Radio post last OTA 2.3.3 power consumption

Do you think the radio part in last OTA 2.3.3 consumes more battery?
I see the battery information consumption much higher in "Phone".
Confirms it for me?
PS. this morning, after 5 hours and 35 minutes battery down to 90%

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.

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)

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?

Post LTE Upgrade Xoom Battery is Horrid. Any fixes?

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?

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!
Sent from my ADR6400L using xda premium

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.

Dramatic Battery life improvement

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.

3G Drain on Jelly Bean

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.
Sent from my GT-I9000 using Tapatalk 2

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

Lollipop update giving HORRIBLE battery life

Anyone else had this problem?
I installed the stock 5.0 update (G900FXXU1BNL9) on my SM-G900F and now the battery life is terrible. I'm lucky if I can get it to last until the end of the day. Today, it's dropped to 50% within 5 hours. Before the lollipop update (again, was on whatever the latest stock version was), my battery life was superb, lasting almost two days!
Anyone know how to resolve this?

battery life
I've had my phone off the charger for less than one hour and I'm already down to 90%. There's definitely something wrong because stock lollipop unroot was giving me much better battery life and performance.

Mine lasts about a day and tbh for a device with the specs of a low end PC with a HD display and constant internet connection thats about what id expect

well mine lasts a day now and it did then. so either you need to factory wipe, or you need to look at apps you've installed thats not quite optimised for lollipop

Yup, factory reset solves battery drain after LP update, I was up to day 3 without charging this morning with still 18% battery left, but had to charge up as I was going out, reckon it would have lasted the rest of the day though

Factory reset will lose root more than likely, almost certainly

It happened with me but after 2 days everything settled and battery lasts at least 12 hours but still less than kitkat.

I installed the update to lollipop..... After that indeed a horrible battery life. So I installed lollipop again using kies software......

Had same experience wipe and reload greatly helped. Supposed to be addressed in 5.1.

To add yet another subjective and anecdotal experience with the new S5 Lollipop update (on Verizon, in my case), I was seeing constant Wi-Fi disconnects (~5/minute) AND battery-life that went from ~15 hours to < 5 hours, until I turned off the "Smart Network Switch". Seems all the network switching was killing the battery as well. Did a FDR and it made no difference. As long as that feature is turned on, my Wi-Fi drops constantly and the phone heats up and the battery dies in a few hours, even without use.
Would be nice to know what I'm missing now that my phone is, apparently, using the Dumb Network Switch instead.

All you're missing now the phone is using the dumb network switch, is bad battery life, constant wifi disconnects, and headaches
I turned it off a while ago, and so have many more people I read about each day - it's supposed to keep you connected to the strongest signal, but in reality, it does the opposite, plus most people only have 1 wifi connection, so it's not necessary to smart switch - and even without it enabled, it will still connect to Data when it goes out of range of WiFi, so that switch is completely pointless to start with

Yeah, I kind of figured that. Sadly, I do have two wireless-access-points in my home to handle range-issues. I had not considered that this "feature" would have a bearing on the switching between them. I did test with one of them turned off, so I could eliminate that as a possible cause before I knew about this broken functionality, and it didn't matter of course.
Does it not seem a bit odd that testing didn't uncover that a Lollipop Galaxy S5, with Smart Network turned on, would kill the battery and render the Wi-Fi inoperable?
Oh well.

You could set up your two APs with the same SSID / Encryption key and have the phone switch seamlessly between them without smart network switch enabled
Some info on how to achieve this here

But yea, it seems that there are quite a few overlooked bugs with lollipop, 5.0.2 and 5.1 apparently address a lot of them, but when we get that update is anyones guess

Anyone else had this problem?
I installed the stock 5.0 update (G900FXXU1BNL9) on my SM-G900F and now the battery life is terrible. I'm lucky if I can get it to last until the end of the day. Today, it's dropped to 50% within 5 hours. Before the lollipop update (again, was on whatever the latest stock version was), my battery life was superb, lasting almost two days!
Anyone know how to resolve this?

Wrong section, all questions go in Q&A. Not general.

please note that there are some apps are working without permission like google music i think ,

I recommend you to stay in KitKat until Samsung Lollipop 5.1 firmware arrives. At the moment I'm using XtreStoLite ROM with Toiiki kernel and I'm getting am awesome battery life, about 8 hours of screen on, cheers.

My S5 is G900H and I have the same problem. I did not like lollypop
