hey is there a tool or software with which i can check if my battery is broken or if it has full capacity? my battery lasts only 2 days, this sucks!
if i use a 1600 mah battery, will the percentage be displayed correctly? or can the tytn only handle 1350 battery and i have to take the 1600 out and put it back in?

two days is not bad. mine wouldnt last more than 24 hours due to the way is use it. i have bluetooth on all the time, wifi on nearly all day and my display is set to the brightest mode and i turn it on very often. i dont expect the battery to last longer than 24 hours.
its a agood habit to keep pumping electricity into it every now and then
Yeah, I need to charge every night. It's not the battery per se, it's just the Tilt/Kaiser uses a lot of power, especially if you check email often, use BT and wifi a lot (GPS too eats up power). I don't use push mail at all, so that helps stretch the battery (I just manually check my mail periodically throughout the day).
I think many people would say if you are getting 2 days on a full charge, that is great!
Personally, I just got a second charger for my desk at work, and have a car charger in the glove box. If I know I'm going to be away from those for a lengthy period (weekends say) I have a AA battery powered emergency charger (from pocketsolutions.com) I can take with me.
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.
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.
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 ,

yep i agree, the original HTC batteries seem to be worst than the cheap aftermarket versions
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.
Sent from my GT-I8190N running CandyKat
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
