Worth a try... let see!, thanks.
[Nexus S General] kerry_xu_cs:
it doesn't sound like reasonable
[Nexus S General] albundy2010:
If there is wifi network available you should ALWAYS connect to it as opposed to cellular data. Does not matter whether screen is on or off. If you got wifi available use it at all times.

I find wifi drains significantly more battery than when on the 3G data connection.
[Nexus S General] BrianDigital:
How does this help when I'm out in the world with wifi off?
[Nexus S General] kyokeun1234:
What if Android System itself was the main reason why my battery is terrible?
[Nexus S General] rony1234:
I agree, having wifi off would end up using cellular data, a very quick and fast drain on the battery. If you have wifi most of the time then this shouldn't be disabled, I found that having wifi on all the time actually helps improve battery life since my phone doesn't hog onto the cellular data network. I am around wireless most of the day & night, so I end up using more of WIFI.

This particularly makes sense during the nights, when the phone is hooked onto wifi instead of cellular data.
[Nexus S General] thegtfusion:
My dads nexus runs stock unrooted 4.0.4 and he got 2.5 days of battery life from a full charge.. (mobile data on the whole time and wifi to update some apps. Ill try to make a photo if he gets home tomorrow. ( i checked this evening and it was at 29% (2 days and 19hours on battery)
[Nexus S General] bigmizz79:
People get those outrageous hours of use because they don't use the phone..I had to switch to my sensation the battery is so bad..my wife knows nothing about phones and she keeps saying after she updated to 4.0.4 the battery is absolutely horrible.**

What is the point using smartphone without internet connection?
[Nexus S General] IIIV:
Or use battery saver apps, like GreenPower, which you can set to only sync your email and/or apps once every 15 mins./30 mins./1 hr./etc. You can also set it to "Night mode" and schedule it to automatically turn off WiFi and Data connections during a certain period (I set mines at 12am to 7am, so I won't be bothered during sleep with any email and/or app notifications... and also save my NS' battery).
[Nexus S General] rasengan82:
Anybody know why I get better signal when I am connected to WIFI? Once I go to 3g, signal is not as stable (still descent)
[Nexus S General] jesusice:
Because Sprint 3G sucks and your Wi-Fi doesn't? O.o
[Nexus S General] rasengan82:
No. I'm asking about cell signal.
[Nexus S General] Harbb:
While you're using WiFi the phone will be happier to switch to 2G in a low signal area, assuming 2G signal is good. While on Data, it'll try and enhance the weak 3G since it's much faster.

I don't know the names of 2G/3G/4G services for the CDMA network, but they should show up on the status page and tell you what protocol is being used with the signal strength.
[Nexus S General] BrianDigital:
There's no 2g mode for sprint unless 1x is then might as well turn off mobile networks
[Nexus S General] Harbb:
I know very little about CDMA and Sprint in general, so i just got some info from wiki. Unsure whether i misinterpreted it or the info is off mark, but it does say there Sprint does have some form of 2G network - with some light reading this seems to be the 1xRTT network which is a part of the "3G" CDMA2000 family.
[Nexus S General] Braneless:
Yeah. I've been shocked at the lack of Android user proficiency since switching from the Evo forum to the Nexus.

I figured that people over here would be more knowledgeable since the Nexus is a developer's phone. That notion went out the window after reading the first couple of Nexus General threads.
[Nexus S General] AeroEchelon:
How is this related to 4.0.4? You could do this on Gingerbread and 4.0.3.

Regardless, WiFi uses less power than a 3G connection. WiFi only has to communicate to a router meters away while a 3G signal has to communicate with a cell tower kilometers away. Turning off WiFi while sleep will turn on your data connection. If you're in a location that provides weak 3G then battery drain will be even worse as it will constantly poll for a better signal.

I can only see this method saving battery life if you already keep your data off to begin with (as I do.)

