So, it seems the default policy for wifi on this device is never to disconnect itself to save power. The Vibrant defaulted to whenever the screen was off. That makes the default wifi policy between these two devices vastly different. In fact, there isn't even an option on this phone to disconnect from wifi when the screen is shut down. I wonder how this will affect battery life. I may think twice about enabling wifi.
The first thing I did after connecting it to my wifi was go to the wifi advanced settings and set the sleep policy to never. I'm glad it was already off by default. It shows that someone at HTC paid attention to that small detail and how it affected battery life. It greatly helps your battery life in my experience (with the Vibrant), since it's not constantly connecting and disconnecting from wifi which apparently uses more power.

Really? How would that *improve* battery life? I would have it to *detract* from battery life. If I'm at home basking in my wireless network, why would I rather have the connection permanent than to have it disconnected when the screen shuts off as it does by default with the Vibrant? If what you say is true, then setting the timeout from the 15 minutes timeout, as I have it now, to full time connection (never timeouts), will actually save on battery? To me, that flies in the face of reason, but then again, stranger things I've come across.
Just hoping for a reply to the above, and perhaps someone can explain why having wifi never time-out even when the screen is off can lead to better battery life?
think about it. having to connect and reconnect everytime you turn on your screen is bound to eat up. if your screen is off its not sucking in massive amounts of data so the battery drain is at a min

Well, it's certainly not intuitive, and I am thinking about it, hence the post. In order to maintain an active wifi connection, there has to be continual pinging back and forth even with no active data connections from the device. Now, we all know that there *is* a lot of data being exchanged when the screen is off - whether it be syncing accounts, retrieving news items, emails, etc. This would all be taking place over a wifi connection by default. It is also my understanding that using your wifi radio consumes more power than your UMTS radio does. However, I'm not entirely sure of that last point.
Isn't it far more intuitive to believe (whether factual or not) that having the wifi radio powered on unnecessarily while in your pocket would consume more power than having it turn off? Even the seasoned users over in the Vibrant forums all recommend setting the wifi to turn off when the screen shuts off, which is a setting not available on the MT4G.
I'd like to believe that how HTC sets the default wifi behavior conserves power, but it sort of flies in the face of reason. I'm also of the belief that the device is set by default the way it is so that callers who use Wifi Calling can always be reached while at home on their wifi network. But, having such a wifi connection setting is actually eating up your battery life if you don't need wifi calling.
Wifi used less power that edge/g3/4g. Having it constantly on wifi with improve your battery life just because when wifi is enabled it shuts off cellular data.

Ok. Android phones are not blackberries, and I'm well aware of that. This Thunderbolt is not my first android device, so I am very familiar with setting it up and using it in such a way to make the battery last.
I'm not posting this to complain of the battery life sucking. I'm complaining that the battery is fine one day, and horrible the next.
So here's what happens. Yesterday, i unplugged my phone at 730am like i do every day. By 3pm with light usage, i was down to 40% or so. Charged it up before I left work, no big deal, lasted the rest of the night.
Today, unplug the phone at 730am, phone is completely dead, as in, won't even boot by 11am. Same apps, same usage, same location, same strong 4G signal, same everything. It has happened multiple times on consecutive days when i was rooted on the stock rom, and still on VirusRom. I just dont get why this happens. I am doing nothing different and my phone either lasts all day, or a few hours. It's getting to the point where I am finding it very hard to rely on this phone when i'm out and about. It makes no sense. Especially if i'm not really using my phone, just checking for texts once in a while, there is no reason why it should die. What if i need it? I couldn't even call or text my gf tonight while I was working because my phone battery was ZERO only a few hours after leaving the house with a 100% charge.
Is anyone else experiencing this?
yesterday I had abnormal drain on my battery. I get 18 - 24 hours on a charge normally, but yesterday I went from 100% to dead in 5 hours. Called VZW and they said it was a documented problem and they were working on it.
IDK, they are pretty good about pushing updates. Also, yesterday I kept dropping out of data. bizzare....
I burned through the extended battery in 9 hours yesterday, really hope they figure out some better power management soon,
Switch it to 3G cdma rev.a and see if that helps. The 4G radio is always being searched for. I love the tb so I can deal with no 4G til they get the bugs out.

