Just installed JuiceDefender and I am now getting ALOT better battery life. I also don't think signal effects it because I am in a low signal area. One underneath on the widget is time since last unplugged, and you can see in notifications area the %'age of battery. Have been playing music, browsing internet ect, just using it moderately.
i36.tinypic.com/73ed10.png
Best record so far before getting down to 10% battery life is 25 hrs 48 minutes.
Sheeeiit. I'm lucky to get a full 12 hours on a single charge. So far. Only been through three full battery cycles so far.
2 days without problems.
Surfing, calling, WiFi, playing games, camera.
With really heavy usage like massive calling and browsing, it's was drained in one day.
Not long ago, first day low usage (FM radio, a bit od camera usage, couple of calls), lasted three days with 20% left.
nahhh ... i guess u r using a Mugen Power 3200mAh extended battery
otherwise impossible ..
wat firmware, rom, lagfix , progs are u using that gets u near to the end of the second day??
The biggest battery killer is 3G. Turn it off when you don't need it and you'll get quite nice battery life boost even without installing annoyances like Juice Defender. With 3G, my battery lasts hardly a day of light usage. On 2G, I can get two, maybe three days of light usage. Most of the time I don't need the 3G speed anyway, 2G is fast enough for a lot of things.
You might also try deleting battery stats and/or leaving the phone to turn itself off and then letting it charge until it tells you it's fully charged (you may turn it on after you've connected it to the charger, but not before that!). That way you'll calibrate the battery meter to your battery capacity properly, so it won't lie to you.
Oh yeah, and contrary to battery theory and logic, your battery WILL improve quite a bit after a week or two. Three cycles is not enough. Just be patient, give it time.
how do you switch from 3G to 2G? noob here.
Settings, Wireless, Mobile networks, Network mode - GSM only is 2G only. WCDMA is 3G.

Stock battery, G7.
You can see in my signature which ROM I am using, it's stock JG5 with no lagfix.
First couple of days since I bought it, I was very disappointed about battery life (previous HTC Touch HD lasted 2-3 days).
I came so far that I set wallpaper to black and even then it didn't last much more than one day. After some time battery life extended and it became quite better, even with Nexus live wallpaper.
3G is OFF in my case, I am mostly on WiFi when I need connection, but GPRS / EDGE are always ON.
I use 3g and battery is ok unless I play games.easily last 2 or 3 days on standby with a few short call s
1h Or 2 With games lol
I have quite bad 3G reception at home, living out of town.
At work it's ok, but I rarely need 3G so there's no problem.

Part of this depends on how your carrier acts. If I turn off 3G it means I can't use data, I can't sync etc. Sync & applications launching and background data is a bigger battery drain...multiples higher than 3G in my guess. EDITAccording to GSM arena, my 2G/3G talk time was way off, but I think their data is old. I'll remove it for now and replace it with "Up to 750 h (2G) / Up to 576 h (3G)"...it's not sooo much the network as what is going on when you might be connected to that network.
edit 2 GSM arena seems to have the most recent info, I thought they were approximating this from their test units.
Just fyi for those unaware.... Bell is a 3G only network, nationwide. You can't disable 3g on Bell and still have data.

