Battery Life

I have a widget that shows me how much I have left and when I unplug it after a full charge, I have 6 hours left.
Ridiculous.
This is on auto brightness, wifi, twitter/facebook/mail updating every 15 minutes.
whenever I take my phone out the house I have to bring a charger...
bloody ridiculous.

couple of points.
1) When you leave the house, don't leave your wi-fi on! I find wi-fi to be the biggest battery drain out of everything ( expect gps)
2) I use a brightness widget, therefore when your in doors you can have it on low, then when your out doors have it on high, i assume this will use less battery then auto brightness
3) why do you need facebook updating every 15 minutes?? Do you honestly look at your phone that much when your out? change the settings so it updates every 15 when your on wi-fi at home, and every hour for when your not.

Wifi isn't an issue. I leave it on 24/7 as well as bluetooth and still can get 36 hours out od a charge. Its hooked up to wifi 20hrs a day as well.

1. Battery and other constantly updating widgets are one of the causes for battery drain. Get rid of it.
2. Battery widgets try to get an estimate of your typical use. They are mostly wrong in my opinion
3. I can get 6 hours of battery, yes, but only if glue the phone to my hand and use it constantly for that time
4. there are tons of battery threads around, use those suggestions (mid brightness, no live wallpaper, turn airplane on when you know coverage will be unavailable for long, etc)
5. Battery gets better in 10 days.
6. Most people can get at the very least one day of heavy usage. If you really need to hammer the battery get a spare one, they are cheap. Oh, and realize you are lucky because you CAN have a spare battery !
7. If you are using an automatic task killer, get rid of it.

1) go to the market and search brightness level, or brightness widget, there are a number of these. The best i find is brightness level by curvefish, it lets you pick a percentage and keep at that .
2) Cant remeber actually where the settings are but there is a way. But i prefer to use another widget, autosync on/off, this allows you to update every 15 when on wi-fi, but when you want to save battery, turn auto sync off and it doesnt sync ,

I suggest you use switchpro widget. its like the power control widget but with more options to turn on/off things.

I typically charged my Nokia N97 every other day or so, even though I used it frequently, and needless to say the HTC Desire doesn't have the same stamina. I was quite frustrated by it, and I started thinking of ways to save power. I came up with 19 tips, and I have actually noticed quite a difference by following them
19 Tips to Keep the HTC Desire Running a Little Longer

Nice post thanks.ill give this a go. But I have a question to do with the positioning using data or gps. I believe your stating that you should turn data off for this purpose, and let the gps do it? however my phone was set to opposite. when I changed as you were suggesting and I clicked allow gps, I had a message come up saying to turn off to conserve battery? But your saying to turn on? And have data off? Also how do you get into htc facebook settings,i cant even find it!

yep i also use this widget
also use a free juice defender or paid ultimate juice that keeps turning on and off your 3g every now and then depending on how you schedule it, my phone with snowstorm weather widget updating every 80 minutes + 30s of 3g every 5 minutes to update mail etc and average usage lasts about 36 hours which is good enough for me

I leave my WI-FI on at home and suffer hardly any drain.
At work like today leave my Mobile network on down to 47% with just twitter usage!
Pathetic is the mobile signals drain.

Ok, ive had another read of this and am now just even more confused! Are you saying to have gps turned off via settings and location aswell as data, or just having gps on? Are you saying that having gps selected via settings for the purpose of locating services uses les batty than via using data? Either way, it appeatss that the power control widget controls the gps the same as via settings. Right now ive deselected gps and the data location.

I believe this is what I'm saying:
"To let your device learn your location via wireless network triangulation requires less battery than by using the GPS for this purpose. However, using both methods simultaneously is probably not a good idea from a battery point of view. The GPS can handle this task by itself, although it will get a fix on your location a little bit slower. Also, wireless network positioning will be used to collect anonymous Google location data, which will drain the battery further. You can change this option from Settings > Location > Use wireless networks. "
In other words, to only use wireless network positioning will supposedly use less battery than by only using the GPS, but using both methods will naturally use the most juice

For me...
- Turn GPS On when I needed.
- Turn WiFi On when I needed
- Turn Bluetooth On when I needed
- Use 2G Network for standard internet, we use 3G if we want more speed such us watch video

I can get get good days heavy usage (except games) from mine, I haven't tried the 2G thing yet.
Apparently it is the connectivity thing that kills the battery, but turning off 3G, doesn't that take all the fun out of it???
If you just use it as a phone then I reckon you can get a couple of days out of it, or so I've read...

How to turn gps on automatically when opening navigation?

As for those who don't know. There is an app out there called tasker. It allows you to program all kinds of tasks and conditions.
I used it in froyo to turn on my gps automatically when I opened the navigation app. However in gingerbread tasker no longer works. I'm reading that in cyanogen gingerbread roms tasker can still enable and disable gps.
Does anyone know anything about modding EI22 so that tasker will work with gingerbread on our epics the way it does in the cyanogen gingerbread roms?
Is there a patch or a piece of code that can be taken from the cyanogen rom to allow this on different roms/kernels?
Possibly is there an alternative to using tasker to get the gps to turn on automatically when navigation/maps is opened?

