Battery saver

Can anyone recommenda good battery saver app? I tried JD (Juice Defender) but it basically kills my data and sync to my exchange.
Thanks in advance

which rom are you using? I'm currently getting around 50 hours plus, off a full charger with moderate use to heavy use. Mainly emails, calls and data usage, running cm7. Yesterday phone was off charger from about 6am, still off charger and I'm at 85% as of 9am, 27 hours and counting.

How the hell did you achieve this?
I'm lucky if I can get about 14 hours on CM7 Public Release with moderate to heavy usage... Wow.
On Iced Glaicer I get about 8-10 hours with moderate to heavy usage.

Battery life is all relative. Every single person will experience different battery life. The apps you have installed, the amount of time you spend on it and the time you spend on/in each app, distance from cell towers, distance from Wi-Fi sources, settings you have for every app and things like sync and what not.
The best battery saver is YOU. Everything depends on how YOU have your settings. Everything from screen timeout to sync duration.
There are no real software apps that will help your battery except setCPU which can over/underclock your cpu thus saving your battery. Any other software that runs in the background to "save" battery is only using it [and therefore draining it].

Battery Tips?

I just want to know what I can do to improve my battery on CM7 nightly 32. I'm at 21 hours now and almost dead. Yet I see people get stuff like 2 days and 10 hours... I have tasker and the only profile I have is when the screen goes off it turns mobile data off (not sure If it works so I also use apndroid). I NEVER use wifi, bluetooth, or high brightness. I do however have gps on so in case I lose my phone is lost or stolen I can track it. So there's no way I'm disabling that. I have tried juice defender but figured since it can't effectively disable data for 2.3.3 I saw no point in the app. Any tips?

Sorry for the typos, I'm half asleep and there's no editing option in the xda app... atleast add it to the premium version!

21 hours on moderate use is great battery life. 12 hours is usually the measuring stick for smartphones, less is bad, greater is good.
Don't know who you saw getting two days plus, but they are either not touching their phone or have an extended battery.

Best way to extend battery life is to get an extended or high capacity battery. I just got the Mugen Power pack, not the chunky one, and im in the process of breaking it in.
On my stock battery i was getting about 17hrs of moderate use. Almost no talk but alot of texting, engadget and youtube mostly on wifi with gps always on. That might give you an idea, plus, there are countless battery related threads on here.
Will post back in afew days after my Mugen has cycled afew times.

I have 4 stock replacement batterys and never plug my phone in to the charger. When my phone is at about 5% i just take one out and pop the next one in and charge them in the wall... I know its not the answer you want but I never have a problem with battery life lol

I would agree that 21 hours is great battery life on this phone. I can get a week of battery life on my phone if I put it in airplane mode and stick it in my desk drawer =P
Not sure how big of an impact the tasker profile has. Unless your screen is off for long periods of time I would think that it might harm the battery life because every time you touch the device, it has to 'search' and connect to the tower again.
You can try running the phone at the stock CPU speed to see if that has an improvement on your battery life. I currently run the same 1017/245 as you with a screen off profile set at 245/245.
For me, as long as I can make it through a day's use, the battery life is fine. With moderate use I can go about 15-18 hours and heavy use I'm at around 12. The car charger in those cases is a life saver.
Bottom line is, battery life really depends on your usage habits. Those people getting days out of their phones likely aren't using them very much...

well i have setcpu set at 806 max and 245 min. screen off is at 245/245 and on powersave governor. other then that its on ondemand. i also have profile set to reduce the CPU based on battery. I have it set to <101% its at 806/245 , <41% its at 768/245 and less then 25 is 368/245. i realize that these are low speed but i hardly ever get lag and i use it for everything, music, video, youtube, internet, twitter, facebook, xda , and a here and there gmail. i guess if im getting exceptional battery life... anyone want some tips?

I find the more variation I put into profiles on setcpu, the worse my battery life gets. Theory - it is constantly watching and making changes based on your CPU needs and battery. So I have mine set to 1113-1113 performance, 245-245 powersave screen off, 245-245 powersave 45degrees+ and for your mobile data, try just having a widget to turn it on and off as you need it. You probably don't need it on everytime you turn on your screen do you?

The apndroid widget eventually gets out of sync with on/off with the data... I think its gingerbread. Most apps can't effectively turn the radio off. I hope they make one soon!

