*ORIGINAL TEXT EDITED AND UPDATED*
I have flashed at least half of the custom ROMs released for my G3 CID-unlocked MDA for the last 15 months. It has given me great respect for the efforts of kyphur, faria, molski, anchillus, and others. I have spent too much time, as well, following events here due to the 2 issues that leave my “Wizard” performing less than its best – the radio rom (stuck on 2.19.11 because of missed calls/messages) and battery life.
I do use a few add-on apps, but the main 3 I add to most ROMs that lack them are: batterystatus, todayagenda, and smartskey. I’ve tried placing the blame on battery life on overclocking (via batterystatus, I’ve run mine at all sorts of different speeds with and without cpuscaler, w/wo boost, w/wo extra indicators, etc.). I have updated, removed, reinstalled, backflashed (to ensure a extended rom was present, as many said this would fix the battery life issue) apps and ROMs and nothing has fixed the battery issue. Seemingly ever since WM6, I have been able to get about 24-36 hours out of my phone, about half of what I got before. Last night I went back to Molski’s Wm5 Aku 3.3 Crossbow ROM and over the course of several hours, battery life held firm. Then I added my push e-mail account and synced my mail for the first time (I have a lot of mail) which took like 10-15 minutes, and I dropped 10% of my charge (all levels reported per batterstatus, whatever the bias). Whoa, I thought. Well, I will chalk it up to a squirrelly initial indication of 100% because it sometimes seems to show that when it has just been unplugged from the charger, even if it soon resets to a more accurate value. Anyway, this morning the battery issue seemed to still be a problem. Could it be push e-mail, I thought?
So, I turned off the immediate send/receive, and my battery life improved a great deal. Wait, I thought, could it actually not be push e-mail (which would stink, because I NEED that), but the SD card access when it stores my attachments to SD causing the drain (this was suggested some time ago, but I couldn’t recreate at the time, because the CABs supplied didn’t resolve the issue)? I decided to check. I changed the push settings back to immediate (true push, not SMS triggered) and told the ROM to store attachments in main memory again. And guess what? My battery drain issue appears to be fixed!
I really hope this may be the case. It wouldn’t surprise me to learn that all the power users here are setting the option to store to SD card, or running apps off the SD card.
* MORE UPDATES*
I have been testing this theory for several days, and I can say with absolute certainty that the above fixed my battery issue. Some (WM6 and WM5) ROMs are better than others in this respect, but it is definitely fixed - life improved in all of them. I am currently using Business Edition v2 and it often shows 24mA consumption in BS. I am now seeing consumption under standby conditions of just a hair over 1% per hour, and excellent life even when I am working on it, using the phone, etc. And this is with bluetooth on, push e-mail, etc.
I admit I was surprised at the relatively limited response when I first posted, because this appears to be a gripe for a lot of people. Maybe I overestimated that....if it helps a post here would be nice, if only so others see it and can help themselves.
Thanks again to all the ROM cookers!
This could in fact improve the battery status for many people, and if so congrats on an awesome find.
However I do not have a data plan (being the poor college student that I am), therefore do not use push email. My battery life is similar to yours and I can stretch to maybe near 48hrs if there is very very little use of my wizard....
But I am glad we are on the right track

This might be it
I never thought of that. You just sparked something though. On both my HTC Wizard and my old MPx200, which has a full size SD card slot, I remember when I let the power completely drain out that one of the first things I couldn't access was the SD Card slot. I remember being surprised when I couldn't find it.
Nice Job! I'm willing to test with you but I will have to wait for two more weeks. I'm a freshman in high school and have final exams.
Good Looks
Good find, I went to do this and it turns out that I had it already set to that . Also, when not using your phone turn the screen off and while you are in call turn the screen off by pressing the power button up top. Also, changing the brightness of the screen has really helped my battery out and the fact that I had a bad extended rom. with all that said and your finding my battery has been great. and AHHH finals week here for me.. I feel for you guys.. Mine start tomorrow! BOOOO
You mean you ever made it more then 24 hours?
My Wizard needs charged every night. It's usually chirping by the time I get home from work
I do have push email set up though so I attributed that to Push.
Battery life is a bit of a bummer on these devices, but that's why I have a charger at home, in the car, and at my office, haha
Push definitely hurts battery life a bit, and that should be expected, but I have been using that for about a year and I really suspect that it is the combination of the original batteries getting "old" at 1 year and this SD card issue that is causing the accelerated decline. I am still optimistic, and my drain is still not too bad, so hopefully I can just learn to live with "fetching" my attachments to SD only when I need to see them (vs. having Messaging pull all of them automatically) to reclaim several hours to a day of battery life.
I can make it 24 hours. Usually at the end of the day say 10 or 11 my battery life is till about 50%. I tested it that night and didnt have to recharge till around 4pm the next day.
I'm sure that vettejock99 is on the right track for some users. My mail program (Xpress Mail) doesn't use the SD, so this wasn't an issue for me - only GPRS usage. When I use the card / applications that access the card, my consumption goes way up. I can see where an app that always runs in the bg and constantly reading/writing to the SD could have a huge effect on battery life, in addition to hardware that's left on - such as Wifi or beam.

