How I nearly tripled my battery life!

If you just wanna see my tips then skip over the next few paragraphs lol!
Hi! I am not sure if this exactly has been posted already, or if it's common knowledge and I am just slow lol, but the last couple days I found out how to maximize the battery life on my phone by (imho) a huge amount. And I wanted to share with the community.
So before I did this, I'd generally get maybe six to eight hours of uptime before the battery was critically low. This was really frustrating because by the time I got home from work my phone would be almost dead. So I'd charge it in my car for a little bit, but then when I went out I'd have to turn off Wifi, GPS, Bluetooth, brightness all the way down etc. just to have enough battery to survive the night.
But now I managed to get 18-24 hours out of a single charge, without having to manually touch the settings too too much (GPS/Bluetooth when I need them.) Now I think a lot of this depends on your personal usage, but for me this worked great. And here is how I did it:
1. Disabling/making less frequent updates in apps. For me this was Twidroid, Facebook, and NewsRob. I realized that I keep notifications off for these apps (I don't need to see a notification everytime someone I follow tweets you know?) and that even when they were all set to auto-refresh every 30 minutes or whatever, I STILL always hit refresh when I went in anyway. So I disable automatic updating. Obviously this depends on your usage, but for me, I didn't need up to the minute social networking information, and manually refresh anyway. But I went through all my apps that updated automatically and changed the setting.
2. Task Killing. In a perfect world, Android would efficiently manage it's own app load, but unfortunately the world isn't perfect. I found that if I know I'm going to be putting my phone down for a while, take a second and kill all the runnings apps. I use Astro, but there are countless apps that can do this for you. This is something I don't do frequently, but for example, if I'm going to go to bed and I don't have my charger, but want my phone on in case of an emergency, I'll kill all the running apps.
3. Brightness. After weeks of changing it back and forth because I don't really love the way it auto adjusts, I just said f**k it and put in auto. While sometimes the level of brightness it selects seems a little whack, it's definitely saved battery life. And saves me the trouble of changing it myself. I also found that setting the timeout to 15 seconds seemed to improve battery life.
4. Juice Defender. You can find this app on the marketplace. It has two modes, easy and advanced. If you want, you can go into the advanced and set schedules and all kinds of stuff. But for me, I just went into easy and hit enable. From what I understand, what this does is that if the screen is off, it disables network access for 14 minutes, turns it back on for 1, then off again for 14 etc. So, something like Gmail which is push will only be able to access the network every 15 minutes. Unless you are on WiFi. Now, if you NEED push e-mail and don't have WiFi, this isn't a very good solution. But according the stats in the app itself this has given me a 99% increase in battery life, and I believe it.
5. The trackball. This is perhaps the weirdest of my findings. The trackball light apparently can DESTROY the battery life. The other morning at around 80% I let my alarm on the phone go off and didn't stop it, so the trackball was flashing really fast. Without a couple hours the phone was completely dead. Nuts right? So I found that if I disable the trackball light when I know that I won't be able to dismiss my notifications quickly (like in a meeting or sleeping or whatnot) I'm able to avoid this happening.
6. GPS/Bluetooth. Again, this might seem very case specific, but I use bluetooth ONLY with my rokr headset when I'm on campus at night, and I use GPS only for navigation. So I keep the off when I'm not using them. With the power strip widget this isn't very difficult.
Anyway, that's it really. Like I said, maybe this is all common knowledge and I am just stupid haha. But I figured if not, I was pretty thrilled to go from 6 hours to 24 hours without having to do too much. BTW, some weird things I found didn't have an effect as much as I thought they would - 2g/3g, I actually got MORE battery life when I had 3g enabled. And WiFi was the same way, even when I didn't have a wifi connection, the difference in life with having it on or off was negligible.
Anyway, I hope this is helpful! If I remember anything else I'll add it.

I really like this guide and I'm going to use it when I get my n1. I like all (and will try) of the steps except #5.. the trackball notifications is just too sweet to ever turn off imo. Thanks for the guide.

I'm really surprised to hear that your LED light in the trackball destroyed your battery life

I don't bother killing apps anymore. Since they're not in focus their not using the CPU so whats the point. (right?)
I dont have rubbish notifications on either, nor bluetooth/GPS unless needed. Ive got auto brightness on too.... might try juicedefender in future actually, it does sound good.
So what did you triple your battery life from anyway... 12 hours?

I was too but I duplicated that scenario a few times to make sure. Also, it might matter that I am running trackball succession and color hacks.

Trackball succession is killing your battery, not the trackball light.

48 is on the high side of things... I usually go to bed with about 40% remaining, and put it on the charger overnight... I get up at 8AM and go to bed around 12AM. So I am getting about 26 hours out of mine.
Edit:
Accidently typed in 36 when I meant to type 26. Fixed.

