Significantly improve battery life

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

Battery flat after one night

Yesterday I left the diamond on my desk. This morning it was dead. After some charging I could switch it on and as expected the battery was as flat as it can get. But why?! I'm sure I closed all applications yesterday!
Seems I got an very unreliable phone now... You never know if you can use it some hours later... Not really what I expect of a phone.

Again a new thread which is completely senseless... there are many topics about the battery. Better to find a solution there, than to clog the forum with complaint topics about the same subject over and over again.

mods needed
to clean the diamond threads up...this is just getting silly

Remember to close Data Connections from CommManager. And if you don't use WCDMA, switch band type to GSM (CommManager -> Settings -> Band -> Select your network type). Bad WCDMA-band signal eats battery like lion.

As is your post...
I don't complain about short battery life! Less than one night must be a failure. I already have switched off 3G network and GPRS. I read some of the other battery threads but they didn't help me.
So what else can I do? Something is eating battery - but what?

My post is in one of those useless complaint threads.
Your opening post seems more a complaint than a question. That is not useful. It would have made more sense to post what you have posted now: More information on what you have done so far, as well as ending the post with a question.
When you left the phone in the evening, how many bars were left (I mean the green coloured bars when you are in the energy settings). I have noticed that when there are only 2 bars left, the battery is already almost entirely flat.

How much battery life did it have before you left it on your desk?
I normally have to charge every day, as the battery life falls to approx. 60% after my moderate usage.
but i expect it should last about 1.5 - 2 days if i dont charge it.
ensure you have all the power management settings are enabled in 'advanced config tool' by schaps.
and ensure that you are manually configured to connect onto 2g.

Ok, you're right. I should have posted a question. Sorry for that!
The battery was fully charged. I just took it off the USB cord before going to bed.
3G is completely disabled on my phone.
Perhaps I should leave the device as I did yesterday evening and then watch whats happening. Perhaps an application pops up and drains the battery.
schaps: should one really enable all power management features?! e.g. "sd memory...", "async1..." and so on? They're all disabled on mine. Didn't read something about these options here yet.
Your answers are affirming what I thougt - it's not normal (even for the diamond) that the battery doesn't last a single night.

Hi
i am installed Beepes ROM
3G enabled - Batterie 100% after Night 86%
very nice

Yes 14% for one night would be nice. I have to wait for german roms to appear though...

I have read about some devices popping on when it is exactly 00:00. Not every night, but they've noticed once or so. No clue why it does this... maybe your phone did the same, and didn't go back to standby anymore.
Fully charged it should last 2 days using it for a few calls, sms and email functionality.

Damn... now I know how you feel. At this moment i have over slept almost 2 hours... The phone was 90% full when I went to bed, and empty this morning. No alarm for that matter...
This seems like some sort of bug indeed! Did anyone else have the same problem, and did you find a solution?

Is this maybe due to the google maps-bug? I've read that it doesn't close the gps port properly after use, and therefore the batt-troubles. To tired to find a link.. :/

I've never used Google Maps.
But I had TouchFlo activated. Since I disabled it i didn't have battery problems...

I didn't use the Google Maps either since the last hard reset. As the device wasn't hot all day long, I doubt if it was the GPS being on without me knowing.
However, I do expect it has something to do with one of the communication chips inside (GPS, WiFi, GSM, BT). Yesterday was the first night I have slept with the telephone NOT being in the flight mode. Normally I always use the flight mode so I can sleep without being disturbed. So possibly some 'bug' turns on one of the most draining comm chips for no reason at all.
Ofcourse I could disable the TFL3D, but then I will not know wheter it was really the solution. It might just as well be a one time thing...
@Murks-Muell...
Could this be punishment for me for the first few posts in this thread? Quite a coincidence!

you disabled gprs auto attach?
this feature sucks a lot of battery.
i have tuned my diamond (stock german rom 1.37.407.2) that it needs less 10% over the night (note im only on gsm).

Yep, GPRS auto attach is disabled. Even so, even if it was on, it should not be able to drain the battery that much in one night, especially when nog program is running! I also use the GSM band (not 3G). Any other night my phone uses virtually no energy.

Battery going flat overnight happened to me on ONE occasion.
After recharging and switching on I noticed that the screen never went off, and it seemed that the device had somehow unticked the 'turn off if device is unused for xx seconds' setting.
I figured my device had woken up for some reason (maybe an all day appointment with a reminder that triggered at midnight), then just sat there draining with the screen on.
Ticked the setting, no other changes and I easily get 2 or 3 days normal usage again...

I have had this issue the first night and this morning nearly again. When I wake up and I started Opera to visit a news site and I have read some articles the phone stopped. There was no low battery signal.

your opinion about 2 problems I've read about...

