exec battery performance

my exec battery doesnt last very long.if i fully charge it then turn the phone off,the battery is dead flat within 24 hours.and thats when i dont use it at all.
the only way i have of charging it is with a USB cable.
is there something i,m doing wrong?

try turning on flight safe mode when not in use that tends to save a lot of battery life

I left my Universal in the closed position at 47% and two days later returned to use it. It still had 45% battery life. This is with bluetooth turned on (I never have it turned off).
I hear WiFi is quite a battery drainer, make sure you have that turned off. I don't use WiFi (Only GPRS) so I never have WiFi on.

Hi DavidT. may i ask what ROM you're using now. my phone only last for about 6 hrs max. without any use. NO BT or wifi on. thanks.

I'm using O2's 1.30.107 WWE ROM.
I decided to test again last night. Left it at 89% in the closed position approx 10:30 pm, opened her up this evening at 7 pm 87%.
If I constantly use it, I only get about 6-7 hrs of combined phone/gprs/pda usage out of it on the regular battery. On the extended battery I can use it for a few days

make sure that there are no background programs running. It should run for almost 3 days without use in that mode. If you let some IM running that it won't last for more than 24 hours

ok, there are a lot of forums on this topic, and a lot has been identified.
I am at the moment using Ivans AKU 3.2 Rom, and this is a great battery saver. Not sure the tweaks used, but here are some additional suggestions:
1. Turn screen off after 2 minutes
2. Turn device off after 3 minutes
3. WIFI auto off after 2 minutes
4. Disable bluetooth when not in use
5. Turn off beam auto receive
6. Turn off error reporting
7. Remove anti virus
8. If you dont use UMTS, disable and switch it to always GSM
9. Ensure active sync isnt constantly running
10. Use GPRS only when you have to
11. Wind back the screen brightness on batteries to the very minimum, just before it blacks out.
12. Try to minimise the number of SD card read and writes (ie today screens, memory card readers, icons linked to SD card)
With all of this, and only general phone, PDA, and WIFI usage occuring sometimes during the day, I could get upto 3 days on Ivans rom. But usually, on the imate rom about 1.5 days.
If I use all of these non-stop constantly all day, it will be pretty drained after 1 full day.
It has occured in the past, and I dont know how or why, but something was running, and within an hour or two, battery was completely gone.
I couldnt fix it, so I hard reset and it didnt happen again. I suspect some programs get themselves into an endless loop (eg Activesync or others), and perhaps reading memory cards, etc caused it dont reall know.

how can I kill the ActiveSync process?

Take a look here for tips and a great write-up on power usage...
http://blogs.msdn.com/windowsmobile/archive/2006/08/04/689069.aspx

I am unable on ivans to kill it fully, always comes back.
on older roms, try
1. open activesync
2. add server source
3. enter any dummy entries
4. set schedule to manual
5. delete server source
6. reset
if u use push email, this won't work.

Battery live

Hi
Yesterday arrived my dev phone 1 and I am very hapy with it bu battery level is at 20% at 18:00. Is this normal?. I dont want to switch the band to 2g. I keep gmail synched with direct push but google talk not. anyone with same prpoblem?
Thanks

yeah, the standard battery in the G1 is ****ing terrible
not a lot you can do except buying an extended battery (which is a very good idea! )

The only thing I have found to extend my battery Life has been discussed previously a few times on these boards...
1. Turn off Wifi, when not in use. (Toggle WiFi from the Market is Great)
2. Turn off GPS, when not in use. (Toggle GPS from the Market also great)
3. Turn down the screen brightness.
4. (not sure if this makes a big difference) But sometimes if I do not need my feeds or background running apps throughout the day I will restart my phone, or run through a few applications that are not pulling web cache. This way you dont have auto update feedreaders in the background running. It seems like it works for me, but that could very well be wishful thinking. Also turning of things like Twitroid update etc...
Hope that helps.

i do #4 as well, it seems to help, since i have root i just go into terminal and type su [enter] reboot [enter] and when it turns back on its usually doing bettery with the battery
as for opening programs, would advanced task manager serve the same purpose (closing apps that arnt needed and using memory, because if its using memory isnt it in some way using battery power?)

