BT PAN: Power drain normal?

Hi Guys. I'm using BT PAN Internet Sharing (on 3G) a lot. However, the power has to stay on in order to maintain a connection, and I'm draining the battery very fast (probably around 1hr of use).
Is this normal? Is there a way I can reduce this?
When I hold the power button I expect the backlight to turn off, but not so on the Hermes. If I go to backlight settings, even the lowest setting is perfectly visible (ie there's still a backlight there).
Is anyone else finding this or am I being a muppet and missing something?

what radio version and ROM are you using...

It does have to stay on. I lock my device but expect the device to drain quickly due to the 3g data usage.

I'm on 1.18.00. It's default for South Africa, and I've no idea whether the higher versions will be better in SA, or will prove to be less tightly tuned to our exact frequency (altho GSM operators work in bands around 900 or 1800 etc, in reality each country is more specific than that).

it´s not BT PAN that is draining the power from your TyTn... it´s your 3G connection. I´ve got Chi Tai Dang BatteryStatus TD Plugin installed in my device. Without 3G/HSPDA the power usage is about 90mA (BT: on WIFI: off) ... with data connection active .. it´s over 450mA !!! I don´t know if it is a hardware bug, but the power usage of this device with data tranfer is incredible!!

Probably something to do with the separate 3g chip to the main processor. The newer combined chips will no doubt be better in the future.

Battery Monitoring Application - process related

Hi,
Is there a battery monitoring application that monitors battery usage and links it to processes or applications?
I have the excellent batterystatus plugin from chi-tai.info. HOWEVER, I'd like an application that monitors my battery over time and links it to where batterdrain is coming from and from which process. i.e. XX,YY,ZZ processes were running at this time and the combined mah drain on the battery was AAA. If it could tell what each process was taking form the battery even better.
On occassion I find my HTC (AXL rom) without any charge in the morning and sometimes i don't. It is hit and miss. I'm trying to narrow it down but my results are all over the place. I've even uninstalled some programs but it is still wild and inconsistent. I don't think it is battery drain as sometimes I wake up and have just as much battery as when I went to bed.
The application I describe above may help.
I've got a 1.43 RADIO rom and 2.08 AXL ROM on a P3600.
Cheers,
Connor

don't know if it works or not....

HTC Home also come with the plugin "Battery Status" , which allows you to see the current power drain.
E.g. when I turn the backlight on to full, it's like 150 mA/mW, but when the light goes off, it's around 60 to 70.
Also interesting when you turn on TomTom + pair a BT device at the same time and see the power drain

Not sure if you can attribute power usage to an individual application.
Here is a guide from my recent observation.
It is based on WM5 using BatterieStatus.cap, would be great if someone can do similar to WM6 in comarison.
I also used :
HTCustom1.7 to turn off HSDPA
Turned off Bluetooth and Infrared Beam
(I did discount short burst when app switching)
Idle, screen off = around 21mA
Idle, screen on, low brightness (3 notch from left) = around 62mA
As above, connected to 3G, No applications running using 3G = around 64mA
Active browsing, basic sites, 3G, around 300mA - 400mA
Active browsing, graphic intensive sites, 3G, around 400mA - 600mA
Active browsing, HSDPA on, basic site 500mA - 600mA
Passive browsing, IE open, no action, 3G, drops to 68mA
TomTom using inbuild GPS, waiting for GPS lock, 180mA
Idle, screen on, low brightness, but 'Receive all incoming beams' (IRDA receive on) also 62mA!!!
Audio call, 3G, 350mA
Mediaplayer, streaming video from internet, around 600mA.
I believe 600mA is around the ceiling.
Some calculations: Standard Batterie is 1600mAH.
So total idle/standby time is about 1600mAH/20mA = 80hours or 3.3 days
Total call time is 1600mAH/350mA = 4.3 hours approx
Total surf time is 1600mAH/400mA = 4 hours.
This lines up with my usage patterns, idle, screen off most of the day, usage about 30 mins browsing every day, batterie last about 2.5 days.

damn that's some good analysis...
Thanks

chunga168,
Do you happpen to know where can i get the HT Home plug-in for battery status.
Thanks.