I have a noob question, which this forum is how I get most of my N1 knowledge...
Which uses up more battery life, 3G or wifi?
Thanks to whoever replies.. (my best guess would be 3G)

Which is still a lot. I'd really like to know how you are doing this. Do you make any voice calls? Do you text/e-mail a lot? Watch videos? Browse the web? Play music etc.?
I mean my usage is based on maybe an hour a day of talking on the phone, and a few hundred text messages, maybe a couple e-mails, frequent twitter/Facebook updates, and maybe a couple hours a day of playing games, watching videos, reading news etc.
I imagine if I just left the phone there it'd be close to 26-30 hours, but not with regular use.

Erm, this is not correct, is it?
The whole point of multitasking means things still carry on when not in focus. If you leave everything running, they will all try and use data and CPU cycles, no?

Some nice suggestions there c0wb0ycliche! Thanks.
A couple of other thoughts/suggestions...
1. In the choices of kernels, pershoots is regarded as being excellent with battery life (partly from being undervolted I imagine) and the fact it's also overclocked at the same time ain't so bad either.
2. Not sure how much extra juice is saved by not using a Live Wallpaper, but if we're talking about battery savings here it might as well be said.

I would not be surprised if a large majority of people who get 25+ hrs hook onto wifi networks for a majority of the data usage. When switching to wifi the phone steps down to 2g mode for phone services.

No. Some applications have sister services that do this, but not all applications.

Good point, has anyone mentioned SetCPU? If you set up a profile, it will lower your clock speed to 300mhz while the screen is off. Saves quite a bit of power.

Battery life improvment thread

One of the vital issues of the SE x10 is its battery life, i personally have to charge it once a day under normal use(10mins of browsing, messaging, phonecalls) while my older phones under heavy use lasted over 4 days.
Lets compile a list of remedies to improve battery life, every little bit helps.
Mine are:
Keep charger in my pocket
Close all apps before idleing the phone
Turn off everything wireless exept 2G
Prevent using the latest facebook app(Hogs the battery empty FAST)
I set the CPU's clock at 700/250mhz max min respectively
What are yours?

Use the phone as a phone. Don't carry around the charger, don't use any appkillers or CPU things, never ever turn off 3G, never ever turn off GPS...
I use the Facebook application a little too frequently, I read stuff using the Digg and Engadget apps, update Twitter via Twicca, listen to music via Mediascape, and take several photos.
Oh, and I charge the phone once every couple of days.

Since the last 026 update i have noticed a huge improvement, now lasts ffor about a day and half where used to last about 8 hours. I've stopped using taskkillers now apart from when i've finished playing a big game like need for speed which uses a LOT of ram. Looking forward to the 2.1 update.
Also, i got the 2600ma battery from ebay, bigger, but lasts nearly 2 days!

i always cut my web connection and i use taskiller
and my phone lasts also 2 days, but i have the original battery in it

SetCPU is a big help. At the very least throttle your battery when the screen is off.

I just use Data On Demand. No task killers, no startup manager, no root. Firm 026. Bluetooth and 3g on, and my batery (original) last 2 days at least.

Sounds almost like the kind of solution Apple would give to fix poor reception...
http://www.intomobile.com/2010/07/1...ntenna-issues-advises-carrying-a-spare-phone/
Personally I resolve my battery issue by only turning it on when people want to call me. I've set up a roster with precise times when I'm available for contact. Callers must contact me within a select 5 min window otherwise they must wait until the next one. These are seperated by 2hr hour 'no call' times, as well as a complete call 'blackout' between the hours of 10pm and 6am. If I want to call people, I keep 50c in my pocket and use a payphone.
So far my battery has lasted 8 weeks.

That's a lot...!

3 hours of talk time a day on ANY smartphone is going to drain the battery. I dont think there is a huge amount you can do really. Sounds like you have done all the sensible things already.
That being said, i am on a RB..26 FW, Rooted with ADW Launcher. I get about 2 days from a charge, using FB app all day long, a few calls a day, several msgs and general playing around with the phone. i dont run any task killers, cpu management tools or even disable 3g connections. maybe i just have a good one

Do you reckon rooting helps...?
I'm on 26FW too (actually, that's a lie, I just checked, and am on 24)... but anyway, I also use ADW and am on an Australian network, so all thing being equal, I should be getting similar... although I only get about a day and a half... Well, I usually put my phone on charge every night, and it's about 50-60%, but obviously the drain over night would take it a little too low for me to go another full day...

I just bought setcpu from the market. First day with it and juice defender (lite) running it's drained 16% in 12 hours.
Previously, i would be at 40 - 50 % by now.
Of course, you need root for this solution.
Running 020 firmware as i haven't got around to backing up and updating as yet.

