HTC Desire Battery Life

I have a question regarding my battery life. Yesterday night at 10:00 pm i played +/- 40 minutes on games like Angry Birds and used my 3G connection for about 10 minutes. My battery dropped from 100% to 61%. When i didnt use my phone (just idle mode) @ 11:46 pm i wanted to check how much battery i had left today in the morning (10:00 am) ..... it whas completely dead 0% .... i have this phone since august but if i knew the battery life whas so crap i would have picked another device.
Is there a way to improve it ??? since i read in diffrent topics people can use their desire for 2 days without a recharge.
- Not rooted
- Froyo 2.2

The HTC Desire is a smartphone running powerful mobile OS and a lot of additional gadgets like GPS, ...
So comparing battery life is impossible.
You can get a battery life of a mobile phone/week if you use it like a mobile phone: No GPS, no data, no playing games, no surfing, just occasional talking. So the battery life is normal and good, compared to mobile phones.
But normally you use it like a smartphone, thus you use it daily, play some games, ... which results in a battery life of a few hours (navigation) up to two or three days (moderate use), with an average battery life of a day (heavy use).
However, one thing for sure: Something is wrong with your phone.
This dosen't mean something is broken, rather you use an app/setting, which causes the battery drain, so you did something wrong, you're the failure, not the device!
Playing a game drains the battery fast. The display is on, probably max. brightness and the CPU and GPU is working like hell. It also gets warm, so you can feel the increased power consumption.
In sleep mode however, it should consume much less than it did for you. Maybe 2% each hour.
So to find what app you've installed or what app you keep in the background running, install a program like Android System Info and take a look at the task list, CPU load should be around 10% if you wait a few seconds and do nothing.
Take a look at the running services (android settings, applications, ...) and check if you really need all of them or if an app is active which you don't use. Then don't force close it, only idiots do this, rather open the app and deactivate the service (like automatic updating)
Next option: Test the battery life again. Maybe an app crashed and caused the increased power draw and now everything is working fine again and battery life is normal again. Then it's impossible to find a culprit with Android System Info.
Also tell us what settings you've activated: GPS/Wifi/Data/BT/...

This is happening because, some process not letting your device to sleep..!!
All you need to do is type *#*#4636#*#*
and check the battery history ,you'll get to know which process is using your battery, and remove that application.

Brightness is already said to medium, i also turned of those life wallpapers and it still drains like ****. When i look at the battery status it says battery life is good. Maybe a application that is running i dont know, ill try to find it out. So far i have a few apps installed which i rarely use.

Thanks will check it out and see what it does now in idle mode.
Idle mode 01:28 pm starts now, will post results in a few hours.
Edit: It's 02:00 pm here and i already lost 4% battery, its 96% now , i did *#*#4636#*#* and checked battery status and it seems wifi is in full use 99.7%. I will turn this off but what about the 3G connection
Edit2: It's 2:24 pm here and the battery status is 92% now, i reveived +/- 4 emails in that time. I checked the status in battery indicator pro and this is what it says
Android system 37%
Mobile Stand-by 22%
Phone inactive 15%
Wi-Fi 15%
view 11%
nothing else......i am really lost now.

Is my battery damaged/broken ? .... how can i reset/callibrate the battery ? or should i contact the shop where i got this phone from for a new battery ?

don't worry, lots of people are having bad battery lifes, and angry bird drain your battery really quickly, so it is quite normal, especially on AMOLED desires.

Yeah i have AMOLED
PS: After 30 minutes without touching it the battery is still 92%.

you could install setcpu and set profiles to save battry life

Might try that.....but after 1 hour the battery is still 92%.....i guess wifi drained my stuff down all the way as i am pretty sure i turned that thing of last time.
i will do some more tests later....
Edit: After 1 and half hour the battery is still 92%, guess the stock rom isnt that bad .

Its not 5:09 pm here and the battery is now 91% (idle, not touched)....guess wifi what the bad thing on my phone.

Tested the battery last night and must say i am happy with the results
10:00 pm yesterday the battery whas 60%, today i looked back @ 11:24 am and the battery just dropped with 10% (3G is on), i didn't touch the phone since then.
Stock Rom / Froyo 2.2
The battery drain came from wifi

I wrote HTC about the battery and they just sent me a brand new one So now I have 2 batteries and I think I'm happy DD

You can check your battery usage with a widget called "currentwidget" (search for it on this forum)
Usually on SBY with radio ON my phone drains from 3 to 4 Ma and 2ma in plane mode. (sounds good with a 1400mah battery)
In heavy usage, it can go anything from 150 to 500ma (ie: playing game with wifi ON)!!
For nice graphics, try to install "battery snap" too.