Just because it is a dev phone does not mean that only developers will buy it. View the dev section if you want more "knowledgeable" posts.
[Nexus S General] Ieatnoobs:
I have two tips for longer battery life:

1: don't use your phone often

2: use a black wall paper. Uses less power.
[Nexus S General] bmszabo:
Try Battery Defender, from the market; it reduced my battery use to <3%/hr.

Ya don't say?:p
[Nexus S General] albundy2010:
1. Don't take battery advice from people who have no clue what they are talking about.
[Nexus S General] deetailed:
What drains battery:

1. Apps syncing in the background

2. Radio looking for signal they can't find

3. CPU

4. Screen

Solution:

1. Only let apps autosync if you really need it. Otherwise you can sync it manually. Use BetterBatteryStats to identify battery draining apps, like Facebook, Google+ or Picasa sync.

2. Turn wifi on all the time in a place with known wifi signal. Turn wifi off when you're somewhere with no wifi. Don't set Power Saver (or your battery saving automation app of choice) to turn on wifi periodically. Use only 2G if you're in a place with bad cell signal, or if you only sync a small amount of data (like emails and IMs). Use 3G/4G when there's no wifi and you need the speed (like for downloading or streaming).

3. Experiment, find the right kernel, governor and scheduler for your needs.

4. Set the brightness to as low as comfortable. Minimum is good enough for most indoor use.
[Nexus S General] jesusice:
1. Don't worry about.

2. How far is anyone ever from an outlet?

3. Just use your phone and charge it when you can.

4. If you want a battery that lasts days don't get a smartphone.
[Nexus S General] chronophase1:
Pretty much. As long as my phone lasts 12 hours, I'm good. I always bring my charger with me just in case I plan on staying out late and just charge it up at work. Its like some people act like they can't charge their phones before they go to bed.
[Nexus S General] sdhanjal15:
As long as I get through the day I'm alright
[Nexus S General] LordLugard:
You guys forget how cheesy horror movies start.

Driving through the woods with a 30% charge NS4G thinking I'll just charge when I get home, but then for some reason you have to reboot phone and all of a sudden that 30% just dropped to 19% (happened to me several times before)....and some hooded shadowy figure begins slow walking you while you burst a tire...etc..

[Nexus S General] BrianDigital:
Again if switching to 1x to save battery life forget it that and turn off mobile data

Anyquick run down through mobile networks settings would show that you cannot change to 2g mode or using a market app to switch to 2g also does not work in cdma rooms

There's a reason its left out its slow and used for SMS and maybe phone calls never looked into cause any research into the matter is like reading guides to setting up 56k modems today

[Nexus S General] themacro:
I find that, in certain unsecured “open” networks, leaving wifi on eats up a lot of battery, whereas if on a secure wifi network with WPA2, for example, leaving wifi on will save me battery instead. It's weird.

As for the sleep policy I just have it set to “always on” but turn off wifi manually in unsecured wifi areas where it'll just drain my battery.
[Nexus S General] davidsteele1975:
You beat me to it (themacro). Most Wifi hotspots use less power compared with the mobile network, but some use lots more. The store where I work has free public Wifi but you have to sign in. It feels like when using it for a long period of time, the device has to re-confirm credentials or re-handshake or whatever it does, but it hurts battery life.

Using the home Wifi, battery life is immense. :)
[Nexus S General] res1n:
I've noticed better battery life on 4.0.4 using air kernel and setting CPU to lazy and using automatic brightness. However it compares nothing to the battery use I used to get on GB using matr1x kernels.
[Galaxy S II Q&A, Help & Troubleshooting] blade30p:
hope this is in the right place.​

I downloaded & installed this game to test it out...

https://play.google.com/store/apps/details?id=com.cupra.rec&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS5jdXByYS5yZWMiXQ..

but I now cant un-install it. if I go to app setting I can press un-install but it just doesn't remove it. I have app monster pro on my phone but the game doesn't show up under installed apps so cant use that to remove it. the game files take up 1gb of space & I want it back!

pls help? :mad:

EDIT> I managed to sort it myself, can a mod pls lock/delete this thread pls?
[Galaxy S II Q&A, Help & Troubleshooting] MauriceGalaxy:
Install Titanium back, perhaps this program will see the game. Otherwise, just delete the files, so you have your space back.

