Yes, I can concur with some of the observations on battery life. Sometimes, it is good, sometimes it appears to drain faster than normal.

So, I use MemMaid and check the CPU utilization and found that when the battery life is NOT good, 2 services are running and using the CPU. They are device.exe and cprog.exe which continuously use 0.1% to 1% 100% of the time. In normal cases, these 2 services would trigger the CPU once in a while. These are Windows applications which I think are used by 3rd party software. I still am not able to find out which 3rd party software triggers (or what actions I took in the software) these to run continuously.

Normally, these 2 services are cured by a soft reset. Sometimes needing 2 soft resets to get them to work as normal.

I have a strange problem while using the D2 as a UMTS modem via USB.

Sometimes he batery drains until the device shuts down - allthough the D2 is connected with a Notebook wich is connected to the power.

It's very strange. (Power over USB is activated).

The LED status shows changing green and orange flashing.

In this state I can't power the D2 via the original AC adapter - I do have to reboot the D2.

Maybe this is a hint to all those differences in battery life?!

Got my Diamond 2 days ago. (the device is 10 days old. got it second hand)

Yesterday the battery seemed fine.

Today:

Standby : 8h 55min

Talktime : 0h 0 min

Device usage: 0h 57 min.

Battery left: 14%

Something is terrible wrong. No activated UMTS, no push-mail nor push-websites.

Used it for like 10 min for GPS.

Well it's not 5 days but I can run for 2 days with my T5353.

Have set up following :

TFlo active

2 emails (Yahoo&Gmail) every 2 hours

RSS every 12 hours

Bluetooth 1 hours (using my car kit-handsfree only,no streaming)

Weather (automatic update)

Video 20-30 mins

Calls 20 mins

Also if TFLO inactive getting 3 days,but when installed SPB 3.0 battery went down to 1 day. Although it's nice I'm not interested as it's a big battery drainer.

The Batterylife increased compared to D1.

Differnt poeple reported different results in the forum.

10 days ago arrived my purchased charger and 2 Li-ion batterys from China.

One of the new batterys have identical life with the original one, but the second one have max. 40% life of the original.

Today flashed Comec One ROM and he drained the original, full charged battery faster than the stock ROM, for sure!!!

So i think batterylife depends on the quality of the battery inside ( chinese one, lower quality, or one with better quality ) and, very importand, the ROM.

Now,at 10PM my battery, with Comec ONE ROM, indicates 80% and with the stock ROM after a full day remains ~ 90 - 92%.

Take a closer look to your battery, the chinese one ( charger,USB cable and 2x battery 2.49€ + 1.99€ shipping) are worth that Ebay-money, but not in your original machine, from factory !!!
[Touch Diamond2, Pure General] munrobasher:
I suspect the battery hardware is fine in the Diamond2 but a) some applications aren't very battery friendly/crash/loop thus training power and b) it's a powerful little device so we tend to do things far more with it than you'd normally expect from a mobile phone. Use it as just a mobile and it's fine

(b) is especially the case when you first buy the thing and you can't put it down :rolleyes:

My D1 experience

Hi all after reading the entire thread (yes, 1-13), I'd like to share my experience using the D1.

The battery problem lasted about 2-4 weeks, daily charging required and each charging took a bit of time. Now after more than12 months, it's able to support a normal usage for about 16hrs. The battery pack seems to work better as it gets older.

Ensure that applications are properly closed, on D1 pressing the downward pointing triangle shows the list of application that is still active. Remember active running application does consume power.

On a final note, my experience with D1 is great, in fact I'm about to upgrade to D2 within the next 2 weeks.

Battery Stat's

I would be careful of what the Device Usage stats report.

I listen to audio books over a Bluetooth headset when I'm driving to work. The other morning I had fully charged my D2 over night, so the power screen was reporting:

stand by 0hr 0min

talk time 0hr 0min

device usage 0hr 2min

I turned on The Core Player, started the book, then turned the screen backlight off with the power button.......I drove for about 30 min to work. When I arrived the power screen reported:

stand by 0hr 0min

talk time 0hr 0min

device usage 0hr 6min!!!

I have had my D2 since it's release, and I recon I get half the battery life out of it than I used to get out of my TYTN2.....which I used in exactly the same way.
[Touch Diamond2, Pure General] root beer:
I listen to the Howard Stern show everyday in work via BlueTooth and that runs roughly at over 3 hours. I also access the Internet quite heavily and have it downloading email every 15 mins. The battery lasts me all day.

[Touch Diamond2, Pure General] munrobasher:
ActiveSync/power drain

I think there is definitely something broken with ActiveSync. My D2 is configured to be manual sync in off-peak times so at the weekend it doesn't synchronise.

This morning (Sunday), the battery was on about 75% which was perfectly acceptable. Hadn't been charged since Friday and I hadn't used the phone much.

I needed to remind myself about a few things at work so composed a couple of Outlook emails. The emails failed to send (stayed in outbox) so I manually triggered ActiveSync and it reported that it was unable to connect to the server - unusual as the H signal was about half. Took the phone outside whilst hanging out the washing and started ActiveSync again with a perfect H signal.