I'm also using Juicedeffender and my battery live improved a lot. Now I can run the phone 24-30h without charging.
Is it just me or is it getting old with everyone CLAIMING "best battery life" when you usually end up with the same or worse than a stock HTC kernel?
I have tried NetArchy, KingKilck, and a few others only to have my phone die in the same amount of time or even sooner. Why is this? Well what you all don't do is take into account the MANY different variables that affect battery life.
The thing that tanks my battery the fastest is the fact that I work in places with low (10-30%) signal. This kills the battery because it is constantly searching for a signal and talking with the cell tower. I am willing to bet most people that have bad battery life are in low coverage areas. I simply have learned to put my phone into airplane mode and have people text me on Google Voice as I still have a WiFi connection. WiFi uses FAR less power then the cell radio in low signal areas and you can still maintain connections if you have everything setup right.
I am NOT in any way bashing the work and effort that has been put into these kernels but with the latest HTC kernels having unlocked FPS and great battery life why would I want to even mess with a custom kernel? The only reason I could see is for overclocking. I wouldn't even run one for underclocking as I have found this to NOT be an effective way to prolong battery.
Just thought this needed to be said. What I have said here also applies to collin_ph tweak. There have been many reports of the "tweak" killing the battery even faster and I have verified this.
Mostly true, but I think it really depend on what rom, and kernel you are using, plus your signal strengh.
I've flashed very often since the day I got the phone to get maximum battery life out of it, and netarchy's usually worked for me.
I've also tried stock/default that came with Myns 2.2, and best combination that worked for me are Myn's 2.2 and Netarchy's 4.2 cfs havs smartass more agressive kernel.
there are too many kernels out there and you just have to find a working combo that works for YOU at the end of the day buddy.
Oh and I totally agree with you on this thread that it does get annoying/frustrating to see these threads, and you decide to go with it, and it turns out to be a crap.
I've tried a lot of things and never really gotten better battery life than stock, but I have gotten about the same with better performance, which is good enough for me.
The only thing that really improved battery life for me was butchering the phone - turning off background data and auto-sync and using JuiceDefender (disable mobile data when the screen is off, turn it on for 1 minute every 15 mins). But I decided I prefer using my smartphone as a smartphone.
I've come to accept it. My average battery life on weekdays is 8-10 hours. I wish it were 12-14, but I can live with it. When I stay at home on weekends, where I have Wifi and good cell signal strength, I generally get 20-30 hours with moderate use.
I live with plugging my phone in at work, and I got some of tuttoit's cheap batteries off eBay. It works well enough for me.
Anytime you flash a custom kernel you have to give your cpu time to adjust to the new stuff included (havs,bfs,cfs,voltage...etc..)your battery life gets better days after using these new kernels not immediately after flashing...
i have flashed myn's 2.2 and using setcpu to underclock when in black out mode and using titanium backup to "freeze" apps that somehow start themselves. my batt life has gotten way better than what it was on stock os and settings. ive also tried to do the *#*#4636#*#* and cant get into testing mode to change from gsm to cdma but im willing to bet its on cdma anyway.

You can use Roam Control to force roaming in those areas, if they have good signal strength with another carrier.
It's the same power usage as in good signal strength Sprint areas.
im still trying to find the reason for my battery drain, i get an ok battery life with heavy use, but even at idle it varies, the other day battery stated 80% all day long, i ran it down as best as i could and got it to read 10% at 4:30 in the morning, i set it to charge, wake up, unplug it, go back to sleep, wake up only a few hours later to see that my battery reads 60%, im sure that nothing out of the ordinary was running, i cant seem to figure it out, and i have done 3 hard resets to try and find out whats draining the battery, seeing how it varies and is seemingly random at times, im starting to think it may be the radio
I would highly suggest buying a extended battery. I have complained about the battery since day one. Got the extended battery at sprint for $54. I went 8 full hours.. I mean 8 FULL hours hard usage. I turned the screen off 3 times. Wanted to see how the life would be since I used to be on my for for aboutt 3 hours and it die.. today tturned on phone at 9. Its almost two.. 93%.. I did have my brightness all the way up yesterday and overclocked at 113 on interactive.. tomorrow ill turn everything on and run it hard again.. ill turn my airwave off also. I will get worse reception than u would at work.. -115 to -120.. I hit -125 already but I heard -120 is no service..

Sorry but I like my evo to stay thin. X)
Same here.. but the extra thickness isn't really much a bother to me as much as charging and carrying 2 extra batteries. 6 hours now and at 75%.. I love it.. and glad I got it. Just hope when I get a different phone I can use my extending for it. Like I had tp2 and same batteries as the evo..

