I used my phone as a wireless modem and the battery drains fast while wifi is on. I have my phone connected to the charger but it still drains the battery to the point that i will loose all charge. Is there a way to keep an active charge and use wifi at the same time

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
My Desire HD behaves very strangely when I am at my office, draining the battery (with screen off) at an average rate of 60-70mA, while at home the drain is what most people get with custom ROMs (3-4mA).
The difference between office and home? I have examined what differed between the two and I have found that it has to do with the wireless network.
At home: wifi router
At the office: Windows 7 computer with USB Connectify "router"
I know it has to do with wifi because if I turn wifi off at the office, the drain is also 3-4.
I also know it is not just apps or data synchronization because at home I have everything the same way and the drain is 4-5mA.
Further, if I turn connectify off (and lose my wifi router) while leaving the phone's wifi on, I get the same low drain that I get at home.
I am sure it has something to do with Connectify, but I have no idea what is the difference (from the phone's point of view) between connectify's wifi and my home router wifi.

Hello there.
I have a question about 3g handle. In WindowsMobile 3G connection was NOT battery eating. There was small diffirence between 3g still on and still off.
In Android there is big battery drain even if 3G is connected but not used (even synchronization is off). With 3G connected I can handle phone for....max 6 hours.
Is there any possibility to turn 3G only for stay connected (ping?) and get less battery drain?

Totally un-scientific test but what I've found is that WiFi is the biggest drain on the phone and in particular WiFi N usage.
Tests over 3 nights (left over night same apps running each night)
1st night Connected via WiFi N connection - lost 40% battery in 7 hours
2nd night Connected via WiFi G connection - lost 15% battery in 7 hours
3rd night Connected via 3G/HSPDA - lost 8% battery in 7 hours
Charging the battery also takes twice as long when connected to WiFi N
Don't know if this is a bug or the power requirements of WiFi N (maybe that's why Apple don't/won't support it?)
What firmware version did you use?

I can confirm charging takes much longer if connected to wi-fi n, i usually set wi-fi policy to off when screen off, this way charging takes the usual time. How do i set my wi-fi to g connection instead of n ? I'd like to test too, battery seems to drain kinda fast when connected to wi-fi n.

I think it depends on what router you are connected to. It has been said that D-link routers causes a higher drain than others.
So which router do you own?

OT but how do you do that?

Menu item names might differ, translating from swedish.
Awesome thanks for the tips

The opposite is true for me. I have my wifi sleep policy set to "never" and I lose 1-1.5% an hour overnight. On the other hand, the signal at my house drops in and out so if I spend the night on 3G/HSDPA there is a large drain.

OMG, I completely forgot about those settings. I remember seeing them once when I first got my device but never looked again.

Hi everyone,
I recently updated my N7 2013 to 5.0.1 and found that the battery was draining faster when compared to Kitkat 4.4.4. It's one of the few devices on my network that run on 5Ghz so I switched the radio over to 2.4Ghz and found that the battery drain was much less.
Here's how I tested it:
1. Connect to 5Ghz wireless AP and let it stay in sleep/idle mode overnight.
2. Observe battery graph.
3. COnnect to 2.4 Ghz wireless AP and let it stay in sleep/idle mode while at work.
4. Observe battery graph.
After looking at the battery graph I see that the dropoff in 5Ghz is steeper than when operating in 2.4Ghz.
Any ideas?
Radio waves have to move twice the speed, thus twice the battery drain.
