How to disable HSPA / HSDPA for better battery life - Nexus 4 General

Hi,
I was wondering if we can turn off hsdpa to save battery life, i used to have a Captivate and we used this secret menú to disable hsdpa, leaving only the 3G which consume less battery than Hdspa and is faster than 2G, but i can not find this menú on my nexus 4, someone knows how to do it?
This is the link to Samsung Galaxy where they shows how to do it:

[REF] WORKING: How to disable HSPA / HSDPA for better battery life
Hi people.
One way to get longer battery life is to disable HSPA and just use 3G. 3G (UMTS) is not as slow as EDGE/GPRS but doesn't use as much power as HSPA.
Here's a quick comparison of *typical* download speeds:
GPRS: 48 kbit/s, EDGE: 150-200 kbit/s, 3G: 384 kbit/s, HSDPA: 1000 kbit/s
After some searching, I've found a method that actually works for our Galaxy S:
Go to the phone dialer pad and enter this code: *#301279#
Click [2] CHANGE HSPA REVISION
Click [1] RELEASE 99 (HSPA OFF)
Then you should see something like:
CHANGE_R99
HSDPA OFF, HSUPA OFF
Done!
Press the BACK button to exit, or press MENU button then END.
The setting should take effect shortly after you exit the menu. To be sure that the setting take effect, toggle Flight/Airplane mode.
You could store that number in your phone book or speed dial for a quick way to toggle HSPA.
The setting STAYS ACROSS REBOOTS!
If you want to enable HSPA again just go back to the same menu and choose [3] RELEASE 6 (HSDPA/HSUPA).
Just tested it with the XXJPP radio and it really works.
Longer battery life at last!

Quick way is Settings-More-Mobile Networks- Use Only 2g.
Better way is to install a toggle control app that let's you do it in one touch.

Thx, But 2G Its too slow, with this method the Hsdpa is off but the 3G still working so Its faster, but Looks like lg doesnt have this option or i can not find it.... Jet

HSPA is 3g
Sent from my Nexus 4 using xda app-developers app

Try this code:
*#*#4636#*#* :good:

Yeah the main way is to check "use 2g only" which would give you edge only and may save battery but yes it is very slow.
There is also a toggle 2g app which makes it more convenient, or you can use tasker.
Based on what I've read on the forums I'm pretty sure HSPA is 3g. In which case theres no in between.. if you go through the dialer menu you can choose wcdma/gsm which is 3g/2g. We're used to thinking hspa is 4g but its actually 3g since true 4g is actually LTE. Confusing, I know.
Please correct me if I'm wrong.

HSPA/HSDPA is enhanced 3G. Sometimes referred to as 3G+. It is faster than 3G, but not near as fast as LTE, which is true 4G. I speak mainly for the AT&T network because I spent a lot a time with this on my HTC Inspire. AT&T invested a bit of money enhancing their backhaul to accommodate HSPA. I lived in a marginal area where my Inspire was typically on 3G but, by design of the device, was constantly searching and switching to HSPA and back and forth. This constantly drained my battery and caused dropped calls because it was switching towers when doing this. I ended up having to place a microcell in my home to alleviate this, since there was no way to do it thru the device. I'm not sure how my N4 would act today because I still use that microcell.

The OP was asking how to turn off HSPA. In the context of this phone, that's 3G. The next step down is Edge.

HSDPA has no more battery drain than 3G...

3G is not HSDPA, is UMTS. HSDPA is 3G+.

True that. Considering this is considered a developers phone that is unlocked and unbranded, I'm a bit surprised at the limited band selection.

It's a 5 band GSM phone, what more would you want? Other than LTE, obviously, we've done THAT discussion to death
Sent from my Nexus 4 using xda app-developers app

I was referring to the ability to select the bands. When I go into the hidden test menu and try to select a radio band, I get a message that states "Unfortunately, the process com.android.phone has stopped". And yes I know this was done intentionally to hide the LTE band. My point was that I consider that somewhat odd. That is all. With previous phones I found the ability to switch bands useful for signal tests in my area, even though I couldn't always make them stick.

THANK YOU. I can finally enjoy fast (Fast enough for my needs) internet without the blackhole drain of HSPA+. 3g, UMTS, does not drain as much as HSPA+.

