Battery saver - myTouch 4G Q&A, Help & Troubleshooting

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].

[Q] I get about 4 hours of usage out of a full charge - how about you?

I have been on here a couple of times complaining about my lousy battery. Well, today I decided to see exactly how far I can take this thing before it conks out on me. Here are my results.
The phone up-time was just over 19 hours, with 14% battery left. (I took my results at 14% because I didn't want the phone turning off on me thus losing all data.) About 49% of the battery was used by the screen, which was on for a total of 3 hours and 20 minutes during this 19 hour period. The rest was split up among other activities, but the most notable/concerning area is 43 seconds of voice took up almost 2% of total battery usage.
I could probably pull out another half-hour or so usage before the phone's battery totally dies, so my final number is 4 hours of usage out of a full charge. This is total usage, i.e. the screen was on for 4 hours.
The phone was at lowest brightness all day except for 10-15 minutes where I had it on full 'cause I was using it outside. I am not using any CPU throttling apps, or such. Background is not fully black. I use one widget, rest are icons. I have Advanced Task Killer which I routinely use to kill tasks, but to be completely honest, unless there is a rouge task ATK does not increase battery life by much. Phone was on 3G primarily, although there were times during the day when I was on EDGE because of weak signal.
All in all, the battery on the Vibrant is pathetic for what it has (Super AMOLED, 45 nm, etc.) but I am glad I can at least last a day. Hopefully Samsung has addressed battery issues in Froyo.
Feel free to post your results on how long you can make your battery last below, so we can all get a better idea. Please do not post "my battery lasts XX days" - give details on your usage, like how I mentioned the battery was at 14% after 19 hours up-time, but actual usage was 3 hours and 20 minutes. Often times it seems like many people brag about how "great" their Vibrant's battery is, but really they rarely use the phone all day hence the "great" battery life.
I completely feel your pain. I had the same issues with my vibrant also. I personally do not believe it is the battery any more because after I applied the ryanza one click lag fix my battery life practically tripled. I kept a very close eye on my usage and settings for the first few weeks. I would get about 12 hours out of a full charge and I would barely use the phone. Frustrated me to no end because I would hear people say that 12 hours with a powerful phone like vibrant is expected. To me it was not acceptable.
I never changed any settings or installed any programs after doing the lag fix but it certainly had a drastic effect. Ill get more statistics when I get home, im at work right now.

I got a good deal on eBay for a 2batteries and a charger for 10 bucks . . Go find out. And about the battery I get around 3/4 day of pretty heavy use, wifi on all day and such.

get Juice Defender if you want to squeeze even more out of it
but having the display on almost 4 hours....that's gonna suck the battery no matter what phone you have
mine has superb battery life. I am always confident it will get me pass the day and more. obviously, if I game and web a lot, it will drain faster. For my typical day, it's perfect. I went on to over 2 days with this charge. What an awesome battery!
I get about 5 hours of usage. On wifi it goes up a like a hour .

Have to agree with this. I tried it out and got quite a boost. I didn't keep as good of details as the OP on my battery use but prior to juice defender a was struggling to make a day. Now a day is not a problem. My typical usage is probably pretty high, lots of internet, lots of tinkering right now plus working on morphs and things, I do keep my screen all the way down except when outside (rarely use my phone outdoors so not much of that), no widgets, no task killer. When I installed juice defender I used the stock settings with the exception of allowing gmail and chat to sync anytime. Juice defender says I'm getting an average of 1.7x the battery life. I think almost all of that comes from when the phone is asleep.
Edit. Checked on details.
Pulled my phone off the charger at 6 am it was at 100%. Used to to do some reading on my way to work (about 30min on the train) worked on some morphs, checked some emails, downloaded some stuff. I'm at 82% and it's 12:20.
Cell standby 39%
Display 33%
phone idle 23%
Various 5%
I use my phone for quite a bit during the day and pull about 13 hours before it starts blinking at me. I personally have zero problems with that amount of battery life from a device of such caliber. My best friend was complaining about her battery in her Vibrant and like I tell everyone else, it's probably some rogue app somewhere. She didn't believe me so we swapped batteries 3 days ago and I still get the same usage times out of her battery as I did mine and her battery life has improved significantly as well.
I don't know what is is that people are doing to get 4-5 hours but 13+ with average use (text, moderate browsing, syncing all day, screen at full brightness all day) is to be expected with this phone. I will post a screenshot of consistency over the course of this weekend to visualize my point.
Also I do not use a task killer of any kind except the Android built in one and I removed hers as well

You mean if you actually use the phone it will drain a lot faster. Your post is a perfect example of what I mean when I said people post very misleading results. For those ~40 hours that your Vibrant has been up, your display has only been on 1, maybe 2 hours (hence only 8% battery usage). Your result is not accurate at all - you aren't using the phone. Anyone can get great battery by letting it sits for hours on in.

