Do you use battery saver apps?

Hello everybody
I would like to know from you if battery saver apps are usefull or just useless.
I am using right now super power and i think it could save some energy but it is also quite annonying for example to wait for the band switch.
It is worth to to deal with this apps or you doesnt care about the energy you loose and enjoy to have no troubles with such apps.
Just out of curiosity which battery saver app you use when you use one?

I use Juice Defender Ultimate and find it to extend the battery life a whole lot.
What it does is automaticly turn off data comunications when the screen goes off. It then turns data back on once every houre to let the phone check email and stuff like that.
You can customise almost everything. I really like it and would recommend it to anyone.

Since I started using Green Power Premium, I find my phone on when I wake up in the morning

I too use juice defender, at this moment tells me my battery life has increased by x1.87
what that translates to in a percentage i dont know but hey !!! it saved some juice.
all these apps do is just make it quicker and easier to toggle things on/off, you could do it yourself but why waste time when the app does it for ya ???
some may argue that the app is constantly running in the background therefore its hogging battery, but too be honest, all you can do is try and see for yourself.
BUT !! i would recommend them to any one, Mainly Juice defender and some sort of toggle widget. hand in hand they work well

No battery savings app here.
If you prefer battery life over fancy looking screens (like myself), just get rid of all the constantly updating widgets and crap like that.
I managed to stretch my battery life to a consistent 48 hours per full charge. And that's with an average of 2,5 hours display on and a lot of listening to PowerAMP.

I just removed bloatware with titanium backup, set my wifi to sleep when the screen goes off, and lastly use setcpu app to downclock with certain profiles. I get excellent battery life now.

Any one compared battery life with always wifi-on vs juicedefender control wifi?

Hey guys, I'm considering to maximize the battery life, but also be able to get email in time.
Two options: 1.Disable juicedefender's wifi control, which allow wifi runing all the time while screen-off.
2. Set juicedefender control wifi, scheduling activate wifi every 15min for sync(ping).
It seems that option 2 should save more juice, but every time activating the wifi probably consumes more power.
Anyone has ever compare this two method?

i have used both, and spent hours tweaking juice defender - it DOES save battery, but for wifi its not enough to make it worth while imo
data uses a LOT more battery, so it may be worth while to let JD just control data.

I was using JD on default Sense 2.1 but have since stopped using it with CM7. If you really want to see big change to your battery life I would recommend changing your rom.

Battery drainage on Galaxy Note

Well, hi guys, I have been a member on this forum for quite some time but due to bad memory I forgot my account so I made a new account, that's not my point of this topic.
I bought a new Galaxy Note and I simply love it, awesome phone, but I noticed something wrong. Yes! the battery...
My battery simply dies in 2 hours of usage (videos or listening to music while playing Wordfued)
I want a solution for that, I have my warrantry and all, shall I demand a new battery or something? I'm Swedish by the way.
And I'm sure you'll ask me about flashing a rom and root it.
I know that would make the phone faster, but I'd rather wait for the official ISC.
Only if I can do both of the things at the same time, if so then I will flash, please do read everything so you can watch from my prespective, thanks in advance.

That's definitely not normal. I get much, much more usage doing the same, so I would definitely try changing battery first and then changing the phone as a second option.

Fully agree.
I would get 4 to 5 hours of continuous use, I reckon. Some people report more.

I think the problem is with the battery. you can try this :http://www.amazon.com/2600mAh-Batte...I84K/ref=sr_1_4?ie=UTF8&qid=1329085625&sr=8-4 . Just bought it and it give me like 6-7 hours of watching videos.

Thank you for the link. I was looking for a better battery. I home to find a vendor that ships to France though.

Thank you

Thank you my dear sir, I'll take that as the second option, I'll try getting a new battery since my warranty is vailed for 2 years.
Thank you though

No need for an extra battery or extended battery.
Install juice defender
Leave brightness on auto
disable 3g (it is on by default I believe and I noticed a big savings on batt %)
disable auto screen rotate(optional)
my phone is @ 44% left , lasted 11 hours 2 minutes , This will last me another 5-6 hours.
Did about 1 hour of gaming (myth defense)
30 min browsing on wifi
45 min on tapatalk
1.5 hours on the phone
1.5 hours streaming music to my desktop via kies air

