I had searched previously and read some things about this "bump" charging stuff supposedly getting you many more hours of usage on a normal schedule.
Actually, guess I should preface with some background info. This is my first android phone, but I've been watching since 1.6 came out. So, the day I got my Epic it was rooted and I flashed Nebula ROM on it. I also tried out Epic Experience, but was more pleased with Nebula. Of course I'm running DK28 with the modem fix.
On to my question. What can be done to increase battery life on a fairly undemanding schedule, without causing the device itself to operate less smoothly?
I tried several of the bump charging methods I saw, but I'm sitting at 33% battery after 5:45.
I'm going to feel dumb if this is actually average and I'm just expecting too much, haha.
Thank you, kindly.

You can try calibrating your battery. If you don't know how, well here's some instructions:
To do this, all you have to do is let your battery completely drain. Then while the phone is off, charge it for around eight hours straight without turning the phone on (have it just showing the battery icon).
Since you are already at 33% or so, I'd suggest just letting it drain today, and have it just charge overnight.
I, too, am running the Nebula Rom, but I haven't tested it for a full day without charging it yet. So, you can try calibrating the battery if you would like to see if you would get any improvement, but in my opinion, 33% at 5:45 sounds great. I'd be satisfied with that.
Please let me know how it all turns out.
Hope this helps!

Thank you for the speedy reply, I will try that.
I wasn't really expecting 33%, but more around 50%. I've only sent three texts today on it (as I was trying to see how well it'd hold up) and so I assumed battery life would be fairly high. But I am also living in an area with extremely poor coverage, so bad that it'll start searching for signal if I move the phone 2 feet away. So maybe it is trying to acquire a signal often.
I'll report back in the morning. Any other advice/ideas would be greatly appreciated.

Well, there's basic things as well.
Check to see if Data Roaming is on, make the brightness Auto, no live wallpaper, no bluetooth, no GPS, No background data/Accounts Sync.
But you shouldn't have to do ALL of those. Just a couple if you haven't already to boost the battery a little.
And yes, searching for a signal could be the problem.
And only three texts? Nothing else? Maybe there is something wrong.
Tell me the results tomorrow after calibrating the battery.
I'm using midnight rom and I'm at 20h26m and 33% with moderate usage. You can try recalibrate and wipe 3x b4 install the rom. It might help. Good luck.

Alright, it's 9:20 EST and I'm starting off with 96% battery life. I'll gauge how it holds up through "normal" usage, which is somewhat less conservative. Wifi will be on nearly constantly, my signal will be weak unless I leave, autosync is set to hourly with background data.
I normally get about 12-16 hours on what I call moderate use.
I leave gps on all the time. I make ~6-10 calls a day for 5-30 minutes. I send and receive ~30 texts a day. I'll put an hour or two worth of internet time per day. (not watching videos)
I kill the drm and friend locator services on every boot. This helped my battery life a lot.
It does help to train your battery dragon occasionally.

Are you saying to turn Data Roaming on or off? I could come up with a reason it would help either way, so do tell.
Same thing with Auto brightness, I would think that actually uses more battery than a fixed lower/medium brightness.
Do people on here really leave Sync and GPS off?
Compared to these settings, I'm completely lazy, and still get good battery life.

Turn off Data Roaming. The reason being is that with it on, your network will constantly search for data, and that drains the battery. The brightness I am actually not sure on. I have had better results with auto rather than, say, 0%.
If you get good battery life already, that's fine. But auto-sync isn't really necessary in my opinion.

Alright, it's been 5:33 since it's been unplugged and I'm sitting at 68%. This is with wifi on the entire time, brightness set to auto, and data roaming off (no need for it to be on, I was considering toggling it based on my location in Tasker). Sync is on and I rarely have use for GPS in my day-to-day so that is off.
So I think the calibration as recommended by Acer1096xxx has effected the life of my battery for the better. Thank you, once again.
Hopefully this thread will help others out in the long run. I'll continue to monitor my activity and battery life.
EDIT: 57% as of 5 o'clock. Had to plug it in because I'd be going out tonight doing things. Overall, this is about the performance I was hoping.
I'm noticing that battery life is worse in 4.2.2 - I was on cm10.1 nightlies w. Cm10.1 kernel and was getting about 10 hours screen-on time before I needed to charge, but I'm getting 7 hours at best on 4.2.2 stock (rooted, bootlader locked).
I have the usual culprits turned off - Google now, location services, currents background updates etc. So I hoped I would at least get the same.
Anyone else?

