Greetings!
Loving my G3, but when using as a gps in my car when plugged into a 2.4 amp usb car charger it still drains. It drains at about 10% per hour.
Anyone have any suggestions?
I just came across this. Make sure you have latest version of maps and after you start navigation I got a pop up asking me If I would like to dim screen in between turns. Not sure if this is a new option that you can access through settings or if it just pops up if you have a considerable distance between turns. I had a too mile trip and it worked great even played Pandora the whole time. Now my battery never drained but did increase very slowly. Hope this helps you.

Hey what have you guys n' gals been getting off your XDA IIs for battery life. I am away from home just for one night this week, and have forgotten my charger (Must get a sync n charge...but where!!!!) I'm only using PDA functions and Duality Email....and battery is already at 83%
Will it last 48hrs!!!!! We'll wait and see!

Obviously using it as a PDA does use more battery life.
With my phone 'off' (well pda bit off) and WiFi off, over a 12 hour period of inactivity I'll use maybe 5% of battery, so when it comes to bed time your battery use will reduce.
if you're away from chargers I'd advise keeping wifi off, it's the battery eater portion of the functionality. a little light GPRSing shouldnt hurt if you need email, bluetooth isnt a big issue, but if you need to last 48hrs, dont touch the WiFi :twisted:
Also I have noticed that my battery goes from 100-95% REALLY quick (like 10 mins with only BT on), but then takes maybe 30 minutes of wifi browsing to use a similar 5% in the 50% range!?!? non-linear battery consumption maybe? Might be just mine.

I've noticed the same but, conversely, when charging, it takes longer to charge the last five percent than the rest. So, I put it down to the Battery monitor API. These things are never 100% accurate.
As for battery life, two days from normal useage and three and a bit days if I'm careful. I have no problems going for a long weekend and not taking the charger as long as I have no plans to use it intensively.
I find reading an ebook with mobipocket also kills the battery at about 10% for every hour and nearly treble that if I'm listening to music at the same time.
1 Day, its usually down to < 30% come time to goto bed. But then, it gets well used.
So, the question has to be asked..... Who has the charger by the bed?
/me raises hand.
Sync cradle is at work... which charges too.

