Hi there,
I've been using DHD for more than 2 months, and I have problem (or feature, depends what month it is
Where I live we have air temperatures around 37°C right now.
When I normally use my DHD, it runs with battery temp at around 31°C, sometimes a bit more. But, If I put it on a windscreen inside my car, it overheats in few minutes reching more than 45°C which is overheting limit. All this means that I can't use my DHD for navigation, or for Blackboxing (DailyRoadrs Voyager, Autoguard).
I drive myy car daily for more than 200 kilometers, and I find my self in very odd situations daily, and if I have to prove my innocence having my drive filmed can help me a lot. Thats the reason I would like to use this blackboxing programs daily.
I was thinking to undervolt my DHD or set lower CPU freq.
Does any body have similar problem or maybe an answer.
Thank you for your reply.
Well if your dhd is in the direct sunlight inside your car it's normal that it's that hot and there is nothing you can do about that.
To lower the battery drain, and as a result the battery temperature, you can lower the screen brightness, or UC/UV your cpu. Those are the main factors of the battery drain.
Furthermore you can turn off the data connection while driving because it needs way more battery when you're driving

Apparently, the battery life and the low internal memory are some major drawbacks of this otherwise great handset, so I though of putting up some experiences of what users report from their experiences with internal memory and battery life.
(After installing all programs and under normal usage)
ROM:
System 260MB => 32MB free
Data: 150MB =>32.7 free
Strategy: rooted, uninstalled htc stuff.
Battery Life:
24-36 hours
Remarks:
I feel the battery behaves rather strange, think there is definitively room for improvement. Some days, it hardly uses 5% over 12 hours!! Then, on others, without touching it, it looses over 50%!!
I am currently playing around with the Network settings and will see what I find.
Underclocking on demand should further alleviate the problem I hope!
With the original WF I easily got 4-5 days and the battery is only marginally smaller so should be possible to get closer to this range
Here my results:
About 50 MB free of ROM.
About 100 MB free of RAM.
Stock ROM, S-ON (waiting for htc unlock and cyanogenmod)
Battery lasts under normal usage 2 days, light usage 3 days. (When i sleep phone is in fly mode and there's no battery drain)
Normal usage: little browsing, messaging, mailing, music listening, checking news and weather, maybe a phone call.
Light usage: messaging, mailing, a bit music listening, calendar checking, very very little browsing
The biggest battery drain is the screen, especially when playing games (15 minutes dragon fly gives 10 % battery drain) and browsing, market checking/updating.
Everything stock:
free ROM: 47
free RAM: 122
Around 2 days battery use if I don't play too much Airport Mania 2, or else 10 minutes play equals minus 5% battery
UPDATE:
I changed some settings to maximize battery performance, notable
Location => Disable "Use Wireless Networks" (battery eater!!)
Wifi&Networks: Mobile Network Settings:
Network Mode: GSM only (OK I don'T need the fast one)
Enable Always-On: DISABLED
Plus I set it on Flight Mode during night (I used Gentle Alarm to do it before, but apparently there is a bug where it makes it consume engergy nevertheless so do it manually now for the moment)
Results:
For now, 3-4 days!
Will continue trying out (but now it will take a week or two to finish some cycles ;-) )
RAM : 241 free / 160 used
ROM : 70 free / 80 used
Cyanogenmod 7 / 1500mAh HD7 battery
1,5-2 days with fully wifi opened.
Sure you can kill 3G, WiFi etc but then why have smartphone and dumb it down?
Here are a few battery saving tips I've learned from owning a GSM Hero and Desire HD (my gf has WFS which is why I'm lurking here... just ordered a XTC Clip for it).
Unfortunately when the green light says you're phone is fully charged this isn't always the case. The battery is likely to be mis-reporting its capacity and % used, this can cause your phone to die when the battery still has remaining charge. So, we're going to fix that.
Assuming you have already rooted your phone, download Battery Calibration tool and CurrentWidget.
Place a CurrentWidget widget on your home screen and charge your phone until the widget says 0mA. This means it has reached fully capacity.
Once it hits 0mA on the widget, open Battery Calibration and wipe battery stats.
Reboot your phone whilst still plugged in and upon reboot it will recreate a new battery stats file, however now it will know the battery's max capacity and will correctly report battery % used.
I do this about twice a week. Maybe once a month I will also let it completely die and then fully recharge whilst off, before powering on and repeating the above steps.
Other things you can do to increase battery life are:
Change the sync interval of apps like Facebook, Weather etc. I usually set most things to every 3 or 4 hours, with Flickr only being once a day.
Don't run the screen at full brightness if you don't need it. On my DHD I find 40% to be best for most conditions, with only really bright sun making it hard to read... in which case I bump it up to around 75%. Auto-brightness if ok but it tends to be on the bright side on most Sense ROMs so hopefully someone will work out a way to tweak the values for WFS. I had a play about with custom values on DHD but after testing for a while I still prefer to control it manually. It's a personal thing though.
Remove crap you don't need. Stocks, News, eReader, Twitter etc are always the first to go when I install a new ROM. I use Root Explorer to delete them but there are various ways to do this including Titanium Back-up or by using ADB. You can find everything in /data/app & /system/app. Just be sure to do a nandroid backup in case you delete any system critical apks.
Change Wifi sleep policy to Never.
Limit your homescreen widgets to only ones you really need. Having 7 screens packed with widgets and apps will cause battery drain.
Turn off Power Saving mode. I tend to find it doesn't really help and just makes your phone quite useless when you hit the pre-set % where it activates.
Never use Task Killers. This link gives an excellent explanation.
Finally, wait in hope for an overclocked and undervolted kernel, different radios and custom auto-brightness values
If I can think of anything else I'll post it here
don´t know why so mutch people get worried about the battery. for me the only thing that counts is that the battry takes me over the day. i mean i go out an seven am and get bat at 5pm, so thats the time i need my battery to hold. maybe i need some backup to get until 22 pm and everything is alright.
for me i doesnt matter if i´ve to recarge after one day
Yeah, for some people it can become a bit of an obsession. However, it still think it's worth taking a few simple steps to get the best out of your device
For some people 8 hours between charges is fine. For me, I like a phone that can run for 8 hours between charges, but also run for 48 hours between charges (without having to go to dead mode by turning on airplane). I go camping, stay the night someplace else, forget my charger while going on a trip or just want the freedom of not having to find an outlet and drag my charger with me if I want to have a phone run for more than 8 hours. So I get off work, change my clothing and run out the door to my after-work sporting event, then head out for a few beers afterwards with the team and I barely have enough juice left to call my wife or check on a few game scores.
It's important. Not having it be important means your phone is running your life or you just always have the same routine, which is fine for you maybe but I like to head out.
About 7 hours running CM 7. Battery life is very bad at the moment.

