Kaiser battery drain

Seen a lot of posts about battery but no real solution, still wandering if following normal ... I bought my Kaiser 1 month ago, had trouble with device, like some other here, when Kaiser just went dead, get it to service and back and now is working smoothly, but with a "small" problem.
Having battery charged full to 100%, after 3 hours of work on battery inclusive of 58 minutes talk it is down on 73% power only. Checked all posts but have not managed to figure out if it is normal. Taking information from booklet, should have available 420 minutes of talk time on GSM settings.
(according to my math after 3 hours of described usage, should have used 14-15% not almost 30%)
CHECKED ALL, NO BLUETOOTH ON, NO WIFI ON, NO G3, to the best of my knowledge, all battery eaters are off.
Any advice on settings...or back to service...which is bad solution as last time they returned it to me with wrong gsm setting and I have had to use net to ,find solution.
Thanks in advance

It's normal. For god's sake, what do you expect? A Nokia?
Suggestion: put the screen off while talking.

Nokia, whats that

Kaiser gets hot (warm) after use for a long time

Hi amigos:
I been searching around and I cant find a solution for this annoying thing .
If I connect to my 3G usign my kaiser for more than 10 minutes, the phone is getting extremly warm. I try to put the back light low but doesnt help. I'm usign Dutty 29 apr. Rom and radio version is 1.58.21.23 and I'm in Denmark.

Is your battery draining fast?
Get a battery meter and test that because I had a TyTN that did that...

same here original rom wm6.1 NL

If I where you I would try a diffrent radio and check what aps you are running in background/prosseses. I often use my kaiser as an wifi router and I dont think you gets close to as warm as mine streaming and charging at the same time I abuse it so hard it resets itself, now thats hot hehe. Anyway, some radio are battery monsters for me, its just about to find the best one for youreself.
I have good experience with: 1.58.25.17 in Norway, havent tried it whit duttys.
If not you can try 1.65.14.06 and 1.65.17.10 wich dutty included whit the release.

To 2007HHR: Yes the baterry draining fast that is the worst part. what is the purpose for use a battery meter? Its going to solve my battery problem?
Raiisak I will try another radio, hope it will help me, I never experience a phone that will become warm after using it for a long time. Really annoying

i only experienced this one time when i had my gps turned on for half an hour and my phone turned into a hot potato and battery went from 95 to 15 percent.
u have to realize though that the tilt is sorta like a mini laptop and it will start getting warm after some time unless u give it some rest.

Well I never experience something like it in a windows mobile before, I will be really interesting to know if this is a hardware failure. Have you guys experience something like this in other htc phones?

Unfortunately this is almost unavoidable with lithium batteries. My HTC TyTN II battery gets hot while charging, and even hotter if phone is being used (voice or data). It gets hot to the point that the battery stops charging (at least they have thermal control circuits, it could explode otherwise, lithium batteries do not like the heat).
The same happened with my previous phone, from e-ten. A battery got very hot and damaged while talking for a long time. I have used my devices mostly as a PDA, for reading or playing music, but as soon as phone radio is on, it starts getting very hot.

Hi Vcespon:
THis is horrible, I can't belive with a advance phone like kaiser something like this happen. Is there any firmware that might fix this, otherwise I will thinking to change this phone, this is unacceptable.

That's not normal. If it is the case your most likely have a hardware problem. Same to the OP.
Mine also got warm and was emptying the battery in a couple of hours once the radio broke down.
Other than this, the only cases where the phone will get really hot is when using WMWifirouter to route the 3G connection to WLAN and downloading a lot. Both the 3G and WiFi radios being on and working hard, plus the processor doing the routing uses a tremendous amount of power. But the device wasn't meant to be used that way anyway.
The GPS also uses quite a bit of power so if you have that on on you might want to try turning it off.
When just talking on the phone the device should get a little warm but no more.

The battery meter would show how much of your battery is being drained when idle... mainly shut down all applications and see what the reading is and that would give you an idea if the device is defective.

