[Q] Juice Defender or Superpower?

Which do you guys think is better in terms of saving some battery and not hindering my performance at all?

What is superpower

Neither, it is a placebo effect. Find the right kernel and change some settings in your phone. These are not needed.

Actually I run stock, and I can tell you its no Placebo effect, my battery without it ran up to 12 hours, but with it I can get close to 30. Its main thing is(for both of them) is that it shuts down your data when your screen is off, and only turning it on at certain intervals. When your screen is on the data is on. They both are about the same, I prefer JD, but have used SP. It is a legit way to save battery especially if your stock as well as rooted. Now app killers on the other hand...not so much.

You know with Sense that it has the data off built-in? Go to wireless settings and turn off always on data. When the screen is off after 5 minutes, I think, it cuts the data off till you turn the screen on. In fact, Juice Defender eats up battery for me because it keeps the phone from sleeping a lot of the time.

placebo effect? hmm i run a pretty good setup kernel is battery charging 132 and i use collin ph battery tweak and life is decent. just heard good things about these programs. I like the idea were mobile data is only on when im using it. makes sense but ud think the stock rom would do that by itself already? can anyone confirm or disprove that?

i have Juice Defender and Superpower installed on my phone and its working great

There is no reason to have both apps installed on your phone considering they essentially do the same thing.

actually he's sorta right, some of the time the fact that the battery saving program is open all the time cancels out the battery that the program saves. Best thing to do is flash a solid kernel and colin ph

Actually, he's sorta wrong. You honestly think that the app uses as much juice as the data connection?

Superpower does no polling at all, all state triggered and has some SetCPU features built in, like seeting to ondemand and max 400mhz.

I've been using juice defender since august when I got my EVO and the battery saving has been exponential. That combined with my 3000mAh extended battery and I get 4 days on 3g.

I have not used either but I hear good things about juice. The only reason I don't run them is I use google messenger so I need my data always on. Juice pretty much cuts down how often your phone polls from the servers (kinda?). Anyways if you don't need constant connectivity I would say go with juice

[Q] help with battery not lasting long enough on HTC EVO 4G...help?????

my battery is only lasting like 5 hours and i have bought 3 already and the same thing happens. I have a ballistic HC case, so i cant buy the big ones, is there any other way to make my battery last long.
ohh by the way i barely use it like maybe only texting, but nothing else.

Is your phone rooted or stock?

And what rom? Any background apps running?

Do you have a really poor signal and lots of stuff trying to sync? I have a horrible signal at my home and it will kill the battery really quick but at my office where I have a great signal it will last much much longer.

I have the same problem.... But it last more then 5 hrs, maybe 7-9... 9 being least used. I have notice it being a problem with this phone (from other users). I found a better battery at best buy for bout $45. Supposed to last 2x longer, ima try it out. Anyone have any input on this alternate battery... At bare minimum I'll have a back up.

If it is the platinum 3500 battery, it will be great. It's the retail version of the Seidio 3500. I picked one up a month ago. I originally bought a Laza 3500 from Amazon which wasn't much better than my stock 1500. I'm loving the Platinum though.

There are many factors that deal with battery life. Since you say you use it for texting, then you either have your phone on all the time or you are constantly turning the lockscreen on and off (I am a texter too). If you're rooted then try the kernels suggested above, they'll help BIG TIME. You can also try another rom; other roms just have great battery life. If you're not rooted, then set your phone to never search for wifi signals and only use 3G, GPS, and bluetooth whenever you need to.

Serious question.. regarding EVO batt life

So not here to stir up this post with heresay and sayso facts or not facts... But this is my 5 th EVO since released goin.. back and forth.. I was just curious if anyone knows of a fix to the teribble batt life.. goin on over a yr now...since released..and all the trial and error ... Talk on flahing kernels ..certain roms.. extended batterys.. even partitioning SD cards..
Now there's threads on latest OTA KERNEL including first real trickle charge on the device ...
So are they're any good fixes /links /ideas that cure the issue ..etc.. such as Rom/ kernel combo ? Anything

You should probably look into viperMOD. You can undervolt most AOSP kernels to save some battery but sacrifice a little performance. I actively use this mod and I must say it does save a tremendous amount of battery.

