HTC Hero :: Battery Power Management
Aug 17, 2009
Searched the forum for an existing thread, and couldn't believe there wasn't one on this subject! I didn't expect the battery life to be great, but it's worse than I'd hoped,Obviously, setting the screen brightness to minimum is one way. I've also tried to see if you can 'turn off' applications which may be running in the background, but can't find a way to do this. My previous Nokias allowed you to see what programs were running, and you could turn them off to save battery power. I know a selling point of the Hero is that you can switch to applications quickly without 'loading them up', but is this killing the battery?

I went for a drive today and put the Evo on the mount I built for my car, plugged it in to the radio and also in to the car charger. I have Slacker Radio set to leave the screen on as long as it is connected to power. My battery was probably about 95% and during the drive, it was charging and, while listening to Slacker, the screen stayed on. However, not long before I reached my destination, my battery got to 100%, the green LED was on, and the screen would follow the 30 second shut off that my phone is set to. I could no longer get Slacker to recognize when the phone was connected to power. Anyone have a similar experience? I'm hoping this was isolated to that one instance (some perfect storm of other settings, use, etc), but I have a feeling it isn't.

I just bought a G1 from a friend and am exploring how I am going to use this. I am not much of a cell user, I want this more for the wifi access and am playing with Google Voice. I have a pay as you go call plan, no data plan, and am in a wifi zone about 90% of the time I would want to use it. All is functioning well.
I am finding that the battery barely makes it through the day even with light usage. The power manager indicates that about 15% of my usage is wifi, even when I didn't actually connect. I am thinking that the device is working hard scanning for an open connection. Like I said, 90% of the time I am in a known wifi zone with a "remembered" account. So it doesn't really need to be looking all the time. What would be really cool is if there's an app to toggle wifi based on location. I think by GPS since it would be more accurate. Wifi could be off until I get to a given location, then it would automatically fire up and connect.

Android has provided Power management framework for saving batterlife. But this is limited to screen/key lights. I am exploring ways to enhance this scheme for other use cases like camera, media playback by changing CPU frequency. I would like to know what support is available for this from Android kernel.

My application acquires and releases WakeLocks. What is the best way to test the app - i.e. is there a standard way to determine when the cpu is running (e.g. through a debug cable)?

Just read that some mobile phone battery chargers use power, even when there no phone connected to charge up. Does this apply to the charger for the Hero? I currently use a electrical timer switch for the Hero charger, but, am I wasting my time doing that?

I am ISO methods to conserve battery power on my Sprint HTC Hero.
I posted this thread in the Applications Forum:
WiFi - On & Off - Toggle App? Which is the best one?
ISO of a WiFi Toggle Switch so that I can turn WiFi On and Off as to avoid wasting precious battery power when I don't need to be searching for a WiFi connection.
Having this always on uses more battery consumption.
Correct?
Also, when Apps check for updates every 30 minutes vs. 4 hours, this consumes more battery power.
Correct?
So, here are some thoughts I have to reduce batter power:
Facebook Widget
I have the Facebook App and downloaded as well as the Facebook Widget.
See this video for info on the Facebook App:
www. youtube. com/watch?v=KcCpmwzL4T4
(remove spaces, I don't want to embed video here)
Questions
The facebook widget is pretty cool. It instantly updates my friends status and there's a quick-add update status text box.
However, I had the settings to check for updates every 30 minutes. Reduced this to 4 hours, but that was pointless since 4 hours is such a long interval I wound up going directly to the main Feed Home page to see the status updates list.
Is adding the Facebook Widget consuming more battery power because it's always on the Scene page, always running, always checking for updates?
Would removing the Facebook Widget save battery power?
I could simply make a shortcut for the Facebook App and open it when I want to waste time on Facebook to see how vain, narcissistic, and attention-starved my friends and colleagues are.
So, my key question here is would removing the Facebook App and only opening the program when I need it save battery power?
Twitter App
There's two options to place on the Scene. One is just a simple text update box, the other actually has a feed.
I'm using the former. Hence, it's not updating feeds and it's only being used when I enter text and hit send update to Twitter.
Also, I think I have my settings set not to check for updates.
I assume that because I'm using the non-Live-Feed option Widget on my Scene, this is not constantly checking for updates, and hence, not consuming a lot of battery power?
Correct?
Instant Messaging Programs
I have the Google Talk App, an Instant Messenger App (which has AIM, Yahoo, and MSN), and I recently downloaded the Meebo App (which has all of this plus others, including Facebook chat).
Meebo IM v21 Application for Android | Communication
I assume that by not running my IM App, or my Meebo IM App, and turning this off, this will save battery power. Correct?
Or, is it only consuming more power when I receive an incoming message. I imagine that the Meebo App, being connected to so many IM services, including Facebook, might be consuming more.
So, not leaving this on 24/7 would probably use less battery power.
Correct?
GMail App and Mail App for IMAP/POP
I have my GMail App setup. I'm getting notified each time I have an email in my Gmail Inbox. I've created a label - Inbox2 - to skip the inbox - for messages I want to read, but don't want to be instantly notified of.
I've decided not to use the Mail App - Connecting my Fastmail IMAP account on my phone because I believe this would involve running a second Mail App constantly checking for inbound mail updates.
See my post on Email and Mobile here:
http://androidforums.com/android-tips-tricks/15153-email-advanced-android-use-gmail-google-apps-fastmail-mail-clients-etc.html
By using only the GMail App and not using the Mail App for IMAP/POP, this is probably consuming less battery power.
Correct?
Question
What other steps, tips and tricks, can be taken to consume less battery power on the Sprint HTC Hero?

