[Q] Wifi v 3g/HSDPA on Battery

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

[Q] Cell standby eating 60% of battery.

Hello,
I'm on Serendepidity 6.4 and disabled both WiFi and 3G data connection over night on my Captivate. In the morning 40% of battery is gone (8 hours later), out of those 60% is "Cell standby". I'm in 5 bar area and time without signal is "0%". What can be causing this?

Bad flash, bad modem. what modem are you on?
have you reflashed?

Modem is JK4. This is all standard with all Serendepidity users. Would not bad flash would mean unbootable device etc? Not just big battery drain from cell standby?

a bad flash doesnt neccasarily just mean an unbootable device...that happens when the bad write occurs on the kernel or major part of the firmware...but can happen at any part of the process. causing issues inside the OS...
that being said i believe users have seen this bug acrosss all GB roms(although i personally havent come across it)... the solution is to pull the battery for 5 or so minutes and put it back in.

[Q] Wifi uses battery >60%, is this normal?

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.

[Q] Is phone awake when automatically looking for a network?

Hi, I live in a place where there's very poor network coverage and my SGS often looses signal. And here's the problem: when I check battery consumption in the settings I can see that the phone is often awake (for about 1,5 hour overnight) and looses battery like 3% an hour even when I don't use it and is supposed to be asleep. Is it possible that it is searching for available networks during that time and that is why it is awake and eats battery?
I do not have data on, nor wifi or gps. I'm running SLIM 3.3 with 0.67b Devil.
Thanks in advance.

[Q] up to 1% battery drain per minute on cellular data (3G, H and LTE)

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