I can tell ya, mine gets HOT. I sent the first one back because I thought it was defective. Also with a couple different roms it makes no difference. If your using 3G, BT, GPS, or any combination of those, that SOB will get hot. If I'm charging at the same time, it gets so hot it shuts the charging proccess down. I have to hold it over a AC vent to cool it back down.
Over all though, the only complaint I have with the phone is the heat and battery drain issue.

dead phone or dead battery
Do not know if this where to post. But my TyTn stopped charging. The phone is completly dead. Right now I'm on vacation in a remote location with out any access to the local AT&T to get a battery quick. But the problem is that the battery is not taking a charge. The red charge light is not on or anything. I left the phone on the charger for two days and nights with no results. I ordered a battery but will not have it untill I get home in another week. I have Dutty's 6.1 5.2.19199 UC Compliant ROM on the phone and I've been using it for about 10 days now. Everything was working fine. The phone was getting warm during GPS useage and when charging. Right now I hope that its just the battery. But in case its not, I need to know what my options are. Is the phone dead? What other measures are there to bring it back to life? Thanks in advance.

I can say from my experience with a tytn and now a tytnII when you use them rigorously , they will get hot. I guess the real question is how hot is it really getting and what is running on the phone. Is it uncomfortable to hold?

On EDGE data with FlexMail and IM+ online, the phone stays ice cold. On HSDPA the same, it gets slightly warm. When talking on the phone with HSDPA, it gets a bit warmer.
When using GPS+iGO8 or TomTom, it gets rather warm. Add charging and it gets pretty hot. I've seen batterystatus show as high as 42C using internal GPS+iGO8+Charging.

Gets hot + doesn't charge from laptop
I've got a similar problem - Kaiser may get hot when being used as a modem and/or charging...., well I've actually had this going on from time to time and wasn't much concerned about it until now: the battery doesn't charge when connected to my laptop - ActiveSync or modem, the amber light doesn't come on, plus drains fast.
The Kaiser(so the battery) is only 3 mths old (although I use it heavily as a modem) and I guess it's unlikely that changing the battery will help here...

My kaiser gets warm too.. I guess it's because I'm hot.

Never mind
HR fixed it...

You also have to remember that these things have a 400mhz processor in them without any fan. Now when your using that processor to the fullest, it IS going to get warm. This is what your going to get from any high performance electronic item without a cooling fan. It's not unacceptable, it's the way it is. 3G, bluetooth, and WiFi can be very processor intensive depending on use, imagine all 3 on at the same time, not to mention the added heat from rapid battery discharge (which is unavoidable when using the radio).
The designers of the phone are no idiots, they designed systems that shut the phone off if it's going to get damaged. So if your worried about the heat cause it's uncomfortable, don't work the sucker so hard! ;-)

Hi to all and thanks for the replies;
My theory is that if you buy an expensive phone you need to exploit until the limit. I bought the kaiser because is a phone that can give me almost any kind of connection and I can be connect online almost everywhere. I can't stand that If I use the 3G connection for 10 minutes the phones gets so warm. I use battery status too and the temperature is like 42F after I use the phone for 10 minutes.

Battery life issue

OK,, I am not any kind of expert, I do good just to get me email working on this Tilt. But lately I have had very little battery life out of my Tilt which is now about 60 days old. I charge the phone every morning before I leave, and here it is, 1:30 pm and I have one bar of juice left. And before 5 pm, it will die of battery loss. the screen is not staying on all day, nor any other obvious drain on the battery.
Any one have any ideas??
Still on WM 6.0
Thanks

well check if your email is set to download complete email with attachments or only headers / upto a certain limit. Setting the email to download completely can drain up the battery especially if you have a lot of attachments downloading with it. Also heavy usage of the vibrate function can drain your battery pretty quickly

What radio are you running? I had the same problem until i tried a few different radios and settled on 1.58.25.17 . Make sure you check the ultimate radio thread for which roms support which radios.

Thank you both,,
On the email,, it is set to just download headers,, I have it checking three accounts, I am sure that helps drain it a bit, but seems like it should not be draining in an afternoon, and with little use I might add.
On the radio I am currently using 1.27.14.09. ,, does anyone have a BRIEF laymans description to the radio, is it just the"driver,or program used to run the radio? I am sure though that I can find how to change it in the forums.

try this Ultimate Radio Thread
also read up on the subject in the wiki. Updating a radio is quite similar to flashing your phone..if you dont know how then i suggest you goto the wiki and read up on it...
Cheers and all the best

Another Great Trick is if you are having it check email. Find KaiserTweak or Schap's AdvancedConfig and Find the Setting to Disconnect 3G connection after 2 minutes.
The Email Connects to your 3G connection and leaves it on all the time. 3G Sucks Battery. Using these tools to have it turn off after 2 minutes allows you to get mail and not loose a lot of battery power.

If you get really stuck then a nice rechargable external battery (like the one from Proporta) is nice to slide in your jacket pocket...