Thanks I will look at Juice Defender, but I am not too sure what it will do to help improve my battery which I am not doing already. (I leave GPS off, WiFi off when im not using, have applied lagfix, etc.)
The Droid X is known to get 7-8 hours; and considering the Vibrant has power-friendly hardware, the Vibrant should be getting the same.

When you say 13+ hours, do you mean total up-time or total usage time? Because, as I mentioned in my post, my total up-time was ~19 hours, but usage was actually ~4.

I apologize for being unclear before. total usage time is about 6.5 hours of consistent usage. Such as watching movies, playing games, and browsing the web. I will post some battery usage screenshots a little later.

Thanks for clearing that up! Well, it sounds like you are fairing better than me, but without actual data it is hard to say.
Oh, and an FYI: I just called up T-Mobile and had them send me a new battery. FWIW, I am not being charged anything (not even shipping) and I don't have to send back my current battery. I love the retention department .
Can someone post up what they do/what settings they use for juice defender? I installed it but I really don't see how it could save me any more battery seeing that I keep wifi, gps, and all that off, plus my screen is on the lowest setting at all times
Hi all,
What I found out that works best for me is, no task killer, no juice defender, lowest display setting possible, and turning off 3g. 3g ready drains the battery. Task killers are pretty worthless. Do some research on that topic. Android kills programs all by itself. And task killers run in the background, using up battery. My phone is rooted, so I run autostarts to control what starts at boot. My uptime isn't great, but its adequate enough to last from morning to night. I do agee that the battery life when using the phone itself for voice calls is sub part at best. I do believe froyo will help with a lot of these problems. Just my 2ยข.

DON'T use task killer. Vibrant has really good system resource management. With task killers constantly killing core system processes, the phone has to use more power to keep restarting them.
You can read more about it here: http://geekfor.me/faq/you-shouldnt-be-using-a-task-killer-with-android/
And only turn on active sync for apps that you absolutely need to have them syncing all the time.
This should make your phone last for a whole day with decent usage. If you are still getting very short up time, you probably have a bad battery. Call T-Mo and ask for a replacement.
It all depends on usage. The first days when I got my Vibrant, I was downloading apps all day, or browsing websites, so the battery barely lasts for a day. I usually leave my phone plugged in to my laptop when going to sleep, and set the laptop to auto-shutdown in 4 hour, so the phone gets unplugged at about 4:30 am. With that heavy usage, I needed to recharge at about 7 pm.
However, now that I'm not playing with it that much, the battery life improves greatly. Now I usually do 10-20 text messages and about 30 minutes voice call everyday, also some browsing on the xda forum, and maybe reply several emails. The battery is usually at 40 percent at 10 pm. The only thing I can complain about is that with 40% battery left, I don't want to do a complete recharge, but it won't last the second day either.

I forgot to take pics lol. (busy with my fantasy draft). I will take some today. Rebooting my phone right before I leave for work and some throughout the day.
It still will be hard to say why my battery life exceeds yours but you will at least be able to compare the two.

Battery Life?

