If anyone can help, I just need to know one thing before I get one of these.
How long does the battery last with direct mail on all the time using a 3G connection.
My Touch keeps it going for 2 days (at a push) on GPRS.
I dont think it can last that long.
I took off from the power source at 9.00 saturday morning and used couple of times for 3G internet browsing, trying configurations, browsing again. And was turned off during saturday evening.
When I back at home, Sunday 19:00, it was 9% left.
Btw, I dont use push mail and not always connected to 3G.
If you dont have GPS/constant GPRS connections active, then I'm fairly sure the life will be respectable once the battery is conditioned.
Currently, under heavy use mine lasts from 9am to about 11pm. The battery has only had three days of charging though, and wont be optimal just yet.
I think thats where the problem is going to be, if direct push keeps the data connection going all the time its going to last about 3 hours, maybe more with the screen off.
Anyone doing this on a daily basis? Its a shame 3G uses so much power, as I said GPRS/direct push can go almost 2 days on my Touch/Elf.
Might have to give this a miss then, which is a shame.
mattpark,
Interesting ... How to make it optimal then?
By fully charging it several times?
Or by connecting it to a power source all the time?
Thanks

The first...
Make sure you always charge the battery completely full (ie till the light comes on green) the first 5 to 10 times...
FULL means charging it double the time it takes for the light to become green. Green light means 90% (although indicators show 100%), and the last 10% takes the double the time to 'squeeze' in there
A battery has to 'set'.... So be sure you to follow this guide
Mt 8525 would last *most* of the day with direct push.
If I spoke on the phone more than a couple hours the batter would be dead or at least turning its self off by 5pm.
I'm wondering if the 8925 will be the same?
I purchased an extended battery which lets me use the phone all day.. but for a 3600 batter that's huge and requires a custom back it only lasts 2 days at best so far. I've been testing 2 weeks.
I may not get an extended battery because this huge backing is anoying and ruins the look of the phone. I love how the kaiser looks and would hate to ruin that. I would get an extended if it fit into the case itself.
Bottom line though I think an extended battery of some sort of absolutely required if you use push mail.. the only question is how long it will last.
Oh balls, Ive just bought one - So thats nokia e65, tytn1, htcs710, htc touch and tytn2 all inside 5 months!!
If you're concerned w/push email and less with web surfing, you can change the band the phone uses to plain GSM (EDGE) and that would allow you to use it for days at a time.
Using 3G/HSDPA, mine lasts from around 7AM to about 3PM with push constantly running and at least 2 hours of web surfing and about 1/2 hour of phone usage.
Hope that helps.
is it possible to disable 3g under configuration settings?, It is not really needed most of the time!
Disabling 3G
Go to Phone, settings, select band, i think choose GSM only, that should do it. There are some apps too that can do this for you on the TYTN.
your battery will go from 8-12 hrs to 24+, and thats w/ push email, i really couldn't care if a 16k email comes in 6 seconds or 2???
do you?
Battery life so far has been okay (only been using for about 2 days). I have direct PUSH activated but I am only using edge. I take a couple of calls per day + 10 min internet browsing. Battery is about 10-15% at 10 pm at night. My day starts around 9 am.
PS- just a reminder to uncheck the "receive incoming beams" in Settings menu if you don't use that function to save some battery life.

There's no infrared support on this device, so I'm not sure if that option does anything. Strange that they kept the .cpl though (had assumed it was accidentally left in the as-yet-unfinished AT&T roms).

If you don't want your data connection open all the time, try installing GBSoft's GPRS & Audio Tweak program. Get it here: http://www.gb-soft.cz/XDAII/product_gprs_tweak_wm5pe_en.htm
You can set it to turn off your GPRS connection every x minutes.

For the first week I was playing with the phone a lot, so battery was draining quickly. But last two days I've got easier, so after ~25 hours since disconnecting charger, I still have 57% battery left.
Generally, I think battery life would be more or less like Hermes' - ~2 days with 3G, and ~3 days with 2G-only.

