Saving battery life

Hi all.
Looking for some serious help. Coming from a Samsung vibrant. I need help with how to save battery life on the sensation. I have been off charger for 5 hours and 51 minutes and am down to 41%. Is this normal? I have been only texting really. I got my data from battery monitor.
Thanks in advance. Anyway to make this better?

It all depends on what you're using the phone for. I'm at 55% after 12 hours. yesterday I got 17 hours. if all you're doing us texting then no,thats not normal. but I suspect you're probably doing more with it than you realize since its a new toy.

He prolly has running wifi as well?

Stop Android from phoning home and you'll save greatly on battery life.
Best way I've found to prevent battery drain, is to stop Android from phoning home.
Once you use an app like Autostarts to stop unnecessary things from starting up all the time on their own and also block a couple ports that are not always needed via an app like DroidWall, you'll see great battery life. Also see other details in that link of things I turned off to increase battery life amoung other benefits.
For now, I can only speak for seeing the difference while using a Nexus One ROM on my HD2, but I have way better battery life, GPS lock times and faster device boot ups than ever before.
This is yet another one of the reasons I must wait till the Sensation is rooted and unlocked. Because I'm not using it while it's running things I can't better manage, so they don't drain my battery.

How did u get that much? I have battery monitor as a widget. I also did not charge the phone all the way up when I first got it.

Well to be honest for the 8 hours I'm at work, I use it light. texting, a few calls and about 30 minutes of reading pulse and playing games. However the next 8-9 hours I would consider moderate to heavy use. I have no monitors or anything running, just running straight out of the box.
I'm at 34% after 14.5 hours today.
I charged it fully the first day, ran it to 0, then charged it fully again last night.

Did draining it out help? It is really killing my battery. When my phone idles it loses about 7 percent an hour. Is this normal?
Sent from my HTC Sensation 4G using XDA Premium App

Mine is at most 3% per hour so I would say check if you have any running apps that aren't supposed to be.
I suppose draining could have helped but I have no way of knowing for sure

Yeah I killed my battery in 12 hours with decent use and then charged to 88 had to go but now down to 35 three hours later ....thinking of draining battery and then charging

I think mine's even worse. Phone was off charger at 100% at 11am, by 1:30PM it's already down to 80%ish. By 4PM it was down to 40%ish, got it charged up to about 70%ish around 6PM, by midnight I was around 6% again.
So I think I'm losing around 10%/hr. That's gotta be abnormal, and the battery gets really hot too. At the moment, I have several speculations:
1. Death grip causing the phone to work harder to find signal, and tmo's coverage kinda sucks in my town
2. I have defective unit/battery
3. Some apps behind the scene are killing it. But I've checked what's running behind, even turned off unnecessary stuff using autorun manager. Auto sync is turned of only for gmails. Weather, IMAP mails, pulse, facebook etc are set to pull in couple hrs instead hourly. The battery life cannot be worse than my 2-yr old HD2.

Hey guys. Have you considered bump charging. HTC advised the idea for the HTC desire battery and it in most cases doubles the battery.
Sorry I can't be more specific bit I'm on my phone. I have found the relevant link. Read the 1st post. I'm gonna do it when I get in from my gig.

Bump charging kills the battery in long run.
If you have to do it to a brand new handset it can't be good news.

I'd suggest uninstalling battery monitor. I had installed it on my g2x and immediately saw my battery percentage drajning more quickly. Probably because its always running in the background.
The best tip I can give for better battery life is to minimize what you allow to run in the background. Get rid of any task killers, set Facebook/Twitter/Email/etc to sync less frequently, turn off wifi if you're not using it so its not scanning for networks, and so on.
Also install juice defender from the Market. Its free. It has greatly increased my battery life.

I installed the Plus version because it allows wifi control. I just use the default settings except I change so it doesn't disable wifi. I do that because I use wifi calling at home so I dont want Juice Defender turning off my wifi. I always turn it off manually when I leave the house anyway.

Yea Balanced Settings is good if you don't mind it managing your wifi too. In the Plus version I selected Customize instead of Balanced. The only thing I changed was the wifi setting. There's a ton more settings to configure but the default ones work fine for me and I don't have the patience to sift through them all anyway lol

I agree but recommend you take the time to set up each setting on customise mode and you'll be amazed how much extra battery you save fr!!om the default values. Only takes about 5 mins

[Q] Display using battery [solved?]

