2G vs 3G battery - XPERIA X8 Q&A, Help & Troubleshooting

Battery Standard battery, Li-Po 1200 mAh
Stand-by Up to 446 h (2G) / Up to 476 h (3G)
Talk time Up to 4 h 45 min (2G) / Up to 5 h 40 min (3G)
Music play Up to 23 h 40 min
When i select "only 2g networs" from my settings, it says "saves battery"
what the hell? misstype by gsmarena?
or 3g battery > 2g battery only for x8

Not very well what is the question, but the reality is:
Doing the same.
With 2G came at 11 pm on a 60%
With 3G arrived at 11 pm on a 20%
Now you decide.

So strange, you should do more research on Google about this strange results! ! !

Edge (E) network log in

Hi guys I got a question
I noticed recently for the first time that my Xperia has started using "Edge" networks ie. whenever I m in an area of relatively weak reception (that is pretty much the whole of London with this handset) the phone goes from "G" to "E" - which it never used to do befor (I ve had my xperia for a year now).
Just to clarify what I m taling about. You know how your reception strength is shown to u in bars and a letter eg. H - 4 bars, 3G - 4 Bars, G - 4 bars .. mine shows me now in areas of weak reception whenever I try to use the internet E - 2 / 3 bars.
What does it mean and how did this happen? The only reason why I m a bit worried is because the only time I ve seen this E come up before was when I was abroad. So I m worried about extra charges.
I m with Vodafone UK on Contract.
Thank you
The letter indicates type of network you are connected to:
H = HSDPA (Highest speed 3G or 3.5G)
3G (or U) = UMTS ("Standard" 3G)
E = EDGE (Higher speed GPRS or 2.5G)
G= GPRS ("Standard" 2G)
If you are experiencing a drop from H or 3G to E don't worry about it, it just means that it cannot connect to any 3G towers. I have it occur on occasion, usually when I am in more remote areas. It also occurs when the local towers are having issues or they are upgrading service.
Don't worry about additional fees, unless you are roaming. Just check that you are still using your home network. If so, no sweat.
Also, going from G to E is an improvement. G is the worst type of data transmission.

Would you rather have 4-bars on 2G or 1-bar on 3G?

Most of my day I am in a location near a 2G tower, but within range of a 3G tower. My phone seems to bounce around between 0-2 bars on 3G (when it is 0 bars on 3G I mean that it switches to 4 bars on 2G).
If I turn on "only use 2G networks" then I am consistently 4 bars. I'm tempted to just lock-in the 4-bars, but I don't know much about cell technology.
Well your battery will last longer not switching between the two all of the time.
Even a 1 Bar on 3G will be many times faster than 4 bars on 2G. So it depends if you want temporary speed or not.

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] Stay on H+ rather than H connection

I have already disabled fast dormancy using *#9900# code in my Note, but now my phone switch between H and H+ icon. When connection is idel, it falls back to H. If I browse a webpage, it takes more than 10 seconds to connect to H+. And yes, H has no data trafic avalable. That means I have to wait the phone to change to H+ if I want to browse the internet.
Does anyone know how to stay with H+ icon?
OMG no one knows?
I think it depends on your rom..

It depends on your Network and rom + modem u using.
Post the details here and lets see what the community here can find.
Data works fine on H. It certainly seems faster on H+, but, as you say, the phone spends so long finding and connecting, the speed is wasted. I'd be happy to stay on H myself.
I agree, it would be nice to keep to one. My connection jumps from 3g to H to H+ and even to E, especially when moving on a train.
I think it is network dependent
E - Edge 2G
H - 3G
H+ - 3.5G
When you set your network mode to auto, it searches for faster avaiable network. If you set it to only WCDMA, you won't get E, but i think there is no setting to select 3G/3.5G.
Another problem to select WCDMA is, whenever any place dont have 3G coverage, your network will lost.
In germany it is also other:
G - gprs up to 56kpbs
E - edge up to 128kbps
3G - umts up 384 kbps
H - HSPA up to 14 mbps
H+ - extended hspa up to 21mbps
But H+ is only active when it is needed and it is all carrierer depending. If i am on H+ i can se my battery dying

It is network related there's nothing your phone can do about it.
H+ is actually using the 64QAM modulation over the air interface which gives you 50% more throughput ideally than H.
3G is up to 384kbps
H is up to 14.4Mbps (16QAM)
H+ is up to 21Mbps
The above is the throughput on the lower levels, so at the application level you will get around 10% less (and that's if you are alone using the base station and your carrier is not limiting your throughput)
Everything that goes through wireless interfaces has to be shared between users. Therefore, the network has to manage valuable and limited resources to serve everyone and provide a best effort service. In order to do that, idle users or users below a certain threshold will be down switched from H+ to H (this usually happens due to radio signal conditions) and to 3G. After that it kicks you back to idle mode, so even if it says H, your actually not connected until a new session is triggered and based on your needs and availability, you are up switched to a faster channel.
Depending on each country and their marketing:
2G
2.5G is GPRS (G)
2.75G is EDGE (E)
3G
3.5G is HSPA (H)
3.9G (4G in the US) is HSPA+
4G is LTE
Fast dormancy is a new feature on 3G networks (not available in most networks yet) that improves your switching between different channels (H+, H, 3G, idle, ....) and it has a major impact on your battery life and the speed of establishing a new data connection once you are idle. This is also controlled by your network. Anyway, some people believe that turning it off while it is not supported by your network can help improving battery life. Which I don't think is true, since by turning it off you are forcing your mobile to ignore this new feature (and if it doesn't exist there's nothing to ignore anyway) and turning it off shouldn't have any effect unless it is active on the network and your carrier is not managing it correctly.

There is a short code for turning off h+ my phone would always time out when trying to connect to h+ so disabled it. And it works great now, can't for the life of me remember what the short code is though!

Is there a code to turn on H+ too? Because my phone used to show H+ but now it only shows H although I have not changed any settings.

[Q] 2g only network selection for Galaxy note??

My previous Android had the option of switching to 2g only network to save battery life. But this is not available on Galaxy note.
I have noticed that stand by battery usage spikes considerably on 3g network.
I don't need 3g speeds on stand by but i want to stay connected to receive regular updates.
Regrading battery usage in standby :
on 2g only i use to lose about 5% battery overnight ( about 8-10 hours) = less than 1% per hour ( I am more than happy with that rate)
on 3g my battery drain rate is 8% per hour???
Any idea guys?

I know that would work but switching over to GSM only and selecting networks seems to take to much time for my liking
Can't we somehow have the old system where I can just check or uncheck "2g only network"?

You could look in the Play Store for an APN widget this woud disable the data connection when you don't want to use it.