Hi all,
I'm currently the proud (and quite satisfied) owner of an HTC Artemis. The only problem is that the phone keeps hanging more often lately. I think the end of it's lifetime is approaching...
So I'm lokking for another phone. My demands are: GPS & wifi. I'm not looking for a photo-camera that can call, I've got a digital camera for taking photo's. Google told me that the Diamond was the phone for me (I'm very much into graphical stuff, and the g-sensor is just the bomb!). However, when google-ing i've read about 2 issues. I'd like to get your opinions on these:
1. Reception
This is an issue I've found only very little reference to, so it might not be an actual problem. I've read that the reception on the diamond is quite low. I've read that a tester couldn't reach a reception of 5 out of 5 bars, no matter how close or far he was from the GSM-tower. The best he got was 3 bars out of 5. Is this an exception or do you also have this problem?
2. Battery life
OK, this one I've read a lot about. I've read about people whose Diamond gave up after 5 hours just in standby, but I've also read about people who use their Diamond "normally" (thats a very vague term) and who can do that for about 3 days without recharging the battery.
What about your Diamonds. What do you use them for (and how often), and how long does your battery last?
Are there perhaps tweaks that can help to lengthen the battery-life (can 3G be switched off for example, I think that is one of the main power-drains, right?)
Of course, if you have another phone I've missed in my Google-tour, feel free to mention it!

1, I live out in the sticks in the UK and can get full signal on the Orange network without any problems. The 2G and 3G signals are pretty much identical to what I got on my old Tytn so from my experience the reception is not a problem.
2, I've read a lot about the battery life being rubbish on the diamond. I charge overnight every night, but the remaining power at the end of the day is pretty much always more than what I had on my Tytn.
I probably use it for the following daily:
20 mins phone calls
a bit of playing around with GPS but nothing much
up to around 30 mins wifi
data connection usually on all day
an hour or so playing around with the phone apps
at weekends I poll my IMAP server every 15 mins and it doesn't make a lot of difference to the battery.
Right now, it's about an hour before I'll go to bed and I'm still on 50% battery so I don't see much problem with the life. I know it's a lot lower than non pda phones, but if I had a normal phone I'd only be using it for calls from the above list

Reception for me is a little less than my TyTn, but not enough to worry about.
Battery was terrible at first, but has settled down now. I don't think people realise that they probably thrash the battery for the first week or so playing around getting to know the device. Usually I have about 50% charge left after 18 hours so if turned it off at night I could squeeze two days from the phone without charging. Usage wise, pretty much the same as StarMonkey but I browse in Opera for about an hour a day, not with WiFi though.
Battery life might bother some, but if you've had a TyTn or another Smartphone you'll be used to charging more or less every night. This one's no different.

Thanks for your opinions! anybody else who wants to share his or her experience?

As I said, I have an Artemis right now, and I need to recharge twice a week. I don't use bluetooth, and I turn off Wifi or GPRS when I'm not using it. I think that helps with battery-life.

I have no problem with the signal but the battery is much worse than with my Artemis or tytn II. I use tom tom a lot and get 2 hours max on the diamond. Where my Artemis and tytn was over 4 hours. But extra batteries are cheap enough on e-bay.

battery life

i dont know why my battery dies so fast. im upgrading from a sidekick lx which i got about 12 hours of life from to this phone which lasts at max 6. i dont know if its 3g thats making my battery life so low but i know that my sidekick had data on at all times. the thingis i leave a iming program to chat which is called jivetalk. even on a day when my connection is idle, but on, my life is low, i have yet to try to go through a day without 3g on but what is the average battery life you guys get?

The value should be changed to 20000.
You will need some king of registry edit tool to do this. PHM Regedit is a good one and can be downloaded here:

Good Luck

With this registry hack my phone last 2/3 days depending the usage i make

for whatever reason, i do not have that registry value.
I am on ATT using stock ROM if that makes any difference

I do not have this value in the registry, is it possible?

I believe this tweak is only intended for CDMA Diamonds not the GSM variant.
Greets.

bump
according to some posts on the forum, people get over 20 hours of battery life.

my first week of this phone sucked also. I don't remember just how many days it took, but close to a week after purchasing my battery went from 6 hours, mostly standby, to at least 2 days normal usage. (I've never gone more then 48 hours without a charge)
If you've just bought it, wait a week, or as long as you're comfortable, before throwing it against the wall

I changed this reg setting along with a couple other changes (which I'll list later if indeed they end up working). I was getting about 8-10 hours before hitting 10% on my Sprint (CDMA) Diamond with light use.
Well, I charged my phone just past 90% before going to bed last night and left it off the charger all night. This morning after 8 1/2 hours off charger it's at 90%!!! We'll see how it fairs for the rest of the day.

I'm not sure if that registry settings is just for CDMA users , but atleast I created it there myself. Dunno if it works but atleast it feels like my battery is working much better. And of course atleast you should enable all battery tweaks in advanced config. Atm after fully charging my diamond at night, and going to work around 7am. At 8pm or something i have around 70%+ left. It's mainly in standby but also includes some usage, including email update every 30mins (which uses HSDPA).
During the first day I got this (it was used though), i think i had like 60% left after 5hours. Much better now. Also im getting the HTC 1340mA battery today from post, so I'm expecting pretty good battery life with that.
//ive had my phone unplugged now for hours and powerguard says that i have 92% left . Only usage has been the email sync every 30min. Atm .05 radio

I am gonna give this a go

Rapid battery drain (under 7hrs)

Hi all,
over the last 2 weeks i have noticed my diamond getting pretty damn hot on random occasions and really chewing through the battery, i have run task manager when this occurs but no process is shown using alot of CPU.
I have read alot of threads on here descibing similar symptoms, some are just people who have wifi on or using CPU intensive applications, this i expect. But a few other users have described symptoms similar to mine where they are not using the phone and nothing appears to be running.
I am getting the problem with both my original HTC battery and the 3rd party spare i brought.
From reading the board the only definite cure seems to be a hard reset.
What im really after is any suggestions you people may have that can help me determin the actual cause of the problem, for example is their any software that will log CPU usuage over time or other diagnostic ideas.
thanks for your time

checking email regularly?

