What's the best battery settings for stock rom? - Epic 4G General

I keep seeing all these threads about how people are getting rediculous hours on 1 charge, but mostly all the post I see are people with rooted phones. What are the best ways to increase battery live on a epic with stock rom?

Those crazy battery life u see is ppl putting their phone in airplane mode and with very limited use. They don't mean anything. But some tips to improve batt life are keep screen brightness down, turn off 4g when not in use, maybe use juice defender to automatically turn off 3g whenever the screen is off.
Sent from my Epic 4G

I'm 100% stock, unrooted.
Turned off Auto-Sync
Brightness set to auto
Wifi on, since I'm usually within range of work or home wifi
Swapped Wifi policy to never drop when asleep. (prevents wifi from dropping and going to 3g)
Killed that absolutely stupid DRM process
Activate Airplane mode after initial boot and turn it back off. (Due to Samsung bug)
Have any program that syncs set to sync at 2hr intervals
My battery life with heavy usage will last over 6 hours (games, txts, browsing, app downloading). With moderate usage it usually can go 15 hours (sans app downloading), and with light usage I've pushed it 2 days (games and txts).
Mind you I don't use the browser much since 90% of my day is in front a PC, Mon-Fri.

I'm 100% stock, no root as well.
1.Train your battery!
when I got my phone I did at least 3 full charge/complete discharge cycles
2.I do not use any Task Killers or JuiceDefender (tried and uninstalled for ineffectiveness), I just use built in tool to monitor running programs and kill off the one I do not need. I prefer not to install application that do not have clean exit programmed. I do use JuicePlotter to monitor battery charge/discharge.
3. After each reboot toggle airplane mode on and off(Airplane trick)
4. Go to Menu/Settings/Applications/Running Services and shut down all services that not needed (DRM, MediaHub, etc)
5. Set brightness to minimal possible value (works fine for me), not auto set - when I need it on the street just slide the finger across the status bar and raise the level as needed.
6. All 4G, GPS, Wi-Fi are off and on only when needed. I use Wi-Fi home, 4G at work, rest of the places 3G or whatever is available. My data/sync is always on. Wi-Fi set to never sleep.
7. I have Roaming Guard off since my house in the very poor reception area so it's roaming most of the time but there is wi-fi for data.
8. Use dark background/wallpaper (I use Star Wars light speed jump live wallpaper)
IMO the battery life is depend on the type of use. From my 2 month experience the following battery killer tasks are:
1.Streaming video, music with screen on (will discharge the battery even when plugged in.
1a.Streaming music with screen off.
2. I haven't tried tethering (hot spot mode) but would think it's a killer as well
3. Browsing web, especially over 3G
4. Roaming
5. Game playing.
6. GPS
Obviously you can have a bad (defective) battery, but it's likely less then 1%.
Good luck!

nikon120 - What do you consider moderate? I consider my usage to be moderate, but I can't go 15hrs. Yesterday after fully charging the phone from mid point, my phone completely died after 5hrs, with very light usuage as most of that time I was busy. Today with light to moderate usage, my phone is indicating that it needs to be charged at roughly hr 10.
stud_muffler - I'm not familair with this airplane trick you're referring to. Can you enlighten me?
I'm doing most of the things suggested in this post, but I still don't think the battery usage I'm getting is up to par. The battery life on my Epic is much worse then what I was getting on my WinMo TP2, with roughly the same amount of usage.

After you reboot the phone press and hold Power button until it buzz.
Menu will appear.
Select and touch Airplane Mode option. It will turn off all radio and show plane icon in the status bar.
wait few seconds and repeat to turn radio on.
that's all.

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".....

