Battery Drain on XDA II

Hi,
I have a very recently purchased XDA II.
I was under the impression that the battery time was considerably improved.
Although I have turned down the backlight brightness when on battery power, it still starts to loose power when I receive or send a SMS for example.
Is this normal or do I have a duff battery ?
Steve

try turning off bluetooth when you dont use it
it's suppose to be a batt hog

Yup,
done that. I only have BT on when I am actually using my headset.
Any other idea's
Steve

when does it auto turn off ?
when does the backlight turn off ?
are there any SD cards connected seem to recall that they eat batt aswell

I've had mine a week, have the same power drain problem. After charging it all last night I managed to use it as a PDA for a total of 40 mins over a 6 hour period today before the battery drained. No phone calls were made, Bluetooth disconnected (I do have a 256 MB card installed, but I don't know if this has anything to do with it), furthermore the backlight is set to the default setting and the auto power off set to 1 min. In any case I would expect to get more than 40 mins use of the PDA, the specification states upto 15 hours.
I took the unit back to the store, they say that this is a rare problem (yeah right :roll: ), they gave me a new battery which I am now recharging, hopefully this will work.

mmmm, it's very strange.
I am doing a test now. I have a imate with the official imate upgrade. I have a gps sysonchip bt. One and half hours ago i connected the imate with the gps and i started a demo of 500 km. Now the battery is at 75%.....Maybe de last upgrade solved this problem.... :shock:

You should get far better performance than this.
Three things that can drain the power:
Communications/Peripherals - IR, bluetooth, SDIO wireless LAN etc. Disable all of them unless you're actually using them.
Processor hungry programs - check if you have anything running in the background that could prevent the device switching to full sleep mode.
Lack of radio signal - if you're out of contact with a base station, the device tries to connect at full power every 30s - a big battery drain, so if you know you're out of contact, turn off the radio.
However, even with everything running, I'd expect a running time way above 40mins, so it sounds like you have a hardware problem with your device. I easily get 3h full brightness, full processing (ie watching a movie or playing a game) with radio on.

Turn IR off?
Is there anyway to actually turn the IR off on the XDA II?

Just the Start-Settings-Connections-Beam-Receive all incoming beams checkbox.

tried the new battery today, same procedure as yesterday (no bluetooth etc), had a slightly better performance today from the new battery, managed to get roughly an hours actual use out of the PDA (games etc) over a period of... 10 hours, ooh atleast it lasted the working day so must be better... however still no way near the 15 hours PDA work time as stated on the box!
However something I have noticed is that every now and then (after switching off the unit and just leaving it on the desk) the screen comes to life displaying a running program, (just how do you turn off the media player? I now realise it isnt with the "X"). Anyway why does it "power" back up? I wonder if this has anything to do with my power problem, that perhaps it has switched back on whilst in my pocket (BTW I have set the buttons so that they do not switch the PDA on accidently)
So, I'm recharging again, (I think I might take the MMC card out see if tht makes a difference). I expect something better for my EUR 500, what is the point of being able to go online anywhere if you have to be plugged into the mains! If I can't get the damn thing to work satisfactoraily by next week then it is going back to the shop, despite it being a Gucci shiny piece of kit!

@MoistVelvet: Actually, it;s not so much the device itself but the operating systems that is the cause of a few quirks. Luckily, a lot has been written on this forum and other forums on websites such as www.ppcw.net. A lot can been improved by limiting the number of programs that can be found in the \windows\startup folder of the XDA II. I'd suggest you have a look around in the various topics. I ended up honing my XDA II to a point where I am actually very very satisfied with it's performance ...

Can someone repost the items in the windows start up folder than can be deleted and what they do on the XDA II.
I was surprised at the amount of apps in there, but dont know what I can safely delete.
Steve

Wiz,
thanks for the tip, I'll have a look around.
Well the batery did last longer yesterday, managed to get through a whole workig day before it ran out, so the jury is still out!
Realised perhaps one of the reasons why the unit would switch itself on, whilst at work I have a very low signal, so every minute or two the signal strength would go up and switch the screen on. I have set to auto switch off after 1 min, but I wonder if there is there a way to stop it from switching on?

