Battery Drain after OTA Froyo

I have no idea how to solve it. I have charged my Desire to 100% and after 3 hours I have only 20% left. I have not been using it much. Before upgrade it took about 24h to be only 20% left... Moreover the phone is hot when I touch it. How to solve it...?

I'm having the same issue!
It seems that the phone does not go to sleep (up time same as awake time)
Any help is appreciated as my phone dies within hours

Mine has done the exact same thing... With in approx 3 hours it had gone from 100% down to 50%, in the same normal usage in 2.1, it would of been lucky to drop 15% if that!!!

Mine dropped from 45% when i went to sleep, to 0 this morning!!

I cannot reproduce this, my battery life is a little better than with Eclair. However, I'd recommend downloading Android System Info from market. In the CPU Panel, you have the statistics of CPU clocking, it should give you heads up concerning a phone not going to sleep.
As for reference: my phone's CPU runs at 250 MHz 85% of the time, 1 GHz for like 10% and the rest is somewhere in between.
If you find anything, you should consider downloading Auto Task Manager as well and try killing anything unnecessary. It is not recommended to be using a Task Manager, but it might help in this case. Good luck!

Wich one?
There are 2 with same name. Google's and an other one

Did you all restart after reboot? And did you flash the latest radio?
I flashed to froyo 7 hrs ago, played an hour with it to see the new features and went to bed and woke up still 80% of battery (after mentioned 7hrs, 6 of which my phone and i were sleeping )

Seems to be 245 mhz 50% of the time and 1ghz around 40% of the time, the problem is that I can see that my phone isn't going to sleep according to the battery info

The new radio is already flashed with froyo, isnt it?
And how do you flash a radio without rooting?

Have you tried a factory reset aka hard reset? It could also be some app that keeps the phone awake.

The one from ElectricSheep. The other one is probably not from Google, but from Googe. I'd also recommend looking at battery draining apps in the settings (certain bad live wallpapers can harm battery).
As said before, if you aren't using your phone all time and CPU clock at 250 MHz is less than 80% of the time, something is seriously wrong.

I have the same issue..
After froyo update, the battery lasts only a few hours not even using the phone much. If i put in flight mode the battery not discharge ..
I think it's a problem with radio and not of applications. I already tried hard reset..
Moreover, the phone become very hot..
I hope the htc resolve the problem. I'm in holiday
excuse me for my english

I think HTC did good work here, but I'm sad to hear other people are having issues. Anyhow, I don't think our impression of better battery life is purely due to real improvements, but also because they fixed the battery icon (like Apple did with the signal, but in the other direction...).
Prior to FroYo, my battery icon would look like "50%" when there would still be like 75% power, "90%" would look like 75% and so on. I noticed that when I tried several battery widgets. You know, it's all psychological

I had 55% yesterday night and at the morning i had 49%
idk if its bad or good

Found the problem!!! It was an LED widget stopping my phone from going to sleep, if you have it make sure to get rid of it ASAP!!!
Cheers guys!!

Epic 4g Touch gets extemely hot and battery drains.

I have had this phone going on a month now I would say this problem started about a week ago. The phone (not on the charger) just gets hot and the battery life dips tremendously. (The phone is stock unrooted) I used to be able to get at least 14 hours out of the phone with normal use and 3g on, now i get about 7 hours before i have to plug it up again. The phone can be in my pocket idle and I can feel it heating up, I have never had a device do this I am at a loss right now because the main reason I sold my evo was because of the rave reviews of the phones battery life and all of a sudden that is just gone. I tried searching the forum before posting and found nothing with regards to this problem, If there is another thread like this I do apologize it was simply overlooked.
Any suggestions??? Thanks in Advance.

Could just be a Los, try sending a text or making a phone call the next time it happens...
Usually when I have a ghost Los, my phone will heat up and the battery drops. If you can't send a text, go to your task manager and go to the RAM tab and clear memory. That usually helps, but if it doesn't work, just reboot.

Usually when you have this problem, for me it's always been a program pegging the CPU usage. download system panel to see what's up

Thanks I will give both a try.... The los happens but its rare. I'm thinking of resetting the phone or returning it.
Sent from my SPH-D710 using XDA App

I've had it happen to me once, I woke up one morning and it was hot and battery drained. I noticed it had the LOS circle up top so I attributed it to that..........It's only happen once thus far.

It's not LOS I have service I can call and send texts but the phone just gets hot as he'll and battery life gets destroyed. The thing is this started about a week ago and I have not installed anything new on the phone it just started doing this on it's own.