You have to use current widget and see how much power draw your phone is pulling. Then use system panel monitoring to track apps using the highest CPU.
Definitely an issue and I'm glad that Verizon is aware of it. I've had this unusual drain happen four times now, all on 4G. Last time I noticed it (seeing the battery percentage drop like 2% every five minutes or so), went to the Market and snagged System Panel.
The offending process is "system." Had my CPU spiked at 100% for over an hour before I rebooted, which does fix it, at the cost of another 10% of your battery, of course.
Hope they get this ironed out soon. Love my Thunderbolt, but this is a major issue and seems to be happening to a lot of people.
The best thing to do is dial *#*#4636#*#* and turn the radio to CDMA auto (PRL) mode.
I am already seeing much better battery life, as I am in a non 4g area.
Thanks for the suggestions. I'll have to give that a try. I got into the radio settings, and after flashing VirusRom, my phone defaulted to LTE mode only. I put it to cdma/lte auto, to see if that helps. If not, i'll just disable LTE unless i really need it.
No need to dial all of that crap. TeamAndIRC has a toggle app called "LTE OnOFF TeamAndIRC" that allows you to toggle between CDMA and CDMA + LTE/EvDo auto.
I found out two things dealing with my massive nighttime battery drain. One, wifi doesn't seem to work correctly. I've never had the problem before but for some reason it doesn't sleep correctly. What I've done is changed the sleep policy to "15 minutes" which allows it to switch back to 3G fifteen minutes after I turn off the screen. That allows me to have wifi while I'm using it but 3G while it's idle. This has seemed to fix my problem along with... Second, I am on the fringe of 4G/3G here on the outskirts of Cincinnati. At work I am solid 4G but at home it can't make up it's mind. Well, that has certainly played into the battery issue as it is constantly searching. So, what I do is as I walk in the door from work I use the app listed above to switch to "CDMA auto (PRL)" and it sticks to 3G. When I get to work I switch to "CDMA + LTE/EvDo auto".
So, to summarize:
I have eliminated my nightime drain by doing two things:
1) I use the Y5 app to automatically start wifi as I walk in the door but have changed the sleep policy to "after 15 minutes".
2) I use the app above to switch from 4G/3G auto to 3G only.

LTEonoff is just a shortcut to the menu. In essence, it saves no time because you have to download it. If you're flipping it on and off all the time, then yeah, it might behoove you to just dl the app. But, as a one time thing, it's unnecessary.
^You are correct. I switch daily but I didn't see earlier that you were not in a 4G area.
I would highly suggest this to anyone who sees their data connection switch back and forth as I was in my house.
Battery life has been strong the past couple days now. I haven't had any unusual drains since i switched from LTE only mode to EVDO/LTE auto mode. I dont know if this was for sure the issue, but it seems to have made a huge difference. I haven't been plugged in for 2 hours and i still have 92% battery left.
Here's my interpretation of the issue:
There seems to be some kind of problem or bug with the radio which makes it drain an enormous amount of power from some towers (700mA+ is shown on current widget). Even with good signal, I'll repeatably drain a lot of power in certain areas. The "fix" is to disable mobile data or switch to wifi. This lowers the power usage back down to (slightly lower than) normal levels.
For some reason, the radio will not admit to drawing practically 90% of your battery in the battery use menu (nothing does, in fact ... it just looks like normal battery use).
I'm glad to hear that they are aware of an issue that maybe causing this.
I can't stand the battery life either other than that I love the phone

Yeah i'm still at 83% battery after being unplugged for 4 hours, light usage.
Another thing i noticed is that when my battery was draining stupid fast, the phone would be warm to the touch even when it was just sitting on my belt clip. All seems well for now.
Mine is good

My battery life has recently become terribly inconsistent. Last week I was actually getting through a 16 hour day with light usage, but this weekened I must have installed something because now the phone is lasting 3-4 hours with hardly any usage at all.
The battery information is pretty worthless because it's not showing anything except display using the battery and the display has only been on maybe 8 minutes.
Checked the partial wake info and nothing seems to be running in the background. The battery is just discharging like crazy all of a sudden. Guess Ill start uninstalling stuff to see what might be causing it
I am also having a weird battery experience today. I am rooted running Adrynalyne 1.9. Last few days I was doing great, moderate usage and was staying charged for 16-18 hrs. Today my phone has died twice during my 8hr shift at work. I KNOW something is wrong there. Hopefully a fix is found soon.
On all my Androids (4 of them currently in daily use), I've found that Words With Friends is often a HUGE battery killer...and I don't mean because you play it a lot, I mean leave it running and put your phone down, walk away a while, come back to the phone and it is HOT to the touch! Obviously killing the battery. Something to look at for sure.
I've got the extended battery and just went over 48 hours, with moderate to heavy use by my standards on a single charge. Pretty amazing and I guess I'm not in a bad radio area.

