HTC EVO 4G :: Possible Battery Saving Tip

Jun 22, 2010

We don't officially have 4G in Denver yet, but I've found two locations that I get a good 4G signal:

Near Elitch Gardens (LoDo)
I-36 near Sheridan

So the other day I was messing around with the 4g and accidentally turned off the "Mobile Network" option in Settings > Wireless & networks. When I was in the 4G area I didn't notice because everything worked fine. But when I left the area, I had NO DATA coverage.

Of course I thought that the Sprint network was down (3G) maybe due to upgrading and eventually called Sprint to see what the deal was. Of course eventually realized that the network wasn't down so it was my phone. Was going to be driving by a Sprint store anyway, so I stopped in. Rep noticed my stupid error right away and re-enabled the "Mobile Network" and data came back to life instantly.

But that got me thinking... Did I really have 4G working without the "Mobile Network" enabled? If so, that means that when I'm in a solid 4G area, I can disable "Mobile Network" and save some battery.

Was I imagining this? Or can you really turn off 3G to save battery while on 4G (or Wi-Fi)?

General :: Battery Saving App

Apr 26, 2014

I am planning on buying a new Android phone in place of my old ageing Samsung Galaxy S3 LTE. I'm choosing between the Nexus 5, HTC One (M7) and the Galaxy S4. One thing that is common to these phones are they both have Snapdragon processors.

My question is:

1. Is it wise or even practical to even install a battery-saving app for these phones? (as I heard such apps does work but also is a drain to the batteries themselves and resources/RAM)

2. What battery-saving app recommended? (I know I can easily search in Google or the Play store but there are just hundreds of them. I want to trickle it down to the "best of the best" or the "top one" out there currently?

HTC Hero :: Battery Saving Using Tasker

Oct 30, 2010

I think this should be possible, but I'll need a bit of help setting it up as I'm not yet competent with tasker.

During the day I have "data enabled" most of the time because if someone sends me an email I want to be able to reply. However data enabled does cause significant battery drain and my email only gets checked every hour.

Is it possible to create a tasker task that turns on "data enabled" and checks emails once an hour and then turns off "data enabled"?

HTC Hero :: Saving Battery Life

Jul 9, 2010

I don't have the Hero in front of me to experiment as I've given it to the missus.

Basically she lives in a low reception area right on the edge of where 3G signal drops out and her battery is lasting hours instead of days (when I tested it in a good reception area). I figure the battery is getting eaten up having to keep reconnecting to the mobile network.

She uses the Gmail app alot (not the other Mail app where you can specify when to check for mail). She would also no doubt have Facebook, Twitter, Gtalk, Googlemaps' Latitude, MSN Talk all active. I dunno if there's anything else that needs data in the background :P

Anyway, I'm wondering if there is a way to control all of these apps so that they either don't need data as often or super easy ways to turn things off/on. I guess what I mean is that if you have to go and check each of these things manually.

Sprint HTC Hero :: Wi-fi Battery Saving Method

Nov 2, 2009

I stumbled upon a new wi-fi setting yesterday that is fairly hidden and not mentioned in the manual at all, so I though I'd share it here.

First, a little background and explanation, then I will share my new findings with you all. It has been confirmed in other threads that the wi-fi radio uses considerably less power than the EV-DO 3G radio in the Hero. When you think about it, it's actually pretty simple because the signal only has to travel 100 or so feet for wi-fi, vs. several miles for the 3G radio. Whenever I'm at home or anywhere else with wi-fi, I always switch the wi-fi radio on, and have found that the battery lasts much longer. Whenever the phone is awake, and you're actively connected to a wi-fi network, it seems to shut the EV-DO radio down completely and rely solely on the wi-fi data for data. This has been confirmed as true, because there are some programs out there (i.e. Sprint TV) where you have to turn wi-fi off, because they will only access with the EV-DO radio. You obviously want to turn the wi-fi off whenever there are no networks around, because it will actively search for networks whenever it is on, and will run the battery down.

