Hello all
As the title suggests, fhis setting will improve battery life, but is usefull for USA users only. I decided to put this in a new thread to make it easier to find, I have been going nuts over battery life. As you can tell from my name, I am an athena owner who just got my HD2 about a week ago - but got better battery life out of that huge phone than I do with the HD2. I started reading post after post re battery problems, some got good life, others bad. One who reported good life had it in airplane mode and I realized that the data bands on the phone are useless stateside - we can only use EDGE over GSM. So I made the following setting changes...
Go to comm manager
Tap on phone (NOT ON/OFF SWITCH)
Go to Band at bottom
Change top from Auto to GSM
Change bottom from Auto to (1900/850) (CONFIRM YOUR CARRIER FRQUENCIES!!!)
This stops the phone from endlessly searching for HSPDA/3G on 2100/900 frequency - this eats battery like crazy. Without making any other mod, my battery now gives me an honest days work. Ex. I took the phone off charger at 7:00 am at 100%, its now 10:30 pm and I have 25% remaing a full days use, I even posted this from my device.
For those with USA ATT or T-Mo, let me know how it works for you. My phone is straight out of the box, no mods or reg tweaks and this single change almost doubled batt life.
Enjoy!
Omg if this works i'll kiss you. I never bothered to click on that band setting, so I didn't even know those options were in there. The only thing I thought I could disable was in Advanced Network settings.
Good thinking that man!
it give you better battery life but well cost you on webb browsing slow gprs no 3g speed i hope it helps
We are in the US so we can't use 3G on our HD2's. Edge is actually pretty fast on this device, a lot faster than my iPhone 3GS is on edge.
Admittedly my day has only been a Saturday, but the battery (at 7.20pm) is still showing 70% and I only changed the 'Auto' at the top to GSM...didn't do the rest! Cool!
Full day at work...35% battery left! Looking good!
Thanks!
This worked great I did not even have to switch to my Xperia X1 today. I think I will try this on my sony to see if I can push it to a two day of battery.
9.10pm and it's still at 29%.
Thanks!
I don't know about battery life yet but in the case of bad reception it actually downloads data much better.
When trying to download data it used to constantly fail, but now it works immediately. Apparently otherwise it tries to download in 3g and fails. When there is good reception it knows what to choose but not in the case of bad reception.
I still can't get over that the US doesn't have proper 3G coverage though... I'm in Aus and our 3G coverage is quite good. Don't have to worry about it switching to GSM
I know this thread is centered around battery life but does anyone here have the HD2 and using it on at&t? If so, do you have the ability to enter at&t settings to get MMS messages in the new HTC messaging app in the HD2?

Isn't the problem that the US use different frequencies in their 3G network than most other countries, and the HD2 that retails now does not support it?
It used to be so with the Diamond/touch pro if I recall correctly.
Got my LTE upgrade done on my Xoom and now the battery is a joke. I went into settings and disabled the LTE connection, so that now 3g is only used. I also turn wifi on when at home. Currently my Xoom is draining 4ish% per hour while in standby. That means this damn thing won't last a day just sitting there, locked, with no screen on. In Honeycomb 3.0 and 3.1 I could get a days of use with 4-5 hours of screen on time and about 22-26 hours of total unplugged time. Now, under 3.2.2 my battery is totally dead after 18 hours of unplugged time with around 1-1.5 hours of screen use. This is virtually unuseable for taking notes in graduate school after work, when being close to an outlet is impossible.
Any ideas as to what's going on? Tried using Watch Dog and System Panel to see if any apps were going nuts with random CPU usage or RAM usage and everything seems to be in-check in terms of system resource usage. Considering I have 4g totally turned off and wifi enabled when I'm in range of wifi (most of the day) I don't have a clue where this power drain is coming from. Any assistance is highly appreciated given how much I rely on my Xoom for day-to-day use. 3.2.2 seems to have killed it for me.
Please help! Will try any suggestions.
Thanks.

Have you tried disabling mobile data entirely? When I'm in wifi, I disable the cellular connection but haven't performed any in-depth trials on battery life.
"Settings" > "Wireless & networks" > "Mobile networks" > deselect "Data enabled"
Its not just you, mine is the same way it sucks big time. There really isn't anything that I've found to fix it.
I loved how I used to be able more than a day out of a charge...
Anybody have any ideas? Maybe undervolt kernel???

I haven't but this isn't feasable. I use mobile internet for everything and even take notes and such on Google docs. Even though I'm near wifi for most of a given day, I shouldn't be bothered by manually turning mobile data on and off just to have power- mobile data should be mostly killed when wifi is active. That's how this Xoom worked before. A tablet without internet is nothing more than a paperweight to me. 2 classmates with LTE upgraded Xooms are having identical problems. No fixes found yet. Any other suggestions? This battery life is really, REALLY bad.
Tried going a factory reset and battery life is the same, horrid short, running nothing but stock apps.
Any other suggestions?