Few minutes later, I thought I'd got a text message but it was the battery warning indicator. The phone was also noticeably warm which is always a sign that something is amiss. ActiveSync is still failing to connect. I've just power cycled the phone and it connected & sync'd perfectly, albeit with a nearly flat battery.

I appreciate it's only anecdotal evidence but after two months of using this now, ActiveSync is the component that's failing at the same time the battery is sucked dry.

Cheers, Rob.

Remember if your phone has very poor signal 1-2 bars during this time it will drain the battery quite quickly over a day. Also make sure your phone is setup to just use the frequency bands for your country and not have it set to auto that will help somewhat.
[Touch Diamond2, Pure General] fyall:
I have had my D2 for a week now and love the phone but have poor battery life, I have a feeling I know why:

1. No mobile signal at home so I assume the phone is sucking the battery trying to find a signal.

2. Mobile signal at work is patchy so again sucking the battery trying to find a signal.

Is there anyway I can have the phone on at home and prevent it from trying to access a mobile signal when I know it will not find one?

You can turn the phone off in the Com Manager, that will stop it waisting power.

Poor battery life!

I get some thing like the above. The main reason for upgrading to D2 from D1 was poor battery life of D1. I love this phone but I am so sad that the battery life is poor again. I am concerned because some of you guys report good battery life and I dont get it like that. My battery just about lasts for a day.

Here is that stats from today:

Full charge: 10 pm last night

Standby time: 19 hours 5 minutes

Talk time: 0 hrs 0 minutes!

Device usage: 58 minutes (I only checked 2 emails, (No browsing, camera, video, music, sms etc) I dont know how it became 58 minutes. May be it is taking into account of email checking as I setup to check email (POP) every 30 minutes)

Now (5.45 pm) only 2 bars left!! I have not used the phone at all (0 mins). Even then battery is about to die!! Very disappointed! I am sure it will die before 10 pm which will make it 24 hrs.

So, in essence even with minimal usage, battery does not (or just about) last 24 hrs! which is definitely inadequate. Considering this is a smart phone and lots of other things (such as browsing, camera, video, music etc) this absolutely un acceptable battery life.

Here is my settings:

HSDPA on - setup to check emails every 30 minutes (POP)

Bluetooth off

Vibra feedback off

I am using Tmobile MDA compact V (stock ROM) by the way. Anyone using this phone confirm the battery life.?

I love this device as, its very fast and responsive but the battery life is very disappointing.
[Touch Diamond2, Pure General] jugulator:
HTC joke!

This is what HTC website says about the specifications under Diamond 2

Rechargeable Lithium-ion battery

Capacity: 1100 mAh

Talk time:

Up to 300 minutes for WCDMA

Up to 340 minutes for GSM

Standby time:

Up to 500 hours for WCDMA

Up to 360 hours for GSM

I dont know which phone or battery they were using to carry out the tests. 500 hours of standby time!!! joke?!!
[Touch Diamond2, Pure General] pauln:
Try to switch off the HDSPA, and put on to GSM not Auto.

Also turn of the touch3d.

You have GSM signal were you are ?

If it's poor it will drain your battery.

Try a better/newer radio also.
[Touch Diamond2, Pure General] Mr-Fly:
And additionally, pop3 check needs to turn on the device.

Check the turn off stuff (Energyoptions) so that it will turn off faster.

But on the other hand it could be right what you configured:

20 hours of mail checking --> Turn on device 40 times and maybe turn off after 1 minute of not using it.

Additionally use GPRS/Edge, it uses a lot less energy, also with switching between gprs and umts costs battery.
[Touch Diamond2, Pure General] swinster:
The problem I have with switching to Manual mode is that even when you specify a network to use, the phone keeps asking to register with another network when you go out of range. This is highly anoying when driving with the sat nav in operation, then all of a sudden you see a ****e message asking to register with another network.
[Touch Diamond2, Pure General] thedudelasse:
Batterylife on my Diamond2 seems to be very sporatic and is highlt affected by messenger and opera. Having them on will deplete the battery in less than a day...
[Touch Diamond2, Pure General] jugulator:
I am not being funny. These should not be the solutions. Turn off HSDPA, Turn off TF3D.. Then what is the point of having this expensive device if we cannot use any of its highlighted features. Its like saying, go and buy a nokia 5210!

I quite like TF3d and occasionally use browser and google maps, so I would like to have the HSDPA on as its much faster. One reason I think is that the network coverage very poor at my work place. It depends on which part of the department I am. That may contibuting to power drain as the radio might have to work hard looking for signal.
[Touch Diamond2, Pure General] jugulator:
I do not think pop3 check will NOT turn on the device. It works in the background
[Touch Diamond2, Pure General] pauln:
If you have bad signal you will have the battery less then 16-20h but not with all goodies activated.

If you want hdspa try bandswich 1.xxx it's last ver free :) and it's works.

I don't know if I can put it here even it's free.

