no problem

What's the problem if your phone's on 80% battery. It still cramnks the same as if it's at 100%. I run mine right down to the bone, and it still rocks. I do about 100 calls per day (in and out), sync email on 2 accounts every hour, send 30 emails and 10 SMS per day, receive 10 faxes per day, listen to about 2 hours MP3, look up word/excel files on a 1GB storage card, ad hoc internet usage around 1 hour, and use GPS for around three hours per day. I plug it into the car charger when I am driving, and compuetr when I'm syncing files and have never had a problem. I don't even use a wall charger. You boys must be downloading some serious movies.

Poor signal can cause battery drain...

I read in the past that a poor signal causes battery drain because the phone expends more power when searching for signals... can anyone confirm this? My phone seems to wake up every so often on its own (display turns on)... not sure if this is due to roaming or due to data connectivity. I use S2U2 to lock the screen when it does wake up on its own so I don't accidently hit soft-buttons when on.

With that said, I can barely get 8hrs out of my phone. I'm usually on the phone for 2-3hrs a day, with a bluetooth headset while in the car and for convenience. I leave the GSM data up all the time for mail push. The GPS is used sporadically 2-5 times a week.

Usually have a Energizer battery pack charger along to help me through the day... decent, but definitely helps to re-charge for an hour during the day.

Oh well, the battery drain is just a hurdle in the convenience of device consolidation.
[Tilt, TyTN II, MDA Vario III General] BusterTyTN:
Previous posts: of course, the GPS unit will not be the culprit in all cases of unusually high standby current. But I think you should rule it out first. So: do not reset your phone. Perform the current consumption test as described in the first post. Give it a soft reset then, and see whether this improved anything.
[Tilt, TyTN II, MDA Vario III General] Jay2TheRescue:
Maybe if we collected more information on the devices with problems we may be able to figure out what it is. I have tried both AT&T ROM's with no issues to report, and my serial number is HT44G000xxx (Last 3 digits of s/n withheld). Unit was purchased in November 07 from an AT&T dealer in Northern Virginia. Maybe if you can get enough detailed replies you can maybe track this to a certain block of serial numbers, or to shipments going out in a certain date range...

[Tilt, TyTN II, MDA Vario III General] GSLEON3:
@ BusterTyTN, Since you seem to have the method all perfected, why don't you try doing the test using the GPS thru a GPS proxy. Maybe the use of a single Vport thru proxy for all GPS could help. That way you don't have multiple ports open, one of which could be stuck open causing an abnormally high discharge. I would like to see some comparitive discharge studies using GPSGate http://rapidshare.com/files/95732296/GPSGate.rar

I know GPSGate will also allow you to completely close & open GPS Sessions & Ports on the fly. I'd do it myself, but I'm loaded up working on a new xip port & page pool tool & it seems you've perfected the method. ;)
[Tilt, TyTN II, MDA Vario III General] BusterTyTN:
Bullseye. I once searched and asked for a suitable tool to check out the GPS port accesses, could not find one. I already thought about writing a suitable tool myself; but I have other things to do as well... Now this GPSGate sounds exactly like what I was looking for in the first place, thanks for pointing it out. I will give it a try and come back with results - - hopefully.

I still think it is the phone. I did a test to find out, and it confirmed the problem, check out

See my answer to this right there. I think you need to dig deeper first...

Results of the "GPSGate" test as suggested by GSLEON3

Installed GPSGate. Bypassed GPS COM4, added virtual COM5, configured GPSGate so that it would pause the GPS access if no client listens, and checked things once more. In OziExplorer, I changed over to virtual COM5, switched GPS on (icon went yellow) until it had a fix (icon green), then switched it off again (back to red). No problems with OziExplorer, that is. As usual, after a couple of times the phone went into high standby current without particular reason. GPSGate tray icon was red, indicating that no application listens. GPSGate settings said the same when pointing at virtual COM5 in "Output": no clients. Nothing unusual, yet the current remained high. I also unchecked Access->"Manage GPS automatically" in Settings->"External GPS" in a hope it would help disconnecting from the GPS at a somewhat lower level, to no avail. Unfortunately this is about the most you can get out of GPSGate. What I would need at this point is a tool which dumps the GPS unit's registers, and a data sheet describing the same.