From HTC themself:
“To also help with Battery Life you can do these steps exactly:
1) Turn your device ON and Charge the device for 8 hours or more
2) Unplug the device and Turn the phone OFF and charge for 1 hour
3) Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for another hour Your battery life should almost double, we have tested this on our devices and other agents have seen a major difference as well“

A known problem with the new update of the HTC Desire to Android 2.2 Froyo is battery life. How users have experienced the change is highly variable. Several said that battery life has improved, some even talk about a major improvement. The others have had problems that the phone charges from a fully charged battery several times in one day. If you have experienced such problems, there are measures, some simple, others more complicated and time consuming. Below I list things you can try, the lightest at the top.
# 1 Look what it's drawing power. Go to Settings> About phone> Battery> Battery usage or enter * # * # 4636 # * # * on the keypad and look around a bit. Is there anything that seems abnormal, or any program that seems to be the culprit, uninstall simply the application and see if that helps. While you can uninstall applications you believe is in the background and drag the cream from the phone's battery. Some applications may slip into the "Android System" in your battery history.
# 2 Uninstall system control and task killers. Advanced Task Killer and similar programs do more harm than they help. It is unfortunately only to realize this and stop using them. Android is an OS made for having many applications driving on the background. The operating system puts himself applications you do not use the idle to conserve battery power. Different programs that measure your performance on the phone, for example, Task Panel never sets in idle and therefore system resources continuously. If you have such software installed it may be time to consider uninstalling it. More on why the task killers and Android do not go hand in hand in to read this article by Android developer Dianne Hack Born.
# 3 Clean your home screen. It can be a good idea to try if it helps to clean up your Home screens from various widgets.
# 4 Do a soft reset. Discharge the battery completely (not that the phone is turned off), turn off the phone manually, remove the battery and reinsert it, restart your phone and put it on charge. This may have some effect and provide an improved battery life. Such a restoration known as a soft reset and should be tested before you do a master reset (hard reset).
# 5 Do a "hard reset". Have you done all the methods above are still not noticed any major difference? Then it's time to do a master reset of the OS. HTC have said they for some users might went wrong during the update to Froyo causing poor battery life, and when it is easiest to do a reset to get to grips with the problem. Although Android automatically sync contacts in the "cloud" so it might be a good idea to make a backup of your contacts (Contacts> Menu> Import / Export). Note that when you do a hard reset resets the entire phone, including messages, settings, themes, installed applications, etc. These are not the contents of your SD card. There are two methods to restore your phone, do a google search on "hard reset desire," so there are many simple guides. After restoration, the idea not to install any applications you had installed before. Install the programs one at a time and not too many at once.

[Q] "Android OS" and battery usage

Hello.
Sometimes my phone works normally about 25hours, sometimes it works twice shorter ~10 hours. I've analyzed battery usage and found out that only difference in Android OS process.
25 hours battery usage
Display - 60%
...
Android OS - 4%
10 hours battery usage
Android OS - 60%
Display - 15%
This definitely looks like a bug. OS should not use more than a display.
Is there any way to found out what is Android OS in details?
Why it takes to many power?
P.S. I guess that bug is triggered by programs like Google maps,
but can't definitely confirm it.

Is there a way to shut off maps till needed?

Get spare parts and you can check what is using what. It could also be useful to get watchdog or similar app to check if you have any apps gone crazy. It isn't unusual though that the screen usage is lower if you just haven't actually used the phone that much as the percentage is always 100% and is divided among the things that used the battery, thus the usage percent doesn't imply mA usage.
Sent from my Desire HD using XDA App

I have still pretty high "Android OS".
Display 31%
Android OS 21%
I've tryed Spare parts (Battery history), but it doesn't help.
It just doesn't display such name.
Is there any other way to find out whois is lurking
behind this mysterious title?

I'm betting you have a "suspend process" issue.
What does Battery history from spare parts say? Choose CPU usage, Since last unplugged. Is "suspend" close to the top? What CPU usage details does it have (if you select it)? Obviously look at this data at the end of your phone's battery life, before you plug in.

Also what rom are you using? With cm7 it seems that the battery stats are quite crazy and don't seem to add up to the actual usage, it's been discussed a bit in the nightly thread. The inaccurate stats don't explain the changes in actual battery drain though...

just to be sure, you have usb debugging enabled right?

I'm on official ROM (no root) with USB debugging enabled (I confirm init issue).
My last guess that "Android os" caused by "Location -> Wireless networks".
Now have ~2 days uptime without ever running "Google Maps" and with "Location -> Wireless networks" constantly unchecked.
P.S. Spare parts constantly eats about ~3% CPU at top. Too many for battery monitor. Removed it.

Hey, since you're worried about slight additional CPU-usage and overall performance, you really should consider S-OFFing and getting a different Radio and a custom ROM like ARHD. Or at the very least flash a new kernel, Buzz' kernel did wonders for me.

[Q] [ROM] Revolution HD: Dialer drains battery, same fix as in CM7 possible?

