Battery Life Solution

I am using the CDMA hero, but this should apply to anyone with a Hero (although our GSM friends have probably figured this out long ago.) Feel free to move my post if you like.
So I too was experiencing extreme battery draw down. I considered the SMS issue with perpetual awake times but after isolating the issue, I was still hitting 30% after after 12 hours with only moderate use. I found that unacceptable considering my Treo has been in standby for 2 weeks now and the battery has not budged. Solution? Turn of Google background services.
I know it hurts to have to manually refresh email, contacts, and calendar, but the return is almost zero battery drain (unless you are actively playing with the phone.) I know this is an obvious fix and I read it elsewhere online when I first got the phone. However, I am addicted to Gmail so I was really hesitant to turn it off. The background services option seems to keep a constant data connection when I really just want it to check my email every 15 minutes or so and update my calendar and contacts once a day. Has anyone found a way to limit the update frequency without the HTC widget. (I prefer the stock Android Gmail client.)

I do not know about the frequency of Gmail syncing,
but the main battery saving trick for me
is to turn the mobile data connection completelly off
when i know i will not (or want not) to be online
for a longer period of time (e.g. in the night, longer car drives, etc)
i am using the build-in htc widget for this

Thanks. That is a pretty good solution. Still wish I could curtail the sync frequency though......

So we need to re-enable it when we want to visit the Market, right? Annoying but if it improves battery life, then not a big deal.

How often do you recharge your Hero?

hi,
I would like to know how often you recharge your Hero?
With moderate to low usage I'm recharging every day and I'm thinking that autonomie on my Hero is really very bad. Before I used Polaris and I had to recharge every 2 or 3 days.
I'm thinking that maybe my phone have manufacture default. On official web page they say that autonomy on standby is 440 hours, its like 15 days, mine keeps barely 1 day, wtf!!!
Even during night when I don't use it all and put on plane mode battery loses 20%.
whitealien

i recharge everyday with mild usage. gaming - usually keep it plugged in.

with moderate usage i recharge my GSM Hero every 2-3 days. by moderate i mean, like 1h Wifi, 2h mp3, 0.5h phone usage, 1.5h online activity over 3G.
Thats about it. And even if i multiply the usage above by two, it will last two days.
During flightmode inthe night, it loses about 5-10%.
so it seems something is sucking really bad on your battery!
Cheers,
Chaos42

I would say I charge mine every 2-3 days. I'm a relatively low user but wifi is on all of the time and I use it for browsing a bit in the evenings when I don't have my PC turned on. GPS, mobile web and bluetooth is off for the most part.
My wife has the same phone and her battery life is a little shorter than mine but she has the mobile web on and uses hers a bit more then me so I would guess around 1.5-2 days.
My battery is rated at 1350mAh which I think is standard.

I have to charge it every day.
Unplug it from charger at 0700 and by 2200 it has less than 10% battery.
But I have WiFi on for over twelve hours a day, mobile web on and quite a few things updating online!

Background apps may be draining your battery
Hi whitealian,
Check the application list to see which applications are running in the background. One of them may be draining your power.
You can check the task list using Estrongs File Explorer (start the app, then menu->Task Manager). There are plenty of other task managers, of course...
In my case, I think it was ShopSavvy that was running in the BG. Once I removed it the battery performance was much better. See this post.
You can also use one of the apps that turn on/off wifi based on location. A quick market search finds "Y5 - Battery Saver". Haven't tried it myself yet!
Good luck!

Thanks for advice. I was not using ShopSavvy, but I had doubts that either I got faulty device or some app is draining battery.
I called customer service and they advice me to put phone in safe mode and test it for awhile. It extended a little my battery life, but still recharge every day. Next step was to reset to factory default. This is what I did yesterday and now I'm at the end of second day since last charge and I still have 40% left, what seems to be normal, but still a little to early to judge that everything is good.
I still don't know from where battery drain was coming. Probably from some app.
I'm putting my bet on NewsRob - google feed reader. It was the only app that was using network in background (apart from mail and tweeter sync).

too often. mostly once a day.
but when i'm at home im ususally plugging the as adaptor in either way, because i'm afraid to have to little battery left if i leave the house without a 100% battery level. (this can happen fast if you sync a lot of rss feeds, surf the net, have an exchange server connection and gmail push and so on...)
They really need to make better batteries. They should last 2-3 days on full force usage.

I wish it could

I think once every 2 days, but at night I have the ''phonestuff'' turned of using it as an alarm clock only. I do use the mobile internet connection all day. Tried once without that and got almost 4 days out of one charge.
I agree they have to make better battery's but I don't think the hero's that bad.
I had a diamond wich I had to charge almost twice a day when data was on...
So for me the hero's a big improvement.

