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.

Hi all, just visiting from the gnex forums. My wife has a desire running the official gingerbread rom. She has a recurring problem whereby she'll power off the phone and it appears to shut down but will still have a grey tint like the screen is still slightly lit. Last night from a full battery it had permanent screen on in the battery stats and was near empty in the morning showing a constant drain all through the night. Has anyone had this issue?, is it related to the gingerbread update or is it just a rogue app??
I've attached an image of the battery stats with the night period being the steep drop on the right...
Any tips or advise is greatly appreciated....
Probably a rogue app. Search for Better Battery Stats app here on XDA to help you see what's keeping it awake.
Furthermore, try disabling fastboot from settings, don't remember which settings, but it should be in there somewhere.
Thanks for the replies. I've got that better battery stats app and just need to read up a bit on how to use it then I'll give it a go tonight. From my searches I found multiple things suggesting it could be an app but it seemed odd to me that it was preventing the phone from powering off and not just preventing it from sleeping.
Regarding the fast boot option I've just found that and it was turned on - what is this option for and why could it cause this problem then? ....
On Better Battery Stats, I usually check Partial Wakelocks - Since Unplugged. Most processes should be below 1% from what I understand. But it will depend on how long you are using a certain app. If you see a process that's been running for so long but you've just used the app related to it for a relative short period of time, then you check that particular app. Maybe the sync option is too frequent or it's just really poorly coded app.
If it appears that a valid android process is the one eating the battery, then an app is probably keeping it awake and you may need to dig a little deeper to figure out what app is causing that.
Regarding the fast boot option, all I know is that it's a feature to reboot the phone without going through the main HTC logo animation. So it's really like rebooting the phone without actually killing the background processes. (Not sure about it though maybe someone can explain this.)
Basically, with the Fastboot option the phone never REALLY turns off, it's a little bit like it's on hibernate, that's why it can boot a lot quicker, as it skips the bootloader and goes straight to booting the system.
Thanks guys. With the fast boot turned off it didn't do it last night so I'll try with fast boot turned on tonight and see what happens - try to confirm what's happening......
Many thanks for your help!
I turned fast boot on again yesterday and the fault occurred again overnight. Went from 100% battery to 55% overnight. Pictures of the stats for useage during this period are attached.
Anyone know what this alarm manager and sleep broadcast are?
Hey everybody,
Just made the jump from the iPhone 4S and have done the custom ROM/kernel thing the past week. Things were good at the start but I feel them slowly deteriorating.
I find my battery life during sleep has become much worse than before. I mean, it still kills the 4S which would see ~25% overnight. But I'm seeing 10% overnight right now, and was ~2% earlier in the week. I normally have my phone on the charger at night, but didn't last night and I'm kinda glad I got to see this. Makes me realize why I was likely chewing through more in the day too.
You can see what I'm running below in my signature. Last night I had 5 instances where the phone woke on its own. Likely due to emails coming in.
Am I expecting too much from my modifications? Am I doing something wrong? I'm ready to toss AOKP aside because of other issues anyway, but yesterday I also read it was known to have some excessive battery drain as well. Without turning this into a battle to defend the ROM you use (like half the threads in here), if you have other suggestions, feel free to throw in a ROM suggestion. I'll attach some pictures of my battery screen so anyone willing to give me a hand can help.
Thanks in advance.
I had this problem when I was running franco too. Switched to leankernel and never looked back. I get about 4-6% drain overnight as long as I dont do something stupid like leave something running by exiting with home instead of the back button. I also have wifi on 24/7 and gps off unless im nav'in. No BT