I don't know what u guys are talking about here. I use the Faria Vanilla ROM and my battery lasts for 96 hours, it's amazing! But when used other roms I never had my battery last less than 48 hours.
One more suggestion about the battry life: always close all active programs. They really drain the battery. I tested it luanching 15 applications at a time, and guess what happened? The battery lost 50% in 15 minutes. So, that might be one of the other factors...
Oh, and here is one last thing. The battery drain is also high when the phone network is unavailable. If u leave your phone somewhere where there is no network signal it will automatically try to search the network every n minutes. So, that also causes huge power drain.
I wonder if this little SD card thing affecting the battery drain isn't noticed when surfing the net. I set the temp folder on the sd card for IE...just a thought

I dunno, maybe (as was speculated some time ago) the power management is turned on/off by one activity such as surfing w/cache to SD and handled differently when writing attachments......
By way of an update, I ALMOST added earlier today that my consumption was creeping back up again, though it still seemed to be about 20% lower (better) than before. I decided to uninstall TodayAgenda and BatteryStatus from the Molski ROM (the versions integrated into it), even though that would make it less desirable to use. The drain still seemed to be creeping up. I was troubled. Then I realized I had installed Today Commander earlier today to ensure I had an extended rom, which I did in fact have (check that box). Well, I installed it to the SD card - so I uninstalled it. And I removed my SD card. And once again, it appears that my consumption is back down. I have used 1% in the last hour, and that is something I have been unable to accomplish in some time. So.....I could be wrong, but I really think this SD card thing has something to do with it.
I remain hopeful this is it, and there is a way we can fix it, or that I can ultimately leave the SD card in at least, and install apps to memory (as there is plenty of room for my needs) and only pull attachments to SD as needed.
Anyone else looking into this?
last bump - updated OP
I thought I remembered seeing a registry hack, or something to that effect, which turned off the polling of the SD slot. I think it was supposed to dramatically improve battery drain times. I'll take a look around for the hack, maybe I'm just dreaming though.

You did, it's out there. Didn't help mine, though. I think that is because the polling does represent some drain, but it appears the actual writing/reading drain is the substantial part.
look here i think i solve this problem
http://forum.xda-developers.com/showthread.php?p=1259754#post1259754
increasing paging pool of the ROM causes the battery to roll down heavilly.. this was proven a long time ago in himalaya (xda II) section)..
but ofcourse this isnt only the problem..
-dOUbleOfour
i dnt know what my problem is. i charge my fone all night to 100% and take it out the charger only when am leaving for work. when i get on the train its a 40minute ride to work. i only listen to windows media player and by the time i get to work my battery is like 50% or less.
so i bought a new battery today. i will update tomorrow

