Android System Using 91% of battery! - Desire General

On my Desire when I went to check what was using my battery the most it showed the Android system is using 91% of it...anyway to decrease it? Or whats causing it to be so high? I've got no apps running in the background or anything other than weather and stuff. I've got everything to be sync manually other than the weather.

Your battery is going to get used no matter what. Most of the time your phone isn't doing anything so it stands to reason that the system sitting idle will use the most battery power. If you played a video on repeat for a couple of hours , that would use up the battery instead...

perhaps you dont understand, at that particular point out of 100% battery usage 91% goes to the system which sounds right to me as you said all other programs are not running.... another example its just like having a fan , a computer and a microwave... if he pc was off and the fan was running....at the point 100% of electricity usage would go to the fan but if yoy switch on sometging else..then the % changes...

Thanks everyone1

Wrong!

No because that is why their is a category for cell standby and phone idle....
If you optimise your phone settings, you will get...
15h 28m 23s since unplugged
cell standby 38%
phone idle 37%
android system 12%
Obviously with heavy usage then you'll find that android system is higher, however generally if you spend less time using it and more time that it is on idle then android system will be less than cell standy and phone idle.
P.S: This is with background syncing on every hour.

Wow - great thread necromancy!
If something is dead and buried for 3 months, best to just leave it there!

Bit territorial over the forum much?
Not that it is your business but I just got a Android phone and I wanted to clairfy for people who, like me, had to research how to get the best usage out of the battery.
Maybe stick to the topic of the forum posts rather than telling people what to do?
I think so.
Kindest regards,
Stephen.

That's great info Stephen! My optimus 3d is running at 70+% android system after sitting idle for 6 hours ... and then after 30 mins of internet / Google+/Facebook Its about the same... even display is only at 4% and Idle is low too.
Any suggestions of what system tweaks will improve my battery life!? :-/ I just downloaded System panel in the hope it will help too!

Biggest drain in battery is network usage, so just make your apps sync less often, enable the power control widget and toggle network data on/off when you don't need it.

Screen is the biggest consumer hands down. If your radio fits well with your carrier you would get less than a 1%/hour with some apps syncing. And Google maps somehow is the devil itself in 2.3 if Latitude is enabled.
Nice thread revival btw

Competition: Best Batter life ROM

any chance of mods running such a comp? with 3 way toggle for battery save, gprs and gps?
you can always add the HTC widgets to the home screen that allow you to toggle all the battery draining stuff. And in 2.1, there's a single integrated google widget that does all the same stuff.
It is so intermittent that it would be impossible to get reliable results. I found brilliant battery life with Villain and average on MCR and really terrible on stock HTC. I get three times as long out of my phone now i'm on Villain than I did on the stock firmware.
However, everywhere you hear so many stories of people having poor battery life on custom roms and such varied accounts even on the same rom's that it would be impossible (at the moment) to get some reliable comparrisons.
I dont know u though about 2.1 or 1.5 but the Kimera v.1.5 , which based on android 1.5, has an awesome battery life
yes tried kimera, will try it again when phones re-charged, might have to give villain 4 ago beofre tho. my normal one is ahero tho.
be nice if could be some sort of benchmark for battery usage like there is for speed tho

and that doesn't make you suspicious? there is obviously something wrong...
Easiest solution............
Turn it off! If your that bothered about the battery life buy an old school nokia 3310 put a paygo sim card in your HTC just to play with it.
Have you not noticed that as phones get smarter battery life gets lower?
On a side note i charge my battery whenever possible, carry a usb lead everywhere with me as i can plug it in at home,in the car,in the pub,at work etc
And remember - regardless of which ROM you use, if you use a lot of widgets, programs which run in the background or programs which sync often, you will find that your battery life will be significantly reduced nonetheless.
Often you can use a shortcut to an application instead of a widget and get on-demand functionality instead of an auto-updating and battery-draining widget.
Disabling wifi / mobile data / mail auto-syncing / GPS, as well as decreasing brightness and the time the screen is on while not using your phone, will help for any rom too.
Good luck.