It's probably an NV Item in the Qualcomm radio. You would just need to find what value it needs, put the N4 into "modem" mode, and use NV Item editor or similar to change the value.

turn the data and gps off ,.turn down screen brightness, then you will found very long battery life for you

Suddenly no 3g, always H?!

My carrier had some little problems during the past weeks, aparently they were working on something. I sometimes, for short periods, did not have data connection or no servic at all. Now the problems are gone and a speedtest today showed that at my home, the download speed went from an average 1 Mbit to over 5 Mbit!
However, the H symbol won't go away anymore! It used to switch to 3g when not data was transferred. I assume that this will influence battery life.
Is there anything I should be worried?
From what I recall, H is faster than 3g, as long as your in a good signal area, the H will always be visable, it will only drop down to 3g if the area your in has no H signal... and if there is no 3g it will drop to a 2g signal... simples, having the H does not meen that data is being transfered!
I am aware of the different speed levels, what I experience now is that the H symbol stays all the time, whereas it used to change to 3g when idling even in areas with very good reception...

Wait, I don't get what you're saying. Let me clear it up:
Very good reception = H
Not so good reception = 3G
You want to see H (means HSDPA which is a a type of 3G data, but it's faster).

Okay, I'll try that too!
I live in an area with very good reception and therefore the phone used to switch from 3g to H whenever data was transfered and back . Now, however, it stays on H all the time and does not switch back to 3g when no traffic occurs.
It is just a change in the pattern my phone behaves so I wanted to get some info on that...
Hi, it's your phone doing what it should by seeking the best signal.
H refers to HSDPA which is based on UMTS (3G). Consider it a 'turbo' version of 3G. It's sometimes also referred to as 3G+ because it's faster then 3G but not really 4G technology. The tower in your area most likely got upgraded to HSDPA that's why you don't see the 3G icon anymore.

Not correct, he mentioned that his phone was using H on demand before, so the capability was there already.
The problem is that H mode uses more battery than 3G, which is why it normally only switches to H during data transfers instead of continously being on.
Possibly your provider made a change which forces your phone to stay in H mode. On hardcores homepage (see speedmod kernel thread) he describes a method to manually deactivate H mode if you want to play with it.
Hope that helps.

seems to be the explanation... Suddenly I have ~6 Mbit, so almost unsurprisingly there had to be a catch
as for disabling H, it would be permanently so not quite an option. I guess, I'll have to live with it but nevertheless I'll call customer support..
Hspa and 3g are actually different technologies, but can be used on the same site and freq. If you have noticed that your phone is nowdays all the time showing H ( hspa ) and not in 3g like before it means that your carrier has expanded their hspa features and capacity of the network on that area. Main difference between these two tech is of course the speed and how network resources are shared between the users. In 3g you have dedicated ones, but speed limited and in hspa you are sharing the resources between other ones under that cell area. hspa is good if you are near by the cell and there is not too many users from battery consumption point of aswell from througput point of view, 3g is better if you are on the cell edge due to dedicated resources reserved only for you. Main point is, battery consumption of your phone depends mainly how you use your phone ,what kind of applications you have and how often those are connecting/contacted by the network.
Browsing in 3g sucks!

[Q] How to lock network mode to HSPA+ insdead of 3G?

As title, how do i do it in galaxy note?
hspa+ is 3G
HSPA bearers are assigned on demand. WHEN your data connection is idle it will show 3G, if in 3G service area. This is normal
Sent from my GT-N7000 using xda premium
Maybe the icon is misleading.
Because when the connection is idel, the icon shows 3G. When is busy, H+.
I just want my phone to stay on H+, because it takes 3-5 seconds to connect.
HTC phones have this stay alive option as i know.
I have this issue. The data on all my modern devices always worked MUCH better when it showed H as opposed to 3G. Why is this?
I can do this on my wife's Android phone, so I know it is an option. Hopefully the feature hasn't been removed on the Note - I will soon be moving from my trusty HTC Advantage (the first phone with a 5 inch screen) and always lock my phones to H+.
As far as I'm aware, H is faster than 3g. So that's why your internet will work faster when H is shown. Also the H signal is not available in all areas....at least it's not in the UK. If H is not available the 3g symbol will show. If 3g isn't available then G will show up, which is even slower. I've noticed H is only fully available in Towns or cities or surrounding nearby country side.
So you can't set it to always connect to H because it's not always available.