Hm, my experience is quite different. I use it throughout the day with around 15 phone calls, at least 2 GPRS synchronisations, some other usage of contacts, calendar and email and when I get home it's still around 60 percent - the most drain appears to happen on the way back home when I use the BT headset...
When your uses so much more power you may like to check what kind of programs you use. First idea is to have a critical look at fancy today plugins... my worst experience was with Battery Pack, the best way to empty your battery :lol:
Maybe you like to use UpTime plugin (http://ae.inc.ru/uptime_t.html) which really tells you how much you actually use the PocketPC and which doesn't do anythings while it's switched off...

Actually, the reason it periodically switches on is the O2 Homezone application. Whenever your phone changes to a new base station (which can happen even if you don't move), the stupid Homezone app turns the phone on. This is a known issue, and the only known remedy is to disable the app completely (remove from Autostart folder, soft reset phone).

Hi
I have an xdaII, which i load loads and loads of things onto. I did find that the battery was draining quite quickly. eg. charge it all night, just leaving it running in the day with hardly any use would drain the battery by about 90 percent! Bluetooth was off etc.
One time, the thing drained completely, and it needed a hardboot. Im going to send it back shortly for investigation/repairs.
However, since it hardbooted, i have not installed a thing. And i am finding that the battery is lasting a lot longer. I managed to go 3 days, of average usage, (few incoming/outgoing calls), without charging the battery!
This makes me think some apps must cause the battery to drain. I had battery app installed (that runs in today screen). I had fonix voicedial installed. I had quite a few games installed.
I think some software was causing the battery consumption,.. possibly battery pack.

re
I have previously had problems with battery drain, due to apps running in the background.
I also found specific apps like the battery pack, LAN sdio, bluetooth and the camera app, would drain the battery quickly.
Although you can manage closing apps down through settings/system/memory/running programmes I found the app Gigatask http://gigatask.com/ a simpler way to manage tasks.
There are others, but I found this suitable for my needs.
Now when I close an app I know it's closed and not running in the background draining the battery.
I still charge daily, habit now when I get home from work, but I have no worries about battery drain, and it rarely goes lower than 65% for a normal days use.
Cheers, Shire

turning infrared beam recieve off will help a little

Average Battery Life on T-mobile Wing

I was just wondering what is the average time of battery life on your wing..mines is currently about 10 hours idle but while im using it that goes down to about 5 or 4 i just wanted to know what is the average before i call t-mobile and ask for a new battery.

A few of us here have been having problems with the battery actually. When I first got the phone, I left it clean and stock. I would do a lot of texting, make a couple phone calls, and play a few games here and there. From 7am to 1am, I would go from 100% to about 54% (18 hours of usage). Now, if I leave my phone idle for 2 hours, my battery drops down from 100% to 80%... I can't even go a full day without needing to charge the darn thing. 200 hour idle time my arse!
But personally, I don't think it's a problem with the battery... The phone is doing something in the background which is causing a massive battery drain. Right now, I'm testing my phone to see if I still suffer the same drain while in flight mode. I'll post the results HERE in about an hour from now.

The longest the battery can last is 1 week...
On a full charge, you can talk for 5 hours...
the more features you use, the more power it'll consume.. if you do a lot of internet browsing, I believe I saw GPRS Data connections use more power then WiFi.. so use wifi when available ...
also, be sure to regularly check your phone's task manager before setting it aside for long periods of time... sometimes it can be hard to notice the camera, text/mms, calender, Internet Explorer, Windows Media Player, are all running in the background while you're at the home screen...
My wing usually lasts me from unplug at 8am until plugin at midnight... power usage always varies a lot as... as you can tell.. the data connections use a lot of power... and if wifi isn't available, it uses at least 30% more power doing a GPRS Transfer -- based on the initial information i've read about the issue.

I noticed Bluetooth and WiFi taking more battery than GPRS

As long as I plug it in while I am at work to a USB cable, I don't seem to have any battery problems. I use GPRS and SMS constantly.

I spend the whole day on the phone ... between texting and I receive all my work email directly to my phone... so I'm on it various times during the hour... and it seems the battery drain is huge.
all I have done is turn the screen brightness down whenever I'm not using it, and have the dynamic overclocking on, so the processor goes down whenever its not in use ... but I still think the battery drain on the wing is ridiculous.