I removed GPSGate for that reason; "External GPS" serves the same purpose if it comes to providing multiple GPS ports to applications (--> COM4 IS already virtual, for that matter). Right now I am trying to get rid of all this scrap which "GPSGate" left in the registry...

Conclusion: there's definitely no GPS port left open which could be responsible for keeping the GPS chip out of powerdown.
[Tilt, TyTN II, MDA Vario III General] diceman725:
Is there anyway to just simply disable the internal GPS altogether? I'm running ~100mA and frankly dont care about an internal GPS. Worst case, i have an external GPS that I can use.

Bought this phone on eBay, have had it less than a week and already tiring of it.
[Tilt, TyTN II, MDA Vario III General] grandpareza:
Phone was operating very normally 2-3% on standby for a couple of hours. Then I turned on GPS and my battery went from 98% to 93% in a matter of 5 minutes. Now after light use, the batter is at 73% after 3 hours. At the rate that it was going (2-3%) it should have been around 90% after these hours. However, 73 is what it reads.

It was as soon as a GPS app was activated that the battery began to drain. So I'm fairly convinced, as this thread has said, that the GPS is the culprit.
[Tilt, TyTN II, MDA Vario III General] spaul:
This post definitely explains my experience with both my unit and a friend's and can be related to my post "Severe and strange battery issues"; both of us suffered from the same exact problem and thought our units were defective or it was the ROM's fault.

Right now we're trying to see why's the reason that getting a GPS fix is so difficult... we're using Dutty's WM6.1 and apparently the problem (at least in my unit) has not appeared again, every morning I wake up and smile when I see that the battery did not drain by itself judging that we leave our units constantly in Airplane mode.

Best regards, hope this issue sees a solution.

[Tilt, TyTN II, MDA Vario III General] f1ip:
So I went to run a test last night.

Ran Battery status plugin. Charged phone up to 100% Hit the Close all programs.

Phone ON, Data ON, Push Email ON + 2 IMAP email accounts set to check every 30mins.

So at 11:00pm i pulled the plug to run on battery.

Hit the power button to turn off the screen.

Now at 6:30PM the next day, Turned the screen on. 37% battery left.

0 calls came in. 0 emails came in, 0 SMS

When unlocked it, using S2U2, i checked battery status, Current reading was at 242mA. So I turned that off. Put on Standby again, lowest reading was at 5mA.

yeah.. standby battery consumption does suck on this.
[Tilt, TyTN II, MDA Vario III General] BusterTyTN:
As suspected, it takes a little while for people to try this out and then the results come in. Glad to see this. Nobody can seriously continue accusing users of being too stupid to handle their phone. I think this is already more than enough proof for HTC, to justify a detailed investigation and a FIX.

I already tried to prod HTC using what they called an "escalation report", but it seems this sort of thing has a direct connection to the trashcan. Does anybody know how to get in touch with the right people there? I mean, this should be in their hands now, no?

I seem to get the fast battery drain and hot tilt when I've been using media player and turn the Tilt off with the app still loaded...

From Bad Battery to Good Battery

I'm running Alex's Tilt ROM (WM 6.0) with radio 1.27.14.09. I live in Los Angeles, CA on AT&T network and so far it has gotten me the best battery performance. I've tried numerous radios, 1.58.21.23, 1.64.08.21 and 06.04, as well as the rest of the 1.27s. The 1.58s and 1.64s all last around 5-7hrs for me with hardly any activity and just on standby for the most part. I've been reading the posts and was skeptical of Jay2TheRescue and so I checked the rom he was using, the "stock rom upgraded to 1.62.502.0 minus the bloatware." I checked out some of the other posts of users with phones that had little battery drain, and they too were using the stock ROMs. So at 8pm, my phone was newly flashed with Alex's ATT Rom v5.2 Cube rom. After checking the task manager and noticing that my standby was about 20-30mA instead of 1mA, I looked at task manager and saw batti.exe, not knowing what it's purpose was or how to uninstall it, I just closed it and now my standby was at 1% mA and while the backlight is at 50%, I get about 70mA or so. I woke up at 8am the next day, 12hrs later, and my battery was now displaying 96%. Ecstatic, I was used to losing like 15% on all the other radios. I still love .08.21 it gives me the fastest gps locks and radio reception across the board. So, back to the story, at 8pm, I checked my battery, and it was listed at 64%.So, I lost 36% in a 24hr period. I had about 30minutes worth of phone calls, an hour of wifi with the phone off, probably 30 minutes surfing the net and another 30minutes worth of gps using live search. I know that if I just use the phone for phone calls and not browsing the web or gps, I could easily go 3 days without charging. I can't believe the battery life with the stock rom, even though I don't like it as much as duttys or sleuth's but the battery life is definitely phenomenal.
[Tilt, TyTN II, MDA Vario III General] BusterTyTN:
@ 6thelement, Kosiak: Please review the first post. My investigations included "fresh" ROM installations, and assumes that NO energy intensive applications are running. No "batti.exe" - whatever this is. I know there are numerous other factors which will increase the power consumption of your phone, but this has to be discussed elsewhere.

