Battery Drain

Hi All,
When i look into (almost) all roms i see the problem with the battery drain problem.
To bad i do not have the knowledge to find out what to do.
But i think that some smart developers work together to find a solution about this battery drain problem.
So that's why i start this thread so we can discuss this

AdamG's Official Froyo HTC Sense might hold the key to this since it seems to give about 2 days battery performance with the original battery unlike any other rom.

Thanks, but i don't like the interface.. want have the sense feeling

Drain
Tested a lot of roms with froyo and sense. The roms based on 2.06 base are draining relative more then the roms based on 2.04.
Above is not scientificly tested.

Charge to 100% , go to recovery , advanced , wipe battery stats. Enjoy greater baterry life

I had NONE battery drain problems on any of ROMS 2.1 or 2.2, and i did try alot of them.
Maybe theres something wrong with your phone itself (battery).
But definetly try wipe battery stats in recovery.

Since 08:00 morning had WiFi on.. network Data of... and now 12:02 battery is now 90%. DId have play with config the Tasker Tool (Great app).
Tomorrow i will do the test again but then with Network Data on and WiFi off.

people are having mixed results on the battery perfermance of adam's sensefroyo rom. i experienced a poorer battery life compared to eclair (i used Amer_v4 and the battery was excellent) but can still manage to last a full day usually. haven't tried out the froyo roms though.

btw aren't you're using opendesire?

I've changed about 8 roms, mostly used 4, but can't say there was a huge difference between them. 2 days of normal use, 1 day of heavy use.
Possibly shadowfrost and DeFrost 2.4 had the best battery life and I had the fastest kernel installed...
I would think that - some isolated problem aside - mostly it has to do with some applications/settings

sometimes my E-Mail application is consuming most of the cpu. It keeps the cpu at max frequency. Even if i try to end the taks with the app "system panel" it wont solve the problem. I have to go into the app and make a manual sync.
i also found out that automatic brightness is using loads of battery. since i set it to static I'm experiencing almost 2 days of battery life with moderate use.
I'm on Defrost 2.1

Hello again everybody,
Yesterday whole day online by WiFi. Using phone couple of hours and my Maildroid Email was active without prevent sleep mode.
Battery was empty after almost 17hours. (+/- 5% every hour)
Today. Wifi on. Maildroid now with prevent sleep mode ON.
Have unplugged the phone 4 hours ago and battery is at 75%
Tomorrow i will test this with Network Data on.. and without prevent sleep mode of Maildroid. And day after with prevent sleep mode.
I know for sure.. the battery will drain very vast for both situations...
BUT Ill let you know
EDIT 26-07-2010: Battery was empty tonight on 1:30.
NOW I do the whole test again but now with network data on and WiFi off

Ive had the opportunity to own a Nexus One at launch and a HTC Desire...I always found Android OS to be the issue whenever i had excessive battery drain.
Ive found my issue to center around the OS 'calling home to sync' (whether 'sync' option is selected or not)Initially, the problem was resolved by deleting all my sync funtions...but that was obviously not practical........ so now I keep my GSM data connection running and I get about 2.5 days on Open Desire (non HTC Sense).
AdamG seems like the guy who knows what hes talking about - His changelogs for OpenDesire actually hint at him having done some battery drain tweaking...whatever he did, he has definitely fixed it
Cheers

I've tried so many ROMS in the past few weeks to try to solve battery drain issues. On some, I could almost see the percentage dropping as I looked at the home screen! I even bought a new battery thinking I might have killed the original.
OpenDesire does seem to be the way forward re this problem if you're intent on the HAVS kernel. OD2.3a gave me almost two days of varied use.
However, and I know this is going backwards, an earlier DeFrost - the 2.1, is brilliant for me. I'm now at two days since unplug and still at an unbelievable 45% - yes, I know, I thought it was broke as well! For now, I'm sticking with this one. Everything I want works and I don't have to carry a spare battery in my pocket when I go out.
Hope this is of some help. Don't despair. You will find the one for you.
Cheers

I don't get why everyone says they have such a issue with battery.
I get about 2.5-4 days of use with DeFrost 2.2 and have done about so since DeFrost 0.9. I've had it up around five days once.
How are you actually using your phones?
It's not a "Froyo" issue.