Well david, overclocking doesnt help
Im clocked at 247mhz, i can make it last about 24 hours using it here and there. calls about once a hour for 5 min or less, texting through the day, and occasional wifi use. at stock clock speeds, it lasted about a day and a half, but it all depends how much you use it

At 1st i thought the battery darin was rediculous as well but when u think about it when u use it the battery goes down about 8 times as fast( depensing on what ur actually doing w/ it.
Now i charge it at night and go to school with fully loaded battery 6AM, i text all the time and when i get home its around 85% 2:30PM, use it occasionally and at the end of the day after at least 3 hours of talk time its on around 30-20% i could last w/o charging it but i charge it overnight to full, with NORMAL use and not talking for about 4 hours per day so far its lasted 4 days for me. could have made it to 6 but i wanted to showoof my new phone to my friend
so battery life is not that bad just depends how much u use it, Also if ur listening to music just turn off the screen and thats a REAL battery saver. also press the power button when on the phone and etc.

Wing Battery Drain
I have improved my Wing battery drain by doing the following...
- Turn off the automatic weather update on the Today Plug-in
- Check my emails manually (do send receive when I am ready to read)
- Suspend device when not in use - need to use device lock app.
- Update ROM to PDA Viet v 14 (thanks to easy instructions from David)
With the new ROM and the device locked - even the accidental press of any of the face buttons (when phone is in pocket) turns the device back on - even though the screen remains locked (due the Device lock app). Is there any way to suspend the device completely so can only be turned on by hitting the power button only? I would still want to receive / answer calls etc. without having to hit the power button....

Go to settings, Lock ... and there is an option to lock all buttons except the power button when device is powered down.

I am trying to fix my sisters Wing (I have a Wizard). I have tried disabling background programs, as well as setting things to be more gentle on power usage, and still she loses battery like crazy. I know the Wizard had some battery drain issues with certain WM6 cooked roms, and a cab fix helped. Does anyone have a cab fix for the Wing? Also, reading in this forum section, it seems that the Wing doesn't always disable background programs. Would you suggest a third party task manager to "pick up the slack" or does it not matter, due to the nature of the winged beast?
I appreciate any suggestions. While I am new to the Herald, I am "old hat" on the Wizard, so I do have a general understanding of how the HTC devices work.
Thank you in advance.

I have read a lot of bad stuff about battery life with every rom except the OME t-mo. I had the PDA viet and battery life was terrible, With the stock rom it is at least 4x longer.

hello ive the same problem with the last 4 wings ive and ever since ive switch from the stock Tmo OS and upgraded to the TouchFlo OS, Ive noticed a huge differnce with the battery life even overclocked
If your will to taking the risk ide say go for it, i jus started messing around with rom and i got say its a big improvment from the original wing which i was ready to throw against a wall!!

I have Touch Flo on my Wing, and if I charge it to capacity I usually only need to do so it every other day so long as I don't play any NES games on it. I keep the wifi off if I'm not using it of course. I have it dynamically stepping the CPU in a range from 100mhz to 234mhz. It really seems to help extend the battery for me, while still giving it the tiny extra kick it needs to run nes and sms games.
My wife has the official wm6 rom on hers, but is also dynamically overclocked as mine is. She needs to charge hers nightly, BUT she also plays solitaire and bubble breaker daily.
Overall it's on par for battery life with my prior motorola phone, which I never used for anything but regular phone calls. With that in mind I'm not necessarily impressed, but am definitely content with it.

I've had HORRIBLE battery life and AWESOME battery life, all within the same week. lol
There was a problem I had at one time, where filesys.exe would take over all the CPU and kill my battery.
Here's what I do, though.
Dynamic overclocking/underclocking
Turn off GPRS when not in use
Disable Push Mail
Turn off WIFI and Bluetooth
Turn the screen brightness down
Turn off the screen altogether, even when on a call, unless you need to see what's on it
There's a few tweaks out there that deal with enabling the power saving features on L2TP and stuff...

