Hey, I've got a (rooted) G1 on T-Mo contract.
I want to check if I'm getting the fastest internet I possibly can. I know Haykuro's build display an 'H' instead of 3G if you're on HSDPA, but I'm using JesusFreke's latest cupcake build and it's my understanding that that doesn't.
So the question is, how can I check whether I'm getting real super wow omg 3.5G internet (which presumably I can, living right in central London) or just the regular 3G?
I've wouldn't normally think twice, but I've read lots online about having to enable it and there seems to be a lot of confusion. Also, it would be nice to know when I'm on 3G and when i'm on HSPDA, given that JF's build (kickass as it is) doesn't include an icon for it.

download xtremelabs speed test from the market. then check your max speed against max 3g and min hsdpa speeds that you have since googled to find out. while on haykuros rom, i got the h icon and i have full 3g coverage here in kansas city kansas.
Ilm in the same boat at the moment. When running Haykuro's H build I have H on Orange UK, the about status of the network says Ilm running on HSDPA but nettraffic says I have no connection speed unlike UMTS (won't work in other words).
I'm currently on JF's ADP1.5 rom based on htc build and only get UMTS. It would be nice to be able to have HSDPA but UMTS is fine...
Hey aad4231, thanks for your reply...
I'm a little confused, I thought UMTS utilised 3.0g services whereas HSDPA uses 3.5g? When using JF, T-Mobile or Haykuro's G build the phone uses UMTS according to system information and netmeter and nettraffic. When I use Haykuro's H Build GPRS comes up, then UMTS and finally HSDPA. Data services work while on GPRS / UMTS but as soon as HSDPA comes up there is no connection speed in system info.
I'd love to have HSDPA speeds (with Orange UK I believe it's 3.6mbps or smthg) rather than UMTS as I use my G1 as a mobile router with Wifi-Tether.
Thanks in advance again!
Run a speedtest (e.g. http://i.dslr.net/tinyspeedtest.html). If your downlink is greater than 384kbps, then you have HSDPA.
As been mentioned above, just because you do not have a H icon doesn't mean you are not connected via HSDPA. The H icon is present only in Haykuro HTC build because HTC added extra icons to indicate whether a 3G connection is HSXPA enabled or not. However, that does not mean that standard Dream software cannot connect via HSDPA. It does, but it will not indicate it. Again, confirm with speed test.
Just done a speed test using Xtremelabs speedtest from market. I noticed I'm now getting 843.5kbps since I flashed my G1 with JF's ADP1.5 last night. Prior to this I was only getting about 320kbps on JF's RC9/RC33 Builds.
Thanks for your quick reply and sorry for having to get you to explain again.

Thats pretty impressive, but as far as I know the different versions flash don't effect the speed. I believe that has all to do with the radio. Did you update your radio, that may have something to do with the increased speeds?

Actually the most likely scenario is just moment-to-moment variation in network usage. Packet-switched data services are usually delivered on a "best effort" basis. If you check the bandwidth at different times of day you will probably notice fluctuating numbers.

Yeah, Flashed the Radio with HTC's 1.5 from their Dream website. I do notice that speeds vary though throughout the day. In Mid-day I get about 400mbps but hadn't got 800mbps+ before, even in the evening.
Hot damn, it must be a low traffic day here in AZ. I just pulled down 1062kbits/s.
I just noticed that it says your network type on Settings>About>Status, so you can get an easy definitive answer rather than just running a speed test. Also has battery level which is nice. I made a homepage link to it on anycut for easy access
I'm kind of confused. After flashing cyan's rom, my service keeps switching between 3g and H. This has not happened prior to me flashing the rom though. What is H? Is it a fixable problem?
Could be wrong, but it's probably H for HSDPA
Oooh its actually a bonus for me at least, since before, my Nexus showed 3G whther it was connected to the faster HSDPA or to 3G (Unlike my Hero, which showed H or 3G)
will have to give CM Rom a go once my Nexus arrives back from HTC
Dayz
Cyanogen's ROM enabled the notification if you are on HSPA network. I beleive you will get 3G if your network changes to UMTS (depends on your location). The stock ROM shows 3G even if you are on the HSPA network.
Ohhhh alright. I understand then. It still bugs me though lol
Yes i can verify this is the case, reason why i jumped ship to cynogens rom

since by default the phone is after the fastest avail option, it tries to get to 3G. if and when you are in the area with uncertain 3G coverage, it could scan and switch to 3G, then to HSDPA (hence - H) or even EDGE (E)
I have this mess on the stock N1 - 3G-H-E changing constantly in some areas.
bad thing is that in such case my data stalls:-( I guess it has nada to do with Cyan's ROM. fwiw
No he must have done something, normally Nexus only shows 3G even if there's HSDPA.
I have HSDPA and here with Stock ROM it only shows 3G, but you can see in the Settings at Status that you've got HSDPA.