I too get 2 to 3 days use out of a charge. Got rid of standard HTC Twitter client and replaced with Twidroid Pro. Only have Gmail push synchronization on.

I am pretty sure you are aware if the standard HTC SMS app battery drain issue?
Someone pointed out that HTCs SMS app constantly drains the battery, because it stopps the phone from entering standby mode. You can replace it by going into Applications menu, open "Messages", "Clear defaults" and install HandCent. As soon as a new SMS comes in, it will ask you which app you want to handle SMS messages. Choose HandCent, make it default and you are set.
Gave me a huge battery performance boost.

every day. that is the only bad issue of my hero.

I charge mine daily when I go to bed as it's usually giving me the 15% warning about 24hrs after I last charged it.
The joys of smartphones

At least once a day.
I've got a desk stand so it sit's in that for a constant juicing up, when im in the car I put it on to charge.. At work its on USB charge.. Basically I just juice it whenever I can..
I dont think theres anything wrong with yours.. they just have bad battery life.
If you think thats bad try the fossil palm powered watches.. i have to take it off every couple of hours to charge it!

Too often. Exchange, gmail, 1 additional pop3 inbox, facebook every 2hrs, twitter every 2hrs is enough for my phone to barelly hold a charge for a day. But when actually using the phone (music, calling), it doesn't hold even a day.

That's a US only thing though, right? The European ones don't suffer with that issue AFAIK.
...Which I'm glad about as I sometimes have to charge my hero twice a day. Data is on all the time when I'm out and I'm a pretty heavy user of it. In terms of calls perhaps an hour a day, and not a huge number of texts (more than ten would be unusual). I do use the phone to listen to music quite often too.
I think the apps in the background thing is what needs to be checked. I use a news widget and Facebook and Weather and a travel one which I think adds up to a lot of refreshes. I'm thinking about making a Sense Profile (or whatever it's called) that has nothing on the homescreens at all for times when I might want to be a bit more frugal with battery life.
I do think it's somewhat ridiculous that the phone is capable of doing so many things but that if you have it do them it withers and dies. I would've thought the way to calculate battery life would be to have the phone doing the things that people will want to do with it and work from there. It seems that battery life is calculated by turning the phone into as dormant a state as possible and then tip toeing around it trying not to disturb it.
I get by though.

Well, I cannot confirm that. I have a European one and mine drained the battery. I searched the net and with this trick I came from ~1 day to over 2 days with moderate usage and push enabled all the time.

My battery went even better once I configured Locale to go into airplane mode during night time and stopping sync services during work time. I don't need push when I am at work (timescal set, no GPS), because there I have all my mailboxes open and directly connected.

Some more tipps to improve battery performance.
Disable 3G - Set to "only 2G" in mobile network settings
Set display timeout to 30s or lower
Remove as many widgets from your homescreens as possible (I only have calendar)
use task killer app to check which apps are still running in the background and try to tweak their settings to not autoload or don't notify you on updates - and of course kill them
disable screen animations
uncheck WLAN for location checking
don't check your mailboxes too regular
disable vibration totally. disable haptic feedback for the keyboard as well

Battery Life?

I've had the HTC Aria for about four days now and my biggest issues is the battery drains to quickly. At first I attributed it to use because android phones prompt you to use them more often. However, even without use it still drains pretty rapidly. Does anyone know of a solution to this issue software wise. I have already turned off Bluetooth, GPS and Wifi. Are there other solutions

I got mine on Saturday, and I've actually gotten pretty good battery life out of it. I'm still in the habit of charging it every night, like I had to do with my old WinMo phone, but I think I could probably go two days without a charge. And that's with GPS / data always on, Wifi parts of the day, and pretty heavy use, since I'm always playing with it.
Have you tried something like Advanced Task Killer to keep apps closed that you aren't using? You can also adjust your screen brightness and timeout to try and save power.

It says that of my power is used by cellular idle or something like that 50% of it was used by that. Could it be my AT&T service

I don't get more than 10 hours out of mine. When I know I will be out all day, I turn the screen brightness almost all the way down to help conserve energy.

