BATTERY DRAIN ON WM6 vs. WM5

Hi - experiencing battery drain on wm6. Anyone experiencing similar problems?

Change radio version
I must change radio version, i tried 1.38 same problem, now i'm using 1.40.30.00, problem solved.

First it depends on the Rom you are using and on the software running in the background.
And of course it depends on the radio. I'm running Black3 with Radio 1.41.00.10 and think the battery is lasting longer then before.
Short example:
Thursday morning at about eight I turned my Tytn on after charging the whole night. Then I used it during the day for a lot of phonecalls, downloading some emails and playing solitair. At about 09.00pm I switched to flight mode until friday 08.00am. Again I used it during the day for some phone calls, friday evening the battery was at 20% and I had to charge it. I think this is a respectable battery life.

i am getting very similar battery life. at the present time (8pm sunday) i am on 30% i have not charged it since saturday morning.
i was on the phone for about an hour today and about an hour and a half on the saturday, as well as lots of messages, bluetooth/gps occassionally and never switched it to flight mode.
i am using radio 1.41.00.10 and LVSW 3.30.00.9 05/07

Battery Tips
My battery life is pretty similar. Its more down to what you use on your phone and how your radio rom acts than differences between WM5 and WM6.
Things you can do to improve it are:
1) Turn off receive all incoming beams under settings>connections>beam.
2) Set your band to GSM by pressing the 3g/H/U/Whatever icon at the top of the screen then choosing settings>band and change select your network type from auto to GSM. If you receive an error saying the data call already exists, you may need to turn on flight mode first. I find gprs fine for mail and web browsing and mms stuff, I only really need 3G for video calls. Search for Daniel Herrero's Bandswitch if you have difficulties.
3) Turn down your screen brightness, if you need a light that badly, buy a torch.
4) For those that use an underground mass transit system, switch to flight mode when you are underground, otherwise your phone will continue polling for a signal.
I can usually get 3-4 days battery life with my phone with direct push on between 7am and 7pm moderate phone use and a bit of browsing.

Radio Upgrade
Thanks 4 da replies guys. I'm currently using radio 1.38 - Where can I download the radio that would give me better general performance & battery - which would be better 1.40 or 1.41 - where can I download it from?

Radio Download
Oops.....& my ROM is Pro Black 3.0.1 (on HTC TyTN)- which radio would be great?

I'm satisfied with 1.41, but its the best if you try both for some days to see which one is working in your area best.
Here you can find the radios:

Help on Installation
Thank u so much. As I am a new user please can u help me. do I just run the exe file on my laptop - will it affect rom? will anything on my rom change? can I reflash to a previous version? I heard a member say in a thread that flashing the radio could be dangerous and one could break the phone - please advise me on this. Many thanks

hi, just my two pennorth. Having tried 1.41 with Black v3, I found my battery draining very quick, went back to 1.38 which I have found gives better life. Although I do use it mainly for calls, not data. This is on UK Orange.

DATA Switcher on today screen
Hi guys, Daniel Herrero has done an amazing job! Thank you Daniel! You can now have an icon on your today screen that switches between GSM, GPRS, 3G in 1/2 simple clicks!
go to http://commmgrpro.com/_wsn/page3.html

Hmmm, Daniel Herrero's Bandswitch, now where have I heard that name before......?

Chrisjasper
THANKS CHRISJASPER for telling me about Daniel's Bandswitch. Works like a bomb!

De Nada, its nice to see some enthusiasm.

I have to say that I read some advice on another thread regarding battery drain and someone suggested unchecking the box for incoming beams in the connections for the IR. I think it cut the drain by 25% for me.

hy all. ive tried the following:
black 3.01, radio 1.38 ==> fast battery drain << 1 day
lastest lvsw, radio 1.38 ==> fast battery drain << 1 day
htc latest wm5 wwe rom, radio 1.38 ==> long battery life >> 1 day
black 3.01, radio 1.40 ==> fast battery drain << 1 day
lastest lvsw, radio 1.40 ==> fast battery drain << 1 day
htc latest wm5 wwe rom, radio 1.40 ==> long battery life >> 1 day
black 3.01, radio 1.41 ==> fast battery drain << 1 day
lastest lvsw, radio 1.41 ==> fast battery drain << 1 day
htc latest wm5 wwe rom, radio 1.41 ==> long battery life >> 1 day
so you can see, its not the radio (at all)!!! and there is a real big difference between wm5 and wm6. after a few hours you can see, that wm6 drains the battery very fast.