No, I don't use push e-mail. I've set up automatic e-mail checking every 15 minutes once, tough - but I got rid of it for now, as data connection stays open after checking email, which is not quite nice, regarding battery life...
Can I charge the battery using my old HTC Magician charger?
It has the same input and output (at least from what I read).
The reason that I want to use the HTC Magician charger because I live in NL (charger has 2 legs) and I bought the Kaiser from UK (charger has 3 legs).
Hi all,
just after I had my new Kaiser month agao I was collecting all kind of
software to fit my needs. And short after that I realized - my Kaiser sucks
the battery within hours
A battery tool that shows the temperature and the current showed me:
250 to 350 mA all the time. For a 1300mA/h battery this means 4 to 5 hours
or less.
The other day I removed all installed goodies - and surprise! Sometimes the
current drain was down to 10mA.
To make the story short: remove all timer software.They eat up your battery!
I had installed two of them! One to alert if park-tickets are expired and one
timer to remind me for meetings! Those little bastards apparently run in tight
loops, check the time constantly and use up the most power.
Power consumption is now low as 15mA in idle times.
good luck with your Kaiser / Tilt

Hi!
so this would also apply to alarms set in Outlook for meetings? My meetings are often same time, same people every week, so better to not use alarms for those....
I think my Kaiser needs a charge every 36 hours......

No, I think you'll find he's only referring to third party apps not Windows Mobile functions themselves.
He has a good point. people in other threads have found many fancy Today screen apps (always running) that show memory usage, comms, and battery status are polling the equipment on a regular basis also using lots of battery power.
Thanks Farsquidge!
I will leave my Outlook as it is then !
I think my screen is quite simple as compared with some in the post your today screen thread !

Possibly stating the obvious here but i never knew so here we go...
Change the settings so the data connection is not always on, and only connects when looking for email, web browsing etc.
Its doubled my battery life.
What tool did you use? I'd like to optimize my apps too.

And what battery life are people expecting. I have SPB's GPRS monitor installed and it is claiming I will get a little under 6 hours (which compares to 8 on my Hermes).

I second this. I moved from direct push to polling every 10 minutes, and set the connection to drop after 30 seconds (annoying for browsing the web) and the phone loses less than 2% battery overnight.

Use KaiserTweak. It's in a sticky.
do you have any idea where i could find the individual .cab for this function? rather than using KaiserTweak?
hi,
i tryed to "i guess disable the wifi hardware", and all animations in order to have a greater battery life (with kaiser tweak) , but my phone needs to be charged for 6 to 6 hours...
this phone has a battery problem, for sure, i hope someday, HTC solves this problem....
sorry about the english....
I had an alarm clock to ring every Saturday morning, on for the whole week...I took it off today, following this thread. It appears to have made a huge positive difference in the length of the battery! Many thanks for a good tip.

What alarm application did you use? I'll test it with mine the following days and let you know the result.
I had my office outlook active sync basically "always on". I just switched it to every 10 min during peak and every 30 min off peak. We'll see how much better that goes.
I've definitely noticed that keeping the wifi turned off until necessary helps a lot. I'm using Tmobile here in the US, so no 3G yet. I've been told that 3G sucks battery as well.
3G consumes more power. Use GSM network only.
start -> settings -> Phone -> Band Tab -> Select network type as GSM

FYI, I had to return my Tytn2 yesterday. It lost 100% battery power within 4-5 hours. It was warm to the touch and when charging would become very hot. I put Batterystatus on and it read a draw of 300-400mA when idle. This was also after a Hard reset to check that nothing else I had added to the unit was causing it.
My replacement draws between 20-80mA when idle and 220-250mA when under load i.e. using Wi-Fi, browsing web etc. Battery went from 54% when I got it (1pm) to 26% by the time I went to bed at midnight last night
It sounds like you have a similar problem?
I've set 2 alarm applications to run last night: the alarm in Mortplayer and Pocket Wakeup.
I charged the battery to 100% before I went to sleep. In the morning, after about 6 hours of sleep, my battery meter showed 94%.
This gives an easy calculation of about 1% per hour (with those 2 alarms active).
I don't know if it makes a difference to uninstall the applications or just not using them in terms of battery usage. Anyone an idea?

