Found a way to extend my battery life, weird though

I was just wondering if someone can test it out as well. Ok my situation is that I used to put my phone in standby with nothing on such as my phone looking for email every so minutes because I set those to manual. Don't have any programs running as well. Well when I would wake up my phone the battery would be drained substantially. Example of this was I had my phone at 100 percent charge, went to bed and when I woke up my phone wouldn't wake up so I popped out the battery, put it back in and 28 percent battery. I was like wtf I'm not even using my phone. Well I noticed that if I turn on my bluetooth the battery does not drain like it does when it's off. Kind of weird but I've tested this out and it works. I am using Shaps: 4.31 ROM English and Radio: 1.27.15.32 (I remember reading that this radio was a BETA but I've been using it for almost 2 months maybe more) I'm thinking about switching my radio for another one. Just wanted to let you guys know it's weird. I find myself keeping my bluetooth on all the time so the battery doesn't drain as fast. I can actually get a full days use of my phone now. Weird huh?

Yup - weird - I find exactly the opposite. I turn off my bluetooth when I do not specifically need it to SAVE my bettery.

I have an even different situation. Since I constantly use my bluetooth headset, I leave Bluetooth in the "On" mode all day and night. The thing is, I charged my battery until it was at 100%, left it on the counter (not charging) for the night (approx. 8-9 hours) and when I woke up, it was at 98%!
Keep in mind, Bluetooth and WiFi were both turned on. Good stuff.

Commas are your friend.
As it is, it's barely readable.

If your battery is draining over night when your not using it, it's probably because you have something running in the background. You might have "closed" something and then it was actually still running. Try installing AlltheWay's task manager. This aids in making sure nothing is running in the background.
I'd upload the cab but I'm at work and don't have it.
Getting a full days use out of your phone is NOT something you should be happy about. I get 2 days with Wifi and Bluetooth use.
@ kamilzmielca: Your Wifi connection goes to sleep when your phone does, so your Wifi actually wasn't running over night.

yeap, mine does the same thing, thought i was crazy, but with bluetooth on i save battery life.

Yeah man I thought I was going crazy also. To the previous poster all the programs are fully shut down. I've had many pda's (windows) and I am familiar with how they work. I fully shut everything down and then put it to sleep. Bluetooth seems to be extending my battery. Like I said before all my email I have setup in the phone I set so I manually have to send/receive instead of it looking for it at a predestined time. Nothing is automatically connecting (as in programs) I'll look a little deeper, it may be due to the radio version on my Kaiser. Any input on this guys?

you could try to measure the actual battery usage with "BatteryStatus" with and without bluetooth. Would be interesting to see the differences.

Maybe the bluetooth is slowly charging the phone when on through the radio waves! or some mad theory
I might give this a try as my phones lasts about a day atm

My phone lasts about a day at the most with full battery charge. 2 hour of talk time plus the other stuff I usually do. 2 days is crazy maybe you don't have as much programs on your phone so you use it less. (to the previous poster) I will get that battery program and do a test to see the difference.

another crazy idiot here: bluetooth on also gives me a longer battery life...
is this a joke from HCT??????

Your not crazy man! I'm doing a test now with BatteryStatus and notice that I actually get a lower mA reading with BT on. This is messed up.
When I fist read this thread I though everyone was nuts, now I think I've just entered the rubber room. lol

I could imagine, that some application or some part of the operation system is trying to communicate with the bluetooth stack. And when bluetooth is turned of, it tries it again and again. Where when bluetooth is turned on it justs recognizes, that bluetooth is on but no device is paired and doesn't bother any more.
Just an Idea. But it would be interesting to find out if this also happens with an absolutely clean device after hardreset. And if so, if this applys to all ROMs.

I mentioned in another thread, but I installed that new Google Search bar that came out the other day. It sits on your Today Page. Battery life went to heck when it was active. As soon as I disabled it, battery life improved. I'll try turning on BT. You never know.

Just an update.
I've flashed duttys new release (in my sig) and the mA reading is where its supposed to be (between 1-5) WITHOUT having bluetooth running. I'll test with BT on for a little and post back.
EDIT: With BT on I seem to have the same power drain as I would normally.... which is great cuz I usuall leave it on anyway.

This BT phenomena might have something to do with the flashed ROM you guys are using. I've got the standard HTC TyTN2 default ROM and BT on definitely sucks battery power more than without.

