Diamond 2 battery can't last a day

I had been using my Diamond 2 for last 7 days. The battery life is slightly longer than my Diamond1. But definitely won't last as other users said : 5-days!

In fact, the battery most likely last me for about 10hrs!

Well.... my Diamond2 have the following thing in use:

Every 15mins checking stock update.

Every 1 hr checking push website.

Every 15mins checking POP3 email

Connected to my office exchange server, once email in, it will updated.

Phone calls is about 30mins.

SMS in/out is about 40 for the mention 10hrs period.

No mp3 or video play, no take photos, no Bluetooth, no Wifi.

Only 3G & HSDPS is on.

So.... it is normal? or I have to go back to check on my battery with the distributor?
[Touch Diamond2, Pure General] adesonic:
If it is only lasting 10 hours you have a problem, or maybe your battery meter is not calibrated yet
[Touch Diamond2, Pure General] swinster:
I have 11hrs on time since full charge, 14mins talk time, and 1hr 45 of use time (was playing with Wifi and VPN's today at work).

After this I have around 20% battery charge left. Not that good.
[Touch Diamond2, Pure General] shawchyn:
May I know how to do a battery calibrated?
[Touch Diamond2, Pure General] miksa:
i have made some battery 'tests' (just subjective feelings) and find out that mine diamond2 biggest energy eater is WIFI. It was enabled for first few days of using (I bought it on Apr 30th) and I had to charge each evening, sometimes more frequently. After reading this thread I switched WIFI off and am switching it on only when needed. It is connected in about 2secs so no problem.

Also backlight is set to mid level by default (no automatic backlight).

My current status is:

Last full charge: 14:39, May 18th 2009

Stanby time: 16hours 35minutes

Talk time: 5minutes

Device usage: 57minutes (gprs data & wifi & playing with PointUI Home2 ;))

My current battery is 71%. Seems to be ok for now, no way it can stay for 4-5days. Maybe when no sim card inserted and no display switched on :)

I will post info tomorrow about the battery.

[Touch Diamond2, Pure General] Mr-Fly:
I think, that the disconnect will cost you battery.

it means you make a new connect every 5 minutes. The connect takes a while and uses energy.

Why do you disconnect ?

I am using edge anyhow, as it is more widely spread and I dont have so much switches between the networks (3G/EDGE) which always costs battery.

Regards Thorsten
[Touch Diamond2, Pure General] XionaxPDA:
Disconnecting the 3g connection will result in the device using GSM network. I did some testing and it feels like it is lasting longer.

With 3g the battery was empty after 10 hours. Now the maximum of 2 days can be reached on one battery.

Another dutch website says:

Charge the battery the first few times more than 12 hours instead of the 3 hours advised by the manual. With normal usage the device should hold 2/3 days.

[Touch Diamond2, Pure General] shawchyn:
3G network is always 'eat' up the battery faster than GSM network. Especially if you ISP 3G network is not stable, you phone will swifting from 3G to GSM and back to 3G. This will definite drain the battery faster than ever.

But, I can't turn off 3G as I need fast data connectivity for me to receive emails and updates on the website. So GSM is too slow for me. :(
[Touch Diamond2, Pure General] XionaxPDA:
I've setup my device so it will always use 3g and HSPSA for data transfer. But if its not using 3g it will switch back to GSM... so I still have the fast data transfer.. but not for voice calls.. only for data.
[Touch Diamond2, Pure General] Mr-Fly:
I dont know how you setup this behavior.

But my device only allows Auto or GPRS.

That means, also phone calls will be held through 3G frequencies, if the network is available (shown by the 3G symbol on top, but no data 3G symbol).

if set to GPRS/GSM it will be G or E Symbol.

For T-Mobile Germany, Edge is available nearly 100% so, that is my connection type I am using.

[Touch Diamond2, Pure General] paalkr:
Hi!

I have played around with my device a lot lately :D, and it looks like that enabling Wifi (only when available though) drains the battery extremely fast. When only using 3G the battery last much longer, even in suspend mode, so does the wifi stay connected or use more power than 3G in suspended mode?

hi bro, how do you switch off the 3G to enable GSM only? i have search the manual but cant find any. I have off the data connection in settings->communication, but the 3G sign still appear on the top of home screen. thanks alot!
[Touch Diamond2, Pure General] karaulanov:
Hi XionaxPDA,

I tried the above registry tweak. It does disconnect the data connection after xxx seconds, but the 3G (video call) network is active, it doesn't switch back to GSM. Any clues?
[Touch Diamond2, Pure General] chris10230:
one other thing i find really drains the battery apart from 3G, wifi, calls etc is the actual backlight of the phone, maybe if you started to set it manually rather than on the automatic basis... May help a little.

