Are we likely to see a fix for this? We know there is a problem with 3G drinking battery but how likely are we to see a fix. Solutions like disable 3G aren't viable for a lot of people, so I just wondered what peoples thoughts on this were.
Try changing your modem. You should see a slight improvement in battery life, nothing major but still better than nothing.

Yeah a modem did help but I still had a big problem. Are we likely to see a fix, I remember this being a problem with ICS which is why I reverted back.
Its not the modem. My phone stock uses the XXKG3 modem, and i have been using that on ICS and now into JB. Jellybean definitely has worse battery concerning 3G / H for some reason. I just barely squeeze a day out of mine.
Yeah, I was struggling to get even a day. I tried almost all of the Jelly Bean ROMs and they all suffered from the same problem. I really wanted to stick with JB, especially C-ROM because it was like a dream to use but on a good day I'd get about 7 or 8 hours maybe? I would always have to plug it in twice a day. Currently trying SauROM which is better but I'm starting to think that the best for battery life is genuinely a stock rom like JVS.

did you limited your speed to 3g or do you also use hsdpa? if you use hsdpa, give 3g a try i think the battery drain in 3g is a lot lower ... in my opinion if you are not downloading 3g is fast enough to browse or youtube.
for just instant messaging you can give 2g a try
2G isn't really usable on Three mobile.
I don't know how to limit to just 3G. But yes I normally use HSPDA. That said, we should be able to use it without draining our battery
I'm not getting any major battery drain here. I can last a full day on HSDPA and or WiFi.

You CAN limit to just 3G. You have to go to Advanced Settings or Galaxy S Settings (depends on a ROM) and go to HSDPA and put it to UMTS mode only. It'll switch it to 3G and will consume less battery

in my opinion, thats the point, go to settings/advanced/RADIO in your case hsdpa + hsupa should be ticket, simply tick umts an you should notice, the changing radio icon in the status bar (no longer h, but 3g).
your 3g and hspa power consumption depends really strong from the signal strenght and in your phone is connected constantly or changes often. bad reception causes a large waist of battery power.
My guess is you have Google Now / Maps running in background which always uses your data.

On slim 2.9, I found that removing G now, and turning off all location tracking increased battery life. Now I can get a day and about an hour/90mins of screen on time with data/wifi only on when using it. I suppose after more than 2 years of use on the one battery charging every day or more, there's only so much one can expect from a device and battery.
But isn't it recognized that this is a problem? The 3G Bug? Nothing to do with Google Now etc

in my opinion thats not enough, do you mean 24 hours or 16 hours? could be a little more with 90 mins of screen time, but you shouldnt need more.

Sort of... 3G uses less power than WiFi in some ways, and more in others...
In general, WiFi uses less for data because it is faster and thus spends less time fully charged up. But 3G uses less power when charged, but at slower speeds, so it ends up using more... ie, WiFi uses, say, 3power x 1sec=3 where as 3G uses 2power x 2sec=4.

3% screen usage? Did you even use it at all? next time can you include the usage for each of the items listed in the list? would be helpful for comparisons
40 hours only?
I reached 3 days with this kernel meaning 72h and yes I used wifi,market,camera,sms... but all in light to moderate use.
My N1 is 5 weeks old so perhaps the battery cycles are beginning to make it last more too.
The minimum battery I have now is 48h when using ''Men's health'' app for an hour (lot of screen usage) while at body building.
I wonder if GPS will eat battery too fast

Are you sure you only used it for a 30 minute voice call? There's definitely something fishy there, it isn't normal behavior. If you have 3G on and you're in a place with bad reception a lot, or you have screen on (especially with max brightness), it can take up a lot of battery.
Install something like Spare Parts from the market which can show you battery usage history and use it to check whether you have any rogue apps running. If there's nothing suspicious there, you probably have a faulty battery. Any games using the rotation sensor even when they should be closed take up a lot of battery.