New York City has pretty good coverage if you're on AT&T and you haven't been flagged in some way by them. According to their coverage map on their website it's solid "faux" G all around my home.
According to http://forum.xda-developers.com/showthread.php?t=1380284 there is a menu which is accessed by entering in *#9900# on the keypads. This menu gives you the option to disable fast dormancy, which according to http://forum.xda-developers.com/showthread.php?t=1111581 will change the timeout from H+ to 3G from 7 seconds to 30 seconds. Admittedly it's not the permanent lock to H+ that was originally requested, but from what I read it sounds like it is done as a battery saving preventative measure.

build.prop

Can somebody be so kind and upload stock buid.prop for Bell AHD?
Wanna see differences between the AT&T and Bell setup - looking for way to enable network type switch in phone info
Thanks
here you go!
please extract it to get the build.prop for a bell AHD
Well, I tried replacing build.prop in hope that will enable band switch but it did not
I would really like to have option enabled in settings or trough phone info.
In phone info i can switch between LTE/GSM/WCDMA and LTE/CDMA/EvDO/GSM/WCDMA.
Any other choice reverts back to LTE/GSM/WCDMA. I have done EB40 battery mod and I am not worried about battery life as I can pull out 2.5 days on medium usage but 70% of my day I do not need LTE so I was hoping to extend battery life even more by switching to EDGE

I dont know what ATT did...
I followed instructions from here: http://forum.xda-developers.com/showthread.php?t=1386383 and I got network switch enabled in settings but when I select GSM only setting does not stick...Reverts back to LTE.
I tried adding ATT 3g APN (wap.cingular) but it wont connect to the data network at all???
Really stuck now.
Generaly I always used 2g data connection when I am at work as I still can get my emails and mms and do some basic browsing and internet radio streaming. Then if I stream videos or download apps or upload large amount of pics I would switch to 3g (LTE in this case)
I wonder does it have anything to do with account provisoning for LTE???
I really would like to have that option enabled and working. I know ATT is in the process of phasing out 2G data on account of LTE but as long as it is available I would like to use it...
After completing the steps in that post and deleting the backups change the operator to maritime. Successfully dropped down to 2G /EDGE. Thanks for this thread. Was hoping someone would post a bit of information on it. Here's some screenshots.

Maritime is another AT&T network. It was actually the default on my Atrix 4G. Sadly, the Atrix HD doesn't display the code for each maritime network. Shouldn't be to hard to switch the default to it if we knew which code it was. Setting the default to Maritime wouldn't help considering there's 3.
Sent from my Motorola Atrix HD MAXX
Very interesting. If set to 3G only on Maritime it displays the 4G without LTE. Through Phone Info, it shows that I'm connected through HSPA as well. Selecting Automatic sticks with HSPA unless I get better LTE service. Seems like 3G is a good balance between speed and battery life.

Is there any proof that disabling LTE saves battery life? In older phones, disabling 3G would save battery life because there were separate chip-sets for 2G and 3G services. That isn't the case now, a single chipset handles all signaling. Thus, there are no chips that are powered down when 4G is disabled. I would expect battery savings to be minimal.
Additionally, because of the increase efficiency of the LTE network (combined with less network loading), your phone will have an open data connection for a much shorter time, when transmitting data.
I've got my AHD on the AT&T network using a StraightTalk AT&T sim. $45.00 unlimited everything. With the APN that straight talk uses, it never searches for LTE. Just on 4g all day long, with no LTE searching at all.

Disable 4g for good? Possible at all?

Hi folks
Today I got my i9305 (swapped for i9300).
I'm not interested at all in 4G, it's the 2GB ram i was craving for. Anyways, is it possible to disable 4g completely?
I read 3G and 4G both use the same chip/antenna and therefore disabling 4g is not possible without killing 3g too. Is that true? Would be a bit of a bummer but in the end I stick to edge anyways and fire 3g/4g only up when really needed and disable it asap.
Also, I read the new 3g/4g chip is more energy hungry than the 3g-only chip, even if only 3g networks are selected.
Can someone elaborate on this?
I dont think there is a big difference in battery performance
You can choose WCDMA only on the mobile network options and 4G will be off. I'm not sure if 2G will be off too, though.
Perseus Kernel has some lte energy tweaks.