I mean, it all depends on how much you use your phone, and what you use it for. I keep my 3g on all day long, and using MikG I can easily go 2 days without charging. Before gingerbread, I was using Myn's 2.2, and I could easily go 3 days without charging.

My setup lasts all day without needing to recharge. And I don't have to turn off my data either. Flash various ROM/kernel combos, calibrate your battery, modify how often your widgets and services update, adjust display brightness, don't let erroneous apps run in the background, etc. Doing that to make sure your phone is setup properly has the single biggest impact on your battery life.
After you do that then you can start fine tuning with things like turning off your data/GPS service, using vipermod, undervolting, etc. in order to get even more life from your battery.

I've been doubting myself too much

to the point where I'm thinking of returning my Galaxy Nexus. The phone is beautiful and slick but I can't deal with the battery life. I'm especially worried for when I go back to my University next week because I'm not sure if the phone would last while I'm going from class to class from 9 AM to 5 PM everyday and most rooms having low to no reception.
Before this phone I had the HTC Thunderbolt with the extended battery and it could last me the whole day while I was going from class to class and under heavy and constan usage (to the point where I never had to bother monitering it or caring about the battery). I would have auto-brightness on, GPS, Google Latitude, use Facebook app freeling, have Google+ uploading my pics as soon as they were taken, use Pulse, and be ALWAYS connected to 4G without worrying about the battery life.
Now with the Galaxy Nexus I'm forced to turn down my brightness, turn off GPS, turn off Latitude (you can see where this is going. Pretty much opposite of Thunderbolt), uninstall Facebook and disable Google+, minimize my usage, and use Wifi whenever possible to get through a few hours. I even uninstalled Google Voice today to see if that makes any difference. Really? Why am I crippling my smartphone? Why should I have to turn off 4G on a 4G phone to save battery?
I'm obviously an idiot for comparing a Thunderbolt that has an extended battery (2,750 mAh) with the Galaxy Nexus that has a normal battery (1,850 mAh). It's also my fault for trying to believe that battery technology would improve in about a year especially after the horrible battery life from the Thunderbolt; I thought that people would learn from other's mistakes. I thought that the Galaxy Nexus, Google's new and precious baby, would fix the woes from previous phones.
I've been following a ton of forums to find out if there's a fix and I've done a bunch of stuff (disable Google+, uninstall Facebook, etc) but there's barely a difference. Some people are suggesting that an update will come along to fix the battery but I'm tired of hearing that excuse. A software fix will only do so much. And 4.0.3 has been announced for a quite a while from Google. Why hasn't this phone been update to 4.0.3? Why did Google halt it from the Nexus S? Is there something that's running down the battery even more with that update? I don't want to go off topic but I just hate being kept in the dark and not understanding what is going on.
Here I am now typing this as I'm looking at my Thunderbolt while it charges. I'm planning on trying out a few ICS ROMs to see how they go. I'm just tired of second guessing myself. The Galaxy Nexus is a beautiful device, both software and hardware wise; the camera may not be the best but I love it's speed and ICS is just sleek as F. But I can't fully enjoy the phone with the mediocre battery life that I am getting.

I suggest stock 4.0.2 with ogdobber's jamesbond kernel which only has undervolt open and the gpu oc'ed. Probably need to turn off lte and stick to the CDMA. 3g CDMA isn't fast but it is passable and battery efficient.
Sent from my Nexus in Texas.

even if battery tech does drastically increase 1750 mah will ALWAYS still be 1750mah it may take up less space or create less heat.. Mah is a measurement of milliamperes per hour

Try Paul O'Brien's excellent MoDaCo ROM - very impressive battery life and for $9 you get access to the kitchen. There's an update due today which will fix a flaky call issue.
Alternatively, hang on for 4.0.3 which is likely to bring some decent battery life improvements and bug fixes (though wouldn't surprise me if it's out for the Galaxy S2 first). I used to get 2-3 days of heavy use from my SGS2, get one of those and wait for ICS if you want better battery.
And a last alternatively... shove one of these in your bag:
http://www.firebox.com/product/2692/Pebble-Portable-Charger

If your in places with no reception, put the thing in airplace mode or disable mobile data.
This phone gives me the best battery life vs my last 4 phones,... HTC hero, htc evo, Nexus s, and htc evo 3d...