Actually, HSDPA is faster than "3G" (which I'm assuming is actually UMTS), so your phone will use HSDPA whenever it can, then downgrade to 3G if HSDPA isn't available, then EDGE, then GPRS. HSDPA is actually considered "3.5G, 3G+ or turbo 3G" according to its Wikipedia entry.

He did do something. Someone already asked him on Twitter and he answered here.
This reminds me of my times with Windows Mobile where you'd change a registry setting to make the indicator show you had an EDGE connection instead of always showing G (for GPRS)
Quite nice, I was missing this on Nexus

did you even read what I wrote? The stock ROM has the H icon but for some reason its disabled so that only the 3G icon shows up if you have HSPA. Cyanogen simply enabled the H icon to be usable.
I wonder why though, they would disable it...
I cant think of any solid reasons, and if it is in-fact better then "3G", You would think they would want people to know that they have a faster connection present..
but anyways, thanks cyanogen

Given the confusion in this thread alone, which is presumably made up of people who know more about their phones than the general public, I think it's reasonably obvious why it's disabled. The phone companies have spent lots of money and time marketing "3G" to the public - most people will know what you're talking about if you say 3G, almost none of them will know what HSDPA is, and I doubt the cell phone company wants to spend the time to explain that it's actually better than standard 3G to every customer. It's just that much easier to make it say "3G" and be done with it.
ISTR that my Hero and Touch Diamond2 before that, and Touch Cruise before that, all showed a 3G symbol on hsdpa until you were actually downloading something - then it changed to show a H before returning to a 3G when stopped downloading.
I think!

@ melterx12
My Post was regarding this, it can't be that has H in display with stock ROM
So, this 'H' HSDPA signal display should be a fix in the OTA update?
Is there a possibility that someone answer here and explain how to enable H icon showing?
I think it's in framework-res.apk but don't know where exactly...
I don't want to install a cyanogenmod rom or others to have it. Who have already done it, could share that information with us...this is a forum..

I want to enable the H icon on the stock ROM.
Rooted phone, custom recovery, locked bootloader.
Is this possible?

I've installed a couple of the CM 5 ROMS based on the threads that say works on Fender. However, I am having the worst time with 3G. Downloading from the market is painfully slow and many apps will not work, because they rely on a 3G signal. For example, T-Mobile Visual Voicemail will not load. I cannot find a fix. Is anyone else experiencing this problem? Any solutions? CM 5.07 test 2.
I am noticing the same thing. I also can't access the apn list. It just gives me an error.
So frustrating. The ROM is great, but without 3G, it's worthless. And I can't search for networks either.
Yep that the exact same feeling here.
I think I might have a solution. Type this in to the dialer *#*#4636#*#* then go to phone information and then scroll down to were it says "set preferred network type" then select wcdma only. Let it drop the radio connection then it should connect to 3g. After that you should be able to reset it to wcdma preferred. This fixed my 3g.
My 3G works fine for me. But it shows as HSPDA instead.
Thats what I get now, but we weren't getting that earlier.

Thanks, dude! While 3G isn't perfect, it's much better now. I really appreciate it.
Not a problem just found it trolling around the forum.
In the newest Cyanogen 5.0.7-test2, the H symbol really means EDGE. Just download Firerat's voice and data fix and flash that. It will fix up the spotty 3G that you are receiving.
My 3G is working fine I just had to flash the kernel for Cyanogen 5.0.7 Test 1 to fix the battery drain
I don't think that is true because that is what pops up when you switch it to wcdma. If you switch it to edge it shows E so I am sure it is 3g, also a quick speed test tests at 3g speeds.
3G = 364 KBPS connection
HSDPA (also called 3.5G) = 1.5 = 3 MBPS connection

So, should we use 3G or HSDPA? I still get random network errors on 3G, but the connection is so much better than before applying the firerat update, fixing permissions, and using the method shadowofzeus suggested. To be clear, the last is what helped.
from my understanding is that HSDPA is the next step up from 3G. this rom just opened up the phone to being able to support the higher speeds.