Is this 'Battery Status' part of an app??? Please let us know as this itself can draw power if it is constantly polling the battery. (Heisenberg principle??)
Hi all,
After 2 days of testing this tweak, I have booked really good results with my Diamond.
The phone has been on and not connected to charger or computer for over 48 hours now, and the battery has dropped only to 50%. That's right, two full days and nights of stand-by time, with an occasional call here and there, a couple of text messages, and reading some email.
Before this tweak I had to charge the Diamond already after 24 hours or less.
So if you have low battery life problems, give this a go:
Advanced config tools -> disable the setting "GPRS auto attach"
Read about this setting here: http://forum.xda-developers.com/showthread.php?t=395301&highlight=GPRS+auto+attach
Have fun and enjoy the longer battery life
But this has been discussed already and is only any good if you don't rely on GPRS a lot throughout the day surely? I mean I use Exchange and I'm sure it wouldn't work for me if I tweaked this setting.
Works great if you dont use the phone all that much but doesnt make much of a difference if you do make calls, send and receive sms texts..email send and receive etc etc.
Ive enabled that tweak and i still find the battery to be utterly rubbish for a phone of this power. Sure it helps conserve some of the battery but i can guarantee you that by 7pm tonight my phone will be dead...like it happened to me yesterday...went to work yesterday battery was 100%...made 3-4 calls...in total spent about 30 mins on the phone...browsed the internet for about 20 mins...sent and received 30 texts...watched a few youtube vids...checked my email a few times...not really heavy usage but by 7pm my phone was dead.
Not impressed with HTC and their monumental screw up with this battery..900mah is just not enough for this device if you want to use it properly that is. You would have thought they would have learned from Nokia when they first released their N95, that had a terrible battery on it as well...although with the n95 8gb the battery is much much better. Why they felt it only needed 900mah is quite beyond me...plus the battery gets hot which proves to me that the battery is not up to the job imo. Luckily the phone is good or else id have sent it back by now...guess ill have to wait for the extended battery to make an appearance. In fact i find the battery so rubbish that ive had to order a spare usb synch cable so i can charge my phone here at work.
Guys, if you want to substantially improve your battery life, go with a newer 1.37 ROM.
The older 1.35 ROM has serious battery life problems, there isn't much you can do about it without to cripple full functionality.
Where can i get the 1.37 ROM?
It isn't available in the e-club on htc.com
It's linked in the Diamond ROM Development forum.
You need to install the developer version of the HardSPL first, then install one of the 1.37 roms - I'm using the official HTC HK-English one with the 1.37.707.1 rom in it.
Works a treat for me - though I haven't had it on long enough to test battery time extensively yet.
I'm on the 1.37 rom, was on the 1.34 with my first unit and the battery is much better. I'm also noticing that the battery improves with 'age'. Plus I've got the dock on the way when it's released so that will help things no end I'm sure. When I'm in the car I shove a normal mini usb cable in from my Sony CD player and of course the upside of that is it will also play my music too instead of using USB drives. At work I use a spare USB and plug it in.
The battery is poo but having worked it in to a routine like that I hardly notice it now.
Unhooked my Diamond last night 22.00-ish from the usb cable and while I am typing now the battery is still more than 80% charged.
Texted alot today, called approx. 30 mins, checked my e-mail several times and played around with google maps for 20 minutes or so.
I did not tweak anything except that I flashed the 1.37 ROM and installed the newest Google-maps thingy.
So I can confirm that the new ROM saves alot of energy and that the battery-life gets better in time sounds also plausible.
With the 1.35 ROM the battery lasted 12 hours max with the same activities.
I've found that after a few days the battery is actually better than it was wen new. Must be that charge/discharging it a few times has helped...

actually I find your usage is a lot. during the day i will make one or two phone calls say 10 minutes. send an average of 5 sms texts and maybe check my email for a minute or 3. what takes most of my battery is when i read an ebook or do a game.