Quick Tips
NOTE: As with many devices in their early days, there seems to be a few bugs needing to be worked out. Some of which include:
High "Android OS" Battery % usage. Possible remedies include settings->Wifi->Advanced(menu)->Keep Wifi on ALWAYS when sleeping; Trying alternative kernels from the dev section; although 4.0.3 may have some improvements, early leaks are not yeilding substantial changes.
High "Media Server" battery % usage when using a media app with audio, video, etc.
High Preset voltage table in kernel can be fixed with UC Kernels, but proceed cautiously.
http://code.google.com/p/android/issues/detail?id=22878
Battery Capacities. NOTE: The batteries are NOT interchangeable between GSM and LTE!
GSM: 1750mah
LTE: 1850mah
LTE extended battery: 2100mah
GSM extended battery: 2000mah
Settings that use us battery:
Screen brightness: Using the lowest comfortable setting will save a good bit of battery, espescially on such a large screen. App LogGraph can be used to change auto-brightness levels
Haptic feedback: Switch this setting off (Settings->Sound->Vibrate on touch). You may need to turn this off in alternative keyboards. Vibrations on button press, unlock, etc will use power for the vibrating motor. This includes vibrating for a call or text.
Button Sounds: Switch this setting off (Settings->Sound->"Dial pad touch tones"; "Touch Sounds"; "Screen Lock Sounds"). Speakers are small electro-magnets and require energy to move, consuming a small amount of power.
Sync: The more frequently your apps sync the more energy will be consumed. Turn off unnecessary syncs and reduce excessive syncing (Settings->Accounts & Sync->...) Alternative apps such as Juice Defender and Tasker can be used to control sync settings. Some ROMs are now incorporating this feature as well.
Antennas: The short of it: Use Wifi as often as you can, it scans for a connection less often than mobile data. BT, and GPS antennas use very little power when idling. This is the most often confused aspect of battery life. Read more in the "Nitty Gritty" section.
Live wallpaper: Requires greater CPU usage to run, and currently ICS lags in this CPU processing, as demonstrated when switching an older phone over to ICS and finding lag in the wallpaper.
Widgets: Higher refresh rates, sync intervals and greater changes in the widgets will consume energy more rapidly.
AMOLED Screen consume less power when displaying black.
Auto Rotate uses greater CPU and changes screen.
Apps for reducing battery usage:
Juice Defender - Very easy interface for switching wifi/bt/3g/etc on and off to save battery. Great first start. WARNING: Some users report greater battery consumption when USING juice defender. This may be due to certain settings they have or the app itself.
Tasker -Much more advanced, and less user friendly application for automating processes on android. Can be used to closely control the behavior of your phone.

