Why does data network mode = ON kill my battery? - Galaxy S II Q&A, Help & Troubleshooting

With data network mode enabled, my battery lasts around 24 hours. With it disabled currently has 63% remaining having been active for 1 day 10 hours.
Is there any kind of happy compromise where I can have all my data services active but not have the horrendous battery drain?

JuiceDefender. This is the ultimate answer to you question. It manages your data connection when your screen is off. With a lot of customization options, like what it has to do at night.
It disconnects data at given intervals of let it be 5/10/15/30/60 minutes. And then turns it on for 5/30/60/etc seconds, waits for everything to finish syncing, and then shuts down the data connection.
Android 2.3.4 + Juice Defender Ultimate, gives me 2 days of batterylife easily. With checking my screen very often.
Of course, it's all based on how you use your phone.

[Q] Idle Battery Usage

A few nights ago I killed all the running apps on my atrix and turned off all network services like bluetooth and wifi except for mobile data. 9 hours later (with no use) the battery had dropped seven percent. Then I turned off mobile data as well and did the same thing. 9 hours later the battery had dropped 5 percent. On my iphone 3G I left data on and 9 hours later the battery had dropped 0 percent.
It seems to me that because android has multitasking, things that you don't need stay running in the background and although the battery usage by each is minimal, after long periods of time the battery usage adds up. On phones like the iPhone 3G, there is no multitasking (I didn't use backgrounder) so no applications or services were running and therefore no battery was drained.
My question is if there is a way to turn every application and service off other than those that govern calls and texts so that the idle battery usage is minimal and more comparable to phones like the iPhone 3G?
There was a thread about this in the nexus one forum. Miui if my memory serves... It consisted of running apps right off the sd card via dark tremors and some serious autokiller memory optimizer tweaks.
I heard mixed results of great battery life and corrupt sd cards. Either way there are better ways of achieving good battery life whilst keeping that snappy multitasking of android.

Is miui available on the atrix? It doesn't show up in their list of supported phones?
If anyone else has any other solutions please post them too.
Yea, I don't think you can get miui on the atrix.
BTW, I instead of just disconnecting mobile data I turned on airplane mode and it lost 3 percent battery in 7 hours (cell standby was gone from battery usage and phone idle was at 90% with display at 5%). Extrapolating to 9 hours makes it 3.7% which means that simply searching for a connection contributes to half of the battery usage when idle.
Putting my phone in airplane mode is not a good solution... does anyone have any other ideas?

Battery life without turning off wifi

I just got this recently and it seems like battery drains pretty quickly when the wifi is left on, for some reason the wifi connection stays on constantly unlike my Galaxy S2.
Is there any way to get wifi to sleep when the screen is off? Not that it's a big deal, but it seems like samsung should have thought about this so users don't have to constantly toggle wifi on and off.
Are you sure it's wifi that's doing it? I get barely 24 hours on standby with no apps running & sync switched off.
I've read that the chipset used isn't very efficient when in standby but the status reports on my 5.0 say that when in standby, 77% of the battery is being consumed by cell standby, despite the device having no cell functionality. Wifi is reported as consuming only 8%.
I've asked Samsung to comment & got a very helpful "return it to the retailer"...
I saw a recommendation for Juice Defender but haven't tried it yet.
The Battery Usage estimates for idle, standby, and wifi aren't always reliable - they assume Samsung got the powerprofile.xml right
For me - I know that wifi is significantly increasing my drain, but since it still lasts 4-5+ days of light use even with wifi always on, I don't mind.
This is for the 5.0 with the stock /system firmware and my kernel - 4.0 might be different due to a smaller battery. I see no Cell Standby usage reporting.
I've only had it a few days, but with wifi on, the battery lasts a bit more than 24 hrs just sitting there, I've turned off the wifi about half way through the battery and it seems to be draining at a slower pace now....
I'm also on stock Galaxy 5.0.
It's all very odd. We're getting around 24 hours & others are reporting 4-5 days.
I get 2 days to 5-10% almost everytime. Not much use, wifi on during day, off 10-12 hrs each night. Definitely not very efficient for such a large battery.
My 5.0 gives me great battery life listening to mp3's, the radio, podcasts and watching videos I've downloaded to the player.
However, downloading/surfing the internet drains it fast!. Much faster than I expected
I installed Juice Defender yesterday.
23 hours on I'm now getting a reported 85% of battery use consumed by the non-existent cell standby but the good news is that the battery icon is still showing full. Juice Defender in it's default "balanced" setting switches wifi off & on with the screen & it's reasonably quick to reconnect. Definitely worth a try.
Co-incidentally, I also heard back from Samsung this morning who are going to get their service centre to contact me. I'll report back on what they say.
Now on 66 hours with still a near full battery indicated so it looks like Juice Defender is the way to go.

