what did You just say???

I am quite sure, that Your kaiser must be faulty. I am using mine just normally- some browsing/email both 3G and wifi, about 4 calls and 3 messages, gps for about 30 minutes (wrong god damn junction... don't ask) and some general use like photo viewing and lil bit of mp3 playing.

guess what? 66% of batt after about 15h.

what more- when I am going to sleep with 100% batt then after about 7h I get 94% on standby, so I guess that it would last for more than 24h.

I'll run some tests, maybe even tomorrow. I'll swap my sim cards with my ol' trusty v3i and will leave kaiser on standby for... well.. as long as I can. ;)

good thread- never heard bout this issue before, but it seems to be a REAL problem, if You know what I mean.

AT&T Tilt 1st edition ROM.

I can get 4+ days of power out of the phone with several short phone calls in a day. 30+ at 10 minutes each +/- 5 minutes.

I usually only connect to HSDPA to get the weather. I don't use wifi, and GPS rarely. I check web based email probably once a week from the phone, and may check other websites perhaps once to twice a week. Time on HSDPA / 3G limited to probably 30 minutes total in a week.

I always turn the display off when not in use.

I don't run games very often (NetHack occasionally). 3 times a week, for 15 minutes each session.

On average, I lose about 10% to 15% battery a day. Some days are a bit heavier, others not as much. I balances out to 4+ days before I put it on the charger.

I would likely be the anomaly though. I don't use many of the features of the phone.
[Tilt, TyTN II, MDA Vario III General] BusterTyTN:
Jay2TheRescue: yes you did it right; no GPS overnight, of course (except you want guidance in your bed). Thanks for spending the time. I still believe you can get your Kaiser into that situation, somehow. Never mind, in your case the risk may just be sufficiently low. You know, this ***** can't quite be characterized by good repeatability. One of the phones I tested needed approx. five tries until I succeeded.

Andalyn: if you don't use GPS, you won't get into this problem.

We have to be aware of this hairy bug. As said, users do not even consider that there is a problem. They use the phone normally, recharge it every day, and wonder why HTC used such a small battery. Without knowing that there is a permanent 50mA or so nagging at the battery, all the time.

[Tilt, TyTN II, MDA Vario III General] samsat:
BusterTytn,

I do use GPS periodically. I wanted to see if after having done so my phone may have been in the high current situation you describe.

I am not about to possibly force it into this situation but will make sure to check each time after having used the GPS.
[Tilt, TyTN II, MDA Vario III General] Jay2TheRescue:
Because HTC didn't want to make a phone as big as this... (And by the way, you were lucky to get 10 hours of standby time with a DynaTac.)
[Tilt, TyTN II, MDA Vario III General] DarkDvr:
Oops, misspelled it, end of year 2007, not 2006. Sorry.

24 hours in standby is unbelievable to me, I never had such a huge battery drain.
[Tilt, TyTN II, MDA Vario III General] Foiled:
I have read though all of this and I noticed no one is talking about their memory cards.

I just did a test and if I remove my memory card "2 gb kingsten" My Tilt uses 20mA less. I have played with this for more then an housr now and the card use up some power. With out my card in I use 2mA in standby with only the phone radio on.
[Tilt, TyTN II, MDA Vario III General] Jay2TheRescue:
I have a 4Gb Sandisk micro SD installed on my Tilt, and it is always there. I never remove it. I still get 1 or 2 mA in standby with the card installed.

@ HarleyTheGod, f1ip:

seems you are looking at precisely the same thing: totally empty within a day or so, without doing much. Don't your phones get a little warm?? As far as I could determine the hottest spot is on the back side, somewhere below the main camera. I strongly recommend that you capture the standby current consumption as described within this thread. Do not soft reset your device until you did that. If you got the results, you can soft reset the device, and I am very sure you will be surprised about how long your battery can last !! And please, post your results here.