My problem also
Originally purchased my Tilt from New Egg. Special $179 w/$50 rebate from AT&T. Battery life was moderate. I have been a user of Pocket PCs' for a long time before buying a converged device, PDA Phone. Windows Mobile PDA platform uses a lot of battery, period.
When I say battery life moderate, I mean that, I could not get through an entire day with average usage without a recharge.
Recently my phone experienced a failure which required a warranty exchange.
The phone was replaced with a refurb unit from AT&T warranty service. The battery life was horrid. Normal usage for me is. Bluetooth running, two email accounts downloading every hour, weather bug mobile updating 30min and 1hr for various settings, occasional phone calls, web surfing (moderate) email reading, downloading attachments as needed, etc.
The phone replacement (warranty exchange) was experiencing, long charge times, inaccurate battery charge values (68% battery charge, upon reset 89%). Quick discharge (100% upon initiating call using bluetooth, 75% charge after 15 min.).
Returned phone to AT&T warranty service, had battery replaced with new! battery ( I say new because the battery I received with replacement had a dent on the metal part on back)
Fully recharged new battery, made a few calls. O.K.
Set WIFI on. Set GPS on. Set Bluetooth on. Surfed the web. used Resco Explorer to move files from computer to PDA/Phone. After one hour battery level is 91%.
My belief is that HTC ships defective product. I have read multiple threads about users having multiple problems, and users having no problem at all. Hmmm.

Hmm..
Afer two hours 90% battery

Hmm..
After two hours 90% battery

JimmyMcGee,
One question on those,, I tried to install the Schap's advanced config, I put it on my SD card and tried to install it from there, the phone rejects it saying on of the MS drivers or something was out of date,, any typical problems that need fixed, or should I just try the Kaiser Tweaks?
Thanks,,

After 1.5 hour, battery 89%

All you geniuses
Before I post I may put on my flame retardant suit, NOMEX on. OK.
We keep looking for software repairs of these issues. These issues are hardware first and firmware second. Consider the source, which manufactured dog food. Some dogs died. Consider the source, which manufactured tires for cars. Some people died. Consider the Source, some Kaisers died. We can flash radios, OS's all day long. If the equipment has hardware problems. What is to be gained?

Two Hours
Two hours.
WIFI on. Bluetooth on. GPS on. 88% battery.

My point is
That all these tweaks may improve marginally a variably produced product.
The issue is that quality control and product management was lacking at the source. These things are pieces and parts. For the Original Poster.
I know you are a newbie. These folks consider me a newbie also, though I have been involved with product support and maintenance for more than 35 years. Take your device to an AT&T warranty service center. First ask for a replacement of device and battery.
After several hours 87% battery.

Battery Life

Hi Guys
I work in the IT dept of my company and ive got the job of supporting all our WM devices. (97% of them are the HTC Tytn II/Kaiser)
i get moaned at alot about this things and the main thing is the battery life is p*ss poor! All they run is active sync to pull in emails as they arrive and then the usual phone call, but yet the battery still wont last a day.
Does anyone know of any tricks or tweaks i can do on the devices to make them squeeze out every last drop of battery life?
cheers

Yeah, if you can get Advanced Config installed on their phones, fire it up, go to the right soft-key "Menu" option, and in there should be a Comm Manager selection. Pick it, and in the panel that comes up check on teh 3G button. Then, close out of Advanced Config and let it reset the phone. When the phone comes back up, go into the Comm Manager and there will be a new button to turn 3G on and off. Turn it off. If all they're doing is phone calls and pulling down emails, the Edge connection should be more than sufficient. I've also noticed improved battery life by leaving bluetooth turned on all the time (I now it's counterintuitive and could be a placebo effect, but I swear it makes a difference for me.) I can get well over 2 days on Edge connection with the stock battery using these 2 tricks.

If they don't have them already, you may want to have car chargers installed in the company cars of those with TyTN IIs. As for settings yes disabling HSDPA or even better going back to just plain GSM rather than 3G will help battery life (although also slow down any internet connectivity). You could also try turning down the screen brightness as this has a major effect on battery life but then they'll probably all complain the device has p*ss poor screen visibility (especially in bright sunshine - so if you're in the UK this won't be an issue )
If these suggestions don't work then I think the best plan will be to make it as easy as possible for them to top up charge during the day, perhaps with desktop cradles as well if this would encourage charging. I sometimes need more than one battery charge in more than a day (I've even used up all of my spare battery charge as well on a day involving lots of GPS navigation on foot) so yes these things do normally use lots of battery power if you have all the bells and whistles running and no charging occuring. Make sure wifi is left off on the TyTN IIs unless it's actively being used at the time.
Which ROMs are they using - all HTC official? There are reported differences in battery consumption depending on the ROM version used.

cheers for that guys
I will give both of your suggestions ago, next time i get one of the tytns in front of me.
I have the advanced config for the HTC diamond would that work on the tytn? if not where would i get that from?

