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

Have you tried a different rom? That one should have pretty good battery life though. If you are doing EVERY single thing that, that thread suggests.. you should be able to have your battery last for a week.. He takes it to the extreme. VERY well done though.

you may have a bad flash...occasionally a reflash may fix it if you haven't tried.
with zeus, i don't recommend any other external cwm flash tweaks if you tried them

Maybe you gotta bum battery.

does the ics theme have anything to do with the bad battery life?

You seem to be the only one having this problem and if it's when you try other roms as well then it's probably a hardware issue.

About 33 hrs w/ WiFi OFF, 30 hrs on. With use: calls, messaging, Facebook, ect...... maybe about 22 hrs. Running apps all day are GoLauncher, GoPower, Magic Locker.... ect..

i get about 14 hours before i have to charge on a regular day

Cell signal quality and whether the cell radio is on make a huge difference for me.
I spend most of my time where I have wifi and now turn off the cell radio during those times, getting upwards of 30h on one charge (including occasional cell radio usage). Before I did this, I'd usually get through the day but not much more, around 14h.

I'm currently using Easy Battery Saver. It is making a lot of difference. Been playing around with the different settings. I will report back after a full charge than discharge.

Why does it seem like my battery sucks. Or at least when i listen to tune in radio at work. 8am ill be at 100% and if i listen to radio for a couple hours by 12 noon ill be at 15%. That listening threw Bluetooth, wifi and GPS off, brightness all the way down. I no 4g kills ur battery way faster. But even if i turn 4g off battory still dies fast while listening to internet radio.
Any ideas why

Are you the type of person to press the home button when switching in between apps? If so they're running in the background, and apps like Facebook can eat up CPU usage. Bluetooth and radio apps will do the same.

I took it off the charger at 6:30, used it until 8:30, turned it off until 12:30, had a good signal until 6:00, had bad\no signal until 10:00.

Actually I do always hit the home button, to get from one app to launcher to another app, ext. If nor home, how do u get out of the app? Back button?

Sent from my SGH-T769 using xda premium

Fairly typical. GPS is always on 24-7 and wifi on most of the time when home. Often end up charging and then taking off charge before bed so I get a 7 or 8 hour cruise mode with no activity to start off each battery stat as you can see by the plateau at the start. Over clocked @ 1344 w/ screen on, flat clocked with screen off and no undervolting so its not too bad. As soon as I move/copy/paste files or anything leaving screen on I see drastic drops in battery life but typical medium use lasts all day no prob and battery left to spare.
Sorry edit...... this is on my G-Nexus with Paranoid Android and trinity kernel.
My a500 on Flexreaper Extreem does about 25-30 hours with fairly heavy use. 40-48 hours when mostly idle. Overclocked @ 1504 screen on, 1000 screen off w/ Minor undervolt. Lovin custom roms !
WOW.....EDIT !!!! : I'm a tard. I could have sworn this was a Galaxy Nexus thread. I apologize, don't know how I ended up here.

Tune in itself will drain your battery. Love the app but I use it sparingly as it kills any phone I've used it on.

[Q] Battery Drained 99% Overnight?!!

Hi! Last night, I charged my battery to 100% then left it on overnight, turning everything off (wifi, bluetooth, notifications) and made sure to clear all running applications. Usually, my battery only drains about 5-10% during the 8 or so hours that I sleep, which is what I expect. But all of sudden, last night it drained ALL THE WAY. When I woke up, it was at 1%!! Does anybody know why this happened? I know that the reception at my house sucks (dropped calls, failure to send texts sometimes, etc.), but that never really hurt my phone that much overnight. I'll upload some pics of my battery stats. I appreciate any help!

Your phone didn't go into deep sleep more than likely.

Was your battery old???....it might have lost its power to charge

This app could help.

It has to be a rogue app. I would fix permissions, wipe caches, and reboot. That should fix the problem, if not, you will probably have to reflash your Rom.

You are the 1%.
But no seriously. It's probably a rogue app.
By any chance do you live in the Fort Wayne area? This happened and no signal will quickly kill a battery.

I decided to look at your pictures, and sure enough, you have 0 signal for pretty much the entire night (red bar) which kept your phone awake the whole night. At the end you have so-so signal (mustard color). 92% cell standby power usage. Yup.
So this can be chalked up to signal issue.

If your phone wasn't in a different spot than normal, then perhaps there was a network outage in your area overnight.

I had cell standby at 90 or so % one night too and it drained me down to 40% batt over night. It only happened once tho
Sent from my SCH-I535 using xda app-developers app

You can put it in airplane mode if the bad signal keeps draining it. I have to do that when I'm at work. Used to be I would get to work with about 85-90% and 7 hours later with almost no use it would be down to 20%. I switched it to airplane mode at work and only lose about 2% over the 7 hours now. (imoseyon's lean kernel with a cpu screen off profile also helps)

3G battery "drain"

So basically I'm trying to understand why 3G reduced drastically my battery life. I'm not saying that I'm using it "actively", but I really need it idling.
Sometimes I have poor signal, and sure, it drains a lot of my battery... But while I have good reception battery drains fast too. I'm rooted and using stock Jelly Bean. My network have no support to fast dormancy (I'm assuming it's true because Better Battery Stats used to show a lot of time spent on FDCompleteTime wakelock before disabling it), so I disabled it. After about 7 hours mostly with 3g turned on I have 52% of my battery. A hour and a half of screen time. I do understand 3G drains my battery while I'm using it, or while I use the phone. That's ok, I accept it. But while idling is really something I want to know why...
Anyone else is facing the same?