Battery Monitoring
Standard Android OS Battery Usage Utility
Settings -> Battery
When entering this section, you will see two distinct sections:
Battery % graph, which shows the amount of battery used since unplugged, as well as a time on battery.
Individual App/Process battery usage. The Percentage here corresponds to the amount of battery used by the App/Process of the already used battery. NOT the total battery capacity.
Clicking on a process or app will bring up more details on that process. Some definitions used are as follows:
CPU Total - Total CPU usage in time
CPU Foreground Total - Total CPU usage while app is visible to user
Keep Awake - Total time app prevented phone from going into “Deep Sleep”
Screen on Time - Time screen was active (duh...)
Time on - Time process has been running
Battery Monitor Widget
I highly recommend this app. It gives you a wealth of information.
Battery % usage over very long periods of time
Battery voltage recording
Battery drain (mah and watts)
Battery capacity estimates (both in time and mah)
Battery conditioning status
Support for multiple batteries
Estimates for various conditions (watching video, audio, games, etc)
CPU Spy
I use this for one purpose: to see how much time my phone spends in each CPU frequency. And more importantly, how much time it is in deep sleep. Deep Sleep is the condition in which the phone suspends as much activity as it can. This is the lowest consumption state your phone can be in... besides being off

The Nitty Gritty
The key here is to think back to physics class. We have an energy storage device, and a few devices that consume energy and varying rates (power - NRG/Time)
Kernel Stuff
Adjusting Clock Speed - CPU and GPU frequenxcies will directly effect energy consumption when in use. That is to say, if your phone is just idling with the screen on, the CPU is using very little power. Much more is being eaten by the screen. There are two approaches to saving power in clock speed, both of which aim to reduce the time spent at higher frequencies.:
Reducing maximum clock speed.
Using cpu governer that keep the CPU at lower frequencies for longer periods of time. Power save, conservative, smartass, etc take different theories as how to achieve the best ballance between performance and energy efficiency.
[TIP] Use CPU spy to check much time the CPU spends in each frequency, and more importantly in deep sleep.
Adjustiing CPU Voltages - Using a kernel with an unlocked voltage table and setcpu to specify voltages for each individual frequency can lead to significant power savings from the CPU. When experimenting with voltages, do not check “set at boot” until you have established stable voltages.
Suggested Voltage testing: Coming soon...
Antennas
Wifi
Consumes more energy per time when trasmitting than mobile data, BUT...
Takes less time to transmit data, espescially large files, so it consumes overall less energy.
Wifi scans for a connection and pings the router less often than mobile data, thus consuming less energy at idle
Bluetooth
Consumes a small amount of power at idle to connect to new devices
Scanning for deveices consumes more energy
While connected, very little energy is consumed unless data is transmitted.
GPS
Unless an application specifically invokes the GPS antenna, it will not consume power
Using constant GPS updates (as in Navigation apps) will consume a large amount of power
Some apps will have bugs in them which will keep GPS on indefinitely. Try reinstalling those applications first, then remove if necessary.
Mobile Data
2G antennas consume the LEAST amount of energy at idle, but because they take so long to trasmit data, they can kill your battery.
3G antennas are Ok at idle, but take less time to transmit data, so are the best all around for traveling around metropilitan areas.
4G Antennas are FAST, but consume the most power. Best to leave these off when in transit, and used for stationary, stable connections
All Antennas consume much more power idling in areas of bad reception. So if you know you're going somewhere with poor reception, and don't need data, turn it off until needed (Settings->Wireless&Networks ->More ->Mobile Networks-> "Data Enabled"; "Data Roming" OFF; "Use Only 2G Networks"
Radios
Radios control how your phone connects to the mobile network. Specifically which proticols to use in which regions as well as how often to try to reconnect. This can lead to better or worse battery, signal, and network speeds.