I had posted something like this before...
1. Flash and test different kernels in case of battery drain. Some are easier on your battery than the others.
2. Use Titanium Backup to freeze or uninstall crapware. This list is a useful guide as to what can/can't be removed from your system: https://spreadsheets.google.com/spr...SENVeXlqUm5vV0E&single=true&gid=0&output=html
3. Set Brightness to low value, disable autobrightness
4. Disable or scale down vibration and haptic feedback
5. Automatic syncing of your accounts is battery consuming. Sync manually if you can
6. Set screen timeout to 15 seconds
7. Disable fast dormancy (dial *#9900# and do it from there)
8. Don't keep your WiFi/Packet Data on all the time. However, if you must have WiFi on the second you wake up your phone, go to Settings/Wireless and Network/Wi-Fi settings - once in Wi-Fi Settings, hit the menu button (the bottom left one), choose Advanced/Wi-Fi sleep policy/When Screen Turned Off. This way your connection will toggle on/off depending on your screen on/of state
9. Disable location services via wireless networks - are you travelling that fast that you need those?
10. GPS is heavy on the battery, therefore use it sparingly
And don't use Juice or any other battery 'defenders': they keep running in the background and consume your juice by trying to save it. Not to mention other problems they can (and often do) create.
Hope this helps.

I have found this too, although YMMV.
I use Llama (Location Aware Mobile App) to turn things of and on when I move about. I seems to work very well mostly:
1. Got rid of useless apps, and kill all listeners on new apps so they do not pop up (require root)
2. When at home or work, WiFi is on but sleeping when screen is off (this is the one that fails most often - need to monitor), data is off (to prevent use when WiFi is sleeping).
3. When out and about, data is on, sync is off (to save mobile data & battery).
Like this I can get very flat battery level graphs when the phone is asleep, which is what I want.
When the phone is awake, the only thing you can do is turn the screen auto orientation off (I use Llama to turn it on for certain apps), and keep the brightness down, and use dark themes for everything, really. Turn WiFi off when not using it would also help.
I just wish they had made the battery larger & thinner (as someone else said) so that a thicker battery could have been more effective still, like triple the capacity

Try disabling GPS, wifi and data connections when not in use to save battery. Also you could flash the latest abyssnote kernel. It has absolutely amazing battery life.

Getting the most out of your battery

Ok going to try and start a conversation here to get feedback from everyone on what you guys do to get the most out of your battery. I see alot of people always asking what kernal is best for battery life and some people seem to have horrible battery life and some have exceptional battery life. I personally get decent battery life. Nothing super amazing but that comes down to the way I use my phone.
My current battery I'm using - Andida 2000mah battery
http://www.ebay.ca/itm/280843217453...X:IT&_trksid=p3984.m1497.l2649#ht_4497wt_1396
I also have - GTMax 3500mah battery
http://www.amazon.ca/GTMax-Extended-Battery-3500mAh-Microfiber/dp/B006VAP102/ref=pd_rhf_se_p_t_4
The Andida gives me generally a extra 2-3 hours more over the stock. I had to cycle the battery 4 times before I started seeing any real improvements. If I take these off the charger at 6:30am I can ussually make it to around 10pm without needing to charge.
The GTMax get me through a day (630am - midnight) with around 50% left.
Now keep in mind this is based on my usage habits, and when I'm at work my signal is horrible so it drains a bit harder for the 8 hours I'm at work.
I don't have LTE where I live or work, I do get LTE in areas close by but on a regular day I don't see it. With the bad signal at work I've started to switch to gsm only mode (phone was constantly switching from Edge to 3g/4g and wouldn't provide a stable connection most of the time). This seems to have helped my battery at work.
When I flash a new rom I always give it at least 2 good full battery cycles before judging the battery life on it.
Ok onto some apps. My first foray into getting better battery life started with wanting to control my data. I used Juice Defender to that but I found that having to wait for the data to turn back on was at some times taking way to long and even sometimes I would have to reboot to get it back. Tried a few others and had similar experiences. When it works its nice and I did see some gain from it but at the same time it seemed bloated and slow and I decided I like having my data on and readily available quickly. After some searching I found an awesome app...
Better Battery Stats