Huh. I put my phone on 2g only when I'm at work to save battery (the 3g in this area sucks). I usually have it on 3g everywhere else. When I use something that needs data (twitter, browser, market) it jumps up to H, then back down to 3g when it's done transferring data.
I have had my SGSII for about 6 weeks now. Running it on the Telstra Next G network.
The problem is I am having a shocking internet experience.
My experience is based after coming from the HD2 running Android.
I have had the network freeze a few times. This is identified by the traffic arrows stay stuck. Airplane mode and back resets.
Basically cloud based apps like Market, Maps etc takes ages (60s-5mins) to start up. Kill and re-launch is quick).
Lots of network errors in Google Market.
Lots of Server unreachable errors in Emails (Pointing to exchange 2007)
I have updated the APN details to use Telstra.internet.
Great reception at home and work.
Calls and SMS's are fine.
Ideas? Waiting to see the Cyanogen rom. Wondering if my experience is due to Kies or another program getting involved with internet.
Any ideas please. My HD2 ran with the same Sim and worked like a rocket. No such issues.
Have you tried turning fast dormancy off? I'm on the Optus network, but I found with fast dormancy on I was getting unreliable internet (market would timeout a lot, doing installs/updates would fail straight away, etc). When I turned it off, I got better speeds and the connections were reliable.
Turn fast dormancy off:
1. In dialer - *#9900#
2. Select Disable fast dormancy
no such issues for me, using a vodafone branded handset. The only thing is that it will occassionally use 3telstra instead of telstra, in which case i need to manually select the network. a bit of a pain but not 2 bad

****************** FIXED ******************
After contacting Samsung for an insane period of time (ended up on an international call to England i think... or now that i think about it could have just been some English guy in Aus lol) I have got an official explanation and confirmation that this issue is being looked into for KE8 (but it appears that KE8 has been launched in India already so it might be KE9).
*disclaimer*
I am no expert on mobile technology this in-depth however the (probably very) dumbed down version the Samsung guy told me was this;
*end disclaimer*
The problem stems from the fact that this phone has 3 forms of data connection, 3G, HSDPA, and HSPA+.
3G is what we have all had since 3/Telstra launch 10 years ago.
HSDPA is the 7.2mbps connections that we got after that.
HSPA+ is the full fledged 42mbps Next G stuff that only Telstra has.
The problem is, when you are just using the phone as "a phone" it idles on a 3G connection to save battery and when you initiate a data connection it flicks on to the higher connection protocols for better speed.
What is supposed to happen when you initiate the data connection is the phone checks for H+ connection, then for H and then finally 3G. For some reason if you arent with Telstra or are in an area without HSPA+ the phone gets hung up for too long attempting to initiate the H+ connection and refuses to drop back to H!
Also, even if it does give up on H+ it then has an issue with falling back to 3G. Resulting in the problem that if it cant get H+ or the tower is too flooded for a H connection you get absolutely nothing until you restart the data mode within the phone, renegotiates with the tower and BAM, you are back in business.
So... there are 5 fixes;
1. Wait for KE9 (or what ever firmware fixes the modem timings etc)
2. Get a Telstra sim and never leave an area that has H+
3. Turn off/on data mode whenever it happens
to which i told him they were stupid answers and completely unacceptable, but then he came out with this complete gem!
4. using service code *#301279# you can turn off HSPA+ completely forcing it to start the data connections on HSDPA
5. using *#301279# again you can just turn off HSPA+ and HSDPA meaning it instantly starts downloading the data on 3G without delay
Now yes, i thought... great... ive bought this $779 phone that has all the latest and greatest technology and I cant even use it! But, I did some testing!
First of all my normal sim is Vodafone so turning off HSPA+ is an obvious one for me, im never going to get it so why bother. So now that the phone only attempts to get a connection with HSDPA the need to turn off and on data connection was getting more and more rare but still having the problem (i have a feeling that is due to congestion?). So i bumped it down to 3G only and it works perfectly 100% of the time!
The point of these faster connection protocols is speed so i did testing.
Vodafone sim, 4 bars of signal in the middle of a shopping centre.
HPSA+ turned on = 4mbps down, 1mbps up
HSDPA turned on = 4mbps down, 1mbps up
3G only = 3.5mbps down, 1mbps up
did this over and over and over again and to be perfectly honest, im willing to lose 500kbps to make sure that data always works and if you are just doing general web browsing the time it takes to initiate the HSDPA connection wastes more time than the slightly slower speeds with 3G does.
Now obviously this only works fine in my situation, if you are with Telstra and going from HSPA+ down to 3G means going from 20mbps to 3... i would be pissed. But for the rest of the country you are talking about a loss of less than 1mbps so in real world situations with just small amounts of burst data its fine
TLDR; Try and go online and the 3G up arrow lights up but never actually downloads anything
Dial: *#301279# – Change HSPA revision – Release 5 HSPDA only
test, if still a problem
Dial: *#301279# – Change HSPA revision – Release R99 HSPA off
Your welcome, Peace out!

