My friend got a Gnex but..

Hey guys so my friend join my line on verizon on a family plan and he really wanted the nexus he likes it i can tell it , however he asked me today why with minimal usage 11% of battery dies within 2 hours
he is on stock 4.0.2 what can i suggest him to have a better battery life? of course i rooted mine but its his choice and he does not want to.
what i suggested
1) lower brightness when not really using the phone
2) get easy batter saver
3) turn off gps when not needed
4) turn off sync when not needed
5) switch TO CDMA from LTE when "LTE" not needed
what else?

Freeze maps when not using. And make sure you clear apps runing in the background when your not using them. Push the multi task softkey and swipe whatever is open to the side

wait... as in he loses only 11% of battery in 2 hours? That's really solid battery life for an LTE version...
All stock the most you should probably expect is 3 hours screen on time over the entire battery usage.

how to freeze maps?

When you swipe the apps left/right from the multitask, does it actually close them? I haven't checked myself, but heard it doesn't? Anyone care to see?

Yeah it is. Only LTE phones that I can think of, that have a great battery life,
are Verizon's Droid razer maxxx and Att's note (<- from what I've been told).
Overall, your suggestions are on point Pat.

you can disable it when you're stock. go into the app info (drag Maps from app drawer to the "info" icon or go from settings) and uninstall updates then disable it.
Or if you're rooted you can use Titanium Backup to "freeze" applications. It just disables them and you can bring them back later.
Honestly, there's really no need to do this if you use Maps at all. Its a hassle and really doesn't save any battery life unless you have a buggy ROM that keeps it running. Just make sure that you're signed out of latitude etc. and Maps won't be draining battery.
There are so many more things you can do to help battery life than worry about Maps.
OP I'd like if you could clarify what you mean in your first post. If he really only drained 11% in 2 hours that's really good for this device. Most LTE users with normal usage and settings can get about 12-15 hours uptime with 3 hours screen on.
The things you noted in your first post are all good ways to save battery but remember its a trade off! You're going to remove everything that makes your smartphone useful to try and lengthen your battery. I leave auto-sync and background data on, GPS on (it actually only turns on when you use it, btw), and just let it be. I do better on battery life when I stop trying to micromanage my phone.
Apps like Juice Defender etc. really can help in specific situations, but for most people it will hurt or have no effect on battery life, but will severely inconvenience you turning on/off data all the time and changing settings.

well he gave me an estimate (basically he said around 2 hours 11%) hes coming from iPhone 4 so there is huge battery performance 3g vs 4g
anyways he will have to stick with it
on another hand my rooted gnex does pretty good about 14 hours with franco kernel
i was just wondering which kernel governor is the best?
mine is set as FRANCO TURTLE and i have no idea what is the difference between other ones

Root it and flash 4.04 it will give you battery life for a day with moderately heavy usage.

Buy the extended battery.

[Q] Juice Defender messing with Data connection

So i installed Juice Defender and immediately noticed a sizable boost in Battery life... BUT... my Data connection was more flaky then it was at stock
So one day when it is critcal mass I uninstall it real quick so I can have the data connection I needed so badly at that moment. Well... after that the battery performance has been MUCH worse than it ever was before.
Anybody deal with this yet? Anybody know how to set the program not to mess with the data... or how to....????
My rooted GNEX config is in the sig.

I found that is messed up my data connection too but that's the most part if how it works to save your battery by switching to 2g when screen off and 3g while screen on. At least that's how its meant to be. I uninstalled it as 3g would rarely come back on.
Look into other settings to save your battery like screen brightness, auto snyc, GPS, wifi (if your not in a place with it), lock sounds, key press sounds, vibrate on touch, vibrate on key press in keyboard. There's loads of things lime that which really help.
Maybe also look into certain apps being high memory usage in settings menu and look into how many apps you got installed.

This may not be of much help, but I used it for a long time with my tbolt and never had an issue, but no matter what I did with the bionic it would almost never regain data with screen on. So I think it *might* have something to do with the actual hardware. Don't quote me, just my two cents. However, after uninstalling on the bionic I didn't have anymore issues with data than I had before installing.

Oh, and I forgot to mention that juice defender saves battery by killing the data connection. It doesn't save battery any other way.

Same deal here. I just set the app to not mess with Mobile Data by clicking the customize button under profile and going into the new Settings tab that shows up then disabling the Mobile Data option. Still testing...

2x battery
I had trouble with juice defender also so I changed to using 2x battery and I have had much better results.