I would not say my phone gets "hot" but noticeably warmer especially when playing some games. To help with the battery drain I have underclocked and undervolted -25.

The Facebook app didn't seem to like my phone very much. After downloading it and going to bed I woke up with a hot phone. Uninstalled soon after and works fine now =]

I started to have this problem after flashing "Rogue" kernel with CWM

It was Fancy Widget (HTC style clock) I don't know why the conflict started in the past week because I've had fancy Widget since the day I got the phone. Thanks for the help guys really appreciated.

Greetings All!
This happened to me once. While phone was in pocket battery life nosedived and temperature skyrocketed. Wasn't LoS. Looked at running apps/services and saw that AP Mobile was running out of control. Which surprised me since I wasn't using the widget. So I froze it and the problem has not reoccurred. It was probably just a fluke but since I wasn't using it anyway it seemed like a no-brainer to hide it.
Cheers, Henri

I had this issue once and found that it was the enhanced email app. Installed and good to go.

Happened to me for the first time yesterday. I was at 77% and my phone froze. It was extremely hot so I pulled the battery and rebooted. It cooled down but now my battery was at 20%.

i have the same problem use to get excellent battery life then all of a sudden phone last 7 hours i noticed on the status that the up time was 100%. it seems like it doesn't sleep anymore.please help

Something that I have noticed is that every time I pull the battery for this problem when I restart the phone the keyboard is reverting from the Smart Keyboard Pro back to the standard Samsung keyboard. Is anyone else seeing this? Could this be related?

It has to be an app that's killing the cpu look on the first page under my original post Hyabusa1300 (thanks) gave me the advice that worked. Figure out which app is causing the issue and uninstall it.

Almost always a hot phone means it is doing something in the background. Defiantly check battery stats and see what is running

Battery usage question

Hey guys, I am an iPhone convert and using HTC one x for nearly two weeks now. I have rooted and installed leedroid Rom and its much better than HTC stock. So the question is u an attaching a screenshot of ny battery. Is this battery usage kind of good or can I improve it. I don't use my phone for calls much so that's why very low usage on calls.
Would really appreciate some feedback.

It is pretty good,you can try to download Easy Battery Saver and Easy Task Killer from the playstore.Also (this helped me verry much) you can download the CoreControl app from the xda forum:
http://forum.xda-developers.com/showthread.php?t=1652136
You can set it to 2 cores,it will run perfect,the phone won't heat up anymore if you play games and also saves you'r battery life.

Task killers are pretty useless, android is good at memory management. When you kill the task that android hadn't done already it will be restarted right after by android then killed again by the app thus making an endless loop of killing and restarting processes wasting more battery.
And anything these "battery saver" apps do you can do your self, turning off WiFi ect. Thus removing the need of the app and saving more battery.
@op you really need to post a screen on time as well but yes that seems about normal

HTC one x battery life

Hi I've just recently decided to swap my xperia ray for a second hand HTC one x and unfortunately the battery life is horrid, under 4 hours and the battery is below half. 3g is on 24/7 and I didn't browse the internet for even a second , only text and call and I can't believe it, seriously considering taking this back unless somebody can convince me otherwise. All I use is the internet and calls and texts, and if it can't even handle those , then how am I going to be able to use the internet ..

are u using a custom rom ...? if not then say which base it is...3.14 oder 2.17 ...

You might try searching the forum, there are LOTs of battery related threads.
Install BetterBatteryStats (search here for it and how to use it), and check wakelocks and partial wakelocks, should tell you what is preventing the phone from entering deep sleep.

i like the battery life of my phone very much but also think, when you are using a custom rom, the rom and the kernel need to settle and i think, this take a time.. try one and give it 1-2 days, until you see the real battery draining

Came from Xperia arc myself, but wasn't expecting tremendous battery life, tbh. That said, there's virtually no drain in screen off on any stock based rom, so it evens out. Haven't tried aokp, cm10 or miui due to the pretty horrific battery life on the arc with them.

mine hox have nearly 1 year, but no better or worse battery performance. max 1 day :crying:

the battery life of the htc one x is an enigma to me (no other word can do justice to how much confusion it's causing)....I understand everyone uses their phone differently but the battery life shouldn't be all over the place as it is. My battery is lasting between 24 and 48 hours regularly with normal use i.e. normal everyday use on my one x, calls texts, camera, finding a place on maps while lost etc etc
screenshots attached.
I understand a lot of the problems are being caused by the phone not going into deep sleep. One of the ones I pinned it down to was if you go into Maps and check the location settings through there...i've turned them all off (and i still get correct google now information).
If someone wants to try that and then let us know what its like then that'd help everyone.