[Q] Wifi vs 3g battery life on Atrix 4g

Hi,
my carrier Three UK only has a 3g network hence so switching off 3g is no possible for me. When at home I always connect to my wifi automatically using a tasker profile and my battery can last over the whole weekend with moderate use. However, when I am out or at work without access to wifi my battery can drain more than 60% in a matter of 10 hours, although I use a Tasker profile which only turns on autosync every hour for just 2 minutes. I could turn of background data completely, but to me that would defeat the point of having apps like gtalk, skype etcv on your phone.
What's your experience of battery life on wifi and 3g?
I have my atrix on Orange UK. I get round about the same battery if i have my phone on 3G and most of the time it says H. I can get much more time on wifi but not the whole weekend because i use it more heavily i guess. Although it also depends what rom your using…stock roms are pretty pathetic on battery life due to blur. I was using joker's cm9 and even though i had 3g on whole day my battery lasted 2 days.

For me, much better battery life on wifi (40-48 hours in weekend on wifi vs 30-36 hours in work days on edge/3G).
When your device is connected to Wi-Fi, then it will consume less battery as it needs less 'juice' to receive data from a Wi-Fi network than a cellular network.
However, if you are on 3G, but have Wi-Fi enabled, then your phone will consume more battery than with Wi-Fi disabled as the phone frequently scans for Wi-Fi networks. The scan time is configurable and stock ROM and CM7 scan every 30 seconds, whereas Neutrino ROM scans every 2 minutes. This means that Neutrino will have slightly better battery with Wi-Fi always enabled as it scans 4x less than normal.
To configure the scan time, you'll have to edit the build.prop.
Regarding your Tasker profile, it's the same thing. Tasker needs to 'detect' when Wi-Fi is on/off and scan for networks in accordance to your personal settings. Therefore it'll still consume battery while it scans and detects.
This brings in the issue of whether it'll be better to use Tasker profiles, or to keep Wi-Fi always enabled and the result will differ for every person depending on the Wi-Fi scan time, or the complications of the Tasker profile.
But putting complications aside, Wi-Fi consumes less battery than 3G, but only when connected.

Power Saver - Try it

I don't know if anyone has tried this yet, but after I have tested it for almost a full work day I can say it's definitely worth using..
Try this: After you completely charge your phone, turn on Power Saver (make sure all options are checked in settings)
Leave it on, don't turn it off, for the entire day.
I had absolutely no slow down.. no problem receiving timely texts/notifications.. the only thing that is a minor annoyance is that screen brightness stays low no matter what, so if you view your screen in full sunlight a lot this will not be for you.. otherwise, HOLY CRAP this makes your phone literally sip power all day.
9 hrs 21 mins 44 secs since I unplugged my phone this morning and I have 63% battery left!
That's roughly 3.96% battery drain per hour!!
This means I will get something like 24-25 hours before I hit zero.. this is with using the phone like normal, where I would normally need to charge after about 16 hours.
Insane. Best battery life I've ever had on a stock phone, and yes I know those monstrosities like the Note 2 can go longer (huge battery..) or if you want to tweak your phone with custom kernels, etc.
But daaaamn I have to say I am impressed.
Leaving Power Saver on from now on!
Btw I should add this is without Wi-Fi, in a LTE area that bounces from LTE to HSPA a lot.. WiFi left on but never connecting to a router