If you start and stop GPS often enough, the phone sometimes falls into a mode where it draws high power during standby, that simple. What I have not mentioned earlier is that you can get the phone out of this condition if you repeat the very same on/off sequence, besides applying a soft start. I have tried this with both HTC's GPS Tool, with OziExplorer and Tomtom. Somehow this tastes to me like the GPS driver can be left in a "bad state", if the GPS port closes at a right time during the NMEA communication. It does also seem to me the phone is more sensible to this effect if it is cold, though I am not sure.

An interesting point is the one about the stock ROMs vs. all others, though there needs to be further proof. I am using Duttys_Official_WM6.1_Rom_5.2.19716_UC and radio 1.64.08.21. I would be glad to try a "better" radio if somebody can confirm that I do not need to force the phone into a cold reset.
[Tilt, TyTN II, MDA Vario III General] Nakel:
My experience may shed a little light on this problem. I posted earlier that I was not experiencing this problem with Garmin XT. That Tilt then died and has since been replaced. I noticed excessive battery drain on my new tilt, so I did a hard reset, the new 1.62 official ROM, and installed BatteryStatus. No problems here. Normal power usage about 70 - 80 ma. Standby battery drain 1 - 3 ma. I next installed Garmin XT, lo and behold the problems started. Normal power drain after using, and properly closing, Garmin about 140 ma. Standby battery drain about 70 ma. Soft reset cures the problem until you use the GPS again. We're talking about an extra 60 - 70 ma battery drain at all times... Standby or not.

So, I have the problem now too. But my experience indicates that not all Tilts/Kaisers have the problem. In fact, My wife's Tilt does not have this problem. So there is definitely a problem with some units. BTW, the build date, ROM, etc is identical between my wife's Tilt and mine.

I hope this helps figure this out. Thanks for everyone's effort on this.
[Tilt, TyTN II, MDA Vario III General] BusterTyTN:
@ Nakel:

yes, the standby current adds to the overall consumption, at all times. It's just most disturbing in standby, though it also shortens the runtime if you keep the phone running all the time (Media Player or so), but except GPS. Maybe I should clarify this on the first page. And add a note that many Kaiser's suffer, but some not.
[Tilt, TyTN II, MDA Vario III General] M@ster:
I tested for a few days and everything is like I described before. I activated GPS over 10 times, WI-FI and ect. and never had excessive drain problem. I don't know why so many people have that problem but only logical explanation to me is Radio or some other third party software, or maybe some units have problems like Nakel said.
[Tilt, TyTN II, MDA Vario III General] grandpareza:
You know, for the first time, I fired up palringo and talked to friends for about an hour. My battery went from mid 90's to 51%. It wasn't on standby or anything, and google maps, Qgps or anything gps related wasn't running.

Only palringo...is there an explanation for that?
[Tilt, TyTN II, MDA Vario III General] BusterTyTN:
Yeah, this really sounds like there is a device dependent factor in there, chip revision or the like. Nevertheless, since this fault is reversible (recovery is possible through repeated cycling, or soft reset), I do not believe in an actual hardware problem. A certain hardware dependency, yes. I am sure it is a very common software problem, a programming mistake, such **** happens all the time. My bet is that the GPS driver leaves the GPS chip in an indeterminate state when the port is closed, probably some critical access timing of the hardware registers, an invalid access sequence, buffers improperly flushed, not all registers serviced (correctly) or so. There are thousands of things to look for, and I am sure this is something relatively easy to debug, but I am afraid we're not the ones to find out. I would like to, but I do not have the least documentation about this piece of hardware.