It's very interesting to me how are YOU using your phone?
Come on, 4 days ? When i talk about 30m to 1h each day and using a phone little bit, i have at least 30-40% down.
u mean u only drain about 25% each day? are u actually using your phone ? wifi, calls, 3g ? or u have a expensive pocket toy just to show to your friends ?

i'ld say any rom with SetCPU will have decent battery...
i drained 20% of battery in 27 hours with regular (short) usage at work

i'm not convinced by setcpu. i surfed for 20 minutes this morning and lost 10% battery life ..

Set CPU
I found that with set cpu running on leedroid if I set any profiles then i struggle to work even though the only profile that is active is the screen off profile.
It's like the moment I turn it on it causes issues.

[Q] Battery lifetime on official OTA Froyo ROM release?

Hi
Any news on how long battery last on the new official release?
Im currently on Pays ROM, and battery last between 24-48 h, with 3g and wifi turned on and daily use of phone, sms and browsing.
Just tried some ROMs that didnt even last a whole day

In 3 hours I have nearly used 50% of battery and that is with 3 short phone calls.
System, cell standby, wifi and phone idle account for 80% usage. Was using a different froyo rom before putting oem one on and did not have this type of drain.
Also not using an app killer as people have been saying that the system can handle the apps, that has not been the case and will install again.

My battery drain has been up massively since I went to 2.2 with the OpenDesire ROM. Phone standby takes most of it. What's causing such excessive usage? Even on the official ROM now :-/
What ROM's are you guys getting best battery with?

You should post on which ROMs you have the battery drain...

I have had massive battery drain on all ROMs until I started using the rooted 2.2 OTA. I would have to charge my phone twice every day but now it's great, I have 65 percent left after a full day of heavy use.
Edit: tried almost every FroYo ROM before this.

Which ROM are you using? I can't decide which one to download
Battery life is also my only problem with this otherwise amazing phone

Maybe it's the rom/radio combination!?

I had PaysDesire v2.3 before installing the OTA 2.2. The battery with PaysDesire with average use went from 100% to like 60% in 12 hours. With the latest one, i lost 8% in 2 hours but with over average usage. Testing the camera, installing apps, setting up things...
That is why I am still not convinced that the battery sucks on 2.2 and I will wait few days (until the shine wears off, as Coldplay would say) before bringing my final decision.

Doesn't you guys' phones' display use most of the battery? For me it's at least 70% of the battery usage.
With SetCpu I use about 1% battery on standby, but as soon as I use it, it drains battery like crazy, even though the brightness is set to 25%...

I am using this one http://forum.xda-developers.com/showthread.php?t=741775
I took it off charge at 7 a.m. an have used it quite heavily today and the battery is still at 50% so I am pleased.

8 Hours and im on 68 %
2 Hours 3D Gaming and browsing 1 Hour.SmS/Few Calls between.
Official 2.2 Froyo ROM.
Wait for Kernel Sources and i think Battery Drain will fall and fall =)

that aside, no rom or os version has changed a fig for me about battery. It's still good in reasonable terms.

+1.i am getting really good battery performance on this ROM.
but from my experience even from WinMO you will never find a single ROM on which people would agre on 100% that is good or bad.everyone is getting different results.everyone has different apps instaled,using different combination of services (push mail,wi fi,3G...).
Someone will always claim good battery life and others will say it is crap.this is really about testing what works for you the best.
Sorry for my english guys...

When i have a good connection then my battery is ok. After 16 hours i have still 12%. If my connection is bad (i'm in a building) so it search for connection and lost it again i see the battery drain and my battery is empty after few hours...