Frequently Asked Questions
Q: I just flashed a new rom or update, could that be the cause of battery issues?
A: Absolutely! A bad download, experimental features, or even settings that are not friendly with your device can greatly impact your battery life.
Q: What battery life should I expect out of my device?
A: That level can vary widely by usage. Generally, screen on time of 4+ hours is considered good.

Thanks, added that and tasker to the first post as apps that can help save battery
why many posts...
Hey instaed of reposting everything can you try putting all together in one post..???
I think this should be mentioned:
USE WIFI!!!
Using 3G uses about double the battery of wifi. Using 4G uses about triple the battery of wifi. If there is wifi near you, use it! Use wifi at work and at home if at all possible.

http://code.google.com/p/android/issues/detail?id=22878
For what its worth, my preliminary experiments seem to be showing that on the Galaxy Nexus, JuiceDefender uses more battery than it saves. FYI
is there any way to turn off the media server?
my battery is very inconsistent and at times I have horrendous drain
Not that it'll mean much, but Wi-Fi is the battery saver on this phone for me.
Light use all day, screen at 100% (which I turn off manually every time before putting it down)
E
verything on but bluetooth
Did some MP3 playback (2 hours), Lots of Tweetdeck, some maps - all while actually NOT on wifi (about 3 hours total) - the rest of the time I was at home.
I got about 18 hours before the phone shut off from a dead battery. The same without Wifi with 3G only would net me 8'ish. With 4G about 6ish - all with screen set to Auto.
So my casual and un-scienitific observation for my phone shows that there is something to be said about using WiFI instead of cellular service. I'll try and narrow it down further this week since I'm on vacation.

I had the same experience, but I like Tasker for finer grain control anyway. The main thing to be weary of is Location-based settings. Tasker has a guide called "Location Without Tears" to explain it.

Thank you for the perspective. I've added some sections referencing these issues.
I've been really surprised with the reviews about the battery life. So far I got the phone for a month ( in UK) and battery life is pretty good.
I have sync accounts, use the phone moderately (about 3 to 4 hours with screen on per day), no battery saving app or anything.
My daily routine is to unplug my phone from it's charger a 7am and every day I end up at night around 11pm with a battery around 40%... Some day I will forgot to plug it at night and be able to have it last almost for the entire next day (being careful though)
first week wasn't so good but after a few days battery improved significantly.
to me the key to save tons of battery life was to set the screen brightness to the second lowest level. It's really bright enough to my taste and literally since then I never got the phone to drain off within 20 hours after a full charge.
Also I have the wifi always on as mentioned earlier on the thread.
I have the GSM Nexus. I have had the phone for 1 week. My phone for phone calls, which drains the battery pretty quickly has not been real heavy as of late, but I have been typically seeing a 3% drop per hour of use. So right now I am at 78%, and have been up for 6h 48m.
Overall I am very happy with my battery life.

Click to expand...

