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

Juice Defender

Is it worth it?

I use the free version and swear by it. I have exceptional battery life when using Juice defender. I have gone 16/17 hours before without needing to charge with moderate phone use. The only difference between the free and the charge version is that on the pay version you can create your own profiles. I just use the standard profile and it is awesome. Download the free version and give it a try.

Totally worth it.

thanks, I'll ive t a try. I read some palces it does mroe harm than good

How does turning the data off, then turning it on every 15 minutes do more harm than good?
I use it if I'm in a 4G area or really trying to stretch the battery out. It does work wonders!

I use the free version and notice the gains. usually see about a twenty percent gain

Absolutely, although I have a strange issue with the service getting killed since I got the G2x, still love the app though. I have UltimateJuice btw

i bought the ultimate version and i never know how to do the settings so i ended up giving up on it.. and just manually turn wifi off and 2g on when i stop using the phone >_>

I installed the free version and it unstablized my phone. There are some Wifi apps that will turn off your wifi, when you leave your home automatically. Search WOOFI in marketplace. Or Auto Wifi Enabler.

Ya I had issues with reboots and instability while using the free version, it would also cause GPS to shut off and I would need a reboot to get it back. Just as easy to toggle it my self.

I uninstalled also. I was having issues receiving POP email in a timely manner. I had it set to check every half hour but sometimes four or five hours would go by then a ton of emails would flood in. I am going to spring for the next step up because you have more control over individual apps and how they connect. I will post back with results.

for those saying it works wonders are you saying this as someone who keeps wifi and gps on all the time? wifi crunches the battery so if all this does is periodically turn it on and off it's not going to do much for me. i only turn it on when i need it.

[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.

Battery saver apps

Hey guys I would just like ppl opinion on the various battery saving apps that are available on the market.
Do you think they actually work? best apps(in your opinion) and best configuration to save most battery.
I have juice defender and and it always says that it is saving me somewhere around 1.6 but I'm not totally sure that that is the case.
I have not had it installed for the last couple of days and my battery doesn't seem to be noticeable y worse than when it was installed

I have stopped using them. I have think it depends in how a person uses their phone to start with. All of those options, can be done manually. I personally got tires of switching to different profiles for what I was doing. I haven't noticed much difference myself.
but, that is just my experience.

Yes well that's the way I'm going I think. They taking up space and memory on phone and not really getting any noticeable benefit from having them installed.

The battery on my phone is going iPhone-ish, I need one of the battery saving apps, Are there any decent ones yet?

I would try Bataria from the market. Its free, and doesn't use much resources to do its job. I think the best is to manually adjust different settings on your phone. Same results, nothing running in the background to do it.

I am using Greenpowe.

Battery apps are usually crap. The only ones that really work are the ones that modify how your phone's software works. And those almost always require root access.
If by chance you are rooted, I recommend SetCPU, Autostarts and Autokiller. SetCPU will allow you to set profiles such as throttling while the screen is off, which will save you a ton of battery. Autostarts will stop custom apps from starting with your phone's OS, which leads to less background processes. And Autokiller will ensure that you have plenty of free memory for less tasks being killed and restarted. That alone has the potential to make a huge difference in your battery life.

I'm not trying for snarky, but
An app can't save battery by running
But you can save battery by turning something off

My uncle uses juice defender, but I think it's better for the battery to manage everything yourself.

yeah I've been using Juice Defender. It does save some battery life.

If you have a horrible phone like mine, juice defender ultimate works wonders. My LG optimus m gets about 12 hours of life without it, and about 18 hours with it.

Mobile data off when not in use, thoughts?

I haven't really found anything solid about this, but I habitually (like conventional wisdom really) keep my mobile data off until I actually need it, then it's off again. And the only substantial difference I've found is that the cpu jumps around alot while connected. But what are your guy's thoughts on this?

Well I think it depends. If you turn off data and continue to use the phone, then you're probably saving some battery. If you turn off data, then turn off the screen and let the phone drop into deep sleep, the savings in battery is probably negligible.

It also depends on your area as well. I always turn my data off when I am around any wifi. I get substantially better battery life