Well I'm in Manhattan, NY. Even though my signal is very strong outside(-51dBm) while in door its around -90dBm to 111dBm. SO I guess that could be a slight cause. I have it my phone on "gsm auto(PRL)" which has help. I also have the brightness on AUTO and everything else I do with this phone like texting, reading and the occasional browsing does not pass 20min. So a total of hour.
Now even after a fresh charge I loose 10% in 5hrs without every turning the screen on. This my second swap and I have 3 batteries. They all do the same thing. I just installed Spare Parts, lets see how this goes.
I have original stock rom unlocked
and currently it's been on 18 hours and I still have 77% battery left!
Hi all,
Now I've not tried this myself however a friend of mine who recently got a DHD said he was lucky if the battery lasted a day on a full charge however by turning "Data roaming" off (even though he is not roaming) he is now getting anything between 2-3 days on one charge
Data roaming was turned off by default on mine and still the battery drained pretty quick.
Using data of any kind will affect the battery badly. Notes Traveler on my device is the cause of it needing charging every day.
Same as any phone, the more you disable the longer the battery will last.
If everything was implemented correctly by HTC, turning off Roaming should have no impact on battery life at all (provided you don't use Roaming).
I believe that your friend experienced the typical warm-up phase. For some (a lot?) people the battery life is terrible when they first use the DHD, but it gradually gets better.
Your friend probably attributes the increase of battery life to the disabled Roaming, while it is just a "natural" process.
I'm roaming all the time, and my battery is actually pretty good. If i don't use it much it can easily survive two days. My record is three days with light usage. (That was with the stock 1.72 ROM)
What is data roaming anyway???
Sent from my Desire HD using XDA App
Data roaming is set off by default. And data roaming controls data transfer when you are not on your home operator/network, i.e when traveling.
are your friend meant data connection?

He probably means "3G" off? I've had mine since the end of October and got into the habit of charging the phone every night. But then wondered about the effects of turning off wifi and 3G as, currently, I'm at home most of the time and have a PC with 24" screen to play with. Anyhow, with 3G and wifi turned off most of the time I get 3 days or so from a charge. I haven't investigated turning just one or the other off as life's too short ....

If I meant 3G then that's what I would of said. So just to be clear, there is an option "Data Roaming" that when turned on will enable a data connection when you are in another country. My friend claims that while on his home network he has turned this option off and he has seen a big improvement on battery performance. If this is true or not I'm not sure, I just simply thought I would share his thoughts with everyone else.
I did this, once i remembered where it was and I got my old battery life back. So thats a bonus, not having to take my charger to work!

I have read some disturbing reviews about the Thunderbolt which is a 4G LTE Verizon phone. Although the phone itself sounds great, what concerns me are reports that the battery life is around 4-5 hours with 4G turned on.
So my question and concern is, once we upgrade the Xoom to 4G when available, are we going to be victims of the same poor battery life with 4G?
You're not required to have data connection on all the time. A toggle switch widget can fix the problem. Just turns it on when needed. But yeah I do agree that 4g and 3g will drain the battery.

I already keep my Xoom on airplane mode to disable all radios that I don't specifically activate. Seems to help with battery life. I downloaded some toggle Widgets to shortcut all the steps.

That is not really a solution. Currently with my Xoom, I can be on Wifi at home and when I am out, 3G kicks in. I do not want to toggle a widget when I need data (which is always) as I am sure most other people will not want to do. My battery life is totally acceptable currently with 3G and no toggling on/off. So will the 4G upgrade cause the battery life to be cut in half or worse?

Just debating here but why do you think that? Why would Thunderbolt have a 4-5 hour battery life using 4G? You think that poor life is not 4G LTE related? And they have the luxury of swapping batteries which we cannot do with the Xoom.
I don't know how closely it is to sprint's 4g, but enabling 4g on my evo is a battery killer too. the good thing is that you can toggle 4g off and run in 3G mode. no need to disable data completely

I can also guarantee you that 4g will have a pretty noticeable impact on battery life. And to be perfectly honest with you, the HTC Thunderbolt (stock), even with 4g turned off, still has absolutely horrible battery life.

Your response is very defensive and that is not the purpose of my questions. I am looking for meaningful conversation regarding the possibity that a 4g upgrade will significanty reduce battery life on the Xoom. All speculation but something to talk about.
So what I can gather is more or less around what everyone says. Get your 4g upgrade but don't turn it on and stick to 3g unless you feel you need the speed bump. So nothing will change except you know you have your turbo button-widget (yes old school) available.
That is unless it will be stuck on 4g at all times but looks like that is a feature that is toggled by today's hardware not permanent yet due to battery capacities.