Battery Life on XDA
If you turn ON flight mode you will find battery life will improve but you will not receive "always on emails".I've got a feeling the phone wont work either (i don't use mine as a phone so not sure).I know when you turn flight mode off again you will have to enter PIN no.
I used this method when I was in hospital for a night and they would not let me charge my XDA.
yeah : flight mode = turning off the phone part
I have a brodit cradle in the car , charges it extra while commuting
As default when you get the phone, it will ask for a pin number. This can be disabled though through the software!
Flight mode will of course save battery - like said - its not using the phone functions which are probably the most battery draining.
I have to use my charger twice a day but i do cain it as my job is so ****ing boring! i hope to god someone invents a....
Solar panel charger
so i can go campin in wales on ma scooter and not need to sneak my phone into the pubs wall plugs all the time
I have a brand new M2000.
I took it off charge at 08:00 this morning.
I got to work at 09:30 and started using it.
I had bluetooth on with headset and I was using wifi on and off.
I started getting low battery warnings at 15:00.
That is very poor
I have BT on and can run from Thursday night through till Sunday without a problem. Though I do get worried about making calls on the Sunday. If anyone has a description of how to convert an XDA car cable to XDAIIs I would be gratefull.
Hello,
I have a HTC Blueangel with a somewhat novel approach to charging its battery.
When connected to the USB, the charge meter continuously _decreases_, something close to 1% in 5-6 seconds. When the meter reaches 0%, it stays there for a short while (20-30 seconds), then jumps back to whatever the real charge is. And start decreasing again. After the regular several hours, the battery gets fully charged as normally should.
The charging used to work normally a while ago, and I cannot figure out what (or when) did I do to make it act this way. Initially I thought it might be a software problem, tried a hard reset, but it's still happening.
It's running WM2003 (1.42), with radio 1.15. BlueTooth, IR and wifi are disabled, screen brightness is set to min, etc. so I cannot understand what is going on.
Normally it should not be much of a deal, because the battery really has charge in it. But the system believes the indicated meter, so when going really low on the battery meter, it decides to disable stuff like phone, SD slot, etc. trying to conserve an apparent lack of charge.
If I disconnect the USB cable, the charge meter appears to drain at the normal rate (regardless of what the _real_ charge is). All other battery-conserving features appear to function normally -- notifications at 20 and 10%, shutting down when empty, etc.
I do not have a wall charger, so I could only test USB charging. I do not have another BA available to test just the battery.
Any ideas as to what might be going on? Is it possible to fix it?
Thanks,
-Daniel
lol sounds annoying........what about reinstalling wm2003???
i am having a similar problem - using the usb charger while in the car seems to discharge the battery. nothing seems to fix battery drain problem - but on the cradle it is fine. let me know if you find anything on this one
ok my battery has good days and bad days. I have now tried something different and it seems to have worked for me. When I wake up in the middle of the night and the light is green i unplug my phone from charger. Then when i wake up four to five hours later it is usually around 95%. In the past I let it charge till I woke up then I would send a text or two a quick call or check email and it would drop to 88% or 90% in minutes. But now that I leave it unplugged for about five hours I get up and do what I usually do and battery doesn't seem to drain as quick. My question is why does this happen???? Strange that before it would go from 100 to 90ish real quick. now i start off at 95% and battery drains slower.
My battery is absolutely horrible. I unplugged it today n within minutes it was down to 93% n i didnt even use it at all. I have GPS turned off, wifi is off, 4G is off, friendstream is gone, i have everything set up to sync manually so idk wat the deal is.
If you are running a custom Rom you should do a search in the dev section for how to calibrate your battery.
it is stock rom. I have tried every battery trick. you could think of even the one someone posted from htc. none have work but for some reason this seems to be giving me better battery life. and i am just wondering why and sharing for other people to maybe try.
nothing new under the sun. a search would have revealed the following posts...

it sounds like voodoo, but based on the battery graphs before and after...it worked for me. the upgrade to 1.47 and 2.5 baseband seemed to help quite a bit too.
Strange battery design
OK it seems odd that the EE's who designed the phone specified a 4.2 volt charging cut off to the battery, and a 3.5V battery. It was probably to limit the heat production by components regulating internal voltage.
SO we can either up the charging cut off by rewiring a charger to use the feed but not the sensor ( 4 tabs on a battery), or get a battery rated a a slightly higher voltage ( which would only be partially charged due to the HTC charging algorthym). It may be that the recycling on /off specified by HTC ignores the sensor reading.
Normally I charge my phone nightly right before I go to bed and don't plug it in at all during the day usually.
I have noticed that on days where I have to use my phone heavily and require a charge midway through the day for the next week my phones battery life is almost cut in half. If I charge it regularly at night for a week or so the battery life will go back to normal. Has anyone else noticed this behavior? I'm trying to figure out if this is an incredible issue or an android issue.
Another thing I noticed is that under the battery stats it lists that my awake time is 43 hours. Its just slightly less that the up time. This makes me think that my phone isn't going to sleep. Anyone know how to tell if my phone is sleeping or tell me which app is keeping my phone from sleeping?
Install this app

Go to partial wake. in one of the drop downs.
I checked the partial wake usage and I don't see anything out of the ordinary.
I actually have an update to the situation. As a last resort I wiped my phone and loaded Cyanogen 6.1. At first it was working awesome. Battery life was awesome but as time went on the battery life got worse and worse and now i'm back where I started.
It sure seems like there is software problem with the way the phone tracks the battery usage/charging information. As I said it seems like charging the phone midway through the day or charging the phone before the phone is dead seems to have a negative effect on the battery. I don't get it. Letting the phone completely die isn't realistic. Charging the phone when I go to bed without affecting how long the phone last after the next charge should be totally doable you would think.
Does anyone have any suggestions or insight that might help me out.
You don't say if you charge with the phone powered off or on. But sound like you're always charging with the phone turned on.
I don't think the phone charges fully while turned on (to prevent overheating maybe? ).
If you can, I'd suggest trying to charge with the phone off, at least during the nightly charge.