Toggle the 4G by swiping down and unselecting 4G, wait 10 seconds, then toggle 4G back on. It will come back, everytime for me.

ever since Gingerbread came out, JuiceDefender is not recommended for android OS

Pretty much the only major thing Juice Defender can do to "help" battery drain is turn off your network (or toggle it to 2G only on GSM phones, 3G only on LTE phones) when the screen is off.
It generally wastes more battery frequently toggling it on/off when the screen changes state than it saves by doing so. Not to mention that you can't get background alerts etc. when Juice Defender is toggling your data around.
The only time it ever really saves you anything is if you're not turning your screen on for long periods of time, in that case you could simply manually toggle off your data if you know that will be the case. Juice Defender runs as a process in the bakcground constantly, which effects your battery negatively also.

pretty much what he said. I used JD Ultimate for a month before I gave up on it. I don't notice any decrease in battery life since I did so. Betterbatterystats showed an awfully high number of wakelocks when JD was active. The wifi "Location" feature was nice though.

Like previous posters have said, the problem with JD is that when it toggles you data, it will force your phone into an awake state which drains a bit of battery. I'd like to add that, from personal experience, if you usually have JD toggle your data on more frequently than at 20-30 minute intervals, you might as well turn off JD. The battery saved from turning your data off and the battery wasted putting your phone on an awake state isn't worth it. On the other hand, if you toggle your data less frequently than every 30 minutes, the benefit exceeds the cost and JD actually helps you save battery.
Since I need my data more often than that I have turned off the data connection management. I still leave JD on for the location-based Wi-Fi management though. That's actually useful and saves me having to worry about turning on my Wi-Fi when I get home/to college.

I'm never a fan of any so-called battery saving app.
All they do is turn off your data or turn down the brightness.

I'm a fan of Back button long-press kills app. Then i just check for bg processes of said app and kill them as well.
If i have apps that need background sync, i always make sure either to leave wifi or data on (i know it won't need much, a few KBs maybe) so that apps will have connectivity when they need it, or, if available, sign out of the app (examples: gtalk, latitude). It will cost me more battery if the app keeps trying to find network connectivity and not having it, than the drain of wifi on or data call active.

I disagree. When I used it on my tbolt went from a drain of 40-60 mAh to 20-25 mAh using battery monitor widget polling at 60 sec intervals. And I never missed anything. But I used jd ultimate that allowed data when apps requested it. I also typically got 6 extra hours of use, which meant I could make it though an entire work shift vs. having to recharge after lunch. The only reason I'm not currently using it is because of issue with the bionic data not restarting. That's the reason I think it's an issue with hardware compatibility. Because even if I let the stock Android manage the data connection I still have issues with data restarting on the bionic.

Juice defender did really extend my battery but I found the only part I really used was the WiFi location feature. I started using WiFi unlock at home and got [email protected] to turn off WiFi when I'm away from home then turn it back on when I get home. Yes, I'm that lazy/forgetful.

JuiceDefender was great on Gingerbread and Froyo, but I've noticed that it just seemed to hurt more than help on Honeycomb and ICS. My battery life on my GNex, in my use case, went up when I uninstalled it, as did the data drops I'd been having.
I suspect that as stock power consumption continues to drop with new OSes, JuiceDefender is going to be viewed as a relic of a bygone era.

I will have to say that it has helped my battery but in my work environment I lose signal while my phone is in my pocket plus I can't check my phone for two hrs or more. So I would say in my case it has helped since I would forget to turn data off. I also changed my settings to toggle data every 30 min instead of the default of 15.

I was talking about JD's performance on ICS; on the Galaxy Nexus specifically. JD was great on my old Gingerbread and Froyo phones but with ICS it seems to be obsolete (under the conditions I described in my previous post at least). I don't know if it's just how ICS works or if it's because JD hasn't been optimised properly for ICS but that's how it is right now.

I bought JD Ultimate, and eventually had to uninstall it after I found it was causing too many glitches in ICS. I wasted 4.99, but live and learn I guess.

[Q] Juice Defender: does it work?

Hi, Ive been reading a lot about battery saving apps that I started to get curious as to whether these apps really work.
I installed JD out of curiosity and I have to say that all it doea is disable automatically your phone connections to help you save power. Things that you can actually do manually. Like turning off wifi and mobile network. If im not mistaken you can disable mobile network under your phone's settings.
So my question is, if you can do it manually, what is the point of apps like juice defender? It eats up ram and runs as a background process which in my opinion does more bad than good to your battery unless your the i dont know how to disable connections manually in my phone kind of guy.
Somebody please enlighten me. Thanks.