That is a cause, but as I said, I had an extended rom, not corrupted, and still saw the drain, as have others. So folks need to ensure they have an uncorrupted extended rom, and they need to fix the SD issue in some way or they will likely have battery drain with many ROMs.
I recently upgraded to WM6 ROM, "Jwrightmcps Crossbow ROM Update 2.02.02 WWE", and all went well.
But then at 40% battery my phone died... and this is very similar to a problem I used to had in WM5.
Can anyone tell me which WM6 ROM doesnt cause the battery problem?
For the record, I don't think either my phone or PDA is damaged. The last time I had this problem, I went back to the service center (several times I might add), and they replaced everything eventually (both PDA and Battery). Since then it has worked fine (for about 6mths+), until I flashed to the WM6 ROM.
**** man, I hope this has not damaged my device. Out of warranty already.
I had a similar problem and also initially didn't beleive it could be the battery, but guess what -- getting a new battery solved almost all problems I had including the phone dying at 40% or above. So it might be worth a try...
IT"S YOUR BATTERY
Just trust me
the battery 'dies' after like 6 to 12 months. It just goes bad in a week.
Mine went out on like 20%, then a week later on 54%
replacing it fixes it.
mine crashes over 20%.... the battery it's new
I had same problem with battery,then I buy new battery from ebay, and then the battery status was OK it goes from 100- 4% with warning and everything. But the problem was that battery last only a couple of hours, even aftzer a few days nothing change I must have charger with me all the time.
Then I search the forum and found someons solution, that works for me too.
Just charge the battery full take the cable out and put it in again a couple of times so the battery is realy full charged, the put the device in bootloader mode by pressing Power + Light + Reset, which brings up an un-backlit screen with "Serial" at the top, and "v0.XX" at the bottom. And then just put your device somewhere and dont touch it until it died that coul be the all day. Anyway next day I put the charger in and again didnt touc for all day. And my problems are gone, the battery since then last fortwo or three days if I dont use it much.
Hope that will help somebody
Dears,
i used to read about this issue in the forum again and again.....so i desided to wrote this post....everyone was claming the battery is the reason....OK do not belive this.....it is the rom.....i used the wm6 for sometime and i was facing the same problem....and when my carrier started the 3G i had to switch back to wm5.....and now my device never turns off before i get notified that my battery level is too low it about 10% of the battery....so if you do not belive me just do this test....switch back to wm5...i am using now Hilme 3.5 v1.3.1
regards
Mine dies at 35% with wm6 and wm5 and my old battery, but never dies with my new battery.
Use Radio 1.15
My battery life increased by 200% just by upgrading to this radio ROM.
same here
i m also sufrer of same problem. now after this forum i m confused
Here is the simple fact of the matter:
Batteries are EXTREMELY complicated pieces of equipment
They often give false readings because the chemical reaction that creates the electricity is easily affected by heat\age\use\etc. Also, the electronics that measure the temperature are based on the false assumption that the battery drains in a predictable way down to the same level.
Your battery draining quicker\slower and dying when it says it has charge may be because of the ROM. However, this is HIGHLY unlikely. What is most likely the cause is external factors (eg heat, number of programs running, etc) or that the battery has "died" or become unreliable.
Recommendation: Try different batteries, and remember that batteries have a chemical reaction, before posting here
I don't know... I started having problems as well just after a ROM upgrade... but it was an official ROM upgrade. I start thinking this has something to do with the upgrade process, like some setting being "wiped out" during the upgrade and the battery going "out of sync" with the device, reporting the wrong battery level...
But, more likely, this is just a psycological effect, you install the new rom and then start playing a lot with the device to find the improvements, and you begin noticing the problem for the first time!
My relatively new I-mate JasJar also started dying when the battery level reached 40% the day i flashed WM6.
i posted here, trying to explain that it was perfectly alright 2 days back, prior to WM6.. pointless to say, everyone still said it was the battery 100%
well.. i got a new battery.. and it did indeed solve the problem.
but guess what.
i flashed WM5 back, and both batteries work fine there.
not sure what the heck is going on here.. but i'm certain there are two fixes:
- flash WM5 back on.
- get a new battery and stay with WM6

I used to think like you, but now I beg to differ, my dead battery never usable under any OS.
It used to be always dead at some % starting from as low as 0 (good ones) and increase until now it is permanent dead at 100%. I have all your intermediate voltages before reaching 100%.
If your's still usable than your battery is not complete dead yet or half dead or maybe soon to be dead.
By the way, I am using helmi_c aku3.5 v1.3 (add on version) as compared to v1.3.1 (vanilla version).
One last thing, please do use big bold characters in forum, sounds like shouting. Thanks!
You cannot judge the battery is old or new by just months.
This older version of Universal battery, it counts by number of time charged I think, inserting in USB for a sync and remove would probably counted as 1 charge.
I now do not sync using those working condition battery, I change to my dead battery for sync purpose.
As I sync only contacts, now Dotfred has a tool and now I hardly use sync anymore.
By the way, there is one guy in this same forum start another thread without reading this (closest info) or all other previous threads.
People like this deserved to be flamed, but I didnt.
IMHO WM6 uses and drains the battery different then WM5
My experience is that everyone that has problems with their device dying just switched to WM6. It has nothing to do with the WM6 itself, it's just that WM6 is more 'sensitive' to a low battery output then WM5. So if you switch back to WM5 it looks like it might 'solve' your problem but in the end the battery will die, it'll just take a little bit longer before WM5 appears to have problems.
You'll postpone the problem for a little while but it's not a fix
Just my 2 cents