Is it just me or are we being left with the sour taste of "Why should we have to compromise on the performance of the device to get 2 days battery life out of it?"

Unfortunately " push " email kills an already suspect battery. Activesync and your media net ?, edge? or 3G remains connected all the time . I had to go from " when they arrive" to " check every 30 minutes " for email or else my battery , even with minimal use would not last past 5pm.
I really miss my Blakberry in this respect. My Tilt does everything and everything for me, and does so on battery power. I guess if it just made phone calls the battery would last for days.

i agree denco, all the HTC WM devices ive ever had, they've had a load of functions but the battery is all very weak! whether or not that is something to do with HTC or WM i dont know, but its very annoying and just something we have to live with as my company signed a 2 year contract with Orange in March so there is nothing we can do!

Well, I doubt that it is Windows Mobile; ok, to be correct: WM has gotten more powerful with each new version, got even more and more graphical additions, just like Vista compared to XP. For sure this needs much more horse power and, in fact, processor and RAM are increasing. However, HTC barely increases battery capacy as well - might it be because of size / weight proportion or other reasons - I don't know!
I had the MWg Zinc II for a while and the battery life (1500mAh capacy) was amazing. However, audio / network reception quality was a joke on that thing.
Thankfully, there are HIGH CAPACY and EXTENDED BATTERIES available for the HTC's. They make your device look funny but surely increase your battery life as well.
I am (still) willing to sacrifice battery life for quality; arranging my life by having a car charger and also a 2nd battery with me when on the go. Hopefully HTC's batteries will evolve and have higher capacy in future devices.

Kaiser battery life
I am not an expert at this. I also was unable to keep a battery operational for half a day until I did a hard reset, and brought it back to stock ATT 6.1. Then used the phone without email for a day and noted no excessive battery drain. (70% at end of the day) Kaiser tweak added, with the “Disconnect after” parameter in the Data (GPRS/EDGE/HSDPA/WIFI) set to 1 min. Added the MS Push to my Exchange server, and only use the single email account. No appreciable battery drain. (68% at end of day)
The only thing I have NOT enabled yet is the ATT Navigator. Will add Google Maps and see if it messes with GPS chip. I have read and experienced the GPS draining my battery, even after turning it off, within a couple of hours.

In the advanced config, there are also settings for "Power management", make sure there is enabled in all of them.

Nah, considering the EEEpc I have gets about 2 hours battery max, and I can do a stack load more on the TyTnII than on the laptop, I', pretty happy. I had aan old Nokia that would go for 2 weeks without charging, but for a high end, gps enabled windows phone, 2 days is amazing.
@ splash08 : you can also try upgrading to the new 1.70 radio found in the kaiser rom thread, seems to give me less drain. Also, you can buy larger capacity 3rd party batteries.. maybe thats the best soultion.

GPS (Telenav) causing my battery drain
Since my last post on the 27th, I have had ZERO problems until I used the Telenav on Friday evening the 5th. Since then can only get about 4 hours out of the battery before it drains completly and that is with ZERO use. I have uninstalled Telenav and done multiple power down, but stilll draining. Looking for a way to turn off the GPS before I do a hard reset.
GPS had no issues with google maps and no battery problems.

ive now tried all those suggestions but non have really made a dramatic increase. I thought i cracked it at one point, over a weekend my phone last from saturday all the way though to monday night! but then i realised that saturday and sunday is off peak so the push/pull function was set to every 60mins! As soon as i got back to work during the week the device would last just over one day, on emails only.
i think i may have to look into getting the extended batteries or maybe changing all the devices for a none HTC device, as they seem to have a weak batteries (but i think this may be the last resort at it will cost a lot ot change all the devices)