Update. Battery running down a little faster while on my home Wi-Fi watching videos and surfing the net. Don't think I'll make it 24 hours but I am using the phone pretty heavy. I've also noticed that the auto brightness seems to be working overtime whereas it never budged during the day. Tomorrow I'll set my brightness manually to stay at ~30% and turn off the screen option in power saver. See if that yields even better results. So far it appears auto brightness is a power consumer on this phone. We'll see if I'm right tomorrow. I'm at 23% at 14hrs 21mins
Sent from my HTC One using xda premium
I should add that normally I would have charged the phone by now for about two hours since I do most of my heavy usage at night, and when I get home from work I'm already at 20%. But when I've let it run down almost all the way it's been an average of about 15-16 hours
Sent from my HTC One using xda premium
OK so today I kept Power Saver on, but unchecked the "screen" option so that I the screen would adjust as normal to the ambient light conditions. I am finding that the power consumption is essentially the same, very minor change. I now believe that it is Wi-Fi that was causing a quicker drain than LTE/HSPA does, simply because Power Saver does not include an option to cut the Wi-Fi connection when the screen is off.
I will change my Wi-Fi settings to sleep when screen is off and see if that keeps the battery draining at the same slow pace when I am at home connected to my router. I'll try that tonight. If that works successfully, I should get an easy 20 hours + from one charge with normal use (including my evening usage which is heavier usage).
Last night I hit 18 hours and 22 minutes before plugging in at 12% remaining battery without changing the Wi-Fi sleep setting. Hopefully this will be the last test necessary to find the best set up for longer battery life.
Feel free to chime in if anyone else is testing this!
I haven't test the difference between Power Saving and normal. I put Power Saving On in the morning right after a full charge.
I have medium usage for about 20 minutes in the morning using wifi. (It would drop to about 94%). I then turn off wifi and mobile and by 1pm, I have about 82%-88%. I would have about 20 minute usage on mobile data during lunch (flux between 3g, H and rarely LTE). By the time I leave work, it's around 74%. This is when I turn off power saving since I'm usually heading home. Another 20 minutes of medium to heavy usage over H/LTE when on the subway. By the time I get home, it's around 70%. After this, it takes at least about an hour of heavy activity to drain it down to 50% off power saving.
I have the 64 GB Developer Edition and running ARHD 12.1 with the latest T-Mobile Radio.
I've always left power saver on at all times and don't notice any slowdown. One exception is that I don't enable power saver on the screen as it's damn near impossible to see the screen outside. I get pretty damn good battery life on stock rom. Over 3 hrs screen on time in 24 hr period of half mobile data and half wifi.
For enabling and disabling wifi automatically, I use the app wifi matic and it's worked well.

I can easily say the dim screen option is completely unnecessary. Everything is working perfectly, there's no slowdown whatsoever. Even set keep Wi-Fi awake to never. Phone flies, and honestly the data connectivity is ten times better with power saver on. Without it, I would see my phone jump to 2G in a moment of bad coverage and then take FOREVER to reconnect to LTE or HSPA. Now when I unlock my phone it's instantly connected, as if a radio refresh is instant on power saver but laggy as hell without it. I'm very pleased.

Just thinking out loud here...
I don't see how with the data connection off you could have "no problem receiving timely...notifications." What "notifications" are you talking about not missing? Are you saying you actually got cloud-service-based notifications while the phone was sleeping?
Texts/SMS of course would still come in because they don't travel over the data connection, they travel over the voice network.
Email, twitter, etc., they shouldn't get their notifications since that stuff travels over the data connection.
Google Voice users (like me), would miss out on their text messages since those travel over the data connection.
I'll need to test this some. Maybe with the data connection turned off via this setting, the phone actually periodically fires it up to check for notifications, or responds to apps requesting a quick data connection to pull notifications.
UPDATE: Hmmm...turned on power saver, turned on the data disconnect option, put phone to sleep by pressing power button. Waited a minute. Sent myself a google voice # text message and the phone buzzed immediately. Very curious.

I was confused about that same thing. I think it only turns off your data if you havent touched your phone in a while.
If I turn it off, put it down, and pick it up 5 mins later, the data is still connected.
If I turn it off and its in my pocket for an hour, I take it out, the data service is usually trying to reconnect.
I have to admit the way HTC implemented their power saver is impressive. It literally does not delay a single notification. Facebook, Gmail, Hangouts, Scramble with Friends, anything that is set up to notify me works without a hitch. Everything is instant.. compare this to "power saver" mode on the Galaxy line which pretty much cripples the phone.
There is NO reason whatsoever to not have Power Saver turned on with the HTC One. Best implementation ever.
I've had no delays even after not touching the phone for a solid hour. Still get them.

Okay, a little google search reveals the secret behind the data connection magic:
If you want to choose which phone features to conserve power for, tap the Power saver notification first before you turn power saver mode on.
Note: If Data connection is selected, HTC One X automatically disconnects from the mobile network after 15 minutes when it's in sleep mode and the data connection is idle (no download activity, streaming, or data usage). It reconnects and then disconnects periodically when the data connection is idle to save battery power.​
This is from the HTC One X support site, but the same quote is on many of the devices, but oddly not our HTC One. I think it's safe to assume it's the same for our device, whether published or not.

