I do a lot of browsing on my milestone, i predominately use 3g/HSDPA but wondered if using wifi is better on the battery life? Any views or knowledge on this?
It depends what kind of internate usage. For example browsing or some other active internate usage meant 95% of battery drain will be the screen+CPU, so it doesnt matter what you use.
But if we talk abaut constant internet connection in the backgroud i can tell you 3G/HSDPA uses a A LOT more battery than WIFI or 2G. I went from 2G to WIFI and no real difference. But 3G has some isues with constant connection, i think the reason is, there is no real low power mode for 3G. So either have WIFI, or only turn on 3G when you need and put back 2G, when you dont use your phone.

WiFi on this device is amazing. I use it at home and work and noticed a large boost in battery life, almost doubled my battery life.

yep same here
cheers guys will be testing wifi out over the next week and see if it helps the battery life!
Hmm, I was wondering. What is your battery life on constant 3G (web browsing, google talk etc.) usage and on stand-by mode?
The milestone's wifi is one of the less consuming wifi chip ever seen on a phone.
The 3g, instead is exactly the opposite, specially if you are on fast network (10 or more Mbps), specially if you are using an old FW.
My milestone was lasting in about 6h with the original FW.
With 2.38 it can cover a whole day

I am on the 0828 ezgingerbread. I have wifi sleep policy set to "never", because I need VoIP. This is a G1 with wifi on, sitting on the desk very close to the wifi AP, the battery drops from >90% to ~40% in 14 hours with almost no usage. I checked the battery usage and found "Wifi" used 60-70% power.
This is different from my previous experience with MT3G rom (froyo) also from ezterry, for that the battery drain was about half of that speed I would say, with wifi always on.
Do you also see the same high battery usage for wifi? Thanks!
I'm now with ginsense 2.3.7 from rushnees and i can tell you that it drains the battery.
As i know, wifi for a long-usage is better than 3G in the battery section.Ask to the developer about another kernel.
Wifi alway drain battery if you constantly have it on. If that how much the drain is, you are pretty good. My would drop to the point where I have to charge it.
I'm trying to figure out which idle setting is preferable.

In my experience for my phone....Idle on wifi is always better....3G eats lots of battery...2G is still better...thats why some people toggle 2g/3g........
Agreed - wifi mostly good for power consumption purposes

I've found that the biggest (idling) drain on my battery comes when the phone is constantly searching for 3G signal. If you have wifi available, use it.
I plug my phone in while I listen to podcasts on my commute into work. So when I get out of the car, I'm at 100% battery. If I put wifi on when I get to my desk, after 9 hours in the building, my battery is somewhere in the 78% to 85% range. If I leave wifi off, I'll be at around 50% to 60% at the end of the day. 3G signal isn't that strong in my building.
I've also been places with little-to-no 3G signal and no wifi. I lose around 20% to 25% of my battery per hour.
I love the CM7 build for the milestone, It makes the phone so much better!
but one thing is weird. When I use the 3G DATA (browse sites, watch YouTube)
the battery drains REALLY fast!
For example, today I got into facebook, browsed 4-8 pages, and the Battery
level Decreased by 30%! (FOR A 5 MIN SURFING)
Wifi surfing seems ok.
Is this normal?! anyone else had this problem ???
I have the same problem. using 3G data drains my battery drastically. been using the phone for more than 2yrs now. i wont complain about that. but CM7 is gr8 when it comes to boosting your battery life.
Same thing happens here and i think it's normal. 3G consumes more battery than wifi on every phone i had.
Active 3G consume more battery than Wifi (or 2G) but 30% in 5 minutes is not normal.
You should calibrate your battery with this tutorial : http://forum.xda-developers.com/showpost.php?p=11803458&postcount=10
Did you calibrate the battery after having flashed CM7?
I'm loosing a lot of batterylife when 3G is activated, too.
battery "drain" is normal on DATA. i had these problem too with my milestone.
wouldnt say its a CM7 problem...
for me it is because of the "2 year old battery" + DATA... those two wont work well
Hi guys.
I know there are million of threads very similar about battery drains, but I can't find a definitive answer.
On wifi I think our x8 works with no particular drains. But on 3g is very bad.
Only data, whatsapp and mail (every 3 hours update) on. Well, 1 hours of web browsing has been my maximum(always thalking about 3g). Is this normal, according to you?
I'm now testing Gingerdx x30, but I tried other roms with more or less the same results.
What about you?

3g should drain battery more then wifi. So its normal.

Even if I have 3g on in standby mode , battery drains too much imho.
3g Reduce the battery ..due to receiving large amounts of data transferring great performance, decibel
Hz, everything thin reduce it

Ok, I Understand.
What's your usage with 3g?
The 3G mode power consumption depends on the signal quality and the distance from the connected rx/tx station. With 2G mode too (this is normal), but the 3G range is much smaller than the 2G range (approx. half distance than the 2G). So, the power consumption increasing quickly with the distance. With weak signal the radio device working on max power, and the battery draining due the higher frequency (1800/2100MHz instead of 900MHz of 2G) Example: if my 3G signal is weak, my battery is burn like the hell (in standby too), if I go to the nearest rx/tx station (max. 3G signal), the battery burn faster than 2G, but the difference not significant. You can play with some RIL settings in build.prop, but you can't win extreme battery savings with these settings.

That is normal.
However, if you're a light internet user, I would definitely recommend you switch to 2G only. All the web pages and mails would take a bit longer to load, but you would do a lot to save your battery. You can do it from the settings screen if your ROM supports it, but if it doesn't, the code *#*#4636#*#* can get you there.
Well I'm testing 2x battery
Hi folks
Does anybody else also expierience such a huge battery drain on his One? It runs smooth and the battery usage is acceptable, but as soon as i turn on a faster network than 2G and surf on the internet, especially searching for things (loading data), it's using so much battery... I know that the screen is on and the cpu load is also higher while browsing and i was expieriencing this problem on my other htc phones, but it seems like a problem with the modem for me... it gets hot while browsing and is using more battery even when in idle
Is your phone rooted? Have you checked whether some mod or something is doing it? But if you want better battery life with LTE you can always enable fast dormancy if your carrier has that. But also if you have fast dormancy already enabled try to disable it because some carriers do not support fast dormancy. Best way to check, call them up. But over all I'd say that on LTE it should get a good 5-10 min per 1% battery drain. Hope I helped