I have used it for a long times. Since I used Xperia PLAY.
I think this program is good. Yes, if you can manually do it. But the feature I like the most is Screen. It can change CPU ghz according to your screen on / off.
It saves my battery a lot.
Press THANKS if you agree with me.

I am a long time user of jd but these days the only feature i use regularly is to disable data overnight.

- Airplane mode over night
- automatic wireless connection with "location" feature (if near a known wireless network it starts the wireless and connects, if not near it directly starts 3G)
- I do not have to mess with on/off wireless/3G
- automatically syncs every hour, so I have to do nothing but still get my mails
- with rooted phone underclock on screen off
- bluetooth off after 5 mins without connected bluetooth device
etc....
It is NOT for you if you want to have online connection all the time. And it is not for you if you don't mind to do all the things manually it does for you.
And in my opinion only the full version really helps, the free version does not much...
I think it's a great app! :good:

If you just need to auto toggle data, check out 3GBattery too.
https://play.google.com/store/apps/...wyLDEsImNvbS5teXN0aXF1ZS50aHJlZWdiYXR0ZXJ5Il0.

basically, there are 2 main things that drain our devices: 1) 3g/2g and 2) display brightness. I've been using JD since ever, and the difference is awesome with and without. Even the free version is enough to save some batt, in the Agressive mode (connects every 30min).
Besides JD, I am using Greenify. Which needs root to work and does a beautiful job with background apps like Facebook, GMaps etc.

works on both my devices :good:

Personally I think this app is useless.
As OP has said, you can just set up those things manually.
This app just eats RAMs and use your battery up more.

Ways to save battery on a rooted G2/Desire Z?

I have a rooted G2/Desire Z. What are some ways that I could save battery? It seems it takes only a few hours for it to reach 50%. Granted the phone is now >2 years old and the battery is probably aging. I've done all the basics such as screen brightness set to auto, dim after 30 seconds, etc. etc. etc. What more could I do?
Alternatively, are there any apps that can control the phone/cpu to work a certain way to save battery life?
Thanks

Honestly, way number 1 is to get a new battery. Old batteries just start to drain much faster as they get older. Pick up an Evo Design 4G stock battery for a nice boost.
2. Turn brightness off auto and put it as low as you can handle. Keep a brightness slider on your notification bar for those situations you need to turn it up quickly.
3.Turn everything that "syncs" off of push and set it for 1hour+ intervals if possible.
I have had great standby time using the OC daemon that is packaged with the mimicry ROM as well.

There is this trick that helps. On a monthly bases drain the battery and re-charge with the phone on ie also a good Rom an a good radio version like .19 will keep your battery good don't use lots of ram manager apps and bettery saver apps the run backgroung processes that drain your battery fast

^This (regards to #1), and working batteries are rather cheap, the fat one I got (3500mAh) was 9$, but you can easily get a stock replacement of the 1300-1500 range to fit with the default battery cover.
Far as tips, rooted or not:
1) Screen to automatic, or avoid 'full brightness'. Your screen consumes the most of your battery, automatic or lower brightness can improve the life significantly. This is the big one as your screen will typically be 80-90% of your battery life.
2) If you are near wifi often, System Setting -> Wifi -> Advanced (via menu) -> Sleep profile to always on. This will set it so that the wifi connectivity is always on even with the screen off. A connected good wifi connection uses far less battery than your 2G/3G data constantly searching for a good or better data connectivity. Simply turn off wifi completely when not in an area with wifi (or if you're driving around).
3) Avoid unnecessary applications. Don't use twitter? Freeze/Disable the application under manage app or under Titanium Backup (generally it's not good to 'uninstall' an application completely if it came with the rom).
4) SetCPU with profiles is one way to do it, unless your rom comes with a CPU Daemon already (ie: mimicry with virtuous OC Daemon), When setting a "screen off" profile, try not to go below 768mhz for the maximum, as going with 384mhz for example may be too slow for the phone to effectively wake up when a call or notification comes in.
5) You can use an app such as Tasker (not to be confused with task killer). Where you can assign automatic tasks, such as automatically setting Radio to 2G when connected to wifi (some roms like AOKP do this automatically under power control), or other tasks depending on the circumstances.
6) The first time you get a new battery, make sure you leave it on the charger for a good 5-6 hours so that it accurately 'tops off', the phone won't know accurately what's 100% and what's 0% until it has been fully charged (least 6 hours minimum), and fully drained, after which it'll more accurately report your battery % as it's used and will have more accurate usage stats.
7) If you're a T-Mobile subscriber, consider the 26.13.04.19 radio as well as the T-Mobile Wifi calling app, wifi uses less power in the long run than your radio via cell towers. If you'll be in a location that has wifi often you will benefit from this over not using Wifi Calling. (The main downside is you cannot currently send/receive MMS over wifi calling, but Calls and SMS[txt] work fine). Even if you don't use the wifi calling app, the 26.13.04.19 radio provides better battery life over the older one.

