Hi
I tried searching Google, but get a lot of different answers.
I live in an area with a very bad cellular coverage. I always have 1 out of 5 bars and when I turn mobile data on, it is mainly LTE, but jumps a bit between LTE and Edge and rarely H and H+.
Can that cause a lot of battery drain? As I just factory reset my phone to get rid of every change I did. I enabled Stamina Mode, surfed the web for 15 minutes and my phone was at 95%. Is that normal? Because if my math is right, that shouldn't give me more than 5 hours of screen time, while I heard people getting 8+ without Stamina Mode.
Am I missing something or is their some very needed settings to be changed? Sync off, GPS off, bluetooth, Brightness is as low as possible, NFC off, black background (less power consumption), Wifi off and Wifi constant searching off.
U can easly check urself how cell signal draining battery ,first Check how it is with normal H+/LTE then charg it again for 100% and use ur smartphone with plane mode acivated ,now subtract result from 2 "experiment"
Also of note is that black backgrounds mean diddly on our displays. We aren't on OLEDs.
Also, if you ARE in wifi area it's better to be connected to wifi. Wifi is closer than the cell tower and data disconnects when wifi is connected.
On AMOLED/OLED black background helps because each pixel is individually lit (Black means those pixels are off). In LCDs there is a backlight providing illumination for the entire LCD so as long as your screen is on it won't make a differrence what colors are on your screen.
I'm having a similar issue. I have very low cell reception at work, and I can get maybe 4-5 hours SoT throughout the day and am at 10% when I get home. I've tried uninstalling/disabling apps that use a lot of battery, so hopefully it helps. I'll update if by the end of today I'm able to get 7+ hours SoT (which it seems it's on track to doing).
Edit: For clarification, the apps I've uninstalled that I believed to be using a lot of processing power/ram/battery were Facebook, [Facebook] Messenger, and Words with Friends.

Just use an app like Greenify to block apps running in the background when not in use so you dont havr to uninstall them.
Brightness can have a lot to play on this one. I tend to go with manual brightness so there's no ambient sensors working all the while the display is on, and if you are doing anything where you can cope with lower brightness then drop it.
Keep an eye in battery stats for "google play services" as this can go nuts. When this happens sometimes clearing data can help.
I also found that using google+ to backup my photos caused a lot of battery drain.
I have not found facebook or whatsapp etc to affect my battery much personally. I use stamina mode when i'm out and about to keep the phone at sleep while the screen is off.

At my house I get just enough LTE to cause our S3 to constantly switch to LTE then loose it and switch back to H+. Battery life couldn't make it thru one day. ATT removes the screen that let's you control network mode but I found a backdoor method to lock the phone out of LTE. The phone now stays on H+ and battery life easily jumped 40%. That's the primary reason I held out this time for an unlocked non-ATT-crippled phone--so I can easily turn LTE off.
Well, tried have my phone on over night (for a change to test it).
Everything off (mobile data, gps etc).
Used 7% of my power and every app was closed. When I looked at battery drain, 55% was from cell standby and 40-45% was from Phone Idle.
Tonight I will try charge it to 100% again and then let it be in Flight Mode to see.
I struggled to flatten the battery on my phone the first day 70% of the day with the screen on, no wifi enabled or stamina.
Another test would be to change mobile settings to 3G or 2G to see what difference that makes. Under settings, wireless & networks, select more, mobile networks, then network mode.
I would try the above first before making your phone completely unavailable, especially the 2G.

What is that? H/H+?
GSM - Edge
WCDMA - H/H+
LTE - 4g
But I think 4g uses less power than edge, but it is more than in my area there is 1/5 in 4g coverage, 3-4/5 in H/H+ and 5/5 (always) if using edge.
As I see an better connection gives better batterylife, but 4g uses way less than 3g/edge if same cell signal.
But is going to try it next time I get down to my dad. He got 5/5 in LTE signal. So gonna see if it can stay at 100% over night.

Hehe, ok I understand. But HSPA = 3G. [emoji4] I haven't done any rigorous testing, but I think my stand by times are much better using edge (2G) compared to 3G.