I'm hesistant to blame the kernel. I was using franco prior to AOKP without issue. I didn't make that clear in the OP. I went 4.0.4 Stock -> Stock + franco -> AOKP b31 + franco. Things were good the first two steps and I'd like to think the first few days on AOKP.
Perhaps I have some background processes chewing battery - but there's nothing with a higher battery drain than Chrome beta with 2%. My phone idle and Cell standby had huge drain though. Could a weaker than normal signal cause this? Could my radio be the culprit?
Steps to best diagnose idle battery drain.
-Install CPU Spy and Better Battery Stats.
-Charge phone to full and let it run for several hours undisturbed (easiest to charge before bed, then unplug it when you know it won't be used till morning).
-Take quick note of your % loss per hour. Around 1%, you're golden. 1-2 is pretty normal. >3 and you've got issues.
-Launch CPU Spy. Most of the time should be deep sleep (we're talking about 95%). If your phone has been awake a lot, there's either an app that refuses to let your phone rest, or an OS/Kernel issue. If it's not extreme but noticeable, you likely just need to reign in settings on some apps to keep them from syncing so often or working in the background.
-Launch Better Battery Stats. Select Partial Wakelocks from the menu. These are all cases of apps waking the phone up, sorted by length. Go look at problem apps' settings/consider uninstalling if you don't need them. Kernel wakelocks should be low too.
Keep in mind that the goal here isn't really to get all these things to zero so do not obsess over small showings. Facebook with push notifications but updates set to never keeps my phone awake for about a minute or two every night, for instance. So does Handcent SMS. If you flash a rom and your phone needs to do a lot of syncing it's likely to show up in this kind of test as well. But for a night with nothing going on, nothing should be keeping your phone up for more than a few minutes total.

Weaker than normal signal can kill a phone battery, when I'm in lecture out in the bumfuck nowhere school I go to, I get -100 to -120dbm, which kills my battery while i'm at school. If thats your situation not much to do besides hope radios may increase your signal, but if not then your basicly as SOL as i am and may have to just charge it

This is what every user should use to diagnose battery problems at first.
Ok, so I've been dealing with this issue for a few months now, seems software related because it will go away when I flash a new rom, but then come back eventually.
I use Battery Monitor Widget to see my current charge/drain status in mA (only widget I've seen that does so), and even plugged in, the battery is draining (USB or AC). Looking at my battery usage this morning it was something like 5.5 hours on battery, with 70% coming from screen, which had only an on time of 50min. I had it plugged into USB (no AC adapter here at work) and was watching the battery drain a percent every 30-40sec, with a usage of -900mA. I can't for the life of me fathom what could be drawing an amp on a phone that's just been sitting doing nothing all day.
I don't understand the wakelocks, partial wakelocks, alarms, etc that most of the battery threads are talking about - I know I need to install Better Battery Stats to get at them. But how do I track what's using all this juice?
Thanks!
What ROM are you on currently?
Sent from my SPH-D710 using XDA Premium 4 mobile app
Currently running Touched by S4 2.1. Same issue on Blue Kuban, PA, PACman, and a couple others. Again, starts days or weeks after. Today, even after a restart, it kept draining, even on the USB charger. But I turned it off, let it charge to about half while off, turned it on, and it continued to charge. Its haunted I tell ya.

I would install Better Battery Stats fully charge your phone and then check the app when the battery is low. You can check all the options. Other, Kernel Wakelock, Partial, Alarms, What you should see is a time of how long each app/process has had a wakelock. For alarms it will show you how long each app has woken up the phone. You want to look at the items that show the most time usage and most wakeups. If the name is not recognizable you should Google it. Sometimes it could be messaging or social apps keeping your phone awake or anything else. If you need help you can post screenshots of your results.
The app has little question marks you can click on to get explanations for some things. Partial wakelocks is the first place to look, imo.
My battery will completely drain after <10 hours while the screen is off!
However I was able to find out thatquickgooglesearchbar is always the top app.
Those screenshots are a bit old but it's still the same thing, I did manage to root it today, and I was testing Greenify which did nothing even with the Xposed modules, service disabler apps just did not show that specific service for some reason. I was able to remove the widget with Xposed GEL settings but it was still running even though the widget wasn't there.
So can someone please help me out here, maybe the search bar isn't the problem but I just want some battery life.

search and install betterbatterystats (read the whole first post) and it will tell you if its wakelocks etc.
Service disabler apps will need a setting to show system apps (or something similar) ticked or switched to etc.
greenify system apps in greenify also needs to be selected. You may also need to cut wake up paths to get it to stay greenified.
You could alternatively delete the apk of hibernate it (byfar the easiest option of all this).

I don't need betterbatterystats, I have battery Battery Historian, check the screenshots, It's clearly the search bar, on my other phone It isn't shown as a top app.
Also I went in the system folder /apps and there was no googlesearchbar, or in any other system apk remover tool, perhaps it was removed by another app, but it's still for some reason running.