Yes! I just read that. I am just about to do it now.
I can't comment on battery life, but did notice something a little alarming with regard to battery drain. Was on the couch for an hour talking to someone using viber, just plain text. No video or audio. Tablet was plugged into the wall, and after about an hour i noticed that the battery had gone from 100% to 98%. Should not be possible for a simple messaging app to cause the battery to drain faster than it can charge. screen was on auto brightness as well.

Did you look at your battery information to see what was using the most energy? Display is always far and away the highest for me, and if it was on Auto Brightness, depending on the lighting around you, it could have been running at full brightness...which would be a pretty massive drain on battery.

Once the device reaches a full charge it cuts off the power draw to avoid damaging the battery. It's normal for it to hover between 97% and 100% while still plugged in.
I barely get 6 hours of use now.

I did not look at battery usage, but the screen was generally dimmed, where as normally i have it manually set to full brightness, and nothing was running in the background that would not normally be running, that is to say nothing other than android stuff, it's basically a tablet for internet, email and skype/viber while i watch films etc on my computer

Indeed, but this has never happened before and i typically run the device with screen on maximum brightness. on 4.2.1 it would always show 100% when plugged in, i never once saw it drop to 99% or below.
So without further analysis of the issue, it could either be that something is sucking more power, which would seem odd, or that the update has brought about changes to the way the device charges, or changes to the way the device displays the battery level.
Damn guys, I don't know what I'm doing wrong, but I'm jumping around in happiness when I manage to get over 6 hours of screen time lol.
I've been on battery for the past 12+ hours with about 6 hours 15 minutes screen time and still have 36% battery left. Battery seems at least as good as on 4.2.1.

Thanks, I've done this now, and get about 5~6 hours of screen time now with around 50% left.
My battery life has gotten considerably better after updating to 4.2.2. The biggest improvement is how little the battery life drains on standby...it's nearly nonexistent.
Sent from my Nexus 10 using Tapatalk HD
Standby has always been great for me. With stock rooted 4.2.2 I'm getting great battery life. Loses maybe 2% after 8-10 hours idle. In constant use I'm averaging 11 hours on screen. I have everything on and synced but as I'm indoors I stick to 30% brightness. Also, I'm mostly just browsing. With games the life would be less for sure. Totally satisfied with the battery life of this tablet. If yours is getting truly bad battery life I suggest you try searching for rogue apps. After that, try a complete reflash of the stock image which deletes everything. Another thing I've found that helps performance is setting the WiFi band manually. As I have a pretty good router that utilizes both the 5 and 2.4ghz bands I set mine to 5ghz only. I live in a town house and 2.4ghz can be pretty congested even after turning my antenna power up to 150mv or greater. The 5ghz band is pretty open. I'm getting load times on webpages comparable to my i5 2500k sandy at 4.5ghz and ssd with its 5ghz WiFi n wireless card. This is the quickest rendering tablet I've ever used.
As an aside, the complete re image to stock 4.2.2 from Google might fix reboot problems as well. It seems to do wonders for people with battery and other issues on early n4s. My screen on mine is new but the hardware is from launch day.

My battery life is significantly worse after the update. I flashed back to stock 4.2.2. It seems that the problem with mine is my tablet isn't sleeping. Android os is the highest battery user.

do you mean reducing the maximum cpu clock to 1.5 ghz?
I've had this phone for around week (off craigslist so it's been broken in) and I can't seem to get any sort of good battery life from this device. I mean yeah it's ok, max I've gotten is 2.5 hours sot with 10-12 hr standby.
This screen is from today so far. I'm already down to 40% and not even at 2 hrs sot yet. What's going on? I've tried Franco's kernel, fauxs kernel, and now I'm on matr1x kernel. (all with undervolting) I've tried carbon, stock, and now I'm on rasenjb.
I don't think I'll ever get to these 5 and 6 hour sot times with a day and a half of standby everyone is getting.. I bought this device because of how good the battery life I saw everyone was getting and it's been a big disappointment so far. I've tried almost everything and that's why I made this thread. Does anyone have any suggestions?
That's because everyone liked to install custom kernels, underclock, never use their phone like a normal phone and then claim 5 hours SOT which is total BS.
Expect 10-12 hours with 3 hours SOT, that's normal. I've gotten way better than that but only when connected to Wifi and almost no actual phone calls. Anytime you're on the cellular network expect 10-12 hours tops