Most of the time this works for me.

Edit: would you like to share your solution, so others might benefit from it?
[Galaxy S II Q&A, Help & Troubleshooting] blade30p:
of course, I just deleted the game files on my sd card then once I had done that it simply un-installed easily from with in Appmonster pro. I think the un-installer was having trouble with the nearly 1gb in size game files :)
[Motorola Droid and Milestone Q&A, Help & Troublesh] GBLOCK51:
The device is a Motorola Droid and it is completely bare bones STOCK. I wasn't "allowed to play" with this one! It is my fiancé's old phone and she wants to sell it.

Problem - I've tried both the hardware and software methods to hard reset it. Both methods get stuck on the black Motorola logo splash screen. I've attempted both methods numerous times with the same result. I have searched xda and google, but haven't found an answer. I've found similar threads, but they relate to rooted phones and the update.zip seems to be the fix.

Any thoughts or suggestions would be greatly appreciated...thank you for your time.
[Motorola Droid and Milestone Q&A, Help & Troublesh] Burrito Bandit:
Did you check droid forums on how to do a hard reset?

I would also try updating the phone cause that could be part of the issue. If you are worried about personal info like pictures and contacts being taken you could possibly try rooting it and plugging your phone into the computer and wipe all the information manually in windows explorer. I do not know if a root is necessarily required though. Also try contacting the carrier or manufacturer.

Cheers

Hey guys,

I have been using Valhalla Blackedition for a while and it's been fantastic.. well that is when it's working fine. Sometimes, when i don't reboot my phone for awhile, my phone gets just jammed up and when go into text messages, I can see that my phone reloads all the names and sometimes quits out of messaging. This happens to other apps too like google search, call mode and such. I searched tons on the forum but i couldn't find any answers.

Anyone has this problem as well?

Same Problem

Hello, I had been using Valhalla Final for a while but then switched to AOSP Final due to this problem. With the AOSP Final it would never have the quiting problem and it was great but I really like the style and look of Valhalla. So I have recently switched back.

I have tried doing resets and going in to cwm to delete the Dalvik Cache and fix the permissions but its only a temporary fix. At first I thought it was cause I was using the Adrenaline Shot or switching kernels so I just flashed the rom and used it for a couple of days but no luck.

If anyone has any other suggestions or know what is causing this please let me know I appreciate it. Thanks.

I was going to post a thread about v6 supercharger, but haven't done so yet. I've been using the latest v6 supercharger for a while, and it has cured any and all random close issues. It basically changes the way memory is managed in the OS. It also makes the launcher extremely hard to kill, negating the need for the build.prop trick. All in all, I would try out the latest beta release of v6 supercharger, just follow instructions in the v6 supercharger thread (its on xda).

Gremlin Remover

Ok so I tried the 1-click gremlin remover and everything looked great. After about 12 or so hours my messages started closing again. This is really frustrating and I would like to have this fixed.

@erikmm, I would like to try what you said but I'm not sure on what you're talking about. If you could, can you explain in a little more detail on what to do? Thanks.
[Samsung Galaxy S (4G Model)] This_dude:
No fix yet.

I have also applied the V6 supercharger to the phone and no luck there either. Looks like I am going back to AOSP Final since I had no problems with the closing there.

If anyone has anymore suggestions I am all ears. I really don't know why this has been a problem for only a few people. Anywho, thanks to all that have given suggestions and those of you who will continue to.

[Motorola Atrix 2] ewandroid:
atrix 2's battery life is well known to be long and at least it can last for a day and half with mediocre usage.. But in this 2-3 days, my phone feels hot and the battery drains so fast! I don't know what I did, my phone is rooted and using OTA stock 2.3.6 and some build.prop tweaks.. I already restored it to factory setting but still no luck

NEED HELP!!:(
[Motorola Atrix 2] mtnlion:
Usually a rogue app
[Motorola Atrix 2] lilhaiti:
Yep...usually it's a rogue app that causes this.