Your 3rd image shows googlequicksearchbox had 370ms (milliseconds) of wakelocks over a 9hr period. I really doubt that is your issue.
If it is your top app, then it is probably because of Google Now launcher listening for OK Google spoken keyword.
I seriously doubt that is your battery drain problem as almost 90% of people probably have OK Google turned on and are using Google Now launcher and only a very few have serious battery drain.
BTW wakelocks aren't the issue usually. In the past it has been "partial wakelocks" which means an app locked the device from sleeping, but never released the lock, so the device never goes to full sleep. If you see some app with partial wakelocks or if you see some app with hours of regular wakelocks then that might be an issue. Minutes or microseconds of wakelocks are inconsequential.
I suggest you flash factory image and install your battery tester only. Turn off wifi, bluetooth, nfc, cell radio. Test the drain overnight. That is a baseline for the minimum drain your device can have. Then enable what wireless stuff you normally have turned on. See what that drain is. Then start installing apps and see what that drain is.
If you have reasonable/expected battery drain with stock and everything turned off, then it is just a process of elimination to see what is causing your battery drain.
If you can't get reasonable/expected battery drain with stock and everything turned off, then you probably have a bad battery.
For the record, my overnight battery drain with everything turned off is 0-1% With wifi turned on about 1-2%. With wifi+cell about 2-3%.
IMO the biggest drains for standby are wifi and/or cell signal related. Either bad signals or apps sending data in background or apps that are polling all the time.

Factory reset didn't do anything a few days ago, the results were exactly the same that was when my phone wasn't rooted, so I guess I should return the phone, and get a new one?

What is your battery drain per hour with nothing installed and all wireless turned off and everything stock?
I'd only return it if that is significantly more than 0-.2% or 1% every 5 hours.
Otherwise it is something you have installed or something to do with the signal and how it interacts with your phone.
Once you start installing stuff or turning on wireless (wifi/bt/cell) then it is no longer purely about the battery and there are more factors that need to be isolated independently.
You really need to establish a baseline to see what the minimum battery drain is. Then you can determine if the battery is the problem or something else.
If you just install everything and turn everything on, there are too many moving parts.

Okay, I now have android N, and my battery life seems to be better, I will leave mobile data off. I will see tomorrow if my battery life has changed.
Do you think I should use Adaptive brightness for more battery life?

Which battery life was the one you think you have a problem with, standby or in use? IMO for in use battery time this phone is about average. Your title of "wakelock" made it seem like you were concerned about standby battery time as it doesn't matter if there is a wakelock if the device is already turned on and in active use.
When turned on, the screen is probably the number one thing eating power, so adaptive brightness could help, but if you are in a bright area, it might be worse than if you fixed the brightness below max.
Even if you have adaptive brightness turned on, the slider scale still is useful as you give the adaptive brigthness mechanism some idea what level of brightness you feel comfortable when the mechanism detects dark, med, bright situations.
One of the worse things for eating power is for the cell radio to be turned on but have no signal, like inside office building or just a bad signal area in general. The reason is the cell radio is power efficient once it establishes signal, but when it is searching for (or loses) signal it uses a lot of power.
If you are doing a lot of disk activity like taking video or hdr pictures, it would probably help to have your userdata unencrypted as this device does software (kernel) encryption and doesn't use the fast/more power efficient co-processor.

Standby is the problem, on screen times are good enough.
Anyway, I don't even know what to do at this point. Android N didn't help enough (cell data is off), I guess I can flash Android 6.0 again and then try to fix it using apps...
What do you suggest I should do, I'm out of ideas at this point.

What is the power drain over a couple of hours with *no apps installed* completely stock, and wifi/cell turned off? What is the change when wifi is turned on?

Have you set "WiFi on during sleep" to "Never"? in the Advanced WiFi settings?
In the original release, there was a bug where WiFi would stay on even if you had set it to "Never" draining battery in standby.
Somewhere between MDA89E and MHC19Q they fixed it and WiFi will go to deep sleep after being in standby for a while, but they introduced another (or exposed existing) bug where WiFi will not resume after coming out of sleep, unless you cycle WiFi off/on. So you're standby battery should be better with this setting, but it'll be a little more annoying when turning on your device.