First post here-
I've had my wing about a week now and have a question concerning battery usage.
It has always been my understanding that batteries will develop a "memory" if you charge and recharge them under their full charge capacity.
i.e. if you use it down to 60% and then charge it to 100% it will remember that and not use the full original 100% charge. obviously over time not just from a single "half charge" like that.
So since every time you connect it to USB to sync it begins the charging process, won't that wear down the battery and make it develop such a memory?
Is their anyway to connect to to the PC without having it charge?
I have always preferred to have any mobile device drain it's battery to nearly empty before recharging to try and minimize the memory effect.
Thanks

Today's lithium ion batteries do not develop this like older rechargable batteries. You can plug your phone in at any time without worrying about losing battery capacity!

Thank chris30_2001, good to know.
oh and it's ALWAYS lupus

I listen to Streaming Radio with my Wing at work all day. I get approximately 4 hours of listening time before I have to swap out with another fully charged battery.
I use PBar to shut off the screen while listening.

I'm running the touch rom without the actual touch. I can't remember which one it is. I spend at least an hour a day gaming (text twist, random solitaires) on it. I usually hit up the web a few times a day for 10 minutes a shot. I use it as an ebook reader. I send txts constantly. I talk about half an hour a day. All this leaves me with about 30% - 50% of my battery by day's end. Now, if I turn on bluetooth all day it will end up around 18%. Wifi is such an evil power hog I never turn it on, EDGE is fast enough for me. I charge my every night under my pillow (it's my alarm too). Battery life has been the same since I got it about 6 months ago.
Edited to add: I also do some dynamic underclocking for things that don't need a huge amount of power, like my budget program, etc.

how battery drain in touch hd

I just order touch hd , and waiting for it. but I wonder how about battery drain on touch hd.
I got diamond one and it terrible on standard battery.

better than diamond thats for sure ما شاء الله

with extensive outdoor usage (gps running, wlan enabled but home wlan unreachable) my Blackstone is drained in less then 4 hours.

With my TyTN II (Kaiser) I have the same bad experience, drained in less then 1/2 day. Same with some other devices. But I think this is typical for this device class. With some directives the battery power can be saved:
- disable WLAN when going outwards
- reduce display brightness
- disable/shutdown GPS apps if not used
- buy a car kit ;-)
In my opinion WLAN and the display are the most power consuming parts.

thanks for the advice, normally i have recharge pda-phone every single day with normal usesage. hope to not worry about battery like a normal cellphone ;/

Don't have any problems with drain, even after steady use I still had 3 bars left :O

You are welcome. I am still playing with my new Blackstone, but I think with "normal" usage the operating distance will be 2..3 days.

Had a problem trying to charge it in my car for the first time. On a 3 hour journey with about 1/4 battery level left and running pocket player and TomTom when I got home still only 1/4 (or maybe even less) battery power left. I charge it through the USB port in the car stereo. Never had that problem with Polaris under same conditions. Seems ok at home running the same programmes and charging through the mains.
Any one else having trouble charging in a car?

I hope it stands more than one day only. Xperia has better values, my friend told me, it lasts two days more...

friend of mine just got a Xperia. will catechize him...

with heavy usage but turning off WiFi outdoors battery life has been pretty good lasts a day and a half.

In 3G mode, only with two full charges and a bit of heavy usage, cause I only have my HD from last friday, it's been lasting for about 1,5 day. I'm going to test it about one more week and then I'm going to test it in normal GSM mode.

With heavy usage lasting about a day.
2 hours movie
1 hr mp3
30 min calls
10+ text messages
1 hour internet through wifi
12 hrs standby
5 minutes google maps
Maybe 1 hr playing with my new toy (screen lit)
Probably about 2-3 days when my usage goes back to "normal".

I've charged my HD @ 15 o'clock and now is on 72% of battery

opps sorry wrong section, ment to be in the dream not blackstone how do you delete posts?

I have usually a heavy use on it (i.e. too much talking over BT headphone, regular wifi email exchange, rss update etc.).
I used to see it drain easily until I used the advance configuration to fix sd management, connection management etc. For some reason everything was off on mine.
Now with (fairly) regular use it can go one and half day almost.

True, no need for WLAN to be on when on the move. It's the most power consuming antenna in your phone. You can set it to disable if it can't find an access point for 1 minute. Bluetooth is also a killer... These phones are stuffed with radio's, don't turn them on all at once.

