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

Does it drain when the battery is removed from the phone?
Sent from my LG-P999 using XDA App

you should download a cm7 nightly my battery lasted from 10pm - 9am with 30% than i put it to charge

You can either do a factory reset or NVFlash CWM and flash a ROM to see if that fixes things. If not, then defective battery.

What these guys are saying is most likely, especially with that kind of drain. But also make sure you don't have any crummy apps, it apps that run when your phones off. Ex. Some weather apps run in the background and draindrain

You guys. He said that his phone was OFF while the battery lost its juice. It has NOTHING to do with what ROM, KERNEL etc etc he is using. Now for the op; simply just get a new battery and check if the problem persists.

Try the same test with the battery completely removed.
If it doesn't drain that fast - Then the phone is not shutting down properly, and most likely is the result of a nasty app.
If it does still drain that fast - Then the battery is probably faulty.

In your original post when you said you turn the phone off at night, you do mean actually turning it off right? Like shutting it down and not just turning the screen off, right? Just making sure we're all on the same page. If the phone is powered down then it can't be an app because apps can only run when you're booted into Android.

Then its the battery. I had the problem with my g1. I would load the maps and use gps. It would say my battery is around 70% then after like 5mins the phone would get hot and then it would say i was at 30% or lower. Swap out for a new battery and it didnt do that anymore.
My g2x is kinda doing the same thing. But its a little slower. I turn the phone on in the morning 100% battery. Then use it for about an hr. (95-80%battery) put it in my pocket. Then about 2hrs later it at 40-35%. And the phone feels warm.
Also check your battery to see if it had a lump on it. If so then its a bad battery and needs to be replaced asap.
I ordered a replacement on ebay should be here by next weekend. Only $4

I had a problem like this and still do at times. Part of it was the stock kernel I was running and the other part was the fact that the phone was not fully going into the low power state it was supposed to. I now only loose about 5 to 7% in the worst cases. That is better than the 20 to 30% I was loosing before.

[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?

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.

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.

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.

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.

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.

I find that when I have my phone unplugged for like 3-4 hours it drains very quickly once I start using it. For example I'll unplug at like 7 or 8 and go back to sleep, wake up 3 hours later or something. When I start to use my phone it seems to drain a lot quicker. Is this normal for you guys?

Does it drain much during that 3 hour interval? You could try using an app like CPU Sleeper or SetCPU that allows you to turn off a core when the screen is off.

I love the battery life on Synergy 1.3! I haven't flashed to 1.4 yet, kinda liking where my set-up is right now. I'll probably wait until there's a few of the kinks worked out yet.
But yeah, I charge my phone overnight too...It usually comes off the charger about 8am, and at midnight I still have 50-60%, depending on how my day went...Some days, I only have to charge every other...

Looks like you're using about 12-13mA while idling, I am assuming you had mobile network and wifi off? I'm typically at around 24mA with wifi idling

Nope. Data and wifi on although I have sleep set to never when plugged in. I don't think I have anything set to auto update besides push mail though so it probably slept all night with me
This is standard battery as well. I just added the lean kernel and I am getting even better battery life. This is with mild screen time and 2 hours of pandora. You can see in the screen shot that it was only really awake when I had the pandora running.

Crazy battery life.....anyone have comparisons between this and 1.4? Would be interesting to see if the claims by some is true about the additional drain.....

It's lack of apps honestly. I have nothing auto syncing. I'll sync it when I get in the app. Also using better battery stats showed me an app that was wake locking. The lean kernel and battery saver script I'm sure are helping. No need for an extended battery on this baby.
