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.

my battery drains like a bugatti veyron doing 252mph constantly
so what would you advise . is the kernal i have now the best or should i change .. i dont want to reall lose much performance on what i have now but would like the battery to maybe improve if possible ...
from full charge taking plug out searching market for 2 mins the battery drains 5-8% in matter of mins
and i have only had the phone a week
With that kind of drains the problems the kernel won't change that much. There is probably a app that causes the battery drain so looking in to that will have more effect. Also the brightness/screen on is the biggest drain and kernel won't do much about that.
You said that you have the phone a week, the battery needs some time to reach it's full potential and you probably use the phone a lot because it's new. So use the phone normally for another week, after that week let the phone drain until it shuts itself off, leaf it off and charge it till it's full. (there is a different calibration method but this always worked for me)
What do you have now? Stock or rooted?

First of all, I would assume that you don't use the phone non-stop (it would be justified to lose power in a few hours if you're on it non-stop).
I recently had issues with power consumption as well. What I did was:
1) check the built in battery monitor: menu-settings-about phone-battery-battery use. The bad thing about this monitor is that it does not differentiate well the apps consuming power, but you can still see if there's something wrong, as the most consumption should come normally from the screen and voice calls. For me, the most consumption was made by com.htc.bg, which, if I let the monitor on for a few seconds, would transform in the calendar app. Weird stuff. I unchecked the calednar auto sync from menu-settings-accounts and sync. It may have slowed the power loss down, but not significantly. I noticed a significant loss of battery by WiFi. I realized, I needed more information so:
2) I installed an app called 'Power Tutor'. What it does is, it calculates which apps consumes power, and it shows you in percentages. After install, you need to start the 'power profiler'. It will appear in your notification bar. If you let it run, after a few hours, you can see in "view application power usage" who is using power. That's how I discovered that my winamp app was really off the charts using power like crazy. So I went in the winamp settings, and I unchecked some options that could have determined this power consumption, like wireless sync, automatic mount as USB drive, etc. There was actually an option that was overriding the wifi power management, stating that the wifi does not stop after 180 seconds of standby. Basically, if you have wifi on, and you stop using the phone for 3 minutes, the phone automatically turns off the wifi. This was not happening any more, due to winamp. So I unchecked all those options, and voila. It worked, I have now normal battery life.
Good luck!
be aware of a couple of things
1. battery drain for the 1st few weeks are high because of a couple of factors, the battery "learns" and gets conditioned over a period of time (doesnt use the old 16hr charge process). its a new device for you so its a novelty, you probably mess about with it with the screen on more than you think.
2. there is a configuration within HTC's builds and in the memory chip of the battery to stop over charging. the device will charge to 100 and then slowly deplete to 90% while still saying full on the phone. as soon as you disconnect it recalibrates to the correct value which is anywhere between 90% and 100% depending at which part of the cycle you catch it
Some other tips to increase battery life, from a friend of mine in the Romanian forum:
1) use the app watchdog, it will warn you when an app is using too much of the processor and will ask you if you want to close it.
2) juice defender with the paid add-on 'ultimate juice' - with the correct settings... it's amazing.
3) Dial *#*#4636#*#* - phone information-network type: select gsm auto prl. The phone will stay on 3G when it has good signal, and switch to 2G when it doesnt, saving battery
4) Change the wallpaper to a static one, not a live one.
5) Go to menu-settings-accounts and sync and increase sync intervals for weather, news, or even set them to sync manually when you choose.
i will try and answer everything at once ..
ok my screen is on 13% brightness
i hardly ever use my phone , the only real use was to root , s-off, put ROM ETC ON
I reply to about 50 texts ish per day and search the market for literally 1-2 mins to see what new apps are in
i dont play games or anything
the thing the battery uses most is the screen and as i say i have it on monochrome theme with 13% brightness, there is nothing synced , i check automatically for email etc .. actually beautiful widgets is set to auto update every 4 hours
i never use wifi as i have a 3gb download/data usage, i dont use gps ...well i do but i have had no need to .. thats about all i can tell ya
rastaman the pt2 is a bit weird it should stay at 100 if just taken out of charge
I calibrated the battery and that made no difference.