How long ago did you receive it? The degraded battery seems to have started shortly after the first initial charge after the LTE install.

Same problem here, but I have the mobile network completely turned off and it still does this! Even with the switch to CDMA only!
I will keep reading this thread (only read the about half the posts before posting) so hopefully a solution will show up. But you're not alone in the horrible battery life post LTE upgrade!
I've had my Xoom back since last Wed.
No higher battery drain than previously.
I'm on wifi 90% of the time in home and office.
Yesterday I was all over north San Diego county using 4g. Got home with 60% charge which is about the same as for a prior trip with 3g.
Put your xoom back the way it was. The new hardware sucks the battery a little more. Buy a thunderbolt and then say the xoom battery life sucks. Never charged it during the day before the upgrade. Oh well, that's the price if 4g.

Download Auto Airplane Mode by DON from the market. It will help BIG TIME!! It does just what the title states, it puts the Xoom into airplane mode automatically as soon as the screen goes off. When you turn the screen back it, the data comes right back in 3 -4 seconds and you're good to go!
Also, you don't have to uncheck any settings or turn 4G off.
Update: Mobile data completely turned off, on wifi only with Xoom sitting about 4 feet from router all morning, so wifi signal was strong. This is the first time I've used the device today. Unplugged at 330am my time, its now 130pm. Device battery is at 60%. 10 hours and 40% of battery gone. That's with mobile data 100% disabled, wifi only- can't even get the Xoom to standby for a full day now. At this current drain rate, it would go from 100% to 0% in one day with no mobile data usage, no screen on time and no usage other than syncing Gmail every 2 hours.
Brother who commented above: Thunderbolt will standby for a full day with no screen on time on wifi only and it has under 1/3 the Xooms battery capacity. I should know- my wife has one and it now outlasts my Xoom. That should not be the case.
From my understanding the Xoom has two 3225ish batteries set up in a sequence. My battery life actually seems to be about half of what it was before. Is it possible that one of the two was disconnected during the LTE radio installation and not properly reconnected? Wasn't sure of the details of how the batteries were set up, but if the Xoom could function with the second battery not working, seems like that would precisely half battery life. Anyone familiar with exactly what had to be done internally to upgrade the radio? Looking at the ifixit teardown of the Xoom, the batteries cover the whole backside- looks impossible to do any internal work on this thing without removing them. Any thoughts?
Cheers,
Landon

Same here. Can't get a full day out of it. Hope a fix will be comming up.
Thunderbolt got the he-man battery and modded my otter box to fit. The xoom battery has entered the battery hog realm after the lte radio. As far as I can tell the radio is cdma/lte together. And it uses power even if wifi is on and data off. It's what I would call big brother watcher. Even if your not connected the radio is txing and rxing something. You know it's lojacked!

Interestingly enough, removing the LTE SIM card and using wifi only made no improvement to battery life. I'm assuming the new radio is running at 100% all the time without throttling down, even if absolutely no connection exists or there is a string of faulty battery reinstalls in which only one battery is providing power. That might explain why some people seem to have greater battery issues than others.

im glad im not the only one with this problem! its pathetic! im taking my charging cable from my dock with me to work so ill have at least some battery life when i take the train home in the evenings
i to am glad that I'm not alone with this either. I use to charge mine every 4 days with no wifi on and almost no use. Now I get about a day with no use. I mainly use it for web searching and dungeon defenders when I'm home. Horrid battery life for doing nothing. Luckly I mainly only use it at home and am almost always on the dock I got from motor from the upgrade. I use about 4% an hour also with nothing on. Mine is completely stock with no root.
Yahoo mine is stock with absolutely no root or other mods. I guess they knew about the pissy battery life and that's why they gave a free dock. Lol. Still trying to find exactly what's killing the battery. LTE does drain a lot of juice but as I've stated before my wife has a Thunderbolt and per mW of battery power, the thunderbolt is more efficient and that's not saying much. It can standby for over a day with no use fine and it has roughly a little less than 1/3 the Xoom battery capacity. Something isn't right. Its not supposed to be this bad. Anyone filed a complaint/tech request with moto/Verizon? I think its something that we should all do and report what they say here. I have a feeling more and more people are gonna have this issue if they do the upgrade. Maybe if enough of us make some noise, something will be done.