Oh, and my phone easily lasts a day, and I tinker with it all the friggin time, and use it quite a bit. But I only activate stuff when I need it, such as wifi, bluetooth, direct push. I rarely use GPS, yes of course this drains your battery in 4 hours, just like when you would place a call or watch a video or browse the web for 4 hours. Anything that uses a lot of radio activity or a lot of screen on-time will drain your battery fast.
I optimized power saving modes with schaps advanced config and turn the thing off at night.
Push email on winmo or apple phones is a joke. The way it requires to keep a GPRS connection alive is ridiculous. Blackberry understands this a lot better.
If you don't use it, you might as well turn GRPS auto attach off using schaps advanced config tool since that too will save a lot of battery time.

Recharged 20 hours ago. Normal use. GPRS Data Connection on, e-mail push each hour (i have flatrate) and i have 85% of battery left.

[Sol] Maybe: Sdcard Powermanagement disabled gives me more batterylife

I have noticed one thing yesterday.
From the moment i had my Rhodium (2weeks ago) i installed advanced Config 3.3 on my Rhodium.
From the start i had the "SDcard power management" enabled.
Since then i had a terrible battery life, 20% loss in 3 hours so at the end of the day my battery was empty.
And did not blame the powermanagement of this.
Trying to locate the power loss i used acbPowermeter.
After two weeks i came till the conclusion that there was nothing which drains my battery.
True out the day i use my phone for just a couple off calls and sms messages.
3G is disabled because the poor reception.
Also auto weahter updates every 2 hours and my mail is also checked every 1 hour.
Bluetooth is always discoverble which does not effect battery drain more then bleutooth off.
Activesync is killed and Opera does realy close and used the nopushInternet tweak.
So after testing al these and more.
Even how much those apps uses de proc.
I had to try one more thing, disable the SDcard power management in Advanced Config 3.3.
And today that config change made me verry happy.
Normaly i start working at 5am and work till 3pm in that time the battery has lost 60% power.
And today i was supprised my Pro II had 91% power left.
So i just want to let you know that in my case the SDcard Power management f*****k up my batterylife.
Specs
HTC Touch Pro II
ROM-Vers: 1.19.404.1 (51489) NLD
ROM-Date: 06/22/09

I believe these specs aren't that bad because before i disabled the power management my battery would be emty in 16 hours.
So i hope that my findings will help you all.

Bluetooth is always discoverble which does not effect battery drain more then bleutooth off.

Are you sure about that?
in most devices bt in descovery mode drains the hell out of the battery!
I always have my BT ON only, because thats all you need once you devices have been paired.

Hey Faria,
First off all i still love your rom on my old wiza200.
Back ontopic:
As i found on the internet and my findings with the discoverble mode that it is not on all the time.
It only opens the BT pairing when a device want to pair.
After that it closes and acts as BT on mode.
BT does not sends it signal all the time.
But correct my if i am wrong
edit
If i may believe AcbPowerMeter the power drain with BT on and BT discoverble is nill and BT off against BT on is that it isn't a power drainer

ha.. you mean you have it in a timed descovery mode. if that is the case then it is correct.
if i m not mistaking bt on only, drains less than 1% in 24 hours of the battery.

I get 7 hours of battery life and I'm a heavy user. I already have that option disabled. I need to improve this battery!!!

incredible!! your results are great!! any other detailed report, to clarify things a bit?? it would be interesting to have some data to elaborate some statistics and see what we come up with
in your fisrt post, you mean that you achieved the written results at the cost of only 10% battery life, or have I misunderstood it all??? if it's correct, wow!! °_° you have a nuclear battery! from 100% (and powermanagement enabled) I usually achieve 24 to 26 standby hours, 30min calls, 5 hours device usage (most of them connected on 3g). no bt nor auto connections of any kind.
thinking about it, it sounds a bit strange though: the OS is basically the same since quite a long time, and so the management of sd power (I think). so why would it do good (if enabled) on many devices, and not on TP2, having on the contrary such a bad impact on battery life?? I hope my question is clear enough!
since I'm no expert or programmer, I'd really like to have a little explanation by someone who really knows how these things work!
thanks a lot for the contribution, everything that may improve battery life even just a minute is super appreciated! best regards!