Hi,
i have changed from stock to Revolution HD today, because the dialer of the stock rom (since the GB update) drains my battery up to 50%.
But the problem is not fixed with Rev HD. My Dialer is still the top 1.
Is it possible to fix this bug in the same way as the cyanogen rom has fixed it?
Here is the thread:
http://forum.xda-developers.com/showthread.php?t=929054
And here the changeset:
http://review.cyanogenmod.com/#change,3904
Or is this option available in Rev HD?
Home Screen > Menu > Settings > Call Settings> Turn over silence
I could not find it in the specified settings.
I have no apps installed. It is a fresh image of Rev HD.
I have read the linked battery threads too, but i think it looks like the same problem as in the CM7 rom.
Many thanks.
Kase
edit: I am using it on the Desire HD

There's been some discussion around this and in my opinion (which means it could well be wrong) it's not an actual issue.
I don't experience any more battery drain when Dialler is listed than when it isn't, and the details for Dialler in the list typically show it as only being awake for a couple of seconds over a full day.
Personally I think either HTC (or google or whoever) have combined several system processes and listed them together as "Dialler" making it show higher up the list, or it's a bug in how they calculate battery use in Gingerbread.
It might well be that it's continually using the sensor as was presumed in cm7 but I would expect to see more evidence of reduced battery life that were the case.
As I say, I might be wrong

Hi hopscotchjunkie,
thx 4 your reply.
I am very sure that it really drains the battery. I have tested it a few times with the stock GB rom.
If i reboot my phone and never do a phone call, the dialer is not in the list. My battery time increases from 2 days to at least 3 days on low usage (only 3g on, but auto sync off). With Froyo, i always had up to 2.5 days (and no dialer problem).
Maybe you can test it too (i know it is hard to reach 2 or more days without phone call )?
I will install CM7 the next weeks (if i have some free time), and test the battery usage with this rom. But comparing 2 completely different roms is very inaccurate i think. But i will give it a try anyway.

I know whilst the problem may sound related but just to be on the safe side of things, ensure that you have the recommended Radio and the compatible RIL installed on the phone. The Radio and the RIL will vary depending on the ROM that you use, and as far as I know both AR and CM7 all have listed their recommended Radio. The RIL you will have to match depending on the version of the Radio. Both Radio and RIL library is avaliable in this forum.
As others have mentioned possible bug, once the phone has been fully charged, go into CWM and clear the Battery Statistics. This will allow a sort of "restart" for the battery life articulation.
I am using CM7 (with custom kernel) and generally speaking, from what you have described, I havent had such issues before with either ROMs, although the last AR I used was prior to the 2.3 releases but have since been with CM7, noticably higher benchmarks, possibly better battery life, but definitely free up more RAM, which I suppose = better battery life?

Try This!

Disable all the three, worked for me! - Im getting about 3 mA in standby = 2 % Usage over night.
BTW: I`m running a DHD with Revolution HD 5.1.9 (No-sense++) with the ADW Launcher EX - Recommended!

I'm running ARHD 5.1.9 with nosense++ and launcher pro Plus and i don't experience the problem.

Wow, you battery is a beast if it can last up to three days, no matter how little you use the device. Back to the topic, it may be worth backing up your settings and try a factory reset, although you probably did in first place when you installed Revo HD. You may want to look at uninstalling Sense dialer and get a replacement and see how it goes. There are a few good ones out there.
I hope it helps.

Hi all, thanks for your replies!!!
I have done some tests now with the AR 5.19 ROM.
If i reboot my device and do not start the dialer, the phone drains my battery 15% in 10 hours. No usage, only 3g on with whatsapp and icq, but no messages written at all. I have tested it many times with different battery charge levels, its always about 15%.
=> Battery usage: 50% phone standby, 50% phone inactive (i dont know the exact english words).
If i reboot my phone, start the dialer, but still no usage, same conditions, the phone drains the battery about 30% in 10 hours. Also tested many times with different battery charge levels.
=> Battery usage: 50% dialer, 25% phone standy, 25% phone inactive.
With the dialer, my battery is <10% after 2 days of low usage. If i reboot the phone and never start it, my battery is ~40% after 2 days, same usage.
I am very sure, the dialer drains the battery with the exact amount displayed in the battery stats. It matches 100% for me.
@0semaj0: I use the recommend RIL and Radio for AR 5.1.9, i have done a full wipe before and cleared my battery stats.
@HeiDuDer: I also tested this, deactivating the 3 options you have described does not change anything, the dialer is still in my battery stats after i used it at least once. Even after reboot.
@fdelosriossanchez: I will give it a try. If i use the nosense script, do i have the stock dialer??? Maybe i will test AR 5.1.9 with nosense.
I will post an update in a few days. Thanks to all!

