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

Problem: very weak battery, even for the diamond!

Hello guys!
It's nearlly my first posting here, but i'm reading this forum for quite a while now.
I finally got an Xda diamond and everything was ok the first couple of days, even the battery was satisfying. When i use it really much, the battery lasts for about a day, that's ok. But 2 days ago, suddenly the battery got empty from 100% down to 0% in 7 hours, although i did not use the phone much. I had a call for about an hour and that's it.
Knowing there are some possibilities to save energy, i followed some advice from this forum:
- took down the display light to stage 2
- switched off UMTS
- switched off GPS
- installed powermanagement.cab
- switched off RSS Hub auto-download
- made sure there are no applications running in the background all day
- made sure there are no data-connections like Bluetooth or GPRS running all day
I also installed PowerGuard v1.2 which told me, my Diamond drains about 65 mA, what seems to be a proper value, comparing to other peoples around here.
This morning i took the Diamond off the charging cable at 8:00 and it switched off at 16:00. I only used it for a 1 hour phone call again, thats all. I did not do anything else with it.
I don't unterstand, why it lasted much longer the first couple of days. Anybody have an idea?
Thx so far!

1. Check with Task Manager Cpu proccess
2. Hard Restet ?

I have the same problem AND additionally sudden softresets.
The battery is defect. I will buy a new one and o2 will refund the money.

The battery is not supposed to get empty to anywhere near 0%, it can be damaged if it does. The phone is supposed to turn off to prevent that happening.
If killing tasks does not help, maybe you just got a bad battery? Edit: ^^^ What he said!
Here's a useful link for information on Li-ion batteries: http://www.batteryuniversity.com/parttwo-34.htm

Hi!
I recently found the solution. My sim-card was too old! I had been using it for about 4 years. A couple of days ago, I ordered a new one from my provider (O2 Germany) for free. Since I changed the sim-card, I never had any problems with the battery anymore.
Why didn't I find this advice anywhere?
Cheers

Your SIM card was "too old"? My technical prowess is nothing to brag about, but even I can tell you that that could hardly have been the cause.

Older Sims seem to drain more battery power...

I have to agree with H3x ... I don't see how a SIM card would have any effect on battery life.
As a point of reference, I'm very satisfied with my battery life. I charge it for an hour or two a couple times a week. I am diligent about turning off WiFi, Bluetooth, and running apps when not in use, but other than that I don't do anything special.

With GSM band manually selected in phone options and moderate use, my diamond can last over 2 days, with "auto" band selection it barely lasts a day...it just drains stock battery so much, even in standby...but I still can't be happier with my device, no matter what
Decided to watch battery more carefully over PowerGuard, some things started to make more sense...

Yeah, I have that selected too, so I'm sure that helps. Maybe the OP should try it?

Overheating and abnormal battery consumption!

Hello, I am new to this forum but it seems like the right place to post this.
I did some searching on this forum and I saw that I was not the only one with this problem, however I did not find any answers to the posts regarding this. I am hoping some suggestions will show up in this thread though
My Diamond has been acting very strange for about a week now. All of a sudden, my batterytime decreased from a (for me) normal time of about two days, to about 30 minutes. Also the bottom part of the phone gets really hot.
What's even more strange is that two days ago it somehow just went back to being fine?! Today it's back to it's weird hot/battery devouring state.
ROM-version: 1.37.413.3 SVE (Yes, I know I should update it...)
Radioversion: 1.00.25.03
PowerGuard says:
Battery Current: -324 mA
Battery Voltage: 3542 mV
Battery Temp: 38,9 C
I also have a few applications installed, like the answerkeys disabler app and G-alarm. But other than that it's pretty much stock.
Has anyone heard about this before? I don't really like the idea of sending it in for repair since it's about 10 days without my precious phone =)
Any suggestions greatly appreciated!

i have read on here before that it sometimes is fixed (or reduced) by updating the Radio.
i believe the BS14 radio is the best one for reducing heat and improving battery life.

