HTC EVO 4G :: How To Maintain Good Battery Life?
Jun 26, 2010
I'm interested in knowing how other people maintain good battery life with their evo. I get about 5 hours a day with moderate usage. I don't do much but put the screen brightness in the middle and occasionally going into "running applications" and closing the ones I don't need or use (most of them being the trashy default stuff); Turn off syncing when not needed; turn off GPS and other seetings that are not continuously needed to be left on.
I also configured my send and receive settings for each mail account. I know there is no official way to close out an app when your done using it, I usually just press the home button when i need to exit an app. Does everyone else do the same? Or is there a better technique to officially close apps and stop them running when you are done using them? Without DLing a task killer app cause I don't want one.? Feel Free to share your ideas or techniques.

My Christmas gift this year... the HTC Hero. Quite happy so far. However because neither my hubby (he has a Palm Pre) and I have ever had an android before, I have a few questions that he can't seem to answer. So please excuse the simiplicity of my questions
1)) What is the best way to maintain good battery life? Is there a specific % I should never let the batter fall below?
2)) Besides from being able to pull ringtones from my MP3 files on my PC, are there any good websites that offer free ringtones for android devices?
3)) My Hero came packed with a whole bunch of apps that I will never use. Like NFL Mobile, Nascar, Amazon and YouTube apps. Is it okay to delete these from my phone entirely? Will doing so free up memory for bigger and/or better apps?
4)) Are there any types files or apps that I should not put on my phone?

I can last a good 15 hours and still have like 50 percent. But when I don't use it the battery drains and barely lasts a day. I've been hearing that app killer is bad but if I don't use it I have no battery.

Did your battery life improve or get worse after the update? I did not update yesterday after reading about all the bricked phones. I got the message to update this evening but cancelled it for now because I absolutely need my phone tomorrow and because I am leery about what it will do to my near-perfect EVO. I get good to great battery life currently but do have some slight grounding issues. It would be nice to have those fixed and several report overall better performance.
But I have seen a few posts saying that battery life got worse, and the ones who say it is better are still not as good as I am currently getting. I got burned with an update once before (Samsung Moment 2.1 - supposed to make everything better but in reality made my decent battery life only half what it was before). So I wanted to get some input from those of you who have already done the OTA update - what are the results on the battery life?

So after all the horror stories about battery life I was kinda worried about my new Desire especially as I am a full brightness, 3G loving kinda man. But having got the phone on saturday, I have found it quite good. I mean, I played with it almost constantly for about 8 hours, and I still had 30% charge left.
Normal usage would be maybe an 2 hours or so per day, so i don't think there is any danger I'm gonna run outta juice at work. Also, when sleeping, I don't seem to lose any battery power at all, despite the experiences of others. Anyone else think the battery problems are overblown?

New to the Evo just wanted to know, when i first get it what should i do to get the best out of the batt life? Drain it then charge it, or should i just throw it on charge for some amount of hours first. I have heard different things from people and just wanted some tips.
Also at night when not using the phone should i turn the phone fully off does that help in anyway or is it OK to just have the phone on all the time and never turning it off.

Why does everyone seem to hate SenseUI? I find it beautiful and very smooth. I wouldn't want to remove it when I root my phone. I also get very good battery life after my recent battery tweaks.

OK I would really like some honest sound offs about the battery life on the Fascinate. I'll go first to get it rolling! After about a week with it, I'll say mine pretty much sucks! Its like its got worse! Seriously my evo and incredible both had better battery life. I tried going with out moving wallpaper today and it was about the same, example, left my house at about 10am this morning with a fully charged battery, with some moderate use I was down to 20 percent by 2:30? Not good in my book so far, so I'm wondering if I got a lemon? Also, Did anyone's phone come with the battery already installed inside the device? Mine did, and I've never seen that, the battery is usually in plastic wrap. Got it from a corporate store in NYC!

Recently switched from the Eris to the Droid thanks to Verizon and needed a crash course on Droid Roms. I am familiar with rooting for the Eris, but it seems Droid is a different beast. I have no issue rooting, I can figure that out from the posts. I just need help consolidating what ROMs to look at and what I should be looking for.
My priorities are:
1) Battery Life
2) Speed/Stability
3) Similar "look" to Droid, but doesn't has to be absolute
4) Ability to customize status bar, etc. I want to try my hand with Desktop Visualizer and create my own "theme" as it were for the phone.
That's really it. I realize having good speed and battery life may be a trade off, so focus more on battery life. The Droid is already way quicker than my Droid (even rooted), but who doesn't like a little extra speed?