You're suggesting I should be suspicious because my battery is lasting like it should be? Currently:
71% left
Up Time: 2d 20h 47m 59s
66% Cell standby
34% phone idle
I've also been texting and internet & market but nothing heavy.
It just depends on what you do with your phone, I wonder sometimes why people think they should be able to have wifi, gps, bluetooth, and every other feature turned on and expect their phone to last more than a day? Does your laptop last a day? and look at the size of that battery. I know the hardware is stripped down but your phone is now essentially a miniature pc so stop complaining. If you get used to turning off all the features which drain the battery you'll see a marked improvement. If you can't turn them off for any reason then buy a larger capacity battery! There are loads around on ebay and other sites. hxxp://cgi.ebay.co.uk/EXTENDED-3000-MAH-BATTERY-REAR-COVER-FOR-HTC-HERO_W0QQitemZ380174233125QQcmdZViewItemQQptZUK_MobilePhones_MobilePhoneAccessories_MobilePhoneBatteries?hash=item5884266e25

Yes because the battery should not work like that, its a smartphone not a bottom range nokia work phone.
like I have said before no smart-phones battery are meant to last longer than say 2 days max of normal use maybe 5 at a really really really basic/no use

Battery Life

Hi
Had my phone a little over 24 hours and I may have a very poor battery
I have a LIVE screen on the one with the water and the leaves plus, I haven't made or received any calls but I have used it a little for internet and a few text messages
The green bar was on full about 5 hours ago and if I had to guess how long my use has been I would say 30 mins in total of the 5 hours, now my battery is indicating less than half full
Imagine if I was out all day making and receiving calls?
Does this sound normal?
This is normal for the first week or two , the battery is adjusting itself to your needs
Sent from my HTC Desire using XDA App
It's absolutely normal and you'll really notice a difference in about ten days, a couple of weeks the most.
That said, live wallpapers do use more battery. I much prefer a static dark one
adding to that make sure your phones nicely drained before recharging to ensure you get a nice full charge for next time... i took my desire's battery at least 5 days to start having a long term charge
bettery
same here took a week also what really helped me is having advanced task killer and setting it to kill unwanted apps after i lock the screen
i dont think you should use task killer, the apps will end them selves, i used task killer and got alot of force close after and errors etc
however force stopping unwanted applications is also good.

5 H 55M 55S unplugged, hahaha no joke its all 5's
and now my battery is almost dead surely this cant be right
has anyone ever been given a replacement battery for their phone or do they ask for the phone to be returned if this is infact a fault
Battery sucks, phone is power hungry. Get used to it
I've had 2 desires since a week after it was released, i can count on one hand how many times I've got through a day without plugging my phone in.
I get about 2 days on my phone if I don't mess around with it a lot or get many calls. I normally plug it on overnight. Every night.
Nowadays that seems normal for a smartphone. Personally I think the battery life is slightly better than the iPhone 3GS.
Angry Birds means it lasts about 4-5 hours...

It's all down to how your using your phone. If you have a live wallpaper and many widgets and apps that run in the background like running in the notification bar, then yes, your phone will die pretty fast. Also it depends on how much CPU your burning. When I first got my Desire, I was like WTF. This is useless battery life and was starting to play hell. Now it's fine. I can leave it for 2 days easily if I just text or flick through settings. It just depends on what your running.
BTW, no one should have a task killer. It defeats the purpose of Android. You can get a lot of force closes and other things. Just leave them alone and let the OS handle the apps. Android does end the process if it's idle, eventually, but it's not using anything really other than a bit of memory just to keep it going a little.
As GoogleJelly pointed out, it really does depend on what you do with your phone and what's apps/processes are running on it while the device is using battery. Even I found the battery life pretty poor at the beginning...I found it quite annoying having to charge this thing nearly every day.
After some light tweaking, I managed to get the battery life to go over 3 days and I now have no reason to complain about my phone Mind you, I'm not a heavy user....As for background apps, I think i've got about 5/6 apps running at a time...
EDIT: I've attached a screenshot of my battery meter.....
What app are you using to view your battey history?
I also tested task killer when I got my phone. I thought it was fixing battery life, but after bedding the phone in a bit I took it off to see how much difference it would make and I didnt notice any difference at all...

I configured Quick Battery app to go to battery history from my phone settings every time I tap on it. You can view your battery history through:
Settings > About phone > Battery use.
If you want the graph, just tap on the top layer which shows the length of time you've been on battery.
EDIT: This works for Gingerbread based ROMs (it's the standard feature lol)...can't remember this being on Froyo.

This is irrelevant with Li-ion as this is a myth from the ages of NiMh batteries. Your battery will not get ruined if you don't discharge it completely before first charging.