Interesting hint about the SD card. Will repeat my tests and see whether the card has any impact.
[Tilt, TyTN II, MDA Vario III General] Highflyer_andreas:
I have the same problem. I described it earlier as battery sudden death but i think you have found exactly what is causing this. I measured sby current and found it 1mah. Then turned on a gps application for a couple of minutes, turned it off and but the phone on sby again for 5 min. then measure the current again... lowest was 100 mah. Thanx for the info. Until we find a fix for this i will have to double check everytime i use gps and then reset...
[Tilt, TyTN II, MDA Vario III General] BusterTyTN:
Took a while, this time I had to activate / deactivate GPS six or seven times until I got the phone into the "power hungry" mode... Usually it takes merely one or two tries. Anyway. I removed the SD card, the standby current did not change at all. Put it back in - zero effect. Have not tested whether the excessive current appears only if the SD card is in, but I doubt that. Will test later.

In case a HTC representative reads this: you should have put a "fingerwarmer" icon on the "Today" screen for this one.

3G or GPRS

We're not taking the data into consideration here. I can get about a day and half out of my kaiser in a 2G area (GPRS) but that goes down to about 10-12 hrs in a 3G area.

Stu
[Tilt, TyTN II, MDA Vario III General] BusterTyTN:
@smads

'course. If you do not need GPS at all you are out of risk anyway. You won't see any of these effects until you used the GPS module. Once more: this thread is not about short battery life due to heavy usage, GPRS, 3G, WLAN or whatever.
[Tilt, TyTN II, MDA Vario III General] Jay2TheRescue:
My phone went about 18 hours yesterday (6 am to midnight). When I plugged it back in I had 58% battery. Here's my usage yesterday (all in 3G)

11 3G voice calls totaling 1.5 hours

About 45 minutes HSDPA data usage with internet explorer.

Played Solitaire & Bubble Breaker for about 30 or 40 minutes in total.

I ran the GPS test twice. (Opened Tom Tom, waited for GPS lock, then closed 3 times, then put phone in standby and checked power usage a moment later.)

Ran Tom Tom 6 & Navizon together while driving around for about 30 -40 minutes. Unit was cradled in a mobile charging cradle for that 30 minutes. (This was at about 11:30 am.)

About 20 or 30 minutes of miscellaneous usage (Checking time & date, checking, adding, and changing appointments, looking up stuff in contacts list, etc.)

All said & done I don't think that's all that bad considering the usage the phone got. I think the effect of the charging cradle was neglible at best because it was only in use for 30 minutes, and the whole time the phone was scanning WiFi networks and cell towers every 5 seconds, and using GPS. I really don't think any signifigant amount of charging was going on, since I was running 2 power hungry applications while it was plugged in.

-Jay
[Tilt, TyTN II, MDA Vario III General] BusterTyTN:
@ Jay2TheRescue: your battery charge figures sound alright. At that level of usage it won't even matter if your phone keeps your pocket warm in standby, as a side task... Seriously. Stay suspicious, and please keep on checking the standby-only current every once in a while, after poking the GPS chip a bit. It's not that important what happens if you torture your phone, because the currents involved will put anything lower than 50mA or so in the background.
[Tilt, TyTN II, MDA Vario III General] HarleyTheGod:
I tried this test:

I removed my SD card, put the unit in Flight Mode (everything off) and did a soft reset.

According to BatteryStatus it's still pulling 230mA with the backlight on normal (5th hashmark) an 195mA with the backlight on dim (1st hashmark). This is approximately the same current load as before the soft reset with the phone on (bluetooth & WiFi off) and the SD card installed.

Ever since it came back to life after the RLoD incident it's had a short battery life.
[Tilt, TyTN II, MDA Vario III General] Jay2TheRescue:
I wonder if someone could write a pocket warmer application??? ;) I don't keep it in my pocket anyway, I have a leather belt holster for it. I get paranoid about putting it in my pocket, I don't like anything that generates RF that close to my jiggly bits.

