Has anyone experienced high battery usage on 2.4ghz WiFi networks? I am seeing my battery drain alarmingly fast at work (2.4ghz) at university and on the train (also 2.4ghz) but at home (5ghz) I have no issues and get well over a day of battery with 5 hours on screen - at work if I turn WiFi off my battery completely levels out and gives good performance. If I leave it on I will get 10 hours off battery with 3 hours on screen and it'll die.
Anyone seeing anything similar? If your battery life is extremely poor try turning WiFi off or using a 5ghz band. Quite annoying. I am on UK Vodafone with the G920FXXU1AODG OTA. Although the battery drain on 2.4ghz networks occurred before this version.
I am going to turn my home router to 2.4ghz tonight and test it with that, could just be my work, uni and train have terrible wifi!!

what is better to use... when it comes to battery consumption...
wifi or 3g?
and is there a big difference in speed?
sorry for the newb-like question...
Wi-fi is better for battery life, and its usually faster than 3G

I found, according to Juiceplotter, that my phone dies a tad bit quicker when I'm connected to wifi at home as opposed to 3g. Funky but true. Slopes of wifi usage decrease a lot quicker than the slopes for 3g usage.

I was losing 30% every night with my phone sitting with the screen off and wifi set to never sleep. Last night I disabled the wifi and lost 3% over 8 hours even though I was only getting 1 bar or signal and have autosync on for weather, facebook, email. I am going to try to leave wifi on tonight with it set to only stay on when plugged in and see how much it will drop.

I agree setting wifi to never sleep will kill your battery quicker than 3G overnight. I use Wifi when I am at work because it is faster, I am not 100% sold on the idea that it uses less battery than normal data. Especially if you do not normally use a lot of data.
I got my HTC Sensation a couple of days ago. With a full charge and with GPS, Wifi, Bluetooth and 3G disabled, the phone dies after 10 hours moderate use.
The coverage by my operator in the area where I live there is a constant signal fluctuation.
I have heard that this can cause battery drain. Is this true?
This is very true. When I go to areas with little or no signal, my battery dies twice as fast.
dial *#*#4636#*#* and set it to GSM auto (PRL). Should considerably improve your battery if signal is weak, but won't do anything for your reception.
This is something I've noticed drastically with HTC Android phones, my Desire was exactly the same.
On my Sensation I usually get reasonable battery life, a little better than my Desire. With moderate use when the signals decent (3 -4 bars average) easily 20- 30 hours with 4 - 5 hours screen on time. However if I spend the day in a location with very poor reception (0-2 bars average) I just about get a full waking day of 17 hours with 3 hours screen on time. Thankfully I usually have a decent signal.
After a few complete charge and discharge cycles you should see an improvement on that poor 10 hours you got though. I recommend you completely discharge the battery untill the phone shuts itself down and then charge the phone over night while its switched off for the first 4 charges to calibrate the battery well.
Cheers
I charged my phone to 100%, turned of mobile data.
I turned on wifi,GPS and connected the phone to my wifi-router (100% signal from the router).
The Sensation has been running with no charger connected since 22:00 CET yesterday and time here is 08:52 CET. The phone has only lost 29% of power since last night.
Compared to yesterday when I took it to town on a full charge with GPS, Wifi and GSM Mobil-data turned on. It lost almost 35% of power in three hours.
I know I properly can't compare Wifi and GSM data, but if it was the case one could conclude that what could be killing the battery life of the Sensation is bad GSM/3G data coverage?
Poor reception has always been main battery killer on sby. Change setting I mentioned, should improve.

Okay I will try..
What is the maximum life anyone has gotten out of a sensation?

Having problems with battery life also. What exactly does doing what u mentioned do?
Instead of constantly searching for 3g it sticks with gprs, until sufficient 3g signal is found.

It has been alive for almost 14 hours now with GPS, Wifi and turned on and connected to my AP and Cellular data turned off, but with a regular GSM connection to the Operator network so I can send and recieve texts and recieve and dial out calls.
By the way when your Sensation jumps onto a 3G connection do you feel it getting warmer?
Also flash the latest radio.
I recently bought a g2x. I previously had a Optimus v with cm7 that I liked, so I pretty much immediately installed cm7 on my g2x. I've noticed my battery will drain 25% on stand by overnight. Just wondering if this is normal, and if the stock rom is any better in this regard?
Well...its normal but at the same time its not, and i'll tell you why. Mine drains about 5-10% overnight (around 7 hours) and with wifi on it is usually even less, about 3-5%.
Though there HAVE been instances where it has drained about 20-30%, usually I just pull the battery (or restart the phone a couple of times) and it seems to fix it till the next time it happens.
In fact just last night it drained 35% =\ but normally it is around 10%.
Im on weapon G2x
My phone drains about 3% overnight. Wifi and data off. CM7 with Faux kernel and setcpu screen off profile.

It honestly depends what kind of network signal you're getting.
I've had mine drain a considerable amount one night just because I had low signal. Especially when you have low signal AND data on.
Mine drops 5-10% at night, sometimes less. I either keep it on 2G with data off or wifi with wifi calling on. Wifi calling seems to save a ton of battery.
But, leaving data on and 3G on I drop 30% or so.
yeah, as everyone says, depends on your usage (and/or signal). i've gotten 12h, i've also had 4 days, it really differs on lots of factors.
When I got my S2 10 days ago, I followed advice to help with battery life by switching off wifi and NFC. Battery life has been very good (currently have 62% after midnight having taken it off charge at 7am). I charge every night so I could turn wifi on but what would the benefit be? If I go upstairs in my house without taking my phone the BT connection drops. Would wifi prevent this? Is it an either/or BT/wifi connection or can they both be used at the same time?
The point of wifi is to keep your connection when you loose bt connection. I question how much battery you save if you phone is constantly searching for bt connection. I have wifi and bt on all the time and have about 48% at 11 pm
Hi, i have Note 10 Exynos Version, phone was fully charged (100%) at time i was gone to the bed around , i turn off all the futures like wifi, NFC, Etc... i shocked when woke up and found battery is on 74%, i had s7 edge and never face sych iss5its hardly uses 3% max un standby, sometimes My note 10 drain 18%, 20%, i had checked everything but couldn't found reason for battery drained in standby, not installed any fancy app, its not show any background uses of any app, i dont know how to attached screen shot to this thread otherwise it will clarify more about issue..... help me to resolve ..
Sync and Bixby routines are major candidates for overnight/standby battery drain.
Even i face the same overnight drain issue which never happened with my S10+, but not as much as 24%.
It has also got to do with your network signal strength in the place were you live.
Hi , the point you mentioned about network signal strength seems possible culprits, i barely get 1 to 2 bar signal strenth (idea network) at home, secondly sync and Bixby routine was already turned off, is it possible that poor signal strenth should tole that much on battery? I had s7 edge and its it's never drained that much battery even at poor network signal strength

Look under your battery settings, should show more detail about what is consuming what amount of power and go from there.
Hi, if i turn-on the flight mode at night before bed, phone won't drain battery at standby, its draining graph stayed flat at night, so i assumed that main culprit is poor network signal.... by the way can u enlighten me how to add/attached screen shot herewith if i wish to? As i dont found any option menu for that....

To attach an image, scroll down a little and there's a button to attach it or you can upload it to imgur.com and share the link here.
As for your battery drain, the main culprit is always bad battery signal. So maybe try locking it to 3g and try it out.
Sometimes when the network is bad and the phone wants to sync, it will fail and keep trying. It's an issue which plagues samsung to be honest. Had it once as well on my note10.
