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…

I've been seeing a lot of posts on crap battery life around here, and I was chasing my tail about some of them as well, following a lot of misinformation even by senior members. I think I have a good handle on it now, and picked up most of these tips from these forums, so I'm not taking credit for these ideas, just collecting them in one place. Some of my suggestions assume you have root and Rom Manager (see the Tips and Tricks sticky thread on how to get them).
1. If your battery drains in less than a day on standby, you probably have a bad flash of the JI6 modem (either from the OTA update or from a ROM). Flash the JI2 modem from here "www dot teamwhiskey dot com/home/downloads". If the flash fixes it, you may try going back to JI6 if you want, and it may stay fixed. I went back to JI2 and didn't bother going back to JI6, but it has worked for others. With JI2 and 3G on I get just over 24 hours in normal usage.
2. The #2 battery drain on standby is 3G. I turned it off (Settings/Wireless/Mobile networks/Network mode/GSM only) and my phone lasted for 40 hours on Edge with light usage (few phone calls, messaging, quite a lot of web surfing, 2 hours of podcasts). Didn't even feel too slow (I get 140kbps on edge). Can anybody suggest a really good widget for turning 3G on/off? I use the 2G-3G OnOff widget by Curvefish. It's not one-click, it's just a shortcut to Mobile Network Settings, but it works. Note that sometimes it takes a while for the data connection to re-establish after you see the 3G or E icon.
2.5. WiFi always on is a huge battery saver! It keeps 3g off. I can easily get 3+ days with light usage on my home wifi. Settings/Wireless and Network/Wifi Settings/Menu/Advanced/Wifi Sleep Policy/Never.
3. Don't need a task killer. I wasted all my time killing tasks trying to chase down my crappy battery usage, but since I fixed my modem and turned off 3G I know that the 3-5% CPU usage at idle does not hurt my battery. Taskiller for me was actually hitting the CPU constantly, lightly but for no reason, so I got pissed and uninstalled it.
4. Install a CPU usage monitor like Usage Timelines. It sits in the notification bar, very easy on the battery, but tells you if you have a rogue app pegging your CPU and draining your battery. These are the only apps you should be worried about killing. Astro File Manager has a task manager that shows CPU usage for each app, so you can kill the rogue one. I shoot for about 5% cpu usage at idle (at 200mhz - at 100mhz it would be a bit higher).
5. The app Autostarts lets you disable any app from starting on boot or other events like connectivity changes. This is not strictly necessary unless you have a lot of crap apps installed on your phone and they like to start themselves and waste CPU time behind your back.
6. If your battery reads less than 100% as soon as you unplug it from the charger fully charged, or your battery meter sits at 100% for a long time after you unplug it, you can recalibrate your battery meter. To recalibrate: 1) charge your battery to full, 2) unplug, 3) reboot into Clockwork Recovery and 4) Wipe battery stats.
7. There is No Such Thing as "battery reconditioning" (for all intents and purposes). The above procedure only RECALIBRATES you battery METER to read on a more linear scale between full and empty. It DOES NOT make your battery last longer, period. Whoever tells you that is a moron. If your battery is dying in 6 hours, doing any amount of calibration will not make it last longer (I've tried).
8. I wouldn't be too worried about undervolting, overclocking, kernel tricks and superawesomefast ROMS. The CPU drain at idle is so minuscule (as long as you don't have rogue apps) that those things make precious little difference. Like I said, the biggest drain is 3G and other radios. Having said that, I run Bionix 1.9 with the JAC kernel. It drained my battery in half a day at idle until I flashed the JI2 modem. With JI2 it suddenly started lasting over 24 hours, and once I turned off 3G, over 40 hours. I like this ROM and see no need to switch, it's very smooth. But you should be able to get similar battery life on a stock Vibrant.
9. I have GPS on, WiFi never sleep, auto-brightness, and a few widgets on like Weather and friend updates. I have no fancy settings, literally just turning off 3G (or wifi on, which is the same) got me 2-3 days. So I wouldn't waste time fooling around with magic settings (other than wifi never sleep), battery saver apps, etc.
10. If your screen is on all the time and you're playing games nonstop, you're draining your battery quicker than any of the things I mentioned above, so you probably don't care. In that case an optimized ROM/kernel is probably your best bet, especially JIT in Froyo. You can probably save on screen brightness as well.
If you guys have any other tips I'd be glad to add them to the list, but I hope this gives you an understanding of where your battery life is going. Basically: bad modem, 3G, or rogue apps.
Also, I hope this will put an end to trolls calling people whiners for complaining about battery life and saying unproductive **** like "you're a whiner" or "the Galaxy S is just a battery hog, live with it". It's not, you don't have to live with it, nobody should have to, here are your solutions.
Good luck.
A few things I do to help with battery life is:
Disable Audible touch tones
Disable Audible selection
Disable Haptic feedback
Disable SD card notifications
Set animations to NO animations
Uninstall media hub if you dont use it
Disable auto brightness adjustment
Disable power saving mode
I disable the last 2 and just swipe the notification bar to adjust brightness. Granted these items really only work when using the phone but I can go about 2 days of normal use without a charge believe it or not.
yeah disabling 3g has always been the best option for people really, really concerned with battery life.
But it's kinda hard to tell people not to use 3g on their brand new 3g capable devices.
You may want to add how to test if you battery is bad. If you use you phone repeatedly while it its plugged in you risk overheating and damaging your battery. Signs that unitas is the case are very quick drain and long (7 hours) charge times. You can easily test and see if your battery its damaged. Remove it from your phone and place on flat surface (e.g. Counter top) try spinning the battery. If it rotates easily and quickly you battery is bulging, this is a sign of damage. Time for a new battery.