Having said this... hey HTC guys, get in touch with me !!
[Tilt, TyTN II, MDA Vario III General] grandpareza:
Buster, can you make a table of battery draingae with your method, and other ways

Example

GPS ports closed - x%

Gps ports open - x%

3G on with GPS ports closed/open - x%

normal use with gps ports closed/open - x%

normal use with gps ports closed with no 3rd party app - x%

normal use with gps ports open with no 3rd party apps - x%

and the opposite of each possibility.

it does seem like a lot of time, but do you think something like that could give a benchmark as to how much battery is being drained compared to other types of uses?
[Tilt, TyTN II, MDA Vario III General] f1ip:
yeah, palringo sucks up alot of battery. I have Octrotalk installed, it drains the battery in 20 hours or less if it's on for more than 4 hours.
[Tilt, TyTN II, MDA Vario III General] svcglobal:
Not being a scientific way for electronics measurement but, new TyTN II with stock ROM/Radio, bought March 1st and received two days ago loose approx. 5% every day after MioMap 3.3 installed as a GPS software. With this pace, the battery will last very long. Only Phone service is switched on and only one battery top up.
[Tilt, TyTN II, MDA Vario III General] BusterTyTN:
I already made some measurements with my first phone, see below. Generally, if GPS is active (port open) it will draw an additional +800..850mW or so, which is second to none when comparing all subunits, I'd say. After closing the port these 800mW should disappear completely, but as we already found out the GPS chip sometimes consumes an additional steady state power of 100~400mW, for unknown reasons. I'll follow up with some 3G figures later on (none available in my area), though this is of no relevance here. A very important observation is the DC or steady state character of the current, a clean flat line, which says that the unusual power consumption is not caused by processor activity. The latter would look quite irregular. You may look at the scope screenshot which I moved to the first post within this thread.

The normal 1.35 Ah battery has an energy content of >5 Wh. Battery drainage in %/h equals to 100% * Power / 5 Wh. Similarly, battery uptime would be 5Wh / Power, in hours. I verified everything with measuring instruments, and all the figures fit nicely to each other, so I am not looking at this any longer.

**********

1. Pstby = 0..3mW (reference for the following)

2. Pon = 155..180 mW (reference, set to lowest brightness, no task running, didnt touch screen nor buttons)

3. Pon+20mW = 175..200 mW GSM phone logged in, no calls

4. Pon+5..10mW = 160..190 mW BT on, no link

5. Pon+130..400mW = 280..560 mW WLAN, no data transfers

6. Pon+850mW = 1000 mW GPS on, SW running (OziExplorer or GPSTest), with & w/o GPS fix

7. Pon+200mW = 340 mW On, after GPS access. Same situation as 2. otherwise.

8. Pstby+180 mW = 180mW standby, after GPS access. Same situation as 1.

9. Pon+380mW = 540 mW Mediaplayer running, 0%Volume

10. Pon+530mW = 680 mW 5% volume, internal speaker

11. Pon+260mW = 410 mW, 5% volume, display completely off
[Tilt, TyTN II, MDA Vario III General] BusterTyTN:
Right, not exactly the scientific way... To be precise, it does not make the slightest difference whether you installed a GPS software or not, as long as you do not use it. Leaving your GPS software running all the time, you will see a drop in capacity of 20% per hour, give or take. This GPS hardware really needs juice. The 5% you are referring to are solely drawn by the cellphone hardware (base current plus occasional background service). You probably do not use 3G. I've heard this takes a serious amount of additional power, but I have to try this myself and gather some numbers, see previous post.

[Tilt, TyTN II, MDA Vario III General] scm2ejm:
I've found another cause of drastic battery drain. I use both TCPMP (for flash and files with an AC3 stream) and CorePlayer (for everything else). The other day I opened a large .avi file in Coreplayer (about 200+mb) with max battery, then paused it so it was not playing and turned off my Kaiser. When I turned it back on a couple of hours later it had almost no battery left! I assume we have to close the program from memory entirely to stop this drain. Hope this observation was useful to someone.
[Tilt, TyTN II, MDA Vario III General] BusterTyTN:
Nothing really "standby consumption" related, but an application related issue. I assume the player continues looping all around when paused, probably keeping the phone from going into standby. The program does not need to be "closed from memory" (exit / terminate, you mean?) as long as it does really nothing. I am sure a clean STOP is enough.