Terrible battery life

Hi -
I've had my HTC HD2 a few days and although I'm happy with it's features, I'm really frustrated by the poor battery life. The first day I used it the battery was dead within under 12 hours from me starting to use it, and at the start it was fully charged. On this first day I did have email and weather etc on auto check though.
So last night I disabled weather, set email to manual checking and disabled a few other things, but did leave HSDPA and 3G on. There was a slight improvement today but not much, the battery lasted the full 12 hours, but with only 2% remaining.
Both days I don't think my usage was very high. I'd maybe had 10 minutes of phone calls, sent around 10 text messages, listened to 45 minutes of music, checked one or two websites, and played games on the phone for about 15 minutes. Imagine how it would be when I need to make several calls in a day.
I have searched the forum for tips on improving battery life but the main suggestions seem to say that I should disable HSDPA and 3G but one of the main functions of the phone is internet usage and I don't see why I should how to switch to manually putting these settings on and off each time I want to use the internet, just so I can get a longer battery life - the battery should be able to cope with moderate usage!
Does anyone have any further suggestions?
Thank you
Look for an application called 'Bandswitch', it can disconnect idle connections. THis way 3G won't be enabled when you don't need it, should save some battery.
Disable automatic screen brightness and set it to something like 30%.
Disable location services and stuff.
Give the battery some cycles to reach full potential.
But of course, gaming, internetting and listening to music will drain the battery faster. It lasts about 2 days for me with moderate use (some internet, some playing around, etc) which is pretty fair imo.

I'll give that a try. So will it automatically enable it when I start browsing the internet or something?
I already changed the screen brightness and disabled location services though. That didn't seem to make a big difference.
And how much difference does giving the battery some cycles make?
Thanks.

Sorry, but it doesn't work that way
Bandswitch can definitely do 2 things- it can disconnect idle connections, which will reconnect when needed, but this won't switch the transport between 3G and GSM, and has little effect on battery life
Or it can be used to manually change between 3G and GSM, using whichever is selected for its current transport and then autodisconnecting if required. It is the action of switching to GSM which has the most impact on battery life, but there is no way to switch automatically between to 2 as it needs a phone radio off/on to execute the switch.
Poor 3G signal conditions will hammer the battery because the phone will continually hunt for the strongest signal and switch constantly between modes. If your 3G signal is less than 2 bars I'd suggest switching it to GSM until you are in a stronger signal area. Do this by going to Phone/Menu/ then scroll down to Band and from there switch between Auto and GSM. If that makes a difference then you could install a small utility to make the switch easier to access.
seems very odd, mine was fully charged around 11pm last night, have sent around 20 texts, 20 mins calls, had wifi on, done some browsing, abit of sat nav and its on 68% 20 hours later.
I get at least 24 hours with moderate use. Most of the time i get around 30 hours.
I have weather and peep updating automatically + email retrieval at every hour.
When I first got mine it was lasting less than 12 hours too.
Now I'm on ROM 1.61 and have the following settings:
HSDPA disabled
Weather update every 3 hours
Twitter updates ever 1 hours (though it actually only updates when I scroll to the Peep tab)
Facebook auto updates - Off
Stock auto updates - off
Bluetooth and Wifi off unless needed.
Screen brightness - 30%
Haptic feeback, Vibration - off
Push Email - On
I'm getting over 24 hours of life out of a full charge now. I have got the push email set to manual updates only during off-peak hours ie when I'm sleeping. During the night the charge drops around 1% per hour. It was at 47% when I went to sleep last night and was 40% when I woke 7 hours later. This seems to be typical overnight drop for me.
Over my first few days of tinkering and setting up I found the battery drain to be massive. Once you settle down to regular usage it is a lot lot better.
However, just to be careful, I do now have a desk cradle at work so I can charge my phone if I have to.
Prior to my most recent hard-reset I found that if I left the phone in stand-by over night, with it checking for email every 5 minutes, and weather every 15 minutes, the battery would go from 100% to zero in less than nine hours. And that's without using it at all! As an experiment I tried turning off everything that could possibly be using the data connection, and turning off 3G, so nothing was running at all except the phone in 2G mode listening for calls and texts. It still burned 20% of the battery overnight in stand-by.
Since doing a hard reset, if I repeat the second experiment then I find that overnight battery drain is now only 4% - so clearly some piece of software that I had installed prior to the reset was hammering the battery even in stand-by. Quite what it was, I'm not sure yet. (My current prime suspects are the task manager and 1% battery status icons).
If you're having battery drain issues then I suggest doing a hard-reset and then not installing anything remotely controversial for a day or two to see if that sorts out the drain. If it does, then you can start reinstalling things gradually to see what difference each one makes.