Is this really a good idea? Consider the following:
Higher clock speed means getting things done quicker. If the phone is running at 1400MHz with a voltage of 1225mV for one second, instead of running two seconds at 700MHz with a voltage of 900mV, what will demand the most energy?
(Voltages are the ones I'm using on my OC/UV'd Nexus, not the stock ones which are *way* high)
I'd rather focus on lowering the CPU voltage as low as it goes without instability than waste time with a slow phone
If i use my GNex normal i charge every two days, i like maximum display
I noticed my battery life is terrible. My phone is only like 5 weeks old. I've tried the battery saver apps, power-saving, and pretty much every other tip. I start off with 100% in the morning with brightness turned down and everything else and I mainly listen to music more than anything so the screen is usually turned off. It still manages to go from 100% at 7:30 to about 17% at about 4:30. And the phone is turned off for about 3 of those hours. Also the other day I started playing TDKRw/100% battery life at 7:30 on high brightness and power saving was off. At 10:00 the battery life was at 15% not to mention I paused the game a lot. Is this normal at all?
Seems ODD. My phone is like that as well but one thing that i noticed is turning off cellphone data. that helps battery life big time. try that and see how it goes.
The TDKR, would be normal, the high end games just gobble up power, often even consuming more power then a charger can keep up with.

I was like that when I bought my phone, but after playing around with some ROMs and kernels, I found what's working for me - ParanoidAndroid + Ktoonsez kernel = 2 days moderate use and over 5 hours screen time with 100mV undervolt
OP might have bad reception too, that'll eat your battery up
Reception is a killer battery eater.
Especially for me, just moderate texting and some short phone calls will drain my battery.
It's because where I live, the signals are fairly weak and I will get EDGE or 3G data most of the time.
Additionally, check your wakelocks. Sometimes applications run during when the phone is supposed to be asleep. Getting a handy battery measuring app will help.
Also try turning off sync or turning your settings for e-mail, google services, etc. to manual so they won't run when you're not using the device.
Otherwise, the forums probably have dozens of posts with tips on increasing your battery life.
There are many battery threads, true. But as of a day or two ago, you only need one!
Woodrube ported his thread over for us. I highly recommend evrryone take a few min to read it!
http://forum.xda-developers.com/showthread.php?t=1969741
For those of you with poor signal and wind up on Edge, turn on wifi if possible. It uses less power than your data connection, plus, by having it on it disables mobile data leaving only the voice connection which is much easier to get a strong signal for. So in every way this could help with battery savings.
Even if you have a great signal, your wifi will still use less power. I always connect to eofi when I'm able and the sleep policy is set to always stay connected. If you set it to disable while asleep it simply will activate mobile data in its place.

Sorry for the slow response. Haven't had time to get on here. Thanks for all the help though. I was mainly scared though because I heard some of the phones had a bug in them to where it drains the battery life like crazy. I think that woodrube thread will help me tremendously.

The only thing about that is, I barely make phone calls or text at all. Like I might text 3 times day and make calls like 3 times a week.
Does anyone have any tips on listening to music. I use PowerAmp and I probably use my phone mostly for music.

Hi everyone, I have a bit of a heat problem with my Note II.
I noticed that, whenever I play a resource-intensive game (like Need for Speed: Most Wanted) while my phone is plugged, the phone gets quite hot. Eventually, this will lead to the phone becoming more choppy, even after I've exited the game (like when I'm just browsing my homescreens) until a time when the heat dies and the phone reverts to its normal, snappy self. It sort of reminds me of GPU throttling on PCs whenever I play a very resource-hungry game and the GPU temps go to, like 90 C. I usually just get rid of the GPU overclock and tone down the game's visual settings. Anyway...
I never experience this when my phone is unplugged. Games play smoothly and the phone just becomes warm, not hot.
I find this very annoying and scary at the same time. Is anyone else experiencing this? Any way to get around it? Maybe I should just leave my phone alone while charging, as I usually do...
Thanks for reading.
normal..
Atleast u play games... mine just by sitting idle gets hot/warm when charging...