Ah right, cheers for that. Didn't know it was all built in
One of the main reasons why new smartphone owners experience fast battery drain lies in the simple fact that they fill up seven homescreens with widgets that sync over mobile internet every hour or even more often, which really kills the poor juice like a massive gas leak.
After about half a year of use I've reached a stage where I use just 2 screens on my Desire (CM 6.1.1), of which page no2 is a full 4x5 agenda and Page one has just one actively updated widget (home weather).
Combined with restricting network usage of random apps by means of DroidWall and underclocking the processor at certain parameters (eg. battery <50%) the phone lives for 2 days pretty easily, with moderate browsing, music etc included.
But TBH I've really decided that the battery usage is absolutely random because some days it just drains like there's no tomorrow with no apparent reason that I've been able to identify. Carry a spare microUSB wire tbh :/
I read so much myths in this thread concerning Li-Ion batteries.
First of all Li-Ion batteries do have instantly the capacity they are intended for. Even 5 charges won't change that. The only thing which can change over time and charge-cycles is your phone recognizing a new voltage level as "full" (read more: "calibrating htc desire battery") or you playing less with the phone or having power-consuming apps uninstalled.
Also a full first charge is not necessary. This "requirement" are from past days with NiCd or NiMH battery-types.

The calibration during the initial week or so of using the phone arises from phone-side calibration, not the battery itself, which is why deleting battery stats from recovery can at times resolve battery issues :V
Phone didn't last half a day after flashing CM 6.1.1; after a couple of days I charged it to 100%, deleted the stats and voila, it's about as perfect as a terrible smartphone battery can get.

[Q] Battery consumption: I need your help for a comparison

I found a very good program for my Motorola MB525 (Defy) for monitoring the battery draining from the market.
It's name is Batery Monitor Widget and it's free.
With 81% of battery it says only 7 hours and 16 minute left without doing anthing!!! The data is on and Wi-Fi connected to my home network.
Is it normal?? In the night in airplane mode after 9 hours it drain 8%-9% of battery. Again: is it normal???
If you can try this application and report your results...I think there is some application that drain my battery!!
Thanks!
Not really a comparison here, just a little story.
Yesterday i screwed up my Defy playing around with some rom. Nothing terrible, but i had no time to re-flash another rom, i had to go to work. So, i pickep up my old SE xperia x1.
After an entire day, 4-5 calls and several sms, that phone drained less than 10%. Then, last night i put the x1 in stand-by, well, that was a real stand-by, no power consumption at all.
Now i'm back to Defy, 2 hours, 15% drained...
All this just to say android is amazing but terribly hungry of power, even when the screen is off, even when airplane mode is on. I don't need a comparison to know about it
EDIT:
you said your wifi was left on, well android is hungry of data too. Even if you do nothing while wifi is on an amount of data still flows, sometimes i can see several mb downloaded by my Defy in a few hours, but no real usage by me. This also contributes, you should try to turn the wifi off or disable background data when you don't need it.
In standby (3g, sync only calendar and contacts) I have 1-1.5% battery consumption / hour. I think this is normal
With my normal usage i have some 20-40% left at the end of the day... also Ok.
WIFI on & connected will consume a lot of battery so I am not surprised.
BTW I also had an Xperia X1 and the consumption was roughly the same as the Defy... In fact more than 1-2 days on a charge I very rarely had on any of my smartphones with normal usage.

last week I was working in the forest for a few days with no signal at all, so I turned on airplane mode: I remember it going from 45% in the morning to 42% in the late afternoon!
(with everything turned off, just used it occasionally to have an idea of what time it was)

It's ok to be an android fan, i like it too, as i said it is amazing. But, battery life is definitely NOT the strong point. I can compare the two phones now, at this moment. Honestly Defy's battery life is a lot shorter.

what's the other phone you compared?
I really don't have problem with Defy's battery life. As far as my memory serves, all cell phones I ever owned (7~8, all nokia, se, moto) could standby (just standby and don't use at all) for a week or made around 5 hours call. In my case Defy can also standby for a week or allow 5~6 hours usage.
I'm on a 2g network (probably helps alot), as I have wifi at home and at work. I have an exchange email, a gmail, 2 yahoo mails, and a weather app, all allowed to sync at default settings. I don't have facebook or twitter. GPS and bluetooth are enabled only when necessary (occasionally). I overclock Defy to 1000Mhz with SetVsel, and underclock to 300 when screen off. With conscious observation over some time, I find that 1% battery is consumed around every:
- 2 hours standby with wifi off; or
- 1 hour standby with wifi on; or
- 3~5 minutes usage (calls, emails, surfing,...)
thats some amazing battery life u got there abc ...what rom are u using?
hey guys, just a quick question. with which setting do you think i'll have longer battery life: 800MHz/58vsel or 1000MHz/56vsel? btw, i got my phone stable at 800MHz/45vsel

I was using the orange 2.2, and am using the finland 2.2 now. Both have similar battery usage.
But I have uninstalled some stock applications which I don't use but keep running in background, like BlurHome.apk (with Launcherpro), InPocketService.apk, ToggleWidgets.apk (with ExtendedControls), WeatherWidget.apk (with FancyWidget), VSuiteApp.apk etc.