3 questions. gps speed / battery / tomtom splashscreen

heya. i've got 3 questions, hope some1 could help.
i recently upgraded my p3300 to WM6 (official HTC rom) and as i was at it, started to wonder about a few things.
1) in tomtom, when configuring the GPS, i can change the baudspeed (actually at 4800). if i increase that, would a) the GPS navigation while driving be smoother, b) i get a faster satelite fix and most important: c) would the battery last less or same?
2) about the battery... i use very few apps and most of the times i make sure they are 100% closed. i use the calendar, notes and few phonecalls per day. sometimes i turn on tomtom for a few minutes to find a street when walking... but i think the battery life is very short (an average of 1% per hour in standby, more battery loss when using the pda, making calls, etc)
is there any tweaks, programs or whatsoever to see what exactly is consuming XYZ of my battery? and improve it's life?
3) after upgrading to WM6, whenever i start tomtom, i get that logo-splash screen (didnt get that before) is there a way to remove it?
i have many more doubts, but i think i'll leave em for when i solved this things. thx for answer.

1) I didn't noticed differences neither in fix time nor in navigation smoothness.
2) I doubt that it is possible to measure power used by certain application directly. I had problem with power drain and resolved it by switching applications off and on (S2U was guilty), but it seems to me that my Artemis use more power after upgrade to WM6 to.

any1 got any more comments? which is the best way to track your battery life and improve it? any program around to help on this task?

If you want to compare your device power consumption to my Artemis I'll give you some measurements (not very accurate actually):
When I tested my device while playing 320x240 divx movie with TCPMP, fullscreen, brightness set to max, no audio - battery operated about 5,5 - 6 hours before PDA powered off automatically.
During 8 hours in stand-by (I didn't used PDA at all) it was about 5-8% battery drained, but when I switched Pocket Plus indicators (memory, battery, SD free space) off - after 8 hours of stand-by there was 100% battery (full).
Hope this will help you. If you do your own measures let us know.
Good Sunday

ok, as far as i have seen, there is no application that tells your how much battery each application you run, uses. i guess thats normal.
but, is there something like the windows taskmanager, telling you how much CPU and MEMORY each application that runs in the background uses? i think if there is one, that would give a good start on my investigations.

You could try BatteryStatus

i'll try it, however i've read somewhere that this program itself is a battery-drainer already?

With BS I had 100% battery after 8 hours standby and I didn't noticed more power consumption while normal use (some phone calls, PIM, games, Internet), but you must try to know how it works on your device. Try it and then write about your findings.

Hi,
baudrate has noting to do with refreshing inverval of GPS. The refresh wrt the satellites is determined in the chipset, and the baudrate is the speed in which the chipset (which is actually an external device) communicates with the serial port of the device. Normally speaking the baudrate for gps is 4800 (it is NMEA norm), but also other rates exist for example for bluetooth devices the baudrate is only the speed with which the serial transfer of data is done. It is in the end the GPS software you use that will determine how fast your position is updated on your screen. It can happen that if you set the baudrate wrong, that the data is not received properly, because the software expects the data to be presented at the baudrate you set, and the device delivers at a different rate (like speeking too fast to somebody). It is therefore important to set it correctly.

You could try TaskManager 2.7 from FdcSoft. It shows CPU load en memory load.
Just add the .exe to the sd card and run the file. Use the tabs to selct Process / CPU or any of the other tabs.

thanks for the explanation.
going back to batterystatus, i am tetsing it now. specially the overclock tool to actually UNDERclock my phone, hoping the battery lasts longer.
however, as for what i've seen, when the phone goes into suspend, batterystatus sets back to the 201mhz until it is unsuspended. so that's actually useless.
but it tells me enough info to get an idea about my power consumption, etc.

Not exactly useless - if you read e-book or WWW pages your PDA can save power with BS (although I don't know exactly how much).
About underclocking in standby there is explanation from BS Howto:
Could you make the cpu clock down while it is in standby?
There is no need to. Most of the devices are doing this by themself. As soon as you push the power-button (explicitly not a program mapped to a custom button for this job), your device will gradually stop execution of code and clocks the cpu down.
The latter implies that as soon as you push the power-button, BatteryStatus and any overclocking by BatteryStatus stops working.
Some tests showed that your device automatically steps down to 52MHz and maybe there is a state while the cpu is completely stopped (0 MHz) too.
I'm curious what is CPU speed of Artemis in standby. Maybe somebody knows that and will share with us?

