6 days of battery. (updated June-04)

[unrafa]

Motorola Defy 6 days with a single charge.
Connected to network for phone calls and to wireless lan, wireless sleep policy: Never sleep. Only 2g. Getting Gmail notifications 24/7.

As seen in the graph, i didnt use the phone much, just the 6th day, used it for 5 hours installing apps in the market and draining out the last 20% juice, which could possibly add more than one day and get the full week

I have China Unicom 1.11 (Froyo 2.2.1) *Now i have China Unicom 2.10 (Froyo 2.2.2) Same results.

Edited /system/build.prop and increased value of dalvik.vm.heapsize=42m
setvsel 18-300 30-600 40-800 (Underclock starts at boot to save lots of energy)
Wireless Lan policy set to never sleep (incredible but it actually increases battery life)
With stock dialer to record calls
Removed all screen widgets

I backed up everything system/user apps with titanium backup root
then i use titanium to safely remove system apps and restore some if something fails:

Removed:
VPN Services 2.2.1
Visualization 1.0
Voice Search 2.0.2
TTS Service 2.2.1
Tilemaze
Sudoku
ContactdUnconnected
Social Networking
Social status
Social messaging
Social messaging service
Messenger 6.5.0
Sinaweibo
shop4apps
QQ
News 2.2.1
News and Weather
Mobee
Maps
FOTA
Adservice
Motorola Photowidget
Landlord
Maps


I use:

Launcher Pro (instead of stock blur launcher)
OSMonitor to check which apps eats the most; and never install something that i foresee im going to use only twice times a week but starts at boot an run 24/7
BatteryMonitor widget to draw battery graphs
Setvsel to underclock
Gallery++
Rockplayer
Vplayer
Ebuddy + Mercury for msn
Sound Recorders
Colordict
SoundHound
Zedge
Etc.

None of them starts at boot and i dont use task killers,

I did some testing, the more you use the phone the more draining because of the screen 50%, radios are the next, gps, and then cpu.

The best way to afford battery is, you can't save much energy really, but the important is when you have the phone in your pocket in standby state which is most of the day, to get it to drain the less possible. When in pocket you dont need 3g, gps, or some other stuff, turning it off is good, sure there are apps in the market who does this automatically.

In my graphs its 0.5% battery every hour, in standby for 24h it drains 12%.
Other roms drains 1%-2% per hour, that is 24%-48% a day. In standby mode!!
I used barebones for a few days, and it drained 5% per hour in standby!! 5 hours in my pocket = -25% battery! or 100% in one day; I dont blame barebones, i just dont know what happened, what is sure my cpu was limited to 300mhz while screen was off. (setvsel) and i noticed no apps was draining more cpu than they should. but maybe some app avoided "deep sleep state"


1 hour duration call is 10% of battery for me with this rom. if you can minimize the drain while the phone is in the pocket, the best.

I have a theory this is possible because of the deep sleep state in this rom is working a lot better than in others. Deep Sleep = CPU shuts down for a period of time, and when some counter reaches zero (apps set up counters all the time) then cpu is awaken and it does its job.

In a Rom working well, you should get lots of this system messages (you can view then in OSMonitor.

<4>[52286.366027] Freezing remaining freezable tasks ... (elapsed 0.00 seconds) done.
<6>[52286.393585] PM: Resume timer in 42 secs (1402077 ticks at 32768 ticks/sec.)

Widgets and annoying apps who upgrade itself every 60 secs disturbs this sleep and drains more battery.

With barebones 1.5.1 i got no sleep logs at all (i dont know to blame barebones or some rogue app disturbing the phone's deep sleep) if someone notices, please let me know.

Details please

My DEFY in standby takes about 2% battery on hour. This subject is very itresting for me.
Maybe you write some details, which rom you use, what crapy stuff you wipe? What ap. you have instaled and use?

 

[eyezum]

wow 6day of using.by the way could u elaborate more on your daily usage.as my phone can last 3 day (eclair)with minimal use without play or surf.

 

[loi91]

congrats

My DEFY made it for 3 days... but I'm using it alot so I'm fine with that Had a PalmPre before and the Pres battery last for 8 h with only 2g turned on...

wow 6day of using.by the way could u elaborate more on your daily usage.as my phone can last 3 day (eclair)with minimal use without play or surf.