I have had a similar experience....a day or better battery life has been norm for a month, until the other day when I noticed my phone was very warm/hot and had burned an abmormally high perentage of the battery life in two hours. I also had one occurrence where instead of the normal 7-8% overnight burn, it had used 70% of the battery life. I'm still trying to see if I can catch the culprit; some sort of latch up of the hardware or a program not behaving.
Let us know if your problem does go away with a different radio. I have a stock US GSM and am happy with the radio performance...(unless it's eating my battery when I'm not looking.

Ah, so I'm not alone then!
I have not yet had the time to try this as I have been working too much, but I will try updating the radioversion before I buy a new battery or something, that's for sure...
I'll post in this thread with results when I'm done!
By the way, if I upgrade my ROM, will that also update the radioversion?

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.

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.

And one more notice, which battery temp is 46 or 47 C, charging automaticaly switched off... Phone heating, but battery is not charging !!!

i've resolve problem...but don't know how i did it. I try to recharging stock acc. while 4 or 5 cicles, and today i have workable Diamond.
not discharge
not overheating
it's so strange, but it works

Battery Life hacks? Which one?

Hi,
I came across this cab file today for the Kaiser http://forum.xda-developers.com/showpost.php?p=2132767&postcount=151
its right said:
ok guys, some of you want to increase the battery life, i attached a cab file which contains these registries:
[HKEY_LOCAL_MACHINE\Comm\L2TP1\Parms]
"DisablePowerManagement"=dword:0
[HKEY_LOCAL_MACHINE\Comm\Irsir1\Parms]
"DisablePowerManagement"=dword:0
[HKEY_LOCAL_MACHINE\Comm\AsyncMac1\Parms]
"DisablePowerManagement"=dword:0
[HKEY_LOCAL_MACHINE\Comm\PPTP1\Parms]
"DisablePowerManagement"=dword:0
[HKEY_LOCAL_MACHINE\Comm\L2TP1\Parms]
"DisablePowerManagement"=dword:0
all of these can improve the battery life, but if you face any issues with WiFi, just check these registries .
enjoy.

I have spent about an hour trolling through all sorts of posts and would like any feedback on what is recommended.
Thanks in advance.

anyone have any comments? surely im not the only one trying to get a full day out of the stock battery.

This is the best hack out there.
http://cgi.ebay.com/AT-T-TILT-8925-...s?hash=item1c05a465c2&_trksid=p3286.m20.l1116

if I not wrong, sp call battery hack ..it not really hack to battery, It only reduce the phone keep searching the network (which consume a lot battery ...according to some forum).
I think this one better ..2800mah ...
http://www.lelong.com.my/Auc/List/2...00-110-120-O2-XDA-Stellar-2800mAh-Battery.htm

My phone will last about 3 days by measurement if I'm not running Flexmail with two mailboxes online. Otherwise, 14 hours.
Want a full day out of your Tilt? Limit network activities, or interactive activities, and don't use the GPS. Network, backlight, and GPS are probably the biggest power users on the Tilt. I assume WiFi too, but the only thing I've used WiFi on my Tilt is for scanning for open access points.

Sorry bumping thread couple of months old....
I've got a Kaiser HTC TyTN II and my battery is a shame.... i can't get it until the end of the day, always getting empty at the end of the day....
What can i do to improve the battery life time?
I've installed those cabs, but nothing really happens....
My phone idle during the night takes like 20-25% of the total battery.
I just use my phone to make and receive calls (lot of them), and sometimes the bluetooth when staying at the car.
Some time ago i ordered a 2800mah battery, but i really don't want to carry always a replacement battery with me, besides its really heavy and big....
Thank you for you advices.

There's an old saying begars can't be choosers... Kinda makes sense you want better battery life yet you want to stick to stock battery.
Ummmm? Buy a OEM new stock battery if the size of 2800 is too much? To be honest the Tilt is a brick anyway so i'm happy to have aprx 1cm added to the base... Also maybe time to try all the Radio's available to see if you can get better battery life, while @ it hard-reset device to start from fresh
