Battery use mobile standby

Hi,
I have a question about mobile standby. The last few days i noticed batterydrain and tried to find the problem. Standby uses about 48% of the battery ( 1 hour 10% battery from which 48% is standby) This isnt normal i hope. My HTC Hero has about 2-3% the phone isnt rooted because i wanted to make sure there are no hardware failures.
I already tried a hardreset 2 days ago and the problem isnt gone
Is there anything else i can try except calling LG and using VIP warrenty?
i have the 10a version with 20110223 baseband

On my account i removed the original bloatware straight away and still have a huge battery drain..

Yeah, i have the same problem. I've upgraded the band version, but I still have this massive radio drain. I hope some techsavvy people sees this.

Battery drain during standby means that the phone is in sleep mode is it?

i think its caused by the radio

Sometimes when you install or tun a program it stays in the active processes and it eats battery out. Go to sett/apps/running apps and manually kill what you think it shouldnt be running. Dont kill google services, system apps or keyboard!

It took me 4 days to figure this out. As a former Nokia user, I thought "Use wireless networks" under "Location & security settings" meant A-GPS, but no, it means the phone will triangulate between cell towers to get your location (and is actually pretty good in it). But the downside is that it drains your battery very quickly. I think my battery life at least doubled, or maybe even tripled after disabling this setting.
Could be auto-sync too, if you have it enabled.
Funny thing is, that the original LG weather widget eats even more battery (through Google Maps) than "Use wireless networks", nice work LG!

Mine's unrooted too, and I can't see anything else under "Battery use" other than cell standby eating huge amounts of juice. Guess it's right, since the phone uses cell radio to get your location, but it sure was tough (for me at least) to figure out why cell standby was so heavy on battery.

I used setcpu with 1 rule :
Screen of :
max 312
min 216
and the result was less than 1% after 1 Hour without 3G ... My Internetflat expired so i'll test it tomorrow with 3G

I dont use location from wifi etc, i used to do so on htc hero and hero lasted 2 days medium use.
just called LG helpdesk netherlands and must say im not impressed. Totally zero knowledge of android and phones, called to times both kind of unsatisfied by the answer. New try tomorrow because i want a proper solution from them. Lucky me and dutch warrenty laws

Hi, my phone was pretty a drainer too, at least 30-40% gone after I wake up.
So what I did was I froze up apps like the F-secure, SmartShare, email...etc, tried extreme setting in juicedefender, and removed the stock weather clock. And wow, after 6 hours of idle, it just used 4% battery.

Hi.
Strange thing to me.
i've just rooted and remove fsecure ect...
the program that run abitually are
Email LG, BW, gosms, alarmdroid, elixir, gmail, scoremobile,phono and FB.
yesterday: at 17.00 the battery was 100%..
i've used the phone normally, and at the 1'00 the battery was 62% about.
This Morning, at the 7.00, the battery was gone. 0%, phone was off...
How use more than 50% of battery in stand by?!
the other night the battery goes down at least 10%...
i don't understand...

Edit will upload screenshots battery use when im home

Why are people getting amazing battrry life?

I've seen a lot of people reporting unreasonably(for me) great battery
life , like three days WITH usage. Even for CM7 based ROMs, they( most people seen reporting) also get a day and half or two.
But for my personal experience, I have used my phone six months, and the best I got is 1.5 days WITH usage.
How do those people have those huge battery life? Or am I missing something?

They using gingerbread bootloader's, and only 2g network with off autosync

Do you use juice defender? If you tweak your phone right up, then don't use it you might get 3 days if you did correct first charge etc, but in reality most people charge their phone everyday as they use them, it is a smart phone...ie a computer, my laptop lasts 4 hours! T there is no point in having a smart phone if you don't hammer the pants of it!

i'm facing pretty low battery life problem also
back then i remember when my phone is on idle, every 5 min only consume about 5ma(according to battery monitor widget), but recently i have no idea why , idle will consume up to 80ma every 5 min, i have very little apps installed and most of it doesn't have push notification nor sync
Another main point, i'm on 3G instead of hsdpa, i expect much better battery life to be honest, i'm currently on Juwe's smart edition 5.3

check the processes
First of all check what processes are consuming more memory and CPU.
Try using "Usage Timeliness Free" app, which will show you which application is eating up your memory thus battery.
It has got option to terminate unwanted apps as well.