Nope, coverage is about the same. Generally speaking though, 2G > 3G > 4G when it comes to battery life. That's been the rule for years, but as of late, newer radios have become more efficient with 3G and 4G, thus making the difference less noticeable. YMMV. Would be interesting to see your drainage on 3G as well. ☺

From a battery perspective, should I use wifi? Most of the time i'm at home or at work where I have wifi. I also have good lte coverage at both. Speed aside, will I save battery by not using wifi or not?
You'll definitely save battery by using wifi when you can connect. I love the speeds over lte, but it is definitely a hog...
i also had boost of battery using WIFI
Using unlimited data plan makes me to consider using 4g, but I found that Wifi consumes much less battery.
Use wifi. The battery savings are huge.
yes i cant stress enough, wifi saves enormous amounts of battery so use it when ever possible. the difference is like night and day.
Compared to 3G
I've been leaving my wifi off since I have unlimited data and the 3G is pretty fast in my area, no 4G yet.
I've had pretty good battery life lately using only 3G, I'll have to do a few tests and see which one and I'm a fairly heavy user I'm approaching 4GB this month and none of that is tethering
3G or Wifi
Tested watching a streaming video of 22 mins
on 3G I lost 13%
on wifi I lost 8%
Wifi wins, of course standby is probably different, if 3G vs wifi loses this badly I'd have to imagine LTE vs Wifi is a slaughter battery wise
Actually I found something interesting...
For some reason, even when I am home using Wifi, the battery drains faster than I thought. Where I live is like a strange signal spot. If I turn off my WiFi I can see my TBolt constantly switching between LTE and 3G, sometimes it stucks on 1xRTT for a while then goes right back to switching between connections. If I am at work (downtown LA) where the LTE is pretty well covered, I still use WiFi at the office, the battery BARELY drain at ALL.
My theory is that even when WiFi is active, the phone somehow STILL does the LTE/EvDO switching on the background does draining the battery.
If somehow the devs or VZW can tell the phone to STICK to EvDO/1xRTT instead of going back and forth with the LTE while WiFi data is on, it'll solve the problem.
Also just FYI, I have the latest radio and BMAF 1.5 remixed.

pretty much correct. at least on the gsm side, when i connect to wifi at home, i can no longer see if the phone is on 3G or EDGE. but it definitely switches back and forth to those networks, while staying on wifi, you just dont see the icon switching, but its definitely happening. i dont see why cdma and 1x would be any different.
if this is the case then why don't you just turn data off when you are on wifi.

Better yet get juice defender and automate it . Its very good app. Right now it says I'm almost adding fifty percent on to my battery.
I seem to be bucking the trend here, but LTE is working better for me than wifi. I usually have a good signal, so that's part of it.
The other part is that my wifi may be eating more juice than normal because the TB and my router may not be playing nice together. Ever since I added the TB to the network, I've had to reboot the router every coupla days. Before the TB, it was solid weeks on end.
Has anyone who is still having trouble on with batter on wifi set their wifi sleep policy to "Never" sleep? Mine is set to this and if I am home most of the day I will lose very little battery through out the day.
I believe by default the wifi is set to turn off after a period of time or when the screen is off so during this time I believe you are actually reverting back to using the vzw network. To turn wifi to always on go to settings>wireless>wifi settings>hit menu>advanced. The sleep policy is at the top, change sleep policy to never. This my reduce battery while not connected to wifi so I always use the power control widget to turn my wifi off completely while I am away from the house.

Oh yeah this is very important, set wifi sleep policy to never greatly increases battery life. Otherwise it switches back to 3g when screen goes off and drains way more battery. This is very important to set this otherwise you wont see the increase.
Is strongly recommend switching to cdma only if yore gonna use WiFi and plan on saving your battery. Otherwise what's the point. I personally don't even bother using WiFi just use LTE only mode. I'm getting better speeds than most WiFi connections using my LTE.

I've had the HOX for about a week now and I love it but I wish battery life was a bit better. I've gotten to about 50% with only a little over an hour of on screen time.
Here's what my settings are:
Auto-sync off, wifi off, gps off, brightness about 15%, and I'm running CleanROM SE. I do live in a LTE however, possibly that's what's killing my battery? I also have a CPU editor running on battery saver mode.
Any help?

Try keeping WiFi on when your in range. It seems to be better than the cell data for battery life.