Urgent problem: kaiser turns off on wifi and phone calls

Hi there!
I recently changed my battery with an ORIGINAL new one because I had a problem... that is still here...
Every time I turn on wifi (even with 100% of battery) my phone turns off after 2 or 3 minutes (and it seems that's because of the battery.)
Sometimes it turns off even when I'm just calling (more often when the battery is less then 20-30%).
EDITED: 30-40 seconds before it turns off the screen and the physical keyboard backlight start to flicker.
EDITED: Now it turns off EVERY time I make or receive a call after 4-5 minutes!
Exemple: Today the battery life was around 50%. I tried to turn on wifi. After 2 minutes of wifi use it turned off. I tried to turn it on but there was the flashing red led and it turned off again every time (it was like uncharged ).
Then I tried to remove the battery for a few hours, I put it back in and the battery life was the same of before the "turning off" problem, around 50%. What does it mean??​
My hypothesis is that it gets excessively hot when I use wifi and even when I call... But I don't really know what that's about..
[my ROM is this: http://forum.xda-developers.com/showthread.php?t=586463, the english version. I got the right RADIO, I checked yesterday]​
Thanks for any suggestion!!
Fabrizio
[sorry 4 bad English]

Try this...
Check the battery contacts on the phone -- clean them with a little isopropyl alcohol, and gently pry them up a little so they make solid contact with the battery.

I'll try what you say, thanks a lot!
I just want to say (I forgot it in the first post) that the screen and even the physical keyboard backlight start to flicker 30-40 seconds before the kaiser turns off.

After prying and cleaning the battery contacts the problem isn't solved yet. I didn't use the isopropyl alcohol, I'll try it asap.
Anyway now the problem is even worse, the kaiser shuts down each call after 2 or 3 minutes! Of course if the phone is charging (via usb) NO PROBEL, even the flickering isn't there any more...
Any other possibility of fixing that? (I have no warrantee, I really hope I fix that by my self just with your help!)

btry prob
well.. find out if one of ur friends has kaiser..... exchange batteries... i.e u isert his btry into ur kaiser and ur btry in his kaiser and then try the wifi n calls from both fones..... this will precisely tel u whether it a fault in the fon or u didnt get The genuine btry.... hope this helps.... do leme knw.....

Thanks for replying but I'm using a brand new battery and the problem is still the same of the old battery, nothing changed...

perhaps the problem is really not the battery but rather the battery's charging.
the point of exchanging your battery with a friend's battery is that you will be able to test your device with a known properly charged battery.
alternatively, you can try to charge your existing battery with an external battery charging pack or by inserting your battery in a friend's phone and let it charge there.
i understand that you claim your battery is brand new, and this is leading you to conclude that it can NOT be the battery at fault...but strange things happen in this strange world!

Wow I didn't see this problem from that point of view!
The only person I know that has a Kaiser is 600km far from me...
Now I have to find a way to properly charge my battery (if it isn't already properly charged of course!)...

But just one question: if the Kaiser is not charging good the battery, why should it "think" that it's 100% charged??

welllll.... trust me..... i once had a sony ericsson k770i. the shopkeeper said that it has ORIGINAL btry.... n it wud turn off after 20 min talk. so my advise is try another btry from another shop.....

But I tried with 2 different batteries, my old one and a new one and the problem is the same. I also have to say that it's always worse then before. Now even if I turn on the camera after some minutes it turns off, ora yesterday even when I was writing a text message.
Indeed it's possible that the battery is always less charged because the Kaiser doesn't charge it. The Kaiser works good when connected with usb to may mac...

well buddy, ur last post clearly suggests a prob with btry.... say hw much had u used ur old btry before changing it

I used a battery for around one year, but it was already used (I've bought a used Kaiser, in very good conditions, on eBay).
The problem I have started with the old battery and now it keeps torturing me with the new one... Today I had my phone charged, but after 4-5 hours without using it I received a call and of course it turned off (after the flickering screen) I'm desperate...

o boy... its 200% confirmed btry prob. i m guessing, if u wud talk with charger or data cable plugged in, it wud work for hours ryt? my sincere advice is, go to a trustworthy shop n get a new battery. i m also using a new btry but it gives really gud tym on wifi, wap n calls....

Well I really think the battery I've just bought is a brand new original Battery, I checked all codes, voltage and other stuff... BTW I think I'll try to use another orignal battery (I'm sure that's original) of a friend of mine's Kaiser before I buy a new one. Here in Italy battery and gadgets prices are really high... Thanks 4 the help anyway!
PS: I really hope it's a battery problem, because if it's something else I don't really know what to do.... thanks again!

Update: I noticed that if I don't use Camera, Wifi or even make calls at all, my kaiser works for 2-3 days with no problem. I send lots of text messages, play Solitaire or view my photo album for example...
Why just more "intensive" tasks should make my phone turn off in 2-3 minute?
I don't really understand... I hope I'll find someone in my town that can fix it... BTW thank for any help