I currently have a personal (HTC Touch Pro) and business phone (iPhone). With Sprint now offering unlimited any-mobile (freeing up 1300+ minutes a month on my family plan) and Google Voice allowing me to get a separate business number, I'm thinking about dropping my iPhone, and replacing the HTC with either a BlackBerry Tour or a Hero. I work in project management; I know that the BB does have applications that would be useful to me (as does the iPhone), but I can't find comparable apps for Android. As a personal phone though, I would rather have the Hero. Given that I've only been able to spend a limited amount of time browsing the Android Market in a Sprint store, I was hoping someone here might know of some good replacements for my "must have" apps.
1) PIM / Task management. I have a lot of tasks, meetings, and deadlines to manage. I need something similar to the functionality provided by Outlook. I currently use Pocket Informant on the iPhone, which allows me to view multiple calandars, see my schedule from the month-level view, and integrate my to-do lists. I can also assign calander events and to-do tasks to projects, give them priority, provide extra notes, add multiple reminders, etc.. I could probably live with the Android's calander, but I definately need a good to-do app.
2) Time tracking. I have an app on the iPhone (TimeLogger) that lets me track how much time I spend on projects for clients. The one I currently use allows me to start a timer and then come back later to stop it, which is helpful but not a must.
3) Personal finance manager. I track all of my purchases, have several accounts / cards, and need to be able to track/filter business vs personal purchases.

I have a black background, I keep the display settings at the lowest brightness settings, and I keep the screen off when I'm not using it, but my phone is dying after 8-10 hours if I don't use it very much and 4-5 hours if I use it regularly. Every time it indicates that it needs to be recharged, 65-80% of the power is going to the display. I...don't see how that can be.I'm using a Samsung Vibrant that I bought on July 30th.

I'm coming from a blackberry where a "power off then back on" is different than a "battery pull" to soft reset the phone. But whats the deal with the Droid? Can I really just get away with "powering off then back on" instead of having to pull the battery to reset?

Just thinking, should the Push Gmail use less battery power than "Pull" such as Yahoo Mail. It would seem that the pull process is having to go look every 15 min and the Push process is merely sending it as it arrives.

I got the Behold 2 in the mail about four days ago, and it was working out pretty well for me. This was mostly because I'd previously been using an archaic piece of crap and hadn't had any experience with Android, so I was pretty blown away by the customization and yada yada yada. Touchwiz didn't even bother me because I've never seen Android without that UI. Then the battery issues started, which a few other people have obviously had judging by the threads on this forum. I was losing roughly 1% of battery power every 5 minutes without me even touching it, which is absolutely ridiculous. I followed the basic procedure and turned everything off, etc., and am recharging it now. So, waiting to see if it gets any better. But it seems like a hassle to have to constantly keep wifi disabled or to take all the widgets off the home screen......

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?)

Just called O2 about my Galaxy, It keeps shutting down and I cannot power up without first removing and replacing the battery, I's just over 1 month old and they deny any knowledge of this happening at all, They want me to send it for repair and have the priviledge of waiting up to 14 days to get it returned whilst I merrily pay a contract fee to them!