In my own experience LTE will chew you battery like nothing. Running apps like battery savers etc... actually doesn't save your battery it kills them faster... as they require process to run in the background... just my own tick on the subject.
Switch LTE off and I'm running on 4G I get around 1mb rate up and down for transfer so that's just as good as high speed internet. I'm not going to complain.
Screen brightness is at 35%
Screen timeout 1min
Wifi on
Data on
All others off
I'll average about 19hrs of battery life. Less if I'm going nuts on it like during weekdays at work.
On the weekend I can get 1day 7hours... ishh.

Remove sense
Auto sync on
Wifi on (if within range)
Force 2g network
Auto brightness
LTE/3G only when absoultey necessary
Bluetooth off unless using
Leave GPS enabled
Download timelines free from the play store and periodically look at it to see if apps are continuously using CPU. Some do and need to be closed constantly. Facebook is an example of that.
I would force 2G also unfortunately that's not an option here in town. It's now either 3G, 4G or LTE 2G networks aren't available anymore... sigh.

Thats too bad because calls and texts sent over 3g consume almost twice as much battery. Time to start using google voice!
Your telling. I tried to get 2G on using the GSM only. I can make calls but there's no more data stream on 2G anymore. GSM band once it seems your attempting to make a data connection switches automaticly to WCDMA Preferred.
I wouldn't expect anything less in a Metro area lol... I guess if I was at the cottage I could bounce off the GSM towers to get my service a 2G lol.

Hey well you know what thats not that bad. Use the 2G to make calls and text and just enable the better radios when you need them for data. This would be the best for battery. Just put the toggles all on switches so you have quick access.
Yes, LTE really destroys the battery. If you are using the phone (i.e. the screen is on), and you are using LTE (e-mail/web/etc.), you won't get more than 2-3 hrs of screentime. Without LTE - or in standby mode (i.e. screen not on) - the phone lasts for a long time, unless you are experience battery drain issues, which some of the LTE users are reporting when signal is lost and regained again.

Hes right! Leave every radio enabled cause you never know when you may need to use them. Also turn brightness up to 100% because the screen looks awesome like that. Then all you have to do is have a giant battery hanging off the phone almost constantly. Perfect trade off if you ask me.
LTE is the biggest killer. With LTE on all the time, I get about 3 hours screen on time (which still blows all other phones that I've had out of the water). If I'm on wifi, I can get around 5 with the same type of use.

How do you turn LTE off? I always have 3 or more bars around my area, so bad reception isn't a problem. I just think the big killer is LTE.
Try the CPU Editor, the link is in my sig. It will definetly help on your battery with the right settings eg., battery saver profile. Read the thread and try it out, let me know what you think.

LTE might be the culprit. I get GREAT battery life on CleanROM, but I'm in an only-HSPA+ area.
Some other basic things you might want to try:
1. Confirm that you aren't in a poor reception area. Your standby times will drop dramatically if your reception is poor for an extended period. If you DO have poor reception, consider flashing a new radio.
2. Look for any wakelocks (times your phone is awake while your screen is off). A few every now and then are good, but if there are a lot, or they are lasting for a long time, it'll also kill your standby time.
3. If you notice unusual wakelocks, use something like BetteryBatteryStats to track down what processe(s) in particular are causing them.

Just disabled LTE. Let's see if my battery can improve now. I'm mostly on Wi-Fi when I'm home anyway.
Keep us posted Winters - I have heard some people have issues with this method - that the 3G connectivity drops a lot. I haven't seen this yet, but haven't tested too much...

I've been working on improving my battery. I've noticed a big improvement by using cpu-editor and super saver app. I've also noticed that battery lasts a lot longer on WiFi than it does on 4g Since 8:30 this morning (7 hours), I've used 33% mostly on WiFi and I think that's pretty good.
So, I was wondering... what can be done to improve battery life when on AT&T? I've tried the new radio, I'm not sire that's made a difference. Maybe it has, hard to tell.

If you're on LTE, you will inevitably use more power than just WiFi, that's just how it works.
If you can kick down to HSPA+ or UMTS you will see significant battery savings.