I find the stock battery to be not that great. I bought the Chichi batteries way back in October (when they were still considered cheap) and theyve been great. I havent really done any new tests since October, but back then (before I had a data plan) I was getting atleast a day and more (from 100% to dead) with moderate usage.
I'd look for a high capacity battery, though they seem to be expensive now.

The power bar widget that comes with cm7 works perfect for me. Turns onoff Wi-Fi/apn/GPS/brightness/airplanemode

I just tested out my battery the other day. I got a day and 13 hours and I was at 19 percent. Wifi is a big battery killer, and brightness is too.

Ill post a battery success story...sounds nerdy lol. And i live at my own home with my own family lol.
My mothers g2 is rooted and running cm7 nightly 29 or 30, I installed it last week. I asked her today for the first time how the battery was after a week. She is using an aftermarket 1800mah battery, wifi only at home, she was almost at 32 hours and had 39% battery left!!!!
Not sure of all settings but i put it on 1113mhz, on demand with min 368, autobacklight, wifi only at home, bluetooth is always connected and on. Talk is about 70% of her usage overall. 4 gmail accounts. I did not install set cpu at all. I even stopped it on my phone because it didnt help me one bit.
Not too shabby. I was at 57% with some texting but a lot of gps usage for latitude and wifi always on even when not at home.

here is what i get out of a day (battery consumption for specific tasks are mentioned in percentages measured using juiceplotter)
wifi on constantly
display set to 24% brightness
background sync enabled (google, weather 6hrs, whatsapp and facebook once a day)
45 min video (rockplayer no h/w decoding) 15%
1 hr browsing+chat 15%
30 min calls 6%
20 min music+chat 5%
20 min general usage 5%
1 hr flash streaming 15%
24 hrs standby 24% (@ 1% for every hr of standby)
15% battery remaining after 24 hrs i.e. low battery warning.
i disabled the use wireless network option under locations and always on mobile data
and get much better battery life, also i use wifi constantly when available (which is 90% of the time), it is much better for battery life than using 3g or gprs/edge.
pretty amazing battery life IMO i am very happy.

So i have cycled my Mugen 1800mA battery acouple times. on average, i'm able to get about 27hrs of heavy use. Here are some settings as a baseline:
Always on Data
Wifi always on
Auto brightness
1GHz clock speed
massive amounts of text use
massive amounts of screen on time
will report back in afew days time after some more cycles.

Android OS at 52% and battery lasting 5 hours help..

I had problems with my battery, but since I rooted the phone I think that it is getting worse. I am not sure if it is the rooting, but now I am getting Android OS at 52% and the battery barely makes 5 hours. I am a using the phone, but it should last at least 10 hours. I did root the phone in order to delete batterystats.bin but this did not help at all. I used Battery Calibrator, also deleted the batterystats.bin from the Android Terminal followed the procedures of charging the phone to 100% waited until it says full calibrated the battery or delete the batterystats.bin discharge the battery until the phone dies and charged it to 100% again....but still the same thing. I guess the Android OS is killing it. Any suggestions will be greatly appreciated. Thank to all of you in advance!

52% is high, but that also depends on what other tasks you are doing at the same time.
You should have 5 hours of Screen On time if not more, thats what you need to check, not some hours.
Regards.

5 Hours screen on time? I'd love to get that lol. 3 Hours 50 Minutes is about the best i've got, but then that is while battering the net and the camera.
Get around 1 to 2 days battery life though although I am a light-medium user.

Install the free version of Wachdog , and see if it can identify what apps or processes are eating up your battery.

Look here:
http://forum.xda-developers.com/showthread.php?t=1230140

So to make it clear. My battery lasts about 5 hours. I do not think this is screen time. This is the total time of the battery. I have at battery use
Android OS 52%
Display 13%
Android System 10%
Email 9%
Cell Standby 4%
Voice Calls 4%
Phone Idle 3%
Maps 2%
I think before the rooting I had Android at around 12-13% and the highest was the display. I keep the display close to maximum brightness, but it counts only for 13% at the moment and it was around 40% before rooting. Do you think resetting the phone could solve the problem?

I will again, and post the reading. Is there anything particular that I have to watch?

That stat you have given is after how many hours of usage?
Besides, what kernel did you use for rooting?
Install 'Better Battery Stats' and see whats going on in background.
And do turn off Wifi, GPS, 3G, Packet Data, Auto sync, Background Data, any running widgets when you don't need them. And also check if you have push-pull Exchange.