Course it helps to clear battery stats before performing this task so that the OS/Battery-Stats records the new maximum and minimum values of the battery. Though you don't need to do it monthly, I would say closer to 6 months would be appropiate if you don't want to make a monthly habit of it.
You mainly only do this on account of battery aging (over time the battery will not hold as much charge as it once did), You normally know if you need to do this task again if it appears to be on 98% or 99% forever never reaching 100%, meaning that the battery is no longer able to hold the juice to provide the former-maximum mV value, re-doing the battery stats simply makes the new maximum marked as 100%.
PS: Strip419, on an off-topic note, I tend not to 'thank' people who ask/beg for it. If your post is worthy of thanks, they'll be clicked on their own accord.

Best rom I've ever used for battery life is EliteMod. That rom did something crazy, cause my phone lasted for days before it need charging, and I use facebook and all that good stuff. It's not as fast as other roms, but battery life is certainly the best on that rom.
Also yea, before with stock battery my phone would last a day at best, and now I have a 1800 battery that makes it last for 2 days easy. So if your phone is at least 2 years old, get a new battery. They're dirt cheap on Ebay or Amazon. The phone comes with a 1300 stock.

simply change for normal use 2G instead of 3G.

A couple of questions--I'm using EliteMod CM7

My Advanced settings don't look quite like yours, alas. (I'm using EliteMod cm7.) The section is entitled "Wi-Fi sleep policy, Specify when to switch from Wi-Fi to mobile data" and the only options are " When screen turns off," "Never when plugged in," and just plain "Never." I assume that the "Never" option, that is, never switch from Wi-Fi to mobile data, is what you mean...that is in any event the default (set by this particular ROM?)
But my problem goes beyond not quite understanding the semantics of "Never" (off?) vs. "Always on." What I continue to find odd is that my highest battery usages, at least according to Battery Monitor Widget, are never the screen at all; rather they are cell standby, Wi-Fi, phone idle and Android System...Display is down at 6% just now, for example (and I've been up for hours, have read the news on the phone, emailed, texted, etc. This is on EliteMod only, btw, I used Flinny's latest build (.94?) for a few days recently, and while battery usage was worse, at least the display was at the top of the list, where it (presumably?) belonged.
I have all the latest and greatest tweaks from the the forums (for cm7 roms, that is) the .19 radio and sd-ext and all ext4 partitions. Am running the generic 3500mah "fat boy" battery...drained and refilled several times, all according to instructions...mine only shows maybe, umm, 2300 or so mah, but that's not the issue for just now...it's why my usage looks so odd, and how to fix it, if need be.
thanks to all,
p-d
oh yeah. I have long used (pre-rooting) Lookout and Pouzerate's Green Power free apps...have now turned them off (well, uninstalled them, in fact) just to see if, indeed, battery helper apps make things worse, running in the background... any thoughts on that topic would be welcome as well.

Moving to Q&A

Best battery saver apps for nexus 4

Hi All,
I would like to invite your suggestions on best battery saving apps that you are using and how much difference does it make. Is it worth paying for apps juice defender ultimate or so http://forum.xda-developers.com/images/icons/advanced/battery_full.png
I am on stock (rooted) 4.2.1 and stock rom.
Thanks!

Best battery saver is your self. These apps don't work any better than you doing the things it does manually. If its using resources which they all do to "save" you battery... Its not really saving you battery.. But in fact using it.
Some tips I suggest:
Turn sync off in everything. Go to data usage hit the menu button and uncheck auto sync data. Also you will want to open apps that have notifications and make sure they aren't syncing either.
Remove maps if you don't use it or disable it at the very least this will keep it from polling your location and wake locking the device.
Keep your running apps to a minimum and force stop any unnecessary apps.
Turn off Google backup services. Sometimes this will be pulling and pushing data wake locking the device and using battery. I've never found it necessary especially since I use TiBu anyways for my apps to restore. It never saves my WiFi password either.

