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 .

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.

Battery Drain Advice

Hi All
Disclaimer: I'm new to the forum so apologies if this is in the wrong discussion area etc!
I got my Galaxy S9 on Friday 9th, prior to that I had an LG G5 which is now gone. In the last few months of using my LG G5 the battery life was questionable - the phone would get hot (sometimes without even using it a lot) and the battery would drain by 30% an hour. I noticed, but didn't test fully, that Google Play Music seemed to really cane the battery and phone - i.e. was getting hot and draining quickly. As an example, I'd leave home at 7am taking it off charge at the last minute (100%) and get to my office at 9am and it'll be at 50% and very warm. Prior to that (can't exactly pinpoint when the drain started to really kick in) it would only drop to 85% - much more acceptable.
The G5 has a replaceable battery - 2800 if I recall . So I threw down £50 on an official LG site for a new slab of Lithium - slight improvement, but still terrible and warm. 55% instead of 50%.
"Right - time for a new phone" as I assumed that 2 years of app updates meant the CPU was lagging. Bagged a Galaxy S9 - today was my first commute into the office. Started on 100%, arrived at 55% with a 3000 battery! And it got super warm like the G5.
Most of that time I used Google Play Music, which according to AccuBattery the discharge speed was "33% per hour". Second was Google Chrome at 30% per hour (though I didn't use it much at all on the journey).
My question is - what logs can I check, or apps I can use, or something to find out what's going on? I need to test a few things of course to pinpoint the issue. If it helps - I restored from my G5 when I setup my S9.

seems like you might have have some options enabled in Google Play Music / chrome - that is keeping the phone awake
generally when you switch phones they apps and their settings get transferred automatically now - worth maybe uninstalling them for a day and see if you're still experiencing this issue
other than that it could be that your commute involves travelling thru areas of no signal where the phone keeps trying to find a signal - that can drain battery a lot

Thanks - I'll try that next time. Might also try a factory reset but not restore from the LG G5 backup to see what happens then.

how bright is your display? do you leave it on all your commute?
Got your wifi enabled which hunts for a signal even though you aren't using wifi? try turning it off. Same with location setting.

And how strong a signal do you have on your commute. Streaming lots of data on a really weak signal will kill battery, too.

Go into settings and see whats draining your battery.

Battery Drain Issue of S9 - Resolved
:laugh:Hi All,
I could resolve the Battery drain issue but not touching any other setting of the new phone by just disabling the backend data usage of all application expect few like Edge screen, Gmail, Flipboard etc... Now the android system power usage is back to 4-5%. Previously it was 21%-25%. So issue resolved. Need to find out the way to inform this to Samsung so they can identify which app is consuming full battery power.

Hi, i'm facing ridiculous drains too and factory resetting hasn't seemed to help. I'm trying your resolution, but I don't entirely understand you. Could you kindly guide step by step? also, if you mean going to optimise battery usage, when i go there and select the 'apps not optimized' all the apps there are greyed out therefore not allowing me to select them.

IMS wake lock drain

Hi, I recently got my S9 but however lately I've been getting idle drain. With mobile data off, I lose about 2% every 2 hours and with mobile data on, I lose 4% every 2 hours. I have GSam installed and used ADB to give it permission for battery stats. Below are screenshots
http://imgur.com/gallery/5c4Q4j4
It seems to be from IMS service. I read that it can be from either WiFi calling or volte. I do not want to turn off either. Had anyone else experienced this? I still have good battery but this idle drain isn't normal. I haven't left my phone overnight so I guess I might try that tonight and see how much it drains

Hi there,
I am re-opening this old thread since I am facing the exact same behaviour with my new S10+. Due to IMS wakelocks, my battery drains 30-40% overnight (while I'm sleeping for 7 hours). If I put my phone in flight mode, it loses 1% overnight. Did you manage to find a solution afterall? I really hate having to put my phone in flight mode every night. Thanks in advance :highfive:

Did you ever find a solution to this? Experiencing same problem now ...

