Hi,
I'm wondering some things to optimize my battery life, but couldn't find any answers so far:
1) When Wifi and APN both are ON, Wifi will get priority. But the APN-setting is actually still on. Will it drain the battery, or should I always turn APN off when Wifi has been connected?
2) I have set Ultimate Juice (or Juice Defender) to turn on APN every 10 minutes during 1 minute to check for updates. But when I turn off APN, Juice Defender can't turn APN on himself to check for updates. That means that I have to remain APN ON. Doesn't that drain the battery, or is Juice Defender turning APN off on his own way?
3) I noticed that when the screen is off in standby, Android will turn off Wifi and APN. People are saying you should turn off APN and Wifi when not in use, but since Android turns both off while screen is off/standby mode, what's the use of turning both off manually? I think you could even turn them on all the time since they will get turned off when the screen goes black.
4) e.g. You're in a situation without any internet access. Apps like the Friends Stream, or Mail want to check for updates every 5 minutes. the consequence is they can't update because there's no internet connection. Does that action always drain the battery some more?
wtf no one??
under the wi fi advanced settings.. you can set wifi to never sleep... this should mean that your not using the apn connection...
I think apps try to update and if they do not succeed, it will be cancelled. I doubt the apps will continously check for updates until they get a fix. Same with Weatherbug. I sometimes see Weatherbug last updated hours ago, even when I have had internet access for the past hour (I have set it to update every hour). That was when I had unchecked 'enable always on mobile data'.
There are options available for wifi under advanced menu to set it to always stay on, or shutdown after 15 mins of sleep.
There is also an option available to always have data connection on. This will keep data connection alive even if phone is set to sleep.
Do you mean "mobile data connection" everytime you call it "APN"?
There's WiFi and that; two ways to access the net which pull power. WiFi can be disabled quickly and easily through the widget. So can the mobile data network: http://yfrog.com/0ymobilewidgetp
Leaving it to 2G when you don't need 3G or when 3G reception is bad saves much power. I'll need to do more experimentation before I can answer your other qs with assurance.

I searched and was not able to find anything related.
Has anyone thought about this?
I enjoy having a WiFi sleep policy when its idle. Maybe something like this exist for Mobile Networks?
I'm pretty sure something like this already exists. Check Settings>wireless&networks>mobile networks>enable always on mobile data. My experience is that if you disable this your phone will go go idle on mobile data about 10 minutes after you turn off the screen. The problem is that this will delay your email and data synced items by about 30min to an hour depending on your settings.
I experimented with it and didn't really notice a huge benefit to the battery life. But I also constantly pull my phone out to play with it (which re-activates on the network, i think).
Has anyone found an app to toggle the 4G on/off yet? I realise it is disabled in Android 2.3, but I see they have it working for the Evo and maybe others. I also saw at least one paid app that says it works, but I don't want to pay for it and then find out it doesn't work.
Thanks,
All the 4g toggles I've tried work on WiMax only
Why do you want to disable 4g? Its not like an lte out Wimax radio that causes massive battery drain so why turn it off?

Data Enabler Widget
really? i did not know this. I'm not sure what Sprint uses, but i know when i had sprint if i disabled my mobile data it made my battery last MUCH longer.
most of the standard 4g toggle widgets included in most widget packs, i.e. widgetzoid, do not work on this phone.
the one toggle i have found to work is called "Data Enabler Widget" by "farproc" it is available on the market.
Be aware that picture messaging does NOT work without 4g data on, and you must re enable it before you use it. (wifi too for some stupid reason)
why disable?
I want to disable it primarily because i don't have unlimited data, but also to extend battery life as well. If there is no toggle switch that works I will just have get used to the extra steps of turning it on and off through the settings menu.
Yesterday I used 50% of the data that I would normally use in a month, because I thought I was using wifi, but apparently was not. That tells me that the phone either is not holding the wifi signal at home very well or the wifi is not overriding the data connection. Either way, I need to be turning off the data connection when I am at home or using a wifi hotspot.
if you would take the time to read my post, i just provided you with the exact app you are looking for. it is a widget available on the android market. it is called;
DATA ENABLER WIDGET by farproc.
kthx.

Another option then is any this party power control app. You can turn off mobile data through those.