So I notice that an hour on wifi surfing the web took about 20% or more of thE battery...even playing game doesn't do that to the battery. Anyone experiencing similar thing? Anyone with 3g, is data looking the battery too?
Just keeping wifi turned on is also drains the battery for me.
Check your screen luminosity.it is the biggest battery killer
I'm running the Moto234_eVo_Carbon_V0.3 build and I've noticed that even with the screen off and the phone idle my battery drains at a pretty good rate when compared to WinMo. Any fixes for this?
for me 3g/h draw much power than wifi, almost 1.5x-2x of the wifi surfing..
Screen brightness is easily the biggest batter drain keep brightness as low as possible,
Data connection will hog more than WiFi if you are in an area of weak signal and your device is constantly searching for a signal, when your at home or work using WiFi just turn data off and switch to only 2g networks, set setcpu to screen off 245 245

Screen brightness definitely hits it hard, then wifi and bluetooth, keep em off whenever you are not using them and of course apps running in the background, grab a task killer, if its not needed, it shouldnt be running or else it will use power.

Get "current widget" from the market to see how much powers are being used. While screen off, my phone only drain about 4~7 mA...
I just came across this. Super detailed analysis of battery usage.

3g draws much more power than wifi. If wifi is available use it over 3g. But like others have said, the screen is by far the biggest battery hog.

I don't see how the screen is the biggest energy hog. When I leave my phone uncharged untouched over night and it it displays 7mah on current widget, I lose 40% battery in 7 hours.

That's unusual...i lose less than 10% over night...even with bad reception in my room, that didn't kill my battery. Maybe you can try this to test it out. Fully charge before you go to sleep. The next morning, check your battery in setting to see what is using the majority of the battery drain during that period...this might help you find the reason...
If noting else is running, Cell standby will eat the majority of the battery power.

Wow, I installed Mdeejay_eVo_Sense_v_2.3Revolution to see if this build helped on battery life. I charged my phone over night and had a full battery at 11AM (according to the meter) but by 7:30PM, my phone was completely dead. During this time, I had two 5 minute phone conversations and used GPS for 9 minutes. Other than that, the screen was not active and I didn't have WiFi enabled. Is this typical? Doesn't make running Android very practical on the HD2. This is only the second build I've tried but it's not looking very promising.

Something is wrong with your build. Try his newer build. They got a new kernel. If that were my habits, my battery would drop by only about 25%. You should install "current widget" from the market. It help you keep track of battery usage. On standby, most people and I got about 3~7mA. If you get a higher mA, that mean something is eating your battery.
Please give Mdj's New Build "Froyo Sense Revolution 1.6" that comes with his new kernel which is suppose to make battery last longer. Hope this helps.

i hope this enlightens you and yes wifi kills battery but it is not the biggest battery killer and wifi is more harmful to your battery life if it is not connected which means it is constantly searching for a network which sucks the life out of your battery.
I think the wifi modules on the new kernels (Hastarin > 8 & MDJ) are consuming too much power.
I usually got 5 ~ 8 mA in sleeping mode with my wifi turning on on the previous kernels, but now I got 8~60 mA and the battery status is showing that wifi is taking about 30% of the battery. Maybe this is because the 802.1n is enabled by default!
Any Singapore users here with rooted/custom ROM'd S2 still experiencing heavy battery drain with fairly normal usage (occasional web browsing and playing games, maybe 3-5 photos - battery dead in less than 8 hours?).
I've noticed that here in SG, my 3G signal keeps on going off and on, as if the phone is constantly trying to reconnect to a 3G signal (SingTel has been pretty bad for me, especially while walking around town). I've turned it off to 2G only and my battery seems to have improved.
Anyone else in SG have suggestions on how to improve battery life?

Im from SG dude my phone can last for 16hours with 3h-4h screen on. Its pretty decent. Change your modem. Im on LPX. Dont use FB app if you are using one. Its a huge battery drainer. Use BBS to find out what else is keeping your phone awake/draining your battery.

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?