I currently have the Samsung Galaxy (I7500). I have it for a year+ now. A couple of months ago I wanted to buy the Desire, but I decided its too early for an upgrade (big mistake). It's very hard for me to keep waiting for the perfect device since I hate my galaxy so much. So my question is which phone would you recommend?
IPhone 4 no way ofcourse, Samsung Galaxy S no way cause Samsung really screwed things up with the original galaxy (and it has no Flash), which leaves me with HTC Desire HD or Desire Z. The DHD has an extremely weak battery, and I want my next phone to last a day (moderate user). So, is the Desire Z worth the money? The things that bother me with the Desire Z are:
1. Weight - It weigh 180 grams! Thats sick, way too much. (the Desire is about 135, which isn't light, but not heavy either)
2. Battery life - I'm not sure how long does it last under moderate usage.
3. Size - its quite big, and its especially because of the keyboard, which I don't really need / care about.So, Whats your opinion?

If you're like a lot of Android users, you're obsessed with battery life and probably require a percentage widget. If you don't use a battery life widget, this probably isn't for you. I used to use Curve Fish's battery life widget which, in my initial testing months ago, didn't seem to affect battery life so I kept it and didn't think much about it.
My brother-in-law showed me a percentage indication that goes over the battery icon in the status bar on his Evo 4G. I found this hack for the Hero:
[PORT] Display Percent Battery Left within Battery Icon - Fresh 2.1.2+ - xda-developers
It adds the percentage remaining on top of your existing battery gauge in the status bar. Yes, root is required for this. At the time of writing this, I am at 14h 20m since unplugged and have 69% remaining. I would typically be between 47-53% remaining by this time. That equates to 3.5% drain per hour improved to 2.2% drain per hour. Which then comes out to around 60% increase in battery life without the loss of any features.

As per this post, An idea for great battery life
Could someone with good battery life on a Galaxy S post their batterstats.bin file?
I'd like to try this fix and not sure if the batterystats file would work from the other thread since its a different phone.

This has probably already been discussed, but I couldn't find anything. Do we need to periodically drain the battery completely to maintain it, or is it alright to charge it every chance I get?

The internal meter says it is due for charge long before its out of juice. Battery Left widget will give accurate voltage levels, but it too is fooled, even after proper calibration.

Does anyone else find that their battery does best at like 60%-70% charged and when it gets below 40 it moves a lot quicker? Also I've done 3 full drain and full recharges so far and my battery has improved sloightly each time, do you reccomend I do it again or is that just bad for the battery?

Background info:
- I'm running the "Battery Left" widget and I have it displaying "estimated percentage left", "system percentage", and "estimated time left until dead".
- I listen to A LOT of Slacker Radio.
My issues:
- I was previously getting about 19+ hours out of a fully charged battery. 2-3 days ago I started having issues with the widget (I think it may have started when I installed an update to the widget) so I recalibrated it to no avail. Then I uninstalled it and reinstalled it. Within a few hours it claimed that it was getting accurate readings (when I first installed the widget weeks ago, it took days to get accurate) and now says that I should be getting 9 hours out of a fully charged battery. I know that can't be right so I'll see how the widget adjusts itself over the next few days, but, any thoughts? (I know a lot of you guys use the same widget and know how it works...)
- Also, In the first two hours of my phone being unplugged this morning, it went from 100% to 70%. I did run Slacker for about an hour and a half of that time, but could it really drain the battery that much that quickly? And I noticed that when I close Slacker, if I go into phone settings, applications, running services - there's still a Slacker update thing running in there. Could that be draining the battery too, even if it's only checking for updates?
- I really don't run a lot of stuff on this phone. I keep wifi and gps turned off. I use bluetooth only a few hours each night. Minimal web browsing. Although, my POP email gets checked every 5 mins (but I just changed it to every 10) and I do use gchat and text a decent amount, but I'd say overall, it's "light" use (except for Slacker which could be a huge drain, right?)