Hi ... did any of the posters above find a solution to this issue ?
I am stuck at exactly the same problem: The phone (S9, stock-rom) drains approx 20% over night, doing nothing. Reason (according to GSam Battery Monitor) is the high power consumption of Apps > Android-System > 48 mins (264 count) wakelocks caused by ImsService.
If you look at the picture of batter usage in Gsam you clearly see, the phone stays active all night and barely sleeps/dozes :-(
What I already tried, without any effects:
- clearing cache of all "IMS*" Services in App Manager
- wiping cache partition
- disabling AOD (Always On Display) and VoLTE Telephony
- removing and re-adding google account
I am a little clueless and would like to avoid a factory reset as especially all those nasty "push-tan applications" will most likely need a re-authorization :-(
I'd heavily appreciate any hint.

After a long journey it seems that I found a solution: At least on Android 10 there seems to be a bug in google location services. If you disabled location history, the API requests are still made but get stuck each time (every 60 sec.) and keep the phone awake instead of returning to sleep.
The "bitter" solution was to turn on Google Location history again ... and suddenly the drain ends, as the detection and transmission of the location is ways faster, than letting the die in a timeout ...

Horrible Battery life on Pixel 2 XL (Pie) (6%/H Drain)

I'm a really light user. I lost a little less than 2% every hour. Basically I use it as a purely communication device. Mostly check facebook messenger, my emails, and occasionally, browse facebook, reddit, 9gag or watch a short youtube video. I stay up about 16 hours on average and at the end of the day, I was regularly around 80%. If I left the phone unplugged overnight while I slept, I only lose about 6% over 8 hours. I was really happy with the battery life. I could very easily see 3 full days out of my phone off a single charge. This was before the Pie update. I tried both the Beta and the Stable once it released, and my battery life has suffered severely. I'm losing 6% every hour, even with the screen off the entire time. At the end of the day, my phone is in the red and has already turned on power saving mode. Android Pie has killed my Pixel 2 XL's battery. I gave it 2 weeks to "learn" my usage habits, but ultimately, I factory reset and even went back to 8.1, but I still suffer from battery issues. Battery usage gives no hint to the culprit. My phone has been unplugged for 7 hours, with 45 minutes of screen on time, and at 54% remaining battery life. Screen On time is the highest battery drain according to the system battery stats. I didn't have this issue until I installed Android Pie Stable.
I have no idea what could be going on, but could really use some help with this.
TL;DR: From 2% to 6% per hour battery drain on Pie. Reverted to Oreo and FR but still an issue. Advice?

Did you check if the WiFi scanning is turned ON? Settings --> Location --> Scanning
I feel its the only issue, nothing should drain your P2XL crazy if apps remaining constant factory reset.
-- personal experience.

I also use it very similarly to you and easily get 2 days with a single charge on Pie. During night my device drains 1 or 2 % only (wi-fi, bluetooth and 4g on), but I have wi-fi scanning off. Google location services are on (including Location Accuracy on). "At a Glance" is turned off but still using stock Pixel Launcher. No hacks/mods installed.

Same except I have at a glance enabled. I disable it 6 hours ago to test and didn't affect battery drain at all. Still losing 6% every hour. Location and scanning settings default except connect to open WiFi is enabled. Right now testing if connect to open WiFi and Bluetooth WiFi location improvement affecting battery drain.

Testing that now. Will report in a day. Heading to bed now. Gn

Does the phone charge all the way to 100%? Does the phone ever turn off by itself when low on battery ~10%? Install and run Accubattery. After a few charging cycles you will get a very close approximation of your battery's remaining capacity as compared with new in mAh. Battery capacity will be located under the health tab. The more charge cycles you monitor, the more accurate it gets, but it will zero in on a number pretty quickly after the first 2-3 charges. Could be the battery... stranger things have happened. This also assumes the user has fully wiped the phone several times going between DP's, Pie and reverting to Oreo.

Does the phone charge all the way to 100%?
- Yes
Does the phone ever turn off by itself when low on battery ~10%?
- Honestly, I don't know. I never let my battery get that low.

