WHAT IS UR MAX HRS of USAGE OF WIFI

HELLO CO-XDA_DEV, pls post ur most usage hrs when using wifi on wizard and state what ROM ur using. i will test mine now,will post later.
PLS post to verify what is the best ROM/COOK ROM here in XDA_DEV is the best for wifi usage, TNX people!

Probably should post your power settings too.

finally got mine:
ROM: SHOGUNMARK ROM(congular 2.26 mods)
ROUTER: LINKSYS WRT54G
wifi setting in default:
range within the router: 20ft
battery status: 100%
hrs of testing: 1 hrs
battery comsumed: 18%
remained battery: 82%
problem: connected with the LINKSYS WIFI ROUTER but SOMETIMES no DATA transaction, dnt know why, so i have to disconnect and connect again(did it twice for a 1hr testing)
wifi setting in MAX performance:
range within the router: 20ft
battery status: 100%
hrs of testing: 1hr
battery consumed: 33%
remained battery: 67%
problem: NONE
both test used TCPMP player and played a movie all around.
I notice that when i put my wifi setting to MAX i can easily connect and transfer data tru WLAN,but when in default setting i have WIRELESS CONNECTION,I mean i have connected to the router but no DATA TRANSACTION . maybe because wizard has issue with LINKSYS or it's just my wizard.
hope somebody post their review with testing the wifi usage, so that i may knw if it has issue with linksys or other wifi router brand or maybe the ROM, gonna again with another ROM

Using Wifi via WMWifiRouter consumes battery even when on AC power

Hi,
I use WMWifiRouter to share the 3G internet on my Hermes on my laptop. The problem I'm facing is, even with the battery fully charged and having the mobile on AC power - the battery runs out by 3 hours at max.
Is this normal behavior? Is the power consumption really that high when using internet (GPRS/HSDPA) and Wifi at the same time?
(my apologies in advance if this has already been answered - i tried the search )

I don't know exact figures, but usually running 3g/HSPDA will drain the battery pretty fast, using WiFi will do the same, both together and I think it could be reasonable to see the phone die after a few hours of constant usage. But, if its plugged into AC power, I don't see why it would drain at all, or at least that fast...I am sure someone with more knowledge than me will chime in as well...

i used to be regular wmwifirouter user with my hermes and i can confirm that battery will jux drain regardless u put it in charge with usb or ac.
if i recall correctly, i think i see it somehere tat hermes has known issue that the charging will stop if it's get overheat and YES when using WIFI & 3G it can fried egg.
anyway, i hv quit wmwifirouter and stick to internet sharing with bt / usb

thanks for your responses... i guess than this is not unexpected.
and yes, it does heat up like anything. Also, sometimes it would stop charging as soon as i launch WMWifiRouter (infact i've noticed this behavior without WMWifi Router too :S) but usually quitting and restarting WMWifirouter or restarting the device fixes it.
The reason I can't use it with BT is that the signals in my room are really low, so i usually leave it in one end of the room where the signals are relatively strong and connect via Wifi
tried an HSDPA router I got from work, that fixes my issues, but I am still evaluating whether its worth it to purchase a router of my own

3g and h

I saw that when I switch my apn on. What does h stand for?

HSPDA I think
Bascially when my phone download it displays a H and when it's not it displays 3G

Yes, it's HSDPA. It's faster than 3G, so it's good if you see that, it means that your provider has faster internet
On Nokia handsets, HSDPA shown as 3.5G .

uhm does that mean i have am using a premium service that requires me to pay additional lol?
it wasn't like this. It recently became H from 3g only. :X

I've never heard of HSDPA being charged as a premium service. It's just your providers network.
Anyway you can disable it from them settings if you want. Just go to Settings>Wireless and network>Mobile networks>Network mode and choose GSM only. An alternative is to use APNdroid from the market.
I disable it when I'm in a WiFi network or when I don't need a data connection because it uses more battery.
I use the "WCDMA only" (forces HSDPA on) when I want a data connection so my phone does not switch to GSM automaticaly. Be careful if you use that option though. If you move to an area with no HSDPA coverage, your phone won't switch to GSM and you'll have no network connection

I thought if you were on wifi, the phone automatically turns off the mobile data connection?