You may be right, I had the Xperia X1 something like 1 year ago.
I had until now FSC T830, HTC Hermes, HTC Diamond, Xperia X1, Samsung i7500 Galaxy (my first Android), Acer Liquid and now the Defy. As far as I remember I always had to charge every night (or every 2 nights at best)
Overall I think Android battery life is worse than Windows mobile was BUT I also have more background programs running now than I had in the WM days.
What I definitely don't like in Android battery life is lack of consistency. One week you get30-40 hours at a charge and suddenly 12 hours... Than you have to make detective work: look what new App might be the guilty one, check what's running in background, reboot and see if it happens again, factory reset, etc. I guess this is the price of freedom
Im on uk 2.2 and i get three days at a push i jus have a weather widget on sync every 3 hours.
Iv also undervolted 300/16 600/29 800/39 with setvsel on performance mode and up threshold on 99% and limit to vsel 1 when screen iz off
Im on three uk so im constonly on 3g and use no wifi etc etc with normal sms usage and a few calls through out off 1 charge

There has to be something wrong in your case. I find that there seems no wifi/2g/3g connection. Could that be the problem?
I dont use 3g ..cuz its expensive in my country ..and I only turn wifi on when I need it
And that shouldnt be the case ...I think id loose a lot more battery if wi-fi would be on all the time

Ughh battery drain definitely too fast.

I feel like I make a thread for each phone I go through. First Blackberries, then Droid X, now Galaxy Nexus.
I am getting pretty horrible battery drain that is definitely worse than others' Nexuses. I have gone to the extended battery now for a few days, yet in the morning, when I unplug from charger (says 98% but charged?), with brightness only a quarter of the way up from lowest, I can literally watch the percentage (battery number mod in corner) drop one-by-one each minute or a few...So if I am actually using the phone, you can imagine it drops pretty fast. Yesterday, with very very moderate use the phone was still dead within 5-6 hours. It was at the mid-80s within an hour or more. Again, with moderate use.
It is stomach-dropping watching the percentage number just go down and down. Yet my friend's Gnex using the extended battery his first day did not hit 85% yesterday until 5+ hours later. The battery stats page on mine shows nothing with high numbers except Screen and Android OS, so I assume no apps are draining it. I am rooted with unlocked BL, on bigxie's deodexed ROM with softkeys mod, battery percentage mod, and power menu mod. I have 100-something apps and many widgets but no battery draining/updating ones. Others with the same ROM report fine battery.
I believe after using the ext. battery for a couple days, it should be "conditioned" if needed at all, yet I see no improvement.
I'm getting very angry watching this drop.. For example, 40 minutes off the charger with almost NO use except for turning the screen on here and there, I am at 94% battery with Screen at 46%, Android OS at 34%, Phone Idle 11%, Cell Standby 9%, and Android System 2%.
And then 1 hr 20 min in, at 88% battery with 55% Screen, 27% Android OS, 6% Phone Idle, 6% Cell Standby.
This doesn't sound normal right? Keep in mind, those numbers are with almost no phone use..very minimal settings menus visited and one update from Market.
Jesus, literally almost every time or two I turn the screen on just to check these numbers, I see the damn battery percentage drop a number. Not even using the phone how/as much as I normally would be. This is infuriating. Luckily, it doesn't seem to drain much with the screen off.
Quit checking and wait til the bug is fixed and blood pressure stabilizes?
Crazy world, ay?
Update to 4.0.2 or 4.0.3 with an improved kernel = success.
Use the phone for 1-2 weeks to stablize battery life - mine is better now than it was when I began using it. But the kernel/rom makes a big difference.
Thanks. Any suggestions on with combo to use now? 4.0.3 preferrably I guess.
Then why does my friend on totally stock 4.0.2, non-rooted have that great battery life from the first day using the extended battery?? I'm pretty much basing mine off of his and other's who are getting ridiculously long life. I never understood how it varies SO much. We should all have the same relative to usage.

No. Because no two phones are set up the same. Too many variables to say relatively same usage. For instance, when i go to bed i get 2-3 hours standby per percentage point. Not everybody is going to get that.