-Jay
[Tilt, TyTN II, MDA Vario III General] BusterTyTN:
@Jay2TheRescue: Thats right. I'm no less paranoid. Did you know, in Italy you can get trousers with copper mesh added to the critical areas!!

@ HarleyTheGod: This has nothing to do with the standby currents triggered by the GPS. Suitable case for a treatment, I'd say. Assuming that this is a non destructive thing, you can try to pull out the battery, leave it alone for a few seconds (or make it a minute), and put it back in. Good luck ... Buster ("R1").
[Tilt, TyTN II, MDA Vario III General] Jay2TheRescue:
So I don't need to be lining my boxer shorts with Aluminum Foil anymore??? You know we joke about it, but when I was younger I used to drive an ambulance (Hence the name...) Anyway, a lot of the drivers would leave the mic to the radio in their lap so they can find it without looking down. I don't know how many of you are familiar with the old Motorola UHF mobile radioes, but the mic had an increadibly huge magnet in it. I absolutely refused to do that. I learned the layout of my trucks and I could grab the mic from the dash clip without even looking. They thought I was crazy but I was not going to subject myself to testicular cancer or have FLB's (Funny Looking Babies) later in life.

In the spirit of continuing to be OT, (Mods, this is my last OT in this thread... I promise!!!)

Well, at the time there was a big thing about law enforcement officers getting testicular cancer from using handheld radar guns. They would clock someone, then throw the unit in their lap without turning it off and go on persuit... After that a lot of the departments stopped using the handheld units, and started using the vehicle mounted radar.

It certainly does not do any harm to keep RF sources away from certain areas of the body...

[Tilt, TyTN II, MDA Vario III General] dardar2:
Hello

Me too I'm having this problem. Therefore I do a soft reset everytime after I use my GPS. Normally with gsm (no 3g) turned on, I lost 2% per night.

I have seen my phone loose 40% during some night when everything was off (plane mode? fly mode?). Also my phone is a polaris and not a kaiser but I do have the same problem long before I saw this thread.

Regards

Dara

edit: 2% per night= my device never report the battery correctly. usually when the battery is below 50%, it drops faster.
[Tilt, TyTN II, MDA Vario III General] BusterTyTN:
Hmmm... Kaiser and Polaris. A problem common to ALL HTC PDA phones with built in GPS, finally?? Now I wonder whether there is a difference whether the phone is based on the Qualcomm, TI or Samsung chipsets, but so far I do not have much information regarding the similarities in the GPS hardware. I also saw reports about other HTC phones having similar "suddenly empty" problems but ignored them so far since these were no "Kaiser" derivatives. Perhaps I was too shortsighted on this one, and the story is way bigger in reality...

So anybody calling a HTC with internal GPS his own, please spend the time and contribute a few cycles of the GPS / standby current test as described in the introduction to this thread. Your results are important!
[Tilt, TyTN II, MDA Vario III General] digitalninjas:
I just upgraded to 6.1 as well and with it on standby all night and an alarm set for the morning - over 8 hours I lost 20% :eek:
[Tilt, TyTN II, MDA Vario III General] clementluy:
My Kaiser hardly > 24 hrs

hi all,

thanks for having this thread to discuss. My kaiser hardly last > 24 hrs with bluetooth on. Anyone can tell what is your result by doing this ? I received & made call in total 1 hour a day.