Video of battery stats and settings.

I changed some settings and now I'm getting 17mAh drain. Fixed.

The biggest battery sucker for me was having Auto-connect to open wifi enabled and fixing stuck sync tasks. It was preventing my phone from sleeping.

Great to know you were able to stop the draining, I think it might be of great help to other P2XL owners to know what were the settings you changed that fixed the issue.

What settings did you change?

I am having the same issue. I would be interested in hearing your changes as well. Thank you

Download and install Accubattery to monitor your mAh usage. Make sure you check your deep sleep percentage. By the sound of things, your phone is running hot when idle, so it's not sleeping like it should be. You can install Wakelock Detector Lite to see which apps are keeping your phone awake. Once you find out what apps are draining your battery, use the System battery manager in Settings to restrict battery usage for those apps. If that doesn't help, then uninstall the app (unless it is necessary to you). If an app isn't keeping your phone awake, then it may be your system settings. Turn off location scanning for wifi and bluetooth (in the GPS section). Turn off Wifi auto-connect to open wifi. Where I live I have pretty weak cellular connection. I opted to disable Mobile data always active in developer options (Go to about phone, and tap the build number 7 times, then enter your device password). While you are here, you can check Running services in developer options and see what you have running. Also, make sure your accounts aren't stuck trying to sync. If they are, cancel the sync and restart it. Depending on how far you are backlogged, this can take a while. If the sync still gets stuck, try removing and re-adding the account that is getting stuck.
After I restricted/uninstalled the misbehaving applications and tuned the device settings, I'm getting great standby time on my Pixel 2 XL. If I close all my apps before putting the phone back in my pocket, according to accubattery, I'm losing 15mA/h or about 0.4%/h. If I charged my phone to 100%, then unplugged it without using it at all, it would take 10 days for the battery to run out. It's pretty good. As someone who primarily uses their phone as a communication device and research tool, I'm a pretty lightweight user.

+1 What settings did you change?

Yes, please, don't keep us in suspense!
Just got a used one so trying to learn all about getting optimum performance.

Battery drain too fast screen off

Hi guys i have my pixel 3xl and my battery is drain too fast when i dont use it in night fo exemple a left him 100% after 6hours i found him 70%
I chek if thers is an app in background and nothing i Factory reset it 3 times and same thing

Let it drain down to about 10%, and then check the battery stats to see what is high on the list. I get less than 1% an hour, and have for the longest time. Running Android 11 since beta 3, and now official.

Hi! I got exactly the same thing with my Pixel 3 and got the same issue, it seems like our device cannot deep sleep. Here is my battery usage and wake lock on EXKM (Running latest Kirisakura, screenshot attached)

Also mine, last night it was 100% then this morning, when i checked it, its already at 95%. Also i noticed that my 3xl now is draining too fast, any tips on regarding this to save or extend my battery? Thanks guys

First week(nearly) after factory reset or flashing img your google play services should drain too much battery which is normal as settings are calibrated, usage patterns adjusted, small updates installed etc.
Most battery issues are related to some rogue app, bad signal reception(it does not need to be full bar, even selected frequency by carrier or phone) or confused google play services. If it is google play then root needed to find root cause(pun intended )
For my case a full day with 1h+ gaming and whatsapp, phone and other stuff 4hrs sot and generally less than %20 percent battery at evening to start charging. You should be happy if you are near this values.

Hi! Thanks for the insight, I'll try to wait until a week and going to post an update here! Just curious because I can't find any information about the kernel wake lock that constantly occurring on my new phone
Edit 1:
So after a few days of searching, I found out the one who cause the deep sleep issue was my modified settings for the Entropy (I modify it via EXKM), after I set it back to default the Deep Sleep issue completely gone and I can stay 0.2 ~ 0.3%/hr when the phone is Deep Sleeping
I hope my issue can help you, and try to reflash it via fastboot with the latest (Android 10 / Android 11) pixel image just to make sure that there is no corrupted data