Mine lasts about 7/8 hours at most with wifi turned off and some bloatware apps frozen aswell.
I've had the phone a year so I dont no if my battery is ready for the bin or if its something to do with flashing cf-root.
It runs out so quick I've got to make sure its on charge every night in case it dies and my alarm doesn't go off for work in the morning ha

One major difference people overlook is how hard the radio works to get a signal. E.g. At home with WiFi and 3G on I lose about 10% battery overnight of the phone sitting idle. At work I lose closer to 45% for the for the same period. Naturally when I use the phone it'll be flat at the end of each day.

[Solved] Battery drain even when idle

I charged my phone to 100 percent and left it untouched for 6 hours. Then a shock. It was down to 81 percent with absolutely no usage. Please help. I was not connected to either wifi or data.

Akilesh - you need to see if any app was running. Over the weekend mine went from 60% down to 12% because Titanium Backup got stuck trying to delete an app and kept my phone running at 200mhz which will drain your battery. Go into settings/Battery and see if any app is at the top of the list. Your phone should not lose 19% if you dont have anything running/syncing etc. A simple reboot took care of the stuck Titanium Backup issue with me.

I am on full stock gingerbread with no root. Cell standby has consumed about 45 percent of drain. I'm now worried. Is there a way to calibrate the battery or reset battery stats?

Hello Akilesh, you could use an app called BetterBatteryStats to monitor your battery usage statistics.
You could root your device and then install Titanium Backup Pro which will allow you to freeze or uninstall unnecessary pre-installed applications by Samsung, which are aptly termed bloatwares.
If you do choose to root your device, kindly follow this guide by dr.ketan, http://forum.xda-developers.com/showthread.php?t=1424997
I hope this helps a bit.

screen brightness is one of the prevalent causes of your phone's battery, lower it down to a minimum level. Check if you have syncing apps in the background too, Uncheck background sync datas or account in settings if you have then check.
Now, install cpu spy from google play https://play.google.com/store/apps/...251bGwsMSwxLDEsImNvbS5idmFsb3Nlay5jcHVzcHkiXQ.. and check if your phone is in deep sleep or not at all.
Also, quit using live wallpapers (if your using one), though as you said your not using your phone for 6 hours.. the fact that if you do have a live wallpaper running, that will still eat up your phone's battery juice.

maybe it's about high time you consider rooting your phone.. so that you can install titanium backup and shoot those power hungry apps that are hidden somewhere in the framework of your system.

Yeah I'll root in a short while cleo. And is titanium back up useful is reducing battery drain?
Sent from my Android Rocket using Xda Premium

titanium backup is a tool to uninstall and freeze unnecessary apps and samsung bloatwares on your phone. When your going to remove those apps, you are not just reducing power consumption that those apps uses daily on your phone... you are also freeing some ram spaces on your phone's storage.
BTW: My name's John and 'Letters to cleo' is a name of a band that I like most.

In case you opt for a free alternative to titanium backup, there is this app called "AntTek App Manager". I found it by chance and it works exactly likeTB pro (in terms of uninstall and freeze). You have to be careful while using either of these programs

i think you install an app that its drain your battery . if you dont find that you may reset factory your phone

Just got rooted again. Now freezed all bloat-ware. Will check out how it works and post back again.
Edit : Feel the phone running a bit faster after freezing some 15-20 applications.

dont forget to try recalibrating your battery as well.
Mind you, rooting has far more greater advantages than disadvantages.
Check later on if your getting that perennial issue or not anymore...lf by chance it had made some considerable differences, then your a happy camper..
Cheers bud!

If your phone is getting into deep sleep, it can't be any application! It has to be something to do with wifi/Network! If you run 3G, try disabling fast dormancy. That did me wonders!