Diamond battery drain

Hello!
About half year ago I bought a new battery 1340 mAh for my Touch Diamond. Since then I could use it 2-3 days without charging.
I installed app called BattClock, which can be configured to show battery drain in mA. So I tested it with cellular radio on, no TouchFlo3D, some Today Screen Items and BattClock on. When I put my phone to stand-by mode and wake it up after 30 sec i get the current value 50 - 60 mA. Ok then I tried cellular off, all today plugins off - only BattClock on the drain value 35 - 45 mA.
I use other phone at the moment, but when I fully charge my Diamond, and cellphone function is off, also Wifi, GPS, Bluetooth OFF, TouchFlo3d Off - the battery pecent after 12 hours is 94 % without of any use.
My Device Information
ROM version: 2.03.405.3 WWE (should be default ROM)
ROM date: 02/05/09
Radio ver.: 1.09.25.23
Protocol ver.: 52.51.25.26W
I remember when I was using my default battery, I got after 2 days battery 99%.
So my question - is the battery drain value normal?
WITH ONLY CELL ON Stand-by wake up drain: 50 - 60 mA
ALL SENSORS OFF (cell, gps, wifi, blue) Stand-by wake up drain: 35 - 45 mA
And how long should the battery last without cell and any use ?
thanks,
Aleck

What battery drain values have You got with different roms?
I am sure, there are ROMs with lower battery drain results but I haven't found suitable yet.
Can anyone suggest me simple and light ROM with:
1) NO Touch Flo 3d
2) All sample videos, pictures, ringtones removed
3) FAST
4) EXTREMELY LOW BATTERY DRAIN WITH AND WITHOUT CELLULAR
5) good GPS
6) good Wifi
8) All useless removed, like help, games, getting started,
+ question: When I install a new ROM, does it have new Radio ver. also?

Hi, i'm not so regarding of the battery drain, i personally tried some ROMS but the battery life difference was not significant <but keep in mind i never tried to measure battery drain>. I currently use Gen.Y 5.5 <WinMo 6.1, Sense 2.1> and I am pretty satisfied (fast, stable and good battery life according to me).
Concerning the new radio, it is not changed when flashing a new system rom. The only way to change radio is to flash a radio rom, not a system one.

Radio also has effect on battery life. I flashed more than 7 ROMs, This one is the best http://forum.xda-developers.com/showthread.php?t=593678. I used 2 days without charging(900 mah battery). And standby 3-3,5 days.
BTW : I use radio 1.17.25.09. It has perfect battery life.

thank you! I think i'll soon give it a try but before that i do little more research.
1) Is it true, that some applications that worked under WM 6.1 doesn't work under WM 6.5 ???
2) What does the radio numbers mean?

[Q] Strange battery issue!

I have a rooted HOX with everything in stock version. I have tried solving this issue by myself but no matter what I do, it just wont go away.
I get HUGE battery drains whenever I have my wifi on. I don't use 3G or 4G, only wifi.
I thought it's a faulty battery at first, so I ran the battery test on the "HTC Function Test" (by dialing * # * # 3424# * #* in the dialer). For someone who is not familiar with it, it is a test which checks your battery usage in full brightness, screen always on, airplane mode ON for 60 minutes. If your battery discharges below 70% during the test, it means you have a faulty battery. Well, after 60 minutes my battery was at 81%.
I have underclocked the CPU's max speed at 1Ghz and tweaked the "Ondemand" governor a little so it stays more on the lower frequencies. I have also disabled ayto-sync and GPS location options and enabled the Power Saver option. I have also changed the network mode to GSM only (not sure if this makes a difference).
I also used Gsam battery monitor to monitor the battery usage and my "App usage" is the highest battery drain with Kernel (Android OS) always up there in the most apps that use the battery.
What do you suggest I do?