THIS IS A GREAT POST (even if it is a repost from whirlpool)!
So many people appear to be having this issue (including myself on O2 UK) where the data connection is stalling.
That code (*#301279#) is a gem.
Whilst I am certainly not happy that Samsung have released this phone with such a massive issue (telling you to wait until KE9 for a fix is really quite terrible!), I would rather have this fix in the meantime whilst waiting for the new firmware.
I have just disabled H/H+ by selecting 'Release 99 HSPA off' and my stalling issues have disappeared. Furthermore, my down speed is still 1.5 Mbps and upload speed is also 1.5 Mbps. I am more than happy with that speed. As the quoted post states, if you want more than this speed, this solution will not be good for you.
Thanks for posting this dusty_nw, this has been bugging me for weeks.

If you have it enabled it will fall from H to 3G in 7 seconds when connection is idle, otherwise in 30 seconds. 7 seconds are to short it will lose time and battery renegotiating to H to often. Ex: when you read your rss feed it will renegtiate higher speed for every article you read, very annoying.

this should be stickied, fixed my issues i had on optus the connection would continually change from H, and 3g and stall i just disabled all except 3g and now its perfect and very quick great post!
One thing i did on mine with Telstra is change the APN from Telstra.wap to Telstra.internet made the internet feel better. Also got much better upload and download speeds.

May be a sillt question but.
I used the stock dialer and put *#301279# in
Menu popped up.
Used my finger to press "[2] Change HSPA Revision"
Pressed "[2] Release 5"
Goes to menu with two options of which none seem to do anything when pushed.
Went back to strat of menu and selected "[1] Release R99"
Same options and none can be clicked.
So am I not doing this right? Have the changes been made with no signs or message? If they have changed how do I get them back?
I expected the option to change to visually say its "off" or something.
Although no message came up it appears my phone is staying in 3g so maybe it worked... Although I am in low reception visiting the country side so maybe they don't have H or H+ anyway....
If I selected the first option does this restrict data to 3G?
Select 2nd option for H?
or Select 3rd option for H+ or unrestricted?
Is this how its works?
Edit: I have now found it works like I thought. The screen after I click either of the options then shows what is active and is the confirmation in a way. I jumped on the forum a little too quick......
Hi. I've book marked this because I get this issue thanks.
However it is worth noting that difference between 6 and 5 is only hsupa which is upload. So you wouldn't expect change in download speeds changing that going back to 3g of course affects both directions.

Telstra.iph works best for me in Perth.
I use a SGS2 (bought in Europe through Expansys) on Telstra since 2 months now, without any issue. I used several firmwares and kernels since then (not to test, just to update: KE7, KG2, KG3), all behaved the same way.
I tried two different APN (telstra.iph and telstra.wap), both gave me the same kind of speeds (quite good, except some times in the middle of the day).
I never found the datas to create the telstra.internet APN (they do not seem to be on ausdroid). Could someone point me to them?
As an aside, I've just finished testing the I9000TDUKF4 modem (yes it works!), if Telstra did actually have tweaks made as they claim, there was no discernible difference on Telstra's NextG using their 'T' version KF4 modem and a stock KG3.
Any changes if any must be on the hardware level or via software set tweaks, the modem really didn't make any difference at all to my download speeds.
For those wanting to replicate the experiment or muck around I've uploaded the Telstra 'T' variant KF4 modem here: http://www.multiupload.com/VKPFYPURD5