Mine still working very good at WM5 as i told you.....just let the battery get off and recharge it till full....now mine is working great and keep working until 10% or less
The point is that WM6 treets the battery and power in different way then WM5. First when you upgrade to wm6 and start it first time it assumes that battery is full (the instruction says that you should charge your battery before uploding new ROM). If the battery was not fully charged then you have a problem. WM6 registers the point of current while starting first time and assumes that this level represents the fully charged batteryl. Then it is programmed for consumption of power according to processor cycles, so after such and such time of use of your device it should reach certain level of power. If your battery was not charged full at the start then it will always show false percantage.
The solution is to fully charge the battery (possibly using the way described in some post above) and then reload the ROM once more.
Of cource when you buy a new battery, WM6 registers this (each battery has unic number) and creats new pattern for this battery. That is way it is so importatnt to properly charge the new battery when you load it first time.
Hope this is helpful.

I have 3 original batteries.
In principle, good battery can goes to perfect 0%.
First battery started half dead (that is phone is dead 30%) after upgrade from WM5 AKU1 to WM5 AKU2 happen to be around 6 months after I start using the phone, I thought it was the problem with WM5 AKU2 ROM. My usage pattern of this battery is that I charge anytime I wish with Power charger and also during sync. This battery is still with me now after 1 year I have encounter the problem. The dead % grow (no change of ROM) until now it is around 100%, that is phone is dead just before it goes to 99%.
Second battery was bought the same time my first battery has problem, 1 year passed. Usage pattern are, never use this battery for sync or short connections to PC USB, never charge my battery until it is 0% (always possible) or less than 5%, never upgrade ROM using this battery. Always charge to LED turns GREEN & always sync & upgrade ROM with the dead stuck at 100% battery. 1 year has gone, the second is still able to reach 0% till now with battery last average 1 to 3 days, normally 2 days & sometimes 4 days depends on usage pattern.
Third battery, claim by vendor that some electronics is modified compared to the those bought last year. Charged this battery, use a few time to check if it is an ok battery, need to do this as I have ever bought brand new dead battery last year. After confirmed it is a good battery, I continue using the second battery and third battery always carry along as backup in case I used up the second battery.
Hope my usage pattern can help some of you to have optimal use of the battery and do not let the manufacturer earn extra money due to the problem in the old version of the battery. Anyway, this original battery will be discontinued soon due to end of life of this product. Guess I will have to look forward of getting imitations when my second & third battery is gone or maybe when my phone is gone too.

Hello friends ,
It have been 2 weeks since i got my universal (o2 xda exec) , I have tried most of the WM6 roms here , but most of them dont give good battery life..
Anybody know which is the best ROM with Best battery life? or any tips how to improve the battery life?
I usually read books and rarely hear music and i have 4 apps installed and i find the battery drain fast within 3.5hours. For this reason i turned off the phone and wifi. My uni is a new one , i dont want to have the charger all the time with myself.. I go places , do please help me..
Thanks in advance
battery life is awfull and unpredictable
I have the same problem. I use the same crossbow 2.12.08 version
with update radio ( from 1.15 ) to 1.18
I have a larger battery 3200 mAh, but th ebattery life is never more than one day. Though the battery is brandnew...
Worse is that when charging sometimes it shows 100% but most of the time this drops within a few minutes ( 2-4 ) to 97%
Then after 1-2 hours it is on 60% while usage is minimal. no WLAN, no BT
Also sometimes for some reason the battery is very warm ( during loading ).
When disconnected it turns out the universal is almost empty. Tried to disconnect the battery and leave it outside for 5 minutes then back in. but nithing seems to really improve. Also without memory card the results are more or less the same. Also always I close the applications fully.
Maybe someone can tell me what are the possible reasons...? Is is the software. Does it not see the actual charge correctly? Or is there a "hidden"battery user. Read the article about leds and all that, but this is way out of that league.
Rgds
I think that your battery is no good. My battery is 2 years old, it's the original battery 1650mAh and the battery life is 2.5 hours with WiFi enabled (internet navigation via WiFi)
If you want your battery to last longer, check the wiki:

Before blaming ROMs check the device with another battery. I had the same problem too, checked several ROMs and even downgraded to WM5 and at the end it appeared that my battery simply dies, while my other battery showed far better lifetime.
You are definitely having a battery issue rather than ROM. I am using 2.1.2.08 also and can get 3 days of normal mixed use from my original 1620mah battery.
Why not try "resetting" the battery, as discussed in previous forums, I for one can testify to it's success.
Is there a tweak out there that stops the stupid battery from guzzling? Im tired of charing it constantly and I swear it takes hours and hours to charge it back to full power. The thing cant last longer than a day without loosing power I cant stand it. Whats making it use all that power? I thought maybe if I switch wireless it would help but I didnt notice a difference.
I can get 2 days out of my battery.
I let it drain to 1% and then stick it on charge over night. When i get up the battery will be at 100% and then 30 minutes later down to 90% but it settles down after that.
I do not have wifi and bluetooth on all the time, just when I need to.

I don't understand people telling battery lost for 2 days..... even if we keep phone idle it will lose power in 24 hrs i believe....try like this try to use ROM with out manila & with manila once you will know the difference other than that there is some tips to save battery in Energy ROM thread in 3 rd 0r 4th post ..
4 days normal usage.
Manila2, GSM
15 minutes call, 6~10 text message, sync exchange, 30 minute ebook reading per day
If I build rom myself from the kitchen. It usually runs for 2-3 days.
However, in most cases when I try decent cooked ROM, for example, Energy - battery drains in about 5 hours. That's been the case with other cooked roms as well.
I suspect that some popular configuration change done by cooks causes battery to drain in certain environments. Would be nice to find out which change is that.
Processes and services often place a strain on the life of the battery; add to the mix a buggy service or application that further shortens battery life and one has an unusable device.
Another habit that can shorten Li-ON battery life is full discharges - near 0%. One of the members put out a thread a while back on research he/she had done on batteries - worth the read if you haven't already.
Cheers,

I just had the same experience, cooked for the first time and my battery was better than it has ever been!
Since then I have flashed to RRE 21731 6.3 and it seems my battery has stayed the same (Brilliant, 2 Days no problem).
The only thing ive done differently is I have used the new UK Voda rom as my Stock Rom that i flash before flashing custom, and i believe this may have something to do with it...What, I don't Know.
I also believe changing the Radio After a flash can affect battery life, I always try to flash a new radio before a Custom rom.
I have wondered for some time wether the European Touch Pro is slightly different to the US Fuze in its hardware, Since most Cooked Roms are configured for the Fuze maybe that is what it is?
maybe we will find out..One Day
turn off 3G and you will get much better battery.

That will ****-up your battery, you should never let it drain to 1%, just charge it when you have the time, preferably before it drains to about 20%.
I guess it all depends on the eye of the beholder, I come from the Diamond part of XDA, and we are lucky to get 24 hours on the Diam.
I was happpyyyyy with my new TP battery life -compared to Diam that is-
But ya, turning of 3g and being picky about processes and back light helps.
Greets to all.
Search the development and Hacking thread for Windows Long Life/save your gonads. Chainfire is developing a neat application to automatically switch from 3G when not needed. I tried an early version and it seemed to significantly increase my battery life.

An app that may help is Advanced Task manager, it has a widget to end all running processes/tasks which i tap before putting mine to sleep about 1000+ times a day it seems. go in and exclude ones you may want to exclude always and then its as simple as 1 click. as everyone else said, no gps,wifi,3g when not 100% necessary. also, get widget "toggle disply" from rounded labs and keep your screen completely dim (not like you can't see it...), being able to make it bright when you step outdoors. Also, toggle backlight app for root users keeps the pesky keyboard backlight off when you don't want it on (suggest making keyboard shortcut for quick toggle). last but not least because i'm sure theres plenty more, but yesterday i switched to cyanogen's newest stable ROM and it seems to be much more effective than any other i have tried in the means of saving battery life. had wifi on after a 98% charge for about an hour and a half (30mn usage) and it only went down to 91%... wow.

Firstly I don't think this is the right sub-forum for this question since it's not a specific ROM question.
Secondly, try nueDynamicClock, if you use the right settings, you'll extend your batt life by at least 1/2 a day if not more.