Oh, I misunderstood it then... thank you for clearing that up!
It's very interesting, to see the number of people who have battery draining problems. I have the french SFR ROM 1.44 and since the beginning found my battery life satisfying (I didn't expect long life, as my wife has to charge her iPhone every night).
My battery lasts in heavy use 24h (though it can go down to 18h when using internet by 3G/HSPDA for long period like 1h or more) and under "normal" daily use (checking e-mail regularly, 20 min phone calls, sending some SMS, 30 mins internet, 45 mins playing around / listening some music) around 1.5 days.
My settings are:
3G/HSDPA enabled
Weather update every 6 hours
Stock auto updates - every 8 hours
Bluetooth and Wifi off unless needed
Screen brightness - auto
Haptic feeback, Vibration - off
E-mail check: every 2 hours (POP3)
Faulty batteries? I think not....
Whilst I'm a master of google searching, I get worse results using the search facility on this forum than just using intuition.
Anyway, I just wanted to add my comments on battery life after owning a stock 1.43 phone from Vodafone UK. I was getting less than 8 hours life with everything on auto and making just a couple of shortish phone calls and a couple of quick browses. The rest of the time I was in standby and I thought that my phone was one of the worst out there. I had also installed Skype which I had running in the background which sometimes causes the phone not to go into auto-standby even though it would dim normally. I also noticed that I was in a very weak signal area and that my phone was constantly switching between 2G/3G/H which I understand can consume a lot of power. Also, I had stopped using wi-fi to see if that helped.
After reading a million threads, I decided to conduct an experiment last night. Usually if I charge the phone before going to sleep for 8 hours it is down to 70% when I wake up having been left in standby. So last night I disabled everything. Turned off 3G, data connections, My Location, Weather update, Stocks Update, FaceBook login, e-mail updates, Skype, bluetooth, wifi. In fact absolutely everything I could find that could be turned off except the basic 2G phone itself.
Guess what, I wake up 8 hours later... 96%.
16 hours later.... 81% with very light use.
Now I'm going to have to spend many days playing around with different settings to see which apps or functions are gobbling the power. I have a nasty feeling that the weak signal is half the problem
So cheer up! It's not ideal, but this is a brand new, smartfone with bugs - not a Nokia 6110. Higher capacity batteries and ROM updates will come. In the meantime you just have to figure out what is sucking up the juice on your HD2 and disable these functions if you don't need them or when you are not using them.
Good luck and enjoy it! The coolest phone around...