That's partly right. It does not send or receive data through the mobile data connection but that does not mean it switches to GSM network. It stays connected to the HSDPA mobile network just handles the data requests through WiFi. In my experience anyway

True, but if you don't go into WiFi/Advanced/WiFi Sleep Policy and set it to NEVER, when your phone goes to sleep so does WiFi, which causes the 3G radio to turn back on and using wireless data for updates, email checks, etc.
Long story short, if you're spending a lot of time in a WiFi area, set it to never sleep to save a lot of battery and a bit of data usage.
If you're moving around a lot, leaving WiFi on when the phone is sleeping will use more power, because not only is your 3g radio on, so is the WiFis, as it's constantly looking for a known network to hook up to and scanning for new ones.

Hi I have a few questions about your comment here. I am in an office connected to wifi all day at work and when at home connected to wifi. When I look at battery usage it states
Display 46%
cell standby 19%
phone idle 12%
mario live wallpaper 9% (highest ive seen it but it is the best thing on this phone)
...
...
Wi-Fi 2% (lowest item in list)
Are you saying if i tell it to never make wifi sleep then cell standby usage will go down and i will use less network data? and battery usage will be less then if it makes wifi sleep?
Also if i do this when I am not in office/home and i disable wifi will that also save me some battery?
At the moment i just have wifi on all the time and let the phone use what it wants to.

I believe "cell standby" does not talk of ACTIVE 3.x/2.x G connections! So you should not be looking at that parameter. However it is interesting for us to know that WiFi hardly use any power. "cell standby" should only talk of when mobile is really in standby or display off, low power (suspended) mode.

3G radio uses a LOT more power than short range WiFi. When WiFi is on and connected, the 3G connection is totally turned off. Totally.
Think about it this way...once you get past the new and shiny phase of owning your device, it probably spends MOST of its time with display off and sleeping. So, it will spend a LOT of its time connected to 3g if you let the WiFi go to sleep.
Turning Background Data and Autosync off will prevent the 3G radio from switching back on when WiFi is sleeping (and prevent WiFi from using much transmitter power when awake as well). But turning off sync/background data is not ideal if you need emails or whatever as soon as they are sent, accurate weather forecasts, etc.
Least battery usage is of course in Airplane mode with WiFi and Bluetooth turned off as well, since there is no radio activity at all. But we bought these devices in part because they're connected and "always on" data is coming in.

Here is how I do it:
I use APNdroid to switch 3G off when it's not needed. I find that I only rarely need 3G. Seems that you do not need it either.
I leave WiFi sleep on because tbh I have no reason not to. When WiFi goes to sleep 3G does not autoconnect anyway because of APNdroid.
That way the phone uses plain 2G when no data are needed. When data are needed it uses WiFi most of the time and 3G only when no WiFi is available and I manualy select to put 3g on

Sorry to chair another question.. I see a 'g' logo sometimes... Instead of 3g and h. What's g?

G = GPRS ( General Packet Radio Service )
E = EDGE ( Enhanced Data rates for GSM Evolution )
3G = 3rd Generation ( I unno, wtf. )
H = HSDPA ( High-Speed Downlink Packet Access )
Basically G(PRS) operates over GSM, it's from dial-up speeds to twice as fast as dial-up.
EDGE operates over 2G, it's almost as fast as standard DSL, about 400kbits and a maximum theoretical 1Mbit.
3G operates in tandem with HSDPA, infact technically HSPA is the technology that is used on the 3G network. It is typically up to 7.2Mbps, with a maximum theoretical of 14Mbit.
HSDPA and HSUPA are specific aspects of a HSPA enabled system. They are Down link and Up link capability respectively.
When you see H, the phone is going from a stable 3G connection to a boosted power consuming ( which is why it isn't constantly on ) state in which it can download very quickly.