Yes I do charge my phone while its powered on (like the rest of the world). I don't know anyone that turns their phone off to charge.
My phone is paid for by my company so that they can get ahold of me in the event of a server failure or some other IT related disaster. If the phone was off I wouldn't be able to receive those important calls.
I can't believe no one else has witnessed this type of activity with the incredible. I have tried 2 phones (replaced for an unrelated reason) and 3 batteries. The behavior seems like a software glitch. I have noticed with with both AOSP and Sense Roms.
Does anyone have an in depth understanding of how the battery system works on this phone. I also have an Iphone and the battery life compared to my android phone is ridiculous. I would use the Iphone exclusively but it doesn't do everything my android phone can do. I'm hoping there is a way to fix this.
Well, now you do know someone who charges with their phone off. Me!
I'm in IT as well and on call one week per month. But we don't run a third shift, so late night calls are almost never, and they have my land line number.
Back on topic, I have experienced better battery life while charging with the phone off. Maybe you can get an external charger until a solution is found.

Well i'm on call 24/7 and I don't have a landline.
What do you mean by "get an external charger until a solution is found." Do you mean a second charger to charge during the day? I have plenty of chargers. Thats part of the problem. Charging in the middle of the day I believe is causing the problem. Until a solution is found? Are you saying there is in fact a problem?
Having to leave my phone plugged in all day kind of defeats the purpose of having a wireless phone don't you think?
Please...anyone have any knowledge of how the charging system works in android and specifically how it might work differently on the incredible?

I should have said get an extra battery and a stand-alone charger that allows you to charge the extra battery while it's disconnected from the phone.
Have you read the thread in general titled 'your battery gauge is lying to you'. (or something like that). Good read. Also there's hundreds of other threads on the inc's battery issues. Well known problem.

If your up time and awake time are essentially the same, you definitely have something running in the background. Try menu/settings/applications/running services and see what program might be running that shouldn't be. You can also use an app called System Panel to do a comprehensive survey. I recently had an update that resulted in the program running continuously in the background, affecting my battery life.
Some other threads have discussed that after 40+ hours of up time, their phone goes into max CPU usage all the time. Again, using the app System Panel, I confirmed this for my own phone at 45 hours. My ROM is the stock Froyo 2.2 with a custom kernel. the simple solution is to power off/power on the phone which resets the uptime.
My routine is to charge the phone with power on over night so I can use the alarm. When I get up in the morning, I power off the phone and bump charge it for about 30 minutes until the light turns green again. Then I'm usually good for about 10 - 12 hours of uptime with 3-4 hours of awake time using a 1500 battery. That time can also be reduced considerably if I'm receiving a poor 3G signal.
I did originally have a problem with a program not allowing my phone to sleep but I have since uninstalled that program and now my wake time numbers are where they should be. I think the remaining battery issues are a result of me having to charge my phone in the middle of the day as a result of the misbehaving program prior to me uninstalling it.
It almost seems like the the battery in the incredible has a memory. On a hunch I have started completely discharging my phone completely everynight before I put it on the charger. As a result my battery life as almost doubled. When I get home at night I start playing angry birds with the brightness at full until the battery gets to about 3 percent left. This obviously isn't a permanent solution but It certainly sheds some light on the root of the problem.
Prior to doing the full discharge I did a bump charge and wiped my battery stats. The battery is working great now. I wish someone would create a kernal/rom that has this issue resolved. Since these new lithium batteries aren't supposed to have a memory anymore I'm thinking it has to be something that the OS is doing with the battery stats file.
According to this article you should fully charge and discharge once every 30 or so charging cycles to resync the battery meter with the actual battery voltage. So maybe the complete discharge fixed your problems.