Hello everyone,
like the majority of the owners of HD2, in order to optimise the duration of accumulator charge, I use Band connection control programs , to pass in 3G only when it is necessary. Thus, I have:
- phoneAlarm: to force the 2G mode the night, and also for differ quiet mode if I am in meeting, etc…. In particular, in the case which interests me there, I force the 2G the night and asks to pass to 2G the morning.
- WMlonglife (version for HD2): which normally loads himself to make the effective switch 2G towards 3G or 3G+ if an application program requiring it is launched, and otherwise to remain in 2G. It should be noted that WMlonglife has two applis, one for the configuration, and to make manually changes 2G 3G, WMbandswitch.
- recently, I tested Bandswitch v2.8
I meet the following phenomena, and I would like to know if others also have them, and/or if there are parameters to change so that it goes better.
Point A: Already some question about the icons of the bar of state in top.
There are always two icons side by side. Tell me if I interpret them well.
one with a letter: G= GSM, E= Edge, 3G = 3G, H = 3G+
This letter tellsonly that this kind of network is available, but it does not say that one is actually connected there. Is it well that?
To know in which mode one is actually connected, it is another icon, on its line, with the 1 to 4 bars of reception and a small letter, which should be looked at.
This small letter, it is “H " ==> connected in 3G+, “3G” ==> connected in 3G, “E” ==> connected in Edge
and finally a simple antenna, which I imagine wants to say that one is just connected in 2G, no data connection
Is what all that is correct?
Is there another mean of knowing in real-time the current mode of connexion (and thus mode of conso of the accumulator)?
Point B, use of Phonealarm:
like said in introduction, I force the 2G (mode GSM/GPRS) during the night, and to 6:00 of the morning, I pass it in mode “house” where I put “Car”, by also putting the pin number at it, because it seems that for this transition, one needs the pin number (is it the radio cycle on-off?)
There, the first thing, they is that every morning, when I unlock it I find myself with the screen for input of the pin number, where it is enough to make cancel (because the code already entered via PA and even already connected). Moreover, if one tries to enter a pin number, then he refuses the input.
on the other hand, at this time, the telephone seems to remain in Edge icon “E”, and does not pass in H. On the other hand, so there I reset, then he will connect to H with the boot
Have you also this history of pin number?
For hangs, it is as if WMlonglife did not take the hand to force a 3G mode or 3G+….
this brings me to the point C
Point C: WMbandswitch… after a software reset, my Tel. is connected automatically towards the 3G network (or 3G+) of orange. On the other hand the morning (after to automatic wake up through PA), it remains in E. When I test action manually a passage in 3G with WMbandswitch, it does not change anything. I tested with radio operator chip on Samsung, or Qualcomm (WCDMA). similar behavior….
To check out, I then loaded and installed Bandswitch 2.8, and tried to change into 3G, and there I see appearing the letter H. so, there is a difference with WMlonglife, which would seem to show that WMlonglife does not manage to make the switch towards 3G.
Which radio chip put in WMlonglife?
Have you to it even thing?
Poind D: use of bandswitch 2.8 (on xda): I tested. Hard to know if that is interfaced well with all the remainder. Of your experiment, which one would you advise? It does not have the system of “whitelist” like WMlonglife…
Here is, in synthesis, to summarise my questions
- Has: major significance of the icons
- B: phonealarm and switch of the 3G mode (after a forcing in 2G the night)
- C: WMbandswitch, and configuration/use for HD2
- D: alternative to WMlonglife?
For info, with normal use of browsing, email and phone, I drop of about 50% battery for 24h, that is not so bad, but I 'd like to make sure about the Bandswitch thing...
Thank you in advance for all…

Help? A few uncommon problems

Ok so I received my Vibrant on Monday and so far I am in love with it. Their are three things that bug me, however.
1. Battery Life is TERRIBLE. I know, I know-This has been discussed before but I did everything the other threads said and still no difference. On my phone, I will leave it on standby and it will drop 8 percent in like an hour and a half. Somethings wrong. Also, If I play the Sims for two hours (like I did today) my battery goes from 98% down to 45%. Is this normal?
Just to point out what I have going on with my phone:
- Brightness is turned down COMPLETELY. Automatic brightness is turned OFF.
- 3G is always on. Could this be the culprit?
- I have a completely black background.
- Last I checked, it said my display was taking up 60-70% of my battery usage.
- As stated above, Sims DRAINS my battery. Either somethings up with my phone or Samsung should have made sure the Sims doesnt kill the device.
2. The second I take my phone off the charger, the battery goes from 100% to 98%. Can I fix this? Its kind of annoying...
3. Problem with the Sims. Im not sure if any of you have this issue, but whenever I tell my Sim to watch TV, the app shuts down and takes me back to my home screen. Any idea why its happening?