If I build rom myself from the kitchen. It usually runs for 2-3 days.
However, in most cases when I try decent cooked ROM, for example, Energy - battery drains in about 5 hours. That's been the case with other cooked roms as well.
I suspect that some popular configuration change done by cooks causes battery to drain in certain environments. Would be nice to find out which change is that.

It's really very simple. Flash an awesome rom, and the battery burns and burns. Flash a rom you hate, and the battery lasts forever. Don't over-think it.
hi guys.
i was eager to start up this discussion and am glad to find it here itself.
even am really finiky about battery.
tried alot of thing but cudnt find any spcl tweaks.
though i came across some registries from advanced config and other wise also but they seem to be more worse.
;IMPROVE BATTERY PERFORMANCE
[HKEY_LOCAL_MACHINE\Comm\AsyncMac1\Parms]
“DisablePowerManagement”=dword:0
[HKEY_LOCAL_MACHINE\Comm\Irsir1\Parms]
“DisablePowerManagement”=dword:0
[HKEY_LOCAL_MACHINE\Comm\PPTP1\Parms]
“DisablePowerManagement”=dword:0
[HKEY_LOCAL_MACHINE\Comm\L2TP1\Parms]
“DisablePowerManagement”=dword:0
when i use these tweaks the power consumption of my rom reached to 4.112 volts(as per power detect) which otherwise without these tweaks is 3.992 at startup.
more power consumption i guess means less battery i guess.
and even if its not still these tweaks as per my usage show bad results.
why so?
and arnt there spcl application which can detect the packages which might consume more battery, as i have over 50 packages in my rom and it'll hell to check which eats more.
Some tweaks I do
I have also found for me that disabling these things in advanced config also helps.
Performances
> File System cache: Disabled
> File System filter cache: Disabled
> Glyph Cache: 32kb (advised) I'm not sure if disabling this one is a good idea. I like having a little bit of glyph cache on my device.
Light senor
> Light sensor polling: Disabled.
*Note: If you want to still have light sensor on (this means the auto backlight feature) I would set the:
> Light sensor polling interval: 2000. This will make it poll every 2 seconds instead of every .2 seconds. I would even try setting it to 5000.
The backlight will make a huge difference on how long you battery will last. The brighter it is the more the battery needs to light up that screen. If you turn off the polling all together it will make the battery last longer.
Also running fancy UI apps will also deplete the battery more. Just common sense really as another poster alluded to earlier. The more things you have running and sucking up memory the more battery it will consume. If you disable TF3D or other apps such as this you will get your battery to last longer. Given that these devices are meant to have these types of programs on them you will have to weigh the options of how much you really want to "tone down" your devices to get the most out of your battery.
Also different radios will cause you battery to last longer. I suggest to everybody that they try different radios to see which ones last longer. Also people who live on the edge of 3G and EDGE area will cause the battery to drain faster as it constantly switches in and out of 3G coverage.
WMLongLife is a great app if you don't need 3G while you phone is just sitting in you pocket. It works great for me and when I want to use 3G I simply launch opera and the program will automatically enable 3G once again.
There are many things that you can do to improve your battery life. I encourage everybody to find what is best for them given what they use there device for and try and test things out. The best way to tell which works best for you is to simply try it out for yourself.
**NOTE** I also set all ROMs that I flash with a page pool of 0. I don't know if this has any real effect on battery life but it does seem to make my battery last a little bit longer. Not sure if this is a placebo affect though.
So i have decided to say something, and to write a little "MY GUIDE" :
First of all, this thread is due my AWESOME BATTERY LIFE
I'm running Insert Coin 3.4.1 with Bricked 1.4r1 Kernel.
I have done following steps :
0) First of all, you have to drain your phone dry (dead, till it powers down itself).Turn of fast boot (this is very important)
1) Turn your device ON and Charge the device for 8 hours or more
2) Unplug the device and Turn the phone OFF and charge for 1 hour
4) I wiped battery stats then when finishing those 1-3 steps.
5) Used phone regular.
6) For next 2 charging cycles you have to again discharge your phone untill it powers down itself
7) Charge it for 8 hours (i did it overnight)
Click to expand...
Click to collapse
After that 2 more full charging cycles you can charge your phone as much as you want and whenever you want. Charge it on every percent..
When you are charging your phone (after all 3 cycles), try to charge it when it drops under 30% and to charge it untill fully charged green light.
But i understand that sometimes you cant manage to charge it fully and when it is under 30%. Never mind. It is recommended but it is not required every time.
I'm trying to completely discharge and charge over 8 hours once per 1 or 2 weeks.
And after all this i have very good battery life.
With moderate use, my battery lasts over 24 hours (moderate use - lotof voice calls, lot of text messaging (SMS), checking on foursquare and little surfing over mobile network (HDSPA), alot of surfing over home WiFi.
In standby it cant be compared to anything i have heard here : I have 1% per 3 hours drain in stanby.. maybe even more hours, i cant properly determine but overnight when it is not charging i loose not more than 4-5 %).
My setup on phone is following :
1. Manual setup of brightness (im thinking of getting baadnewz auto brightness tweak)
2. All options in sound settings ( increase in pocket mode, flip over for speakerphone, quiet ring on pickup etc) are disabled.
3. Network is on GSM only. When i need HDSPA i change it manualy.
4. Auto sync is off.
5. Vibrate feedback and typing vibration is ON (i cant live without it ).
6. Dont have any battery saving applcation (juice defender, watchdog )
7. I dont have any mA monitor . Im fine without looking at wrong values monitored . I just have BattStatts (percentage shower).