thanks
[Tilt, TyTN II, MDA Vario III General] BusterTyTN:
Do I assume right that you mean your phone is in standby for most of the time? If so, I would not expect that much battery discharge, even with bluetooth on. Subtracting 25% battery capacity for the phone call, the remaining average consumption must be somewhere around 40mA. That is well within the range I mentioned. Soft reset your device, see whether this mitigates the situation, and please post your result here. Thanks...
[Tilt, TyTN II, MDA Vario III General] benchMarc:
I'm getting really annoyed by battery drainage. Yesterday evenight at 11 it was on a 100% charge. I unplugged it, and 8 hours later when i woke up it was at 85%. Then i went to a customer, used TomTom for about 15mins. Made some notes, used the internet a couple of times (but no longer than 5min each session), made a couple of phone calls which were really short and i made an email. I've got 3 mail accounts that are checked every 15mins. The connection automatically closes after 5mins. I already put my phone on GSM mode instead of 3G, because 3G drains it hell of a lot faster. Now, at 8pm i checked my battery again... and it's on 24%. This is unacceptable. If i used TomTom for a bit longer or made a couple of phone calls more, it would be drained at 3 or 4 pm. It even happened to me earlier. Today after using the GPS i soft resetted it, just in case. So that can't be the reason. It's just a battery eater :/
[Tilt, TyTN II, MDA Vario III General] M@ster:
I change Radio to 1.27.12.17 and I don't have excessive battery drain problem. ROM is WM6.0 cooked by myself. I tested with GPS without reseting the phone, and overnight I have only 2% loss. Of course, in the morning I reset the phone an battery was the same.

Model is Tytn II, no Tilt.
[Tilt, TyTN II, MDA Vario III General] BusterTyTN:
If overnight loss is just 2% you were lucky and the phone did not make it into the "bad mode". Then you do not need to reset it to correct the battery display. Typical symptom is that the battery gauge went way down, and keeps falling ~1% every 30 secs when turning it on again after a long while. In that case you should reset the phone, during the warm boot it will update the battery capacity.

Other than that -- do not feel too safe. Until now this issue looks independent from radio and operating system. You may just need to activate the GPS unit more than once in order to see something. Which is good or bad luck, depending. Sometimes the phone is OK after using GPS, sometimes not. I've had times when I needed to check more than five times before something happened, other times I was able to check five times and the fault popped up always.

@benchMarc: this is likely to be "heavy use" related stuff, not the problem described here. If you allow your phone to check your mails every 15 mins, and the connection stays active for 5 mins each, you won't get too happy with your battery. Extend the 15mins, or keep the connection time shorter, I'd say. A running GPS alone drains your battery within ~5 hours, max..
[Tilt, TyTN II, MDA Vario III General] benchMarc:
i also have that strange thing with wron battery indication. it was on 24% left, but when i soft reset the device it is on 38%. after a while it drops again, i reset, and it's about 14% up again. really weird. btw, i doubt it that i can use gps for that long. with tomtom max 1,5 hour or so.

Anybody tried one of these: HTC TyTN II High Capacity Battery 2700mAh 3.7v Li-ion?

http://www.gpsforless.co.uk/product_details.php?id=11658

Does it last longer? Thoughts please...
[Tilt, TyTN II, MDA Vario III General] Jay2TheRescue:
I don't know about this one... I've been thinking. If you have to start and stop GPS 5 times for this to happen, then it really shouldn't be an issue. It sounds to me its like stopping your car in front of a brick wall, and then jump the clutch, let it stall, restart the car, jump the clutch again... until the car doesn't stall once and it runs into the wall. I use GPS a lot. Sometimes as much as 13 or 14 hours in a day. I've never had any issue similar to this with the Kaiser, or my old HTC Beetles. I'm thinking this is either a ROM issue, or maybe an issue with a specific batch of chips that HTC purchased, but I don't think it effects all devices.

Of course, YMMV, I'm just speaking of my experience with my 2 HTC devices with integrated GPS.

-Jay
[Tilt, TyTN II, MDA Vario III General] BusterTyTN:
@JetDriver330: Easy: the more capacity, the longer your phone lasts, at least up to the point where self discharge starts to play a significant role. The 2700mAh doubles the battery uptime, but recharging will take longer as well. And you have to make sure that it fits, because the battery is thicker, as far as I know. Somewhere I read that you need a different back cover for your phone. Where to get that I don't know.