Just leave GPS enabled at all times. GPS won't activate until a program needs it, and won't consume battery life while it's sleeping.

Cool. I kinda thought that, but I wasn't sure. I guess ill need to turn off location settings for all the apps I don't won't to access gps. I appreciate the info. Thank you.

To go with this, if the GPS icon is on the toolbar (generally a bullseye/crosshair looking icon), you're using GPS and therefore extra battery--on the flipside, if the GPS icon is gone from the toolbar, then GPS is in standby and not consuming battery.*
* I'm not entirely certain that it consumes no battery when in standby, but it's certainly much less than when it's active. As long as you keep an eye on which apps you allow to use it and when, the battery drain is negligible--At least until you use Navigation and forget to plug it in! Then you'll damn near be able to watch the battery icon visibly tick down, and might could cook an egg on the back of your phone, it gets pretty hot!

If you running ei22 stock, I can leave gps on all the time and don't need to worry about battery. But if you put in the gps fix, careful.

Not your typical GPS question

I've noticed that after flashing a new ROM it can take the gps some amount of time to lock. I've also noticed that when you have the GPS lock on your location, turn it off, wait a bit, and have it relock it does it pretty quick. Does the GPS remember your previous location and, for instance, if you turn it off and go somewhere new even if its a few miles away it takes a while for it to relock? If this was the case, would leaving the GPS on at all times actually fix this problem? When you leave it on and go into maps you see the little 'GPS circle' that indicates when you're locked but when you're not using an application that requires it its not there... I assume that if this is the case the GPS is passive and not wasting battery life, but if its in this passive state will it help it to lock on quicker if you move locations?
I'm asking because I've always wondered if I should leave the GPS 'on' at all times because it only uses it if it really needs it, but it will be quick to lock on since its always passively tracking your location. I'm referring to its use in Jellybean but I'm sure its the same in ICS. Thoughts?

GPS should lock fast if AGPS data is downloaded, do you have a working data connection?
Beamed from my Maguro.

Of course. When I noticed this happening I was on 4g. For some reason (it seems to depend on the rom and kernel) the GPS locking is always finicky. Sometimes it takes a while to lock, other times it does it real quick, and sometimes it'll decide to just not find it at all. I recall it happening on ICS as well but I'm running JB roms now.

Try using a app like GPS Status to get a lock before firing up your navigation app.
That's what I do, and it works good.

TouchWiz GPS vs Aosp GPS

Would someone be able to identify why my gps locks quicker with aosp roms but not with TouchWiz roms?
With TouchWiz roms it will usually take 30 secs to 3 mins or even 5 mins to lock.
While with aosp it will be less than 4 secs.
Thank you

In my opinion Samsung's GPS radios suck. I think I had problems with the one in my Galaxy Nexus, probably had problems with my S4, and the one in my Note 3 constantly thinks I'm moving even when I'm standing still! I'll be standing in one place and the 'person' indicator will be moving around in about a 2-3 foot radius of where I'm actually standing. Extremely annoying when I'm trying to play Ingress or use walking navigation.
It seems I have these problems on both TW and AOSP ROMs. Your issue may be due to the GPS config file in AOSP having your country set whereas the TW one doesn't.

I haven't change gps config file in aosp rom. I'm currently running Will slimkat rom. Also tried cyanogenmod as well. Aosp has instant lock while it will take forever for TouchWiz to lock. I've tried different TouchWiz roms as well. All with similar results without changing any settings.
I think it's either software issue or my location. I'm from Canada...

I get lock in under 5 seconds in my house, and nearly instantly outdoors with touchwiz.
Suggestions:
1) make sure the baseband (modem and non-hlos) and bootloader match the firmware revision you're on. (NF1 for NF1, etc)
2) do a factory wipe, power off, but into odin mode, and do a full reinstall of stock using desktop odin
3) turn off gps (location) and wifi in settings, power down phone, pull battery (and sim), power up (without sim), perform the nv reset procedure, then power of phone when prompted, pull battery, put sim back in, power it back up and re enable your toggles and try again.
hopefully one of those helps.

Thanks, I try it out. I get a lock in 4 secs with aosp. So I know it's not the hardware...

Just a wild guess, but could it be that on aosp something else is accessing GPS, before you actually use it and on the other ROM it isn't? It takes much longer to get the fix from cold start, than it takes from warm start (warm being GPS was used very recently and has all sat, time and location info and cold means it wasn't used for a while and needs to update). GPS is not working, unless some program requests the location data and maps are not the only program using it. So for example if Google + is using GPS to report your location just before you're using map, it will be fast due to warm start, if nothing uses it for hours, it will be cold start and will take longer and if cell network access is slow, it will take even longer to assist GPS.
As far as GPS showing standing person is moving 2-3 ft, that's normal, since under best sat. coverage consumer GPS accuracy is about 5-10ft. I did some tests with geological markers and usually if you stand still for about min or so the GPS will keep on averaging and will pin point location to about 3 feet at best. I'm not even sure consumer GPS stores location at accuracy less than 1 yard.