Battery life ok, but dropped calls
When I switched to 1.41.00.10, I had good battery life, but I couldn't answer calls before they would dump.
I rolled back to 1.40.30.00, and that seemed to solve the call dropping issue. Battery life is still good also.
YMMV, depending on what signal strength you have, +1 for turning off incoming beams.

Thanks for this information. That's pretty conclusive and reflects my own experience (that WM6 drains the battery much more quickly than WM5).
But it shouldn't put people off upgrading. WM6 is so much nicer (and faster) than WM5 that it's worth the shorter battery life. And most people will easily get one days use out of WM6 (unless you're online all of the time).
I recommend two things to improve battery life - switch off the phone and remove and replace the battery before doing a full overnight recharge (do this once to recalibrate the battery). And download the bandswitch utility to force GPRS for routine data connections (although WM6's seamless transfer from HSDPA to 3G to GPRS is wonderful and you will lose this).
I switched on my phone at 9am this morning (I switch it off every night - good for the device, good for the battery, good for my health and who the [email protected] wants a phone call at 3am?) and I've made a couple of calls and a few texts this morning - and it's still at 100%.

I am not sure whether part of the battery drain problem might be with the latest WM6.0 kernel that the ROM cookers are using? I was using an older LSVW version (I think his second version) for several weeks and was noticing far superior battery life than I had on the stock Cingular WM5.0 ROM that was on the device when I bought it. When I upgraded to the latest version, I noticed that battery life was quite a bit worse (same apps). I tried both the 1.38 and 1.41 radio ROMs and it doesn't seem to make any difference.

I've been experiencing poorer than usual battery perforamance since upgrading to Custel's WM6 ROM. I verified the settings that Chrisjasper suggested but Custel's ROM comes pretty much configured that way from teh start, I made a minor adjustment to my screen brightness but that was all that I could do.
I would typically be able to get several days out of heavy phone usage and moderate data usage on WM5 with plenty of apps loaded. With Custel's ROM I've not loaded any additional apps as of yet and still have crummy battery performance. I've been hitting the 10% warning marker almost daily for the last week.
I'm looking into other fixes for it on the forum as well, I'm not going to jump ship back to WM5 I love WM6.

lose 70% charge in 1 day!

hi
i have no prolem with my p3300 until 4 days ago!!! suddenly my device use 70% of battry in 1 day! i try soft reset, but not solved! also cpu goes to 36santi grad! but no process in task manager.also i try airscanner antivirus! and no virus ...
i use artemis tuch 3
please help me

Hi,
I am having similar problems since I installed Black and Blue 4.3.
Phone appears to discharge twice as fast. However, sometimes a soft reset seems to increase the battery again!!
I am going to try a hard reset to see if that fixes it. I have also ordered a new battery.
Anybody else had this and more importantly did you find a solution.
Regards

same here on orbit.all started 1 week ago.the phone is 8 months old.I can't believe the battery is gone so fast.

same here
same here battery life is crap
even with obly a few calls
whats up? is it the rom?

Okay,
A number of us with the same problem.
Can you all confirm what model you have and what ROM you are running. Also any new apps you have installed at the start of the battery drain. I will kick off
T-Mobile MDA Compact UK model.
Tom Condon's Black and Blue 4.3 ROM.
Only new software is AC S2U2 latest version.
Regards

htc p3300
artemis touch 3.0
no new software
bluetooth and wi-fi is off
no program running in task manager
but when i put my device near headset,i can hear some sound like TEGH TEGH!!!! every 1~3 sec.
i know it will solve by install new rom,but i want to find main problem. today i turn on then turn off my all units(bluetooth,wi-fi,camera ...) i must stay and see what will happend

Yeah thats the reason why i sell my Artemis, battery life is just crap. I call allot for work and use my phone allot, my battery is good for just one day . So byebye artemis and welcome HTC Touch .