1. Leaving a phone in 3G all the time is not a good idea, if you have WiFi near you you can connect to I'd use WiFi instead, it has less battery drain then the antenna that is constantly searching for 3G signal - unless you are in the area with bulletproof 3G coverage of course.
2. It seems like this bug is common 100% jumps to 98% once you unplug the charger, are there really any accurate battery meters on the market?
3. Can't help you there, not playing the game on my phone.

alright thanks. im in phoenix here so i am almost always in a 3G area. I guess i'll leave it on since i rarely dont have 3G
I also read on multiple forums including HoFo that 3G generally consumes more energy then WiFi.
sims 3 fix
so my girlfriend was complaining about sims crashing when she watched tv or relaxed on the couch. i fixed this by moving both the sims launcher app and the sims game app to data/app.
I normally use Edge simply because I don't need Wifi or 3G on unless I'm doing some heavy data transferring.
Currently I'm at 61% battery, which means my phone has been off the charger for 16hours. Its not a fluke either because its just normal use for me. I normally take my phone off the charger at 6am and I plug it back in around 11pm.
Prolonged GPS, Wifi and 3G will eat your battery. I'm not saying don't use the services, but you give up one for the other. I personally like to have awesome battery usage until I'm out and about and really need to use my phone.
I'd recommend you call T-Mobile customer service and have them diagnose the problems you are having and issue a replacement if necessary.
Based on my experience, battery life is excellent, probably the best I've seen in any smartphone in this category. Battery usually last easily through the day with heavy use, including:
- having 3G on all the time (and frequently switching to edge and back)
- 2 email accounts using push (gmail and exchange)
- gps on all the time
- google latitude running all the time
- facebook and twitter sync'ing every hour
- fancy widget sync'ing every two hours
- Newsroom harvesting 12 news sites in the background
- occasional picture (3 or 4) a day
- web browsing and searching
- xda app for reading and replying to this forum.
- bluetooth is always on
- wifi is on from 8 pm on.
I charge the phone through the night, unplug it at 8 am, return home at 8 pm and put it to charge around 11 pm, with still 50%. Brightness is set to auto. Phone is not rooted or modified in any way.
You bought a high end phone that should perform as such. You are supposed to get the most out of your phone, not turn off its features. I wouldn't listen to those who claim you should turn off everything and dim the screen. What's next, not using the phone to preserve batteries?
That's just my two cents.
Sent from my SGH-T959 using XDA App

Phone uses 50% in standby for 11 hours

I leave my phone in the car while I'm in the police academy and that's from 1000-2100, so it's about 11 hours. I might go check emails during lunch for about 10 mins but that's it.
by the end of the 11 hours, the battery is at about 50-60%
is that normal?
oh, tested it with noLED app, the battery was at 28%, so it uses about 20-30 more battery
Info that would be nice to have so others can help... Are you running a completely stock rom and kernel? What kind of signal strength do you get there? What is your TWS? Do you perform the 'Airplane Mode' fix on each boot? Do you kill the DRM service each boot? It would also help to have details like what rom and kernel you are running if not stock.
My best battery life that I can recall occured when running the Epic Experience Rom 1.1.06 and the Andromeda 1.4.0 kernel. When at home with WiFi on, 0% TWS (solid signal from the tower), I would lose about 1-2% per hour with no use, and I can recall having it last for almost 2 full days with light usage.
Another question, if your leaving it in your car anyway, why dont you just turn it off? Then it wont use any of your battery.
Anyway, in my limited experience, 5% per hour on a completely stock phone is about normal, and the only way I was able to increase it even a little was to install Juice Defender and have it kill any data access when the screen was off. This was before I rooted my phone, and learned anything about the 'Airplane Mode' fix (hold power button and turn on Airplane mode for about 10 seconds, then turn it back off. This reduces your TWS (TimeWithoutSignal) percentage) and killing the DRM service through the 'Settings->Applications->Running Services'
I lose under a percent an hour when the phone is sitting idle. Also, if I had to leave the phone for 11 hours, I would put it into airplane mode, or rather have juicedefender do it automatically. That would mean I would be losing under a half percent an hour.
That sounds about right from my perspective. Everyone that complains about the Epic having terrible battery life doesn't know how to manage their phone settings.
Personally, I use my phone often at work (ie., games, texts, and emails) and after 12.5 hours my phone probably has 60%-75% battery left. I do this by placing my phone in airplane mode and turning on my wifi. Using Google Voice and my gmail app I get all the information I want / need. On top of that I play games and surf the internet on my phone.
Anyway, I find your results typical from my experiences.

