Well, I am not complaining. I am surprised and I am here to share with you all my battery backup.
I have last charged my phone 4 days back and I still have half of that green bar left.
Its been some 8 months or more that I am using my phone and the battery backup never lasted more than a Day. I use to charge every night and the battery use to drop to less than 25% by the late night. I didn't panic though. I use to read about others experience on the battery backup and given the features and usefulness of the phone, i have no regrets what so ever.
I didnt upgrade anything on my phone including the ROM,
But I am quite surprised that its been 4days that I last charged and the battery is still at 50% and my usage didn't change a bit.
Am I going to get the backup that the HTC spec talks about?
Guess what? my GPRS is not working for some reason since a week now and i believe that is helping the battery. When the GPRS was working, it always use to be on air and even if I disconnect, it reconnects and stays that way because of automatic email checking.
But if it is really the GPRS, how do i live without that when the device itself is build for messaging and emailing? How do I optimize this?
What do you think ?
What "battery backup" are you using? Is this an external battery pack that you plug in?
No stevens, i am using the default battery that came with the HTC.
By saying Battery backup, i mean the standby time.
In diamond tweak you can choose to disconnect your data connection after not using it for 10 sec. through to 10 min. Try this, works just fine on my TP.
pointless thread please delete
of course the battery lasts if the radio is turned off
Automatic email checking uses a LOT of power so it is not wonder your battery lasts longer when it is disabled.

I'm not talking about turning the radio off, I'm talking about turning data connection (GPRS, EDGE, UMTS, HSDPA) off. It's a different thing mate.
also turning off 3g will make the battery last longer since it doesn't constantly look for 3g signal
as the guys here stated, as long as you turn off (or that they're off by default) the data connections and gps,your battery should last a good amount of time.
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.

I've tried to take out the Sim card, and after 13hrs of normal use, mostly connected to wifi, my battery shows 67% remaining.
But when I put the Sim card back in, still on wifi, I don't even use 4g, still same usage, same location, after only 7hrs, my battery is at 35%, it takes so much more battery to receive a phone signal then surfing the Web or playing games, is it my phone that have a problem or is it normal?

7 hours to 35% with the phone mostly idle is a problem though. In that period of time I lose less than 10% in good signal and 20% in bad signal on Serendipity VII. CM7 would drop by 15-25% at most. (Not TO 15-25%, BY 15-25%, i.e. not going below 75%)
No clue why - probably a rogue app. No details as to which ROM he's using so I cant give more tips. If Gingerbread, Settings->About Phone->Battery Use can sometimes give useful info.
Will the phone have a longer battery life if the cell modem is set to 3g vs lte?

Yes, in my experience with the S4 it's a pretty big difference UNLESS you get a very strong LTE signal. I'm on tmobile and now have the N5 and use the 3G setting which is HSPA/+ Plenty fast for me for what I do. When I want some extra speed I'll kick on the LTE
Does anyone have a more detailed answer for this? I just got this phone yesterday so I haven't been able to find out myself yet, just with 5hour battery life from 100% to 4% on what will only be half of its normal day I'm looking for anything to help right now till I get a battery case. This phone is one of only two to have a LTE radio that is supposed to use 30% less power than usual so I'm wondering if that makes it as efficient if not more than 3G for idle in your pocket to light stuff like FlipBoard.
it would depend on the quality of the data connection. im in brooklyn nyc, and use lte on my nexus 5 exclusively, used to use it on my nexus 4 as well. with 3g(hspa+), on both my n5 and n4, i average about 4-4.5 hours screen on time. when using lte, i average about 5-6 hours screen on time on both my nexus 5 and 4. after noticing this difference, i use exclusively lte on both my devices, as i average an hour more screen on time when using exclusively lte.

Serious battery drain can have many reasons. One is having LTE on, syncing on(if you just booted it up, and input your Google account and let all your apps sync and download, its gonna drain your battery fast the first time), having locations on and wifi enabled. If you are in an area with poor reception, your phone will drain more trying to find connection.

Thanks for the information. That's what I was wondering but I couldn't find anyone that had already tested this with these new radios. If I get the time this weekend maybe I'll do my own test in detail to compare LTE to 3G. Am thinking of using a TV episode on Netflix and see which makes the battery drop faster over the 30 or so minutes.
Slightly off topic, does anyone's WiFi show as always on in the battery monitor even if its been off? Still trying to figure out my battery drain issue, if it even is an issue with just me, I bought this phone knowing it had a small battery.

Seems that's a whole other debate on weather leaving that on or turning it off helps battery life. Apparently if you turn it off then apps that want your location will turn the GPS on and waste battery (looking at you Facebook...), but if you leave it on the phone just tells the app your location from WiFi networks around you.
One thing I didn't think about is I had added my work WiFi yesterday but it wouldn't connect to it, wouldn't tell me why but I'm assuming it's because of bad signal as I'm a valet outside and the WiFi is from a bar across the street so I forgot about it but WiFi was left on with that network saved, my Nexus 7 can connect to it on most days and any laptop has no issues but with this being a phone I guess it doesn't have a big enough antenna. So I'm wondering if now that I deleted that WiFi network, and I always have my phone set to not notify me of public networks, if my battery won't die so fast today.
And now I'm just rambling but I just looked at my screenshot I took yesterday of battery use before plugging in at 4% and WiFi isn't even being shown on top six things that used the battery, lowest one being shown is a Chrome process using 3%.
EDIT: Well off to work now with my phone 100% charged, will have screen 100% (am outside in the sun), BT off, WiFi on (disconnected, no saved networks nearby, open network notifications off, always on during sleep, scanning always available, avoid poor connections, and WiFi optimization), LTE on/connected, NFC off. So lets see how things go. It will have tons of screen on time as all I do at work is read through FlipBoard, then if I run out of things on there I move to FB. Lets see how this goes...

Sorry for digging up such an old thread, but with LTE my Nexus 6P, it switches between HSPA and 3G. When turned to 3G, nothing changes. Would that mean I would save battery?