First go into Setting-Battery & Data Manager and then click on the big battery and it should tell you what's using your juice (it's best to do this after you've been on battery only for a while).

If it shows nothing out of the ordinary, then uninstall the last few apps you installed (usually games are the culprit).

If none of that helps then you could try calibrating the battery, I use BatteryCalibration (available in the market)

And the last resort is to take the phone in for repairs/replacement

Good Luck
[Motorola Atrix 2] razholio:
I agree with most of this, but you would probably want to try a factory reset before taking the phone in for a replacement. Just do a titanium backup of all your apps first so restoring is faster and easier.
[Motorola Atrix 2] lilhaiti:
I would normally suggest that...but he said in the OP that he tried that all ready.
[Motorola Atrix 2] ewandroid:
thanks for all the suggestions. I have did a factory reset before but still no luck. Maybe because of the rogue app you guys talked about, my battery data shows that Temple Run apps used 50% so I will try to uninstall it. Its a shame though, it is a nice game:(
[Motorola Atrix 2] ewandroid:
it still the same:( i dont what else i need to do.. i think the cause of this problem is because there's something that keeps downloading.. when i check on Onavo, android os + others is always downloading. i can't restrict it to wi-fi only. Any idea?
[Motorola Atrix 2] lilhaiti:
Get rid of Onavo
[Motorola Atrix 2] ewandroid:
i got rid of onavo but it is still the same.. did any of you occur the problem where the phone gets overheat?
[Motorola Atrix 2] lkrasner:
Temple run was bad for me. Battery calibration fixed it. Make sure to fully kill and charge as recomended.

Hello all,

I hace veeb seaching the web for this but didnt find anything, so am sorry if the answer is out there.

Here is my problem : when i open app with white background (gmail gtalk), i can see remnant desktop icon like the bottom ones or the ones i added on the desktop.

Any one got this issue yet ?

I guess i will have to change the screen, but any tips welcome to solve that.

do you know of any software i could use to generate this video ?

[Samsung Galaxy Nexus] svtfmook:
any video rendering program like vegas pro would work
[Samsung Galaxy Nexus] kristovaher:
If it is there all the time, then it is a screen burn-in and possibly result of too long screen-on times. This happens with majority of screens out there to some degree and there's not a lot you can do about it. It will happen to every device sooner or later, though usually should not become evident before a year or two, depending on use.

But if it is temporary and 'fades' after ten or so seconds, then that's perfectly normal.
[Samsung Galaxy Nexus] guyiom:
Hello,

In fact it is there all the time.

Do you think warranty will work ?

[AT&T Samsung Galaxy S II SGH-I777] WiFivomFranMan:
my better battery app shows wifi running all the time. My battery is getting nuked. When I look at the android menu it says it is the screen sucking up the battery, even though the screen was only on for a short time. Anyone else having issues?

I wasn't having any issues with the 2.3.6 until right there at the end and then it started having the wifi draining issues. I was hoping the wifi issue would have been fixed in the ICS release. I tried doing a factory reset, which didn't help. I uninstalled the att hot spot finder app, didn't help. Is there a way to clear the wifi configs or reset the wifi?

I also notice it will disconnect from the wifi and can't see wifi networks even when hitting the scan button. I have to turn the wifi off and back on to get it to work.

[AT&T Samsung Galaxy S II SGH-I777] twiggums:
Pretty sure this is the same way it's always been that I remember, unless you goto advanced settings it will stay on with the screen off, it shouldn't really kill your battery though. I see minimal impact with my wifi on, I've even read it's better on battery due to less awake time on data polls. The exception to this is if you have an app that goes data crazy when it's on wifi, and keeps the phone awake. Then there was also the issue with the uckk6 firmware, but I don't think that issue is still going on with the ICS ROMs I've tried.

Edit: Was just reading and I guess ATT leak might still suffer from the goofy KK6 bug.