Best way to increase battery life...

This isn't a thread for when your battery drain is excessive on standby, this is a thread dedicated to figuring out how to simply get more power to the phone for extended runtime.
I'm using a 5000 mah external battery pack for extra charge, and it seems to be good enough to last me at least an extra day or two of usage, which is great. It seems like the only other options are cutting up the battery door to fit an extended battery from the evo 3D or just carrying extra batteries...
Best easy change for me was always using wifi instead of the network when at home and work. Made a huge improvement

So....how to get the most time out of your battery in standby?
As you've allready said:
One of the biggest improvements is possible by using a Sensation or Evo3D battery. With that i get a nice 1% per hour in standby. (It's actually a bit lower than 1%).
While not using the phone it's unnessecary to have 3G activated. Recieving emails and texts via whatsapp, viber etc via 2G is good enough. For everything that is more datahungry you can allways activate 3G manually.
Keep background data turned off. I use K9 Mail which works independently and Whatsapp recieves messages too. But a lot of other stuff doesn't syncronize which means less wakelocks and thus less power consumption.
Same with locations. As long as you don't WANT to tell google your every step you can keep network based location turned off.
If you need a location fix quickly you can allways turn on gps for a moment. After using the FasterFix app (i guess you need root for that), i get a gps lock in 5 seconds, so i can determin my location really fast and share it with others (for intance via whatsapp) without having to keep it on all the time.
And last but not least:
You probably don't need to know the current outside temperature every 5 minutes. So set that to manual update too.
Doing these things doesn't turn my smartphone into an overweight dumbphone with a battery problem and i get a maximum of over 4 days of standby time out of it.
Normally my battery holds for roughly 35 hours (1 day and 11 hours), but it's usually awake for 1/4th of the time serving as my newspaper and video and mp3 player.
/edit:
Totally forgot:
Use llama!
You'll never have to worry about forgetting to set your phone on vibrate while at work and setting it to loud at home.
You can configure it so it only activates wifi at home and turns it off again if you didn't connect to any access point after a set amount of time. I haven't had to activate/deactivate wifi manually for ages without having to worry about it constantly searching for networks and sucking my battery dry!

Exactly what he said, but you can automate a lot of it by using an app called Tasker. I use it to sync all data on my phone for 3 minutes every 4 hours so it's always up to date. It can also automate the GPS on/off depending which app I use so it switches on when I open CoPilot and turns off again when I close it.
Tasker can also replace Llama if you can find 'profiles. to do it. Llama looks pretty good though.
I think the biggest drain is the display. With auto brightness on, the sensor will monitor the changes in your surrounding every second the moment you turn on the screen. Turn that off and manually control the brightness save a lot of battery.
Or just use lower autobrightness script.
I use Invisibright. Long hold on search softkey + slide enables me to set the brightness to whatever I want in a second no matter what apps are running.

It is still useless as your sensor is still working every time you turn on your screen. The sensor is draining your battery. Not the brightness value.
Autobrightness sensor drain
So you think that there is a greater drain from the light sensor than from an uncontrolled screen brightness?
Interesting thought. I'll manually set my brightness level a round20% for the next charge cycle and see what effect it has, though I suspect that as my display currently accounts for 20% of battery drain it won't make all that much difference.
I use juice defender and I think its actually working.