My battery life was bad, but it was OK, but in the past few days my battery life is 10% per 30minutes(Just over 5 hours on a charge).I used to get 8-10 hours on a charge.I noticed last week that while it was charging the status of the battery was "Overheat".I think I somehow cooked the battery?I use TaskKiller and kill 95% of apps automatically, I have bluetooth,wireless,GPS disabled and the screen dimmed.I have not changed or installed any new apps.I have not changed the way I use the phone at all.My battery was dead, 0%, and it charged to 95% in about 45 minutes.Is this even possible?In fact in the past two days I have not gotten the charge above 95% at all.

Does anyone know which Sense ROM out there to use that has the best battery life? Or is there a Kernel? I currently am rooted with stock. I only rooted for wireless tethering and now I just want a ROM to have great battery life. Managing this battery has just become tiresome even with all the chargers I have. Not looking for tweaks and settings changes, just need a good ROM.

I rooted and put "Official Froyo HTC Sense ROM". Seems to work fine, however, I have a feeling that battery life is worse, especially when using the net. However, maybe it's just in my head. What are your experiences with battery life after upgrading to 2.2? And please, don't make silly "I surfed the web for 12 hours and still have 25% left" claims Also, I'm not interested in other ROMs, as I want a clean sense experience with no modifications (as close as possible to the way HTC made it)So - 2.2 and battery life: same, worse or better than on 2.1 that came with your Desire?

For those few whose battery life is actually not as good post-update have you figured out why yet? This is my first full day after doing the update last night and the battery is draining faster than it did before (even in standby). All settings are the same as before and I started with a 100 percent charge this morning. I am now down to 64% after 7 1/2 hours of light use. While that may sound like an improvement for some it actually isn't for me. Not a deal breaker but I would love to get my excellent battery life back (24-36 hours -- yes I am a light user especially when I am home a lot, which I am in the summer). The only thing different that I can see is that google talk doesn't stay disabled like it did before. Wifi is way down on the list of things using the battery and nothing seems out of place or not sleeping properly.

What started as a discussion over at XDA-Developers to try and resolve serious lag problems that some users experienced with their DHD is now proving to be a resolution to most of the problems reported with this device. Apparently turning 'usb debugging mode' ON is the resolution. The thread was first started by a user who noticed that whenever he was experiencing lag issues an Android process called /INIT was taking anywhere from 70% to 100% of his CPU usage. /INIT is a core process to the Android bootup sequence which should go 'dormant' after the bootup itself. What many users noticed after this was found is that whenever the lag problems started /INIT would take some 90% of the phone's CPU usage and not go back to its 'dormant' state. Even when the phone was idle and not being used. After applying the fix many people are reporting the phone running as smooth as they have even seen it running. Also users are reporting that recording video is no longer jerky and they can browse through the gallery smoothly and with no delays. The more relevant yet, and what may prove to be the best contribution from all this, is that some users are now reporting really amazing battery life performance. Its important to say that the so-called 'bug' doesnt seem to be HTC related but rather an Android 2.2 issue, as the performance issues are also being reported on other handsets running the latest Google OS - with some sources reporting that Google is soon to release an update to Froyo 2.2, possibly to resolve this bug. In order to turn 'usb debugging mode' ON go to: menu >> settings >> applications >> development.

First off, I didn't "find" this method on my own someone else did, I found it burred in other posts but it does seem to work for me. There are two ways to do this. One required you to dial a code into your dialer which I'll skip because the easy way is to just go to the Apps Market and get "Network" which is free. Then once you have it installed fire it up and scroll to the very bottom where you will see:
Set preferred network type. This is the VERY top option. If this is your first time running "Network" it's probably set to "GSM auto (PRL)".The problem here I've read is that Sprint does not have GSM networks so the phone keeps "searching" for GSM signals and it never truly sleeps. It might apprear to be sleeping but it's not, it looking for GSM signals.That said, change the setting to "CDMA auto (PRL)" which will set the phone to CDMA only and it will STOP looking for GSM networks and to go sleep like it's suppose to. That's if you have nothing else installed keeping it from sleeping.The only catch is, the setting does not appear to stick. If you reboot the phone, you have to restart "Network" and redo the setting. One thing to note is when you redo the setting, it will SAY it's still set to CDMA auto (PRL) but in fact it is not so just re-select the setting and close out of Network.I took my phone off the charger at 10am this morning and I've been using it on and off all day to send texts, Youtubed a couple video's made a 30+ minute call and a few other odds and ends. Normally I would have had to charge my phone again at least once threw out the day but I've NOT put it back on the charge since 10am and I was still at 83% power when I left work at 5pm.