Has anyone ever heard of an instance where the display drains the battery while off? 4 hrs on battery, display using 54%, all others using 4% or less, and display off 85% of the time. 20% remaining.
Just curious. Probably gonna GR then reflash
Sent from my SGH-T959V using xda premium

Your display is always going to use a large portion of battery. Being on battery for only 4 hours may be misleading. Let your phone run through most of the charge and check again.
As you continue to use it, other apps and services will contribute to battery drainage, in turn lowering the percentage of juice shown used by your display.
Im not trying to imply you are wrong. You may have an issue, and I could be way off base. Just something to think about.
Edit: I re-read your post. It ran through 80% of your battery in 4 hours with minimal use?

Thanks. I was actually just seeing if this has ever happened to anyone before. There has to be something wrong. Just a one day fluke I guess cause today it seems to be going ok so far. I'm just gonna start from scratch and try again.
Tried to thank you for responding, but alas, I am limited to 8 per day. I'll get you tomorrow.

My display also drains a large portion of my battery, but never THAT much. Is your brightness really high at all times? If so, turn it down.

Your battery dies really fast while display is off?
The day I posted it was dying super fast. I have not changed anything and it seems to be better but still draining pretty fast. Running better batt stats app for a few days to see if I can catch what's doing it.
Someone in anton's kernel thread said that the first few charges went great but all of a sudden it's draining fast. This is what happened to me. I'll report back what I find out with the app.

Seems to me that the phone is having a hard time going to sleep soon after use, wifi may be keeping it awake. i have wifi on all day while im at work and the awake time seems to be higher right when i get into work. doesnt sleep for the first few hours.

Haha nope not quite we mean like tap the "screen" entry so we can see how many hours of screen-on time you've had, and also possibly tap the usage graph then it shows when your phone was awake, when WiFi was on/off, when it was charging etc.

As much as I do like the phone. I'm quite annoyed at the battery life and am thinking of ways to improve it and etc. but it doesn't seem to be working. I get like 8 hours and by then it's at 30% MAX. Usually around like 20 or so. 10 hours and it's pretty much dead. Am I doing something wrong? my screen is only on for about an hour and a half or so, maybe 2 hours. Lowest brightness setting, 4g off, 2g on, wifi on.. that's about it. I mean as much as I love HTC, I can't love this battery life...

Yes you're doing something wrong or have a faulty unit. Make sure you flash a good ROM (I'm using aokp) and that's it. I have my screen at about 25% brightness and here are my stats which is quite acceptable.

This was back on CM. That rom game amazing batt life.
I don't have the screen time pic but it was just over 4 hours. Still had 1/5 of the battery left too! With this phone I just leave gps, wifi, antenna and sync on. It's so rare for me to NOT last a full day that I see no point in being conservative about use anymore.

[Q] Is This Good or Bad ?

Hello Guy . Im using The Carbon Rom 4.2.2 on my Verizon S3 .. Over All I love the ROM , but like Any ROM I use my Battery life Will be Gone with in an Hour if I use it frequently. just in a 20 Mins I Went To 100%-89% with Brightness As low as it can Go . no WiFi. No GPS . No Sync .. I don't think that's Good Enough .. Who can help me and save my Battery Life

Sent from my SCH-I535 using xda app-developers app

I would try a custom kernel that lets you change clock speeds when the system is off. Right now you have 28% battery drain. I usually have anywhere from 2-9% with the phone of most of the time. A custom kernel will also allow you to change govoners and schedulers which can sacrifice some performance for bettrr battery life.
I couldn't upload pictures but on clean rom 6 running ktoonse kernel I got 6hrs screen on time 13.5hrs up time and a 6.4% battery drain. That's with a 4400mah battery so you should be able to get at least half that time with heavy use (my stats are at heavy use) and that only ran my battery down to 30%

High CPU usage/no battery life.

I need a way to debug my phone and figure out what is causing such high CPU usage and poor battery life. After startup, my phone sticks at 100% until it freezes and restarts but sometimes I get lucky and it goes down a few percentages but freezes again when I start multi tasking a bit. I don't know what changed. Any app to debug or log what's going on?
Also my phone will read a low battery amount and when I restart, it jumps up 20-30 points

Sent from my HTC Sensation 4G using xda app-developers app

Install Wake Lock Detector to find out which process is hogging your CPU time.

From what I can tell, all the normal startup apps (mesages,facebook,widgets), are using full amount of CPU. All of them. The blue bars were full. That's for the few minutes after startup being 100% usage. Still investigating the random spikes that occurs while using my phone. It's a matter of being able to open and use this app as my phone becomes unresponsive

So I've been running apps and periodically monitoring my CPU.

It happens often with dolphin, tumblr, games. But they don't appear in wakelock.

What's your battery ?
4 hours is very low. Maybe you need new battery..
And which rom exactly do you use ?
I used Inspiration 1.0.1 for a log time and i had the best battery life on this rom. it works fine with lower CPU/GPU frequency. Vipers 5.0.0 also seems to have nice battery life (i'm on it now).