Nope my is discoverble the whole time.
About the 1% drain i am not sure, but after i am done with testing we will see how much it drains our battery.

I expect that my testing will be done with in two or three weeks.
Because i want to exclude every possible power drain and drain the battery till its empty to besure how long it takes.
Althought my battery isn't empty jet i will post some screens of the actual battery state.
And later this weekend when the battery is empty i will also post data of my findings.
With my tests i hope to save power and still be able to use the Pro II as its ment to be.
Or else it will be useless expansive plastic brick after 7hours of use time.
At this moment my battery has 43% power left.
And the last full charge was at 4am on 20-08-2009.
So its standby for a little over 54 hours. (current time 11:30am)
In my attached screen it say standby time 49 hours.
I do not know if this standby indication is the actual standby or what is left.
I mean that my Pro still has 49 hours to go.
Think there is a bug in de energy tab, but can not find anything on the NET.
This is what i have done the last 54 hours.
Why is tell you this? althought i am not an heavy user like many people here.
It maybe can help to compare my use with all you people.
- 4am 20-08-09: woke up and disconected my phone from the charger.
- 5am got to work, at work no provider connection so phone is searching for connection for little over 8 hours.
- 3pm got home, so now and then check the weather, play arround with new appz, had to put is some new appointments and contacts.
- Tryed some new reg tweaks, and took some pictures and make a short movie (1.39min) off the awefull weather over here.
- 10pm got to bed with 73% power left in my battery.
- Same story: 4am woke up and got to work to arrive at home at 3 pm.
- Did some checking on the weahter app, added a new contact, tryed some g-sensor games.
- And made two phone call about 10 minutes (not much for the last two days)
- Also send about 12 sms and 2 emails.
- Got to bed at 11pm and woke up at 10am with 43% power left in my battery.
- My mail is checked every two hours, no pushmail by the way
- I used the alarm function as my wake up call
I will let the battery drain completly and try some other possible power savers later this week.
And will post my findings over here including some findings i made with acbpowermeter and what effects background services or programms have on the battery.
At this moment i think i have charge my battery tomorrow morning if it does not shut it self off because of an empty battery over night.
If 4 days standby time is possible with little use then i'm not happy with the power drain.
Why: my wifes Omnia i900 is not used for over 3days (Backup phone at the moment) and has a been standby for 4,5 days and has 50% power left.
Okay i know i can not compare these two devices.
Because there different and we do not use the devices the same.
Later this weekend i will post what i have done and post some data and statistics.
And i will post which changes i made for my new tests week.
What i have done so far,
Energy settings:
-screenlight in battery power is full
-screen goes off after 1 minute
-device goes off after 2 minutes
Phone settings:
-band settings are set both to auto
Bluetooth:
-is set to discoverble
WiFi:
-Did not use it this test
Commanager
-Do not know whoe made it.
but is use the new commanger to quickly switch between 3G on or off.
Because in my area there is a poor reception of 3G
So currently 3G it is switched off
Advanced Config:
-sdcard powermanagment is disabled
-also the others mmc, nand, sim, async, pptp,l2pt
-Data connetions (gprs auto attach) disabled
-miscellaneous (auto daylight savings) disabled
Appz & tweaks
-manilla nopushinternet
-Opera wil close instead of minimize
-Activesync is killed by faking a server
-No2chem 1% battery bar
-Zuinigerijder TouchLockPro
-XDA-Developers GPRS 1 minute auto detechment
Rhodium settings tool:
-Auto rotation is off
-Power special tweak is switched off (next week testing it switched on)
So next week more data and background info

waiting to see the final results!!
btw, what is "power special trick"?? never heard of that.. sounds useful
the more minute of battery life we can obtain, the better!

how do you disable the sd card power management? i want to give this a try. also this is my first post and id like to say this site has alot of useful information!

any updates

I tried disabling and...well maybe there is some little improvement here, but I don't know if it's really because of this or if it's because of different patterns of usage during the days.. mine varies a lot.
as a raw comparison, it went from almost 60hrs standby and 5 of usage to almost 75 and 6 /6.5. both test with phone always on on 3g network, no data connections, no wifi, bt and such. just simple usage (documents reading, editing, tweaking, mostly PIM related tasks.
again, I'm not really sure it's power management related.. maybe V6Maniac did a more rigid comparison, mine's not worth it
waiting for updates
cheers