Very strange. I could even see it being possible...
With bluetooth on in standby it's doing sub-10mA (5-8mA). With the screen on, it's about 80mA to 100mA.
With bluetooth off in standby it's doing sub-10 again... maybe a little lower.... and with the screen on... still around 80mA.
Doesn't seem to be having the desired effect on my phone (stock O2 ROM), but then I can already get 2 days out of my phone without too many problems.

Now it only saves my battery granted if I'm not using a bluetooth headset. If i'm using bluetooth like via a headset it will drain fast. If I have it on but not using any Bluetooth devices it saves my battery.

Bluetooth on... wtf??
Hi all
... unbelievable, i test this on my device too, and i can confirm -> Bluetooth On (but not using it) saves my battery!!!
Info:
WM6 Pro CE 5.2.1620 (Build 18125.0.4.2)
ROM: 1.56.408.5
Radio: 1.27.12.11
It could be added to the Wiki!!!

Battery Problem

Had my HTC Diamond (Orange) around a week now using the ROM that came with it, 1.37.405.1.WWE.
I cant get the battery to last more than 8 hours, on average it lasts 6/7 hours! I am charging it overnight around 12 hours and all bars are full at the start but it drains so fast.
I have turned off 3G, bluetooth, wifi etc... set backlight to go off automatically, generally i have it locked so backlight is dimmed most of the time.
I am not making any calls or even sending texts or actually doing anything, its just laid on my desk while im at work, so who knows how long it would last if i did!
Do you think i have a dodgy battery? i dont fancy sending it back to orange with their stock problems. Would a new battery solve the issue? ROM update? or could it even be a dodgy handset? cheers. J

Well it's a normal lifetime for the Diamond...
(It's a joke...)
If what you sayed is true, there is 3 possibilities :
1) You don't have any network coverage so the diamond is seeking for one and that will drain your battery quickly... (but not sure such quickly..)
2) You're battery is dead ?
3) You'd installed an application that drain your battery.. try a hardreset to see....

I'll try a hard reset.
I'm making sure no apps are open also, Task Manager is empty. Could there be anything else running secretly in the background.
I've seen the stories of bad battery life, but 6/7 hours just seems ridiculous considering im not even using the phone, just leaving it in a state of unlocked...

I have had my Diamond for about a month now, and had been suffering from most of the usual battery issues, I am running Dutty;s Project V2 rom
A few days ago I downgraded to the .05 radio and this seems to have cured the battery issue, I do turn off bluetooth and 3G when I dont need them.
This does seem to have cured things nicely, looks like the phone will last 2 days or so
Bloke

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?

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

Excessive battery drain during phone calls...

i have searched on the forum and found no one with the same symptoms that i am experiencing. i have had my kaiser for about a year now and have been happy for the most part with battery consumption. but about 2 weeks ago my battery started draining super fast when i'm talking on the phone. even with a bluetooth and the screen off. i don't remember changing any settings at all. for a 10 min phone conversation i can use 25% or more of my battery. i purchased a cheap extended battery a few months ago and i get the same results regardless of which battery i use. i purchased the phone with WM6.5 pro from PDACorner/ abusalza (ROM version: PC.Ultimate.V17 WWE)already installed. i really like the ROM and all the apps installed and i'm not reall excited about flashing a new ROM. any help will be greatly appreciated.

Could be that both batteries are bad.

My battery started to drain very quickly last June, so in Sept. I bought a new battery,( cheap one, on line ) worked great. I used both batteries back and forth to make sure that I always had a fully charged battery.
Last Dec. My phone started turning off for no reason, ( like the battery was dead ) so I stopped using the old battery and just used the " new one ". About a week later my phone went into a start up; reset loop. It would not boot without resetting. I figured the battery was old 3 months old, it couldn't be the battery. I tried everything else short of buying a new phone. Finally I went on line and bought another cheap battery. The phone has worked perfect ever since.
Moral of the story ? Don't discount the battery just because it still seems new. I got what I paid for from my $12 battery, a little over three months.

that all makes sense, but the battery only drains this fast when i'm on the phone. nothing else; wifi, movies, even gps drains as fast as using the phone...

Same issue here..
Strange thing is that when on the phone battery is draining very fast and most of the time the call is cut off. When I start the phone again I still have power and can work on my phone, when I try to make another phone call the phone cuts off in one second. I hear about to batteries, where is the other one and can I replace it?

Well if you have a custom rom on the phone the radio might need to be changed.

Very true, try running the stock radio for your device/carrier and see if you get the same results. For me personally I've noticed a difference in battery usage especially during calls depending on the radio. For me on AT&T in the US the original radio seems the best.