I had these problems to..
Who I fixed it: I flashed original t-mobile ROM. Finished the install EXT-rom..
Did a hard reset, 2 soft buttons + reset, then green ring button..
Installed the USPL then HTC WM6 ROM, before ext-rom installation a reset. Then did a radio rom update, to latest version.
I can go up to 3 days without needing to recharge with GPRS @ 30 minutes sync..

Hello,same horrible problem.After 4-5 days the upgrade to B&B 4.1 with flo3the power of battery go down very very fast and a working day is impossible.When i bought the Artemis the first thing thats wondering me was the working life, but now...
I kill all task in background,set to maximum power saving, without effect.
Don't want to think that the best solution is to come back at wm6 standard.
P3300
WM6 5.2.1620
B&B 4.1
Flo3
SDHC support with 4GB card
DualSim 15th generation

I recently read a thread - either here or at ppc-welt.de - where some people found out that the gsm unit consumes a lot more power when you have a cooked ROM. When they put their Artemis next to some speakers the got that strange buzzing noise that you usually get when someone calls or you receive a message.
That sound in the speakers was there a lot more often than usually, when they switched back to the official ROMs the problem disappered. If I can find it again I will post a link. I haven't had any problems with my battery yet using Touch 2.1 WWE, only after a fresh upgrade pdas seem to consume a lot more power for a few days and get back to normal then.

what a pity because installing betterystatus (or configuring it properly if you had it already) would probably solve all that problems.
most (if not ALL) roms come with batterystatus... and sometimes it seems to misconfigure itself and overclock your CPU very much, which ofc leads to fast battery discharge. configure batterystatus to 201mhz and problem solved (or even lower if you dont need uber speed mobile, but loads of battery)
my p3300 battery lasts 2-3 days, doing some calls, using bluetooth for sync, listening to some mp3 while in the underground and using tomtom to find a street 15 minutes. nearly 4 days if totally on standby

Hi,
I have reinstalled my phone using the T-Mobile ROM.
I will let you know if that sorts the battery problems.
Regards

I had this problem after installing the htc official rom. I installed back the touch rom from the forum and everything is ok now. Tha battery last me again 4 days with mixed regular use.

Hi,
Tried the T-Mobile ROM and whilst under general use the battery drain is slightly reduced as soon as I ran Tom Tom it dropped by about 30% in 20 minutes. When I first got the device I could run Tom Tom for about 4hours before the battery died.
I have ordered a new battery so will see how that goes.
It is a bit frustrating not being able to pinpoint the problem.
Regards

my mobile service provider found problem with their GPRS!!!!!!!!!!!!!!!
i just install this software and disable GPRS
just 23% battery used in 20hour!
but i dont have any program that automaticly connect to internet! and also always i keep my quickGPS up to date by active sync ....
please test this and DISABLE your GPRS and see what happend!! is it our problem or another ... ?

Hi,
Disabling your GPRS may fix the problem but it should not affect the battery this way.
I have just put in a new battery and it is charging just now.
Will update how the battery drain is with the new battery.
Regards

Hi,
Did a quick test running Tom Tom and battery usage is back to normal with the new battery fitted. Obviously the old battery was on the way out.

Battery life and radio and rom version

hey guys plz post ur battery status here along with the radio version you hav on ur phone
this wud be of great help for future reference for all of us and to select the best Radio version
Plz charge the battery to full and use it upto the limit
lets see which Radio and Rom drains the minimum battery juice!!
Smartphone battery life is obviously the prime factor in buying a Smartphone
Thank you guys
plz join in and help all

plz update guys
it wud really go a long way in helping all
atleast post ur recent usage stats

standby 22hours
talktime 1hour
internet 30mins
now battery is at 23pc
my rom is the official htc 6.5

That will depend on the usage and can be different as some radios work better with some mobile providers
The best way is to test several combinations ROM/radio till you get the best.
I´m using latest Energy Photon 6.5.1 with radio 4.46 and my battery lasts me 36hr aprox. with a lot of usage, customization, calls, wifi, bt.