WCDMA is 3G only. GSM is 2G. The S3 is really missing a setting for WCDMA/GSM only.. this would effectively block 4G and only allow 2G, 3G, HSDPA and HSUPA. I don't need 4G, even for normal browsing HSDPA is pretty fast. Would love the WCDMA/GSM option!

cool, thanks for the hint. But I wonder, does this disable the 4G modem? I think what it does is tell the phone to ignore 4g signals in favor of 3g, but the 4g module is still on (and thus consuming power).
If the 3g and 4g modems are actually on the same chip, we're phucked :silly: I believe this is the case, but I still need someone to confirm this...
afaik 4G will only be active if your contract/the area you are in supports it.
Same scenario for 2G/3G. If your phone is on 3G it will not be using 2G at the same time. Unless you are actually on 4G your 4G is NOT active. I can easily see this as I have both the 9300 and 9305 on which I get very similar battery performance (rom dependant of course). If 4G was active then this would not be the case.
Yes LTE is power hungry but only if you are using it!!!
Point is I notice NO difference between the phones battery so do not overthink the situation and just enjoy the phone.
EDIT: Check this out, will have to see if it actually makes any difference in battery preformance though!

Alright, thanks for your input. I'll take your word for it I just got i9305 yesterday (switched from i9300). I have yet to evaluate the battery behaviour. The WCDMA/GSM Auto option you linked to sure is a must have!
I have Korean Galaxy S3 with 2GB RAM.......from the dial pad i can enter a code and go to hidden settings menu....there i can select gsm/wcdma/lte only options.......... as I don't have a LTE connection but my operator and phone supports it.....in the beginning i got network error messages....although the network connection was always stable and i wasn't disconnected......
so what i guessed from this was that LTE modem was on and even i was connected to 3g it searched for lte and then got rejected by operator and gave error...
so i went to hidden menu and selected "WCDMA only" and now i don't get that error and always connected on 3g.....
from this i conclude that it has stopped searching for LTE connection but is the modem actually turned off.....i don't know...
maybe you can make some sense of this....
Just use a 3G sim.
I've got the LTE, and am using my previous 3G sim on a 3G plan.
You can switch off LTE by installing and app called "Phone Info" from the Play Store.
And under device info set network selection to "WCDMA Preferred". This is essentially the WCDMA/GSM option you're looking for.
I did that and my battery life is much better.

Yip PhoneInfo works well. You can use WCDMA preferred (this will prefer 3G/HSDPA over 2G) or GSM/CDMA PRL auto (this will go with the stronger signal)

Do you have a 4G sim/contract as I can only see this being of benefit if you can actually use 4G or if your network supports it and it tries to connect via 4G before realising your contract does not support 4G. Otherwise it will not use 4G anyway. As I mentioned above I can easily see this as I have both the 9300 and 9305.
I do not have time at the moment but will try next week and see if it actually makes any difference to battery life. Would be nice if it does!
Yeah, I have LTE provisioned on my contract, there's nothing special about the sim though. To be honest I have no idea if the phone will try to attach on LTE and then just fail in the case that you don't have LTE provisioned and as a result use more battery?

Guess only some good old tests will tell us but as I do not really notice any difference in battery life between the 9300 and 9305 (I do not have an LTE contract) I am not holding my breath though but hope to be pleasantly surprised!
This will information not be of much use but anyways:
I was abroad for 4 days and thus had mobile data connection turned off, only using regular cell phone connectivitgy for calls/sms and wifi in between.
The battery life was downright amazing, never managed to get it below 50% for an entire day, even when taking pictures, using wifi + whatsapp and doing calls all the time. I even did play games in between.
No surprise, but still, when mobile data is off and you rely solely on wifi, bettry life is outstanding :good:

Your not ON LTE 24/7 it automatically picks up LTE when needed and Only if you are using the internet. I use the internet the same as the I9300 and I still had to charge my phone every night just like the I9305. I have all widgets that need Network connection and I Always have it set on auto 4g/3g/2g . 100% there is no difference at all. If I use powersaving mode and use my phone on occassion i can have it last almost 2 full days even with LTE set this is with stock kernel. And this is the same i had with the I9300 on stock rom.
But i always use the phone OC at 1700 No undervolt Always have lte on auto. And I using perseus Kenerl and i charge my phone before i sleep. Which is what i did with the I9300 when i had it OC
All this talk about dramatic battery drain.. I dont see it
So is there a problem with battery drain or not ?