I've seen a lot of screen shots with 4hrs + though. I guess it's only achievable on WiFi. I'm on HSPA+ for 8 hours of the day and then I come home and there's WiFi. So I'm guessing data is draining my battery throughout the day like a hog. Maybe I'll try out that screen off 2G mod that I saw. Thanks for your input!

double check settings/google/accountname.gmail .. make sure music sync is off/unticked
use wifi only or 2g if you must (set 2g only anyway even when on wifi, stops the phone switching towers all the time)
use custom kernel and undervolt (optional) ..most come standard with a bit of undevolt already
don't have lots of apps syncing all the time.. facebook ect
use aosp browser or similar and not chrome
don't use live wallpapers
don't play heavy games , use mostly for messaging and browsing

Don't be hating because you are in a poor signal area. I get 6hrs sot on wifi and at least 4hrs on hspa+. If you are in an area that is a weaker signal, like 3g and edge with only one bar, sot will be less. I am stock rooted, including kernel. If a person doesn't use the phone the battery will last a long time, but the sot will also be low. For example, 24hrs of battery life with only one hour of sot pretty much means the phone was just laying there and barely used. On the other hand, 10hrs of battery life with 5hrs of screen time means the phone was used much and faired good. Apart from sot, cell signal is the biggest battery drainer. When I go to my sis-in-laws, which is a very weak area, my battery steadily drains with my phone just in my pocket. *edit* I should also note, when at home on wifi, I'm also on my Microcell, so I always have a strong signal.

I usually get between 2.5 and 3.5 hours screen on time. Sometimes better, sometimes worse. You can use better battery stats to diagnose and try to kill unnecessary wakelocks. And yes you can under clock and sacrifice functionality, but rest assured 5-6 hours sot is not typical, even if some people can achieve it on a regular basis.

Yeah! Its true. Poor signal make your phone drain more battery.
If in your carrier the 2G signal is better than 3G. Set the phone to use only 2G network. (GSM)

You're not talking about real world usage. Nobody uses their phone like that. It's people like you that come into threads where regular users with genuine concerns and questions get ridiculed by some guy who has his "phone" set up like some friggin science project talking about 5-6 hours SOT.
Google Search: Nexus 4 poor battery life
About 12,600,000 results (0.19 seconds)
Google Search: Galaxy S3 poor battery life
About 6,310,000 results(0.24 seconds)
^that's half of the results and the S3 has been out way longer with millions more users/owners
Obviously the Nexus 4 has a sub-par battery for today's standards. Case closed.
I answered his question with real life facts, and you're in here spinning fairy tales feeding a delusion that he can go about using his phone like a normal person and get 5-6 hours SOT.
So yeah, you're lying IMO.
Having a poor signal doesn't cut SOT by 4 hours.
Yes, I forget, I'm not using my phone in the real world when I'm working on my science project. Lol. Sorry buddy, but I did unlock my bootloader and root in order to transfer app data from my previous phone, but I am running the stock rom, even odexed version, and stock kernel. I have syncing, nfc, wifi, and gps always enabled. The only thing I don't keep on is Google Now because I don't use it. If you bothered to look closely at the screen shots, you would see the constant strong signal due to my Microcell. When on a weaker cellular signal, it cuts into my sot. I use a Microcell because without it, I get a really crummy signal, so I know firsthand what battery drain is like. And as I stated, on cellular only, I get 4-5hrs screen time, worse if I'm in a really poor location. Idk where you get this 4hr difference from.

It probably is low signal strength killing your battery, I should have thrown in the fact that 90% of the time I have full signal. Flashing a radio is no biggie, just dont be stupid about it and kill power halfway through the flash. No need to wipe anything either. I think i saw some recovery flashable ones around here, but i like to use fastboot whenever possible. .48 is the latest official radio, with .54 coming from an international white n4. I'm on .48 and holding off until .54 becomes official before deciding to test it out, since .48 is golden for me. Test all of them, older doesnt mean worse and some people have better luck with the older radios.
It may not be relevant to your experience, but I was disappointed initially in N4's battery life too. Even after dialing down most automatic syncing, being very conservative with screen brightness, and other standard measures.
I installed wake lock detector. In my case, Dropbox was at the top of the list, with an inordinate # of system wake ups.
Turned out a copy of Dropbox on another machine on the same network was, with the 'LAN Sync' option enabled by default, sending out gobs of wake-on-lan packets and was waking up the N4 very often; something that would happen even without Dropbox on the N4, presumably.
Disabling Dropbox's LAN sync seemed to bump my battery life ~20-30%.
Google told me 10 - 12 hours continuous useage. I haven't had anything like that from mine.