Hmmm.... with bluetooth enabled I would expect your battery usage would be higher. I also sync my email every 5 minutes... you?
[Touch Diamond2, Pure General] Smackhacker:
No I sync manually only a couple of times per day. But yesterday I played a game that drained my battery 10% or so.

I tried your reg tweak but it will not work. Not good at changing reg settings. I replaced "~GPRS!" with what you wrote, but no go. There is still a "H" instead of a "G" even if I use no data. Do you have your band set to auto?
[Touch Diamond2, Pure General] XionaxPDA:
Ok.. to clarify.

The reg edit will only disconnect your 3g data connection after a timeout of 10 seconds.When a sync tool tries to connect again.. its just uses 3g and hspsa again :)

And a restart of your device is needed.
[Touch Diamond2, Pure General] Smackhacker:
Thanks, that is what I thought. Maybe I am dense and entered in something wrong. I have no sync tool trying to connect and I still have 3g showing up :confused:
[Touch Diamond2, Pure General] XionaxPDA:
It should look like the screenshot attached.

I removed the left 3G icon because i made the screenshot when it was attached to my computer (when attached that 3g icon changes into <> icon)
[Touch Diamond2, Pure General] Smackhacker:
Hmm, I do have that symbol when idle. However, I thought the whole idea was to have GMS as default so that during phone call no 3g connection was used...
[Touch Diamond2, Pure General] shakiraa:
This is unbelievable. A expensive phone like this have such a crap battery life.

Last night i charged my phone before i go to bed. Finish charging at 11pm. After i woke up at 8am, the battery level already at 50%. and the phone usage is at 2.5 hrs already? even i left the phone in standy mode. i disconnected WiFi and data connection.

Can any bro here shed some lights? dont understand how come when i left my phone in standby mode the phone is still using....

Where is the exact battery remaining figure come from? If I go into Settings --> Power, I can see the power bar, and in the Information tab I can see all the info about last charge, usage time etc, but I can't find an exact percent figure. I'm pretty sure I found it once, but I have no idea where.

This is a lot better than my last posting, but then again a haven't used the features I want to.
[Touch Diamond2, Pure General] deechte:
Bro, if your phone has been on for 2,5 hours during the night, something is definitely causing it. It must some software, maybe something with a memory leak, or some kind of reminder that keeps on waking your device up.

This is certainly not normal D2 behaviour. Many people, like myself, have acceptable battery life. I can do two days with it, making some phone calls, some internetting via 3G (which is always connected), some via wifi, app. 1,5 hour of driving in my car with BT and navigation on, without charging.

Hi.

Here are my numbers just before charging.

Standby seems to be really great as though my usage time is in my eyes normal.

I dont use it as a gameboy, nor I use it as an mp3 player. 80 % of my time I am using online stuff (mail with 4 accounts, no push, weather, homebanking, browsing).

Thats it.

Regards Thorsten
[Touch Diamond2, Pure General] Mr-Fly:
This is not true for T-Mobile Germany afaik.

If you have enabled 3G it will use the 3G frequency for the call,

Thats why they give you the different phonetimes on all sites.

English Manual Page 225:

The high 500 hours in WCDMA-Standby are in my eyes under very clinical conditions. Which means, you never loose 3G connect, which in my network is by far not the case. 3G is even lost in buildings a lot earlier than GSM, thats why I use GSM/EDGE all the time. T-Mobile has a nearly 100% Edge coverage anyhow, and the speed is enough for me.

[Touch Diamond2, Pure General] HTC Touch Freak:
I have something intresting here to report. I have been getting aout 1.5 days of usage with my TD2. Much better than my Elfin with the same usage. Talk time is less than 2 hrs usually but I do txt and use internet often.

I'd say typically 4hrs of internet usage and device usage and apps is like another 2 or so for a day. I charge every night BTW. For the first week I would let it completely die before charging.

Any who. What my stats are now are really off. What do you all figure for this?

For some reason this morning my charging status light was yellow. Mebe it was green and I was too tired ut it looked yellow to me. So why is my Last Full charge on Monday. Is that cause that was the last time the battery was completely depleted. I usually have like over 20%-40% left over every night.
[Touch Diamond2, Pure General] guide144:
just want to update my Battery status

Dear all,

I'm Asia D2 user and just use the HTC D2 for a week now. As I've been using PDA for many device (HTC TC, SE X1 and now D2) and I always custom it with many Rom and update those device manytime.....