I am not one to complain without reason but I certainly hope this is not the case.
MY plan is to remove the dummy card right before shipping it out so I can put it back if I am unhappy with the battery life.
In theory, 4g should use less battery, not more. 3g chipset firmware is highly optimized, though, due to the technology having been around for a while.
It may be a few firmware revisions to hit minimum use for 4g, but it shouldn't use dramatically more than 3g.
The answer for this thread is simple. Yes 4G will use more battery power, that's the short end of the stick. If you live in a 4G area and don't need the speed boost and would rather save battery there will be a way to disable 4G and use 3G just like with the thunderbolt or evo
Sent from my Evo using Tapatalk
It isn't speculation. The evo has a long track record with 4g of a very similar type. 4g will be a battery hog. But I never use it on my evo unless I'm tethered or streaming. Otherwise I find 3g more than enough for most tasks. I will send my xoom in for the upgrade. But I don't activate it. I tether it to my evo. But yes it will be a battery hog. Whenever you use cutting edge technology they tends to develop the speed and reliability first and worry about power consumption last.
I work for Verizon and honestly rarely hear many complaints about the battery life on the Thunderbolt. Many of my customers get awesome battery life and we have 4g in my area. The LTE radio does consume more battery than 3g especially if you are downloading a large file or something. Another thing to consider is the Thunderbolt is like a big brother to the Incredible and that phone had HORRIBLE battery life. The Thunderbolt has a much larger screen, 4g, and does not have a very large battery. I don't see 4g having a huge impact for most people but for those that feel it helps there will always be a toggle widget or “turbo button” like someone said earlier. I will definitely be sending mine in right away...

Sorry but you either live in a nice vacuum or a bubble or a cocoon because EVERYONE I know with this phone (friends, foes and customers too) loves it to death but hates the battery life with 4g on, and by default there's no way to turn off 4g when not needed.
Had to root for some friends and show them the 4g LTE off widget that came out the other day. At least that helps.
As for the Xoom, even if you might not want to use 4g or sign up, still send it in to be done. Definitely will help with resale value down the road.
my friend has the thunderbolt and the battery sucks, and he isn't in a 4g area. Mr verizon rep is on a feel good drug, or something.

It's going to drain more then the cdma radio does, at least until the technology and the software support behind it is more mature. But that is to be expected with bleeding technology.
Also remember that part of the battery issues on the TB comes from the fact that people use it alot more then previous phones. Streaming data is alot more power intensive then just the comparable occasional usage their previous device saw. I have a TB and if I use the snot out of it then yeah I can kill the battery in a couple of hours. However if I am busy and use it like I used my D2 or DX then I can get through the day without having to recharge.
Also you can turn just the LTE radio off when you are not using it if you are that concerned

Well, I'm using ARHD 5.1.3 (based on the official HTC's GB ROM) with radio 12.54.60.25_26.09.04.11_M2 and can say that battery consumtion is siginificantly better than with the Froyo. It's normal when you have less consumption from the phone as a whole to have a higher percentage on the parts that require the same amount of energy. In fact you can optimize the radio software only to a certain amount - it still has to emmit energy as specified by the standards (GSM, UMTS, WiFi) and it still has the same losses in the receivers' amplifiers.
Ok, you are right, but if i compare the battery drain in this rom, i can say that is faster then stock froyo 2.2.1 imho...
I'm so happy someone else noticed it too! I'm having bad battery issues with this update. Took it from charger this morning and currently having 42%. I've done nothing fancy, installed few programs and browsed web. The percentage is going down like crazy
Not a lot of good to you, but I recently switched to LeeDroid's custom Kernel, the difference is night and day. Worth a look.
i see a problem too with my battery after update. i dont know what is the cause. if u find it pls tell here.thk
my radio part also consume much battery, i am ready to flash other radio and see the results.

completely agree with this. just amazing!
I noticed something strange with the signal levels when using GSM/WCDMA Auto-mode. While on 3G it only had like 1 bar and went straight to GPRS, then suddenly lost GPRS-signal to 0 bars and phone changed it to full 3G mode. It bounced like crazy. I forced it to GSM-mode and surprise, my battery life tripled.
I made a hard reset last night and let my battery die two times, lets see how it goes.

Yes you will get much better battery life as the constant trying to locate best signal in WCDMA preferred mode is a big battery drain. Downside is you reduce data speeds.
I wasn't sure if your surprise was genuine or in mock obviousness so have tried to word this carefully.

While on 3G it only had like 1 bar and went straight to GPRS, then suddenly lost GPRS-signal to 0 bars and phone changed it to full 3G mode. It bounced like crazy. I forced it to GSM-mode and surprise, my battery life tripled.
I made a hard reset last night and let my battery die two times, lets see how it goes.

the reason while in gsm mode you had a longer lasting battery is because 2G (GSM/GPRS/EDGE) Takes a lot less power than umts/hspa/hspa+ to function; this is regardless of what device from whichever vendor/manufacturer you're using.
if you're still having issues, use the fast wipe rom to completely wipe your phone, then run the RUU (root it with gingerbreak)

Yes you will get much better battery life as the constant trying to locate best signal in WCDMA preferred mode is a big battery drain. Downside is you reduce data speeds.
I wasn't sure if your surprise was genuine or in mock obviousness so have tried to word this carefully.