I'm on Touchwiz as well and get an almost instant lock for GPS.
Might it be the rom you use?

I think that might be my problem. I have issue with locking after I boot up my device or haven't used gps for a while. Once the satellites are locked, I have no issues in locking again if I attempt again within short period.
So is there a way to keep the gps in 'warm state'? I usually leave my gps location on by default.

GPS Signal Lost in IGO when not in focus

Anyone else have an issue with IGO, that when I switch to desktop or another app, after a few seconds i hear "GPS Signal Lost"
Its rather quick to re-establish a connection when i switch back but seems weird to not get a signal only because its not in focus.
While in focus its rock solid, never drops out.
Setting or known issue?

Always, but I've been got used and don't care...

Snap. Always does it.
Sent from my Hudl 2 using Tapatalk

It has to be an Android issue I had a Pioneer Navi unit (they use iGO) never lost signal once locked in, well as long as I didn't go in to a tunnel or parking structure, switched to Android and every time I look away it drops GPS but only for a second or two. I believe there is an advanced audio setting to mute the announcement of GPS signal loss, but I cannot remember if it's a GUI option or if it needs to be put in the sys.txt.

Try this settings in SYS.TXT:
[sound.announcer]
gps_signal_lost = 0; disables voicemail alert "lost signal GPS"
gps_disconnected = 0; disables voice notification "GPS turned off"

That may be a viable option, when its in focus i never loose signal....so really its just the voice announcement that annoys me when i switch to another App.

I used to use an app called active GPS, can be set to acquire a gps lock and keep it on boot, not sure if you are really losing the gps lock or if Igo just thinks it is.

Im not losing signal no......Its approx 5 seconds after IGO loses focus and it regains the signal immediately after i switch back.
Perhaps this is intentional to allow another App access to the GPS Signal.....ie only 1 App can have access at once, so they only keep it during focus?
Not sure but its peeing me off
Ill check if theres anything buried in IGO settings or the alternative (Not that i like working around a problem) is to quieten the "Lost signal" audio.

Do you also have a weather widget running with its location based on GPS signal?
Maybe that app requires a temporary connection to the GPS port (that might not be shareable between more apps)...

In Android there is no problem for multiple applications to use GPS signal at the same time. You can run 5 navigation apps and another 5 tracking apps at the same time if you have enough RAM. The OS access the GPS sensor and shares the information to apps.
The question is, what really happens. If you continue with iGo in the background, is it still navigating you? Do you hear the correct voice commands or is it really lost and has no idea where you are?
For me all Navigation application work even in background. They have a service (identified by an icon in notification bar) that runs even if the main app is in background. You should also check the GPS icon in navigation bar to see if GPS is shut down.

I'm not completely sure about the following, but IMHO there is a difference between the smartphones and the MTCB head units for which regards the GPS receiver.
In fact, while generally in a smartphone processor (ex. Qualcomm) the GPS receiver is included in the chip itself, AFAIK in a Rockchip processor (ex. RK3188) the GPS chip is not present, but should be externally connected to the system through an internal serial connection (USB?) and managed by the MCU: for this reason there might be some sharing problems among apps, problems not occurring on a smartphone integrated architecture.

Ye thats interesting coz this morning i had to go somewhere and used navigation as apposed to just having IGO open on Map.
When Navigating to a destination, you can swap to desktop and other apps and it still guides you with no Lost Signal being mention.
So its only when you have maps open, not using a route navigation and you put IGO into the background.
I assume its IGO giving up the lock on the signal for some reason.

Same issue. IGO drops GPS when focus is lost.

That would make sense, it would be a battery saving feature, no need for a persistent GPS lock (that sucks battery life) if you are just following your location on a map (when the map isn't in focus anymore) but when navigating you want the persistent lock so you can continue receiving directions regardless of what app has focus. I suspect a lot of GPS apps act this way, they just don't announce it.

Possibly
Google maps acts that way, with maps open, if you open another app, the GPS icon disappears on my phone, but comes back as soon as I refocus on maps, but if I am navigating somewhere then the icon stays there.

Not that it offers you any help but my gps icon is on all the time regardless of what app is or isn't running.
If the above theory is correct then your answer may lie in the power saving and lox location settings.

But on a smartphone this battery saving behavior doesn't happen...
And on a HU there is no battery at all and no battery saving needs, on Android all apps should be able to detect if the device is on battery power or currently external power supplied...

It does happen, test for yourself, but the battery will drain quicker with Maps open and an active GPS lock rather than when another app is in focus and no GPS lock, that is also why the mode to not use active GPS is called battery saving.
Take that up with the developer, but I doubt they will build in an option that is only useful to a very small number of users.
Personally I don't understand why you need the map window open if you aren't actively navigating somewhere anyway.