Get an external battery. Since you are in uni I suppose you will be carrying around a bag anyway so it won't be too inconvenient to lug around. Just leave your phone charging during lunch and it should last the rest if the afternoon.

Go into your sstem/app folder and take off apps that you don't use. EVERYTHING you don't use. if you take a trip to that folder you're gonna see a lot of **** that you didn't know was there.
Do some cleaning and you should be fine with your normal usage. Also, try to flash a kernel so you can customize the governors and allow the phone to sleep more efficiently.
Coming from a thunderbolt, you should know how horrible battery life is for ANY stock android device...
There's no need to gimp your smartphone. I fluffing hate it when people say "just disable 4g, 3g, take auto-sync off, turn brightness all the way down, and only surf the web with wifi"

Also to put it in context...I'm using the epic 4g and I still have the stock 1500 mAh battery and the only time I lasted more than 4 hours on stock without having to charge was with a gngerbread leak.
But after a couple days of devs getting dirty and taking the time to clean up, your battery should last exponentially longer since people will have figured out what exactly drains the batter and how to stop it.
On the epic, it was the DRM. **** always ran in the background, then someone discovered it and about a month later it became so irrelevant since all the devs knew what code to get the drm to stfu until you needed it

Battery lasts me all day on the GSM version.
Folks, powering an extra radio uses extra power.
Moreover, the longer your data connection stays active, the longer your radio is active which is an even bigger drain. Since the LTE Gnexus devices are powering 2 radios (CDMA *and* LTE) simultaneously, and the second radio isn't as efficient as the standard radio that's part of the SoC package, this means that you need to ration your data usage if you want your battery to last.
Again, on the GSM version this isn't an issue because the radio is built into the SoC from the ground up, as well as it being only a single active radio at a time (GSM *or* UMTS/HSPA).
Software updates won't change that. It's a matter of physics. The LTE version may see some improvements here and there, but no software will counteract the effects of having to power 2 radios constantly.

Lol its definitely not like that. Its more like buying a new eco lightbulb that you use just like your old lightbulb but your bill is $80 more. Wut? LOL
But nah my epic 4g lasts me the whole day with 4g on (no access to wifi :[ ), auto-sync for gmail (i don't use facebook so its always the first app to go), blah blah blah. The only time battery is a problem is if I'm in a no sprint zone and forget to make my phone roam. Other than that, its used as a smartphone with 3+ hours of screen on time (voodoo color allowsyou to edit the gamm values and what not so its able to sip less power for the same brightness if that makes sense)
Seriously, root your phone and if stock is your thing, just install a custom kernel. Kernels handle the voltages and frequencies andhow your phone interacts with certain things so a custom kernel will almost ALWAYS have been optimized over stock. You will probably see a muc better result if you flash a ROM and Kernel, simply because custom roms are made to work without all the extra **** running in the background that no one wants

Just to clarify, make sure you KNOW what you're deleting and make backups anyway, just in case something you remove from there causes issues with another application that expects it to be there. Sure, you can remove a lot (if not most) of things from system/app without harm, but don't just go deleting random things unless you are SURE there will not be side effects.

[Q] What are you currently doing to increase battery life?

We all know our GS2 runs out of Battery at a faster rate than what we would like! I'm just curious, what steps do You take to increase battery life, if any.
-Do you use certain apps?
-Do you enable/disable certain things and certain times?
-Anything, ever the smallest things you do, I would like to know!
I'm just curious to see what different people do to strengthen their battery.
(Also, if you could, please just post what ROM you're running on too) Thanks!

