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.
HTC shipping crapy product again!
Customers should not have to put up with this crap and be the beta tester!

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

Do you know what your time since charged was? (I wish it would display total time since charged there...) The "since charged" definition seems weird and hasn't reset on my phone in ages... I've tended to use "since last unplugged".
Pandora appears to be your #1 wakelocker. eBay mobile seems to be pretty bad too.
NetworkLocation wakelocking can be eliminated by unchecking all of the location features in Settings except for when you want network location/GPS.

I assume you were listening to Pandora during that time, in which case, that wakelock is normal. Playing music from your device will also hold a wakelock when the screen is off. If you weren't listening to Pandora at all, then something is wrong.
Whoa. Why the heck is eBay holding that wakelock . Check your notification settings and if it's still holding it, clear its data and try again. Otherwise, I'd uninstall it. I always use the browser to access eBay anyway.

No. In the device settings, turn GPS off until you need it and leave network location checked/enabled. Go into Fancy Widget under weather settings and UNcheck/disable GPS location (GPS is unnecessary for weather updates), verify that network location is checked. Then, I would recommend changing your refresh settings (to update less frequently). I'd bet you have it set to update more frequently than an hour. I also use Fancy Widget and mine is set to 3 hours. This should take care of your network location wakelock (unless another app is also updating with network location).

BTW if Wifi is on but not connected, in Froyo it seems to scan way too often regardless of build.prop setting. Netloc should wakelock less if wifi is off.

Hey ent i noticed after trial and error that phone stays on 100mhz while charging ?but when disconnected it hits deep sleep and there has been no bad wakelocks.wonder if thats y we get slow charge

I installed BetterBatteryStats because I was curious as to why my phone always seemed to drain so quickly. I am rooted and running infused 1.5.3. I have very few widgets, one that actually accesses anything, and don't do much but surf the net or the forums in the morning. I would unplug it at 6:30 and go to work. By about 8 or so I would already be at 90% or less. That was me hardly using it. Well I hope I got my answer. Apparently Beautiful Widgets was KILLING me on the wakelocks! I wish I took a picture of it before I uninstalled it but jesus it was bad! Thanks for the good info I'm gonna keep an eye on it and see how it does.
Oh funny thing is, I was not even running Beautiful Widgets! I use Fancy Widget instead lol.

No, slow charge is a few other things. ALL android phones wakelock when charging.
The phone shouldn't count CPU/screen/etc usage against charge current at all but it does. It seems to do it less so on GB. Still does it, but the spikes seem lower even if I crank stability test. Gonna be a while before I can test a navigation run.
Seems like on GB, difference between screen off and running stability test with screen on is about 200 mA. Haven't tested in that much detail on froyo. Another way of putting that - putting the screen on and cranking CPU will reduce charge rate by at least 1/3 of the 600 mA charge limit.

[Request} Wifi Calling toggle widget?

It would be super handy to be able to toggle on and off without going into the app. Anybody up to it?

Keep it enabled and toggle on and off wifi with beautiful widgets or power control and boom same thing!

While that is an option, it's not quite the same thing. There are times when I simply want to toggle off wifi calling quickly and keep wifi connected. Am I alone?

thats a very dumb solution considering how much wifi calling running drains the battery.

A widget would be nice

http://forum.xda-developers.com/showthread.php?t=1098687
I wrote some Tasker scripts that provide an "Enable" and a "Disable" button for wifi calling. They require Tasker and the Locale Execute Plugin.
It essentially freezes/unfreezes Wifi Calling so it doesn't drain battery when not in use. It also toggles wifi on when the app is enabled, and when disabled (if necessary)... it gives a few seconds after WIFI changes to allow for the app and phone radio to not cause force closes.
An enterprising individual could *probably* combine the two scripts into a single widget.

On the Vibrant, at least, the Wifi Calling App is frequently the #1 user of CPU time even when Wifi calling itself is disabled. I don't know if it has the same problem on the G2x, but if you check with SystemPanel's logging, you might find that it does. This is why some of us go to extreme measures to freeze/disable the app when not in use.

[Q] how to prolong battery life?

im running kg6 icbinb but i feel like im using it too much, i use it for music, work out for like an hour and text heavily and facebook and youtube... i tried juice defender but it made me loose my connection most of the time...

Juice defender turns off your data connections when the screen turns off, so that's probably what is happening. The paid version lets you maintain connections with specific apps you choose, but you may want to try other battery saver programs to see if there is a free one with app control.

Alright lol thanks man!!

JuiceDefender does not work well with any stock based rom like Weapon. For stock based rom you have to use the new beta version.