well not quite sure what you're doing with your phone - in that image, your mobile signal is only on for about half of the total time? did you have it in airplane mode or something?
my battery is pretty terrible - actually shocking the past few days. I can't even get through a full work day without it being down to <30%, which is only 9 hours or so. I've had power saver turned on all the time, too. I use it a bit for texts during the day and that's about it - no heavy data use. so I have no idea what's sapping it so heavily. it's quite bizarre. even if I try to micro-manage my data by turning it on only when I need it, I still get down to 40%.
this is on a stock ROM by the way. considering changing to a lighter weight custom ROM to see if that helps, as this is just ridiculous!

actuallyi just glanced at ur screen shot and for u it might be the mobile radio. It seems like ur signal is spotty for most of the time. this drains battery like no other when trying to find a good signal this goes with wifi too

HOX's battery live was terrible at first. (ICS & Old kernel)
Now it seems that it has reached its max capability. It saves the day, but it would be great, if the battery had been 2100 mah. :angel:

How much was your screen on time tho? I could just leave my phone doing nothing and have over 1day battery.
@op you could try the battery calibration. Charge phone till green light, once fully charged unplug and switch off the phone and charge again till green light now switch on and use phone.
You should now have better battery.

Update kills battery life and adds lots of heat

Kitkat update killed battery life and makes the tablet extremely hot near the camera on the back. What gives?
Sent from my SM-P600 using XDA Premium HD app

I don't have a solution but the same problem. I'm fine with it getting warm but it's getting really hot! It's great that we have kitkat but it's not all that stable yet.
Restarting seems to help temporarily. Feels like something gets stuck and then makes the CPU run extra stuff but I don't see anything with my wakelock analyzing apps...
When it is in "battery-eating-mode" even browsing or watching a video makes it run hot!

Generally it indicates that a file or service has become stuck, or hung. For me it's common for the Samsung.index.service to get stuck indexing a file and sometimes lasts 3 days before it's resolved.
You should use some kind of monitor to see whats causing it.
Gsam battery monitor does a good job of showing rogue apps, and battery and heat.
Also a CPU monitor is included in the debug/developer which can also show the culprit.

I quite upset about this now. I reset my device and still have the same problem. My tablet used to be excellent and had great battery life. Now Kitkat Haase it basically useless because the battery drains so fast.
Sent from my SM-P600 using XDA Premium HD app

Indexservice uses 30 percent of my battery. I read that happens if you have lots of pdfs on an external SD card, but for me that is the whole point of this device. If I just wanted to play games, watch videos and surf the Web I would've gotten an ipad. Really dissapointed with Samsung here. Did they not test the device before they released the update? Or do they clock out of their jobs and go home and use ipads?
Sent from my SM-P600 using XDA Premium HD app

Yeah the indexservice did the exact same to mine, Samsung were no help. Happened even when I put PDF's on internal storage.
I had no other choice but to root it and freeze the service with titanium backup, I really didn't want to, but I was left with no other choice.
As I had gone that far I also froze a bunch of other Samsung apps/services - I am so glad I did, the tab absolutely flys along now - feels like a different machine.
Root it, you won't be disappointed

Sony released a statement suggesting disabling the Google backup functions to improve battery life with kitkat Roms. If you don't need those maybe you wanna try that as well.
Settings/general/accounts and save&backup

It will likely fix itself after a few days. It happens on mine every few months for a day or two. Then it settles down and works normally. Same on all Samsung devices.
Has nothing to do with KitKat.
Sent from my SM-P600

I did some testing with an app to check cpu frequency and here's what I found:
Sometimes the tablet goes into "fury mode". Which means that as soon as there is any task for the cpu however small it may be it drives all cores to max 1.9ghz and full speed. Which means even while I'm browsing or watching a video the tablet runs about as hot as when playing an intense 3D game. And with equally bad battery life.
Really bad performance/efficiency handling. Like now I've been browsing(chrome) for 30 min and it ate 15% battery life and it's extremely hot on the back where the cpu is. There aren't any special processes running I've checked with watchtower. Cpu load is not that high but frequency has been constant 1.9ghz max speed on all cores... need custom Kernel PLZ.
I have to say though this is not always the case. Sometimes after a restart or when it was laying around for a while this fury mode doesn't happen.

just rooted and froze indexiservice using titanium backup...hopefully this will help

Ok looks like everything is good now.
Rooted and used titanium backup to freeze all the stupid stuff that was causing the device to get super hot