This isn't particularly good advice in my opinion. Are there apps that do use battery power when you don't force close them? Yes, sure, but many don't. And those which do without a good reason.. try to find a replacement.
Force closing apps all the time especially on a device with lots of ram will mean that your device has to restart the app completely if you open it again, which takes time and energy.
edit:
Also, turning off sync doesn't really help that much if you still use your apps often but instead refresh manually with the screen on, I'd expect. Of course everyone can decide for themselves, but one of the reasons I own a smartphone is because it can notify of an incoming email or something without me having to go to gmail.com manually. It all very much depends on what you want from your phone and how much you are willing to compromise. Using an App like Lux for example could also save you some battery depending on how bright you need your screen to be etc. There are so many variables to this.

Best battery saver is to not run crappy battery hogging apps like juice defender.
Turn on auto brightness, check your apps and make sure you are not syncing very often unless you need it. For most apps you can turn off auto sync and probably sync manually. I just turn on auto sync for handful of important apps which I open regularly.

Manually turn down screen brightness, don't leave the Wifi or bluetooth on when you're not connected, make sure apps you install aren't keeping the phone awake. Not much else actually works in the real world.

I get two and a half days from my Nexus 4 battery, I can thank Juice Defender Ultimate for a large part of that.
I could do all the tricks that Juice Defender does manually, but it would be a PITA and I'm sure I'd forget some of those tricks.
Better to pay a few quid, take a little time to set up Juice Defender, then sit back and enjoy your doubled battery life.

the best part of Juice Defender was turning off Wifi when not at home.. if you like this feature, search the playstore for 'Y5 Battery Saver'. It does the same thing, is simple and free..
Note: dont backup and restore it in titanium though. If you rebuild, install from the playstore. I have found it doesn't work right if restored

IMO if all you want is bt/wifi to toggle when you aren't home spend $5 on a few nfc stickers and stick one by your front door. You could also go with tasker.
As for battery life, francos kernel is giving me 2 days of battery (far more than I need) with wifi/bt on, whatever apps need to sync do so and I have brightness set to auto.

I found juice defender good for phones that are bloated with crapware and not rooted. It hurt battery life when i used it for phones with custom roms and kernels.

Best battery saver is your self. These apps don't work any better than you doing the things it does manually. If its using resources which they all do to "save" you battery... Its not really saving you battery.. But in fact using it.
Some tips I suggest:
Turn sync off in everything. Go to data usage hit the menu button and uncheck auto sync data. Also you will want to open apps that have notifications and make sure they aren't syncing either.
Remove maps if you don't use it or disable it at the very least this will keep it from polling your location and wake locking the device.
Keep your running apps to a minimum and force stop any unnecessary apps.
Turn off Google backup services. Sometimes this will be pulling and pushing data wake locking the device and using battery. I've never found it necessary especially since I use TiBu anyways for my apps to restore. It never saves my WiFi password either.

After I turned 'Google location' and NFC off, this thing can easily last the day with average use. Before that it was just draining like crazy.

I've had juice defender ultimate since my Nexus S days. I wouldn't be without it as I can't get my battery to last a full day without it. When it's fully configured correctly, it works fantastic. I especially like that I can configure wifi to turn on and off automatically in areas where I have a saved wifi. I can decide the interval I choose for syncing data, and there are many other features. I'm not going to be manually turning on and off functions all the time, all that does is create more screen on time and is a waste of my time.
Bottom line, for me juice defender ultimate works because I spent time configuring it properly for my usage.

What's the screen on time though?
I can easily get 2 days of battery if I don't use my phone at all.

1.5 hrs screen on, 1.5hrs on call...I got close to 6hrs screen on when I did a drain test.
And no, I wasn't getting 2 days out of the phone stock with the same usage, it was more like 12-18hrs.

I tried using Juice Defender on a different phone and all it did was make the phone buggy with problems with wifi connectivity and other minor irritations and I could never configure it in such a way that didn't give me problems.
Are you having trouble making it through the day on one charge? I don't think I could use my N4 that much if I tried, I sat in a doctor's office the other day for 2.5 hours listening to Pandora on a bluetooth headset while reading a book with the screen on and still made it until I turned in for the night. Perhaps it is the Trinity kernel or custom ROM I am running, I never ran my phone stock so I don't have anything to compare with. I guess some of you want to go longer than 24 hours but it would be a really bizarre situation for me to need to do that.

So I tried juice defender ultimate and it did significantly increased my battery life. I am now getting about 30 hours or more with my regular usage. Even right now I have 63% remaining battery with 1 hour screen time and 17 hours total run time, see screenshot for usage.