So which fixed it then?
You need to make a single change and observe

I used setCPU too, but i had problems with it.
Every 2nd time when i activated my screen and went passed lockscreen, my launcher was forced to a close.
This procedur has been with differents launcher like ADW, GDE, default launcher.
regards DauL

Does rooting help the battery life alone without any apps? And how?

I went ahead and got the Muegen 1800 battery and im now running generic 026 FW. I fully charged my phone two days ago and I use it quite a bit while at work and what not and this morning I have 26% still remaining. Not saying you should go out and buy one of these batteries but ive noticed a definite improvement.

I charge twice a day. Heavy data use and I need my screen bright as lot if it is out of doors. Rooted 026, with setcpu. About, 66% of my drain is the LCD. My GF with her iPhone 4 gets about 36 hours and she hammers it more than me- never turns any radios off either. Grrr... drives me nuts when i have to jump through hoops to get back home from work without a dead phone. Incidentally, what moron put the charge socket on top? Means we will never have a dock we can just drop it in when not carrying the damn thing /facepalm...

if you're using set cpu to 200mhz that is probably a factor as well, doesnt the phone sleep at 100mhz stock?

I think they put 450 hours because they know no one is going to go 19 days without at least turning on their screen, which would invalidate the test

Maybe if I put my phone in airplane mode and deleted all the homescreens and prevented anything from starting up, it might last that long.

Since the JI6 update, battery life does suck. But "slightly better than a G1"?
Riight.
After reverting to the JI2 radio, I can believe it. I get about 6% loss each night with syncing and wifi polling turned on.
Turn off syncing. Disable wifi. uninstall setCPU. never turn the phone on. I could see getting 450 hours.

So I was looking over that link...did anyone else notice the part:
"Create your own content with the 5.0MP camera/camcorder with autofocus, 3D sound, LED flash, 720p HD video recording and expandable memory up to 32GB."
My Vibrant doesn't have an LED flash. Not sure why they would advertise that.

According to my last few tests i'm getting about 350 hours of standby with my phone on:

i'm sure if i didn't have a bunch of stuff installed i could get 400+ under perfect circumstances.

450 hours under the most ideal circumstances (ie wifi off, cellular locked onto a single tower, not moving, screen off the entire time, no background sync).
Under real-world usage that's not even close of course, but if you're going to fault the vibrant/galaxys on this, then you need to fault every other manufacturer which tests under the exact same circumstances.
The fact that you're bringing this topic up indicates that you believe the GalaxyS isn't accurate and some other phone specs are more accurate.

LOL. 6.5 hrs. talk time with screen ON?!!!
Such BS!
My stock JI6 Vibrant lasts 12 hrs. with fairly light use: less than 10 minutes of talk, occasional email checking (4 accounts). My international Galaxy S was the same.
My wife's iPhone 3Gs sees a little more talk time, yet usually lasts three times longer.
On JI2 my Vibrant was getting about 15-16hrs. Still crappy, but closer to getting me through the day.

I reality you can store your Li battery in a fridge at 60 or so % and it will loose just a tiny bit over a month

What exactly does "sync" do for my gmail account? Would having it sync "updates only" prevent me from getting mail immediately, or is it only syncing contacts and calendar?
Just curious if I can turn those off to save some battery.

450 hours under unrealistic circumstances.
I just expect my phone to be as advertised.
450hrs/100% battery standby mode means 9 hours of sleep [who sleeps that much?], we should lose about 2% battery.
But instead like this post:

WITH THE ALL SIGNALS OFF... i think we have an issue.
I believe Galaxy S isn't accurate, and they aren't accurate.
I love my phone, and I don't complain... and haven't complained.
Just pointing out the false advertisement.

I'm not really complaining either. I'm not under any contractual obligation and I paid cash for my Vibrant. If I wanted a different phone on a different carrier, I'd have it. That doesn't mean I'm not going to tweak things here and there, experiment, and load custom ROMS + kernels to get the most out of it, including battery. Advertised talk/standby times have always been a joke; from all manufacturers.

Update Patched Standby Drain

Loving this update even more. Yesterday installed update and usually my phone would drain 3-5% each hour not in use but today. My phone was stuck at 98% when I came back from 2 1/2hr meeting, I was amazed.
Also noticed the startup sound is now muted when in silent. It wasn't a big deal before but nice change.
Camera appears to be a little more snappier as well .
Verizon did really good with this update. Droid Turbo is really turning into perfect phone imo. Now we await Lollipop.

You can also try booting into Safe Mode, and then re-adding your accounts. I did that and it fixed my battery drain problem it seems.

CDMA is a fallback if you lose LTE. Sounds like tower trouble in your area.