What kind of battery life are you all having with HTC aria? I might switch to it but want to know exactly how the battery life is with heavy usage of calls and web?
Running cm6 and I usually have at least 50% left after a full day. Way better than my iphone 3gs that would be dead by now
Sent from my Liberty using XDA App
Battery life is a point of contention for a lot of Android users I know, both advanced and casual. With a typical day of use on my Aria (running CM6), I'm down to around 40 percent by the end of my work day, then have to plug in my car charger during my commute to juice up for the evening. Moving from a BlackBerry Bold 9700 required some adjustment, because that device can go 2-3 of similar usage without requiring a charge.
All depends what you're running... Don't run stuff in the background that prevents idle state and it's all good

This!
With any Android device, you need to pay attention to whether any applications are preventing the phone from properly sleeping when idle. For example, I found out that the Slacker app would stay running in the background despite telling it to quit (from the program's menu), and it was keeping my phone awake. If I force closed the application, my battery life increased significantly. I'm sure there are other apps out there that have the same problems.
I can say with my current setup (CM6 with only Google apps syncing data, no Twitter/Facebook/etc. allowed to sync in background, wifi and bluetooth disabled), I will be at ~60% battery after 24 hours of standby. But that's a pretty extreme case and most people probably wouldn't get that sort of battery life with normal usage.
I'm running liberated rom and can get 2 days on a charge with light usage. More than 1 full day with medium to heavy usage.
Very happy with the battery life from this device.

Suggested setup for amazing battery life

hi guys/girls,
i wasn't able to find any sort of thread pertaining to what setup everyone is running for the best/worst battery longevity so i figured i'd at least post up how i have my phone setup in order to pull off a full workday/night and about lunch/dinner time til i have to absolutely recharge my phone (30-35hrs max). maybe if it helps someone get the most out of there battery between charges then great. so here we go...
how i use phone:5-10 incoming emails daily (hotmail/aol)
200ish texts/day (incoming/outgoing combined)
1-2 hrs or so internet browsing/zooming in out
1 hour talktime daily
listen to 3-4 hrs of music on sd card at work
signal strength 3-6 bars at all times
what i have running/not running:
gps off
wifi off
network on
1 min backlight on
full animation on
auto brightness on
vibrate/sound on for calls and notifications on
volumes for sounds set to 3/4 or so
no task killer installed
facebook/friend stream off
weather sync on
google sync on
news sync off
stocks sync off
foursquare on
i personally charge off a usb off of my computer when phone hits about 5% or so. so maybe that is charging it slower and not wearing out the battery cell? i've read that the slower the charge on a battery the better, correct me if i'm wrong. my phone has had no adverse effects and has not bogged down once. i hope maybe this will help in some way to narrow down what may be causing some users phones to die faster.
maybe have others post their setups to see a trend would that help?
I pretty much have gps, wifi/4g always on if I'm at school or home, and auto sync and I get 10-14 hrs. Yesterday I went from 8am to 1am and battery was around 55 percent but I didn't use my phone like I usually do. Regular usage usually nets me about 10% an hour.
Each day I probably send around 200 texts, read forums, google reader, and pulse in total of about 3 hours and play about an hour or two of games.
I use to use juice defender app but I did some testing over a week and it doesn't help at all imo.

most battery monitors or battery saving apps actually have the opposite effect, especially the battery monitors. They're using power to monitor the battery condition, so they tend to do more harm than good.
Yea o was using a battery widget for a week or so and it seemed like it used more battery than it was worth. I try to run my phones as lean as possible and only use what I need when I need it.

Seriously?!
As far as I'm concerned thats borderline amazing. How in the h-e-double hockey sticks are you guys getting such great battery life? My phone doesnt hit that and all I really do is IM and browse the web maybe a combined total of 5 hours a day and thats pushing it.
01/27 update...another update if anyone is keeping track...pulled phone off charger at 8am now its 11:30p (16 hrs+/-)..45-50% battery left...also realized i left gps on with navigation running for 2 hrs from lunch earlier in the evening and prolly sent out 50 texts in last few hrs since last battery status update and looked at pics with a co-worker...so yea so far the setup above is bringing some good results for me.
01/28 update...its 2pm (30 hrs later), and phone just beeped at 15% battery left. finally ut it back on charger so i have a full battery for work. so there you have it folks. pretty nice battery life if you ask me...been texting and calling for the last 2-3 hrs today too which triggered the battery beep.

try recalibrating the battery...basically let it die all the way to the point where it wont even turn on anymore...then I like to remove the battery for like 30 secs or so but im not sure if its actually necessary...then plug it back in and let it charge all the way til the led turns green...then take it off the charger and turn it on....did that and i noticed a big difference especially after a day or two

Battery Life?