ok, how in the world are u getting such good battery life...ive got the same rom loaded and ive sent about 20 text messages and its already down to 75%....also, it appears as tho my data connection keeps turning back on by itself and i KNOW for a fact that there is nothing auto updating that would cause it to turn back on

my data connection keeps turning on and off as well. it's annoying. i've turned everything off but it still keeps coming on 3 min after i turn it off

I'd be interested in doing some kind of standardized comparison also. I read posts where some people get great battery life, some people get terrible battery life (I'm in this category), how some people's battery life improve after a few recharge cycles, etc. At this point it's hard to tell whether some people have faulty batteries, some people use their phone more than others, or some ROMs just consume more battery than others. To do a comparison, we'd had to have some kind of agreed upon methodology and here's my proposal:
1) Install acbpowermeter. Just assume that it works the way it's supposed to. Even if it doesn't, since everyone uses it, the methodology is the same so that results can be compared.
2) Whatever ROM/Radio you have, just report it.
3) With phone plugged in, soft rest your phone and wait 5 minutes for everything to get loaded.
4) Turn off the backlight, and run acbpowermeter. It will start measuring power consumption.
5) Turn off the phone right away and after 5 minutes, turn on the phone and pause acbpowermeter.
6) Report your average power consumption and total power consumption, as given by acbpowermeter.
This will give us an indication of how a ROM/radio performs with no activity. This assumes you have no other programs installed/active that contributes to power consumption, but even if you do, I don't think the results would be that far off. I'm curious to see what the idle power consumption is. You might want to run this a few times to get some consistent results before reporting. Also report if you get some spikes in the graph or if power consumption is stable during the 5 minutes. My initial results are an average of about 90mA and 6mAh during 5 minutes. One big spike up to about 360mA at the beginning. This would mean about 72mA per hour or about 21 hours for a 1500mA battery. This is close to my experience of going from 100% to 80% when I wake up in the morning (5 hours of sleep). Terrible. I might just have a bad battery....
EneryROM 11/8 23504. 4.47 Radio.
If anyone else has some suggestions on how we can compare battery consumption, do share, as I think this would be useful information to have.

it has good stability nd battery life!!
but still i like the leo or manila 2.5 very much!!!
hope it supports landscape soon!!!!!!!!

[Q] [solved] Suddenly, horrible battery life out of nowhere

Hey guys,
I have been trying to solve this on my own for two days now, but I would like to consult the forum now.
So, I was running Pink Sense 1.8 for about 2 weeks with setCPU profiles and was getting satisfactory battery life. I had re-calibrated the battery info maybe 2 weeks before flashing the Pinky ROM (as described here: http://forum.xda-developers.com/showthread.php?t=755903).
All of a sudden, without any app installation or change to either the ROM or software/hardware settings I started getting horrible battery life. The battery would drain completely for less than 6 hours with GPS, 3G, and WiFi off.
*Another strange thing (which I don't know if it was related to my battery issue or not) was that when I would plug the charger it would turn the screen on but switch to the default clock app instead of the HTC sense homescreen. If I pressed home or back it would disappear. This would happen randomly and not always.
So, I figured it's time to jump ROMs and I decided on LeeDroid. I wiped cache, etc. and flashed the ROM. Out of the box the battery life was again pretty crappy (the battery was virtually disappearing in front of my eyes). I found some threads where it was suggested to disable market notifications and that slowed the battery drain a bit but it's still crappy.
I just charged it fully, 3G and WiFi off, and was with the screen off for 99% of the time and it still drained 18% battery in 1hour and 25 mins.
So, my question is - what the hell is going on???
Should I wipe battery info? Should I install a non-WiFi n rom? What more can I do?
I would really appreciate help and advice.
p.s. I am running the latest radio too.

wich radio have you the .23 drains the batery with my desire try with the .30_2
the battery life is better.
did you try reboot your phone maybe your optical joystick dead and drain your battery.

load any new apps recently?

As I said, the problem appeared with absolutely no new apps installed and persists after flashing a new ROM.
How do I know if my optical joystick is dead? It still works if that's what you mean (although I don't like using it).
I will try flashing the 30_2 radio, thanks for that suggestion.

