Hello,

I have been following these forums for a couple months now, and wow I am impressed. I love this community. I feel like I haven't contributed yet, so I started this thread. Below are my phone specs and my battery success. If this helps you, great! If you can contribute to this thread with your success, please do. If a similar thread is around, let me know; I don't want to take up extra space if I don't need to. My primary goal is for people to share their specs, usage, and battery life with Android. I had my brightness on high and 3g, GPS, and sync on (things you would normally want on all day). Peace!

Specs:

Leo - T-Mobile version

SD - 16GB class 4 (not sure brand, doesn't say)

Radio - 2.12.50.02_2

ROM - 28/7/10 Elegancia V 1.0 Final, Max Sense (T-Mobile version, if there is a difference?)

Android- 03/08/10 shubCRAFT CM6RC2/Froyo/Themed V1.1

Kernel - Cotulla 2.6.32.9#103

Info:

Unplugged at 07:30 am with 100%

Immediately checked email/XDA app for any updates (yep, I'm lame)

Standby for about an hour

Music/web browsing on Train to work (30 min)

Standby for 3 hours

Video playback during break (20 min)

Standby for 5 hours

Music/web browsing on Train home (30 min)

Home for about 3 hours with mix of standby/web browsing

9:10 pm - 15% warning (close to 15 hrs)

I stopped at 15%, because that is my "safety zone" for normal usage.

Anyone else care to share similar stories?

Before sleep yesterday, i have 97% battery, but when i wake up today, the battery left 47% :S 6hours drain 50% battery life only in stanby!!

when i checked background for what was running, Nothing..... maybe the android's screen is off, just it's not really sleep..

Hey guys, it's totaly normal, the actual HD2-Android roms are RC's, these problems will get fixed, just be patient.

My battery expirience:

8:30 - took from charging at 97% and went to work

normal use @ work (sms, googletalk, twitter and facebook)

15:00 - 15% warning

its about half the time from my windows rom, i think at current state of development it ist totaly OK.
[HD2 Android Q&A, Help & Troubleshooting and Genera] maseo:
And if you use SetCPU you can get a 1% discharge per hour in standby mode, if set up correctly :)

And what Waldemotor said, it's still in development.

Powermanagment isn't fully functioning, yet.

I'm with Darkstone Froyo 1.1 and i sync:

Gmail (push)

Exchange Mail, Calendar Contacts) every hour

Facebook every 2h

Twitter every 2h

I use SetCpu set to 245/245 profile screen off and 998/245 standard profile

I also Use

Juice Defender (paid version from market) :

With this i can plan usage of WIFI/3G :

- U can choose from push up to 5mn every 2h, i don't plan

- U can disable during night my night is from 22h to 7h

- disable if battery under 15%

- enable when i use choosed application in a list form exmple email, browser ... (keep disable elsewhere)

- U can choose automatically enable when screen is ON i don't : i prefer enable with application

Note: it's possible to control CPU too but i don't .. i think setcpu is better

- Wifi may be auto disabled when there's no access point near u

Estrong Task manager

- With this i kill all application except a choosen list when screen is off

GPS is always Disabled

With theses applications and settings i can get:

0% lost during night

and during day, my battery life depends on how much i use applications with 3G or Wifi and ... over all how much i phone :-)

Note :

I've same conf on my Htc Hero ... (Android 2.1 hect sense) my battery life is almost 3 days

With HD2 desire V5 results are not so good

So i recommend :

Darkstone Froyo 1.1 (waiting for next build)

Wirh SetCPU, Juicedefender (paid version on market), and Estrong task manager

JuiceDefender has a free version but wiyh less options but u can try it

U can control battery JuicePlotter : it draws a graph for ur battery consumption and temperature telling u if wifi or APN were enabled.

Hope my contribution will be useful for some people

A+

[HD2 Android Q&A, Help & Troubleshooting and Genera] ThinkTankInk:
Went to work with a full 100% battery, did a bit of webbrowsing and texting. It was down to 30% within about three hours.

But I'm not fussed. As it's been said, it's still in its infancy. I've done nothing to try and amend it (SetCPU etc). I just have everything running on default settings.

When things drop so far though, I just switch back to Windows if I'm not near a charger.
[HD2 Android Q&A, Help & Troubleshooting and Genera] tmihai20:
My 2 cents on the matter

I own an HD2 since last Friday, I think. I found out that it can run Android and I wanted to test it. I spent an entire day with the Android. I started with a full battery, but I browsed the market, installed a lot of applications, listened to some music, even played a few avi files. The battery is drained faster than on WinMobile, but just like it was pointed out here, Android is still in development. The main idea is that I used it a lot and the battery was almost drained in 9 hours (I also stop around 15% too). I used Darkstone Froyo 2.1 build (Dan1j3ls Froyo V1).
[HD2 Android Q&A, Help & Troubleshooting and Genera] cw-data:
- zImage 3/8, Dan1j3ls Froyo V1 (without Sense)

- setCPU enabled (always ondemand between 245 - 998)

- Yesterday 7 am - unplugged with 100 %

- Sync enabled with 3G over the day, some web browsing and playing around all day, measuring

- *#*#4636#*#* -> Phone info -> Menu -> set frequency band to Euro band, afterwards the constant 2G/3G flapping disappeared, switch to 2G only happens, when no more 3G available

- 11:30 pm went to bed, disabled Data overnight -> 50% left.

