Dramatic Battery life improvement - Optimus 7 General

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.

Hi, I have an LG Optimus L7 P705g. My battery life is really good ever since I turn the Batter Power Saver on.

Theory as to why there is such a difference in some people's battery life times

I live in Idaho. Sprint advertises that they have 'mammoth coverage' around here, but they're wrong. They don't. Well, they have coverage (except for my house and office) and the 3G/4G speeds are usually complete **** unless you're within sight of a tower.
Data from the towers out in Caldwell haven't worked for over 2 months and Sprint claims that they're working just fine and have recently been updated - apparently they updated to dial-up. I really wonder how they're even selling phones over there right now.
Idaho = Battery life is usually 5 to 10 hours with normal usage.
2 weekends ago I was in Omaha and used my evo a little bit less than normal, but I could get through the whole day and still have 50%+ battery life left. The 3G speeds were also 2x better, as well as service in general.
I think it depends on where you're located and if sprint has maintained/updated their towers. I also think that most of the towers in Nampa/Caldwell (20 mi. out of Boise) are older nextel towers, which are probably complete ****/half working.
Just my theory.
Sounds plausible, but I have no idea scientifically speaking. I could guess but I don't think it would be productive.
My honest suggestion? Post this over at the dslreports.com forums; there were some really knowledgeable people lurking there.

I agree. In addition to rogue apps/processes, it seems that weak network is #2 on my list of things to check when my batt life is draining too much.
This isn't really a theory, it is fact. If you have bad coverage you can basically watch your battery drain. I could drain mine dead overnight by leaving my phone unplugged and in the basement.. I had 1 bar of roaming service. I now hqve an airave and battery life drains much less overnight.

ive had my batter die in 3 hours because of no service. I watched my battery go from 70% to 30% in 1 hour because of no signal. Since I'm not running CM6 the roam control app has been well worth the couple of bucks. No more missed calls and far less battery drain when im in low signal areas.
Poor 3G low signal is the biggest battery problem for Android!
Android (not the Evo but the entire OS) has a very poor system for dealing with Low Signal for 3G and it does NOT automatically switch over to 2G when it's supposed to which CAN and DOES result in greatly increased battery life.
Other phone OS's do this or are supposed to do this but for some reason Google has just not implemented a good system for dealing with this COMMON issue.
I use a program called JuiceDefender (Paid version is best but the free version will prove to you how useful it is) and it is literally the best app I run on my Evo. Overnight I went from my phone dying by 4pm when working at a location with low signal to having it last multiple days in some cases depending on my usage.
Do yourselves a favor, Get this application and if you have your phone rooted you get many extra features out of the full version. Can't speak highly enough of this application.

I agree with that and know that when you have 0/1/2 bars it really drains your battery life, however, I get the same battery life if I'm at home all day using it (0/1/2 bars), or if I'm at college and have 5 bars all day and I'm not using it quite as much.
I have fresh 3.3 with the htc kernel 53 fps (and all the latest radios/pri/prl/ect.) and have seen much improved battery life, but it's still the exact same.
I also have an airave at the office (which is out in Caldwell where the data doesn't even work) for the other two people on my plan, and while they have seen slightly less battery drain since we got the airave (for free), it's not a mind-blowing difference, other than the data actually works. They're also running the 2.1 stock, but rooted with unrevoked.
I guess I'm wondering if staying connected to a tower with older tech/Nextel uses more power than if it's connected to a sprint tower.

There's no way your Evo is working off of any Nextel towers. Those are IDEN and your Evo is CDMA...not happening. It's been known for years now that if you have poor/no signal, your battery will drain rapidly as the device will constantly search for a better signal.

Good to know - How do people get Sprint Phones to work on Boost mobile then? Boost is using nextel towers, or that's what I've read several times.

You're half right. Boost does use nextel towers--For iDen phones. They do use the Sprint network for CDMA phones. Basically boost carries both CDMA and iDen phones.
As for how people get Sprint phones to work with Boost(CDMA)... Hm... Let's just say they do something shady and possibly illegal...They clone ESNs.

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...

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.

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

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.
inverted apps can by the way help too, avoid white and light colours as background

[Q] Anyone use got poor Battery Life ? and cell handover ?

Hi,
Had it a week now, and the battery life is awful compared to my prior Note 2. The old phone could get through the day, no problems, but this one is flat by 6pm.
I suspect its to do with the Knox process using 10% of the processor (according to usage timelines pro), even though ive not got Knox enabled.
Also it seems to struggle to reconnect to the 3g network (three UK) after losing signal. I have to put it into airplane mode, and off again for it to re-connect to the network.
Hoping both these can be fixed with a software update, but has anyone else found these issues, especially people coming from a note 2
thanks
George
On a poor signal mine is the same, my note 2 has a signal, when my note 3 doesn't. Also battery seems better on my note 2, on day 5 will see how a few more cycles of charge pan out.

I blame Exynos. The US and JPN versions will be much better.
Just turn off all the useless gimmicks such as air gesture and smart xx features and give it a few days before judging. I'm on fifth day with the phone and its temperature and battery life is better than it was on first day.
To give you an idea, that's my battery usage for today and I'm still at 43%. Didn't even start at 100% but 92%. Though I've been on wifi all day with good signal, not on data connection, so that helped with low battery consumption.

Samsung has the worst antennas anyway. where i am living i had 0 to 1 bar at my note 2. with note 3 it improved a little bit. it displays the same amount of bars but at least i can make phone calls with no problems.
At the same area i testet the new Xperia z1 and it has almost all the time 3 and more bars...what the hell samsung...not everybody is living in an signal oversaturated city....
After 5 days, battery life is impressive and improving (i think)

San Francisco doesn't have a saturation of signal?
Same thing again and again.
Buy a top notch mobile and turn off all features that make it top of the line to make the battery last one day.
Really poor battery life on mine.

I think it's a cell handover problem
I'm not sure the antenna itself is weak...I've pulled over 10 megs on 3g in a two bar situation. However it seems over keen to switch cells . I have a tool that logs which cell you are on and even when I'm stationary it keeps swapping cells
Also the number of bars on different brands cannot be meaningfully compared since some companies stretch the truth about signal strength by not having a linear scale *cough apple
Looks like the poor handover was the sim card... went into three store and they said it probably was .
I was very sceptical since it worked fine on my note 2 but it does seem to have fixed it

My battery life is amazing compared to my note 2. I love it

Mines got better too
tbh its got better after a week of cycling.
Its still annoying as anything that knox is munching 7-15% of cpu power constantly and I dont even use it ... however its not as bad as it seems, since it seems its the CPU idling at 300MHz so in fact its less than a 3rd of the apparent figure...

You may try to
- turn Google Now! off entirely, voice search and answers still work just not the cards or some app controls (but there's S-voice for that)
- switch searching for wifi networks off
- I do not recommend turning wifi off during deep sleep, it causes more wakes and drainage on my Nex4
- use the S alternatives of as many Google apps as possible
- look around Maps to see if some sort of location sharing is ticked in, allow the only apps to access location data that you really need
- look around Know security, maybe it is part of the drainage
- optionally: try out AppOps to manage individual permissons per apps, I don't know if this works with the Note 3 though