If it works he's not dead
after flashing your radio and if the battery still drain check if the rom you use has his own rules for the cpu freq. if you are in that case don't use cpufreq or something like that because of conflicts.
PS: Sory for my bad english

Thanks, I just flashed the 17_2 radio. It doesn't look like LeeDroid has any requirements for cpu frequencies. I will post an update after an hour.

There seems to be no change with 17_2 radio. 15% drop for 1h45m. I will go through a charge/recharge cycle and if nothing has changed I will flash the 30_2 radio.

Some people had the same effect. It happens when you flash your ROM while the phone is connected to power/charging. The battery stats simply get messed up.
An easy indication for this is if you charge the phone fully while powered on, LED is green, as soon as you unplug the charger the battery drops to some 90%.
The fix is easy too. If the phone is fully "charged" while on, disconnect the charger and switch it off. Then plug the charger in again. The LED should turn orange again and the remaining percentage will be charged. Wait until you have a green LED and your problems are hopefully gone.
Look out for the battery calibrating thread here for more info.
Hope that helps...

Thanks for the suggestions. I always thought it would be better to flash with the ac adapter plugged.
I have tried the method you described above but it hasn't really solved any of the problems.
The battery drain is now at least manageable - i had 50% drop while sleeping for 6 hours (at least it didn't drain it completely). I am going to flash the 30_2 radio and try again.

If you have access to a spare battery, maybe you can try that too?
Normally when I have unexplained problems with the phone, the last drastic step I would take is to wipe everything, data/app/cache. Do a nandroid backup first so that if that doesn't solve your problem you could always get back all your setups.
You could also try Titanium to help save your setup. But I would be careful with what I restore. The last thing I would want is to get the messed up setting back in.
I have noticed also whenever I flash a new rom, the battery seems to get worse. So I would always do a recalibration. The proper step is here:
http://forum.xda-developers.com/showthread.php?t=755903 (and wipe the battery status on the last power up before using).
Lastly, I would use as stock as possible first to see if it is things that I introduce that cause the problem.

I think I can definitely confirm the radio is the problem. There is barely any battery drain in airplane mode (1% drain per hour with WiFi on). I am back to 32.43.00.32U_5.09.00.20 but it seems to drain battery faster than before.
Now that I think back, this battery problem started when i switched to the newer 32.47.00.32U_5.10.05.23 radio. No matter what I do now though even after rolling back to older radios it's still a problem. Damn it.

Ok, I have awesome news! Thanks to user "lenik" on modaco forums I got some extra RIL settings (radio settings) he found for Softbank (my cellphone company here in Japan). Here are the settings:
ro.ril.enable.a52=0
ro.ril.enable.a53=1
ro.ril.fast.dormancy.timeout=3
ro.ril.enable.sbm.feature=1
He said the first two should be found on most ROMs, while the last two are probably carrier specific for SoftBank. Anyways, I just downloaded the latest LeeDroid ROM, modified /system/build.prop file (none of the above settings were in there) to include the above settings and ... got a 5% drop in battery for 10 hours on standby (wifi off, setCPU set to 245Mhz when screen is off). This is unbelievable.
Anyways, here are lenik's blog posts about it:
http://lazydroid.com/2010/06/battery-life-improved/
http://lazydroid.com/2010/06/back-to-1-21-...ry-consumption/
I hope this helps other people out there!

Anyways, I just downloaded the latest LeeDroid ROM, modified /system/build.prop file (none of the above settings were in there) to include the above settings and ... got a 5% drop in battery for 10 hours on standby (wifi off, setCPU set to 245Mhz when screen is off). This is unbelievable.
Anyways, here are lenik's blog posts about it:

I hope this helps other people out there!