Hello,I am using Zenfone 2 16GB, 4GB ram . My battery life is bad every 3 minute %1 drain fastly ...
I can see screen time maximum 4 hour or maybe a little more for 4 hour.Screen Light %0 wifi is closed and everything is closed no working program no working bluetooth or nfc etc..I tried everthing for better battery life but ı cant solve this problem ı bought my phone one mounth ago and ı see everyday android is is using %45-50 battery.I never opened auto screen lighter or 4g or ntc. But drain,fastly every 3 minute %1 drain.my firmware is 2.20.40.58 and how can solve this problem can you help me please
To help improve battery life
1. Please ensure to turn off 'Wifi Scanning always available.'
2. Please also see the following information showing 8 ways to extend the ZenFone 2 battery Life. http://www.asus.com/us/support/FAQ/1012981/
3. If still no improvement then recommend performing a hardware reset including cache wipe partition and try steps 1 & 3 again. http://www.asus.com/us/support/FAQ/1011956/

None of those ASUS official 8 ways do solve the root cause of the battery drain issue.
So far I find most interesting way that may really double your battery life is to activate the "Intel Deep Sleep Mode"
Please check at the link (sorry too new to post a link)
-quote Post on 2015/8/11 01:16 | View KLChi's posts -
Hi
I still dare to activate my Zenfone2 deep sleep mode following the process.
Guess what happened? I have no problem with my proximity sensor nor any issue with ZenMotion after 1 week tests.
And the battery saving effect of this deep sleep mode is working like a champ.
I have not yet calculated scientifically but the deep sleep mode at least *doubled* my battery life, which means before activating deep sleep mode I need to recharge every day of even 1/2 day. Now my Zenfone2 could work without charging for more than 1 day or even 2 days under normal use.
Now I have removed all apps related to battery saving like amplify, greenify, battery doctors, etc.
and I don't even need to close any app in startup management and the deep sleep still works and extend my battery life up to 2 days recharging cycle under my normal usage.
Although I find a side(not bad) effect so far is that the file transfer will be "deep slept" (i.e. backup progress stopped at the % where your screen turns off) and it seems the moving activity in the background is deactivated when screen off. But this is not a issue to me as I expect all apps and activities that out of my focus should not keep draining my battery. I can achieve this by stopping unkown/unecessary wakelocks through "xplosed + amplify" but I don't need them anymore as deep sleep mode seems does the same for me.
One thing really does matter to me is that will all notification still works? My test so far shows that by activating the deep sleep mode will not disable any wifi nor 4G signal nor any notification that the apps should normally give you alarms/warnings, especially wake up alarms.
I'd like to really really thank you for your advise.
I think this "intel deep sleep mode" is really a total soultion to the Zenfone 2 battery drain issue and worth a try, at least for me so far.
I don't know if this process also may apply to non-intel cpu android phones which also have the andorid os battery draining bugs.

can you tell me the steps to enable deep spleep mode?
I am a noob bro :angel: but the following tweaks will certainly help u.
I use auto start manager to manage almost all except a few apps like whatsapp and truecaller etc.
Disable wifi scanning and wifi network notification in wifi advanced settings. Our phone's brightness is too much even on the lowest setting so keep it around 25-30% for lower battery drain from display.
Watch out for wakelocks, read the battery graph. I prevented truecaller and playstore from waking up device.
Turn off gps when not using.
Disable asus built in bloatware and certain google apps that u don't use e.g. i dont use google plus, talkback, hangouts and even chrome since these run in background and drain battery.
Google app is also a big culprit. I personally don't use google app and disabling it will make a big difference.
Then use data usage in mobile manager for further tweaks. Avoid 4g/3g when idle.
Mine is a 2gb z00a and i get a decent backup of around 1.5 days with normal usage with calling whatsapp browsing. Intel processor is a battery vamp and this fact can't be changed.
And not to forget after every ota update perform a cache wipe to get rid of conflicting data from previous firmware.
And this intel deep sleep mode is new to me..will also try it.

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.

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.
I recently bought this phone, I updated everything system, apps......the camera keeps running the background, even when I have closed the app.....
Problems does go away if I clear data of camera app...but I don't want to do this everytime.......I bought the same phone for my mum, and same thing is happening there too, on top of that in her phone chrome is consuming a lot of battery even when the phone is idle...... please help me out
Also I did try that restrict background activity but that option did nothing and the time on "while in background" kept on increasing
P.S location was off.
Never happened this problem to my European LG G7 Thinq (LMG710EM).
Anyway you have to turn off "background activity flag" to stop background activities of any app (do it for each app).
But consider also that the 7% of battery may be consumed just in that 11 minutes.
Shooting photo consumes a lot of battery...
After a week I have figured that you need to compromise on 2 features to get a good battery life ......1st obvious one was always on display, after disabling that, battery life increased a lot, but my idle battery drain was still 1-2 % per hour with wifi turned off.......2nd I disabled the double tap to wake (knock on) and hallelujah! Now on idle it barely drains 1-2% overnight.....
This is a great phone but lacks in the battery department...I mean, I don't mind disabling aod but double tap to wake is a great feature to have...too bad it drains the battery like hell