Battery Drain
Hi Guys,
I have similar problem. My battery started playing up and keep draining suuuper fast even at full charge. My phone and bat are already 11 months old but I don't thin the battery should die with this short time. I have data always on and screen brightness set to minimum and it has been like that since I have it with no problem. Now, after charging to 100% and removed from the outlet, then start opening an application, it will freeze and won't turn off. I need to remove the bat out to have it rebooted and it's still the when I try again. Other behavior is that the screen will flicker, will turn to airplane mode, and it will turn off even when fully charged when I launched an app. Note that (power saving is OFF and just the same when it's enabled) I can now only use my phone well when connected to charger. Any help would be appreciated. Thanks.

there are a lot of people facing similar issues with more than 9 months old battery... mainly indicates a battery problem.. but first you should install betterbatterystats and check for wake locks and other apps using the phone when idle and eating up the battery..

My biggest drain according to bbs is Google maps, it's eating my juice when in idle, although I can get into deep sleep bbs says maps is causing wake locks.
Should I just freeze it with titanium? I don't really understand bbs much lol

I uninstalled all the games I had on my phone and battery afterwards was amazing. Not sure what games u had on ur phone but dead Trigger mass effect seemed like they used battery even if not played. Now star wars angry birds and contract Killer zombies 2 doesn't to use that much battery when not used. I think dead Trigger must be constantly be doing a task in the background. I got from 6 7 hours to 15 hours with 12% battery left. Not sure why some games in idle still or when not being played still eat the battery like crazy. So my tip is uninstall all games and see how it battery life is afterwards.

Facebook app is a battery eater, even when not in use. It's trying to sync contacts or others notifications constantly. Even when you disable those options.
Uninstall that app and use Facebook through a browser like Dolphin or so? That's what i do.
Also read the tips in this thread: http://forum.xda-developers.com/showthread.php?t=2013469
I'll post my final configuration in that thread soon. I have my phone at stand-by now for 6 hours and it's still at 100%.
I found the best way to save battery is to not use 'active/changing/moving" widgets, remove or freeze battery eating apps and underclock.

Wrong post.

Stock trega core concept is awesome but it depends on usage. As said in power Management demo, if screen is "on" and some background program is running all cores will be on, which consumed a lot of battery. And try charging your mobile only when charging falls to less than 5%
And remove it when it's fully charged. and I suggest you calibrating your battery really calibrating my battery worked a lot.
I have been vulgarly using my mobile a lot. i never faced any over consumption. Overall I am really happy with the results. of course I'm never disappointed by my battery till today. I love my 4X.

Without root you will not get good results.. Even if you calibrate your battery. In my opinion, the first step to get a better battery life is rooting your phone.

That's normal for the stock ROM, flash my V3 ROM you'll have 2 or 3% drainage over night.

So strange,there are no significantly changes in DMod, compared to the base BenzROM! Essentially frameworks and apps are the same

I know man it doesn't make sense but I can't wait for another better rom that will hopefully fix this issue with a clean install.

Yes but you're forgetting about build.prop tweaks, they play a big role when it comes to battery drainage.

I just installed Benz rom, so i am hoping for better battery life.But there is also one more thing i noticed.I installed no frills cpu and i noticed that minimum frequency is 1 ghz !!! I set it to 200 mhz and i think that will make a huge impact on battery.I will be posting my battery stats picture soon.

So many advises about installing other rom. I think you need to try to remove huge battery drainers first. Try to disable Picasa web-albums sync (this **** eats alot! ) and some other sync that you don't need. You need to change it for each Google account you use on your phone. That's all. This small change halped me alot with battery drain and, I hope, will help you.
Also, you can freeze apps that you don't need to. It can be made without root.

In screenshot you have a very weak gsm signal in your area. This drains your battery.
If you don't use 3G/HSPA mobile data, you can try to manual switch to 2G network (2G band use less power from your battery).
HTH,

Ok, so installing a new rom and messing with CPU frequencies did help after all.I installed Benz rom and changed minimum cpu frequency from 1 ghz to 200 mhz.Battery now lasts 2-3 days with light use and about 1.5-2 with medium use.Battery discharge overnight is about 10% with sync, wifi etc. turned on.

hmm,i dont know what apps you have installed on your phone,but when i installed Dropbox app few days ago, there was a massive battery drainage overnight...it eat my battery between 30-35% overnight...and it used to be only 3-5%...
of course i uninstalled the app and now its back to normal,only 3-5% drainage overnight(wifi and sync off)...