- Woke up this morning 8 am with several alarms ringing -> still 41% battery left.

With little usage good two days possible!
[HD2 Android Q&A, Help & Troubleshooting and Genera] paddle72:
I left mine at 98% before going to bed and 8 hours later (yes, I slept that long) there was 78% left...

I'm on MattC's build, German Vodafone Stock Rom (1.72...) and 2.10.._2 Radio.

However, I'm not sure if 20% or 2,5% per hour is good or bad :confused:

[HD2 Android Q&A, Help & Troubleshooting and Genera] thesweeney:
Im now on my 3rd day of using mattc v1.4.

1st day battery life was SHOCKING (as to be 'expected' (can you expect a shock???) for a RC running off an SD card).

I probably got about 4 hours heavy use from 100% to 10%.

2nd day I set up SetCPU with profiles for 'screen off' and <25% battery, disabled all data except wifi, disabled gps (tried juice defender but didnt find it useful as I never really use mobile data anyways). LEFT SCREEN AT 100% BRIGHTNESS!

This ^^^ helped with battery drain a lot and stopped the huge drain i was getting while the phone/screen was asleep.

BUT on day 2 I got a WEIRD problem:

Tried to set a pattern for unlocking - Put phone to sleep and rewoke to test lock.

The screen came on almost all white with my home screen barely visible underneath the white 'vail'.

I shutdown android and booted into WM6.5.x.

THE WEIRD THING IS THAT BEFORE THE 'CRASH' MY BATTERY SHOWED 49% BUT AFTER A REBOOT IT SHOWED 14%!

Multiple restarts into winmo and android still showed 14%/13%! WTF? I had to start charging again from there.

Now the HD2 wont charge past 91% (in android), untested in WM. I unplugged the USB and replugged numerous times - still wouldnt charge past 91%.

Left on charge overnight (android) and still at 91 this morning.

Been using it quite heavily ~3 hrs on and ~1 in standby today with lots of wifi and batt has gone from 91 to 76%.

ONLY LOSING 0.5 PER HOUR in standby now.

So basically, my battery is going nuts lol.

But so far I'm more than happy with it (considering it running from sd etc etc).

To all devs working on android builds - THANK YOU and keep up the good work. :D

Anyone else had any battery anomolies like mine? :confused:
[HD2 Android Q&A, Help & Troubleshooting and Genera] cw-data:
I also experienced wrong loading behaviour, or maybe it's just the percentage showing wrong.

The following helped for me: Reboot into Windows Mobile, there the battery loading status was display correctly as 100% (also with the status LED glowing green constantly). Then with loading cable still plugged in, boot Android, then in Android the percentage reading was correct again.

can anyone comment on the battery life/consumption with this latest kernal and 384+ RAM ?

im using zimage 08/03 right now with Darkstone froyo v1 and my battery life is pretttty bad...

it will go from "93%" (full, it wont charge over), to about 25% in 4.5 hours..

and this is making NO phone calls and on standby. I have setCPU with the settings from the other thread too

just trying to figure out a good solution
[HD2 Android Q&A, Help & Troubleshooting and Genera] kcaj32:
I'm using the CM6 froyo.

Without setcpu and without the Aug 3 zimage, my battery drain was about 12% an hour on standby.

Now, with the Aug3 zimage and setcpu, I have about 6% battery drain per hour on standby.

Win mo: stock Tmo-US ROM. 2.08 radio. (both stock). 16GB class 2 MicroSD.

I always make sure I charge when phone is either off, or in winmo. I never charge the battery on android. I don't yet trust the android kernel enough to charge my battery correctly.
[HD2 Android Q&A, Help & Troubleshooting and Genera] lemar123:
5%/h in standby problem

Yes.

Not matter what I do, and whatever distribution I'm using there is huge battery drain in stanby mode (~5%/h). I changed ROM, radio, android version (mattc, darkstone, ...). Even used winmo registry tricks. :confused:

HD2 (eu), ROM Energy, checked mattc v1.5, shubCRAFT 1.3, NexusLeo v1, ...

But there was a time I had very good results - like 1%/h in standby. Do not know what changed (except changing Android ditribution very often). The other users (a lots of them) has 1-1,5%/h in standby mode, so I'm sure it is possible. There is some kind of setting/mistake or something to discover. For now Android (even running form SD) is capable to have as good "battery results" as winmo.

I will try

- charging in winmo only

- sd format or using another microsd card

- clean Android (without data and additional software)
[HD2 Android Q&A, Help & Troubleshooting and Genera] sn8776:
same case for me as little usage (sync email few times a day manually, play few songs for kids, little browsing and market). 2 days with batteryminder. ~ 50% since last charged 1 day ago.

The one that making real different for me is when I used GSM auto (PRL) (in *#*#4636#*#*).

Also auto turn to airplane mode 11:30pm-7:00am for me.