not sure if this will help or not, but i have been running advanced task killer ever since 2.1(haven't gotten around to uninstalling before now, ha ha) and recently uninstalled it and installed watchdog task manager and my battery has increased two fold!
just my two cents worth.
I'm running CM10 10.0 Stable and the latest Lightening ZAP Kernel.
I've always had problems with battery life that are somewhat random. Sometimes my phone will last over 24 hours with the same usage as when my phone decides to die in 8 hours. This is very concerning because I know a phone should not be this random with the same apps and usage charge after charge.
I've relentlessly searched for the wakelocks that keep this crazy phone awake using BetterBatteryStats, CPU Spy, Battery Monitor Widget and GSam Battery Monitor. My average charge time on a rooted stock 4.0.4 was about 20 hours. My average time on CM10 stable is 8 hours. I now carry around an external USB battery all the time because of this with a wall charger and multiple micro USB cables in my arsenal.
Now I'm playing with undervolting but I know that's not getting to the source.
My phone does seem to go into deep sleep when unplugged but only 50% of the time. I've read that VBUS_PRESENT is when charging with a non friendly charger. Well I've been using a stock Samsung charger that came with my phone and it still shows up. WLAN_RX_WAKE I'm totally not sure of...it uses a huge amount of time keeping the phone awake why?? I'm not sure. It didn't used to do this and I leave WiFi, Data, and Syncing on. I have the same outcome whether Google Now is on or off as well.
Any help would be really really appreciated. I think I have battled battery run time since I started using Android. I wish it wasn't like that because I love the openness of the operating system compared to iOS which I have used in the original iPhone and every generation up to the iPhone 4. If you guys require screenshots I'd be more than happy to give them. There are so many smart minds here that know far more than me and I know it!!
I'm having the same issue running Gangnam Style CM10 on my Evo 3D. I'm seeing huge wlan_rx_wake wakelock that I haven't seen on any other ROM (same networks).
Apparently, it's multicast network traffic that the phone should ignore, but instead wakes up and replies.
Sucks.
Hmmm strange. I reformatted my phone and wiped everything clean...and reinstalled CM10 stable with the newest lighting zap kernel. But now the phone app is taking a massive amount of power from wakelocks and CPU. My phone is left with a higher than average CPU idle running at 1566MHz for 40% of the time before my battery dies at 10%/hour. Something is really up and I can't figure it out. I know that when my phone was operating at 4+ hours per charge the temp would be under 30C. Now running at idle it's 33C. I normally never feel the back of the phone heat up near the camera LED but now it sometimes feels warm or hot when it's deciding to try to deplete power within a few hours. This is a strange thing....I don't hear of people with CM10 having this problem...or does everyone think having an 8-10 hour burn time is normal?
Just switched to Slim Bean ROM (JB) and still have wlan_rx_wake jamming me up on wifi networks.
u guys need to change the settings under the advanced menu to tell your phone when to enable/disable WiFi sleeping, the delay amount, that's what the wlan_RX wakelock is
as the op stated,vbus is indeed when using a charger other than the stock Samsung one that came with your phone
What should the delay amount be? I used to have it set to 5 minutes under "only when plugged in". I use my OEM Samsung charger and nothing else but I still get vbus.
I just did a test and turned all data and wifi off. Battery drain has been completely normal at less than 1%/hour. This is great so now I need to find my internet culprit. I get the same type of nasty battery drain with Wifi on, Data on, Wifi & Data on.

I'd rather have the wifi never sleep. Why use a low speed, higher power radio (3g) when you have access to a wifi network.
Wlan_rx_wake never kept the phone awake on gingerbread ROMs.