I highly recommend reading up on this app and trying it out. If your seeing a big drain on you battery while the screen is off, it's probably because there is something that is keeping it from going into a deep sleep mode. This won't save you any battery just by installing it but with a little work it can make a pretty good difference.
Ok now this is where I'm looking for suggestions, are there apps that you find specifically run smoother or are lighter than their stock counterparts or rival apps that put less of a strain on the battery?
Instead of the stock messaging app I run Pansi SMS. It gives me a few extra options but I never really used the stock mms on ICS so I can only compare it to Handcent SMS and I think it is definitely lighter and a lil bit more battery friendly. It's not a huge difference but I try and squeeze everything I can w/o giving up functionality.
For a launcher I'm running apex right now, but for a lightweight launcher I'd recommend FTL. Runs really nice and smooth, nothing fancy about it, just fast and light.
Some apps sometimes can just be poorly coded and thus have a bad effect on battery life. Alot of people seem to feel the Facebook app is one such app that suffers from that. The app that gets the most recommendations as a replacement and being a bit easier on the battery is Friendcaster. I tend to agree with that, and would recommend trying it out.
I'd really like to hear about what everyone else does to try and squeeze out the most of their battery. Theres more stuff that I do, such as reducing the amount of things that are synced to only the stuff I actually want, default settings just sync everything and I don't feel I need to sync my contacts on a daily basis as I rarely change them around. So share your tips, experiences good and bad with apps in regards to your battery, and if theres enough feedback I'll try and re-organize this into a bit better structure.

I personally always leave data off. WiFi is on a lot. I wrote this:http://forum.xda-developers.com/showthread.php?t=1631831
I am very please to get a day and a half with the extended battery. Generally I am always texting,also.

Right here, this is the key. I have data off all the time. I only turn it on when I need to look something up or browse. IMO auto updates really kill the battery and aren't worth leaving your data on all the time. I'm on wifi a lot as well. Currently I'm on DarkRaider and I'm ending the day with around 30-40%, great improvement over stock.

It seems that with every new handset that comes out this is one of the hottest topics but the parameters all always the same with regard to battery life.
The 3 biggest things that drain our batteries are Display Usage, Data Connection & Radio Cell Connection. These are listed in order of current used. Of the 3 we can have some control over the 1st 2. Lower screen brightness and disconnect data when not needed and use wifi when possible. While wifi does use a good amount of current it's not as much as mobile data. The last one, Radio Cell Connection, we have very little control over. It's also the reason we see people having great differences in battery life. The further the phone is from the tower it's connected to the more juice it needs to make a good connection. So other than leaving the phone in airplane mode or planning your life around where towers are, neither of which are very practical, there is not much we can do there.
To get the best all around life from Li-ion batteries do not fully discharge them very often and also don't keep them plugged in after they're fully charged. It's best to recharge them when they get down to 20-30% and unplug them after they're charged. They also don't need to be fully charged every time, they have no memory. If your on the go and can only leave it plugged in for a short period of time that's fine. Also if you have more than one battery and your not going to use the 2nd one for a while don't store it at full charge. drop it down to 50-60% before pulling it out.
I'll update this post when I get home tonight with more info and links. Hope it helps.

I always make sure my auto updates are off. WiFi isn't an option for me when I'm working. How do you manage your data connection? Do you manually turn it on and off or use an app? I never really tried manually turning the mobile data on/off, just found with apps like JD that it sometimes took way too long to establish a connection. I always shut off my wifi when I leave for work. I know with ICS the widget toggles for gps don't work, they take you to the settings to turn it off, is there one for mobile data?

With my 3500mah battery I don't really worry about turning anything off. That thing is great. Made a bumper case for it but I miss having a real case on it so I picked up the 2000mah andida battery so I could get a few more hours on some days. If someone ever made a real case for those big batteries i'd use it all the time.

Try 2x Battery from the store. It will shut off data as soon as the the phone sleeps, it reconnects at screen on after unlock almost instantly. It also allows you to white list apps, like Pandora. The free version only allows 1 app though.

The DarkRaider ROM I am using has a nice extended settings menu in the notification bar with a data toggle. I also have a nice widget from switchpro widgets where I can customize what kinds of things I want to be able to toggle from my homescreen. Currently I have data/wifi/vibrate-silent/gps. Doesn't take long at all when I toggle the data on/off, it's pretty much instant.

I use the 2X Battery app. When the phone goes to sleep, the app turns off the data radio. I can still get calls and text messages. I don't have a need for push notification of e-mail, etc., so this saves me some battery usage. Of course, if e-mail and other app notifications are important, this app will help only if you are willing to wait until you wake up the phone.

Here's what I do. I'm on the stock HTC battery.
I SetCPU screen off to 192/192 ondemand, in call to 810/192 ondemand, and regular use to 810/192 ondemand.
I listen to about 2 hours of music a day, have 3 GMail accounts on autosync, a Facebook account on hourly autosync and HTC Weather on hourly sync. Automatic brightness. Roughly 1.5 hours of cumulative web-browsing, no apps/games used.
I never use WiFi and I don't live in an LTE area.
I typically end the day (19-21 hours unplugged) with ~40% remaining.

