charging problems.

I too think it's a faulty battery (which may still be covered under warranty). It's always a good idea with the TyTN II to have at least one spare battery for long trips etc (I have the original and 2 spares as well as a cradle which recharges spare batteries). The O/P should try another battery to confirm that works normally and if so and the original battery is still under warranty, contact HTC/The supplier to see what can be done. IF they need the phone (and I've never tried claiming on a battery under warranty), make sure it is fully reverted to 'as from the factory' status using all official ROM/Radio/SPL before sending it in.
Edit: The o/p could also try cleaning the battery terminals (using a cotton bud soaked in contact cleaner) to make sure high electrical resistance has got nothing to do with it.
My battery never charges above ~76% when plugged in. After rebooting however, it is very much at 100% and lasts for a good amount of time. This is not necessarily a question, but I wonder if others are experiencing this too and if there is a fix? Read below.
I noticed that my battery life got very bad after installing custom roms. I also found out that this happened because I sometimes kept the phone plugged in while flashing, something that totally screws up the battery reading. So, I followed this guide to calibrate my battery and it worked.
Now, whenever the phone is plugged in it NEVER goes to 100% when charging. Maybe 80% if leaving it for a while (10 hours overnight). I'm worried about frying the battery. Is there a fix?
It is only a matter of presentation. It actually doesn't mean your batt is broken. Plug it and charge it overnight. Then discharge only for few percent and plug it back in. It should go to 100%.

Thanks, I'll give it a try.
What I'm concerned about is if the phone "thinks" the battery isn't recharged and keeps squeezing juice into it when in fact it is full (which a reboot will show)? That's not good for the battery. It should go into trickle charge after reaching 100%..
The process described in the desire forum is also known as formatting the battery. In fact most of battery manufacturers (lithium battery manufacturers) recommend doing this in a slightly different way:
Before first use:
1.) Before powering the device on, plug it in and let it charge until the LED is green (fully charged)
2.) Then take the battery out of the device and wait an hour (to make sure all the chemical processes in the battery are as idle as possible)
3.) Then plug it back in, while still off and let it charge untill green LED
4.) use the device....
You can practice this slightly modified with first step being:
Discharge the battery (by normal use)until only few percent are left (1 - 5 % are OK)
I've done these steps with my Mugen extended battery and I was getting around 4 - 5 days on Legend, now I'm getting 2 - 3 days on Desire S, but the ROM isn't very optimized yet, I believe it will be better in time...
Just one thing... Why is this in Development!?
No Idea.....
can mods move this?

Definitely did not solve it but at least the battery performance is ok. It just stays at 78% for a few hours drops from there. Very weird but as long as the battery doesn't get broken I guess it's ok.
Do you have some 3rd party battery installed in your Legend? I have one 1,5 Ah in mine and it is acting the same way. It doesn't bother me too much coz it was cheap... it lasts 48 hrs with data always on and moderate usage. I noticed this that when I charge it overnight and it reaches 80%, unplugging it stays at 80% for several hrs and just after it starts dropping if I plug it again, meter reaches 100%. It's weird but as I said I can live with that
I've got exactly the same issue with stock 2.2 ROM. I've never rooted or CM my phone; I was wondering if CM would do it, but doesn't look like it.
android forums /htc-legend/265545-battery-doesnt-fully-charge.html
(sorry, I can't post links; maybe an admin can fix the link for me?
This seems to indicate it's a phone hardware fault and requires a new Legend to fix! My big worry is, as stated, that the charging light never goes green; therefore is pumping lots of power into a potentially full battery.
Recently I bought a cheap battery which is obviously from china.
And it looks like the original HTC battery with the same black colour.
On first use it came with 80% charge level . I used the battery until it drained . It lasted the same as my original worn out battery of 6 months at the same percentage (maybe due to old batt stats in the is)
the following charge cycles( full drain and full charge)
First full charge cycle -battery only charged to 72%.
2nd cycle - battery charged to 75%
3rd cycle -battery charged to 83%.
one of the major difference is that with this battery,the phone shows that red juice cylinder , when it starts charging from 0%. Something I didn't saw with the original HTC battery after mango beta .
The first 2 cycles the battery exhibited the rapid drain symptom after plugging off the charger .
after the 3rd cycle it does not have this behavior and drained normally.
After this 3rd cycle the battery indicator was stuck at 80%. Used the phone for 3g browsing for 30 mins . Restarted the phone and it showed 91%. Used till 77% and charged the phone to 100%
At this time the battery is doing great . Will do another cycle a few days later to see how it goes.
In between these charges I had some small partial charges.
So far the battery now holds better and able to surf continuously on 3g for 40 mins and its at 90%, WiFi off , location on ,bt off ,battery saver on ,
the funny thing is that it is like the same quality original HTC battery .
is is mango with latest firmware update.
there are some problems with the original HD7 HTC battery.
mine did not last long before it died.
HTC needs to do QA on its batterires. They are the worst ever used
I recently (two days ago?) had a big 3500mAh battery arrive which i ordered from the internet, i paid about £14 for it. I've noticed it's a little weird in terms of performance, and i'm not sure if that's anything to do with the HD7 software side, or if i've just been ripped off.
3500mAh is ~3x the capacity of the stock HD7 battery so i was expecting charging times to be way, way longer but also for my phone to last a good deal longer too, but i've just been seeing major inconsistencies. My new battery would charge and discharge faster than the stock one that came with my phone, it'd stick on 99% charging, it's really confusing.
At the moment, it seems to be behaving itself with 56% time since last charge 15 hours, time remaining 9 hours. I have reason to suspect that when you use a new battery that the battery information Windows Phone 7/7.5 provides is WILDLY inaccurate, and it might take some time for the software to get used to the new battery.
I'm not sure, i'm just finding batteries really confusing!

try using a custom rom, the battery usualy lasts longer. the sdcard tweak works well . i beleive its a prblem with how wp7 OS handles the sdcard power management
i beleive the OS uses power consumption vs power capacity to judge the gauge. also u whenever u full charge the battery , u need to let it rest for a few hours. so ideally every evening u get home, charge it to 100 % from whatever is left with and unplug from the charger immediately after full. leaving it ont he charger whole night seems to drain it when u take it out fromt he charger next morning and start using it.
try using this app battery discharger ( free ) from the marketplace: it calibrated my battery well
when its close to dying like 20%, just run this app , and fully drained, charge full again
now my battery last 30+ hours on idle. i am not sure if yr 15 hours is correct on that size u have ,