Thanks.
I am porting CommMgrPro to Android (Similar to Locale but much more powerfull). In this way I will switch to 2G, turn Wifi off, disable connections, etc, etc, etc automatically depending on my location/weekday/hour.

Hi All
I have a brand new G1 and, like you, I was suprised by the short battery life.
I also thought about selling the phone but apart from that problem I like it very much.
I noticed that the permanent 3g wireless connection was the real draining battery application.
So the solution I found now is: to disable the permanent connection. I downloaded APNdroid application from the market and I use it everytime I need to toggle connection on and off.
I also tried to leave the WIFI on and i saw that it does not consume much battery.
I did not tried with the GPS.
I am using a good tool to toggle and to fine check the battery level: Useful switchers
I can now say I am pretty satisfied with the phone.

Yes. It was the same problem there was in HTC Hermes/TyNT and TouchPro/Diamond. I created bandswitch in the past and will create two little toggles to switch 3g/2g with and without time limit....

Conditioning
Try Conditioning the Battery...
I have gps on, 2g, brightness at 50% and screen timeout at 30 secs, everything syncing and I get around 5 or 6 hours of use...just like the company says I should.
Run your battery completely dead...
Charge your phone for around 8-12 hours...
Repeat for about 6 days...
You should see improved battery life.

I have 3g, wifi, bluetooth, brightness at 50% and screen timeout at 30 secs, everything syncing with 1-2 hours of music/video with 30 SMS, about 20 mins of calls......I am now getting about 8hrs on the new ones from HTC (the 04).

Interesting Battery
Well now that I have had a week of use I have noticed that the (old) "02" batteries would last about 4-5hrs and go until 1% before turning off, with a slow count down. The (new) "04" batteries stay at a high number (about 6-7hrs) until they get to 15% and within a few mins turn-off....as I recall I saw postings of 'quick' count downs, so I wonder if you either get a slow drain down with about 4hrs of use OR about 6 hrs of use with the last 15% a very quick shutdown....I'll keep monitoring these new HTC batteries to see if it was just one of those "weekend" things or if this is the trade off...was caught off guard as I had been getting 30 mins or so when I had 15% left and the G1 would stay on until 1%..."teach an old dog new tricks".....

what is the most energy saving rom?

I am using Duttys leo HG V0.8 WWE and whilst it is a good rom I have to charge the phone every 6-10 hrs and even more if I use a juice hungry app. What is the best life/charge that anyone has had using what rom?

I have tested few ROMs for now and all I can say .. CleanEx is the most efficient for me and my battery. Try 1.19 UltraLite Turbo. The point is it has most of junky apps and visual effects removed so you put inside the ones YOU really really want via cabs. ROM as core as possible. Simple.
P.S. It is not commercial, just my own experience

Many Thanks, what sort of life are you acheiving?

Turn everything automatic off or pare apps down.
I took my TP2 from less than 12 hours to 4 days doing one thing; turn everything automatic off and run manual. Turn location service, weather...off. I don't need the Twitter app running; I have it setup to SMS text me and I receive tweets as text messages. Over in Wi-Fi set it to best battery and over in back light drop it down to 60 percent and even lower while driving at night and set it to turn off the backlight after one minute as low as 30 seconds and off after a few minutes. There is tweak in B&B Tweaks for power save mode which I believe turns wi-fi off while it's in sleep mode...I set my email accounts to run once every 4 hours and my Google mail to run once a day. There is so much information on our devices that requires the device to literally always be in contact with our providers and now I know why it requires a data plan. So many apps are tied to it.

Like SnittyKitty said, I have disabled all `automatic connections` OFF, everything is on manual. When not using data connection - always switched into 2G mode, at home only Wifi.
Battery life ? Some news reading (RSS hub, web pages), mail ... few times a day + some txts + some voice calls ... about 3 nights and days to make my battery flat, sometimes 3-4 days, depends.
Last week I was testing my battery by running internet radio (Miasto Muzyki from OpnMarket via data connection over 3G). It took about 9% from battery life for one hour of listening.
Kris

It could help to make it a habit to carry a spare battery in a case.
I have a form fitting plastic case for the spare battery, and it goes with my phone everywhere. It was annoying at first, but now it's a habit. I don't end up needing it most of the time. But it definitely saved me few too many times.
I am thinking about buying the extended battery, but........I like how thin the phone is...
sigh...