Bumping this with my own observations, deactivating the 3 options doesen't have an effect on the battery life, and the battery drains far faster after a reboot if I make a single phonecall to start the proximity sensor polling bug

[Q] Battery issue : software or hardware ?

Hi everybody,
I'm facing with a big issue since a while with my battery life. The battery is draining very very fast without visible reason...
I've tried everything to spot the problem but I now wonder if it is not an hardware problem (died battery).
So how can I know if I have to replace my battery or not ?
Thanx
P.S : sorry for my english

There are lot of recommendations to improve your battery life, have you tried them? Explain more about the problem.

What I've tried :
- Calibrated my battery with all the the existent tutorials but it doesn't shut down at 0% (but not my biggest issue)
- Installed current widget and studied the current log which showed normal values (5mah in sleep) with few higher values
- Installed Better Battery Stats which didn't spot problem neither in ''Process" or "Partial Wakelocks"
My current set up :
- Latest Oxygen rom, with recommended kernel and radio
- Set cpu ==> wake up 245 - 768 (ondemand) / sleep mode : 245-384 (powersave or ondemand)
- Automatic luminosity
- I manually switch off 3G every time I turn off the screen
- Synchro : mail (every hour), facebook (every 4 hours)
In general, my battery last 8 hours even if I don't use it a lot...

Did u try to use a different Rom.
I had the same thing with Oxygen. Just went to ICS and now everything last even longer.
I also got stunning results with a MIUI rom, about 2 days of usage.

Yep, approximately the same results with every roms (aosp, sense and miui)

I would try CM7, anyway how old is your phone? and for how many time you 've been with this trouble?

I already tried cm7
I bought the Desire at his launch so about 2 years ago. I've been with this trouble since 4 month approximately...
I am more and more convinced that this is an hardware problem (my battery may be dead)

See in Battery Stats what exactly consumes . Screen is very hungry , even on automatic , after that comes phone calls , wi-fi , data transfers

Why opening a second thread with the same problem????????

I already checked several times and indeed the screen is very hungry (40 to 70%). Then, comes the wifi, cell standby, android OS, phone idle.

battery draining too fast new or old

im on a stock rom not rooted and new battery and old battery both discharge really fast. Totally dead in 5-6hrs light use. Im guessing there is a hardware issue with the phone as this isnt normal. Any ideas?
lets see I did a factory reset after Jellybean update
changed the battery for a new one
biggest power drain is showing up as screen 33-39%
I have the thing on power saving mode and mobile data I turn off when not in use.
only thing I can think of that I didnt try is flashing another radio. But I doubt thats it because ive put it in airplane mode and it still looses power fast.

Get Better Battery Stats and check your wake locks. A lot of information in that thread. Might have a rogue app draining you.
Edit: also screen on is always going to be your biggest drain. Keep brightness down as much as you can. App called screen filter is good for achieving lower brightness than system allows. You could try the ktoonsz kernel, undervolted as well. Turning off sounds in settings (key press, vibrate, etc as well). Toggle data and WiFi when not using. These are just some basic suggestions.

This is my second s3 and the first one never had a problem going 10-12 hrs normal use. Im thinking it is a hardware issue as I did a factory reset and it still persists on fast draining.
Edit.. I just disable google talk maybe that was causing it?

It's not Google Talk. Check your battery and it'll show you what's drainage ng it the most. Also check screen brightness

well after the screen 40% we have android OS @ lower 30%

Do you have an SD-Card in?
I was getting the same battery life, took out my SD-Card, and I'm getting 7 hours on screen time with stock battery.

lol sd card?? well I tried it anyway and no, it still drains like a pissing racehorse. Ive noticed this phone gets pretty warm sometimes even with light use. Im not sure what is causing this but must be a factor in why the battery life is so poor. When I talk on phone, not very often, the ear piece actually gets hot. Im gonna send this puppy to samsung and see what they can do.

GSam Battery Monitor can offer better details about your battery usage, including wakelocks, cpu usage, etc.. It's more detailed than what Android offers.
I'd also recommend using an AOSP based rom as they include out any carrier/Samsung services that may adversely affect your battery life, particularly in a fringe coverage area or with many sync and push items. I'd also stay away from powersave mode for the time being.
If you want to know for sure, I'd do something like this:
- update PRL on current rom
- wipe and format everything in CWM
- flash rom as per developer suggestions
- wipe battery stats
- boot and do not sign in with your Google account (very important!)
- do not install or restore any apps
- turn off auto-sync and leave data on
- enable auto brightness
- confirm that phone signal is somewhere between -50 and -90dbm
- turn off phone and charge overnight
- turn on in the morning and use normally for the day
- install GSAM if issues persist
Please post back with updates.

It could be a hardware problem also you know.... if something ground off in the phone then the battery will drain faster than anything....I had a n96 with a grounded problem and it use to dead in 4 hrs....