Absolutely. One of the early assumptions was a bug in the hardware, which may not be present in all chip revisions. Believe it or not, my fate is that I always get the misbehaving samples. This is good as long as I have to check out semiconductors (engineering samples), but it drives me nuts when my tools don't work right. You seem to be in a better position; I am sure you tried this out often enough now. Another supportive fact is that the erroneous standby current varies between devices and even operating systems. There is a variable in there, which may also mean you won't be confronted with the problem if this variable is below a certain limit. Latch-up sensitivity or something. But I believe this is out of our hands. Only HTC has all the data to derive a correct fault analysis.

I slightly disagree in that it is not an issue when your phone goes dead once in five times. And it's not even a kind of abuse or particular stress, like stalling an engine. This is a normal activation and deactivation process, maybe comparable to what the milk man does with his car.
[Tilt, TyTN II, MDA Vario III General] LGB:
Finally!

I have not been online for a while because I have been busy, but I finally came here for this problem in particular - happy to see it at the top, as it is really crucial!

In the beginning I was disappointed over the TyTN II / Kaiser that I did not last as long as I am used to, just because I activate some of the features - duh! That was then, now, since a month or so, I have had the same problem as described in this thread.

A while ago I got myself one of those external batteries i-up 5400 mAh batteries, and it kept me going for days, or, I could use the GPS for entended times with no outlet. It lets me recharge the Kaiser 3 times or more, on the same charge, and the size is just about the same as the phone, thicker, but narrower. I think it is ... 127 grams? Anyway, this external battery am now making my Kaiser just making it though a normal day!!! And dig this, I will use today as example:

0930: Unplug from charger with 100% charge. All is turned off, even 3G, except mobile phone. No programs are running, no bluetooth, wireless or anything. I am so tired of this battery issue, I am only using it as phone for the moment!

I tried to make too calls today, but my sim-card needs topup. Received two calls, less than a minute each. At 4 in the afternoon, I get a message (the first of this day), when I look to see it is a battery low warning, 18% left. I pull out the portable charger, as I am on the move and don't want to sit around and wait for a recharge.

Some facts:

Kaiser TyTN II, Danish model, one of the first models, original ROM. 6 GB memory card, almost full. TomTom and MapKing installed, but I have not used the GPS for weeks. Quite important here: I rarely turn it off, just use the standby function. Maybe I should turn it completely off every evening?

Sometimes I have problems with accessing the phone after a call, cannot open anything. Go to standby and back fixes the problem.

I want to know what the problem is, not what it "maybe" is, otherwise I might as well carry around a small laptop with the same functions (and more!).

Looking forward to a solution here!
[Tilt, TyTN II, MDA Vario III General] LGB:
By the way, I am not so sure it is something with the GPS.

As I said, I did not use my GPS for a few weeks, and I only use wireless at the moment a few times a week, for a few minutes. No bluetooth either, no 3G (So why a Kaiser then - good question!)

I think it is the phone section, not the GPS, that has a problem. I have tried to leave my phone at night, in the AIR mode, since I only use the phone, I just disable the phone, and it is already in air mode. In standby at night, the next morning it still showed 100% (maybe a mistake?). Since the only thing I have activated, and use, is the phone (3G deactivated), there are not so many other options left. Why should the GPS draw current, if it is not activated?

Also, my phone does become warm in standby, just doing nothing. Well, something is happening, because phone becomes hot, battery becomes dead - I think the phone is playing solitaire against itself all day, when the screen is off!!!!!!!!!!!!!!

SERIOUSLY ... I am just thinking of one thing that is worth investigating. I think I am in an area where the signal is varying, as I am moving in different rooms most of the day, and maybe the coverage is not so good everywhere. Maybe the phone is very stubborn trying to maintain GSM contact, and thus uses a lot of power if the signal is weak. I am used to an old Nokia 6310i which still last me 10+ days on standby, even now where it is over 4 years old!

So, poor GSM/3G signal => High battery drain?

Also, I am just "upgrading" from Dell Windows notebook to Apple Macbook Pro (hee-haw!) - I know it is a completely different kind of windows, but I cannot help to think of all the times window is hanging for some stupid reason - like anti-virus program going into a 100% eternal CPU loop over something trivial ...