The only thing I love about the TB is the 4G...everything else on it, been there, done that. I wouldn't keep the TB if 4G had to be turned off to make it usable in terms of battery life. Hopefully it will be fixed quickly!

Thanks for that analysis. With that in mind, if it's accurate, could a Tasker app profile be set up that does your fix if the drain works that high? Would be a nice safety feature for those who aren't willing to have to look at their phone frequently to check battery life.
You have to use the current widget to record your idle power readings, its the only way to know what's going on. Then use system panel monitoring to see which app CPU is highest.
From a battery perspective, should I use wifi? Most of the time i'm at home or at work where I have wifi. I also have good lte coverage at both. Speed aside, will I save battery by not using wifi or not?
You'll definitely save battery by using wifi when you can connect. I love the speeds over lte, but it is definitely a hog...
i also had boost of battery using WIFI
Using unlimited data plan makes me to consider using 4g, but I found that Wifi consumes much less battery.
Use wifi. The battery savings are huge.
yes i cant stress enough, wifi saves enormous amounts of battery so use it when ever possible. the difference is like night and day.
Compared to 3G
I've been leaving my wifi off since I have unlimited data and the 3G is pretty fast in my area, no 4G yet.
I've had pretty good battery life lately using only 3G, I'll have to do a few tests and see which one and I'm a fairly heavy user I'm approaching 4GB this month and none of that is tethering
3G or Wifi
Tested watching a streaming video of 22 mins
on 3G I lost 13%
on wifi I lost 8%
Wifi wins, of course standby is probably different, if 3G vs wifi loses this badly I'd have to imagine LTE vs Wifi is a slaughter battery wise
Actually I found something interesting...
For some reason, even when I am home using Wifi, the battery drains faster than I thought. Where I live is like a strange signal spot. If I turn off my WiFi I can see my TBolt constantly switching between LTE and 3G, sometimes it stucks on 1xRTT for a while then goes right back to switching between connections. If I am at work (downtown LA) where the LTE is pretty well covered, I still use WiFi at the office, the battery BARELY drain at ALL.
My theory is that even when WiFi is active, the phone somehow STILL does the LTE/EvDO switching on the background does draining the battery.
If somehow the devs or VZW can tell the phone to STICK to EvDO/1xRTT instead of going back and forth with the LTE while WiFi data is on, it'll solve the problem.
Also just FYI, I have the latest radio and BMAF 1.5 remixed.

pretty much correct. at least on the gsm side, when i connect to wifi at home, i can no longer see if the phone is on 3G or EDGE. but it definitely switches back and forth to those networks, while staying on wifi, you just dont see the icon switching, but its definitely happening. i dont see why cdma and 1x would be any different.
if this is the case then why don't you just turn data off when you are on wifi.

Better yet get juice defender and automate it . Its very good app. Right now it says I'm almost adding fifty percent on to my battery.
I seem to be bucking the trend here, but LTE is working better for me than wifi. I usually have a good signal, so that's part of it.
The other part is that my wifi may be eating more juice than normal because the TB and my router may not be playing nice together. Ever since I added the TB to the network, I've had to reboot the router every coupla days. Before the TB, it was solid weeks on end.
Has anyone who is still having trouble on with batter on wifi set their wifi sleep policy to "Never" sleep? Mine is set to this and if I am home most of the day I will lose very little battery through out the day.
I believe by default the wifi is set to turn off after a period of time or when the screen is off so during this time I believe you are actually reverting back to using the vzw network. To turn wifi to always on go to settings>wireless>wifi settings>hit menu>advanced. The sleep policy is at the top, change sleep policy to never. This my reduce battery while not connected to wifi so I always use the power control widget to turn my wifi off completely while I am away from the house.