Almost no calls, only alarm is set, i just pick it up when i hear the notification sound for sms or emails, read them fast and i go back to my business. The last day i used it consistently downloading stuff from market and executing apps for 5 hours, to spend that last 20% (i wanted a full charge nextday) so it could have been 7-8 days.

But eclair is not as optimized as Froyo. You should upgrade to gain some more speed / battery life. And i think the most important stuff for battery life is setvsel + wireless + 2g

I first used setvsel long time ago, and noticed 24-48 hours increase between charges, and after the wireless trick, i noticed another + 12-24 hours increase in battery life. (these are aproximations because unfortunely i didn't make any test)

Automatic sync drains alot

I get my DEFY up to 3 days when I'm on roaming cause the automatic sync is deactivated. If not it lasts only 1 day with "similar" using profiles.

Does anybody know if the DEFY switches to 2G when auto sync is deactivated? I use Widgetsoid to do so.

Thanks,
hartmuna

My Defy needs charging every 24 hours - I am a low user.

My sons Defy needs charging TWICE in 24hours - he is a medium to high user.

 

[darule_2011]

6 days is pretty impressive but with no to little use kind of defeats the purpose of the phone. Right now, I am using jboogies liquidarc (which is sweet!), I use my phone regularly (phone calls/texting, wifi/internet, gps, games, etc).

I am 84 hours in with 30% left. When I first got the phone before I started flashing custom roms, I'd usually charge every night or at most 1 1/2 days in...now I nearly forget that I actually have to charge the dang thing

 

[MrBelter]

Mine has done 25% of the battery in 24 hours, it is a stock SIM free UK Defy running 2.1 and launcher pro rather than the blur launcher.

Usage over the last 24 hours is:

mobile standby 23hours 58 minutes.
phone idle 22 hours 18 minutes.
display 1 hour 39 minutes.
wifi 38 minutes.

I have used it for twitter, facebook and to collect emails over wifi only, the phone is set to 2G only. I cant recall making any calls but i have sent around 100 texts and MMS. Only widget i have running is battery monitor.

I use the app "Timeriffic" to:

-send my phone automatically in flightmode at 11pm
-deactivates flightmode and deactivates sound at 6am
-activate sound at 10am

At 10am I am awake in 99% of the cases. It deactivates flightmode at 6am so I can take a look at the LED when I wake up.

Other possibility to save energy is to deactivate vibration completely.

Very impressive
thanks for sharing

P.s
there used to be a thread where people wrote what's a must in motorola services and what can be uninstalled.

 

[zjfgavin]

thanks very much，but it's a little unblievable

 

[nepotu]

Why do you think it's "little unbelievable"? I've also managed to obtain 4 days with moderate use (around 10 hours of radio and music listening, 30-45 minutes talk-time). The secret is to undervolt your terminal using SetVsel, to remove the bloatware and set network on 2G.

 

[martin.flory]

He got 6 days because he only downloaded stuff in wi-fi. I've done plenty of testing, and what kills the battery is having open mobile data connection (3g more son than 2g). You can get a lot of extra juice from switching 2g/3g and much more by killing the mobile data connection. (widgetsoid switchers will help you with it).

Once I noticed this (I stayed home a whole day and had 90% of battery, thanks to wifi), I was happy to know that my phone was no different to those with super long battery life. That said, I think that as long as it goes for whole day without problems, its fine. And with setcpu and a blurless rom, thats easy to get.

Just find the right balance between battery life and features for you and enjoy your phone!

8 hours flight mode 1%

My Defy is charging every night , max battery life is 36h

 

[daniel_loft]

With UltraJuice on, after 48 h since unplugged, this morning it still had about 30% of battery. I charged it for like half an hour not to have surprises.

Usage: about 30-40 minutes of talking, 3G with data off (probably 2-3 syncs over the day), about 30 minutes of wireless (syncing), some 30-60 minutes of Angry Birds, etc (maybe a few camera shots, a few USSD requests, looking at the clock, searching in the agenda). Ringer at 100%, vibration on, screen on auto.

My Defy is charging every night , max battery life is 36h

same situation here

 

[IE-coRe]

I treied to use it 2 days but it was empty in school the seconed day..
noe charging every night...

 

[gkrananth]

My Defy needs charging every 24 hours - I am a low user.

My sons Defy needs charging TWICE in 24hours - he is a medium to high user.

My one too., I need to charge everyday even my call usage less......