Now I am not sure if living in area with LTE is a bless or curse....
I would unplug around 7am everyday, and by the time I get home (around 6pm) I would always in red mode (meaning, it is either 14% or under). Using the Holics-0.6 with the kernel that came with it, battery seems to die fast. Even when I am on the stock ICS before this, seems LTE would just bleed this baby to death....
Reading other comments, might as well start looking for a bigger battery....

It actually seems like I'm getting better battery since LTE came to my town. I'm on dark raider using kozmick's rc1 kernel and it's even better now. Try turning off vibration feedback...I think it's located in the sounds menu in settings. You can also try using automatic brightness or even just setting it to stay at 50% or lower. The screen is a battery hog. There's a stickied thread somewhere on here that has other things you can try too.

Really is a shame that we have to disable or ease everything back so much to get through the day on a battery. Anyhow, I have a Velocity (which comes out of the box with the processor running at 1500) on Dark Raider. Therefore I use SetCPU to throttle the beast back, depending upon the circumstances. It only is allowed to run at 1500 when on charge and down to 400 when battery below 25 percent. I also use 2X Battery to take care of the netowrk and Wi-Fi and have purchased the andida battery for extended life. I also have JD installed, however it is rarely used - reason is that I am in agreeance with "citsong" that it takes too long to establish connections, even causing me general connection issues from time to time. So for around $25 AUD you can get through the day on a battery with moderate use and reasonable performance. I have not tried the extended battery pack, though I will probably get one of those as well...not sure which are the best???

I personally don't like the vibrate response thing, so I turn that off right out of the box, also, auto brightness is another that I set. When I go in the battery tab to see what is bleeding it to death, and most of it would be the display....
Though, vivid seem to have a smaller battery compared to other phones of similar functions and/or size, so that might be the reason I am not really seeing a very good battery life?

My solution was to get a larger battery (2100mAh, the largest one with stock format) and using juice defender to control my Data Connection. I am getting about 60% more using time on a normal usage whan before!

I actually have both Motorola Atrix 2 and HTC Vivid. However, my Atrix 2 would last about two days between charges, which is kind of weird. I have my personal account and company account on that phone (personal is to activate the google stuff), so it eats up data twice as fast, yet it is almost twice as long battery life.
And to update a little bit from my post before, it seems I am getting better battery life now, after 4-5 days of flashing the new ROM, let's hope it is true....or I am just going to go hunt for a bigger battery

Actually, the Samsung Galaxy Note is way bigger than either Atrix or Vivid, so with a bigger body, I would assume that a bigger battery is possible. But if you look at current phones, I rarely see batteries that are above, say, 1800mAh, let alone 2000mAh and above, stock of course.

Could you share the details on the battery?

Andida batteies are easily found on Ebay, but beware of Chinese fakes!! I got mine from a seller in Canada, all good.

'How To Get Better Battery Life' tips and tricks

I haven't seen one of these threads yet, and I think it will benefit users of our D4 forum.
If you have any tips/tricks, feel free to add them here.
My first tip: TURN OFF 4G AT ANY TIME POSSIBLE. 4g is a battery vacuum.

Here's the biggest....Widgets and Social Networks.
Watch your widgets (weather, news, facebook, etc..) that update/refresh. Most will allow you to adjust the refresh time. Set it high or to manual refresh.
Social Networks.....set them to refresh only. You don't need them refreshing their data in the background, just have them pull the latest down when you are actually using them (Facebook, Twitter, Google +, etc..). Set to manual refresh so that they only refresh when you are using the app. You don't need the latest status messages your friends are posting hitting your phone when it's in your pocket.
WiFi and. 3G/4G.....if you are in a location that makes your phone drop/search for signal and WiFi is available....use WiFi. The constant searching/seeking and establishing a 3G/4G network connection will kill your battery faster than having a constant 4G connection. This leaves the cellular band free for calls and all your apps that sync/pull data from the internet can happily run over the WiFi connection instead of killing your battery.

I second this, keep your widgest, number of home screens, and social networking apps down. Phones haven't reached the point of being able to be computers quite yet. Here are some apps to keep it snappy though:
Fast Reboot (by Great Bytes Software)- same as a battery pull without having to. Clears up a lot of RAM.
Lte On/Off - with this, you can switch to 3G (CDMA) only, and have it set to automatically default to that setting in the case of you switching to airplane mode for some reason. But it does reset the app if you turn of your phone. Fast Reboot doesn't clash with this app.
App Cache Cleaner - clears out a lot of the cache you otherwise would have to go to Manage Applications to clean out.
That's all I can think of at the moment for non-rooted users. I won't go into rooted b/c this is not the right place. But here are a few battery saving settings:
GPS - have only the Google one on, it's the fastest in my experience.
Display - have it set to the lowest setting when at all possible. Only lowers color distortion in my experience.
Developer optionss - go in here and turn on the force GPU settings. This may not be the case with everyone, but it gives my phone a little more zip and makes things smoother.
Apps (this is the very bottom of the developer settings) - Adjust these to your liking. Perhaps try setting the max number of backgrounded processes to 4.