Oh yeah this is very important, set wifi sleep policy to never greatly increases battery life. Otherwise it switches back to 3g when screen goes off and drains way more battery. This is very important to set this otherwise you wont see the increase.
Is strongly recommend switching to cdma only if yore gonna use WiFi and plan on saving your battery. Otherwise what's the point. I personally don't even bother using WiFi just use LTE only mode. I'm getting better speeds than most WiFi connections using my LTE.

If your connected to wifi and using it, are you gonna get better battery life VS being connected to either 3g or 4g/hspa+?
and Why if so?

This is the General forum. To answer your question, Yes it would use less battery on WiFi. On a data connection the signal is not a constant and the phone is always looking for a stronger signal.

yes. And 4g eats your battery.
When I am only using the phone for data, I use WiFi when available. I turn on airplane mode then activate WiFi.
I don't know about that... when I'm on wifi my battery drains like a mofo. Weapon 3.0 ICS theme faux 1.3 kernel.
On every ROM and Kernel I've tried, Wi-Fi uses much, much less battery than 4G. I haven't tried any of the toggles / battery saving apps though so I'm not sure what effect those might have.

He shouldn't have to. If he's draining faster on WiFi then something is screwy with his setup.
On stock, cyanogenmod 7.1, and cyanogenmod 7.1 with various other kernels I've experienced increased battery drain with wi-fi on and connected with the phone sitting at home the entire day. Turn off wi-fi and let it just use the data connection to T-Mobile and I get drastically increased battery times. I'm assuming those of you who get better battery with wi-fi on are in extremely bad signal areas. Also, if you're on cyanogenmod have you turned off the auto wi-fi disconnect when sleeping feature? If you haven't then your battery life when sleeping should be the same as that of wi-fi turned off.
Wi-fi should always be priority if your in range.
Well my personal experience has been that wi-fi eats up battery like crazy. Same thing happens to the other smartphone users I know around here so I was surprised to see that people get better battery times with wi-fi on. Are you guys completely turning off your cellular radio? I don't like the quality and slight delay of wi-fi calling so my cellular radio stays on when I have wi-fi on.
I don't usually notice much difference between wifi and 3g battery drain here (no 4G for tmo here).
As someone already posted, my drain is worst when 3g signal is poor, like when I'm at work and the metal building interferes with everything.
Have you tried checking logs while connected to wifi to see if maybe some app or service goes crazy?
Nothing fishy going on when wi-fi is on. I get about 10-14 hours on battery with wi-fi on and next to no use of the phone vs somewhere around 20+ hours with wi-fi off and similar extremely light use. I keep meaning to do some more standardized testing where I literally don't touch the phone but life gets in the way and I have to make/answer a call or txt or whatever so I can't nail down any hard numbers. Typical experience on a slow day for me is that if I forget my wi-fi is on, my battery will be somewhere in the 3-5% range when I'm getting ready for bed while if I hadn't left it on, I can go to sleep and wake up and it'll still be hanging in there.

That's true, I've always believed that Wifi eats battery faster because someone(don't remember who) always told me that Wifi uses more battery because it processes data faster, but I always noticed that when I used 4g, it drains a lot faster.
I always blamed it on the ROM, but I can see that it's not the ROM's fault.
Anyone else experiencing this? Atrocious battery life post upgrade. Nothing odd running in background, program or processes. Rebooted phone. Started the day at 100% with moderate usage at best, I'm already down to 19%.
Battery life is relatively unchanged in mine after the mm update. Easily make it through the entire day with 50-60% battery life remaining. I disabled a whole bunch of the bloatware (and will be removing it entirely when I decide to root my phone) and battery life is wonderful.

Mine has been fine, slightly better with doze/disabling packages. Do a back up through Smart Switch and try a factory reset. I do that every time I update.
I'm envious of your successes. I'll give it a bit to see if it stabilizes, if not I'll use SS and reset/restore.

I will recommend "Package Disabler Pro" to disable bloatware. Costs but is worth the cash.
Mine went through on Thursday and so far battery appears ok.
I have noticed however the lighting is messed up all over. Play books night light feature is broken and dims it to unrecognizable levels. I have to go into the settings again when in the book and disable auto lighting and manually raise it. When back at the list of books screen, the brightness drops to nearly off again.
Also it seems the notifications when listening to music are much louder. I could listen to mp3s via poweramp while reading a book and get an SMS text and itd be a light little sound. this is playing louder than my music and very annoying.
My batter life was horrible after the upgrade. Here's what I did to fix it.
1) Wifi sleep policy - Changed that to "While Charging" (big difference noticed after that)
2) Fully charged phone then let it run down to 0 (must let it power itself off)
3) Wifi Scanning has been moved under Location setting. Go to Location -> Improve accuracy, make sure Wi-Fi scanning is off.
Batter life is awesome now.

