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.

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 :: Not Saving Photos

Aug 10, 2010

A few days ago I had to perform a hard reset due to my phone not sending pic mails anymore. Since that hard reset, my camera has decided when it wants to save photos and when it doesn't want to save them. Has anyone had this issue happen to them? Do i need to perform another hard reset? Could it be a SD Card issue?

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?

Sprint HTC Hero :: 2.1 Battery Not Charging Fix

May 21, 2010

Today I took my Sprint HTC Hero to a Sprint store to upgrade to Android 2.1. In my opinion, I don't think it was worth upgrading the software. I really liked the options in 1.5 more especially the camera app. Any way, after getting home, my batter was almost dead. I pluged the micro usb cable into my Hero and attempted to charge it via an a/c charger. It started to charge from 10% slowly but then only went to 22% and stopped and stayed there for 2 hours. The back of my Hero was REALLY hot. I shut off the phone and let it cool and tried again. Same thing happened. I noticed that when you are using the phone and charging it in 2.1, the battery starts to die and it gets hot even quicker.Shutting the phone off and charging didnt help. What did and is still working, is putting the phone in Airplane mode, killing unnecessary running apps/widgets with the Advanced Task Killer by ReChild and then proceding to charge the phone.After leaving it like this for 30 minutes, the back of the phone was no longer hot and the battery percent went up from 22% to 33%, it is continuing to charge now.If you are having this issue, I suggest you use this method to charge your phone until the bug is fixed.This is such a pain because if your using Sprint Navigation in the car and your battery is about to die,you cannot charge it.The phone will remain on after using a car charger to charge it but the battery percent wont increase and it will get really hot.I guess we have to charge the phone before every use from now on? Android 2.1 is a lot of bugs. They made us wait this long for it and they have still failed to fix the major issues that were supposed to be fixed with this update IMO.

Sprint HTC Hero :: How To Get A Better Battery Life?

Jan 22, 2010

So, I rooted and installed fresh 1.1 a few days ago. The question I have is how is everyone getting better battery life, because mine has not changed, even a little? The speed has increased, but it's nothing to write home about. I guess I would like to hear from other fresh users to see what you have done to get more speed and better battery life and your overall experience with fresh so far. Don't get me wrong I love the look and it is faster. I'm just wondering if there is more that I can do to make it better?

Sprint HTC Hero :: Dead Battery

Mar 24, 2010

My phones battery died last night and now my phone can do almost nothing. It will turn on but I have no signal just a x and anytime I try to use almost anything I get a force close error. Everything from trying to dial a number to opening google maps. It seems like almost everything included with the phone will not work. I tried a couple of games just to check and they seem to work ok. Does anyone know how to get my phone working again or if a reset will fix this, or do I need to take it to Sprint? My phone is not rooted and has died before with no ill effects.

Sprint HTC Hero :: GPS And Battery Life

Mar 1, 2010

A month or so back I started running mine with GPS toggled ON all the time. (For apps to find a lost Hero it seemed the only effective way to find it was if GPS was on). GPS is not powered (or maybe very low powered?) UNLESS the GPS Symbol is showing at top of screen?

I've noticed NO difference in battery life with GPS toggled ON vs OFF over the last month. GPS (when toggled ON) appears to be actually turned on or off by particular Apps that use it.
Anyone? Am I correct?

It seems to be "common knowledge" and I think Android even says to toggle it OFF to save battery life but this seems to be not true?

I DO have an App that does turn GPS on but does NOT turn it off when I exit, which does drain the battery until I manually correct, which could be a problem, but I do see the GPS icon so I know it's on and draining.

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.

Sprint HTC Hero :: New Battery Makes Phone VERY Hot

Mar 30, 2010

I've had my Hero for a few months now and it has been wonderful. However, the other night, the phone wouldn't charge all the way, so I unplugged it, restarted it, and charged it and it charged up to 90% through the night. Last night it only charged up to about 50% give or take. This morning at work, I plugged it in and instead of charging, it got extremely hot and then it died.

This afternoon, I took it to the Sprint store and they put in a new battery and the phone worked again, but it got REALLY hot again. I took it back in and they looked at it again and said the phone has definitely got a problem and the cause of this is water. It has been raining, but I don't recall ever having any water get in the phone - just the occasional rain drop hits the screen and I wipe it off. I never keep it out in the rain. They are saying I'll have to do an insurance claim to replace it because of water damage. They say there are 4 water marks in the phone. I find this so hard to believe and don't like that they want me to spend $100 on a new phone.

Sprint HTC Hero :: Battery And Usage Statistics

Dec 18, 2009

I've been searching all over this forum as well as the internet on how people are using their HERO and the battery performance they're getting out of it. I've seen answers from 9 hrs with heavy usage to 36 hours with minimual usage. That's about all the detail I've been able to find. (Maybe I'm just not good at searching?)With that, I decided to do a little tracking of my own. I logged my usage and battery performance over a 27 hour period and thought I'd share it with the community. Not sure if this is even helpful but maybe it'll provide some sort of baseline for others to compare against.I recorded the battery level in % based on the stock battery meter, the time I recorded the battery level and any activity that occured between the current time and the previous time recording. For example, between 7:00AM and 10:19AM the battery dropped by 10% and I had received 2 emails, 2 calendar reminders went off and I had surfed the web for about 10 minutes.