Maybe you might wanna check if you have the automatic mail checking feature on? Because I noticed that whenever I let my phone automatically look for email quite regularly (i.e. every 5 or 10 mins) it drains more battery then when you set it to check email every 2 hours for instance. Well that's what has helped in my case...hope this helps...

I have looked at my mail settings and my mail checks every 2 hours, i have had it set to 2 hours since i had the device (6 months) but this rapid battery drain has only started occuring in the last 2 weeks.
In that time i have not installed any new software, so am at a loose end as to the cause of the trouble

Hello,
I did had the same symptom : worked really good for 6 months (battery lasted for 30h +-) and in one time, battery was sucked out in 8 ! I did buy a new one (900mah) and it did the same. The only solution I find was to buy the 1350mah (htc) one and from this moment it last more than 2 days without any problem.
Also, I use G-light in place of the standard windows function and from this moment I really had a difference (from BatLog I went from 142mah to 123mah).
Hope it help (yeah I know: buying a bigger battery is not fun but for a device at this price, it's not so much...)

thanks for the feedback, i will order a new battery and give it a try, at the least it will prove if the problem is hardware or software related.
today my phone still has 63% battery since i removed it from charge at 11pm last night. The fact that the problem is intermittent is making it very dificult to diagnose.

Today I noticed my wi-fi drains battery as hell, it was lie 60%+ of battery down in less than 40 minutes. In the past it was like 40% max. The PowerGuard's current meter did not show anything alarming. So the problem seems to be hardware.
Already backed up and hard resetted. The phone is under warranty and so is battery; sending it to service to get it fixed.
Or, I missed something and I can fix it?

Hey,
Yeah I'm currently experiencing the same problem.. I tired just about everything from battery fix cab, radios, to roms. I even got the orginal extended battery. The battery worked really well for like 2 weeks and then it started to drain really fast as well.. My cousin have the same phone as me HTC Diamond, and his battery is verry good.. It can last a whole day with heavy usage no problem. Where as my 1340MAH battery would only lask for 14hrs max with heavy usage, and when we switch the battery same stuff happens... His battery on my phone drains quickly and mine last long on his phone...
So I came to the conclusion that it's definitely a hardware issue.

For those without battery problem, how much usage do you get out of a battery and what kind of things do you do with the phone? I'm just trying to gauge how bad my batter is. It will last about 8-9 hours, but that's with hald of that time spent on the internet on either 3g or edge. I've only had the phone for about a week so it's hard for me to compare it to anything else.

other little things like disabling autobacklight and disabling 3G will help as well.
rgds

One of the things you might want to check is if your phone is constantly trying to switch from 2g to 3g or HSPDA. This constant searching for a "faster" signal can make the phone quite hot and drain the battery quite quickly.
I had it on my diamond when I used to live at my old place as it was right on the edge of a 2g/HSPDA and the phone was constantly trying to get a decent HSPDA signal. The battery would last maybe half a day if I was lucky. Since moving to a decent 3g area, the battery now lasts me a good 2 days on nomal usage. This is with the original battery.

a good tip to save battery power which is something we all have to do, but i do not think its the cause of my new found rapid battery drain.
The last 6 moths i have been getting around a day to day and a half rom the the phone. now on random occasions ot will get real hot (like the gps/wifi is on or like the cpu is flat out) and the power goes in a few hours.
this is fine if its daytime and catch it but a few times its gone from 100% to 0% overnight and i have woken late for work.

interesting, i will leave the phone on 2G for the next few weeks and see if i experiance the rapid drain, maybe i am on the edge of a 2G 3G nexus, as i do get a fairly weak signal here (2 bars 3G and full bars 2G)
thanks for the suggestion

From you last sentance it does sound like it the 2g/3g switching that is cauing your problems.

i have this issue too.
my phone will drain ~5-7% every hour in standby. and when wifi is on it drains 2% every minute even staying on the home screen and me not doing anything on the phone.
from reading this thread, i can see that this is definitely not normal. looks like i'm headed for a dreaded hard reset...

Good day to all. At first sorry form my eanglish/
I have a same problem with diamond. It is overheating while charging at standby (battery temp. is about 50 C), and if it charges by USB, the battery temp is about 46 - 47 C. The phone's fly mode is switch on. HTC service couldn't answer me smth. But it says that same problem have 2 diamond from 1000, and only way to resolve problem is a change of mother board. in Russia it's about 250 euro.