Good as it Gets.
With basic usage (some texting, a few calls and some market browsing or playing a game here and there) about 2 to 2.5 days without charging. Maybe the ones having issues with there phone sucking battery have to many widgets running.
In my current configuration I am only using 3 of my screens and only 3 widgets [favorites (small one), HTC clock/weather widget, and the HTC calendar widget (small)]. I have my work email checking every 30 minutes for syncing. I also have gmail and the default mail app pulling mail. I run ATK but only to kill apps on startup (cause it runs almost everything), other than that you don't need a task killer as you will have to reload these tasks next time and that will drain battery. I don't use it after that to kill anything. I am also running my screen at about 30% brightness.
Just some tips, widgets are nice, but they suck the battery life as well as constant updates. Check to see what you are running and disable/remove what is not needed or adjust sync times.

My battery life is fine. I got two days over the weekend with light usage. You need to look at what services are running and disable any widgets that you dont need. You may also want to look at the sync settings and turn off things you dont use (such as news). You do not need a task killer.

Also, see this post:
cranked said:
some quick tips:
1) disable market notifications - Market -> Downloads -> Notifications -> 'Don't Notify Me
2) Lower the sync times for your social network apps like twitter and facebook (or make them manual)
If you still suffer, have a look at some of the great tips HERE on the Cyanogenmod forums...ignore 1 and 3.

Also one might do *#*#4636#*#* then change phone setting from WCDMA to GSM .... Then that get little more out of battery...

It's critical that you turn off auto-sync; I have found that it absolutely destroys battery life.
Before I was losing maybe 5-10% every hour on standby, but ever since turning off auto-sync, I'm still sitting at 100% battery after 5 hours of standby.
Turning off mobile data/Wi-Fi doesn't make an impact on battery life, in my experience.

I edited your response..
Auto-Sync in itself is not going to be a problem.. Depends on what's syncing. EVERYONE will have different battery life because everyone uses their phones differently. Different configurations, different accounts used, different amounts of traffic on those accounts, not to mention actual usage patterns.

90% of people will have *slightly* different battery life.
5% of people will drain it fast.
5% will use it like a voice phone and might even get 16 hrs out of it.
But to turn off all apps makes for an invalid test because then you're testing the phone as if it were a non-smartphone, like a voice only phone.
I think the battery is too small for me and probably too small for most people. I look forward to fat batteries for this great phone.

My wife gets 2+ days out of hers... The battery is not that much smaller than my Nexus One, a more powerful phone, and I'm a power user with a lot of crap running including IMAP push mail, weather syncing... I look in at Market, Facebook, Twitter and manually sync those types of things etc.. I can easily get a full day out of it, off charger ~8am back on the charger midnight, 20-30% left. What I don't do is sit staring at my phone all day or play games for 8 hours at work, nor do I use it as a mp3 player..

Epic 4G Battery Life Tips / Mods / Recommendations

Just reviewed several posts and looks like there's not a lot of clarification on extending battery life on the Epic 4G.
Based on what i've read here, its possible to extend battery life with the following ?
GB update (sprint released rom or modded roms)?
Screen Dims, Auto syncing disabling, etc?
PRL update (not searching for towers)?
Data disablement?
I hope the GB and mod updates are the real answer.

The fact that anyone suggests to disable your data as a way to save the battery is mind boggling to me. Why would I have a smart phone if I had to disable data to save the battery (aside from maybe being on a plane or something where you HAVE to disable it anyway).

Look for randomking's thread in the Q/A section in epic development... the link is also in his signature, but he gives great advice on how to save battery properly.

I feel like I've tried everything but at this point I've resigned myself to poor battery life.
I have two Exchange accounts, gmail plus I use Yahoo and Live as well as a personal email account. Not to mention weather updates. I've got a 1amp charger in my car. A desktop cradle with a 1amp charger at my desk and another 1amp charger in a cradle on the table next to my favorite chair at home. At night I use the .5amp Samsung charger in a third cradle.
Basically, when I'm not using it its charging.
When I get up I automatically tap my belt case to make sure I don't walk off without it. I need it 31 and I need to know I get all email immediately and that I can be on a call for a couple of hours if I need to be.
But yeah, I wish I could just charge overnight and be able to depend on 24+ hours of battery life.

This is how I feel as well. I don't understand why you would want to have this phone if you are going to turn off all of its features. I don't undervolt. I am overclocked to 1400 and I have GPS on most of the time. I also use Bluetooth fairly regularly. I did spend $2 to get "Bloat Freezer" app to freeze the apps that run even when I am not using them. I also have a second battery. I can't obsess over the battery. I want performance and stability which I have. When changing ROMs, charge to full and wipe battery stats in recovery as well.

I'm looking to get another battery.
Right now I always have wifi on downloading stuff like 24/7 brightness all the way down(come on its not like you need it up anyway). I'm always overclocked to 1.2, and not undervolted and I don't use dark backgrounds, and have everything set to sync every 4-6 hours. I charge maybe twice a day never completely until night time.