VERY nice results! Do you think that these RIL settings should work on any network/carrier?
It's very odd because today I noticed my battery performance dropping large, BUT before it was always great. I am also on LeeDrOiD 2.1, and while at home, with WiFi + BT on AND connected to my router + handsfree, I lose only about 3-4% an hour.
Today when I left the house and went shopping, I was in the store for 1.5 hrs and I had lost near 15%! I had even turned off Wifi so it wasn't trying to scan APs. Very very strange...
Anyways, I want to maybe try these RIL settings if it will work on any carrier. Does anyone know if I can edit build.prop while in recovery, or do I have to edit it in the ROM .zip then reflash the entire ROM?
Thanks for the post and hunting down a solution slyn4ice, I'm glad that it has helped you out big time!
*** EDIT *** - After looking more into my JuicePlotter graphs, I notice that the battery life gets killed when I am using APN / 3G / HSPA network. I would have thought Wifi would take more power, but that seems not to be so. I DID have "Network Mode" set to "WCDMA only" (in Mobile Network Settings) because I heard it might save battery not having to switch back and forth from EDGE to 3G, but I guess that didn't help...I've since switched it back, but need a lot of charging before I can test again.
Does anyone else notice that when they're on 3G/H the battery drops MUCH quicker than if you were connected to Wifi instead? This is just my last hurdle towards a PERFECT ROM!
Thanks in advance all!

3G uses waaay more power than WiFi. After all, the data usually travels long distances and needs to be amplified. This effect is pronounced especially if in the limit zones of 2G/3G coverage and you have 3G preferred, the phone boosts the power to maximum to maintain 3G.
Gsm Auto (PRL) prefers 2G if 3G coverage is too low. WCDMA Preferred tries to maintain 3G connection even if it means sacrificing battery life.
If you are constantly in good coverage zones, no problem, but to the people living on the edges of proper 3G coverage it meas a big hit to battery life, especially if the mobile data is used. This partly explains why some get superb battery life and others far worse.

Amazing explanation and reaffirmation of my thoughts Jgruar (JuicePlotter confirms it). I guess from my old WinMo days, I always remember Wifi being the power hog. I actually did change it back to GSM/Auto since that was the only change I made lately, but I thought I'd chime in while my device was charging back up, hoping for a reply just like that!
Thanks a bunch!

From what I understand you need to update RIL settings in the ROM and then flash the modified ROM. I just edited the /system/build.prop file in the Leedriod zip file and saved (didn't resign or anything). Flashed the ROM through ROM Manager recovery (I also tried flashing it through the normal recovery but it failed on the "verifying image" stage - I guess because I didn't resign the archive).
As far as the options themselves - only the last two should be carrier specific. I haven't researched anything about them, so I have absolutely no idea what they actually do. "lenik" just copied them from an official Softbank ROM.
God, i just checked JuicePlotter and i dropped 1% for 1h10m (everything off except the radio + setCPU to ~400Mhz when screen off). This is just crazy ... awesome ))))

Is the setting rom specific, or will it work om opendesire?

Ok, I have awesome news! Thanks to user "lenik" on modaco forums I got some extra RIL settings (radio settings) he found for Softbank (my cellphone company here in Japan). Here are the settings:
ro.ril.enable.a52=0
ro.ril.enable.a53=1
ro.ril.fast.dormancy.timeout=3
ro.ril.enable.sbm.feature=1

LeeDroid ROM (LeeDrOiD_V2.1_A2SD+_.zip) build.prop includes:
ro.ril.enable.a52=0
ro.ril.enable.a53=1
but no:
ro.ril.fast.dormancy.timeout=3
ro.ril.enable.sbm.feature=1
Just checked.

[Q] High Battery drain on 3G / very low drain on WiFi

Hey there,
i do know that 3G draws more power since the radio for it must be constantly active whereas the WiFi module has better sleep modes (might be oversimplified a bit).
Whenever i leave the house (WiFi area) and the phone switches to 3G my battery is draining much much faster than usual. When measured, it averages to around 120 uAmps, in contrast to about 10-15 uAmps for Wifi.
I cannot understand how it can have such an enormous impact, surely there must be something wrong.
ROM: No difference in roms, but didn't try a whole lot, it's MIUI 1.4.22 R1, anyway (GB 2.3.3)
Radio: 32.44.00.32U_5.09.05.30_2
Thanks in advance,
Dennis

Your radio is so out of date, wow. Go and get this one, 5.17.05.08.
Just flash it in recovery and you should be good to go.

Thanks, I've flashed the Radio and turned off WiFi.
Ill keep the values in check and will get back to you, this might've just fixed it

Hehe lets hope so