Maybe, but the fact that I have no other visible outstanding draining factors, and I get no 4G at home and therefore have it set to CDMA only...I should not be seeing 1% drops almost every time I turn the screen on for more than 30 seconds. Especially with an extended battery.
God forbid I want to use GPS or 4G.

..And over the course of only a few minutes of the screen being on maybe twice and sending one email, I saw it go from low 82-83 down to 77. ****ing awesome.

You probably have a misbehaving app. Download better battery stats from the android apps and games section here at xda and let it run for a day or so and see what processes are being used the most and what your wakelocks are, etc.
Also, find a 4.0.3 rom with a kernel that can be undervolted and try that out.

Thank you, downloading now and will check it out.
I'll admit I'm using the GSM version so my experiences may not apply but for the first few days my battery life was utter crap.
Its been MUCH improved over the last few days, I dont have the wakelock issue and with the screen off the battery drain is literally only about 3% per hour, and thats with background data on.
YES, the screen DOES use a lot of battery, it isnt really avoidable and is somewhat expected with a 720p 4.6 inch super AMOLED screen.
The one thing I can recommend doing is finding a modded kernel and undervolting that CPU - It seems they've been really rather generous providing power to the thing, I've been able to take off at least 100-150mv across the board.

YES, the screen DOES use a lot of battery, it isnt really avoidable and is somewhat expected with a 720p 4.6 inch super AMOLED screen.
The one thing I can recommend doing is finding a modded kernel and undervolting that CPU - It seems they've been really rather generous providing power to the thing, I've been able to take off at least 100-150mv across the board.

This - My battery on the stock battery on GSM sucked first few days, and I was really concerned I made a poor purchase. But with the screen on probably 5 or 6 hours of my work day it lives through the day and just enough to get home after that. I can charge it at work too, which I usually do. On my day off it survived 18 hours and still had ~20% battery life left on 4.0.3 AOKP/Francisco.Franco Kernel
From my experience, the battery life isn't bad. I did install the "extended" battery as soon as I bought the phone but is isn't much bigger than the stock battery. I am on stock rooted 4.02. With LTE off I use about 2% per hour in standby. With LTE on it is almost double that (3-4%/hour). I have several widgets running and gps enabled. (wifi when available) I can easily get a 16-18 hour day and have 50% remaining when I go to bed unles I sit around gaming for a couple hours.
I may try a new ROM tonight but I expect it will probably make things worse.
Im running a bone stock setup and im getting 12 -14 hours a day... normally I read posts like the one skiddingus posted and wonder why I never can achieve those readings so i feel your confusion . I do have 4g on and gps off screen is about 1/4 of the way up brightness wise

Galaxy Nexus Horrible battery

hi guys,
sorry i'm noob and this is second time im posting on xda forum. I recently bought a Galaxy Nexus Made in korea by samsung. It's currently running on 4.3 latest update phone doesn't lagg or nothing happend like crashes etc but please see below major problems im facing.
Phone getting hotter from back side where camera is installed
0 to 100% it take 5-7 hours to charge ( I tried both wall and USB)
I charged the phone to 100% in night and i didn't use the phone night in morning when i check the phone the batter was at only 12% left. the phone eat all the battery in 7 hours the most battery was used by phone idle 57% and stand by 33% & i didn't put any sim card in the phone whole night and automatic wifi was on which was only 17% battery.
again i charged the phone to 100% close the automatic wifi and insert a sim card
The result is like
After 3 hours 57 mins battery was at 52%
Screen take 49% total screen on time 16m 1s
Phone Idle 22% 3h 41m 29s
cell stand by 10% 3h 54m 55s
Android system 5% (CPU TOTAL 1m 47s *** CPU foreground 33s *** Keep awake 1m 19s)
I don't know what was the battery time before 4.3 update becuz when i buy this set it came with 4.3 and i bought this 3 days ago. Is this a battery problem or the phone problem or its the android ???? any type of help is welcome
Thanks in advance
The Galaxy Nexus is known for its not so great battery. It also just depends on how you use it. If you are playing games, watching videos, etc. it will drain fast. If you just check a few things here and there, it will last longer. That's common sense. But yes, compared to other phones, the Galaxy Nexus sucks with battery. Theres not much you can really do software wise. The best thing you can do is get a bigger battery or a spare battery. I have a charger pretty much wherever I am so battery isnt an issue for me. But if you are someone who is on the move all day, I would suggest a spare or an extended battery.
EDIT: Actually, looking at your screen time, you are getting a bit above average on phone idle. Right now, my phone idle is at 8%

Yes i read that and i planned to get extended battery but the cell eating the battery while screen is off. I'm just confused about the OS 4.3 i read alot about that after updating to 4.3 nexus 7 user experiencing of slow charging and battery draining but as you seen in attached pic the phone eating battery without any usage the total on screen time is 6 min and in 3hrs 57 min 48% battery gone ?? so in your opinion what is the prob is it OS, phone or the battery ?