Thanks to the OP and other contributors in this thread.
I flashed a ROM with the ji6 modem and battery life has been noticeably ****ty since. Example - this morning I unplugged my phone at 7:30 am. 100% charged. It's 10:21 am and my phone is at 75%
In the last 3 hours I browsed the web for 10 minutes while having my coffee and a smoke before heading out to work. Blue tooth was on for my drive, and I've sent 2 text messages. Aside from that my phone has been on stand-by since I unplugged it 3 hours ago.
I'm going to try to flash back to ji2 tonight as the battery usage was definitely better. Will also look into the 3G thing.
Thanks again.
You forgot to mention the two DRM and one downloader services that run resident on JI6.
These were the cause of my reduced battery life after I upgraded. Killing & removing these processes restored my battery life back to normal

I just tried this - switching 3G off works fine, but switching 3G back on didn't work for me. I had to re-boot to get 3G back so this is a no-go in my case.
I know how to kill the processes for the DRM and downloader but how do I remove them?
OP thank you for putting together the list. But I've never seen the point of doing all this. Its like getting a lamborghini and only driving 40mph because it you don't want to waste gas, whats the point? Either get a second wall charger to charge at work or a car charger. Heck even get a second battery if you are out for a long period of time.

You don't need to disable 3g.
The point of my post is to avoid people wasting their time with tweaks that have little to no effect on battery life. I'm telling people that they're wasting time killing apps and optimizing cpu usage and twiddling their settings when the radio drains most of their battery on standby anyway.
Meaning no matter what changes you make, you can only hope to improve your battery life by a tiny amount, because any other effect is overshadowed by 3G.
Put another way, you will NEVER get battery life much longer than a day if you're on 3g, so you're wasting your energy trying all kinds of tricks.

For me the widget did nothing. But it seems like it's not even supposed to turn the 3G radio off, but ALL APN network traffic. Did I miss something? It won't save battery power as long as the 3G radio is on.
I went back to the 2G-3G OnOff widget by Curvefish. It's not one-click, it's just a shortcut to Mobile Network Settings, but it works. Note that sometimes it takes a while for the data connection to re-establish after you see the 3G or E icon.

While i understand the idea behind this thread, your conclusion is simple.
If you use the phone as a smartphone, it will eat up your battery no matter what.
I personally go through two batteries and some a day. (they cost about 12 bucks in ebay, and they work just fine)
The price for saving battery is not using the phone, and having a 400 bucks phone just for show off is just silly at least.
If you have a phone like this is to use it. At least you can change the battery not like some other devices......
I understand that task killer is useless, but do any of you use Autokiller (memory manager) ?
That's kind of a redundant question because even if you do not use the app, your phone is still performing the functions. The app just adjusts the settings. But to answer your question, using a memory optimization tool such as AutoKiller is 1000% more efficient than using a Task Killer. I don't think it effects battery much, but works wonders on performance.
There's no 3g-off widget because apparently in Android there's no way to do that through a direct command. I also use the Curvefish widget, and you are absolutely right about turning off 3g to save battery. I normally do so when I'm asleep or if I'm sitting at my desk next to a computer (why do I need fast data on my phone when I have my computer right here?).
The other thing I would recommend is AutoStarts. There are way too many apps that open themselves up at bizarre and inappropriate times. Autostarts is an easy and painless way to see which apps do this and keep them from opening.

Great battery life comes to people who hardly use their phones. Guess I need to get a netbook. Will prolly get a netbook or 3g laptop + skype and ETF my phone soon. These battery woes are show-stopping.

Losing 4% an hour on standby when you're not using the phone is unacceptable. Samsung screwed something up with the JI6 update. Most people think it's because of the stupid Media Hub. I think they are right.
People are not complaining about the poor battery life from using the phone. They are complaining about the slow battery drain even when they are not using it. ~4% an hour adds up fast. Vibrant is supposed to have 450 hour (18 days) stand-by time. That's what is rated. But people are getting 24 hour (1 day) stand-by time after JI6.