Maybe it is but for me i dont think its that high...as i said my nokia n95 8gb would last a good day or 2 before going completely dead and thats with the sort of usage that i described earlier. Anyways i have a synch cable coming which ill keep at work to charge the Diamond.
hey battery life is better after this tweak. but my 3g logo has changed... it's now in some greyish box... anyone know what this means?
I think this means that the network knows it's available but you haven't attached to the data service. I used to get a similar greying out of the globe icon on my P1i if the net knew it was there but I had unattached manually.
Hi i am novice with my HTC touch diamond & i am also facing the same problem of battery life.
you've shown some solution over there in your post. please, can you tell me where in my phone i need to go to apply this settings.
hank you
This took some hunting down so have documented here in case others are not already aware. The Diamond defaults to leaving 3G/GPRS data connections turned on all the time, once it has connected for the first time since turning the phone on. My battery life was terrible until I changed this to disconnect after 60 seconds - the battery life is now great.
GPRS/3G Auto-Disconnect
Just change 2 registry entries in the following part of the registry (download Resco Explorer if you need a registry editor):
HKEY_LOCAL_MACHINE\Comm\ConnMgr\Planner\Settings\
1) Change the DWORD "CacheTime" to the number of seconds the connection should remain active (I use 60 seconds)
2) Change the String "SuspendResume" from "~GPRS" to "GPRS_bye_if_device_off" (without the quotes).
That's it. This solved all of my battery life issues.
I'll give it a try...thanks for the heads-up
or use diamond tweaks app
Not much good if you use push email though...

Such a useless suggestion...the GPRS connection doesn't have almost any impact on the battery life if the connection is open or not.
Only if data is trasferring it makes a substantial difference, so if you are working with push mail, whatever parameters you change it is useless. Otherwise, if you browse the web like crazy, again - useless.
The battery cunsumption of this device is ****, period. they probably weren't able to stabilize the chipsed properly, since it gets hot every time you activate the display, like gaming or other features unrelated necessarilly with the Radio.
If you are using Push mail, it indeed is a useless suggestion. However, if I'm checking my train schedule in the morning, and don't do anything else except possibly cal with it, is IS a useful suggestion. Not having the connection established IS more battery efficient than not having it on. It's like making an argument that turning the phone or wifi off would NOT save battery life. Yeah, right. By the way, my device does not get hot at all, except when charging.
mmmmh on my O2 Germany branded phone this setting was already set to 60. What is the default Setting on unbranded phones? I want the GPRS Connection to stay on, as my provider charges the traffic in 10kByte steps.
Disconnecting your dataconnection does indeed dramatically improve battery life.

You probably don't use GPS. After 10/20 minutes of GPS with these temperatures outside it does get hot.

They talk about GPRS not GPS if I am wrong.
GPRS does not effect much of the battery.
GPS affects alot of the battery when used.
Grtzzz
I don't see how having GPRS or push email connected all the time and not effecting the battery life. Once you have the connection open the phone/server is constantly sending/receiving packets of data back and forth(syncing) , although minimal if no email is going or coming. Yes it effects battery life big time because its using radio and cpu power. On the other hand GPS i agree it kills the battery life. period.
Thats what I mean normaly the GPRS is sleeping until you decide to go on the internet or look after the weather.
I agree when you use pushmail or other aplications which force the GPRS continuasly to activate its going to cost a lot of battery power.
But when you use it normal to look after the weather sometimes or internet sometimes you can leave it on. It will not drain your battery for life.
Grtzzz
Have to agree with daraj.
The Diamond battery gives me about 2 days of usage between recharges (I don't talk much).
If the GPRS is on (even if I'm doing nothing with the internet connection), on the other hand, the battery last barely 0.5 days.

I have GPRS on all day long, talk in the phone a couple of times a day, listen to FM radio for maybe 20mins/day and use push mail where i get maybe 20-40mail a day.
I have 1½-2 day on a fully charged battery with my Diamond. I dont find that too bad - actually a lot like my old HTC Trinity.
Battery life too bad
I had Diamond for a week. Battery life is just crap to a stage I am afraid to use it. Initially I thought that I was playing around with it thats why the battery is draining. But today I was doing a 13 hour shift I hardly used the phone except making 3 calls lasting couple of minutes each. Battery was full in the morning - charged at night. By the end of the shift the battery was down to 10-20 percent!! I was so shocked to see this. Without even using the phone, the battery just drains, I dont know why. So, disappointed with it now

God dam it this is the worst phone ive had, even my old n95 lasted longer than this.
All ive done today was a little Wlm, sent 11 txt called about 4 times only afew mins. Mind you i did test out the gps with tomtom but that was a 5 min drive down the road. Ive had to charge it 3 dam times today.
I cant wait for my genuine extend battery to turn up.