Is anyone else having issues with battery life? My wife reported that she was at 70% when she went to take a nap and when she woke up (around an hour later) it was at 30%. I don't have it with me so I can't look up battery stats but I know wifi was off. Even if GPS was still on, you'd think that 40% of a giant battery wouldn't go by in an hour.
I just want to see if its worth investigating as faulty hardware or if there is a software issue involved. She did have meebo running which is a battery drain but even on my captivate with trillian running I don't lose battery like that!
Mine has been absolutely disappointing to say the least. Seems to last less time than my N1.
MILES worse than my iPhone 4.
Is meebo a instant messaging app? A lot of them aren't coded very well and constantly use data therefore killing the battery terribly. I've had my phone on wifi all day since 8am and i'm still at 70%
2.2 isnt designed to take advantage of 2 cores. Therefore its probably horribly optimized. 2.3 if it gets around soon - should be far better.
My battery life is great here.... no complains havent charge my phone since last night at 6pm... i still have 40% left

so far my battery lasts about 20 hours.
I turn off blue-tooth
turn off GPS, wireless is only on when I am near wireless spots
Normal day yesturday:
60 minutes playing WSOP game
40 minutes cell calls
40 texts messages
30 emails
40 minutes playing with settings exploring the phone...
look at whats sucking up your battering in the battery manager, then take adequate measures to fix the battery hogs. My battery gives me more than a full day of play and talk
mine's been off a charger for about 8.5 hours, and it's down to 20%. But it has been streaming pandora continuously for about 6 of those hours, so i'd say i'm doing pretty good. Mix in an odd phone call, playing, downloading apps, setting stuff back up, etc, and i'm not at all unhappy with battery so far.

Stop spreading misinformation.
The kernel (which handles all low-level I/O on the device) is compiled for multiple cores (hence the SMP tag, which stands for symmetrical multiprocessing, under About Phone, under Kernel Version).
On top of that, the Android SDK supports threads, which is in turn supported by the kernel and therefore spread across cores.
I'm suspicious that Motorola is using a bugged battery level scheme or calibration. I ran the battery down from 100% to 5% yesterday. When I got the 5% alert, it was still going strong afterwards for 30 minutes of continual use (downloading apps over wifi and configuring them, browsing the web, etc) after. I eventually got too tired to keep going and see how much longer it'd last.
Does the atrix have better battery life then a captivate?
Of the charger at 7am, its now 2:42pm and im at 80%. I use the phone heavily but auto sync is off.

meebo is awful, awful, awful at battery drain. Utterly awful. It uses a fairly inefficient way of checking for new messages and it kills battery life. Do not use it.
My Atrix battery life has been great so far.

cool, thanks for the info! I've never used it before I just use trillian but its what she downloaded.
My battery life is impressive. Yesterday off of the charger at 10am and I didn't charge overnight. When I woke up today it was still at 40%. I did a ton of downloading apps, setup, playing games and web browsing including flash videos. I played a 14 track cd from it when I went to bed, but I had it in airplane mode while sleeping. I use the apps for FB and Twitter instead of having Motoblur do everything. My brightness is over 3/4 too so I'm not handicapping the device for battery.
Hmm interesting..i have been getting HORRIBLE battery life. Off charger at 7am, by 12 i was at 20%. Some background data but ive tried to limit all refreshing apps to once a hour.
ok I don't know how to check useage by app but...
under "battery manager" I can get to a screen that looks like my captivate battery useage screen.
unplugged at 70%, useage is as follows...
time since last unplugged:3h 27m
Display: 50% Time On: 30 mins
Phone Idle: 36% Time on: 2 hours 54 mins
Cell Standby: 16% Time on 3 hr 23mins
Currently sitting at 30%
I took mine off the charger at 7 this morning. After very heavy use, and auto sync with facebook and gmail on. I'm at 30%
By heavy use I mean downloading apps, emailing, texting, gtalk all day.
I would say it's pretty good. Much better then my nexus one.

i expected it to be very good, its huge! The whole reason i'm posting this is to see if there is something wrong with her battery. The screen is usually the biggest battery drain on my phone (samsung captivate) but hers was only on 20 mins.
From my battery manager:
1d 3h 26m 13s since unplugged
That is 27.5 hours, including a whole day of heavy use. I'm at 15% battery.
This phone kicks ass.

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?

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.
Sent from my T-Mobile G2
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.