Palringo
Guys,
I am not a techie so dont flame me if what I say proves to be wrong.
When I installed cleanRAM and when went to the Customized Process List, I saw Palringo as one of the running processes. I remembered using Palringo on the day I installed it, but never after that, which is at least 10 days before. And it stayed there even after a day. Hence I decided to remove the installation and the process is gone now.
Now my batter is really good!!! I had a full charge by 6 pm yesterday and now it is holding at 84%. I did connect to Internet through WiFi for about 20 to 30 mins for skype call, updated weather and stock. Yet it is holding at 84%.
Let me observe it for few more days and let me come back to you if I find anything interesting.

it is known that certain programs are really nasty battery drainer. there's a recent thread somewhere reporting that a (maybe older( version of ESET mobile antivirus did the same. so we have another entry for the black list of abnormal battery drainer
thanks a lot!

Best way to increase battery life...

This isn't a thread for when your battery drain is excessive on standby, this is a thread dedicated to figuring out how to simply get more power to the phone for extended runtime.
I'm using a 5000 mah external battery pack for extra charge, and it seems to be good enough to last me at least an extra day or two of usage, which is great. It seems like the only other options are cutting up the battery door to fit an extended battery from the evo 3D or just carrying extra batteries...

Best easy change for me was always using wifi instead of the network when at home and work. Made a huge improvement

So....how to get the most time out of your battery in standby?
As you've allready said:
One of the biggest improvements is possible by using a Sensation or Evo3D battery. With that i get a nice 1% per hour in standby. (It's actually a bit lower than 1%).
While not using the phone it's unnessecary to have 3G activated. Recieving emails and texts via whatsapp, viber etc via 2G is good enough. For everything that is more datahungry you can allways activate 3G manually.
Keep background data turned off. I use K9 Mail which works independently and Whatsapp recieves messages too. But a lot of other stuff doesn't syncronize which means less wakelocks and thus less power consumption.
Same with locations. As long as you don't WANT to tell google your every step you can keep network based location turned off.
If you need a location fix quickly you can allways turn on gps for a moment. After using the FasterFix app (i guess you need root for that), i get a gps lock in 5 seconds, so i can determin my location really fast and share it with others (for intance via whatsapp) without having to keep it on all the time.
And last but not least:
You probably don't need to know the current outside temperature every 5 minutes. So set that to manual update too.
Doing these things doesn't turn my smartphone into an overweight dumbphone with a battery problem and i get a maximum of over 4 days of standby time out of it.
Normally my battery holds for roughly 35 hours (1 day and 11 hours), but it's usually awake for 1/4th of the time serving as my newspaper and video and mp3 player.
/edit:
Totally forgot:
Use llama!
You'll never have to worry about forgetting to set your phone on vibrate while at work and setting it to loud at home.
You can configure it so it only activates wifi at home and turns it off again if you didn't connect to any access point after a set amount of time. I haven't had to activate/deactivate wifi manually for ages without having to worry about it constantly searching for networks and sucking my battery dry!

Exactly what he said, but you can automate a lot of it by using an app called Tasker. I use it to sync all data on my phone for 3 minutes every 4 hours so it's always up to date. It can also automate the GPS on/off depending which app I use so it switches on when I open CoPilot and turns off again when I close it.
Tasker can also replace Llama if you can find 'profiles. to do it. Llama looks pretty good though.

I think the biggest drain is the display. With auto brightness on, the sensor will monitor the changes in your surrounding every second the moment you turn on the screen. Turn that off and manually control the brightness save a lot of battery.

Or just use lower autobrightness script.

I use Invisibright. Long hold on search softkey + slide enables me to set the brightness to whatever I want in a second no matter what apps are running.

It is still useless as your sensor is still working every time you turn on your screen. The sensor is draining your battery. Not the brightness value.

Autobrightness sensor drain
So you think that there is a greater drain from the light sensor than from an uncontrolled screen brightness?
Interesting thought. I'll manually set my brightness level a round20% for the next charge cycle and see what effect it has, though I suspect that as my display currently accounts for 20% of battery drain it won't make all that much difference.

I use juice defender and I think its actually working.