I got CF-Root SGS2_XX_OXA_KG5-v4.1-CWM4.zip I have after rooting Kernel 2.6.35.7-I9100XXKG5-CL420550 [email protected] #2. I think it was absolutly the same before rooting
On the battery usage it says 13H 23M but It was overnight and now I am charging the phone. Overnight the battery went down around 50-55% without usage. Yes I have WiFi and Bluetooth on all the time, and I am using 3G all the time when I am out of the house. Also I have a lot of auto sync and exchange, but because of this I bought this phone. I will get this app and see the results. With Watchdog Lite I get
9.9% CPU in background Android Apps

Turn off wifi. You router is obviously one of the ones that are not compatible with SGS2.

I have Belkin N750 DB, and It was OK before. When I turn off wifi and restart the phone Android OS is still at 52%. Also I have no problem with my Galaxy Tab 10.1 on the same router. But thank you very much for the suggestion.

If you have wifi and bluetooth on constantly also 3g , you are really taxing the battery 5-6 hours is about right.

I am keeping the bluetooth on so it can connect to my car hands free. I will turn off the wifi and I will try to see what I will get.

I had simillar problems. High os usage and short battery life.
Used better battery stats overnight with everything data related turned off and fully charged phone. turned out that my facebook app was keeping the phone awake in standby and killing the battery. Lost 55% in 6 hours. Removed fb app and battery life is mutch better. Went from 8 hours with about 1 and half hours screen time to 14 to 16 hours with 3 to 4 hours of screen time on one charge. Os usage is now between 20 and 35%. Use to be at 50 to 60%.
This is with stock kernel with wifi and 3g allways on with some autosync and push mail allways on.

You just need to tap on Display under battery usage graph in settings.
Also FB doesn't stay awake in background if you Exit it. So think before you remove it, if it's needed to be removed or not.
Regards.

Where you check your battery usage you can select the various entrys to see a detail summary and see what they did.

Since the phone was charged it is 1H 32M 16S. I am at 88% of the battery and 9m 3s on Display time. I do not have the bluetooth on, the gps is off Facebook app is removed. The only think that I gained is instead of Android OS at 52% I have it now at 48%
I rooted with KG5. If I try to root with KG6 do you think this might solve the problem? My stock was KG5 on a phone from Expansys USA Polish model.

[Q] Battery only getting around 6.3hr of total screen time?

Hello my battery is only getting around 6.3 hrs of screen time total. I have read many threads about the battery time and a lot of ppl are getting 8-9 hrs of screen time. I have several questions.
1) I have only charged it 2x, I read that the battery life will get better after a couple of more charges. Is that true?
2) Ppl say it will get better after a couple of cycles, do they mean letting the battery run to 0% and then charge it all the way back to 100%?
3) I also read that I shouldn't charge to 100% every time , is this true?
4) Should I leave it on when charging?
My brightness is only set to 40%. My screen uses 65% android sys uses 9% and chrome uses 8% of the battery
Any advice to increase battery life is appreciated.
Sorry if the questions are repetitive, there are a lot of contradictory info, it is getting confusing.

Get a battery monitoring app & find out what's using most of the power. I use GSam Battery Monitor, and Better Battery Stats if your rooted. It will break everything down for you. The "app sucker" section within it tells you what % of power each app is using. Turn them off! Maps is usually always reporting your location, so turn off location service.
Your device has a Lithium-ion battery so no need to cycle it. Google: li-ion maintenance. I plug my devices in every time I see a micro-usb! Cycling refers to older ni-cad batteries.

[Q] Checking wakelocks without root

I've been having some massive battery issues the past week, with a full charge going dead after only 8 or so hours of medium to low usage. I thought it was maybe the battery, so I bought a new one, but it's still doing it. GSAM shows "Android System" taking up the most battery by far (close to 28%), but I have no idea how to narrow that down to specifics. And after I updated the last OTA, I lost root, so Wakelock Detector isn't working anymore. What's the best way to figure out what's causing this? It's super annoying.

Hey again I posted in another topic of yours I would use any app I could I've used battery doctor that monitors apps. Deep sleep battery saver. Seems like your phones awake all the time. Maybe even battery monitor widget.