Battery Life
Im running FK23 leaked rooted with stock kernel. I use powersave mode that comes in stock settings app.
I don't limit cpu. I use phone to txt, play games, youtube, facebook, twitter, and instagram and google play store.
I get around 14+ hours usage.
Also, I try to use WIFI whenever I can. I turn off GPS when not needed. I dont use 4G often as 3G is pretty good on FK23.
Lasts me from 7:45AM to 10:27PM as of now on 1%.

Wow, and how much do you use you're phone throughout the day? I'm just looking for new ideas because I do several things to increase my battery length, but I find myself around 50% in the first 2-3 hours of my 11 hour day. :/

I bought a cheap ($10) extended battery and cover, and a cheap ($9) TPU case/ At 14 hours, I still had 61% battery left. I can get a full legitimate day out of it running 2.3's, but I am going to try JB and ICS again and see where it's at.

I run KingKang with the JB tweaks package. I also modified my build.prop for both performance and battery life. Plus I toggle my 3G on only when I need it. If I have a WiFi signal I'll do the same with that. I average 17 hours but sometimes I get more than 24. Inverted apps not only look great, but help with battery too.

Honestly? #1 thing I do is stay on wi-fi as much as possible. Have gone almost 24 hours if I keep off 3G/4G and moderately use the phone/'net.

We all know our GS2 runs out of Battery at a faster rate than what we would like! I'm just curious, what steps do You take to increase battery life, if any.
-Do you use certain apps?
-Do you enable/disable certain things and certain times?
-Anything, ever the smallest things you do, I would like to know!
I'm just curious to see what different people do to strengthen their battery.
(Also, if you could, please just post what ROM you're running on too) Thanks!

I switched back to Calkulin 3.0. Battery issues solved.
I tried to make ICS work for a couple months, but grew to hate the phone. It's a much better phone when it runs Gingerbread.

I did the same as you until the fk23 leak came out. Calkulin's v3.0 gb is amazing for battery life, smoothness, and functionality. I was never fully satisfied with any of the ics solutions, stock or custom.
Although the fk23 battery life isnt as good as calkulin, I'm still using it as my daily driver bc it's jellybean and cool, the phone runs well and smooth, and battery is good enough for me.
To answer the op's question, I do the following to help extend my battery life:
1. Leave off all data unless I need to use it (3g, 4g, wifi).
2. Turn of autosync and only sync as needed.
3. Remove bloatware and/or freeze any unnecessary apps (use GSM battery and OS monitor to find battery hog apps).
4. Leave off GPS unless needed.
5. Set screen brightness lower.

Here's a link to my FK23 results over in the battery thread in General:

I've only owned this phone since after the ICS update, so never tried any GB ROM.
The ICS ROM I've had the most success with is Re-Calked, but FK23 takes it just a step further for me. I know some people have been reporting issues with FK23, but for me it has been rock solid and has been my DD for nearly a week now.
Blu Kuban also did well with battery life, but it is a little over-customized for my liking. I also had some stability issues with BK. I used sleshpics M'ICS build for a while too ... again, over customized for my liking. Good performance and relatively stable. Also, I have never been able to get 4G speeds on any other ROM/kernel like I'm seeing now.
If I'm in an area with a strong cellular signal, I can get over 24h with 3h+ screen time both on and off WiFi. If the cell signal is week, I burn from 5-7%/h so maybe 15-16h if I was there all day ... but that would obv. improve if I threw it into airplane mode.
I have frozen all of the bloatware apps, don't have Google Now activated. Other than that, I allow syncing to occur per default. I don't have FB app installed.
I use auto-brightness most of the time, and I have a dark wallpaper.

dim screen. stay on wifi. that is all.

Honestly, getting use to a dimmed screen made a HUGE difference!!

Is there ever a time when its better to not be on WiFi, of a WiFi is available?

I have had huge battery drain while being on wifi when availible 100% of the time I only use wifi when I need a faster connection

Wow, and how much do you use you're phone throughout the day? I'm just looking for new ideas because I do several things to increase my battery length, but I find myself around 50% in the first 2-3 hours of my 11 hour day. :/