Force HSPA+ instead of 4G?

Does anyone know how to force the note 4 to use HSPA+ instead of 4G?
The reason why i ask is because in areas where i cannot get 4GLTE the note 4 goes into 4G and its basically unusable (~1mbps maybe, most of the time i cannot even perform a speed test) eventhough the 4G is with 5 bars. In the same exact area HSPA+ gets very good speeds of 6mbp+
To test this, i forced 4G on my note 4 at my house and got a 1mbps speed test. Before upgrading to the note 4 from t-mobile i had an old note 2 from verizon running H+ getting 6mbps+ at my home.
Update: i really think the note 4 or the modem is causing the issue. Testing again my my house. When i first force the 4G connection the speed test are horrible. (< 1 mbps). After some time it seems idling in 4G it seems i got pushed into H+ reframed?(but still 4g icon) and getting consistance 6mbps.
I also noticed that the note 4 drops LTE to 4G at 2 bars or so when LTE speeds is definitely present and running at 20mbps
Hspa+ shows as 4g. If you go to other network settings where the apn is you can select lte,wcdma, options. In remote areas my 4g speed is better than my lte . The lingo is kinda weird so every carrier has different definitions of 4g. Hspa+ is technically 3.5g lol.
The app Advanced Signal Status let's you choose your network type.
Install it from play store and lock it to what you want. Try phone calls and SMS for the modes you try because some modes will be data only.
I noticed this today at home. I forced it to WCDMA mode only, it took like 10 mins for it to eventually show "4G" at my home office. The signal and download speed were terrible when forced into WCDMA hspa mode+ (4G) . In the same room and home my Note 3 would get a very good signal this time last year when I used the Note 3.
Perhaps T mobile has done something to the cell site here? Or The Note 4 isnt working as it should?
Ive had the same issue. So i work in one city and live in another. So when i get to work my data is slooooow. I force it to 4g and after a while back to lte. Speeds are fine. Same thing happens when i get home. Tmo told me to just restart my phone but that doesnt always work
Same situation with me. LTE tower doesn't reach my room but I got 10mbps in my living room....and my room I get less than 1mbps and goes to lte to 4g often with very slow speeds. I even have a LTE booster which doesn't really help much with speed. Without the lte booster I get almost 0 signal in my room
I used to have same problem during lte upgrade in my area. On lte around 8+ up and down while on 4g speds were 15-20 down and less than 2 up. Ping times were longer on 4g. After upgrade I no longer need to switch between lte and 4g

But is T Mobile removing their 4G HSPA wcdma towers? I used to get a very good db signal in my office, now -115db at best for 4G in same location but band 4 700Mhz is now present? Any relationship between these ...
See the below screen shot. On that menu you can pick the non LTE function and force H+. You can also switch back to LTE.

Thanks I had already figured out how to.force a specific data connection , hence why that thread I posted was asking what the default option is, since I didn't write it down.
But back on subject, 4G next to non existent now at home after 700mhz band 12 availability.

What is UMTS? I never get Hspa+
I've found that my data is ridiculously slow (I'm talking edge speeds) when I turn WiFi off, even when I am in an area that gets a strong LTE signal. I feel like my device does not automatically connect to the best available tower; rather, it seems to try to latch on to whatever tower it was connected to before I connected to WiFi. Toggling "mobile data" off then on again seems to reconnect my device to the closer/better tower and the speed improves drastically. (It's possible that toggling airplane mode or network modes will do the same thing). When you are in an area that has poor LTE, you might consider keeping it off. Change the selection from “LTE/WCDMA/GSM” to just “WCDMA/GSM” and you'll be on the slower HSPA+ network (though, I believe it still shows the 4G icon). You can always change it back when you are in a better area.
4G is back up and running in my home location. Must have been temp disabled when they rolled out 700mhz band 12 LTE in my area.