1: Apps/sync will use mobile data as priority if this is done while waiting to connect to wifi. In turn, using even more battery if an app/sync wakes the phone switching between networks.
2: This is damaging to Li batteries. To extend the life of your battery, it is better to keep it topped above 80% and cool(not very common in real world applications). These aren't Ni batteries, long gone are the days of "memory discharging".
If you don't need notifications at night, use airplane mode. I miss Xposed, Autotasker, and Amplify(formerly Bounce)... Greenify is a good alt atm
Note: Sometimes even Play service updates will introduce bugs and or "retarded" policies that will destroy the battery, especially the "Now" systems. It can happen at the most random times as well and not at all most. Every now and then the fat man will get stuck in the tube.
All thoughtful replies. I don't have Location on ever, unless I'm using Waze, so that's a non-issue for me. Allowing WiFi to sleep when the phone is off, while I'm only connecting via WiFi, effectively makes my smartphone a dumb phone, until I wake it up, right? The fact that I need to start changing around "normal" settings on my phone, to lesser benefiting ones, to get back to the battery life I had before I installed MM is pretty silly. I've been hoping things would settle down, but they don't. I can try using SmartSwitch later to see if that helps.

No, it will connect LTE and then switch to wifi. LTE use more battery life, the network switch uses a bit, then finally you are into wifi. If your phone wakelocks or alarms(location ping, play service ping, etc) it will use more battery than wifi always on. Personally, I've tested both to make sure a wifi wakelock bug hasn't been introduced as I do with every update and play service update(it does happen and it's horrible drain). I see more savings always on.
If you meant you disable mobile network, yes, dumb phone, text and call. Also, I disable mobile usually always as I piggyback off work cell at work, and always wifi at home. I only toggle mobile data when necessary.

My batter life was horrible after the upgrade. Here's what I did to fix it.
1) Wifi sleep policy - Changed that to "While Charging" (big difference noticed after that)
2) Fully charged phone then let it run down to 0 (must let it power itself off)
3) Wifi Scanning has been moved under Location setting. Go to Location -> Improve accuracy, make sure Wi-Fi scanning is off.
Batter life is awesome now.

I believe this is what most people encounter. Most dont have unlimited data and use WIFI always. I think by default, WIFI is set to always on, even when phone screen is off. WIFI will rape your battery. I did my own tests with wifi vs 4g and just by using my 4g all the time, battery quadrupled. Many argued that WIFI uses less battery, and i have the best of the best wifi router/modem/isp with 5ghz ac excellent coverage. Not the case for me. I have unlimited and just stick with that now. Battery life on MM has been great for me.
My battery life is 4x better. I couldn't be happier.

Anyone else experiencing this? Atrocious battery life post upgrade. Nothing odd running in background, program or processes. Rebooted phone. Started the day at 100% with moderate usage at best, I'm already down to 19%.

Been on MM for about five days now and my battery blows, so much worse than what it was!

Mine is exactly 4 times worse
Battery the same.
But I have to tap the screen harder to chose app.
Going to factory reset and start clean, been a while.

Not that I know of.
Though they JUST released Marshmallow. Verizon is probably still patting themselves on the back even though they released several months late. What I'm waiting for is a miraculous root.
I never use my phone the same amount every day, so it's hard to say exactly what kind of battery life I get, but I have noticed that it has improved. I would usually be near 15% by 10pm after coming off charger at 6am. Now I float around 25% at 10pm. So it seems to be better, even if only slightly so.
I see a minimal improvement, but I was doing what I could without root prior to sleep unnecessary crap.
Weird, when thye MM updated happened, up until the last two days, I was getting much better battery life under MM. But the past few days my battery life has declined dramatically to the point that I am not getting through a day of minimal use. Screen only 2%, Android OS consuming 76%.
I just fiddled with settings (Changed Wifi sleep to While Charging; Turned off wifi scanning). I am going to also try a reboot to see if that helps. I swear it started just about the time I started looking at Nexus 6p replacements).
Update, rebooting, and removing a few more useless apps and battery life has returned.