It was genuine cos I didn't have same amount of battery drain with Froyo. I always use it in Auto-mode, and with Gingerbread it's awful. I should have mention this in my post, sorry. But the point is, the signal levels went crazy and battery went down. Froyo was almost perfect what comes to this. My battery last 9 hours yesterday, where Froyo 1½ days.
Maybe I should navigate myself to the dev-section and see other solutions.
For some alien reason after upgrading to 2.3.3 , my battery is doubled, if not tripled. Maybe im just lucky that the new radio comes with the update is more suitable with my carrier in my country. I'm now on 3G, autosync , 23 hours after charge and still at 53% , medium use with calling, sms , taking photos and capturing some videos. Before the update my battery dies after like 5-6 hours with 3G and auto sync on. I'm a happy man right now
Ehi guys do you made a factory reset after ota?
I cant see better battery life after two days....

Update to my issue. Seems that hard reset did the magic. I now have 81% of battery, took this off the charger 9 oclock this morning. It's still on Auto-mode like it should be. Maybe it was a cell tower fault or a battery calibration problem.

also having problems after the update: the situation is this - if I keep wifi on and do not touch the phone, after ~8 hours (during night) I have only 66% battery left and battery use stats says that "Dialer" ate most of the battery. Did not notice this before in batt stats
I did a factory reset on my dhd after ota and also format the sd card, because i had always "Telephone" (dialer) voice on battery stats with high % of usage.
Btw, when my dhd was inactive on desk for 5 6 hours, with froyo 2.2.1 (1.72) the voices in battery stats were phone inactive, standy by ecc ecc, now before the format, the first voice was always "Telephone".
Now i wait for next recharge.
some one tell me!
i had on 2.2 froyo a AURO navigation software, now it does not work!! im so angry now!!!
recommend me other apps tha i can use? maps,navigator?

Hi,
See http://forum.xda-developers.com/showthread.php?t=863327&page=53
in my post #523 for a apk file to download. Notice: do not manually update the app in the Android market after you installed the attached file, then you will end up with the same problem.
Just follow the instructions in my post. If you have questions contact me.
just FYI qosmgr is chewing up your battery, if you are rooted and have root explorer (or equivalent) go into system/bin and look for qosmgr and rename it to qosmgr.bak...and if you want to to turn off mpdecision you can look for that process too.
I notice it helps with battery when phone is idle and nothing breaks yet on my end.
Battery seemed fine no drain get a days use no problem. What is that gosmgr?

depend on your usage, if you are on HSPA+ or 4G your battery will eat up more noticeable. QOSMGR is a quality of service manager, I believe it manage your network speed base on certain applications. renaming it to .bak has help me putting the phone into deep sleep a little bit quicker.

not true. whichever mode gives you the fastest download, and the quality of that connection is good, is usually the most battery friendly. as soon as i got lte in my area, i started using it. speeds were so fast that i started using only lte, even wifi i stopped using. using lte, i notice that i get over an hour more screen on time than using hspa+ or edge. edge gives me the worst battery life. this is both my nexus 4 and nexus 5.
imagine this, download a file 20mb in size. via lte it takes seconds, via 3G it minutes, via edge(2g) it takes an hour. via lte its very fast, so the phones arent wasting time and battery downloading it constantly. because of this, battery on lte will end up much better. plus, on top of that, any of the newer phones that have lte are now using a more efficient lte radio. on my nexus 5, i average 5-6.5 hours screen on time. same cpu, but thats a smaller battery than the g2.

That partially true. When you are on LTE, sometime you are connecting to multiple towers therefore using more power. With WiFi you will only using one WiFi module therefore not taking up as much. Typically when you are connecting to WiFi you are using alot less than network connextion this has been true since the beginning of smartphone.
Qosmgr its Linux program to manage CPU governor. The qosmgr program takes as a parameter an xml file with the configuration of governor.
That xml file is in /system/etc/qosmgr_rules.xml.
so its not recommended then?

I'm curious about this as well. I've read on multiple forums for various phone models that adding .bak to qosmgr (as well as to gsiff_daemon) helps improve battery life if you're seeing Android System use up a lot of battery.
I don't know if you are referri g to just stock rooted lg roms or customs. I don't have that in system bin and running vanir. One thing I notice chewing on batt is google play services… specifically gcm. Until now I didn't know what it meant but it is google cloud messaging. I'm wondering if I can use android tuner to disable it and if its ok to do so? Anyone know?

There are a decent amounts of gcm service checkboxes. Just not sure if/ what it will mess with if unchecked.

are you sure its not quality of service in 802.11e
regardless of what it is, I have not missed it, and it does help with my battery.