I'm not ready to sign off on this idea. For me simply flashing JI2 over JI6 fixed it. For some people flashing JI6 back over still left the problem fixed. I still have those processes running on JI2 and my battery life is fine.
The other reason I'm not ready to recommend wiping out those DRM processes is that apparently it stops the bundled Avatar movie from playing, and might affect other things that users may get pissed about. I've read that killing the downloader process people are talking about kills the market. So I really wish those people advocating that solution would figure their **** out and provide exact steps for the fix (right now their posts are really vague like "kill the processes that are named something like this" and not well tested; in all my research I didn't find the exact name of the "downloader" process).
Is it possible to flash the ji2 modem without root? Wishful thinking, I suppose..
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.

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.

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.

I'm using the premium one though so there is a few extra settings. It definitely works though.

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...

Original name is "Android assistant(12 features)", by Aaron, he done already few apps for improving battery life, very good app incl cache cleaner and few more extras.
Hey there, I really have on problem with my N4 since I own it:
From time to time my battery drain just goes huge. For me it feels like that is everytime I go out and have my phone in my jeans pocket. So at some point I thought I would press the button to active the display all the time.. but thats not happening (according to GSAM Battery Monitor).
I had all 4.2.x stock ROMS + stock Kernel and also with Franco Kernel. I always had this problem from time to time.
Signal is there, there is no significant battery drain from any app. The % of each app is normal and I also dont use any app more than usually. I don't have new apps.. everything is like always. Still my battery goes from 100% to 0% withint ~ 6 hours (30 mins SOT).
Any ideas? My battery is at 47-50 Celsius, the cores go offline as they are supposed to. I tried reboots in between e.g. in case an app is bugging. But actually all apps are as usual :/
Thanks
@edit: it also happens when the phone is on my table.. i just had it with 17% left on my table, didnt touch it.. after 30 mins it was off because the battery was empty. wtf ?
The biggest battery suckers are radios and the screen. I turn off wifi, GPS and BT whenever I'm not using them. Keep a short timeout for the screen.
Unfortunately, six hours doesn't sound too far off from normal if you've got things running. I'd go through an entire battery cycle watching a 2-hour 1080p movie. Overnight, my battery dropped about 15% while only bluetooth and GSM were on. The N4 isn't really known for good battery life :\
BT is off. In general my battery holds up one day without any problems. But sometimes it goes down within a few hours and I dont know why.
Possibly a scheduled background service? Maybe Google Sync is pushing a whole bunch of data periodically?

Hmm no not really. Also, it would happen every day or in some interval. Not just on random days?
besides that I dont use any syncing and also it would be shown in the GSAM Battery Monitor or general battery usage ?
I dare not say I'm a professional in battery saving, but I did break the 8 hour SOT on N4(minimum brightness of course).
Let's see, I only use 2G, because I only need internet for Whatsapp, and I greenify every single other apps.
You might undervolted too much according to your signature. -200mv might reduce heat but consume 1.2-1.5x more battery than normal voltage, its hard to explain, but its the truth, try -150 then -100.
Since you're on Franco, reduce the vibration a little, as for scheduler, I personally prefer Deadline on 2048. Governor definitely interactive, and freqs at 1.2Ghz. Because personally I dare-say at 1.2 Ghz you can run most apps almost instantly.
Like the second post said, Off wifi, GPS and bluetooth. Under settings > location settings> one is GPS and another is google location, off both. And you might still even have NFC on? No idea in this.
Download an app called build.prop editor or kernel tuner.
Modify build.prop a little. Add in pm.sleep_mode=1 and change the value of wifi.supplicant_scan_interval to 600 or 900.
Disable auto brightness and fix to something you like but below 50% .
I am not on -200 anymore.. -100 all the time
i also use greenify for nearly all my apps.
GPS, BT is turned off, Wifi normally too (tasker is doing that, depening on GSM antenna reachable or not).
The other tips are really nice but should affect the battery drain THAT much ?
Thanks !
As a little update:
It seems like this only happens at certain locations ?!
E.g. at work.. everything disabled (wifi, BT, gps, etc) .. even Tasker is disabled incase it was bugging -> about 10% for 30 minutes.
I have full connection bar to my carrier.. what the hell is that ? Battery temps are normal, same apps running as I had running when I was at home. I don't even use the phone but as soon as I get to work and my phone gets a carrier signal, the battery graph shows a rapid drop.
19:34 - 61%
20:03 - 54%
20:20 - 48%
20:54 - 38%
21:20 - 31%
Battery sitting at 37 Celsius... why.. why why ? :S
Alright now I know when my battery is crashing:
as soon as I turn off and I connect to my carrier. but why? Normally it should be exactly the other way. When WiFi is on and connect, the battery drain should become higher.
But as soon as I leave a WiFi, my phone gets hot and looses A LOT of battery very quickly.
Any ideas ? I have full signal.. but in any case.. I have the same signal as I also when while connected to Wifi.
e.g. at home with wifi - good battery life. but as soon as I turn the wifi off -> battery loss !