If you live in a poor service area of town like I do, typically avg 3 bars all day, and often less...you are doomed.
I've tried all the tips, but the constant tower polling rakes my bettery over the coals. This is why I've adopted the multiple battery approach (with an external charger of course).

^^^ This. If not for rooting and Roam Control I'd have to almost not use my phone at work, and even then even Verizon's signal is low/spotty though to a much smaller degree in the building than Sprint's.

I do a number of things that are convenient for me.
I turn auto-syncing off. I don't need it always searching for updates in my life. I can spend the 3 seconds when I open the app.
I only put it on wi-fi/gps/4g when I need them. Sure, they can be on, but they use battery and it also takes seconds to turn them on.
I use auto-brightness. It works for me.

I do a lot of stuff:
- Leave GPS/wifi/4g/bluetooth turned off until I need to use them.
- Set screen brightness to the minimum, in both the OS and the browser.
- Use Titanium Backup's 'freeze' to disable bits of the OS I don't need, like 'DRM content'.
- Set up non-push email addresses to be forwarded to push email addresses (like gmail) automatically so that the phone itself does very little polling.
Doing all this, I can leave data on and easily have it last the day, every day, or turn data off and use it for a podcast player with BT headphones for a full eight hours.

Green power helps A LOT btw... its better than juice defender ultimate.

Bloat Freezer allows you to freeze apps like Titanium Pro although it seems like most people use Titanium

Freezing DRM saves a good portion for me. I also use Startup Cleaner to stop apps from automatically opening (not freezing) as soon as I startup my phone (swype, messaging, internet, etc). I'm not getting fantastic battery savings, but I've seen a difference doing this.

What is DRM?
http://developer.android.com/reference/android/drm/package-summary.html
It sounds like it would use some juice, but dunno that freezing may be most efficient for apps.

Dataswitch app by TomatoX. Its a widget that turns off 3G. I keep a Wifi on/off toggle on my homescreen as well. I connect often enough to get all my emails pushed through and what not so it doesn't feel like I'm crippling myself in the name of a little battery life. I went eight hours today and got home with 83% worth of battery. I prefer widgets over longpressing the power button personally.

These are a collection of the best suggestions I can make.
And no, turning data off is not one of them. Although disabling sync is.
DRM is a service for digitally verifying online store bought or rented audio/video. Itunes is a great example as the most annoying implementation of this concept. The problem is, that on our phones it runs constantly trying to verify files, whether you have any or not. If you don't think you need it, freeze it. Removing it completely has lead to problems. If you don't want to buy an app to do it, the terminal emulator commands are included in this thread.
PS: Currently I have not found one person that can top the best EC05 roms in battery life with a GB rom.

ok so i tried a couple of recommendations and i have some positive feedback!
I got green power and startup cleaner. After changing startup cleaner and using it to disable quite a few apps as well as drm and other non essentials it helped with my memory and apps running in the background.
I also tweaked green power settings to leave on the 3g and turned off the wifi on / off option (so i could do it instead of green power) and lt do its thing.
Excellent battery life. I left it on used it for a bit then let it sit and check a couple of emails, got a few pushed emails via gmail and did a few web searches.
i'm at 80% since 1pm. that's unbelievable yet that's the way it should be!
these apps / tweaks have helped. i do need push email and use push calendar from hotmail exchange.
i really wish the phone could do this on its own but i'll settle for this alternative using 2 apps at this time.
i hope gingerbread helps us all without the need for apps but i would probably still use them because of the substantial battery life gains.

Randomking is right.
All our efforts are minimal compared to what gb does....at least in cooked form
Rk..what custom rom do you recommed?

I think that's everybodys dream, to be ale to run this bad boy for 24 hrs straight. Unfrtunately were a long ways from that. Especialy from the way it sounds like you run your phone your going to becharging multiple times per day..that's just part of being a power user with a smartphone.
I gota agree though, fo the life of me i don't know why people disable data, or cripple thir phones ability just to eek out another hr of battery, this is a huge phone, with a big power hungry (beautiful) screen, you knew this when you picked it out. It can do pretty much any function that a laptop can. Use it like it was meant to be used, and dont fret so much over the battery.