Thank you for your reply.
I'm in Albany, NY. I've been told we have one LTE tower here, but I've not experienced it yet. I should locate it and drive to it just so I can get a taste of how fast it is.
That said, I use HSPA+, unless I'm on WiFi.

HSPA+ uses more battery than WiFi when actively using it for data, the change just isn't as significant compared to when using the phone on LTE.
Some things you'll want to do to really get battery life savings is to eliminate partial wakelocks, and turn down screen brightness either by using a custom ROM or managing settings manually, as HTC's autobrightness is terrible out of the box and doesn't properly turn down brightness when you need it to, or turn it up when you need it to.
After that, if you don't need to have push email all the time then you can turn off always on mobile data, or manually turn off mobile data when you aren't using it.
Our Russian LTE testers of HTC One XL reports about 1.5-2 hours of LTE tethering. Make your conclusions.

Can someone explain to me how to go from LTE to HSPA+ to EDGE? I've tried looking in the settings but all I can find is a "Mobile network" on/off toggle. There is no option to turn on/off LTE, or HSPA+ or EDGE. It's a bit frustrating. Then in my status bar, the 4G icon is always displayed even when "Mobile network" is off. No data but it still shows up. Is this how it is supposed to be?
BTW, I'm using the stock ROM with Apex Launcher. I do not want to root or use a custom ROM.

Yes, in my experience with the S4 it's a pretty big difference UNLESS you get a very strong LTE signal. I'm on tmobile and now have the N5 and use the 3G setting which is HSPA/+ Plenty fast for me for what I do. When I want some extra speed I'll kick on the LTE
Does anyone have a more detailed answer for this? I just got this phone yesterday so I haven't been able to find out myself yet, just with 5hour battery life from 100% to 4% on what will only be half of its normal day I'm looking for anything to help right now till I get a battery case. This phone is one of only two to have a LTE radio that is supposed to use 30% less power than usual so I'm wondering if that makes it as efficient if not more than 3G for idle in your pocket to light stuff like FlipBoard.
it would depend on the quality of the data connection. im in brooklyn nyc, and use lte on my nexus 5 exclusively, used to use it on my nexus 4 as well. with 3g(hspa+), on both my n5 and n4, i average about 4-4.5 hours screen on time. when using lte, i average about 5-6 hours screen on time on both my nexus 5 and 4. after noticing this difference, i use exclusively lte on both my devices, as i average an hour more screen on time when using exclusively lte.

This phone is one of only two to have a LTE radio that is supposed to use 30% less power than usual so I'm wondering if that makes it as efficient if not more than 3G for idle in your pocket to light stuff like FlipBoard.

Serious battery drain can have many reasons. One is having LTE on, syncing on(if you just booted it up, and input your Google account and let all your apps sync and download, its gonna drain your battery fast the first time), having locations on and wifi enabled. If you are in an area with poor reception, your phone will drain more trying to find connection.

it would depend on the quality of the data connection. im in brooklyn nyc, and use lte on my nexus 5 exclusively, used to use it on my nexus 4 as well. with 3g(hspa+), on both my n5 and n4, i average about 4-4.5 hours screen on time. when using lte, i average about 5-6 hours screen on time on both my nexus 5 and 4. after noticing this difference, i use exclusively lte on both my devices, as i average an hour more screen on time when using exclusively lte.

Thanks for the information. That's what I was wondering but I couldn't find anyone that had already tested this with these new radios. If I get the time this weekend maybe I'll do my own test in detail to compare LTE to 3G. Am thinking of using a TV episode on Netflix and see which makes the battery drop faster over the 30 or so minutes.
Slightly off topic, does anyone's WiFi show as always on in the battery monitor even if its been off? Still trying to figure out my battery drain issue, if it even is an issue with just me, I bought this phone knowing it had a small battery.

go to the main phone settings, wifi, 3 dots on the bottom right, advanced, then disable scanning always available..
ill be interested in seeing your results