I also applied the sdcard registry changes in winmo. seems this will take some effect also.

Post best Setting for battery life
[HD2 Android Q&A, Help & Troubleshooting and Genera] lemar123:
The solution was to

1. I did battery calibration (not sure this task was really necessery) and checked winmo battery drain - to make sure battery is not broken by Android. No, it didn't :-)

2. Charge battery to fulll on WinMo (or turned phone off), boot Android then remove /data/system/batterystats.bin .

Use this commands from Android Terminal (free).

3. Restart Android (in that moment I had expected 1%/h drain) and use battery till it come empty

Thats all. :-)

Propably, after many android switches (new distribution tests) the battery stats was broken - collected partially in different Android version.

Then finally,

after 1 week with 5%/h battery drain

problem in standby I

have 1%/h in standby again

. I think it is standard drain in haret.exe version.

My story

follow the trick on wm reg change in other threads

follow the setcpu thread, set 245-883MHz on demand... also <30% and screen off profiles... not using undervoltd...

last night charged to 100%, disable everything (wifi, 3g, auto-rotation etc), kill all the running tasks

this morning after 8 hours, I still have 97% battery! Happy!
[HD2 Android Q&A, Help & Troubleshooting and Genera] Beefheart:
I had a bad battery life on all builds (no more than 8 hours with normal use) before Shu8i's Cyanogen 1.2 which increased it to between 14 and 16 hours with normal use. Cyanogen 1.3 then unfortunately took it back to less than 10 hours but Cyanogen 1.4, as well as being the best Android build so far in my view, seems to have rectified this back to a full 14-16 hour day from my tests so far.

Ok...here is my tale on battery life...I am not sure why everyone has such different results.

I have been running Android as my full time OS since the day they solved the 5 minute GSOD issue awhile back. I was running mostly Desire V5, and recently updated to Froyostone V1 where I am happy and will stay for awhile.

Here is my setup:

Device: TMOUS HD2

ROM: Energy Anastasia (only thing installed is that android auto loader...sense is disabled)

Radio: 2.12.50.02_2

***In Android***

SetCPU

Scaling ondemand 768Max-245Min *Set at boot*

Profile- "screen off" Scaling userspace 245Max-245Min Priority 100

Everything else is default

Advanced Task Killer

Autokill when screen turned off

Power Manager

have screen to dim and shorter timout when unplugged...thats about it

I have WiFi enabled most of the time but have my network set to 3G-2G auto Gmail is set to auto retrieve and backgroud updates are always turned on for my contacts, mail, and calendar, but turned off for weather and stocks.

Using beautiful widgets with auto update set at 15 minutes and Pure calendar widget which is set to "update on calendar change"

Here is a screenshot of my typical usage...This was from Saturday, I woke up around 7:30am...sent maybe 20-30 texts...8-10 emails...about 30-40 minutes worth of phone calls

Over 16 hours and I still had close to 50% battery life left.

Edit: As you can see from the screenshot...I get pretty crappy reception at my house in the boonies. I am often on 1-2 bars and even roaming on ATT alot when at home.

I sent about 25 SMS.

I recieved about 20 SMS.

Unlocked / locked maybe 35 times to check the time.

It is normal in most of ROMS. All you have to do (the only workaroud I know) is to remove batterystats.bin (as I mentioned in one of previous post). I checked more then 4 ROMS to find out that ROMs and Radios are not the problem, but the battery stats is.

Just delete this file and reboot Android. You do not have to load battery (works from Android restart). Now I have 1-1.3%/h in StandBy mode in 2G and limited synchronization (on mattc v1.5b and about one week old kernel).

I have since done a fresh build (mattc 1.5b) and newest kernel (8/24) and drain seems good again, perhaps because these steps truly reset the batterystats.bin file where a simple delete (or rm) was not?

I have noticed that I seem to get much better battery life when I charge the phone in Windows Mobile or with the phone turned off. I think there is a problem with the battery not charging fully in android.
[HD2 Android Q&A, Help & Troubleshooting and Genera] qipengart:
Okay so far I solved my battery issue using the SetCPU program for the recommended settings of 768mhz using the on demand mode when the device is being used and then 245mhz when the screen is off. This has helped substantially.

I wish that this program were built in. I suspect that I used the Dubby(?) v9 build that battery life would be better. The Chucky Droid ROM doesn't have the robot voice issue. So for me battery management is very essential.

Does the WinMo build affect battery life as the type of Android build?

From another post:

"1. Turn off your phone

2. Charge it while its off until the "Green" led

3. Take off your battery wait for 30 seconds or so

4. Insert the battery in again

5. Charge again until you see "Green" led again.

6. Now boot WinMo

7. Startup Android

8. Go to "Terminal Emulator" (should be already installed on your android build)

9. once you get the unix prompt "$", you need to delete the "batterystats.bin" file to cleanup the incorrect statistics. to do this, type the following at the linux prompt of the emulator.

$ su

# rm /data/system/batterystats.bin

# exit

$ exit

"su" will give you super user access rights

"rm" will remove the batterystats.bin file

After the above, reboot your device again from WinMo and charge to 100%, then start android. You will see 100% :)"