When you realy need to be fast change the gear :)

For email you don't need to be fast. GPRS it's enough.
[Touch Diamond2, Pure General] sassan:
maybe, cuz mobile signal at my work is about 1 bar.
[Touch Diamond2, Pure General] sassan:
Maybe HTC should equip the phone like D2 with better battery, so it can stand for a day with moderate use.
[Touch Diamond2, Pure General] sassan:
I agree, think that the coverage is the main problem, cuz I experience the same problem with coverage.
[Touch Diamond2, Pure General] fyall:
Problem definitely coverage as I have no signal at home and my signal at work is patchy at my desk. Last night I switched off the radio under communications and my phone lost 1% from 6pm until 6am. Switched it back on this morning and came into work and after about 3-4 hours with some light use and the signal coming and going I am at to 88% so this would confirm to me that the only way to extend battery life would be to solve the the poor radio.
[Touch Diamond2, Pure General] Mr-Fly:
But if you have bad coverage, sorry, the HSDPA does not suit that situation.

Mostly HSDPA will not reach as far into buildings than GPRS/EDGE does.

I have the same at work, the windows have metal-sheets on them for protection.

If I would enable HSDPA, it would switch between GPRS and HSDPA constantly.

And that is a frequence change all the time and a send to the base-station, as it is like switching networks!

So auto is really bad in weak reception areas, thats why I switch to edge, which is anyhow about 250 kbit, that is enough in my eyes on a mobile.

Regards Thorsten
[Touch Diamond2, Pure General] Mr-Fly:
afaik, only PushMail (Active-Sync/Exchange) and IMAP Idle will not turn on the device to check.

POP3 will check the full account and download all new headers, because there is no "Push-Feature".

It might not turn on the Display, but it will definitely wakeup and do the job.
[Touch Diamond2, Pure General] swinster:
Where are the setting to turn on/off the various bands?

Is there a way to stop the registration screen from appearing when you got out of range of your network? We have 5 main networks in the UK, but you only subscribe to one and do not roam.
[Touch Diamond2, Pure General] Mr-Fly:
Actually you are mixing things up. We dont talk about the Network-Choosing Manual. This is automatic for me, too.

I do never get a registration screen, except after I have switched of the phone completely.

If you go to the "Connections" Screen on the settings (Touchflo3d) and then Press on "Telephone" (on the left side, not the right side, where the button is).

Then scroll down completely and you will find a "Band"-Setting.

Switch Network-Type to "GSM" instead of "Auto".

This will fix the phone to GPRS/Edge and will not come up with any silly questions :-)
[Touch Diamond2, Pure General] Vaxon:
I've tested the battery myself and I'm quite impressed - four days without any problems. I've had about 2-3 hours of talking, about an hour of WiFi, no GPS, no GPRS and about few hours of playing games or just doing some stuff with operating system. That is really not bad (-:
[Touch Diamond2, Pure General] fyall:
I'll try selecting GSM only. Is there a way to get the LED to flash green when in signal and re/amber when not? It would be easy to then glance at the phone to see if it has a signal without waking it up.

Standby time has a higher value if registered for WCDMA than for GSM? How is that possible? Shouldnt it be the opposite?

For the radio issue: I read it on some forums, that asian version has already an updated radio ROM, maybe it corrects the issue. Waiting for the EMEA ROM update...
[Touch Diamond2, Pure General] PhilipL:
Hi

WCDMA is a new standard and all sorts of thought went into saving power when the phone is on standby, although this is probably a sideline benefit to trying to make the network as efficient as possible by not needing phones in standby to talk back to the cell tower very often, and so lighten the load on the networks. In standby the phone is only listening, and even then it will be a listen, sleep, listen, sleep sort of thing.

However, this extra standby time is only true if you get a decent 3G signal, if you are borderline or travelling about alot then two radios end up coming into play and drawing more power as the phone negotiates handovers between 2G and 3G.

Anyone tried underclocking ? There was a post on page Nr. 2 ???

Maybe not what we're looking for , but it's a way to extend batterylife:

Just underclock your TD2 or other HTC-device:

Look here and here...

FYI: Overclocking is not possible (yet )!

[Touch Diamond2, Pure General] PhilipL:
Hi

I've tried it and it doesn't seem to make much difference, there are reasons why it doesn't.

When the CPU isn't active, for example you are just reading a text message, it goes to sleep and is using very little power. When you do something, it springs back to life, does the work and goes back to sleep.

If you underclock, it just means the CPU is slower, so it takes longer to do the same thing, so it might draw half the power, but take twice as long, so you don't gain very much, or may end using even more power as the memory and other systems are awake longer servicing the slower CPU.

[Touch Diamond2, Pure General] PhilipL:
Hi

I suspect it was stopping the phone from entering standby. Programs doing this are the number one reason for sudden loss of battery life. While your phone may still look off, the program will be keeping the phone in unattended mode, this mode is screen/buttons off but the rest of the phone is on eating power.

My bluetooth is also always connected to my phone. What I do is that in the bluetooth settings, I uncheck the "Wireless Stereo" checkbox. In this case, my phone rings as per normal and I can still pick them up using my bluetooth.