As said before. set all to manual or about every couple of hours. use bandswitcher to close your data connection
look here to see what power consumption is used for what service. you can decide yourelf what you are using and what effect it has on batterylife if you switch it off.
http://forum.xda-developers.com/showthread.php?t=632684
at the end you should be able to get a good battery consumption on every rom.
i have use different ones and always managed to get a 2 day+ batterylife

Battery drain problem

I am using CMN 6.2.0 v2.0 with radio 2.15.## (can't remember the other numbers). In standby, I get somewhere around 2-5 mA (according to current widget). My battery drain in an hour is around 8% in standby. From what I can tell, this is not ordinary. My display is set to the lowest brightness settings. What I am syncing is my facebook (every hour), gmail, google reader, contacts, calendar, launcherpro facebook (every hour). If I am actively using my phone, it'll lose like 25% in an hour. I have MAGDLR 1.12. This is about the same battery drain as when I used HD2One for the SD card. What am I doing wrong?
Update: I do use Titanium back up to restore apps, does that have an effect on battery?

no answer, just some tips.
First, do not forget that battery drain is subjective (it's directly link to your usage of the phone).
I don't know your ROM, NAND or SD?
try to switch of things one by one:
Start in flight mode (check drain),
switch of data (keep only phone),
activate data but stop the auto synch of all your stuff,
put them on, one by one.
(do you keep wifi on?)
It will also depend of the strengh of your network. The weaker it is the more power your phone will use. If you're between two cells it can keep switching from one to the other.
I'm using Gauner NAND and it impressed be. In flight mode I loose around 3% over night.
Let also some time to your phone to "stabilize" after flash. Don't know why but after fews days my power drain has improved a lot (battery calibration maybe?).
hope this will help you.

My ROM, NAND is in my signature. I have put it on airplane mode from 2am-7am which it only lost 2 % (so im guessing it's something to do with data/sync). At home I use wifi, at school I use data. I will try turning off 3g and i'll try turning off sync. But the only thing I ever sync is gmail, contacts, calendar etc. I will attach my app list. I already read that URL and have done it many times, still lose 8% an hour.
HTML:
http://www.appbrain.com/user/jasonvvong/1-22-10
For all these people that claim to get 2 days out of their hd2, do you turn off 3g or sync or put it on airplane mode? If so, doesn't that really defeat the purpose of the phone? If you have to turn off imperative functions of the phone to have it last longer that 12 hours (that's how long I get with my phone), it seems pretty counterintuitive to have a smart phone because when I need to check my email, the internet, etc, I can just walk to a library or a computer lab and look at it there. It defeats the convenient nature of a smart phone.

At least in flight mod it seems ok
I have data always on, but when I install my ROM I setup to NOT auto synchronise. I prefer to know what my phone is doing. I'm not very good (yet) with Android but a lot of things seems to work in background.
I check my mails, use phone and it last more than one day without any problem.
Try to disconnect the auto-synch and activate the sync only for what you need (for me just mails and stock), use the smaller frequency you need. No need to update your mail every 5 mn if you check no very often for example.
Sorry but no other advice. just try to isolate what drain your battery.

When I read this "But the only thing I ever sync is gmail, contacts, calendar etc." check the frequency. If it's very often and with a lotof data, it could be a heavy usage.

Go to settings, about, battery use. That may help identify if there's anything chewing your battery up. I suspect that it will show the display as using the most power, which is normal and not really much help. Worth a look though.

Juice Defender and Battery enhancing applications

Any positive reviews with Juice Defender ? I had it on my phone and used it on the extreme settings but didn't notice any difference even though it say it has improved my battery life by 1.68 times.
How do you make it really work ? Any tweaks and suggestions are welcome.
PS: Are there are more battery boosting applications out there that enhance the battery life ?

Is there any battery life boosting app that works?
I don't believe all the hype.. It runs in the background, so the apps itself is a battery drainer..
Sorry, but for me, lowering brightness, turning off 3g and mobile network when unused and also turning off haptic feedback helps increasing my battery's charge..