Maybe it's not the radio.
3.2.2 may have some kind of interaction with something you guys were running that's causing wake locks to get stuck
Did you look at Settings:About Tablet: Battery Use ?
(tap on the histogram at the top for another, see if the time spent awake is solid or different from screen on)
I tested this on mine, with the mobile data disabled and lost about 1% battery every hour, this is on par with the performance I had pre-upgrade.
Rooted, stock kernel
I realize it does not help you but you might look somewhere other than the wireless radio for the problem. I unplugged my upgraded Xoom yesterday morning around 8:30 AM. It is now 8:20 AM and my battery is at 66%. I was on 4G for about 2-3 hours yesterday, the rest of the time on wifi. I check and respond to my mail on the Xoom so it saw some use yesterday, though not as much as I normally do.
I had been suffering terrible battery life of late espically with Blue tooth enabled, however just recently 2 events occurred that coincided with a dramatic improvement
1. I switched from T-Mobile (UK) to GiffGaff
2. Partly as a result of that switch (and me being a little thick and forgetting to apply the ADN settings in order to get internet over 3g working after the switch over) I carried out a factory reset via the Settings -> About Phone menu options
Since I have done this my battery life has gone from less than a day to at least 2 days and possibly into 3 and that is with Blue tooth switched on
I am not sure that these 2 events caused it but something has happened all of a sudden to make such an improvement
fyi:
O/S 7.10.8107.79
F ver 1.1.7.10
R Ver 1.1.7.10
it's the factory reset. helps for some users. i'm not ready to reset and reinstall though. got too many maps downloaded on the phone. so i'll stick to my spare charger...
I tried resetting to check if it worked for me. And it didnt. The remaining battery estimate was reset and hence it estimated more battery life than the real experience. After a week or so the letter was back "to normal": 1 day and a few hours... my firmware is 1.0.16.10 though.

Cellphone's battery usually lasts longer when in a carrier with stronger signal. Maybe the signal of your new carrier is stronger than the old one where you stay for the most part of your day.

This is definately true, GiffGaff (O2) has a much stronger signal where I live / work , I couldn't get a signal in our office down south, but now I get 5 bars!
So far I have gone 2 days and 4 hours with our charging and battery life is at 39%

True... a phone that is not receiving a strong signal will continually seek a better connection... thus eating up battery.
Setting to a lower band for voice & text will greatly increase battery life.

Battery
Hi, I have an LG Optimus L7 P705g. My battery life is really good ever since I turn the Batter Power Saver on.
Hi everybody,
i just came back from upgrading my contract and got a brand new Motorola RAZR HD XT925. Just got it and I am getting used to it. The bad part is that if you live in the US you cannot get one without a contract.
First impressions: Feels nice, I love the proportions, nice screen, incredibly light and sexy.
BAD: Hate the Telcel bloatware and the fact that I cannot use the rings widget on ADW Launcher. Wanted to use that one to at least hide it...
On some good news, the bootloader is unlockable.
I have it unlocked, with the SFR 4.0.4 ROM and JB OTA update. Everything is running really great. Got rid of the bloatware. And the best part is that battery lasts for two days with heavy use! I love this phone.
i got too the razr hd from telcel, im from mexico, but my battery doesnt last a lot, i unplugged the phone by 7am and by 10 am o 11 am i have 70% with normal usage i mean at that time im at work so i cannot use the phone that much, do you think it could a battery problem and go to see for a replacement? i have one week today with it and it doesnt last more than 7 or 8 hours with normal usage :crying:

Weird, the first day I got it i went for 12 h 50 m on battery without charging once and still had 30%. I made around 1h 20m of calls and 1h 40m of display time, wifi and gps turned on all the time.
I have battery widget? reborn! and it estimates that a fully charged battery lasts 18 hours.
So if I were you, I'd wait two more days. If with similar usage to me, you get much less battery life then exchange it. Maybe your version of "normal usage" is actually quite heavy :silly:
IF you do have similar usage as me and are on stock, perhaps your problem is that you always have LTE signal and that drains battery quite fast. If so, you could set a smart action so that when you are on work location, to get to turn off mobile data, bluetooth. I would preferably set it up so that when the phone is not moving, it does that in case you always put your phone on your desk/drawer or something.
Saludos,
Gustavo
EDIT: another option is to go to settings:: wireless&networks more... :: mobile data :: select network and put to select only 3G/2G or even only 2G

IMEI, yes. But I easily recovered searching on Internet.
LTE, I don't know. I guess so. I'm using CM10 now and I only can get HSDPA Plus speeds. I don't know for sure because I didn't connect to the network to notice if Telcel's ROM have the letters LTE on the status bar.
Hope this helps.

Hi Royalfox, Guadalajara too, if my HD is rooted, can be upgraded OTA or i have to unroot?? THX
I'm using a sprint galaxy s4 on ting, and while I'm 'okay enough' with the phone to not want to futz with upgrading, one thing that's made me reconsider is that I notice really fast (like 30% over an hour sitting in my pocket) battery drain when I'm in an area with low cellular signal. Particularly there's a coffee shop back section I sit at where this happens. My battery is also years old, but it's worked okay at home in standby.
Any idea if there's a baseband version I can switch to or things to observe to see if this is fixable? Using stock 5.0.1 rom with L720VPUGPI2 baseband.
Wont let me comment
Have you heard anything on this? My brother has same issue and also wants to root but i cant find anything on this build #