So, I noticed every time I would wake my phone up after I hadn't used it for a while, it would be using the EV-DO radio, and would take a few seconds to re-connect to my wi-fi network. I couldn't quite figure out why the phone would revert back to EV-DO when sleeping, then connect back to wi-fi only after waking the phone back up. Yesterday, I stumbled upon a new menu I hadn't seen before where you can change this behavior. Check this out.

Menu->Settings->Wireless Controls->Wi-Fi Settings->Press Menu Again->Advanced->Wi-Fi Sleep Policy

The description for this menu reads "Specify when to switch from Wi-Fi to mobile data."

Within this menu, there are three options.

"When screen turns off."
"Never when plugged in."
"Never."

The default setting is "When screen turns off." So, even with wi-fi enabled, whenever the screen turns off, your phone automatically reverts back to the EV-DO radio. As we all know, your phone is still transmitting data a good portion of the time, even when you're not using it. So, even with wi-fi turned on, the phone is still using the 3G radio to communicate while the screen is off.

I switched this menu setting to "Never" as of last night. This forces the phone to always use wi-fi whenever it is turned on, and you are connected to a network. Since then, whenever I wake up my phone it is still showing the wi-fi icon, and I haven't seen the EV-DO icon at all like I used to see for the first several seconds.

I was at home most of the day today, connected to my wi-fi network. I left the house twice for probably about 2 hours total, and I switched off wi-fi both times I left the house. I used the phone fairly lightly today, since we had a family day, but that still consisted of a good bit of browsing, some email usage, light texting, reading twitter updates every two hours, and half an hour playing a video game. Also, I always leave my GPS switched on as it never activates unless I open a program that requires it, and it always switches back off after I'm done. I took the phone off the charger at 9:30 this morning, and it is now 11:50 pm as I'm typing this. So, we're looking at over 14 hours today. The phone hasn't touched a charger since this morning, and I am sitting at 52% battery life, and I'm about to plug the phone in and go to bed.

I have never seen anywhere near this kind of battery life at the end of the day. I am usually below 15% after this kind of usage. I'm not sure if this was just a freak day, or what, but I really believe changing this one setting had a profound affect (effect?) on my battery life.

General :: Saving Battery On Android Device?

Mar 19, 2012

So after some research and Googling, I discovered that "Killing" your app is only worse or has no effect for your battery life. Even using apps that "save" battery only harm it even more. I've been told these were the fundamental things to save battery ever since I even got my hands on a smart phone.. Guess I've been asking the wrong people.

So, what are real ways to save battery? I'm a heavy phone user, often surfing the net or watching Netflix on the go. Dimming my screen is not enough, are there any other techniques to prevent my phone from dying? I've got an Android 4.

HTC Droid Eris :: Massively Saving Battery Life

May 18, 2010

I found that really saved my battery life was either during off 3G or installing Juicedefender, which helped, but it was still draining a ton.

What I did was I checked when facebook updated my contacts to once a day instead of the default. Which I believe the default setting was Every hour, because honestly I don't need it to check every hour for a profile picture change or a few things that I normally check on my own with the facebook app.

The way you do that is

Menu->Settings->Accounts and Sync->Facebook for HTC Sense->Account Settings->Change it to Once a day.

Also I recently found out that you can use your gmail account to have it check a work e-mail or another e-mail, by using pop e-mail, so I didn't have to leave my phone set to check my work e-mail every 15 minutes and drain battery life that way, and that works really well too so your just using your gmail account for e-mail, plus your gmail account pushes to your phone every time a new e-mail comes, which it can do for a work e-mail or your gmail e-mail.

The way you set that up is,

Login to your gmail->Settings->Accounts and Imports->Under Check mail using POP3->Click add POP3 account->Then start adding your work e-mail in there

You can also select Send mail as and add your work e-mail in there, so you can just use your gmail account to send e-mail, I would prefer to use IMAP, but since I am usually in front of a computer, cleaning up my e-mail isn't too much of a job to do.