Of course these apps work. They turn off all radios when the screen is off, so, of course, they save battery.
Have you used this baby with radios enabled and the screen off? It gushes battery. With Juicedefender it looses very little battery when you're not using it (I should point out that the app will occasionally switch on the radio to get updates).
I recommend that you let JD manage your data and wi fi connections. It will intelligently use the radio that best saves battery. After some training, its like magic (it trains itself).
I've used several battery savers and I like Juicedefender best. It permits you to actually use the phone without disabling every damn facility and still get a day of use out of it.

Tried it once but use Green Power Battery Saver now, much prefer the easier UI
If rooted, along with LeeDrOiD 1.5.0 my battery life is amazing

I turn off wifi when I'm not using it, but 3g is too much hassle and I suppose I do struggle to get much more than 24 hours out of a single charge but gushing battery?

I think the phone does this without the help of additional apps. I'm losing only 1% per hour on standby with 3g enabled and auto sync. I did nothing special to the phone and I have no "battery saving" app. Does it, practically anyway, get any better?
Cheers from my DHD.

You get 100 hours out of this phone with 3G enabled and auto-syncing Facebook, Twitter, etc? You must have got one out of that batch of super-phones that HTC accidentally produced.

I'm trying green power at the mo.

What settings do you use for green power?
Mine settings:
Managing wifi and mobile network
checking traffic (0,1kB/s)
Starting at boot
Day Mode:
07:00 - 22:00
On 10min - Off 10min
On if power ON
On if screen unlocked
Night mode:
22:00-07:00
On 1min-Off 8h
On if power ON
On if screen unlocked

I don't see the need to use stuff like this. I unplugged mine this morning and I still have 85% left with some moderate use with Facebook on push, weather and e-mail on 1 hour and others on once a day or update when opened.
I should point out I am using the Cingular radio and Android Revolution HD 2.0.9 but even when I was on stock I didn't have a terrible drain unless I had HTC Sense syncing away to itself. That seems to be the key issue.

You may be missing the "on standby" part of my post that refers to the one made by another poster. The point is, I think the phone already disabled unneeded functions without the need for an app. My phone doesn't have unbelievable battery life, but it doesn't suck either.
Anyways, I think "battery saving" apps just end up using more power.
Cheers from my DHD.

I have dissconnected phone from computer on Sunday 7 pm. Started Juice defender. About three hours of reading comics, about 30 minutes phone calls, email few times a day and some internet/market (about 1/1.5 hours) and on Tuesday, 2 pm, I still have 34% battery. There was some music playing for about an hour and video clips for same time. Great result in my opinion. I think Juice defender works great. At least very good.

JD is alright, its not stellar but it does help (for me and my settings and usage). It will help a lot better if you purchase Ultimate Juice, that's when it starts to be interesting but that's the thing, you'd have to purchase it before you discover if its the best solution for you.
I don't think there's one app that will universally make our battery life better. The apps will help if you could make its functions play well with your settings and style of usage. Short of saying that if you find an app that will enhance your battery saving habits and capitalize on the opportunities that your phone can save power, then that'll be the best option for you...
JD is alright, UJ makes it a lot better...

It looks like it is better solution then buying extra bettery. Good job. I am gonna try it for some more time and if the effect will be the same I will get the UJ. Thanks.

No, I didn't miss that part. This phone does not drain at 1% per hour with 3G and syncing enabled - in standby or not in standby. It just doesn't. And there are newbies reading this forum who might believe your figures.

It does. I sleep for 8 hours, I lose 8%. I think its supports the argument that the phone only uses resources when needed. Since it doesnt sync the entire time and only when its scheduled to, I dont see this is as an impossible figure.
Lets try to remember the context comments are presented in this thread.

Android Assistant 2.2
Hi all, I would like just let you know, I tried a lot of apps for improving battery life, incl. Juice defender, and I must say the best one I tried is Android Assistant 2.2 build 15, after few settings I can say is really the best : full auto sync on gmail + company mail + weather, screen on 10%, screen off after 30s, gsm only, mobile data always-on, playing tank hero and few more games couple times a day, phone calls 30 - 45 minutes per day, 10 - 15 text per day, GTalk always on - and using quite a lot, wifi is on from 7.00 pm till 12.00 am, vibration always on, and result Full 2 days without any problems and overnight no any limitations, if I am using limitations overnight and not playing so much, and no wifi, battery will make easy 3 full days...