Great News!
Battery life is now up considerably without the use of 3rd party apps.
I may consider using green power to get more extended battery life...but here's how i did it.
1. Update to EF02 Gingerbread OS (on a scale of 1 to 10 in terms of ease of upgrade...its a 2....1 being the most simple). It was as easy as download the app and let it upgrade your phone.
I'll post the video link here it was VERY Elementary folks.
2. Battery life in Gingerbread is great! Appears to have a better memory manager and much more smooth transition between screens, apps, etc.
Randomking was correct about battery life and adding all the apps we had to for Froyo just to get mediocre batter life.

A guide to a better battery life.

Hi
I see a lot of people on here complaining about the battery life on this phone, when in fact it's quite good. I have been able to pull off 3.30 hours SOT today with 40% left and 18 hours since unplugged with not even half the settings below (only turning off the things I don't use at all) and my Smart Watch connected with bluetooth all day.
I came from a Xperia Z3 before and of course it's nothing compared to that one (even tho, at times I get higher SOT) but the Galaxy S6 is also capable of way more.
When I first started with the phone, I was one of those that got barely 2 hours SOT so here I will write down the tips & tricks I gathered from reading on here and the things I found out myself.
First of, if you rooted, the cause could be no deep sleep. Check http://forum.xda-developers.com/galaxy-s6/general/battery-drain-root-twrp-to-fix-t3088860 by Meboy.
If you have deep sleep this might do it.
1. Disable voLTE as it's not really needed. Phoneapp -> More -> Disable it from there.
2. As this is a amoled screen, each background light, light up individually, so having a black background (and black theme in apps) safe a lot of juice.
3. Wifi -> More -> uncheck always searching for wifi.
4. Settings -> search -> Trust Agents -> Disable Smart Lock if not using it. It use quite some battery even when not used (no idea why).
5. Update Samsung Push Service from App Store.
6. Disable movements and gestures if not using them. Settings -> Movements and gestures.
7. My Google Services used way to much battery. I found the app, deleted the data and it came "back in control", so it's acceptable with the battery drain now.
8. The Gmail app use less juice than the stock Email app.
9. Sync, NFC, GPS and off when not using. I only have mobile data on all the time.
10. If in low coverage area of 4g, use HSPA instead (if good coverage). I barely notice any different in speed, but my phone use way less battery in deep sleep now. Still at 100% after 8-9 hours of sleep when on HSPA (good signal) from 4g (very bad signal) where it could use over 5% a night.
11. Settings -> Availability -> Direct access -> Turn on -> Grayscale on. 3 taps on the home button will turn Grayscale on, which greatly reduce the power your screen consume. No need to have it on all the time. But at times, when you know you gotta need the battery, turn it on by 3 clicks on the home button and your screen will use less battery.
12. The Facebook and Messenger app use quite a lot of battery. But I need the Messenger app, but I deleted and disabled the Facebook app (remember to disable it too, as - no idea why - it still used battery even tho I was logged out. As the Facebook app is stock on the S6) and just use the web browser Facebook app. Works fine.
13. Other apps I disabled is:
Drive
Facebook
Everything with Google in front of it. Google books, play, now, plus etc.

Just disable the apps you don't use.
14. Battery saver. If you don't want to have it on all the time, set it to a certain %, so that when your battery hit that % it turns on. Helps greatly improve battery life.
15. Greenify apps that run in the background, but no need to. Like
Dropbox
9gag
MyFitnessPal
Wordfeud
etc
Don't disable apps you use all the time, like Messenger, Chrome, Snapchat and so on, as you will not get any notifications and it use more battery opening them up all the time.
16. Instead of using auto-brightness, set it as low as you can tolerate.
17. Vibration off - Feedback, keyboard and ringing. Vibration use quite some juice.
18. Turn google location history off. Can't remember where, but a fast Google search will tell you.
19. Have been reports about high usage if restoring from old phone or google/samsung account.
20. Heard someone say this, but not sure what other side effects it have. But he said that you could disable Google Services, as there is a wakelock bug on 5.0.2 and it should work fine if not using other Google apps. But not sure on this one!
21. Widgets are cool, but they have a drawback. Some of them use quite some battery too, like weather apps.
I know some of those things will turn your phone into a dumb phone, but this is clearly tips to improve battery life. No need to use everything all the time. Turn off the things you can live with all the time and the rest you can turn off and on as you like and when you need it.
EDIT: Tasker is also pretty neat with secure settings if you know how it works.
Then your phone can automatically turn GPS on when opening apps that use GPS and turn it off afterwards.

Agreed! This phone have lasted me a weekend! 1-2 hours SOT a day, less than 1% battery loss for 10 hours standby time. It have just beaten my Xperia Z3.

Great thread it really helped a lot

Man although I'm very pleased with battery life already, this is an excellent guide bro. This should be stickied in my opinion.