Seems that's a whole other debate on weather leaving that on or turning it off helps battery life. Apparently if you turn it off then apps that want your location will turn the GPS on and waste battery (looking at you Facebook...), but if you leave it on the phone just tells the app your location from WiFi networks around you.
One thing I didn't think about is I had added my work WiFi yesterday but it wouldn't connect to it, wouldn't tell me why but I'm assuming it's because of bad signal as I'm a valet outside and the WiFi is from a bar across the street so I forgot about it but WiFi was left on with that network saved, my Nexus 7 can connect to it on most days and any laptop has no issues but with this being a phone I guess it doesn't have a big enough antenna. So I'm wondering if now that I deleted that WiFi network, and I always have my phone set to not notify me of public networks, if my battery won't die so fast today.
And now I'm just rambling but I just looked at my screenshot I took yesterday of battery use before plugging in at 4% and WiFi isn't even being shown on top six things that used the battery, lowest one being shown is a Chrome process using 3%.
EDIT: Well off to work now with my phone 100% charged, will have screen 100% (am outside in the sun), BT off, WiFi on (disconnected, no saved networks nearby, open network notifications off, always on during sleep, scanning always available, avoid poor connections, and WiFi optimization), LTE on/connected, NFC off. So lets see how things go. It will have tons of screen on time as all I do at work is read through FlipBoard, then if I run out of things on there I move to FB. Lets see how this goes...

Nexus 5 has it and its doing its job saving battery
Sorry for digging up such an old thread, but with LTE my Nexus 6P, it switches between HSPA and 3G. When turned to 3G, nothing changes. Would that mean I would save battery?

Hello,
I recently picked up a OP6 and I'm really pleased with it overall but SOT has been a little disappointing. At least I think it has depending which battery app I consult!
Accubattery Pro thinks I'm getting an average 8h 16m of SOT (this is definitely not correct!).
GSM Battery Monitor PRO reckons 4h 46m of SOT (which still seems a bit high).
In the battery tab of the Settings menu it reckons having used 65% of my battery I've had 2h 50m SOT (ie. from 100% after 2hr 50m of SOT I'm now sitting on 35%). I think this equates to about 4h 30m of SOT if I continued at the same pace. I guess this tallies pretty closely to the GSM Battery Monitor PRO so maybe this is about accurate.
I've followed the guide here to get the most SOT but 4h 30m seems on the low given that I don't game or stream, don't have FB installed etc. This is purely webbrowsing, a bit of YT and a podcast app (listening to downloaded podcasts rather than streamed if that makes a difference).
Nothing in the battery stats seems that unusual (please see attached). What does seem a little odd is that I'm not in a great spot for mobile reception but looking at the stats it doesn't look like the radio is draining the battery.
Any advice on how to delve deeper? I'm 100% stock and not rooted.
Any advice for a OP newbie is much appreciated
Hmmmm Better Battery Stats seems to tell a rather different story especially around the radio reception.
Again any advice much appreciated!
The poor signal is killing you. When the signal is poor it pumps out more juice trying to stay connected. If you will be in an area with poor signal and won't be using your phone I suggest putting it in airplane mode or maybe setting it to 3G as a proof of concept. If your battery is much better then you found your issue
Also wifi scanning is turned on,which is a battery killer. Turn it off and you can see a great difference

Thanks Spartan! The problem is poor indoor reception with the signal constantly cutting in and out. As such airplane mode may be the ultimate option but obviously it's a bit of a bummer as a long term solution! I'm going to try another provider which claims to have better indoor coverage in my area.
Question #1 - you mention trying setting to 3G as a proof of concept. Is that because a 2G/3G uses less power to connect than searching for a 4G connection? Should I try the 2G only option before the 3G one?
Question #2 - if I do try 2G/3G (before trying airplane mode) should I turn off mobile data too or does that make a difference?
Question #3 - I'm guessing having 2 sims installed makes the problem even worse as both are constantly calling for signal? I typically use one for data and one for voice.
Question #4 - when some folks post their battery graphs they have a picture which shows the mobile and wifi signal (see attached as an example). I don't seem to be able to find this. Was it removed from the latest update as the battery section seems to have changed a bit.
Thanks again!

Thanks for taking the time to reply!
Strangely I don't think I do have wifi scanning on (please see attached screenshots)! Location services are also off.
Are you thinking I do because the wifi is on 100% of the time?
Could this be because an app is somehow keeping it awake?
Hmmm can't see an option to check if "keep wifi on during sleep" is enabled. Has this been removed from 9.0.2?