My D2 was update on the first day after I learn their have Update ROM from Adia HTC web which they said the update only update the RADIO... but I not think so.... it downloaded file is almost 180Mb just like the whole rom update....

My point it I will tell you my battery life story base on new Asia rom not the one come with the D2 when I bourght. My D2 will last long for about 1 day and 6 - 10 hours at MAX before it tell me to charge!

I using my D2 for GPS (Garmin) while I drive to work without in-car charging (about 50 mins for return trip) and using for call about 10 mins a day. Play around with them little... mostly standby...

As far as I can tell, GPS will take my battery fast! follow by Wifi. I live my 3G option on even my country don't have 3G yet (so sad) to see the overall performance.

Hope my info will give you something, I'm myself feel ok! with the D2 battery compare to my friend D1 which normally not last long for a day. I know D2 battery will get better once more rom and Radio update arrive.

i just bought a diamond 2 and i must say this is the best htc device ever so far. really nice design and good interface and it does respond rather fast compared to other devices.

when i did use it the first day.. the battery didnt even hold 1 day - but of course i was using it a lot - playing around and installing apps. now i have charged it and after ~ 24h the battery is on 70%. mostly i had it standby and then it didnt use a lot battery.

my guess is, that the screen itself does use the most battery. its an awesome screen and a kickass resolution and of course that will need a lot power.
[Touch Diamond2, Pure General] gkai:
here is mine:

standby: 45h 12 min

talk time: 51 min

usage: 4h26 min

maybe 15 minutes wifi, no gps, no 3G (only GSM voice, data is de-activated)

33% remaining

I will run it without charge till tomorrow to give a chance to the battery to calibrate: I think the percentage is not so reliable right now: usually it stay at 100% for too long to be true ;-), then go to 40 % probably a little bit too fast, and now it is stuck at 33% for much too long...

So I am pleased with the battery life (it is what I expected, but I'd still like to have a larger battery to be able to use the TD2 to the max (wifi, GPS) and still be comfortable the device will hold for 1+ day. Well, at worst I can buy a second battery for the few time where you are away from the plug for a long time (plane/train/bus travels mainly), really cheap TD2 batteries have surfaced on EBay so it is an easy option. Just waiting to see if higher capacity (more than the stock 1100 MAh) become available...

UPDATE:

here are the stats just before I plug it for charge again :)

battery remaining: 16%/2 bars

standby: 60h 24 min

[Touch Diamond2, Pure General] MarcosC:
mp3 listening - high battery usage ?

Has anyone been using their TD2 to listen to MP3's ? I have the impression that the battery goes down relatively fast in this scenario. Right now I've done a (rather unscientific) test: after one hour listening to music (through the TouchFlo Player), telephone on, screen off, WiFi und Bluetooth off, the remaining battery life went down about 11 %. I'm pretty sure that my old LG KS20 was better than that. Could it be an issue with the HTC player ?

[Touch Diamond2, Pure General] munrobasher:
Battery usage variable

I find the battery life very variable so it must depend upon what you're doing. That said, because it's just a good little device, it's possible I could be spending hours using to read emails, browse etc. so even if it got 2 hours, I'd be impressed.

The biggest drain is Garmin XT satnav which flattens a full battery in 2 hours. Then again, that's not bad IMHO.

since wifi is such a drain on the device anyone tried tweaking it from the

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

I've had a really weird problem with my D2 around power and maybe ActiveSync. ActiveSync is configured to sync with Exchange as it arrives (so called push email) during peak time 8am to 8pm. I usually check my email in the morning before driving to work. On the last two days, there hasn't been any new messages which I know is wrong as I get a couple of backup status messages every night. ActiveSync says "Connecting" but never connects. The mobile wireless signal is okay - H shown about two bars. Status says last connected sometime the previous day (not 8pm).

The battery indicator usually shows about 3/4 - I charge in a cradle at work so it's always pretty charged.

So I powered it off and back on and two things happen:

1. ActiveSync works immediately

2. Battery warning message appears and red LED starts flashing

All very strange. It's possible that two faults are occuring - ActiveSync task is misbehaving thus eating up battery life and this is also causing the battery indicator to not display the real battery life until reboot. Doesn't sound very plausible though does it!