I'm on .48 and holding off until .54 becomes official before deciding to test it out, since .48 is golden for me. Test all of them, older doesnt mean worse and some people have better luck with the older radios.

Thanks for the info! How do I check which radio version I have?

Why are you fairies arguing?
I got my n4 yesterday and battery seems decent. I was listening to spotify while driving and spent about 1.5 hours in the gym listening to it as well. Also throughout the day was messaging, Facebook, twitter etc. Not heavily, but every once in a while. I'm satisfied.

Hi guys,
I've had my nexus 4 for a bit less than a year now, and I really am not satisfied with the battery life, both standby and even so when using, ON MOBILE DATA. Battery life on Wifi seems not too bad, but on mobile data, whether the signal is high or low, the battery just goes down super quickly. Everything else about this phone is still rocking so nicely, so I was considering switching phone just for battery life. But I thought maybe I should consider asking here first, and also maybe trying battery pack too. But before I spend my money on a battery pack, do you guys know how to have noticeably longer battery life on nexus 4 WHILE DATA IS ON?
Thanks!
i get 4.5-5h screen on time constantly, with only mobile data, lte. battery life all depends on how you personally use the phone, how you set it up, what apps you use, and, very importantly, the quality of your phone/data signal. that phone/data signal can make a huge impact on battery life. anyways, using hspa+, i get around 4h sot. on lte i get closer to 5h sot.
Look at things that make your phone work more than it has to.
Do you need to report your location to Google to have them prompt you about a nearby business that wants a portion of your paycheck? (or maybe it's allowance). If not turn off location reporting. How bright do you have your screen? Do you have auto brightness enabled?
Google is your friend. Make use of their search tools and do some of the tips they talk about. No matter what you do, mobile data will chew your phone alive if you do not have a good signal.

Thanks for letting me know. How about standby time? For me, on standby with 3g on (not lte), probably 1% drop for every 5 to 10 minutes. not really sure 100% cause I never measured it. But for ex, on the road, if I check my battery life often, I can see the percentage drop super quickly. When using it, it plummets almost. lol
Does Nova launcher drain battery by any chance? I've been using nova launcher for a long time, but after I installed it for my sister on her pretty old GS2 last time, she told me she thinks Nova launcher is draining her phones battery. I'm not sure what other apps I have may drain battery. FB, and messaging apps definitely makes my phone wake lock more frequently, but I definitely need to get notification from messaging apps, so I can't greenify them. Same for apps like Wunderlist, where I need to receive reminder because they are important.
I just tried a battery saver app but it doesn't really help much..it's much different from when I first got my nexus 4 about an year ago. Back then, I don't know what I had installed but my standby time was extremely good on Wifi at least, MUCH better than my old GS2. But now it's as bad as that.
Do you use any battery saver app? any suggestions?
BTW, the max I get with a mix of 3G and wifi is about 2 hours. No games btw. Just web, google now, play store, app interaction, google plus, etc.

I've searched google a lot before, and they tell me battery saving tips, saving apps, etc that I am already familiar with. I've been using Android since cupcake. But they don't help much because some settings, I need the features, so I can't turn off, and apps they suggested, I tried them before, and I tried again today, but this battery saver app I used (had very good rating and high num of downloads) didn't work as expected. For ex. I tell it to manage both my wifi and data, and when I turn off screen at home with wifi on, it should turn off wifi and ALSO turn off 3g, but it only turns off wifi and it keeps 3g on, which will make my battery life actually worse. I tried with other settings, and it's not as helpful as I thought. Maybe some other battery saver apps are better?
Hello, just today I bought a brand new galaxy tab s5e. It works, but I'm getting very poor battery life. Every 4 minutes it drops 1%, so that would amount to just over 6 hours of on screen time. People are getting over 12 hours of screen on time. I tried factory resetting, but that didn't help anything. This is with wifi on and 70% brightness. I have the wifi only variant.
I'm getting like 10 hrs screen on. Also have WiFi only. But my brightness is at 30% approximately, so yours sounds about right.

I see, I was worried and thinking to return it, it just seems like all the reviewers are getting quite a bit more battery life than me. Do you experience any wifi issues at all? It seems the connection drops and reconnects sometimes.

My wifi seems on par with other devices. My wifi network isn't the best. Just using the Verizon router.
Wifi speed is faster if Bluetooth is off or not connected.
I have the LTE variant of the SGTS5e and can get a weeks worth of use out of it. As I only turn it on when I need to use it.