Any changes if any must be on the hardware level or via software set tweaks, the modem really didn't make any difference at all to my download speeds.
For those wanting to replicate the experiment or muck around I've uploaded the Telstra 'T' variant KF4 modem here: http://www.multiupload.com/VKPFYPURD5

Thanks for this, I just stumbled upon this thread, messed about with a few settings and getting much better use out of NEXT G

I've been following the mobile data connectivity issue that some users are experiencing (where data connection drops randomly, apparently coinciding with a lot of switching between 3G/H/H+).
Initially, people suggested disabling 'fast dormancy' using *#*#9900#*#*, however, this did not work for many, including myself.
In this post http://forum.xda-developers.com/showpost.php?p=15250511&postcount=6, there appears to be a solution, albeit a workaround.
I have started this thread, as there are so many separate threads about this issue, and only the Telstra Australia thread had this answer (as far as I've read). I have copied the post (a repost from whirlpool) by dusty_nz below. Basically, the problem is serious, the guys from Samsung have insisted this will be fixed in KE9, but there is a workaround in the mean time (disabling H+ and H, or just disabling H+ using *#301279#). This may seem drastic to speed freaks, but 3G connection alone should still give you 1.5 Mb up/down if you can put up with that. This has worked for me, no more data stalling, no more server errors etc. etc. I hope H/H+ will be fixed in future firmware.
Here is the post:

****************** FIXED ******************
After contacting Samsung for an insane period of time (ended up on an international call to England i think... or now that i think about it could have just been some English guy in Aus lol) I have got an official explanation and confirmation that this issue is being looked into for KE8 (but it appears that KE8 has been launched in India already so it might be KE9).
*disclaimer*
I am no expert on mobile technology this in-depth however the (probably very) dumbed down version the Samsung guy told me was this;
*end disclaimer*
The problem stems from the fact that this phone has 3 forms of data connection, 3G, HSDPA, and HSPA+.
3G is what we have all had since 3/Telstra launch 10 years ago.
HSDPA is the 7.2mbps connections that we got after that.
HSPA+ is the full fledged 42mbps Next G stuff that only Telstra has.
The problem is, when you are just using the phone as "a phone" it idles on a 3G connection to save battery and when you initiate a data connection it flicks on to the higher connection protocols for better speed.
What is supposed to happen when you initiate the data connection is the phone checks for H+ connection, then for H and then finally 3G. For some reason if you arent with Telstra or are in an area without HSPA+ the phone gets hung up for too long attempting to initiate the H+ connection and refuses to drop back to H!
Also, even if it does give up on H+ it then has an issue with falling back to 3G. Resulting in the problem that if it cant get H+ or the tower is too flooded for a H connection you get absolutely nothing until you restart the data mode within the phone, renegotiates with the tower and BAM, you are back in business.
So... there are 5 fixes;
1. Wait for KE9 (or what ever firmware fixes the modem timings etc)
2. Get a Telstra sim and never leave an area that has H+
3. Turn off/on data mode whenever it happens
to which i told him they were stupid answers and completely unacceptable, but then he came out with this complete gem!
4. using service code *#301279# you can turn off HSPA+ completely forcing it to start the data connections on HSDPA
5. using *#301279# again you can just turn off HSPA+ and HSDPA meaning it instantly starts downloading the data on 3G without delay
Now yes, i thought... great... ive bought this $779 phone that has all the latest and greatest technology and I cant even use it! But, I did some testing!
First of all my normal sim is Vodafone so turning off HSPA+ is an obvious one for me, im never going to get it so why bother. So now that the phone only attempts to get a connection with HSDPA the need to turn off and on data connection was getting more and more rare but still having the problem (i have a feeling that is due to congestion?). So i bumped it down to 3G only and it works perfectly 100% of the time!
The point of these faster connection protocols is speed so i did testing.
Vodafone sim, 4 bars of signal in the middle of a shopping centre.
HPSA+ turned on = 4mbps down, 1mbps up
HSDPA turned on = 4mbps down, 1mbps up
3G only = 3.5mbps down, 1mbps up
did this over and over and over again and to be perfectly honest, im willing to lose 500kbps to make sure that data always works and if you are just doing general web browsing the time it takes to initiate the HSDPA connection wastes more time than the slightly slower speeds with 3G does.
Now obviously this only works fine in my situation, if you are with Telstra and going from HSPA+ down to 3G means going from 20mbps to 3... i would be pissed. But for the rest of the country you are talking about a loss of less than 1mbps so in real world situations with just small amounts of burst data its fine
TLDR; Try and go online and the 3G up arrow lights up but never actually downloads anything
Dial: *#301279# – Change HSPA revision – Release 5 HSPDA only
test, if still a problem
Dial: *#301279# – Change HSPA revision – Release R99 HSPA off
Your welcome, Peace out!