I always used the power control app on my Hero, but unfortunately the one for this phone doesn't include a data toggle.
reata Enabler Widget
ApexZeph,
I tried the Data Enabler Widget you mentioned and it works perfectly! Thanks!
Sprint's 4G is not the same as HSPA+. HSPA+ is just 3G, or if you wanna feel better, 3.5G. It runs all the time and doesn't use extra battery because you're still only using the 3G radio. Sprint's 4G is WiMax, which is basically glorified Wifi and requires a totally separate radio. It works like Wifi; you turn it on, wait for it to scan and connect to the 4G network (which doesn't even deserve to be called 4G because it sucks ****).
Since you guys are on GSM, what you could do is disable 3G data and that would do it. You'd go to EDGE, but you'd save a ton of battery. Again, 4G is just a marketing term for you guys; you're still just using fast 3G.

Its not?
4G on idle 2 hours: 18% drain from 100%
EDGE idle 2 hours: 5% drain from 100%.
4G is a bleeder.

HSPA+ uses a lot more power than EDGE. Programs like Juice Defender use this fact to their advantage and disable HSPA when the screen is off, and I hear it just about doubles idle battery life.

HSPA+ = 3G. Yes, 3G uses more power than EDGE. It has always been and will always be that way. There is no magical "4G" toggle because HSPA IS 3G. So the only way to turn off your faux-G is to turn off 3G data and fall back to EDGE.
There is no 2g/3g(4g) toggle that works on the stock roms. It will just take you to the settings page where you have to choose GSM/HSPA, GSM only, or HSPA only.

GSM only = 2G only
HSPA = 3G/4G only (remember, they use the same radio)
GSM/HSPA+ = whatever is available, with HSPA having priority.
Hey everyone,
I spent 4 hours this evening reading up on how to Root, CWM, and Flash a ROM onto my SGS2. Contained in one of the threads (I believe it was [ROM][NOV 14]Bombaridier V.2.0) I came across a brief mention of a program which allows the user to toggle 4g Data on/off simply by clicking the icon. I downloaded it, and just now I flashed Bombaridier (awesome ROM btw). That problem is now gone (obviously) and I can not, for the life of me, remember what it was called. I'm hoping someone can throw me a bone here so I don't have to sift through hundreds of pages again in order to find it. Any help would be greatly appreciated, thanks
Nate
You are probably speaking of Juice Defender but Ill let you know of another program that is better IMO. It's called LLama its event based. I have two events 1. Mobile data on when screen is on and 2. Mobile data off when screen is off. Juice defender does the same thing but every fifften mins turns on 4g grabs emails etc and then turns off again. The reason I think LLama is better is because in my job Ill forget about my phone while working and pick it hours later. yesterday my phone went 2hrs before it dropped from 100% to 99%.
the only problem I find with having mobile data off when screen is off (llama) personally is that I use GV as my text app. and if my mobile data is off, then I won't know that I've received any text.
When in the office, i do not have wifi, so I rely on my data connections for texts. Is there a condition where when the screen is off for 1 minute, then mobile data will be turned off and turn on again every 10 minutes or so (like juice defender) to help me check if i received any text?
Hi all
How are you guys manage to get whatsapp notification almost instantly when the screen is off ? I have no 3G (data plan) and the "always" option on WIFI shoould be a solution but it will drain battery. i f you chose "never" or "pluged in", then you wont receive notification until you unlock the screen.
if i put syncronization ON, on the device settings, will i get the whatsapp notification, since it will have to conect to wifi?
You have to have a consistant internet connection, otherwise the phone can't recieve the message!

damn... even my old iphone 3g had a Wifi conection that would conect itself on intervals and not all the time so the battery wouldnt drain.
ty anyway
No problem
Just have it connected all the time, for me Wi-Fi doesn't drain the battery much (if it's connected to my Wi-Fi)

You can try Juice Defender, there is option to switch data on custom intervals.

can't find the option to switch the data usage on custom intervals. Any special version of Jucie Defender?

Have you tried with WiFi on all the time? I've never turned it off (well, almost never), and my battery life seems as good as anybody else's.
Hi all!
So I'm on holidays in the US, and coming from Europe I don't want my data to be activated, since i would have to pay an unreasonable amount of money per day. So i deactivated the roaming option in the settings menu, but the data was on after an hour, which resulted in me paying 24h of data.
So to avoid this to happen again, i deactivated mobile data altogether, but the data keeps turning on!! So i paid another 24h. Now i switched on plane mode, but then i cannot get sms or anything.
Does anyone have this issue? Or how to fix it?
In the attached screenshot, you can see how mobile data and roaming are deactivated, but the H+ is still active in the corner.
Thanks!
Did you try restarting the phone with the phone in airplane mode and without airplane mode?
The thing is if I do that and checked if it worked i might be charged again. It was just in case someone had the same problem and knew the solution