I hope you like this, and i hope this will help to some one here.
After all this time on this forum (over year and a half), a lot of people here helped me a lot with my problems with my previous device (HD2) and with my current device (Sensation), so i was in need to try to help other people with major problem (battery).
If you want, put this thread sticky, move it wherever you like, if it is helpfull.
Best regards folks.

p.s. If this helped in any way, or you find this post(guide) useful, don't be lazy to click thanks button I thank to you all for your support
Thanks for the info!
I just flashed Faux 0.2.4b kernel on my ARHD 4.1.5, gonna try this whenever I have enough time
Would appreciate thanks button hit
And , yes, try it.. and report results pelease
For example.. I charged my phone today, took it of charger 10am..
With moderate use i have 98 percents now.. It is awsome
That's called bump charging. It may increase short term battery life, but depletes long term battery life. HTC recommended you do this ONCE every couple of months.
Plus our batteries are lithium ion, so doing full charge/discharge cycles will practically have no effect. You could do it just to calibrate it wight the phone, so as the phone "knows" what's 100% & 0%. But other than that, fully discharging these batteries could harm them. These batteries like partial discharge. So charging them when they get to around say, 30% is more convenient for them.
Just thought I'd let you know
Sent from my HTC Sensation Z710e
I didnt said to repeat this every day or week..
I said you should have 2 full charge discharge only once after u done 1st couple of steps..
Full charge and discharge once per 2 weeks will, in no way, harm our phones..
And i said
When you are charging your phone (after all 3 cycles), try to charge it when it drops under 30% and to charge it untill fully charged green light.

I have done steps from above, and i have great battery life.. short and long..
I know our batteries are lithium ion, and i know a bit about them (im finishing Electrical engeneering College here in Serbia (most difficult ever ))..
So
To recap..
This method CANT harm your battery or device.. It can only help your battery life.. Try it.. See it yourself
Thank you for your guide.

Woah, take it easy my Serbian friend. All that I'm doing, is stating the facts & trying to help you understand that what you hear about charge/discharge cycles are just carryovers from previous batteries where it was good to be do several full drain/recharge cycles.
Here's a perfectly clear explanation of the differences coming from experts: http://androidforums.com/incredible-tips-tricks/69534-battery-charging-myths.html
And a more detailed one:

What you experienced is bump charging, like I said, it may increase short term battery life, but WILL decrease its long term usability. So come on, this is a community, we learn from one another
@mzmo :
Mate.. You got me wrong. I appreciate your post in this thread . I find it useful. Ofcourse we learn from each other.
The facts ive put in OP thread are facts from my phone directly . First steps of guide was in mail HTC has responded to me.
So, all in all, thanks for your posts ,and for your future posts.. I find them all like big contribute to XDA community.. After all, i made this thread due to that
Cheers mate
Which bricked kernel version is better for insertcoin 3.4.3, v1.4 or v1.5
Thx
Thanks for the info.. very helpful...... i will try it out frm today. i have a huge battery drain
using ARHD 4.1.7 with faux latest kernel