this works! thanks!
Cheers!
Just tried this and I got 1800kbps on 3g!!
Hmm, i played around with those codes. If i choose to drop H+ and H, stays on 3G, but speed is crappy for me. So i want to drop only H+, but when i do that phone stays only on 3G too, not attempting to connect to H. Am i doing something wrong ?

*#301279#
Option [1] Release R99(HSPA OFF) - This should turn H+ and H off
Option [2] Release 5(HSDPA ONLY) - This should turn just H+ off (what you want)
Option [3] Release 6(HSDPA/HSUPA) - This should turn H+ and H on
To test this, you might want to make sure you are in an area that can pick up 3G, H and H+.
One week on since I selected Option [1] and I have not had any data stalling issues, before I was having data dropping every few minutes whilst browsing.
I tried Option [2] and still had the stalling issue.
Good luck.

I hardly ever get H+, which is why i want to turn it off, thing is if i choose option 2, i only get 3G, while with option 3 i get 3G and H (probably H+ too if i were in the right place). Option 1 works fine, doesn't seem to stall, but 3G speed is crap in my network, that's why i wanted option 2.
Tried all three settings and I am getting about the same speeds with all three settings, 3600-4200 down and 1550-1620 up. So will try setting 1 to see if my connection carries on dropping out.
Thanks
Wat is the code for miui

I actually tried this before on a few different radios and it didn't really work. The real problem I have is when I get in an elevator for a minute and get out shortly. It's not long enough in the elevator for the phone to say "No Signal" but it's still long enough for the data connection to hang and never bother hooking back up when I get off the elevator.
I'll try again though... will report back.
same here .... i tried the three options but problem persist
I have tried the codes above, including disabling dormancy but my internet still will not connect to the internet. Please help.
I'm with Optus (TPG) and I never really see H. It's either 3G, or H+.
I tried disabling H+ (option 2), and like the other guy now I only see 3G.
My Speedtest with only 3G was:
Down - 228.2kB/s
With H+ enabled (option 3), my Speedtest was:
Down - 482kB/s (but it's been as high as 1103.9kB/s in previous tests.
For now I'll just keep it as it is and put up with the occasional freezes. Hopefully it's fixed soon in a firmware release.
i cant seem to get the codes working.. after i dial *#301279# nothing happens, no menu nothing. tried on my wife's galaxy s 2 same thing.. is there an app to disable HSDPA?
\\Issue solved
Is this issue mainly due to the carrier?
I did not have this problem b4. Now I found that my phone might suffer from this.
Tried to disable the H+ or H & H+ at the same time, it seems the issue is still there.
I am on Vodafone Australia network. And I just raised this similar topic on Whirlpool, if you guys would like to discuss this network problem on an OZ forum, plz refer to the below

For me it's still the same, coming from KF2 to KG2. Will try KG3.
Any one with new modem firmware that 100% fixed the 3G drop/stuck connection(only see upload sign lit) bug? I am running KG1 modem(stock rom no root) and still experiencing this issue on ATT in Bloomington, Indiana USA.
I also realized S2 uses Infineon modem chip which is the same supplier for the iPhone3G that had the 3G slow down, drop call issue..
Could this issue be the chip at the end?? Why would Samsung taking forever to fix this critical flaw on I9100??
I'm on 3 UK. Had the cutout on KG1 and KG2. But it's definitely gone away in KG3.
I'm on Airtel India on KG3 and I still have the data stalling issue.
Seems to me like this issue surfaces more when I'm at home on wifi and then step out to data.
Trying out these service codes now to see if it helps to turn off high speed data.
It would make sense for Samsung to include these settings in the rom itself even for those without issues but want to save battery.