[Q] Wifi on - power consumption too high

I've noticed that the Note uses way too much power when I'm using the phone with Wifi-on vs when using it with 3G on, like 2 times more power.
I wonder if it's the wifi chip used in the Note or my wifi router at home (Tp-link 1043ND 300mbs N class router, 11b/g/n auto channel, auto 20/40mhz)
Same with stock rom, cassie's and rocket rom.
B/c of this I've started using the 3G access even at home, but I'd prefer to use wifi.
Anyone can fill in on this matter?

have same router, but I doubt it's cause of it.
With my dell streak I would lose around 3% battery overnight with wifi on, with the gnote I lose around 10%.
Really sucks.
I got this program, wifi TX power, but still din make test to see if can it works on the gnote to reduce wifi antenna battery usage.

some router seem to have problem in battery drain for wifi. 2wire have this problem too . best way is disable wifi when you are not using?

I've noticed something, don't know if it helps though. After connecting to a wifi router, go into settings --> wireless and networking --> wifi settings (the tab where you view the available wifi networks).
On stock 2.3.6 KK5 even if i am connected to a router it keeps scanning continuously for other wifi hotspots (look for the little circle on the right). I found no option to disable auto scanning. I have notify for open networks disabled. I don't see the same effect on my X10.
Any ideas if that causes the drain?
Edit: I've emailed samsung about the above mentioned in this post. Hopefully they will clear this up.

WiFi 2.4GHz vs 5GHz Power Consumption

I have been researching on Power Consumption between 2.4GHz and 5GHz WiFi. the reason for that is my Exynos N910C seems to drain so much battery when it's on 5GHz WiFi during stand-by / sleep. And of course drains even more when in use.
My set up:
1. Asus RT-AC87U, WPA2, 2.4Ghz and 5GHz, SSID names are differentiated between the 2 bands, eg. WiFi and WiFi 5G.
2. Router placed on the Ground Floor around the back of the house. My Room is upstairs around the front of the house.
3. WiFi Signal strength: 2-3 bars for 2.4Ghz, 1-2 bars for 5Ghz.
4. Phone is not rooted, everything stock, latest firmware, bloatware disabled, only GMail Auto Sync, and WhatsApp running.
5. Phone has been Factory Reset and even reflashed with the latest firmware.
6. Under WiFi's Settings, I unchecked Smart Switch and under Advanced settings, I pretty much unchecked everything in there.
7. Under *#0011#, WiFi is set to Power Save ON.
This setup drains around 1-1.5hr per battery % on 2.4GHz (logged with Battery Monitor Widget) but 20-30 minutes per battery % when on 5Ghz.
At first I though, it could be because the signal is weak in my room, so I bought RP-AC52 and configured it as an Access Point (not as a Repeater) in my room. Once set up was completed, both WiFi band signal are now at full bar so I went to test it again..... but the battery drain rate remains the same! The phone is just 1.5 meters away from the Rp-AC52 Access point.
I've looked up on articles regarding the power consumption between the 2, they keep saying they should be the same, but it is clearly not at least on my phone.
Could anyone test 5GHz WiFi power consumption please and see if it's just me? Thank you in advance.

Higher frequency always means higher consumption.

I kinda figured that part, but 3x the power consumption vs 2.4GHz? And I'm sure alot of people here with dual band routers prefer 5GHz, but I wonder if they are aware it's such a battery hog compared to 2.4Ghz... or even 4G.

A late answer here but if someone is searching in the thread.
On the 5 GHz band of the AC87U, I cannot seem to get the powersave mode of wifi to work, which would explain why the draining is so high.

My experience of using 5ghz on my Snapdragon, is that it would always disconnect when the phone was asleep, even if I had always on. When I unlocked the screen it would take some seconds, then it would connect again to the WiFi. So I'm only using 2.4ghz now.

I have never had any problems with 5Ghz on the Note 4 Snapdragon. The last time I checked I think it drained around 1%/hour, maybe less. The fact I'm using FreedomPop on it though does really hurt the battery for obvious reasons (constant VoIP connection).
I wish Google Apps were less aggressive though. I have my old Optimus 3D as a backup phone with an extended battery and gets 14 days WiFi off, 7 days WiFi on with Google apps signed out, only a couple of days with it signed in.

Same. I guess you know by now why that happens. Reasons are DHCP timer, AP balancing, server side software bug, interference, ARP flooding and Wifi Multicast.
I have spent past few weeks scouring through the internet and finally learned about them all one by one.