I wonder how it looks on you ...
on my droid 4 and with Jelly Bean i lost ~5,5% battery by hour no matter what i do even on airplane mode.. still aroud 5% by 1h
please can you advice how its look from your side ?

I had the same thing with my Droid 4. I finally sbf'd it, and reinstalled everything one at a time. This fixed it.

Is there any way for the Droid to use only 2G networks? 3G/4G while idle seems to be the biggest battery drainer.

Same here. In a couple cases its just made it worse. I will be trying out the extended battery in a couple weeks though. Hopefully it'll let me go at least a day without charging.

Making it better
The Droid 4 firmware just isn't very battery friendly... and it's not a new phone so your battery probably isn't either. Two things to consider.
LiIon batteries lose capacity over both cycles (cycling losses) and time (calendar losses.) If your battery is 18 months old and was charged nightly, you've lost 25% or more of the life anyhow... much more if the phone was kept plugged in after the charge and ran warm. And the drop accelerates with more cycles. It may be time to change the battery.
Adding JuiceDefender ( I use Ultimate) triples my battery life even in basic mode.
Replacing the battery is really simple; buy one from Amazon, open the back, carefully pry out the old one (it's held down by a double-sided tape), unscrew the connector (very small Torx, but jewelers screwdrivers work), swap and reassemble. $30 later (and a few hours to charge), you have your capacity back.

yeah after trying juice defender for about a month or so i noticed my phones battery life extend much more. so i opted to buy the ultimate juice defender and sure enuff more battery life... i am very pleased with this app. however if in the future i do want to extend the battery a lil more, then i will purchase a brand new battery and then replace the old one...

Turning off auto sync, turning off WiFi while on 4G works. Also make sure there's not any apps running in the background. Being root, there's apps you can download to close any open app

What I meant was if it was possible to just use 2G for Internet connections, instead of 2G+3G+4G.

with CM it is an easy to safe much energy! and if you really want to do this on a right way, you really need to own a rooted system....
1. underclocked my cpu for 200mhz, dont have to comment.... if you use lightweight lounchers and care for background apps, it will noprob
2. use only 2g-networks, those are more available than every other networks, and even tcp/ip works with it, for whatsapp etc it is way enough bandwitch
very important!!!!
3. check your internal recievers after installing an app!! with "autorun manager" on a rooted device you can uncheck every function from every app, even autostart of an already killed facebook app, or statistical functions from apps which comes with most of them
4. get your brightness automated, if it is dark, you can automatically safe energy by a automatically regulation
5. maybe you would prefer to deactivate vibrations/haptic feedback/call vibration completely, its very energy consumpting.....
6. deactivate the gps-reciever complete, and just turn it on if you need it
7. set your display timeout as less than possible for your behaviour, 15 seconds may be enough
8. know what runs in background, evrything in background, sucks energy.....
9. deactivate nfc
10. deactivate bluetooth
with this i get a standby about ~1-3 days! and if im phoning and writing to much maybe not fully to one day. if i watch now on my energy tables, my display is consumpting still 40-60% battery per charge, but i dont think that even more safings would be possible
and with the app "tasker" you can even script this in endless environments

How does JuiceDefender save the battery? I have used many battery saver apps (including Juicedefender) and I always find that they run in the background and kill the apps which I would close anyway. Does it do anything besides kill background apps? By now I've deleted most background apps and have only kept the apps I want (which are few) and I still find battery life subpar.
Also definitely keeping 3G/4G off is a huge help. Wouldn't be able to make it very far without turning those off

I use Autorun Manager pro to freeze Google Play Services. Funnily enough, Play Store and Google Maps still work like a charm yet Google Play Services don't run background
Edited: With stock rom, install SetCPU and change the governor to hotplug. Underclock max frequency down to 800 MHz. You won't notice much different for normal tasks like watching videos, sms,...That setting is enough for me to play FF4 on MyBoy but playing heavy graphic games might not be snappy tho.

For me not using gaaps improve battery life. Every one knows for google play service that you cannot stop Instead I use calldav for my contacts.

me battery drain in me droid 4 jb 4.1.2 with gsm patch is of 60% for screen, the battery only run about 6hs, can i fix this? thanks
