[Q] Is WiFi better for battery life than 3G? - EVO 4G Q&A, Help & Troubleshooting

Read a couple posts about this, but I would like to confirm if this is true with our EVO's. Is using WiFi better for the battery than 3G when it comes to draining it? If this is true, it would be nice since my work and house both have excellent wireless connections. Before, I always thought wifi would use more battery since the antenna is always on..

Yes
4,6,8,1

By far..like twice as good.

If it was 2x as good I could get 52 hours on a single charge! But that wont happen.

Okay maybe 1.5x good lol. It is faster AND better on the battery. How do you get 26 hours on 3g?

Im interested to know this too!!!

I just got 15 hours on Wifi..of course I was sleeping half of those hours but I got in some YouTube videos and internet surfing. I took it out with 8% though. My batteries last way longer when I use the external charger too.

AVA's ROMs give me best battery life. I never turn off data and best battery life was 27 hours on single charge. That was with less than avg use though. I typically get between 18-20.

What tweaks did you used?
impressive! mine doesnt last that long because im always on xda from phone, texting playing games and streaming google music which takes alot...etc....
does eagleblood provide better battery use compared to stock (rooted with bloat removed)
I'm on EB too & batt life is pretty great. I'm a pretty heavy user(BT streaming for 2-5 hrs a day, up to an hour of phone calls, hour or two of web surfing, and hundreds of texts) & I can still make it all day just fine on a single charge. I think it's partly the rom but mostly that our phones just have damn good batteries. Even on stock I got good life.
Holy crap!
that is a major record !

No, you should just use it more . Of course you will get great life if you don't use it for hours.. lol

Did you notice the 5+ display time? That means his phone screen was on for over 5 hours, check your screen time and it'll likely be less. Overall he actually had his phone on quite a bit really.
Why does it say your battery is at 45%? Are you using an extended battery?

Huh. Good pickup. The battery icon says 45%, but the battery graph indicates < 10% battery. Things don't add up... which usually means BS, but we'll see what his explanation is.
pcmanager's screen shots seem like the real deal though.

Longest amount of Up time on your E4GT?

I'm currently rocking 313 hours, 28 minutes since the last time my phone has rebooted.
If you are a flashaholic, your up time probably never exceeds 6 hours
Before I rooted the Device I had 3+ weeks without reboots. Lately however I've gone back and forth with a few roms so maybe 2-3 days. at one point (even though it was not this phone) I had 843 hours on my old MT3G Slide on T-Mobile (rooted)

Don't really care about time between reboots, but my record uptime is just over 31 hours, calk 2.8.1, rogue hitman oced to 1.504 conservative. Using 4g, even.

Damn....31 hours overclocked that high? What was screen on time? If you got anything over a couple of hours that's impressive!

The only time I've had to reboot was flashing or making changes to the system.

Can't remember exact screen on time, but it was under 2 hours. I did however download a ton of stuff on 4G trying to get stuff working on my view. I always have low screen time now that I have my widgets all set up. Phone comes on, g reader and facebook checked, phone goes off . Mostly use the tablet for xda now.

LMAO at this thread. It reminds me of the old Blackberry days. Those memory leaks were deadly...

my T999 has been giving me pretty bad battery life.

80% in one hour. its ridiculous is it me or the phone?

Need more info, my guess is a background app. Looks like you are stock 100%? That's your problem, lol... Just messing. What is your screen time? Click on display to see that... You're in a 4g area so signal shouldn't be the culprit. Your media is #1 user, but why, were you using it?
More like an hour and a half close to 2..if you used it for like 20 to 25 minutes I would think it's common. Like dude said above me we need screen time, also data technically eats battery away faster than wifi just a thought. Brightness is important too maybe you can try power saving mode, don't expect much difference though. Darker wallpaper helps, but most importantly are you auto syncing and if so which apps it usually starts there. Every little bit helps, most powerful phones have average battery life. Unless you start undervolting voltages and cpu that's where you see the big difference.

Has to be a rogue app. Try wiping the phone and reinstall everything with increments to get to the root of your problem.

100% awake time, horrible battery life.

Okay guys, I hope this phone gets better battery life than 8 hours, and I'm not hard on a phone at all. Any ideas on this? My wake locks are horrible for some reason and I'm running the synergy r71.

Install BetterBatteryStats. Great tool for identifying what's killing your battery. You may post some screenshots if need be.

Deep sleep battery will help alot as well your at 49% so if you think of it by the time you are drained to 10 youll probably have about 18+hrs of battery

Yeah alot of people freak out when tbe phone gets to about 50% they don't realize that thats half the day usually. ... and it also depends on how long your last flash was it takes a few days forvthe kernel to settle.