I had full 4G here before update...after I get this! If I turn off WiFi..I basically can't use my phone! BTW I just did a factory reset and cleared cache..

It sounds like you are having tower issues in your area.

i noticed before the patch when i took my phone off charger it would drop to 99% battery right away, now it actually takes a bit before it drops.
this seemed to be a legit patch for little bug fixes.

The battery seems a little better for me too.

I just got the Droid Turbo this Monday and left the store after it was updated. Attached is a picture of my battery usage. It doesn't seem right to me. Can someone also explain how to read it with regards to "time on" etc? Many thanks for the help!

what doesnt seem right? that looks normal if u want to look at your screen on time tap on the screen line and it will give u how long the screen was on in between charges.

So 1 hr and 20 min left on battery seems right with a 20% usage for cell standby?

Battery drain isn't linear and drain slows as you get further into the battery.
Were you expecting it to stay at 100% for 15 hours or something?

Maybe I am not understanding what the screen is telling me 100%. I took it to mean that there is only approx 1 hr and 20 min left on the battery? Is that not correct?
With regards to the cell standby and other things using the battery, my assumption was that 20% battery usage by the cell standby was rather high. In searching online, I have seen people post that it should be around 11%. Is this not accurate?
Thank you for the help!

it means you've been off the charger for 1hr and 20 minutes and used 5% battery. As to standby time it's hard for me to say as I haven't updated and heard it's gotten better.

Only get ~2 hours of on screen time - "Android System" battery drain

I am on the latest 7.0 beta, T-Mobile version, I am getting pretty frustrated. I only get ~2 hours of on screen time. Right now at 30% and Android System has used 1350 mAh and CPU total is close to 5 hours.
Attached some pictures from yesterday and basically the same exact thing - maybe one of the packages listed is killing the battery?
I know there are a lot of posts about this issue but nothing that I've found useful unfortunatlely.

Did you try a factory reset? That help me get good battery life.

Been thinking about doing that, but not sure why it got really bad all of a sudden. I could get 3 to 4 hours before.
I think I'll wait until the official release is out and then do a reset - hopefully it comes out soon.

Still on 6.0.1 & Android System is my #1 battery drainer.

I am getting pretty fed up. Thought the new updates would make it better but no go for me.

If only you got root, I strongly recommend using Myandroidtools/disable service. Samsung roms sucks pretty bad, I have never ever experienced something like battery drain on other phones. Since I disabled 80+ Google Services and some samsung bloat, android system takes about 2-4% drain after a whole day. I am using Renovate on nougat.

Looks like a lot of you are very unlucky. My battery life is superb! At the end of the day I still have ~35% battery remaining. I recharge every night regardless of how much battery I have left, so it does me just fine

I would strongly advise to stay away from any of those 'fancy' package disablers.
They do no good and often deteriate things. I have on average over 8hours SOT and never used disablers.
Most Samsung apps don't put any drain on the battery. It's things like Facebook etc that hog resources.

Yeah, if only i got Facebook apps installed. I have fully working locations, notifications and other stuff - most of services I disabled are feedbacks, silent loggers and stuff I dont need or use. Only corrupted app is Gmail - which I don't use.
I got sync switched on, lots of calls, auto brightness, voice assistant and usually get 5 hours SOT during my usage which isn't bad at all.

So not sure what did it, but I installed Greenify and also changed from 1080p to 1440p and I get about 3ish hours on screen time. Still terrible but will do for now.
My phone also feels faster after changing resolution back to 1440p. So weird.

Disable ubication and always on display.

I mean location. Aod takes almost 40% of battery in 24 hours.

I remember Samsung saying it only consumes a couple a percentage points.
This article tested and it's nowhere near 40%. And I use the phone about 15 hours before it gets charged again so it should have a huge impact.

Okay, stop reading useless news and try it by yourself. Phone dont go fully in doze mode with AOD on and keeps light and other sensors on like proximity to put more or less light in the aod screen. You are complaining about **** battery and I am telling you that I have tested how aod can take 40% of battery in one day. You really believe samsung? Come on...

I really don't think you're right as that's not my experience either. I cited the article because usually the tech websites have some experience - my anecdotal data, or yours, doesn't carry much weight.
As posted before, my screen time has increased and keeps going up. Got near 4 hours of on screen time today. Greenify must have killed a process that was putting the CPU on overdrive and which showed up under Android System. I shouldn't have to take the time to find fixes however since Samsung and the Doze feature should be doing this already.
I appreciate your advice, no need to get upset we're just having a discussion...

I don't really see a discussion in the fact that AOD uses a lot of battery if you keep it on all day, it's pretty much guaranteed that AOD is the main culprit. And your own experience with your phone and its settings is worth a lot more than the experiences from some tech website. Everyone's phone/settings is different.