Rom w/ Best Battery Life

curious to see which ROM you experienced the best battery life with. I am not a big flasher but used darkside v8 and CMX and seems like v8 got better battery life. Mainly a web browser, email, pandora. not big on games. what has your experience been like so far?

Nothing wrong with stock ICS (if you tune it right). No need for CPU sleepers scripts or something like that if you keep you phone clean from sloppy written apps.

Wow dude can you give me some tips on how to get this type of battery life. I'll kick CM9,CM10, AND AOKP to the side to get half that production. The best I've done is 30% after 28 hours hitting Youtube pretty hard .

Lol, that can't be the answer I like using Jedi Mind Trick, I'm getting far better battery life than when I was on the Darkside Rom, even with tweaks.

Jedi ROM is rocking. Beutiful with battery and really fast

whick kernel are you guys using with jedi? faux 006 or faux 007?

Why even have a phone if you don't use it? Out of 96 hours you used it for 1 hour, thats like 15 min a day. That's not showing good battery life of usage, it's showing battery life on standby

You right. I was experimenting those days. Besides it was 30 min per day - 15 min of screen time (checking email and reading news) and 15 min of voice call.
This test also shows that there are no rough apps on my phone which could eat battery on background. And the ROM is pretty stable. What would be your results in similar scenario?
If you have read my posts - one day I had 7:40 hours of screen time (was reading ebook) and had 40% battery left. This is another type of usage.
So power consumption is vastly different depending on type of usage... if say you are looking YouTube through 4G your phone will be dead in 2-3 hours...
I have posted results of power consumption during different type of usage so one can compare more objectively and not against "OMG this ROM/app are so good" statements.

Don't have any stats to prove it other than experience but after a few hours on Jedi Mind Trick I can already tell it's being great on battery compared to any AOSP based ROM and it's SNAPPY fast! :thumbup:
For some reason it reminds me of the Darkside GB based ROM Digital Warfare (this thing was crazy good on battery!).

Used almost each n every Custom ROM... tiLL now max of 14hrx :/

Too many x's
It's perfectly normal for wi-fi to consume that much. You won't get any better battery life than 24 hours.

like abaaaabbbb63 said, too many variables. only way we can answer that is for you to tell us what you do on wifi (browsing/streaming music/email), and how much time on you are expecting...
time on wifi will last a long time if you have good signal, not syncing anything, and screen is off
biggest consumer of battery should always be screen if you're actually using the phone, so keep brightness low if you wanna save battery.
new kernel might make a little difference, not going to double it or anything, have you tried searching for it yourself?

I suggest using battery monitor widget, it shows you exactly how much you drain your battery in all situations...so you can watch it closely.
regarding recommendations, MildWild roms in my experience are very "battery effective"

just one info; MW roms in standby consume cca 5-10mA of your battery (you can see that with the battery monitor widget) which is 0,7% to 1,2% of your battery in one hour (on my 2 year old battery, which lost cca 20% of initial capacity)...which means you can have all connectivity enabled all the time (email, whatsapp, viber, etc.), and in "clean" standby your phone can live up to 100h.
and that is the max as much as I saw, that can be achieved with old 1400mA, stock battery.

Can u post a screenshot? This is how my history looks like... You can see during standby, it consumes only 5 to 6 mA (from 10 to midnight to 12:01).... Did you calibrate your battery? How old is your battery and does it shut down on 1%-5% or more....?

Well... If battery is well calibrated, it shoud shut down at 1-5% max... Not 25.
For monitoring your battery, you can use batery monitor widget from the store, this is pic from "history".
For good calibration you can use battery calibrator nexus (for desire, yes) and follow the instructions. If your battery dies at 1-5%, you calibrated it right...

Using battery calibrator (Nexus)
Unable to calibrate b/c in "LEARN MODE" 3416 mV min. required for that.
& battery dies at 3500mV
@history....can't find that tab :/ .. even using spare parts it simply showed the stuff "attached pics in 2nd/3rd post of mine"

Well.... That could point out why you have such short battery life with any rom... Your battery is almost dead.