My phone's been untouched for an hour or so, and I just sent it a Google Voice text message. Buzzed instantly, and in light of my above research, it looks like you're correct. I'm certainly going to run with this setting on for a day or two at least for further testing. I only have CPU and data enabled in the settings. My testing the next few days may not be the best, as I'll likely be on wi-fi most of the time, although I could turn wi-fi setting to disconnect wi-fi when sleeping.
I've been using that Qualcomm Snapdragon battery guru app, and Greenify on my phone, so it gets damned good battery all things considered anyways, and I also am not afraid to go on charger during the day, but every little bit helps.
Just a few comments on the power saver:
I've noticed that power saver doesn't disconnect the background data immediately... it does it after a longer interval of non-usage.
Otherwise, it's great. I'm not sure if it's the screen dimming or the underclocking, but it really makes a definite difference in the battery life. I also turn it on for a lot of games (cough, dead space) and it helps keep the phone cooler while gaming.

Not the screen dimming, because I don't use that option.

FYI, it underclocks the CPU so the max is about 1.2ghz; When using Faux Control App, I toggled the Power Saver from the notification and can see it go down to about 1.2 ghz when "On" and when switched off my CPU clock maxes out back to 2ghz.

Yeah I figure that would be the clock speed, but I haven't suffered any loss of performance which is amazing to me.

I can also concur to this fact; since day one of owning this phone I've had power saver on permanently set and I've never experienced performance issues like in other phones, its been smooth, and helpful. The amount of usage I submit my phone to in one day its enough to make any other phone live permanently connected to the charger, and I get at least 1.5 days of juice.
I agree, HTC did a good job with their power saver mode.

6 hrs 23 mins 3 secs since i unplugged it and still have 82% without using PowerSafer. switching between very low LTE and very good hspa all the time and i'm using it quiet often checking facebook, twitter, mails, whatsapp and news.
The only Powersaving App I installed is "Wifi-Matic" wich turns on Wifi only if i'm connected to a specific radio station. Check in to your wlan one time and it will safe the radio stations around. if you aren't connect to this stations it will disable Wifi by itself. Works great for me! (Checking radiostations every 15 mins).
This means for me loosing 2,889% every hour without dimming the screen or something else
Give it a try and compare

How about you try that, with power saver on as well, and report back?
Besides, if you're barely using your phone at all, then yes it will be saving power with sleep mode alone. All I know is I have several friends who move in and out of bad reception/data areas, and now their battery is lasting a whole heck of a lot longer using power saver. It sounds like what you're using is somewhat of a power saver as well.. but you are in a good coverage area too so it's hard to say.
Btw, my figures were with Wifi always on - never switched off, ever.. and I still had greatly extended battery life.

[Q] i9205 battery consumption

Welcome,
I've just bought i9205. Great device, but I'm a bit worried of battery consumption. When I'm using 3g ( LTE/WCDM/GSM ( auto ) mode ), and have energy saver switched to on, device "eats" 1% battery per every 5 minutes !!! I'm not using LTE ( have no this mode in my mobile tarrif plan ).
I've rooted the toy, froze Samsung Push Serivce, get cassie's xtraliterom, switch energy saver off, and on Wifi at home the device "eats" 1% per 7-8 minutes. Haven't tested it on mobile data mode, yet.
Is that normal ?

No It's not normal. Try turning off 3g data to see if this improves. Something downloading in background is a one cause of battery drain. I can read on the browser and wifi with 6 hours screen time and have 35% battery left at the end of the day.
Browsing for the last twenty minutes on wifi and used 1% mobile data and gps are off. I'm no longer using stock rom but it wasn't much different when I was. On standby overnight with everything off mine loses about 1% an hour.
With everything off, in my case, cell standby constantly consumes 12% over and an 8-hour period.
I posted this in another thread too.
What worked for me:
1. WCDMA only - using this depends on whether 3G coverage is good where you're at
2. WiFi ON always - using this depends on whether you need background syncs and are often near WiFi
I use My Battery Drain Analyser to track my drain rate. Link Here
With those two options, my drain rate during sleep is 0.5%/h.
I realize that solution 1 is not for everyone, but try it anyway, but keep tabs on when you lose cell reception entirely to see if this solution is viable for you.