Why not check the battery current when you do this, and see whether it goes down after stopping the player?
[Tilt, TyTN II, MDA Vario III General] svcglobal:
No, I am not using 3G, only GSM. And HSDPA and WiFi also desatived.

But the main issue in this thread is excessive current drain after using GPS and not with GPS actived.

So, clearly, as I wrote, absolutely NORMAL drain I get from my device used as a phone and even after a couple of GPS runs.
[Tilt, TyTN II, MDA Vario III General] tmac750:
Hi all first post.

I have been reading alot and just let say great site here!

I bought 5 tilts for my company and they work great except 2! Mine and one of my techs. They drain in half the day to 30% to 20% while only using the phone maybe 5 mins and IM about 20-40 mins. The IT Admin's phone played a movie for 2hrs with WiFi and bluetooth on the whole time and was only at 72% at the end of the day!! he still hasn't charged his and its at 37%! Mine has been the worst and I have to charge it 2-3 times a day! I am taking it back to AT&T they said they would give me a new one but how can I tell if it's gonna do the same thing?
[Tilt, TyTN II, MDA Vario III General] svcglobal:
Post here the ROM/Radio configuration (of each one, if different). Should be interesting to know what firmware those devices are loaded.
[Tilt, TyTN II, MDA Vario III General] BusterTyTN:
Definitely. As soon as we have enough information about good and bad phones I will follow up with small summary which will show us whether this issue is ROM or radio related.

@tmac750: I hope I am not asking for too much - can you also execute the test as described in the initial post, before your phones are replaced?

Lastly, I wouldn't ask anybody to post this information right here, but we should not forget to keep track of the serial numbers and the IMEIs. Assuming that we can put this data together, HTC may be able to derive a common cause for the problem, like specific chip revisions, assembly lots or so.

Unfortunately I'm out until the 16th, so please keep the fire burning!!

Thanks

I've had the orginal rom install, would normally get 1 weeks worth of of the battery on standby I hardly use the phone on my kasier.

Last night installed the newest dutty rom, the cubed one.

After install, the battery meter had shown that the battery was dropping 1% every 30 seconds to 1 min.

my feeling is that while the dutty rom is ok, I think it's running stuff that chews up the CPU cycles too much thus chewing up the battery too much.

What sort of battery is in the dual touch? which is where the cubed software comes from

on a side note was finding the software to run a bit slow compared to the old rom.

The old rom I had install I had used it for about 6 months.

May I suggest using PowerGuard for measuring battery current, temperature, etc. I wrote this tool, since I also noticed unexplainable battery consumption once on my Polaris. PowerGuard gives you the opportunity to define a current threshold, above which it will notify you of high battery consumption.
[Tilt, TyTN II, MDA Vario III General] daghood:
I am aslo using your tool and would like to know the best way to test my POlaris. I hard reseted my polaris and then installed ONLY PowerGuard and look at the battery consumption ! Then what else should I do? I also see some peaks in the power consumption (down to -400mA for 1 or 2 seconds every 5 minutes), no idea where it comes from?

Have you been able to figure it out?

Dag
[Tilt, TyTN II, MDA Vario III General] Muyz:
I noticed very high power consumption only once. It was gone after a soft reset, and have never had the problem since. Of course, I run PowerGuard all day ;-), but I do not see the pattern that you mention. However, I will try harder this evening and try to reproduce it by leaving the Polaris on...
[Tilt, TyTN II, MDA Vario III General] pietrucci:
wow...

Wow, my phone shows a permanent currency of 730 mA, both with Batterystatus and with PowerGuard!

I softresetted several times, close everything I could close with taskmanager (including several services).

What's the matter???

Could it be that my battery's nearly dead? My phone is empty after about 8 hours nowadays.

EDIT: Did a hard-reset of my Dutty 19199 Ultra-Clean ROM (radio 1.58.16.27): without any extra install still 750mA currency.

Used aother radio's also massive battery drain.