I've had the phone for over a week now and to call the battery life good would be an overstatement. It is however adequate. I talk on average 1-2 hours (3G only), use poll mail (30 minute check intervals), use the browser and GPS for perhaps an average 20-30 minutes per day. At the end of the day I usually have 50-60% of the battery left. When left in standby with just the email checking, it consumes little.
Only once did I get excessive battery usage and it's an incident I can't explain. I left it overnight in standby with no programs running and the battery level dropped from full charge to 50% in the morning. It hasn't happened since.
In fact, while the battery life certainly has been inferior to my previous phone (Nokia 6210) it's much better than on my last WM phone (Mio A701). After having read reviews and user opinions I expected it to be worse. It's not good, but it is hardly disastrous.
Since two weeks i have officaly upgraded my HD7 Firmware to the latest one with Internet Sharing. Since this date, my battery life is very short. Before the Update and with 100% Battery Power, i have 1 Day, 9 hours Time, after the Update with the same Battery Level only 16 -18 Hours.
Today i have downgraded to the last state via Zune an voila, now i have again 1 Day, 9 Hours remaining time with 97% Battery Level.
For some minutes i have written a mail to HTC Support and will wait for a response. Can anyone here report the same problem?

Hello bilbo_b,
I seem to be experiencing the same problem as you are. And I have been searching everywhere for an explanation for this problem. I think it is really more of a software bug showing the correct/wrong values (at the moment i don't know which is showing the right values). Before the update, it was showing as mentioned, 1 day and xxx amount of hours. However, I found that it is not really accurate because it seems like although the values shown are different, I am actually having the same amount of uptime.
Has HTC replied you?
Regards,
Jiesen
Yes, they have replied, but not es expected. The supporter means, that there are new features in this new firmware and i must live with a little cheaper akku load. thats a shame. that are 15hours difference, thats not a short time of some minutes or one hour!. Again i have replyed to the support mail, that im not exited about the situation. the next response was a mail with some energy saving tips (disable WLAN, disable GPS and so on...). There was now a direct response, that they will investigate in to the problem. Thats the actual state since yesterday evening 6:00 pm German standard time.
what i can say is: it is not only a bug showing incorrect values. it seems that the showed times are most correct. my device has a real shorter life per day with the FW Update. I will wait now for new response from HTC.
I see...Seems like the only way to have longer battery life is to do nothing on the phone. If that's the case, then why have all those features right? LOL. I did try to talk to the customer service of HTC too. They told me to try a battery test i.e. turn off all services (turning on airplane mode), turn off all syncs etc. change the display to BRIGHTEST and screen lock to NEVER, from a full charge. If the battery goes below 60%, I am supposed to send in my device for a repair.
I have done that and it did not go below 60% but close. I guess that just rules out the possibility that it is a hardware issue. However, it does not really explain our problem here. . Looking forward to your updates! thanks bilbo_b
After getting no wise answer from HTC, i have updated my HD7 again. This time the 7740 Update and the HTC FW Update together (last time the 7740 was not available, only the FW). After Updating (which takes some more time as before) my battery was 100% and i have 1 Day and 11 hours remaining. i will see what going on the next days. i will watch this.
I gave up and finally decided to flash a custom rom. I have also just started using anker battery with a 1300mah capacity. I will let you know how it goes.
The battery works at the moment. all is fine. i hope this is now permanent. i will watch it further.
Edit 1: After 1 Recharge, i have 1 day and 15 hours remaining. the last charge was going down to 9% after 1 Day and 14 hours with normal use. great so far. today i will try internet sharing and will look at the battery again.
PS: normal use is: some surfing via WLAN, some surfing via GPRS at a high speed train. normal EMail via Exchange Push service, using of GPS, calls, SMS and so on. there was a 7 hours trip with a highspeed train and fast changing phone cells within this charge.
I got the internet sharing / HTC firmware update a few weeks ago and immediately it was very noticeable that, without changing my habits at all, the battery was lasting only about 50-60%% of what it used to. I used to never have to charge the phone in the middle of the day and would usually make it to 11pm no problem before having to charge. However in the last few weeks I was finding the battery dying at about 3 or 4pm, unless I started charging. I have spare batteries and these made no difference.
However, the 7740 update arrived for me last week and the battery is back to pre-internet-sharing levels; I once again make it through an entire day (unless I've been using internet sharing for a few hours; that does obviously use up a fair bit of battery). So obviously something was fixed by someone in that 7740 update, even though I've seen no announcements or change logs to confirm this.