But this is a great way to use less data and to save a TON on your battery, by the time I was done with work today, I was at 80% battery, when I am normally around 40% to 50%, and after a few short phone calls and showing my mom about 100+ phones from the 3D photo gallery I am still at around 60% on my battery.

Motorola Droid :: Battery Saving And Background Data

Apr 6, 2010

I just recently bought a Motorola Droid, and I was pretty shocked at how quickly the battery ran out of juice. I looked around on the net and found a tip that said to turn off the Background Data option, so I did that, but I find this to be a very convenient feature. I'm just wondering if there's some sort of app or widget that will let me quickly toggle the Background Data option on and off for a quick sync to push all of my stuff in whenever I want it.

HTC Incredible :: Battery Saving Rom And Kernel Combo Recommendations

Aug 27, 2010

Anybody have recommendations for a rom and kernel combo that would give some good battery life to our battery vampire of a phone?

I'm a heavy user, and I just think the incredible can be more efficient than it currently is.

I'm running the Skyraider 2.5.2 vanilla rom and King Kernel BFS #1.

The King Kernel is great when the phone is on standby, but when I am doing some web browsing or more, it drains the battery very fast.

I've also tried the Hydra Kernel stock speed undervolt. That seemed to give moderately better battery life than the regular .32 kernel.

I don't care about overclocking, 1ghz is plenty fast for me.

HTC Incredible :: Hydra Kernals - Get Most Power And Battery Saving?

Oct 2, 2010

i was wondering about the hydra kernals. I installed the latest overvolt hydra kernal. My question is when you go into idle, does it underclock for you? Or do you have to install undervolt to do that? Also can you install both overvolt and undervolt at the same time? (not literally at the same time but have both kernals at once to get the most power and battery saving?)

General :: Saving Battery In Constant Low Signal Areas

Feb 6, 2012

So I know it's usually best to place your phone in airplane mode when your phone doesn't have signal; however, are there any alternatives to this if you're in an area that constantly gives no reception? I live in the first floor apartment and I'm guessing the materials of the building completely kill my cell signal because I barely ever have more than one bar of signal if any signal at all. For example, my cell standby is usually about 50-55% time without signal during a given day.

I'm wondering if there is another setting or perhaps an app that will save some battery.

I have a friend that sent me this message today, which sounds like a great idea:
I've been messing with setcpu and trying out some underclocking profiles. Underclocking while the screen is off as well as reducing the CPU power has gotten me 75% battery left after 8 hours. This is with constant emails but no wireless, bluetooth, or gps. This is better than I was getting under windows mobile.

Big thank you to the members involved with the guides from the stickies!

The only problem I can't workout or find a solution from searching the threads is how to copy pictures/images from the web (on my desire) to use as, say, a wallpaper.

For instance I have pics on Picasa web albums, which I want on my phone.

Android :: Saving An Object For Use Later

Jun 12, 2010

As part of my widget, I use an instance of the Camera object.

This is what I want to do. The user will click on my widget, I get an instance of the Camera(if it's not already stored), use it, then store it. If they click the widget again, I want to use that same instance that I used previously.

I can't release the Camera(android.hardware.Camera) until the user clicks on the widget the second time. So the user clicks on the widget the first time, I get the camera and hold on to it until they click the widget again.

The problem I am running into is on the second click, I am trying to get the Camera again, which I can't because I currently have it in use.

General :: Droid 3 - Saving SMS To PC

Apr 22, 2012

I have a Droid 3 and I'm attempting to backup my texts and save them to my pc so I can print them out if I need.I have downloaded SMS Backup and Restore and PhoneLeash. From what I've gathered, Phoneleash only emails the texts that have been sent/received after the app has been installed. I do like the organization of the texts, though. For Backup, I have gotten my texts backed up and saved to my SD card. When plugged into my pc, I've been able to open it up in XML format, but the texts are so hard to read, due to all the coding. Also, it doesn't organize the messages very well. It put all the texts I've sent together and all the other person's texts together. It would take a long time to get them organized correctly. So my question is, is there any app the works like SMS Backup, but organizes like PhoneLeash?how to make Backup organize the texts correctly?