Well I see in your screenshots that it looks like you don't have any cell service. What could be happening is that your phone is constantly searching for a connection, which could eat up a lot of battery.
best bet

youre best bet if rooted and unlocked is to install a custon kernel and underclock it to about 1000 mhz ... install dark themed apps or theme chooser theme also us a black wallpaper .. turn off 4g . ... turn off nfc when not in use .. make sure youre using the oem charger to charge the battery .. use wifi whenever possible .. also turn off anything like hotword detection that is constantly listening

The mobile service was on but data service was disable i received 2 calls and some texts msgs 2 but they are not long or didn't took the battery. All syncs were off and location to. But the battery is going down very badly. Please see new attached files of last night. The cell was at 87% battery and in the morning the battery was dead.
Try using something like Better Battery Stats or GSAM and see what they say is draining your battery.
With the current info given, I would lean toward thinking it is a hardware issue. Perhaps your battery doesn't properly hold a charge anymore.

Few hours ago i left for office the cell was on 14% charging and turn-off the cell and put it in pocket. After 1 hour when i reach to office i was trying to turn on the cell but the battery was dead and then i put it on charging and it start from 6% and turned on. I think the battery is not holding charging . The battery is in made in Korea and have NFC details on it. I think its the original battery but its not use able any more. i will try above mentioned widgets before changing the battery.
new screen shots
didn't use the phone and it ate all battery. Any guesses what's wrong with the phone???
need a fast reply.
Try updating the radios (I don't remember how to do it. U dial #something). Also, have gps and 4g turned off. Auto brightness turned on. If u have the Facebook app, get rid of it and just use the mobile site.

4g/3g are off and i ticked use only 2G network. Facebook app is deleted brightness is set to auto GPS every thing is off but mobile consuming battery without any usage.... im just confuse about that its the hardware prob or i have to flash some other rom?
bump! any 1 with solution ?
U really need to get better battery stats. It will tell u specifically what wake locks r causing the problem. Idk if using only 2g is a good idea, u may be burning battery with apps constantly searching for a data connection. Can u access wifi? That takes up less battery than data (3g or 4g). U may want to buy a new battery, they aren't that expensive. U can get one on amazon for like $15. If that doesn't work, I'd try flashing a different rom, maybe even a custom kernel.
I am still running 4.1.2 because I like it better than the newer versions and my battery life isn't bad. I usually get close to 2.5hrs of screen on time. More than a day of standby. Obviously, if I make a lot of calls I will get less battery life. I'm running eclipse rom with leankernel.

Today i flashed Cyanogen mode 10.1.3. i didnt flashed any google apps just to check what eat battery. When i flashed the ROM the battery was at 36%. I used the mobile for almost 1 hour and on screen time was 54min 37sec and battery left 16%. The cell eat total 20% battery in 1 hour continues on without mobile data network and 2G was on. Wifi GPS every thing was off and brightness was set to auto. At 16% battery i stop using mobile and after 30 mins i check mobile it eat 6% battery in 30 min without any usage. then i truns off the phone and after 30 mins i tried to turn on the cell the battery was dead. then i plugged in the charger and i turn the cell on. The battery charge start from 10% but instead of charging i start loosing battery. then i charged for almost 1 hour on 0% battery and took 5 hours to fully charged. My cell phone drain all battery over night under the usage of phone idle 73%. I'm just confuse about that its the battery issue or its cell phone problem. and my phone getting very hot from back left side. I just need a good developer advise if this is hardware issue then i'm gonna replace the cell phone and if its the battery issue and hardware is ok then i will get a new battery and continue using and 1 more thing my phone get little hot even its turned off from back left side and sim jacket side.
Bump! any suggestion ?
I doubt a developer can answer that question. Could be phone, could be battery. I would try a, new battery just cuz it's cheaper than a new phone. Maybe go back to stock and see if that helps. If not, call Verizon and complain, they may send u a refurbished unit.

Try going to 4.3 via fastboot. With the flash-all.bat that will wipe everything. That might solve it
